Background: It's been proved that daily activity increases insulin sensitivity, general health, and risk profiles of cardiovascular disease. Therefore; physical activities help to reduce the effects of diabetes on the human body.Unfortunately, the physical level is low among diabetic patients and this might be due to a lack of understanding about the value of exercise. The object of this paper is to assess knowledge and awareness of daily activity importance among diabetic patients in KSA. Methods: The observational study was done in KSA. A total of 380 diabetic patients are included in the study, all of whom live in Saudi Arabia. All the patients were answering a questionnaire that assesses their knowledge about the importance of physical activities.Eventually, data was analyzed by SPSS to identify their knowledge level. Results: There were 380 participants in the investigation, with 60.5% of them being female. The participants' ages varied from 18 to 76 years old, making up 43.7% of the sample. There was a 62.2% average knowledge score. The knowledge of physical activity was significantly associated with the type of diabetes, family history of diabetes, having dyslipidaemia, and having kidney disease. Conclusion: In this investigation, we discovered that the sampled people with diabetes had rather low levels of knowledge about physical exercise. More people with T1DM, those with favourable disease history, and people without dyslipidaemia or renal disease were shown to have better knowledge.
