How Do Kids Spend Their Time?
Pre-school children spend about half their lives sleeping–averaging 86 hours a week. They spend 11 hours a week eating and put in a 30-hour “play” week–as they become acclimated to and learn to manipulate the world in which they live.

For adolescents the time spent sleeping drops rapidly each year–to less than 60 hours a week for some. Studies show that the time spent eating also declines during adolescence, although some parents of hungry teens might question this fact.

Caring Environment Promotes Sleep
Stress is a major reason for sleep disruption at any age, particularly during adolescence. A loving, caring environment promotes good sleep while fear of social rejection can keep us awake at night.

Many theorists see an evolutionary explanation. Unable to sleep safely in trees or on cliff edges, our ancient ancestors relied heavily on a close-knit social group for protection against predators during sleep. The human brain may continue to reflect those tendencies.

Sleep Loss Affects Kids’ Attention
When 11- and 12-year-old children were restricted to 6.5 hours of sleep per night for a week, they reacted with inattentiveness, irritability, noncompliance and sadness, according to a study conducted at Brown University.
The author called on health professionals to “be alert to...the potential impact that chronic periods of inadequate sleep can have on behavior and mood.

Under the Influence of Drowsiness
Drowsy drivers account for about 100,000 automobile accidents each year, according to the National Highway Traffic Safety Administration. These are typically single-vehicle crashes, occurring at night and usually as severe as those involving alcohol.
A Canadian study using a computer-based driving simulator determined that sleepiness resulted in significant impairment of driving ability, similar to that caused by alcohol.

U.S. Youth Most Likely To Use Drugs
European youth are more likely to smoke cigarettes and drink alcoholic beverages, but American adolescents have a much higher rate of illicit drug use, according to a 1999 survey of more than 100,000 10th grade students in the United States and 30 European countries.

Of 14,000 American youth surveyed, 41 percent said they had tried marijuana and 23 percent had used other illegal drugs. Among European students, marijuana use was 17 percent and other drug use only 6 percent. Even in the Netherlands, where many drugs are legal, only 28 percent of subjects had used marijuana.

About 37 percent of the European students had smoked a cigarette in the past 30 days (compared to 26 percent of Americans) and 61 percent had consumed alcohol (compared to 40 percent of Americans).

Does Your Baby Have Perfect Pitch?
Perfect pitch, which allows a person to identify a single musical note without comparing it to another, may be a trait possessed not just by the musically gifted but by all newborns. A study conducted at the Infant Learning Laboratory at the University of Wisconsin concluded that perfect pitch, but not relative pitch, appears to be a basic skill possessed by virtually all infants right after birth.

The author theorized that perfect pitch may be necessary to help a child “map” the world of sound but that this skill becomes less useful than relative pitch over time. Without relative pitch a person is unable to recognize the same song sung in a different key.

Skipping a Nap Can Be Dangerous
Letting a toddler skip a nap or stay up later can be dangerous, according to an Italian study of 292 patients treated at a children’s emergency center. Serious accidents most commonly occurred from 4 p.m. to midnight, and toddlers who had been awake all day were four times more likely to be injured as those who had napped. Overall, children who slept less than 10 hours a day had twice as many accidents as other children.

Kids Exposed to Violence at Risk
Children and adolescents exposed to violence–in the community, at home or even on television–generally have a high rate of depression and thoughts of suicide. As for community violence (the witnessing of drive-by shootings or other violence on the street), a recent study found that depression and thoughts of suicide seemed to be indirect rather than direct effects, varying with the degree to which the individual showed symptoms of post-traumatic stress disorder.

One survey indicated that 88 percent of inner city adolescents reported being exposed to some incident of street violence.

Does Depression Lead to Teen Smoking?
Adolescents diagnosed with depression are frequently cigarette smokers and some authorities have theorized that heavy cigarette use is a result of symptoms of depression. A recent controlled study, however, found no evidence that symptoms of depression brought about heavy smoking. Rather, “previous experimentation with smoking was the strongest predictor of becoming a heavy smoker.”

New Sleep Position Increase SIDS Risk
Before it was known that babies sleeping on their stomachs have an increased risk of sudden infant death syndrome (SIDS), numerous parents put their children to bed in that position. Grandparents resistant to change should realize, however, that babies used to sleeping on their backs are particularly vulnerable if placed on their stomachs even occasionally.

In one study, babies routinely placed on their stomachs were five times more likely to die of SIDS. For those used to sleeping on their backs, the risk of death when placed on their stomachs was 20 times higher compared to babies sleeping on their backs.

Sleep Position Means Fewer Deaths
When the American Academy of Pediatrics and other medical authorities around the world recommended that parents put their babies to sleep on their backs rather than their stomachs to prevent sudden infant death syndrome (SIDS), Japan’s Ministry of Health and Welfare delayed until studies could be conducted in that country.

As the death rate from SIDS fell around the world, the rate in Japan remained high. Six years later, based on Japanese studies showing that more babies die if they sleep on their stomachs, Japan accepted the new sleep recommendations.

Co-Sleeping Puts Babies at Risk
Many infants under the age of three months die each year when they share sleeping, often on a couch, with a parent and sometimes other children. Alcohol is often involved, and the adult may have rolled over on the baby, squashed it against the back of the couch or accidentally smothered it with bed clothes.

Do Implants Prevent Breast Feeding?
Women who have had breast implants or breast reduction surgery are often able to lactate and breast feed their babies, depending on the location of the surgical incision. The Food and Drug Administration has also ruled that silicone implants do not pose a danger for the baby.

An incision that goes around the entire circumference of the nipple may disrupt the milk ducts and the nerves to the nipple that are necessary for lactation.

Breast Feeding May Prevent Hypertension
Babies who are breast fed may have a lower risk of high blood pressure later in life, according to a study published in the British medical journal, Lancet [February 10, 2001]. A study of pre-term babies fed either formula or milk from a human donor showed that those drinking human milk had lower mean arterial blood pressure and lower diastolic blood pressure as teenagers.

The fat and sodium content of the milk was not found to be a factor.
