The relationship between depression and the Val66Met polymorphism at the brain-derived
neurotrophic factor gene (BDNF), has been largely studied. It has also been related to physical activity,
although the results remain inconclusive. The aim of this study is to investigate the relationship
between this polymorphism, depression and physical activity in a thoroughly characterised sample of
community-based individuals from the PISMA-ep study. A total of 3123 participants from the PISMAep
study were genotyped for the BDNF Val66Met polymorphism, of which 209 had depression.
Our results are in line with previous studies reporting a protective effect of physical activity on
depression, specifically in light intensity. Interestingly, we report a gene-environment interaction
effect in which Met allele carriers of the BDNF Val66Met polymorphism who reported more hours
of physical activity showed a decreased prevalence of depression. This effect was observed in the
total sample (OR = 0.95, 95%CI = 0.90–0.99, p = 0.027) and was strengthened in women (OR = 0.93,
95%CI = 0.87–0.98, p = 0.019). These results highlight the potential role of physical activity as a
promising therapeutic strategy for preventing and adjuvant treatment of depression and suggest
molecular and genetic particularities of depression between sexes.
