Objective: To determine the prevalence and correlates of elevated blood pressure (BP) in youth with type 1 or type 2 diabetes mellitus by using data from the SEARCH Study.
Study design: The analysis included youth aged 3 to 17 years with type 1 (n = 3691) and type 2 diabetes mellitus (n = 410) who attended a research visit. Elevated BP was defined as systolic or diastolic values >or=95 percentile, regardless of drug use. In youth with elevated BP, awareness was defined as self-report of an earlier diagnosis. Control was defined as BP values <90th percentile and <120/90 mm Hg in youth with an earlier diagnosis who were taking BP medications.
Results: The prevalence of elevated BP in youth with type 1 diabetes mellitus was 5.9%; minority ethnic groups, obese adolescents, and youth with poor glycemic control were disproportionately affected. In contrast, 23.7% of adolescents with type 2 diabetes mellitus had elevated BP (P < .0001), Similarly, 31.9% of youth with type 2 diabetes mellitus and elevated BP were aware, compared with only 7.4% of youth with type 1 diabetes mellitus (P < .0001). Once BP was diagnosed and treated, control was similar in type 1 (57.1%) and type 2 diabetes mellitus (40.6%).
Conclusions: Our findings identify high-risk groups of youth with diabetes mellitus at which screening and treatment efforts should be directed.
