RESUMO

BACKGROUND: Data on the prevalence of sarcopenia among older adults in Ireland are lacking. AIMS: To assess the prevalence and determinants of sarcopenia among community-dwelling older adults in Ireland. METHODS: This cross-sectional analysis involved n = 308 community-dwelling adults aged ≥ 65 y living in Ireland. Participants were recruited via recreational clubs and primary healthcare services. Sarcopenia was defined according to the 2019 European Working Group on Sarcopenia in Older People (EWGSOP2) criteria. Skeletal muscle mass was estimated using bioelectrical impedance analysis, strength was measured via handgrip dynamometry, and physical performance was assessed using the Short Physical Performance Battery. Detailed information was collected on demographics, health, and lifestyle. Dietary macronutrient intake was measured via a single 24 h recall. Binary logistic regression was used to examine potential demographic, health, lifestyle, and dietary determinants of sarcopenia (where both probable and confirmed sarcopenia were combined). RESULTS: The prevalence of EWGSOP2-defined probable sarcopenia was 20.8% and confirmed sarcopenia was 8.1% (5.8% had severe sarcopenia). Polypharmacy (OR 2.60, 95% confidence interval [CI] 1.3, 5.23), height (OR 0.95, 95% CI 0.91, 0.98), and Instrumental Activities Of Daily Living (IADL) score (OR 0.71, 95% CI 0.59, 0.86) were independently associated with sarcopenia (probable and confirmed combined). There were no independent associations between energy-adjusted macronutrient intakes, as determined by 24 h recall, and sarcopenia. CONCLUSION: Sarcopenia prevalence within this sample of community-dwelling older adults in Ireland is broadly similar to other European cohorts. Polypharmacy, lower height, and lower IADL score were independently associated with EWGSOP2-defined sarcopenia.

RESUMO

BACKGROUND: Malnutrition negatively impacts on health, quality of life and disease outcomes in older adults. The reported factors associated with, and determinants of malnutrition, are inconsistent between studies. These factors may vary according to differences in rate of ageing. This review critically examines the evidence for the most frequently reported sociodemographic factors and determinants of malnutrition and identifies differences according to rates of ageing. METHODS: A systematic search of the PubMed Central and Embase databases was conducted in April 2019 to identify papers on ageing and poor nutritional status. Numerous factors were identified, including factors from demographic, food intake, lifestyle, social, physical functioning, psychological and disease-related domains. Where possible, community-dwelling populations assessed within the included studies (N = 68) were categorised according to their ageing rate: 'successful', 'usual' or 'accelerated'. RESULTS: Low education level and unmarried status appear to be more frequently associated with malnutrition within the successful ageing category. Indicators of declining mobility and function are associated with malnutrition and increase in severity across the ageing categories. Falls and hospitalisation are associated with malnutrition irrespective of rate of ageing. Factors associated with malnutrition from the food intake, social and disease-related domains increase in severity in the accelerated ageing category. Having a cognitive impairment appears to be a determinant of malnutrition in successfully ageing populations whilst dementia is reported to be associated with malnutrition within usual and accelerated ageing populations. CONCLUSIONS: This review summarises the factors associated with malnutrition and malnutrition risk reported in community-dwelling older adults focusing on differences identified according to rate of ageing. As the rate of ageing speeds up, an increasing number of factors are reported within the food intake, social and disease-related domains; these factors increase in severity in the accelerated ageing category. Knowledge of the specific factors and determinants associated with malnutrition according to older adults' ageing rate could contribute to the identification and prevention of malnutrition. As most studies included in this review were cross-sectional, longitudinal studies and meta-analyses comprehensively assessing potential contributory factors are required to establish the true determinants of malnutrition.

