Cures Everything?

History of vitamin D recommendations for children

Historically: 400 IU/day (tsp of cod liver oil) in “high risk” children.

1997 (IOM) and 2003 (AAP): 200 IU/day to prevent rickets (by 2 months of age, AAP) for all infants and children.

2008 AAP: 400 IU/day for all children beginning soon after birth

Strong pressure to revise government guidelines led to new IOM panel being formed in 2008.

2011: IOM new guidelines of 400-600 IU/day.

Globally, recommendations vary from none (India and others) with no milk fortification to 800 IU/day (Canadian Pediatric Society for infants in far north of Canada in Winter).

The language of dietary guidelines: Dietary Reference Intakes

Dietary Reference Intake (DRI): Daily nutrient recommendations based on age and gender; set at levels to decrease the risk of chronic disease

EAR - Estimated Average Requirement

RDA - Recommended Dietary Allowance

AI - Adequate Intake

UL - Tolerable Upper Intake Level

What are the DRIs?

Estimated Average Requirement (EAR)

Value to meet the needs of 50% of individuals.

Recommended Dietary Allowance (RDA)

Recommended daily levels of nutrients to meet the needs of almost all (97-98%) healthy individuals in a specific age and gender group.

Adequate Intake (AI)

Single value when not enough data or for use to reflect intake of breast-fed babies.

Tolerable Upper Intake Level (UL)

Maximum long-term intake that most likely won’t pose risks for health problems for almost all healthy people in that age and gender group. NOT a target intake. Derived based on pharmacological toxicity principles (No Adverse Effect Level, etc).

Dietary Reference Intake

The Estimated Average Requirement (EAR) is the intake at which the risk of inadequacy is 0.5 (50%) to an individual.

The Recommended Dietary Allowance (RDA) is the intake at which the risk of inadequacy is very small—only 0.02 to 0.03 (2% to 3%).

The Adequate Intake (AI) does not bear a consistent relationship to the EAR or the RDA because it is set without being able to estimate the average requirement. It is assumed that the AI is at or above the RDA if one could be calculated.

At intakes between the RDA and the Tolerable Upper Intake Level (UL), the risks of inadequacy and of excess are both close to 0. At intakes above the UL, the risk of adverse effects may increase.

Dietary Reference Intake

Effect of multiple days of observation on the apparent distribution of nutrient intake.

The mean is the same for both, but the percentage of individuals with intakes less than the Estimated Average Requirement (EAR) is overestimated by the 1-day observations. Adapted from NRC (1986); originally from Hegsted (1972).

Improper Use of the DRIs

Mean nutrient intake of group is often compared to the RDA

Mean intakes ≥ RDA are assumed adequate Mean intakes < RDA are assumed deficient HOWEVER, this is not correct

Why improper?

If mean intakes ≥ RDA are assumed adequate, there may still be a large proportion of the group with inadequate intakes

If mean intakes < RDA are assumed deficient, there may still be individuals who have nutrient requirements below the RDA and therefore cannot be assumed to be deficient if intake is < RDA.

THEREFORE,

Use EAR if you are looking at groups

Use RDA if you are looking at an individual

Vitamin D: infants

2008 AAP and Pediatric Endocrine Society and 2011 IOM recommend 400 IU/day consistent with nearly 100 years of evidence of its effectiveness in preventing rickets.

Fundamental wording distinction:

AAP “all infants soon after birth” and for formula fed infants who do not consume 1 L of formula

IOM DRI reflects average intake over first year of life

AI used by IOM due to lack of data on outcomes at different 25-OHD levels in infants and historical evidence that 400 IU is effective.

Vitamin D infants: formula-fed

Infant Formula Act: 40 to 100 IU/100 kcal (27 to 67 IU/100 mL). Every formula bottle must be in that range at usual dilutions.

Usual US formulas have 60 IU/100 kcal (40 IU/100 mL), but due to overages, average content is about 75 IU/100 kcal (50 IU/100 mL).

First two months of life infants may typically receive 600-800 mL/day (240-320 IU/day) by label claim or 300-400 IU/day by average analysis of actual content.

Some suggest that all formula-fed infants get a vitamin D supplement until at 1 liter. Some babies never reach 1 L of formula intake nor is that a necessary goal.

How much vitamin D is needed?

Siafarikis et al, Arch Dis Child 2010 (online)

Breast-fed infants in Germany, no seasonal

variation in results. 250 IU daily is plenty.

But endpoint was 25-OHD level of uncertain

interpretation.

So, should we supplement formula-fed babies?

Supplementing formula-fed babies (several million babies/yr at $50-100/baby) would be costly with no evidence of benefit.

About 300 IU/day in first weeks is close enough to save a few hundred million dollars.

Supplements not really needed for formula fed babies.

Vitamin D: Breastfed babies

Give 400 IU/day as a single dropper. Do not use high concentration drops (AAP and FDA 2010).

Can give from first week of life as D alone, multivitamins (tri or poly), or as multivitamins and iron (use for < 2500 g or < 37 weeks gestation at birth).

Change to multivitamins with Fe at 4 months (AAP 2010).

Give to partially breast-fed until fully weaned.

Why is vitamin D not given to BF infants?

Pediatricians:

In the South we have sun!!

Cut-off for winter sun is south of Atlanta – some

controversy about this.

Old ideas of vitamin D sufficiency die hard.

