Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants with a recently diagnosed prediabetes and/or diabetes (defined by having an HbA1c test in the last 12 months) will be invited to join the study from Phase 1 of the study, that focuses on co-designing the intervention programme. The co-design programme will be delivered to the community over a 24 week period, every week for up to 2 hours per meeting. These co-design meetings will be conducted in face-to-face workshops, delivered by the Community Coordinator (who is already trained in the co-design methodology).

Phase 2 study participants include the same participants with prediabetes/diabetes diagnosis from phase 1, and their families (approximately 100 individuals >18years old).
It is anticipated that the co-designed life-style based and behavioural change intervention programme may include weekly activities, such as increased physical activities (eg. organised community 4km walks, community-based fitness classes), and behavioural change activities (eg. educational modules related to cooking and nutritional skills). The intervention programme will be measured at baseline (time-point 1: week 0) and at post-intervention (time-point 2: week 24).

Data collection at Time-point 1:
• Socio-demographic data: date of birth, gender, ethnicity, highest education level, and annual household income;
• Anthropometry: self-reported weight (kilograms) and height (centimetres); blood pressure; diet diversity
• Health status: self-reported health condition(s) defined as being told by a doctor that they have this condition, including prediabetes, diabetes, and heart disease;
• Holistic wellbeing (for Pasifika participants): spiritual, physical, mental and family wellbeing measured by 10-items based on the Fonofale Model. All answers are measured on a 5-point Likert scale.

Data collection at Time-point 2:
Anthropometry: self-reported weight (kilograms) and height (centimetres); blood pressure; diet diversity
• Health status: self-reported health condition(s) defined as being told by a doctor that they have this condition, including prediabetes, diabetes, and heart disease;
• Holistic wellbeing (for Pasifika participants): spiritual, physical, mental and family wellbeing measured by 10-items based on the Fonofale Model. All answers are measured on a 5-point Likert scale.

Outcomes
Primary outcome [1] 326824 0
The primary outcome is family adherence to a co-designed healthy lifestyle behavior change programme to reduce prediabetes and diabetes levels, over a 6 month period. This will primarily be determined by a positive change in anthropometric measurements (eg. decrease in weight (kg), reduced BMI status, and improved dietary behaviors).
Timepoint [1] 326824 0
At baseline (week 0) and post-intervention (week 24), Phase 1 / year 1 of the study, data collection includes:
Anthropometry: self-reported weight (kilograms) and height (centimeters); blood pressure; diet diversity.

Positive change in anthropometric measurements (eg. decrease in weight (kg), reduced BMI status, and improved dietary behaviors).
Primary outcome [2] 327261 0
Improved physical activity
Timepoint [2] 327261 0
At baseline (week 0) and post-intervention (week 24), Phase 1 / year 1 of the study, data collection includes:

Improved physical activity level as determined by the Physical Activity (using 6 minute walking test)
Primary outcome [3] 327263 0
Overall improved health and wellbeing of the Pacific participants as a result of the intervention programme
Timepoint [3] 327263 0
At baseline (week 0) and post-intervention (week 24) using the FonoFale Health and Wellbeing questionnaire
Secondary outcome [1] 392813 0
To examine whether co-designing a family diabetes intervention programme is practically feasible for Pacific families.
Timepoint [1] 392813 0
The secondary outcome will involves mini-focus groups (phase 3 / year 2 of the study). end date 30 October 2022. The outcome will be assessed in relation to implementation of the program 6 months post intervention of phase .

Summary
Brief summary
The distribution of and access to resources to enable better health and wellbeing for Pacific families with members who have long-term conditions, continues to be unequal, and lacks cultural responsiveness that is acceptable to Pacific groups living in hard to reach regions. This project uses a co-design approach, and the central research questions are: Is a family-centered diabetes intervention programme for Pacific families an effective approach to prevent diabetes? The impact of the overall research programme will provide a methodological approach that can be replicated in other communities and ethnic groups.
