Effect of participation in congregate-site meal programs on nutritional status of the healthy elderly

The Health and Well-being Impacts of Community Shared Meal Programs for Older Populations: A Scoping Review

Background and Objectives

There are social and economic benefits to supporting individuals to live independently for as long as possible. Structured shared meal programs provide opportunities for older individuals to connect in their communities and likely impact their health and well-being. Research in this area has not been summarized in recent years. This scoping review was undertaken to explore the impact shared meal programs may have for older community-dwelling adults.

Research Design and Methods

Nine databases were systematically searched in 2020, and 5,996 unique studies were identified. Two independent reviewers screened titles, abstracts, and full text for inclusion. Reference lists of included papers were hand searched, and the search was updated in 2021. Eighteen studies were included in the final review.

Results

Studies were published between 1980 and 2021 and most were published in the United States. Most studies were cross-sectional, two adopted a qualitative design, one a cohort design. Significant associations were reported between shared meal programs and improved dietary intake; however, minimal improvements were reported for physical health measures. The programs had a positive impact on attendees' social networks and perceived well-being.

Discussion and Implications

Structured shared meal programs show promise in supporting the health and well-being of older adults in the community. They provide additional nutrition, opportunities for social connection, and are perceived to contribute to perceived well-being. More investigation is required to understand how these programs work to facilitate health and well-being, and how they can best be used to improve health outcomes for older populations.

Dietary advice with or without oral nutritional supplements for disease-related malnutrition in adults

BACKGROUND

Disease-related malnutrition has been reported in 10% to 55% of people in hospital and the community and is associated with significant health and social-care costs. Dietary advice (DA) encouraging consumption of energy- and nutrient-rich foods rather than oral nutritional supplements (ONS) may be an initial treatment.

OBJECTIVES

To examine evidence that DA with/without ONS in adults with disease-related malnutrition improves survival, weight, anthropometry and quality of life (QoL).

SEARCH METHODS

We identified relevant publications from comprehensive electronic database searches and handsearching. Last search: 01 March 2021.

SELECTION CRITERIA

Randomised controlled trials (RCTs) of DA with/without ONS in adults with disease-related malnutrition in any healthcare setting compared with no advice, ONS or DA alone.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed study eligibility, risk of bias, extracted data and graded evidence.

