The Relationship between the Serum Aspartate Aminotransferase/Alanine Aminotransferase Ratio and Pulse Pressure in Korean Adults with Hypertension

The Relationship between the Lipid Accumulation Product and Beta-cell Function in Korean Adults with or without Type 2 Diabetes Mellitus: The 2015 Korea National Health and Nutrition Examination Survey

AIMS

This study was conducted to assess the relationship between the lipid accumulation product index (LAP) and the homeostasis model assessment for insulin resistance (HOMA-IR) and beta-cell function (HOMA-B) in Korean adults with or without type 2 diabetes mellitus (T2DM).

MATERIALS AND METHODS

The study was carried out using data from the 2015 Korean National Health and Nutrition Examination Survey (KNHANES) and included 4,922 adults aged 20 or older.

RESULTS

There were several key findings. First, in overall population, after adjusting for related variables, HOMA-IR (p < .001) and HOMA-B (p < .001) level were positively associated with quartiles of LAP. Second, in non-T2DM group, HOMA-IR (p < .001) and HOMA-B level (p < .001) were positively associated with quartiles of LAP. Third, in T2DM group, HOMA-IR (p < .001) level was positively associated with the quartiles of LAP, but HOMA-B (p = .153) level was not significant. In addition, HOMA-B level was increased with an increasing metabolic syndrome component in non-T2DM (p < .001) but not in T2DM (p = .267).

CONCLUSIONS

LAP was positively associated with both HOMA-IR and HOMA-B in non-diabetic Korean adults. However, LAP was positively associated with HOMA-IR in Korean adults with T2DM, while the association with HOMA-B was not significant.
