Who is Free from Hypertension, Diabetes and Dyslipidemia in the Middle-aged and Elderly Population of Japan? : Verification through a Longitudinal Survey of Middle-aged and Elderly People (Japanese)

(Background and Methods) For this study, we called hypertension, dyslipidemia, and diabetes mild lifestyle-related diseases (MLD), and examined which people are more (less) likely to be diagnosed with MLD among the middle-aged and elderly people of Japan, focusing on lifestyle factors. Data from 11 years of the Longitudinal Survey of Middle-Aged and Older Adults by the Japanese Ministry of Health, Labor and Welfare were used for the analyses. A complementary log-log model was chosen for the analyses. (Results) For men, those who drink alcohol are more likely to be diagnosed with MLD. Former smokers are more likely to be diagnosed with MLD than current smokers. Men who perform light exercise four days or more per week or those who perform vigorous exercise one through three days per week are less likely to be diagnosed with MDL than non–exercisers. Men who monitor their food intake and brush teeth after meals are less likely to be diagnosed with MLD. For women, those who drink alcohol are less likely to be diagnosed with MLD. Former smokers are more likely to be diagnosed with MLD than current smokers. Women who perform medium exercise four days or more per week are more likely to be diagnosed with MLD than non–exercisers. Women who monitor their food intake or take vitamin or mineral supplements are more likely to be diagnosed with MLD. Women who eat a variety of foods and maintain appropriate body weight level are less likely to be diagnosed with MLD. (Reservation) Some of these results are inconsistent with previous studies, are contrary to current understanding, or are not well known. Hence, further studies with greater focus on causal relationships are required.
