Relationship between delivery history and health-related quality of life in menopausal South Korean women: The Korea National Health and Nutrition Examination Surveys

Objectives: The study investigated the association between childbirth history and health-related quality of life (QOL) in menopausal South Korean women. Study design: Cross-sectional analysis of data from the 2010-2012 Korean National Health and Nutrition Examination Surveys (KNHANES) for 4277 menopausal women aged over 50. We used the EuroQol index to measure health-related QOL. Main outcome measures: The relationship between delivery history and health-related QOL in menopausal South Korean women was analyzed. Results: After adjustment for age (model 1), women who were younger at their first delivery and who had a greater number of deliveries had a significantly higher risk of problems with mobility, self-care, usual activities and pain or discomfort; the risk of anxiety or depression was not increased. After adjustment for age, BMI, smoking, use of alcohol, exercise, income, education, marital status, metabolic syndrome and stress (model 2), women who were younger at their first delivery and who had a greater number of deliveries had a significantly higher risk of problems with mobility, self-care and pain or discomfort. Age at last delivery was not significantly associated with health-related QOL in either model. Conclusions: South Korean women who were younger at their first delivery and who had more deliveries appear to be at increased risk of health-related QOL problems after menopause.
