Assessment of lunch served in the Workers' Food Program, Brazil

OBJECTIVE: In the light of the Workers' Food Program (WFP) growth and its recent review of nutritional parameters regulations, the study aimed at evaluating food intake in WFP through dietary assessment of lunch served in the program and workers' nutritional status. METHODS: A cross-sectional study was carried out in a representative sample of workers in Brasilia, Federal District, Brazil. A total of 1,044 subjects who had lunch at 52 food and nutrition units were evaluated. Social-economic and demographic data were collected as well as anthropometric measures for calculating the Body Mass Index. Food intake was assessed by dish weight and direct observation of dish composition. RESULTS: Of all subjects, 43% had excess weight, 33.7% were overweight and 9.3% were obese. Males were most affected. Median lunch energy intake was 515 kcal in women and 736 kcal in men. Median dietary fiber intake was 6.0 g among women and 8.3 g among men, and median cholesterol intake was over 90 mg among subjects with excess weight. CONCLUSIONS: The results indicate that the study population who is often seen as healthy is at nutritional risk. Workers in WFP should be targeted for health promotion strategies using especially nutritionists' skills as educators.     

Alcohol and alcoholism among Brazilian adolescent public-school students

OBJECTIVE: To estimate the prevalence of alcohol consumption and alcoholism among working and non-working adolescents. METHODS: Cross-sectional study with a systematic, stratified sample 993 working adolescents and 1,725 non-working adolescents. The study included students enrolled in 1998 in the state public network schools of a city in Center-Western Brazil. An anonymous, self-administered questionnaire was completed by subjects in the classroom. Univariate and bivariate analyses and logistic regression were used. RESULTS: We found prevalences of 71.3% for alcohol consumption and 13.4% for alcoholism in the total sample, and higher prevalences among working students (81.0% and 14.9%) than among non-workers (65.8% and 12.6%). In addition to the association between alcohol use and work, we found both differences and similarities between the two groups. Alcoholism is not associated with work but is associated with male sex (OR=1.61; 95% CI: 1.18-2.19) and family history of alcohol use among both non-workers (OR=2.19; 95% CI: 1.60-2.99) and workers (OR=2.10; 95% CI: 1.42-3.12). CONCLUSIONS: The results of the present study indicate a high prevalence of alcohol consumption and alcoholism, which is higher among working adolescents. Sociodemographic, family, and work-related factors must be considered when attempting to implement educational measures aimed at changing alcohol-related behaviors in this population.     

Maternal posture and its influence on birthweight

OBJECTIVE: To analyze the relationship between maternal posture/physical activity and inadequate birthweight. METHODS: Prospective cohort study involving 152 pregnant women from a public low-risk antenatal care facility. Three interviews evaluating the frequency of physical activity were administered to each pregnant woman during gestation. Birthweight (inadequate when <3,000 g and adequate when > or =3,000 g) was the dependent variable and the frequency of physical activity the independent variable. Statistical analysis was performed using logistic univariate analysis and multiple regression controlling for schooling, smoking, living with spouse, and baseline nutritional status. RESULTS: The practice of walking for at least 50 minutes during the first period of pregnancy was identified as a protective factor against inadequate birthweight (adjusted OR=0.44; 95% CI: 0.20-0.98). Standing for 2.5 hours or longer during the second semester of pregnancy was associated with increased risk (adjusted OR=3.23; 95% CI: 1.30-7.99). Dose-response relationships were identified for washing clothing by hand and cooking (p-value for linear trend <0.01 and 0.05, respectively). After confounder control, only washing clothing during the second trimester of gestation remained statistically significant. CONCLUSIONS: Our results show the importance of medical orientation regarding posture and physical activity during antenatal care, aiming at the reduction of inadequate birthweight.     

The services for women victims of sexual violence: a qualitative study

OBJECTIVE: To assess public services attending female victims of sexual violence in the city of Sao Paulo. METHODS: This is a qualitative study conducted in two public services attending female victims of sexual violence. Interviews with 42 women were conducted, 13 of whom had sought these services for assistance and 29 were professionals working in these services. Evaluation of the services was based on the categories: reception, access, resolvability and sanitary responsibility. RESULTS: The analysis of the interviews per category has shown that there was reception in both services, problems with respect to access due to the lack of information concerning these services, and quality resolvability with a multi-professional team. As to the sanitary responsibility, it is present in these specialized services but is deficient in the emergency services and basic health care units. Many women are unaware of the rights they are entitled to with respect to specialized services. Frequently their late arrival compromises the efficacy of care. There are deficiencies both in terms of reference and counter reference. CONCLUSIONS: The results ratify the importance of these services and the need for their decentralized expansion. Health courses should introduce the theme of sexual violence at the undergraduate level.     

