[Gender aspects of malnutrition and associated sequelae. Prevention and therapy]

Malnutrition is related to a range of secondary complications. The prevalence of many of these sequelae is higher in elderly women than in men, thus resulting in a higher level of impairment and reduced quality of life. Multiple factors lead to the development of malnutrition and socioeconomic causes, such as poverty among the elderly and isolation, are more common in elderly women. The age-associated loss of muscle mass is more pronounced in women than in men and the risk of developing sarcopenia and frailty is increased. The prevalence of sarcopenic obesity is higher in women than in men. Malnutrition increases the risk of osteoporosis and about 80 % of all osteoporosis patients are women. Furthermore, low serum levels of vitamin D correlate more closely to a poorer cognitive outcome in elderly women than they do in men. The prevention, early diagnosis and therapy of malnutrition is of great clinical importance, particularly to preserve physical functional capacity and thus quality of life in elderly women.
