The analysis sample consisted of 23,006 men and 17,368 women who provided responses regarding parental history of alcoholism. Chi-square analyses indicated differences with respect to paternal alcoholism and gender, education, employment and household of origin composition with male gender, a college degree, not working, and having grown up with both biological parents were associated with a lower frequency of paternal alcoholism in this sample. A similar pattern was observed with respect to maternal alcoholism, and additionally, race/ethnicity was implicated with maternal alcoholism less frequently acknowledged among Hispanic respondents (Table 1). Of these factors, several appeared particularly robust: having grown up with both biological parents (over 50% reduction); having a college degree (~30% reduction); and, in the case of maternal alcoholism, Hispanic ethnicity (43% reduction).
