"Healthy Habits, Healthy Girls-Brazil": an obesity prevention program with added focus on eating disorders.

PURPOSE: To evaluate the immediate post-intervention and 6-month post-intervention effects of a Brazilian school-based randomized controlled trial for girls targeting shared risk factors for obesity and disordered eating. METHODS: Total of 253 girls, mean of 15.6 (0.05) years from 1st to 3rd grades of high school participated in this 6-month school-based cluster randomized controlled trial. "Healthy Habits, Healthy Girls-Brazil (H3G-Brazil)", originally developed in Australia, emphasized 10 key nutrition and physical activity (PA) messages delivered over 6 months. Disordered eating prevention procedures, i.e., prevention of weight-teasing, body satisfaction, and unhealthy weight control behavior, were added to the intervention. Body dissatisfaction, unhealthy weight control behaviors and social cognitive-related diet, and physical activity variables were assessed at baseline, immediate post-intervention, and 6-month post-intervention. Intervention effects were determined by one-way analysis of covariance or logistic regression, after checking for the clustering effects of school. The control group did not receive intervention prior to follow-up assessment. A conservative significance level was set at p < 0.01. RESULTS: Beneficial effects were detected for PA social support (F = 6.005, p = 0.01), and healthy eating strategies (F = 6.08, p = 0.01) immediate post-intervention; and healthy eating social support (F = 14.731, p = 0.00) and healthy eating strategies (F = 5.812, p = 0.01) at 6-month post-intervention. Intervention group was more likely to report unhealthy weight control behaviors (OR = 1.92, 95% CI 1.15-3.21, p = 0.01) at 6-month post-intervention. No other significant immediate or 6-month post effects were detected. CONCLUSION: H3G-Brazil demonstrated positive 6-month effects on some social cognitive variables but an adverse effect on unhealthy weight control behaviors. Thus, this study was not able to achieve synergy by combining obesity and disordered eating prevention procedures in an intervention among low-income girls in Brazil. TRIAL REGISTRATION: Level I: cluster randomized controlled trial.

Attitudes toward health and taste of food among women with bulimia nervosa and women of a non-clinical sample.

Taste preferences and health concerns play important roles in determining eating attitudes, thus influencing food choices. Disordered eating attitudes are common among women, and can lead to the development and maintenance of eating disorders (ED). Attitudes toward health and taste of food among ED patients and its comparison with non-clinical women are not well known, and this knowledge could improve eating interventions. In this study, we compared taste preferences and health concerns in 27 women with diagnosis of bulimia nervosa (BN) and 216 women of a non-clinical sample. All participants completed the Health and Taste Attitude Scale (HTAS). Using analysis of covariance we compared the HTAS scores of the BN patients with those of the college students. Risk behaviors for ED (assessed by the Eating Attitudes Test) were identified in 54 (25%) of the non-clinical sample, all of whom were therefore excluded in comparison of BN patients. Non-clinical sample, compared to patients, scored higher on the HTAS Taste domain (p < 0.001) and its pleasure subscale (p < 0.001), whereas patients scored higher on the HTAS Health domain (p < 0.05) and its light product interest subscale (p < 0.05). Based on our data, eating attitudes of women of non-clinical sample are related to taste and pleasure, whereas women with BN are concerned with adopting a diet regarded as healthy, thus increasing their interest in "light" products. Therefore, the taste and health concerns must be considered in nutrition interventions for women in general, and prevention and treatment of ED as determinants of food choice.

Preventing obesity among Brazilian adolescent girls: Six-month outcomes of the Healthy Habits, Healthy Girls-Brazil school-based randomized controlled trial.

BACKGROUND: School-based trials to prevent and reduce prevalence of pediatric obesity in low-income countries are necessary. In Brazil, addressing adolescent obesity is a public health priority. OBJECTIVE: To evaluate the impact of a group randomized controlled trial involving a 6-month multicomponent school-based obesity prevention program targeting adolescent girls. METHODS: The Healthy Habits, Healthy Girls-Brazil program recruited participants (n=253; 16.05±0.05 years) from ten eligible public technical schools in São Paulo, Brazil. The program was adapted from an Australian intervention study, which is based on the Social Cognitive Theory. The primary outcome measure was body mass index (BMI), and secondary outcomes included BMI z score, waist circumference, and various sedentary and dietary health-related behaviours. RESULTS: Although changes in BMI were not statistically significant, differences favored the intervention group (adjusted mean difference, -0.26kg/m(2),se SE=0.018, p=0.076). Statistically significant intervention effects were found for waist circumference (-2.28cm; p=, p=0.01), computer screen time on the weekends (0.63h/day, p; p=0.02), total sedentary activities on the weekends (-0.92h/day, p<0.01), and vegetable intake (1.16servings/day, p=0.01). CONCLUSION: These findings provide some evidence for the benefit of a school-based intervention to prevent unhealthy weight gain in adolescent girls living in low-income communities.

