Research On The Relationship Between Overweight/Obesity And Nutrients Of Children Aged 6-12 Years In The Urban Of Chongqing

Objective To investigate the effect of dietary nutrients' intake of overweight or obesity for children,provides a scientific basis for the prevention of childhood obesity.Method By cluster sampling method,6260 children in five primary schools of Chongqing met the inclusion criteria.A cross-sectional nutrition epidemiological survey was conducted,including anthropometry and dietary survey by food frequency questionnaire.And the factors that may cause overweight /obesity factor are analyzed by Logistic regression analysis.Results(1)The detection rate of overweight and obesity were 16.59%(1000/6028)and 11.28%(680/6028);the detection rate of boys' overweight and obesity were 19.11%(595/3114)and 13.74%(428/3114);the detection rate of girls' overweight and obesity were 13.90%(405/2914)and 8.65%(252/2914).(2)Dietary intaking of carbohydrates,dietary fiber,VA,VB1,VB6,VB12,niacin,folate,Na,Fe,Zn,Cu increased incrementally with age,and difference between groups was statistically significant(P<0.01).(3)Overweight or obese children' daily macronutrients(Protein:77.44 g vs.74.97 g,P<0.05)and micronutrients(VA:989.02?gRE vs.939.42?gRE;VB1:0.81 mg vs.0.79mg;VB2:1.16 mg vs.1.12mg;VB6: 1.16 mg vs.1.12mg;VB12:8.91?g vs.8.31?g;Folate:304.44?g vs.295.08?g;Niacin:13.00 mg vs.12.42mg;Fe:13.16 mg vs.12.86mg;Zn:11.71 mg vs.11.43 mg,P<0.05)intaking were higher than the normal control group'.(4)Overweight or obese children' daily intaking of energy,protein,carbohydrates,dietary fiber,VA,VB1,VB2,VB6,VB12,folate,niacin,Na,Ca,Fe,Zn,Se,Cu were higher than the normal control group' at the age of 7(P<0.05);Overweight or obese children' daily intaking of dietary fiber,VA,folate were higher than the normal control group' at the age of 10(P<0.05);Overweight or obese children' daily intaking of protein,VA,VB1,VB2,VB6,VB12,folate,niacin,VC,Na,Fe,Zn,Se were higher than the normal control group' at the age of 11(P<0.05);Overweight or obese children' daily intaking of energy,protein,carbohydrates,VA,VB1,VB6,VB12,niacin,Fe,Zn,Se were higher than the normal control group' at the age of 12(P<0.05).(5)Binary Logistic Analysis showed that parental education levels,income,birth weight are influencing factors of overweight and obesity(P<0.05).Conclusion The detection rate of overweight and obesity are high and growing rapidly in the urban of Chongqing,The results showed that overweight or obese children 's macronutrients and micronutrients intake were higher than normal children,suggesting that dietary intake of nutrients may be one of the influencing factors of overweight and obesity on children,We should strengthen health education and comprehensive intervention of overweight and obesity,promoting children's physical and mental development.
