Weight Control in Postmenopausal Korean Patients with Osteo-arthritis.

Background: Weight control is crucial for osteoarthritis management. This study investigated weight control methods in postmenopausal Korean osteoarthritis patients and examined their correlation with subjective health status and figure recognition, obesity, quality of life (QoL), and hemodynamic variables.

Methods: One thousand six hundred and seventy-eight female postmenopausal osteoarthritis patients participated in the 2018 Korea National Health and Nutrition Examination Survey. A frequency analysis was conducted for weight control methods, and phi coefficients for crossover analyses or Cramer's V coefficient were calculated to identify the relationships between weight-control-related variables and subjective health status and QoL. Using independent -tests, we examined the relationships of weight control methods with hemodynamic variables.

Results: Postmenopausal osteoarthritis patients' preferred weight control methods were exercise, meal volume reduction, functional diet consumption, and the skipping of meals. Osteoarthritis patients who performed exercise demonstrated improved subjective figure recognition and health status, body weight, and recent 2-week discomfort, QoL, and hemodynamic variables (systolic blood pressure and fasting glucose, hemoglobin A1C, total cholesterol, high-density lipoprotein cholesterol, and high-sensitivity C-reactive protein [hs-CRP] levels). However, patients who attempted weight control by food volume reduction made relatively harder efforts to lose weight but were more likely to view themselves as obese, and demonstrated higher pain levels, anxiety/depression, and recent 2-week discomfort. Further, they exhibited lower triglyceride levels, as did patients who skipped meals.

Conclusion: Overall, Korean postmenopausal osteoarthritis patients' preferred weight control methods were exercise and reduced food intake. Although reduced food intake was effective for weight control, exercise improved mental health and hemodynamics, particularly inflammation (hs-CRP) levels.
