Watching television and playing video game being seated represent sedentary behaviours and increase the risk of weight gain and hypertension. We investigated the acute effects of violent and non-violent video-game playing on blood pressure (BP), appetite perception and food preferences. Forty-eight young, normal-weight men (age: 23.1±1.9 years; body mass index: 22.5±1.9 kg/m(2)) participated in a three-arm, randomized trial. Subjects played a violent video game, a competitive, non-violent video game or watched TV for 1 h. Measurements of BP, stress and appetite perception were recorded before a standardized meal (∼300 kcal) and then repeated every 15 min throughout the intervention. Violent video-game playing was associated with a significant increase in diastolic BP (Δ±s.d.=+7.5±5.8 mm Hg; P=0.04) compared with the other two groups. Subjects playing violent video games felt less full (P=0.02) and reported a tendency towards sweet food consumption. Video games involving violence appear to be associated with significant effects on BP and appetite perceptions compared with non-violent gaming or watching TV.
看电视和玩电子游戏都是久坐行为，会增加体重增加和高血压的风险。我们研究了玩暴力和非暴力电子游戏对血压（BP）、食欲感知和食物偏好的急性影响。48 名年轻、体重正常的男性（年龄：23.1±1.9 岁；体重指数：22.5±1.9kg/m(2)) 参加了一项三臂、随机试验。受试者玩了 1 小时的暴力电子游戏、竞争性非暴力电子游戏或看电视。在标准化餐（约 300 卡路里）前记录血压、压力和食欲感知测量值，然后在干预过程中每 15 分钟重复一次。与其他两组相比，玩暴力电子游戏时舒张压（Δ±s.d.=+7.5±5.8mm Hg；P=0.04）显著升高。玩暴力电子游戏的受试者感觉不太饱（P=0.02），并表示倾向于吃甜食。与非暴力游戏或看电视相比，涉及暴力的电子游戏似乎会对血压和食欲感知产生重大影响。
