This paper focuses on prevalence of nutritional status (Body Mass Index, BMI) in social groups in greater metropolitan S?o Paulo, in Southeastern Brazil. The population was stratified in four socioeconomic groups. Prevalence of malnutrition (BMI<18.5kg/m2), low body mass (BMI<20.0kg/m2), and overweight (BMI>25.0kg/m2) and obesity (BMI(30.0kg/m2) were calculated. Prevalence of malnutrition was 3.9% in men and 6.2% in women. Prevalence of overweight ranged from 27.5% to 34.1% in men and from 25.8% to 43.6% in women. Obesity ranged from 2.5% to 11.1% in men and from 7.1% to 20.5 in women. Prevalence of overweight and obesity was greater among women than men (p<0.01). In relation to excess weight (BMI>25.0kgm/2), the study showed that prevalence in men was 43, 51, 35, and 30% for strata I, II, III, and IV, respectively. Among women, prevalence was 12, 61, 55 and 46% for strata I, II, III, and IV, respectively. In women there were an abrupt increase in excess weight just before 40 years of age. A high percentage of overweight and obesity was observed in all population groups. 相似文献

This study reports the nutritional status of children attending daycare centers in the Municipality of S?o Paulo, Brazil. A representative sample of 827 children under 84 months of age was evaluated. Anthropometric measurements and information on socioeconomic characteristics and morbidity were collected. The most prevalent nutritional deficit was stunting (7.0%; 95%CI: 3.60-10.40). Univariate analysis showed a significant association between stunting and age (< 24 months), OR = 2.10 (95%CI: 1.11-3.98); diarrhea one month prior to the data collection, OR = 2.84 (95%CI: 1.42-5.66); mother's or caregiver's schooling (< 3 years), OR = 3.87 (95%CI: 1.10-13.68); number of household members (> 7), OR = 3.02(95%CI: 1.46-6.22); and number of siblings (> 2) OR = 4.81 (95%CI: 1.72-13.44). In the multivariate analysis, only diarrhea one month prior to the data collection, OR = 2.54 (95%CI: 1.20-5.38) and > 2 siblings, OR = 7.40 (95%CI: 2.20-24.93), remained associated with stunting. 相似文献

The article presents preliminary data from a prospective investigation in a sample of healthy 14-17-year-old students from a technical school in Sao Paulo, Brazil. Ninety-six Tanner stage 5 and thirty-one Tanner stage 4 adolescents were evaluated: testicular volume was measured using a Prader orchidometer, and semen analysis was performed according to standard procedures. Median testicular volume was 20.0 ml among Tanner 5 students and 15.0 ml in Tanner 4 students in both the right and left testes. No significant differences were found in sperm volume or motility. Median concentration was 66.0 million/ml for Tanner 5 and 47.0 million/ml for Tanner 4 subjects. Morphological patterns showed abnormal forms in 81.9% of Tanner 5 and 93.6% of Tanner 4 adolescents. Oligospermia (sperm concentration < 5 million/ml) was observed in 7.3% of Tanner stage 5 and 12.9% of Tanner stage 4 individuals. Azoospermia was observed in 3 students (1.8%), with counts less than 1.0 in 8 students (4.8%). The authors discuss the observed results, analyzing the potential implications arising from biological development and potential environmental exposures. 相似文献

This study focused on prevailing concepts in society concerning adolescents' health problems and needs. Based on concerns in the field of Collective Health in relation to public policies for social protection, the study attempted to grasp the public school perspective concerning these issues. The study's theoretical reference was the social determination of the health-disease process and the view that health needs are translated into demands for changes in the harmful processes resulting from relations in the production process. Data were gathered through interviews with pedagogical coordinators and focus groups with adolescents in public schools from the Raposo Tavares School District (Municipality of S o Paulo). The results showed that the participants recognized: (1) the sphere of social determinants at the base of adolescents' health problems and (2) in addition to disease processes, a set of social problems impacting the health-disease process, highlighting drug use and violence. Health needs are translated as demands for cross-sector public social policies. 相似文献

OBJECTIVE: To develop a food frequency questionnaire for adolescents (AFFQ) and demonstrate its relative validity. DESIGN: The final version of the AFFQ was composed of 76 food items previously identified according to their contribution in nutrients and overall importance within the eating habits of this population group. The validation study, which was undertaken during a 6 month period (June to November 1999), was administered to a sample of 79 who answered at least three 24 h dietary recalls (R24 h) applied at intervals of 45 days and one AFFQ at the end of the study. Applying the paired t-test and calculating Pearson correlation coefficients on nutrient data, differences in the mean of nutrients were obtained. Correlation coefficients between the mean energy-adjusted nutrients computed by the two methods were calculated, and correction was made for within-person variability. Agreement was evaluated by distribution of the adolescents according to quartiles of consumption. LOCUS: A public school within the metropolitan region of S?o Paulo city. RESULTS: A high variability in the dietary intake of adolescents was observed, with high rates of variability for cholesterol, retinal and vitamin C. The Pearson correlation coefficients, after being adjusted and corrected for variability, ranged from 0.10 to 0.72 among females and from 0.16 and 0.91 among males. The mean correlation coefficient for the entire group was 0.52. CONCLUSIONS: These results indicate that the AFFQ provides a potentially reliable scale for categorizing individuals by level of past intake of most nutrients, excluding retinol and iron. 相似文献

