This study aimed to determine the prevalence of and factors associated with postpartum depression and anxiety among mothers and fathers of preterm infants and to examine the relationships between maternal and paternal symptoms.Six electronic databases were searched to identify eligible studies reporting parental depression and anxiety within 1 year postpartum. Data were extracted for a random-effects meta-analysis to estimate the prevalence with 95 % confidence intervals (CIs). Subgroup and meta-regression analyses were conducted to analyze associations between study characteristics and prevalence estimates.In total, 79 studies were included. The meta-analysis of studies on mothers generated estimates of prevalence for depression (29.2 %, 95 % CI, 21.8 %-37.9 %) and anxiety (37.7 %, 95 % CI, 24.1 %-53.6 %). The meta-analysis of fathers indicated a pooled depression prevalence of 17.4 % (95 % CI, 12.5 %-23.8 %) and an anxiety estimate of 18.3 % (95 % CI, 8.1 %-36.3 %). Assessment time points and methods as well as the geographic continent in which the study was conducted were significant moderators of depression and anxiety. Significant inter-correlations were found between mothers' and fathers' depression and anxiety symptoms (p 0.05).Limited data from specific geographic continents, including Africa and Asia.Prevalence of depression and anxiety among preterm infants' parents was high, highlighting the need for early psychological screening and assessment. Further research is required to improve services that focus on parents' postpartum psychological needs in the family context.

To test the validity and reliability of the Chichewa Wijma Delivery Expectancy/Experience Questionnaire (W-DEQ) in Malawian postpartum women.A cross-sectional study of postnatal women (The participants had a mean age of 28.3 ± 6.7 years. A multidimensional structure containing three factors - a lack of positive feelings, fear and concerns about childbirth - with an appropriate model fit was reported for the CW-DEQ version. The Cronbach's α of the CW-DEQ was 0.87. The AVE and CR values were highly acceptable in lack of positive feelings - 0.17 (0.68), and concerns about childbirth - 0.79 (0.88) factors which proved the convergent validity of each; however, was marginally acceptable in the fear factor - 0.14 (0.53). Low range of correlations between the CW-DEQ constructs (In this study, we found the CW-DEQ to be a reliable and valid tool for assessing FOB in postpartum women.

To examine the associations of excessive internet use with depression, anxiety, and sleep quality among high school students in northern Vietnam, a country experiencing rapid economic growth.A cross-sectional study was conducted in a high school in northern Vietnam from July to September 2019. Symptoms of depression and anxiety were respectively assessed using the Center for Epidemiological Studies Depression Scale and the Vietnamese Anxiety Scale. Sleep quality was measured using the Pittsburgh Sleep Quality Index. Internet use and demographic characteristics were obtained using structured questionnaires. A multiple logistic regression was performed.In total, 678 participants with an average age of 16.1 (standard deviation 0.9) years were included. Nearly one-third of the adolescents (30.7%) exhibited excessive internet use (4 h/day), 19.6% experienced depressive symptoms, 14.5% presented anxiety symptoms, and 58.8% reported poor sleep quality. Compared to non-excessive internet users, excessive internet users (4 h/day) experienced significantly higher levels of depressive symptoms (p = .001), anxiety (p = .008), and poorer sleep quality (p.001). Students who were female and with fair/poor self-rated health experienced higher depression, anxiety, and poor sleep quality (p.05). After adjusting for demographic and health-related factors, students with excessive internet use were 58% more likely to experience poor sleep quality (odds ratio, 1.58, 95% confidence interval [1.06, 2.35]).Excessive internet use in Vietnamese high school students was significantly associated with poor sleep quality, but not with depression or anxiety.

This study aimed to evaluate the psychometric properties of the Breastfeeding Self-Efficacy Scale-Short Form (BSES-SF) in Indonesian postpartum women. We conducted a cross-sectional study including 237 postpartum women in Yogyakarta City, Indonesia. Participants completed the BSES-SF, Edinburgh Postnatal Depression Scale (EPDS), and Hospital Anxiety and Depression Scale (HADS). Construct validity, internal reliability, and divergent validity were examined using confirmatory factor analysis, Cronbach’s alpha, and Pearson’s correlations. We identified a unidimensional structure through confirmatory factor analysis with an excellent internal consistency by Cronbach’s alpha of .90. Divergent validity was evidenced by low correlation of the BSES-SF with the depressive symptoms (EPDS, r = −.21; HADS-D, r = −.17, p

Objectives The aim was to assess the effects of a parental sex education program on knowledge, attitudes, self-efficacy, and practices among immigrant parents. Methods A cluster randomized trial was conducted at immigrant activity centers in northern Taiwan. Recruited participants were randomly assigned to an experimental (four centers, n = 86) or control (four centers, n = 67) group. A practical booklet and a booster session were delivered. In total, 132 participants’ knowledge, attitudes, self-efficacy, and practice of parenting sexual education were examined at the baseline and 6 weeks after the intervention. Results After controlling for possible confounders, the posttest scores of self-efficacy of the experimental group were higher than those of the control group. The Johnson-Neyman procedure indicated that the intervention was effective for participants who had pretest knowledge, attitude, and practice scores of Conclusions An intervention with both practical booklet and booster session can improve knowledge, attitudes, self-efficacy and practices of parental sex education among immigrant parents. Practice implications In addition to practical booklets, health care professionals should provide booster sessions that meet the needs of immigrant parents to prevent sexual problems among children and adolescents at an early age.

