目的了解中山市高中学生的血生化水平。方法整群随机抽取中山市四所学校的学生进行血生化水平检测、分析。结果血清胆固醇(TC)、低密度脂蛋白胆固醇(LDL-C)和高密度脂蛋白胆固醇(HDL-C)水平女生均显著高于男生(P<0.01),TC和LDL-C的异常率女生显著高于男生(P<0.01),LDL-C水平城区显著高于镇区(P<0.01);女生空腹血糖水平显著低于男生(P<0.01);男生的贫血率显著低于女生(P<0.05),镇区学生的贫血率显著低于城区学生(P<0.05);血红蛋白(Hb)与心血管疾病的危险因素LDL-C和TC呈负相关关系(P<0.05),与心血管疾病的保护因素HDL-C呈正相关关系(P<0.05)。结论加强对女生和城区学生营养知识宣传教育,改变不良饮食习惯,降低贫血的发生以及成年后心血管疾病发生危险性。
Objective To understand the blood biochemical level of high school students in Zhongshan City. Methods The cluster was randomly selected from four schools in Zhongshan City for blood biochemical detection and analysis. Results The levels of serum TC, LDL-C and HDL-C in girls were significantly higher than those in boys (P <0.01). The abnormal rates of TC and LDL-C in girls (P <0.01). The level of LDL-C in urban area was significantly higher than that in town area (P <0.01). The fasting blood glucose level of female students was significantly lower than that of male students (P <0.01) (P <0.05). There was a negative correlation between hemoglobin (Hb) and cardiovascular risk factors LDL-C and TC (P <0.05) HDL-C, a protective factor of the disease, was positively correlated (P <0.05). Conclusion Strengthen the propaganda and education on nutritional knowledge of girls and urban students, change bad eating habits, reduce the occurrence of anemia and the risk of cardiovascular disease in adulthood.