Fluoride intake from food items in 2- to 6-year-old Brazilian children living in a non-fluoridated area using a semiquantitative food frequency questionnaire.

BACKGROUND: Estimating fluoride intake (FI) using the 'duplicate plate' method is difficult and can raise ethical dilemmas. AIM: To apply a semiquantitative food frequency questionnaire (FFQ) to 2- to 6-year-old Brazilian children in a non-fluoridated area (i) to estimate their FI and (ii) to provide additional validity to the questionnaire by comparing the results obtained with those found previously in a fluoridated municipality. DESIGN: The FFQ was administered to parents of 398 children residing in a non-fluoridated community. Constituents of the diet were divided into solids, water and other beverages and their fluoride content was analysed with the electrode. Data were analysed using unpaired t-test. RESULTS: The mean (±SD) FIs from solids, water and other beverages were 0.009 ± 0.004, 0.001 ± 0.001 and 0.007 ± 0.007 mg F/kg body weight/day, respectively, totalling 0.017 ± 0.009 mg F/kg body weight/day. Total FI from food/beverage items ingested in the non-fluoridated area was significantly lower than that observed in a study previously conducted in a fluoridated area (P < 0.0001). CONCLUSIONS: This result reinforces the use of the FFQ as a promising alternative to duplicate diet in order to estimate FI in children in this age range, with potential application in broad epidemiological surveys.

Psychometric evaluation of the Disordered Eating Attitude Scale (DEAS). English version.

UNLABELLED: Eating attitudes are defined as beliefs, thoughts, feelings, behaviors and relationship with food. They could influence people's food choices and their health status. OBJECTIVE: This study aimed to adapt from Portuguese to English the Disordered Eating Attitude Scale (DEAS) and evaluate its validity and reliability. The original scale in Portuguese was translated and adapted into English and was applied to female university students of University of Minnesota-USA (n=224). Internal consistency was determined (Cronbach's Alpha). Convergent validity was assessed by correlations between Eating Attitude Test-26 (EAT-26) and Restrain Scale (RS). Reliability was evaluated applying twice the scale to a sub-sample (n=30). The scale was back translated into Portuguese and compared with the original version and discrepancies were not found. The internal consistency was .76. The DEAS total score was significantly associated with EAT-26 (r=0.65) and RS (r=0.69) scores. The correlation between test-retest was r=0.9. The English version of DEAS showed appropriate internal consistency, convergent validity and test-retest reliability and will be useful to assess eating attitudes in different population groups in English spoken countries.

Development and validity of the Disordered Eating Attitude Scale (DEAS).

The aim of this study was to develop and validate the Disordered Eating Attitude Scale to measure disordered eating attitudes, defined as abnormal beliefs, thoughts, feelings, behaviors, and relationship regarding food. Exploratory factor analysis was performed and internal consistency assessed in a sample of female university students (N=196). Convergent validity was acceptable based on statistically significant correlations with the Eating Attitude Test-26 and Restraint Scale. Known-groups validity was determined by comparing the student sample's mean scores against scores of an eating disorder group (N=51). The Disordered Eating Attitude Scale comprises 25 questions and five subscales explaining 54.3% of total variance. The total scores differentiated student, bulimia, and anorexia groups. The scale should prove useful for evaluating eating attitudes in various population groups and eating disordered patients.

Brazilian Children's Dietary Intake in Relation to Brazil's New Nutrition Guidelines: a Systematic Review.

