O acesso aos serviços de saúde é uma das características importantes e um desafio ao Sistema Único de Saúde. Este estudo tem por objetivo compreender as dificuldades dos homens com DST no acesso à consulta. Trata-se de uma pesquisa qualitativa com homens atendidos em uma unidade de referência de DST, na cidade de Fortaleza, Ceará, Brasil, em novembro de 2003. A mesma foi aprovada pelo Comitê de Ética e utilizou a técnica de análise de conteúdo na análise e interpretação dos resultados. As entrevistas centraram-se na categoria acesso. Os achados evidenciaram que os homens com DST enfrentam dificuldade no acesso à consulta, mesmo utilizando diferentes mecanismos para consegui-la. Os serviços são oferecidos em horários incompatíveis com a demanda. Este fato é agravado pela falta de planejamento do número de consultas e de profissionais disponíveis para o atendimento dos casos de DST. Concluímos que precisa haver um investimento maior em nível do SUS na melhoria do acesso à consulta para homens com DST e faz-se necessário que, do ponto de vista institucional, a oferta de serviços leve em consideração a demanda da população.

As hemoglobinopatias estão incluídas dentre as doenças hereditárias mais freqüentes nas populações humanas. Estudos realizados em diferentes regiões do Brasil têm demonstrado que as hemoglobinas anormais S e C são as mais prevalentes. Com o objetivo de investigar a prevalência de hemoglobinas anormais no período neonatal, foram analisadas 1.940 amostras de sangue de cordão umbilical provenientes de recém-nascidos de três maternidades da cidade de Natal, Rio Grande do Norte. Todas as amostras foram submetidas à eletroforese de hemoglobina em acetato de celulose utilizando tampão Tris-EDTA-Borato pH 8,5. As amostras que apresentaram hemoglobinas anormais foram submetidas à eletroforese em gel de ágar pH 6,2 para confirmação. Foram identificadas 37 (1,91%) amostras com hemoglobinas anormais, das quais 29 (1,50%) com traço falciforme (Hb FAS), 06 (0,31 %) com Hb C, uma (0,05 %) com anemia falciforme (Hb FS) e uma (0,05 %) apresentou Hb Bart's, sugerindo alfa talassemia. Os resultados encontrados evidenciam a necessidade de implantação da triagem de hemoglobinopatias em recém-nascidos na nossa população.

Descreve-se a mortalidade proporcional de dentistas residentes na cidade de São Paulo, entre 1980 e 2000, segundo causas de óbito, em busca de possíveis indicações de risco atribuíveis ao trabalho, com dados levantados na Fundação Sistema Estadual de Análise de Dados. A análise comparativa usou informações análogas para médicos e engenheiros. O estudo dos diferenciais de óbito segundo causa básica indicou a ausência de alterações significantes, apontando risco potencial de óbito aumentado para dentistas em relação a médicos e engenheiros. Os óbitos de dentistas não apresentaram piores indicadores para categorias globais e específicas de doenças infecciosas, neoplasias, suicídio, doenças do sistema nervoso central e do aparelho circulatório. Foi observada indicação de excesso sistemático de óbitos de engenheiros por causas externas em geral, por acidentes de trânsito, quedas acidentais e demais acidentes em particular. Registrou-se a ausência de discrepâncias significantes que apontassem para risco diferencial atribuível ao trabalho de dentistas. Essa observação sugere que a Odontologia pode ser considerada uma profissão segura, ao menos no que diz respeito à exposição a riscos sistemáticos de óbito.

O objetivo desta investigação foi identificar a prevalência da anemia e alguns de seus potenciais determinantes em 754 crianças de áreas urbanas de sete municípios na região do semi-árido baiano. Hemoglobina foi determinada em 745 crianças de um a 72 meses de idade. Para o grupo etário de seis a 72 meses um valor de hemoglobina < 11,0 g/dl identifica a anemia segundo recomendação da OMS enquanto o valor

