Area of Science:

  • Nutritional Science
  • Public Health
  • Sociology of Health

Background:

  • Growing consumer interest in supplements necessitates understanding usage drivers.
  • Previous research often overlooks distinctions between specific vitamin and herbal supplement use.
  • This study differentiates between various supplements and introduces a frequency measure for vitamin use.

Purpose of the Study:

  • To investigate the demographic and behavioral determinants of vitamin and herbal supplement consumption.
  • To analyze whether factors influencing supplement use vary across different types of supplements.
  • To assess the impact of a vitamin use frequency measure on understanding usage patterns.

Main Methods:

  • Utilized logistic and ordinal logistic regression analyses.
  • Employed a large-scale dataset from the National Health Interview Survey (NHIS) 2000, comprising 24,834 participants.
  • Examined supplement usage by breaking down broad categories into specific vitamins and herbs.

Main Results:

  • Women and Non-Latino Whites demonstrated higher overall supplement usage compared to men, non-Latino Blacks, and Mexicans.
  • Analysis indicated that determinants of use can differ based on the specific vitamin or herbal supplement.
  • Incorporating a measure of frequency for vitamin use did not significantly alter the observed patterns.

Conclusions:

  • Demographic trends in supplement use exist but are insufficient for a complete understanding.
  • Further research is required to explore the specific reasons behind the use of particular supplements.
  • Investigating the sources of information individuals rely on for supplement choices is crucial for public health initiatives.
