title: Family history of hypertension and rates of sodium transport: absence of an association in population-based studies.
abstract: In a series of population-based studies, the relationship between a family history of hypertension and sodium transport was examined. In the total sample of 417 individuals, and in each sex-race-specific sub-sample, no significant differences were noted in red cell sodium-lithium countertransport, sodium concentration, or passive leak. A higher proportion of hypertensives was not found in the group with a positive family history, and blood pressures were only slightly higher in those--compared to those without--a positive family history. If family history of hypertension is associated with levels of countertransport, it would appear that the relationship is weak in the general population.
