title: Lipid phenotypes in patients with nonalcoholic fatty liver disease.
abstract: There has been conflicting evidence regarding the role of single lipid species in the pathogenesis of nonalcoholic fatty liver disease (NAFLD). We aimed to explore the associations between dyslipidemia phenotypes (combinations of lipid parameters) and the risk of NAFLD.
  
  
  
  We conducted a cross-sectional analysis using a cohort of 9560 apparently healthy Chinese adults who underwent comprehensive health checkups including abdominal ultrasonography.
  
  
  
  Of 3709 participants with NAFLD, 41.8% were classified as normolipemia (NL), 3.8% as combined hyperlipidemia, 3.2% as hypercholesterolemia, 17.7% as dyslipidemia of metabolic syndrome (MetS), 10.2% as isolated low high-density lipoprotein cholesterol (HDL-C), and 23.3% as isolated hypertriglyceridemia. The multivariable-adjusted odds ratios (ORs) (with 95% confidence intervals) for NAFLD in those with combined hyperlipidemia, those with hypercholesterolemia, those with MetS dyslipidemia, those with low HDL-C, and those with hypertriglyceridemia compared with those with NL were 4.79 (3.19-7.20), 1.26 (0.94-1.69), 3.31 (2.74-3.99), 1.13 (0.95-1.34), and 2.63 (2.26-3.08), respectively. The associations between combined hyperlipidemia, MetS dyslipidemia, or hypertriglyceridemia and risk of NAFLD were consistently seen in various evaluated subgroups. The interactions between lipid phenotypes and sex, body mass index (BMI), blood pressure (BP), fasting plasma glucose (FPG), or uric acid (UA) were not significant for NAFLD (all P>0.05).
  
  
  
  There were diverse dyslipidemia phenotypes in patients with NAFLD. Combined hyperlipidemia, MetS dyslipidemia, and hypertriglyceridemia were strongly and independently associated with increased risk of NAFLD. Gender, BMI, BP, FPG, and UA status did not modify the associations between dyslipidemia phenotypes and NAFLD.
