Maybe lack of vitamin D as kids are spending more time inside and also using sunscreen when they are outside.
Could very well be.
Vitamin D is also known as the "sunshine vitamin" and who's been preaching for decades that the sun was BAD for us?
Yeah, the gubmint.

I’m careful about too much sun. My brother died of skin cancer when he was 48. However, with being careful of too much sun, you also have to worry about getting enough vitamin D.
