Prevalência de quedas em idosos e fatores associados

OBJECTIVE: Increased life expectancy and consequent growth of the elderly population has resulted in changes in the epidemiological morbidity and mortality profile. In the group of chronic degenerative diseases, falls are a prevailing among those preventable conditions. The objective of the study was to assess prevalence of falls in the elderly and to describe their associated factors. METHODS: Cross-sectional study comprising 4,003 elderly subjects (aged 65 years or more) living in areas covered by primary health care in 41 municipalities with more than 100,000 inhabitants from seven Brazilian states. Wald test for heterogeneity and linear trend were used for the estimation of significance level. Adjusted analysis was conducted using Poisson regression and adjusted prevalence rates were estimated. RESULTS: The prevalence of falls among the elderly was 34.8%, significantly higher in women (40.1%) than men. Among those who experienced falls, 12.1% had fractures as a consequence. The prevalence of falls was directly associated with older age, sedentary lifestyle, self-perception of poor health and more chronic drug use reported. The prevalence of falls was similar in the elderly attending different care services (basic health care units and Family Health Program). CONCLUSIONS: The prevalence of falls among elderly could be reduced through actions targeting their needs in health care units, especially regarding preventable associated factors.

Use of pacifiers and breastfeeding duration

Pacifiers are widely used in many developing countries. Although their use is not recommended for breastfeeding infants, there have been no published reports on the association between pacifier use and risk of early weaning. In a study of 354 infants in Brazil, mothers were asked about pacifier use at age 1 month, duration of breastfeeding, and introduction of other foods. Among 249 children still breastfed at 1 month, the risk that a child would be weaned at any age between 1 and 24 months was higher in pacifier users than in non-users (hazard ratio 3.0, 95% CI 2.0-4.6). The association remained even after adjustment for the childs age, sex, birthweight, socioeconomic status, and age at introduction of bottle-feeding.

Health information technology in primary health care in developing countries: a literature review

This paper explores the debate and initiatives concerning the use of information technology (IT) in primary health care in developing countries. The literature from 1992-2002 was identified from searches of the MEDLINE, Latin American and Caribbean Health Science Literature Database (LILACS), Cochrane Library and Web of Science databases. The search identified 884 references, 350 of which were classified according to the scheme described by the Pan American Health Organization (PAHO). For the analysis of advantages, problems and perspectives of IT applications and systems, 52 articles were selected according to their potential contribution to the primary health-care processes in non-developed countries. These included: 10 on electronic patient registries (EPR), 22 on process and programmatic action evaluation and management systems (PPAEM) and 20 on clinical decision-support systems (CDS). The main advantages, limitations and perspectives are discussed.

Fatores de risco para mortalidade perinatal em Pelotas, RS, 1993

INTRODUCTION Although there was a considerable reduction in infant mortality in Pelotas, Rio Grande do Sul in the last decade, its perinatal causes were reduced only by 28%. The associated factors of these causes were analysed. MATERIAL AND METHOD All hospital births and perinatal deaths were assessed by daily visits to all the maternity hospitals in the city, throughout 1993 and including the first week of 1994. RESULTS The perinatal mortality rate was 22.1 per thousand births. The multivariate analysis showed the following risk factors: low socioeconomic level, male sex and maternal age above 35 years. Among multigravidae women, the fetal mortality rate was significantly increased for mothers with a previously low birthweight and a previous stillbirth. For early neonatal mortality the risk was significantly increased by a smaller number of antenatal visits than 5 and low birthweight. CONCLUSIONS Main risk factors for perinatal mortality: low socioeconomic level, maternal age above 35 years and male sex. For early neonatal mortality the risk was significantly increased by a smaller number of antenatal visits than 5 and low birthweight.INTRODUCTION: Although there was a considerable reduction in infant mortality in Pelotas, Rio Grande do Sul in the last decade, its perinatal causes were reduced only by 28%.

Determinantes da desnutrição infantil em uma população de baixa renda: um modelo de análise hierarquizado

To investigate the determinants of malnutrition among low-income children, the effects of socioeconomic, environmental, reproductive, morbidity, child care, birthweight and breastfeeding variables on stunting and wasting were studied. All 354 children below two years of age living in two urban slum areas of Pelotas, southern Brazil, were included. The multivariate analyses took into account the hierarchical structure of the risk factors for each type of deficit. Variables selected as significant on a given level of the model were considered as risk factors, even if their statistical significance was subsequently lost when hierarchically inferior variables were included. The final model for stunting included the variables education and presence of the father, maternal education and employment, birthweight and age. For wasting, the variables selected were the number of household appliances, birth interval, housing conditions, borough, birthweight, age, gender and previous hospitalizations.

