[Prevalence and influencing factors of hyperuricemia among natural gas drilling workers in Northwest Sichuan gas field in 2016].

Objective: To investigate the prevalence and influencing factors of hyperuricemia among natural gas drilling workers in Northwest Sichuan gas field.

Methods: A census of 1051 natural gas drilling workers in Northwest Sichuan gas field at an average altitude of 2552 meters was conducted in the survey, the serum uric acid, fasting blood glucose, blood lipid, creatinine and hemoglobin were detected. A staff canteen was randomly selected and the method of weighing and 24-hour dietary review were used for dietary survey. The blood biochemical level and dietary intake of subjects with different blood uric acid levels were compared, and the influencing factors of hyperuricemia were analyzed by Logistic regression model.

Results: (1)There were 513 hyperuricemia patients in natural gas drilling workers, with a detection rate of 48. 8%. (2)The levels of fasting blood glucose, total cholesterol, triglyceride, creatinine and hemoglobin in the hyperuricemia group were higher than those in the normouricemia group. The risk of hyperuricemia in patients with diabetes, hypercholesterolemia, hypertriglyceridemia, elevated serum creatinine and hemoglobin were 3. 57(95%CI 2. 45-4. 67), 2. 88(95%CI 1. 99-4. 16), 1. 93(95%CI 1. 30-2. 86), 1. 61(95%CI 1. 01-2. 51)and 2. 54(95%CI 2. 11-3. 36)times of normal fasting blood glucose, blood lipid, serum creatinine and hemoglobin, respectively(P<0. 05). (3)The intakes of meat, oil and salt in the hyperuricemia group were higher than those in the normouricemia group, while the intakes of vegetables, milk products and vitamin B were lower than those in the normouricemia group(P<0. 05). Intake of vegetable is a protective factor for hyperuricemia(0. 82(95%CI 0. 65-0. 93)), and intakes of protein(1. 47(95%CI 1. 16-2. 28))and fat(2. 34(95%CI 2. 01-3. 22)) are the risk factors.

Conclusion: Drilling workers in Northwest Sichuan gas field have a high prevalence of hyperuricemia and are related to diabetes, hypercholesterolemia, hypertriglyceridemia, elevated creatinine and hemoglobin, and too much protein, fat intake and too little vegetable intake.
