- Abstract
Background: Maternal antioxidants intake and plasma total antioxidant capacity (TAC) concentration during pregnancy might influence on birth outcomes. This study was conducted to determine the association between dietary antioxidants intake and plasma TAC during pregnancy with birth outcomes., Methods: Overall, 220 mother-infant pairs were recruited in the first trimester of pregnancy. Maternal whole blood was collected and TAC was determined by the ELISA kit. Food frequency questionnaire was used to collect information regarding usual dietary intake. Birth size measurements including birth weight, length and head circumference were measured according to standardized protocols., Results: Energy-adjusted intake of beta-carotene in the first trimester of gestation [beta (SE) = 0.0002 (0.00008); p = 0.016] and energy-adjusted intake of vitamin E in third trimester of pregnancy [beta (SE) = -0.31 (0.15); p = 0.046] had significantly positive and negative associations with birth length, respectively. The maternal plasma TAC was positively correlated with birth weight in both unadjusted and adjusted models [beta (SE) = 2.75 (1.35); p = 0.043 and beta (SE) = 3.43 (1.50); p = 0.023, respectively]. In addition, the adjusted model showed a significant positive relationship between the maternal plasma TAC and birth length [beta (SE) = 0.023 (0.009); p = 0.01]., Conclusion: This study showed the positive association of maternal plasma TAC with birth weight and length. Moreover, maternal dietary intake of beta-carotene in the first trimester and vitamin E in the third trimester of pregnancy had significant positive and negative correlations with birth length, respectively., (© The Author(s) [2023].

- Abstract
Background: Limited experience exists on the relationship between anthropometric measures and dietary antioxidant intake in the pediatric age group. We aimed to investigate the association of dietary antioxidants intake and anthropometric measurement in children and adolescents., Methods: This nationwide study was conducted in 4270 children and adolescents, aged 6-18 years. Demographic and anthropometric data were assessed. Children and adolescents were classified as underweight, healthy weight or overweight/obese based on body mass index percentiles. Dietary intake was obtained by a 168-item semi-quantitative validated food frequency questionnaire. Energy and nutrients intake was estimated using the Nutritionist IV software. Dietary antioxidant quality score (DAQS) was calculated based on the daily dietary intake of selenium, zinc, vitamin A, vitamin C and vitamin E compared with daily recommended intake., Results: After adjustment for age, gender, living area (rural or urban), energy intake and physical activity level, DAQS was positively associated with waist circumference (WC), hip circumference and waist-to-height ratio (WHtR) in under-weight children and adolescents (B = 1.614, 1.634 and 0.01, respectively; all ps < 0.05). Increased DAQS was significantly associated with higher WC and WHtR in normal-weight children and adolescents (B = 0.536 and 0.003, respectively; all ps <0.05)., Conclusion: Dietary intakes of some antioxidants were higher in children and adolescents with excess weight. DAQS was correlated with some anthropometric measurements in under-weight and normal-weight subjects. It can provide a novel approach to assess the role of antioxidant intake on health promotion and diet-based therapies in under-weight and normal-weight children and adolescents., (© The Author(s) [2020].

- Abstract
We aimed to assess the association of sunlight exposure with sleep duration and sleep onset time in children. Data were obtained from the fifth survey of a national school-based surveillance program in Iran. Sunlight exposure time, sleep duration, sleep onset time, physical activity time, mental health status and frequency of consuming coffee and tea were recorded. Overall, 14 274 students aged 7-18 years were recruited. Sleep duration was associated positively with sex, age, body mass index and physical activity, as well as with sunlight exposure and negatively with the consumption of coffee and tea. Higher physical activity, exposure to sunlight and mental status score in children exposed to sunlight via their face, hands, arms and feet, reduced the likelihood of sleep onset time after midnight (odds ratio (OR) = 0.909, 0.741 and 0.554 respectively). Daily exposure to sunlight may increase sleep duration and advance the sleep onset time in children and adolescents., (© The Author(s) [2019]. Published by Oxford University Press.

- Abstract
Background: There are limited studies about the association of physical activity (PA) and screen time (ST) with psychiatric distress (PD) among children and adolescents including Iranian populations., Objective: We aimed to examine the independent and combined associations of PA and ST with PD among children and adolescents., Method: This school-based nationwide survey was carried out among 14 880 students (50.8% boys and 75.6% urban inhabitants), of age 6-18 years by cluster and the stratified multistage sampling method from 30 provinces of Iran. The students and their parents completed two sets of questionnaires obtained from Global School Health Survey with several questions about the PD. The time spent on watching TV/video and computer games and PA were assessed by self-administered validated questionnaires., Results: The study had a participation rate of 90.6%. Of the studied students, 45.85%, 83.62%, 37.81% and 23.92% had depression, anger, insomnia and worthlessness, respectively. The prevalence of confusion, anxiety and worry was reported in 19.6%, 55.17% and 75.31% of the students, respectively. The combined effect of PA and that of ST showed that students with high PA and low ST had the lowest prevalence of PD, while the highest prevalence of these PD was observed among students with low PA combined with high ST (p < 0.05 for all)., Conclusions: Increasing PA and reducing ST should both be considered for improving the mental health status of children and adolescents., (© The Author(s) [2018].

