The table presents OLS and mother fixed effects estimates for the relationship between maternal mental health and our birth outcomes (PT, LBW, SGA) using the SOEP sample. OLS estimates are based on a full information sample of all individuals. Mother fixed effects models are based on the whole sample of mothers with at least two children, without conditioning on full information for all control variables and excluding all pregnancies with multiple births. In the OLS model with controls, we include the mother´s age at birth (and squared), maternal smoking before birth, average working hours of the mother before birth, marital status, education and migration background of the mother, homeownership, household size and income before birth, an indicator for previous preterm births, twin and multiple births, the presence of older siblings, the sex of the child and year and region fixed effects. The mother fixed effects model with controls includes the sex of the child as an indicator for previous preterm birth and one for the presence of an older sibling. Robust standard errors in parentheses.
