Comparison of Waist Circumference Changes Between Same-Day Company-Based Specific Health Guidance and Later Facility-Based Guidance

Abstract

This study compared changes in waist circumference between participants who received Specific Health Guidance on the same day as their health checkup and those who received counseling at a later visit. The study included 96 individuals classified as requiring motivational support in 2023. Participants were divided into a same-day group (n = 71) and a later-visit group (n = 25). Waist circumference and body weight were measured at baseline and after three months. The mean reduction in waist circumference was −0.37 cm in the same-day group and −3.4 cm in the later-visit group. Counseling records suggested that participants in the later-visit group had stronger motivation for behavioral change. The findings indicate that intervention timing and participant readiness may influence the effectiveness of Specific Health Guidance.
