Among adolescents, gonorrhea levels are particularly high, and incidence among blacks and Hispanics is higher still. In both women and men, these strains may cause anal, head, and neck cancer. Males generally have less frequent contact with physicians for reproductive health care. Teens are particularly at risk for STIs because their feelings of invincibility make them prone to engage in unprotected sex. Methods Incidence data for the past decade on three common bacterial STDs—syphilis, gonorrhea and chlamydia—were obtained for as many as 16 developed countries from official statistics, published national sources or scientific articles, and unpublished government data.
The seriousness of the problem is approached through discussion of the prevalence and health impact, the determinants behavioral, social, biological, institutionalcontrol strategies, and educational strategies.
Adolescents and sexually transmitted diseases.
Special difficulties affecting chlamydia reporting arise from "silent" cases—i. A central goal of this cross-national comparison is to assess the incidence of syphilis, gonorrhea and chlamydia among young people in developed countries. However, data were available only from an experimental, nonrepresentative sentinel system of STD clinics, and were in aggregated form, were only for the period and had no age detail. Avoid sexual activity while under treatment for an STD. West Germany, the Netherlands and Switzerland, where reporting quality is medium or low, also had low rates, but their actual rates would be somewhat higher after allowing for underreporting. Overall, syphilis, gonorrhea and chlamydia disproportionately affect adolescents and young adults.
