You've probably heard that increased TV watching, high-calorie snacking, and decreased physical activity are linked to skyrocketing rates of child obesity. But recent research points to a new culprit: lack of sleep.
"Children who don't sleep enough are at much greater risk for obesity than children who do sleep enough," says Frederick J. Zimmerman, PhD, chair and professor in the Department of Health Services at UCLA School of Public Health, and one of the lead researchers in a recent study.
Although it isn't normal to have lead in your body, a small amount is present in most people. Environmental laws have reduced lead exposure in the United States, but it is still a health risk, especially for young children.
What causes lead poisoning?
Lead poisoning is usually caused by months or years of exposure to small amounts of lead at home, work, or day care. It can also happen very quickly with exposure to a large amount of lead. Many things can contain or be contaminated with lead: paint, air, water, soil, food, and manufactured goods.
The most common source of lead exposure for children is lead-based paint and the dust and soil that are contaminated by it. This can be a problem in older homes and buildings.
Adults are most often exposed to lead at work or while doing hobbies that involve lead.
Who is at highest risk of lead poisoning?
Lead poisoning can occur at any age, but children are most likely to be affected by high lead levels. Children at highest risk include those who:
Live in or regularly visit homes or buildings built before 1978. These buildings may have lead-based paint. The risk is even higher in buildings built before 1950, when lead-based paint was more commonly used.
Are immigrants, refugees, or adoptees from other countries.1 They may have been exposed to higher lead levels in these countries.
Are 6 years old or younger. Young children are at higher risk because:
They often put their hands and objects in their mouths.
They sometimes swallow nonfood items.
Their bodies absorb lead at a higher rate.
Their brains are developing quickly.
Others at risk for lead poisoning include people who:
Drink water that flows through pipes that were soldered with lead.
Work with lead either in their job or as a hobby (for example, metal smelters, pottery makers, and stained glass artists).
Eat food from cans made with lead solder. These types of cans aren't made in the United States.
Cook or store food in ceramic containers. Some ceramic glaze contains lead that may not have been properly fired or cured.
Eat or breathe traditional or folk remedies that contain lead, such as some herbs and vitamins from other countries.
Live in communities with a lot of industrial pollution.
