Association between phase angle of bioelectrical impedance analysis and nutritional parameters in older adults

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. Kolmogorov­Smirnov 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 80­89 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: 1.04­1.50), and hypoalbuminemia (PR: 1.50; 95%CI: 1.11­2.03). 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.

Perfil obstétrico e neonatal dos partos naturais domiciliares assistidos por enfermeiros obstetras

Objetivo: Descrever o perfil obstétrico e neonatal dos partos naturais assistidos por enfermeiros obstetras nos domicílios. Material y Método: Estudo documental de abordagem quantitativo-descritivo e retrospectivo, desenvolvido nos prontuários arquivados pelas duas únicas equipes de enfermagem obstétrica privada de Maceió, Alagoas. A coleta dos dados ocorreu entre abril a maio de 2017 e baseado na media estimada de 140; abordaram-se 72 prontuários disponíveis que cumpriram com todos os requisitos éticos de pesquisa deste cunho em relação à dispensa do termo de consentimento livre e esclarecido. Resultados: Com predomínio da faixa etária das genetrizes de 20 a 29 anos (58,3%), casadas (58,7%) e com nível superior (83,4%). Multípara (87,5%), com partos na água (62,5%), de quatro apoios (40,3%), sem laceração perineal (77,8%) e com delivramento espontâneo (94,4%). O aspecto do liquido amniótico claro (95,8%), com Apgar e o teste do coraçãozinho satisfatório para manutenção da vida (100%). Conclusão: Apesar das equipes de enfermagem obstétrica atuarem nos cenários hospitalar e domiciliar, o público procurou por partos domiciliares e evidenciou-se que parir em casa é tão seguro do que parir institucionalmente e sobretudo se respeita a opinião feminina.

Objective: To describe the obstetric and neonatal profile of natural births assisted by obstetric nurses at home. Materials and Methods: Documentary study of quantitative-descriptive and retrospective approach, carried out using the medical records filed by the only two private obstetric nursing teams of Maceió, state of Alagoas, Brazil. Data collection took place between April and May 2017 and, based on an estimated average of 140, 72 available medical records that met all ethical research requirements in relation to the waiver of the informed consent form were used. Results: 72 records were analyzed, with a predominance of the age group of 20- to 29-year-olds (58.3%), married (58.7%) and having higher education level (83.4%). Multicenter (87.5%), water births (62.5%), on four legs (40.3%), no perineal laceration (77.8%) and spontaneous placenta delivery (94.4%). Clear amniotic fluid (95.8%), APGAR and satisfactory heart test for life maintenance (100%). Conclusion: Although obstetrical nursing teams work in the hospital and home settings, people preferred home births and it was shown that giving birth at home is as safe as giving birth institutionally, especially if it takes into account women's opinion.

Objetivo: Describir el perfil obstétrico y neonatal de los partos naturales asistidos por enfermeros obstetras en los domicilios. Material y Método: Estudio documental de enfoque cuantitativo-descriptivo y retrospectivo, desarrollado con los registros archivados por los dos únicos equipos de enfermería obstétrica privada de la ciudad de Maceió, estado de Alagoas, Brasil. La recolección de datos fue entre abril y mayo de 2017 y se basó en una media estimada de 140. Finalmente se obtuvieron 72 fichas que cumplieron con todos los requisitos éticos de investigación respecto del consentimiento libre e informado. Resultados: Predominó el grupo de edad de las progenitoras de 20 a 29 años (58,3%), casadas (58,7%) y con nivel escolar superior (83,4%). Multípara (87,5%), con partos en el agua (62,5%), de cuatro apoyos (40,3%), sin laceración perineal (77,8%) y con expulsión espontánea de la placenta (94,4%). El aspecto del líquido amniótico claro (95,8%), con APGAR y el test del corazón satisfactorio para el mantenimiento de la vida (100%). Conclusión: A pesar de que los equipos de enfermería obstétrica actúan en los escenarios hospitalarios y domiciliarios, el público optó por partos domiciliarios y se evidenció que dar a luz en casa es tan seguro como dar a luz institucionalmente, sobre todo si se respeta la opinión femenina.
