Monitoring health and dietary behaviour during participation in an online lifestyle program

Abstract

study evaluated the implementation, acceptability and preliminary efficacy of an embedded video call (VC) platform and dietitian consultations to the ClickFit weight loss program. Methods: Initially participants were randomly allocated to one of two groups: (1) 6-week ClickFit program (CF only) or (2) 6-week ClickFit program+ two dietitian video consultations (CF + VC). Early technical issues with the VC platform resulted in inconsistent use. Therefore after the first 10 participants the remainder were allocated to the CF +VC group. Clinical and behavioural variables were assessed a baseline and following program completion. Process evaluation was also undertaken. Results: Eighteen participants (n = 5 CF only; n = 13 CF +VC) commenced the study (aged 21—60 years; 72% female, BMI 28.1± 2.2 kg/m2), with two withdrawals (CF + VC group). Within-group changes in weight and waist circumference were significant for CF + VC completers (−2.1± 1.9 kg and −4.1± 3.6 cm; p < 0.01) compared to CF only (−2.3± 2.4 kg and −1.5± 3.6 cm). Significant between-group improvements were found for the CF +VC group in overall diet quality and vegetable intake. For the CF +VC group, 70% of dietitian consultations occurred within the VC platform, with 1.8± 0.4 sessions/participant. Most (n = 10) agreed the consultations provided useful information on changing behaviours and improving confidence for weight loss. Conclusions: The addition of dietitian video consultations to a web-based weight loss program was acceptable and demonstrated preliminary efficacy over a 6 week period. The combination of an online program with tailored dietetic video support may address the logistical and systemic challenges associated with access to in-person obesity services. A large trial over a longer duration is required to determine the effectiveness of this treatment strategy for weight management.
