Brief summary
The general research question posed was 'How effective is a healthy lifestyle intervention using behavioural change strategies in the prevention of Type 2 Diabetes Mellitus (T2DM)?'. The main aim was to assess the effectiveness of a healthy lifestyle intervention implemented for 12 weeks via face-to-face group sessions and by using social media tools (Facebook and WhatsApp) for young adults at risk of T2DM. The hypothesis was that this healthy lifestyle intervention may be effective in terms of initiating an increased physical activity (PA) level and a healthy balanced dietary intake resulting in improvements of other T2DM risk factors at 12 weeks.
Detailed description
The specific research question posed was 'Is a healthy lifestyle intervention using Social Cognitive Theory (SCT)-based PA and dietary strategies implemented for 12 weeks through face-to-face group sessions and social media tools effective in the initiation and maintenance of increased PA level and healthy balanced dietary intake, resulting in improvements of T2DM risk score, anthropometrics, metabolic parameters and SCT-related psychosocial factors among Bruneian young adults at risk of T2DM?'. Study design was two-arm parallel, stratified with simple randomisation, and assessor-blinded randomised controlled trial. Participants were randomly allocated into intervention group and control group. Participants were students and alumni of Universiti Brunei Darussalam and Universiti Teknologi Brunei who were overweight-obese at risk of T2DM with a mean age of 23.1 (2.48) years old. Intervention group went through a healthy lifestyle intervention using evidence-based SCT strategies emphasising on PA and diet for 12 weeks, while the control group only received leaflets on healthy lifestyle with no further guidance. Outcomes measured were changes from baseline at week 0 to post-intervention at week 13 between intervention and control groups. Outcomes were changes in diabetes risk score, anthropometrics, metabolic parameters, PA, dietary intake and SCT-related psychosocial factors, with repeated-measures ANOVA as the main analysis.
Interventions
BEHAVIORALHealthy lifestyle intervention
The main goal was to provide knowledge and skills for targeted population in order for them to adapt healthy lifestyle throughout their life. At the end of intervention, participants were expected to be fully equipped with necessary knowledge and fundamental skills in adapting and maintaining healthy lifestyle throughout their life. Gradual improvements were emphasised and at least 5% loss of initial body weight was expected, aiming for at least 0.5% loss in the first month. It was divided into three phases (preparation, implementation, maintenance) focusing on PA and diet, in which self-efficacy enhancement and self-regulatory skills were emphasised during the first month of intervention.

Intervention model description
Participants were randomly allocated into two groups: one group with intervention (intervention group) and another group without intervention (control group). Intervention group went through a healthy lifestyle intervention using evidence-based SCT strategies emphasising on PA and diet for 12 weeks via face-to-face sessions and social media tools, while the control group only received leaflets on healthy lifestyle with no further guidance.
