Key finding
−0.40 mmol/L (95% CI −0.51 to −0.28, p<0.001)
This study tested a community lifestyle programme for adults with prediabetes in Malaysia. After 12 months, people in the programme had lower blood sugar, better cholesterol, smaller waists, and improved quality of life compared to those receiving usual care. The programme was delivered through existing community volunteers.

Study focus
This study tested a community lifestyle programme for adults with prediabetes in Malaysia. After 12 months, people in the programme had lower blood sugar, better cholesterol, smaller waists, and improved quality of life compared to those receiving usual care. The programme was delivered through existing community volunteers.
Type 2 diabetes rates are rising rapidly in developing countries like Malaysia. This study shows that a lifestyle programme delivered through existing community volunteers can effectively reduce multiple diabetes risk factors in adults with prediabetes. The community-based model is practical for wide-scale dissemination in settings with limited healthcare resources.
Non-randomised (quasi-experimental) design with potential selection bias Uneven group sizes (122 vs 146) due to non-random allocation Single geographic region in Malaysia — may not generalise broadly No long-term follow-up beyond 12 months
↓ Fasting glucose −0.40 mmol/L, HbA1c −0.24%, and 2-hour glucose −0.58 mmol/L vs usual care (all p<0.001)
↓ Diastolic BP −2.63 mmHg, waist −2.44 cm; ↑ HDL cholesterol +0.12 mmol/L
↑ Quality of life: physical +6.51, mental +7.79 points (both p<0.001)
