"Passive TV viewing related to children's sleeping difficulties
A recent Finnish randomized population-based study shows that TV-viewing, and particularly exposure to adult-targeted programs, such as current affairs programs, TV series and police series and movies, markedly increases the risk of sleeping difficulties in 5-6 year old children. Also passive exposure to TV increases sleeping difficulties.
Questionnaires concerning TV viewing, sleep disturbances, and psychiatric symptoms were administered to 321 parents of children aged 5-6 years, representing the typical urban population in three university cities in Finland.
The results of the study have been published recently in the Journal of Sleep Research.
Main results:
1. All the families that participated in the study had at least one TV set. In 21% of families, there was a TV set in the children's room. On average, the TV was switched on for 4,2 h a day. Children actively watched TV for a mean of 1,4 h a day and were passively exposed to TV 1,4 h a day.
2. Both active TV viewing and passive TV exposure were related to shorter sleep duration and sleeping difficulties, especially sleep-wake transition disorders and overall sleep disturbances.
3. There was also a clear association between the contents of actively viewed TV programs and the sleep problem scores. Watching adult targeted programs, such as current affairs programs, police series, movies, series, was related to an increased frequency of various sleeping difficulties.
4. Watching TV alone was related to sleep onset problems.
5. Watching TV at bedtime was also associated with various sleeping problems, especially sleep-wake transition disorders and daytime somnolence.
6. Particularly high passive exposure to TV (>2,1 h/day) and viewing adult-targeted TV programs were strongly related to sleep disturbances. The association remained highly significant when socio-economic status, family income, family conflicts, the father's work schedule, and the child's psychiatric symptoms were controlled for statistically. The adjusted odds ratios were 2.91 (95% CI 1.03-8.17) and 3.01 (95% CI 1.13-8.05), respectively. There was also an almost significant interaction between passive TV exposure and active viewing of adult programs (AOR 10.14, 95% CI 0.81-127.04, p=0.07). By contrast, active TV viewing time and the viewing of children's programs were not correlated with sleep problems.
Most of the previous research has concentrated on active TV viewing while passive TV exposure has only rarely been considered. Passive TV exposure can be particularly harmful to young children because it increases the risk of children coming into contact with programs intended for adults.
Quality sleep is essential for children's wellbeing and health. Therefore reducing the quantity of passive TV exposure and limiting children's opportunities to watch adult-targeted programs might help to reduce children's sleeping problems and increase average sleep duration, which could further lead to beneficial changes in children's daytime behavior. Parents should be advised to control the quantity of TV viewing, to monitor the program content viewed, and to limit children's exposure to passive TV. Watching TV at bedtime should be discouraged."

I have mentioned before that watching television may be linked to a decline in childrens abilities. The mechanism of this could well be sleep deprivation as sleep is important for memory consolidation and other brain processes. There is also the link between sleep and obesity - if children sleep less they are more likely to get obese. It could well be that the increase in obesity in recent years is due in part to the widespread lack of sleep in children.

I agree that TV viewing can affect children's sleeping habits but there are other causes of it as well that may not be as obvious. It could be stress, maybe from school or at home, and they are trying to cope with it by spending more time watching TV than lying in bed thinking of all that's causing them the anxiety.
Everybody have their own version of sleeping problems, even kids. Here's a site that talks about sleeping problems and ways on how to deal with it.
