Pathological fear of food12/14/2022 ![]() Large longitudinal studies such as the National Health and Nutrition Examination Surveys (NHANES) and the Baltimore Longitudinal Study have shown a critical decline of weight and energy intake with aging, leading to “anorexia of aging” as the most common eating disturbance in the elderly. It involves physiological, psychological, social and economic factors, often summarized using the acronym the “nine d’s” comprising dementia, dysgeusia, dysphagia, diarrhea, depression, disease (acute, chronic), poor dentition, dysfunction (functional disability), and drugs. ![]() The etiology of malnutrition appears to be complex and multifactorial. Despite the availability of various nutrition assessment tools, less than 40% of malnutrition cases are identified upon hospital admission. Its prevalence is reported to range between 5–10% among community-dwelling older adults, compared to 30–61% among hospitalized elderly patients, and 12–85% among residents of long-term and subacute care facilities. ![]() Īlthough there have been no uniformly established diagnostic criteria for malnutrition, clinicians and researchers have relied on anthropometric measures, biochemical markers and specific screening tools to identify patients suffering from malnutrition. #Pathological fear of food free#Malnutrition can be defined as “a state resulting from lack of intake or uptake of nutrition that leads to altered body composition (decreased fat free mass) and body cell mass, leading to diminished physical and mental function and impaired clinical outcome from disease”. With population aging, eating disturbances and malnutrition have increasingly become an important health issue to address. In the United States, the prevalence of adults aged 65 years and above increased from 36.6 million in 2005 to 47.8 million in 2015 (a 30% increase) and is predicted to more than double by 2060, reaching around 98 million. Given the increase in life expectancy, older adults have become a rapidly growing portion of the world’s population. Nutrition is one of the most important determinants of physical and mental health, and plays a key role in successful aging. ![]()
