PMID 32274808WHAT IT FOUND
In 60 American Indian families with child asthma, no smoking at home and higher maternal confidence were linked to better control.
Maternal depressive symptoms were linked to more effort, but not to confidence.
Key findings
01The adjusted odds of asthma being adequately controlled were 14.43 times greater in families where no one smoked in the home than in families where at least one member smoked.
02Each one-point higher score for mothers' perceived ability to manage asthma was associated with 1.159 times higher adjusted odds of adequate control.
03Maternal depressive symptoms were not significantly related to perceived management ability (r = -.21, p = .100), but were significantly related to perceived management effort (r = .27, p = .035).

What it does not show
The study included only 60 families from one American Indian group in rural southeastern North Carolina, so it may not apply to other communities. It was cross-sectional, so it could not show that smoking, caregiver confidence, effort, or depressive symptoms caused better or worse asthma control. The sample was underpowered for some relationships, especially between management effort and asthma control and between maternal depressive symptoms and family management. Some measures had not been validated in American Indian populations, and the management effort scale had internal consistency of .68, slightly below acceptable. The study relied on questionnaires and mother reports.
Declared interests
The authors declared no potential conflicts of interest. The article is labeled as supported by NIH extramural and non-U.S. government research support.
The easy way to misread this
Do not read the 14.43 times greater adjusted odds as proof that removing smoking from the home will improve asthma control. This was a cross-sectional study of 60 families, so it shows an association, not a cause.
