Sociodemographic and Health Characteristics Associated with Metabolic Syndrome in Men and Women Aged ≥50 Years.

There are limited studies on the prevalence of and risk factors for metabolic syndrome (MetS) in people aged ≥50 years. This study investigated the sociodemographic and health characteristics related to MetS prevalence in men and women aged ≥50 years to assess clustering of risk factors. This study used the 2016 survey data of 2927 people aged 50-79 years who were administered questionnaires and underwent examinations. Participants were divided into adults aged 50-64 and 65-79 years and further into four subgroups, according to sex. Differences in sociodemographic and health characteristics by sex were verified using the chi-squared test. Complex sample logistic regression analysis was performed to verify factors related to MetS. The sociodemographic characteristics associated with MetS in men and women aged 50-64 years, included living without a spouse, having a middle school education or less, and reporting a low economic status. The health characteristics associated with MetS in men aged 50-64 years were current smoking status and strength training <2 times/week. The sociodemographic characteristic associated with MetS in women aged 65-79 years was living without a spouse. Hypertriglyceridemia was the risk factor most associated with MetS prevalence. Among men and women aged 50-64 years, living without a spouse, having a low education level, and reporting a low economic status were associated with MetS prevalence. Current smoking status and strength training <2 times/week for men and living without a spouse for women aged 65-79 years were associated with MetS.
