The present study investigates the prediction of increased blood pressure by body mass index (BMI), waist (WC) and hip circumference (HC), and waist hip ratio (WHR) using a machine learning technique named classification tree. Data were collected from 400 college students (56.3% women) from 16 to 63 years old. Fifteen trees were calculated in the training group for each sex, using different numbers and combinations of predictors. The result shows that for women BMI, WC, and WHR are the combination that produces the best prediction, since it has the lowest deviance (87.42), misclassification (.19), and the higher pseudo R 2 (.43). This model presented a sensitivity of 80.86% and specificity of 81.22% in the training set and, respectively, 45.65% and 65.15% in the test sample. For men BMI, WC, HC, and WHC showed the best prediction with the lowest deviance (57.25), misclassification (.16), and the higher pseudo R 2 (.46). This model had a sensitivity of 72% and specificity of 86.25% in the training set and, respectively, 58.38% and 69.70% in the test set. Finally, the result from the classification tree analysis was compared with traditional logistic regression, indicating that the former outperformed the latter in terms of predictive power.

RESUMO RESUMO RESUMO RESUMO RESUMO Este estudo teve por objetivo analisar a influência da dor quanto à duração, localização e intensidade na capacidade funcional de idosos institucionalizados. Trata-se de um estudo tansversal a partir de uma amostra de 60 idosos. O instrumento foi composto por variáveis sociodemográficas, de saúde, escala numérica de dor e Índice de Barthel. Com a aplicação do Teste Qui-quadrado verificou-se diferença estatística significante entre presença de dor e as atividades: banho (p=0,015) vestir-se (p=0,041), transferência para higiene intima (p=0,001), transferência cama e cadeira (p=0,032), deambulação (p=0,010) e subir escadas (p=0,008) e a pontuação do Índice de Barthel e presença de dor, p<0,000. Diante dos resultados deste estudo constatou-se que a dor interfere de maneira negativa na capacidade funcional dos idosos.

ABSTRACT ABSTRACT ABSTRACT ABSTRACT ABSTRACT The aim of this study was to analyze the influence of pain, in terms of its duration, location and intensity, on the functional capacity of institutionalized elderly. That was a cross-sectional study carried out with a sample of 60 elderly patients. The instrument was composed by sociodemographic and health variables, the numerical pain scale and the Barthel scale. The Chi-square test showed a significant statistical difference between the presence of pain and the following activities: bathing (p=0.015) dressing (p=0.041), toilet use (p=0.001), bed-chair transfer (p=0.032), ambulation (p=0.010) and stairs climbing (p=0.008) and between total Barthel score and the presence of pain, p<0,000. The results of this study show that pain has a negative effect on the functional capacity of the elderly.

RESUMEN RESUMEN RESUMEN RESUMEN RESUMEN Este estudio tuvo como objetivo analizar la influencia del dolor cuanto a su duración, localización e intensidad en la capacidad funcional de ancianos internados en instituciones. Se trata de un estudio descriptivo con delineación transversal y una muestra de 60 ancianos. El instrumento se basa en variables sociodemográficas, de salud, escala numérica de dolor e Índice de Barthel. Con la aplicación del Test Chi-cuadrado se verificó que hay diferencia estadística significativa entre la presencia de dolor en las actividades: baño (p=0,015) vestirse (p=0,041), traslado para labores de higiene intima (p=0,001), traspaso a cama y silla (p=0,032), locomoción (p=0,010) y subir escaleras (p=0,008) y entre la puntuación total de Barthel y presencia de dolor, p<0,000. A la vista de los resultados de este estudio se constata que el dolor interfiere de manera negativa en la capacidad funcional de los ancianos.

Objective: To assess the functional capacity and to determine the difference between the means of functional capacity (basic and instrumental activities of daily living) and the age groups of elderly residents in an outlying area in the hinterland of Bahia/Northeast of Brazil. Method: Analytical study with cross-sectional design and a sample of 150 elderly individuals enrolled in four Health Units in the municipality of Jequié, Bahia, Brazil. The instrument consisted of sociodemographic and health data, the Barthel Index and the Lawton scale. Results: In all, 78.00% of the elderly were classified as dependent in the basic activities and 65.33% in the instrumental activities of daily living. Using the KruskalWallis test, we found a statistically significant difference between the means of instrumental activities and the age groups (p=0.011). Conclusion: An elevated number of elderly were classified as dependent in terms of functional capacity and increased age is related to greater impairment in the execution of instrumental activities of daily living.

Objective: To know the health-related consequences of caring for dependent relatives in older adult caregivers. Method: Qualitative research carried out with older adult women who cared for family members enrolled in a federal public home care program. The identification of the older adult caregivers was done by consulting the patient's charts, and the interview took place from March to June 2017. The data were systematized based on Content Analysis. Results: Six older adult caregivers of people with impaired functional capacity participated in the study. Three categories emerged: care-related musculoskeletal pain; health problems related to the somatization of the lived feeling; and self-care deficit by virtue of caring for another. Conclusion: The study revealed the consequences of caring for dependent family members on the health of older adult caregivers. Careful management is essential to prevent and/or reduce health problems, especially regarding the musculoskeletal system.
