ABSTRACT
Objetivo: Investigar a associação entre a autopercepção negativa de saúde e características individuais entre idosos de grupos comunitários do Sudeste do Brasil. Métodos: Trata-se de estudo transversal, realizado entre os anos 2014 a 2017, com amostra de 157 idosos participantes de 2 grupos de convivência de dispositivos sociais e/ou religiosos da cidade de Juiz de Fora, Minas Gerais, Brasil. Por meio de um questionário estruturado, baseado em questões utilizadas em inquérito populacional e de aferição de medidas antropométricas de peso, altura e circunferência da cintura (CC), avaliou-se a autopercepção de saúde (variável resposta) por meio da seguinte pergunta: o(a) senhor(a) diria que sua saúde está: ruim, razoável, boa ou muito boa? As respostas foram categorizadas em autopercepção de saúde negativa (ruim e razoável) e positiva (boa e muito boa). Realizaram-se estatísticas descritivas, testes Mann-Whitney, Fisher e qui-quadrado e regressão logística multivariada. Resultados: A proporção de autopercepção negativa de saúde foi de 32,5%. A autopercepção negativa de saúde associou-se à menor renda (OR=5,02; IC95%: 2,08 - 12,08), à inatividade física (OR=3,51; IC95%: 1,26 - 9,78) e à presença de duas ou mais doenças (OR=4,96; IC95%: 2,10 - 11,72), independentemente da idade e do sexo. Conclusão: A autopercepção negativa de saúde associou-se à menor renda familiar, à inatividade física e à presença de duas ou mais doenças associadas.
Objective: To investigate the association between negative self-perception of health and individual characteristics in older adults from community groups in Southeastern Brazil. Methods: This cross-sectional study was carried out between 2014 and 2017 with a sample of 157 older adults from 2 social groups held by social and/or religious services in the city of Juiz de Fora, Minas Gerais, Brazil. A structured questionnaire containing questions used in population-based surveys was used and anthropometric measurements of weight, height and waist circumference (WC) were taken. Self-rated health (the outcome variable) was assessed using the following question: would you say your health is bad, fair, good, or very good? The answers were categorized into negative self-perception (poor and fair) and positive self-perception (good and very good). Descriptive statistics, Mann-Whitney test, Fisher's test, Chi-squared test, and multivariate logistic regression were used. Results: The rate of negative self-perception of health was 32.5%. Negative self-perception of health was associated with lower levels of income (OR=5.02; 95%CI: 2.08 - 12.08), physical inactivity (OR=3.51; 95%CI: 1.26 - 9.78), and presence of two or more diseases (OR=4.96, 95%CI: 2.10 - 11.72), regardless of age and sex. Conclusion: Negative self-perception of health was associated with lower levels of income, physical inactivity and presence of two or more associated diseases.
Objetivo: Investigar la asociación entre la auto percepción negativa de salud y las características individuales entre mayores de grupos comunitarios del Sudeste de Brasil. Métodos: Se trata de un estudio transversal realizado entre los años 2014 y 2017 con la muestra de 157 mayores participantes de 2 grupos de convivencia de dispositivos sociales y/o religiosos de la ciudad de Juiz de Fora, Minas Gerais, Brasil. A través de un cuestionario estructurado basado en las preguntas utilizadas en encuesta poblacional y tras la verificación de las medidas antropométricas de peso, altura y circunferencia de la cintura (CC), se evaluó la auto percepción de la salud (variable respuesta) a través de la siguiente pregunta: ¿En su opinión su salud está mala, mediana, buena o muy buena? Las respuestas han sido categorizadas en auto percepción de salud negativa (mala y mediana) y positiva (buena y muy buena). Se realizaron las estadísticas descriptivas, las pruebas de Mann-Whitney, Fisher y chi-cuadrado y la regresión logística multivariada. Resultados: La proporción de la auto percepción negativa de salud ha sido del 32,5%. La auto percepción negativa de salud se asoció con la menor renta (OR=5,02; IC95%: 2,08 - 12,08), la inactividad física (OR=3,51; IC95%: 1,26 - 9,78) y la presencia de dos o más enfermedades (OR=4,96; IC95%: 2,10 - 11,72), independientemente de la edad y del sexo. Conclusión: La auto percepción negativa de salud se asoció con la menor renta familiar, la inactividad física y la presencia de dos o más enfermedades asociadas.

Andiroba (Carapa guianensis) seeds are the source of an oil with a wide range of biological activities and ethnopharmacological uses. However, few studies have devoted attention to innovative formulations, including nanoemulsions. The present study aimed to obtain a colloidal system with the andiroba oil using a low-energy and organic-solvent-free method. Moreover, the preliminary residual larvicidal activity of the nanoemulsion against Aedes aegypti was evaluated. Oleic and palmitic acids were the major fatty acids, in addition to the phytosterol ß-sitosterol and limonoids (tetranortriterpenoids). The required hydrophile-lipophile was around 11.0 and the optimal nanoemulsion was obtained using polysorbate 85. The particle size distribution suggested the presence of small droplets (mean diameter around 150 nm) and low polydispersity index (around 0.150). The effect of temperature on particle size distribution revealed that no major droplet size increase occurred. The preliminary residual larvicidal assay suggested that the mortality increased as a function of time. The present study allowed achievement of a potential bioactive oil in water nanoemulsion that may be a promising controlled release system. Moreover, the ecofriendly approach involved in the preparation associated with the great bioactive potential of C. guianensis makes this nanoemulsion very promising for valorization of this Amazon raw material.
