Sarcopenia and Women Health in the Elderly

Dear Colleagues,

Sarcopenia is an important health problem that reduces quality of life and increases medical expenses in the elderly due to decreased exercise capacity, decreased physical function, increased risk of falls and fractures, decreased ability to perform daily activities, and increased risk of death. It has been reported that the presence of sarcopenia affects muscle protein dynamics, oxidative capacity, increases body fat mass, and more than doubles the risk of abdominal obesity, diabetes, dyslipidemia, hypertension, metabolic syndrome, and cardiovascular disease. Muscle mass decreases by 1-2% every year after the age of 40, and muscle strength by 1.5% every year, which accelerates after age 60. At age 80, about 50% is lost compared to age 30. This is especially true for women as estrogen plays an important role in maintaining muscle mass. Most of the studies analyzing the relationship between sarcopenia and dietary factors have been conducted on the elderly. However, age-related changes in body composition, such as loss of muscle mass and increase in body fat, begin during middle age and progress gradually. Also, after menopause, hormonal changes increase the risk of sarcopenia in women. Therefore, in this study, we analyzed dietary factors related to sarcopenia, a common disease in middle-aged and elderly women over the age of 50, who began senile sarcopenia. We identified a correlation with elevated risk of metabolic disease.
