摘要
目的:探讨辽宁省不同性别、地区、年龄和收入水平居民的奶类摄入状况及变化。方法:利用2002年和2012年中国居民营养与健康监测资料,分析不同年份辽宁省居民饮奶率、饮奶量及奶类所提供钙的变化。结果:辽宁省居民饮奶率为22.5%,城市是农村的7倍(35.8%VS 5.1%),女性高于男性,不同年龄组和收入水平均有显著性差异(P<0.05)。平均每日奶类摄入量为34.10±81.4g/d,城市是农村9.6倍(55.8±99.1g/d VS 5.8±32.0g/d),高收入组是低收入组的2倍(53.4±85.7g/d VS 26.2±70.8g/d);饮奶者饮奶量平均为151.9±107.8g/d,其中农村饮奶者奶类摄入量最低,为114.6±89.2g/d;60岁以上年龄组最高,为160.9±116.1g/d。同2002年相比,居民饮奶率增长了21.6%(18.5%VS 22.5%)。其中农村和低收入组增长幅度较大,饮奶率分别增加了1.7倍(1.9%VS 5.1%)和1.1倍(8.7%VS 18.0%);平均每日奶类摄入量基本持平,农村奶类摄入量虽然增加了近1倍(5.8±32.0g/d VS 2.9±23.9g/d),但仍处于最低水平。居民膳食钙平均每日摄入量为357.3±207.6mg/d,饮奶者钙的摄入量为非饮奶者1.6倍(506.8±224.1mg/d VS 313.9±180.8mg/d),不同性别、年龄、地区和收入水平中饮奶者钙的摄入量是非饮奶者1.5~2.0倍。饮奶者和非饮奶者钙摄入量小于EAR人群,比例分别为89.2%和96.3%,非饮奶者钙摄入不足的风险是饮奶者的1.1倍。同时,居民钙摄入量达到和超过RNI人群,比例仅为2.2%,饮奶者和非饮奶者钙摄入量达到和超过RNI人群,比例分别为4.4%和1.6%,饮奶者是非饮奶者的2.8倍。结论:10年间辽宁省居民饮奶率虽然上升,但饮奶量仍处于较低水平,同时影响了居民膳食钙的供给,尤其是农村地区居民饮奶状况亟待解决。
Objective To investigate the status and changes of the milk consumption in Liaoning province in different gender,region,ages and income level. Method Using the data of Nutrtion and Health Surveillance of Chinese Residents in 2002 and 2012,Changes of the percentage of milk consumption,average intake of daily milk and dietary calcium intake were analyzed in different years in Liaoning province. Result The percentage of milk consumption was 22. 5%,the urban was 7 times（ 35. 8% VS 5. 1%） of that rural,females was significantly higher than male,and there was significant differences in age group and income levels（ P 0. 05）. The average intake of daily milk was 34. 10 ± 81. 4 g/d,the urban was 9. 6 times（ 55. 8 ± 99. 1 g/d VS 5. 8 ± 32. 0 g/d） of that rural,and the top income level was 2 times（ 53. 4 ± 85. 7 g/d VS 26. 2 ± 70. 8 g/d） of that bottom income level. Average intake of daily milk among milk consumers was 151. 9 ±107. 8 g/d. However,milk consumers in rural had the lowest level,which was 114. 6 ± 89. 2 g/d and the age group above 60 years old had the highest level,which was 160. 9 ± 116. 1 g/d. Compare with 2002,the percentage of milk consumption increared by 21. 6%（ 18. 5%VS 22. 5%）,the growth of rural and bottom income level was relatively large. The percentage of milk consumption increased by 1. 7 times（ 1. 9% VS 5. 1%） and 1. 1 times（ 8. 7% VS 18. 0%）,respectively. The average intake of daily milk was basically flat. The average intake of daily milk in rural was increased by nealy 1 times（ 5. 8 ± 32. 0 g/d VS 2. 9 ± 23. 9 g/d）,but remained at the lowest level. The average daily intake of dietary calcium was 357. 3 ± 207. 6 mg/d,and the intake calcium among milk consumers was 1. 6 times（ 506. 8 ±224. 1 mg/d VS 313. 9 ± 180. 8 mg/d） that of milk non-consumers. The intake calcium among milk consumers was 1. 5 to 2. 0 times that of milk non-consumers from genders,ages,regions and income level. The proportion of milk consumers and milk non-consumers was less than EAR,which was 89. 2% and 96. 3%,respectively. The risk of insufficient calcium intake among milk non-consumers was 1. 1 times higher than that of milk consumers. The proportion of person with calcium intake reached and exceeded RNI was only 2. 2%. The proportion of milk consumers and milk non-consumers with calcium intake reached and exceeded RNI were 4. 4% and 1. 6%,respectively. The calcium intake among milk consumers was 2. 8 times that of milk non-consumers. Conclusion In the past 10 years,although the rate of milk consumption in Liaoning residents increased,the amount of milk was still at a low level,which affected the supply of dietary calcium,especially in rural areas.