Risk factors for cutaneous leishmaniasis transmission in children aged 0 to 5 years in an endemic area of Leishmania (Viannia) braziliensis

With the purpose of identifying risk factors for cutaneous leishmaniasis transmission in children from 0 to 5 years, a matched case-control study was carried out in Corte de Pedra, Bahia, Brazil, an endemic area of Leishmania (Viannia) braziliensis. Children with a positive leishmanin skin test and one or more active lesions or scars consistent with cutaneous leishmaniasis were defined as cases. Forty cases and 71 controls were selected and matched by age and place of residence. The presence of a family member with a history of cutaneous leishmaniasis in the year prior to the appearance of the disease in the child was found to be an important risk factor (MORMH = 17.75; 95%CI: 4.08-77.25). No evidence of association between the disease and other risk factors was found, such as child's habits inside or outside the house, domiciliary or peridomiciliary characteristics, or presence of vectors or probable reservoir animals. These findings support the hypothesis that humans serve as both the reservoir and source of infection for this age group.     

A monitoring system for work-related accidents in Piracicaba, São Paulo, Brazil

The authors report on the development of a work accident monitoring system in Piracicaba, S?o Paulo State, Brazil, with the following characteristics: information feeding the system is obtained in real time directly from accident treatment centers; the system has universal monitoring, covering all work-related accidents in Piracicaba, regardless of the nature of the worker's employment conditions, place of work, or place of residence; health surveillance and promotion of health initiatives are triggered by identification of sentinel events; spatial distribution analysis of work-related accidents is a basic tool in designing accident awareness strategies and accident prevention policies. The system was implemented in November 2003 and by October 2004 had identified 5,320 work-related accidents, or a 3.8% annual proportional incidence of work-related accidents in the municipal area. We illustrate spatial analysis of registered work-related accidents and present a detailed investigation of one example of a serious accident.     

Analysis of nonverbal communication of ostomy patients due to bowel cancer in a focus group

This study aimed to analyze the frequency of efficient and inefficient behavior in members of a group of ostomy patients due to bowel cancer. An exploratory and observational field study took place at a public service hospital in S?o Paulo, Brazil. The population consisted of 5 persons who joined in a group. After approval by the institutional Ethics Committee, 5 meetings were held in October and November 2001, guided by the following themes "me before getting ill", "me ill and the treatment", "me recovering with an ostomy", "me and daily life", "me in this group". Data were collected through videotaping of the meetings and field diary records, and were subject to quantitative analysis by means of tables and graphs, on the basis of an established model. The preponderance of rigidity and competitiveness in the intragroup relationships was explicit and determined stagnation and stereotyped attitudes in interaction.     

The professional self and hetero image among public health nurses: a study of social representations

The object of this study is the professional image constructed by public health nurses and the objective is to describe and analyze the professional images present in the representations of nurses who deliver direct care to this clientele. The theoretical-methodological reference framework adopted was Social Representations Theory. A qualitative study was developed in Petrópolis-Rio de Janeiro/Brazil, through in-depth interviews with 30 nurses. Alceste 4.5 software was used for the lexical analysis. The results reveal the existence of a professional self-image with three groups of meanings: being a reference for the team, the non-specific image and the image of plaster; and a professional hetero-image with four groups of meanings: administrator, invisible, positive image and superposition. The study of the professional image reflects the construction of the nurse's identity in itself and emphasizes Social Representations Theory as a useful tool for nursing research development.     

Conventional and sutureless techniques for management of the pulmonary veins: Evolution of indications from postrepair pulmonary vein stenosis to primary pulmonary vein anomalies

OBJECTIVE: We have previously reported a limited but favorable experience with a novel sutureless technique for surgical management of postoperative pulmonary vein stenosis occurring after repair of total anomalous pulmonary venous drainage. Because this technique requires integrity of the retrocardiac space for hemostasis, extension of the technique to the primary repair of pulmonary vein anomalies requires evaluation. This analysis reviews our experience with the sutureless technique in patients with postrepair pulmonary vein stenosis, as well as our extension of the technique into primary repair of pulmonary vein anomalies. METHODS: Retrospective univariable-multivariable analysis of all pulmonary vein stenosis procedures and sutureless pulmonary vein procedures over a 20-year period was performed. Cox proportional hazards modeling was used to identify variables associated with freedom from reoperation or death. RESULTS: Sixty patients underwent 73 procedures, with pulmonary vein stenosis present in 65 procedures. The sutureless technique was used in 40 procedures. Freedom from reoperation or death at 5 years after the initial procedure was 49%. Unadjusted freedom from reoperation or death was greater with the sutureless technique for patients with postrepair pulmonary vein stenosis ( P = .04). By using multivariable analysis, a higher pulmonary vein stenosis score was associated with greater risk of reoperation or death. After adjustment, the sutureless repair was associated with a nonsignificant trend toward greater freedom from reoperation or death ( P = .12). Despite the absence of retrocardiac adhesions, operative mortality was not increased with the sutureless technique ( P = .64). Techniques to control bleeding (intrapleural hilar reapproximation) and improve exposure (inferior vena cava division) were identified. CONCLUSION: The sutureless technique for postrepair pulmonary vein stenosis is associated with encouraging midterm results. Extension of the indications for the technique to primary repair appears safe with the development of simple intraoperative maneuvers.
