Background: The effects of population aging are becoming apparent throughout the world. Diseases, such as cardio-vascular disease (CVD) and diabetes, are among the most important factors affecting morbidity and mortality, especially in the elderly. These diseases not only result in huge economic costs for treatment and care, but also results in hardship and time lost for relatives of the afflicted individuals. The association between nutritional status and disease is well known. In the present study, the effects of both under-nutrition and over-nutrition on the prevalence of disease are monitored in an urban Iranian elderly population. Thus far, no similar study has been performed in the Iran. Methods: This cross-sectional study was conducted in Isfahan, Iran, during late 2003 on 1694 elderly people (731 males, 963 females), aged 60 years and older. Subjects were randomly chosen from all urban elderly people during a door-to-door and weight and height survey. They were selected using a cluster sampling method, each containing 30 clusters. From each cluster, 58 elderly were selected at random. Using each subjects body mass index (BMI), the nutritional status was categorized as overweight (BMI greater than 25), underweight (BMI less than 19) and normal (having a BMI equal to or more than 19 and equal to or less than 25). Any illnesses known to each subject were also recorded. Results: Results showed that 4.7% of the subjects were underweight and 61.2% overweight. Women were more likely to be overweight and long periods of watching television increased the risk of overweight in all subjects. Being overweight was associated with diabetes and coronary vascular diseases, and lean people were less likely to suffer from such diseases. Conclusion: This study indicates a high prevalence of overweight among the Iranian elderly population, indicating the need for improvement in nutritional status in order to reduce the prevalence of diabetes and CVD.
