비타민D 결핍
비타민D 결핍
And your children’s health in the news tonight.
What kids aren’t getting enough of and the risk that schools are already preparing for.
Nightly News begins now.
We hear a ton about the dangers of getting too much sun in this country.
Tonight, though, there is a stern warning about how our kids aren’t getting enough.
The proof is what researchers are calling shockingly low levels of vitamin-D, the one we get from sunshine.
Our report tonight from NBC News chief medical editor Dr. Nancy Snyderman.
In a study out today in the Journal Pediatrics <단수취급> 소아과<학>,
researchers report 7 out of 10 American children have very low levels of vitamin-D.
Levels too low, putting them at potential risk for heart disease, weak bones, even rickets.
“We were rather shocked when we saw the numbers.”
Roughly 대략 9 percent of those ages 1 to 21, about 7.6 million children, adolescents, and young adults
have vitamin-D levels that could be deficient 부족한, 결핍되어 있는.
Another 50.8 million have higher levels of vitamin-D
but still low enough to be considered insufficient 부족한.
And one group at particular risk: African-American girls.
Their dark skin filters the sun automatically, lowering vitamin-D levels.
In the 1930s, vitamin-D was added to milk
and pediatricians 소아과 의사 believed weak bones and rickets <단수취급> 구루병, 골연화증 would become problems of the past.
But children substituting 대용하다 sport drinks for milk and spending hours in front of one screen or another is taking a toll.
“4-hours a day of using computers or watching TV or playing video games,
they were 60 percent higher risk of having vitamin-D deficiency.”
Getting enough vitamin-D is free.
It means getting out in the sunshine about 10 to 15 minutes a day without screen.
That amount of time won’t hurt you and it could ward off 피하다 serious illness.
Illnesses like osteoporosis 골다공증, high blood pressure, heart disease, and diabetes 당뇨병.
Diseases pediatricians are seeing early
and that can follow people well into adulthood.
