With regard to metabolic syndrome-related risks (MS risks), obese workers have been the focus of attention, and less attention has been paid to non-obese subjects as if they were free from the risks. The present analysis was initiated to know if no-obesity means no-MS risks. Participants of the study were 804 male workers, who showed no pathological findings in 12 MS-related and other health parameters in 2003, and had complete sets of data in 2008. They were classified by BMI in 2003 into lean (< 18.5), normal (> or = 18.5 to < 25) and obese groups (> or =25). Proportion of MS in 2008 was examined by use of the second phase of MS criteria. Proportions for the lean, normal and obese subjects who met MS criteria in 2008 were 3.2, 4.8 and 5.3%, respectively, with no significant difference in proportions among them. In the non-obese (i.e., lean+normal) group, age was not significantly influential to increase BMI. Thus, the MS risk exists even in non-obese young workers. Anti-MS effort should be directed not only to obese but to non-obese workers, and care should be extended irrespective of ages.
关于代谢综合征相关风险（MS 风险），肥胖工人一直是关注的焦点，而对于非肥胖人群的关注较少，似乎他们没有面临这些风险。本分析旨在了解是否不肥胖就意味着没有 MS 风险。本研究的参与者是 804 名男性工人，他们在 2003 年的 12 项与 MS 相关的健康参数中没有病理发现，并且在 2008 年有完整的数据。他们在 2003 年根据 BMI 分为瘦（<18.5）、正常（≥18.5 至<25）和肥胖组（≥25）。使用 MS 标准的第二阶段检查 2008 年 MS 的比例。2008 年符合 MS 标准的瘦、正常和肥胖受试者的比例分别为 3.2%、4.8%和 5.3%，它们之间的比例没有显著差异。在非肥胖者（即瘦+正常）组中，年龄对 BMI 的增加没有显著影响。因此，MS 风险即使在非肥胖的年轻工人中也存在。抗 MS 工作不仅应针对肥胖者，还应针对非肥胖者，而且无论年龄大小，都应给予关注。
