Objective This paper aims to study long-term bone mineral development in former patients with an onset of anorexia nervosa during childhood and adolescence. Methods Bone mineral density (BMD) in lumbar spine and total hip was measured in 39 female participants (mean age = 23.1 years, SD 3.5) an average of 8.1 (±3.3) years after treatment start. Results At follow-up, seven participants (17.9%) still suffered from an eating disorder. Mean BMD in the former patients was within the normal range in the hip but significantly reduced in the spine. Fourteen (36%) of the participants had osteopenia, and three (8%) had osteoporosis in the spine and/or hip. Amenorrhea for more than two years was associated with reduced BMD in the spine, whereas low weight at follow-up was associated with low BMD in both the spine and the hip. Conclusion A large minority of these former patients had low bone mass in young adulthood. In accordance with other studies, our findings support the importance of weight restoration for future bone health in young patients with anorexia nervosa.

Background Although pregnancy can be associated with adaptive changes in weight and eating behaviour for women with eating disorders, less is known about whether these changes are maintained in the postpartum period. We used a longitudinal design to examine gestational and postpartum weight trajectories in mothers with and without eating disorders in the Norwegian Mother and Child Cohort Study (MoBa) conducted by the Norwegian Institute of Public Health. Methods Fifty-six women reported anorexia nervosa (AN), 636 bulimia nervosa, 3327 binge eating disorder and 69 eating disorder not otherwise specified, purging type. The referent group included 61 233 mothers with no eating disorder. We used a mixed effects model to predict weight change over time by eating disorder subtype. Results Mothers with AN, bulimia nervosa, binge eating disorder and eating disorder not otherwise specified had greater increases in body mass index (BMI) during pregnancy and greater decreases in BMI over the first 6 months postpartum. Women with AN shifted from the underweight BMI range before pregnancy to the normal weight range at 36 months postpartum Conclusions Patterns of maternal weight gain and retention during the perinatal period vary across eating disorder subtype and warrant clinical attention.
