Impact of Ramadan Fasting on Cardiometabolic and Inflammatory Biomarkers among Saudi Adults with Diabetes

Abstract

Background and Aims::Diabetes is prevalent in Saudi Arabia. As dietary concerns are central in patients with diabetes, the impact of fasting on health during Ramadan is potentially significant. Decreased meal frequency and changes in food type and amount affect body weight and metabolic profiles. This study aimed to investigate the association between Ramadan fasting and anthropometric measurements and cardiometabolic and inflammatory biomarkers in Saudi adults with diabetes.

Methods::Sixty-eight Saudi adults with diabetes, admitted at the University Diabetes Centre in Riyadh, Saudi Arabia, were enrolled in this study. Participants were evaluated at the following time points: six weeks before Ramadan (pre-fasting) and at least 15 days after the initiation of Ramadan (peri-fasting). Anthropometric measurements and cardiometabolic and inflammatory biomarker levels were assessed during both visits.

Results::After accounting for confounding factors, Ramadan fasting was found to be associated with reduced body weight (kg), waist circumference (cm), and hip circumference (cm). Increased log high-density lipoprotein-cholesterol and decreased log interleukin 6 and C-reactive protein levels were observed.

Conclusions::Ramadan fasting was associated with increased HDL-C levels and decreased anthropometric measurements and inflammatory cytokine levels. These results support the beneficial role of Ramadan fasting in reducing cardiometabolic abnormalities and inflammation in adults with diabetes.
