The prevalence of weight-control behaviors and associated factors among adolescent girls in Tehran.

Weight control behavior is a strategy for weight loss or weight gains that range from healthy to unhealthy. This study is aimed to determine the prevalence of weight control behaviors and their related factors in adolescent girls in Tehran. Adolescent girls in the last grade of high school (n=491) that were selected by a multi-stage sampling method completed a cross-sectional survey (2018) in Tehran city in Iran. Data were collected using questionnaires (standard and researcher-made) by the self-report method and analyzed using descriptive and inferential statistics, including Chi-square, independent t-test, and logistic regression. 17.5% of adolescents had healthy, 60.6% had unhealthy, 15.8% had extreme unhealthy weight control behaviors, and 6.1% had no weight control behaviors. 74.8% of adolescents were in the normal body mass index (BMI) percentile. Unhealthy weight control behaviors were observed more than healthy behaviors at all BMI levels. Weight control behaviors had significant relationships with weight control intention (p=0.005), family (p=0.016) and peers (p=0.011) encouragement to weight control, engagement of relatives in weight control behaviors (p=0.016), anxiety (p<0.001), and age (p=0.030). BMI has a positive correlation with body weight satisfaction (p<0.001) and body weight perception (p<0.001). The results of logistic regression showed that increasing anxiety score can increase the possibility of engaging in unhealthy weight control behaviors (odd ratio=1.086, p=0.006). Considering that a significant percentage of adolescents have unhealthy and extreme unhealthy weight control behaviors, and some of these behaviors leave irreversible effects on the health of this age group, design, and implementation of educational programs to prevent such behaviors seem imperative. © 2020 Walter de Gruyter GmbH, Berlin/Boston.