- Abstract
Background: Physical activity (PA) and weight status have been suggested as predictors of life satisfaction (LS) and perceived health status (PHS). Therefore the present study aims to investigate and compare the impacts of body mass index (BMI) and PA on LS and PHS in a population of Iranian children and adolescents., Material and Methods: This study was conducted in 2011-12 as a nationwide population-based study among 14 880 students of age 6-18 years. Students were selected via a multistage cluster sampling method from 30 provinces of Iran. Information on demographics, PA, PHS and LS was obtained using the World Health Organization Global School-based Student Health Survey (WHO-GSHS) questionnaire. PA values were considered as low (<2 /week), moderate (2-4 h/week) and high (>2 h/week)., Results: The current study has a participation rate of 90.6% (50.8% boys). PA was significantly associated with both LS and PHS [odds ratio (OR), 1.37 in both), while in BMI, this association was significant for only PHS (in underweight: OR, 0.65; 95% CI, 0.57-0.75; in excess weight: OR, 0.82; 95% CI, 0.73-0.93). In the combined group of BMI-PA, the influence of PA prevailed over the impact of BMI on PHS and LS, and therefore, PA was found to be the stronger factor., Conclusion: Although BMI and PA could both significantly impact LS and PHS, the stronger influence of PA on LS and PHS suggests that upgrading the 'activity level' of children and adolescents should be underscored and included on the agenda, rather than merely focusing on their BMI and weight status., (© The Author(s) [2018].

- Abstract
Cell blood counts are components of hematological parameters and indicators of pro-inflammatory states. They are proposed to be associated with metabolic syndrome (MetS). This study aimed to assess the relationship of the white blood cell (WBC) and the red blood cell (RBC) counts with components of MetS in the pediatric age group. The sample consisted of 300 children (152 boys) aged 6-12 years. Hierarchical Bayesian analysis of the bivariate Poisson regression model was used to estimate the effect of various components of MetS according to the cell blood counts. We found that RBC and WBC counts were correlated with the fasting blood glucose, the waist-to-height ratio, serum triglycerides and the blood pressure levels adjusted for age, the body mass index, gender, total cholesterol, low-density lipoprotein cholesterol and the hip circumference. The high-density lipoprotein cholesterol was correlated with the RBC counts based on 95% high posterior density regions for parameters in the Bayesian model. Our findings may serve as confirmatory evidence for the beginning of inflammatory process related to the cardio-metabolic factors from early life.

- Abstract
This study was performed to investigate the role of thiocyanate overload in the etiology of endemic goiter in schoolchildren of Semirom, Iran. A total of 1828 schoolchildren were selected by multi-stage random sampling. Urinary iodine concentration (UIC) and urinary thiocyanate (USCN) were measured in a group of these children. The median UIC was 18.5 microg/dl. The mean +/- SD of USCN in goitrous and nongoitrous subjects did not differ significantly (0.75 +/- 0.78 mg/dl vs. 0.63 +/- 0.40 mg/dl; p = 0.30). Finally, we concluded that neither iodine deficiency nor thiocyanate overload contributed to the high prevalence of goiter in Semirom. The role of other goitrogenic factors should be investigated in this region.

- Abstract
The objectives of the current study, that is the first of its kind, were to determine the prevalence of the hypertriglyceridemic waist (HW) phenotype in a nationally representative sample of children, as well as the metabolic risk factors identified by HW, and to identify lifestyle habits related to this phenotype. This national survey was conducted on 4811 representative school-students. We assessed the sensitivity and specificity of the HW phenotype for abnormal anthropometric and biochemical factors by using receiver operator characteristic curves. We determined the association of dietary patterns (obtained by factor analysis), physical activity level and some environmental factors with the HW phenotype. Overall, 8.52% of participants had the HW phenotype. Those children with the HW phenotype were more likely to have cardiovascular risk factors, notably for overweight and hypercholesterolemia. The dietary pattern characterized by junk foods increased the odds of having the HW phenotype, OR = 1.426 (95%CI, 1.109, 1.892), whereas the other dietary pattern including healthy foods decreased this odds, OR = 0.874 (95%CI, 0.765, 0.998). The risk of the HW phenotype rose with the consumption of solid hydrogenated fat as well as white-flour bread. Low education of parents and a positive family history of diabetes mellitus, obesity and or premature cardiovascular disease were the other risk factors for the HW phenotype. Low levels of physical activity significantly increased the risk of having the HW phenotype. The HW phenotype can be used as an accurate and easy tool for screening children at metabolic risk in population-based studies.

- Abstract
The Objective of the present study is to develop the first age- and gender-specific reference curves for waist and hip circumferences in an Asian population of youths. This cross-sectional population survey was conducted in 2003-04 on a nationally representative sample of 21111 school-students living in urban (84.6%) and rural (15.4%) areas of 23 provinces in Iran. After anthropometric measurements, smoothed reference curves for waist and hip circumference (WC, HiC) and waist-to-hip ratio (WHR) were developed by the LMS method. In both genders, WC and HiC percentile values increased with age. For girls, the 50th to 95th percentile curves for WC had a sharp increase between 8 and 13 years and 11-15 years, respectively, and began to plateau after this age, whereas for boys, these curves had a persistent and less sharp increase with age, until the age of 18 years. The WHR curves of girls decreased with age until 15 years and began to plateau thereafter, whereas for boys the 25th to 95th curves had a plateau pattern. Comparison of the current reference curves with the British ones showed that in boys, the 5th and 50th percentile curves were similar in both studies, but the 95th percentile curve of our study was higher than the British curves. For girls, the 5th percentile curves of both studies were similar, but the 50th and 95th percentile curves of our study were higher than the British ones. These curves represent the first childhood WC, HiC and WHR reference curves obtained in Asia. These curves can provide baseline data for analysis of time trends, as well as for international comparisons.
