Orientação sexual e educação física: sobre a prática pedagógica do professor na escola

Na escola a sexualidade é tópico polêmico, em face da multipicidade de visões, crenças e valores de seus diversos atores. O objetivo desta pesquisa foi investigar como os professores de Educação Física compreendem o papel deste componente curricular no trabalho de orientação sexual nos anos finais do Ensino Fundamental. A metodologia utilizada foi de natureza qualitativa, e a entrevista semiestruturada foi a estratégia escolhida para a coleta dos dados descritivos presentes no discurso dos professores. Os resultados indicaram que a Educação Física congrega elementos importantes ligados à sexualidade, sobretudo ao trabalhar diretamente "com o corpo" e "no corpo", por meio de seus conteúdos. A esse respeito, sugere-se a construção de um currículo escolar no qual o corpo apareça como elemento central na articulação de projetos interdisciplinares, e ressalta-se a necessidade de os professores conhecerem os mecanismos corporais que resultam em bloqueios e dificuldades emocionais ligados à sexualidade.

Aircraft noise, air pollution, and mortality from myocardial infarction

Objective: Myocardial infarction has been associated with both transportation noise and air pollution. We examined residential exposure to aircraft noise and mortality from myocardial infarction, taking air pollution into account. Methods: We analyzed the Swiss National Cohort, which includes geocoded information on residence. Exposure to aircraft noise and air pollution was determined based on geospatial noise and air-pollution (PM10) models and distance to major roads. We used Cox proportional hazard models, with age as the timescale. We compared the risk of death across categories of A-weighted sound pressure levels (dB(A)) and by duration of living in exposed corridors, adjusting for PM10 levels, distance to major roads, sex, education, and socioeconomic position of the municipality. Results: We analyzed 4.6 million persons older than 30 years who were followed from near the end of 2000 through December 2005, including 15,532 deaths from myocardial infarction (ICD-10 codes I 21, I 22). Mortality increased with increasing level and duration of aircraft noise. The adjusted hazard ratio comparing ≥60 dB(A) with <45 dB(A) was 1.3 (95% confidence interval = 0.96-1.7) overall, and 1.5 (1.0-2.2) in persons who had lived at the same place for at least 15 years. None of the other endpoints (mortality from all causes, all circulatory disease, cerebrovascular disease, stroke, and lung cancer) was associated with aircraft noise. Conclusion: Aircraft noise was associated with mortality from myocardial infarction, with a dose-response relationship for level and duration of exposure. The association does not appear to be explained by exposure to particulate matter air pollution, education, or socioeconomic status of the municipality.

Study Abroad Increases Risk for Sexual Assault in Female Undergraduates: A Preliminary Report

Since 2007, more than 250,000 American students have studied abroad annually for a semester or more. While there are obvious benefits associated with study abroad programs, personal risks (including interpersonal victimization such as sexual and physical assault) occurring during the experience have been anecdotally reported but not systematically assessed. This study is the first to investigate the possibility of increased risk for sexual assault in female undergraduates while abroad. Two hundred eighteen female undergraduates completed a modified version of the Sexual Experiences Survey (SES: Koss et al., 2007) about their sexual experiences abroad and on campus. Findings indicate increased risk for sexual assault while abroad relative to on-campus rates, particularly in non-English speaking countries. Study abroad programs should consider educating students about increased risk and develop response protocols when sexual assaults happen while abroad.

What can be gained from comprehensive disaggregate surveillance? The Avon Surveillance System for Sexually Transmitted Infections

OBJECTIVE: To describe a new disaggregate surveillance system covering key diagnosed sexually transmitted infections in a UK locality. METHODS: The Avon System for Surveillance of Sexually Transmitted Infections (ASSIST) collects computerised person- and episode-based information about laboratory-diagnosed sexually transmitted infections from genitourinary medicine (GUM) clinics, the Avon Brook Clinic, and the Health Protection Agency and trust laboratories in primary care trusts in Avon. The features of the system are illustrated here, by describing chlamydia-testing patterns according to the source of test, age and sex, and by mapping the distribution of chlamydia across Bristol, UK. RESULTS: Between 2000 and 2004, there were 821,685 records of tests for sexually transmitted infections, with 23,542 positive results. The proportion of tests and positive results for chlamydia and gonorrhoea sent from general practice increased over time. Most chlamydia tests in both GUM and non-specialist settings were performed on women aged >25 years, but positivity rates were highest in women aged <25 years. The positivity rate remained stable between 2000 and 2004. Including data from all diagnostic settings, chlamydia rates were about twice as high as those estimated only from genitourinary clinic cases. CONCLUSIONS: The ASSIST model could be a promising new tool for planning and measuring sexual health services in England if it can become sustainable and provide more timely data using fewer resources. Collecting denominator data and including infections diagnosed in primary care are essential for meaningful surveillance.

