Tobacco counseling for youth or adults can reduce the prevalence of smoking cigarettes during adult years, according to a study published in the January/February issue of the Annals of Family Medicine.

Researchers conducted a microsimulation analysis to estimate the health impact and cost-effectiveness of tobacco counseling of youth and adults in a U.S. birth cohort of 4,000,000.

The researchers found that the model predicted that annual counseling for youth would reduce the average prevalence of smoking cigarettes by 2.0 percent during adult years, whereas annual counseling for adults would reduce prevalence by 3.8 percent, compared with no tobacco counseling.
