A pilot urban church-based programme to reduce risk factors for diabetes among Western Samoans in New Zealand.

We have assessed the impact of a 2-year pilot church-base diabetes risk reduction programme on major lifestyle predictors of future Type 2 diabetes mellitus: exercise and weight control in a prospective non-randomized controlled study of a modular lifestyle and diabetes awareness intervention programme using a community development model. The study involved two complete church congregations from an ethnic group at high risk of diabetes (Western Samoans) (intervention church n = 78; control church n = 144). Weight remained stable (0+/-4.8 kg) in the intervention church but increased by 3.1+/-9.8 kg in the control church (p = 0.05). In the intervention church, there was an associated reduction in waist circumference (-4+/-10 cm vs +2+/-7 cm in control, p < 0.001), an increase in diabetes knowledge (46+/-26% vs 4+/-17% in control, p < 0.001) and an increase in the proportion exercising regularly (+22% vs -8% in control, p < 0.05). Consumption of key fatty foods was also reduced in the intervention church. We conclude that diabetes risk reduction programmes based upon lifestyle change, diabetes awareness, and empowerment of high risk communities can significantly reduce risk factors for future Type 2 diabetes.
