Knowledge, attitude and practice of mammography among women users of public health services

OBJECTIVE: To evaluate knowledge, attitude and practice related to mammography among women users of local health services, identifying barriers to its performance. METHODS: A total of 663 women were interviewed at 13 local health centers in a city of Southeastern Brazil, in 2001. Interviewees were randomly selected at each center and they were representative from different socioeconomic conditions. The number of interviewees at each center was proportional to monthly mean appointments. For data analysis, answers were described as knowledge, attitude, practice and their respective adequacies and then they were correlated with control variables through the chi-square test. RESULTS: Only 7.4% of the interviewees had adequate knowledge on mammography, while 97.1% of women had an adequate attitude. The same was seen for the practice of mammography that was adequate in 35.7% of the cases. The main barrier to mammography was lack of referral by physicians working at the health center (81.8%). There was an association between adequacy of attitude and five years or more of education and being married. There was also an association between adequacy of mammography practice and being employed and family income up to four minimum wages. CONCLUSIONS: Women users of local health services had no adequate knowledge and practice related to mammography despite having an adequate attitude about this exam.

HIV testing among pregnant women in Brazil: rates and predictors

OBJECTIVE: To assess rates of offering and uptake of HIV testing and their predictors among women who attended prenatal care. METHODS: A population-based cross-sectional study was conducted among postpartum women (N=2,234) who attended at least one prenatal care visit in 12 cities. Independent and probabilistic samples were selected in the cities studied. Sociodemographic data, information about prenatal care and access to HIV prevention interventions during the current pregnancy were collected. Bivariate and multivariate analyses were carried out to assess independent effects of the covariates on offering and uptake of HIV testing. Data collection took place between November 1999 and April 2000. RESULTS: Overall, 77.5% of the women reported undergoing HIV testing during the current pregnancy. Offering of HIV testing was positively associated with: previous knowledge about prevention of mother-to-child transmission of HIV; higher number of prenatal care visits; higher level of education and being white. HIV testing acceptance rate was 92.5%. CONCLUSIONS: The study results indicate that dissemination of information about prevention of mother-to-child transmission among women may contribute to increasing HIV testing coverage during pregnancy. Non-white women with lower level of education should be prioritized. Strategies to increase attendance of vulnerable women to prenatal care and to raise awareness among health care workers are of utmost importance.

Evidence of inadequate docosahexaenoic acid status in Brazilian pregnant and lactating women

Recently published data concerning dietary intake of fat and food sources of (n-3) long-chain polyunsaturated fatty acids (LCPUFA) in Brazil are reviewed together with data on biochemical indices of PUFA status during pregnancy and lactation and PUFA composition of breast milk in Brazilian adolescents and adults. Potential inadequacies of docosahexaenoic acid (DHA) status among Brazilian pregnant and lactating women have not yet been thoroughly evaluated. The data reviewed show that dietary intake of food sources of n-3 LCPUFA is low and possibly deficient in Brazil, and that biochemical indices of maternal DHA status and breast milk DHA content are low compared to the international literature. These data indicate inadequate DHA status among Brazilian women during pregnancy and lactation, but this evidence needs confirmation through comprehensive and specific population-based studies.

Risk factors for osteoporotic fractures and low bone density in pre and postmenopausal women

OBJECTIVE: To estimate the prevalence and analyze risk factors associated to osteoporosis and low-trauma fracture in women. METHODS: Cross-sectional study including a total of 4,332 women older than 40 attending primary care services in the Greater São Paulo, Southeastern Brazil, between 2004 and 2007. Anthropometrical and gynecological data and information about lifestyle habits, previous fracture, medical history, food intake and physical activity were obtained through individual quantitative interviews. Low-trauma fracture was defined as that resulting from a fall from standing height or less in individuals 50 years or older. Multiple logistic regression models were designed having osteoporotic fracture and bone mineral density (BMD) as the dependent variables and all other parameters as the independent ones. The significance level was set at p<0.05. RESULTS: The prevalence of osteoporosis and osteoporotic fractures was 33% and 11.5%, respectively. The main risk factors associated with low bone mass were age (OR=1.07; 95% CI: 1.06;1.08), time since menopause (OR=2.16; 95% CI: 1.49;3.14), previous fracture (OR=2.62; 95% CI: 2.08;3.29) and current smoking (OR=1.45; 95% CI: 1.13;1.85). BMI (OR=0.88; 95% CI: 0.86;0.89), regular physical activity (OR=0.78; 95% CI: 0.65;0.94) and hormone replacement therapy (OR=0.43; 95% CI: 0.33;0.56) had a protective effect on bone mass. Risk factors significantly associated with osteoporotic fractures were age (OR=1.05; 95% CI: 1.04;1.06), time since menopause (OR=4.12; 95% CI: 1.79;9.48), familial history of hip fracture (OR=3.59; 95% CI: 2.88;4.47) and low BMD (OR=2.28; 95% CI: 1.85;2.82). CONCLUSIONS: Advanced age, menopause, low-trauma fracture and current smoking are major risk factors associated with low BMD and osteoporotic fracture. The clinical use of these parameters to identify women at higher risk for fractures might be a reasonable strategy to improve the management of osteoporosis.

