Design outcomes

Primary

Measure	Time frame	Description
Gestational weight gain	16 weeks gestation, 35 weeks gestation	Rate of gestational weight gain will be computed as difference between weights measured at study entry and gestational week 35; this difference will be divided by the number of weeks of observation during pregnancy (i.e., weeks between study entry and final pregnancy assessment). If gestational week 35 is unavailable, most proximal clinic visit weight will be used.

Secondary

Measure	Time frame	Description
Partner's weight loss	study entry, when pregnant partner reaches 35 weeks gestation	Weight lost by the non-pregnant partner during the study will be assessed by subtracting their weight at the 35 week gestation visit from their study entry weight.