RESUMO

BACKGROUND: Malnutrition affects approximately 20% of older adult populations in Europe, yet their views on the condition are rarely explored. This qualitative study aimed to explore the experiences of older adults living with malnutrition and prescribed oral nutritional supplements in the community setting. METHODS: Semi-structured individual interviews were used to collect data from 13 community-dwelling individuals aged ≥60 years with a current or previous prescription for oral nutritional supplements. Self-perceived health status was measured using the EuroQol EQ-5D-5L, a short questionnaire and visual analogue scale. Interviews were audio-recorded and transcribed verbatim. Interview data were organized using NVivo 12 and analyzed using inductive thematic analysis. RESULTS: Median age was 80.0 (interquartile range 19.5) years, seven were male and six were female. Median health score was 60.0 (interquartile range 35.0) out of 100. Almost one-third reported severe or extreme problems with usual activities, and pain or discomfort. One main theme was identified from the interviews: 'It takes a village', with four subthemes (i) 'I get by with a little help from my friends', (ii) 'The obvious diagnosis', (iii) 'The missing T in MDT' and (iv) 'Confusion'. Participants with malnutrition reported relying on friends, family and carers with poor multidisciplinary team communication and lack of dietetic support. CONCLUSIONS: Participants in this study experienced poor management of malnutrition with missing links between the hospital and community healthcare settings, and lack of dietetic services. Patient views should be used to inform public health guidelines and guide future interventions in the community to improve the health status of older adults with malnutrition.

RESUMO

BACKGROUND: Approximately 17% of the European Union workforce is engaged in shift work. Shift work has been associated with a number of chronic conditions, including obesity and obesity-related metabolic diseases. The aim of this study was to explore the dietary and lifestyle behaviours of shift workers with a healthy vs. overweight/obese body mass index (BMI). METHODS: A cross-sectional study was conducted on 1080 shift workers using a 15-min, telephone-administered questionnaire developed from qualitative research on Irish shift workers and national dietary intake data. Demographic and work-related factors, as well as dietary and lifestyle behaviours were recorded. BMI was calculated using self-reported height and weight. Univariate and multivariate logistic regression methods were used to analyze data according to BMI category. RESULTS: Over 40% of shift workers were classified as overweight or obese. Multivariate analysis indicated that being male [P < 0.001, aOR = 2.102, 95% CI (1.62-2.73)] and middle- or older-aged were independently associated with overweight and obesity [P < 0.001, aOR = 2.44 95% CI (1.84-3.24) and P < 0.001, aOR = 2.9 95% CI (1.94-4.35), respectively]. Having a medium-high consumption of fried foods was independently associated with overweight and obesity [aOR = 1.38, 95% CI (1.06-1.8)]. CONCLUSIONS: Similar to the general population, overweight and obesity were strongly associated with male sex and middle- or older-age. Male shift workers may benefit from targeted dietary and lifestyle advice specifically focused on limiting fried foods to help protect against overweight and obesity.

RESUMO

BACKGROUND: Health-promoting programmes must demonstrate sustained efficacy in order to make a true impact on public health. This study aimed to determine the effect of the Healthy Incentive for Pre-schools project on health-promoting practices in full-day-care pre-schools 18 months after a training intervention. METHODS: Thirty-seven pre-schools completed the initial study and were included in this follow-up study. The intervention consisted of one training session with either the pre-school 'manager-only' or 'manager and staff' using a specifically developed needs-based training resource pack comprised of written educational material and a validated health-promoting practice evaluation tool. Direct observation data of health-promoting practices were collected and allocated a score using the evaluation tool by a research dietitian at three time points; pre-intervention, between 6 and 9 months post-intervention and at 18-month follow-up. An award system was used to incentivise pre-schools to improve their scores. RESULTS: Health-promoting practice scores improved significantly (P < 0.001) from the 6-9 month post-intervention to the 18-month follow-up evaluation. No significant differences were observed between 'manager-only' and 'manager and staff' trained pre-schools. CONCLUSIONS: The introduction of a pre-school evaluation tool supported by a training resource was successfully used to incentivise pre-schools to sustain and improve health-promoting practices 18 months after intervention training.

RESUMO

Background: Approximately 17% of the European workforce is engaged in shift work. How the experience of shift work impacts on the dietary and lifestyle practices of workers is unclear. Methods: Overall, 15 focus groups were conducted by two researchers, with 109 participants. The initial focus group was carried out with both researchers present, to ensure consistency in facilitation. Both researchers thematically analysed all data collected. Results: Shift work was described as affecting many areas of workers' lives. Three overarching themes were identified: (i) impact on eating behaviour; (ii) impact on other lifestyle behaviours including physical activity, sleep, alcohol consumption, smoking; and (iii) impact on psychosocial health and wellbeing. There appeared to be overlap between the effect of shift work and the effect of individual internal factors in influencing workers' decision-making with regard to lifestyle practices. Conclusions: Shift work affects many areas of workers' lives, negatively impacting on eating and lifestyle behaviours and psychosocial health. This study augments the current literature as it highlights the role internal motivation plays in workers' lifestyle choices. The research should help inform the development of public health strategies to minimize the impact of shift work, such as specialist behavioural change interventions specific to this group.