MAIN RESULTS

We included 94, mostly parallel, RCTs (102 comparisons; 10,284 adults) across many conditions possibly explaining the high heterogeneity.  Participants were mostly older people in hospital, residential care and the community, with limited reporting on their sex. Studies lasted from one month to 6.5 years.  DA versus no advice - 24 RCTs (3523 participants) Most outcomes had low-certainty evidence. There may be little or no effect on mortality after three months, RR 0.87 (95% confidence interval (CI) 0.26 to 2.96), or at later time points. We had no three-month data, but advice may make little or no difference to hospitalisations, or days in hospital after four to six months and up to 12 months. A similar effect was seen for complications at up to three months, MD 0.00 (95% CI -0.32 to 0.32) and between four and six months. Advice may improve weight after three months, MD 0.97 kg (95% CI 0.06 to 1.87) continuing at four to six months and up to 12 months; and may result in a greater gain in fat-free mass (FFM) after 12 months, but not earlier. It may also improve global QoL at up to three months, MD 3.30 (95% CI 1.47 to 5.13), but not later. DA versus ONS - 12 RCTs (852 participants) All outcomes had low-certainty evidence. There may be little or no effect on mortality after three months, RR 0.66 (95% CI 0.34 to 1.26), or at later time points. Either intervention may make little or no difference to hospitalisations at three months, RR 0.36 (95% CI 0.04 to 3.24), but ONS may reduce hospitalisations up to six months. There was little or no difference between groups in weight change at three months, MD -0.14 kg (95% CI -2.01 to 1.74), or between four to six months. Advice (one study) may lead to better global QoL scores but only after 12 months. No study reported days in hospital, complications or FFM. DA versus DA plus ONS - 22 RCTs (1286 participants) Most outcomes had low-certainty evidence. There may be little or no effect on mortality after three months, RR 0.92 (95% CI 0.47 to 1.80) or at later time points. At three months advice may lead to fewer hospitalisations, RR 1.70 (95% CI 1.04 to 2.77), but not at up to six months. There may be little or no effect on length of hospital stay at up to three months, MD -1.07 (95% CI -4.10 to 1.97). At three months DA plus ONS may lead to fewer complications, RR 0.75 (95% CI o.56 to 0.99); greater weight gain, MD 1.15 kg (95% CI 0.42 to 1.87); and better global QoL scores, MD 0.33 (95% CI 0.09 to 0.57), but this was not seen at other time points. There was no effect on FFM at three months. DA plus ONS if required versus no advice or ONS - 31 RCTs (3308 participants) Evidence was moderate- to low-certainty. There may be little or no effect on mortality at three months, RR 0.82 (95% CI 0.58 to 1.16) or at later time points. Similarly, little or no effect on hospitalisations at three months, RR 0.83 (95% CI 0.59 to 1.15), at four to six months and up to 12 months; on days in hospital at three months, MD -0.12 (95% CI -2.48 to 2.25) or for complications at any time point. At three months, advice plus ONS probably improve weight, MD 1.25 kg (95% CI 0.73 to 1.76) and may improve FFM, 0.82 (95% CI 0.35 to 1.29), but these effects were not seen later. There may be little or no effect of either intervention on global QoL scores at three months, but advice plus ONS may improve scores at up to 12 months. DA plus ONS versus no advice or ONS - 13 RCTs (1315 participants) Evidence was low- to very low-certainty. There may be little or no effect on mortality after three months, RR 0.91 (95% CI 0.55 to 1.52) or at later time points. No study reported hospitalisations and there may be little or no effect on days in hospital after three months, MD -1.81 (95% CI -3.65 to 0.04) or six months. Advice plus ONS may lead to fewer complications up to three months, MD 0.42 (95% CI 0.20 to 0.89) (one study). Interventions may make little or no difference to weight at three months, MD 1.08 kg (95% CI -0.17 to 2.33); however, advice plus ONS may improve weight at four to six months and up to 12 months. Interventions may make little or no difference in FFM or global QoL scores at any time point.

AUTHORS' CONCLUSIONS

We found no evidence of an effect of any intervention on mortality. There may be weight gain with DA and with DA plus ONS in the short term, but the benefits of DA when compared with ONS are uncertain. The size and direction of effect and the length of intervention and follow-up required for benefits to emerge were inconsistent for all other outcomes.  There were too few data for many outcomes to allow meaningful conclusions. Studies focusing on both patient-centred and healthcare outcomes are needed to address the questions in this review.

The impact of home-delivered meal services on the nutritional intake of community living older adults: a systematic literature review

BACKGROUND

There is a global increase in populations aged over 65 years. Physiological changes that occur during ageing may increase the nutritional risk for older adults. To avoid malnutrition and address some of the barriers to obtain an adequate food supply, home-delivered meals services provide meals in the home or in congregate settings for older adults who require nutritional support.

METHODS

This systematic literature review explored whether nutritional intake is improved in community-living older adults when receiving meal services compared to when meal services are not received. Four electronic databases were searched up to 31 January 2019. In total, 13 original studies were included in this analysis with the components: intervention of home-delivered meal or congregate meal services to older adults; comparison with groups not receiving meal services or days not receiving the meal service; and nutritional intake as an outcome measured by food history, dietary recall and/or food frequency questionnaire.

RESULTS

The results supported a beneficial effect of home-delivered meals on dietary intake of energy, protein and/or certain micronutrients in older adults.

CONCLUSIONS

The increased total energy intake is a positive influence on malnutrition risk in frail older adults and the increased protein intake supports good health, promotes recovery from illness and assists in maintaining functionality in older adults. Additionally, there was a particular increase in calcium intake, which is relevant in ageing, especially for bone health.

