Objetivo. Analizar las desigualdades en comportamientos de riesgo en adolescentes de 10 a 19 años en México y documentar los cambios en las brechas y la magnitud de la desigualdad. Material y métodos. Análisis de las encuestas nacionales de salud de 2000 y 2012 estimando para ambas la brecha absoluta y relativa en indicadores de comportamiento de riesgo, así como el índice de desigualdad de la pendiente. Resultados. Para comportamientos sexuales, el uso de métodos anticonceptivos muestra un índice de desigualdad elevado e incrementado entre 2000 y 2012 tanto para hombres como para mujeres; esto es, menor probabilidad de uso para menor nivel socioeconómico. Para el consumo de tabaco y alcohol, la probabilidad es mayor entre quienes cuentan con mayores recursos. Conclusiones. El análisis presentado señala retos importantes en términos de la atención de comportamientos que comprometen la salud de los adolescentes mexicanos y su bienestar futuro. Comprender mejor los elementos asociados a las desigualdades identificadas es necesario para el desarrollo de acciones preventivas eficaces.

“…The age of sexual activity has declined in Latin America and the Caribbean, depending on gender and socioeconomic level [16], even though births from adolescent mothers in Mexico remain high [17]. It has become harder for adolescent mothers to successfully handle daily situations linked to academic and work-related development [18], a situation that exacerbates gender inequality by creating uncertainty for young women, especially low-income adolescent woman [16,19,20].…”

Adolescent pregnancy rates are high worldwide. However, insufficient information exists regarding the frequency of birth control methods used before the first pregnancy and postpartum. In the current study, we analyzed the association of sociodemographic factors with the knowledge of birth control methods and their use before and after pregnancy in a sample of adolescents in Mexico City. A cohort study was conducted on 600 pregnant adolescents in Mexico City, from 2013 to 2017, at a health care institution providing prenatal care. Participants were assessed during the second trimester and four months postpartum. The questionnaire explored the knowledge of birth control methods, their use, and other associated factors. Two logistic regression models were implemented to identify potential variables associated with the lack of birth control method use before and after pregnancy. The mean age of participants was 15.4 + 1 years, of which, 48% and 65.2% used a birth control method before pregnancy and postpartum, respectively. We found that the main factors associated with increased risk of not using any birth control method before pregnancy included being under the age of 15 years, school dropout, having an educational lag, initiation of sexual life before the age of 15, and having a mother who did not inform their child about contraceptives. By contrast, variables associated with a higher risk of not using any contraceptive methods after pregnancy included educational lag, lower level of education, and the fact that the adolescent had not used any birth control prior to the pregnancy.

“…15,16 One of the main limitations of the study is the lack of randomization, which might result in differential exposure to HPV. However, in Mexico, a small percent (<20%) of women are sexually active before age 16,17 and when both groups were compared month at 7, there was non-inferiority in HPV16; thus, we can infer that both groups are homogeneous in month 7. Besides, the prevalence of the two types of HPV in the vaccine in women younger than 34 years is less than 2.2%, 18 hus the results are unlikely to be a consequence of the response to exposure, through sexual intercourse; even if differential, the prevalence is low and would have a very small effect in GMT´s.…”

The effect of a booster dose of HPV tetravalent vaccine after 51 months: implications for extended vaccination schedules Salud Publica Mex. 2018;60:666-673. AbstractObjective. To asses the non-inferiority between two different vaccination schedules one month after the administration of the third dose. Materials and methods. We evaluated the anti-HPV 16/18 antibody titers induced by quadrivalent HPV vaccine administered using two different schedules in girls 9 to 10-year-old girls: a traditional (0-2-6) and an alternative (0-6-50). Blood samples were collected at month 7, 21 and 51. Results. The antibody geometric mean titer ratios one month after the application of the third dose -month 51 for the alternative and month 7 for the traditional-were 1.55 for HPV16 (95%CI, 1.15-2.08) and 1.53 for HPV18 (95%CI, 1.12-2.09). The seropositive rate was above 99% in both groups. Conclusions. The application of an alternative 3-dose schedule in 9 to 10-year-old girls induces a non-inferior immune response compared to the standard one month after the last dose. Further research is needed to understand the minimal number of doses and their timing to provide the best coverage for HPV infection.
