北京市区儿童营养状况与血脂谱水平相关性分析

THE RELATION OF NUTRITIONAL STATUS WITH SERUM LIPIDS LEVELS IN BEIJING URBAN CHILDREN

目的 : 了解儿童营养状况与血脂谱水平的相关性。方法 : 对北京市朝阳区 3 1 6名7～ 1 1岁儿童进行血脂谱水平检测、膳食调查及体格检测。结果 : 儿童脂肪供能比为 3 6.2 1 % ,超出标准上限 (2 5 %～ 3 0 % ) ,60 .1 %儿童每日胆固醇摄入量≥ 3 0 0 mg;儿童每日胆固醇摄入量与TC、apo B水平呈正相关 ,糖类供能比与 HDL-C水平正相关 ;高胆固醇摄入组儿童 TC、LDL-C、apoAI水平大于低胆固醇组 ;超重 /肥胖儿童 TC、TG、LDL-C、apo B、Lp(a)水平高于体重正常组及体重不足组 ,并随肥胖程度的增加而增加 ;男童腰臀围比与 TC、TG、LDL-C、apo B水平正相关 ,与HDL-C负相关。结论 : 超重 /肥胖 (尤其向心性肥胖 )、不合理膳食与儿童血脂异常关系密切 。

Objective: To probe into the relation of nutritional status with serum lipids levels in children. Methods: The levels of serum lipids, dietary intakes and physical indices were investigated for 316 children aged 7～11 years in Beijing Chao Yang District. Results: 36.21% of energy was from fat. Of 60.1% children the daily intakes of cholesterol were equal to or more than 300 mg. The intakes of cholesterol were positively associated with TC and apoB levels. Energy percentage from carbohydrate was also positively related with HDL C level. On the other hand, the levels of TC, HDL C and apoAI in cholesterol high intake group were more than control group. The TC, TG, LDL C, apoB and Lp(a) levels in overweight/obese children were more than normal and underweight children, and the lipids levels increased with overweight degree. In boys the waist hip ratios were positively associated with TC, TG, LDL C and apoB levels, negatively with HDL C level. Conclusion: Overweight/obesity (especially abdominal obesity) and unreasonable diet were related closely with dyslipidemia in children. It could be used in early diagnosis for high risk children of dyslipidemia.
