昆明市部分小学学龄期儿童扁平足患病筛查分析.

Objective To investigate the incidence probability and epidemiological characteristics of flat foot in school-age children （7～13 years old） in Kunming, and to provide the evidence for the prevention of flat foot. Methods The incidence of flat foot, age trend, male to female ratio, severity and the incidence of single and double foot of school-age children were analyzed by using the optical foot assessment recording device in the second primary school of Dianchi Resort, the fifth Primary School of Jingkai District, Guolin Primary School and Wenbi Primary School in Kunming. Results The overall incidence of flat foot in 4444 school-age children （7-13 years old） in Kunming was 29.1%. The incidence of flat foot in school-age children of different ages was statistically significant （χ² = 159.887, P < 0.001）. The prevalence was 36.91% at age 7 and 29% at age 13. The incidence of flat feet was 62.49% in boys and 37.51% in girls. There was a statistically significant difference in the incidence of flat feet between boys and girls （χ² = 63.886, P < 0.001）. The prevalence of flat feet in boys of all ages was higher than that in girls.The total incidence of flat foot in school-age children was divided into mild 21.79%, moderate 52.43% and severe 25.78% according to degree. The incidence of flat foot was 89.1% in bipedal type, and there was no statistical significance in the left and right type of flat foot （P > 0.05）. Conclusion The incidence of flat foot in school-age children aged 7-13 years decreases gradually with the increase of age. The incidence of flat foot in girls is lower than that in boys, and the incidence of flat foot in most children is moderate flat foot. For school-age children, flat feet should be prevented, detected and treated as early as possible. [ABSTRACT FROM AUTHOR]
