A summary of the article is shown below:

Effort is required to meet the Healthy People 2020 goal of tuberculosis (TB) disease reduction to 1 new case per 100,000 in the United States (US) and reduce burden among those disparately affected. Preventing new cases by reducing conversion from latent TB infection (LTBI) to infectious disease is one approach to reducing disease burden. This paper describes the outcome of a trial designed to determine if LTBI-positive youth prescribed daily Isoniazid with peer counseling would achieve higher adherence than attention control participants. The paper also compares adherence to a previous trial. 263 students age 15.9 years (SD = 1.2), 51.7% female, 96.2% Latino, 43.7% foreign-born were randomly assigned to condition. Adherence was measured by self-report validated by metabolite analysis. Outcome analyses used number of pills taken and proportion of youth consuming 80% of medication. There was no significant difference by condition for either analysis. Thirty-seven percent of adherence participants completed treatment versus 40% of controls. Without a usual-care control group we were unable to determine whether conditions were equally effective or ineffective. The study’s inability to pay for treatment resulted in the intervention being tested in the context of compromised access to care. Still to be determined is whether same-age peers can influence adherence among Latino adolescents.Trial registration: Identifier NCT00233168.
