Differential effects of gender and patient background diversity on the changes in metabolic and biophysical profiles in people with type-2 diabetes from different ethnicities who fast during Ramadan (H1439); a prospective study from Qatar

Objective: The 'PROspective Study of dose adjustment of multiple anti-diabetic therapy for Type-2 diabetic patients FASTing the Month of Ramadan aimed to assess the biophysical and metabolic effects of fasting during Ramadan, including HbA1c, weight, blood pressure and lipid profile. Study design methods: We performed a prospective study of people with Type-2 diabetes who were on >= 3 drugs for lowering glucose before and after Ramadan of H1438 (May-June 2017) in Hamad Medical Corporation, Qatar. We enrolled 228 participants, of whom 181 completed the study and were included in the analysis. Results: There were 115 (63.5%) men and 66 (36.5%) women, mean age 53.6 +/- 9.7 years and mean diabetes duration of 10 +/- 6 years. Both HBA1c [7.8% (62 mmol/mol) vs. 7.6% (60 mmol/mol); p = 0.004]; and diastolic BP (75.7 +/- 8.55 vs. 68.8 +/- 23.1 mmHg, P = 0.001) improved significantly after Ramadan while there was an increase in total cholesterol (3.94 +/- 0.89 mmol/l vs 4.11 +/- 1.02 mmol/l; p = 0.008) and triglycerides (1.55 +/- 0.72 mmol/l vs 1.71 +/- 0.9 mmol/l; p = 0.012). Subgroup analysis showed that patients on sulphonylurea, South Asians and males had a significant reduction in both HBA1c and weight. Conclusion: Patients with Type 2 diabetes who fast during Ramadan show an improvement in glycaemic control and diastolic blood pressure, but a worsening of total cholesterol and triglycerides, particularly those of South Asian origin and men.
