Factors associated to smoking habit among older adults (The Bambuí Health and Aging Study)

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.

Prevalência da violência contra a mulher por parceiro íntimo em regiões do Brasil

OBJETIVO: Analisar os resultados do WHO Multi-country Study on Women´s Health and Domestic Violence sobre a prevalência da violência contra mulheres por parceiros íntimos encontrada no Brasil. MÉTODOS: Estudo transversal integrante do WHO Multi-country Study on Women's Health and Domestic Violence against women, realizado em dez países, entre 2000-2003. Em todos os locais foi utilizado questionário estruturado padronizado, construído para o estudo. Para conhecer contrastes internos a cada país, a maior cidade e uma região rural foram investigadas, sempre que factível. Foi selecionada amostra representativa da cidade de São Paulo e de 15 municípios da Zona da Mata de Pernambuco constituída por mulheres de 15 a 49 anos de idade. Foram incluídas 940 mulheres de São Paulo e 1.188 de Pernambuco, que tiveram parceria afetivo-sexual alguma vez na vida. A violência foi classificada nos tipos psicológica, física e sexual, sendo analisadas suas sobreposições, recorrência dos episódios, gravidade e época de ocorrência. RESULTADOS: Mulheres de São Paulo e Pernambuco relataram, respectivamente, ao menos uma vez na vida: violência psicológica (N=383; 41,8% e N=580; 48,9%), física (266; 27,2% e 401; 33,7%); sexual (95; 10,1% e 170; 14,3%). Houve sobreposição dos tipos de violência, que parece associada às formas mais graves de violência. A maior taxa da forma exclusiva foi, para São Paulo e Pernambuco, a da violência psicológica (N=164; 17,5% e N=206; 17,3%) e a menor da violência sexual (N=2;0,2% e 12; 1,0%) CONCLUSÕES: Os resultados mostram a violência como um fenômeno de alta freqüência. Os achados reiteram estudos internacionais anteriores quanto à grande magnitude e superposições das violências por parceiro íntimo.

Fatores associados à violência por parceiro íntimo em mulheres brasileiras

OBJETIVO: Estimar a prevalência e os fatores associados à violência física e/ou sexual por parceiro íntimo em diferentes contextos socioculturais. MÉTODOS: Estudo transversal, participante do WHO Multi-country Study on Women's Health and Domestic Violence against women, com amostra representativa de mulheres no município de São Paulo e Zona da Mata de Pernambuco, região com normas mais tradicionais de gênero. Foram entrevistadas no domicílio 940 mulheres de São Paulo e 1.188 da Zona da Mata, entre 2000-1, com idade entre 15 a 49 anos que tiveram parceria afetivo-sexual com homens alguma vez na vida. Foram construídos três conjuntos de fatores, correspondentes a blocos hierarquicamente ordenados: características sociodemográficas, familiares e aspectos referentes à autonomia/submissão feminina. Utilizou-se regressão logística hierárquica na análise dos fatores associados à violência por parceiro íntimo em cada local. RESULTADOS: Encontrou-se prevalência de 28,9% em São Paulo (IC 95% 26,0;31,8) e 36,9% (IC 95% 34,1;39,6) na Zona da Mata. Escolaridade até oito anos, violência física conjugal entre os pais da mulher, abuso sexual na infância, cinco ou mais gestações e problemas com a bebida mostraram-se associados à violência por parceiro íntimo em ambos locais. Autonomia financeira da mulher, união informal, idade e consentimento na primeira relação sexual mostraram-se associadas a maiores taxas apenas na Zona da Mata. As características socioeconômicas associadas no primeiro bloco foram mediadas por outros fatores no modelo final. CONCLUSÕES: Os achados mostram a relativização dos fatores socioeconômicos diante de outros, em especial os representantes de atributos de gênero. Nas duas localidades estudadas foram encontradas diferenças socioculturais que se refletiram nos fatores associados.

