Diastolic Blood Pressure Response During Non-isometric Exercise and Its Relationship with Family History of Hypertension

The purpose of this study was to find an association (if any) between isolated diastolic blood pressure response to non - isometric exercise and family history of hypertension. Diastolic blood pressure response (DBPR) of 32 apparently healthy young adults (aged 18 - 30 years) were noted during 10 minutes of cycling on a bicycle ergometer and during their recovery after exercise and their family history of hypertension were recorded by a separate observer.4 sets of data were rejected due to faulty technique and rest 28 sets of data were checked for association by a 2 by 2 contingency table and by performing Chi - Square test.17 subjects showed normal DBPR, 11 of them did not have any family history of hypertension, which should be a normal occurrence. And out of 11 subjects with abnormal/exaggerated DBPR, 6 had positive family history of hypertension, which was inconclusive. The test result gave us a more than 25% chance of randomness of association between abnormal/exaggerated DBPR and family history of hypertension, which refuted the association, meaning abnormal/exaggerated DBPR to non - isometric exercise and family history of hypertension can both be predictors of future hypertension but there is no association between them.
