The prevalence of the metabolic associated fatty liver disease among residents aged 30 to 79 in Dongguan City of Guangdong Province
-
摘要:
目的 了解广东省东莞市30~79岁居民代谢相关脂肪性肝病(metabolic associated fatty liver disease, MAFLD) 的患病情况,探讨不同人群特征对MAFLD患病的影响。 方法 利用华南区域自然人群慢性病前瞻性队列研究在广东省东莞市的基线调查数据,包括体格检查、腹部超声检查和临床检验,共纳入8 670名研究对象。参考国际专家小组共识声明判断MAFLD患病情况。采用多因素Logistic回归分析模型分析男、女性MAFLD患病的影响因素。 结果 东莞市30~79岁居民MAFLD患病率为31.85%。男性各年龄段MAFLD患病率的差异无统计学意义(χ2 =2.958, P=0.565),女性患病率随年龄的增加而呈线性增长的趋势(χ趋势2=81.429, P<0.001)。MAFLD患病率随BMI、FPG、ALT、TG、TC、血尿酸(uric acid, UA)等代谢指标的升高而升高,随HDL-C的升高而降低。多因素Logistic回归分析模型结果显示年龄≥50岁的女性患MAFLD风险较高(OR=2.37, 95% CI: 1.74~3.23, P<0.001)。 结论 东莞市30~79岁居民MAFLD患病率为31.85%,与BMI、FPG、TG、TC等代谢指标之间呈线性关联。年龄≥50岁可能是女性患MAFLD的危险因素。 Abstract:Objective To explore the prevalence of metabolic associated fatty liver disease (MAFLD) and the impact of different characteristics among residents aged 30 to 79 in Dongguan City of Guangdong Province. Methods Baseline data were collected in Dongguan City, Guangdong Province of South China Cohort, including physical examination, ultrasound, and laboratory tests. According to the inclusion and exclusion criteria, we included 8 670 participants and defined the status of MAFLD referred to the consensus statement of international experts. Multivariate Logistic regression analysis model was used to analyze the factors according to gender. Results The prevalence of MAFLD was 31.85% among residents aged 30 to 79 in Dongguan City. The prevalence was similar among males in different age groups (χ2 =2.958, P=0.565), while it linearly increased with age in females (χtrend2=81.429, P < 0.001). The prevalence showed a linear increase with BMI, FPG, ALT, TG, TC, uric acid (UA) while a linear decrease with HDL-C. The results of multivariate Logistic regression analysis model showed that females ≥50 years old had a higher risk of MAFLD (OR=2.37, 95% CI: 1.74~3.23, P < 0.001). Conclusions The prevalence of MAFLD was 31.85% among residents aged 30 to 79 in Dongguan City, and there was a linear association between the prevalence of MAFLD and various metabolic indices including BMI, FPG, TG, and TC. Age ≥50 years old may be a risk factor of MAFLD in females. -
