This study aimed to examine the prospective associations between multidimensional sleep behaviours and incident obesity in postmenopausal women, and to explore whether blood biomarkers and plasma metabolites provide exploratory biological evidence.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This prospective cohort study included 68, 419 non-obese postmenopausal women from the UK Biobank. Sleep behaviors (duration, insomnia, chronotype, snoring, daytime sleepiness) were collected via questionnaires. Obesity events were identified using ICD-10 codes. Cox proportional hazards models were used to assess associations, and exploratory indirect-association analyses were performed to evaluate the potential involvement of blood biomarkers and plasma metabolites.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>During a median follow-up of 13.33 years, 1, 146 incident obesity cases were documented. Sleep duration showed an approximately U-shaped association with obesity risk: short sleep (\u22646 hours, HR\u00a0=\u00a01.214) and long sleep (\u226510 hours, HR\u00a0=\u00a01.654) were both associated with increased risk. Frequent insomnia (HR\u00a0=\u00a01.320), evening chronotype (HR\u00a0=\u00a01.224), and snoring (HR\u00a0=\u00a01.234) were also independent risk factors. Exploratory indirect-association analyses suggested small signals involving inflammation- and lipid-related biomarkers, but these findings should be interpreted as hypothesis-generating.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Abnormal sleep duration, frequent insomnia, evening chronotype, and snoring were associated with a higher rate of incident obesity in postmenopausal women.
