Comparação de estimativas de inquéritos de base populacional

Abstract

OBJECTIVE:To compare estimates obtained through household and telephone surveys for monitoring, intervention and development of health policies. METHODS:The study analyzed data from 2,526 and 1,900 individuals aged 18 and over, living in Campinas, SP, interviewed by the household survey (ISACamp) and by the telephone survey (Vigitel), respectively. Sex, age and schooling were used to characterize the studied population. Prevalence estimates and 95% confi dence intervals were utilized in the analysis. The estimates of the sociodemographic characteristics of the population were compared by t-test for two independent samples and the comparison of the other estimates, according to the type of survey, was performed using Poisson regression. RESULTS:No statistically signifi cant differences were found between the estimates obtained by the two surveys analyzed for overall prevalence of: overweight/obesity, smoking status, mammography in the prior year and Pap smear at least once in life. However, for the estimates of worse perceived health status, health plan affi liation, mammography at least once in life and Pap smear in the prior year, signifi cant differences were found, with a tendency to overestimate data from the telephone survey, except in the case of worse perceived health status. CONCLUSIONS:These fi ndings point to the need for further studies, which may contribute to a better understanding of the differences, given that telephone surveys can provide quick and essential information for monitoring modifi able risk factors for the assessment of interventions and to develop policies promoting health in Brazil.

Cigarette smoking among psychiatric patients in Brazil

“…Although there are few publications on smoking among patients with mental illness in Brazil, evidence suggests that smoking prevalence is higher among this group than in the general population: population based studies show that smoking prevalence was 21% in Pelotas (State of Rio Grande do Sul) 9 and 19% in Campinas (State of São Paulo) 10 , while among patients with severe psychiatric illness in São Paulo it was 59% 11 , almost three times higher.…”

Desigualdades sociodemográficas nos fatores de risco e proteção para doenças crônicas não transmissíveis: inquérito telefônico em Campinas, São Paulo

“…12 Entrevistas realizadas por telefone apresentam vantagens, frente aos diversos métodos de coleta de dados empregados em inquéritos, pela presteza, menor custo e elevada taxa de resposta. 4,13 No ano de 2008, o Ministério da Saúde selecionou o município de Campinas-SP para a realização do inquérito telefônico (Sistema de Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico -Vigitel) porque, no mesmo ano, seria realizado um inquérito domiciliar de saúde na cidade (Inquérito de Saúde no Município de Campinas -ISACamp), possibilitando comparações de alguns indicadores, obtidos a partir de questões semelhantes aplicadas em ambas as modalidades de inquérito. 13 Cabe ressaltar que os dados sobre os fatores de risco e proteção coletados por essa pesquisa ainda não foram divulgados em sua totalidade.…”

Risk and protection factors for cardiovascular diseases among adults of Cuiabá, Mato Grosso, Brazil

“…Another limitation refers to the validity of self-reported information, which may be influenced by the access to health services and memory bias. However, studies conducted to validate some indicators from VIGITEL were conducted in Brazil and showed agreement between the information reported in VIGITEL and the data reported in household surveys [43][44][45] . Finally, the analyzed period can also be considered as a limit for the study, considering that the evolution of the variables could be better established if the period of observation had been longer.…”
