ABSTRACT OBJETIVO: Comparar o conhecimento sobre métodos anticoncepcionais e identificar os fatores associados ao conhecimento adequado dos adolescentes de escolas públicas e privadas. MÉTODOS: Realizou-se estudo transversal, do qual participaram 1.594 adolescentes entre 12 e 19 anos, de 13 escolas públicas e cinco privadas do Município de São Paulo entre junho e dezembro de 2003. As escolas foram selecionadas aleatoriamente e os alunos responderam um questionário sobre características sociodemográficas, reprodutivas e métodos anticoncepcionais. As razões de prevalência foram calculadas com intervalo de confiança de 95% para cada questão sobre conhecimento de métodos e o tipo de escola. Atribuiu-se meio ponto para cada questão correta sobre conhecimento de anticoncepcionais, o ponto de corte foi 50% de acerto. Os testes estatísticos utilizados foram o qui-quadrado, o Wilcoxon-Gehan e a regressão múltipla de Poisson. RESULTADOS: Dentre os adolescentes, 61% eram do sexo feminino nos dois grupos de escolas. Predominou nível socioeconômico baixo nas escolas públicas e alto nas privadas (p<0,001). Cerca de 18,6% dos adolescentes nas escolas privadas e 28,6% nas públicas tinham atividade sexual (p<0,002). Quanto ao conhecimento, 25,7% dos adolescentes das escolas públicas e 40,8% das privadas apresentaram escore superior ou igual a cinco. Os fatores associados ao maior conhecimento foram ser do sexo feminino, estudar em escola privada, estar no ensino médio, ter nível socioeconômico alto, ter relação sexual e ter maior idade. CONCLUSÕES: O nível de conhecimento adequado sobre métodos anticoncepcionais foi baixo para os adolescentes de ambos os tipos de escolas. Os resultados revelam que, assim como os mais desfavorecidos, os adolescentes de maior nível socioeconômico necessitam de informações adequadas sobre planejamento familiar, visando a melhorar esse conhecimento para mudança seu comportamento.

    ABSTRACT: The literature shows that although young people have sufficient knowledge about contraceptive methods, the frequency of their use is low. This study investigated the use of condoms and possible controlling variables of this behavior in students aged between 13 and 18 years old. A structured questionnaire was used, the results of which suggested that: (1) adolescents demonstrated that they followed rules that encourage the behavior of not using condoms, (2) parents or guardians do not control this behavior punitively, (3) health services provide little reinforcement in clarifying doubts about sexuality and obtaining condoms. The influence of individual history and cultural practices on the results was analyzed.

    ABSTRACT: The purpose of this study was to assess the feasibility of implementing an outpatient model of a newborn hearing screening program with a particular focus on determining how compliance with the follow-up appointment related to specific socio-economic and demographic factors associated with the mother. Mothers who delivered their babies in public hospitals in Recife, northeast Brazil, were invited to participate in a two-step program. In Step 1 they were interviewed with regard to specific socio-economic and demographic factors, and then scheduled for a hearing screening test for their baby 1 month after discharge. In Step 2, the baby's hearing was screened using transient otoacoustic emissions. A total of 1035 mothers consented to participate in Step 1, but only 149 returned to participate in Step 2 (14.3%). Analysis of the socio-economic and demographic factors indicated that mothers who did not comply with the scheduled newborn hearing screening (NHS) test generally had less than a high school education and came from primarily lower income families who lived in rural areas outside of Recife. The results of this study highlight some socio-economic and demographic factors of the population of northeast Brazil that contribute to a low compliance rate for an outpatient model of a newborn hearing screening program. Possible solutions to the low compliance rate are considered.

    ABSTRACT: Health-related quality of life (HRQoL) assessment, encompassing the adolescents' perceptions of their mental, physical, and social health and well-being is increasingly considered an important outcome to be used to identify population health needs and to provide targeted medical care. Although validated instruments are essential for accurately assessing HRQoL outcomes, there are few cross-culturally adapted tools for use in Brazil, and none designed exclusively for use among adolescents. The Vécu et Santé Perçue de l'Adolescent (VSP-A) is a generic, multidimensional self-reported instrument originally developed and validated in France that evaluates HRQoL of ill and healthy adolescents. To cross-culturally adapt and validate the Brazilian-Portuguese version of the VSP-A, a generic HRQoL measure for adolescents originally developed in France. The VSP-A was translated following a well-validated forward-backward process leading to the Brazilian version. The psychometric evaluation was conducted in a sample of 446 adolescents (14-18 years) attending 2 public high schools of São Gonçalo City. The adolescents self-reported the Brazilian VSP-A, the validated Psychosomatic Symptom Checklist and socio-demographic information. A retest evaluation was carried out on a sub-sample (n = 195) at a two-week interval. The internal construct validity was assessed through confirmatory factor analysis (CFA), multi-trait scaling analyses, Rasch analysis evaluating unidimensionality of each scale and Cronbach's alpha coefficients. The reproducibility was evaluated by intra-class correlation coefficients (ICC). Zumbo's ordinal logistic regression analysis was used to detect differential item functioning (DIF) between the Brazilian and the French items. External construct validity was investigated testing expected differences between groups using one-way analysis of variance (ANOVA), Mann-Whitney tests and the univariate general regression linear model. CFA showed an acceptable fit (RMSEA=0.05; CFI=0.93); 94% of scaling success was found for item-internal consistency and 98% for item discriminant validity. The items showed good fit to the Rasch model except 3 items with an INFIT at the upper threshold. Cronbach's Alpha ranged from 0.60 to 0.85. Test-retest reliability was moderate to good (ICC=0.55-0.82). DIF was evidenced in 4 out of 36 items. Expected patterns of differences were confirmed with significantly lower physical, psychological well being and vitality reported by symptomatic adolescents. Although DIF in few items and responsiveness must be further explored, the Brazilian version of VSP-A demonstrated an acceptable validity and reliability in adolescents attending school and might serve as a starting point for more specific clinical investigations.
