Factors Influencing Quality of Life in Late Adulthood with Hypertension, Diabetes, Dyslipidemia, or Obesity: Using the Complex Sample Design of the Korea National Health and Nutrition Examination Survey (KNHANES)

Key Points

• This research aims to identify multidimensional factors affecting the quality of life (QOL) in older adults with chronic conditions.
• Utilized data from the 2022 Korea National Health and Nutrition Examination Survey (KNHANES)
• Focused on adults aged 65 and older with hypertension, diabetes, dyslipidemia, or obesity
• Applied complex sample design with weights, stratification, and clustering
• Conducted descriptive statistics and complex sample multiple regression analysis.
• Average QOL score among subjects was 0.87
• Significant factors included symptoms (depression and anxiety), functional status (grip strength), overall health (subjective health perception), personal characteristics (BMI), and household income
• These variables accounted for 34.0% of the total explanatory power of QOL.
• Lower levels of depression and anxiety, a BMI below obesity, higher grip strength, and better subjective health perception were associated with higher QOL.
