Background Hypertension is strongly associated with adverse cardiovascular outcomes and was the leading modifiable associated factor for global disease burden in 2010. Analysis of modifiable associated factors will be important to those concerned with mitigating the adverse effects of hypertension. We studied factors associated with hypertension in adults aged 25–64 years of age in Cambodia in order to help develop strategies for planned new initiatives for prevention and control of hypertension.

Methods Using data from a nationwide survey in Cambodia assessing the prevalence of associated factors for non-communicable disease in 2010 (WHO STEPs survey), 5017 participants between the ages of 25 and 64 years were included in a secondary analysis of the prevalence and predictors of hypertension.

Results The prevalence of prehypertension in this sample was approximately double that of overall hypertension (27.9% vs 15.3%). Male sex, increasing age and known cardiovascular associated factors, including higher Body Mass Index (BMI), dyslipidaemia, impaired fasting glycaemia, and abdominal obesity were all associated with an increased prevalence of hypertension. In multivariate models, increasing age was the strongest associated factor for hypertension (OR 8.79, 95% CI (5.43 to 14.2)), whereas, higher BMI was the primary associated factor associated with prehypertension (OR 3.27, 95% CI 2.21 to 4.82).

Conclusions Modifiable cardiovascular-associated factors are strongly correlated with prehypertension and hypertension in Cambodia, and may be a focus of public health and primary care strategies to mitigate subsequent ischaemic heart disease and stroke. A national strategy aimed at increased screening and adherence to medical therapy is a necessary first step to reduce burden of disease and related morbidities.
