Figure 1

Secular trends and annual mean birth weight of neonates born to mothers with high and low educational attainment, 1996–2013. The Fig. 1 shows the secular trends and annual mean birthweight of neonates born to mothers with high and low educational attainment in Brazilian state capitals from 1996 to 2013. In this figure, the curves of the mean weight of newborns born to mothers with high (“Mean_high”) and low (“Mean_low”) education are presented, as well as the secular trends of average weight of newborns born to mothers with discharge (“Jp high”) and low (“Jp low”) education, assessed through Joinpoint Regression. Each of these curves has different outlines and colors marked each year. It is possible to observe that the mean birth weight among neonates born to mothers with high educational attainment declined steadily throughout the study period, while remaining stable among infants born to mothers with low schooling, with only a slight increase from 2005 onward.
