[Postpartum body weight change]

Area of Science:

• Reproductive Health
• Maternal Nutrition
• Postpartum Recovery

Context:

• Maternal weight changes after childbirth are a significant public health concern.
• Understanding the long-term effects of pregnancy on body weight is crucial for women's health.
• Previous research has explored various factors influencing postpartum weight, but a comprehensive analysis of pre-pregnancy BMI and gestational weight gain is needed.

Purpose:

• To investigate maternal body weight development one year after pregnancy.
• To determine the impact of pre-pregnancy nutritional status and gestational weight gain on postpartum weight change.
• To analyze the relationship between pre-pregnancy body mass index (BMI) categories and weight retention.

Summary:

• A prospective cohort study of 486 women examined postpartum weight changes at 3, 6, and 12 months.
• Results indicated a mean weight gain of 1.0 ± 3.6 kg after one year, with 53.7% gaining 0-5 kg.
• Higher gestational weight gain (highest quartile) was significantly associated with greater postpartum weight retention (p < 0.001).

Impact:

• Pregnancy is identified as a risk factor for postpartum weight retention.
• Pre-pregnancy body weight and prenatal weight gain are significant contributors to postpartum weight changes.
• Findings highlight the importance of monitoring maternal weight and providing guidance on appropriate gestational weight gain.
