---|---|---|---|---|
Primary | Weight Gain Per Week of Observation | 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. | 13 weeks gestation, 35 weeks gestation | |
Secondary | Offspring Weight Gain | Offspring weight for age z scores from birth (1 week), to 6 months, and 12 months of age. | 1 week, 6 months, 12 months | |
Secondary | Kcals/Day | Changes in maternal calorie intake (Kcal/day) | 13 weeks gestation, 34 weeks gestation | |
Secondary | Changes in Offspring Dietary Intake | Changes in offspring intake of breast milk (#feeds per day) and/or formula (#feeds per day). | 1 week, 6 months, 12 months | |
Secondary | Changes in Maternal Glucose | Fasting glucose | 13 weeks gestation, 34 weeks gestation | |
Secondary | Number of Women Exceeding IOM Guidelines as a Proportion of Total Number of Women in Each Group. | Self-reported pre-pregnancy weight will be subtracted from weight measured at last clinic visit prior to delivery. Women will be categorized as exceeding 2009 IOM guidelines if the difference is > 11.5 kg gain for women with prepregnancy overweight or >9 kg for women with prepregnancy obesity. | 13 weeks, 40 weeks | |
Secondary | Number of Women at or Below Prepregnancy Weight as a Proportion of the Total Number of Participants in Each Group | Weight measured at 48-56 weeks postpartum and subtracted from self-reported prepregnancy weight and then categorized as at or below vs. above self-reported prepregnancy weight. | 48-56 weeks post delivery |
