Figure 2. Prevalence of diabetes according to FHD and categories of BMI.

FHD(+) participants had a higher prevalence of diabetes than FHD(−) participants in each BMI category. Prevalence increased sharply with increases in BMI. Diabetes was considered according to HbA1c ≥6.5% and/or current medication for diabetes. FHD(+) was defined as having a first-degree relative(s) with diabetes. BMI = body mass index; FHD = family history of diabetes; HbA1c = glycated hemoglobin.
