Abstract
Objective: This study aimed to characterize the sociodemographic and clinical profiles of Portuguese patients with type 2 diabetes mellitus (T2DM) and to assess their self-care practices, treatment adherence, motivation, and satisfaction with social support. Methods: A cross-sectional observational study was conducted at an endocrinology unit in northern Portugal from January 2021 to December 2022. The sample included 303 adult patients with T2DM who provided informed consent. Data were collected using a structured questionnaire addressing sociodemographic, clinical, and self-care aspects. Validated scales were used to assess diabetes knowledge, self-care activities, treatment adherence, motivation, and social support. Results: Of the 303 patients enrolled, with a median age of 67 years, 51.2% were female and 68.2% retired. Clinical measures showed a median systolic blood pressure of 135 mmHg, abdominal circumference of 104.6 cm, and BMI of 29.3 kg/m(2). Self-care practices were suboptimal, with only 25.1% of patients consistently following a healthy diet, and 31% engaged in weekly physical activity. Although treatment adherence was generally high, issues like forgetfulness were reported. Satisfaction with social support varied, with 30% of patients feeling isolated. Conclusions: The study identifies significant gaps in diet and physical activity adherence among T2DM patients. There is a need for targeted educational interventions and enhanced support systems to improve self-care and treatment outcomes. Personalized care strategies addressing educational, motivational, and social support factors are crucial to better managing T2DM and improving patient well-being.
