Implementation of the Family Health Program and socio-spatial exclusion in the city of São Paulo, Brazil

The present article analyzes the implementation of the Family Health Program (FHP) in S?o Paulo, Brazil, taking as its reference the occupation of the city's space, characterized by strong socio-spatial segregation. The population coverage and consolidation achieved by the FHP and the partner institutions' legal and institutional formats were identified in 96 Administrative Districts (AD). The study then proceeded to stratify these ADs beginning with their position in a ranked social exclusion map. ADs were classified in five groups. Based on these results, a typology was produced in the FHP implementation in this capital city of the State of S?o Paulo. Clearly distinct patterns were identified when the ADs were ranked for exclusion/inclusion. FHP implementation was effective within the peripheral ADs, especially those in Group 1, indicating pressure for the Municipal Health Secretariat to comply with its discourse, which had assumed the FHP as a health care model to be implemented throughout the city, at least reaching the entire low-income population.     

Prevalence of tobacco use in individuals with severe mental illnesses, São Paulo, Brazil

OBJECTIVE: To analyze the prevalence of cigarette smoking in individuals with severe mental illnesses in a large urban centre of a middle income country. METHODS: Cross-sectional study carried out in S?o Paulo. The sample (N=192) comprised individuals diagnosed with severe mental illnesses who had contact with public psychiatric care services from September to November 1997 and were aged between 18 and 65 years. Prevalence of daily tobacco smoking in the 12 months previous to the interview and characteristics associated were studied. RESULTS: Out of 192 subjects with severe mental illnesses interviewed, 115 (59.9%; 95% CI: 52.6%; 66.9%) reported smoking cigarettes on a daily basis. Male gender, marital status separated or widowed, irregular use of neuroleptic drugs and history of ten or more psychiatric admissions were independently associated with cigarette smoking. CONCLUSIONS: The prevalence of cigarette smoking in the present sample was higher than that found in the general Brazilian population. Mental care services should implement non-smoking policies and mental health providers need to help patients with severe mental illness who want to quit smoking.     

Prevalence of hypovitaminosis a in children of peripheral districts of Campinas São Paulo, Brazil

The prevalence of hypovitaminosis A among children of the peripheral districts of the city of Campinas, S o Paulo, Brazil, was estimated by determining serum retinol levels by High Performance Liquid Chromatography (HPLC) in a sample of 131 children aged between three and ten years, between April 1991 and February 1992. A prevalence of 17.6% and retinol concentrations in the range of 0.35 to 0.70 micromol/L were found (CI=11.1-24.1; 95%), indicating the existence of public health risk Ophthalmological examinations, however, failed to detect any cases of xerophthalmy. Additional characterization of the sample was obtained from 341 children. The per capita income of the average household was surprisingly high for low-income areas. According to FAO-WHO standards, food consumption was adequate only for protein (133.96%). Adequacy levels were low for energy (87.76%) and particularly for vitamin A (66.13%) and iron (42.14%). Height for-age and weight-for-height anthropometric indices revealed that many children were located below -1 standard deviation.     

Asthma mortality in the city of São Paulo,Brazil

OBJECTIVE: To quantify and compare asthma mortality rates as the main cause of death, taking into consideration the following variables: sex, age and seasonality. METHODS: Data was collected from all death certificates coded 493 of people aged 5 to 34 years in the periods of 1983-5 and 1993-5 in the city of S?o Paulo, SP, Brazil. Data analysis was performed by directly comparing death rates and identifying the odds ratio trend and directly comparing the numbers of asthma deaths. RESULTS: There was no increase in asthma mortality rates for the study periods. There was no difference between men and women. A greater number of deaths in the age group 20 to 34 years were observed. Seasonality was more evident in the first period studied. CONCLUSIONS: Differing from reports in other countries, the results did not show any increase in asthma mortality rates, The variable sex didn't seem to interfere with mortality. Deaths are more frequent among young adults, and their risk may be 9 times greater than that of young children. Deterioration of social and economic issues and health care services and even climatic changes may have been implicated in the absence of seasonality as a risk factor for asthma mortality. The disease by itself is not considered by many health professionals as critical in order to explain the chain of events that lead to death.     