Randomized comparisons among health informatics students identify hypertutorial features as improving web-based instruction.

Hypertutorials optimize five features - presentation, learner control, practice, feedback, and elaborative learning resources. Previous research showed graduate students significantly and overwhelmingly preferred Web-based hypertutorials to conventional "Book-on-the-Web" statistics or research design lessons. The current report shows that the source of hypertutorials' superiority in student evaluations of instruction lies in their hypertutorial features. Randomized comparisons between the two methodologies were conducted in two successive iterations of a graduate level health informatics research design and evaluation course. The two versions contained the same text and graphics, but differed in the presence or absence of hypertutorial features: Elaborative learning resources, practice, feedback, and amount of learner control. Students gave high evaluations to both Web-based methodologies, but consistently rated the hypertutorial lessons as superior. Significant differences localized in the hypertutorial subscale that measured student responses to hypertutorial features.

Commentary on "A Tale of Two States"

While both California and Texas have experienced declines in teen birth rates over the past three decades, declines in California have been larger, particularly among Hispanic teens. Differences in state policies may have shaped this disparity, as suggested by Tortolero and her colleagues in their article “A Tale of Two States: What We Learn from California and Texas”. Fundamental differences exist between Texas and California in their approaches to sex education, access to family planning services for teens, and public-private partnerships. However, methodological challenges are present when drawing state comparisons, including the limitations of available public health data and the difficulty of disaggregating state characteristics from state policies. Based on their comparison of state data and policies, Tortolero and her colleagues issue sensible recommendations for reducing the teen birth rate in Texas. History suggests that state policies are most effective when political commitment is linked to scientifically effective approaches. Based on our understanding of the scientific literature, the most effective strategies for reducing rates of teen childbearing in Texas would be providing comprehensive school sexuality education and improving teen access to contraceptive services.

Sexually transmitted infections in HIV-infected people in Switzerland: cross-sectional study.

Sexually transmitted infections (STI) in HIV-infected people are of increasing concern. We estimated STI prevalence and sexual healthcare seeking behaviour in 224 sexually active HIV-infected people, including men who have sex with men (MSM, n = 112), heterosexual men (n = 65) and women (n = 47). Laboratory-diagnosed bacterial STI were more common in MSM (Chlamydia trachomatis 10.7%; 95% CI 6.2, 18.0%, lymphogranuloma venereum 0.9%; 95% CI 0.1, 6.2%, Neisseria gonorrhoeae 2.7%; 95% CI 0.9, 8.0%, syphilis seroconversion 5.4%; 95% CI 2.0, 11.3%) than heterosexual men (gonorrhoea 1.5%; 95% CI 0.2, 10.3%) or women (no acute infections). Combined rates of laboratory-diagnosed and self-reported bacterial STI in the year before the study were: MSM (27.7%; 95% CI 21.1, 36.7%); heterosexual men (1.5%; 95% CI 0.2, 10.3%); and women (6.4%; 95% CI 2.1, 21.0%). Antibodies to hepatitis C virus were least common in MSM. Antibodies to herpes simplex type 2 virus were least common in heterosexual men. Most MSM, but not heterosexual men or women, agreed that STI testing should be offered every year. In this study, combined rates of bacterial STI in MSM were high; a regular assessment of sexual health would allow those at risk of STI to be offered testing, treatment and partner management.

The population health performance of medical students at two medical schools

Public Health and medicine are complimentary disciplines dedicated to the health and well-being of humankind. Worldwide, medical school accreditation bodies require the inclusion of population health in medical education. In 2003, the Institutes of Medicine (IOM) recommended that all medical students receive basic public health training in population-based prevention. The purpose of this study was to (1) examine the public health clinical performance of third-year medical students at two independent medical schools, (2) compare the public health clinical practice performance of the schools, and (3) identify underlying predictors of high and low public health clinical performance at one of the medical schools. ^ This study is unique in its analysis and report of observed medical student public health clinical practices. The cohort consisted of 751 third-year medical students who completed a required clinical performance exam using trained standardized patients. Medical student performance scores on 24 consensus public health items derived from nine patient cases were analyzed.^ The analysis showed nearly identical results for both medical schools at the 60%, 65%, and 70% pass rate. Students performed poorly on items associated with prevention, behavioral science, and surveillance. Factors associated with high student performance included being from an underrepresented minority, matching to a primary care residency, and high class ranking. A review of medical school curriculum at both schools revealed a lack of training in four public health domains. Nationally, 32% of medical students reported inadequate training in public health in the year 2006.^ These findings suggest more dedicated teaching time for public health domains is needed at the medical schools represented in this study. Finally, more research is needed to assess attainment of public health knowledge and skills for medical students nationwide if we are to meet the recommendations of the IOM. ^

Comparing barriers and predictors for colorectal cancer screening between African Americans and Whites

