The present study investigated blood pressure levels as well as the prevalence of hypertension among adult Parengi Porja tribals of village Munchingput Mandalam, Visakhapatnam district, Andhra Pradesh, India. A cross-sectional study was used to collect data on systolic blood pressure (SBP), diastolic blood pressure (DBP), and pulse rate. A total of 137 adults (100 males and 37 females) were measured and classified into three age groups, that is, Gr-I: 23 to 32 years, Gr-II: 33 to 42 years, and Gr-III: ≥ 43 years. Negative significant sex difference in SBP among age group I (; ) was observed. Positive significant sex difference in DBP among age group I (; ) was also observed. Significant age group difference was noticed for SBP (; ) among males. Based on SBP, the prevalence of prehypertension and stage I hypertension in males was 25.0% and 5.0%, respectively. Similarly, in females the prevalence of prehypertension and stage I hypertension based on SBP was 32.4% and 5.4%, respectively. On the basis of DBP, the prevalence of stage I hypertension in males was 5.0%. Similarly, in females, the prevalence of stage I hypertension based on DBP was 5.4%. Our results suggest that females of this ethnic group were more prone to have prehypertension and stage I hypertension than males.