Families:

No clinical problem apparent to families.

Concern about spitting, dislike of vitamins. It’s a hassle.

Cost: not available on public assistance. One 50 mL

bottle is about $8 or about 18 cents/day.

Mixed messages from advocacy groups and

pediatricians.

What should a child’s vitamin D level be?

Serum 25-OHD concentrations: IOM 2011

“Committee concluded that serum 25OHD levels of 16 ng/ml (40

nmol/liter) cover the requirements of approximately half the

population, and levels of 20 ng/ml (50 nmol/liter) cover the

requirements of at least 97.5% of the population.”

“Serum concentrations of 25OHD above 30 ng/ml (75 nmol/liter)

are not consistently associated with increased benefit, and risks

have been identified for some outcomes at 25OHD levels above 50

ng/ml (125 nmol/liter).”

“The Committee finds that the prevalence of vitamin D inadequacy

in the North American population has been overestimated by some

groups due to the use of inappropriate cut-points for these

categories that greatly exceed the levels identified in this report.”

Measuring 25-OHD levels

Routine 25-OHD measurement not addressed by IOM, no evidence of value in healthy children.

Serum 25-OHD monitoring in preterm infants?

“Close monitoring of vitamin D status through each change in parenteral and enteral feedings must occur to assure adequate vitamin D status of these [preterm] infants” (Taylor et al., NeoReviews 2009).

“Routine measurement of serum 25-OHD levels in premature infants is not supported by currently available clinical research. No studies have related serum 25-OHD level in these infants to specific clinical outcomes.” (IOM 2011)

Risk/benefit and cost considerations on both an individual basis and public health basis should be considered in evaluating need for 25-OHD levels in any group.

Vitamin D supplementation and bone density in healthy children

Cochrane review (Winzenberg et al, Nov. 2010): No overall benefit. Very small effect in those with 25-OHD < 14 ng/mL.

Authors conclusions “These results do not support vitamin D supplementation to improve bone density in healthy children with normal vitamin D levels, but suggest that supplementation of deficient children may be clinically useful.

Note that deficient is defined by review < 14 ng/mL and that RDA of 600 IU/day will bring > 97.5% of the population of children to a level above 20 ng/mL.

How much calcium and vitamin D are children in the United States

consuming now?

DRI values for 1-18 years of age

RDA of 600 IU/day likely meets needs of most teens.

In adolescents, may have some greater risk with 600 IU/day RDA of not reaching 25-OHD of 20 ng/mL in more than 2.5% of population.

Clinical concerns of this are unclear.

Intake of 800 IU/day provides some margin, especially for dark-skinned population and those with no sun exposure.

DRI values did not address obese children specifically, nor did they address children with chronic illnesses.

No evidence that 25-OHD levels 40-80 ng/mL are dangerous in children, but limited data.

Don’t focus too much on one nutrient

How to get to 600 IU/day?

Diet: 1 L milk has 400 IU. Few kids drink that.

Fortified foods extremely variable. Yogurts, juices range from 0-200 IU/serving.

Cereals and other foods vary. Daily Value (DV) is 400 IU.

So “Good Source” is 40 IU and “Excellent Source” is 80 IU/serving.

Natural sources in fish are limited for most kids.

Be cautious of high dose supplements.

Other non-bone benefits? Lots of association studies, very few trials

Immune – Type 1 DM?

Despite claims, no real evidence, especially in US.

Data on asthma are conflicting and no controlled trials.

Autism/Other neurological outcomes?

No real data – available data are ambiguous at best.

Anti-infectious, esp. influenza?

Maybe – esp. TB. Influenza data is limited

Cancer?

No data in children.

Cardiovascular?

No data in children.

Prevention of prematurity?

One study, not yet published. Need large trials

Significant effect overall for Influenza A, not B or overall influenza. Wide Confidence intervals.

Subgroup analysis confusing and inconsistent

Substantial dropouts probably invalidate study

No vitamin D levels!!

Preliminary evidence, needs confirmation, large trials, varying doses with monitoring of levels

A couple of other issues

Obese children have lower serum 25-OHD. Unclear if this is a true deficiency and what is cause and effect.

Evidence that vitamin D OR calcium are major factors in weight regulation is questionable.

Vitamin D2 is probably comparable to D3 at moderate daily doses. May be less so at high intermittent doses.

Controversy about both safety and efficacy of intermittent high dose vitamin D – e.g. 200,000 units every 6 month. Not really recommended any more in children. May have very high acute levels and may not be as effective as daily or weekly dosing.

Conclusions

Controlled trials to identify vitamin D needs of children are

limited at best. Most of literature is “association” studies with

strong publication and other biases.

Research needs include short and long-term outcomes of

various intakes/25-OHD levels.

There are no compelling data establishing any single

“insufficient” 25-OHD level in children. 25-OHD > 20 ng/mL

consistent with available data.

“The plural of anecdote is not data.”

Conclusions

Breast-fed babies need their vitamin D drops.

Healthy kids need to get reasonable amounts of calcium and vitamin D. Dairy or other fortified foods are best sources, but may need small supplements such as are found in MVIs for children.

Beware of high dose supplements.

Do not buy into idea that chronic illnesses in children are vitamin D-related or treatable until reliable evidence says they are.

Can always try higher doses on an individual child, generally staying to UL values.

No role currently identified for routine monitoring of 25-OHD in healthy children.
