摘　　要：目的分析1991-2011年湖北居民膳食锌摄入状况及变化趋势。方法选取1991-2011年"中国健康与营养调查"八轮调查中有完整3 d 24 h膳食调查数据的7岁及以上湖北居民作为研究对象,应用SPSS17.0软件进行统计分析。结果 2011年湖北居民平均每日锌摄入量为11.50 mg/d,成年人高于儿童青少年,男性高于女性,县城、农村高于城市、郊区。男性居民锌摄入量低于平均需要量(EAR)的人群比例高于女性。儿童青少年平均每日锌摄入量从1991年的11.57 mg下降到2011年的10.26 mg,锌摄入量低于平均需要量(EAR)的人群比例1991年和2011年分别为18.57%和23.94%。1991-2011年,膳食锌摄入量低于平均需要量(EAR)的人群比例城市从19.25%升至37.82%,郊区从14.34%升至33.19%,县城从19.14%降至14.13%,农村从27.87%降至13.51%。结论湖北居民普遍存在膳食锌摄入不足。应重点关注儿童青少年以及城市和县城居民锌摄入下降的趋势,需要进行适当干预以增加膳食锌摄入量。Objective To analyze the dietary intake of zinc and its changing trend among residents in Hubei Province from 1991 to 2011. Methods The residents aged 7 years and above with full 3-day 24-hour dietary recall data in China Health and Nu- trition Survey （ 1991, 1993, 1997, 2000, 2004, 2006, 2009 and 2011） in Hubei Province were selected as the research objects. Data were analysed using SPSS 17.0 software package. Results The average daily zinc intake of the residents in Hubei Province in 2011 was 11.50 mg/d. The average daily zinc intake was higher in adults than in children and adolescents, higher in males than in females, and higher in counties and rural areas than in cities and suburban areas. The proportion of male residents with dietary zinc intake less than estimated average requirement （EAR） was higher than that of female ones. The average daily zinc intake of children and adolescents was decreased from 11.57 mg in 1991 to 10.26 mg in 2011, and the proportions of children and adoles- cents with zinc intake less than EAR in 1991 and 2011 were 18.57% and 23.94% respectively. The proportions of residents with di- etary zinc intake less than EAR increased from 19.25% and 14.34% in cities and suburban areas in 1991 to 37.82% and 33.19% in 2011 respectively, but decreased from 19.14% and 27.87% in towns and rural areas in 1991 to 14.13% and 13.51% in 2011 re- spectively. Conclusions Low dietary zinc intake is still a problem among the residents in Hubei Province. Special attention should be paid to the declining trend of dietary intake of zinc among children and adolescents as well as residents in cities and towns. It is necessary to increase dietary intake of zinc by appropriate nutrition interventions.
