Obesity is one of the major health problems in the world as well as in Islamic republic of Iran. The present study was performed to investigate the overweight and obesity and its related factors in adult women referred to medical and health centers in Shiraz.
In this cross-sectional study using multi-stage random sampling, 240 women aged 18-65 years old who referred to health centers were selected, in 2013-2014. Height, weight, waist and hip circumferences were measured and BMI and WHR were calculated. The questionnaire of demographic factors, physical activity and food frequency were completed. Data were analyzed by SPSS software using Spearman and Chi-square tests and logistic regression modeling. Statistical differences were considered significant at P<0.05.
The prevalence of overweight and obesity based on BMI was 29.2% and 13.8%, respectively. The mean of W/H ratio was 0.89±0.06 cm and based on this index79.2% of the subjects had visceral obesity. There were a direct correlation between BMI and age, number of children, labor, energy and fat intake and also an inverse correlation between BMI and physical activity, age of marriage and protein intake(P <0.05). No meaningful correlation was found between BMI and marital status, occupation, education level, income level, metropolitan area, smoking and history of parental obesity. Based on logistic regression modeling, menopause, high energy intake and low physical activity were determinant factors of overweight and obesity (P <0.05).
Finding the determinant factors of obesity can make it easy to focus on prevention programs and effective interventions to control this health concern in the population.
