Key result
DASHNa-CC dietary intervention fails to significantly reduce systolic blood pressure versus usual care.
Why the study?
There is a lack of culturally sensitive dietary interventions targeting Chinese Canadians despite unhealthy dietary behaviours being a key modifiable risk factor for hypertension in this population.
Does a culturally sensitive dietary intervention (DASHNa-CC) reduce blood pressure and improve health-related quality of life in Chinese Canadians with grade one hypertension?
Population
60 self-identified Chinese Canadians older than 45 years with grade one hypertension not on antihypertensive medications
Comparison
DASHNa-CC intervention plus usual care vs usual care alone
Design
Two-group pilot randomized controlled trial
Follow-up
8 weeks

Does a culturally sensitive dietary intervention (DASHNa-CC) reduce blood pressure and improve health-related quality of life in Chinese Canadians with grade one hypertension?
Mean Difference: -3.8
p-value: p=0.12
A culturally tailored DASH diet and sodium reduction intervention is feasible and may improve physical health scores and reduce systolic blood pressure in Chinese Canadians with grade one hypertension.
Zou et al. (2016) conducted an RCT in hypertension (n=60). DASHNa-CC intervention vs. usual care was evaluated on systolic blood pressure (MD -3.8 mmHg, p=0.12). The DASHNa-CC dietary intervention resulted in a 3.8 mmHg greater reduction in systolic blood pressure compared to usual care at 8 weeks (p=0.12).
