| Abstract: | The association between hypertension and nonalcoholic fatty liver disease (NAFLD) is not completely understood. This study aimed to investigate the association between hypertension and hepatic ultrasound examination-diagnosed positive NAFLD in healthy people; to conduct a comprehensive meta-analysis combining the results of previous studies; to explore whether hypertension was a risk factor for NAFLD. This study included 2049 adults (male: 870 and female: 1179), aged ≥20 years, whose anthropometric parameters were measured to analyze the risk of hypertension on NAFLD. We also collected data from 11 cross-sectional studies relevant to this topic using PubMed, Embase, Web of Science, CNKI, Wanfang, and CQVIP from beginning till 31 August 2020 and combined it with our data for a meta-analysis to explore whether hypertension was a risk factor for NAFLD. After adjusting for confounding factors, the odds of NAFLD in hypertensive subjects was 1.473 (95%CI: 1.119-1.938). After combining with 10 selected studies, 42711 participants were enrolled in meta-analysis. Hypertension was a risk factor for NAFLD (Z = 13.46, P < 0.001); the odds of NAFLD in hypertensive subjects was 1.43 (95%CI: 1.36-1.51). The results were consistent with the results of the meta-analysis. Further studies are required to confirm these results. |
