Abstract Background We aimed to assess which sociodemographic factors are associated with current asthma and indicators of lung function in 10‐year‐old children. Methods analysed data 5237 children (Mean age: 9.7, SD: 0.3) from the Generation R Study (2012‐2016), a population‐based cohort study Netherlands. Indicators included parental educational level, net household income, financial difficulties, employment status child ethnic background. Current (yes/no) was defined as ever doctor‐diagnosed‐asthma combined wheezing symptoms or asthma‐medication use past 12 months. Lung measured by spirometry forced expiratory volume 1 second (FEV ), vital capacity (FVC), FEV /FVC, flow after exhaling 75% FVC (FEF 75 ). Within‐study sex‐, height‐ age‐adjusted measurements’ z‐scores were converted. Results After adjustment for all factors, an independent association observed between background function. Compared Dutch background, nonwestern had higher odds having (OR: 1.61, 95% CI: 1.02, 2.53), lower z‐score (−0.25, −0.35, −0.14), /FVC (0.26, 0.14, 0.37) FEF (0.15, 0.04, 0.25). Conclusions Among children, adjusting wide range factors. No associations found socioeconomic asthma. Explanations these such language barriers, suboptimal care pathophysiological differences require further investigation.
