Objective. To analyze factors related to nutrition disorders about undernutrition and overnutrition in older people with the Mexican Health and Aging Study (MHAS), follow-up survey in 2018. Materials and methods. Cross-sectional relationships between social determinants, health relative factors and stressful life events with models for undernutrition and overnutrition among older people. Data were subjected to descriptive analysis and simple and multiple logistic regression models. Results. A total of 4 587 old people, undernutrition was 16% and relationship was found with =80 years, no partner, no schooling, overestimation of body mass index (BMI), motor difficulty, instrumental functional dependence, hospitalization in a previous year, and falls in the last two years, self-report prehensile strength of hand, report of a disaster affecting housing or an accident affecting health. The overnutrition was 43.6% and was related to women, aged 60 to 79, have =3 diseases, somatic symptoms, physical inactivity and underestimate their BMI. Conclusions. The factors related to nutrition disorders due to undernutrition or overnutrition are important interventions areas on aging. [ABSTRACT FROM AUTHOR]

pIntroduction. Physical changes during pregnancy trigger a positive or negative emotional response to the body image of the future mother. Since this response can affect the health of the mother and the fetus, it is necessary to have valid instruments to evaluate body image in pregnant women. Objective. To validate in Spanish the Scale of Attitudes towards Pregnancy and Weight Gain in Mexican population. Method. The study was conducted in two phases: it was culturally adapted to determine the linguistic validity and then its psychometric properties were verified through confirmatory exploratory factor analysis. Results. Participants included 520 pregnant women over 18 attending prenatal consultation, with a mean age of 23.56 ± 5.89 and with a mean of 33.20 ± 6.69 gestation weeks. The exploratory analysis defined five components that explain 56.04% of the total variance of the 18 items with acceptable internal consistency (a = 78). Factor analysis confirmed five factors (negative attitude towards the increase of gestational weight, positive body image, control of gestational weight, concern over gestational weight and restrictive behavior in response to gestational weight) with adequate fit indices (X2/gl = 2.57, IFI = .90, CFI = .90, RMSEA = .05 (90% CI [.048, .062], p =.12), SRMR = .05) Discussion and conclusion. The instrument has good psychometric properties and is recommended as a valid tool for assessing attitudes toward body image in Mexican women during the period of pregnancy. [ABSTRACT FROM AUTHOR]

The objectives of this study were to identify the predictive level that personality dimensions have on the students Body Image, as well as their possible relationships, and to compare such variables according to the sex of the participants. The study population were students of three technical careers at a public educational institution in the state of Jalisco, Mexico. The sample consisted of 567 students. The Body Shape Questionnaire was used to measure the Body Image. The Neo Personality Inventory Revised NEO FFI (reduced version of the NEO PI-R) was used to evaluate the personality. Regarding the results, a multiple linear regression analysis identified the predictive variables of the Body Image --unsatisfied--, the dimension of the personality called "Neuroticism" and the female sex. In addition, significant relationships were found between the dimensions of personality "Neuroticism", "Extroversion", "Kindness and Responsibility" with body image and significant differences in it according to sex. It is suggested that later studies include other characteristics that could explain the presence of Body Image dissatisfaction in adolescents and confirm the influence of the predictor variables identified.

The aim of this study is to obtain psychometric data for the evaluation of dissatisfaction with body image Questionnaire (Solano-Pinto y Cano-Vindel, 2010). A total of 411 Mexican university students participated (average of age = 20.65 ± 1.92 years) in this study. The factor structure of the questionnaire was analyzed trough exploratory and confirmatory factor analyses. Results showed a feasible and adequate structure of five factors (perceptual, emotional distress, behavioral, approach change and anxiety), with adequate fit indices of reliability and validity, according to statistical and substantive criteria. However, the obtained model does not fully coincide with that propose by the authors of the test, but continues giving support to the multifactorial component of body dissatisfaction. Future research should replicate these findings in wider samples. [ABSTRACT FROM AUTHOR]

Objective To determine which socio-demographic, anthropometric, ego functions, cognitive, affective, social and behavioral variables are associated and predict eating alteration. Methods A sample by quotas of Body Mass Index group: (50% overweight and obesity and 50% normal weight) was used. The questionnaires of Overeating and Ego Function Assessment were applied to a random sample of 20 to 40 years old women, resident in the city of Monterrey, Mexico (N=217). Results A model that takes as hypothesis overeating by affective alteration was contrasted. Affective alteration and greater age predict overeating; the last one leads to weight gain, to which the age also contributes. The affective alteration is predicted by ego functional deficiencies, primitive object relationships and higher education level. The weight gain generates corporal image preoccupation and motivation to lose weight (probably by physical and health problems). At the same time, the corporal image dissatisfaction, increased by affective alteration, motivates to lose weight. This model shows a good fit to the data (?2 [32, N=217]=38.14, p=.21, GFI=.97, AGFI=.94 y RMSEA=.03). Conclusions Ego function deficiencies lead to chronic problems of adaptation and relations, which generate affective alteration that is faced with self-indulgency in eating. The consequent weight gain increases the corporal dissatisfaction and the desire to lose weight. Diets and unresolved affective alterations can contribute in the future to an eating disorder.