RESUMO

Traditionally only a small proportion of the workforce was engaged in shift work. Changing economic pressures have resulted in increased engagement in shift work, with approximately 17 % of the workforce in Europe engaged in this work pattern. The present narrative review aimed to summarise the data on the effects of shift work on the diet, lifestyle and health of employees, while addressing the barriers to, and opportunities for, improving health among shift workers. Shift work can result in low-quality diet and irregular eating patterns. Adverse health behaviours are also reported; particularly increased smoking and poor sleep patterns. These altered lifestyle habits, in conjunction with disruption to circadian rhythms, can create an unfavourable metabolic phenotype which facilitates the development and progression of chronic disease. Although the data are inconclusive due to issues such as poor study design and inadequate control for confounding factors; shift workers appear to be at increased mental and physical health risk, particularly with regard to non-communicable diseases. Information is lacking on the obstacles to leading a healthier lifestyle while working shifts, and where opportunities lie for intervention and health promotion among this group. In order to provide an informed evidence base to assist shift workers in overcoming associated occupational hazards, this gap must be addressed. This review highlights the unique nutritional issues faced by shift workers, and the subsequent effect on health. In societies already burdened with increased incidence of non-communicable chronic diseases, there is a clear need for education and behaviour change interventions among this group.

RESUMO

BACKGROUND: Resting metabolic rate (RMR) prediction equations are often used to calculate RMR in athletes; however, their accuracy and precision can vary greatly. OBJECTIVE: The aim of this systematic review and meta-analysis was to determine which RMR prediction equations are (i) most accurate (average predicted values closest to measured values) and (ii) most precise (number of individuals within 10% of measured value). DATA SOURCES: A systematic search of PubMed, CINAHL, SPORTDiscus, Embase, and Web of Science up to November 2021 was conducted. ELIGIBILITY CRITERIA: Randomised controlled trials, cross-sectional observational studies, case studies or any other study wherein RMR, measured by indirect calorimetry, was compared with RMR predicted via prediction equations in adult athletes were included. ANALYSIS: A narrative synthesis and random-effects meta-analysis (where possible) was conducted. To explore heterogeneity and factors influencing accuracy, subgroup analysis was conducted based on sex, body composition measurement method, athlete characteristics (athlete status, energy availability, body weight), and RMR measurement characteristics (adherence to best practice guidelines, test preparation and prior physical activity). RESULTS: Twenty-nine studies (mixed sports/disciplines n = 8, endurance n = 5, recreational exercisers n = 5, rugby n = 3, other n = 8), with a total of 1430 participants (822 F, 608 M) and 100 different RMR prediction equations were included. Eleven equations satisfied criteria for meta-analysis for accuracy. Effect sizes for accuracy ranged from 0.04 to - 1.49. Predicted RMR values did not differ significantly from measured values for five equations (Cunningham (1980), Harris-Benedict (1918), Cunningham (1991), De Lorenzo, Ten-Haaf), whereas all others significantly underestimated or overestimated RMR (p < 0.05) (Mifflin-St. Jeor, Owen, FAO/WHO/UNU, Nelson, Koehler). Of the five equations, large heterogeneity was observed for all (p < 0.05, I2 range: 80-93%) except the Ten-Haaf (p = 0.48, I2 = 0%). Significant differences between subgroups were observed for some but not all equations for sex, athlete status, fasting status prior to RMR testing, and RMR measurement methodology. Nine equations satisfied criteria for meta-analysis for precision. Of the nine equations, the Ten-Haaf was found to be the most precise, predicting 80.2% of participants to be within ± 10% of measured values with all others ranging from 40.7 to 63.7%. CONCLUSION: Many RMR prediction equations have been used in athletes, which can differ widely in accuracy and precision. While no single equation is guaranteed to be superior, the Ten-Haaf (age, weight, height) equation appears to be the most accurate and precise in most situations. Some equations are documented as consistently underperforming and should be avoided. Choosing a prediction equation based on a population of similar characteristics (physical characteristics, sex, sport, athlete status) is preferable. Caution is warranted when interpreting RMR ratio of measured to predicted values as a proxy of energy availability from a single measurement. PROSPERO REGISTRATION: CRD42020218212.