Development and Evaluation of Let's Do Lunch: A Congregate Meal Program at an Urban Senior Center

A mixed-methods needs assessment was conducted in an urban senior center serving lower-income seniors in Toronto, Ontario, to determine whether they should offer a congregate meal program. Methods included three focus groups with participants (n = 31), a focus group with staff (n = 8), a center-wide survey (n = 36), and a community scan of programs in the area. Interviews with five coordinators at other seniors' centers who offered meal programs were also used to gauge interest and assist with program development. The results of these activities supported offering a twice weekly lunch program with user fees. Over a 6-month pilot period, process evaluation was conducted, comprising observations, record review, and focus groups with participants (n = 9) and staff/volunteers (n = 7) to examine delivery, usage, and costs. Results indicated that the program was well-received and affordable, and that demands on staff were reasonable when a facilitator with culinary training was available. The lessons learned can be used to guide other senior centers in developing and evaluating congregate meal programs.

Sustaining Our Nation's Seniors through Federal Food and Nutrition Programs

Food insecurity is a pressing issue in the United States where one in six people suffer from hunger. The older adult population faces unique challenges to receiving adequate nutrition. The federal government currently employs four food and nutrition programs that target the senior population in an effort to address their specific needs. These are the Congregate Meals and Home Delivered Meals Programs (provided through the Older Americans Act), and the Senior Farmers' Market Nutrition Program and Child and Adult Care Food Program (provided by the United States Department of Agriculture). As the older adult population continues to grow, it will be important to evaluate and improve these programs and the social policies related to them. This manuscript describes each policy in depth, considers economic and political elements that have shaped each policy, describes the level of program success, and offers suggestions for future research and program development.

Depression as a correlate of functional status of community-dwelling older adults: utilizing a short-version of 5-item Geriatric Depression Scale as a screening tool

Depression has been known to be associated with functional limitations in elderly populations and screening is an effective preventive approach. The purpose of this study was to examine the contribution of depression in explaining the functional status of community-dwelling older adults and to explore the utility of a short version 5-item Geriatric Depression Scale (GDS-5) as a screening tool.

DESIGN

Cross-sectional survey Settings: Six hospitals and communities served by home-delivery meal programs Participants: 529 individuals aged 60 years and older.

MEASUREMENTS

Using structured survey questionnaires, key variables including demographics, depression status, and two domains of functional status assessed by basic Activities of Daily Living (ADL) /Instrumental ADL (IADL) and mini-mental status (MMSE) were collected. To determine the unique contribution of depression in explaining functional status of participating older adults, hierarchical multiple regression was conducted.

RESULTS

The model explained 18 % of the total variance in physical function and 21 % of the total variance in cognitive function. Race/ethnicity and depression were significant predictors of functional status. In particular, entry of the depression variable resulted in a significant R square change of 7%, accounting for a unique portion of the ADL/IADL variance. In terms of cognitive function measured by MMSE, entry of the depression variable showed a small, but significant change. Older adults who were ethnic minorities and had depression were significantly more likely to report poor perceived physical and cognitive function. Hierarchical multiple regressions revealed that some personal factors such as age, education, race/ethnicity contributed to the explanatory model, and depressive symptoms significantly explained additional variance. GDS-5 was less reliable (Cronbach's alpha= 0.5) to assess depressive symptoms in this study.

CONCLUSION

Depression was a significant contributing factor to functional limitations of older adults. A short 5-item version of the GDS could be used to screen older adults, but two-tiered GDS-5/15 would be better alternative tool.

Dietary advice with or without oral nutritional supplements for disease-related malnutrition in adults

BACKGROUND

Disease-related malnutrition has been reported in 10% to 55% of people in hospital and the community. Dietary advice encouraging the use of energy- and nutrient-rich foods rather than oral nutritional supplements has been suggested as the initial approach for managing disease-related malnutrition.

OBJECTIVES

To examine evidence that dietary advice in adults with disease-related malnutrition improves survival, weight and anthropometry; to estimate the size of any additional effect of nutritional supplements combined with dietary advice and to compare the effects of dietary advice with oral nutritional supplements.

