Prevalence and impact of sociodemographic factors, comorbidities, and lifestyle on diabetes complications among patients with type 2 diabetes in Riyadh

Diabetes mellitus (DM) is a growing public health concern globally, particularly in Saudi Arabia, where increasing prevalence is associated with significant morbidity. This study aimed to assess the prevalence of diabetes-related complications among patients in Riyadh and examine the impact of sociodemographic factors, comorbidities, and lifestyle habits on these complications. A cross-sectional study was conducted with 980 diabetic patients attending health centers in Riyadh from March to April 2023. Data were collected via a validated bilingual questionnaire that captured sociodemographic information, diabetes-related variables, comorbid conditions, lifestyle habits, and complications. Statistical analyses, including descriptive statistics, chi-square tests, and binary regression, were performed via SPSS to identify significant associations. A p-value less than 0.05 was considered significant for all comparisons. Among the participants (980), 38% (378) reported diabetes-related complications, primarily neuropathy (30%), retinopathy (25%), and cardiovascular diseases (20%). Complications were significantly associated with older age (p < 0.001) and longer diabetes duration (more than 5 years; p < 0.001). Individuals with hypertension, hyperlipidemia, heart disease, kidney disease, and obesity had significantly higher complication rates than those without these conditions (p < 0.05). The most pronounced association was observed in participants with heart disease (85% vs. 15%; RR = 1.506), highlighting the need for better management of these comorbidities. Consuming fruits and vegetables, milk, and regular exercise were inversely associated with the risk of complications (p < 0.05). Conversely, sugary drinks, white bread, sheesha/vaping, and inadequate sleep were linked to increased risk (p < 0.05), highlighting the protective role of healthy dietary and lifestyle habits. This study highlights the impact of sociodemographic factors and lifestyle choices—such as age, education, family history, comorbidities, and poor diet—on diabetes complications. While early detection and lifestyle interventions are vital, a cautious approach is needed when applying these findings to other regions, given differences in socioeconomic circumstances.
