Study On The Relationship Between Sleep Duration And Metabolic Syndrome Among Urban Workers In Guangzhou

BackgroundThe prevalence of metabolic syndrome is increasing annually and has become a serious global public health problem,closely associated with chronic kidney disease and cardiovascular disease.The prevalence of metabolic syndrome is also high in China,and identifying risk factors are essential for the prevention of metabolic syndrome.Recent evidence from epidemiological studies suggests that the length of sleep may increase the risk of metabolic syndrome.This study will use data from Guangzhou to explore the relationship between sleep duration and metabolic syndrome,in hope that it may provide relevant recommendations for the prevention and treatment of metabolic syndrome.PurposeThis study will use the health examination data of urban workers in Guangzhou to describe the distribution of nap duration,nighttime duration and prevalence of metabolic syndrome,and to investigate the relationship between the variation of nap duration/nighttime sleep duration and metabolic syndrome in different strata of Guangzhou urban workers.MethodThe prevalence of metabolic syndrome and sleep duration of the participants were obtained by questionnaires and health examination data.For counting data,the study was described using the composition ratio(%),and comparisons between groups were made using Chi-square analysis;for measurement data,comparisons between groups were made using ANOVA if the data obeyed a normal distribution and met Chi-square,or non-parametric tests if the conditions were not met.The relationship between nap duration/nighttime sleep duration and metabolic syndrome by gender stratification was analyzed by multi-factor logistic regression.ResultsA total of 4185 study subjects were included in this study,2570 males and 1615 females with a mean age of(37.21±8.58)years.A total of 661 people were detected with metabolic syndrome,with an overall prevalence of 15.79%,of which 485 were detected in male,with a prevalence of 18.87%,and 176 in female,with a prevalence of 10.90%.The results of the study showed that in the total sample population,longer nap duration(≥30 min)was associated with a higher risk of MS;both subgroups of 3090 min and ≥90 min nap sleep duration increased the risk of MS in both male and female.Nighttime sleep duration in the<5h and ≥9h subgroups were associated with a higher risk of MS;nighttime sleep duration in the<5h and ≥9h subgroups were associated with a higher risk of MS in male,and only nighttime sleep duration ≥9h was observed to be associated with a higher risk of MS in female.ConclusionsThe overall prevalence of MS in the urban worker population in Guangzhou was 15.79%,with a higher prevalence in male than in female(18.87%vs.10.90%).Longer nap duration(≥30 min)was associated with higher risk of MS,and nighttime sleep duration in both<5 h and ≥9 h subgroups was associated with higher risk of MS in male,while only nighttime sleep duration ≥9 h was observed to be associated with higher risk of MS in female.