SEARCH STRATEGY

Relevant publications were identified from comprehensive electronic database searches and handsearching.Last search: 14 February 2010.

SELECTION CRITERIA

Randomised controlled trials of dietary advice with or without oral nutritional supplements in people with disease-related malnutrition in any health-care setting compared with no advice, oral nutritional supplements or dietary advice given alone.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed trial eligibility, risk of bias and extracted data.

MAIN RESULTS

Forty-five studies (3186 participants) met the inclusion criteria; (dietary advice compared with: no advice (1053 participants); with oral nutritional supplements (332 participants); with dietary advice and oral nutritional supplements (731 participants); and dietary advice plus oral nutritional supplements compared with no additional intervention (1070 participants). Follow-up ranged from 18 days to 24 months. No comparison showed a significant difference between groups for mortality or morbidity. There was a significant change in weight found between groups when comparing dietary advice to no advice for interventions lasting greater than 12 months, mean difference 3.75 kg (95% confidence interval 0.97 to 6.53), and when all studies were combined, mean difference 1.47 kg (95% confidence interval 0.32 to 2.61) although there was significant heterogeneity in the combined analysis (I(2) = 90%). Similar improvements in weight were found for the comparison of dietary advice with nutritional supplements if required versus no advice, mean difference 2.20 kg (95% confidence interval 1.16 to 3.25). Dietary advice compared with no advice was also associated with significantly improved mid-arm muscle circumference when all studies were combined, but with moderate heterogeneity, mean difference 0.81 mm (95% confidence interval 0.31 to 1.31). Dietary advice given with nutritional supplements compared with dietary advice alone resulted in improvements in: mid-arm muscle circumference, mean difference -0.89 mm (95% confidence interval -1.35 to -0.43); triceps skinfold thickness, mean difference -1.22 mm (95% confidence interval -2.34 to -0.09); and grip strength, mean difference -1.67 kg (95% confidence interval -2.96 to -0.37), although the effects on triceps skinfold thickness and grip strength were heterogeneous. Dietary advice with supplements if required resulted in a significant increase in triceps skinfold thickness compared with no advice, mean difference 0.40 mm (95% confidence interval 0.10 to 0.70), although these results are from a single trial with only 29 participants.

AUTHORS' CONCLUSIONS

Evidence of variable quality suggests that dietary advice with or without oral nutritional supplements may improve weight, body composition and grip strength. We found no evidence of benefit of dietary advice or oral nutritional supplements given alone or in combination on survival. Studies addressing the impact of nutritional interventions on nutritional, functional and patient-centred outcomes are needed.

Physical activity, energy requirements, and adequacy of dietary intakes of older persons in a rural Filipino community

Background

Aging is a process associated with physiological changes such as in body composition, energy expenditure and physical activity. Data on energy and nutrient intake adequacy among elderly is important for disease prevention, health maintenance and program development.

Methods

This descriptive cross-sectional study was designed to determine the energy requirements and adequacy of energy and nutrient intakes of older persons living in private households in a rural Filipino community. Study participants were generally-healthy, ambulatory, and community living elderly aged 60–100 y (n = 98), 88 of whom provided dietary information in three nonconsecutive 24-hour food-recall interviews.

Results

There was a decrease in both physical activity and food intake with increasing years. Based on total energy expenditure and controlling for age, gender and socio-economic status, the average energy requirement for near-old (≥ 60 to < 65 y) males was 2074 kcal/d, with lower requirements, 1919 and 1699 kcal/d for the young-old (≥ 65 to < 75 y) and the old-old (≥ 75 y), respectively. Among females, the average energy requirements for the 3 age categories were 1712, 1662, and 1398 kcal/d, respectively. Actual energy intakes, however, were only ~65% adequate for all subjects as compared to energy expenditure. Protein, fat, and micronutrients (vitamins A and C, thiamin, riboflavin, iron and calcium) intakes were only ~24–51% of the recommended daily intake. Among this population, there was a weight decrease of 100 g (p = 0.012) and a BMI decrease of 0.04 kg/m² (p = 0.003) for every 1% decrease in total caloric intake as percentage of the total energy expenditure requirements.

