Effectiveness of a Dutch community-based alcohol intervention: Changes in alcohol use of adolescents after 1 and 5 years

Abstract

The Dutch community intervention appears to be effective on the short- and long-term in reducing the prevalence of recent alcohol use and binge drinking of (underage) adolescents in the second grade of high school.

Whole‐of‐community interventions to reduce population‐level harms arising from alcohol and other drug use: a systematic review and meta‐analysis

“…Most were cluster‐randomized controlled trials ( n = 13) , and targeted AOD use in young people ( n = 17) . Trials were conducted in the United States ( n = 13) , the Netherlands ( n = 2) , Australia ( n = 2) and one each in Sweden , Italy , Canada , Iceland , Sri Lanka , South Africa and China . Sample sizes (of those directly surveyed) ranged from 142 to 123 235 (median = 5024); however, given the community focus, the total number of people exposed to the intervention in each study was unknown, but likely to be larger.…”

“…Assessments of the risk of bias of included trials ( n = 24) is shown in Supporting information, Figs S1 and S2. Most trials were at high risk of bias for allocation sequence generation ( n = 14) and selective reporting ( n = 12) . Eight trials were found to be at high risk of bias for other causes, including significant lack of power, omitting details on statistical significance level, nesting of an intervention within a larger intervention trial, outcome data being collected for males only, evaluating changes within intervention groups rather than between intervention and control groups, not accounting for clustering and omitting details of certain outcomes due to significant attrition.…”

When examined by overall risk of bias rating, most studies ( n = 13) were rated as having an overall high risk of bias , n = 7 had an overall rating of unclear due to insufficient reporting of data and just four had an overall rating of low .…”

Intervenciones para disminuir el consumo de alcohol en adolescentes: una revisión sistemática

“…El total de artículos incluidos en la RS fueron 61, 34 de ellos corresponden a estudios cuasi-experimentales (5)(6)(7)(8) 21 estudios experimentales ECA (44-64) 3 Meta análisis de estudios cuasi-experimentales (9,11,13) y 3 de ECA. (10,65,66) En relación a los ECA solo el 8.1% (f=5) reportaron apegarse al CONSORT statement (Consolidated Standards of Reporting Trials) (20,44,52,54,60) Respecto a la población objetivo de las intervenciones el 60.6% (f=37) fueron dirigidas a adolescentes; 21.3% (f=13) a los adolescentes y sus padres; 8.1% (f=5) a adolescentes internados en una institución de salud por las consecuencias del alcohol; 3.2% (f=2) se aplicaron en adolescentes y jóvenes y 1.6% (f=1) solo a los padres o bien a adolescentes, padres y maestros En relación al lugar donde se aplicaron los estudios el 59% (f=36) fue en la escuela donde estudian los adolescentes, 11.4% (f=7) lo hicieron en la comunidad; el 3.2% (f=2) lo aplicaron en el ámbito rural y el 1.6% (f=1) lo realizaron en el medio indígena.…”

“…(5)(6)(7) El uso y abuso de alcohol entre los adolescentes preocupa cada vez más a diversos países, ya que reduce el autocontrol del individuo e incrementa de manera significativa los comportamientos de riesgo, como las relaciones sexuales no protegidas, por lo tanto embarazos no deseados y además de alto riesgo. Es una de las principales causas de lesiones, como los accidentes de tránsito, violencia, y muertes prematuras.…”
