The objective of this research was to investigate associations among self-reported health status, chronic conditions, and use of dietary supplements containing botanicals and describe reasons for use among U.S. adult supplement users. This was a cross-sectional analysis using data from the 2009-2014 National Health and Nutrition Examination Survey (NHANES). Supplement information was collected with a 30-day recall interview. Self-reported general health status and doctor-informed diagnoses of chronic conditions were assessed using a health status questionnaire. We used weighted multivariate logistic regressions to assess associations between supplement use and perceived health and number of chronic conditions. Participants were 16,958 non-institutionalized U.S. adults aged 20 years and older. Adults with excellent or very good self-perceived health were more likely to use botanical supplements than adults with good perceived health (adjusted odds ratio [aOR], 1.48; 95% confidence interval [CI], 1.28-1.74). Adults with three or more chronic conditions were more likely to report using botanical supplements than adults with no chronic conditions (aOR, 1.49; 95% CI, 1.13-1.69). The most frequently reported reasons for both non-botanical and botanical supplements use were "personal choice or influenced by advertisements or word of mouth," "improve health," and "specific health conditions" (93.3%, 84.2%, and 64.7%, respectively). While perceptions of health are more positive among adults using botanical supplements, chronic conditions and reasons for botanical supplements use related to personal choice, improving health, or addressing specific conditions were more likely. Differentiating botanical supplements from other complementary and integrative therapies may be useful for facilitating a deeper understanding of the reasons.
