A cross-sectional analysis of associations between lifestyle advice and behavior changes in patients with hypertension or diabetes: NHANES 2015–2018

Abstract

Clinicians supporting patients in lifestyle behavior change is an important strategy to help reduce chronic disease burden. Using National Health and Nutrition Examination Survey (NHANES) data from 2015 to 2018, this study assessed rates of and associations between patient-reported receipt of lifestyle behavior change advice and corresponding self-reported behavior change for four different lifestyle behaviors: 1) weight loss, 2) increase physical activity, 3) reduce sodium, and 4) reduce fat and calories. Adult survey respondents with hypertension and/or diabetes (n = 4716) who received lifestyle advice ranged from 43% to 58%, with the most common recommendation being to increase physical activity. Between 61% and 73% of respondents reported currently modifying health behaviors, with the greatest number reporting weight loss. Multiple logistic regression models were used to test associations for each lifestyle behavior advice-behavior change pair, adjusting for demographic characteristics. Compared to those who received no advice, respondents who received advice had significantly higher odds of reporting losing weight (aOR: 1.93; 95% CI: 1.51, 2.48); increasing physical activity (aOR 2.02; 95% CI: 1.73, 2.37); reducing dietary sodium (aOR 4.95; 95% CI: 3.93, 6.25); and reducing intake of fat/cal (aOR 3.57; 95% CI: 2.86, 4.45). This study utilized population level data to lend further evidence that provider advice about lifestyle behaviors for patients who have hypertension or diabetes may influence patient behavior. However, prevalence of advice is low, and differences in rates of behavior change exist across socioeconomic status and race/ethnicity, indicating a need to further research how providers might better support patients with varying social needs.
