Hypertension (HTN) is an important cardiovascular risk factor in patients with type 1 diabetes (T1D), who are at increased risk the greater the duration and severity of HTN.1,2 For this reason, patients with T1D used to be screened for HTN by means of office blood pressure (BP) measurement, with use of ambulatory blood pressure monitoring (ABPM) to confirm the diagnosis. The most recent European Society of Hypertension guidelines for the management of high blood pressure in children and adolescents recommend ABPM in patients with a T1D diagnosis,3 although due to its lower availability it is not used routinely. The aim of our study was to describe the different BP phenotypes based on the isolated office BP measurements (clinic BP) and ABPM in children and adolescents with T1D and analyse the presence of differences in epidemiological, clinical or laboratory characteristics associated with high ambulatory BP values. We conducted a cross-sectional study in a cohort of children and adolescents with T1D followed up in the childhood diabetes unit of a tertiary care hospital. We included patients aged 5 to 18 years with T1D of more than 6 months’ duration without a prior history of HTN. The primary variables were the clinic BP and the 24-h ambulatory BP. We collected data on previous capillary glycated haemoglobin and lipid profile values as well as the body mass index (BMI) z-score relative to the reference population of the same age and sex.
