Background:The prevention of type 2 diabetes is a challenge for health institutions. Periodic blood glucose screening
in subjects at risk for developing diabetes may be necessary to implement preventive measures in patients prior to the
manifestation of the disease and to efficiently diagnose diabetes. Not only medical aspects, but also psychological and
social factors, such as the perception of risk (the individuals’ judgment of the likelihood of experiencing an adverse
event) influence healthy or preventive behaviors. It is still unknown if risk perception can have an effect on health
behaviors aimed at reducing the risk of diabetes (glucose screening). The objective of study was to identify factors that
influence glucose screening frequency.
Methods:Eight hundred randomized interviews, which were stratified by socioeconomic level, were performed in
Mexico City. We evaluated the perception of risk of developing diabetes, family history, health status and socioeconomic
variables and their association with glucose screening frequency.
Results:Of the study participants, 55.6% had not had their glucose levels measured in the last year, whereas 32.8% of
the subjects reported having monitored their glucose levels one to three times per year and 11.5% had their levels
monitoredfourormoretimesperyear.Riskperceptionwas significantly associated with the frequency of blood
glucose screening. Having a first-degree relative with diabetes, being older than 45 years and belonging to a
middle socioeconomic level increased the probability of subjects seeing a doctor for glucose screening.
Conclusions:Glucose screening is a complex behavior that involves the subjects’ perception of threat, defined as
feeling vulnerable to the development of diabetes, which is determined by the subject’s environment and his
previous experience with diabetes.
