Objective:

to identify the presence of students’ sexual uncertainty attending a senior high school in southeastern Mexico.

Material and Methods:

a descriptive and cross-sectional study whose target population consisted of 190 adolescents aged 15 to 18 years, attending a senior high school in Ciudad del Carmen, Campeche. We applied a sociodemographic data with questions about sexual risk behavior and whether they have received information about sexuality, sexually transmitted infections, the Human Immunodeficiency Virus and the Acquired Immunodeficiency Syndrome. The Sexual Uncertainty Scale was applied.

Results:

most of the students have received information about sexuality; just over half of the students have information about sexually transmitted infections, the Human Immunodeficiency Virus and the Acquired Immunodeficiency Syndrome. In prevention of risk behavior, about 4% of the students have taken the rapid test for detection of human immunodeficiency virus. Regarding the sexual activity, 31.1% responded that they have had sexual intercourse. The result of the difference of the overage in sexual uncertainty was higher in men (X ̅= 17.72, SD = 6.03). In relation to risky sexual behavior, men showed a significant difference compared to women with an average of (X ̅ = 19,25, SD = 21,94).

Conclusions:

it is determined that sexual uncertainty is a factor that influences a person's behavior and determines whether to take health protective measures, such as avoiding risky sexual behavior. Adolescents, whose sexual uncertainty is less, are less likely to engage in this type of behavior.
