P1555Metabolic syndrome severity score is a predictor of worse diastolic function independently of each individual metabolic syndrome component: a community-based cohort study

Abstract Background A variety of health problems, such as metabolic syndrome (MetS), have been linked to sleep disorders. While numerous epidemiological studies have shown a U-shaped relationship between sleep duration and poor health outcomes, the results were limited and inconsistent. This study was designed to evaluate the relationship between sleep duration and MetS. Methods This population-based study was conducted on the participants aged 35–70 of Bandare-Kong Non-Communicable Diseases (BKNCD) Cohort Study, a part of Prospective Epidemiological Research Studies in IrAN (PERSIAN). MetS was diagnosed according to the National Cholesterol Education Program (NCEP) criteria and the Iranian-specific cut-off for waist circumference (≥ 95 cm). Sleep information was extracted through a standard questionnaire based on self-reported information. Data were analyzed by R software using generalized additive models (GAMs). A statistically significant level was considered as P < 0.05. Results A total of 3695 participants were included in the analyses. The mean age was 48.05 years (SD 9.36), and 2067 (55.9%) were female. The estimated Prevalence of MetS was 35.9%, and women appeared to be more likely to have MetS than men (P < 0.001). There was a non-linear and linear association between sleep duration and the risk of MetS in women and men, respectively. The lowest risk was observed among those with 7–7.5 h of sleep duration per night. Conclusion Long sleep duration was associated with increased risk of MetS and higher MetS severity score in both genders, while the short sleep duration increased the risk of Mets as well as MetS severity score just in women. The longitudinal studies would be suggested to assess the relationship between sleep quality and quantity components and MetS.

Abstract Background: There is increasing trend of metabolic syndrome (MetS) in rural areas of China in recent years. It is necessary to figure out the possible risk factors of MetS for better intervention. This community-based prospective cohort study was performed to assess the relationship between snoring status and incidence of MetS.Methods: We conducted a cohort study among residents aged ≥ 35 years without MetS in 2012-2013. Among 5,691 residents who met the inclusion criteria, 4,980 residents (2,586 men and 2394 women; follow-up proportion: 87.5%) remained available for follow-up examinations during 2015-2017. The main outcome was the incidence of MetS, defined by the unify criteria in 2009. We divided residents by snoring status and compared outcome between groups. Using a logistic regression model, we estimated the odds ratio (OR) for incidence for MetS, adjusting for confounders, ages, gender, exercise habit, sleep duration, alcohol and smoke consumption. Results: With a median follow up of 4.6 years, incidence of MetS was higher in snorers (men 26.2%, women 33.5%) than in non-snorers (men 19.7%, women 23.2%). Diastolic blood pressure increased in follow-up compared with baseline in male snorers but decreased in male non-snorers. Similarly, fast blood glucose level increased in female snorers at follow-up but decreased in female non-snorers. We found a significant association between snoring and incidence of MetS (adjusted OR=1.51, 95%CI=1.32-1.74). Besides, as the degrees of the snoring increased, the incidence of MetS increased simultaneously. And the OR for the very severe snoring was double compared with non-snorers (adjusted OR=2.10, 95%CI=1.38-3.20). Conclusion: Snoring is associated with higher incidence of MetS in rural Northeast Chinese. More emphasis should be paid to residents with snoring problem.
