Influence of previous health guidance history: impact and limitations of a single health guidance session

Abstract

Objectives: Metabolic syndrome (MS) is a significant health concern in the working-age population. Since 2008, Japan has mandated health insurers to implement Specific Health Checkups to identify individuals with MS and preliminary groups, making Specific Health Guidance (SHG) compulsory for these groups. People receiving SHG multiple times is increasing as it is conducted as an annual public program. Therefore, we evaluated the influence of a health guidance history on the effectiveness of subsequent guidance. Methods: Using data from 10,191 participants in the 2017 Motivational Health Guidance (a type of SHG involving a single session), this longitudinal study assessed the changes in health checkup findings from 2017 to 2018. Participants were categorized based on their previous year’s (2016) SHG eligibility and participation: Group 1 (n=3,903) met the 2016 SHG criteria and participated, Group 2 (n=2,305) met the criteria but did not participate, and Group 3 (n=3,983) had no MS risk factors and did not need to participate in the 2016 SHG. Results: The entire cohort and Groups 2 and 3 exhibited significant weight loss after 1 year. Group 1 showed a significant negative association, with a 3% (odds ratio [OR] 0.64; 95% confidence interval [CI], 0.55–0.75) and 5% body weight loss (OR 0.66; 95% CI, 0.54–0.81) than Group 3. Men in Group 1 showed a significant association with new-onset MS (OR 2.56; 95% CI, 1.93–3.40). Conclusions: The findings suggest that participants with a history of health guidance in the previous year may have low rates of achieving weight loss and a high incidence of new-onset MS after 1 year.