RESUMO

BACKGROUND: Malnutrition is underdiagnosed in primary care. GPs are key healthcare contacts for older adults at risk of protein-energy malnutrition; however, lack of knowledge and confidence in its diagnosis and treatment is often reported. AIM: To evaluate the impact of a bespoke online education module on GP malnutrition knowledge and management. DESIGN & SETTING: A prospective pre-post pilot study with 23 GPs and eight GP trainees in the Republic of Ireland. METHOD: The module included units on the following: 'malnutrition definition, prevalence, and latest evidence'; 'identifying malnutrition in clinical practice'; 'food-first advice'; 'reviewing malnutrition'; and 'oral nutritional supplements'. Participant knowledge was measured using a multiple choice questionnaire (MCQ) before and after the module (n = 31), and 6 weeks following completion (n = 11). Case studies assessing identification and management of malnutrition were evaluated by a clinical specialist dietitian with expertise in managing malnutrition. Changes in assessment performance were calculated using paired t-tests. Acceptability was evaluated using a questionnaire. RESULTS: Post-training, 97% of GPs increased MCQ scores from baseline (+25%, P<0.001), with the greatest improvement in 'identifying malnutrition in clinical practice' (mean increase 47%, P<0.001). Eleven GPs completed the 6-week MCQ with scores remaining significantly higher than baseline (mean increase 15%, P = 0.005); 'identifying malnutrition in clinical practice' remained the most highly scored (mean increase 40%, P<0.001). Seventeen GPs completed the case studies; 76% at baseline and 88% post-module correctly calculated malnutrition risk scores. Appropriate malnutrition management improved for 47% of GPs after module completion. CONCLUSION: This e-learning module improved malnutrition knowledge, with good short-term retention in a small cohort. Development of online evidence-based nutrition education may improve GP nutrition care.

RESUMO

When treating malnutrition, oral nutritional supplements (ONSs) are advised when optimising the diet is insufficient; however, ONS usage and user characteristics have not been previously analysed. A retrospective secondary analysis was performed on dispensed pharmacy claim data for 14,282 anonymised adult patients in primary care in Ireland in 2018. Patient sex, age, residential status, ONS volume (units) and ONS cost (EUR) were analysed. The categories of 'Moderate' (<75th centile), 'High' (75th-89th centile) and 'Very High' ONS users (≥90th centile) were created. The analyses among groups utilised t-tests, Mann-Whitney U tests and chi-squared tests. This cohort was 58.2% female, median age was 76 years, with 18.7% in residential care. The most frequently dispensed ONS type was very-high-energy sip feeds (45% of cohort). Younger males were dispensed more ONSs than females (<65 years: median units, 136 vs. 90; p < 0.01). Patients living independently were dispensed half the volume of those in residential care (112 vs. 240 units; p < 0.01). 'Moderate' ONS users were dispensed a yearly median of 84 ONS units (median cost, EUR 153), 'High' users were dispensed 420 units (EUR 806) and 'Very High' users 892 yearly units (EUR 2402; p < 0.01). Further analyses should focus on elucidating the reasons for high ONS usage in residential care patients and younger males.

RESUMO

Older adults (≥65 years) are the fastest growing population group. Thus, ensuring nutritional well-being of the 'over-65s' to optimise health is critically important. Older adults represent a diverse population - some are fit and healthy, others are frail and many live with chronic conditions. Up to 78% of older Irish adults living independently are overweight or obese. The present paper describes how these issues were accommodated into the development of food-based dietary guidelines for older adults living independently in Ireland. Food-based dietary guidelines previously established for the general adult population served as the basis for developing more specific recommendations appropriate for older adults. Published international reports were used to update nutrient intake goals for older adults, and available Irish data on dietary intakes and nutritional status biomarkers were explored from a population-based study (the National Adult Nutrition Survey; NANS) and two longitudinal cohorts: the Trinity-Ulster and Department of Agriculture (TUDA) and the Irish Longitudinal Study on Ageing (TILDA) studies. Nutrients of public health concern were identified for further examination. While most nutrient intake goals were similar to those for the general adult population, other aspects were identified where nutritional concerns of ageing require more specific food-based dietary guidelines. These include, a more protein-dense diet using high-quality protein foods to preserve muscle mass; weight maintenance in overweight or obese older adults with no health issues and, where weight-loss is required, that lean tissue is preserved; the promotion of fortified foods, particularly as a bioavailable source of B vitamins and the need for vitamin D supplementation.

