Flatfoot is common in children and its prevalence influenced by several factors. This study investigated the role of age and type of foot wear as predictors of flatfoot in school age children in urban and rural areas in south-western Nigeria.
560 children between 6 and 12 years, divided into two groups; rural and urban were studied. Each subject's static footprint was taken on a white duplicating paper after which the instep was measured for classification into high arch, normal, flat or severe flat. The BMI of each subject was calculated from the anthropometric data. The type of footwear with which the subjects were shod was also recorded. Data analysis was by Epi Info statistical package version 3.5.1 (2008).
Chi-square showed a significant (p<0.05) association between the presence of flatfoot, age and type of footwear. Comparison of the prevalence of flatfoot by age group indicated a significant difference at age 10 years. Simple logistic regressions, however, showed that age was a significant (p<0.05) predictor for flat foot while the type of footwear was not.
In this study, age is the primary predictor for flatfoot while the type of footwear is not.
扁平足在儿童中很常见，其患病率受多种因素影响。本研究调查了年龄和鞋类类型作为尼日利亚西南部城乡学龄儿童扁平足预测因素的作用。
对560名6至12岁的儿童进行研究，分为农村和城市两组。让每个受试者在白色复写纸上留下静态脚印，然后测量足弓以分类为高弓足、正常足、扁平足或重度扁平足。根据人体测量数据计算每个受试者的体重指数。还记录了受试者所穿的鞋类类型。使用Epi Info统计软件包3.5.1版（2008年）进行数据分析。
卡方检验显示扁平足的存在、年龄和鞋类类型之间存在显著（p<0.05）关联。按年龄组比较扁平足患病率表明10岁时存在显著差异。然而，简单逻辑回归显示年龄是扁平足的显著（p<0.05）预测因素，而鞋类类型不是。
在本研究中，年龄是扁平足的主要预测因素，而鞋类类型不是。
