What can we learn about eating disorder mortality from eating disorder diagnoses at initial assessment? A Danish...

Increased risk for premature mortality is well established for women and girls diagnosed with anorexia nervosa (AN), but less is known for other types of eating disorder (ED), and especially the mortality outcome for boys and men is under-studied. In this registry-based observational epidemiological study, we included all people appearing in the Danish Psychiatric Central Research Register with an eating disorder (ED) diagnosis in the time period from Jan 1,1970 to Dec 31, 2014 (N: 22,633). For each patient four controls without ED were selected, matched for age, sex and place of residence (N: 90486). In all 802 people with ED died over 255762.6 person-years of observation. Standardized mortality ratio (SMR) for all-cause mortality and suicide mortality was significantly increased for all ED-diagnoses in women. The SMRs for men were similar, but only reached significance for the diagnoses AN and unspecified ED. Mortality by natural causes and accidents was significantly increased in most ED-diagnoses in women. The unequal female-to-male ratio in this, and most other studies of ED-patients, suggests that boys and men with ED have unmet needs.
