An interesting study just came out that puts first-born women in a very large seat. Large? Well, the study says that the likes of the first-born ladies are very much at risk to be obese or overweight compared to later-born siblings.
Researchers used the Swedish Birth Register for the data and analyzed 13,500 pairs of sisters. They looked on their baby weights and heights records as well as their weights and heights after their first pregnancy on their first prenatal check-up at around 10 to 12 weeks of gestation.