Prevalence of Cryptosporidium sp. in institutionalized dogs in the city of São Paulo, Brazil

OBJECTIVE: Dogs play an important role as infection source of human cryptosporidiosis. The objective of the study was to determine the prevalence of Cryptosporidium sp. in dogs as well as to compare two techniques of fecal analysis. METHODS: Four-hundred and fifty canine fecal samples from the city of S?o Paulo were analyzed between 2003 and 2004. Fecal samples were randomly selected from dogs housed in a university veterinary hospital (group 1, n=200) and private kennels (group 2, n=250). The detection of Cryptosporidium was performed using modified Ziehl-Neelsen staining and Polymerase Chain Reaction (PCR) technique. Statistical analysis was performed using the two-tailed test of significance at 5% confidence interval (z critical=+/-1.645). RESULTS: Only Cryptosporidium parvum oocysts were found. The prevalences found by light microscopy examination and PCR techniques were 8.8% and 9.5%, respectively. Young animals showed a lower frequency (5.5%) compared to adults (10.1%). There was no statistically significant difference in Cryptosporidium prevalence between males and females. CONCLUSIONS: The prevalence of C. parvum in the canine population studied was similar to that one found in the literature and affects equally males and females. The use of PCR allowed the detection of more positive cases than light microscopy.     

Prevalence of a set of risk factors for chronic diseases in the city of São Paulo, Brazil

OBJECTIVE: To estimate the prevalence of a set of risk factors for non-transmissible chronic diseases and compare it to that found 15-16 years ago in a similar survey. METHODS: A cross-sectional household survey was carried out comprising a random sample of people aged 15-59 years in the city of S?o Paulo between 2001 and 2002. The total of 2,103 people answered a questionnaire and had their blood pressure, weight, height, waist and hip circumferences measured. For a third of these participants, their total cholesterol, HDL-cholesterol, triglycerides and glucose levels were determined. RESULTS: The total age-adjusted prevalences in the study age group were as follows: smoking, 22.6%; uncontrolled blood pressure, 24.3%; obesity, 13.7%; increased waist circumference, 19.7%; total cholesterol >or =240 mg/dL, 8.1%; HDL-cholesterol <40 mg/dL, 27.1%; triglycerides > or =200 mg/dL, 14.4%; and blood glucose > or =110 mg/dL, 6.8%. Smoking, uncontrolled blood pressure, high total cholesterol, low HDL-cholesterol and high triglycerides were significantly more prevalent in men than women. CONCLUSIONS: The prevalences of a set of risk factors for chronic diseases showed men to have a poorer condition than women. In comparison to the previous survey, the prevalence of uncontrolled blood pressure remained unchanged but the prevalence of smoking has significantly lowered.     

Seroprevalence of human parvovirus B19 in a suburban population in São Paulo, Brazil

OBJECTIVE: To analyze the prevalence of IgG antibodies to human parvovirus B19. METHODS: Cross-sectional study in a suburban community in S?o Paulo, Southeastern Brazil, between November 1990 and January 1991. Randomly selected (N=435) representative samples of sera were collected from healthy children older than 15 days old and adults up to 40 years old. IgG antibodies were detected using ELISA. RESULTS: High prevalence of IgG antibodies to B19 parvovirus was found in 87% of newborns. The prevalence of maternally derived IgG antibodies exponentially plunged up to the 19th month of age. Low prevalence of antibodies was found in the first 4 years of life, increasing up to 72% in those aged 31-40 years. It was estimated that the average age of first infection in this population is 21 +/- 7 years old and the optimal age for vaccination with a hypothetical vaccine would be 1 year of age. CONCLUSIONS: Parvovirus B19 IgG antibody prevalence was high in newborns and those aged 31-40 years. The analysis by age groups showed a pattern similar to that found in previous studies, i.e., low prevalence of infection in children that increases with age.     

