Objective: The objective of this study was to investigate the effects of the interaction between lipoprotein lipase (LPL) PvuII and HindIII haplotypes and carbohydrate intakes on the components of metabolic syndrome (MetSyn) in Koreans. Methods: LPL PvuII and HindIII genotype, LPL mass, triglyceride, high-density lipoprotein cholesterol, blood pressure (BP), waist circumference (WC), insulin, and Homeostasis Model of Assessment - Insulin Resistance were determined using a cross-sectional design in 269 controls and 280 MetSyn patients. Results: LPL mass was significantly lower in patients with PvuII and HindIII mutant alleles (P2 and H2) and decreased as the number of MetSyn components increased in all PvuII and HindIII haplotypes. Both LPL mass-adjusted WC and systolic BP (SBP) were positively associated with a ratio of percent energy from carbohydrate to percent energy from fat in individuals with P2H2 haplotype. After adjustment for age, sex, and LPL mass, the odds ratio (OR) for excessive WC was higher in carriers of P2H2 in the highest carbohydrate intake tertile compared with carriers of P1H1 in the lowest carbohydrate intake tertile (OR, 6.94; 95% confidence interval [CI], 1.39-34.62). Moreover, the OR for high SBP were higher in carriers of P1H2/P2H1 in the highest carbohydrate intake tertile (OR, 7.84; 95% CI, 1.79-34.46) and in carriers of P2H2 in the highest carbohydrate intake tertile (OR, 4.24; 95% CI, 1.16-15.48) than P1H1 carriers. Conclusion: This study suggests that P2H2 carriers in the highest carbohydrate intake tertile may be at risk for MetSyn because they had increased odds of excessive WC and high SBP.