OBJECTIVE: To analyze the association between dietary patterns and oral cancer. METHODS: The study, part of a Latin American multicenter hospital-based case-control study, was conducted in S?o Paulo, Southeastern Brazil, between November 1998 and March 2002 and included 366 incident cases of oral cancer and 469 controls, frequency-matched with cases by sex and age. Dietary data were collected using a food frequency questionnaire. The risk associated with the intake of food groups defined a posteriori, through factor analysis (called factors), was assessed. The first factor, labeled "prudent," was characterized by the intake of vegetables, fruit, cheese, and poultry. The second factor, "traditional," consisted of the intake of rice, pasta, pulses, and meat. The third factor, "snacks," was characterized as the intake of bread, butter, salami, cheese, cakes, and desserts. The fourth, "monotonous," was inversely associated with the intake of fruit, vegetables and most other food items. Factor scores for each component retained were calculated for cases and controls. After categorization of factor scores into tertiles according to the distribution of controls, odds ratios and 95% confidence intervals were calculated using unconditional multiple logistic regression. RESULTS: "Traditional" factor showed an inverse association with cancer (OR=0.51; 95% CI: 0.32; 0.81, p-value for trend 0.14), whereas "monotonous" was positively associated with the outcome (OR=1.78; 95% CI: 1.78; 2.85, p-value for trend <0.001). CONCLUSIONS: The study data suggest that the traditional Brazilian diet, consisting of rice and beans plus moderate amounts of meat, may confer protection against oral cancer, independently of any other risk factors such as alcohol intake and smoking. 相似文献

The aim of the current study was to describe the sources of variation of energy and nutrient intake and to calculate the number of repetitions of diet measurements to estimate usual intake in adolescents from S?o Paulo, Brazil. Data was collected using 24-hour dietary recalls (24hR) in 273 adolescents between 2007 and 2008. Individuals completed a repeat 24hR around two months later. The sources of variation were estimated using the random effect model. Variance ratios (within-person to between-person variance ratio) and the number of repetitions of 24hR to estimate usual intake were calculated. The principal source of variation was due to within-person variance. The contribution of day of week and month of year was less than 8%. Variations ranged from 1.15 for calcium to 7.31 for vitamin E. The number of 24hR repeats required to estimate usual intake varied according to nutrient and gender, numbering 15 for males and 8 for females. 相似文献

This profile of public dental care for children/adolescents in S?o Luís, Maranh?o State, Brazil, is based on a survey conducted through interviews, designed to identify these services and help upgrade Health Services available in this city. It describes the pediatric dental care available and the age groups attended, the qualifications of the practitioners involved, the types of treatment for primary and permanent teeth and oral health education programs run at the Municipal Healthcare Units with dental facilities, analyzed through visits and structured interviews. The findings show that dental care was available for children/adolescents (mainly between 6 and 12 years old) at 91.1% of the Healthcare Units offering daily and universal care (65.75%), as well as at those whose services are limited to certain specialties and/or specific days (34.15%). All the public Healthcare Units offered surgical treatment for permanent teeth. Fillings are used more for permanent teeth than primary teeth. Among the public Healthcare Units, 25 (55.5%) did not offer or run oral health programs. At most (75.5%) of the Units visited, dental treatment for children and adolescents is limited to basic care and directed mainly to permanent teeth. The traditional welfare model of providing care as freely demanded remains in place. 相似文献

The impact of violence on the population's health profile in large Brazilian cities is a real concern and has been incorporated into the country's public health agenda. Although violent crimes affect the entire population, they are distributed unequally in the city. In this context, analytical tools to evaluate the risk and spatial distribution of homicide are important for surveillance and prevention. The current article is a contribution in this direction. A geostatistical methodology is used to estimate and map homicide risk, and a new semivariogram estimator is presented and its application is evaluated in the city of S?o Paulo, Brazil, for the period 2002 to 2004. Homicide risk scenarios are generated using binomial cokriging and stochastic simulation procedures, allowing the demarcation of areas with greater or lesser risk that can be used to study spatial determinants of violence and improve the understanding of problems through analysis of differences across urban territories. 相似文献

OBJECTIVE: To assess asthma prevalence and potential risk factors associated. METHODS: Cross-sectional study part of the International Study of Asthma and Allergies in Childhood. A total of 561 schoolchildren aged 6-7 years from 35 public schools in the city of S?o Paulo (Southeastern Brazil) were drawn to participate in the study, in 2002. The sample consisted of 168 asthmatic and 393 non-asthmatic children who answered a questionnaire comprising 33 questions on personal, family and environmental information. The association between asthma and the risk factors studied was assessed by logistic regression analysis at a 5% statistical significance. RESULTS: Among the schoolchildren studied, 31.2% reported wheezing in the 12 months preceding the interview. The following risk factors were significantly associated with asthma: male gender (OR=2.4; 95% CI: 1.4;4.2), maternal smoking in the child's first year of life (OR=2.0; 95% CI: 1.1;3.8), eczema on characteristic body areas (OR=3.0; 95% CI: 1.2;7.6) and rhinoconjunctivitis (OR=2.4; 95% CI: 1.2;4.8). CONCLUSIONS: Asthma prevalence in the study area was high and the risk factors identified were male gender, rhinoconjunctivitis in last year, maternal smoking in the child's first year of life and eczema on characteristic body areas. 相似文献