The pediatrician's role in the Paidéia-Family Health Program in Campinas, São Paulo State, Brazil

Brazil is developing a Family Health Program in the Primary Health Care. The Family Health Program's team composition has been criticized as insufficient. One of the criticisms has been about the absence of the pediatrician. This study analyzed the experience of the city of Campinas, S?o Paulo State, which implemented this program with adaptations specifically with the presence of the pediatrician in its 140 teams. Using qualitative methodology and semi-structured interviews, pediatricians and ten family physicians teams were interviewed. The objective was to know their visions about their practice with children's primary health care, the role of each one and about the pediatrician's presence in the team. It was almost an unanimity about the importance of the pediatrician's participation in Primary Health Care, not as a specialty, but because of the improvement of the team's resolubility. Though, the pediatrician's work was considered too focused in the biomedical paradigm and in the office. There is a need for the pediatrician to have more engagement with the psychosocial aspects, the family and territory. It is essential the improvement of the training of pediatricians and family physicians to deal with the complex mission of the primary health care of nowadays.     

Utilization of community mental health services in the city of Santos, São Paulo, Brazil

To report on the clientele treated at community mental health services (CAPS) in the city of Santos, S?o Paulo, Brazil, a census was conducted of the patients examined at the services from June 1, 2001, to June 30, 2001. The patient's initial contact with the service was registered, and data were recorded on a standardized form, using the medical case history as a source of information. Among the 1,673 patients, average age was 46 years, 59.0% were female, 58.0% lived with their families, and mean duration of treatment was three years. Some 38.0% were schizophrenic, schizotypical, or in acute delusional states, 31.0% presented mood disorders, and 17.0% were neurotic. Treatment modalities included out-patient psychiatric (81.0%), individual (23.0%), group (13.0%), and psychosocial rehabilitation (4.3%). In Santos, CAPS treat all categories of mental disorders (and frequently those considered the most severe cases) expected at this type of service. The treatment model is that of an out-patient psychiatric clinic.     

Municipalization of vaccination in Ribeirão Preto, São Paulo, Brazil

The object of this study is the organization of activities in the vaccination program in Ribeir?o Preto, S?o Paulo, during the process of municipalization of health services, analyzing changes and estimating results. The methodology included a survey performed during supervisory visits and questionnaires with 20 nurses and 39 vaccination workers in all the vaccination rooms at the municipal primary health care unit in this city, a survey of storage conditions for immunobiological products at the municipal level and a questionnaire for the section head, and interviews with five health professionals responsible for vaccination at the State, regional, and municipal levels. It followed that since implementation of the so-called Integrated Health Actions proposal there has been an expansion of primary health care services, including vaccination services; there has also been a technical and administrative centralization of decisions involving vaccination activities, including training of human resources by the Municipal Epidemiological Surveillance division. The study points out that although this activity is dealt with carefully by those responsible for the State, municipal, and district levels, the same is not true at the local level.     

Culicidae (Diptera) in a dam construction area in the state of São Paulo, Brazil

OBJECTIVE: To describe the culicidae fauna in an area impacted by environmental changes caused by the construction of a dam. METHODS: The studied area was the Porto Primavera dam construction site in Southeastern Brazil. Monthly culicidae samples were taken in six exploratory sites in the pre-filling period and in one fixed site, one year before (1997-1998) and after the first filling (1999-2000). Adult mosquitoes were captured in the morning with an aspirator and with Shannon and CDC traps during the evening twilight period. Immature stages were captured using a ladle in the larger breeding sites and with a pipette in the smaller ones. RESULTS: In the pre-filling period of the dam, a total of 944 immature culicidae specimens, from ten species, were captured. A total of 14,932 adults were captured, including 7,031 mosquitoes from ten species in the exploratory points and 7,901 specimens from eight genera in the fixed site. After the first stage of the dam filling, the immature stages total was 1,201, from four genera, and the captured mosquitoes total was 5,912, from nine genera. There was a population reduction of the genera Aedes and Psorophora and an increase of the following species populations: Aedeomyia, Anopheles, Culex (Melanoconion), Mansonia and Uranotaenia. CONCLUSIONS: The environmental changes caused due to the construction of the Porto Primavera Dam contributed to an increase in the population density of some culicidae vectors, causing a nuisance and the potential risk of the transmission of pathogens to humans.     

