In this sample, 23.9% of the women were overweight pregnancy; tobacco use (body mass index, BMI 25–29.9 kg/m2), and 12.5% were obese (BMI 30 kg/m2). Obese women exer- cised more and changed to healthy diets more frequently than normal-weight women (odds ratio 7.43; 95% confidence interval 3.7–14.9). Six out of ten women (n ¼ 266) took folic acid when they started trying to conceive, but 11% stopped taking folic acid after some time. Taking folic acid was associated with a higher level of education (p < 0.001). Conclusions: Among subfertile women, one-third were overweight or obese, and some had other life- style factors with known adverse effects on fertility such as use of tobacco. Overweight and obese women adjusted their habits but did not reduce their body mass index. Women of fertile age would benefit from preconception counseling, and the treatment of infertility should routinely offer interven- tions for lifestyle changes.
