Abstract
Excess weight and obesity have high prevalence rates globally and are associated with significant morbidity and mortality rates. In the wake of the COVID-19 pandemic, telehealth emerged as an effective tool for promoting healthy behaviours in the management of chronic conditions. This study employed a three-month quasi-experimental design with pre- and post-intervention measurements, assessing the progress of 82 adults assigned either to an intervention group (IG) or a control group (CG). A total of 66 participants completed the study, with 33 in each group. The IG had access to a telehealth-based platform providing educational content on healthy lifestyle habits and were followed up both in-person and remotely. The CG were monitored as usual, i.e., at their primary care nurses' discretion. The IG exhibited a statistically significant reduction in weight, BMI, and abdominal circumference, along with improved adherence to a heart-healthy diet, specifically the Mediterranean diet, and higher levels of physical activity. The nurse-led intervention (Care4US+), utilising telehealth from primary care, has proven effective in enhancing healthy behaviours and reducing cardiovascular risk factors.
