Environmental risk factors in relation to hypertension and stroke are noise, overcrowding and violence that can influence the prevalence of morbidity and mortality in humans. This study aimed at determining the influence of environmental factors on the occurrence of hypertension and stroke in Ohafia, Abia State Nigeria.

A total of 587 participants were involved in this study that comprise of males 219(37.3%) and females 368(62.7%). The data were analyzed using Statistical Package for Social Sciences (SPSS) version 20.0. The results were presented in frequency tables and charts. The chi-square tool was used to determine the statistical influence of the variables. Results obtained from data collected showed that 161 (27.43%) of the participants had hypertension while 426 (72.57%) were normotensive. Also 3(0.51%) cases of stroke were observed while 584 (99.41%) were non-stroke cases. Again, 76(12.95%) and 2(0.34%) of the participants agreed that they had hypertension and stroke respectively due to environmental violence and overcrowding. On the same note, 47(8.01%) and 2(0.34%) of the participants agreed that they had hypertension and stroke respectively due to environmental noise. The findings of the study showed a statistically significant with noise, overcrowding and violence in the occurrence of hypertension at P<0.05 and not statistically with stroke at P>0.05.