PURPOSE OF REVIEW: This systematic review reports the latest scientific evidence, from cross-sectional and cohort studies, describing the dietary intake of children and adolescents from Brazil. The goal of the review was to describe intakes according to Brazil's new food classification system (NOVA) which classifies foods according to the degree of processing, i.e., unprocessed/minimally processed, processed culinary ingredients, processed food, and ultra-processed food. Due to a paucity of data using the NOVA classification system, studies with other intake descriptors were included. RECENT FINDINGS: Results using the NOVA system showed a somewhat high intake of (ultra-)processed items, than of minimally processed items. Studies using other methods of dietary assessment showed not only high intake of sources rich in fat, sugar, and sodium, most of them processed items (e.g., savory snacks and sweets) but also intake of fruit, vegetables, and whole grains. Overall, the literature was marred by inconsistencies and variation in study definitions and methods making it hard to make firm conclusions regarding the dietary intake of Brazilian children. The development of tools to evaluate the complexities of dietary intake is much needed. Such a tool needs to be accepted and adopted by numerous study groups, to describe dietary status among Brazilian children and devise the most effective, and to evaluate the success of nutrition education programs.

Changing attitudes, beliefs and feelings towards food in bulimic patients.

Eating attitudes are defined as beliefs, thoughts, feelings and behaviors towards food. Bulimia nervosa (BN) is an eating disorder, in which the eating attitudes are seriously disturbed. Studies that evaluated nutritional aspects of BN focus mainly on food intake, dietary restriction and binge eating, while the follow-up studies evaluate mainly clinical symptoms. The objective of this study was to evaluate eating attitudes of patients with BN, during and after cognitive-behavioral intervention. Thirty nine (39) BN female patients received cognitive behavioral treatment with a multidisciplinary team and had eating attitudes assessed by a questionnaire developed for this research. Frequencies of the attitudes assessed were compared at baseline, after 12 weeks and 24 weeks of treatment. After treatment, patients had less distorted beliefs about food, less guilty after eating "forbidden" foods and they felt more tranquil while eating outside home. Other negative behaviors, as dietary restriction, the desire of not eat, being angry when feeling hungry and using the food to relive stress, persisted. Eating attitudes of patients with BN are hard to be changed in a short-term. More attention to this disease's component and new approaches to treatment are needed in order to have a better recovery.

[Nutritional evaluation and cardiovascular risk in executives submitted to a check-up]. / Avaliação nutricional e risco cardiovascular em executivos submetidos a check-up.

OBJECTIVE: To evaluate the nutritional status and cardiovascular risk among executives. METHODS: In a cross-sectional study. 329 executives of both genders, aged 31 to 70 years, were evaluated during a health check-up in a private hospital in the city of São Paulo. The variables related to weight, height and waist circumference were measured and Body Mass Index - BMI (kg/m(2)) was determined. Blood pressure and serum levels of total cholesterol and fractions, triacylglycerol, glucose and uric acid were analyzed. Physical activity was evaluated by the International Physical Activity Questionnaire (IPAQ) and cardiovascular risk was estimated by the Framingham Scoring. The variance analysis and the Bonferroni methods were used for statistical treatment. RESULTS: The mean age was 44.6 (SD=6.8), with the male gender predominating (89.7%). As for lifestyle, 17% were tobacco smokers and 7.3% sedentary. The mean values found in the clinical and biochemical exams were the following: blood pressure of 117 x 78.6 mmHg (SD=12 x 8.3), total cholesterol of 200.5 mg/dL (SD=35.9), LDL-c of 121.8 mg/dL (SD=29.9), HDL-c of 52.2 mg/dL (SD= 10.9), triacylglycerol of 133.7 mg/dL (SD=76.8), glucose of 96.3 mg/dL (SD=20.5) and uric acid 4.2 and 6.0 mg/dL (SD=1.0 and 0.9) for men and women respectively. The BMI mean for all executives was classified as overweight (26.1 kg/m(2); SD=6.8). Waist circumference was normal in women (79.6 cm; SD=7.3) and indicated a high risk level of chronic disease for the men (96.1cm; SD=8.9). The average Framingham Risk was 5.7%. CONCLUSION: The executives were overweight and presented low cardiovascular risk, according to the Framingham Scoring.

Weight-teasing: does body dissatisfaction mediate weight-control behaviors of Brazilian adolescent girls from low-income communities?

The objective was to examine the mediation hypothesis of body dissatisfaction and analyze their association with weight-teasing and body satisfaction. A total of 253 girls who attended 10 schools from São Paulo, Brazil, participated in this study. Data collection was carried out through a validated and self-reported questionnaire. Study variables were weight-teasing (independent), body satisfaction (mediation), and weight control behavior (outcome). Effect mediation analyses showed a significance level of 5% (p < 0.05). Prevalence of family and peers weight-teasing were 38.5% and 40.6%, respectively. Body dissatisfaction was associated with unhealthy weight control behaviors when controlled by family and peer weight-teasing. Data indicate that family and peers teasing are important aspects that interfere in body satisfaction and weight control behaviors.

