Although family health history (FHH) information has tremendous potential in the prevention of common complex diseases such as heart disease and cancer, lack of knowledge about one's own FHH among the public hinders its utility. Older individuals often desire to contribute to the well-being of younger generations and also play critical roles in disseminating this information. This study evaluated psychosocial factors associated with the extent of FHH communication within families. Older adults (N = 110) were interviewed at three senior centers in an urban community. Multivariate Poisson regression analysis showed that respondents who received FHH from a parent reported 41 % more family members with whom they shared FHH (b = 0.34, p < 0.001) controlling for the family network size. Furthermore, one unit increase in the number of family members with whom respondents exchange reciprocal emotional support (b = 0.04, p < 0.01), perceived familiarity with own FHH (b = 0.14, p = 0.01), and self-efficacy to share FHH (b = 0.18, p = 0.02) were associated with 4, 15, and 20 % increases in the number of family members with whom respondents shared FHH, respectively. Future efforts may inform older adults about their important role in modeling FHH communication behavior to encourage information sharing in future generations while providing information about how to collect and disseminate FHH to increase their familiarity and ability to share FHH within the family.
