Tale of two churches: differential impact of a church-based diabetes control programme among Pacific Islands people in New Zealand.
OBJECTIVE
To compare the impact on weight and exercise of a 2-year church-based diabetes risk reduction programme in four churches in South Auckland, New Zealand.


METHODS
A prospective non-randomized controlled study of a modular lifestyle and diabetes awareness intervention programme applying community development principles. The study involved four complete church congregations, two Samoan and two Tongan, with 516 participants at commencement. Risk of Type 2 diabetes is high among both ethnic groups.


RESULTS
Overall, 285 subjects were available for their second assessment. In one intervention church, weight gain was controlled (vs. control 0 +/- 4.8 vs. +3.1 +/- 9.8 kg, respectively; P=0.05), diabetes knowledge (+46 +/- 26% vs. +4 +/- 17%; P<0.001) and regular exercise (at least 3 days per week: +22% vs. -8%; P=0.032) increased and readiness to change weight (P=0.007) shifted towards maintenance (e.g. maintenance +41% vs. +8%, respectively). The other intervention church increased diabetes knowledge (+19 +/- 24 vs. +8 +/- 25; P<0.024), but no other significant personal changes occurred. Attendance and perceived utility of the programme were greater in the first intervention church.


CONCLUSIONS
A moderate intensity, community-based, structured diabetes awareness and lifestyle programme can reduce diabetes risk, but increasing diabetes knowledge alone is not necessarily associated with healthier lifestyle choices. Continuous and detailed monitoring of penetration of interventions may be essential to help guide the timing of interventions and identify the need for additional strategies to increase participation and motivation.