Sustained impact of the "Healthy Habits, Healthy Girls - Brazil" school-based randomized controlled trial for adolescents living in low-income communities.

Pediatric obesity is a major public health concern in low- and middle-income countries, such as Brazil. There is an urgent need for preventive programs for adolescents and, the assessment of their sustained impact. This paper reports the longer-term (6-month post intervention) effects of the "H3G-Brazil" obesity prevention program on weight status and weight-related behaviors. A cluster randomized controlled trial starting with 10 public schools in the city of São Paulo, Brazil involved 253 adolescent girls [mean (se) age = 15.6 (0.87) years]. Body mass index (BMI), waist circumference (WC), dietary intake, physical activity (PA) and sedentary behaviors (SB) were assessed at baseline, immediate post-intervention and 6-month post-intervention (follow-up). ANCOVA was performed using intention to treat principles. There was no effect on BMI, the primary outcome. Although, meaningful increases occurred in waist circumference for both groups, the intervention group presented a lower increase (F = 3.31, p = 0.04). This effect size, however, was lower than the criterion for small (d = 0.102). Unfortunately, significant results favored the control group for time spent on TV/weekdays (F = 5.13, p = 0.01), TV/weekends (F = 5.46, p = 0.01) and sedentary behaviors/weekdays (F = 5.32, p = 0.04). No other significant results were found. This obesity prevention intervention among Brazilian adolescent girls did not have the desire effect on BMI. The significantly lower increase in waist circumference in the intervention groups is inconsistent with the adverse changes detected in sedentary time.

Test-retest reliability and discriminant validity of the Restraint Scale translated into Portuguese.

The aim of this study was to evaluate reliability and discriminant validity of the Restraint Scale (RS) translated into Portuguese. The version was obtained through a process of translation and back translation. Women with eating disorders (n = 39: 24 bulimics and 15 anorexics) and students without eating disorders (n = 57) filled the scale. It was hypothesized that if the scale has any discriminant validity, the bulimic scores should differ from those of the students and the anorexics. The questionnaire was applied twice to the controls with 1-month interval to evaluate test-retest stability. Bulimics obtained a score of 28.1 +/- 13 (significantly different from students and anorexics), anorexics obtained 17.3 +/- 9 (significantly different from students), and students 11.3 +/- 5. Body mass index (BMI) was significantly correlated to dietary restraint, especially among controls. Test-retest correlation coefficient was .64 (P = .000001). The RS translated into Portuguese seems to be a valid and reliable instrument, which can be used in many studies of eating behaviors.

Psychometric testing and applications of the Body Attitudes Questionnaire translated into Portuguese.

Although many body attitudes scales have been developed, none have been translated into Portuguese. This study aimed to translate the Ben-Tovim and Walker Body Attitudes Questionnaire and assess validity and reliability for a Brazilian sample. Women with (n = 39) and without (n = 57) eating disorders completed the scale, to assess discriminant validity. Convergent validity was assessed by the correlations between the scores and a measure of body dissatisfaction. The questionnaire was applied twice to controls after 1 mo. to evaluate reliability. Eating-disordered women had significantly higher mean scores on Feeling Fat, Disparagement, Salience and Lower Body Fatness, and lower scores on Attractiveness. No mean difference on Strength and Fitness was found. Most subscales were significantly correlated with the body-dissatisfaction measure. Test-retest coefficients ranged from .57 to .85. The translated version of the Body Attitudes Questionnaire seems to be a valid and reliable measure of body attitudes.

The "Healthy Habits, Healthy Girls" randomized controlled trial for girls: study design, protocol, and baseline results.

The purpose of this article is to describe the study design, protocol, and baseline results of the "Healthy Habits, Healthy Girls" program. The intervention is being evaluated through a randomized controlled trial in 10 public schools in the city of São Paulo, Brazil. Data on the following variables were collected and assessed at baseline and will be reevaluated at 7 and 12 months: body mass index, waist circumference, dietary intake, nutrition, physical activity, social cognitive mediators, physical activity level, sedentary behaviors, self-rated physical status, and overall self-esteem. According to the baseline results, 32.4% and 23.4% of girls were overweight in the intervention and control groups, respectively, and in both groups a higher percentage failed to meet daily recommendations for moderate and vigorous physical activity and maximum screen time (TV, computer, mobile devices). There were no significant differences between the groups for most of the variables, except age (p = 0.000) and waist circumference (p = 0.014). The study showed a gap in the Brazilian literature on protocols for randomized controlled trials to prevent obesity among youth. The current study may thus be an important initial contribution to the field.

