RESUMO
Chemoprophylaxis against tuberculosis with isoniazid for 1 year is very useful, but patient compliance is very low. A controlled clinical trial was performed to evaluate the efficacy of three alternative health education strategies and to observe which of them improves compliance with antituberculosis chemoprophylaxis in healthy tuberculin-reactor children. Although all three strategies achieved positive, statistically significant results as compared with the control group, that performed by nursing personnel at the patient's home is the most effective, followed by that performed by the same health professionals by telephone. The least effective strategy by far was that performed by the physician in his surgery.

Antituberculous chemoprophylaxis with isoniazide during a period of one year is very useful although it is not readily accepted. A community trial is designed in order to test if three health education interventions increase patients compliance with such treatment in case of tuberculin positive children who are not ill. The two interventions performed by nurses, one by phone, and the second one by a home visit, resulted in statistically significant difference when compared to the control group. This did not occur, however, with the intervention performed by the doctor in his office. A cost-effectiveness study demonstrates that the most efficient intervention has been the phone call.
