Long-term mortality in anorexia nervosa: a report after an 8-year follow-up and a review of the most recent literature

Abstract

Objective: To evaluate long-term mortality rate of anorexia nervosa (AN) patients in a southern Italy population compared to the most recent literature. Design: Retrospective and review setting. Patients and interventions: One hundred and forty-seven female AN patients, consecutively admitted from 1994 to 1997 to the Outpatient Unit, were re-examined between June and November 2003. Our data are compared with 10 other studies published since 1988. Results: One hundred and twenty-three deaths in 2240 patients, amounting to a total mortality rate of 5.25% were reported in the literature. Deaths due to suicide, AN-related and AN-unrelated diseases were 1.20, 3.07 and 0.98%, respectively. After correcting for unrelated deaths, mortality rate was 4.27%. In our 8-year follow-up, we found a mortality rate of 2.72% (1.82% after correcting for unrelated deaths). Standardized mortality ratio was 9.7. Conclusion: We interpret our favourable findings as a consequence of an integrated, clinical-nutritional and psychiatric approach. Finally, considering AN demographic characteristics, that is young female subjects in Westernized societies, mortality rate is confirmed to be dramatically high.

Anorexia induced by activation of serotonin 5-HT 4 receptors is mediated by increases in CART in the nucleus accumbens

“…We hypothesized that anorexia may involve altered signaling events within the nucleus accumbens (NAc), a brain structure involved in reward. We show here that direct stimulation of serotonin ( A norexia nervosa is one of the mental diseases exhibiting the highest mortality rates in industrialized countries (1,2). No effective strategies for treating this disorder are available.…”

Academy for eating disorders position paper: Eating disorders are serious mental illnesses

“…Standardized mortality rates in AN are the highest of any psychiatric disorder [99][100][101][102][103][104][105][106] and are 12 times higher than the annual death rate from all causes in females 15-24 years of age. 106,107 Mortality rates for BN and EDNOS are harder to determine, being partially complicated by the relatively high degree of ''cross-over'' diagnoses from EDNOS and BN to AN and vice versa. 108 However, current estimates suggest that mortality rates in BN may not be elevated or only slightly elevated.…”

Cultural Factors in Collegiate Eating Disorder Pathology: When Family Culture Clashes With Individual Culture

“…Further, we concurrently assessed the strength of each individual's interdependence and independence, respectively, and compared this to their levels of enmeshment and eating disorder pathology. This second analysis was important for two 2 reasons. First, our research was conducted with ethnic minorities living in the United States, and thus to assume all Asian Americans, for example, to be interdependent might be incorrect.…”

“…1 This higher prevalence is of particular concern because eating disorders are among the most lethal mental disorders, with mortality rates from anorexia nervosa, for example, exceeding 4 to 5%. 2 Concurrently, college student populations are becoming increasingly ethnically diverse and multicultural. 3 Cultural issues and how they relate to health are emerging as important issues to study in this increasingly diverse climate.…”
