Abstract
The Complete Health Improvement Program (CHIP) is effective in improving cardiovascular disease risk via the original live recorded DVD (DIS) and a revised studio recorded video versions (VIS), both presented in-person synchronously. The studio version was also presented in-person asynchronously (VIA) and virtually asynchronously (VVA). Assess the comparative effectiveness of four delivery methods of CHIP. Participants had biomarkers measured at baseline and after the 11th session: blood pressure (SBP, DBP), body mass index (BMI), fasting blood glucose (FBG), and lipid panel (TC, TG, LDL-c, HDL-c). ANCOVA was utilized to evaluate the interaction over time by group. Of 792 participants, the majority female in all groups (71.2-80.7%), mean age ranged 47.0–55.8 years. All methods showed significant changes in all biomarkers measured over time except for TG and SBP in VIA, TG in VVA and DBP in VIS. The time by delivery method interaction was significant for HDL-c (F value = 6.33, P = .0003), BMI (F value = 4.04, P = .007), systolic BP (F value = 4.33, P = .004). DIS was most effective in reducing HDL-c, BMI and systolic BP. While all four methods yielded significant changes in biomarkers, the in-person, synchronous delivery method produced the largest improvements.
