Cardiovascular risk factors in the Bedouin population: management and compliance.
BACKGROUND
Until three decades ago coronary heart disease and stroke were considered rare in the Israeli Bedouin population. Today, this population shows increasing high prevalence compared to the Jewish population.


OBJECTIVE
To evaluate the prevalence of diagnosed cardiovascular risk factors among Bedouins (hypertension, diabetes mellitus, dyslipidemia), and to assess compliance with follow-up tests and drug treatment.


METHODS
The study included all listed patients aged 20 years and older in eight clinics in major Bedouin towns, and in two large teaching clinics in Beer Sheva (Jewish population). Risk factor data were extracted from the clinics' computerized databases. For those diagnosed with hypertension, diabetes or dyslipidemia, drug purchasing data were collected from the pharmacy database to determine compliance with treatment, and from the central laboratory mainframe (HbAlc and low density lipoprotein-cholesterol) to evaluate follow-up and control.


RESULTS
A significantly higher prevalence of diabetes in all age groups was found in the Bedouin population compared to the Jewish population; age-adjusted results show a prevalence of 12% vs. 8% respectively (P < 0.001). The prevalence of dyslipidemia and age-adjusted hypertension was lower among Bedouins (5.8% vs. 18.2%, P < 0.01 and 17% vs. 21%, P < 0.001 respectively). Two-thirds of hypertensive Bedouin patients and 72.9% of diabetic Bedouin patients were not compliant with treatment. For dyslipidemia only 10.4% of the Bedouins were compliant compared with 28.2% in the Jewish population (P < 0.001).


CONCLUSIONS
Compliance with drug therapy and follow-up tests was found to be a major problem in the Bedouin population.
