Outcomes are reported from the piloting of a personal trainer approach using a Māori Community Health Worker (MCHW) to help facilitate intensive lifestyle change among 5240 non-pregnant Māori family members without diabetes from 106 rural and 106 urban geographical clusters. In a pilot study (Vanguard Study), 160 participants were weighed before and during MCHW intervention (consisting of healthy lifestyle messages, toolkit and delivery) and compared with 52 participants weighed immediately before intervention and with 1143 participants from the same geographical area. The participants and MCHW considered that the intervention was acceptable. Significant weight loss occurred during the Vanguard Study among all participants (−1.3 kg; p<0.001), and after screening and during the study among the 27 participants diagnosed with impaired glucose tolerance/ impaired fasting glucose (5.2 kg; p<0.01).
