[Comprehensive sexual education in Mexico: an analysis of coverage, comprehensiveness and continuity of contents in Mexican public and private schools].

Objective:: To analyze coverage of comprehensive sex education (CSE) in high schools in Mexico and describe whether it is comprehensive, homogeneous and has continuity based on student reports of exposure to topics in three dimensions: reproductive and sexual health, self-efficacy and rights and relations.

Materials And Methods:: Within a probabilistic, cross-sectional survey with stratified, cluster sampling, a nationally representative sample of 3 824 adolescents attending 45 public and private high-schools in urban and rural areas completed questionnaires on CSE.

Results:: The proportion of adolescents reporting having received sex education from school personnel varies depending on topics and grade level.

Impact and economic evaluations of a combination prevention programme for men who have sex with men in Mexico.

Background: Despite the high-profile support for combination prevention programmes (CPPs) since 2008, there is little rigorous evidence on their impact and cost-effectiveness. In 2010, Mexico received funds from the Global Fund to implement a series of behavioural, biomedical, and structural interventions over 3 years targeted to men who have sex with men. The aims of the study were to estimate the impact of the programme across a range of outcomes and cost-effectiveness.

Self-collection of vaginal specimens for human papillomavirus testing in cervical cancer prevention (MARCH): a community-based randomised controlled trial.

Background: Vaginal self-sampling for human papillomavirus (HPV) DNA testing could increase rates of screening participation. In clinic-based settings, vaginal HPV testing is at least as sensitive as cytology for detecting cervical intraepithelial neoplasia (CIN) grade 2 or worse; however, effectiveness in home settings is unknown. We aimed to establish the relative sensitivity and positive predictive value for HPV screening of vaginal samples self-collected at home as compared with clinic-based cervical cytology.
