上海市区1997～1999年部分新生儿及体检人群血脂水平调查

目的 分析90年代末期在上海居民生活水平提高情况下的血脂值，并与70-80年代作的调查进行比较，了解不同年龄段居民平均血脂水平的变化。方法 采集1997年至1999年上海市工厂，机关，企、事业单位，学校等职工和学生健康体检血样以及新生儿脐带血共3647名，测定血脂项目包括总胆固醇（TC）、甘油三酯（TG）、低密度脂蛋白（LDL-C）、高密度脂蛋白（HDL-C）水平，从新生儿至70岁以上按10岁为一年龄组，男、女性分别进行统计学分析。结果 （1）血脂水平胡年龄增径而增高，TC和LDL-C50岁以后女性高于男性，TG50岁以后女性接近男性，HDL-C则各年龄组女性均高于男性；（2）90年代与70年代相比TC和TG水平明显升高，分别增了6.79%-17.69%和21.95%-45.53%，而HDL-C则明显下降了8.05%-29.19%；（3）40岁以上人群TC和TG水平超过正常上限者90年代（TC男11.57%、女16.02%，TG男4.40%,女5.40%)较70年代（TC男4.40%、女5.40%，TGL国5.20%、女5.70%)明显增多；（4）40岁以上组比40岁以下组TG/HDL-C≥4，同时TG≥1.70mmol/L的有明显升高（男20.74%比10.99%，女13.32%比2.06%)。结论 随着居民生活水平的提高，平均血脂水平有上升趋势，必须十分注意饮食结构的合理安排。

A survey on blood lipid levels among newborns and healthy inhabitants in urban Shanghai fron 1997 to 1999

OBJECTIVE: To analyze the blood lipid levels among inhabitants of different ages in urban Shanghai by the end of 1990 and compare the results with those in 1970 s and 1980 s. METHODS: Venous blood samples were collected from 3647 persons undergoing annual health examination, including workers and staff members, employees, functionaries, and students of factories, governmental organizations, institutions, enterprises, and schools. Umbilical blood samples were collected from 88 newborns. Serum TC, TG, LDL-C, and HDL-C were determined. RESULTS: 3647 blood samples were collected in total. It is found that: (1) The levels of blood lipids increased along with the age. The levels of TC and LDL-C among females over their fifty were higher that those among the males in the same age groups. The level of TG among females over fifty was similar to that among the males in the same age groups. The levels of LDL-C were higher in families in all of the age groups than those in the males of the same ages. (2) In comparison to those in 1970 s the levels of TC and TG in 1990 s were significantly higher by 6.79% - 17.69% and 21.95% - 45.53% respectively, and the level of HDL-C decreased by 8.02% - 29.19%. (3) The percentage of persons over forty with their TC levels over the upper normal limit was much larger in 1990 s than in 1970 s (for TC 11.57% vs. 4.40% among males and 16.02% vs. 5.40% among females, for TG 21.83% vs. 5.20% among males and 13.32% vs. 5.70% among females). and (4) The percentage of persons with their TC/HDL-C >or= 4 and TG >or= 1.70 mmol/L was much larger among persons over forty than among persons under forty (20.74% vs. 10.99% among males and 13.32% vs. 2.05% among females). CONCLUSION: The mean serum TC, TG, and LDL-C levels increased and the HDL-C level decreased significantly among healthy inhabitants in urban Shanghai in 1990 s. Along with the rise of living standards of people, their mean lipid level increases too. Nutrition education is necessary.
