Abstract: Background: Obesity has been called the disease of the twenty-first century. There are more than 1 billion overweight people (BMI≥25) in the world. Of those, approximately 350 million are obese (BMI ≥30.0) .The prevalence of obesity is also increasing in older populations throughout the world. The prevalence of obesity among elderly people in industrialized countries estimates suggest ranging from 15% to over 30%. In Iran, as of 2008, 6.3% of the population is obese. Overweight was more among women (39.5%) than men (24.5%) The prevalence of obesity is also increasing in older populations throughout the world. Method: This study is a cross sectional study. Participants included 2200 women and 2180 men aged 50-75 years. The logistic regression was applied to model the relationship between the odds of obesity and age, gender marital status, educational level, alcohol consumption and smoking. Results: Obesity odds ratios were 2.16 (95% CI: 1.71-2.72) for women, 0.68 (95% CI: 0.47-0.97) for smokers and 1.96 (95% CI: 1.53-2.52) for the subjects with alcohol consumption. Regarding the people aged 50-55 years as the reference group, the obesity odds ratios were 0.86 (95% CI: 0.66-1.10) for ages 56-60 years, 0.75 (95% CI: 0.57-0.97) for ages 61-65 years, 0.43 (95% CI: 0.30-0.60) for ages 66-70 years and 0.36 (95% CI: 0.20-0.63) for ages 71-75 years. Using the High school degree or below as the reference group of education level, obesity odds ratios were 1.38 (95% CI: 1.08-1.76) for the diploma level and 0.92 (95% CI: 0.56-1.52) for the B.Sc ad B.A degree and higher level group. Conclusion: Using High school degree or below as the reference group of educational level, Obesity odds ratios for the diploma level, and B.Sc ad B.A degree and higher level groups were 1.38 and 0.93, respectively. The findings show that in Iran people gain weight up to age of around 50-60 years old and after that BMI tends to decrease. Our results on the association between age and obesity. In our study, obesity was strongly associated with alcohol consumption. Compared to non consumer elderly subjects, consumer elderly subjects were twice as likely to be obese. The environment can influence access to healthy food, lifestyle behaviors such as the trend toward 'eating out', lack of sidewalks and accessible recreation areas. To avoid strong declines in the quality of life due to population ageing, and to ensure sustainability of the health care system, reductions in the burden of disability among elderly populations are urgently needed.Therefore, a community-based multiple strategies are required to combat with increasing rate of obesity and its subsequent complications such as diabetes hypertension and cardiovascular disease, osteoarthritis.
