determinants of weight loss and obesity control behaviors among women based on the pender’s health promotion model

Background: lifestyle changes, advertising, and access to high-calorie, low-value foods have led to an increase in the prevalence of obesity and overweight, and women are at greater risk in this regard. the aim of the present study was to identify the determinants of weight loss and obesity control behaviors based on pender’s health promotion model (hpm) among women referring to the healthcare centers of shahrekord, iran. methods: this descriptive-analytical study was performed on 500 women aged 18-49 years with a body mass index (bmi) ≥ 25 in 2019. the cluster sampling method was performed on the healthcare centers, and women were selected using simple random sampling. the data collection instrument included a researcher-made questionnaire, the reliability and validity of which were approved, and finally, data were analyzed using analytical tests in spss 22 and stata14. results: the mean (± standard deviation) of the women’s age was 34.33 ± 8.2 years. a total of 57.8% of women had no history of weight loss and obesity control behaviors. variables such as age, education level, and marital status were statistically significantly related to weight loss and obesity control behaviors (p ≤ 0.05). moreover, the constructs of prior related behaviors, interpersonal influences, and commitment to a plan of action were among the predictors of weight loss and obesity control behaviors and predicted 6.6% of behavioral changes (r2: 6.6, p < 0.05). conclusion: overall, prior related behaviors, interpersonal influences, and commitment to a plan of action are predictors of weight loss and obesity control behaviors, and thus it is suggested to place more on these constructs while designing relevant health-promotion interventions.
