AIM: The present study aimed to examine the association between caffeine intake and glycemic control as measured by HbA1c levels among adolescents with type 1 diabetes mellitus.
METHOD: A cross-sectional study of eligible 96 adolescents aged between 13 to 18 years old with type 1 diabetes mellitus from three governmental hospitals and one university hospital in Jordan. Descriptive analysis was done to describe sample characteristics as well as using correlation to find the relationship between caffeine intake and glycemic control.
RESULTS: The mean age of adolescents was 14.7 years old. 95.8% used the subcutaneous insulin injection method and only 4.2% used an insulin pump. 84.4% of adolescents were diagnosed with type 1 diabetes mellitus for more than one year. The mean HbA1c level was 9.3%. Study results showed that the mean daily caffeine intake was 286.7 mg which was associated with glycemic control as measured by HbA1c level.
CONCLUSION: Modifying the amount of daily caffeine intake may be a proper target to get better glycemic control, especially among adolescents with type 1 diabetes mellitus.
