Summary
This study defines optimal gestational weight gain (GWG) for Singaporean women. Lower GWG is recommended for heavier women, but optimal ranges differ from existing guidelines for underweight and obese individuals.
Area of Science:
- Obstetrics and Gynecology
- Maternal-Fetal Medicine
- Public Health Nutrition
Background:
- Gestational weight gain (GWG) significantly impacts maternal and infant outcomes.
- Existing guidelines may not fully capture the needs of diverse ethnic populations.
- Defining optimal GWG is crucial for personalized prenatal care.
Purpose of the Study:
- To establish population-specific optimal gestational weight gain (GWG) recommendations for the multiethnic Singaporean population.
- To analyze the relationship between GWG, pre-pregnancy BMI, and composite perinatal outcomes.
- To compare findings with existing Institute of Medicine (IOM) guidelines.
Main Methods:
- Analysis of data from 1529 live singleton deliveries.
- Multinomial logistic regression to identify GWG associated with lowest composite perinatal risk.
- Stratification by Asia-specific body mass index (BMI) categories.
Main Results:
- Optimal GWG varied significantly by pre-pregnancy BMI category.
- Recommended GWG: 19.5 kg (underweight), 13.7 kg (normal), 7.9 kg (overweight), 1.8 kg (obese).
- Optimal ranges for underweight and obese women fell outside IOM recommendations.
Conclusions:
- The study provides the first optimal GWG data for the Singaporean population.
- Findings support lower GWG for heavier pre-pregnancy BMI Asian women, aligning partially with IOM.
- Optimal GWG for underweight and obese Singaporean women requires adjusted recommendations.

In the United States, obesity is a prominent concern. It is linked to heightened mortality rates due to increased occurrences of conditions such as hypertension, atherosclerosis, coronary artery disease, and diabetes compared to nonobese individuals. A patient is classified as obese if their actual body weight surpasses the ideal or desirable body weight by 20%, based on Metropolitan Life Insurance Company data. Ideal body weights consider average weights and heights for males and females...

6.3K
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

4.9K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...
