This study aimed to elucidate the associations between physical activity, sedentary behaviors, and Epstein-Barr virus (EBV) antibody levels (as an indirect marker of cell-mediated immunity, CMI). This study made use of a 14-year longitudinal study with a representative sample of adolescents in the US. A total of 3361 participants (42.1% male) aged 11 to 21years at baseline who completed Wave I (1994-1995), Wave III (2001-2002), and Wave IV (2008) surveys of the National Longitudinal Study of Adolescent Health (Add Health) were analyzed. Physical activity and sedentary behaviors at Waves I and III were assessed using interviewer-administered questionnaire. EBV viral capsid antigen (VCA) IgG antibody levels at Wave IV were analyzed from dried blood spot assays. Adjusted for confounders, among males, one additional day spent per week on strenuous sports at Wave III were associated with a decrease of 4.09AU/ml in EBV antibody levels (p=0.012), while one additional hour spent per week viewing videos at Wave I was associated with an increase of 0.83AU/ml in EBV antibody levels (p=0.026). Among females, one additional day spent per week on individual sports at Wave III were associated with a decrease of 4.63AU/ml in EBV antibody levels (p=0.014), while sedentary behaviors were not associated with EBV antibody levels. To conclude, physical activity and sedentary behaviors were associated with CMI among males and physical activity was associated with CMI among females.

生理学与行为学旨在研究行为的因果生理机制及其受环境因素的调节。该杂志邀请行为和认知神经科学广泛领域的原创报告，其中至少一个变量是生理的，主要的重点和理论背景是行为的。学科范围包括行为神经内分泌学、心理神经免疫学、学习和记忆、摄食、社会行为以及与精神病理学机制相关的研究。欢迎当代评论和理论文章，编辑邀请感兴趣的作者提出此类建议。

The journal "Physiology and Behavior" aims to investigate the physiological mechanisms underlying behavior and how these mechanisms are influenced by environmental factors. It invites original research reports from the broad fields of behavioral and cognitive neuroscience, requiring that at least one variable is physiological, with a primary focus on the theoretical background of behavior. The scope includes behavioral neuroendocrinology, psychoneuroimmunology, learning and memory, feeding, social behavior, and research related to the mechanisms of psychopathology. Contemporary reviews and theoretical articles are also welcome, and editors invite interested authors to submit such proposals.
