To understand the adverse association of short sleep duration and insufficient fruit and vegetable intake (FVI) with and their combined effect on metabolic syndrome (MetS) in Chinese adults.This cross-sectional study analyzed 7052 adults aged 18∼64 years old in 2009, with fasting blood samples collected. Participants were divided into short/normal/long sleep duration groups and sufficient/insufficient FVI groups in accordance with self-reported information. Metabolic syndrome was defined by National Cholesterol Education Program's Adult Treatment Panel III criteria.The prevalence of MetS among the study subjects was 21.74%. Participants were classified into short (<7 h/d), normal (7∼9 h/d), and long (>9 h/d) groups according to their daily sleep duration. Participants with less than 500 g of FVI per day was considered as insufficient FVI. After adjusting for confounders, the negative effect of short sleep duration on MetS was statistically significant, with an OR of 1.29 (95%CI = 1.06∼1.56); and high fasting glucose levels were significantly associated with insufficient FVI. Compared with subjects with normal sleep duration and sufficient FVI, participants with short sleep time and insufficient FVI had the highest risk of MetS (OR = 1.37, 95% CI: 1.04-1.66).This study revealed that insufficient FVI and short sleep duration were significantly associated with an increased risk of MetS among Chinese adults. Increasing FVI and normal sleep duration during Chinese adults could be significant targets for reducing the prevalence of MetS.
为了了解中国成年人中睡眠不足和水果、蔬菜摄入量不足（FVI）的不良关联及其对代谢综合征（MetS）的影响以及两者的综合影响。本横断面研究分析了 2009 年年龄在 18-64 岁的 7052 名成年人，采集了空腹血样。参与者根据自我报告的信息分为短/正常/长睡眠时间组和充足/不足 FVI 组。代谢综合征按照国家胆固醇教育计划成人治疗专家组 III 标准定义。研究对象中代谢综合征的患病率为 21.74%。根据每日睡眠时间，参与者被分为短（<7 小时/天）、正常（7-9 小时/天）和长（>9 小时/天）组。每天 FVI 摄入量低于 500 克被认为是 FVI 不足。在调整混杂因素后，短睡眠持续时间对 MetS 的负面影响具有统计学意义，OR 为 1.29（95%CI=1.06-1.56）；空腹血糖升高与 FVI 不足显著相关。与正常睡眠时间和充足 FVI 的受试者相比，睡眠时间短和 FVI 不足的受试者患 MetS 的风险最高（OR=1.37，95%CI：1.04-1.66）。本研究表明，在中国成年人中，FVI 不足和短睡眠持续时间与 MetS 风险增加显著相关。增加中国成年人的 FVI 和正常睡眠时间可能是降低 MetS 患病率的重要目标。