[Association of children's consumption of processed foods and family income in the city of São Paulo, Brazil]. / Consumo infantil de alimentos industrializados e renda familiar na cidade de São Paulo.

OBJECTIVE: To describe children's consumption of processed foods and its relationship with per capita family income based on a household survey. METHODS: Food consumption was studied in a statistical sample of 718 children living in the city of São Paulo in the period 1995-1996. A 24-hour dietary recall was used. Data regarding the association of children's consumption of 24 processed foods and per capita family income (arranged in quartiles) was analyzed. RESULTS: Consumption of sugar was higher among children of low income families whereas the consumption of chocolate powder, chocolate, yogurt, infant formula and soft drinks was higher among children of high income families (p< 0.05). CONCLUSIONS: It seems that per capita family income affects the consumption of some processed foods.

[Opinion of women from a family health unit about the quantity of mothermilk produced]. / Opinião de mulheres de uma unidade de saúde da família sobre a quantidade de leite materno produzido.

This is a study aimed at knowing the opinion of women about the quantity of mothermilk produced, since insufficient milk is one of the main reasons mentioned by women from different cultures when introducing complementary feeding in children's diet before the fourth month of life. The interviews were made at the homes of 41 women from a family health unit in the Eastern area of S o Paulo City in 1998 and 1999. The majority of the mothers (82.9%) considered they were producing a sufficient quantity of mothermilk. As evaluation criteria for the produced quantity of mothermilk, they used the size of the breasts, the spontaneous dropping of milk and the mood of the child after breastfeeding. All women introduced artificial milk before the fourth month, but those who mentioned insufficient milk did it earlier (p=0.0088).

[Cross-cultural adaptation and validation of the Health and Taste Attitude Scale (HTAS) in Portuguese]. / Adaptação transcultural e validação para o português da Escala de Atitudes em Relação ao Sabor da Health and Taste Attitude Scale (HTAS).

The scope of this study was to show the cross-cultural adaptation and validation of the Health and Taste Attitude Scale in Portuguese. The methodology included translation of the scale; evaluation of conceptual, operational and item-based equivalence by 14 experts and 51 female undergraduates; semantic equivalence and measurement assessment by 12 bilingual women by the paired t-test, the Pearson correlation coefficient and the coefficient intraclass correlation; internal consistency and test-retest reliability by Cronbach's alpha and intraclass correlation coefficient, respectively, after application on 216 female undergraduates; assessment of discriminant and concurrent validity via the t-test and Spearman's correlation coefficient, respectively, in addition to Confirmatory Factor and Exploratory Factor Analysis. The scale was considered adequate and easily understood by the experts and university students and presented good internal consistency and reliability (µ 0.86, ICC 0.84). The results show that the scale is valid and can be used in studies with women to better understand attitudes related to taste.

Nutritional Status, Lifestyle and Lipid Profile in Vegetarians

Abstract Background: Vegetarian diets have been linked to reduced risk of chronic noncommunicable diseases, since they positively modulate biochemical parameters, particularly those related with glycemic control and lipemia, and considered as potential strategy for weight control. Objective: To compare the nutritional status, lifestyle and lipid profile of adult vegetarians with omnivores in a sample of individuals in the city of São Paulo. Methods: This was a cross-sectional study. Anthropometric, biochemical and lifestyle variables were compared between vegetarians and omnivores. A significance level of 5% was considered for all analyses. Results: Vegetarians were more likely to practice physical activity (64.3% vs 42.5%, p = 0.056) and consuming dietary supplements (48.1% vs 20.5%, p = 0.012). There was no statistically significant difference for the variables: age, sex, triglycerides, total cholesterol and low-density lipoprotein between the two groups. Vegetarians had significantly lower weight [60.8 kg (56.7 - 69.4) vs 71.1 kg (58.0 - 75.4), p = 0.038], BMI [22.4 kg/m2 (20.9 - 23.8) vs 24.6 kg/m2 (21.7 - 26.1), p = 0.001], and waist circumference [(81.8 ± 8.2 vs 87.8 ± 10.9 cm, p = 0.003)], and higher high-density lipoprotein (54.88 ± 14.44 vs 47.30 ± 12.27 mg /dL p = 0.008) than omnivores. Conclusion: Compared with omnivores, vegetarians had a better nutritional status, with lower BMI and waist circumference, significantly higher levels of plasma lipoprotein high-density, and healthier lifestyle.

