Notes

• All datasets span multiple survey cycles (1999-2023)
• Each includes year and seqn columns for merging
• Data types are harmonized across cycles
• Variable names match CDC documentation

For detailed variable information, use term_search() or visit the CDC NHANES website.

Warning: CDC may change data periodically. The data was aggregated as best as possible to reconcile variable types that changed across cycles. ALWAYS reference the CDC documentation with nhanesdata::get_url(dataset)!

See get_url() documentation.