Edentulism and shortened dental arch in Brazilian elderly from the National Survey of Oral Health 2003

OBJECTIVE: To describe the distribution of edentulism and estimate the prevalence of functional dentition and shortened dental arch among elderly population. METHODS: A population-based epidemiological study was carried out with a sample of 5,349 respondents aged 65 to 74 years obtained from the 2002 and 2003 Brazilian Ministry of Health/Division of Oral Health survey database. The following variables were studied: gender; macroregion of residence; missing teeth; percentage that met the World Health Organization goal for oral health in the age group 65 to 74 years (50% having at least 20 natural teeth); presence of shortened dental arch; number of posterior occluding pairs of teeth. The Chi-square test assessed the association between categorical variables. The Kruskal-Wallis and Mann-Whitney tests were used to assess differences of mean between number of posterior occluding pairs teeth, macro-region and gender. RESULTS: The elderly population had an average of 5.49 teeth (SD: 7.93) with a median of 0. The proportion of completely edentulous respondents was 54.7%. Complete edentulism was 18.2% in the upper arch and 1.9% in the lower arch. The World Health Organization goal was achieved in 10% of all respondents studied. However, only 2.7% had acceptable masticatory function and aesthetics (having at least shortened dental arch) and a mean number of posterior occluding pairs of 6.94 (SD=2.97). There were significant differences of the percentage of respondents that met the World Health Organization goal and presence of shortened dental arch between men and women. There were differences in shortened dental arch between macroregions. CONCLUSIONS: The Brazilian epidemiological oral health survey showed high rate of edentulism and low rate of shortened dental arch in the elderly population studied, thus suggesting significant functional and aesthetic impairment in all Brazilian macroregions especially among women.

Religiousness and health-related quality of life of older adults

OBJECTIVE To examine whether religiousness mediates the relationship between sociodemographic factors, multimorbidity and health-related quality of life of older adults.METHODS This population-based cross-sectional study is part of the Survey on Health, Well-Being, and Aging (SABE). The sample was composed by 911 older adults from Sao Paulo, SP, Southeastern Brazil. Structural equation modeling was performed to assess the mediator effect of religiousness on the relationship between selected variables and health-related quality of life of older adults, with models for men and women. The independent variables were: age, education, family functioning and multimorbidity. The outcome variable was health-related quality of life of older adults, measured by SF-12 (physical and mental components). The mediator variables were organizational, non-organizational and intrinsic religiousness. Cronbach’s alpha values were: physical component = 0.85; mental component = 0.80; intrinsic religiousness = 0.89 and family APGAR (Adaptability, Partnership, Growth, Affection, and Resolve) = 0.91.RESULTS Higher levels of organizational and intrinsic religiousness were associated with better physical and mental components. Higher education, better family functioning and fewer diseases contributed directly to improved performance in physical and mental components, regardless of religiousness. For women, organizational religiousness mediated the relationship between age and physical (β = 2.401, p < 0.01) and mental (β = 1.663, p < 0.01) components. For men, intrinsic religiousness mediated the relationship between education and mental component (β = 7.158, p < 0.01).CONCLUSIONS Organizational and intrinsic religiousness had a beneficial effect on the relationship between age, education and health-related quality of life of these older adults.

Serological markers and risk factors for hepatitis B and C viruses in patients infected with human immunodeficiency virus

Both hepatitis B and hepatitis C viruses (HBV and HCV) infection are common in HIV-infected individuals as a result of shared risk factors for acquisition. A serological study for HBV and HCV was performed in 251 HIV-positive individuals from Medellín, Colombia. A qualitative RT-PCR for HCV was done in 90 patients with CD4+ T-cell count < 150 per mm³. Serological markers for HBV infection were present in 97 (38.6%) patients. Thirty six of them (37.1%) had isolated anti-HBc. A multivariate analysis indicated that the following risk factors were significantly associated with the presence of these markers: age (OR = 1.05, 95% CI: 1.01-1.08), pediculosis pubis (OR = 1.83, 95% CI: 1.01-3.33), men who have sex with men and women (OR = 3.23, 95% CI: 1.46-7.13) and men who have sex only with men (OR = 3.73, 95% CI: 1.58-8.78). The same analysis restricted to women showed syphilis as the only significant risk factor. Thus, HBV infection was considerably associated with high risk sexual behavior. HCV was present in only two (0.8%) of HIV patients. Both of them were positive by RT-PCR and anti-HCV. This low frequency of HIV/HCV coinfection was probably due to the uncommon intravenous drug abuse in this population. The frequent finding of isolated anti-HBc warrants molecular approaches to rule out the presence of cryptic HBV infection.

