背景：电视和睡眠不足与不良的心理和身体健康有关。本研究评估协会的电视观看和卧室电视与睡眠时间从婴儿期到midchildhood.METHOD：我们研究了1864名儿童在项目Viva。父母报告了孩子平均每天看电视和睡眠（6个月和1-7岁每年）以及卧室电视的存在（4-7岁每年）。我们使用混合效应模型来评估电视暴露与同期睡眠的关联，调整儿童年龄，性别，种族/民族，母亲的教育，和income.RESULTS：六百四十三名儿童（35%）是种族/民族少数民族; 37%的家庭收入为70000美元。从6个月到7岁，平均（SD）睡眠时间从每天12.2（2.0）小时减少到9.8（0.9）小时;看电视从每天0.9（1.2）小时增加到1.6（1.0）小时。4年时，17%的人有卧室电视，7年时上升到23%。一生中每天看电视时间每增加1小时，睡眠时间就会缩短7分钟（95%置信区间[CI]：4 - 10）。卧室电视的相关性因种族/民族而异;卧室电视与种族/民族少数儿童每天睡眠时间缩短31分钟相关（95% CI：16至45），但在白色、非西班牙裔儿童中不相关（每天睡眠时间减少8分钟[95% CI：-19至2]）。结论：更多的电视观看，以及种族/民族少数儿童卧室电视的存在，与婴儿期至儿童中期的睡眠时间缩短相关。
BACKGROUND:Television and insufficient sleep are associated with poor mental and physical health. This study assessed associations of TV viewing and bedroom TV with sleep duration from infancy to midchildhood.METHOD:We studied 1864 children in Project Viva. Parents reported children's average daily TV viewing and sleep (at 6 months and annually from 1-7 years) and the presence of a bedroom TV (annually 4-7 years). We used mixed effects models to assess associations of TV exposures with contemporaneous sleep, adjusting for child age, gender, race/ethnicity, maternal education, and income.RESULTS:Six hundred forty-three children (35%) were racial/ethnic minorities; 37% of households had incomes $70000. From 6 months to 7 years, mean (SD) sleep duration decreased from 12.2 (2.0) hours to 9.8 (0.9) hours per day; TV viewing increased from 0.9 (1.2) hours to 1.6 (1.0) hours per day. At 4 years, 17% had a bedroom TV, rising to 23% at 7 years. Each 1 hour per day increase in lifetime TV viewing was associated with 7 minutes per day (95% confidence interval [CI]: 4 to 10) shorter sleep. The association of bedroom TV varied by race/ethnicity; bedroom TV was associated with 31 minutes per day shorter sleep (95% CI: 16 to 45) among racial/ethnic minority children, but not among white, non-Hispanic children (8 fewer minutes per day [95% CI: -19 to 2]).CONCLUSIONS:More TV viewing, and, among racial/ethnic minority children, the presence of a bedroom TV, were associated with shorter sleep from infancy to midchildhood.
