Abstract:
Objective To understand the dietary nutrients among rural stranded children.Methods 2551 children aged 2 to 7, including 1278 stranded children in the rural areas and another 1273 children served as controls were selected, using multistage stratified cluster random sampling. Dietary survey was performed with three-day weighing dietary method and questionnaire on food intake. Data on diet were analyzed and evaluated by the Dietary Reference Intakes (DRIs) recommend by Chinese Nutrition Society, to evaluate the levels on energy and nutrient intake among stranded children in the rural areas. Results The dietary pattern among rural stranded children mainly consisted of grains and vegetables, but the intakes of animal products, fruits, and snacks were significantly less than in the control group. The intakes of three major energy-producing nutrients were below the recommend nutrient intake. Minerals as calcium, zinc, selenium, kalium and vitamins as vitamin A, B1, B2were insufficient.Most of the rural stranded children took nutrients insufficiently, with 50% lack of adequate energy and 80% of protein, 90% of minerals (calcium, zinc etc.) and vitamins (vitamin B1 and vitamin B2 etc.).Sources from high quality protein was insufficient, only consisting 35% of the total protein, but overabundant (over 64 % ) from the plants. The intake of plant-sourced iron was overabundant, accounted for 87%. Conclusion The dietary pattern was unsatisfactory with insufficient intake of energy-sourced proteins and some nutrients. The sources of energy, protein, and iron were mostly obtained from underbalaneed foods. It is necessary to improve the dietary nutrients status among rural stranded children aged 2-7 years.
