【摘要】 目的　了解浙江省不同人群膳食营养现状 ,分析膳食营养与血压的相关性。方法　在农村、城市、城镇 2 5～ 74岁自然人群中随机整群抽取 4841人进行高血压危险因素调查的基础上 ,按 1 0∶ 1抽取 496人进行连续三天2 4小时膳食调查 ,对其中资料完整的 470人进行显著性、相关性统计学分析。结果　 (1 )人群每日平均摄入各种营养素及能量热比与 RDA推荐量相比均有显著性差异 (P<0 .0 0 1 )。 (2 )居民膳食食物中碳水化合物 89.9%为米及米制品 ,粗粮谷类仅为 0 .2 % ,肉食类、鱼虾类均超过 RDA推荐量 ,以城市人群及 2 5～ 2 9岁青年组为明显 ;奶制品摄入仅为 RDA推荐量的 8.69% ,以农村人群更明显。 (3 )收缩压水平与脂肪、蛋白质、碳水化合物、钠摄入量相关 (P均 <0 .0 0 1 ) ;舒张压水平与脂肪摄入量相关 (P<0 .0 0 1 )。 (4 )高血压与正常血压人群蛋白质、脂肪、碳水化合物的摄入热比有显著性差异 (P<0 .0 0 1 ) ;视黄醇、硫胺素、尼克酸的摄入量两组人群中有显著性差异 (P<0 .0 5 ) ,高血压与正常血压人群摄入钠 /钾比值分别为 1 .2 9、 1 .3 ,无显著性差异。结论　 (1 )浙江省城乡居民膳食营养摄入存在低蛋白质、高脂肪、高碳水化合物的不合理现状 ,同时存在 B族维生素、钙明显摄入不足 ,钠摄入过多的现?更多还原

【Abstract】 Objective In order to study the nutritional survey on diet and its relation to blood pressure in Zhejiang.Methods A survey was carried out in Zhejiang.496 subjects aged 25～74 years old were selected by a random stratified multilevel cluster sampling.The diet was assessed by food weighing plus consecutive individual 3 days food records.Results the diet of urban people were richer in fat and had higher quality protein compared with the diet of rural people.Low intakes of Vitamin B,calcium,potassium,and protein were found in both areas.The sodium intake was very high in both areas.Mean intakes of fat,carbohydrate,and sodium were significant positively correlated with blood pressure(p<0.001).Mean intake of protein and Vitamin A were significant negatively associated with blood pressure(p<0.001).The quantity of heat ratio of fat,protein and carbohydrate from diet in hypertension were higher than these in normal blood pressure(p<0.001).Conclusions There is a unreasonable nutritional intabe in Zhejiang.It is particular in rural preople and young people.Intake of nutritions is significant associated with blood pressure.The quantity of heat ratio of diet is one of the important facts on blood pressure.更多还原
