目的了解青少年肥胖类型与代谢综合征(MS)及其组分的相关性,为有效预防儿童青少年肥胖及相关疾病提供依据。方法选取2009年延边地区安图县汉族高中毕业生1 095名,全部测量身高、体重、腰围及血压。以人体质量指数(BMI)和腰围身高比值(WHtR)作为不同类型肥胖指标,测定空腹血清三酰甘油、高密度脂蛋白胆固醇及血糖。结果超重肥胖组的腹型肥胖、高血压、高血糖及MS检出率高于正常组(P值均<0.01),腹型肥胖组的超重及肥胖、高血压、高血糖、高TG及MS检出率高于正常组(P值均<0.05)。超重肥胖合并腹型肥胖组的高血压、高血糖及MS患病危险性高于任何单一类型肥胖组,腹型肥胖组的高血压、高血糖、高TG和MS患病危险性高于超重肥胖组。结论超重肥胖合并腹型肥胖显著增加高血压、高血糖及MS的患病危险,腹型肥胖组的高血压、高血糖、高TG和MS患病危险高于超重及肥胖。联合应用BMI与WHtR可提高对MS及其组分的预测效应。
Objective To understand the correlation between obesity types and metabolic syndrome (MS) and their components in adolescents and provide basis for preventing obesity and related diseases in children and adolescents effectively. Methods A total of 1 095 Han Chinese high school graduates from Antu County, Yanbian Prefecture in 2009 were selected to measure height, weight, waist circumference and blood pressure. Fasting serum triglyceride, high density lipoprotein cholesterol and blood glucose were measured by using body mass index (BMI) and waist circumference ratio (WHtR) as indicators of different types of obesity. Results Abdominal obesity, hypertension, hyperglycemia and MS in overweight and obesity group were higher than those in normal group (all P <0.01). Overweight and obesity, hypertension, hyperglycemia, high TG and MS in abdominal obesity group The detection rate was higher than the normal group (P <0.05). Hypertension, hyperglycemia and MS risk of overweight and obesity with abdominal obesity group were higher than those of any single type of obesity group. The risk of hypertension, hyperglycemia, high TG and MS in abdominal obesity group was higher than that of overweight and obesity group. Conclusion Overweight obesity combined with abdominal obesity significantly increased the risk of hypertension, hyperglycemia and MS. The risk of hypertension, hyperglycemia, high TG and MS in abdominal obesity group were higher than those in overweight and obesity. The combination of BMI and WHtR improves the predictive power of MS and its components.
