ABSTRACT: Objective.Â The objective of this study was to investigate the association between self-reportedÂ sleepÂ durationÂ and the incidence of features of themetabolicÂ syndromeÂ inÂ adults.Â Methods.Â A longitudinal analysis from the Quebec Family Study (Canada) was conducted on 293 participants, aged 18 to 65years, followed for a mean of 6years (until 2001). Participants were categorized asÂ shortÂ (â‰¤6h), adequate (7-8h) or long (â‰Ą9h) sleepers. TheÂ metabolicÂ syndromeÂ was defined according to the American Heart Association/National Heart, Lung, and Blood Institute’s criteria. The hypertriglyceridemic waist phenotype was defined as high waist circumference (â‰Ą90cm in men and â‰Ą85cm in women) combined with high fasting triglyceride level (â‰Ą2.0mmol/L in men and â‰Ą1.5mmol/L in women).Â Results.Â The incidence rates ofÂ metabolicÂ syndromeÂ and hypertriglyceridemic waist phenotype were 9.9% and 7.5%, respectively.Â ShortÂ sleepers were significantly more atÂ riskÂ of developing theÂ metabolicÂ syndromeÂ (relativeÂ riskÂ (RR): 1.74; 95% confidence interval (CI): 1.05-2.72) and the hypertriglyceridemic waist phenotype (RR: 1.82; 95% CI: 1.16-2.79), compared to those sleeping 7 to 8h per night after adjusting for covariates. However, longÂ sleepÂ durationÂ was not associated with an increasedÂ riskÂ of developing theÂ metabolicÂ syndromeÂ or the hypertriglyceridemic waist phenotype (either unadjusted or adjusted models).Â Conclusion.Â ShortÂ sleepÂ durationÂ is associated with an increasedÂ riskÂ of developing features of theÂ metabolicÂ syndromeÂ inÂ adults.
