Abstract
Older adults are vulnerable to nutrition-related health problems due to health and psychosocial changes that accompany aging. Those in rural communities face additional problems. This study characterizes the nutritional risk of rural older adults using the Nutritional Risk Index (NRI), paying particular attention to gender differences in risk. Data come from face-to-face interviews with a random sample of 638 White rural adults aged 55 and older. Women scored significantly higher on the NRI, indicating greater nutritional risk. Women were more likely to report NRI items related to oral health, special diets, disease interference with eating, gastrointestinal problems, and anemia, whereas men were more likely to report smoking regularly. A comparison with the application of the NRI in other populations indicates that it is sensitive to nutrition-related health conditions that may be more prevalent in rural populations, making it a useful tool for measuring nutritional risk.

Naidoo I, Charlton KE, Esterhuizen TM, Cassim B. High risk of malnutrition associated with depressive symptoms in older South Africans living in KwaZulu-Natal, South Africa: a cross-sectional survey. JOURNAL OF HEALTH, POPULATION, AND NUTRITION 2015; 33:19. [PMID: 26825267 PMCID: PMC5026002 DOI: 10.1186/s41043-015-0030-0] [Citation(s) in RCA: 40] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/15/2015] [Accepted: 10/02/2015] [Indexed: 06/05/2023]
Abstract
BACKGROUND Malnutrition contributes to functional and cognitive decline in older adults, which results in decreased quality of life and loss of independence. This study aimed to identify determinants of nutritional risk among community-dwelling adults in KwaZulu-Natal, South Africa. METHODS A cross-sectional survey was undertaken in 1008 subjects aged 60 years and over who were randomly selected by systematic sampling. Demographics, socioeconomic data and self-reported history of medical conditions were recorded. The Mini Nutritional Assessment-Short Form (MNA-SF) was used to screen for nutritional risk, and the Centre for Epidemiologic Studies Depression scale was administered to all subjects. Descriptive statistics and the Pearson chi-square and Kruskal-Wallis tests were used for statistical analysis. Logistic regression modelling determined predictors of nutritional risk. RESULTS Of the 984 participants (mean age = 68.8 ± 7.4 years; range 60-103 years) who completed the MNA-SF, 51% were classified as having a normal nutritional status, 43.4% at risk for malnutrition and 5.5% classified as malnourished. Men were more likely to be either at risk for malnutrition or be malnourished than women (p = 0.008), as were subjects with a monthly household income of ≤R1600 per month (~133 USD) (p = 0.003). In logistic regression models, depressed people were 2.803 (p < 0.001) times more likely to be at risk or be malnourished than those not depressed. CONCLUSION A high prevalence of risk of malnutrition was identified in older South Africans living in an urban area with poor infrastructure. Further investigations are warranted to determine whether the higher prevalence of depressive symptomatology in nutritionally at risk individuals is a determinant or a consequence of malnutrition, in order to develop targeted nutritional interventions in this age group.

A randomized controlled trial of a theoretically-based behavioral nutrition intervention for community elders: lessons learned from the Behavioral Nutrition Intervention for Community Elders Study.

Abstract
Older adults with multiple comorbidities are often undernourished or at high risk for becoming so, especially after a recent hospitalization. Randomized controlled trials of effective, innovative interventions are needed to support evidence-based approaches for solving nutritional problems in this population. Self-management approaches where participants select their own behavioral goals can enhance success of interventions. The purpose of this study was to evaluate the feasibility and efficacy of a multilevel self-management intervention to improve nutritional status in a group of high-risk older adults. The Behavioral Nutrition Intervention for Community Elders (B-NICE) trial used a prospective randomized controlled design to determine whether the intervention, compared to standard care, maintained or increased caloric intake (depending on baseline body mass index) and, consequently, stabilized or increased body weight. Participants were 34 Medicare-eligible, age 65 years old or older, homebound adults who were consuming insufficient calories and/or had a history of weight loss ≥2.5% over 6 months. The intervention took place within participants' homes. Outcome measures, including energy intake (based on collection of three 24-hour dietary recalls) and body weights were assessed at baseline and at 60 days post randomization. The primary analyses included analyses of covariance and Pearson's χ(2). We hypothesized that the intervention would result in increased caloric intake and weight gain in underweight older adults and increased or stabilized caloric intake and weight for everyone else. The intervention was feasible; however, it did not result in differences between groups for desired outcomes of either caloric intake or body weight. Future interventions might either deliberately involve caregivers or reduce burden for both patients and caregivers.

