AIM AND METHOD: Based on the systematic analyses of a 10-year period at the Institute of Forensic Medicine at the University Clinic Hamburg-Eppendorf, the frequency of underweight in elderly persons at their time of death was retrospectively calculated. Body mass index (BMI) values <20 kg/m(2) were taken as indicative of underweight and the data of 1,551 women and 2,270 men, mean age 69 years (51-101 years) were analyzed. RESULTS: The prevalence of underweight was 15.4%. Low BMI values were more frequent in women than men (18.8 vs. 13.1%) and more frequent in persons needing professional nursing care at the time of death (28.9%). Underweight increased for the age range 70-79 from about 15% to over 38% for those 90 years and older at the time of death. Pressure sores were documented in 1.8% of cases. Persons in need of professional nursing care more often had pressure sores at their time of death. Furthermore, pressure sores were observed more often in underweight elderly in need of professional nursing care. CONCLUSION: Underweight at the time of death is observed more often in the very old. This is associated with the need for professional nursing care and also the occurrence of pressure sores. Less than 5% of persons with tumors were included. The results underscore the need of early detection of people at risk of malnutrition when growing older.
