Both systolic and diastolic blood pressures are generally believed to vary in relation to various factors like sex, age, body build, altitude, socio-economic condition, chronic diseases, etc. but the evidences are not always unequivocal. This paper aims to study the effect of intergenerational change, age, sex, and body mass index on blood pressures and to see the effects of migration on blood pressures among the two generations of the Tibetan immigrants in Northern India. Findings from research on 1st and 2nd generation adult Tibetans indicate that there are no significant differences in blood pressures between two generations in both the sexes which may have contributed to their food habits.
