Conductas de riesgo asociadas con el inicio sexual temprano en adolescentes en México.

OBJETIVO: Analizar factores asociados con el inicio sexual temprano (IST) en mujeres y hombres de 15 a 19 años. Material y métodos. Utilizando información de adolescentes de la Encuesta Nacional de Salud y Nutrición 2022, se examina el IST (<15 años). Mediante un enfoque ecológico se ajustaron modelos probit multivariados por sexo para explorar factores sociodemográficos, psicosociales y de comportamiento sexual asociados con IST. RESULTADOS: Mujeres residentes en la región Pacífico-Centro y Pacífico-Sur, así como aquellas con pareja sexual de mayor edad por cinco años o más y hombres con estrato socioeconómico medio, tienen mayor probabilidad de IST que sus contrapartes de la región Pacífico-Norte, diferencia de edad con la pareja menor a cinco años y estrato bajo, respectivamente. Conclusión. Debido a que el IST en adolescentes está determinado por el contexto sociodemográfico y desigualdades de género, para una sexualidad saludable se requiere garantizar educación integral en sexualidad y servicios de salud de calidad.

Utilización de servicios preventivos de salud sexual y reproductiva antes y durante la pandemia de Covid-19 en México.

OBJETIVO: Analizar la utilización de servicios preventivos de salud sexual y reproductiva (SPSSR) en mujeres y hombres adultos antes y durante la pandemia Covid-19 y características sociodemográficas asociadas. Material y métodos. Usando la Encuesta Nacional de Salud y Nutrición 2018-19, 2021 y 2022 se analizó información sobre las pruebas realizadas de Papanicolaou y VPH, exploración clínica de mamas, mastografía, antígeno prostático y tacto rectal. Se construyeron modelos logísticos multivariados estratificados por sexo para explorar la asociación entre la utilización de los SPSSR y variables seleccionadas. RESULTADOS: Desde antes de la pandemia se observan bajas prevalencias en procedimientos diagnósticos, particularmente en hombres, que se agudizaron durante la emergencia sanitaria. La población con un perfil sociodemográfico más favorecido presenta mayor posibilidad de utilizar SPSSR; asimismo, se observan inequidades de género en algunas características. Conclusión. La experiencia de la pandemia puso de manifiesto la necesidad de mejorar y fortalecer los SPSSR para lograr una mayor eficiencia.

Salud sexual y reproductiva en población adolescente y adulta en México, 2022.

OBJETIVO: Caracterizar la situación de la salud sexual y reproductiva (SSR) en población adolescente (10-19) y adulta (20-49). Material y métodos. Utilizando la Encuesta Nacional de Salud y Nutrición 2022, se estimaron prevalencias e intervalos de confianza al 95% para indicadores de SSR. RESULTADOS: En adolescentes, 73.2% ha escuchado hablar de anticonceptivos, 88.1% saben que el condón se usa una sola vez y 60.4% que previene embarazos e infecciones de transmisión sexual; 22.8% ha iniciado vida sexual y 73.2% usaron condón en la primera relación sexual. En la población adulta, 42.7 y 38.0% no usaron protección en la primera y última relación sexual y 53.4 y 40.7% usaron condón en la primera y última relación sexual. Se encontraron diferencias en la atención de la salud materna entre adolescentes y adultas. Conclusión. Contar con información actualizada en SSR permite focalizar la atención en las necesidades de las personas.

Adolescent use of outpatient health services in Mexico: their health needs and associated factors.

OBJECTIVE: To estimate adolescent use of outpatient services, identifying their health needs and associated socioeconomic factors. MATERIALS AND METHODS: Using data from Ensanut 2018-2019, adolescents (ages 10-19) with health needs and those receiving care from health personnel (users) were identified. Needs were analyzed by sex and socioeconomic status (SES). Logistic models were used to assess the factors associated with the use of health care and choice of provider. RESULTS: 6% of adolescents reported health needs, of whom 64% used outpatient services. Respiratory and gastrointestinal infections were the principal health needs prompting use of services overall. However, by SES, motivations centered on pregnancy for the poor and accidental injuries for the wealthy. One in three adolescents with health needs, particularly the poorest, received no care. Living with a partner and having health insurance were the main predictors of use. Greater schooling among household heads and higher SES correlated with the use of private services. CONCLUSIONS: Despite being aware of their health needs, adolescents are the group that uses health services the least in Mexico. Promoting preventative and timely treatment for this population would encourage youths to seek care more often.

Severe Adverse Maternal and Neonatal Outcomes in Adolescent Mother-Newborn Dyads: A Multicentre Study in Latin America.

