Chronic diseases among the studied patients.

Background
Herbal supplements (HSs) are used to treat a variety of diseases and ailments. Individuals with chronic diseases are at a higher risk of having adverse events and drug interactions from the use of HSs.
Aim
This study determined the beliefs, awareness, use, and factors associated with HSs usage among patients with chronic diseases in Alkharj, Saudi Arabia.
Method
A cross-sectional study was conducted among patients with chronic diseases between February and June 2019. Face-to-face interviews were conducted at various out-patient clinics in different hospitals. Patients diagnosed with chronic diseases were included in the study. Data were analyzed by descriptive, comparative, and inferential statistics using SAS ver. 9.4.
Results
The study participants were consisted of 533 patients, with mean age 53.6 ±12.9 years. The most prevalent chronic diseases were diabetes mellitus (67.7%), followed by hypertension (54.8%), and hyperlipidemia (53.8%). Among the studied participants, 336 (63%) had used at least one HS, whereby the most commonly used HSs were ginger (74.7%), mint (72%), and cumin (66.7%). Almost 78% of HSs users did not consult any healthcare provider about their use. HSs use varied significantly between female and male participants (p<0.05), whereby 61.5% of female participants used HSs in comparison to the male participants (38.5%). Gender (AOR 0.328; 95% CI 0.139–0.772; p = 0.0107), number of chronic diseases (AOR 1.585; 95% CI 1.084–2.318; p = 0.0312), and hyperlipidemia (AOR 2.818; 95% CI 1.507–5.269; p = 0.0.0012) were the pure factors of HSs use among the studied patients.
Conclusion
The results of this study showed that HSs usage was high among patients with chronic diseases in Saudi Arabia. Concurrent usage of HSs with drugs should be well-discussed with healthcare providers to avoid potential adverse events or drug interactions especially among patients with chronic diseases.
