Folic acid tied to better grades in Swedish teens

Our Review Summary

This is a story about a recent study published in the journal Pediatrics which found an association between folic acid levels and school grades in a cohort of Swedish teens.  This story did a reasonable job of describing this cohort study.  It explained that the small study may not be meaningful in the US where many common foods are fortified with folic acid – making it unlikely that there are children with low or marginal intakes of this B vitamin.


Why This Matters

Understanding how to interpret study results and knowing the appropriate questions to ask in order to understand how those results might be applicable is a valuable skill.  Helping people think about studies of nutrition in context and whether they might apply to other populations is important. This story demonstrated those skills.


Does the story adequately discuss the costs of the intervention?

Not Applicable

Not applicable.  Costs weren’t mentioned, but we didn’t think that was a necessity in this case.

Does the story adequately quantify the benefits of the treatment/test/product/procedure?


The story provided the data on the summation of grades showing the difference in folic acid levels in the children in the highest and lowest groups.  While it is nice to have absolute grade difference provided, it would have been useful to indicate whether these differences were statistically significant or whether the differences in folic acid intake were clinically significant.

Does the story adequately explain/quantify the harms of the intervention?

Not Applicable

Not applicable.  Harms not mentioned. The story could have mentioned the potential for excessive folic acid intake to interfere with vitamin B12 uptake which, though unlikely in a teen population, could mask symptoms of B12 deficiency. But we’ll give it the benefit of the doubt on this.

Does the story seem to grasp the quality of the evidence?


The story mentioned the fact that the study was small and that the population differed in an important way from teens in the US who consume food that is supplemented with folic acid.  It also pointed out that the study was not a randomized controlled trial so there may have been other differences between the groups of teens found to have high and low amounts of folic acid.

Does the story commit disease-mongering?


The story did not engage in overt disease mongering.

Does the story use independent sources and identify conflicts of interest?


The story included quotes from independent sources who helped provide context and perspective on the study and its results.

Does the story compare the new approach with existing alternatives?


The story mentioned that the food supply in the US was folic acid fortified.

Does the story establish the availability of the treatment/test/product/procedure?


The story stated that folic acid is one of the ‘B’ vitamins and that at least in the US, is found in fortified foods.

The story could have also mentioned that folic acid is a common ingredient in multivitamin formulations.

Does the story establish the true novelty of the approach?


The story provided good background on folic acid intake.

Does the story appear to rely solely or largely on a news release?


This story did not appear to rely solely on a news release.
