To the Editor Widman et al1 systematically review and meta-analyze the association of parent-based sexual health interventions with 6 adolescent sexual health outcomes by showing that parent-based interventions can significantly improve condom use and parent-child sexual communication but not delayed sexual activity. The findings of this meta-analysis1 may serve as a reminder of the emerging worldwide burden on the undesirable consequences of adolescent sexual decision-making or behaviors. However, we would like to voice 2 concerns regarding the methodologic aspects of this meta-analysis.