OBJECTIVES: To compare the risk of severe adverse maternal outcomes (SMO) and neonatal outcomes (SNO) and analyse their maternal correlates in adolescent mother-newborn and young mother-newborn dyads in secondary and tertiary care users in Latin America. METHODS: We performed a secondary analysis of the WHO Multicountry Survey on Maternal and Newborn Health database in 83 secondary and tertiary hospitals in seven countries in Latin America. We constructed a composite indicator of both SMO and SNO and estimated odds ratios (OR) comparing adolescent mothers (aged 12-19) with young mothers (aged 20-24). Our unit of analysis was the mother-newborn dyad. RESULTS: We found that the combination of SMO and SNO was three times more likely in adolescent mother as compared to young mother dyads (OR 3.56; 95% CI 1.67-7.59). SNO either alone or in combination with SMO were more likely in adolescents aged 12 to 16 than in young women (OR 1.27 and 4.87, respectively). CONCLUSIONS FOR PRACTICE: Adolescent mothers and their newborns are at an increased risk of severe adverse outcomes during child birth and in the first week postpartum compared to young mother dyads, especially young adolescents. Focusing on the dyad as a whole may facilitate a step towards integrated care which maximizes the health benefits of both mother and newborn. Continued efforts are needed to improve health care and prevention initiatives directed towards adolescent women and their newborns in Latin America.

"I Matter, I Learn, I Decide": An Impact Evaluation on Knowledge, Attitudes, and Rights to Prevent Adolescent Pregnancy.

Adolescent pregnancy is considered a priority public health issue because of its implications in the lives of young mothers, their children, and the well-being of the general population. In this paper, we describe an intervention targeting adolescents (aged 11-19 years old) in a rural context and estimate its impact on key outcomes relevant to early pregnancy prevention: knowledge and self-efficacy concerning sexual and reproductive health, knowledge of sexual and reproductive rights, and attitudes toward gender roles. Our study used a quasi-experimental design comprising 747 adolescents. Three difference-in-differences models (raw, adjusted, and by exposure level) with fixed effects estimated the changes in all outcome measures. Our results showed that the intervention community had a significant improvement in all outcomes, and this improvement was larger in those who received the highest-exposure level of intervention compared to a control community. Our study provides evidence that a community-based intervention, founded on comprehensive sexual education, is a promising approach to improve key outcomes related to early pregnancy in rural contexts. Further research should be undertaken to test how similar strategies focusing on multi-layer early pregnancy determinants work on other sub-groups of vulnerable adolescents, such as school dropouts or those living in disadvantaged circumstances.

[Changes in male condom use at first and last sexual intercourse in different birth cohorts]. / Cambios en el calendario de uso de condón masculino en la primera y última relación sexual en distintas cohortes de mujeres.

OBJECTIVE: Characterize the use of condoms in the first and last sexual intercourse in different birth cohorts, to observe possible differences among generations. MATERIALS AND METHODS: Using the National Survey of Boys, Girls and Women, 2015, representative at the national level, we adjust Poisson regression models to find associations between variables of interest and the use of condoms in first and last intercourse. RESULTS: Women from younger cohorts, with higher education and wealth are more likely to use a condom in their first and last sexual intercourse; speaking an indigenous language is associated with a lower likelihood of condom use at both events. Using condom in sexual debut increases the likelihood of using in last intercourse. CONCLUSIONS: There is a generational change in condom use at first and last sex among younger cohorts. The use of the condom in sexual debut favors its later use.

OBJETIVO: . Caracterizar el uso de condón en la primera y última relación sexual en diferentes cohortes para observar posibles diferencias entre grupos generacionales. MATERIAL Y MÉTODOS: .Mediante la Encuesta Nacional de Niños, Niñas y Mujeres 2015, representativa a nivel nacional, se ajustaron modelos de regresión Poisson para buscar asociación de variables de interés con el uso del condón en la primera y última relación sexual. RESULTADOS: Las cohortes más jóvenes, con mayor educación y riqueza tienen mayores posibilidades de usar condón en su primera y última relación sexual; hablar lengua indígena se asocia con menores posibilidades de uso en ambos eventos. El uso de condón en el debut sexual incrementa la posibilidad de uso en la última relación sexua. CONCLUSIONES: Existe un cambio generacional en el uso del condón en la primera y última relación sexual entre las más jóvenes. La utilización del condón en el debut sexual favorece su uso posterior.

[Provision of immediate postpartum contraceptivemethods in Mexico, 2018-19]. / Provisión de métodos anticonceptivos en el posparto inmediato en México, 2018-19.

