青岛市崂山区6年级儿童足部异常筛查分析
Analysis of Screening for Foot Abnormalities in Children in Grade 6 in Laoshan District, Qingdao

目的：调查青岛市崂山区6年级儿童扁平足的流行状况，探究其与性别、BMI的关系，为预防扁平足提供参考。方法：使用足迹动态筛查仪对青岛市崂山区17所小学校6年级儿童共1408人进行足迹筛查，分析其患病率、男女比例、BMI。结果：青岛市崂山区1408名6年级儿童总体扁平足检出率为22.6%，高弓足的检出率为5.3%。男童扁平足检出率为25.7%，女童扁平足检出率为19.4%。其检出率具有统计学意义(χ² = 5.409, p < 0.05)，6年级男生中扁平足的检出率高于女生。男童高弓足检出率为2.9%，女童高弓足检出率为7.9%。其检出率具有统计学意义(χ² = 14.662, p < 0.01)，6年级女生高弓足的检出率高于男生。超重组占所有检出扁平足儿童的15.7%，肥胖组占21.4%，体重过轻组则占4.1%。结论：6年级儿童中，男性发生扁平足的风险比女性更高，女性发生高弓足风险比男性更高。超重与肥胖者发生扁平足的风险可能更高。对于学龄期儿童的扁平足应该做到早预防、早发现、早纠正。
Objective: To investigate the prevalence of flatfoot in grade 6 children in Laoshan District, Qingdao City, and to investigate its relationship with gender and BMI, in order to provide reference for the prevention of flatfoot. Methods: A total of 1408 children in grade 6 in 17 primary schools in Laoshan District, Qingdao was screened for footprints using a footprint dynamic screener, and their preva-lence, male/female ratio and BMI were analyzed. Results: The overall flatfoot detection rate of 1408 children in grade 6 in Laoshan District, Qingdao was 22.6%, and the detection rate of high arched feet was 5.3%. The detection rate of flatfoot in boys was 25.7% and in girls was 19.4%. The detec-tion rate was statistically significant (χ² = 5.409, p < 0.05) and the detection rate of clubfoot was higher among boys than girls in grade 6. The detection rate of high arched feet was 2.9% in boys and 7.9% in girls. Their detection rates were statistically significant (χ² = 14.662, p < 0.01), with higher rates of high arched feet among girls than boys in grade 6. The overweight group accounted for 15.7% of all children with detected flat feet, while the obese group accounted for 21.4% and the underweight group for 4.1%. Conclusions: In grade 6 children, males were at higher risk of flatfoot than females, and females were at higher risk of hyperkyphosis than males. The risk of flatfoot may be higher in overweight and obese individuals. Early prevention, detection and correction of flatfoot in school-age children should be achieved.