Colorectal cancer (CRC) has been one of the leading causes of cancer death in the United States. Although incidence and mortality rates of colorectal cancer in the United States have decreased in recent years, the disparity in CRC incidence and mortality between African Americans and Whites remain. Disparity in CRC screening rates is believed to be one of the causes that contribute to the disparity in CRC incidence and mortality between these two races. Finding the differences in CRC screening barriers and predictors between these two groups can help us to design more effective intervention programs to improve CRC screening rates for African Americans. However, most of the previous studies have investigated different types of CRC screening barriers for African Americans and/or Whites, but no studies have compared the same CRC screening barriers between African Americans and Whites. The purpose of this study is to describe and compare the same CRC screening barriers between these two races. Using chi-square analysis, significant differences between African Americans and Whites were found for marital status, income and education. Compared to Whites, African Americans were less aware of CRC screening procedures and lacked CRC knowledge. Significant differences were found between African Americans and Whites in the awareness of sigmoidoscopy, colonoscopy and barium enema. After adjusting for sex, education, marital status, and household income, six out of thirteen CRC screening barriers and two out of nine CRC screening predictors remained to be statistically significantly different between African Americans and Whites. The results of this study indicated that different CRC screening barriers and predictors had different impact on African Americans, and African Americans had more CRC barriers to overcome than Whites.^

"Teens talk healthy weight": A video technology project

Purpose. The purpose of this study was to investigate the impact of a motivational weight management DVD on knowledge of obesity related diseases, readiness, motivation, and self-efficacy to lose weight, connectedness to their care provider, and patients return to clinic. Design. A randomized control trial was conducted in which 40 overweight/obese adolescents and their parents/caregivers were randomly assigned to standard care alone or standard care plus DVD. Subjects completed a set of pre- and post-questionnaire measures. A group of 22 patients was also formed as a historical control group in order to account for the potential effect of extra attention given to subjects prospectively enrolled. Methods. The adolescents and their parent/caregiver were placed into a patient room. Consent was obtained and a set of written pre-questionnaires were given to both the parent and the adolescent. Standard care was provided to all patients by the Registered Dietitian and physician; the DVD was shown in addition to standard care among the intervention group. A set of post-questionnaires were given and compensation was provided. Analysis. Groups were compared to determine equivalence at baseline. Analysis of covariance was used to evaluate changes over time, while controlling for pre-test scores and race/ethnicity. Results. Parents who viewed the DVD experienced greater changes in correct knowledge as compared to parents who did not view the DVD. Conclusion. Our study found only one substantial benefit of the DVD beyond standard clinical practices. This is an important area for change as it increased awareness of obesity as a serious disease and has future clinical implications.^

THE EFFECT OF PERSON-ENVIRONMENT INTERACTION ON ANXIETY, DEPRESSION, AND SUBJECTIVE DISTRESS OF OPTOMETRY STUDENTS

The purpose of this study was to investigate whether an incongruence between personality characteristics of individuals and concomitant charcteristics of health professional training environments on salient dimensions contributes to aspects of mental health. The dimensions examined were practical-theoretical orientation and the degree of structure-unstructure. They were selected for study as they are particularly important attributes of students and of learning environments. It was proposed that when the demand of the environment is disparate from the proclivities of the individual, strain arises. This strain was hypothesized to contribute to anxiety, depression, and subjective distress.^ Select subscales on the Omnibus Personality Inventory (OPI) were the operationalized measures for the personality component of the dimensions studied. An environmental index was developed to assess students' perceptions of the learning environment on these same dimensions. The Beck Depression Inventory, State-Trait Anxiety Inventory and General Well-Being schedule measured the outcome variables.^ A congruence model was employed to determine person-environment (P-E) interaction. Scores on the scales of the OPI and the environmental index were divided into high, medium, and low based on the range of scores. Congruence was defined as a match between the level of personality need and the complementary level of the perception of the environment. Alternatively, incongruence was defined as a mismatch between the person and the environment. The consistent category was compared to the inconsistent categories by an analysis of variance procedure. Furthermore, analyses of covariance were conducted with perceived supportiveness of the learning environment and life events external to the learning environment as the covariates. These factors were considered critical influences affecting the outcome measures.^ One hundred and eighty-five students (49% of the population) at the College of Optometry at the University of Houston participated in the study. Students in all four years of the program were equally represented in the study. However, the sample differed from the total population on representation by sex, marital status, and undergraduate major.^ The results of the study did not support the hypotheses. Further, after having adjusted for perceived supportiveness and life events external to the learning environment, there were no statistically significant differences between the congruent category and incongruent categories. Means indicated than the study sample experienced significantly lower depression and subjective distress than the normative samples.^ Results are interpreted in light of their utility for future study design in the investigation of the effects of P-E interaction. Emphasized is the question of the feasibility of testing a P-E interaction model with extant groups. Recommendations for subsequent research are proposed in light of the exploratory nature of the methodology. ^
