Trends in prevalence and magnitude of vitamin and mineral supplement usage and correlation with health status.
The 1980 Food and Drug Administration Vitamin and Mineral Supplement Use Survey and the 1986 National Health Interview Survey used similar questions and procedures to estimate and identify trends in the prevalence and magnitude of supplement usage in the United States. A comparison of the two surveys reveals that prevalence of supplement use among adults decreased slightly, from 42% in 1980 to 38% in 1986. The magnitude of supplement use has also decreased; users reported taking a mean of 2.15 supplements in 1980 compared with a mean of 1.77 in 1986. The prevalence of supplement users identified as light users increased from 42% in 1980 to 57% in 1986. Supplement usage was more likely and more intense among individuals who had one or more health problems and among individuals who perceived their health as very good or excellent. The findings indicate that supplement usage remains a widespread behavior linked to popular conceptions of good health and well-being but one that is susceptible to change.
