PMID 40786860WHAT IT FOUND
In 51 adults completing, a 12-week nurse-led Isan culture-specific behavior-change package lowered HbA1c from 8.65% to 7.95% and improved blood pressure control compared with usual care.
Key findings
01The combined HbA1c and blood pressure outcome favoured the intervention group over control at 12 weeks.
02At 12 weeks, 23.1% of intervention participants had HbA1c below 7.0%, 69.2% had systolic blood pressure below 130 mmHg, and 53.8% had diastolic blood pressure below 80 mmHg.
03No serious adverse outcomes related to the intervention were reported.

What it does not show
Only 51 of the 60 recruited participants were analysed, with 9 dropouts. Each group was one cluster from a different primary care unit, so site or staff differences could have affected the result. The trial was single-blind, so participants knew which group they were in. Participants were aged 40 to 59, had BMI below 30 kg/m2, had a mobile phone, and had no cardiovascular disease or conditions affecting blood pressure control, so the result may not apply to older, heavier, excluded or higher-risk patients. Intervention group participants who did not exercise were excluded. Outcomes were reported only at baseline and 12 weeks, so longer-term effects are not shown. The intervention was complex, so the contribution of any single component cannot be separated. Participants lacked home self-monitoring equipment, and some feared hypoglycemia.
Declared interests
The research was supported by a Chulalongkorn University scholarship. The authors declared no conflict of interest.
The easy way to misread this
Do not conclude that the Mor Lam dance, app, or nurse education alone improved HbA1c and blood pressure. The intervention group also received interactive classes, diet coaching with sugar, oil and salt limits, carb counting, glycemic index and label reading, Soeng Isan Dance exercise, medication use review, nurse consultations, peer and village health volunteer support, reminders, pedometer monitoring, and home visits. Home visits were given to both groups. Because the two groups also came from different primary care unit clusters, the contribution of any single component cannot be separated.
