Use of Complementary and Alternative Medicine Among Patients With Diabetes Mellitus: A Cross-Sectional Study

Background Diabetes mellitus is one of the causes to use complementary and alternative medicine (CAM), which can be classified into nutritional, psychological and physical. The study's objective was to estimate the prevalence and pattern of using CAM among patients with diabetes mellitus who followed the endocrine and diabetes center in Taif. Materials and methods A cross-sectional study was carried out in Taif city from 1 June to 31 July 2023 among diabetic patients aged 14 years and above who followed the endocrine and diabetes center. A valid, reliable, English questionnaire was used in data collection. It was composed of three parts: demographic data, diabetes mellitus history and use of CAM. Patients visited the diabetic center during the study period for their regular appointments were selected randomly and interviewed by trained interns and medical students. By using the Raosoft calculator, the minimal sample size was 361. The chi-square test and independent two-sample t-test were used to investigate the association between categorical variables and continuous numerical variables, respectively. Multivariate logistic regression analysis was performed to control the confounding effect. Results A total of 361 patients were included. Their age ranged between 14 and 84 (51.2 ± 16.9 years). Females represented 57.6% of them. Overall, more than a quarter (28.3%) reported using CAM, while 22.4% used CAM for treating diabetes in the last 12 months. The majority of patients (97.1%) used herbs, mainly cinnamon (48.5%), fenugreek/helba (31.3%) and rosemary (20.2%). Their main source of information was family and friends (64.7%). A history of improvement of blood sugar reading with CAM was reported by 61.8%. Multivariate logistic regression analysis revealed that females were at doubled likelihood to use CAM compared to males (Adjusted odds ratio "AOR" = 2.40; 95% confidence interval "CI": 1.27-4.52, p=0.007). Compared to never-smokers, ex-smokers were more likely to use CAM (AOR=2.87; 95% CI: 1.28-6.43, p=0.010). Conclusion The use of CAM, particularly herbs, to treat diabetes is a relatively common practice among Saudi patients. However, the history of informing treating physicians about CAM was reported by a minority of patients.
