RESUMEN
ABSTRACT Objective To determine whether low muscle strength and low gait speed increase the risk of disability related to basic activities of daily living in community-dwelling older adults. Methods A longitudinal study (9 years of follow-up) was conducted with 390 older adults who were independent in basic activities of daily living at baseline and answered the Katz Index at follow-up. Associations were determined using Pearson's χ2 test with a 5% significance level and logistic regression analysis. Results Increases in prevalence between baseline and follow-up were observed for low muscle strength (17.5%-38.2%), slow gait speed (26.0%-81.1%), and functional dependence (10.8%-26.6%). At follow-up, 11.7% of the participants had concomitant functional dependence, slow gait speed, and low muscle strength. Slow gait speed remained a predictor of dependence in basic activities of daily living (odds ratio=1.90; 95% confidence interval=1.06-3.41). Conclusion Slow gait speed is a predictor of functional dependence, constituting an important variable for screening functional decline.
RESUMEN
Resumo O objetivo deste estudo foi investigar prevalências de falhas no diagnóstico, no uso de anti-hipertensivos e na eficácia do tratamento medicamentoso da hipertensão, e a associação destes parâmetros com variáveis sociodemográficas, de saúde e acesso ao serviço de saúde em idosos não institucionalizados. O estudo foi descritivo, transversal, com 3478 idosos, analisados separadamente em regiões Norte/Nordeste e Sul/Sudeste. Utilizou-se a regressão múltipla de Poisson para estimar razões de prevalência brutas e ajustadas pelo tipo de serviço de saúde utilizado. Do total, 29,6% dos idosos apresentaram falhas no diagnóstico, 4,6% no uso de anti-hipertensivos e 65,3% na eficácia medicamentosa. A falha no diagnóstico associou-se ao sexo masculino, menos morbidades, ter um companheiro, raça/cor branca, ter acesso ao convênio ou serviço privado de saúde, possuir renda pessoal inferior/média e ainda trabalhar. A falha no uso de anti-hipertensivos esteve associada à renda pessoal inferior/média e trabalhar. As falhas no manejo da hipertensão são prevalentes em idosos não institucionalizados. Há necessidade de ações que minimizem os impactos negativos destas insuficiências em saúde, em um país com diferenças sociais, econômicas e étnicas.
Abstract This study aimed to investigate the prevalence of failure in hypertension diagnosis, antihypertensive drug use and drug therapy efficacy and the association of these parameters with sociodemographic, health-related and access to health services variables in community-dwelling elderly. This is a descriptive cross-sectional study with 3,478 elderly from different Brazilian regions. We used Pearson's chi-square test to verify associations between outcomes and independent variables, and Poisson multiple regression to estimate crude and adjusted prevalence ratios. Of the total, 29.6% of the elderly evidenced failure in the diagnosis, 4.6% in the use of antihypertensives and 65.3% in drug efficacy. Diagnostic failure was associated with males, presence of morbidity, having a partner, white skin color/ethnicity, having access to the health covenant or private health service, with low/medium personal income and working. Antihypertensive use failure was associated with low/medium personal income and work. Hypertension management failures are prevalent in community-dwelling elderly. There is a need for actions that minimize the negative impact of these health shortcomings, in a country burdened by social, economic and ethnic differences.
