ABSTRACT
Resumen En Latinoamérica se han realizado estudios dirigidos a evaluar la insatisfacción corporal y los comportamientos alimentarios anómalos (CAA), sin embargo se han enfocado principalmente en adolescentes o estudiantes universitarios. El objetivo de esta investigación fue evaluar el porcentaje de insatisfacción con el peso corporal (INCP) en una muestra de hombres y mujeres adultos chilenos, analizando la relación de este factor con distintas variables sociodemográficas, psicológicas y conductuales, entre las que figuraron los CAA. Participaron 654 adultos de 18-64 años de edad (436 mujeres, 218 hombres ; con rango de edad de 18-64 años, índice de masa corporal promedio de 25.49 kg/m2), quienes fueron evaluados con base a una batería de cuestionarios de autoreporte. La INCP estuvo presente en 45.9% de la muestra, resultando significativamente mayor en las mujeres que en los varones. Fueron identificadas diferencias significativas en las escalas que evaluaron CAA, en función del índice de masa corporal y el sexo de los participantes, registrando puntuaciones significativamente mayores las mujeres y los participantes con obesidad. Al comparar entre participantes con vs. sin INCP, los primeros mostraron más CAA y menor actividad física. Los resultados de este estudio muestran que la INCP puede interactuar e influir sobre los hábitos alimentarios y la práctica de ejercicio físico.
Abstract The aims of this research were to estimate the percentage of body weight dissatisfaction in males and females Chilean adults, assessing its relationship with different sociodemographic, behavioral and psychological variables, and analyzing whether the presence of body weight dissatisfaction acts as a risk factor for some disordered eating behaviors. The 654 participants (436 women, 218 men; age range 18-64 years, mean body mass index [BMI] 25.49 kg/m2) were evaluated with a battery of self-administered questionnaires. The percentage of body weight dissatisfaction in the whole sample was 45.9% and significantly higher in women than men. Significant differences were observed in the clinical scales that evaluated disordered eating in function of the BMI of the participants; in those scales females also showed higher scores than males. Comparing participants with and without body weight dissatisfaction, the first one showed more unhealthy eating behaviors. The results of this study show how body weight dissatisfaction can interact and influence healthy habits, such as a daily eating behaviors and physical exercise.
ABSTRACT
This study was undertaken to explain weight control behavior and intention of obese children and adolescents as measured by the elements of the health belief model. A total of 732 obese students from 28 schools in Seoul metropolitan area and their mothers were assessed with a self-administered questionnaire. The analyzed results are as follows; l. Among obese students, 45.3% of male students and 57.2% of female students, a significantly higher portion than male students, reported that they had tried to lose weight within the recent year. Exercise was the most frequently used method to lose weight followed by diet control, drug use, and specialized clinic visits, in descending order. 2. Male students were more likely to try to lose weight if they perceived a low threat level and their mother had a job, and female students were more likely to try to lose weight if they were younger in age, perceived a low threat level and had strong external motivating factors. 3. Female students showed a significantly higher level of intention to obesity control than male students, and the intention level of their mothers also showed the same trend. 4. In male students, the degree of weight dissatisfaction, weight control experience, the level of obesity related beliefs of students, the educational level of the mother and economic status of the family were significant predictors of intention to obesity control, and in females, age, the level of obesity related beliefs of students and intention of their mothers were significant. In the mothers of male students, obesity index of students, age of the mother and the level of obesity related beliefs of the mother were significant predictors of intention of the mother, and in the mothers of female students, obesity index of students, occupational status of the mother and obesity related beliefs of the mother were significant. 5. According to the path model of intention to obesity control, the degree of weight dissatisfaction had the most powerful effect in male students, and perceived net benefit level was the most important variable in female students. Since the weight control behavior and intention of obese students were more predictable by the degree of weight dissatisfaction than the obesity index, we can conclude that only the students dissatisfied with their weight are well motivated for obesity control. There can be a discrepancy between the mother and her child's beliefs and intention status(especially in male students), so the therapists should also assess the student's opinion as well as the mother's. In female students, the perceived net benefit level was the most important predictor of intention to obesity control, therefore the intervention program should pay particular attention to the positive benefits of weight control rather than negative aspects(threats) of obesity.