This study aimed to analyze whether there is an association between intimate partner violence during pregnancy and time to return to sexual activity after childbirth in the BRISA cohort in São Luís, Maranhão State, Brazil, between 2010 and 2013. This is a longitudinal study conducted with 665 women. Intimate partner violence during pregnancy was measured using an instrument created and validated by the World Health Organization to measure violence against women. Time to return to sexual activity after childbirth was investigated using a structured questionnaire. Logistic regression models were used to analyze whether there is an association between intimate partner violence during pregnancy and time to return to sexual activity after childbirth. The prevalence of violence by an intimate partner during pregnancy was 24.06%. The prevalence of women who returned to sexual activity within 3 months after childbirth was 67.96%. When analyzing the association between exposure and outcome, no association was found in the crude model (OR = 0.88; 95%CI: 0.60-1.30), nor in the adjusted model (OR = 1.00; 95%CI: 0.61-1.63). The study results highlight the importance of providing comprehensive care to women, considering both physical and psychological aspects, since violence has a significant impact on several aspects of women's lives.

The study aimed to compare biomarkers in groups of adolescents classified simultaneously according to body mass index (BMI) and body fat percentage measured by air displacement plethysmography. This was a cross-sectional study with 533 adolescents 18 to 19 years of age in São Luís, Maranhão, Brazil. BMI was classified as adequate (< 25kg/m2) versus excess weight (≥ 25kg/m2). High body fat percentage was defined as ≥ 25% for males and ≥ 30% for females. The adolescents were classified in four groups: "normal weight" (adequate BMI and body fat percentage), "normal weight obese" (adequate BMI with high body fat percentage), "excess weight with adequate body fat percentage", and "excess weight with high body fat percentage". Girls showed higher proportions of "normal weight obesity" (15.6%) and "excess weight with high body fat percentage" (17.1%). "Normal weight obese" adolescents exhibited higher mean values for total cholesterol (172.5mg/dL) and LDL-cholesterol (103.5mg/dL). Those with "excess weight and high body fat percentage" showed lower mean HDL-cholesterol (43.2mg/dL) compared to the other groups, higher mean interleukin-6 (2.7pg/mL) than "normal weight" and "excess weight and adequate body fat percentage" adolescents, and higher median triglycerides (114.0mg/dL) and C-reactive protein (0.14ng/mL) than "normal weight" and "normal weight obese" adolescents. Those with "excess weight and adequate body fat percentage" exhibited the same C-reactive protein levels as those with "excess weight and high body fat percentage". Assessment of nutritional status by BMI alone is limited, since 6.8% of the adolescents presented high body fat percentage despite normal BMI, and those who were "normal weight obese" had two biomarkers that were worse than for adolescents with "excess weight and high body fat percentage".

This study estimated the percentages of incomplete immunization with new vaccines and old vaccines and associated factors in children 13 to 35 months of age belonging to a birth cohort in São Luís, the capital of Maranhão State, Brazil. The sample was probabilistic, with 3,076 children born in 2010. Information on vaccination was obtained from the Child's Health Card. The new vaccines, namely those introduced in 2010, were meningococcal C and 10-valent pneumococcal, and the old vaccines, or those already on the childhood immunization schedule, were BCG, hepatitis B, human rotavirus, polio, tetravalent (diphtheria, tetanus, pertussis, Haemophilus influenzae b), yellow fever, and triple viral (measles, mumps, rubella). The study used hierarchical modeling and Poisson regression with robust variance. Prevalence ratios (PR) and 95% confidence intervals (95%CI) were calculated. Incomplete immunization was higher with new vaccines (51.1%) than with old vaccines (33.2%). Children 25 to 35 months of age (PR = 1.27; 95%CI: 1.14-1.41) and those in economic classes D/E (PR = 1.20; 95%CI: 1.06-1.35) were only significantly associated with new vaccines; low maternal schooling (PR = 1.58; 95%CI: 1.21-2.06), unavailability of outpatient and/or hospital care for the child (PR = 1.20; 95%CI: 1.04-1.38), and unavailability of the vaccine in health services (PR: 1.28; 95%CI: 1.12-1.46) were only associated with old vaccines. Immunization strategies should consider the vulnerability of older preschool-age children and those belonging to classes D and E, especially when new vaccines are introduced, as well as children of mothers with low schooling. Strategies should also address problems with the availability of health services and vaccines.

