Relationship of serum brain-derived neurotrophic factor (BDNF) and health-related lifestyle in healthy human subjects

The associations between serum brain-derived neurotrophic factor (BDNF) levels and several health-related lifestyle factors were evaluated in 85 healthy human subjects. Results showed that the frequency of fruit intake, exercise and television watching were associated with serum BDNF level. There was a higher serum BDNF level from the group with fruit intake five to six times per week. Subjects with moderate frequency of exercise (1–30 times of 30min exercise per month) showed higher serum BDNF level than the group with exercise more than 30 times per month. There was a significant positive correlation between serum BDNF and the daily average watching television time in the younger age group (18–35). The result of this study supports the need for larger studies with different health-related lifestyle in healthy subjects or subjects with disorders.
