A total of 1256 mother\u2013child pairs were analysed. Placental inflammation and oxidative stress biomarkers mRNA expression were tested using real-time quantitative PCR. Outdoor time was measured annually from 4 to 7 years. Children underwent cycloplegic refraction and ocular biometry to obtain spherical equivalent (SE) and axial length at 7\u20138 years. Binary logistic regression, generalised linear and Quantile g-Computation models were used to examine the associations.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Among the children, 306 (24.4%) children were myopic. Each unit increase in monocyte chemoattractant protein-1 was correlated to a 1.6% higher risk of myopia (OR=1.016, p=0.025), 0.008 D lower SE (\u03b2=\u22120.008, p=0.024) and a 0.006\u2009mm elongation in AL (\u03b2=0.006, p=0.014). Each unit elevate in interleukin-4 increased SE by 0.003 D (\u03b2=0.003, p=0.043) and decreased AL by 0.003\u2009mm (\u03b2=\u22120.003, p=0.017), with similar trends in outdoor time declining trajectory. However, all associations were not significant after false discovery rate adjustment. Furthermore, each unit increase in the mixed exposure of oxidative stress was associated with a 0.070\u20130.074 D reduction in SE.<\/jats:p>\n                  <\/jats:sec>\n
