> I do wonder what would cause other wise healthy adults to have higher disease rates than other countries. Possibly a measurement difference. More frequent testing leads to both earlier detection and thus higher reported occurrence. Another factor might be that it gives more false positives and thus higher stress levels and from that, higher incidence of various disorders. But also, the article doesn’t exactly say “other wise healthy adults“, it says “Americans with healthy behaviors, for example, those who are not obese or do not smoke”. Those people might have a disease from bad habits they had earlier in live. They also may not have truly bad habits, but yet lead a more sedentary live than similar groups in other countries, etc.
