Physical exercise programs have been carried out in primary health care in Brazil and have provided good results in terms of effectiveness, their economic contribution has not been investigated yet. The aim of the study is to verify the feasibility of brief counseling physical activity intervention and to compare its economic cost and cost-effectiveness with supervised physical exercise intervention in primary care. A multi-arm parallel feasibility trial, with equal randomization [1:1:1] was conducted in Basic Health Units in Brazil. 61 participants were randomized in Brief Counseling Intervention (BCI), Supervised Physical Exercise Intervention (SPEI) and Control Group (CG). Interventions lasted one year. The BCI is more economical than the SPEI, costing around 50% less in the economic comparisons (session cost, annual cost and cost per participant annually). At leisure time, the cost to move one person to the physically active category at 12 months is estimated in R$369.00 for BCI and R$426.21 for the SPEI. The Incremental Cost-effectiveness Ratio (ICER) is R$310.32. The BCI is feasible and more economic, however, the cost effective is not that different. Thus, it is strongly recommended that the two interventions be offered at primary care in Brazil.
Objetivou-se relatar uma experiência de utilização de um dispositivo móvel para coleta de dados, além de descrever os procedimentos para sua implementação. A pesquisa foi composta por dois momentos: entrevistas de 2008 realizadas por meio de papel e caneta e em 2014-2015 por meio de dispositivos móveis. O processo de implementação dos questionários nesses dispositivos móveis seguiu três etapas: i) escolha do dispositivo móvel; ii) escolha do aplicativo; iii) desenvolvimento e programação do aplicativo. Quando comparada à coleta utilizando papel e caneta, a utilização de tablet apresentou uma economia monetária de 25,8%, sendo que, para uma coleta futura, essa economia seria de 99,2%, e uma economia de tempo superior à 56,9%. Os resultados apontam que o uso de tablet para coleta de dados em pesquisas epidemiológicas deve ser encorajado, uma vez que apresenta benefícios espaciais, econômicos e temporais quando comparado ao uso do papel e caneta.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