Conclusion

These community living elderly suffer from lack of both macronutrient intake as compared with energy requirements, and micronutrient intake as compared with the standard dietary recommendations. Their energy intakes are ~65% of the amounts required based on their total energy expenditure. Though their intakes decrease with increasing age, so do their energy expenditure, making their relative insufficiency of food intake stable with age.

Dietary advice for illness-related malnutrition in adults

BACKGROUND

Illness-related malnutrition has been reported in 10% to 55% of ill people in hospital and the community in areas of food sufficiency. Dietary advice encouraging the use of energy- and nutrient-rich foods rather than oral nutritional supplements has been suggested for managing illness-related malnutrition.

OBJECTIVES

To examine evidence that dietary advice to improve nutritional intake in adults with illness-related malnutrition improves survival, weight and anthropometry; to estimate the size of any additional effect of nutritional supplements given in combination with dietary advice.

SEARCH STRATEGY

Relevant publications were identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings. Additional studies were sought by contacting dietitians, clinicians and the manufacturers of nutritional supplements. Last search: September 2007

SELECTION CRITERIA

Randomised controlled trials of dietary advice in people with illness-related malnutrition compared with:(1) no advice;(2) oral nutritional supplements; and(3) dietary advice plus oral nutritional supplements.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed trial eligibility, methodological quality and extracted data.

MAIN RESULTS

Thirty-six studies (37 comparisons) met the inclusion criteria with 2714 randomised participants. Twelve trials (comparing dietary advice plus supplements if required with no advice) identified during searching are included as a separate comparison. Follow up ranged from 18 days to 24 months. No comparison showed a significant difference in mortality. There are several significant results for change in weight and other nutritional indices favouring nutritional intervention, but the precise contributions of the different strategies have yet to be determined. It is uncertain whether nutritional supplements and dietary advice produce the same effects. There was insufficient evidence to draw conclusions about clinical outcomes and cost. Few data were available for other outcomes.

AUTHORS' CONCLUSIONS

This review highlights the lack of evidence for the provision of dietary advice in managing illness-related malnutrition. Dietary advice plus nutritional supplements may be more effective than dietary advice alone or no advice in enhancing short-term weight gain, but whether this is sustainable, or whether survival and morbidity are improved remains uncertain. A large adequately-powered randomised controlled trial is needed comparing the efficacy of different therapies to increase dietary intake in people with illness-related malnutrition and examining the impact of this on clinical function and survival.

Nutrition Risk and Associated Factors in Congregate Meal Participants in Northern Florida

Nutrition is a key for extending quality of life of the elderly. Factors associated with nutritional risk in elders were identified with a modified nutrition screen initiative checklist. High, moderate and low nutritional risk was seen in 31, 46 and 23%, respectively, of 324 elders in six congregate meal sites in northern Florida. High nutritional risk was associated with urban residency, females, being African American, self-reported poor health and irregular visits to medical/health professionals. African American females living in urban areas with limited access to health care are most vulnerable.

Reaching Out to Racial/Ethnic Minority Older Persons for Elderly Nutrition Programs

This paper reports findings from a study that was conducted to identify perceived barriers to racial/ethnic minority elders' participation in an elderly nutrition program (ENP) in a large metropolitan area and effective strategies for reaching out to them. The data were collected from a survey with the ENP's staff and volunteers and three focus group discussions with professionals working with minority elders and minority community leaders. The study participants identified as their perceived barriers: the lack of information or misinformation; culturally driven reluctance to ask for outside help; fear and distrust of formal systems; lack of ethnic menus in the program; discomfort due to cultural differences; and inaccessibility and inadequacy of transportation. Recommended outreach strategies included: involvement of family members in the information dissemination process; establishment of good working relationships with community leaders and contact with key older persons; diversification of menus and increased use of food enhancements; increase in cultural activities/programs in congregate dining centers; solicitation of input from current participants; provision of intergenerational programs; recruitment of volunteer drivers from the minority community; location of the program in ethnic enclaves or places where minority elders can easily congregate; and improvement in transportation services.

