J-shaped relationship between physical activity and frailty risk in adults with sleep disorders: the additional protective role of the weekend warrior pattern
Randomized trial demonstrates reduced frailty risk in adults with sleep disorders through physical activity, suggesting significant implications for health.
Key Points
The research aimed to explore the relationship between physical activity and frailty risk in adults with sleep disorders.
Examined data from 2,706 participants with sleep disorders from the National Health and Nutrition Examination Survey (2007–2018).
Physical activity was measured using the Global Physical Activity Questionnaire and expressed as metabolic equivalent minutes per week.
Utilized multivariable logistic regression and nonlinear modeling for analysis.
Identified a J-shaped association between physical activity and frailty, with lower odds of frailty (OR = 0.50, 95% CI: 0.33–0.76) below 1,037 MET-min/week.
Participants in the highest physical activity quartile showed lower odds of frailty compared to the lowest quartile (OR = 0.65, 95% CI: 0.46–0.91).
The 'weekend warrior' pattern was associated with lower odds of frailty (OR = 0.49, 95% CI: 0.25–0.96).