Background High rates of early initiation and exclusive breastfeeding have been reported in Malawi, yet the underlying factors are unknown. Our objective is to examine the determinants of breastfeeding practices for mothers of infants less than 24 months old in Malawi. Methods A cross-sectional study was conducted using nationally representative data from the 2010 Malawi Demographic and Health Survey. Multivariate logistic regression analysis was used. Results Of 7282 women, 95.4% initiated breastfeeding within 1 hour after birth; thereafter 71.3% of women practiced exclusive breastfeeding, 6.1% predominantly breastfed, and 1.9% chose bottle feeding exclusively. The odds of early initiation were higher among women with frequent antenatal care visits and multiparous mothers. Similarly, frequent antenatal care visits and hospital delivery were positive determinants for exclusive breastfeeding. Infants at 6 months of age were more likely to predominantly breastfeed than they were at 1 month. The odds of bottle feeding were higher among women who were educated, who delivered at a hospital. Conclusions Optimal breastfeeding practices are highly prevalent in Malawi. Health care practice emphasizing frequent antenatal care visits that provide breastfeeding education and breastfeeding support in hospital care after childbirth are important for sustaining breastfeeding.

To evaluate the effects of an integrated childbirth education intervention on reducing childbirth fear, anxiety, and depression, and improving dispositional mindfulness.A two-arm parallel, single-blind randomised controlled trial.A teaching hospital in Northern Taiwan.Pregnant women ≥ 20 years of age with a singleton pregnancy (12-24 weeks gestation) and their support partners were recruited. All women included in the study had a score of ≥ 7 points on a fear of childbirth visual analogue scale.The intervention group (n = 53) received an 8-week course in a childbirth education programme, which included (1) childbirth education using simulation-based learning that highlighted coping with labour pain and (2) instruction in mindfulness breathing, body scans, stretching, sitting meditation, and mindfulness walking. Support partners were invited to participate. The control group (n = 53) received the usual standard prenatal care.The primary outcome of fear of childbirth was assessed using the Wijma Delivery Expectancy/Experience Questionnaire. The secondary outcomes of anxiety, depression, and dispositional mindfulness were assessed with the Edinburgh Postpartum Depression Scale, State-Trait Anxiety Inventory Scale, and the Mindful Attention Awareness Scale, respectively. Repeated data were collected at baseline, 36 weeks gestation, and 1 week postpartum.Ninety-one mothers completed the study, with a mean age of 33.9 years (SD = 4.4), and most were primipara (n = 83). The baseline measurements did not differ between the groups. Compared with the control group, there were significant differences in all measures from baseline for the intervention group: the scores were significantly lower for fear of childbirth (mean difference (MD) =-14.8 ∼ -23.7, p.01), symptoms of anxiety (MD =-7.4 ∼ -6.4, p.01), and depression (MD =-3.7 ∼ -3.5, p.01); the levels of dispositional mindfulness were significantly higher (MD =4.9 ∼ 5.7, p.01) at 36 weeks gestation, and 1 week postpartum.The 8-week integrated childbirth education intervention was effective in reducing the fear of childbirth in pregnant women. The mindfulness techniques were easily learnt and applied by the participants. Using these techniques during pregnancy and labour enhanced participants' mental health and coping. The integrated childbirth education which includes pregnant women and their support partners could be easily taught by midwives in other contexts.

Background Breast engorgement and breast pain are the most common reasons for the early cessation of exclusive breastfeeding by mothers. Research Aims (1) To examine the influence of breastfeeding educational interventions on breast engorgement, breast pain, and exclusive breastfeeding; and (2) to identify effective components for implementing breastfeeding programs. Methods Randomized controlled trials of breastfeeding educational interventions were searched using five English and five Chinese databases. Eligible studies were independently evaluated for methodological quality, and data were extracted by two investigators. In total, 22 trials were identified, and 3,681 participants were included. A random-effects model was used to pool the results, and a subgroup analysis and meta-regression analysis were conducted. Results Breastfeeding education had a significant influence on reducing breast engorgement at postpartum 3 days (odds ratio [OR]: 0.27, 95% CI [0.15, 0.48] p < .001), 4 days (OR: 0.16, 95% CI [0.11, 0.22], p < .001), and 5–7 days (OR: 0.24, 95% CI [0.08, 0.74], p = .013) and breast pain (standardized mean difference: −1.33, 95% CI [−2.26, −0.40]) at postpartum 4–14 days. Participants who received interventions had higher odds of exclusive breastfeeding. Breastfeeding educational interventions provided through lecture combined with skills practical effectively reduced breast engorgement (OR: 0.21; 95% CI [0.15, 0.28]; p = .001) and improved exclusive breastfeeding at postpartum 1–6 weeks (OR: 2.16; 95% CI [1.65, 2.83]; p = .001). Conclusions Breastfeeding educational interventions have been effective in reducing breast engorgement, breast pain, and improved exclusive breastfeeding. A combination of knowledge and skill-based education has been beneficial for sustaining exclusive breastfeeding by mothers.

This study applied the Theory of Planned Behavior to predict exercise behaviors and intentions of teenagers and analyzed sex differences.A prospective study design was employed to survey tenth-grade students in Taipei, Taiwan. The 951 participants reported their exercise attitudes, subjective norms, perceived behavioral control (PBC), and intentions, and their exercise behaviors were tracked 6 months later.Results revealed that 22.1% of all students and more male students than female students exercised for ≥30 min/day on 5 or more days/week. Hierarchical multiple regression analyses demonstrated that intentions, PBC, attitudes, and subjective norms explained 32.5% of the variation in exercise behavior (p.001). Intentions, attitudes, and PBC were related to exercise behavior regardless of sex. Attitudes, subjective norms, and PBC explained 67.0% of the variation in intentions (p.001). Attitudes and PBC were related to intentions regardless of sex.The findings support that the main constructs of the Theory of Planned Behavior can effectively predict regular exercise intentions and behaviors among adolescents.The results can serve as a reference for nurses and other healthcare professionals when formulating effective strategies to encourage adolescents to engage in exercise practices.

