The data of age, sex, ABO blood type and pathological status of patients of different diseases i.e. hypertension and migraine (252 hypertension patients i.e. 165 males and 87 females, and 263 migraine patients i.e. 99 males and 164 females) were collected from various zonal hospitals at Kangra, Dharamshala, Palampur and Dr. R.P. Medical College, Tanda, Kangra, H.P (India) and from the individuals by scheduling, interviewing and questionnaire methods. The control sample was taken from the blood bank donors. The distribution pattern of ABO blood groups was B (35.269%) � O (26.409%) � A (24.121%) � AB (14.201%). The phenotypic distribution in blood groups A, B, AB and O was found to be 0.2412, 0.3527, 0.2641 and 0.1420, respectively.The incidence of hypertension was found to be highest in blood group O (43.25%) followed by group A (27.78%), group B (22.62%), group AB (6.35%). The frequency of migraine was highest in blood group O (30.03%) followed by group A(29.28%), then group B (28.52%) and group AB (12.17%). The relative risk for hypertension and migraine was found to be highest in group O and lowest in group AB. From the present study it was concluded that blood group B is the most prevalent in district Kangra of Himachal Pradesh and least prevalent is AB.
