Evaluate the Changes of Body Mass Index and Blood Pressure in Combined Oral Contraceptive Pill Users

The oral contraceptive pill, 'the pill', was introduced in the starting of the 1960s. Presently, worldwide about 100 million women are current users of combined hormonal contraceptives (COC) most frequently used in the western world. The most frequently used agents are a combination of drugs containing both the estrogen and progesterone. This combination is considered to be highly efficacious, generally considered 99.9% and a use effectiveness of 97.0% to 98.0%. This study was done to evaluate the changes of Body Mass Index (BMI) and Blood pressure ( BP) in combined oral contraceptive pill users in comparison to non- users. This cross sectional study was carried out in the Department of Physiology, Mymensingh Medical College, Mymensingh, Bangladesh from July 2021 to June 2022. Total number of 120 reproductive aged women, age ranged from 15-55 years was included in this study. Among them, sixty (60) combined oral contraceptive pill users subjects were taken as study group (Group II) and sixty (60) age matched oral pill non users subjects were taken as control group (Group I). Data were expressed as mean±SD and statistical significance of difference among the group was calculated by unpaired students' 't' test and Pearson's correlation coefficient test. The mean±SD of BMI of control group (Group I) and study group (Group II) were 22.50±1.50 kg/m² and 27.64±1.28 kg/m² respectively. In study group (Group II) BMI was increased. Result is statistically highly significant (p<0.001). The mean±SD of systolic blood pressure of control group (Group I) and study group (Group II) were 111.17±8.51 mm of Hg and 127.50±6.14 mm of Hg respectively. In this study the mean±SD of diastolic blood pressure of control group (Group I and study group (Group II) were 75.58±5.05mm of Hg and 87.00±4.89 mm of Hg respectively. In study group (Group II) diastolic blood pressure was increased. Result is statistically highly significant (p<0.001). So the assessment of this parameter is important for early detection and prevention of complication related to combined oral contraceptive pill use for leading a healthy life.
