PubHealth.info® (a subsidiary of PakMed) presents scientific information mainly based on abstracts of articles published on a variety of public health issues/topics, particularly encompassing population planning, disease prevention, maternal and child health, and communicable and non-communicable diseases (like HIV AIDS, malaria, etc) that are affecting a significant portion of population in developing and developed countries. Here you can find abstracts of articles published on a variety of public health topics under category "Contraception (Birth Control) and Family Planning". Contraception (birth control) is a regimen of one or more actions, devices, or medications followed in order to deliberately prevent or reduce the likelihood of a woman becoming pregnant or giving birth. Therefore contraception is the utilization of various and sundry surgical procedures, devices, practices, agents, or drugs with the intention of preventing conception or impregnation (pregnancy). Methods and intentions typically termed birth control may be considered a pivotal ingredient to family planning. Birth control is a controversial political and ethical issue in many cultures and religions, and although it is generally less controversial than abortion specifically.

ABSTRACT

The objective was to estimate the effect of body mass index (BMI) and weight on risk of pregnancy while using oral

contraceptives (OCs). We conducted a case-control study of 248 health maintenance organization enrollees who

became pregnant while using OCs between 1998 and 2001 and 533 age-matched enrollees who were nonpregnant

OC users during the same period. Using logistic regression we calculated adjusted odds ratios (ORs) to estimate the

risk of pregnancy according to BMI and weight quartile. Among all OC users, when compared with women having a

BMI of 27.3 or less, the risk of pregnancy was nearly 60% higher in women with BMI greater than 27.3 (OR 1.58, 95%

confidence interval _CI_ 1.11-2.24) and over 70% higher in women with BMI greater than 32.2 (OR 1.72, 95% CI 1.04 -

2.82). Among consistent users (women who missed no pills in reference month), the risk of pregnancy was more than

doubled in women with BMI greater than 27.3 (OR 2.17, 95% CI 1.38 -3.41) or BMI greater than 32.2 (OR 2.22, 95% CI

1.18-4.20). When compared with women weighing 74.8 kg or less, among consistent OC users the risk of pregnancy

was over 70% higher in women weighing more than 74.8 kg (OR 1.71, 95% CI 1.08 -2.71) and nearly doubled in

women weighing more than 86.2 kg (OR 1.95, 95% CI 1.06 -3.67). Our results suggest that being overweight may

increase the risk of becoming pregnant while using OCs. If causal, this association translates to an additional 2-4

pregnancies per 100 woman-years of use among overweight women, for whom consideration of additional or effective

alternative contraceptive methods may be warranted. (PubHealth.info Document ID: CONT1T 75-06)