Frequency of hepatitis B immunity and occupational exposures to body fluids among brazilian medical students at a public university

In the present study the frequencies of immunity against hepatitis B (HB) and of potentially contaminating accidents among medical students of a Brazilian public university were evaluated. Of all the 400 students who should have been immunized, 303 (75.7%), 66.3% of whom were women, answered an anonymous, self-administered questionnaire. Serum anti-HBs were determined in 205 of them and titers > 10 UI/L were considered to be protective. A total of 86.8% of students had received three doses of HB vaccine. The frequency of immunity among women (96.4%) was higher (p = 0.04) than that among men (87.7%). Among those who did not have immunity, 12/13 (92.3%) had been vaccinated before entering medical school. Only 11% of the students with complete vaccination had previously verified serological response to the vaccine. A total of 23.6% reported having been somehow exposed to blood or secretions. Among final-year students, this frequency was 45.0%, being similar among men (47.8%) and women (43.2%). Of all these accidents, 57.7% were due to body fluids coming in contact with mucosa and 42.3% due to cut and puncture accidents. The results from this study show that: 1) the frequency of immunity against HB is high among the evaluated medical students, although verification of response to vaccination is not a concern for them; 2) anti-HBs titers should be verified after complete vaccination and on a regular basis, especially by men; and 3) the frequency of potentially contaminating accidents is high.

Frequency of metabolic syndrome and the food intake patterns in adults living in a rural area of Brazil

INTRODUCTION: Metabolic syndrome (MetS), a risk factor for atherosclerosis and coronary heart disease, is related to an inadequate food intake pattern. Its incidence is increasing among Brazilian adults, including those living in rural areas. Our aim was not only to describe the frequency of MetS in adults with or without MetS but also to compare their food intake pattern as assessed by the healthy eating index (HEI) and serum albumin and C reactive protein (CRP) levels. METHODS: Men and women (n = 246) living in a small village in Brazil were included. MetS was characterized according to the adult treatment panel (ATP III) criteria. Groups were compared by chi-square, student t or Mann-Whitney tests. RESULTS: MetS was diagnosed in 15.4% of the cases. The MetS group showed higher CRP (1.8±1.2 vs. 1.0±0.9 mg/dl) and lower albumin (4.3±0.3 vs. 4.4±0.3 g/dl) serum levels compared to the control group. Additionally, the MetS group showed lower scores (median[range]) in the HEI compared to the control group (53.5[31.2-78.1] vs 58[29.7-89.5], respectively). The MetS group also had decreased scores for total fat and daily variety of food intake. CONCLUSIONS: The results suggest that adults with MetS displayed chronic mild inflammation and a poorer food intake pattern than the control group.

Paracoccidioidomycosis in a western Brazilian Amazon State: Clinical-epidemiologic profile and spatial distribution of the disease

Introduction: Paracoccidioidomycosis (PCM) is a systemic infection caused by the fungus Paracoccidioides brasiliensis. PCM is considered one of the most important systemic mycoses in Latin America. Methods: This is a clinical, epidemiological, retrospective, quantitative study of PCM cases in patients attending the National Health Service in the State of Rondônia in 1997-2012. The examined variables included sex, age group, year of diagnosis, education level, profession, place of residence, diagnostic test, prior treatment, medication used, comorbidities and case progress. Results: During the study period, 2,163 PCM cases were registered in Rondônia, and the mean annual incidence was 9.4/100,000 people. The municipalities with the highest rates were located in the southeastern region of Rondônia, and the towns of Pimenteiras do Oeste and Espigão do Oeste had the highest rates in the state, which were 39.1/100,000 and 37.4/100,000 people, respectively. Among all cases, 90.2% and 9.8% were observed in men and women, respectively, and most cases (58.2%) were observed in patients aged between 40 and 59 years. Itraconazole was used to treat 91.6% (1,771) of cases, followed by sulfamethoxazole in combination with trimethoprim (4.4% [85] of cases). One hundred thirty-one (6%) patients died. Conclusions: The State of Rondônia has a high incidence of PCM, and the municipalities in the southeastern region of the state were found to have the highest incidence rates of this disease. Our findings suggest that Rondônia is the state in the northern region with the highest mortality rate for PCM.

