Prevalence of Testing for Diabetes Among US Adults With Overweight or Obesity, 2016-2019
PREVENTING CHRONIC DISEASE(2023)
摘要
Introduction Screening for prediabetes and type 2 diabetes may allow earlier detection, diagnosis, and treatment. The US Preventive Services Task Force recommends screening every 3 years for abnormal blood glucose among adults aged 40 to 70 years with overweight or obesity. Using IQVIA Ambulatory Electronic Medical Records, we estimated the proportion of adults aged 40 to 70 years with overweight or obesity who received blood glucose testing within 3 years from baseline in 2016.Methods We identified 1,338,509 adults aged 40 to 70 years with over-weight or obesity in 2016 and without pre-existing diabetes. We included adults whose records were present in the data set for at least 2 years before their index body mass index (BMI) in 2016 and 3 years after the index BMI (2017-2019), during which we examined the occurrence of blood glucose testing. We calculated the unadjusted and adjusted prevalence of receiving blood glucose testing.Results The unadjusted prevalence of receiving blood glucose testing was 33.4% when it was defined as having a hemoglobin A1c or fasting plasma glucose measure. The unadjusted prevalence was 74.3% when we expanded the definition of testing to include random plasma glucose and unspecified glucose measures. Adults with obesity were more likely to receive the test than those with over-weight. Men (vs women) and adults aged 50 to 59 years (vs other age groups) had higher testing rates.Conclusion Our findings could inform clinical and public health promotion efforts to improve screening for blood glucose levels among adults with overweight or obesity.
