Abstract
BACKGROUND
Inappropriate weight gain during pregnancy may present risks for maternal and newborn health. Pregnancy is considered the optimal time to intervene on women's health behaviors such as eating habits and physical activity. However, current clinical practice guidelines for weight management during pregnancy were not fully based on randomized trials, thus lacking specific "active intervention ingredients" that are proven effective in achieving appropriate gestational weight gain. Therefore it is essential to develop and implement an evidence-based weight management program for pregnant women.
OBJECTIVE
To examine the effects of a midwife-led weight management program on improving appropriate gestational weight gain, health literacy, experience of antenatal care, and maternal and neonatal outcomes among Chinese pregnant women.
DESIGN
A two-group randomized controlled trial.
SETTINGS AND PARTICIPANTS
A total of 426 pregnant women were recruited from a tertiary women's hospital in eastern China.
METHODS
Participants were randomly allocated to either intervention group (n = 213) or control group (n = 213). Women in the intervention group participated in a midwife-led weight management program during pregnancy, while women in the control group received the conventional obstetrician-led antenatal care. We assessed women at the first antenatal contact, 35-36 weeks gestation and 2-3 days postpartum. Data on gestational weight gain, health literacy, experience of antenatal care, and maternal and neonatal outcomes were compared between the two groups. Dummy variable analysis was conducted to reveal the effect of weight management program on gestational weight gain.
RESULTS
The overall gestational weight gain between the two groups was not statistically different (t = -1.377, P = 0.170). Compared with women in the control group, the odds of having inappropriate gestational weight gain was lower in the intervention group (OR = 0.270, 95%CI 0.169, 0.431). Further subgroup analyses showed that women in the intervention group had lower risk of inadequate gestational weight gain (OR = 0.305, 95%CI 0.180, 0.515) and excessive gestational weight gain (OR = 0.236, 95%CI 0.138, 0.404) than those in the control group. The score of experience of antenatal care was significantly higher in the midwife-led weight management group than that in the control group (193.70 ± 18.51 versus 165.70 ± 28.23, P < 0.001). Women's health literacy score was higher in the intervention group than control group [74.41 (69.57, 81.77) versus 71.88 (66.23, 77.18), P = 0.004].
CONCLUSION
Compared with the conventional antenatal care, the midwife-led weight management program could facilitate appropriate gestational weight gain, enhance health literacy, and promote positive experience of antenatal care for Chinese pregnant women.
