This study identifies novel associations of longer sleep duration and more consolidated sleep with more favorable leptin and adiponectin patterns, suggesting a potential biological pathway through which sleep influences metabolic health during aging. The moderating effects of sex and central obesity on sleep-adiponectin associations highlight the importance of considering individual metabolic context when evaluating the impact of sleep on metabolic health. Together, these findings advance the understanding of the links between sleep and adipokine regulation in older adults.<\/jats:p>\n
