The Relationship Between 7-9 Years Old Children's Caries And Body Mass Index In Taiyuan

Objective:Through the study of the relationship between the decayed missing filled teeth(DMFT)and the body mass index(BMI)in 7-9 years old children in Taiyuan and by the oral health questionnaire,to analyze the children's caries status.The correlation between body mass index and other factors related to caries provide a theoretical basis for clinical analysis of the relationship between caries and nutritional status in children aged 7-9years in Taiyuan.Methods:1.This study selected 300 children aged 7-9 years from December 2017 to December 2018,who had treatment at the Shanxi Medical University School and Hospital of Stomatology,including 157 boys and 160 girls.The professionally trained inspector used uniform mirrors and probes for oral examinations,according to the quadrant(5-6-7-8),according to the formula Caries rate(%)=number of people affected/number of people examined×100%,and Decayed missing filled teeth=decayed,missing,filling teeth/number of people inspected calculated the decayed missing filled teeth(DMFT),and parents filled out the questionnaire.2.At the same time of the day(8:00-10:00am),using the corrected height and weight measuring instrument to measure the children's height and weight and record the data,according to the formula Human Body Mass Index(BMI)=weight(kg)/[height(m)]~2,calculate the BMI value.According to the 8th edition of Children's and Children's Hygiene published by Beijing People's Health Publishing House in 2017,the classification of children's BMI is defined.Among them,"Chinese school-age children malnutrition screening(WS/T456-2014)"defines wasting,"Chinese school-age children BMI is overweight,The Obesity Screening Criteria evaluates overweight and obesity,between which the normal weight is between the two,and the BMI is divided into four groups:wasting,normal,overweight,and obese.3.Statistical analysis was performed using SPSS 21.0 software.In the questionnaire,the continuity test was tested for normality,the variables that conformed to the normal distribution were represented X±S,and the comparison between groups was analyzed by variance;the variables that did not conform to the normal distribution were expressed by the median(P25,P75).Two sample comparisons were performed using the Wilcoxon rank sum test,and multiple sets of samples were compared using the Kruskal-Wallis rank sum test.The categorical variables were described by counting(percentage)and the comparison between groups using thec~2 test.Spearman was used to test the correlation between caries and body mass index,and multivariate analysis was performed by stepwise logistic regression analysis.P<0.05 was considered statistically significant.Results:1.The DMFT values were different in different children's nutritional status.The DMFT value of the children in the weight loss group was the largest,which indicated that the child's caries were severe,and have highest rate of caries(93.2%),P<0.05 was statistically significant.BMI and DMFT were negatively correlated by scatter plot analysis.Spearmancorrelation coefficient was weakly correlated with-0.17,and P<0.05 was consideredstatistically significant.2.Some data in the questionnaire showed that the rate of caries in children born by caesarean section was 88.5%,which was higher than that in children born with natural childbirth.P<0.05 was statistically significant.3.Through logistic regression analysis of caries and BMI,it is concluded that children's sleep quality will affect children's caries and nutritional status,P<0.05 was statistically significant.Conclusion:1.7-9 years old children's caries are negatively correlated with body mass index,and wasting children have the highest rate of caries in taiyuan.2.Children born by caesarean section have higher rates of caries.3.Sleeping quality affects children's caries and body mass index.
