By Tarun Sai LomteJul 14 2023Reviewed by Lily Ramsey, LLM A recent study published in Scientific Reports investigated the associations between sleep quality and health parameters in older adults with obesity.
Sleep impairments are prevalent in older populations. Evidence suggests sleep deprivation can induce a pro-catabolic environment and anabolic resistance. Sleep quality was assessed using the Pittsburgh sleep quality index , which evaluates sleep quality over a month through a questionnaire. Participants were stratified as good and poor sleepers based on PSQI scores; lower PSQI scores reflect good sleep quality.
The Geriatric Anxiety Index and Depression Scale were used to evaluate anxiety and depression, respectively. Findings The study comprised 95 participants, including 46 good and 49 poor sleepers. The mean PSQI of good sleepers was 3.54 compared to 8.86 for poor sleepers. Poor sleepers had lower ALM, ALM-to-BMI ratio, and handgrip strength-to-BMI ratio than good sleepers. Besides, poor sleepers exhibited higher relative fat mass than good sleepers.
These associations were significant even after adjusting for covariates. However, there were no significant associations between sleep quality and handgrip strength.