The objective of this study was to investigate factors associated with intimate partner violence after disclosing the diagnosis of sexually transmissible diseases (STDs) in Fortaleza, Ceará State, Brazil. This cross-sectional study enrolled 221 individuals treated at STD clinics. Multivariate logistic regression was performed. A total of 28.1% of individuals committed some type of intimate partner violence after disclosure of the diagnosis. Committing intimate partner violence was associated with alcohol use (OR = 2.79; 95%CI: 1.25-6.22; p = 0.012), the partner having relations with someone else during the current relationship (OR = 4.71; 95%CI: 2.24-9.91; p = 0.000), a history of violence prior to the STD (OR = 2.87; 95%CI: 1.22-6.73; p = 0.015), and having suffered violence after diagnosis of the STD (OR = 6.53; 95%CI: 3.06-13.93; p = 0.000). Intimate partner violence following disclosure of the STD signals that health professionals should identify patients' difficulties in revealing an STD diagnosis to their partners.

This cross-sectional study investigated the epidemiological profile of pregnant women with positive VDRL in Fortaleza, Ceará State, Brazil, in 2008. The study verified the proportion of pregnant women with syphilis that was classified as treated incorrectly according to Brazilian Ministry of Health guidelines, and assessed the reasons for inadequate treatment. Fifty-eight women who had given birth at five public maternity hospitals were interviewed consecutively following delivery. Data were also recovered from medical files and pregnancy cards. Sociodemographic and obstetric data and information related to the diagnosis and treatment of syphilis in both pregnant women and their partners were analyzed. Only three (5.2%; 95%CI: 1.8%-14.1%) pregnant women had received adequate treatment. The main reason for inadequate treatment was lack of partner treatment (88% of cases; 95%CI: 76.2%-94.4%). Medical care as currently provided does not guarantee the control of gestational syphilis in this sample.

This study aimed to assess hemoglobin level and anemia prevalence and their association with food-consumption and socioeconomic variables. A cross-sectional survey was conducted in the State of Pernambuco, Brazil, in 1997, using three-stage sampling which included 746 6-to-59-month-old children. Hemoglobin testing and a 24-hour food recall interview were performed. The anemia rate was 40.6% and was higher in the rural area and inversely proportional to age, income, and maternal schooling. Most children (88.9%) consumed cow's milk. Anemia was associated directly with the proportion of calories from cow's milk and indirectly with the iron level. Child's age, geographic area, per capita family income, maternal schooling, iron density (total, heme, and non-heme), and the proportion of calories from cow's milk in the diet were determinants for anemia.

Access to healthcare services is one of the important aspects of the Unified National Health System in Brazil, and the supply and management of such services is the responsibility of municipalities. This study focuses on difficulties faced by men with sexually transmitted diseases (STDs) in accessing appointments for treatment. This was a qualitative study of men treated at an STD clinic in Fortaleza, Ceará State, Brazil, in November 2003, using content analysis technique and interpretation of interviews, focusing on access as the category. Men with STDs encountered extensive difficulty in accessing medical appointments, even when they used different strategies for this purpose. Scheduling of services is incompatible with patients' available time. At the primary care level, the supply of appointments for STDs scarcely exists. More investment is needed in the Unified National Health System in order to improve access to appointments for men with STDs, and the supply of services should take the population's demand into account.

A cross-sectional study was conducted in a representative sample of 426 randomly selected first graders (ages 6 to 10 years) from public schools in Maceió, State of Alagoas, Brazil. The aim was to determine the prevalence of anemia, as well as its association with growth retardation. Data were collected from May to July 2000, and determination of hemoglobin (HGB) employed an STKS Coulter counter. Two cut-off points were used to classify anemia, both established by the World Health Organization: HGB < 11.5g/dl and HGB < 12.0g/dl. The indicators height/age (H/A), weight/age (W/A), and weight/height (W/H) below -2.0 standard deviations from the NCHS reference were diagnosed as growth retardation. Prevalence of anemia was 9.9% when HGB < 11.5g/dl was used, and 25.4% when the cut-off point was HGB < 12.0g/dl. Growth retardation was detected in 6.2% of children according to H/A, 4.0% for W/A, and 3.0% for W/H. There was no statistically significant association between the variables in the study. These findings confirm results of previous surveys where prevalence of anemia was much higher than that of growth retardation. The severe consequences of anemia in this age group justify the implementation of broad public policies to overcome this nutritional deficiency.
