Choline is an essential nutrient affects brain development in early life. However, evidence is lacking regarding its potential neuroprotective effects in later life from community-based cohorts. This study assessed the relationship between choline intake and cognitive functioning in a sample of older adults 60 years + from the National Health and Nutrition Examination Survey 2011-2012 and 2013-2014 waves (n = 2,796). Choline intake was assessed using two nonconsecutive 24-hour dietary recalls. Cognitive assessments included immediate and delayed word recalls, Animal Fluency, and Digit Symbol Substitution Test. The average daily dietary choline intake was 307.5 mg, and the total intake (including intake from dietary supplements) was 330.9 mg, both below the Adequate Intake level. Neither dietary OR = 0.94, 95% CI (0.75, 1.17) nor total choline intake OR = 0.87, 95% CI (0.70, 1.09) was associated with changes in cognitive test scores. Further investigation adopting longitudinal or experimental designs may shed light on the issue.

Malnutrition in older people is still an unsolved issue. Clinical nurses have a key role in malnutrition prevention. This study aims to describe the individual-level variables associated with self-efficacy in nutrition care for older adults among nurses. A cross-sectional descriptive observational study was performed involving nurses from four northern Italy hospitals. The self-efficacy scale for nursing nutrition care (SE-NNC) and Multiple linear regression (MLR) models were used, enrolling 305 nurses. The mean SE-NNC total score was 53.3 ± 19.7. Considering the three dimensions of the SE-NNC, mean scores were 45.9 ± 21.7 for boosting knowledge, 55.4 ± SD = 20.3 for assessment and evidence utilization, and 57.7 ± 21.1 for care delivery. To be a younger nurse, working in a chronic care setting, and being male were associated with a higher level of self-efficacy, both considering the SE-NNC total score and its dimensions. Working in acute care settings and being an older nurse was associated with lower nursing self-efficacy in nutrition care for older adults.

This study aimed to investigate the nutritional status, nutrient intake and associated factors among older home care clients, caregivers and care recipients (≥65 years) living at home. There were a total of 78 participants, with a mean age of 78 ± 7.4 years. Nutritional status was assessed with the Mini Nutritional Assessment (MNA), nutrient intake with a three-day food record, sarcopenia with a Simple Questionnaire to Rapidly Diagnose Sarcopenia (SARC) and depression with The Geriatric Depression Scale (GDS-15). Almost one-third (32.1%) were at risk of malnutrition and 2.6% suffered from malnutrition. Impaired nutritional status was associated with depressive symptoms (β = -0.277, p = 0.015) and risk of sarcopenia (SARC points) (β = -0.401, p = 0.001). Mean protein intake was 0.9 ± 0.3 g/adjusted body weight/day. Intakes of protein and multiple vitamins and minerals were lower than recommended. In conclusion, a third of older people living at home were at risk of malnutrition or malnourished. Multiple physical, psychological and social factors in older adults were associated with nutritional status and protein intake.

To describe the nutritional and functional changes that occurred in older patients with a femur fracture following a dietary intervention and oral nutritional support implemented at an orthogeriatric unit in Aragon, Spain. Open-label, prospective study. Patients were consecutively recruited and arranged into three groups based on their CONtrolling NUTritional (CONUT^®) score and nutritional needs. Nutritional status was assessed while in hospital, and at 45-, 100- and 180-days post-hospital discharge. One hundred and sixty-nine patients [mean age: 86 years (SD ± 5.48)] were recruited (July 2017 to January 2020). At admission, 53.3% were at risk of malnutrition; 26.6% were malnourished; 20.1% were well-nourished. Variable proportions of malnourished patients at admission were well-nourished 45-, 100-, and 180-days post-discharge. CONUT^® and Barthel index correlations showed that as nutritional status enhanced, patients gained functionality. Dietary interventions and nutritional support may help restoring the nutritional and functional status of older patients with a femur fracture.

Excessive sodium consumption is a public health issue and congregate meal programs provide a unique opportunity to reduce sodium served to a large, at-risk population. A Sodium Reduction Initiative (SRI) was implemented in a congregate meal program that serves over 3,000 older adults. Nutrient analyses conducted at baseline and post-intervention were used to calculate average sodium reduction and the number of low sodium foods; targeted foods were categorized by strategy. Customer satisfaction surveys were collected at baseline and 3- and 6-months post-intervention. Kruskal Wallis and analysis of variance were used to compare sodium reduction differences. Chi-square analysis determined associations among strategies. The SRI impacted 55 foods, low sodium foods increased by 22%, and the average sodium per menu cycle was reduced by 21%. Replacement with a lower sodium food was the most frequently used strategy and had the largest sodium reduction. Sauces and main entrees were most frequently impacted, and thirteen ingredients accounted for 75% of all reduced-sodium foods. Over 50% of the 1,424 survey respondents consumed the reduced-sodium foods and food satisfaction remained stable from baseline to post-intervention. Congregate meals programs that target commonly used foods and key ingredients can significantly reduce sodium served to older adults.

It is unclear which energy expenditure prediction equation should guide weight loss interventions in older adults with obesity. We ascertained the validity of four equations commonly used in practice in a series of weight loss studies of adults aged ≥65 with a body mass index ≥30kg/m² using indirect calorimetry data. Diagnostic accuracy was defined as <10% discrepancy between predicted and measured resting metabolic rate (RMR). Mean was 73.4 years. RMR using the ReeVue was 1,643 kCal. With 59.0% accuracy, the WHO equation demonstrated the highest accuracy while the Harris-Benedict yielded 53.5% accuracy. The Owens equation demonstrated the least variability (21.5% overprediction, 27.8% underprediction) with 50.7% accuracy. A SECA bioimpedance analyzer noted the second lowest accuracy of 49.6%. Only 43.1% of measurements were within 10% of the gold-standard indirect calorimetry value using the Mifflin equation. All equations demonstrated <60% accuracy suggesting a great need for estimating energy needs.

This four-month study evaluated the virtual delivery of Fresh Conversations (FC). Participants were community-residing Iowans ages 60+ years. They were placed in one of four meeting groups based on location and participant preference: Zoom™, Adobe Connect^®, group-based Zoom™ meeting, and teleconference. Participants were invited to complete a post-meeting online survey. Data analyses were completed using data from the first survey completed by each participant (n = 115). Descriptive statistics assessed response frequencies for all questions. Chi-Square and Mann-Whitney U tests assessed the differences between groups. Overall, participants were "satisfied/very satisfied" (72.1%), learned something new (85.2%), and intended to make behavior change (79.1%); no differences were detected by the group for satisfaction or reported impacts. Only 24.3% reported technical difficulties; the Adobe Connect^® group reported the most difficulties (p = .004). These findings suggest virtual delivery of FC is well-received and perceived to be effective by participants.

Area Agencies on Aging (AAAs) and food banks provide nutritious food for in-need older adults. The objective of this study was to identify successes, challenges, and opportunities associated with meeting the food needs of older adults. We used semi-structured telephone interviews with AAA nutrition staff (n = 5), food bank program coordinators (n = 5) and executives (n = 6), and older adults (n = 60) in Iowa. AAAs and food banks identified providing healthy food and client satisfaction as successes and funding and staff/volunteer capacity as challenges. Before the pandemic, the relationships between these organizations were limited, but both saw opportunities for collaboration. Older adults described coordination between AAAs and food banks during the COVID-19 crisis. AAAs and food banks play an important role in meeting older adults' food needs, but their effectiveness is limited by challenges related to funding and capacity. There is a need to identify feasible and sustainable strategies for collaboration past this crisis.
