ABSTRACT
Objective To ascertain the energy and main nutrients intake among residents in Changning District of Shanghai.Methods A stratified multistage random survey was conducted among 72 families to collect their ADI (acceptable daily intake) of nutrients through 3 d 24 h dietary recall and family condimentweigh surveys in comparison with recommended ADI.Results A total of 148 persons were included,of whom males were 75 and females 73.Every standard person daily vitamin B1,B2,A and calcium intake was relatively low.Calcium intake for 85.81% of persons was was lower than EAR.Vitamin A intake for 62.84% of persons was lower than EAR.Vitamin B1 intake for 77.7% of persons was lower than EAR.Vitamin B2 intake for 73.65% of persons was lower than EAR.In various age groups,except for women aged 18-49,contribution rate of fat in total energy exceeded recommended ADI.Conclusion Energy and main nutrients intake basically meet the needs of residents in Changning district of Shanghai.But some nutrients were still deficient severely.The source of energy nutrients was not well-balanced.More intake is recommended of milk and dairy product,soybean and bean product,vegetables and fruit.
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.
ABSTRACT
417 employees of construction and quarry site at 8 quarry companies were investigated in Hong Kong. All the respondents were interviewed with a diet questionnaire which included the following foods: a) meat; b) liver; c) lung; d) blood; e) fish and shellfish; f) eggs; g) fresh fruits; h) beans and peas; i) carrots; j) leafy green vegetables; k) milk and ic-ecream; 1) cream and butter; m ) fried foods; n ) margarine; o) lard; p) whloe wheat. Each subjects lung function was measured by Vitalograph as the machine which recorded the measure value, predict value according to the six, age and hight of the subject. FYCC (FVC meaure value/FVC predict value), FEV1 (FEV1 measure value/FEV1 predict value) and FEV1- FVCM (FEVl/FVC) were used as indicators for luug function in the paper and the demarcation between normal and poor lung function was 80% for FVCC and FEV1C while 75% for FEV1FVCM of predict value. The investigation results showed that the workers could pay more attention to food and health. They selected balanced diet and took more high-protein, high-vitamins and high-fiber foods such as fish, vegetables and fruits while high-fat or high-cholesterol foods such as animal viscera and lard were less taken. The results of Chi-squre analysis for dietary intake and lung function showed:1) None of the differences of food intakes between normal and poor FVCC reached statistical significance; 2) There were si-gnificent differences between normal and poor FEV1C in the intakes of liver and lung (P
