工作餐人群血糖和血脂的变化

Blood glucose and lipids levels in populations with workplaceeating habits

目的：研究饮食结构与血糖、血脂的关系及其对健康的影响.方法：我们采用问卷调查和体检资料相结合的方法,选取了每年5月份规律进行体检北京某单位为观察样本单位,随机抽取100例成年受试者作为研究对象,调查研究2000-2004年的有关资料.结果：天冬氨酸氨基转移酶(AST)随着时间延长,有逐年升高趋势；除第5年与第4年比较的差值无显著性外,其余年度间差值均有统计学意义.血糖(GIU)随着时间延长,也有逐年升高趋势；除第3年与第2年和第5年与第4年比较的差值无显著性外,其余年度间差值均有统计学意义.总胆固醇(TCH)随着时间延长,有逐年升高趋势；但除第2年与第1年,第4年与第3年和第5年与第4年比较的差值无显著性外,其余年度间差值均有统计学意义.甘油三脂(TG)随着时间延长,有逐年升高趋势,但除第5年与第1年比较差值有显著性外,其余年度间差值均无统计学意义.结论：该单位职工存在致AST和GIU显著升高的因素,对血浆脂质的升高作用不明显.

AIM： To explore the effect of dietary composition on the levels of blood glucose lipids as well as the health of individuals with workplace-eating habits. METHODS： According to the results of questionnaires and medical examination, 100 adults were randomly recruited from a community of Beijing, in which annual medical examination was regularly performed in May. The related data were collected from 2000 to 2004. RESULTS： The level of aspartate aminotransferase （AST） had a tendency to elevate year by year, and it was significantly different except that between the last two years. Meanwhile, the level of blood glucose tended to increase year by year, and it was markedly different except that between the third and second year as well as that between the last two years. Total cholesterol （TCH） level was enhanced year by year, and it was significant different except that between the second and first year, the fourth and third year as well as that between the fifth and fourth year. Triglycerides （TG） level also had the trend of being elevated year by year, but it had no significant difference except that between the fifth and first year. CONCLUSION： There are some factors that contributes to the elevation of AST and blood glucose levels in the populations with workplace-eating habits, but their contributions for elevating blood lipid level are not obvious.
