Cognitive Function Predicts Risk for Clinically Significant Weight Gain in Adults With Heart Failure.
BACKGROUND
Few investigators have examined whether cognitive deficits predict poorer self-care of weight management recommendations and weight gain in adults with heart failure.


OBJECTIVE
The purposes of this study were (1) to examine whether cognition is associated with adherence to daily weighing and weight gain incidence and (2) to explore self-reported symptom perception and management when a weight increase occurs.


METHODS
In this observational study, participants completed neuropsychological testing, were given an electronic scale, and were instructed to record their weight for 21 days. Data for 301 participants were collected at baseline and 3 weeks after weight monitoring.


RESULTS
At baseline, only 35% of the enrolled respondents knew when to call their physician for increased weight gain, and 37% of the analyzed sample (n = 110/301) experienced a clinically significant weight gain. Regressions tested whether baseline attention, executive function, or memory predicted adherence to daily weighing and the likelihood of weight gain incidence. In unadjusted and adjusted covariate analyses, none of the cognitive domains predicted adherence to daily weighing (P ≥ .375); however, all 3 cognitive domains predicted an increased risk of a clinically significant weight gain (P ≤ .05). Importantly, 65% of participants with a weight gain did not identify this symptom on self-report questions.


CONCLUSIONS
Although cognitive deficits are not associated with adherence to daily weighing, adults with cognitive deficits may be at an increased risk for experiencing a clinically significant weight gain, and most do not perceive symptoms.


CONCLUSIONS
Adults with heart failure require more than directions on self-care related to weight monitoring.
