Evaluation of a culturally tailored lifestyle intervention among Pasifika: a feasibility study.
Article in BMC nutrition, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPasifika, migrant populations from Oceania in Australia, experience high prevalence of diabetes and obesity. Lifestyle interventions targeted at weight loss have shown beneficial effects in reducing the risk of type 2 diabetes (T2DM). To identify a weight loss component for a broader lifestyle clinical trial a study testing feasibility, acceptability and sustainability of a culturally tailored lifestyle intervention was delivered in Sydney, Australia.
methodsThe study is a before-and-after single-arm feasibility study informed by a combined socio-ecological model and the newly developed Cultural and Sustainability Assessment of Intervention (CSAI) framework. Participants were adults from a Samoan church community who volunteered and provided consent. The intervention was a weight loss challenge delivered over 12-week sessions using 12 lifestyle messages targeting physical activity and healthy eating habits with an additional message on planning and tracking goals. Implementation was delivered by a peer-support and volunteer structure. The primary outcome was change in weight (kg) with secondary outcomes of change in physical activity and dietary behaviour and HbA1c, amongst others. Lead by the community, the intervention was repeated at 12-months.
resultsThere was sustained engagement in the intervention, with low attrition rates (5.2%) and low resource requirements. At baseline, n = 36/51 (71%); 34 completed pre-post measurements at 12 weeks. Significant reductions were found in primary outcomes of reduced (median difference [IQR]) weight = -3.4[6.7]kg, p = 0.01; BMI = -1.1[2.3] kg/m2, p = 0.002; and body fat (BF) = -3.5[6.9]%, p = 0.03. Secondary outcome improvements included increased physical activity (≥ 3 days vigorous exercise weekly) (χ
conclusionsResults of this single-armed study indicate feasibility of the 12-week competition-based WLC to elicit weight loss in a minority population, such as Pasifika. Community response attested to acceptance and viability of the support structure. Opportunities exist to revise materials and use the CSAI to design culturally appropriate and tailored interventions to better engage Pasifika and minority populations.
