Health surveys and use of maternal and child health care services in three municipalities within the Sao Paulo metropolitan area

Objectives. To describe the changes in the use of maternal and child health care services by residents of three municipalities-Embu, Itapecerica da Serra, and Taboao da Serra-in the Sao Paulo metropolitan area, 12 years after the implementation of the Unified Health System (SUS) in Brazil, and to analyze the potential of population-based health care surveys as sources of data to evaluate these changes. Methods. Two population-based, cross-sectional surveys were carried out in 1990 and 2002 in municipalities located within the Sao Paulo metropolitan area. For children under 1 year of age, the two periods were compared in terms of outpatient services utilization and hospital admission; for the mothers, the periods were compared in terms of prenatal care and deliveries. In both surveys, stratified and multiple-stage conglomerate sampling was employed, with standardization of interview questions. Results. The most important changes observed were regarding the location of services used for prenatal care, deliveries, and hospitalization of children less than 1 year of age. There was a significant increase in the use of services in the surrounding region or hometown, and decrease in the utilization of services in the city of Sao Paulo (in 1990, 80% of deliveries and almost all admissions for children less than 1 year versus 32% and 46%, respectively, in 2002). The use of primary care units and 24-hour walk-in clinics also increased. All these changes reflect care provided by public resources. In the private sector, there was a decrease in direct payments and payments through company-paid health insurance and an increase in payments through self-paid health insurance. Conclusions. The major changes observed in the second survey occurred simultaneous to the changes that resulted from the implementation of the SUS. Population-based health surveys are adequate for analyzing and comparing the utilization of health care services at different times.

Asthma management and asthma control in Sao Paulo, Brazil and Uppsala, Sweden: a questionnaire-based comparison

The Global Initiative Against Asthma (GINA) was developed to meet the global challenge of asthma. GINA has been adopted in most countries and comparison of asthma management in different parts of the world may be of help when assessing the global dissemination of the guideline. The overall goals in GINA include that asthma patients should be free of symptoms, acute asthma attacks and activity limitations. The aim of the present study was to compare asthma management and asthma control in Sao Paulo, Brazil and Uppsala, Sweden. Information was collected from asthmatics in Sao Paulo and Uppsala with a questionnaire. The questionnaire dealt with the following issues: symptoms, smoking, self-management, hospital visits, effect on school/work and medication. The Sao Paulo patients were more likely to have uncontrolled asthma (36% vs 13%, P < 0.001), having made emergency room visits (57% vs 29%, P < 0.001) and having lost days at school or work because of their asthma (46% vs 28%, P = 0.03) than the asthmatics from Uppsala. There were no difference in the use of inhaled corticosteroids, but the Brazilian patients were more likely to be using theophylline (18% vs 1%, P = 0.001) and less likely to be using long-acting beta-2 agonists (18% vs 37%, P < 0.001). We conclude that the level of asthma control was lower among the patients from Sao Paulo than Uppsala. Few of the patients in either city reached the goals set up by GINA. Improved asthma management may therefore lead to health-economic benefits in both locations. Please cite this paper as: Skorup P, Rizzo LV, Machado-Boman L and Janson C.

