Understanding the trends, clustering, and risk factors of pinworm infection in preschool settings: A repeated cross-sectional multi-center study between 2019 and 2024.

ABSTRACT:

Background

Pinworm (Enterobius vermicularis) remains the most prevalent helminth among preschool-aged children worldwide. Despite China's rapid development and decades of mass deworming, pinworm infection persists as a significant paediatric public-health problem. In this study, we aimed to understand the trends, clustering, and risk factors of pinworm infection in preschool settings of Jiangsu, China.

Methods

A repeated cross-sectional study was conducted in 45 counties of Jiangsu Province from 2019 to 2024. Multi-stage cluster convenience sampling was applied. Each year, one rural preschool and one urban preschool were selected per county. The sample size for each school was 229 to obtain a 5% margin of error, an arbitrary design effect of 1.5 for a prevalence estimate of