Background Perceived milk supply is an important modifiable factor for optimal breastfeeding. However, little is known about maternal perception of milk supply or how it impacts breastfeeding practices. The aim of this study was to examine relationships of perceived milk supply, maternal breastfeeding self-efficacy, and skin-to-skin contact with early initiation and exclusive breastfeeding among mothers of infants less than 6 months of age in Indonesia. Methods This was a cross-sectional study conducted in Yogyakarta City, Indonesia between August and October 2015. Maternal perception of milk supply was assessed using the Hill and Humenick Lactation Scale. Data on breastfeeding practices, and maternal and infant factors were collected using a structured questionnaire. Multiple regression and multivariate logistic regression analyses were performed to obtain estimates of associations. Results Thirty four percent of mothers had initiated breastfeeding within an hour after birth, and 62.4% of mothers were exclusively breastfeeding. High levels of perceived breast milk supply were reported in mothers who practiced skin-to-skin contact or rooming-in with their infants, experienced positive infant sucking behavior, or had high breastfeeding self-efficacy (p Conclusions In this study, skin-to-skin contact and breastfeeding self-efficacy are important determinants of perceived milk supply. Higher perception of milk supply was positively linked with exclusive breastfeeding. Our study highlights the importance of the assessment for mother’s perception of milk supply, maternal breastfeeding self-efficacy, and skin-to-skin contact in achieving optimal breastfeeding outcomes.

Low self-efficacy affects new mothers' ability to sustain breastfeeding. Interventions that increase self-efficacy could improve sustained breastfeeding.To develop an integrated breastfeeding education program based on self-efficacy theory, and evaluate the effect of the intervention on first-time mothers' breastfeeding self-efficacy and attitudes.A single-blind, randomised controlled trial.A prenatal clinic of a teaching hospital.First-time mothers with a singleton pregnancy (12-32 weeks' gestation) and their support partners were selected by convenience sampling (N = 104) and allocated by block-randomization to an intervention or control group.A 3-week breastfeeding intervention program was developed based on self-efficacy theory. The intervention group received the breastfeeding program; the control group received standard care. Data between groups were compared for scores on breastfeeding self-efficacy, infant feeding attitude, and breastfeeding practice, which were assessed using the Breastfeeding Self-Efficacy Scale-Short Form, the Iowa Infant Feeding Attitude Scale, and a structured questionnaire, respectively. Repeated data measurements were collected at baseline, 36-weeks' gestation, and postpartum at 1-week, and 1-, 3-, and 6-months.Ninety-three mothers completed the study. Data were compared for the self-efficacy intervention group (n = 50) with the control group (n = 43). Baseline measures did not differ between groups. The intervention group had significantly higher breastfeeding self-efficacy at 36 weeks' gestation (mean difference (MD): 7.3, p.001), and postpartum at 1-week (p.001), 1-month (p.001) and 3-months (p.01) with MD: 6.7, 7.9, and 8.1, respectively; differences in scores from baseline were also significantly greater from 36 weeks' gestation to 3-months (MD from 9.1~9.9, p.001) and 6-months postpartum (MD: 7.0, p.05). Infant feeding attitude scores significantly improved from 36 weeks' gestation to 6-months postpartum for the intervention group (MD from 3.5~7.4, p.05). Rates for exclusive and predominant breastfeeding postpartum were significantly higher for the intervention group vs control (p.02) at 1-week (98% vs. 86%), 1-month (100% vs. 90.7%), and 3-months (94% vs. 76.7%). Odds ratio (OR) postpartum for exclusive and predominant breastfeeding was greater for the intervention group at 3-months (OR = 4.7, 95% Confidence interval (CI), 1.2 -18.6; p = .05) and for exclusive breastfeeding at 6-months (OR: 2.82, 95% CI 1.0-8.1; p = .05).The breastfeeding education intervention improved breastfeeding self-efficacy, infant feeding attitudes, and exclusive breastfeeding rates. The breastfeeding education program could be effective for sustaining breastfeeding in new mothers.Registered with www.clinicaltrials.gov (NCT03807726).

Background Fear of childbirth is a common health concern for women during pregnancy. The Wijma Delivery Expectancy/Experience Questionnaire (W-DEQ) is widely used to measure childbirth fear during pregnancy. However, this instrument is yet to be validated in Malawi, Africa. Our study aimed to assess the psychometric properties of the W-DEQ questionnaire in Malawi. Methods Healthy pregnant women in the third trimester (N = 476) at a district hospital in Malawi were included. Fear of childbirth, depressive symptoms, and quality of life were assessed using the W-DEQ, the Edinburg Postnatal Depression Scale, and the World Health Organization Quality of Life scale, respectively. The construct validity, reliability, and convergent validity of the W-DEQ were examined using exploratory and confirmatory factor analyses, Cronbach’s alpha, and Pearson correlations. Results The mean age of participants was 28.2 (standard deviation = 6.8) years. Exploratory and confirmatory factor analysis of the Malawian version of the W-DEQ indicated a multidimensional structure with three factors: fear, negative appraisal, and a lack of self-efficacy, with acceptable goodness of model fit. The Malawian version of the W-DEQ showed a satisfactory internal consistency (α = 0.84) and was significantly correlated with depressive symptoms (r = 0.23, p r = − 0.17 ~ -0.26, ps Conclusions Our findings support the Malawian W-DEQ version being a reliable and valid instrument for measuring childbirth fear in African women.

The primary purpose of this study was to investigate changes in exercise intentions and behaviors among children across time. Then, we investigated how determinants in the Theory of Planned Behavior (TPB) predicted exercise intentions and behaviors, and explored if demographic predictors contributed to predicting behaviors.A three-wave, 12-month longitudinal study was conducted. A proportional stratified random sampling method was adopted, and 1997 children from 11 elementary schools in Taipei City were recruited. Numbers of participants were 1074, 1064, and 995 at times 1, 2, and 3, respectively.Children's exercise intentions and behaviors significantly changed (both p .05) during a 6-month interval. Attitudes, subjective norms, and perceived behavioral control (PBC) at time 1 could respectively explain 51.0% and 17.1% of the variance in time 1 and 2 intentions (FThe findings support the TPB model being suitable for use in longitudinal studies; its core constructs significantly predicted children's exercise intentions and behaviors.This study highlights that clinical practitioners and school nurses working with children can help youth engage in regular exercise by enhancing their intentions and perceived behavioral control, and cultivating positive attitudes and subjective norms when planning exercise intervention programs.

