Abstract

Purpose: Several studies suggest that myopia is more frequently observed in first-born compared to later-born children. However, it is unknown whether the prevalence of myopia in alpha birth order differs between only-children and first-borns with siblings.

Methods: In this post-hoc study, we analyzed weighted data from the nationwide, representative German Health Interview and Examination Survey for Children and Adolescents (KiGGS) and assessed the relationship between birth order and the prevalence of refractive anomalies in study participants aged 11-17 years (n = 3,429).

Results: Our results showed that there was a significantly higher percentage of self-reported myopia in only-children as compared to first-borns with siblings (34.5% vs 28.2%, p = 0.001). A logistic regression model with myopia as dependent variable and only-child status as independent variable adjusted to age, sex, body-mass index, socioeconomic and migration status confirmed that only-child status was independently and positively associated with myopia (odds ratio = 1.396, 95%-confidence interval = 1.166-1.671, p < 0.001). However, no such relationship was found for hyperopia (p = 0.203).

Conclusions: Myopia, but not hyperopia, was significantly and positively related to only-child status, irrespective of confounders as age, sex, body-mass index, as well as socioeconomic and migration status. Further research is needed to decipher the pathophysiological mechanisms underlying this relationship.

期刊介绍: Ophthalmic Epidemiology is dedicated to the publication of original research into eye and vision health in the fields of epidemiology, public health and the prevention of blindness. Ophthalmic Epidemiology publishes editorials, original research reports, systematic reviews and meta-analysis articles, brief communications and letters to the editor on all subjects related to ophthalmic epidemiology. A broad range of topics is suitable, such as: evaluating the risk of ocular diseases, general and specific study designs, screening program implementation and evaluation, eye health care access, delivery and outcomes, therapeutic efficacy or effectiveness, disease prognosis and quality of life, cost-benefit analysis, biostatistical theory and risk factor analysis. We are looking to expand our engagement with reports of international interest, including those regarding problems affecting developing countries, although reports from all over the world potentially are suitable. Clinical case reports, small case series (not enough for a cohort analysis) articles and animal research reports are not appropriate for this journal.