Nutritional and health consequences are associated with food insecurity among U.S. elderly persons

The purpose of this study was to examine the consequences associated with food insecurity for the nutritional and health status of the elderly in the United STATES: The data analyzed were from the Third National Health and Nutrition Examination Survey (1988-1994) and the Nutrition Survey of the Elderly in New York State (1994). Multiple logistic and linear regression analyses were used to assess the extent to which food-insecure elderly were likely to have lower nutrient intake, skinfold thickness, self-reported health status and higher nutritional risk. Regardless of food insecurity status, older people consumed less than the recommended dietary allowance for eight nutrients. Food-insecure elderly persons had significantly lower intakes of energy, protein, carbohydrate, saturated fat, niacin, riboflavin, vitamins B-6 and B-12, magnesium, iron and zinc, as well as lower skinfold thickness. In addition, food-insecure elderly persons were 2.33 (95% confidence interval: 1.73-3.14) times more likely to report fair/poor health status and had higher nutritional risk. These results indicate that food-insecure elderly persons have poorer dietary intake, nutritional status and health status than do food-secure elderly persons. It is necessary to ensure the nutritional well-being of all elderly persons who are at nutritional and health risk, including those who are food insecure and have even poorer nutritional and health status than those who are food secure.

Understanding needs is important for assessing the impact of food assistance program participation on nutritional and health status in U.S. elderly persons

This study aimed to assess the impact of food assistance programs on nutritional and health status of nutritionally needy elderly persons. Two cross-sectional and one longitudinal data sets were used: Third National Health and Nutrition Examination Survey (1988-94), Nutrition Survey of the Elderly in New York State (1994) and Longitudinal Study of Aging (1984-1990). Multiple logistic and linear regression analyses were used to examine whether food assistance participants among food insecure elderly (i.e., those whose needs for food assistance programs are met) have better nutrient intake, skinfold thickness and self-reported health status and less nutritional risk, hospitalization and mortality than nonparticipants (i.e., those whose needs are unmet) and whether the benefit is larger than that among food secure elderly persons. Across three data sets, food insecure elderly persons had poorer nutritional and health status than food secure elderly persons. Contrary to the hypotheses, among food insecure elderly persons, food assistance participants had similar or poorer nutrient intakes, skinfold thickness, nutritional risk, self-reported health status, hospitalization and mortality than nonparticipants. Food secure participants had similar nutritional and health status as food secure nonparticipants. Lack of information on the dynamic nature and changes in needs with program participation in the three data sets likely did not allow accurate estimation of the impact of food assistance participation. Different study designs, as well as theory and knowledge of needs that clarifies need status and its change within each older individual across an appropriate time interval, are necessary to accurately assess impacts of food assistance programs.

Older adults need guidance to meet nutritional recommendations

OBJECTIVE

The purpose of this study was to compare the diet of healthy, free-living senior volunteers to the dietary reference intakes (DRIs) and Food Guide Pyramid recommendations.

METHODS

This study was a cross-sectional assessment of dietary habits, as measured using a standardized food frequency questionnaire, among 1,740 healthy Southwestern U.S. adults, aged 51 to 85 years. Assessment of independently-living volunteers to chemoprevention trials provides an efficient mechanism to profile typical dietary habits among the older adult population.

RESULTS

Daily estimated macronutrient intakes exceeded recommended proportions of protein and fat. In contrast, more than 60% of this senior population reported dietary vitamin D, vitamin E, folate and calcium intakes below estimated average requirements (EAR). Based on the Food Guide Pyramid recommendations, fewer than 10% of the older adults consumed the recommended daily dairy and grain servings. More females than males consumed recommended vegetable (49% versus 40%) and fruit (53% versus 48%) servings (p < 0.05). More males consumed recommended grain (11% versus 7%) and protein (78% versus 73%) servings (p < 0.05) than females.

