| Research purpose: To provide basic data for further research on daily energy consumption and nutrition intake of preschool children of Jiangsu Province,with the aid of tri-axis accelerometer to monitor body movements,the author carried out an investigation on the dietary nutrition status of preschool children and compared the physical activities and dietary nutrition of boys and girls in different ages who came from southern and northern Jiangsu and analyzed the reasons.Research approaches: Selecting 224 preschool children from southern and northern Jiangsu,including 41 from Nanjing,71 from Zhenjiang,48 from Huai'an,64 from Xuzhou.All of them are aged between 3 to 6.Their food preference,dietary habits,living habits and other relevant information are collected through nutrition questionnaires and on-site inspection.Various scores correspond to different levels in the nutrition questionnaire.These preschool children were required to wear tri-axis accelerometer for a week so as to get data which reflect activity intensity and time of different individuals,as well as energy consumption of activity.Then the software JMP was employed to conduct statistical analysis with the data.Research Results:1?In food selection,,preschoolers' staple food,fruits,meat and dairy scored higher while coarse grains and beans was lower.Southern Jiangsu girls eat less coarse grains than northern Jiangsu girls(P < 0.05).Southern Jiangsu boy is obviously better than the northern boys in aquatic products and eggs intake(P < 0.05).At the age of 5 and 6,children's dietary choice significantly shows regional differences,5 years old children's intake of aquatic products and eggs in the south of Jiangsu is better than that of 5 years old children in northern Jiangsu(P < 0.05),but drinking water is not as good as the boys in northern Jiangsu(P < 0.05),6 years old children's intake of eggs in the south of Jiangsu is better than that of north Jiangsu children 6 years of age(P < 0.05).2?In dietary habits,pre-school children fried foods and sweet drinks score higher,5-year-old children in southern Jiangsu to eat fried foods was significantly better than 5-year-old children in northern Jiangsu(P <0.05).The situation of picky eaters and sweet snacks was lower than that of northern Jiangsu boys(P <0.05).There were significant regional differences in the dietary habits of 4-year-olds and 5-year-olds,that is,4-year-old children in northern Jiangsu were more likely to eat more snacks than those of 4-year-old children in northern Jiangsu(P <0.05).3?In terms of lifestyle,preschool children wash their hands before meals and morning brushing score higher,the boys and girls in southern Jiangsu morning brushing habits are significantly better than boys and girls in northern Jiangsu(P <0.05),rinse after meals and the habit of watching TV is lower.Life habits between children of 5 and 6 years old was significantly regional different,that is,5-year-old children in southern Jiangsu morning brushing the situation was significantly better than 5-year-old children in northern Jiangsu(P <0.05),6-(P <0.05).4?From different levels of physical activity intensity,northern Jiangsu boy's static behavior(SB),Mid-intensity physical activity(MPA),high-intensity physical activity(VPA),and high-intensity physical activity(MVPA)were significantly higher than those in southern Jiangsu(P <0.05),and the duration of physical activity(SB),moderate intensity physical activity(MPA)),MPA,VPA and MVPA in northern Jiangsu were significantly longer than those in southern Jiangsu(P <0.05).There were significantly regional differences in the physical activity intensity of 3-year-old,4-year-old and 5-year-old children.SB in 3-year-old children in northern Jiangsu was significantly higher than that in children aged 3 years(P <0.05)(P <0.05).SB,VPA and MVPA in 5-year-old children in northern Jiangsu were longer than those in children aged 5 years in southern Jiangsu,but the duration of low-intensity physical activity(LPA)was less than that of southern Jiangsu 5 Year old children(P <0.05).5? In the area of energy consumption,the average daily physical activity of the boys in North Jiangsu was significantly higher than that in southern Jiangsu(P <0.05).The average daily and average daily physical energy consumption of girls in northern Jiangsu were significantly higher than those in southern Jiangsu(P <0.05).There were significant regional differences in the energy consumption of only 4-year-old children,ie,the average daily and average daily physical energy consumption of 4-year-old children in North Jiangsu was significantly higher than that in 4-year-old children in southern Jiangsu(P <0.05).Conclusion:1?Jiangsu Province preschool children staple food,fruit,meat and milk intake is more adequate,but coarse grains and beans generally inadequate intake,and the southern Jiangsu girls intake of coarse grains was significantly lower than the girls in northern Jiangsu.From the differences analysis of regional and gender,the southern Jiangsu boys were significantly more than northern Jiangsu,from the regional and age differences,the southern Jiangsu 5-year-old children were significantly more than northern Jiangsu,southern Jiangsu 6-year-old children intake of eggs Significantly more than the northern Jiangsu,may be due to the northern Jiangsu region for parents of various types of food intake and other nutritional knowledge of the different awareness of nutrition.2,Preschool children in Jiangsu Province barely or do not eat fried foods and sweet drinks,and 5-year-old children in southern Jiangsu to eat fried foods was significantly better than 5-year-old children in northern Jiangsu,but picky eat and eat sweet snack habits still need to be corrected in time,from the regional and gender differences in the analysis,the southern Jiangsu boys were significantly more than northern Jiangsu,from the regional and age differences analysis,four-year-old children in southern Jiangsu eat sweet snacks more than 4-year-old children in northern Jiangsu,With parents and kindergarten teachers on the guidance of preschool children.3,Most preschool children in Jiangsu Province have good living habits,such as washing hands before meals,morning brushing,Jiangsu boys and girls morning brushing habits are significantly better than the boys and girls in northern Jiangsu,and 5-year-old children in southern Jiangsu morning brushing The habit is obviously better than the 5-year-old children in northern Jiangsu;but the issue of watching TV while eating is widespread,there is no regional differences,which may be the negative impact brought by improvement of material living standards,the widespread use of Internet products.The habit of rinse after meals is also need to be improved,of which the 6-year-old children in southern Jiangsu are obviously less than the 6-year-old children in northern Jiangsu.4,Children in northern Jiangsu and 4-year-old children in high-intensity physical activity time were 62.41 min / d and 61.74 min / d,besides,the other preschool children in the high-intensity physical activity time is basically less than the recommended 60 min per day,which may be caused by parents and kindergarten teachers' over-protection of children's safety,to some extent,restricts the children free to carry out physical activity.5,Regardless of high-intensity activities or energy consumption,pre-school children in southern Jiangsu is less than the preschool children in northern Jiangsu.Northern Jiangsu children may have larger area for physical activities,which provide them with good external conditions. |
