以健康食堂为载体的营养健康促进模式的干预效果评价

目的 评价以健康食堂为载体的营养健康促进模式的干预效果,为向其他单位食堂推广应用提供科学依据.方法 于2012年选择江苏省常州市1所创建健康食堂大学的429名教职工为干预组,另1所未采取任何干预措施的947名大学教职工为对照组,此外,干预组进一步按是否经常在食堂就餐分为经常食堂就餐组（≥2次/周）和偶尔食堂就餐组（＜2次/周）;分别在干预前、后（1年）测定血压、体质指数（BMI）,检查脂肪肝发生情况,测定血清中的葡萄糖、总胆固醇、三酰甘油、尿酸、低密度脂蛋白胆固醇、高密度脂蛋白胆固醇;分别进行干预组和对照组间干预前后的对比,并进一步进行干预后干预组中经常食堂就餐组和偶尔食堂就餐组间的对比分析以评价其干预效果.结果干预组干预后的血糖（5.06±0.62） mmol/L、血尿酸（310.57±71.79） μmol/L、血总胆固醇（4.88 ±0.86） mmol/L、血三酰甘油（1.39±0.67）mmol/L及血低密度脂蛋白胆固醇（2.51 ±0.62） mmol/L均显著低于干预前,血高密度脂蛋白胆固醇（1.43 ±0.34） mmol/L显著高于干预前,差异均有统计学意义（t=7.513、2.126、2.062、3.731、8.891、-2.309,P＜0.05）;而对照组干预后的血糖和血尿酸均显著高于干预前,差异有统计学意义（t=-3.491、-7.703,P＜0.01）,血总胆固醇、血三酰甘油、血高密度脂蛋白胆固醇及血低密度脂蛋白胆固醇干预前后差异均无统计学意义（P＞0.05）.干预组干预后的血糖、血尿酸、血总胆固醇、血三酰甘油、血低密度脂蛋白胆固醇、BMI的异常率及高血压发生率均显著低于干预前,差异均有统计学意义（x2=4.202、3.940、4.031、7.305、59.422、4.273、7.385,P＜0.05）;而对照组除干预后血尿酸异常率和脂肪肝发生率均显著高于干预前,差异有统计学意义（x2=23.740、7.408,P＜0.05）外,干预后的血糖、血总胆固醇、血三酰甘油、血低密?

Efficacy evaluation of healthy canteen based-nutritional health promotion

Objective To evaluate efficacy of healthy canteen based-nutritional health promotion so as to provide evidence for popularization and application.Methods A total of 429 college professors and administrative staffs with a healthy canteen were selected as the intervention group in 2012 in Changzhou,and another 947 counterparts without a healthy canteen were selected as the control group.Those of the intervention group was further assigned to the ≥2 times/week and〈2 times/week subgroups.Blood pressure,fatty liver,serum triglycerides,blood glucose,total cholesterol,uric acid,low-density lipoprotein cholesterol,high-density lipoprotein cholesterol and body mass index（BMI）were tested before and after the intervention.Results After the intervention,the mean serum glucose（5.06±0.62）mmol/L],uric acid（310.57 ± 71.79）μmol/L],total cholesterol（4.88 ± 0.86）mmol/L],triglycerides（1.39 ± 0.67）mmol/L]and low-density lipoprotein cholesterol（2.51 ±0.62）mmol/L]of the intervention group were significantly decreased（t values were 7.513,2.126,2.062,3.731 and 8.891,respectively; all P〈0.05）,and mean high-density lipoprotein cholesterol（1.43±0.34）mmol/L]were significantly increased（t=-2.309,P〈0.05）.After the intervention,mean serum glucose and uric acid of the control group were significantly increased（t values were-3.491 and-7.703,respectively; both P〈0.05）,although there was no statistically significant difference of mean serum triglycerides,total cholesterol,low-density lipoprotein cholesterol and high-density lipoprotein cholesterol in the control group before and after the intervention（all P〉0.05）.The abnormality rates of serum glucose,uric acid,total cholesterol,triglycerides,low-density lipoprotein cholesterol and BMI as well as the incidence of hypertension of the intervention group were significantly decreased after the intervention（x2 values were 4.202,3.940,4.031,7.305,59.422,4.273 and 7.385,respectively; P〈0.05）.In the control group,although the abnorm