Childbirth self-efficacy inventory in Tanzania : a pilot study

Background. To give birth can be a stressful experience and women cope with thisstress in many different ways and have different personal outcomes. Self-efficacy orconfidence in ability to cope with labour can be considered as an important factoraffecting pregnant women’s motivation of normal childbirth and their interpretation ofthe childbirth event.The aim. The purpose of this study was to test the Chinese short form of theinstrument Childbirth self-efficacy instrument (CBSEI) in Tanzania, that measurepregnant women’s self-confidence and coping abilities during childbirth.Method. The Chinese short form of the CBSEI was used to pilot test the pregnantwomen’s confidence of childbirth to see if the questions were understood in theTanzanian culture. Besides this instrument socio-demographic data was collectedtogether with two open questions asking about attitudes and experiences of childbirth.The instrument was translated into Kiswahili. A sample of 60 pregnant women whowere visiting antenatal clinic (ANC) regularly were asked to participate and with helpfrom midwifes at two ANC places the questionnaires were filled out.Result. The result shows that the validity and reliability of the two subscales OE-16and EE-16 were established. The internal consistency reliability of the two subscaleswere high, suggesting that each of the subscale mean score provides a good overviewof self- reported belief in coping ability for childbirth.The results further show that the instrument, CBSEI in this pilot study is not able toidentify women who need extra support during childbirth.Conclusion. The reliability and validity of information presented in this pilot studysupport the use of the Chinese short form of the CBSEI as a research instrument in theTanzania culture. Further studies are recommended to get a wider understandingabout women’s coping abilities in a culture like Tanzania.

Factors associated with evidence-based practice among registered nurses in Sweden : a national cross-sectional study

Background: Evidence-based practice (EBP) is emphasized to increase the quality of care and patient safety. EBP is often described as a process consisting of distinct activities including, formulating questions, searching for information, compiling the appraised information, implementing evidence, and evaluating the resulting practice. To increase registered nurses' (RNs') practice of EBP, variables associated with such activities need to be explored. The aim of the study was to examine individual and organizational factors associated with EBP activities among RNs 2 years post graduation. Methods: A cross-sectional design based on a national sample of RNs was used. Data were collected in 2007 from a cohort of RNs, included in the Swedish Longitudinal Analyses of Nursing Education/Employment study. The sample consisted of 1256 RNs (response rate 76%). Of these 987 RNs worked in healthcare at the time of the data collection. Data was self-reported and collected through annual postal surveys. EBP activities were measured using six single items along with instruments measuring individual and work-related variables. Data were analyzed using logistic regression models. Results: Associated factors were identified for all six EBP activities. Capability beliefs regarding EBP was a significant factor for all six activities (OR = 2.6 - 7.3). Working in the care of older people was associated with a high extent of practicing four activities (OR = 1.7 - 2.2). Supportive leadership and high collective efficacy were associated with practicing three activities (OR = 1.4 - 2.0). Conclusions: To be successful in enhancing EBP among newly graduated RNs, strategies need to incorporate both individually and organizationally directed factors.

Effects of computer reminders on complications of peripheral venous catheters and nurses' adherence to a guideline in paediatric care : a cluster randomised study

BACKGROUND: Reminder systems in electronic patient records (EPR) have proven to affect both health care professionals' behaviour and patient outcomes. The aim of this cluster randomised trial was to investigate the effects of implementing a clinical practice guideline (CPG) for peripheral venous catheters (PVCs) in paediatric care in the format of reminders integrated in the EPRs, on PVC-related complications, and on registered nurses' (RNs') self-reported adherence to the guideline. An additional aim was to study the relationship between contextual factors and the outcomes of the intervention. METHODS: The study involved 12 inpatient units at a paediatric university hospital. The reminders included choice of PVC, hygiene, maintenance, and daily inspection of PVC site. Primary outcome was documented signs and symptoms of PVC-related complications at removal, retrieved from the EPR. Secondary outcome was RNs' adherence to a PVC guideline, collected through a questionnaire that also included RNs' perceived work context, as measured by the Alberta Context Tool. Units were allocated into two strata, based on occurrence of PVCs. A blinded simple draw of lots from each stratum randomised six units to the control and intervention groups, respectively. Units were not blinded. The intervention group included 626 PVCs at baseline and 618 post-intervention and the control group 724 PVCs at baseline and 674 post-intervention. RNs included at baseline were 212 (65.4 %) and 208 (71.5 %) post-intervention. RESULTS: No significant effect was found for the computer reminders on PVC-related complications nor on RNs' adherence to the guideline recommendations. The complication rate at baseline and post-intervention was 40.6 % (95 % confidence interval (CI) 36.7-44.5) and 41.9 % (95 % CI 38.0-45.8), for the intervention group and 40.3 % (95 % CI 36.8-44.0) and 46.9 % (95 % CI 43.1-50.7) for the control. In general, RNs' self-rated work context varied from moderately low to moderately high, indicating that conditions for a successful implementation to occur were less optimal. CONCLUSIONS: The reminders might have benefitted from being accompanied by a tailored intervention that targeted specific barriers, such as the low frequency of recorded reasons for removal, the low adherence to daily inspection of PVC sites, and the lack of regular feedback to the RNs.

