Introduction: Phase angle (PhA) is a Bioelectrical impedance analysis (BIA) parameter representing an indicator of cellular health and has been suggested as a biomarker of nutritional status. Objective: To evaluate the association between PhA and nutritional parameters in older adults. Methods: A cross-sectional study was conducted with community-dwelling older adults. Body mass index (BMI), arm muscle circumference (AMC), calf circumference (CC), body fat percentage (BF%), appendicular skeletal muscle mass (ASMM), serum albumin, mini-nutritional assessment (MNA), and PhA were assessed. Kolmogorov–Smirnov test, Spearman's correlation coefficient, chi-square test, and Poisson regression models were performed. Results: 144 participants were included in the study, and most of them were female, aged ≥80 years, and underweight. Most older adults with lower PhA were women, aged range 80–89 years, and with reduced ASMM (p<0.05). PhA presented a significant correlation with age (r=–0.417; p<0.001), ASMM (r=0.427; p<0.001), AMC (r=0.195; p=0.019) and BF% (r=–0.223; p=0.007). Older adults with lower PhA present reduced ASMM (PR: 1.25; 95%CI: 1.04–1.50), and hypoalbuminemia (PR: 1.50; 95%CI: 1.11–2.03). Conclusion: PhA is related to commonly nutritional indicators used in clinical practice and could be an important biomarker of muscle mass reserves in community-living older adults of both sexes.

Introduction: Currently, there is a greater concern of individuals with vision and imposition of perfect body. The change in the perception of the body image is motivated by social, environmental and, strongly, by the media, which imposes a beauty pattern associated with thinness or muscular bodies. A distorted view of the actual body image has repercussions on the levels of well-being and self-esteem, as well as in the decision-making related to nutrition and health in general. The objective of this study is to verify the anthropometric nutritional status and perception of the body image of users of primary care. Methods: A cross-sectional study conducted with users of primary care in the city of Fátima-Bahia. Socio-demographic information, anthropometric evaluation (weight, height and waist circumference) and perception of ideal and real body image were collected. Results: 89 users participating in the HiperDia program participated in the study, the most were women (87.6%) and adults (67.4%). Regarding nutritional status, 61.8% were overweight and 79.8% had abdominal fat accumulation. Most of the individuals showed dissatisfaction due to overweight (78.7%) and 6.7% of dissatisfaction for thinness. Of the individuals with adequate nutritional status, 73.5% also had some type of body dissatisfaction (both for thinness or excess). Conclusion: The majority of subjects presented with overweight and body image dissatisfaction. It is essential to evaluate the body image of the individuals on the part of the health professionals, assisting the clinical practice and guaranteeing an integral attention to the individual.