Objectives The primary goals of this study were to determine the effects of a physical activity intervention on the set-shifting aspect of executive function and to explore the potential mechanistic role of cardiac autonomic control, as assessed by heart rate variability (HRV), in the relationship between physical activity and executive function in obese young adolescents. Method Obese young adolescents were randomized either to participate in a physical activity program (n = 25) or to serve as the wait-list control (n = 25) for a 3-month intervention. Outcome measures included physical fitness, obesity status, executive function, and HRV; these measures were assessed at baseline and within 1 week of the conclusion of the intervention. Results The physical activity program improved the participants' physical fitness and obesity status. The program also improved executive function-related set-shifting performance, as measured by the total number of errors, and increased the HRV indices of normalized low frequency (nLF) and normalized high frequency (nHF). A positive correlation between the nHF time changes and the total number of errors was also observed. Conclusion These findings suggest that 3 months of a physical activity intervention effectively increase physical fitness and improve the set-shifting aspect of executive function in obese young adolescents. Furthermore, the physical activity-related alterations in cardiac autonomic control, particularly the parasympathetic response, may be associated with enhanced executive function.

Background Enhancing breastfeeding self-efficacy and intention is crucial for successful breastfeeding. Educational interventions highlighting breastfeeding self-efficacy and breastfeeding plans have been developed to help mothers initiate and sustain breastfeeding practices. Research aim This study aimed to determine whether the use of theory-based educational interventions, i.e., the theory of breastfeeding self-efficacy or theory of planned behavior, is associated with improved breastfeeding outcomes and to identify key factors of effective breastfeeding educational programs. Methods We used electronic databases and reference lists of articles to identify published randomized controlled trials of educational programs that adopted the breastfeeding self-efficacy theory or theory of planned behavior. Results In total, 24 randomized controlled trials were identified, and 5678 mothers were included in those studies, with 4178 mothers in the breastfeeding self-efficacy group and 1500 mothers in the theory of planned behavior group. Mothers who received theory-based interventions had better breastfeeding outcomes for up to 6 months postpartum (standardized mean difference =0.63, 95% confidence interval: 0.34~0.92 for self-efficacy scores at 1~2 months; odds ratio =1.82, 95% confidence interval: 1.27~2.61 for the exclusive breastfeeding rate at 1~2 months; and odds ratio =2.19, 95% confidence interval: 1.24~3.89 for the exclusive breastfeeding rate at 3~6 months). Mothers who were from non-Organization for Economic Co-operation and Development countries, were of older age, had participated in an educational program in a hospital setting, or had used an integrative class format had higher levels of self-efficacy and longer breastfeeding durations to 6 months. Conclusions Theory-based educational interventions are effective in improving breastfeeding self-efficacy and exclusive breastfeeding rates at 6 months. Future breastfeeding educational programs incorporating the theories of breastfeeding self-efficacy and planned behavior would be helpful in promoting sustained breastfeeding practices among mothers.

Objective To explore the quality of life (QOL) and related factors in early postnatal women. Design A descriptive, cross-sectional study. Setting Liwonde, Malawi. Participants Women who underwent a normal vaginal birth (N = 173) were included from August to September 2018. Measurements The QOL of participants was assessed using a World Health Organization QOL instrument. Demographic, obstetric, and health variables were collected using a structured questionnaire. Childbirth fear and depression were respectively assessed using the Wijma Delivery Experience Questionnaire and the Edinburgh Postnatal Depression Scale. A multiple linear regression was used to examine factors associated with the QOL. Results The mean age of participants was 29 (standard deviation 6.7) years. The overall QOL and health were satisfactory. The mean score of the QOL was highest in the psychological health and social relationships domains, followed by the environmental and physical health domains. A higher educational level was negatively related to the physical health of QOL (p ≤ 0.01), with physician care positively related (p = 0.01). The employment status was positively related to psychological health and the environmental QOL (p ≤ 0.01). Furthermore, a higher income, and physician care were positively related to the environmental QOL (p ≤ 0.05). High levels of childbirth fear and depressive symptoms were negatively related to all domains of the QOL (p ≤ 0.05), except for the social relationships domain. Conclusion and implications for practice The physical health QOL was lower in postnatal mothers in Malawi. Measures to improve physical health aspects and address women's fears and depressive symptoms during postpartum care are warranted. The findings should alert the health providers of the importance of assessing and improving women's physical health and psychological well-being during postpartum care.

Medication administration errors are common among new nurses. Nursing students might be less willing to speak up about errors because of a lack of knowledge and experience.To examine the effects of simulation training and problem-based scenarios on speaking up about medication errors among graduating nursing students.Prospective, controlled experimental study design.A university four-year nursing program in Taiwan.In total, 93 graduating nursing students in their last semester were recruited. Sixty-six students who received both a problem-based scenario and medication administration simulation training comprised the experimental group, while 27 students who received problem-based scenarios alone comprised the control group.Experimental group students underwent 2 h of simulation training. This training class was designed based on Kolb's experiential learning theory for knowledge development and speaking up about errors. Students in both groups administered medications in problem-based scenarios with eight embedded errors. Students' performance in speaking up about medication errors was directly observed and graded using an objective structured checklist. The McNeamer Chi-squared test, paired t-test, Z test, t-test, and Hedges' g effect size were conducted.The number of times participants spoke up about medication errors significantly improved in both the experimental group (pre-test: 2.05 ± 1.12 and post-test 6.14 ± 1.25, t = 22.85, p0.001) and control group (pretest: 2.04 ± 1.16 and post-test: 4.26 ± 1.63, t = 6.33, p0.001). However, after the intervention, the mean number of times participants spoke up about medication errors in the experimental group was significantly higher than that in the control group (t = 5.99, p0.001) in the post-test.Simulation training exhibited more-significant improvements than problem-based scenarios. Nursing schools and hospitals should incorporate simulation training or at least problem-based scenarios to improve medication safety.

