ABSTRACT

Objective To analyze the intake and changes of food and nutrients in 223 residents of Yangpu District from 2011 to 2015. Methods From the China Nutritional Transition Cohort Study in 2011 and 2015, the data in the study was obtained on Yangpu District′s residents aged 2 and above.A dietary survey was conducted using the 3-day 24-hour dietary recall and condiment weighing method to obtain data on food and nutrients intake per reference man per day and the nutrient source of energy, and to analyze the intake status of different years. Results The intake of vegetables, fruits, livestock and poultry, aquatic products, eggs, milk and dairy products, soybeans and nuts, edible oil and salt per reference man per day was lower in 2015 than in 2011.The insufficient intake proportions of cereals and tubers, vegetables, fruits, aquatic products, eggs, milk and dairy products, soybeans and nuts, and edible oils were 56.0%, 84.0%, 98.2%, 56.0%, 70.2%, 97.8%, 85.3% and 91.1%, respectively, the excessive intake proportion of livestock and poultry meat was 51.6%;the intake of energy, protein, fat and micronutrient per reference man per day in 2015 was lower than in 2011, and the insufficient intake proportion of energy, protein, vitamin A, vitamin B1, vitamin B2, vitamin C, and calcium were 84.0%, 56.4%, 97.3%, 93.8%, 93.3%, 90.2% and 91.6%, respectively.In 2011 and 2015, it was found that residents who had the proportions of energy supply from carbohydrate lower than 50% accounted for 64.6% and 49.8%, those who had the proportions of energy supply from protein higher than 15% accounted for 76.2% and 40.4%, and those who had the proportions of energy supply from fat higher than 30% accounted for 76.7% and 72.9%. Conclusion In 2011-2015, the food and nutrients intakes among community residents in Yangpu District generally decrease, showing the coexistent problems of insufficient and excessive food intake, and the insufficient intake is serious.The insufficient intake of energy, vitamins and calcium is still a severe problem.And the dietary structure is not rational; the proportions of energy supply from three major nutrients are unbalanced.It is suggested that nutrition education for residents should be enhanced.
