Study shows teens at risk of hypertension due to lack of sleep
NEW YORK A new study shows that teenagers who don’t get enough sleep face the risk of elevated blood pressure.
The study examined 238 boys and girls aged 13 to 16 and found that 11 percent of them slept less than 6.5 hours a night, while 26 percent of them woke up frequently, a phenomenon called low sleep efficiency. One out of every seven of the teenagers had high blood pressure, while those with low sleep efficiency increased their risk of high blood pressure threefold.
The study appears in the Aug. 19 issue of the journal Circulation.
Low vitamin D levels increase likelihood of hip breakage in elderly women
NEW YORK Researchers at the University of Pittsburgh have found that low vitamin D levels increase the risk of hip fractures in elderly women by 70 percent.
According to HealthDay News, 50 percent of old people who have hip fractures end up in nursing homes, while 20 percent die within the first year due to related complications.
The researchers found that for every 25-nanomole reduction in vitamin D per liter of blood, hip-fracture risk increased by 33 percent. The risk was 71 percent for women with the lowest vitamin D levels.
The report, published in the Aug. 19 issue of the Annals of Internal Medicine, was based on data collected from 800 women aged 50 to 79.
