61-LB: Blood Pressure and Lipid-Lowering Medication Adherence in Young Adults with Youth-Onset Type 2 Diabetes and Hypertension or Dyslipidemia—The TODAY2 iCount Study

Abstract

Youth-onset type 2 diabetes (T2D) is associated with early development of vascular complications. Treatment of hypertension and dyslipidemia are critical to reduce morbidity. iCount examined adherence to blood pressure (BP) and lipid-lowering medications in young adults with youth-onset T2D (mean age 26 y, duration of T2D 12 y, BMI 37 kg/m2) and hypertension/nephropathy (n=196) or dyslipidemia (n=146) during the observational phase of the Treatment Options for type 2 Diabetes in Adolescents and Youth (TODAY)2 study (2017-2019). They were receiving diabetes care in their communities. Adherence was assessed with 3 monthly unannounced phone pill counts at 2 times 1 year apart. Percent low adherent (<80% pill-taking) and high-adherent (≥80% pill-taking) did not change over time. Of participants with hypertension and/or nephropathy, 80.1% were low adherent, 19.9% were high adherent. Those who were low adherent had fewer years of education (p=0.004), higher HbA1c (p=0.001) and shorter diabetes duration (p=0.031). Of those with dyslipidemia, 93.8% were low adherent, 6.2% high adherent. Those low adherent to BP (p<0.001) and lipid-lowering (p≤0.008) medications were also low adherent to oral hypoglycemic medications or insulin. Beliefs that medications are necessary were lower for those low adherent to BP and lipid-lowering medications (unadjusted analyses); concerns about medications also were lower for those low adherent to lipid-lowering medications. In adjusted multivariable analyses of participants with hypertension or nephropathy, having ≥1 material need insecurity predicted medication adherence 1 year later (p=0.010). Belief about medicines, diabetes distress, self-efficacy, depressive and anxiety symptoms, and self-management support were not 1 yr predictors of medication adherence. To prevent early vascular events, approaches that further identify and address unmet needs should be studied. Disclosure P. M. Trief: None. R. S.
