Key result
Urban populations in Western Samoa had higher mean blood pressures and approximately double the prevalence of hypertension compared to rural counterparts, partly due to differences in adiposity.
Why the study?
Are there differences in mean blood pressures or the prevalence of hypertension between rural and urban Polynesian populations of Western Samoa?
Cross-Sectional
Are there differences in mean blood pressures or the prevalence of hypertension between rural and urban Polynesian populations of Western Samoa?
Urban living in Western Samoa is associated with higher blood pressure and a doubled prevalence of hypertension compared to rural living, partly driven by differences in adiposity.
Warrants location-specific hypertension screening in Western Samoa; hypothesis-generating for adiposity-targeted prevention in transitioning populations.
Blood pressure was measured in the rural and urban male and female Polynesian populations of Western Samoa to determine if differences existed in mean blood pressures or in the prevalence of hypertension between these groups. It was found that, in the urban population, both males and females had higher mean blood pressures and approximately double the prevalence of hypertension found in their rural counterparts. There was an age-related rise in mean blood pressure and in the prevalence of hypertension in all groups. Approximately half of the difference in mean blood pressure and hypertension prevalence between rural and urban groups appeared to be due to difference in adiposity. Age and body mass index were significantly and independently correlated with systolic and diastolic blood pressure in each group. The prevalence of hypertension was greater in obese subjects.

Zimmet et al. (1980) conducted a cross-sectional in Hypertension. Urban environment vs. Rural environment was evaluated on Mean blood pressure and prevalence of hypertension. Urban populations in Western Samoa had higher mean blood pressures and approximately double the prevalence of hypertension compared to rural counterparts, partly due to differences in adiposity.
