| Objective:(1)To investigate the nutritional status of preschool children in Zawa Town,Moyu County,Hotan District,Xinjiang,and provide the basis for the next stage of nutritional intervention research;(2)To improve children’s nutritional status and provide new ideas for nutrition poverty alleviation through nutritional intervention with "multi-beneficial point" nutritional chewable tablets.Methods:(1)947 pre-school children were selected by stratified sampling of 947 preschool children in Toglak village,Inwustang village and Baxakqi village kindergarten in Zawa town,Moyu county,Hotan district.The nutritional status was investigated by questionnaire,dietary survey,physical examination,hemoglobin test and trace element test in children with anemia.(2)The method of sampling by cluster stratified sampling using the method of comparative study. 947 pre-school children were selected as intervention group and 247 pre-school children were selected as control group in Zawa Town,Inwustang Village and Bashakqi Village Kindergarten in Moyu County,Hotan District.The intervention time was one year,and the children were analyzed by physical examination,hemoglobin and intervention,before and after intervention.Results:(1)Nutritional status: The average daily food intake of children did not include product,milk,soybean,cereal and egg intake.Meat and poultry food intake was slightly inadequate,.Accounting for 84.00% of the appropriate intake,fruit and vegetable intake was seriously inadequate,accounting for only 41.28% of the appropriate intake,33.60% respectively,.Salt intake exceeded the standard,accounting for 160.00% of the appropriate intake.The average daily energy intake per person and the main nutrients intake of three major nutrients carbohydrate,protein,fat intake satisfied RNIs,dietary fiber intake seriously inadequate,an average of only 50% of RNIs 16.12%,vitamins A、 vitamins C,vitamins D,calcium,iron intake insufficient RNIs;three major nutrient function ratio of each age group protein average heat energy supply ratio 16.84% of total energy,fat average heat supply ratio 29.48% of total energy,carbohydrate average heat supply ratio accounted for 53% of total energy.The animal fat intake accounted for 55.13%of the total fat,plant fat intake 42.42% of the total fat,and the growth and development of children showed that the growth retardation rate was 10.77%,the low body weight rate decreased to 11.19%,and the anemia rate of children decreased to 8.06% the difference was statistically significant.(c2=8.017,P<0.05).The blood microelement content rose to31.70±20.96(μmol/L),zinc to 63.79±10.34(μmol/L),calcium to 1.27±0.12(mmol/L),magnesium to 1.25±0.15(mmol/L),and iron to 6.42±0.55(mmol/L).Conclsion:(1)The dietary intake of calories and nutrients in preschool children in Zawa Town,Hetian Moyu County,Xinjiang,is up to standard,but the types of meals are seriously uneven,which makes the intake of dietary fiber,calcium,iron,vitamins C、 vitamins A、 vitamins D and vitamins and B groups seriously inadequate.(2)The growth and development level of children in this area is low,the height and weight are lower than the national standard of our country,and the growth retardation rate,body weight rate and anemia rate are higher than the national average.(3)After the intervention of nutritional supplement,the growth retardation rate,low body weight rate and anemia rate of children all decreased,and the content of blood microelement increased.The height and weight growth of children in the intervention group was significantly higher than that in the control group,and the nutritional status was improved,and the effect of the intervention was remarkable. |