Objective. Determine the relationship between the variables of self-esteem (SE), body dissatisfaction (BD), and body mass index (BMI) in a continuum of risky eating behaviors (REB) that ranges from normal behavior to the risk of eating disorders (ED), thus facilitating early detection of adolescents with ED symptomatology and the degree to which such variables have an influence. Methods. A total of 1 982 young women aged 15--19 were selected through stratified random sampling. Self-esteem (Pope, McHale, and Craighead scale), body dissatisfaction (Stunkard's Figure Rating Scale), and body mass index were measured. A brief REB questionnaire was administered. Three categories of REB were defined: no risk, moderate risk, and high risk. A multiple regression analysis was performed. Results. A direct relationship was found between risk of REB and BD, with significant differences between the groups (P < 0.001): no risk (83.6% of sample), 54.1% had BD; moderate risk (11.9% of sample), 84.8% had BD; and high risk (4.5% of sample), 89.9% had BD. There were significant differences in SE and BMI only between the group with no risk and each of the risk groups. Self-esteem played a role in predicting REB in all the regression models evaluated, whereas BMI did not. Conclusions. It is essential to identify adolescents at moderate risk of REB who have prodromic features of ED such as low SE and BD. When these features occur simultaneously, they can mediate a negative effect of BMI on REB. [ABSTRACT FROM AUTHOR]

Introduction Body image is a concept which involves the feelings, attitudes and perceptions people have about their own body, and is influenced by the adoption of social standards. Body image studies are used in the field of eating disorders research in order to analyze the degree of body dissatisfaction. However, most of the scales proposed to assess body image have been developed in Anglo-Saxon and European countries. Therefore, research on this topic in other socio-cultural contexts requires the standardization and validation of culturally adapted instruments. The aim of the present study was to determine and discuss the reliability and validity of a Mexican scale which measures body image. Additionally, comparisons regarding body dissatisfaction, internalization of the aesthetic ideal of thinness, social influence, age and Body Mass Index (BMI) were made between groups of female college students with and without disordered eating. Materials and methods The sample of this study comprised 508 female college students from the Universidad Autónoma del Estado de México, selected by means of a probabilistic stratification procedure taking into account the proportion of female students enrolled in each academic area of the university. Their average age was 20.1 years; their mean weight was 57.2 kg with an average height of 1.58 m, whereas the average BMI was 22.8. Based on the theoretical assumptions, three indicators were defined to structure the Body Image Scale: body dissatisfaction, social influence and the internalization of the aesthetic ideal of thinness, measured by a five-point Likert-type scale ranging from never (1) to always (5). A pilot study was carried out in a population of 100 college women; as a result, some adjustments were made in the instructions and in the order of the items. Additionally, a content validation was conducted through the judgments of four professional experts in the clinical mental health area. The scale contains thirty-three items; six of them refer to criticism and family pressure to maintain a slim silhouette and twelve address body dissatisfaction. The remaining fifteen items were taken from the Attitudes Towards Body Figure Questionnaire developed by Unikel, Gomez Peresmitré and Juarez. Results After using Kaiser-Meyer-Olkin's (KMO) and Bartlett's tests for establishing the factor structure of the instrument and obtaining a value of 0.94 (p<0.001), the composition of the final version of the scale consisted of twenty-six items grouped into three factors: Factor I: Body dissatisfaction, containing 10 items, with a mean of 3.1 (s.d.=0.8), accounting for 17.9% of the variance and with a value of Cronbach's Alpha of .84. Factor II: Internalization of the aesthetic ideal of thinness, including 10 items with a mean of 3.5 (s.d.=0.9) which explained 15.2% of the variance and with a value of Cronbach's Alpha of .89. Factor III: Social influence consisted of 6 items with a mean of 3.8 (s.d.=0.8), and accounted for 9.9% of the variance and with a value of Cronbach's Alpha of .82. A discriminant analysis was performed in order to determine if there were any differences according to body image and disordered eating and to establish the predictive validity of the scale. The results indicated that 13 of the 26 items correctly classified the body image scale in 98.2% of the original grouped cases and 97.4% of the cases grouped by cross-validation. A comparative analysis using Student's t-test was conducted among students who had high and low scores in BCCAR (Brief Questionnaire to measure Risky Eating Behaviors), yielding significant differences in their scores on all three factors of the scale. This indicates that women with disordered eating show significantly higher degrees of body dissatisfaction, internalization of the aesthetic ideal of thinness and social influence than women without disorder. Discussion The results of the study showed that the Body Image Scale has acceptable levels of validity and reliability, making it an adequate instrument for differentiating between women with and without disordered eating. The results reveal that high levels of body dissatisfaction were expressed in the majority of the sample, which is consistent with a previous study performed by Baile, Raich and Garrido in Spain, where 80% of the teenage girls expressed dissatisfaction with their body image. Lamerias et al. also found that 85% of the Spanish female college students were dissatisfied with their weight. A considerable degree of internalization of the aesthetic thin body ideal was observed in the sample, as a significant percentage of the participants with body dissatisfaction referred that body weight is important for getting nice clothes and that they are willing to do anything for a slimmer body shape. Also, physical appearance and body weight are deemed necessary for feeling fine. As the difference in body image in terms of eating behaviors risk is concerned, women presenting more risk obtained higher mean scores on the body dissatisfaction, internalization of the aesthetic thin body ideal and social influence factors, which could be a consequence of their perception of disapproval and body disgust. Troisi et al. also reported having found significant negative correlations between body image satisfaction and the presence of eating disorders. The findings of the comparison between body image dissatisfaction in terms of BMI showed that women with low weight are the least satisfied, followed by the ones who present obesity. This suggests that individuals with extreme thinness tend to have greater body image dissatisfaction, whereas Mirza, Davis and Yanovsi found that persons who are overweight or obese are the most dissatisfied. Regarding the internalization of the aesthetic thin body ideal and BMI, the highest scores were obtained in underweight women, followed by the obese ones. This is consistent with what Unikel et al. refer, mentioning that a thin body is socially perceived as more attractive, and also eating less is considered to be more feminine. It is concluded that, according to the results of the study, the proposed scale constitutes an adequate instrument for measuring body image in Mexican samples. Taking some items from already validated instruments proved to be useful for integrating all dimensions of the construct. However, it is considered necessary to obtain data on concurrent validity, sensitivity and specificity values in other samples and to determine cut-off points, in order to confirm its usefulness for research on body image.