Hepatitis virus and hepatocellular carcinoma in Brazil: a report from the State of Espírito Santo

IntroductionFew studies have examined hepatocellular carcinoma (HCC) in Brazil, and the incidence and risk factors for this type of malignancy vary greatly geographically. In this paper, we report several risk factors associated with HCC diagnosed at the University Hospital in Vitória, ES, Brazil.MethodsWe reviewed 274 cases of HCC (January 1993 to December 2011) in which hepatitis B (HBV) and C (HCV) virus infection and chronic alcoholism were investigated. A diagnosis of hepatocellular carcinoma was confirmed by histology or by the presence of a characteristic pattern on imaging.ResultsHCC with associated liver cirrhosis was noted in 85.4% of cases. The mean ages of men and women were 56.6 years and 57.5 years, respectively. The male-to-female ratio was 5.8:1. Associated risk factors included the following: HBV, 37.6% (alone, 23.4%; associated with chronic alcoholism, 14.2%); HCV, 22.6% (alone, 13.5%; associated with chronic alcoholism, 9.1%), chronic alcoholism, 17.1%, non-alcoholic steatohepatitis, 2.6% and cryptogenic, 19.3%. The male-to-female ratio was higher in cases associated with HBV or chronic alcoholism compared with HCV-associated or cryptogenic cases. In 40 cases without associated cirrhosis, the male-to-female ratio and mean age were lower than those in cirrhosis-associated cases.ConclusionsThese results demonstrate that the main risk factor associated with HCC in the State of Espírito Santo is HBV. Chronic alcoholism is an important etiological factor, alone or in association with HBV or HCV infection.

Voiding dysfunction and urodynamic abnormalities in elderly patients

Lower urinary tract dysfunction is a major cause of morbidity and decreased quality of life in elderly men and women. With the progressive aging of the population, it is important to understand common micturitional disorders that may occur in this population. Most urinary problems in the elderly are multifactorial in origin, demanding a comprehensive assessment of the lower urinary tract organs, functional impairments, and concurrent medical diseases. Urodynamics is a highly valuable tool in the investigation of elderly patients with lower urinary tract symptoms. Urodynamic tests are not always necessary, being indicated after excluding potentially reversible conditions outside the urinary tract that may be causing or contributing to the symptoms. Although urodynamic tests may reveal common diagnoses such as bladder outlet obstruction and stress urinary incontinence in the elderly population, findings such as detrusor overactivity and impaired detrusor contractility are common and have important prognostic and therapeutic implications. The purpose of this article is to describe common urologic problems in the elderly and review the indications for and clinical aspects of urodynamic studies in these conditions.

Diet and medication in the treatment of hyperuricemia in hypertensive patients

OBJECTIVE: To evaluate the effects of diet and medication, either isolated or associated, on serum levels of uric acid in patients with hyperuricemia. METHODS: We studied patients from the Hypertension Unit of the University of Goias who had hyperuricemia (men > or = 8.5mg/dL and women > or = 7.5mg/dL). We divided the patients into three groups: G1 (low purine diet), G2 (low purine diet + medication), and G3 (medication only). Patients received allopurinol, 150mg/day titrated up to 300mg/dL when necessary. Patients were evaluated with regards to their lifestyles (diet, smoking, physical, activity, alcohol consumption), uric acid, blood pressure, use of medication, body mass index, cholesterol, and triglyceride. Follow-up took place in weeks 0 (M1), 6 (M2), 12 (M3) during the intervention and in week 36(M4) after the study was completed. RESULTS: Fifty-five patients participated in the study, 31 women, mean age 54.4±10.6 years, body mass index 28.6±3.9kg/m². A similar reduction (p<0.001) in uric acid levels occurred in the three intervention groups. In week 36 (M4), after 24 weeks without intervention, a tendency toward elevation of uricemia was noted in G2 and G3, and a continuous drop in uricemia was noted in G1. No significant modifications were observed in the other variables analyzed. CONCLUSION: Considering the cost x benefit relationship, a diet low in purine should be the 1st therapeutic option for controlling hyperuricemia in patients with similar characteristic to the ones presented in this study.

