| Ulanqab belongs to the contiguous poverty-stricken area of Inner Mongolia Autonomous Region.Compared with the developed areas,it has the characteristics of relatively less kinds of food materials,relatively lack of kindergarten talents,obvious regional characteristics of eating habits,relatively low population density,and public kindergartens as the main schools.At present,there are few researches on preschool children’s diet in this area.This study fills this gap and provides theoretical and practical basis for the subsequent formulation of reasonable dietary standards for kindergartens in Ulanqab,Inner Mongolia.In this research,the stratified random sampling method,combined with the weighing method and questionnaire survey method,was used to study the differences in children’s intake of various nutrients and various types of food under different conditions.The main findings are as follows:1.Analysis of various food intake and influencing factors of kindergarten childrenIt can be seen from the comparison of the daily food consumption of nine kindergarten children per capita with the recommended amount of the balanced diet pagoda of Chinese preschool children(hereinafter referred to as the recommended amount).The consumption of coarse grains and fine grains for children is 115.30% of the highest recommended amount;The consumption of beans is 197.85% of the highest recommended amount;The consumption of meat,poultry and fish is 141.53% of the highest recommended amount;Milk consumption is only 37.03% of the minimum recommended amount;Egg consumption is 49.98% of the recommended amount;The fruit consumption is 30.57% of the minimum recommended amount.Among 9 kindergartens,the average number of kindergartens that use milk or fruit for meals daily is 6.40,and there are 7.90 in terms of milk intake.Children in these kindergartens can meet the daily milk drinking standard,but the average milk consumption Below the recommended amount of 220.39 g.(1)The level of kindergarten,the age of health care doctors and the regional economic level are positively correlated with the daily milk consumption of children.Different food standards for different kindergartens did not produce significant differences in children’s daily milk consumption.(2)In terms of children’s consumption of beans and vegetables,only health medical level has a significant impact.(3)The per capita food standard has a significant impact on children’s meat consumption,showing that the higher the per capita food standard,the more meat intake,the highest garden is higher than the recommended consumption of 54.71%.2.Analysis of nutrient intake and influencing factorsThe daily per capita calorie intake of 9 kindergarten children is 1460.61 Kcal,which is within the reference range of "Reference Intake of Dietary Nutrients(DRIs)of Chinese Residents"(hereinafter referred to as DRIs Reference)from 1300 Kcal to 1700 Kcal.Among them,the ratio of calorie intake of breakfast and lunch to the calorie intake of the whole day in 8 kindergartens is within the reference range of DRIs.There were 7 kindergarten children whose noon calorie intake accounted for the whole day calorie intake in the DRIs reference interval,5 kindergarten children’s dinner calorie intake accounted for the whole day calorie intake ratio beyond the DRIs reference interval;Protein intake accounted for 14.68% of the total energy intake,which was 0.68% higher than the upper reference limit of DRIs;Animal protein and soy protein should account for 30%-50% of the total dietary protein,and the average proportion of children in 9 kindergartens is 62.18%;Fat intake accounted for 35.96%of the total caloric intake,which is 5.96% higher than the children’s DRIs upper reference limit.In terms of fat sources,62.43% of 9 kindergarten children’s fat sources were animal fats,much higher than animal and plant fats 50% of each reference value;The daily per capita intake of calcium is 384.82mg/d,which is far lower than the reference value of DRIs of740.43mg/d-774.07mg/d;The daily per capita intake of zinc is 9.8mg/d,which is lower than the reference value of 11.11mg/d-11.61mg/d in DRIs;The daily per capita intake of iron is14.92mg/d,which is higher than the reference value of DRIs 12mg/d and lower than the tolerance value of 30mg/d for children of this age.(1)9 kindergarten children’s calcium intake was significantly positively correlated with the kindergarten level,health care seniority,and regional economic level.(2)The intake of iron and zinc is significantly related to the medical education level and regional economic level.Although zinc intake has improved from the 2005 census data,it still has not reached the reference standard. |
