The patient’s belief and knowledge about his or her
illness is the most important factor of disease control;
the aim of present study is to perform a systematic
review-based meta-analysis of health belief and its
dimension’s mean score in diabetic patients.
The present systematic review and meta-analysis was
conducted in 2020. Data were gathered by searching
the Google Scholar, Scopus, PubMed, Web of Science,
and Science Direct databases from 2010 to 2020. Key
words were “health belief”, “HBM”, “diabetic patients”,
“diabetes mellitus”. To estimate the pooled
score of health belief and its dimensions, the randomeffects
meta-analysis was performed using STATA 15.
The presence of heterogeneity across the studies was
assessed with the I2 statistic. A forest plot was used
to report the results.
The mean health belief obtained from the two methods,
fixed (3.422, 95% CI: 3.128–3.716) and random
(3.422, 95% CI: 3.128–3.716) what are the same, is the
same. The strongest dimension is “perceived benefits”
with an mean (3.8) and the weakest dimension is “perceived
sensitivity” with an mean (3.0).
Conclusions. Policymakers and decision makers in the
field of hygiene and controlling non-communicable
diseases should focus on the role of patients’ awareness
of their disease and try to improve it. In the meantime,
the dimension of “perceived sensitivity” needs more attention.
Strategies such as holding training classes and
using technological infrastructure to promote this concept
should be used.
