Abstract: the aim of this study was to verify smoking cessation rates and associated factors. the study was performed in greater metropolitan belo horizonte and the town of bambuí, both in the state of minas gerais, brazil. study participants included 13,261 and 1,018 adults (> 20 years), respectively, randomly selected among residents of each area. the smoking cessation rate was 40.6% (95%ci: 39.1-42.3) in greater metropolitan belo horizonte and 38.8% (95%ci: 34.4-43.1) in bambuí. in greater metropolitan belo horizonte, smoking cessation showed an independent and positive association with age (> 40 years), schooling (4-7 and > 8 years), number of chronic conditions (> 2), and number of medical visits in the previous year (1-3 and > 4), and a negative association with marital status (unmarried). bambuí showed an independent and positive association with age (> 40 years) and a negative association with number of hospitalizations in the previous year (> 2). the heterogeneity of factors associated with smoking cessation made it difficult to identify vulnerable groups in order to target prevention strategies. further research is important to elucidate this heterogeneity.

Peixoto,Sérgio Viana; Firmo,Josélia Oliveira Araújo; Lima-Costa,Maria Fernanda;
Revista de Saúde Pública , 2005, DOI: 10.1590/S0034-89102005000500008
Abstract: objective: to describe the characteristics and associated factors of the smoking habit among older adults. methods: a population-based study was carried out comprising 1,606 (92.2%) older adults (>60 years old) living in the bambuí town, southeastern brazil in 1997. data was obtained by means of interview and socio-demographic factors, health status, physical functioning, use of healthcare services and medication were considered. the multiple multinomial logistic regression was used to assess independent associations between smoking habits (current and former smokers) and the exploratory variables. results: the prevalence of current and past smoking was 31.4% and 40.2% among men, and 10.3% and 11.2% among women, respectively (p<0.001). among current smokers, men consumed a larger number of cigarettes per day and started the habit earlier than women. among men, current smoking presented independent and negative association with age (>80 years) and schooling (>8 years) and positive association with poor health perception and not being married. among women, independent and negative associations with current smoking were observed for age (75-79 and >80 years) and schooling (4-7 and >8 years). conclusions: smoking was a public health concern among older adults in the studied community, particularly for men. yet, in a low schooling population, a slightly higher level was a protective factor against smoking for both men and women. programs for reducing smoking in the elderly population should take these findings into consideration.

Revista de Saúde Pública , 2004,
Abstract: OBJETIVO: Determinar a validade da hipertens o auto-referida e seus determinantes em adultos residentes na comunidade. MéTODOS: Foi selecionada uma amostra aleatória simples de moradores da cidade de Bambuí, Estado de Minas Gerais, com 18 anos de idade ou mais. Três medidas de press o arterial foram realizadas em 970 indivíduos, que correspondiam a 89,3% dos selecionados. A sensibilidade, especificidade e os valores preditivos positivo e negativo da hipertens o auto-referida foram calculados em rela o à hipertens o (média da press o arterial >90 ou >140 mmHg e/ou uso atual de medicamentos para hipertens o). RESULTADOS: A sensibilidade e a especificidade da hipertens o auto-referida foram 72,1% (IC 95%: 69,3-75,0) e 86,4% (IC 95%: 84,3-88,6), respectivamente. Sua prevalência foi 27,2% (IC 95%: 24,4-30,1), sendo razoavelmente semelhante à da hipertens o (23,3%; IC 95%: 20,7-26,1%). A validade da hipertens o auto-referida foi maior entre mulheres, entre aqueles com idade igual a 40-59 e >60 anos, entre os que haviam visitado médicos mais recentemente (<2 anos) e entre os que apresentavam maior índice de massa corporal (>25 kg/m2). CONCLUS ES: Os resultados mostram que a hipertens o auto-referida é um indicador apropriado da prevalência da hipertens o arterial, mesmo em uma popula o residente fora de grandes centros urbanos, e que os seus determinantes s o semelhantes ao observado em países desenvolvidos.

Abstract: O objetivo deste trabalho foi determinar a prevalência do tabagismo e verificar os fatores associados a este hábito entre idosos (> 60 anos). O estudo foi conduzido na Regi o Metropolitana de Belo Horizonte e na Cidade de Bambuí, ambas localizadas em Minas Gerais, Brasil. Foram selecionados 1.774 idosos na Regi o Metropolitana e 1.742 em Bambuí. Na Regi o Metropolitana, a prevalência de tabagismo atual e passado foi de 19,6% e 39,2% entre os homens, e 8,1% e 14,1% entre as mulheres, respectivamente. Em Bambuí, os dados correspondentes foram 31,4% e 40,2% entre os homens, e 10,3% e 11,2% entre as mulheres, respectivamente. Na Regi o Metropolitana, os indicadores de pior condi o de saúde e pior capacidade funcional apresentaram associa es significantes com o tabagismo passado, mas estas associa es n o foram observadas em Bambuí. Entre os fumantes atuais, as associa es pesquisadas n o foram consistentes. Estes resultados mostram a grande heterogeneidade dos fatores associados ao tabagismo, como observado em países desenvolvidos. As estratégias para a redu o do tabagismo nessa popula o devem considerar esta ausência de associa o entre sinais e sintomas e o hábito de fumar.