Background Childbirth fear is a health concern in women living in high-income countries; however, little is known about childbirth fear among women living in low-income countries like Malawi. In this study, we explored childbirth fear and associated factors among pregnant and postpartum women in Malawi. Methods A cross-sectional study of 152 pregnant and 153 postpartum women was conducted at a district hospital in Malawi. Participants were assessed for childbirth fear using the Wijma Delivery Expectancy/Experience Questionnaire (WDEQ). Demographic and obstetric variables were collected using a structured questionnaire. The Multidimensional Scale of Perceived Social Support (MSPSS) was used to measure social support. Using a multinomial logistic regression, factors related to childbirth fears were examined, namely demographic and obstetric characteristics, and social support. Results The mean age of participants was 26 (standard deviation: 6.4) years. During pregnancy, 39% women reported a low level of fear, 41% reported moderate fear, and 20% reported high fear; while after birth, 49, 41, and 10% women reported low, moderate, and high fear, respectively. Pregnant women who were illiterate (odds ratio (OR): 5.0, p

Purpose This study aims to evaluate the executive function and learning attention in children with internet addiction (IA). Design and methods Children aged 10-12 were screened by Chinese Internet Addiction Scale to compose the IA group and internet nonaddiction group. Their executive functions were evaluated by Stroop color and word test, Wisconsin card sorting test, and Wechsler digit span test. Learning attention was evaluated by Chinese concentration questionnaire. Findings Executive function and learning attention were lower in the IA group than in the internet nonaddiction group. Practice implications Executive function and learning attention are compromised by IA in children. Early interventions into the IA should be planned to maintain the normal development of executive function and learning attention in childhood.

Background Sleep disturbances, such as insomnia, excessive daytime sleepiness, and poor-quality sleep, are common among nursing students and are closely linked with academic performance. Objectives To examine the prevalence of sleep disturbances and academic performances in male and female nursing students and to determine gender-specific effects on the relationship between sleep disturbances and academic performance. Design A cross-sectional study design was adopted. Settings This study was conducted in a school of nursing in Indonesia. Participants A total of 492 undergraduate students (103 males and 389 females) were included. Methods Data pertaining to the biosociodemographic characteristics, Pittsburgh Sleep Quality Index, Insomnia Severity Index, Epworth Sleepiness Scale, Morningness-Eveningness Questionnaire, and Beck Depression Inventory were collected from July 1, 2018 to September 30, 2018. Academic performance was measured using grade point average of the academic year 2017–2018. A multivariate logistic regression model was used for data analyses. Results The prevalence of poor sleep quality, insomnia, and daytime sleepiness was 66.0%, 45.6%, and 24.3%, respectively, in male nursing students and 71.5%, 52.4%, and 28.8%, respectively, in female nursing students. For circadian rhythm preferences, 66% male and 51.7% female nursing students were categorized as intermediate- and morning-type people, respectively. Insomnia was the only variable among sleep disturbances that significantly correlated with the risk of poor academic performance in female nursing students even after adjustment of covariates. Conclusions Sleep disturbances were highly prevalent among female and male nursing students, and insomnia was substantially associated with poor academic performance in female nursing students. Identifying sleep disturbances among nursing students and designing effective interventions to specifically target them are required to improve academic performance of female nursing students.

Aims and objectives To evaluate the effectiveness of an accessibility-enhanced multimedia informational educational programme in reducing anxiety and increasing satisfaction with the information and materials received by patients undergoing cardiac catheterisation. Background Cardiac catheterisation is one of the most anxiety-provoking invasive procedures for patients. However, informational education using multimedia to inform patients undergoing cardiac catheterisation has not been extensively explored. Design A randomised experimental design with three-cohort prospective comparisons. Methods In total, 123 consecutive patients were randomly assigned to one of three groups: regular education; (group 1), accessibility-enhanced multimedia informational education (group 2) and instructional digital videodisc education (group 3). Anxiety was measured with Spielberger's State Anxiety Inventory, which was administered at four time intervals: before education (T0), immediately after education (T1), before cardiac catheterisation (T2) and one day after cardiac catheterisation (T3). A satisfaction questionnaire was administrated one day after cardiac catheterisation. Data were collected from May 2009–September 2010 and analysed using descriptive statistics, chi-squared tests, one-way analysis of variance, Scheffe's post hoc test and generalised estimating equations. Results All patients experienced moderate anxiety at T0 to low anxiety at T3. Accessibility-enhanced multimedia informational education patients had significantly lower anxiety levels and felt the most satisfied with the information and materials received compared with patients in groups 1 and 3. A statistically significant difference in anxiety levels was only found at T2 among the three groups (p = 0·004). Conclusions The findings demonstrate that the accessibility-enhanced multimedia informational education was the most effective informational educational module for informing patients about their upcoming cardiac catheterisation, to reduce anxiety and improve satisfaction with the information and materials received compared with the regular education and instructional digital videodisc education. Relevance to clinical practice As the accessibility-enhanced multimedia informational education reduced patient anxiety and improved satisfaction with the information and materials received, it can be adapted to complement patient education in future regular cardiac care.

