There are few studies and inconsistent findings on the role of sleep-related parameters in the development of metabolic syndrome (MetS) among youths. In this study, we aim to investigate the relationship between sleep-related parameters and MetS among youths in a large sample size in Rafsanjan, a region in the southeast of Iran.
The current cross-sectional study was performed on 3,006 young adults aged 15-35, who registered for Rafsanjan Youth Cohort Study (RYCS), as part of Rafsanjan Cohort Study (RCS)). In fact, RCS is a branch of the prospective epidemiological research studies in Iran (PERSIAN). In the present study, we included 2,867 youths after excluding some subjects with missing information on MetS components. MetS was diagnosed based on Adult Treatment Panel III (ATP III) criteria. Besides, data on sleep-related parameters were collected by self-report questionnaires.
The overall prevalence of MetS was 7.74% among the participants. In addition, bedtime, wake time, napping, night shift work, and sleep duration per night and day had no association with the higher odds of having MetS. In contrast, long sleep duration at night was associated with the lower odds of high waist circumference (WC) (OR: 0.82,95% CI :0.67-0.99).
In the present study, long sleep duration at night was associated with lower odds of central obesity. However, more longitudinal studies with the objective measurement of sleep-related parameters are needed to verify the associations reported in the current study.
关于睡眠相关参数在青少年代谢综合征（MetS）发生发展中的作用，研究较少且结果不一致。在本研究中，我们旨在调查伊朗东南部拉夫桑贾地区大量青少年样本中睡眠相关参数与MetS之间的关系。
本横断面研究对3006名年龄在15 - 35岁的年轻成年人进行，他们注册参加了拉夫桑贾青年队列研究（RYCS），这是拉夫桑贾队列研究（RCS）的一部分。实际上，RCS是伊朗前瞻性流行病学研究（PERSIAN）的一个分支。在本研究中，我们排除了一些在MetS组成部分信息缺失的受试者后，纳入了2867名青少年。MetS根据成人治疗小组III（ATP III）标准进行诊断。此外，通过自我报告问卷收集睡眠相关参数的数据。
参与者中MetS的总体患病率为7.74%。此外，就寝时间、起床时间、午睡、夜班工作以及每晚和白天的睡眠时间与患MetS的较高几率无关。相比之下，夜间长时间睡眠与高腰围（WC）的较低几率相关（OR：0.82，95%CI：0.67 - 0.99）。
在本研究中，夜间长时间睡眠与中心性肥胖的较低几率相关。然而，需要更多通过客观测量睡眠相关参数的纵向研究来验证本研究报告的关联。
