title: Do variations in blood pressures of South Asian, African and Chinese descent children reflect those of the adult populations in the UK? A review of cross-sectional data.
abstract: The objective of this study was to assess whether variations in BP in children of UK ethnic minority populations correspond to those seen in adults. A systematic literature review was carried out using MEDLINE 1966-2003 and EMBASE 1980-2003, supplemented by correspondence with expert informants, and citations from references. Five studies were identified. There were important differences between studies in terms of age and sex of samples, definition of ethnic minority children and methods of evaluating BP. Three studies of children of African descent reported lower mean SBP in boys from African descent compared to white boys, the differences being significant only in one study. In African descent girls, the mean SBP was significantly lower in one study, while DBP was significantly higher in one study. Four studies included children of South Asian origin. The Health Survey for England '99 reported on South Asian groups separately. Pakistani boys had a significantly higher age- and height-standardised mean SBP than the general population. The mean DBP was significantly higher in Indian and Pakistani boys than the general population. Pakistani and Bangladeshi girls had a significantly higher mean DBP than the general population. The other three studies, which combined South Asian subgroups found no significant differences in the mean BP between South Asians and white subjects. One study included children of Chinese descent and reported significantly higher mean DBP in Chinese boys and girls compared to the general population. Overall, BP across ethnic groups was similar. These similarities in BP patterns particularly in African, Bangladeshi and Pakistani descent children contrasts with those in the corresponding adult populations in the UK where BP is comparatively high in those of African descent and comparatively low in those of Bangladeshi and Pakistani descent.
