ABSTRACT
Objective To determine the relationship between abnormal blood glucose and lipid levels and body mass index in patients with chronic respiratory diseases. Methods This research was conducted in Urumqi baseline survey population from "Xinjiang multi-ethnic cohort study" in which patients with chronic bronchitis, emphysema and chronic obstructive pulmonary disease (COPD) were screened.The patients were defined as angular, normal, overweight, obesity groups according to body mass index (BMI), and were compared with blood levels of lipid and glucose, and rate of abnormal metabolism. Results A total of 6 046 subjects were included in the 2018 Urumqi cohort study, including 545 patients with chronic respiratory diseases.The prevalence of chronic respiratory diseases in different age groups and at different physical activity levels was different, and the prevalence of emaciation group was significantly higher than that of the other three groups.However, there were no statistically significant differences among people with different genders, nationalities, educational levels and whether they smoked or not.There were statistically significant differences in fasting glucose, serum cholesterol (TC) and serum high-density lipoprotein (HDL) levels among respiratory patients with different BMI (P < 0.05).The detection rates of hyperglycemia, high TG and low HDL increased with the increase of BMI.The result of multi-factor analysis showed that blood glucose, TG and HDL were the influencing factors of BMI. Conclusion Increase of body mass index in patients with chronic respiratory diseases is associated with abnormal glucose and lipid metabolism, which is not significantly different from that in patients with non-respiratory diseases.However, the body mass index and nutritional status of patients with long-term diseases should be closely monitored, and timely intervention measures should be taken to delay the disease process.