Efeitos respiratórios da exposição ao talco industrial em ex-trabalhadores de mineração

OBJETIVO: Avaliar efeitos respiratórios tardios da inalação ocupacional de talco contaminado por asbesto. MÉTODOS: Análise de série de casos de 29 ex-trabalhadores de mineração de talco contaminado com asbestos provenientes de Carandaí, MG, atendidos no Centro de Referência Estadual de Saúde do Trabalhador de Minas Gerais em 2004-2005. Os ex-trabalhadores foram submetidos a anamnese clínico-ocupacional, radiografia de tórax e espirometria. Foi criado um escore de exposição que, multiplicado pela duração, originou um índice de exposição cumulativa ao talco. Para verificar a associação do índice de exposição cumulativa com a presença de alterações radiológicas, sugestivas de pneumoconiose e/ou alterações pleurais, foi ajustado um modelo de regressão logística exata. RESULTADOS: Todos os ex-trabalhadores eram homens, com média de idade de 48,2 anos. Nas radiografias de tórax foram encontradas alterações pleurais em três deles, opacidades parenquimatosas compatíveis com pneumoconiose em um e suspeita em seis. Alterações espirométricas ocorreram em três. A regressão logística apontou odds ratio de 1,059 (IC 95%: 1,012;1,125) para o índice acumulado, ou seja, cada unidade no índice resulta em um aumento de 5,9% na chance de apresentar alteração radiológica compatível ou suspeita de pneumoconiose. Em relação à mediana do tempo estimado de latência entre o início da exposição até o diagnóstico das placas pleurais, ocorreu diferença significativa (p = 0,013) entre os casos (27,0 anos) e não casos (14,3 anos). CONCLUSÕES: Os achados apontam a necessidade de controle clínico nos trabalhadores que foram expostos a asbesto, particularmente devido aos efeitos tardios da exposição a esse mineral.

Pregnancy rates and predictors in women with HIV/AIDS in Rio de Janeiro, Southeastern Brazil

OBJECTIVE: To assess incidence and predictors of first pregnancy among women with HIV/AIDS. METHODS: Prospective cohort study was conducted in Rio de Janeiro, southeastern Brazil, between 1996 and 2003. This study comprised 225 women with HIV/AIDS followed up until their first pregnancy or first censored event (hysterectomy, tubal ligation, menopause, 50 years of age, loss to follow-up, death or the end of December 2003). Pregnancy and abortion rates were estimated, and Cox proportional hazards models were used to identify baseline characteristics associated with pregnancy risk. RESULTS: The women were followed up for 565 person/years with a median follow-up of 3 years per women. The mean age was 32 years (SD: 7), and 54.7% were white. There were 60 pregnancies in 39 women, and 18 were terminated (induced abortions), accounting for a rate of 6.9% and 2.1% women/year, respectively. Repeated pregnancies occurred in 33.3% of the women (13/39). Higher pregnancy risk was seen among younger women (HR=3.42; 95%CI: 1.69;6.95) and those living with their partners (HR=1.89; 95%CI: 1.00;3.57). Lower pregnancy risk was associated with higher education level (HR=0.43; 95%CI: 0.19;0.99) and use of antiretroviral therapy (HR=061; 95%CI: 0.31;1.17). CONCLUSIONS: Lower pregnancy rates were found in our cohort than in the general population. Sociodemographic characteristics should be taken into consideration in the management of reproductive health in HIV-positive childbearing age women. Reproductive and family planning counseling must be incorporated into HIV/AIDS programs for women to help preventing HIV transmission to their partners and offspring.

