An analysis of federal data released today showed 9% of children ages 1 through 21 are deficient in vitamin D while another 61% have higher levels that still are considered insufficient. Lower levels were more common among girls, adolescents and people with darker skin, the study in Pediatrics found. The researchers said unhealthy lifestyles that include too much time indoors watching TV or playing video games likely contribute to the low vitamin D levels.