RESUMO

Parental perceptions and use of neighborhood facilities are important factors that are related to children's dietary intake and physical activity. The aim of this study was to examine the association between neighborhood deprivation index, parents' perceptions of their neighborhood environment, and healthy/unhealthy markers of child dietary intake, physical activity, and TV screen time. This cross-sectional study was conducted in Dublin, Ireland. The lifestyle behaviors among children and parental perceptions of their neighborhood environment were reported by the parents of 276 children aged 3-5 years by using parent-completed questionnaires. Deprivation index was assessed using the geographic information system (GIS). Data were analyzed using binary logistic regression, adjusting for socio-demographic confounders. In adjusted models, high deprivation index was associated with parental perception of the neighborhood as unsafe for walking and cycling due to crime (OR 1.59, 95% CI 1.04-2.43, p = 0.031) and children's low engagement in structured physical activity (OR 0.35, 95% CI 0.17-0.72, p = 0.004). Parental perceptions of an unsafe neighborhood due to heavy traffic were negatively correlated with children's active play (OR 0.73, 95% CI 0.55-0.95, p = 0.022). Children whose parents reported high satisfaction with the number of local sit-in and takeaway restaurants were 41% more likely to consume confectionary/sugar sweetened beverages (SSBs) weekly. In this age group, parents play an important role in children's lifestyle behaviors; therefore, a better understanding of parents' perceptions and their use of neighborhood facilities could contribute to creating a healthy environment for this age group.

RESUMO

In Ireland, television (TV) screen time is a highly prevalent sedentary behavior among children aged less than five years. Little is known about the influence of parental rules and policies or screen time availability and accessibility within the home on children's TV screen time behaviors. This cross-sectional study aimed to examine the extent to which parents' sociodemographic and sedentary behaviors are associated with children's TV screen time; and to determine the associations between parents' rules and practices, home physical environment and children's daily TV viewing. Three hundred and thirty-two children aged 3-5 years and their parents participated in the study. Children's TV screen time and home environmental characteristics (parents' rules and practices and the physical environment) were assessed using questions from standardized and validated questionnaires. The data were analyzed using binary logistic regression. Within the different sedentary behaviors evaluated, parents' TV viewing was positively associated with children's TV screen time (OR 1.65, 95%CI 1.09-2.50, p = 0.018). Leaving the TV on, whether or not it was being watched, was associated with a 38% increased probability of children watching ≥ 1 h TV daily. Children whose parents restricted their outdoor activity were more likely to watch ≥ 1 h TV daily (OR 2.01, 95%CI 1.04-3.88, p = 0.036). Findings from the study demonstrated that parents' own screen time behaviors, leaving the TV on whether it was being watched or not and restricting outdoor play were associated with higher children's TV viewing in the home environment. This knowledge is essential to inform future interventions aimed to address the increase in screen time among young children.

