| Research Abstract |
Serotonin transporter (5HTTLPR), COMT Val158Met and BDNF Val66Met polymorphisms were determined using blood samples from approximately 5,000 individuals in a Japanese general population. Among 5HTTLPR SS groups which has been reported to be related to depression, frequency of forest walking was inverse associated with poor mental health. This study suggested that high frequent forest walking contribute the promotion of daily mental health even if participants might have risk alleles. However, the study could not identify a causal relationship because it was a cross-sectional study. Cohort studies or intervention studies will be required to confirm this association.
