- Women with a history of bulimia nervosa hospitalisation have increased risk for cardiovascular disease (CVD) hospitalisation and death up to 8 years later.
Why this matters
- Women with this eating disorder might benefit from close management of CVD risk factors over the long term, in addition to managing the known acute risk.
- Follow-up totaled 2,957,677 person-years.
- Women with a bulimia nervosa hospitalisation history had a greater incidence of CVD vs women with pregnancy-related hospitalisation: 10.34 (95% CI, 7.77-13.76) vs 1.02 (95% CI, 0.99-1.06) per 1000 person-years.
- Having 3 or more admissions for bulimia was linked to greater long-term CVD incidence: 25.13 (95% CI, 13.52-46.70) per 1000 person-years.
- Compared with pregnancy-related hospitalization, with bulimia nervosa hospitalisation:
- CVD risk was 4.25-fold greater (95% CI, 2.98-6.07).
- Death risk was 4.72-fold greater (95% CI, 2.05-10.84).
- Bulimia nervosa hospitalisation was associated with increased risk for all CVDs examined.
- Longitudinal cohort study, Canada; 416,709 women (818 with bulimia nervosa hospitalisation; 415,891 with pregnancy-related event hospitalisation).
- Funding: Heart & Stroke Foundation of Canada; others.
- Misclassification possible.
