Secular trends in gestational weight gain and parity on birth weight: An editorial.

Bohn et al. also confirmed that GWG is associated with BW and that being a second- or third- or later-born child implicates an impact on BW beyond the effect of maternal weight gain.

Finally, Bohn et al.1 concluded that "birth order must be considered a potential risk factor for higher BW, and that maternal pregnancy weight gain is not the driving factor for higher BW in siblings". They concluded that "birth order must be considered a potential risk factor for higher BW" and that "maternal pregnancy weight gain is not the driving factor for higher BW in siblings.".