Abstract
Unintentional weight loss and Undernutrition are major problems among older people living in Long-Term Care Facilities (LTCF). Undernutrition manifests in LTCF particularly as weight loss and low Body Mass Index (BMI) and is associated with increased morbidity and mortality as well as with functional decline. There are many factors associated with poor nutritional status and affecting protein-energy intake and/or energy expenditure. These include age of 85 years or older, low nutrient intake, loss of ability to eat independently, swallowing and chewing difficulties, becoming bed-ridden, pressure ulcers, history of hip fracture, dementia, depressive symptoms and suffering from two or more chronic illnesses. Nutritional evaluation is an essential part of the Comprehensive Geriatric Assessment (CGA). This evaluation ranges from methods such as BMI to several validated tools such as Mini-Nutritional Assessment (MNA). After diagnosis, the management of undernutrition in LTCF requires a multidisciplinary approach which may involve dietary and environmental improvements and managing multiple co-morbidities, while avoiding polypharmacy as far as possible. Finally, the need for supplementation or artificial (tube) feeding may be considered taking into account the CGA and individual needs. This document presents a succinct review and recommendations of evaluation and treatment of undernutrition.

Abstract
PURPOSE The measurement of prescription medication use is usually through a simple count of medications, which tends to ignore therapeutic categories. This research investigated prescription medication use among homebound older adults, by documenting the therapeutic prescription medication categories used by these individuals and identifying the factors associated with use of multiple therapeutic categories. METHODS Baseline Nutrition and Function Study (2000-2001) data from 326 homebound older persons who completed the medication review component (visual inspection of medications) of the baseline in-home interview and used > or =1 prescribed medication were included in this analysis. RESULTS More than 40% (n = 133) regularly took medications from three to four different therapeutic categories and 31.6% (n = 103) used > or =5 different therapeutic categories. The use of respiratory medications declined with increasing age, and more women than men used diuretic and thyroid replacement medications. Independent of other factors, increased use of multiple therapeutic categories was associated with sociodemographic characteristics (gender, age, living arrangement, marital status and medication coverage), medical conditions (diabetes, heart problems and lung disease) and inability to self-manage medications. CONCLUSIONS Our findings suggest that individual characteristics and medical conditions may help identify homebound elders at high risk for using prescription medications from an increased number of different therapeutic categories. This observation may help clinicians and community-based providers of services to older persons to be aware of differences in therapeutic medication use within an older population, and how patterns of use may alter service needs.

Abstract
BACKGROUND Ensuring nutritional health for elders has been shown to reduce healthcare costs and enhance quality of life. Studies, however, have shown that malnutrition is present in 2% to 51% of community-dwelling elders, depending on the definition used and the population studied. An empirically tested framework for studying nutritional health in community-dwelling elders is not yet available. OBJECTIVE To test the goodness-of-fit exhibited by the framework of nutritional health among community-dwelling elders based on the Roy Adaptation Model using structural equation modeling (SEM). METHODS A population-based study investigated 243 elders dwelling in public housing. Demographics, polypharmacy, chronic illness, oral health, depressive symptoms, functional status, and satisfaction with social support were assessed to test their relation with nutritional health according to the propositions of the Roy Adaptation Model and scientific evidence. RESULTS The SEM analysis indicated that functional status, oral health, depressive symptoms, and satisfaction with social support affect nutritional health directly. Oral health, depressive symptoms, functional status, and satisfaction with support mediated the effects of age, ethnicity, education, and number of medications and chronic illnesses on nutritional health. The model accounted for 35% of the variance in nutritional health and demonstrated a good fit with the data and with the values for Bentler's Comparative Fit Index (0.94) and chi (1.76). CONCLUSIONS The propositions of the Roy Adaptation Model were supported, and the findings showed that this framework of nutritional health among community-dwelling elders could serve as a theoretical and empirical base for future inquiry.

