[Cost-effectiveness of health promotion in Chile. Experience with "Mirame!" program].
BACKGROUND
"Mirame!" program was launched in Chile in 1993, to promote a healthy life style at school age.


OBJECTIVE
To evaluate cost-effectiveness of this program.


METHODS
Fifth and sixth grade school children, from 5 selected municipalities of the Metropolitan Region were studied. The design was a quasi-experiment with an intervention (IP, 1,435 children) and reference population (RP, 1,246 children). Tobacco (T-C) and alcohol (OH-C) consumption were the indicators. A baseline survey was done in 1993 and repeated in 1996 in both groups. The criterion of Net Change was applied to assess effectiveness. For cost evaluation, an institutional perspective was considered. Direct municipal administration and "Mirame!" program costs were analyzed and incremental costs were calculated, using reference municipalities as controls. A univariate sensitivity analysis was done based on the beneficial discount rate and cost discount rate. Cost effectiveness coefficient was calculated.


RESULTS
The incremental cost per each boy and girl prevented from OH-C was 112 US dollars (103.6-114.3) and 132 US dollars (129.9-133.3) respectively. The figures for each boy and girl prevented from T-C was 154 US dollars (142.7-157.4) and 130 US dollars (122.5-135.2) respectively. The program caused an additional cost per child, for the city hall of 11.7 US dollars in two years.


CONCLUSIONS
It is possible to apply health promotion interventions in schools with a good cost effectiveness in the short run.
