BackgroundPrevalence of overweight and obesity is rising. Hence, it is likely that a higher proportion of women undergoing assisted reproduction treatment are overweight or obese.MethodsIn a retrospective cross-sectional analysis using routinely collected data of an IVF Unit and maternity hospital in a tertiary care setting in the UK, direct costs were assessed for all weight classes. Costs for underweight, overweight and obese were compared with those for women with normal body mass index (BMI).ResultsOf 1756 women, who underwent their first cycle of IVF between 1997 and 2006, 43 (2.4%) were underweight; 988 (56.3%) had normal BMI; 491 (28.0%) were overweight; 148 (8.4%) were obese (class I) and 86 (4.9%) were obese (class II). The mean (95% CI) cost of each live birth resulting from IVF was pound 18,747 (13 864-27 361) in underweight group; pound 16,497 (15 374-17 817) in women with normal BMI; pound 18,575 (16,648-21,081) in overweight women; pound 18,805 (15 397-23 554) in obese class I; pound 20,282 (15 288-28 424) in obese class II or over.ConclusionsThe cost of a live birth resulting from IVF is not different in underweight, overweight and obese class I when compared with women with normal BMI. However, due to increased obstetric complications weight loss should still be recommended prior to commencing IVF even in overweight or obese (class I) women.