Validação do questionário Internacional de Atividade Física (IPAQ) através da acelerometria em idosas

Physical activity is one of the main components of a healthy lifestyle, responsible for many health benefits. Despite being considered important for both disease prevention and health promotion there is high prevalence of sedentary behavior in the elderly population. Questionnaires are practical and feasible instruments for assessing levels of physical activity. However, they may have limitations in older age ranges. Accelerometers, movement sensors that make physical activity data more objective, emerge as reliable measuring devices. Aim: Determine the validity of the International Physical Activity Questionnaire (IPAQ) adapted for elderly with accelerometry in elderly women. Methods: 57 elderly women, with mean age of 66.05 ± 5.98 years who took part in hypertension control and physical activity incentive programs were assessed in relation to objective and subjective measures of physical activity. The accelerometer was used for 07 consecutive days, 24 hours per day before the IPAQ was applied. Data were analyzed using measures of central tendency and dispersion to characterize the sample according to variables collected. To check the validity of the data we used the Spearman correlation test, considering a significance level of p <0.05. Results: With respect to the categories of physical activity obtained by IPAQ, 46.4% developed moderate physical activity, followed by a high (30.3%) and low level (23.2%). There was a negative correlation only between self-reported time spent sitting and time spent on light activities as measured by accelerometry (r = - 0.408; p = 0.003) and mean activity level (counts/min) with physical activity levels evaluated by IPAQ (r = 0.297; p = 0.036). Conclusion: The IPAQ used in elderly women shows moderate to low validity levels according to accelerometry measures. Assessment of sedentary activities exhibited acceptable levels compared to accelerometry; however, moderate (r = 0.096; p > 0.05) to vigorous (r = 0.098; p > 0.05) activities were not correlated, demonstrating the inability of IPAQ to evaluate this type of activity in elderly women

Velocidade da marcha como preditor de fragilidade em uma amostra populacional de idosos brasileiros

Gait speed has been described as a predictive indicator of important adverse outcomes in older populations. Among the criteria to evaluate frailty, gait speed has been identified as the most reliable predictor of fragility, practical and low cost. Objective: This study assesses the discriminating capability of gait speed in determining the presence of fragility in the elderly community in northeast of Brazil. Method: We performed an observational analytic study with a transversal character with a sample of 391 community-living elders, aged 65 years or older, of both sexes, in the city of Santa Cruz-RN. Participants were interviewed using a multidimensional questionnaire to obtain sociodemographic information, physical-related and mental health-related information. The unintentional weight loss, muscle weakness, self-reported exhaustion, slow gait and low-physical activity were considered to evaluate the frailty syndrome. Gait velocity was measured as the time taken to walk the middle 4,6 meters of 8,6 meters (excluding 2 meters to warm-up phase and 2 meters to deceleration phase).We calculate the sensitivity and specificity of gait speed test in different cutoff points for the test run time, from which ROC curve was constructed as a measure of test predictive value to identify frail elders. The prevalence of frailty in Santa Cruz-RN was 17.1%. The gait speed test accuracy was 71%when speed is below 0,91m/s. Among women, the gait speed test accuracy was 80%(gait speed below 0.77m/s) and among men, the test accuracy was 86% (gait spend below 0,82%) (p<0,0001).Conclusion: our findings have clinical relevance when we consider that the detection of frailty presence by the gait speed test can be observed in elderly men and women by a simple, cheap and efficient exam

A eliminação do mosquito do dengue em ambientes residenciais: uma questão de cuidado ambiental?

