Although the association between air pollution and health has been studied, no study has examined its variation by ethnic groups in Europe and UK. Innovative methods that reveal the spatial-temporal dimension of this association are also lacking. This study investigates the effect of air pollution on self-reported general health and mental well-being in the UK by ethnicity using data from the “UK Household Longitudinal: Understanding the Society” panel survey. Individual-level health data were linked to air pollution data (NO2, SO2, PM10, PM2.5) at the local authority level. Multilevel mixed-effects linear models were used to investigate the relationship between air pollution and general health and mental well-being. Increasing concentrations of NO2, SO2, PM10, and PM2.5 pollutants were associated with poorer health and well-being. Decomposing air pollution into between-within (spatial-temporal) effects showed a strong between-spatial effect of air pollution on general health and mental well-being; yet no significant within-temporal effects were detected. Analysis by ethnicity revealed poorer self-reported health among Indians, Pakistani/Bangladeshi, and Black/African/Caribbean in comparison to the British-white and among non-UK born individuals with increasing concentrations of air pollution. However, no significant differences were noted between ethnic minorities and British-White for the effect of air pollution on mental well-being with exception for the Pakistani/Bangladeshi who showed poorer mental well-being with higher levels of air pollution. Using longitudinal individual and contextual-level linked data, this study shows the deteriorating effect of air pollution on individuals’ general health and mental well-being, which is more pronounced for ethnic minorities in the UK.
