Weekly Walking Attenuates the Association Between Frailty and Depressive Symptoms in Patients With Rheumatoid...

Area of Science:

• Rheumatology
• Gerontology
• Psychiatry

Background:

• Rheumatoid arthritis (RA) patients face increased risks of physical and psychological decline.
• Frailty and depressive symptoms are common comorbidities in RA, impacting quality of life.
• Understanding factors that mitigate these risks is crucial for RA patient care.

Purpose of the Study:

• To investigate if weekly walking moderates the association between frailty and depressive symptoms in adults with RA.
• To identify the threshold of walking frequency that influences the frailty-depression relationship.

Main Methods:

• Cross-sectional observational study using data from the Korea National Health and Nutrition Examination Surveys (2016, 2018).
• Included 206 adults aged 45+ diagnosed with RA.
• Survey-weighted multivariable linear regression and Johnson-Neyman technique were used to analyze moderating effects.

Main Results:

• Frailty significantly predicted depressive symptoms in RA patients.
• A significant interaction between frailty and walking frequency was observed (β = -3.68, p = 0.010), indicating a buffering effect of walking.
• The positive association between frailty and depressive symptoms was present when individuals walked less than approximately 3.5 days per week.

Conclusions:

• Regular engagement in weekly walking attenuates the relationship between frailty and depressive symptoms in RA patients.
• Promoting even low levels of physical activity, like walking, is important for mental health in frail RA individuals.
• Findings suggest walking interventions could help reduce depression risk in this population, though causal interpretation is limited by study design.
