Preventing Excessive Gestational Weight Gain in Obese Women
2021年7月29日 更新者:Suzanne Phelan、California Polytechnic State University-San Luis Obispo
The purpose of this study is to study the effects of a multicomponent lifestyle intervention that includes partial meal replacements as a means to prevent excessive gestational weight gain in obese women.
The primary hypothesis is that the intervention will reduce the rate of gestational weight gain compared with standard care.

主要结果指标
结果测量 |
措施说明 |
大体时间 |
|---|---|---|
|
Weight Gain Per Week of Observation
大体时间:13 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.

13 weeks gestation, 35 weeks gestation

Offspring Weight Gain
大体时间:1 week, 6 months, 12 months
|
Offspring weight for age z scores from birth (1 week), to 6 months, and 12 months of age.
|
1 week, 6 months, 12 months
|
|
Kcals/Day
大体时间:13 weeks gestation, 34 weeks gestation
|
Changes in maternal calorie intake (Kcal/day)
|
13 weeks gestation, 34 weeks gestation
|
|
Changes in Offspring Dietary Intake
大体时间:1 week, 6 months, 12 months
|
Changes in offspring intake of breast milk (#feeds per day) and/or formula (#feeds per day).
|
1 week, 6 months, 12 months
|
|
Changes in Maternal Glucose
大体时间:13 weeks gestation, 34 weeks gestation
|
Fasting glucose
|
13 weeks gestation, 34 weeks gestation
|
|
Number of Women Exceeding IOM Guidelines as a Proportion of Total Number of Women in Each Group.
大体时间:13 weeks, 40 weeks
|
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
|
|
Number of Women at or Below Prepregnancy Weight as a Proportion of the Total Number of Participants in Each Group
大体时间:48-56 weeks post delivery
|
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
