Which group of women may experience lower effectiveness rates with hormonal methods of birth control?

Question

Quizplus · Accepted Answer

Women who are significantly overweight may experience lower effectiveness rates with hormonal methods of birth control. This is because the hormones may be less effective in preventing ovulation in women with higher body mass indexes (BMIs). Women in other age groups or who exercise too much are not necessarily at higher risk for decreased effectiveness with hormonal birth control. Women over 35 may be at higher risk for certain health complications with hormonal birth control, but this does not necessarily impact effectiveness. Similarly, while there may be other factors that can impact effectiveness rates, age alone (such as in the 15-19 age group) does not appear to be a significant factor.
