Factors associated with subsequent eye care for children in Taiwan: a population-based historical cohort study.

Purpose: To investigate patterns and factors associated with subsequent eye care for Taiwan's children.

Methods: We conducted a population-based historical cohort study of 2464 children aged between 3 and 12 years old from the 2005 National Health Interview Survey (NHIS). Participants' ocular conditions were identified based on 2005 NHIS questionnaire answers given by caregivers. Subsequent eye care data was obtained from 2006 and 2007 National Health Insurance claim data. Eye care related to these children's ocular conditions was defined by physician's diagnosis using the International Classification of Diseases version 9 clinical modification codes. Poisson regression with robust variance estimation was used to determine factors associated with eye care use.

Results: Of the 2464 children, 712 (28.9%) had ocular conditions in 2005, and 56.5% and 44.7% of them didn't receive eye care during the subsequent 1- and 2-year periods, respectively. Among those with ocular conditions, the 3-4-year-olds were least likely to receive eye care in the subsequent 1 and 2 years. Children with highly educated fathers were more likely to receive eye care in the subsequent 1-year period. Sex, family income, level of mother's education, residential area and eye care resources were not significant factors for children with ocular conditions receiving subsequent eye care within either 1 or 2 years.

Conclusions: Despite the fact that Taiwan has a National Health Insurance Program, lack of subsequent eye care remains high, even when a child's ocular condition is known by the caregiver. Determinants associated with follow-up eye care must be considered when designing eye care enhancing programs for children.
