[Analysis of Influencing Factors of Hyperuricemia in Tibetan Population in Nagqu City, Tibet].

Objective: To analyze the prevalence of hyperuricemia (HUA) among the Tibetan population in Nagqu City, Tibet and to uncover the relevant influencing factors.
Methods: From July 2020 to August 2021, 763 Tibetan natives from Bangor County (specifically Xinji Township and Jiaqiong Township) and Seni District (specificially Sexiong Township), Nagqu City were investigated by multi-stage cluster random sampling method and the prevalence of HUA was studied by retrospective analysis. Chi-square test and multiple logistic regression were used to analyze the influencing factors of HUA prevalence.
Results: The overall prevalence of HUA among the Tibetan population in the three townships of Nagqu City was 19.66% (150/763). In particular, the prevalence in men was 35.00%, while that in women was 8.58%, showing significant difference ( P <0.05). According to the results of univariate analysis, there were significant differences in the distribution of sex, abnormal liver function, abnormal hemoglobin, hyperlipidemia, high level of low-density lipoprotein, hypertriglyceridemia, hypercholesterolemia, abnormal creatinine, hyperhomocysteinemia, obesity, and hypertension between HUA and non-HUA patients ( P <0.05). Multiple logistic regression showed that female sex (odds ratio [ OR ]=0.195, 95% confidence interval [ CI ]: 0.120-0.315) was a protective factor for HUA, while abnormal liver function ( OR =2.812, 95% CI : 1.685-4.692), abnormal creatinine ( OR =7.374, 95% CI : 1.446-37.620), high level of low-density lipoprotein ( OR =2.357, 95% CI : 1.011-5.492), and hyperlipidemia ( OR =3.056, 95% CI : 1.886-4.951) were independent risk factors.
Conclusion: The prevalence of HUA is relatively high in Nagqu city and the prevalence of HUA is much higher in men than that in women. Male sex, abnormal liver function, abnormal creatinine, elevated low-density lipoprotein, and hyperlipidemia may be the risk factors for HUA in the local Tibetan population.
