Objective To understand the nutritional status and changing trend among Huangpu residents in Shanghai.
Methods Total of 372 residents in Huangpu District of Shanghai were interviewed during a two month period (September to November, 2007)and a multi-stage cluster sampling strategy was used. A 24 h dietary recall method was chosen to collect all food intake information for 3 consecutive days, and a weighting method for condiments consumption. The data were compared to the previous nutrition surveys done in 1992, 2002 and 2005.
Results The protein intake was 92.9g, increased by 10.5g and the energy intake was 9 167.1 kJ, decreased by 1 351.5 kJ, both compared with the data of 1992 respectively. There were 85.8% and 63.7% residents reported consuming at least 80% of Recommended Nutrient Intake (RNl)on protein and energy respectively. Of 79.8% residents showed 300 mg per day in cholesterol intake, while 90.9% residents consumed fiber less than 25 g per day. The percentage of calories from total fat was 35.1% and increased by 4.9% compared with the 1992 data. The intakes of vitamin A, thiamin, riboflavin and ascorbic acid below RNIs were reported in 70.7%, 66.2%, 76.0% and 70.4% residents respectively. The intake of calcium was 639.2mg, increased by 92.9 mg compared with the 1992 data. But only 24.9% residents met the Adequate Intake (Al)of calcium. There were 84.1% and 70.2% residents were found above the RNl or Al of iron and selenium respectively. Both percentages were higher than that those of the 1992 data.
Conclusion Though the average intakes of fundamental nutrients have improved since the nutrition survey in 1992, there were still issues on nutritional deficiency or excess among residents to be addressed and guided scientifically.
