The patients had significantly lower bone mineral density (BMD) in L3 and L2\u20104 than controls. However, there was no difference in whole\u2010body BMD. L3 and L2\u20104 BMD was positively correlated with body weight and was negatively correlated with duration of illness and amenorrhea. Patients who had been more active 6 months before the time of the study had significantly higher L3 BMD than the less active patients. Most patients had an abnormally low serum estrogen level, whereas the mean serum levels of thyroid hormone (T<jats:sub>3<\/jats:sub>, T<jats:sub>4<\/jats:sub>), cortisol, calcitonin, parathyroid hormone and vitamin D were within the normal range. No correlation was found between L3 or L2\u20104 BMD and the levels of these hormones. These results suggest that severe weight loss, low physical activity, longer duration of amenorrhea and deficiency of estrogen contribute to bone loss in patients with anorexia nervosa, whereas calcium\u2010regulating hormones such as parathyroid hormone, calcitonin and vitamin D are unlikely to be a primary contributor to bone loss.<\/jats:p>","DOI":"10.1111\/j.1600-0447.1992.tb03280.x","type":"journal-article","created":{"date-parts":[[2007,8,23]],"date-time":"2007-08-23T12:35:49Z","timestamp":1187872549000},"page":"358-363","source":"Crossref","is-referenced-by-count":41,"title":["Reduced
