Abstract
Background: Globally, dietary and herbal supplements (DHS) are used frequently
by adults and especially the elderly to control and prevent chronic disease. However,
little is known about DHS use in sub-Saharan Africa. We estimated the prevalence and
frequency of DHS use among elderly residents of the Keta Municipality in Ghana.
Methods: A descriptive cross-sectional survey was administered to 580 male
and female elderly (65+ years) residents in the Keta municipal area in the Volta
region. Respondents were selected using a multi-stage sampling approach involving
a random selection of sub-municipalities, communities, and individuals at each level.
The survey tool developed for the study collected recall data on socio-demographic
characteristics; DHS use behavior, health history, and reasons for using DHS. Logistic
regression analysis was used to identify independent determinants of DSH use.
Results: About 42% of respondents reported the use of a DHS in the last month.
Almost 90% of users reported the use of multivitamins or mineral supplements. More than
90% reported taking their supplement daily and more than 65% of users
took supplements at least twice daily. Elderly who have completed secondary school
or a higher level of education were significantly more likely to use any DHS (OR=4.9;
95% CI: 2.08, 4.93). Those who were regularly taking medicines for any diagnosed
disease were more likely to also take supplements (OR=17.9; 95% CI: 10.0, 32.0).
The main reason for using DHS was to improve health (90.5%). About half of DHS
users identified health workers as their prescribing source (59.5%). However, 30% of
all users indicated self-prescription for DHS.
Conclusion: Multivitamin supplements and to a lesser extent, herbal supplements are
used regularly by almost half of elderly Ghanaians residing in the Keta Municipality.
The public health system needs to recognize this frequent use of DHS and to assure
safety in its use among this critical age group.
