Abstract：Objective To investigate the association between sufficient sleeping, healthy lifestyle and suboptimal health status ( SHS) within the population of Guangdong Province, China.Methods A cross-sectional survey was con-ducted within a clustered sample of 24,159 individuals in Guangdong.Sleep sufficiency was categorically defined by the level of whether sleeping is enough ('never, sometimes, often or always') .Lifestyle was assessed via the health-promo-ting lifestyle scale.SHS was evaluated using the medical examination report and Suboptimal health Measurement Scale V1.0.Results Of the 24,159 participants, the prevalence for the'SHS'and'disease'were 46.0%and 35.2%, respec-tively, higher than that for'healthy'(18.8%).Overall, 4.1 %(986) of participants reported they'never'had sufficient sleeping, with 36.9%(8913) 'sometimes', 44.9%(10847) 'often'and 14.1 % (3413) 'always'.Health status were correlated with whether sleep is enough or not.(χ2 =1 499.945, P=0.000) .After demographic adjustment, regression analyses revealed a significant correlation between sufficient sleeping and healthy lifestyle (P<0.001).Individuals who'never'had sufficient sleeping were 8.391 times more likely to suffer from SHS than individuals who'always'had it ( OR:8.391, 95%CI:6.325-11.131), infrequent sufficient sleeping ('sometimes') with OR 6.049 and CI 5.414-6.758,'often'sufficient sleeping with OR 2.263 and CI 2.058-2.488) ( P=0.000) .Conclusion Sufficient sleeping is signifi-cantly associated with a healthy lifestyle, and appears to be a useful predictor of a healthy lifestyle.Sleep deprivation is re-lated to an increased risk of SHS.
