Abstract
PURPOSE: To report the prevalence and distribution of eye conditions and visual impairment and associations with early social and biological factors using parental report of diagnosed eye conditions and additional chronic illnesses. DESIGN: Population-based, cross-sectional study. PARTICIPANTS: We included 14 981 children, aged 3 years, participating in the United Kingdom Millennium Cohort Study. METHODS: Data on demographic, socioeconomic, and maternal and child health factors were obtained by maternal report through structured interview and verbatim reports of diagnosed eye problems and additional chronic illnesses were recorded. Multinomial regression analyses were used to calculate risk ratios of the association of eye disease (with or without associated visual impairment), with socioeconomic and early life factors. MAIN OUTCOME MEASURES: Parental report of diagnosed eye conditions and other chronic illnesses. RESULTS: Overall, at 3 years, 5.7% (95% confidence interval, 5.2-6.3%; n = 881) of children had ≥ 1 eye condition with 0.24% (0.15-0.3%; n = 45) reported to have associated visual impairment. In the majority, time of onset was reported to be the first year of life. Eye disorders without report of visual impairment were independently associated with lower socioeconomic status, decreasing birth weight, and prematurity. Visual impairment was more likely in those of low birthweight for gestational age and from an ethnic minority group. Maternal illnesses during pregnancy were associated with eye disease without reported visual impairment, as was white ethnicity. CONCLUSIONS: Good research opportunities exist within the context of population-based general health surveys to use parental report to estimate minimum prevalence, investigate associations of eye disease with a broad range of environmental factors, and as a mechanism for "flagging" individuals with eye disease in a population sample for further study. Our findings regarding the association of parentally reported childhood eye disease with early life factors such as modest degrees of prematurity, ethnicity and maternal ill-health warrant further investigation.