Positive schizotypy is associated with non-right-handedness, which includes left- and mixed-handedness. However, because the underlying mechanisms might be different, it is important to examine whether both left- and mixed-handedness are associated with a high incidence of schizotypy. During 2009-2010, we used both the Perceptual Aberration Scale and Schizotypal Personality Questionnaire to assess 1315 undergraduate students in Taiwan for schizotypy and the Annett handedness questionnaire to assess handedness. Among the three-way classifications based on Annett's grouping, the fully left-handed group appeared to have the lowest score of positive schizotypy; next was the fully right-handed group and then the mixed-handed. Among the three-way classifications driven from cluster analysis, mixed-handers showed highest score of positive schizotypy. When handedness was treated continuously, both direction (e.g., Hand Preference Index) and consistency (e.g., Either hand use score) indicators were significantly correlated with schizotypy. The results of regression analyses showed that the quadratic handedness measure were negatively associated with schizotypy. The results remained similar after correcting for social pressure on left-handedness. In conclusion, the relationship between schizotypy and mixed-handedness appears to be cross-cultural. The dichotomous classification of handedness, right- vs. non-right-handedness, appears to be insufficient. Additional studies on the distinct mechanisms of mixed- and left-handedness are warranted.

Title. Childbirth-related fatigue trajectories during labour. Aim. This paper is a report on a study identifying trajectories of childbirth-related fatigue intensity changes over time and the influencing factors related to specific trajectory patterns. Background. Childbirth is a period of time that encompasses considerable physiological and psychological fatigue, often having an adverse impact on women in labour. Empirical studies on this issue are scarce. How childbirth-related fatigue changes over time, and factors influencing fatigue development, remain unclear. Method. A prospective, correlational design with repeated measures was used. Data were collected by self-reported measures and laboratory analysis of blood specimens. From December 2004 to November 2005 a convenience sample of 209 low-risk pregnant Taiwanese women was followed throughout the labour process. Repeated measures of fatigue were analysed by using a semiparametric mixture model. Variables explaining trajectory class membership were identified by means of logistic regression. Results. Two distinct trajectories of childbirth-related fatigue were identified: low intensity (30·8% of women) and high intensity (69·2% of women). Fatigue level of both classes intensified following labour. The fastest period of fatigue-increasing rate was in the active phase. After birth, fatigue levels in the high-fatigue intensity class remained high. Primiparas in the high-fatigue intensity class experienced significantly more anxiety and higher lactate concentration at admission than the low-intensity class. Conclusion. Caregivers should endeavour to prevent high levels of fatigue once women enter the labour phase. Women who present with high fatigue at onset of labour should be targeted for early intervention, especially in the period of rapid fatigue increase.

Mixed-handedness, which has been associated with schizotypy in recent studies, might exist for at least two different reasons: it is innate or it has been forced. We examined whether the association between mixed-handedness and schizotypy differs depending on its source. We enrolled 3485 college students in Taiwan. We used both the Perceptual Aberration Scale and Schizotypal Personality Questionnaire to assess schizotypy, and the Annett Hand Preference Questionnaire to assess handedness. Two ways of classifying handedness were examined: the three-way classification based on Annett's categories and mixed- vs. non-mixed-handedness based on Degree of Handedness. Both mixed-handedness groups showed higher positive schizotypy scores. Among mixed handers, those who had been required to change their writing hand from left to right had higher positive schizotypy scores. Being forced to change writing hand seemed to be related to a higher level of schizotypy. The potential effect of the social pressure against using the left hand for writing is discussed.

BackgroundAfter cesarean section (CS), women may be at great risk for sleep disturbance, but little is known about temporal changes in their sleep patterns and characteristics. We had two aims: 1) to identify distinct classes of sleep-disturbance trajectories in women considering elective CS from third-trimester pregnancy to 6 months post-CS and 2) to examine associations of sleep trajectories with body mass index (BMI), depressive symptoms, and fatigue scores.MethodsWe analyzed data from a prospective cohort study of 139 Taiwanese pregnant women who elected CS. Sleep components were assessed using the Pittsburgh Sleep Quality Index in third-trimester pregnancy, 1 day, 1 week, 1 month, and 6 months post-CS. Data were collected on depressive symptoms, fatigue symptoms, and BMI. Sleep-quality trajectories were identified by group-based trajectory modeling.ResultsWe identified three distinct trajectories: stable poor sleep (50 women, 36.0%), progressively worse sleep (67 women, 48.2%), and persistently poor sleep (22 women, 15.8%). Poor sleep was significantly associated with pre-pregnancy BMI and more baseline (third-trimester pregnancy) depressive and fatigue symptoms. At 6 months post-CS, women classified as progressively worse or persistently poor sleepers showed a trend toward higher BMI (pConclusionsWomen had three distinct sleep-disturbance trajectories before and after elective CS. These poor-sleep courses were associated with BMI and psychological well-being. Our findings suggest a need to continuously assess sleep quality among women considering elective CS and up to 6 months post-CS.

Previous epidemiological studies have established insomnia as a major risk factor for mood, anxiety, and substance use disorders. However, the associations between insomnia with sedative-hypnotic prescriptions and various psychiatric disorders have not been thoroughly examined. The current study involved evaluating the risk of psychiatric disorders, namely schizophrenia, mood, anxiety, somatoform, and substance-related disorders, over a 6-y follow-up period in three groups: patients with insomnia and sedative-hypnotic prescriptions (Inso-Hyp), those with insomnia and without sedative-hypnotic prescriptions (Inso-NonHyp), and those with neither insomnia nor sedative-hypnotic prescriptions (NonInso-NonHyp).We used a historical cohort study design to compare the risk of psychiatric disorders among the three groups. Data regarding these patients were derived from reimbursement claims recorded in Taiwan's National Health Insurance Research Database. Cox proportional hazards regression was used to compare the 6-y risk of subsequent psychiatric disorders among the Inso-Hyp, Inso-NonHyp, and NonInso-NonHyp groups.Compared with the Inso-NonHyp and NonInso-NonHyp group patients, the Inso-Hyp group patients exhibited a higher risk of psychiatric disorders, particularly bipolar disorders (adjusted hazard ratio [AHR]: 7.60; 95% confidence interval [CI]: 5.31-10.89 and AHR: 14.69; 95% CI: 11.11-19.43, respectively). Moreover, among the Inso-Hyp patient group, insomnia prescribed with benzodiazepine, a longer duration of sedative-hypnotic action, and higher doses of sedativehypnotics were significantly associated with a higher risk of depressive and anxiety disorders.The Inso-Hyp group exhibited a higher risk of developing psychiatric disorders than did the Inso-NonHyp and NonInso-NonHyp groups. The results regarding patients with insomnia and sedative-hypnotic prescriptions associated with the risk of psychiatric disorders can serve as a reference for care providers when managing sleep disturbances.