Teasing and weight-control behaviors in adolescent girls.

OBJECTIVE: To analyze the association between weight teasing, body satisfaction and weight control behaviors. METHODS: Cross-sectional study based on adaptation and validity research of a North American questionnaire for adolescent girls about physical activity, nutrition, body image, perceptions, and behaviors. The variables used to conduct the study were weight control behaviors, body satisfaction and presence of teasing by family members. Descriptive analyses were carried out by chi-square test, being significant p<0.05. RESULTS: A total of 159 adolescent girls, with 16.2±1.3 years old were enrolled in this study. Of the total, 60.1% reported that family members did not tease them. The teasing was associated with weight dissatisfaction (p<0.001), body shape (p=0.006), belly (p=0.001), waist (p=0.001), face (p=0.009), arms (p=0.014) and shoulders (p=0.001). As a consequence, there was association with unhealthy weight control behaviors (p<0.001), vomiting (p=0,011), diet (p=0.002) and use of laxatives (p=0.035). CONCLUSIONS: The teasing about body image by family members was associated with risk for unhealthy weight control behaviors in female adolescents.

Weight-teasing: does body dissatisfaction mediate weight-control behaviors of Brazilian adolescent girls from low-income communities? / Provocações em relação ao peso corporal: a insatisfação com o próprio corpo afeta o comportamento de controle de peso de adolescentes brasileiras de comunidades de baixa renda? / Burlas y acoso por el peso: ¿la insatisfacción corporal afecta al comportamiento para el control del peso en adolescentes brasileñas dentro de comunidades con baja renta?

The objective was to examine the mediation hypothesis of body dissatisfaction and analyze their association with weight-teasing and body satisfaction. A total of 253 girls who attended 10 schools from São Paulo, Brazil, participated in this study. Data collection was carried out through a validated and self-reported questionnaire.

O estudo teve como objetivo examinar a hipótese da mediação pela insatisfação com o próprio corpo e analisar as associações com a provocação por terceiros e com a satisfação com o corpo. A amostra incluiu um total de 253 adolescentes do sexo feminino matriculadas em dez escolas na cidade de São Paulo, Brasil. Os dados foram coletados com um questionário validado e auto-preenchido. As variáveis de estudo foram as provocações feitas por outros em relação ao peso da adolescente (independente), a satisfação com o corpo (de mediação) e o comportamento de controle do peso (desfecho). As análises de mediação mostraram um efeito estatisticamente significativo (p < 0,05). As taxas de prevalência de provocações relacionadas ao peso, feitas por familiares e colegas, foram 38,5% e 40,6%, respectivamente. Depois de ajustar para a provocação por familiares e colegas, a insatisfação com o próprio corpo esteve associada a comportamentos prejudiciais de controle de peso. Os dados indicam que as provocações por familiares e colegas são aspectos importantes que interferem na satisfação com o corpo e com os comportamentos de controle de peso.

El objetivo fue examinar la mediación en la hipótesis de la insatisfacción corporal y analiza su asociación con las burlas y acoso por el peso y la satisfacción corporal. Un total de 253 niñas que iban a diez escuelas de São Paulo, Brasil, participaron en este estudio. La obtención de datos se llevó a cabo mediante un cuestionario validado y autoinformado. Las variables de estudio fueron acoso por peso (independiente), satisfacción corporal (mediación), y control de peso comportamiento (resultado). El efecto de los análisis de mediación mostró un nivel de significancia del 5% (p < 0.05). La prevalencia de la familia y las burlas/acoso por el peso entre compañeras fueron de un 38,5% y un 40,6%, respectivamente. La insatisfacción corporal se asoció con comportamientos poco saludables de control de peso, cuando estuvo controlada por la familia y las burlas y acoso por el peso entre colegas. Los datos indican que la familia y las burlas/acoso entre compañeras son aspectos importantes que interfieren en la satisfacción corporal y comportamientos sobre el control de peso.
