Delivery of healthcare provider’s lifestyle advice and lifestyle behavioural change in adults who were overweight or obese in pre-diabetes management in the USA: NHANES (2013–2018)

OBJECTIVE: The purpose of this study is to examine the association between delivery of healthcare provider’s advice about lifestyle management and lifestyle behavioural change in pre-diabetes management in adults who were overweight or obese. DESIGN: This cross-sectional study included adults with body mass index (BMI) ≥25 kg/m(2) and reporting pre-diabetes in USA. Outcomes included the prevalence of receiving provider’s advice on lifestyle management and patterns of practicing lifestyle change. The association between delivery of provider’s advice and lifestyle-related behavioural change in pre-diabetes management was examined. SETTING: US Continuous National Health and Nutrition Examination Survey (2013–2018). PARTICIPANTS: A total of 1039 adults with BMI ≥25 kg/m(2) reported pre-diabetes. RESULTS: Of eligible adults with pre-diabetes, 76.8% received provider’s advice about lifestyle change. The advice group showed higher proportions of ongoing lifestyle change than no advice group, including weight reduction/control (80.1% vs 70.9%, p=0.018), exercise (70.9% vs 60.9%, p=0.013) and diet modifications (83.8% vs 61.8%, p<0.001). After adjustment, those receiving provider’s advice were more likely to increase exercise (OR 1.63, 95% CI 1.12 to 2.38) and modify diet (OR 3.0, 95% CI 1.82 to 4.96). CONCLUSION: Over 75% of US adults who were overweight or obese and reported pre-diabetes received healthcare provider’s advice about reducing the risk of diabetes through lifestyle change. Provider’s advice increased the likelihood of lifestyle-related behavioural change to exercise and diet.
