Social deprivation and adverse perinatal outcomes among Western and non-Western pregnant women in a Dutch urban population

► We use a composite multidimensional variable indicating neighbourhood social quality (Social Index). ► We take into account clustering of individuals within neighbourhoods by using a multilevel approach. ► Our results demonstrate a more profound effect of social deprivation on adverse perinatal outcomes in Western women. ► Implications concern general policies, and targeted policies which differ for Western and non-Western women.
