Fertility and fertility-related behavior among Mexican-American and non-Hispanic white female adolescents.

Ethnic differences in fertility-related behavior are examined in a community-based probability sample of 706 Mexican-American and 317 non-Hispanic white females aged 13 through 19 years. Mexican-Americans are more likely than whites to have had a live birth, but are no more likely to have been pregnant and are less likely to have had sexual intercourse. Sexually experienced Mexican-Americans, however, are twice as likely as whites to have been pregnant. Among those ever pregnant, Mexican-Americans are more likely to have had a live birth, while whites are more likely to have had an abortion. Ethnic differences remain strong when socioeconomic status and indicators of social instability are controlled statistically, lending more support to the "minority status" hypothesis than to the "characteristics" hypothesis concerning the fertility-related behavior of minority group members.