CONCLUSIONS

Mean micronutrient intakes compared well with DRIs, although fewer than one-half of these older adults consumed recommended levels for vitamin D, vitamin E, folate, and calcium or daily food servings of dairy, grains, vegetables or fruits. Since the beneficial aspects of foods are not limited to essential nutrients, nutrition recommendations to older adults may be improved by emphasizing daily servings of nutrient-dense choices within the Food Pyramid.

"Outings to your taste": a nutrition program for the elderly

"Outings to Your Taste" is an innovative program that aims to improve the nutritional status and social network of elderly people who receive home-delivered meals. This article examines participation in one of the program's components, outings to community restaurants. Participation data were collected on-site and information about client characteristics was collected in at-home interview surveys of targeted clients (n = 144). While about half of the clients had tried at least one outing, more than 25% of them participated in at least one third of the outings offered to them. Results indicate that the program attracted a variety of clients in terms of sociodemographic, health, and social isolation characteristics.

Nutrition and health status assessment of community-residing elderly in New York City: a pilot study

Ninety-five percent of persons over the age of 65 years live in the community and benefit from community-based health and nutrition services. The purpose of this project was to evaluate diet, function, and mental health in 40 men and women aged 65 years and older who were residing in a large metropolitan community. Nutritional status was assessed using two 24-hour recalls, 5 days of food records, a food frequency, and anthropometric measurements. Participants responded to standardized activities of daily living and instrumental activities of daily living instruments and an investigator-developed, performance-based appraisal of food preparation and management. Cognition and mood were assessed using the Folstein Mini-Mental Examination and the Yesavage Depression Scale. The nutrient intakes for individuals were compared with the Recommended Dietary Allowances (RDAs) and the Food Guide Pyramid. Mean energy intake was 1,625 kcal (range = 787 to 2,910 kcal); 7 persons consumed more than 2,000 kcal. The mean vitamin and mineral intake for participants met the RDAs except for calcium, vitamin D, zinc, and magnesium intakes. The average percentages of carbohydrate, protein, and fat were 53%, 16%, and 30%, respectively. Nutritional assessments of subjects with and without congregate meals were contrasted. Six of the 13 congregate-meal participants were at nutritional risk, compared with 6 of 27 not receiving congregate meals. The interrelationships of diet, functional status, and mental health factors were examined along with recommendations for future data collection in similar studies.

Comparative evaluation of body composition in medically stable elderly

OBJECTIVE

Accurate assessment is needed to identify the nutritional status of elderly persons. Anthropometric data were collected to describe body composition of the sample, including blacks and whites aged 55 to 89 years, and to explore the usefulness of several methods of body composition measurement.

DESIGN

Baseline measurements were made as part of a longitudinal study. Body composition variables, particularly lean and lean-to-height measures, were used.

SUBJECTS/SETTING

One hundred twenty-nine free-living medically stable elderly at senior community centers were self-selected into the study.

STATISTICAL ANALYSIS

Descriptive statistics were generated for all variable by gender, race, and age (< 65, 65 to 74, and > or = 75 years). Actual height was correlated with estimated height using published equations. Analysis of variance revealed the effect of gender, race, or age on outcome variables.

RESULTS

White women, black women, and white men made up 54%, 23%, and 23% of the sample, respectively. Most gender differences were expected. Black women had greater weight, body mass index, arm muscle circumference, and ratio of lean to height but lower percent lean body mass than white women. Subjects over 75 years old were shorter, lighter, and had lower ratio of lean to height. Gender and age had the greatest effect on ratio of lean to height.

CONCLUSIONS/APPLICATIONS

A lean-to-height index appears to be a useful tool for tracking the status of lean mass in the elderly. Knee height may be especially useful because it, unlike stature, does not decrease with age. Furthermore, some published equations for estimating stature from knee height need adjustment, specifically for elderly black women.
