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 30 min 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.
在85名健康受试者中评估了血清脑源性神经营养因子（BDNF）水平与几种与健康相关的生活方式因素之间的关联。结果显示，水果摄入频率、运动和看电视与血清BDNF水平相关。每周摄入水果5至6次的组血清BDNF水平较高。运动频率适中（每月进行30分钟运动1 - 30次）的受试者血清BDNF水平高于每月运动超过30次的组。在较年轻年龄组（18 - 35岁）中，血清BDNF与每日平均看电视时间之间存在显著正相关。本研究结果支持在健康受试者或患有疾病的受试者中开展针对不同与健康相关生活方式的更大规模研究的必要性。
