LB014-SUN SERUM BIOMARKERS THAT PREDICT LEAN BODY MASS (LBM) LOSS OVER BEDREST (BR) IN OLDER ADULTS

DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n5p530 Anthropometric indicators enable professionals for predicting risk of falls in the elderly; however, there is a gap in literature on reference values. This study analyzes anthropometric indicators such as screening tests for falls in the elderly. Cross-sectional population-based systematic sampling was conducted through a household survey and body composition assessment. Anthropometric measurements were performed using portable electronic scale and stadiometer. Bioimpedance device was used to measure body mass index, body fat and lean body mass. Falls were evaluated in the 12 months preceding the interview as a dependent variable. Discriminatory analysis was performed for falls through the ROC curve, sensitivity, specificity, positive and negative predictive values. Overall, 275 older adults participated in this study, whose prevalence of falls was 23.6%. The average body mass index was 27.8kg/cm2 and 52.1% of individuals were overweight. Among older men, height (ROC=0.68; 95%CI 0.54-0.78) and lean body mass (ROC=0.63, 95%CI 0.58- 0.76) were associated to the occurrence of falls. When considering cutoff of 52.2kg and 166cm, sensitivity was obtained in 75% and high negative predictive values (88.1% and 89.1% respectively). For women, lean body mass (ROC=0.61, 95%CI 0.30-0.49) and body mass (ROC=0.60, 95%CI 0.53-0.72) were relevant from the optimal cutoff point of 28.9% and 57.2kg/m2. Lean body mass was more sensitive (63.2%) and body mass little more specific (64.3%), both with high negative predictive values (82.0% and 83.0%). The indicators used were able to discriminate older adults who have suffered from falls.

Frail Older Adults

Purpose Frailty is a geriatric syndrome which can be reversible or less severe through appropriate nutritional interventions. In the present study, to test the efficiency of individualized nutritional intervention was conducted a comprehensive assessment of the nutritional status of frail older adults and evaluation of the effect of nutritional intervention on the nutritional status of pre-frail older patients. Design/methodology/approach Frail older adults (n = 43; mean age 84.6 ± 6.4 years old; 81.4% women) had nutritional status assessed using nutritional anthropometry, body composition, and food frequency questionnaire. Pre-frail patients (n = 16; mean age 68.4 ± 5.5 years old; 81.3% women) for eight weeks were consuming 1.0 g protein/kg BW/day. Robust older adults formed a control group (n = 29; mean age 69.3 ± 5.3 years old; 82.8% women). Findings Frail older adults had weight and muscle mass loss, and their diet variety was sufficient. After the intervention, pre-frail patients increased their protein consumption by 25.8% (P = 0.002). An increase in lean body mass (+1.0 kg), skeletal muscle mass (+0.3 kg) and improvement in physical performance was also observed. Originality/value An individual diet for pre-frail older adults can reverse weight loss and increase lean body mass, furthermore preventing or delaying the development of frailty syndrome. Moreover, increased protein consumption improves physical performance of pre-frail older adults.

Community Dwelling Older Adults

Abstract Objective: This study investigated the impact of recipe and single-use herb/spice packet provision on egg intake and protein intake in community-dwelling individuals aged over 55 years. Design: Using a randomised-controlled intervention design, 100 older adults were randomised to receive (n 53) or not receive (n 47) high-protein egg-based recipes and herb/spice packets through the post for 12 weeks, from June to December 2016. Egg intake, protein intake, adverse events, lean body mass and functional measures of lean body mass were measured at baseline, after the 12 weeks and after a further 12 weeks. Setting: Bournemouth, UK. Participants: Community-dwelling older adults. Results: Intention-to-treat data were analysed using regression, controlling for various demographic and lifestyle characteristics. Ninety-three individuals (intervention, n 50; control, n 43) completed assessments at all three time points. Egg intakes increased by end of intervention in both groups (mean: 4–5 eggs/month). After a further 12 weeks, higher egg intakes were sustained in the intervention group, while egg intakes in the control group returned to baseline levels (between-group difference: β = −0·124, P = 0·047). No differences were found in other measures (largest β = −0·106, P = 0·12). Conclusions: The provision of high-protein egg-based recipes and single-use herb/spice packets over 12 weeks increased egg intakes up to 12 weeks after end of intervention. Other factors may explain increased egg intakes during the intervention, but the sustained effects most plausibly result directly from recipe provision. Limited effects in other measures suggest that the recipes may have replaced as opposed to added to existing protein intakes.
