Objective: To investigate the trends in incidence and mortality of thyroid cancer in cancer registration areas of Xinjiang Uygur Autonomous Region from 2016 to 2020 and its epidemiological status in 2020, so as to provide the basis for improving prevention and control measures for thyroid cancer. Methods: The data of thyroid cancer incidence and mortality from 2016 to 2020 in four cancer registration areas of Xinjiang Uygur Autonomous Region were collected through the Tumor Registry. The crude incidence and crude mortality were calculated. The Chinese population-standardized rate and world population-standardized rate were calculated using the age structure of the standard population from the Fifth National Population Census in 2000 and Segi's world standard population. The incidence and mortality characteristics of thyroid cancer in different genders and ages in 2020 were described. The trends in the Chinese population-standardized incidence and mortality of thyroid cancer in Xinjiang Uygur Autonomous from 2016 to 2020 were assessed using the average annual percent change (AAPC). Results: In 2020, the crude, Chinese population-standardized and world population-standardized incidences of thyroid cancer in Xinjiang Uygur Autonomous Region were 32.91/100 000, 26.99/100 000, and 25.53/100 000, respectively. The crude, Chinese population-standardized and world population-standardized mortalities of thyroid cancer were 1.25/100 000, 0.96/100 000, and 0.98/100 000, respectively. The Chinese population-standardized incidence and mortality of thyroid cancer in females were 2.44 times and 2.20 times those in males, respectively. The crude incidence of thyroid cancer was increased after age of twenty years, with a peak at age of 55 to 60 years (76.73/100 000) before rapidly declining. In contrast, the crude mortality remained low across all age groups, with the highest rate observed at age of 70 to 75 years (13.70/100 000). From 2016 to 2020, the Chinese population-standardized incidence and mortality of thyroid cancer showed no significant changes (both P>0.05). Conclusions From 2016 to 2020, the trends in incidence and mortality of thyroid cancer in cancer registration areas of Xinjiang Uygur Autonomous Region were stable. The disease burden of thyroid cancer was higher in females than in males. The crude incidence first rised and then declined with age, peaks at age of 55-<60 years.

Objective: To investigate the prevalence and influencing factors of hyperuricemia among adults in Xinjiang Uygur Autonomous Region, so as to provide insights into the prevention and intervention of hyperuricemia. Methods: Permanent residents at ages of 18 years and above in 8 counties (cities, districts) of Xinjiang Uygur Autonomous Region were sampled using a multi-stage cluster random sampling method from July 2018 to November. Demographic data, smoking, alcohol consumption, body mass index and serum uric acid were collected through questionnaire surveys, physical examination and laboratory testing. Factors affecting hyperuricemia were analyzed using a multivariable logistic regression model. Results: A total of 4 690 residents were collected, including 2 093 males (44.63%) and 2 597 females (55.37%), and had a mean age of (49.45±14.57) years. There were 1 795 overweight residents (38.27%), 1 198 residents with obesity (25.54%), 983 smokers (20.96%), 1 224 drinkers (26.10%), and 268 residents with hyperuricemia (5.71%). Multivariable logistic regression analysis showed that a higher risk of hyperuricemia was seen among adults who were males (OR=1.409, 95%CI: 1.036-1.917), aged 60 years and above (OR=2.092, 95%CI: 1.495-2.928), had high school education or above (high school, OR=2.003, 95%CI: 1.366-2.937; college and above, OR=4.876, 95%CI: 3.196-7.438), were overweight (OR=2.343, 95%CI: 1.618-3.395) or obese (OR=4.754, 95%CI: 3.291-6.868) and had alcohol consumption (OR=1.494, 95%CI: 1.104-2.020). Conclusion The risk of hyperuricemia may be associated to gender, age, educational level, body mass index and alcohol consumption among adults in Xinjiang Uygur Autonomous Region.
