Brief Summary: **PURPOSE OF THE STUDY-**

Pregnancy is a physiological condition involving specific regulation of body weight. Maternal obesity and gestational weight gain that hasbecome more common nowadays lead to the poor obstetric outcome. Evidence from scientific studies shows the important role of physical activity in health promotion by improving quality of life and prevention and control of various diseases. Regular moderate physical activity may improve risk profiles in pregnant women. A few decades ago, pregnant women were advised to reduce their physical activities and even interrupt their occupational work especially in last trimester of pregnancy. However, since 1990, experts have admitted the positive effect of regular physical activity during pregnancy and encourage it, unless it is contraindicated. Maintaining light to moderate physical activity during an uncomplicated pregnancy provides various benefits for womenâ€˜s health like a decrease in gestational diabetes mellitus, decrease in weight gain, less fluid retention, decrease in the incidence of gestational hypertension and cardio-vascular stress and thrombosis. It also increases the chance of onset of spontaneous labor andnormal vaginal delivery and reduces the rate of Cesarean delivery. Also, physical activity helps to make women self-confident and reduce the risk of post-partum depression.

However, some studies show that strenuous physical activity during pregnancy is associated with increased risk of abortions and premature delivery. Considering the persistent controversies on the above topic, the current study aims to find the association between physical activity during pregnancy and occurrence of adverse maternal and child health outcome.

**AIM:**To study the effect of physical activity on adverse pregnancy outcomes.

**OBJECTIVES-**To study the profile of physical activity in pregnancy.

To compare the risk of adverse pregnancy outcomes in the sedentary group and physically active group.

**SAMPLE SIZE**-

1. We estimated the sample size anticipating 92% confidence interval 3% error margin accounting for 20% attrition and dropouts.

**Sample size (n)=Z(1-alpha/2)2 pq/d2**

P= anticipated proportion=8%( Vigorously active pregnant women.)

q=1-p

d=3% , precision

Z(1-alpha/2)= 1.96

Alpha=5%, level of significance

So the sample size is 393.

**METHODS:**

All women who deliver in Dr. T.M.A Pai hospital Udupi and fulfill the inclusion criteria will be included in the study.

Physical activity questionnaire prepared according to activities of Indian women in this region by an expert group. A questionnaire including household activities, workplace activities and exercise during pregnancy in a 1 st, 2nd and 3rd trimester. The intensity of physical activity will be calculated by WHO MET scores scale. Based on the MET scores, women will be divided into the sedentary, moderately active and h highly active group.

The profile of physical activity in pregnancy and its effect on pregnancy(GDM, Hypertension, Preterm birth, IUGR)in different groups and mode of delivery (LSCS/NVD/INDUCED NVD/ SPONTANEOUS NVD/INSTRUMENTAL ) will be studied.
