Objective: To investigate the association between glucose levels and the prevalence of headaches among the adult Saudi population.

Methods: This research will employ a cross-sectional study design, which involves collecting data from a sample of the Saudi population at a single point in time. This design allows for the investigation of the association between glucose levels and headache prevalence in a cost-effective and time-efficient manner.

Results: The study included 574 participants. The most frequent weight among them was 51-65 kg (n= 196, 34.1%), followed by 66-75 kg (n= 130, 22.6%). The most frequent height among study participants was 151-160 cm (n= 229, 39.9%), followed by 161-170 cm (n= 195, 34%). The most frequent age among study participants was less than 25 years (n= 203, 35.4%), followed by 25-30 years (n= 143, 24.9%). The most frequent nationality among study participants was Saudi (n= 547, 95.3%), followed by non-Saudi (n= 27, 4.7%). The most frequent gender among study participants was female (n= 351, 61.1%), followed by male (n= 223, 38.9%). The perceived blood sugar level intake varied among study participants, with most having normal blood sugar levels. Participants were asked if they smoked. Most were not smoking (n=482, 84%), and non-smoking were (n=92, 26%). Participants were asked about the nature of the headache. The most frequent were they don’t have (n= 345, 60.1%), followed by sharp (n= 116, 20.2%), and the least was continuous (n=113, 19.7%). Participants were asked about a kind of headache. The most frequent were they don’t have (n= 367, 63.9%), followed by stress headaches (n= 116, 20.2%), and the lowest cluster (n=15, 2.6%).

Conclusion: The results of the study showed that most of the participants were Saudis. Most of them are women. In addition, the majority of people have normal fasting blood sugar levels. Their physical activity is moderate and the majority are non-smokers. In addition, most of the study participants had good and effective social communication.
