ABSTRACT
In 21[st] century obesity has rapidly increased and it has become one of the greatest public health problems worldwide. The aim of this study was to determine related factors with obesity in Tehranian households. In this descriptive study, multivariate analysis was used to estimate the odds of obesity [BMI >/= 30 kg/m2] as a function of age, sex, marital status, educational level and smoking by using data from" Tehran Lipid and Glucose Study [TLGS]" database. In this study 3,935 households participants who were equal or more than 20 years old, were recruited from phase III [2006-2008] of this study. Height of participants was measured to the nearest 5 mm without considering their shoe heels. Weight and height were measured using digital electric scale and meter tape. Data were analyzed by SPSS/16 and SAS version 9.1. The mean BMI was 26.59 [kg/m[2]] in men and 27.96 [kg/m[2]] in women. After adjustment for other variables, obesity odds ratios were 1.01 [P<0.001], 2.10 [P<0.001], and 1.54 [P<0.001] for age, women and married individuals, respectively. There was an inverse significant association between education and obesity. Obesity ORS were 0.83 [P<0.028] for high school and 0.50 [P<0.001] for university educational levels. The results of this study show that related factors in this research are similar to other countries. Therefore, obesity with related factors should be considered in health programming
