Social Support, Treatment Adherence and Outcome among Hypertensive and Type 2 Diabetes Patients in Ambulatory Care Settings in southwestern Nigeria

Objectives: To evaluate available and desired sources and types of social-support among hypertensive and type-2- diabetes (T2D) patients. Associations of medication adherence and clinical outcome with access to most available social-support and medicine affordability were subsequently investigated.Design: Cross-sectional questionnaire-guided interview among 250-hypertensive and 200-T2D patients, and review of medical records to retrieve disease-specific clinical parameters.Settings: University College Hospital and Ring-Road State Hospital, Ibadan, southwestern Nigeria.Participants: Adults out-patients with hypertension, T2D, and T2D comorbid with hypertension were enrolled, while in-patients were excluded.Results: Family source of support was the most available [hypertensive (225; 90.0%); T2D (174; 87.0%)], but government and non-governmental organisation support were largely desired, with financial support preferred, 233(93.2%) hypertensive and 190(95.0%) T2D, respectively. Adherent hypertensive patients with or without access to family support were (127; 56.4%) versus (18; 72.0%), p=0.135; while for T2D were (103; 59.2%) versus (21;80.8%), p=0.035. Mean systolic blood pressure of hypertensive and fasting plasma glucose of T2D with access to family and financial support were better than their counterparts without access (p>0.05). Hypertensive (110; 76.4%) and T2D (87; 87.0%) participants who consistently afford medicine expenses had significantly better adherence and outcome (p
