Abstract：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 Nutrition 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 adolescents with zinc intake less than EAR in 1991 and 2011 were 18.57% and 23.94% respectively. The proportions of residents with dietary 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 respectively. 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.
