Abstract

To test the relationship not yet explored before among earthquake and related environmental factors, low-density lipoprotein receptor (LDLR) and posttraumatic stress disorder (PTSD), the genetic variation of LDLR rs5925 was selected and PTSD was examined by PTSD Checklist-Civilian Version (PCLC) in adolescents with different genotypes of LDLR rs5925 longitudinally at 6, 12 and 18 months after the 2008 Wenchuan earthquake. The C allele carriers were observed to have higher PTSD prevalence than the TT homozygotes in the male subjects, and higher PTSD prevalence and PCL-C scores in the female subjects only at 6 months. When compared to that at 12 months, decreased PTSD prevalence was observed at 18 months only in the female C allele carriers, but not in the female TT homozygotes or the male subjects. The potential risk factors of PTSD and predictors of PCL-C scores were different during the follow-up. LDLR rs5925 was one of the predictors for PCL-C scores at 6 and 12 months, and one of the potential factors for PTSD prevalence at 6 months. These results suggest that interactions may occur between earthquakes and other related environmental factors, which could affect the relationship of LDLR rs5925 with PTSD and be considered for individualized treatment.