Stressful life events and minor psychiatric disorders : An estimate of the population attributable fraction in a Brazilian community-based study

Objective: A population-based survey was conducted in Pelotas, southern Brazil, to assess the specific and the combined contribution of life events and socioeconomic factors on the overall prevalence of minor psychiatric disorders (MPD). Methods: The study covered a representative sample of the population aged fifteen years or older living in the urban area of the city. Using multi-stage sampling, a total of thirty census tracts and 600 households were selected. A standardized questionnaire assessed the presence of MPD (using the Self-Reporting Questionnaire—SRQ-20), the occurrence of life events (death of a relative, a relative with a chronic disease, loss of employment, divorce, migration, accident, and robbery/assault), and socioeconomic factors. Results: The prevalence of MPD was 22.7 percent (17.9% males and 26.5% females) and increased with age. Significant linear relationships with education and income were observed: the less education and income, the higher the prevalence of MPD. All life events, except migration and accident, were positively associated with MPD. People who experienced divorce in the last year had a prevalence of MPD three times higher than those who had not. The likelihood of MPD increased linearly with the number of life events. The highest proportion of Population Attributable Fraction for any life events was 24 percent. Conclusions: These data suggest that life events can explain a substantial proportion of MPD and with socioeconomic factors may be related to the onset of MPD.

Estudo longitudinal da população materno-infantil da região urbana do Sul do Brasil, 1993: aspectos metodológicos e resultados preliminares

All babies born in the hospitals of the city of Pelotas, Brazil, in 1982 were studied soon after delivery and followed up prospectively during the first years of their lives. In 1993, this study was repeated with a similar methodology, with the aim of assessing eventual changes in the level of maternal and child health. All five maternity hospitals in the city were visited daily and the 5,304 babies born included in the study. They were weighed and measured, and their gestational age was assessed using the Dubowitz method. Their mothers were examined and interviewed regarding a large number of risk factors. The mortality of these children was studied through the surveillance of all hospitals, cemeteries and death registries, and all hospital admissions were also recorded. Two nested case-control studies were carried out to assess risk factors for mortality and hospital morbidity. A systematic sample of 655 children were examined at home at one and three months of age, and these infants, as well as another sample of 805 children including all low-birthweight babies were also examined at the ages of six and twelve months. Their psychomotor development was also assessed. Losses to follow-up were only 6.6% at twelve months. Relative to the 1982 indicators, perinatal mortality fell by about 30% and infant mortality by almost 50%. The median duration of breastfeeding increased from 3.1 to 4.0 months. On the other hand, there was little change in the prevalences of low birthweight or of length for age at twelve months. The article that refers this abstract describes the methodology of the study and forthcoming publications will present detailed results.

Prevalence of falls in elderly in Brazil: a countrywide analysis

We conducted a cross-sectional study of a sample of 6,616 elderly living in urban areas of 100 municipalities in 23 Brazilian states, who responded to questions on the occurrence of falls in the 12 months prior to the interview, and occurrence of fractures due to the falls. The prevalence of falls among the elderly was 27.6% (95%CI: 26.5-28.7). Among those reporting falls, 11% had suffered fractures as a result. Of the elderly, 36% had received guidance about the precautions necessary to prevent falls, and about 1% had required surgery. Falls were associated with female gender, older age, low socioeconomic status, obesity and sedentary lifestyles. The prevalence of falls differed significantly between the North and other regions of Brazil. The study shows a high prevalence of falls, and underlines the need for preventive strategies targeting modifiable risk factors.

Estudo transversal sobre saúde mental de agricultores da Serra Gaúcha (Brasil)

OBJETIVO: Considerando a escassez de estudos rurais de base populacional, buscou-se avaliar as associacoes entre caracteristicas do trabalho rural e a ocorrencia de morbidade psiquiatrica menor- MPM. METODOS: Utilizando delineamento transversal, estudaram-se 1.282 agricultores de 446 estabelecimentos. As informacoes foram coletadas por entrevista direta, a partir da percepcao do trabalhador. O indice de Kappa foi adotado para controle de qualidade. Caracterizaram-se as condicoes produtivas, dados sociodemograficos e indicadores de saude mental. RESULTADOS: A prevalencia de MPM afetou 37,5% dos agricultores. As prevalencias foram maiores entre produtores de feijao e menores entre os de maca. Encontrou-se risco aumentado nos estabelecimentos de 26 a 50 ha, e risco reduzido associado a maior mecanizacao e aumento de escolaridade. A ocorrencia de intoxicacao por agrotoxicos mostrou forte associacao com MPM, embora nao se possa definir a direcao dessa associacao. CONCLUSOES: Os resultados alertam para a dimensao dos problemas e para a urgencia de medidas que visem a proteger a saude dos agricultores.

Trabalho rural e intoxicações por agrotóxicos

Pesticide use is intensive in Brazilian agriculture. Population-based studies on the characteristics of pesticide use and pesticide poisoning are scarce. This study describes the profile of occupational exposure and pesticide poisoning incidence. Farm characteristics and pesticide occupational exposure were evaluated using a cross-sectional design. Among 1,379 farmers/ farm workers, annual incidence of pesticide poisoning was 2.2 episodes per 100 exposed. Based on Poisson regression, applying pesticide, reentering crop fields after spraying, and working with pesticides on more than one farm were the types of exposure that presented a positive correlation with pesticide poisoning. The results may be useful for planning activities aimed at reducing occupational pesticide poisoning among rural workers.