RESUMO

Protein supplementation is an attractive strategy to prevent loss of muscle mass in older adults. However, it could be counterproductive due to adverse effects on appetite. This systematic review and meta-analysis aimed to determine the effects of protein supplementation on appetite and/or energy intake (EI) in healthy older adults. MEDLINE, The Cochrane Library, CINAHL, and Web of Science were searched up to June 2020. Acute and longitudinal studies in healthy adults ≥60 y of age that reported effects of protein supplementation (through supplements or whole foods) compared with control and/or preintervention (for longitudinal studies) on appetite ratings, appetite-related peptides, and/or EI were included. Random-effects model meta-analysis was performed on EI, with other outcomes qualitatively reviewed. Twenty-two studies (9 acute, 13 longitudinal) were included, involving 857 participants (331 males, 526 females). In acute studies (n = 8), appetite ratings were suppressed in 7 out of 24 protein arms. For acute studies reporting EI (n = 7, n = 22 protein arms), test meal EI was reduced following protein preload compared with control [mean difference (MD): -164 kJ; 95% CI: -299, -29 kJ; P  = 0.02]. However, when energy content of the supplement was accounted for, total EI was greater with protein compared with control (MD: 649 kJ; 95% CI: 438, 861 kJ; P < 0.00001). Longitudinal studies (n = 12 protein arms) showed a higher protein intake (MD: 0.29 g ⋅ kg-1 ⋅ d-1; 95% CI: 0.14, 0.45 g ⋅ kg-1 ⋅ d-1; P < 0.001) and no difference in daily EI between protein and control groups at the end of trials (MD: -54 kJ/d; 95% CI: -300, 193 kJ/d; P  = 0.67). While appetite ratings may be suppressed with acute protein supplementation, there is either a positive effect or no effect on total EI in acute and longitudinal studies, respectively. Therefore, protein supplementation may represent an effective solution to increase protein intakes in healthy older adults without compromising EI through appetite suppression. This trial was registered at PROSPERO as https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42019125771 (CRD42019125771).

RESUMO

Introduction: The syndrome of Relative Energy Deficiency in Sport (RED-S) consensus statements recognise that male athletes might have impaired fertility in terms of the Exercise Hypogonodal Male Condition (ExHMC). Thus, the aims of this study were to (1) identify risk of ExHMC in active males in various sports and (2) determine if associations between risk of ExHMC and health problems interfering with training and competition exist. Methods: A questionnaire was distributed online (November 2018-January 2019) using questions derived from the "Androgen Deficiency in the Aging Male Questionnaire" (ADAM-Q) to assess risk of ExHMC. Additional questions were included to collect information on participant demographics, injury and illness history and dietary habits. Logistic regression analyses explored differences between groups. Results: Risk of ExHMC was identified in 23.3% (n = 185) of 794 questionnaire participants. Following multivariate analyses, risk of ExHMC was independently associated with a lower than normal sex drive rating within the last month (OR 7.62, 95%CI 4.99-11.63) and less than three morning erections per week within the last month (OR: 4.67, 95%CI 3.23-6.76). Risk of ExHMC was associated with 15-21 days absence from training or competition during the previous 6 months due to overload injuries in the univariate analysis (OR = 2.69, 95% CI = 1.24-5.84). Conclusion: Risk of ExHMC and associated symptoms in this heterogeneous sample may be indicative of RED-S. Confounding factors such as over-training, medication use, fatigue and psychological stress need to be considered. Identification of male athletes exhibiting physiological symptoms associated with RED-S requires more research.

RESUMO

BACKGROUND: Low energy availability results in physiological adaptations which contribute to unfavourable health outcomes. Little information exists on perceptions of nutritional advice to eat more food to maintain health and enhance performance. The aim of this study was to explore athletes' and coaches' perceptions towards advice to athletes to eat larger than their current quantities of food and to explore how nutritionists could deliver this advice. METHODS: Semi-structured interviews (~20 min in length) were conducted using online communication technology, audio-recorded, and transcribed verbatim. The interview explored perceptions of the nutritional advice provided, its role in health and performance, and the challenges to eating larger amounts of food. Data were analysed using NVIVO 1.2 using an inductive thematic approach. RESULTS: Nine elite athletes (female = 6; males = 3) and nine high-performance coaches (female = 3; male = 6) completed the semi-structured interviews. Athletes reported improved training consistency, fewer injuries and illnesses, and improved resilience when consuming adequate energy and nutrients to meet their needs. Lack of time and meal preparation difficulties were the main challenges faced to fuelling. CONCLUSIONS: Although education about under-fuelling is important, motivating, enabling, and supporting athletes to change behaviour is pivotal to increasing athlete self-awareness and to make long-term nutritional changes.