Cadernos de Saúde Pública , 2011, DOI: 10.1590/S0102-311X2011001500010
Abstract: the aim of this study was to estimate physical activity energy expenditure among older adults. the study comprised 1,585 residents in bambuí, minas gerais state, brazil, aged > 60 years (91% of the town's total elderly), and examined the frequency and duration of 23 types of physical activity among them. median energy expenditure was 975 met.min/week (1,195.8 among men and 803.1 among women), declining significantly with age in both sexes. the prevalence of sedentary lifestyles (< 450 met.min/week) was 31.2%. unhurried walking accounted for about 1/3 of total energy expenditure. multivariate analysis based on ordinal logistic regression showed inverse associations between energy expenditure and age and hospitalizations in both sexes. among men, inverse associations were observed with smoking, number of chronic diseases and number of medical appointments. these results emphasize the need for effective strategies to increase physical activity in older elderly, and underscore the high prevalence of walking in this group.
A influência de respondente substituto na percep??o da saúde de idosos: um estudo baseado na Pesquisa Nacional por Amostra de Domicílios (1998, 2003) e na coorte de Bambuí, Minas Gerais, Brasil

Cadernos de Saúde Pública , 2007, DOI: 10.1590/S0102-311X2007000800016
Abstract: this study was developed to examine whether the use of a proxy respondent influences the distribution and factors associated with health perception among older adults, as well as the mortality relative risk. the study included 28,943 and 35,040 participants from the brazilian national household survey (pnad) in 1998 and 2003, respectively, and 1,606 members of the cohort from bambuí, minas gerais, brazil. the results showed that use of proxy in the pnad 1998 and 2003 did not modify the distribution of health perception or associated factors. the 5-year mortality rate ratio among cohort participants was higher in direct interviews with seniors (rr = 2.40) as compared to those answered by proxies (rr = 1.28), but the direction of the association was the same. these results indicate that health perception data from the pnad can be used regardless of who answers the interview and that the association between worse health perception and mortality persisted even when perception was inferred from a proxy.

Abstract: objective: to assess the validity of self-reported diabetes and its determinants in the elderly. methods: cross-sectional study including 1,492 subjects aged > 60 years, which corresponds to 86% of all residents in this age group living in the municipality of bambuí, southeastern brazil, in 1997. the validity of self-reported diabetes was assessed comparing to diabetes mellitus defined by medical criteria (fasting glucose > 126 mg/dl or current treatment). multivariate analysis was carried out to assess factors independently associated with sensitivity and specificity. results: the prevalence of diabetes mellitus and self-reported diabetes were 14.5% and 11.7%, respectively. sensitivity and specificity of self-reported diabetes were 57.1% (95% ci: 50.3;63.8) and 96.9% (95% ci: 94.7;97.0), respectively. medical visits in the previous two years (pr=3.78), as well as 1_3 (pr=1.90) and > 4 years (pr=1.55) of schooling were positively and independently associated with sensitivity. medical visits in the previous two years (pr= 0.96) and female sex (pr = 0.97) were negatively and independently associated with specificity. conclusions: the study results indicated that self-reported diabetes should not be either used to estimate the prevalence of diabetes mellitus or to identify individuals with the disease in the study population. schooling and medical visits were determinants of the elderly awareness of being diabetics, indicating that these modifiable characteristics may play a role in secondary and tertiary prevention.

Cadernos de Saúde Pública , 2011, DOI: 10.1590/S0102-311X2011001500013
Abstract: we examined for cohort differences in hypertension control between participants in the bambuí cohort study of aging of aging born 1916-1926 and 1927-1937. participants included hypertensive elderly aged 71-81 at baseline (n = 313) and at 11th wave follow up (n = 484). prevalence of hypertension awareness (70.9% and 81.2%, respectively), median medical appointments in previous 12 months (2 and 3, respectively) and antihypertensive drug use (74.4% and 90.7% respectively) increased significantly from older to younger cohort. however, prevalence of appropriately controlled hypertension among those treated (< 140/< 90mmhg) was similar in both cohorts (44.6% and 40.1%, p = 0.255). multivariate analysis returned schooling as the only factor independently associated with appropriately controlled hypertension. despite increased medical appointments and drug use in the recent cohort, the prevalence of appropriately controlled hypertension remained as low as in the older cohort.
