彰武县中学生血脂水平及异常分布特征调查

Investigation on blood fat level and abnormity distribution trait in middle school students of Zhangwu country of Liaoning province

目的了解高血压及心脑血管疾病高发区中学生血脂水平及异常情况,以便采取干预措施。方法在彰武县农村随机抽取6所中学,对抽取的全部学生进行调查并测定血清胆固醇(TC)、甘油三酯(TG)、低密度脂蛋白胆固醇(LDL-C)、高密度脂蛋白胆固醇(HDL-C)及体格检查。结果(1)调查学生TC为(3.52±0.65)mmol/L,TG为(0.94±0.53)mmol/L,LDL-C为(1.71±0.49)mmol/L,HDL-C为(1.32±0.41)mmol/L。TC、TG和LDL-C女生均高于男生,差异有统计学意义。(2)各年龄组之间血脂呈交替高低变化。(3)肥胖组TC、TG水平均高于体重正常组,HDL-C水平则是肥胖组低于体重正常组,差异有统计学意义。(4)女生TC、TG和LDL-C的异常率略高于男生,而HDL-C异常率发生水平则男生略高于女生。(5)4种指标在不同年龄组中异常率的发生无随年龄增高而增高的趋势。(6)TG异常情况在肥胖组高于体重正常组,差异有统计学意义。结论该地区青少年空腹血TC、TG、LDL-C和HDL-C水平低于全国大部分地区城市健康青少年水平。

Objective To know the abnormal situation of high school students blood lipid in the area where cardiovascular disease incidence rate was above normal level so that intervention measurement could be adopted. Methods Six high school were selected randomly in ZhangWu courty of Liaoning province and physical examinations were carried to every objects, then limosis blood and isolated serum were collected to test choleterim （TC）, triglyceride（TG）, low density lipoproteln cholesterin and high density lipoprotein cholesterin. Results （ 1 ） The TC level of all the students was （3.52 ± 0.65） mmol/ L, the TG level was （0.94 ± 0.53 ） mmol/L, the LDL - C level was （ 1.71 ± 0.49） retool/L. The HDL - C level was （ 1.32±0.41） mmol/L, the TC, TG and LDL- C level of boy students was higher than that of girl students significantly. However, the HDL- C level of boy students was a little higher than that of girl students. （2）The blood lipids level changed alternatively. （3） The TC, TG level of overweight group was higher than that of normal weight group. The HDL - C level of overweight group was lower than that of normal weight group significantly. （4） The TC, TG and LDL - C abnormal rate of girl students was higher than that of boy students. However, the situation of HDL- C was adverse. （5） The abnormal rate of the four index among age groups had no the trench that it increased with age. （6） The TG abnormal rate of overweight was higher than that of body normal weight group significant. Conclusion The blood fat level of the area students is lower than that of most places in the country. The cardiovascular disease incidence of the adolescents who live in rural area of china is higher than other areas and their blood fat level rule may be different.
