Four groups of 10th-grade students were selected from the upper tails of four distributions based on a stratified random sample of the nation's high schools (N = 95,650): Two groups consisted of mathematically gifted subjects (boys n = 497, girls n = 508); the remaining two groups comprised environmentally privileged students (boys n = 647, girls n = 485). The former represented approximately the top 1% on a standard measure of quantitative ability, whereas the latter represented approximately the upper 1% of a conventional SES index. These four gifted/privileged groups were then compared to one another, by gender, and to their gender equivalent normative cohorts on 43 indices of medical and physical well-being. Although higher levels of physical health are found in both gifted and privileged groups (relative to the norm), medical and physical well-being appears to be more highly associated with mathematical giftedness than extreme levels of socioeconomic privilege. To the extent that these findings may be linked to the construct general intelligence, they confirm and extend the view that the nomothetic span (network of correlates) of general intelligence permeates a variety of important and valued nonintellectual domains (cf. Brand, 1987).
