In response to the childhood obesity epidemic, numerous studies on school-based
Internet obesity prevention interventions have been conducted. The purpose of
this systematic review is to describe, synthesize, and evaluate the research on
school-based Internet obesity prevention programs for adolescents. Medline,
CINAHL, and PsycInfo were searched from January 1995 to August 2012 to locate
relevant studies. Ninety-one reports were initially identified, with 12 meeting
the inclusion criteria. Studies had variable control groups, program content,
and sample characteristics. Though few authors reported on implementation
processes or body mass index (BMI) outcomes, the majority of studies were
effective in improving health behaviors in the short term. Most studies were
judged to have a high or unclear risk of bias in at least two domains, thus the
quality of evidence for this body of literature is moderate. Further research is
needed to examine programs of longer duration, optimal dose and timing of
programs, cost-effectiveness, and mediators and moderators of intervention
outcomes. 相似文献