RESUMO

BACKGROUND: Oral nutritional supplements (ONS) are recommended for patients who are malnourished or at risk of malnutrition. Appropriate ONS prescribing requires regular monitoring to assess its continued requirement. Previous research identified long-term ONS prescriptions (>6 months) without review, with 70% of these influenced by social factors. AIM: To investigate the characteristics of long-term ONS users in Ireland and the determinants of larger volumes of ONS dispensing. DESIGN & SETTING: Secondary analysis of anonymous dispensed pharmacy claims data of patients dispensed standard ONS for 12 consecutive months in 2018 (n = 912). METHOD: Factors showing significant (P<0.05) univariate associations with above the median consumption of ONS units were entered into a multivariable model. RESULTS: Median age was 76 (range 18 to 101) years, with 66.9% of the sample being ≥65 years. Almost 70% of the samples were on polypharmacy (45.6%; ≥5 medications) or excessive polypharmacy (21.5%; ≥10 medications). Younger age and being on polypharmacy for drugs having an effect on the central nervous system (CNS) were significantly associated with being dispensed more ONS units in univariate and multivariate analysis. Those patients in the age range 18 to 44 were 2.5 fold more likely to be prescribed more ONS units (odds ratio [OR] 2.5; 95% confidence interval [CI] 1.5 to 4.3; P<0.001). Patients using CNS drugs or on CNS polypharmacy were more likely to be prescribed more ONS units (ORs 1.2 and 2.4; 95% CI 0.9 to 1.4 and 1.3 to 4.4 respectively; P = 0.029). CONCLUSION: Older age and polypharmacy characterise long-term ONS users in this study. Younger age and CNS medication polypharmacy are predictors of more ONS units prescribed over a year.

RESUMO

BACKGROUND & AIMS: Understanding how older adults perceive their nutritional needs and malnutrition risk is important to inform strategies to improve prevention and management of the condition. This scoping review aimed to identify, characterize and summarize the findings from studies analysing community-dwelling older adults' opinions and perceptions towards their nutritional needs and malnutrition risk. METHODS: An electronic literature search was carried out using three databases, Pubmed, Embase, and CINAHL up to January 2020. Articles were reviewed following PRISMA guidelines. RESULTS: A total of 16,190 records were identified and reviewed with 15 studies being included, all of which were conducted in high income countries. Common conceptual categories that were identified included; older community-dwelling adults consider that a healthy diet for them is the same as that recommended for the general population, consisting of fruits, vegetables, reduced fat and reduced sugar. Weight loss was seen as a positive outcome and a normal component of the ageing process. Lack of appetite was identified by participants in the majority of studies as a barrier to food intake. CONCLUSIONS: This review shows how older community-dwelling adults, with a high risk of malnutrition, follow dietary public health recommendations for the general population and have a greater awareness of the risks of overweight. The implementation of nutritional guidelines that consider the nutritional needs of all older adults and education of non-dietetic community healthcare professionals on providing appropriate nutritional advice to this population are warranted.

RESUMO

PURPOSE: Credible evidence-based diet and nutrition advice is essential for patients with cancer. This study aimed to explore what advice patients with cancer obtained before a formal dietetic visit. METHODS: A multicenter, observational study was conducted in seven hospital-based oncology services. Consecutive patients were recruited at first dietetic assessment. In addition to routine dietetic assessment, participants completed a four-item questionnaire describing diet and nutrition advice obtained since diagnosis. RESULTS: Seventy-seven patients participated. More than 80% had multiple nutrition-impact symptoms. In total, 53 (69%) obtained advice from professional and nonprofessional sources before dietetic visit. Family and friends were the most common sources of advice. More than one third got advice from (nondietetic) healthcare professionals. Most advice related to "foods to include" (61%) and "foods to avoid" (54%) in the diet. Many of the "foods to avoid" were important sources of micro- and macronutrients. Advice about dietary supplements (31%) and specific diets (28%) was common, rarely evidence-based, and frequently contradictory. Participants found it difficult to discern what advice was trustworthy and reliable. Despite this, most followed the advice. CONCLUSION: The majority of patients received diet and nutrition advice before first dietetic visit. Most of this came from nonprofessional sources. Any advice from nondietetic healthcare professionals was inconsistent or vague. This was mainly related to the avoidance and/or inclusion of particular foods and was often contradictory. Nevertheless, patients usually followed such advice fully. To help manage their frequent nutrition-impact symptoms and resolve the contradictory advice they had received, many expressed the need for earlier professional dietetic consultation.