Dengue is currently considered one of the most relevant public health problems worldwide. Studies indicate the surroundings of the houses as the preferred sites for the proliferation of Aedes aegypti. The residential areas are privileged environments for human development and contribute to the formation of the individual s identity and for the establishment of affective, social and cultural bonds. The purpose of this study was to investigate possible links between psychological indicators of pro-environmentalism and conservation status of residential backyards. Data collection was performed in 147 homes and methodological strategy involved the use of interview, the Scale of Ecocentric and Anthropocentric Environmentalism, Scale of Consideration of Future Consequences and a tool for environmental evaluation. It was found that the participants expressed as environmental practices the garbage recycling, besides they had the knowledge of how the transmission of dengue occurs. These residents showed ecofriendly motivated commitment: pro-environmentalist ecocentric and anthropocentric. In evaluating the backyard it was verified that the conservation conditions, in almost half of the homes, appeared as carelessness on the part of residents and those conditions are conducive to the proliferation of Aedes aegypti. The pro-environmentalists and guidance for the future identified by the scales were not associated with the conservation status of the backyards. However, it was found that the trends of reduction and stability of infestation levels are associated with self-reported environmental care. These results can contribute to the discussion and design of new mosquito control actions and practices of education and health information among the population

Health surveys and use of maternal and child health care services in three municipalities within the São Paulo metropolitan area

Validade de histórias ocupacionais de informantes secundários

OBJETIVO: Embora sejam freqüentes os estudos epidemiológicos trazendo informações ocupacionais obtidas em entrevistas com familiares de trabalhadores, há poucos trabalhos analisando a validade dessas informações, sendo nenhum deles realizados em países em desenvolvimento. Objetivou-se estudar a validade do uso de informações ocupacionais obtidas de informantes secundários em estudos epidemiológicos, pela análise de concordância entre histórias ocupacionais obtidas em entrevistas independentes com os próprios trabalhadores e seus familiares. MÉTODOS: A história ocupacional de trabalhadores, residentes no Município de Botucatu, SP, em 1998, foi obtida por entrevistas com os próprios trabalhadores e com os familiares próximos. Calcularam-se a sensibilidade e a especificidade das informações ocupacionais dos familiares, considerando-se padrão-ouro a informação do trabalhador. Avaliou-se a concordância dos pares de informação pelo coeficiente Kappa. RESULTADOS: Foram entrevistados 2.163 pares trabalhador/familiar. A sensibilidade da informação ocupacional dos familiares variou entre 77,5% (IC95%; 64,6% -- 90,4%) e 98,9% (97,3% -- 100,0%), enquanto a especificidade variou entre 96,9% (96,0% -- 97,7%) e 99,9% (99,7% -- 100,0%). O coeficiente Kappa para a concordância da informação ocupação principal, segundo as duas fontes, foi de 0,86 (0,85 -- 0,88). CONCLUSÕES: A utilização de informações ocupacionais obtidas de informantes secundários, se tratadas como variáveis categóricas, tem validade. Utilizando-se informações relativas a tempos acumulados de trabalho, concluiu-se que informantes secundários subestimam os tempos de exposição quando comparados com os próprios trabalhadores.

