A Facebook-based Weight Loss Programme for Obese Adults in Hong Kong
Effects of a Facebook-based Weight Loss Programme for Obese Adults in Hong Kong
Tutkimuksen yleiskatsaus
Yksityiskohtainen kuvaus
Obese individuals often are at higher risk for developing non-communicable diseases such as diabetes and cardiovascular disease. The regular physical activity, healthy diet and social support have been shown to be beneficial for weight loss.
This is a two-arm parallel design randomized controlled trial for 6 months. Participants who completed the baseline assessment will be randomly allocated, after stratified by gender, to either a control group or Facebook-based intervention group. The control group will receive information on healthy eating, physical activity, obesity and cancer via three government printed health pamphlets. In addition to the government health pamphlets, the intervention group will receive a programme delivered through Facebook.
The interventions include participation in a private research group on Facebook for health education, self monitoring and social support. Participants will receive 12 weekly lessons related to nutrition, physical activity, Chinese food therapy, acupressure, weight loss. A registered nutritionist and a registered Chinese medicine practitioner will join the Facebook group as health partners. Both of them are also registered nurses.
Data collection will be carried out at baseline, 3 months and 6 months. Each time, both groups will complete online questionnaires and attend in-person anthropometric measurements
