Guidelines for chronic kidney disease (CKD) management recommend healthy behaviors to mitigate disease progression, but behavior engagement is low. Identifying predictors of behavior engagement could inform strategies to increase healthy behaviors.
Using data from the Chronic Renal Insufficiency Cohort Study, potential predictors of behavior engagement included demographics, clinical and psychosocial factors, and behaviors at baseline. We dichotomized behaviors (recommended vs. not): smoking (no vs. current), body mass index (BMI <18.5 or >30 kg/m2), physical activity (>150 vs <150 minutes/week), diet (score of >2 vs 0-1), and hemoglobin A1c (<7 vs >7) if diabetes. Relationships between predictors and behaviors at 2 years were estimated by multivariable adjusted logistic regression models.
Among 5,209 participants at baseline, mean age was 60 years, mean eGFR was 48 ml/min/ml2, and 51% had diabetes. In multivariable analyses, baseline behaviors were most strongly associated with behaviors at 2 years (Table). Higher SF-12 physical component scores, which relate to better physical function and pain control, associated with recommended behaviors at 2 years. In models that did not adjust for baseline behaviors, no smoking was associated with older age, female sex, and non-White race, but the other behavior associations were not notably changed.
Interventions to increase healthy behavior engagement should be implemented and tested to evaluate whether they improve physical function and pain control, and possibly mitigate CKD progression.