Vacinação contra influenza em idosos por área de residência: prevalência e fatores associados

A vacinação contra influenza é a principal forma de prevenir e reduzir a morbidade e mortalidade associadas à doença entre os idosos e grupos de risco. O objetivo deste estudo é determinar fatores demográficos, socioeconômicos, comportamentais e de saúde associados à vacinação, entre idosos residentes em diferentes áreas do Estado de São Paulo, no período de 2001 a 2002. Trata-se de um delineamento transversal de base populacional que considerou os idosos residentes em duas áreas do Estado: uma composta pelo município de Campinas e distrito do Butantã, na cidade de São Paulo, e outra pelos municípios de Taboão da Serra, Embu e Itapecerica da Serra (região metropolitana do município de São Paulo). A amostra foi composta por 849 e 641 indivíduos com 60 anos ou mais, residentes em tais localidades, respectivamente. Na análise bruta foram utilizadas razões de prevalência e intervalos de confiança de 95% e a análise multivariada foi realizada pela regressão de Poisson. A prevalência de vacinação auto-referida foi de 66,9% entre os residentes em Campinas e no distrito do Butantã e 67,6% naqueles das demais localidades. Após análise ajustada, para os idosos de Campinas e Butantã, apenas menor escolaridade (RP = 1,25; IC 95%: 1,02-1,54) esteve associada à vacinação. Já na área composta pelos municípios menos populosos, idade mais avançada (RP = 1,15; IC 95%: 1,02-1,31), hipertensão arterial (RP = 1,21; IC 95%: 1,02-1,45), diabetes (RP = 1,16; IC 95%: 1,01-1,33) e doença crônica de pulmão (RP = 1,30; IC 95%: 1,03-1,64) referidas, estiveram também associadas. Apesar de a prevalência de vacinação contra influenza entre os idosos das diversas localidades ser praticamente a mesma, pôde-se observar diferenças no perfil do idoso quanto à referência desse procedimento preventivo.

Prevalência de deficiência auditiva referida e causas atribuídas: um estudo de base populacional

Objetivou-se verificar a prevalência de deficiência auditiva referida pela população urbana de quatro localidades do Estado de São Paulo, Brasil, e estudar as causas atribuídas e variáveis sócio-demográficas. Foi realizado um estudo transversal de base populacional com dados referentes à população com 12 anos ou mais residente nas quatro localidades, em 2001 e 2002. Participaram 5.250 sujeitos selecionados por amostragem probabilística, estratificada e selecionada por conglomerados, em dois estágios. A análise dos dados foi exploratória, incluindo análise bivariada e regressão logística múltipla. A prevalência de deficiência auditiva foi 5,21%, mais acentuada nas faixas etárias acima de 59 anos (18,7%), que referiram doenças nos 15 dias anteriores à entrevista (8,4%), com transtorno mental comum (8,85%) e que fizeram uso de medicamentos nos últimos 3 dias (8,45%). O estudo dos fatores que se associam à deficiência auditiva direcionam intervenções de saúde para que atendam as reais necessidades da população, principalmente na atenção primária. Há necessidade de mais estudos populacionais com enfoque na audição, visto que esta é uma área escassa de publicações no Brasil.

Diabetes mellitus: fatores associados à prevalência em idosos, medidas e práticas de controle e uso dos serviços de saúde em São Paulo, Brasil

Este estudo analisa os fatores associados à prevalência de diabetes segundo as variáveis demográficas socioeconômicas, condição de saúde e estilo de vida, o uso dos serviços de saúde e medidas e práticas de controle entre 872 idosos residentes na cidade de São Paulo, Brasil. A prevalência de diabetes referida foi de 17,9%, valor acima do encontrado na população adulta. A maior prevalência de diabetes foi verificada entre idosos que relataram sua saúde como ruim/muito ruim, os que nunca beberam ou não bebem mais, os viúvos e entre os que se hospitalizaram pelo menos uma vez no último ano. Dentre os idosos, 69,9% procuraram o serviço rotineiramente por causa do diabetes e 96,1% foram atendidos no serviço que procuraram. Há falta de informação, conhecimento e a utilização de medidas de controle ainda é insuficiente entre os idosos. Fazem-se necessárias políticas de saúde com foco na capacitação de profissionais e na orientação familiar, e que incentivem mudanças no estilo de vida dos idosos.