Survival of a cohort of women with cervical cancer diagnosed in a Brazilian cancer center

OBJECTIVE: To assess overall survival of women with cervical cancer and describe prognostic factors associated. METHODS: A total of 3,341 cases of invasive cervical cancer diagnosed at the Brazilian Cancer Institute, Rio de Janeiro, southeastern Brazil, between 1999 and 2004 were selected. Clinical and pathological characteristics and follow-up data were collected. There were performed a survival analysis using Kaplan-Meier curves and a multivariate analysis through Cox model. RESULTS: Of all cases analyzed, 68.3% had locally advanced disease at the time of diagnosis. The 5-year overall survival was 48%. After multivariate analysis, tumor staging at diagnosis was the single variable significantly associated with prognosis (p<0.001). There was seen a dose-response relationship between mortality and clinical staging, ranging from 27.8 to 749.6 per 1,000 cases-year in women stage I and IV, respectively. CONCLUSIONS: The study showed that early detection through prevention programs is crucial to increase cervical cancer survival.

Fissura por crack: comportamentos e estratégias de controle de usuários e ex-usuários

OBJETIVO: Compreender a fissura do usuário de crack, bem como descrever os comportamentos desenvolvidos sob fissura e estratégias utilizadas para seu controle. PROCEDIMENTOS METODOLÓGICOS: Estudo qualitativo com amostra intencional por critérios de 40 usuários e ex-usuários de crack em São Paulo, SP, nos anos de 2007 e 2008. Os entrevistados foram recrutados pela técnica da bola de neve e submetidos à entrevista semi-estruturada em profundidade, até a saturação teórica. Após transcrição literal, seguiu-se a análise do conteúdo das entrevistas para elaboração de inferências e hipóteses alicerçadas nessas narrativas. ANÁLISE DOS RESULTADOS: Os entrevistados estavam igualmente distribuídos quanto ao sexo, possuíam idade entre 18 e 50 anos, abrangeram todos os níveis de escolaridade e a maior parte possuía poucos recursos financeiros. Além da fissura sentida na abstinência de crack e da fissura induzida por pistas ambientais e emocionais, constatou-se um tipo de fissura que faz parte do próprio efeito do crack. Esta última apareceu como forte fator mantenedor dos binges de consumo, que foram os maiores responsáveis pelo rebaixamento de valores do usuário, sujeitando-o a práticas arriscadas para a obtenção da droga. Os métodos mais citados para a obtenção de crack ou dinheiro para comprá-lo foram: prostituição, manipulação de pessoas, endividamento, troca de pertences por crack e roubo. Foram relatadas estratégias para o alívio da fissura e táticas farmacológicas e comportamentais para evitar o seu desenvolvimento, como: comer, ter relação sexual, jogar futebol, trabalhar, evitar o contexto social de uso de crack e usar drogas que causam sonolência. CONCLUSÕES: Os binges de consumo de crack são causados pela fissura induzida durante o uso da droga. As medidas criadas pelo próprio usuário para lidar com a sua fissura melhoram sua relação com o crack e podem ser ferramenta importante para o aprimoramento do tratamento.

Care cost for pregnant and parturient women with diabetes and mild hyperglycemia

OBJECTIVE: To compare inpatient and outpatient care costs for pregnant/parturient women with diabetes and mild hyperglycemia. METHODS: A prospective observational quantitative study was conducted in the Perinatal Diabetes Center in the city of Botucatu, Southeastern Brazil, between 2007 and 2008. Direct and indirect costs and disease-specific costs (medications and tests) were estimated. Thirty diet-treated pregnant women with diabetes were followed up on an outpatient basis, and 20 who required insulin therapy were hospitalized. RESULTS: The cost of diabetes disease (prenatal and delivery care) was US$ 3,311.84 for inpatients and US$ 1,366.04 for outpatients. CONCLUSIONS: Direct and indirect costs as well as total prenatal care cost were higher for diabetic inpatients while delivery care costs and delivery-postpartum hospitalization were similar. Prenatal and delivery-postpartum care costs were higher for these patients compared to those paid by Brazilian National Health System.

Metabolic alterations in pregnant women: gestational diabetes

Gestational diabetes mellitus (GDM) and controversy are old friends. The impact of GDM on maternal and fetal health has been increasingly recognized. Nevertheless, universal consensus on the diagnostic methods and thresholds has long been lacking. Published guidelines from major societies differ significantly from one another, with recommendations ranging from aggressive screening to no routine screening at all. As a result, real-world practice is equally varied. This article recaps the latest evidence-based recommendations for the diagnosis and classification of GDM. It reviews the current evidence base for intensive multidisciplinary treatment of GDM and provides recommendations for postpartum management to delay and/or prevent progression to type 2 diabetes.
