Effect of one-time brief additional counseling on periodic health examination for 40- and 66-year-olds: 2-Year follow up of 101 260 participants.

AIM: The aim of the present study was to evaluate whether the effect of one-time brief additional counseling in periodic health examinations (PHE) through the National Screening Program for the Translational Ages in Korea is sustained after 2 years.

METHODS: We collected data from National Screening Program for the Translational Ages participants in 2007 and 2008. To evaluate behavior change after 2 years, we collected the participants' health behavior data 2 years later (2009 and 2010). We defined the basic group as participants who only received PHE, and the additional group as received PHE and counseling. We carried out propensity score matching to ensure that additional counseling was the only different variable affecting health behavior between the two groups.

RESULTS: After propensity score matching, 50 630 remaining matched participants were matched for each group. Of these participants, 26.5% (26 855/101 260) were aged 66 years, and 60.9% (61 653/101 260) were men. The additional group showed a significant increase in odds of smoking cessation among the 66-year-olds (adjusted OR 1.173, 95% CI 1.003-1.372). This effect was significant, especially when the participants did not have hypertension or hypercholesterolemia (adjusted OR 1.193, 95% CI 1.000-1.423 for hypertension and adjusted OR 1.188, 95% CI 1.009-1.398 for hypercholesterolemia). However, there was no significant association for alcohol drinking and regular exercise.

CONCLUSIONS: The effect of one-time brief counseling added to a PHE in cigarette smoking was observed only among the 66-year-olds. However, the effect was so small that it is doubtful to be clinically relevant. Repeated counseling is required to sustain the effect of the initial motivation of counseling.
