| 目的 了解城乡来源大学新生膳食模式差异, 分析膳食模式与骨密度、体重指数(BMI)的关系.方法 采取分层整群随机抽样方法, 调查1319名17～20岁大学新生膳食模式及其与骨密度、BMI的关系.结果 (1)城乡大学新生在4种膳食模式得分的差异有统计学意义.城市男女生选择“西方食物”型(x2=31.548, P=0.000;x2=13.068, P=0.001)、“动物性食物”型(x2=8.279, P=0.016;x2=41.137, P=0.000)及“钙类食物”型(x2=37.254, P=0.000;x2=15.651, P=0.000)的比例均高于农村, 农村男女生选择“中国传统”型(x2=36.194, P=0.000;x2=25.936, P=0.000)膳食模式比例均高于城市, 差异有统计学意义.(2)来自农村男生的平均身高、体重、BMI、骨密度值均低于城市, 差异有统计学意义(P值均＜0.001);而农村女生仅身高和体重低于城市女生, 差异有统计学意义(P值均＜0.001).(3)农村和城市男女生“西方食物”型膳食模式的因子得分均与BMI值呈正相关(相关系数分别为0.187、0.192、0.551和0.465, P值均＜0.001), “钙类食物”型膳食模式因子得分均与骨密度呈正相关(相关系数分别为0.680、0.342、0.841和0.786, P值均＜0.001), 而“中国传统”型膳食模式的因子得分在农村和城市男生中均与BMI值呈负相关(相关系数为-0.223和-0.093, P＜0.05), 与骨密度呈正相关(相关系数为0.905和0.711, P＜0.001).结论 城乡不同膳食模式对大学新生骨密度、BMI有显著影响. |

| Objective To find out the differences of dietary patterns among freshmen coming from urban and rural areas that might have influenced their bone mineral density and body mass index (BMI).Methods With stratified random sampling method, dietary patterns and their bone mineral density, BMI of 1319 freshmen were studied.Results (1) The ratios of urban freshunen who chose "western food" pattern ( x2=31.548, P=0.000; x2=13.068, P=0.001 ), "animal food" pattern ( x2=8.279, P=0.016; x2=41.137, P=0.000) or "calcium food" pattern (x2=37.254, P=0.000; x2=15.651, P=0.000) were higher than that of rural freshmen, and the ratios of rural freshmen who chose "Chinese traditional" pattern (x2=36.194, P=0.000; x2=25.936, P=0.000) were higher than that of urban freshmen.(2) The average height, weight, BMI, speed of sound (SOS) of male freshmen from rural areas were lower than that from the city and the differences were statistically significant (P＜0.05).Among those female freshmen, only height and weight were significantly different (P＜0.05).(3) In both rural and urban frestunen, the factor scores of "westem food" pattern had a positive correlation with BMI, with the correlation coefficients as 0.187, 0.192, 0.551, 0.465 (P＜0.001).The factor scores of "calcium food" pattern were positively related to bone mineral density (SOS values)with correlation coefficients as 0.680, 0.342, 0.841, 0.786, P＜ 0.001 respectively.The factor scores on "Chinese traditional" pattern were negatively correlated with BMI, with correlation coefficients as -0.223, -0.093 (P＜0.05) which were positively related to bone mineral density (SOS values) in both rural and urban male freshmen, with correlation coefficients as 0.905, 0.711 (P＜0.001).Conclusion Different dietary patterns chosen by urban and rural freshmen had a significant impact on both bone mineral density and BMI. |