Abstract
This review focuses on the interactions between nutritional status and drugs in frail elderly persons. Impairment of nutritional status, a component of clinical presentation in the frail elderly, has a major impact on the pharmacology of many drugs devolving from the physiological alterations it generates. Food itself plays a central role in nutritional status and in possible interactions with drugs. Conversely, drugs have often, directly and indirectly, a deleterious effect on the nutritional state of the elderly. However, research in this domain is scarce, and future clinical studies will need to include more elderly and frail elderly individuals, to help clinicians to better understand these interactions.

Abstract
A dieta influencia todos os estágios do ciclo da vida, fornecendo nutrientes necessários ao sustento do corpo humano. Alterações de ordem funcional e/ou estrutural, provocadas por doenças e infecções agudas ou crônicas, levam à utilização de medicamentos, cujo objetivo é restaurar a saúde. A via preferencial escolhida para a sua administração é a oral, entre outras razões, por sua comodidade e segurança. O fenômeno de interação fármaco-nutriente pode surgir antes ou durante a absorção gastrintestinal, durante a distribuição e armazenamento nos tecidos, no processo de biotransformação ou mesmo durante a excreção. Assim, é de importância fundamental conhecer os fármacos cuja velocidade de absorção e/ou quantidade absorvida podem ser afetadas na presença de alimentos, bem como aqueles que não são afetados. Por outro lado, muitos deles, incluindo antibióticos, antiácidos e laxativos podem causar má absorção de nutrientes. Portanto, o objetivo do presente artigo é apresentar uma revisão dos diversos aspectos envolvidos na interação fármaco-nutriente.

Abstract
Statistics abound demonstrating the aging of the population, and this comes as no news to physicians caring for an increasing number of elderly patients. This group experiences the expected age-related physiologic declines, including systems critical to integrative functions such as immunologic, neurologic, and metabolic systems. Although an increased prevalence of several common gastrointestinal disorders occurs in the elderly person, aging per se appears to have less direct effect on most gastrointestinal functions, in large part because of the functional reserve of the gastrointestinal tract. Although irritable bowel symptoms decrease with aging, there seems to be an increase in many gastrointestinal disorders of function and motility. The gastroenterologist will frequently encounter elderly patients with complaints of dysphagia, anorexia, dyspepsia, and disorders of colonic function. Understanding age-related changes in gastrointestinal physiology and effects of common comorbid illnesses enhances the ability to evaluate and treat these common, troublesome symptoms.

Abstract
Both undernutrition and overnutrition contribute to increased risk of morbidity and mortality. Marasmus, kwashiorkor, and decreased micronutrient status are types of nutritional deficiencies, whereas obesity and problems resulting from dietary supplements are examples of overnutrition. Screening for malnutrition can be performed in the ambulatory, hospital, and institutional populations, each with methods appropriate for the target population. For patients determined to be at high risk, further nutrition assessment can be performed to help arrive at specific nutritional treatment goals. Identifying and treating malnutrition can potentially have an important impact on decreasing morbidity and mortality in the population.

Abstract
Nutrition status plays a significant role in a drug's pharmacodynamics. Some disease states and other special conditions affect nutrient status and a drug's therapeutic efficacy. Many classes of drugs, including antimicrobials, hypoglycemics, and hypocholesterolemic agents, can be affected by the presence of food, with the geriatric patient particularly at risk. While a drug's pharmacokinetic profile can usually be predicted, it can be modified by nutrients and by certain pathophysiologic conditions, including aging, hepatic dysfunction, and micronutrients.

Abstract
Older patients' nutritional status must be assessed for their morbidity and mortality to be decreased and their quality of life improved. Food and fluid intake is markedly influenced by oral health status. In turn, oral health has an interrelationship with general health. Because nutritional status and oral health exist in a symbiotic relationship, it is essential that the dental team identify older patients who are nutritionally at risk. Screening for nutritional problems in elderly dental patients is made easier with screening instruments developed by the Nutrition Screening Initiative (NSI). The NSI developed criteria to determine risk factors for poor nutritional status in older Americans. The DETERMINE Your Nutritional Health checklist, a 10-item screening instrument, followed by the Levels I and II Nutrition Screens, can be used in the dental office to ascertain which elderly patients are most likely to be in danger of experiencing nutritional problems. The dental team can then perform interventions and/or make appropriate referrals.
