Evidence suggests that infants born to women who use
smokeless tobacco in pregnancy have a higher risk of several adverse outcomes such as
stillbirth, preterm birth, and low birth weight. Additionally, maternal exposure to secondhand smoke (SHS) in pregnancy has also been associated with a modest reduction in birth weight, and can increase the risk of low birth weight (<2500 g) by 22%.
A healthy body mass index (BMI) risk category is 18.5 to 24.9. When people get to a BMI of 25 to 29.9, they are considered overweight. A BMI of 30 and above is in the obese category, with 35 and above being degrees of obesity. Forty and above is extreme, or morbid, obesity
