Watching television is a common pastime for very young children. High exposure may negatively influence physical and mental health outcomes. Not much is known about how early exposure relates to lifestyle choices in adolescence.
To estimate how toddler televiewing is subsequently associated with lifestyle indicators at adolescence.
Participants are 986 girls and 999 boys from the Quebec Longitudinal Study of Child Development birth cohort (Canada). Child self-reports lifestyle habits at age 13 that were linearly regressed on parent-reported televiewing at age 2 while adjusting for potential confounders.
Every 1 h 13 m increase in daily televiewing was prospectively associated with a 8.2% increased risk of unhealthy eating habits (unstandardized b = 0.05; 95% CI, 0.02 to 0.07), 10.1% decrease in eating breakfast on weekdays (unstandardized b = -0.06; 95% CI, -0.09 to -0.04), 13.3% increase in BMI (unstandardized b = 0.38; 95% CI, 0.26 to 0.50), 4.7% decrease in student engagement (unstandardized b = -0.07; 95% CI, -0.14 to -0.004), and 5.8% increase in concurrent screen time (unstandardized b = 0.06; 95% CI, 0.02 to 0.11). Post hoc simulations of noncompliance with AAP recommendations support their implementation.
Excessive toddlerhood televiewing was prospectively associated with less optimal health and self-invested behavioral dispositions. Lifestyle habits not only affect metabolic risk but may also influence personal success outcomes. These independent relationships, observed more than a decade later, suggest a need for better parental awareness of the way children invest their limited waking hours could affect their long-term life course trajectories.
对于非常年幼的孩子来说，看电视是一种常见的消遣方式。高暴露可能会对身心健康产生负面影响。对于早期接触与青少年生活方式选择的关系，我们知之甚少。
估计幼儿期的电视观看与青少年时期的生活方式指标之间的后续关联。
参与者是来自加拿大魁北克儿童发展纵向研究出生队列的 986 名女孩和 999 名男孩。儿童在 13 岁时自我报告生活方式习惯，这些习惯与父母报告的 2 岁时的电视观看情况一起进行线性回归，同时调整了潜在的混杂因素。
每天看电视时间增加 1 小时 13 分钟，与不良饮食习惯的风险增加 8.2%相关（未标准化 b=0.05；95%CI，0.02 至 0.07），工作日不吃早餐的比例降低 10.1%（未标准化 b=-0.06；95%CI，-0.09 至 -0.04），BMI 增加 13.3%（未标准化 b=0.38；95%CI，0.26 至 0.50），学生参与度降低 4.7%（未标准化 b=-0.07；95%CI，-0.14 至 -0.004），同时屏幕时间增加 5.8%（未标准化 b=0.06；95%CI，0.02 至 0.11）。对不符合 AAP 建议的非依从性的事后模拟支持其实施。
幼儿期过度看电视与不太理想的健康和自我投入的行为倾向相关。生活方式习惯不仅会影响代谢风险，还可能影响个人成功的结果。这些在十多年后观察到的独立关系表明，需要更好地让父母意识到孩子如何利用他们有限的清醒时间，这可能会影响他们的长期生活轨迹。
