AB - This study aimed to identify latent classes of health-related quality of life (HRQoL) among middle-aged women in South Korea and examine the characteristics and predictive factors of each class.
This was a descriptive study using secondary data from the 8th-9th Korea National Health and Nutrition Examination Survey (2021, 2023), including 1,073 women aged 40-49 years. Latent class analysis using the Korean Health-related Quality of Life Instrument (HINT-8) identified three distinct classes: Health-vulnerable group (31.2%), Intermediate group (45.7%), and Health-favorable group (23.1%).
Approximately 76.9% of participants experienced difficulties in HRQoL. Multinomial logistic regression revealed that household income, family size, pregnancy experience, subjective health perception, physical activity, chronic diseases, stress, and depression were significant predictors. Psychological and socioeconomic factors consistently influenced all group comparisons. The findings provide foundational data for developing tailored interventions to improve HRQoL among middle-aged women.