Trends in death from circulatory diseases in Brazil between 1979 and 1996

OBJECTIVE: To analyze the trends in mortality due to circulatory diseases in men and women aged > or = 30 years in Brazil from 1979 to 1996. METHODS: We analyzed population count data obtained from the IBGE Foundation and mortality data obtained from the System of Information on Mortality of the DATASUS of the Ministry of Health. RESULTS: Circulatory diseases, ischemic heart disease, and cerebrovascular disease were the major causes of death in men and women in Brazil. The standardized age coefficient for circulatory disease in men aged > or = 30 years ranged from 620 to 506 deaths/100,000 inhabitants and in women from 483 to 383 deaths/100,000 inhabitants for the years 1979 and 1996, respectively. In men, the mean coefficient for the period was 586.25 deaths with a significant trend towards a decrease (P<0.001) and a decline of 8.25 deaths/year. In women, the mean coefficient for the period was 439.58 deaths, a significant trend towards a decrease (P<0.001) and a rate of decline of 7.53 deaths/year. The same significant trend towards a decrease in death (P<0.001) was observed for ischemic heart disease and cerebrovascular disease. Risk of death from these causes was always higher for men of any age group (P<0.001). Cerebrovascular disease was the primary cause of death in women. CONCLUSION: Although circulatory diseases have been the major cause of mortality in men and women in the Brazilian population, with a greater participation by cerebrovascular diseases, a trend towards a decrease in the risk of death from these causes is being observed.

Male Gender and Arterial Hypertension are Plaque Predictors at Coronary Computed Tomography Angiography

Background: Systemic Arterial Hypertension (SAH) is one of the main risk factors for Coronary Artery Disease (CAD), in addition to male gender. Differences in coronary artery lesions between hypertensive and normotensive individuals of both genders at the Coronary Computed Tomography Angiography (CCTA) have not been clearly determined. Objective: To Investigate the calcium score (CS), CAD extent and characteristics of coronary plaques at CCTA in men and women with and without SAH. Methods: Prospective cross-sectional study of 509 patients undergoing CCTA for CAD diagnosis and risk stratification, from November 2011 to December 2012, at Instituto de Cardiologia Dante Pazzanese. Individuals were stratified according to gender and subdivided according to the presence (HT +) or absence (HT-) of SAH. Results: HT+ women were older (62.3 ± 10.2 vs 57.8 ± 12.8, p = 0.01). As for the assessment of CAD extent, the HT+ individuals of both genders had significant CAD, although multivessel disease is more frequent in HT + men. The regression analysis for significant CAD showed that age and male gender were the determinant factors of multivessel disease and CS ≥ 100. Plaque type analysis showed that SAH was a predictive risk factor for partially calcified plaques (OR = 3.9). Conclusion: Hypertensive men had multivessel disease more often than women. Male gender was a determinant factor of significant CAD, multivessel disease, CS ≥ 100 and calcified and partially calcified plaques, whereas SAH was predictive of partially calcified plaques.

Genital manifestations of schistosomiasis mansoni in women: important but neglected

Egg-induced lesions in the upper and the lower female reproductive tract are important complications of the infection with Schistosoma mansoni. The understanding of the pathophysiology and pathology of genital lesions is only rudimentary, simple and reliable diagnostic tools are not at hand, epidemiological data do not exist and how to treat best the women affected, is not known. In view of recent advances in the understanding of genital lesions induced by S. haematobium the existing literature is critically analysized and possible consequences of female genital schistosomiasis are outlined. We estimate that 6 to 27 % girls and women with intestinal schistosomiasis, at least temporarily, suffer from pathology induced by eggs sequestered somewhere in their genital organs. This is a mattern of concern and warrants more research into the epidemiology, pathology, diagnosis and therapy of this disease entity.
