- W2904520307 abstract "Several studies have shown a relationship between indoor particulate matter and cardiovascular diseases in adults though this relationship is yet to be clarified in children and adolescents. This study purposed to investigate the relationship between indoor air particulate matter and blood pressure in 10-14 year old rural and urban children in Eastern Cape, South Africa. A cross sectional study of 10-14 year old children was carried out in selected rural and urban schools of the Eastern Cape. Anthropometry was performed and blood pressure measured. Indoor air particle counts were determine. Blood pressure parameters and body mass index (BMI) were converted to percentiles for height, sex and age. Prevalence of overweight/obesity were 10.9%/14.0% and hypertension/prehypertension were 12%/20%. Hypertension/prehypertension were more prevalent in rural compared to urban adolescents. All blood parameters were higher in rural adolescents and higher in rural girls compared to boys. In hypertensive/prehypertensive adolescents, systolic blood pressure (SBP) showed a strong correlation with BMI, waist, hip and mid upper arm circumferences (0.50, 0.51, 0.52, 0.53, 0.49; p<0.05 respectively) though SBP was only modestly associated with these variable in normotensive adolescents. Indoor particle counts were higher in rural schools. Blood pressure did not correlate with indoor air particulate matter though there was a weak correlation between PM2.5, 5, 10 and heart rate in rural adolescents. Indoor air particle failed to show any relationship with blood pressure parameters in urban adolescents. Rural adolescents had higher blood pressure and heart rates. Indoor particulate matter may be associated with blood raised pressure via sympathetic activation as suggested by higher heart rates." @default.