Anxiety and fatigue adversely affect women's postpartum recovery, but few effective non-pharmacological interventions are known to relieve these two common and unpleasant symptoms.To examine the efficacy of an auricular acupressure intervention provided during early postpartum in reducing anxiety, fatigue levels, cortisol levels, blood pressure, and heart rate.A single-blind, randomised controlled trial.A 40-bed postpartum unit.Women who underwent caesarean section were randomly allocated to two groups: intervention (auricular pressure, n=40), and control (usual care, n=40).The intervention group received auricular acupressure on the shenmen acupoint twice a day (9 AM and 5 PM), and the control group received usual postpartum care. Serum cortisol levels were assessed by immunochemiluminescence, with blood pressure and heart rate assessed by electric sphygmomanometer. Anxiety and fatigue symptoms were assessed using the State Anxiety subscale of the State-Trait Anxiety Inventory and the Fatigue Continuum Form, respectively.Of the 76 women who completed the study, those who received auricular acupressure had significantly lower mean cortisol levels (mean difference=4μg/dl, p0.05), heart rate (mean difference=9.2 beats/min, p0.001), anxiety symptoms (mean difference=3.8, p0.01), and fatigue symptoms (mean difference=7.1, p0.01) than women in the control group at 5 days postpartum.Auricular acupressure is an effective non-pharmacological method for reducing cortisol levels, heart rate, anxiety, and fatigue in early postpartum after caesarean section.

Pain is common in patients after orthopedic surgery. The 11-face Faces Pain Scale has not been validated for use in adult patients with postoperative pain. To assess the validity of the 11-face Faces Pain Scale and its ability to detect responses to pain medications, and to determine whether the sensitivity of the 11-face Faces Pain Scale for detecting changes in pain intensity over time is associated with gender differences in adult postorthopedic surgery patients. The 11-face Faces Pain Scale was translated into Vietnamese using forward and back translation. Postoperative pain was assessed using an 11-point numerical rating scale and the 11-face Faces Pain Scale on the day of surgery, and before (Time 1) and every 30 minutes after (Times 2-5) the patients had taken pain medications on the first postoperative day. The 11-face Faces Pain Scale highly correlated with the numerical rating scale (r = 0.78, p.001). When the scores from each follow-up test (Times 2-5) were compared with those from the baseline test (Time 1), the effect sizes were -0.70, -1.05, -1.20, and -1.31, and the standardized response means were -1.17, -1.59, -1.66, and -1.82, respectively. The mean change in pain intensity, but not gender-time interaction effect, over the five time points was significant (F = 182.03, p.001). Our results support that the 11-face Faces Pain Scale is appropriate for measuring acute postoperative pain in adults.

Fatigue is not only a distressful symptom that is prevalent during labor; it may also interfere with the ability of laboring women to adjust to pain and bear down in the second labor stage as well as hinder maternal recovery and impair postpartum maternal-role performance. Childbirth-related fatigue is a frequent cause of physical and mental discomfort during labor and increases the likelihood of medical interventions such as instrumental delivery and cesarean section. Even so, as this fatigue is widely regarded as an inevitable part of the labor experience, little attention has been given to mediative interventions. In light of the above, this paper illustrates the definition and characteristics of childbirth-related fatigue during labor, analyzes the factors that affect this fatigue, and summarizes relevant nursing-care principles. It is hoped this paper increases nurse awareness of childbirth-related fatigue during labor and helps nurses take appropriate early prevention and intervention measures to reduce the adverse effects of fatigue and improve intrapartum care quality.生產疲憊：一個重要卻常被忽略的症狀疲憊不僅是常見於生產過程的不適症，亦為干擾產婦調適產痛、第二產程用力、產後復舊以及承擔母性任務等能力的重要因素。是已知易影響其身心舒適，甚至是提高器械及剖腹產機率的產時健康問題。雖然如此，卻常被視為待產必然的經歷，而未受到應有的重視。基於此，本文首先闡釋生產疲憊的定義與特性、分析影響生產疲憊的因素，並綜整生產疲憊的照護要點，以增加護理人員對生產過程疲憊的認識，進而能及早採取適當的預防和處理措施，減輕疲憊的不良影響，提昇產時照護品質。

BACKGROUND The Internet has been gaining worldwide popularity in recent years, but a loss of control over Internet use might lead to negative impacts on our daily lives. OBJECTIVES This study explored the effects of Internet addiction on autonomic nervous system function through heart rate variability (HRV) analysis. METHODS This was a cross-sectional design. Data were collected from 240 school-aged children who completed the Chinese Internet Addiction Scale and Pittsburgh Sleep Quality Index questionnaires. Spectral analysis was used to measure HRV. Independent t test was used to compare differences in characteristics and HRV between groups. A 2-way analysis of variance was used to examine group differences in HRV. RESULTS Internet addicts had significantly lower high frequency (HF) percentage, logarithmically transformed HF, and logarithmically transformed total power and significantly higher low frequency percentage than did nonaddicts. Internet addicts who had insomnia had higher low frequency percentage and lower HF percentage, logarithmically transformed HF, and logarithmically transformed total power compared with nonaddicts who did not have insomnia. CONCLUSIONS Internet addiction is associated with higher sympathetic activity and lower parasympathetic activity. The autonomic dysregulation associated with Internet addiction might partly result from insomnia, but the mechanism still needs to be further studied.