The term «eating behavior» is immediately related to food consumption. However, eating is a complex behavior mediated by external factors. Eating is not exclusively related to satisfying individual's needs or nutritional requirements. Eating behavior alteration has originated disordered eating (DE) and eating disorders (ED), such as anorexia nervosa, bulimia nervosa and binge eating syndrome, where patterns of food ingestion are altered and people forget the importance of maintaining a balance between caloric ingestion and caloric expenditure, with repercussions in the nutritional status and in the individual's health. Recent studies carried out in Mexican population have confirmed the presence of DE, particularly among adolescents and young adults, and predominantly in females. Data from a representative sample of students with a mean age of 14.5 years reported an increase in the proportion of DE between the 1997 and the 2003 assessments (1.3% in males and 3.4% in females) compared to the 3.8% in males and 9.6% in females registered in 2003. More recent data from the National Nutrition and Health Survey 2006, in a representative sample of adolescents 10 to 19 years of age, indicated a prevalence of 0.8% (1% in females and 0.4% in males), with higher scores in the north and center-west areas of the country, followed by the central and south-south-east areas, with almost two-fold percentages in the urban settings compared to the rural ones. The multifactorial origin of ED is well known and among the most studied risk factors are: eating behaviors, high body mass index (BMI) and body thin-ideal internalization. Research findings indicate that overweight and obese adolescents are at more risk for body dissatisfaction, as their physical appearance is farther away from being as the one promoted by society and the media. The sociocultural pressure to be thin has promoted the internalization of the idea that being thin is synonymous to success, greater social acceptance, femininity (among females), self-control, and selfesteem. Based on the above, the main purpose of this paper was to evaluate the prevalence of DE and its relationship to body thin-ideal internalization and BMI in high school and college male and female students from an urban setting. An additional objective was to provide data on reliability and validity of the scales used in a sample of males, as well as additional validity data in females. Data analyzed in this research come from a larger study on risky factors associated to ED carried out in high-school and college students in the city of Pachuca, Hidalgo, during the 2007-2008 school years. After censing the school, a sample of 845 students was selected (381 males, 464 females), 45.1% was from high school, with a range of 15 to 17 years(X=15.82; D.E.=0.78), and 54.9% from college with a range of 18 to 23 years(X=19.81; D.E.=1.41) and that completed the questionnaires adequately.… [ABSTRACT FROM AUTHOR]

Objective: To analyse the psychometric properties, internal structure, and relationship with anthropometric indicators of the Body Shape Questionnaire (BSQ) among Mexican university students according to the measurement invariance approach., Methods: An instrumental study was carried out to assess the psychometric properties, validity, and reliability of the BSQ. The analysis of the measurement invariance was performed using the Least Squares Estimation, and weighted by adjusted variance and polychoric correlations after assessing different measurement models for BSQ in each group. The scores of the final version were correlated with anthropometric indicators by the Pearson correlation coefficient., Results: As regards the dimensional analysis, all of the previous models for BSQ have favourable adjustment rates, although those with a single factor show more robust evidence. The configural invariance was accepted; suggesting that the one-dimensional structure is common for both men and women. However, 16-item factorial loadings were statistically different between the groups. Hence, they were discarded and an 18-item version (BSQ-18) was obtained, which is considered invariant as regards gender. In addition, there is a direct relationship between the scores of the BSQ-18 version and the body mass index, waist circumference, and fat percentage. Satisfactory indicators were found as regards stability., Conclusions: The BSQ-18 can be used with men and women, and has high reliability indicators to be conducted in clinical settings to assess eating disorders and obesity among university students., (Copyright © 2018 Asociación Colombiana de Psiquiatría.
