Effects of a two-night hospitalization program as a specific health guidance on obesity and cardiovascular disease risk factors.

Background: To assess the effects of a two-night hospitalization program conducted at our hospital as part of a domestic health guidance system. This program is designed for lifestyle modification within a health checkup framework for metabolic syndrome. Methods: This is a single-center, retrospective observational study. We reviewed the medical records of 170 subjects who completed the two-night hospitalization program between June 1, 2019, and October 31, 2023. The ideal dietary caloric intake was calculated based on standard body weight (kg) × 25 kcal/kg. Participants were advised to maintain a regular lifestyle and received face-to-face instruction from nurses, nutritionists, physiotherapists, technicians, and physicians. We instructed the patients to visit the outpatient clinic twice, one month and three months after discharge. We compared body weight, systolic and diastolic blood pressure, and various metabolic parameters from those recorded before the program to the final outpatient visit after the program. Results: Roughly half of the participants had been previously diagnosed with obesity and metabolic syndrome. At the second outpatient visit after completing the program, participants showed a significant body weight reduction (71.6 ± 13.5 kg vs. 70.1 ± 13.3 kg, Conclusions: The findings suggest that the two-night hospitalization program may offer significant benefits for managing coronary risk factors associated with metabolic syndrome.
