Impact of first sexual intercourse on the sexual and reproductive life of young people in a capital city of the Brazilian Northeast

The univariate and bivariate analysis were performed by descriptive statistics and Pearson's Correlation Coefficient Test or T-test, respectively. Tukey's post hoc test was used as post hoc test and significant variables on the bivariate analysis (p < 0.05) were also included in the multifactor analysis of variance model. Schooling (p < 0,001) and menarche's age (p < 0,001) influenced the age of first sexual intercourse and this, in turn, showed significant negative correlation (p < 0.01) with the number of partners and pregnancies of young women.

Thus, the earlier the young women start sexual activity, the higher the number of pregnancies and sexual partners until the moment of their reproductive life. Thus, early first sexual intercourse had a negative repercussion on these variables.
