USA Today (3/31, Marcus) reports, “About one third of Americans are not getting enough vitamin D,” according to a National Center for Health Statistics data brief released March 30 by the Centers for Disease Control and Prevention (CDC). The report “parallels what many other studies have suggested in recent years: that a large chunk of the population is at risk for low vitamin D levels.” Although approximately “two-thirds had sufficient levels…about a third were in ranges suggesting risk of either inadequate or deficient levels, says report author Anne Looker, a research scientist with the CDC.”
Meanwhile, the Los Angeles Times (3/30, Roan) “Booster Shots” blog reported that “1% had blood levels that were too high (greater than 125 nmol/L), putting them at risk of health problems.”
The Washington Post (3/30, Stein) “The Check Up” blog reported that recently, the Institute of Medicine “released new recommendations for how much vitamin D people should be getting on a regular basis.” In spite of “mounting pressure to urge many Americans to sharply boost their vitamin D levels, they did not advocate a huge increase.” In fact, “a 14-member expert committee concluded that most Americans and Canadians up to age 70 need no more than 600 international units of vitamin D per day.”
“The analysis showed that the risk for vitamin D deficiency differed by age, sex and race or ethnicity,” HealthDay (3/30, Preidt) reported.
WebMD (3/30, Mann) reported that people “who were at the lowest risk for vitamin D deficiency or inadequacy were children, males, non-Hispanic whites, and women who were pregnant or breastfeeding,” with the “risk of deficiency…lowest in children ages one to eight and increased with age until about age 30, the study showed.” WebMD also noted, “The analysis was based on data from the National Health and Nutrition Examination Surveys that includes about 5,000 Americans each year.”
