At present, chronic kidney disease is one of the significant problems in Thailand and worldwide. According to the research, the prevalence of chronic kidney disease in 2017 was 697.5 million people across the globe or around 9.1 percent of the world population. The prevalence increased by 29.3 percent from 1990 to 2017. In addition, the study of chronic kidney disease prevalence in Thailand in 10 provinces covering all regions in Thailand found that the prevalence of chronic kidney disease was 17.5 percent, and from the studies with people who have the criteria for chronic kidney disease in every stage, all studies indicate that hyperglycemia and blood pressure affects the development of chronic kidney disease. In a study by the American Association of Diabetes Educators in 2017, diabetes causes chronic kidney disease in 44 percent of all patients with chronic kidney disease. The study of the relationship between overweight and diabetes under the topic of the Mechanism linking diabetes mellitus and obesity 2014 found that increased BMI levels were associated with the development of insulin-resistant diabetes. Of people with type 2 diabetes, 86 percent of these people were associated with being overweight or obese, and, in addition, being overweight and obesity are global health problems. The prevalence of obesity increased dramatically in 2016; there were 1.9 billion adults (people older than 18 years old) worldwide with overweight, of which more than 650 million are obese. The research team sees the importance of chronic kidney disease, which is why the research team decide to study the prevalence and risk factors of chronic kidney disease. In addition, the relationship between overweight and the prevalence of chronic kidney disease patients in Sanam Chai Khet hospital has yet to be studied. For this reason, the research team is interested in studying the relationship between being overweight and the prevalence of chronic kidney disease in Sanam Chai Khet hospital. Therefore, a cross-sectional study investigates chronic kidney disease's prevalence and risk factors in Sanam Chai Khet hospital chronic kidney patients during 2016-2020. The data were retrieved from electronic medical records of the hospital information system. A total of 1263 chronic kidney patients participated in the study; 937 patients were diagnosed with chronic kidney stage 3 or above, a prevalence of 74.19 percent. The risk factors of chronic kidney disease stage 3 or above are patients over 70 years old, with a body mass index greater than 23 kg/m2, diabetes patients, hypertension, and hypertensive crisis.
