10.22376/ijpbs.2019.10.1.p1-12 Volume 8 Issue 1 2017 (January - March) This study is done to evaluate the awareness of consuming caffeine among pregnant women.Caffeine crosses the placenta and reaches to the baby. Although the mother can be able to handle the amounts of caffeine taken but the baby cannot. The baby's metabolism is still maturing and cannot fully metabolize the caffeine. Any small amount of caffeine can also cause changes in baby's sleep pattern or normal movement pattern in the later stages of pregnancy. Remember, caffeine is a stimulant and can keep both mother and baby awake. This study is done with the help of questionnaire based survey.300 pregnant women participated in this survey and the questionnaire was circulated manually and through online. The data was clubbed and the final results were obtained by using the spss software version 9.0.Caffeine is a stimulant and a diuretic. Because caffeine is a stimulant, it increases the mother's blood pressure and heart rate, both of which are not recommended during pregnancy. Thus study aims to create awareness among pregnant women about consuming caffeine.Pregnant women were unaware about the side effects of consuming caffeine during pregnancy and so an awareness and full knowledge was provided to the women through this survey.
