Health care providers are encouraged to prescribe lifestyle modifications for preventing and managing obesity and associated chronic conditions. However, the pattern of lifestyle advice provision is unknown. We investigate the prevalence of advised lifestyle modification according to weight status and chronic conditions in a US nationally representative sample.
Methods
Adults ages 20-64years (n = 11,467) from the National Health and Nutrition Examination Survey between 2011 and 2016 were analyzed, with weight status and chronic conditions (high blood pressure, high blood cholesterol, osteoarthritis, coronary heart disease, and type 2 diabetes mellitus). Lifestyle modification advice by health care providers included: increase physical activity/exercise, reduce dietary fat/calories, control/lose weight, and all of the above.
Results
High blood pressure (32.7%) and cholesterol (29.3%) were highly prevalent compared with osteoarthritis (7.4%), type 2 diabetes (5.7%), and coronary heart disease (3.7%). Those with type 2 diabetes received considerably more frequent advice (56.5%; 95% confidence interval [CI], 52.4%-60.6%) than those with high blood pressure (31.4%; 95% CI, 29.3%-33.6%) and cholesterol (27.0%; 95% CI, 24.9%-29.3%). Prevalence of lifestyle advice exhibited substantial increases with graded body mass index and comorbidity (all P < .001). After adjusting for comorbid conditions, advice was more commonly reported among women, those overweight/obese, nonwhite, or insured. A remarkably low proportion of overweight (21.4; 95% CI, 18.7%-24.3%) and obese (44.2%; 95% CI, 41.0%-47.4%) adults free of chronic conditions reported receiving any lifestyle advice.
Conclusions
Prevalence of lifestyle modification advised by health care providers is generally low among US adults with chronic conditions, and worryingly low among those without chronic conditions, however overweight or obese. Prescribed lifestyle modification is a missing opportunity in implementing sustainable strategies to reduce chronic condition burden.
