This is the authors' abstract. We don't add key points for this paper.

Background : The older adults are increasing and depression is commonly observed within this community. This study is one of the first that assessed depression and its risk factors in a healthy well-nourished over-55 years old population. Method : Beck Depression Inventory-13 (BDI-13) was used to determine depression in 766 individuals. a full report of socioeconomic factors was gathered. Lifestyle and physical activity were assessed using Health Survey Questionnaire 36-Item Short-Form and International Physical Activity Questionnaire, respectively. The dietary nutrient intake was recorded using an adjusted dietary recall analyzed using the USDA Food Ingredients Database. Result : The prevalence of depression was 31.5% (62.5±6.6 years old). One hundred and thirty-two (17.2%), 93 (12.1%), and 19 (2.5%) individuals had mild, moderate, or severe depression. Males, higher age, not working, higher education, inactivity, living alone, lower-income, divorced, and widows had a higher odd-ratio (OR) of depression. lifestyle shows a 1% higher quality of life score in any component can have 3.8-1.1% significantly lower OR of depression. Trance fatty acids, starch, iron, and copper that are generally increased during oil reheating showed a higher OR for having depression. The correlation of quality of lifestyle components with the severity of depression (BDI-13 score) was the strongest and negative while the weakest correlation was for nutrients with BDI-13 score. Conclusion : The risk of depression in healthy populations is high. Active lifestyle and healthy diet with the presence of family can reduce OR of depression in elderly populations. Food processes can be more important than diet.
