Identifying DASH Adherence Patterns and Their Association With Dietary Behaviors Among Adults With Hypertension.

PMID 42080799WHAT IT FOUND
At baseline, adults with hypertension fell into three DASH diet groups: low, mixed, and relatively high adherence.
Intuitive eating habits differed, but blood pressure did not, so this analysis cannot link diet patterns to blood pressure.
Key findings
01Most DASH nutrient goals were not met, and sodium adherence was especially low at 5.65%.
02The sample split into three DASH adherence groups: 44 mixed pattern, 133 low adherence, and 124 relatively high adherence.
03Intuitive eating subscale scores differed across the adherence groups, but blood pressure did not.

What it does not show
It analysed only baseline data from 301 adults, so it cannot show whether adherence patterns changed over time or caused blood pressure differences. The sample was mostly female (65.1%), White (53.5%), and highly educated (43.7% postgraduate), limiting generalisability. The analysis was exploratory and p-values were not adjusted for multiple comparisons. Some subgroup demographic differences were not statistically significant despite apparent differences. The DASH score used nutrient goals, not actual foods, so it cannot say which foods or food groups drove each pattern. Blood pressure was measured remotely during Zoom visits using home monitors, not clinical office measurement.
Declared interests
The authors declared no conflicts of interest. Funding was from the National Institutes of Health.
The easy way to misread this
Do not read these groups as proof that intuitive eating improves DASH adherence or lowers blood pressure. The study was a baseline cross-sectional analysis, and blood pressure did not differ significantly across the adherence groups.
