INTRODUCTION
Little is known on how the domain and intensity of physical activity (PA) associates with metabolic syndrome (MetS). The aim of this study was to examine associations between PA domains (leisure-time, domestic, active transport, total walking and total PA), PA intensities (light, moderate and vigorous) and PA levels with MetS in the general adult population.
METHODS
Cross-sectional study. Anthropometry, blood biochemistry, 79-item PA-questionnaire, lifestyle and medical history were evaluated in a representative sample of Canary Island adults (n = 6,729). MetS was diagnosed using the harmonized IDF-NHLBI-AHA criteria. T-test and multivariable logistic regression was used to analyse associations between PA domains and intensities with MetS vs. no MetS, controlling for socio-demographic, lifestyle, family antecedents and body mass index (BMI).
RESULTS
For each MET-h/day spent in moderate-vigorous PA intensities, as well as in recreational domain, active transport, total walking and total PA, the odds of MetS decreased between 3-10%. Energy expenditure exclusively in light and domestic PAs was not associated with MetS, however it was important to achieve a total PA level of 3 MET-h/day, which reduced the odds of MetS by 23%. This reduction was blunted in those with more than 2 h/d of TV watching time. A PA level of 3 MET-h/d also nullified the risk of MetS in those with low PA and high TV consumption.
CONCLUSIONS
Some types of leisure time PAs may contribute more than others to reducing MetS. Light and domestic PA play a complementary role in enhancing energy expenditure in the general population. TV watching time above 2 h/d counteracted the MetS risk reduction associated with PA level, but PA level also reduced the risk of METs presented by those with a low level of PA and an excess TV watching time. Physical activity explains a greater amount of the variance of MetS than any other factors of lifestyle, education, sex and family history, and substantially mitigates the strong association of age and BMI with MetS.
简介
关于体力活动（PA）的领域和强度如何与代谢综合征（MetS）相关，目前知之甚少。本研究旨在探讨一般成年人群中 PA 领域（休闲时间、家务、主动交通、总步行和总 PA）、PA 强度（低强度、中强度和高强度）和 PA 水平与 MetS 之间的关系。
方法
横断面研究。在加那利群岛成年人的代表性样本中评估了人体测量学、血液生化、79 项 PA 问卷、生活方式和病史。使用协调的 IDF-NHLBI-AHA 标准诊断 MetS。使用 t 检验和多变量逻辑回归分析 PA 领域和强度与 MetS 与无 MetS 之间的关系，同时控制了社会人口统计学、生活方式、家族史和体重指数（BMI）。
结果
对于中等至高强度 PA 强度和娱乐领域、主动交通、总步行和总 PA 每消耗 1 个代谢当量/小时，MetS 的几率降低 3-10%。仅进行低强度和家务 PA 的能量消耗与 MetS 无关，但达到 3 个代谢当量/小时的总 PA 水平可将 MetS 的几率降低 23%。对于每天观看电视时间超过 2 小时的人，这种降低作用减弱。3 个代谢当量/天的 PA 水平也可消除低 PA 和高电视消费人群中 MetS 的风险。
结论
某些类型的休闲时间 PA 可能比其他类型的 PA 更有助于降低 MetS。低强度和家务 PA 在增强普通人群的能量消耗方面发挥着互补作用。每天观看电视时间超过 2 小时会抵消与 PA 水平相关的 MetS 风险降低，但 PA 水平也降低了低 PA 和高电视观看时间人群中 MetS 的风险。PA 比生活方式、教育、性别和家族史的任何其他因素更能解释 MetS 的更大变异，并且大大减轻了年龄和 BMI 与 MetS 之间的强关联。
