When elevated serum ALT levels were combined with abdominal obesity or obesity, we found that shorter telomere length was associated with presumed NAFLD in Mexican-American men (OR 0.15, 95% CI 0.03–0.64 for abdominal obesity; OR 0.012, 95% CI 0.0006–0.24 for obesity) (Table 2; models 4 and 5). This evidence concerns the gene GPT and Obesity.
