Journal of the National Medical Association
Date of Publication
This study was designed to investigate the prevalence of hypertension in Jamaica. Jamaica has an area of 4,411 square miles and is divided into 14 parishes. The visited districts were randomly selected. The sample population was selected based upon a two-stage stratified random sampling design. Each dwelling in the 'Sampling Universe' had an equal probability of being selected. The survey team spent a week in the districts in each parish selected. Employing the Statistical Institute of Jamaica's (STATIN) two-stage stratified random sampling design, preselected house-holds were visited. Non-response was documented and considered in the final analysis. Only individuals 15 years and older were allowed to participate in the study. The 2,064 subjects who participated were the basis for estimates of hypertension. Following logistic regression analysis, the main risk factors for hypertension are being female, advancing age, obesity, having diabetes and having a family history of hypertension. Jamaica has a point prevalence of hypertension of 30.8% in the 15-and-over age group. These findings would greatly assist in formulating policies to deal with this scourge of society.....
