Abstract
To address global questions regarding the timing of HIV-prevention efforts targeting youth and the possible additional benefits of parental participation, researchers from the USA and The Bahamas conducted two sequential longitudinal, randomized trials of an evidence-based intervention spanning the adolescent years. The first trial involved 1360 grade-6 students and their parents with three years of follow-up and the second 2564 grade-10 students and their parents with two years of follow-up. Through grade-12, involvement in the combined child and parent–child HIV-risk reduction interventions resulted in increased consistent condom-use, abstinence/protected sex, condom-use skills and parent–child communication about sex. Receipt of the grade-6 HIV-prevention intervention conferred lasting benefits regarding condom-use skills and self-efficacy. Youth who had not received the grade-six intervention experienced significantly greater improvement over baseline as a result of the grade-10 intervention. The HIV-risk reduction intervention delivered in either or both grade-6 and grade-10 conferred sustained benefits; receipt of both interventions appears to confer additional benefits.
Resumen
Para abordar cuestiones globales relacionadas con la edad a la que realizar los esfuerzos de prevención del VIH dirigidos a jóvenes y los posibles beneficios adicionales de la participación de los padres, los investigadores de EE. UU. y las Bahamas realizaron dos ensayos secuenciales longitudinales y aleatorios, de una intervención basada en la evidencia que abarca los años de la adolescencia. El primer ensayo incluyó a 1360 estudiantes de 6.º curso y sus padres con tres años de seguimiento y el segundo s 2564 estudiantes de 10.º curso y sus padres con dos años de seguimiento. A lo largo del 12.º curso, la participación en la intervención del niño paternal y el niño combinadas de reducción de riesgo de VIH tuvo como resultado un aumento del uso regular de preservativos, abstinencia/sexo seguro, habilidades de uso del preservativo y comunicación sobre el sexo entre padres e hijos. La recepción de la intervención de prevención de VIH a los estudiantes de 6.º curso confirió beneficios duraderos en relación con las habilidades de uso de preservativos y autoeficacia. Los jóvenes que no habían recibido la intervención de 6.º curso experimentaron una mejora significativamente mayor respecto al nivel de referencia, como resultado de la intervención de 10.º curso. La recepción de la intervención de reducción de riesgo de VIH en 6.º o 10.º curso o en ambos confirió beneficios sostenidos; la recepción de ambas intervenciones parece conferir beneficios adicionales.
