Purpose
We aimed to examine the prevalence of botanical dietary
supplement (BDS) use among Hispanics in the United
States (US) through a systematic review of the literature.
Methods
We performed a systematic review of BDS use among
adult Hispanics living in the US. Our strategy included
electronic database searches (CINAHL, EMBASE, Global
Health, CAB Abstracts, and Medline) with keywords: her-
bal, herb, medicinal plant, botanical and Hispanic or
Latino along with a manual search of retrieved references.
We included only studies with at least 1% Hispanics, pre-
valence estimates for Hispanics, and publication dates
1998-2011. We extracted information on study and sam-
ple characteristics, and rates of disclosures to clinicians.
Results
Of the 35 studies reporting prevalence of BDS use among
Hispanics, estimates ranged from 5% to 94% with a slightly
narrower range restricting to use over the past 12 months
(7-75%). Eighty-one percent (n=27) of studies included
non-Hispanics and 54% reported <500 subjects. Smaller
study size, regional location, convenience sampling, and
longer recall periods were associated with greater preva-
lence of BDS use among Hispanics (Chi square, Fisher’s
exact p<0.05). Studies with predominantly Hispanic sam-
ples also reported higher prevalence (p = 0.02). Of the pre-
dominantly Hispanic studies (n=11), 64% were conducted
in states bordering Mexico, all in both English and Span-
ish. Rates of use and disclosure to clinicians ranged from 7
to 65% and did not depend on the presence of underlying
health conditions. Health conditions included breast can-
cer, HIV, diabetes, heart disease, menopause, and
pregnancy.
Conclusion
Variability in reported prevalence of herb use among His-
panics depends, in part, on sample composition, possibly
related to the use of Hispanic-specific instruments. Disclo-
sure rates also varied widely, even in high risk illness.
Because of marked variability in estimates, more research
is needed to understand patterns of BDS use and disclo-
sure among Hispanic populations in the US.
