Since April 2008, health insurance providers have carried out health checkups and health guidance (HCHG) to insured individuals between the ages of 40 and 74. The purpose of this study was to find effective message channels to lead people to aware what HCHG is. The 525 respondents were obtained from the registrants of a Japanese social research company and were above 40 years of age (male : n=265, female : n=260, 48.4±5.5 years) . This longitudinal survey was carried out by using an internet-based questionnaire. We did the survey in November 2007 (T1) and December 2008 (T2) . The rates of awareness of HCHG were 47.8% at T1 and 77.3% at T2. The awareness level was significantly increased (p<.001) . Major factors regarding the degree of awareness about HCHG were female (OR=3.74, 95%CI=1.44-9.66) and participation in health check up (OR=1.91, 95%CI=1.05-3.48) , and health information from papers in hospital and pharmacy (OR=2.37, 95%CI=1.14-4.90) . The number of reference message channels in the awareness group was significantly higher than that in the no awareness group (t (272) =4.82, p<.001).