Evaluation of effectivenness of prenatal assistance in a Family Health Unit in a city of the São Paulo State

Considering the importance of prenatal care quality to reduce maternal and perinatal morbidity and mortality, the aim of this study was to evaluate quality in the assistance to low-risk pregnant women by means of quality indicators stated by the Health Ministry. This is an evaluating, quantitative and retrospective study carried out in a Prenatal Service in a Family Health Unit in a city in the state of S?o Paulo. The results showed that the Family Health Program provides a quality prenatal assistance and that the link established between the Unit professionals and the Health Community Agents with pregnant women is imperative for the adherence to the Prenatal Assistance Program.     

Prevalence of dental caries in schoolchildren in the rural area of Itapetininga, São Paulo State, Brazil

The present study is an attempt to characterize dental needs of the rural population in Itapetininga, S?o Paulo State, Brazil. One single dentist examined 291 children ages 5 and 12 years in rural schools, adopting WHO criteria for oral health surveys. Parents reported their children's socioeconomic characteristics and habits. Non-primary data gathered by the Brazilian health authority supplied information regarding the schoolchildren in the urban area of the town. Caries indices ranked as follows: dmft = 2.63 (5-year-old children) and DMFT = 2.45 (12-year-old children). The decayed component comprised 85.6% of the dmft and 34.2% of the DMFT, indicating limited utilization of dental treatment by children with decayed deciduous teeth. Caries prevalence was higher in rural schoolchildren than in their urban counterparts. Analysis of the results aims to improve planning of dental care.     

Early Infant Morbidity in the City of São Paulo, Brazil

Background

Early infant morbidities may produce adverse outcomes in subsequent life. A low Apgar score is a convenient measure of early infant morbidity. We study determinants of early infant morbidity (sex, plurality, mode of delivery, prior losses, gestational age, prenatal care and birth weight, parity and maternal age, race, maternal education and community development) for the 1998-birth cohort, City of São Paulo, Brazil.

Methods

This study identified all deliveries that took place in the City of São Paulo during 1998. Information was extracted from 209,628 birth records. We used multivariate logistic regression to assess the effect of each independent variable on Apgar score less than seven at one minute and Apgar score less than seven at five minutes.

Results

Low birth weight, prematurity and community development were found to be strong predictors of morbidity. Maternal education showed strong negative correlation with both Apgar scores. The negative correlations between maternal schooling and Apgar scores were observed after prenatal care, parity and maternal age were included in the model. Unmeasured proximate factors may thus be the true source of disparity between educational groups. Children of very young adolescent mothers had lower Apgar scores at one minute (but not at five minutes) than those born to mothers 15 to 19. Parity one or higher was associated with decreased odds of low Apgar scores. Cesarean section and operative delivery were associated with higher odds of early infant morbidity.

Conclusion

Education may allow mothers to have better care in the peripartum period. More educated mothers may be more likely to recognize certain morbidities through the pregnancy period and the monitoring of such morbidities yields better infant outcomes. Also, having less than seven prenatal care visits was found to predict early infant morbidity and one way to increase the use of such services is to focus on aspects of care that may lead to easier accessibility and continuity of prenatal care. Physicians should inform mothers about the risks associated with high number of children for a next infant and also about the risks for the infant associated with unnecessary cesarean sections. Special attention should be paid to adolescent mothers, since much of their increased risk is likely to be minimized by counseling.
