Dear Editor,
I read with interest the article on the Use of Complementary and
Alternative Medicine among Persons with Diabetes Mellitus published by Yeh
et al. The study is based on a nationally representative telephone survey
of English speaking respondents who are 18 years or older. The study
concluded that the prevalence of CAM therapy use among persons with
diabetes is comparable to that among the general population; however the
use of CAM therapies
specifically to treat diabetes is much less common than in other chronic
disorders.
The study is based on a small sample that may be technically
representative of the general population of the US, but the demographics
show that it fails to
capture people with juvenile diabetes, ethnic minorities, non-English
speakers, or those without phones. These lacks may significantly bias the
estimates of CAM use. The discussion section of the article quotes studies
of
Fairfield et al, Wolsko et al. and Kessler et al. regarding the condition
specific use of CAM, present study however does not state whether the
respondents who reported use of CAM to treat diabetes were given a clear
definition of “condition specific” use during the data collection. For
reader’s ease some basic information should have been included in the
article such as a brief description of the telephonic questionnaire; time
of the day the calls were made, if they were made for a specific area code
and how long the average interviews were.
The study found that there is a modest use of commercial diet programs for
weight loss or gain, but the article does not discuss obesity and other
common
related factors for diabetes, see Table 1 Demographic and Clinical
Characteristics of Respondents. The
authors also do not clarify why they chose certain things as CAM and left
out others.
This letter is to suggest some changes for the improvement of future
studies.
