In older adults (50+) in low-income settings, severe sleep problems are strongly and independently correlated with greater physical disability and feelings of depression/anxiety, rather than just socioeconomic status.
If you are over 50 and struggling with sleep, do not assume it is just due to being poor or old. The strongest predictors of severe sleep problems are physical disability and mental health struggles like depression or anxiety. Addressing these underlying health issues may be more effective than focusing solely on environmental factors or wealth.
limited physical functionality or greater disability and feelings of depression and anxiety were consistently strong, independent correlates of sleep problems, in both women and men, across the 8 sites (P < 0.001).
Why this rating
Large sample size (n=43,935), multi-center, rigorous multivariate adjustment, but cross-sectional design limits causal inference.
