Adolygiad Systematig
Mae'r awduron yn datgan "To assess the effectiveness of universal, selective, and indicated family‐based prevention programmes in preventing alcohol use or problem drinking in school‐aged children (up to 18 years of age). Specifically, on these outcomes, the review aimed: • to assess the effectiveness of universal family‐based prevention programmes for all children up to 18 years (‘universal interventions’); • to assess the effectiveness of selective family‐based prevention programmes for children up to 18 years at elevated risk of alcohol use or problem drinking (‘selective interventions’); and • to assess the effectiveness of indicated family‐based prevention programmes for children up to 18 years who are currently consuming alcohol, or who have initiated use or regular use (‘indicated interventions’)."
Mae'r awduron yn datgan "We included 46 studies (39,822 participants), with 27 classified as universal, 12 as selective, and seven as indicated. We performed meta‐analyses according to outcome, including studies reporting on the prevalence, frequency, or volume of alcohol use. The overall quality of evidence was low or very low, and there was high, unexplained heterogeneity. Upon comparing any family intervention to no intervention/standard care, we found no intervention effect on the prevalence (standardised mean difference (SMD) 0.00, 95% confidence interval (CI) ‐0.08 to 0.08; studies = 12; participants = 7490; I² = 57%; low‐quality evidence) or frequency (SMD ‐0.31, 95% CI ‐0.83 to 0.21; studies = 8; participants = 1835; I² = 96%; very low‐quality evidence) of alcohol use in comparison with no intervention/standard care. The effect of any parent/family interventions on alcohol consumption volume compared with no intervention/standard care was very small (SMD ‐0.14, 95% CI ‐0.27 to 0.00; studies = 5; participants = 1825; I² = 42%; low‐quality evidence). When comparing parent/family and adolescent interventions versus interventions with young people alone, we found no difference in alcohol use prevalence (SMD ‐0.39, 95% CI ‐0.91 to 0.14; studies = 4; participants = 5640; I² = 99%; very low‐quality evidence) or frequency (SMD ‐0.16, 95% CI ‐0.42 to 0.09; studies = 4; participants = 915; I² = 73%; very low‐quality evidence). For this comparison, no trials reporting on the volume of alcohol use could be pooled in meta‐analysis. In general, the results remained consistent in separate subgroup analyses of universal, selective, and indicated interventions. No adverse effects were reported."
Mae'r awduron yn datgan "The results of this review indicate that there are no clear benefits of family‐based programmes for alcohol use among young people. Patterns differ slightly across outcomes, but overall, the variation, heterogeneity, and number of analyses performed preclude any conclusions about intervention effects. Additional independent studies are required to strengthen the evidence and clarify the marginal effects observed."
