Health behaviors and illness according to marital status in middle-aged Koreans

Marital status influences health and this association might differ by time and/or country. Divorce rates have increased abruptly in Korea. We investigated relationships between marital status and health behaviors and illness among middle-aged Koreans.

Data from the fifth Korean National Health and Nutrition Examination Survey 2010-12 was used. Participants were middle-aged (40-65 years) Koreans (3015 male and 4498 female) who had been married. Health behaviors and physical and mental health status were evaluated separately for each gender according to marital status (currently married versus separated, divorced or widowed) using logistic regression analyses adjusted for age, income level and region.

About 5.4% of men and 13.0% of women lived without their spouses. Odd ratios (ORs) for smoking, binge drinking, inadequate sleep, hypertriglyceridemia and depression were significantly higher in participants not living with their spouses. ORs for non-participation in regular health examinations and cancer screenings, anemia, elevated alanine aminotransferase and suicidal ideation were significantly higher in men not living with their spouses.

Health behaviors and illness were significantly worse in middle-aged Koreans not living with their spouses. Men were more susceptible to poor health screening, nutritional deficiencies and mental illness. Preventive services are necessary to improve their health status.
