Description of intervention(s) / exposure
The programme to be observed is called Buttabean Motivation (BBM Motivation/BBM) which runs a variety of free and open physical activity sessions for groups of individuals and families. BBM's vision is to reduce obesity amongst Maori and Pacific people in New Zealand, and to enable them to choose a sustainable healthy and active lifestyle. The BBM environment is communal, highly supportive, and non-judgmental, so that people feel comfortable participating in physical activity programmes in a safe environment.
We will conduct an observational impact evaluation of the no-cost BBM programmes by following a cohort of members for 24 months. We will not examine the details (purpose, intensity, quality, length, etc) of specific programmes which are highly variable, but rather the longitudinal (2-year) impact on health as a result of engaging with BBM. The training sessions are run by 20 BBM Community Leaders (trainers) who are trained in-house by founder Dave Letele who is PT Level 4 qualified. BBM trainers have gained accreditation through Skills Active Aotearoa with Exercise Industry PT Level 3 NZQA qualification. Many of the trainers have come through BBM as members attending training sessions and the training of trainers at BBM is constant.
For six days a week, BBM conducts over 20 free weekly group sessions of exercise routines, attended by 1000 people in South, West, and Central Auckland. Members of the public register to become BBM members through the BBM website, a process called on-boarding, which allows BBM to track members’ attendance. Once registered, sessions are advertised on the MindBody app where members book a spot for specific sessions. Members must remove their booking if they are subsequently not able to attend. Attendees are signed in electronically by BBM staff. Sessions are carried out either in BBM’s own training facilities or in public spaces ranging from parks, halls, and even carparks. The sessions are designed so that minimal training equipment is not needed where only body movement is required. The intensity of all exercise routines begins with a brief low intensity warm-up, are mostly vigorous throughout, but allow for regression (lower intensity) or progression (higher intensity) training suited to individual capacity. Timing of routines vary from 45 to 60 minutes of 6- to 8-minute sets with 30 second to 1 minute intervals.

Statistical methods / analysis
There is no control group but there is very strong evidence that a non-intervention counterfactual of no weight change is plausible since the average natural trajectory of people with obesity is no change or slow increases in weight. A sustained weight loss of 5-10 percent is clinically meaningful for health benefits, even if people remain overweight or even obese. The General group will include new entrants who will form a cohort with baseline and follow up data. The numbers of new entrants are very high (since reopening after Covid-19 lockdown, BBM had 158 new registrations over 19 days). These two cohorts will have simple analyses (t-tests for follow up minus baseline data) to define the standard metrics.

Summary
Brief summary
The primary purpose of this study is to estimate the effectiveness of the Buttabean Motivation (BBM) programme for achieving sustained physical activity participation, weight loss and improved health outcomes for Pacific and Maori participants. The study will use a co-design approach, where researchers will work with personnel and members of BBM to develop the study questions, research processes and information delivery. Consistent with BBM’s Pacific community culture, the study incorporates the Pacific Fonofale model of inquiry which incorporates the values and beliefs of Pacific cultures. Thus, health encompasses different foundations of life including family, cultural values and beliefs, spiritual, physical, mental, and other influences such socioeconomics.
The main hypothesis is that BBM will create valuable, sustained average weight loss (greater than or equal to 5% of baseline weight), and cardiovascular benefits for its members. Secondary hypotheses include that programme participation will result in participants meeting healthy activity and eating guidelines; and that BBM members will experience measurable personal and social benefits such as improved quality of life and social relationships.
The overall aim is to evaluate the effectiveness of BBM for sustained health and wellbeing outcomes among mostly Pacific and Maori participants. This will be achieved by evaluating the effectiveness of BBM's free community exercise programmes.
The first objective of the study is to estimate the medium- and long-term (12 and 24 months) impact on body weight. This will involve recruitment of a cohort of BBM members whose height and weight will be measured at baseline, and at six, 12 and 24 months after baseline.
The second objective will be to evaluate change in participant wellbeing and health conditions after 24 months engagement with BBM. This will involve surveying participants at baseline and two years after. The survey includes using the Hua Oranga questionnaire which measures wellbeing from physical, emotional, spiritual, and social relations dimensions on a Likert-type scale. In addition to demographic information (age, ethnicity, sex), other information to be collected in the survey will include health conditions blood pressure, diabetes, sleep apnoea and heart disease.
The third objective is a systems analysis of the BBM programme to understand the strengths and challenges of delivering a holistic and sustained service for the community. A series of Group Model Building workshops will be carried out with BBM staff to build the systems logic model for the BBM programme. The model will be initiated in year one and be reviewed annually. It will serve as an agreed theory of change for BBM and help evolve effective programme value by providing the basis for continuous quality improvements.
