Induced at 39 weeks?

Ei
Any of you ladies been told that it's better to induce at 39 weeks? I was recently told that at my last doctors appointments. Said there's a study that says that women who are morbidly obese benefit from not going full term. I'm considered high risk due to my BMI (270 lbs prepregnancy and 45 BMI). No gestational diabetes and have only gained 2 lbs the entire pregnancy which I'm at 29 weeks and 3 days. Just curious to see if anyone has gotten that.