BackgroundThe present study aimed to (a) characterize 10-year trajectory patterns of depressive symptoms and (b) investigate the association between depressive trajectory and subsequent obesity, metabolic function and cortisol level.MethodIn a prospective study of Taiwanese adults aged ⩾60 years (n=3922) between 1989 and 1999, depression was assessed using a 10-item short-form of the Center for Epidemiologic Studies Depression Scale and information on body mass index (BMI) was collected by self-report. A subsample (n=445) of the original cohort in 1989 was drawn to assess metabolic variables and cortisol levels in a 2000 follow-up. After trajectory analyses were performed, multinomial logistic regression analyses were used to estimate the association estimates.ResultsWe identified four distinctive trajectories of depressive symptoms: class 1 (persistent low, 41.8%); class 2 (persistent mild, 46.8%); class 3 (late peak, 4.2%); and class 4 (high-chronic, 7.2%). The results from both complete cases and multiple imputation analyses indicated that the odds of obesity were lower in the class 2, 3 or 4 elderly, as compared with those in class 1, while the odds of underweight were higher. The classes of older adults with more and persistent depressive symptoms showed a trend toward having both a lower BMI (p=0.01) and a higher cortisol level (p=0.04) compared with those with low depressive symptoms.ConclusionsIncremental increases in depressive symptoms over time were associated with reduced risk of obesity and higher cortisol levels.

Background: Breast engorgement is a common problem that affects the initiation and duration of breastfeeding. Limited solutions are available to relieve the discomfort associated with breast engorgement. Thus, further investigation of methods to achieve effective relief of symptoms is critical to promote breastfeeding success. Purpose: The purpose of this study was to determine the effects of two breast caremethods, that is, scraping (Gua-Sha) therapy (administered to the experimental group) and traditional breast care (i. e., massage and heating; administered to the control group). Methods: A randomized controlled trial was conducted on 54 postpartum women at a Level Ⅲ medical teaching hospital. Participant inclusion criteria included postpartum breastfeeding women (a) who had an uncomplicated delivery and (b) who were experiencing breast engorgement problems. The Gua-Sha protocol selected appropriate acupoint positions, which included ST16, ST18, SP17, and CV17. Each position was lightly scraped seven times in two cycles. For the control group, we used hot packs and massage for 20 min in accordance with recommendations given in an obstetrical technique textbook. Results: Results showed no statistical differences between the two groups at baseline. Body temperature, breast temperature, breast engorgement, pain levels, and discomforting levels were statistically different between the two groups at 5 and 30 min after intervention (p＜.001). The results of generalized estimating equation analysis indicated that, with the exception of body temperature, all variables remained more significant (p＜.0001) to improving engorgement symptoms in the experimental group than those in the control group, after taking related variables into account. Conclusions and Implications for Practice: Our findings provided empirical evidence supporting that Gua-Sha therapy may be used as an effective technique in the management of breast engorgement. By using Gua-Sha therapy, nurses can handle breast engorgement problems more effectively in primary care and hence help patients both physically and psychologically.

In this ongoing longitudinal study of adolescent twins/sibling pairs and their parents in Taipei, we aimed to investigate the genetic and environmental influences on adolescent behavioral development, metabolic risk factors, and the associations between the two. Special focus is on anxious depression, metabolic profile, and hormonal factors such as cortisol and leptin. The first wave of assessment was completed during the period of 2002 to 2005 and included 192 twin pairs, 6 triplets, 56 sibling pairs and their first-degree relatives (484 parents and 142 siblings). We are currently in the process of a second wave assessment as follow-up. Dimensional psychological assessments using self-report questionnaires, as well as categorical assessments based on semistructured clinical interviews, were performed. All subjects received a 2-hour oral glucose tolerance test at the examination site. The metabolic phenotypes including body mass index, blood pressure, levels of glucose, insulin, and lipid profile as well as related hormonal levels were measured. Zygosity was determined using DNA, except for a few twins whose DNA was not available. Such a combination of detailed psychological assessments and metabolic function tests is expected to help shed light on the interrelation of psychological well-being and metabolic functioning.

BackgroundDepression and anxiety are important mood changes in childbearing women. However, changes in depression and anxiety over time in women who undergo an elective cesarean section (CS) have not yet been elucidated. We aimed to characterize the trajectories of depressive and anxiety symptoms, and patterns of co-occurrence, and examined the associated predictors of depression and anxiety courses.MethodsA prospective longitudinal study of childbearing women (N = 139) who underwent a CS was conducted. Depressive and anxiety symptoms were respectively assessed using the Edinburgh Postnatal Depression Scale and State Anxiety Inventory, in the third trimester and at 1 day, 1 week, and 1 and 6 months postpartum.ResultsGroup-based modeling identified three distinct trajectories of depressive symptoms: group 1 (low, 30.9%), group 2 (mild, 41.7%), and group 3 (high, 27.3%). Four group trajectories of anxiety symptoms were identified: group 1 (low, 19.4%), group 2 (mild, 44.6%), group 3 (high, 28.8%), and group 4 (very high, 7.2%). Mild symptoms of both depression and anxiety were the most common joint trajectory. Depression trajectories were significantly related to anxiety trajectories (pConclusionsDistinctive trajectories and co-occurrence patterns of depressive and anxiety symptoms were identified. Our findings suggest a need for greater attention to continuous assessment of psychological well-being among women who undergo an elective CS.
