VIT1PHYS indicates whether sample adults had used a first vitamin supplement to improve physical performance. Only sample adults who had taken one or more vitamin supplements during the past 30 days (VITMOSUPNO) were asked their reasons for using vitamin supplements.
Other reasons for using a first vitamin supplement that were recorded by the survey, and the associated IPUMS NHIS variables, are:
- VIT1DRUGCOST (Prescription or non-prescription drugs too expensive)
- VIT1HCREC (Health care provider recommended)
- VIT1IMMUN (Improved immune function)
- VIT1MEDCOST (Medical treatment too expensive)
- VIT1MEDFAIL (Medical treatment did not help)
- VIT1MENT (Improved mental ability or memory)
- VIT1RELREC (Family or friends recommended)
- VIT1SEX (Improved sexual performance)
- VIT1WELL (General wellness)
- VIT1SPORT (Improved sports performance)
- VIT1TREAT (Treat a disease or health problem)
