目的了解合肥市大学新生的骨密度现状,并分析膳食模式与其骨密度的关系。方法采用分层整群随机抽样的方法抽取1414名大学新生,最终收集到有效问卷1319份。检测人群的超声骨密度值。采用因子分析法判断大学新生的膳食模式,采用协方差分析,控制混杂因素后,比较不同膳食模式组间的骨SOS修正均数。结果 (1)4种膳食模式较为有意义:"西方食物"型(摄入较多的汉堡包及油炸食品、腌制食品、坚果类、零食、可乐、雪碧、咖啡、糖类);"动物性食物"型(摄入较多的猪肉、羊肉、牛肉、禽肉、动物肝脏、鱼虾类、海带/海鱼/紫菜等海制品、坚果类);"钙类食物"型(摄入较多新鲜水果、鸡蛋、鱼虾类、海带/海鱼/紫菜等海制品、奶及奶制品、豆类及豆制品、坚果类);"传统中国"型(摄入较多的粮谷类、新鲜蔬菜、新鲜水果、猪肉)。(2)高"动物性食物"型膳食模式的骨密度(SOS值)低于低"动物性食物"型(P<0.05);高"钙类食物"型膳食模式的骨密度(SOS值)高于低"钙类食物"型(P<0.05);高"传统中国"型膳食模式的骨密度(SOS值)高于低"传统中国"型膳食模式(P<0.05)。结论合肥市大学新生的膳食模式和骨密度关系密切。
Abstract：Objective In order to investigate the bone density of freshmen,and to analyze the association between dietary pattern and bone mineral density(BMD).Methods A questionnaire survey on the situation of dietary pattern was conducted in 1414 freshmen.Effective dietary survey questionnaires and bone mineral density measurements were completed for 1319 participants.Bone mass was assessed by using an Ultrasound Bone Densitometer on the right calcaneus(CM-200,Furuno Electric Corporation,Japan),and the speed of sound(SOS,m/s) was used as an indicator for bone density.Factor analysis with varimax rotation was used to identify the dietary patterns.After adjusting for confounders,covariance with Bonferroni's was used to further examine the associations between dietary patterns and bone mineral density(BMD).Results(1)Four major dietary patterns were noticed.Western food pattern(high consumption in hamburger,fried food,nuts,biscuit,chocolate,cola,coffee,sugars).Animal protein pattern(high consumption in pork,mutton,beef,poultry meat,animal liver).Calcium pattern(high consumption in fresh fruits,eggs,fish and shrimps,kelp laver and sea fish,milk and dairy products,beans and bean products).Traditional Chinese pattern(high consumption in rice and grain,fresh fruits,fresh vegetables,pork).(2) No association was observed between the western food pattern and bone mineral density.High animal protein pattern showed lower SOS value compared with low animal protein pattern.High calcium pattern showed higher SOS value compared with low calcium pattern.High traditional Chinese pattern showed higher SOS value compared with the low traditional Chinese pattern.Conclusion Dietary patterns are closely related with bone mineral density(BMD) of freshmen.
