JAMA Pediatrics Patient Page Offers Parents Advice on Vitamin D

By Carolyn Crist

(Reuters Health) - Parents and caregivers should be aware of the three ways children can get the vitamin D they need, says the author of a JAMA Pediatrics Patient Page.

Although many people know calcium and vitamin D are vital for building healthy bones, not everyone knows calcium can only be absorbed when vitamin D is present, Dr. Megan Moreno of the University of Wisconsin School of Medicine and Public Health in Madison notes in her one-page primer intended for parents and caregivers.

"Vitamin D is sometimes misunderstood and underappreciated, especially when it works as a silent partner with calcium," said Moreno.

The patient page is based on recommendations given by the American Academy of Pediatrics. It emphasizes the best ways for children to obtain vitamin D through sunlight exposure, diet and supplements.

Current guidelines recommend that infants under 12 months get 400 international units of vitamin D daily from all sources and that children and adolescents get 600 IU daily. For infants who are fully or partially breastfed, daily vitamin D supplementation is recommended until the child is weaned and drinking fortified milk.

"Summer is coming up, and there will be many opportunities for kids to be out in the sun, eat more meals at home and be around their parents more," Moreno said in a telephone interview. "This is an opportune time for parents to reflect on the ways to get vitamin D."

Foods rich in vitamin D, such as salmon or tuna, could be cooked on the grill alongside summer vegetables, she said. Other fatty fish, fortified milk and yogurt, fortified cereals and eggs also have good amounts of vitamin D.

"Multivitamins may not be necessary if children eat a varied diet," Moreno said. "Sun is also an important way to get vitamin D, though sun protection is also important."

Sun protection is essential to protect a child's skin from sunburn and skin cancer risk, though sunscreen can decrease vitamin D creation. Most children receive enough sun exposure in their day-to-day lives, even with sun protection, to be sufficient, Moreno writes.

A third option for getting vitamin D is taking a supplement. Although daily multivitamins aren't recommended as necessary for children, Moreno writes, supplementing with vitamin D could help those who don't get it through food or sun exposure. These supplements are often available as liquids, chewables or pills, and some have both calcium and vitamin D.

"Balancing health recommendations can be really tricky for families," she said. "We create these pages so parents can receive the best information possible to make these choices."

Recent studies of vitamin D have shown its life-long health benefits, especially for the immune system. Researchers are now studying the role vitamin D may play in autoimmune diseases, including type 1 diabetes in children and adolescents.

Lower levels of vitamin D in kids could be a factor in diabetes, for instance, said Dr. Majid Aminzadeh of Ahvaz Jundishapur University of Medical Sciences in Iran.

"Besides its role in calcium homeostasis, vitamin D has an important immune-modulation effect," said Aminzadeh, a pediatric endocrinologist who recently published a study of vitamin D status in diabetic children. "However, its role in autoimmune diseases such as type 1 diabetes is under discussion."

Moreno advises parents who aren't sure whether their children receive enough vitamin D to talk to their pediatrician.

"Vitamin D has become a more common, big picture topic that we discuss in clinical situations," she said. "Advice can get murky, so it's important for everyone to know the recommendations."
