The Claim

In obese pregnant women, each one-centimeter increase in neck circumference during early pregnancy is associated with an 11% higher risk of developing gestational diabetes, indicating that upper-body subcutaneous fat may serve as a clinically useful metabolic risk indicator independent of BMI.

In plain English

In obese women during early pregnancy, a larger neck circumference is linked to a higher chance of developing gestational diabetes, and this measurement may provide useful metabolic risk information beyond what BMI shows.

See the scientific wording

Neck circumference in early pregnancy is associated with a 11% increased risk of gestational diabetes per centimeter increase in obese women, suggesting upper-body subcutaneous fat may be a clinically useful indicator of metabolic risk beyond BMI.

Why this might work

Extra fat around the neck and upper body releases chemicals that block insulin from working properly, and spills fat into the blood, which overwhelms the liver and muscles, making them unable to respond to insulin properly.

1 study
  1. Study: Gestational diabetes in women with obesity; an analysis of clinical history and simple clinical/anthropometric measures

    In obese pregnant women, those with thicker necks early in pregnancy were more likely to develop gestational diabetes — so neck size might be a simple way to spot who’s at higher risk, even better than just looking at overall weight.
