PMID 32921518WHAT IT FOUND
Among 204 adults with COPD and hypertension, self-management formed three patterns: mostly good, mostly poor healthcare adherence, and mixed with poor activity and diet.
These are descriptive clusters, not evidence a tailored approach works.
Key findings
01Three self-management clusters were found: 95 patients had mostly good behaviors, 42 had generally poor behaviors, and 67 had a mix.
02Cluster 2 had generally poor behaviors: 7.1% were adherent to COPD medications and 21.4% to hypertension medications.
03Cluster 3 was the least physically active and had the poorest diet score, 24.7 out of 77.

What it does not show
Only baseline data were analyzed, so the clusters may change over time. The study included only adults with COPD and hypertension in urban primary care in New York City and Chicago, so it may not apply to other comorbidities or settings. The analysis was not theory-driven, and the authors say it needs validation in another group before practical interventions. The eight behaviors were treated as equally important, although medication adherence may matter more than flu vaccination. No health outcomes or treatment effects were tested, so the clusters do not show that any behavior pattern caused worse disease control.
Declared interests
The paper is listed as NIH extramural research support. One author received consulting honoraria from Sanofi, GlaxoSmithKline and Banook, and grants from Sanofi and Quorum; the authors state no other conflicts.
The easy way to misread this
Do not treat these clusters as proven ways to assign risk or guide treatment. The study only describes baseline behavior patterns in adults with COPD and hypertension from urban primary care, and the authors say the findings need validation before practical interventions.
