ABSTRACT

Objective To learn the dietary nutrition status among residents in Hangzhou. Methods A cross - sectional study was conducted among 1 744 subjects of 495 families to collect food consumption data through both food - weighting and food - recording method covering 3 consecutive days. The intake of nutrients was calculated using data derived from China Food Composition and further was compared to the dietary reference intakes( DRIs). Results The medians of dietary intake for vegetable,fruit,aquatic product,egg,soy product & nut and milk(269. 4,86. 2,40. 0,22. 3,14. 9 and 0 g/ standard - person(sp)/ d,respectively)were below recommendations,while that of poultry & meat,total salt equivalent and oil(105. 6,10. 4 and 28. 7 g/ sp/ d,respectively)exceeded the recommendations. The medians of energy, protein,carbohydrate and fat intake(2 143. 8 kcal/ sp/ d,74. 5,282. 1and 78. 5 g/ sp/ d,respectively)were either in the recommended ranges or approach to them. The medians of vitamin A,E,B1,B2 and C intake(431. 8 μgRAE/ sp/ d, 11. 2 mgα - TE/ sp/ d,0. 9,0. 9 and 70. 2 mg/ sp/ d,respectively)were not meet corresponding recommended nutrient intakes / adequate intakes(RNIs/ AIs)among all analyzed vitamins. The median of sodium intake(5 217. 9 mg/ sp/ d)was above the proposed intake(PI)for NCD prevention while the medians of calcium,potassium and selenium intake(520. 7, 1 877. 6 mg/ sp/ d and 46. 4 μg/ sp/ d,respectively)were below corresponding RNI/ PI among all analyzed minerals. Conclusion The dietary pattern of residents in Hangzhou was not well - balanced,and that led to inadequate intake of multiple micronutrients though the macronutrients were barely affected.
