OBJECTIVE
One explanation for the relationship between TV viewing and obesity is that people may (over)eat while watching TV. The current study investigated associations between TV viewing and the time spent on (concurrent) eating in a naturalistic setting among a general population sample.
DESIGN
Preregistered secondary data analyses were performed of a diary survey in which respondents reported their time use in 10-min blocks for 7 d.
SETTING
Concurrent TV viewing and eating was operationalised as all blocks in which TV viewing and eating occurred simultaneously. Furthermore, the TV content respondents watched was coded as food-related (i.e. culinary content) or non-food related.
PARTICIPANTS
The sample composed of 2292 adults (58·9 % female) in the Netherlands, aged ≥ 20 years, from all educational levels (18·1 % low, 29·8 % middle and 51·4 % high).
RESULTS
More than half of the respondents (51·3 %) reported concurrent TV viewing and eating at least once during the 7-d diary period. The average eating occasion was longer in duration while watching TV (. without media use), and the total time spent on eating was longer on days of concurrent TV viewing and eating (. days of eating without media use). The percentage of TV viewing time spent on concurrent eating did not differ between food-related and non-food-related TV content.
CONCLUSIONS
Eating while watching TV was related to an increased time spent on eating. Even though energy intake was not assessed, these findings from a naturalistic setting provide further evidence that concurrent TV viewing and eating may contribute to overeating.
目的
看电视与肥胖之间关系的一种解释是，人们在看电视时可能会（过度）进食。本研究调查了在一般人群样本的自然环境中，看电视与同时进食所花费时间之间的关联。
设计
对一项日记调查进行预先登记的二次数据分析，受访者以10分钟为时间段报告他们7天的时间使用情况。
背景
同时看电视和进食被定义为看电视和进食同时发生的所有时间段。此外，受访者观看的电视内容被编码为与食物相关（即烹饪内容）或与食物无关。
参与者
样本包括荷兰2292名成年人（58.9%为女性），年龄≥20岁，来自所有教育水平（低水平占18.1%，中等水平占29.8%，高水平占51.4%）。
结果
超过一半的受访者（51.3%）报告在7天的日记记录期内至少有一次同时看电视和进食。看电视时平均进食时间更长（.不使用媒体时），在同时看电视和进食的日子里，进食总时间更长（.不使用媒体进食的日子）。与食物相关和与食物无关的电视内容在同时进食所花费的看电视时间百分比上没有差异。
结论
边看电视边进食与进食时间增加有关。尽管未评估能量摄入，但这些来自自然环境的发现进一步证明，同时看电视和进食可能导致暴饮暴食。
