To analyze the relationship between low to moderate physical activity and the prevalence of metabolic syndrome (MS).
A multi-stage stratified cluster sampling was conducted in 31 provinces, autonomous regions, and municipalities in the interior of China according to the program of the National Nutrition and Health Survey in 2002. Questionnaire survey, interview, physical examination, measurement of biochemical indices and dietary investigation were done. In total, the physical activity of 26 477 persons aged 18 or above were investigated. The duration of low to moderate physical activity was divided into five grades: 0-min/week, 90-min/week, 151-min/week, 301-min/week, over 420 min/week, and the MS prevalence were investigated respectively. The relationship between MS and age (including four age groups 18-, 35-, 45-, 60 or above) or the duration of physical time were investigated.
The MS prevalence among persons aged 18 or above was 9.4% (2490/26 477). And the prevalence was 10.3% (1191/11 516) in man and 8.7%(1299/14 961) in women, respectively (χ(2) = 21.035, P = 0.000). The MS prevalence was 2.1% (127/6070) in 18-years old group and 15.0% (1012/6734) in over 60 years old group. The MS prevalence increased with increasing age (χ(2) = 776.768, P = 0.000). 81.2% (21 499/26 477) of subjects engaged in low to moderate intensity physical activity. The percentage of spending time on physical activity over 420 min/week was dominant and as high as 43.7% (11 561/26 477). The MS prevalence was 13.8% (166/1203) for 0-min grade, 13.2% (64/485) for 90-min grade, 11.8% (153/1298) for 151-min grade, 10.1% (124/1225) for 301-min grade and 12.5% (512/4090) for over 420 min grade (χ(2) = 9.58, P = 0.047). Logistic regression analysis results showed, the MS risk of subjects spending 301-min per week on low to moderate intensity physical activity was significantly low than the MS prevalence among subjects of 90-min grade, OR = 0.844 (95%CI: 0.675 - 0.968), and no statistical difference was found in people spending over 420 min per week OR = 0.936(95%CI: 0.769 - 1.136).
Most of people aged 18 or above engaged in low to moderate intensity physical activity. MS prevalence may be decreased by low to moderate intensity physical activity for 301-min per week, but the decrease was not significant while the duration of time was longer than 420 min per week.
分析低至中等强度体力活动与代谢综合征（MS）患病率之间的关系。
按照2002年全国营养与健康调查方案，在中国内地31个省、自治区、直辖市进行多阶段分层整群抽样。开展问卷调查、访谈、体格检查、生化指标检测及膳食调查。共调查了26477名18岁及以上人群的体力活动情况。将低至中等强度体力活动时长分为五个等级：0分钟/周、90分钟/周、151分钟/周、301分钟/周、超过420分钟/周，并分别调查MS患病率。研究MS与年龄（包括18 -、35 -、45 -、60岁及以上四个年龄组）或体力活动时长之间的关系。
18岁及以上人群的MS患病率为9.4%（2490/26477）。男性患病率为10.3%（1191/11516），女性患病率为8.7%（1299/14961），差异有统计学意义（χ(2)=21.035，P = 0.000）。18岁组的MS患病率为2.1%（127/6070），60岁及以上组为15.0%（1012/6734）。MS患病率随年龄增长而升高（χ(2)=776.768，P = 0.000）。81.2%（21499/26477）的研究对象进行低至中等强度体力活动。每周体力活动时长超过420分钟的比例最高，达43.7%（11561/26477）。0分钟等级的MS患病率为13.8%（166/1203），90分钟等级为13.2%（64/485），151分钟等级为11.8%（153/1298），301分钟等级为10.1%（124/1225），超过420分钟等级为12.5%（512/4090）（χ(2)=9.58，P = 0.047）。Logistic回归分析结果显示，每周进行301分钟低至中等强度体力活动的研究对象患MS的风险显著低于90分钟等级的研究对象，OR = 0.844（95%CI：0.675 - 0.968），每周体力活动时长超过420分钟的人群与90分钟等级人群相比差异无统计学意义，OR = 0.936（95%CI：0.769 - 1.136）。
大多数18岁及以上人群进行低至中等强度体力活动。每周进行301分钟低至中等强度体力活动可能会降低MS患病率，但每周时长超过420分钟时，患病率降低不显著。
