Evaluation of an online cardiometabolic and weight loss program: a mixed methods study

Risk factors contributing to cardiovascular diseases (CVD) can be addressed through behavior modification, including changes in diet and physical activity. In 2021, The Wellness Institute (WI), located at Seven Oaks General Hospital, created a virtual cardiometabolic risk reduction program in response to COVID-19 pandemic public health restrictions, encompassing virtual health coaching and lifestyle education. The objective was to evaluate the acceptability, adherence, efficacy, and engagement of the WI online cardiometabolic and weight loss program. The study followed a mixed methods quasi-experimental design. A total of 93 participants enrolled. Quantitative measures including anthropometrics, blood chemistry, and lifestyle were assessed for changes via paired t tests at baseline and 16 weeks. Qualitatively, short answer questionnaires and three focus groups were completed to understand participants' experiences and program acceptability. We combined qualitative and quantitative data for analysis. Seventy-three participants (64 females, 87.7%) completed the final study visit (age 58 ± 11 years, weight 98 ± 20.9 kg). Of those, 98% attended all coaching sessions, would recommend the program, and reported the coaching sessions helped them stay motivated. A reduction in weight (5 ± 9 kg, p < 0.001), systolic blood pressure (6 ± 10 mmHg, p < 0.001), and diastolic blood pressure (4 ± 8 mmHg, p < 0.001) were observed. Lifestyle factors also improved, including increases in physical activity (p < 0.05). Most participants adhered to the program and found it acceptable. Completion was associated with an improvement in weight and blood pressure. These findings highlight the potential of virtual programming to contribute to improving lifestyle and health.
