To investigate the prevalence of abnormal foot arch morphology and its associated factors among primary and secondary school students in Ganzhou City, so as to provide evidence for the prevention of such abnormalities.
From November 2023 to May 2024, a questionnaire was conducted among 1 013 primary and secondary school students, who were selected from one primary school and one nine-year continuous school with stratified cluster random sampling method. Professional equipment, including 2D foot scanning and plantar pressure plates, was utilized to screen pupils for abnormal foot arch morphology (including flatfoot and high-arched foot). The Chi-square was employed for intergroup comparisons, whilst multifactorial Logistic regression analysis was utilized to investigate the associated factors for the occurrence of foot morphological abnormality of arch among students.
The prevalence rate of flatfoot among primary and secondary school students at 61.1%, with bilateral cases accounting for 37.5% and unilateral cases for 23.6%; the prevalence of high-arched foot was 8.0%, comprising 3.9% in both feet and 4.0% in one foot. The prevalence rates of flatfoot among boys and girls were 68.7% and 53.6% respectively. Multivariate Logistic regression analysis revealed that boys had a 1.45 times higher risk of developing flatfoot compared to girls (OR=1.45, 95%CI=1.05-2.02), primary and secondary students aged 6-8 and 9-10 had 4.00, 3.81 times higher risk of flatfoot respectively compared to those aged 15-16 (OR=4.00, 3.81, 95%CI=2.18-7.36, 2.08-6.99) (all P < 0.05). Compared to girls, boys had a lower risk of developing high-arched foot (OR=0.52, 95%CI=0.28-0.95), primary and secondary students who frequently corrected their sitting and standing posture also had a lower risk of high-arched foot (OR=0.30, 95%CI=0.10-0.88) (both P < 0.05).
The prevalence of abnormal foot arch morphology among primary and secondary school students is relatively high, with exercise habits, and postural behaviour identified as associated factors. It is recommended to enhance early screening and behavioural interventions for key populations, thereby advancing the prevention and correction of foot morphological abnormality of arch.
