The Effect of Body Mass Index, Smoking and Alcohol Consumption on Successful aging with the mediating role of Quality of Life in the Elderly with type2 Diabetes

The aim of this study was to investigate the effect of body mass index, smoking and alcohol consumption on successful aging mediated by quality of life in the elderly with type 2 diabetes. The research method is cross-sectional correlation. The statistical population of this study consisted of all elderly people aged 60 years and older with type 2 diabetes covered by health centers in Shiraz in 1398, from which 593 people were selected by available sampling method in two stages. In this study, the tools of brief cognitive status test (Fulstein et al., 1975), physical function questionnaire (Bartel, 1965), and for successful aging, social welfare questionnaire (Keys, 2004), spiritual health questionnaire (Polutzon and Allison, 1982). Life satisfaction (Diner, 1985) and quality of life questionnaire (Thomas, 1986) were used, all of which had acceptable validity and reliability. SPSS-V23 and PLS software were used to analyze the data. Structural equation modeling was also used to answer the research hypotheses. Findings showed that the model was confirmed by model fit at the intermediate level. The results also showed that no significant relationship was observed between the variables of body mass index, smoking and alcohol consumption and successful aging mediated by quality of life. Therefore, paying attention to the mentioned variables in prevention and designing more appropriate treatments will help researchers and therapists in the elderly with diabetes. Subsequent results of the study showed that there is an inverse and insignificant relationship between alcohol consumption in the elderly with type 2 diabetes and successful aging with mediated quality of life. Among the problems of different countries, especially developing countries, is the association of the phenomenon of population transition with epidemiological transition. In this way, at the same time as passing from a young population with high fertility and death to a population with low fertility and death, by implementing a program to fight infectious diseases and promote education and health, the pattern of community diseases in favor of chronic diseases such as diabetes Has changed.
