  1. The coefficients in columns 1, 3, and 5 present the estimated effect of the variable listed to the left on percentile BMI. The coefficients in columns 2, 4, and 6 present the estimated effect of ln MWH on the the variable listed to the left. Each coefficient comes from a separate regression. OLS estimation is used in all regressions except when the dependent variable is the number of meals (poisson estimation is used in this case) or breastfed or received allowance (probit is used in these cases). Marginal effects are reported in all columns. Robust standard errors are in parentheses. + significant at 10%; * significant at 5%; ** significant at 1%