Performance assessment in health services is essential. The comparison of performance indicators requires the use of risk adjustment strategies. The objective of this paper was to assess variations in clinical performance, measured by hospital mortality and length of stay, between private and public hospitals, while taking into account the hospital case mix. This study is located in the Ribeir?o Preto region in S?o Paulo State, Brazil. From 1996 to 1998, 32,906 patients admitted with cardiovascular and respiratory diagnoses were studied. Variables used for risk adjustment of performance indicators were: sex, age, principal diagnosis, and severity measures based on co-morbidity. Clinical performance in public hospitals as measured by adjusted hospital mortality (OR = 0.41) was better than in private hospitals. Public and private hospitals were not statistically different concerning patients' length of stay. Although some conceptual and methodological problems persist, hospital mortality and other adjusted performance indicators should be considered as useful tools to identify health services' performance problems. 相似文献

OBJECTIVE: To assess risk factors for low height and students and working adolescents in cities of State of S?o Paulo, Brazil. METHODS: A stratified sample, consisting of 50.0% of students from 5th grade to last year of high school, of State of S?o Paulo, Brazil, in 1999, was drawn from two largest schools of two different cities (urban and rural). A total of 756 individuals were studied. The height/age indicator, according to the 1977-NCHS (National Center for Health Statistics) standards, defined malnutrition. Height/age distribution and multivariate analyses were carried out using the stepwise method and low-height as the dependent variable. RESULTS: Of the adolescents, 12.7% (96) fell below percentile 5; 24.4% (184) between percentiles 5 - 15; and 47.1% (356) between percentiles 15 - 50. Low height was associated with age: taking age-group 10-13 as reference, low-height was twice as likely in students aged 14-17 years (OR adj.=2.49). For those aged 17-19 years, low height was three times as likely (OR adj.=3.37). Being unemployed increases the risk for low-height (OR adj.=2.86) when compared to working adolescents. Also, low height is higher (OR adj.=1.81) among part-time workers. CONCLUSION: Economical determinants contribute to the risks for chronic malnutrition among students, since these adolescents rely on work to live on. It is worth emphasizing that underage labor legislation should be enforced in conjunction with compensation public programs. 相似文献

Redemocratization in the 1970s brought about changes in the public health system in Brazil. The Unified National Health System (SUS) was implemented in 1988, based on local and regional administrative systems. This was an important step that resulted in greater local control and the introduction of new technologies. This study focuses on the local health system in Campinas, a relatively affluent and technologically advanced region some 100km from the city of S?o Paulo in Southeast Brazil. Qualitative and quantitative methods were used to evaluate the work of 233 nurses in the local health system. The first nurse was hired in 1977, and now there are 53 nurses working in specific areas: 10 in the central health administration, 36 in district administrations, and the rest in local services. Nursing services are organized in six main areas: administration, coordination of human resources, education, information technology, health surveillance, and health administration. Nursing intervention may be found in various areas, but it generally focuses on medical consultations, and there is little emphasis on collective activities and health promotion. Local health objectives can only be achieved by creating new practices that promote collective health. 相似文献

Wheezing conditions in early childhood: prevalence and risk factors in the city of São Paulo, Brazil
Benício MH Ferreira MU Cardoso MR Konno SC Monteiro CA 《Bulletin of the World Health Organization》2004,82(7):516-522
OBJECTIVE: To investigate the prevalence and risk factors for wheezing disorders in early childhood in São Paulo, Brazil, the largest metropolitan area of South America. METHODS: A population-based cross-sectional survey of 1132 children aged 6-59 months was carried out between 1995 and 1996 to obtain information on recent wheezing and on independent variables such as demographic, socioeconomic, environmental, maternal and nutritional variables and immunization status. Intestinal parasitic infections were diagnosed using standard techniques. Multiple unconditional logistic regression was used to describe associations between outcome and independent variables. FINDINGS: The prevalence of recent wheezing (one or more reported episodes in the past 12 months) was 12.5%; 93% of children with wheezing were also reported to have a medical diagnosis of asthma. Recent wheezing was associated with low per capita income, poor quality of housing, day-care attendance, low birth weight and infection with intestinal helminths. CONCLUSION: Wheezing in early childhood in São Paulo, although more common than in most developing countries, remains less prevalent than in urban areas of industrialized countries. Low income and conditions associated with poverty (poor housing, low birth weight and parasitic infections) are some of the main risk factors for wheezing disorders among young children in this city. 相似文献
