Entre o medo da contaminação pelo HIV e as representações simbólicas da AIDS: o espectro do desespero contemporâneo
Este estudo pretende colaborar para uma melhor compreensão dos sentimentos provocados no ser humano vivendo em plena era da AIDS. A falta de informação e, por consequência, o desconhecimento sobre a AIDS, sua dinâmica de transmissão e as medidas preventivas adequadas, transformam a convivência com esta síndrome num fator estressante para muitas pessoas, gerando sentimentos de medo e suscitando a correlação com diferentes representações simbólicas ligadas à contaminação pelo HIV. Vários autores formularam modelos teóricos para explicar esta correlação. Neste trabalho procura-se verificar os sentimentos emergentes e a respectiva vinculação aos significados simbólicos da doença sob o prisma destas teorias. Foram entrevistadas 31 pessoas, sendo 10 estudantes de diferentes cursos superiores da Universidade de São Paulo e 21 detentos do Sistema Penitenciário do Estado de São Paulo. Os resultados obtidos mostraram que, apesar dos grupos apresentarem características diferentes entre si, ambos atribuiram à AIDS significados simbólicos ligados ao medo da contaminação pelo HIVLack of knowledge and mis informations on HIV/AIDS are predictors of emotional responses as fear of contagion, homophobia, avoidance and excessive precautions. Fear of contagion is an affective stress response to the neurocognitive activity that leads to a perceived threat of AIDS in connection with the symbolic meanings os illness. Focused interviews were conducted with an opportunistic sample of 31 young people to know the affective responses and behaviors after blood screening for HIV antibody testing. The findings confirm the relationship of symbolic representation of illness as mystery, death, punishment and sexuality to fear of contagion and mitic conception of AIDS

Cognitive-behavioural health-promotion intervention increases fruit and vegetable consumption and physical activity among South African adolescents: a cluster-randomised controlled trial
Rates of chronic diseases are high among Black South Africans but few studies have tested cognitive-behavioural health-promotion interventions to reduce this problem. We tested the efficacy of such an intervention among adolescents in a cluster-randomised controlled trial. We randomly selected 9 of 17 matched pairs of schools and randomised one school in each pair to the cognitive-behavioural health-promotion intervention designed to encourage health-related behaviours and the other to a human Immunodeficiency virus (HIV)/sexually transmitted disease (STD) risk-reduction intervention that served as the control. Interventions were based on social cognitive theory, the theory of planned behaviour and qualitative data from the target population. Data collectors, blind to participants' intervention, administered confidential assessments at baseline and 3, 6 and 12 months post-intervention. Primary outcomes were fruit and vegetable consumption and physical activity. Participants were 1057 grade 6 learners (mean age=12.4 years), with 96.7% retained at 12-month follow-up. Generalised estimating equations revealed that averaged over
the follow-ups, a greater percentage of health-promotion intervention participants than HIV/STD control participants met 5-a-Day fruit and vegetable and physical activity guidelines. The intervention also increased health-promotion knowledge, attitude and intention, but did not decrease substance use or substance-use attitude and intention. The findings suggest that theory based and contextually appropriate interventions may increase health behaviours among young adolescents in sub-Saharan Africa.

School-based randomized controlled trial of an HIV/STD risk-reduction intervention for South African adolescents
The objective of this study was to test the efficacy of a school-based human HIV/STD risk reduction intervention for adolescents in South Africa. A cluster-randomized controlled design with assessments of self-reported sexual behaviour was collected before intervention and 3, 6 and 12 months after invention.
HIV/STI risk-reduction intervention efficacy with South African adolescents over 54 months
Little research has tested HIV/sexually transmitted infection (STI) risk-reduction interventions' effects on early adolescents as they age into middle and late adolescence. This study tested whether intervention-induced reductions in unprotected intercourse during a 12-month period endured over a 54-month period and whether the intervention reduced the prevalence of STIs, which increase risk for HIV. Grade 6 learners (mean age = 12.4 years) participated in a 12-month trial in Eastern Cape Province, South Africa, in which 9 matched pairs of schools were randomly selected and within pairs randomized to a theory-based HIV/STI risk-reduction intervention or an attention-control intervention. They completed 42- and 54-month post-intervention measures of unprotected intercourse (the primary outcome), other sexual behaviors, theoretical constructs, and, at 42- and 54-month follow-up only, biologically confirmed curable STIs (chlamydial infection, gonorrhea, and trichomoniasis) and herpes simplex virus 2. Results: The HIV/STI risk-reduction intervention reduced unprotected intercourse averaged over the entire follow-up period, an effect not significantly reduced at 42- and 54-month follow-up compared with 3-, 6-, and 12-month follow-ups. The intervention caused positive changes on theoretical constructs averaged over the 5 follow-ups, although most effects weakened at long-term follow-up. Although the intervention's main effect on STIs was nonsignificant, an Intervention Condition X Time interaction revealed that it significantly reduced curable STIs at 42-month follow-up in adolescents who reported sexual experience. These results suggest that theory-based behavioral interventions with early adolescents can have long-lived effects in the context of a generalized severe HIV epidemic.
