*3.7.3 Number of abortions/miscarriage and type of delivery*

We also studied number of previous abortions/miscarriage and type of present delivery and tried to find out whether any correlation exists between the two or not. It was discovered that in women who had no history of abortion/miscarriage, 54.44% had normal delivery and 44.97% and 0.59% had caesarean section and forcep type of delivery respectively. In woman having 1 abortion/miscarriage, 47.73% had normal delivery, 47.7 had caesarean section and 4.4% had forcep delivery. And in women who had more than 2 abortions/miscarriage, 38.46% had normal delivery and 61.54% had caesarean section delivery (**Figure 11**).

#### **3.8 Prevalance of stress**

Current study showed that in underweight subjects, 50% had no stress at all. 34.09% had one type of stress. 13.64% had two types of stress and 2.27% had any 3 type of stress. In normal BMI women, 72.26% had no stress, 20.44%, 4.38% and *Association of Pre-Pregnancy Body Mass Index and Gestational Weight Gain with Preterm… DOI: http://dx.doi.org/10.5772/intechopen.96922*

2.92% had one type, two type and three type of stress respectively. In overweight women, 70% were stress free, 20% had one type and 10% had two types of stress. And in obese population, 33.33% had no stress, 40% had one type and 26.67% had two types of stress. The subjects having any 1 type of stress (physical, occupational, social, financial or pregnancy related) were more in underweight (34.09%) and obese (40%) class. The study revealed that in all BMI ranges, except obese, maximum subjects had no stress at all; whether physical or mental (**Figure 12**).

#### **3.9 Dietary Information**

#### *3.9.1 Milk and infant birth weight*

The study revealed that in women, who had consumed no milk during gestational period, 20.59% had LBW infant, 73.53% had normal and 5.88% had HBW infant. In subjects who occasionally had milk, 30.77% had LBW infant and 69.23% had normal infant birth weight. In women who had 1 glass milk daily, the incidence of LBW infant was 20.62%, normal birth weight was 75.26% and HBW was 4.12%. The mothers who drank 2 glass of milk, LBW, normal and HBW percentage was

found to be 20.25%, 77.22% and 2.53% respectively, while mothers who drank 3 glasses of milk, 33.33% were having LBW infant and 66.67% had normal infant weight. It was observed that the chances of LBW infant was less in women who had 1 or 2 glass of milk compared to them who had no milk or occasionally had milk (**Figure 13**).