OBJECTIVE: To identify sociodemographic and health services factors associated with receipt of immediate post-partum (IPP) contraception and the type of contraceptive method received. MATERIALS AND METHODS: We used the National Health and Nutrition Survey (Ensanut), 2018-19, which contains information on 4 548 women aged 12-49 years who gave birth. We described receipt of IPP contraception and method type and used multivariable logistic (n=4 544) and multinomial regression (n=2 903) to examine receipt of any modern method and type of method. RESULTS: 65% of women received IPP contraception. 56.8% of adolescents received long-acting reversible contraception (43.7% IUD & 13.1% implant). Being indigenous, having only one child, or receiving care in State Health Services/IMSS-Prospera or private sector facilities were associated with lower odds of receiving IPP contraception. CONCLUSIONS: We identify progress in the IPP contraception coverage among adoles-cents. Disparities persist in receipt of IPP contraception by type of health insurance.

OBJETIVO: Analizar la anticoncepción posparto (APP) y tipo de método anticonceptivo recibido según características sociodemográficas y de atención del parto de las mujeres. MATERIAL Y MÉTODOS: Se analizaron datos de la Encuesta Nacional de Salud y Nutrición (Ensanut) 2018-19 en4 548 mujeres de 12-49 años que tuvieron un parto. Se ajustaron modelos de regresión logística (n=4 544) y multinomial (n=2 903) con variables dependientes APP y tipo de anti-conceptivo recibido. RESULTADOS: Se encontró que 65% de las mujeres recibieron APP,y 56.8% de las adolescentes un método reversible de larga duración (43.7% DIU y 13.1% implantes). Ser indígena, tener un hijo, o recibir atención en los servicios estatales de salud/IMSS-Prospera o privadas, se asocia con menores posibilidades de APP. CONCLUSIONES: Se identificaron progresos en la cobertura de APP en las adolescentes. Persisten brechas de acuerdo con el asegura-miento en salud tanto en la recepción de APP como en el tipo de método recibido.

[Prevalence and associated factors of moderncontraceptive methods use among adolescents,2012 and 2018]. / Prevalencias y factores asociados con el uso de métodos anticonceptivos modernos en adolescentes, 2012 y 2018.

OBJECTIVE: To analyze the prevalence of modern contracep-tive methods (CM) use in adolescents aged 12 to 19 years in 2012 and 2018-19, and the factors associated with consistent use of modern CM. MATERIALS AND METHODS: Using the Health and Nutrition National Surveys 2012 and 2018-19 we calculated the outcome variables: long-acting reversible con-traceptives (LARC) use, dual protection and consistent use of CM. We estimated prevalence by sex and adjusted logistic models with consistent use (which is understood as CM use in the first and last sexual relationship) as a dependent variable. RESULTS: LARC use in last intercourse increased between surveys (4.1 to 6.3%). For women, being older, not having been pregnant, and school attendance increased the likelihood of consistent use. For men, school attendance increases the likelihood while cohabiting, early sexual initiation and having smoked more than 100 cigarettes reduces it. CONCLUSIONS: It is necessary to promote access and consistent use of MC, based on respect for sexual and reproductive rights.

OBJETIVO: Analizar la prevalencia de uso de métodos anticonceptivos (MAC) modernos en adolescentes de 12 a19 años en 2012 y 2018-19, y factores asociados con su uso consistente. MATERIAL Y MÉTODOS: A partir de las Encuestas Nacionales de Salud y Nutrición 2012 y 2018-19, se construyeron variables de interés: uso de anticonceptivos reversibles de acción prolongada (ARAP), protección dual y uso consistente de MAC. Se calcularon prevalencias y modelos logísticos para uso consistente de MAC. RESULTADOS: El uso de ARAP en la última relación se incrementó entre encuestas (4.1 a 6.3%). Tener mayor edad, no embarazo y asistencia escolar incrementaron la posibilidad de uso consistente en mujeres; en hombres, la asistencia escolar la incrementó, y vivir en unión, inicio temprano de vida sexual y consumir >100 cigarrillos la disminuyeron. CONCLUSIONES: Es necesario fomentar el acceso y uso de MAC de manera consistente, basado en el respeto a los derechos sexuales y reproductivos.

Intervention for the comprehension of menstrual cycle, body function and pregnancy in adolescents from rural context.

OBJECTIVE: To measure the impact of an intervention on adolescents' knowledge of the phase of the menstrual cycle with more likelihood of pregnancy and identify its associated factors. MATERIALS AND METHODS: A quasi-experimental study in two rural communities. Difference-in-differences analyses was performed. RESULTS: There was a 22.1% average reduction in wrong answers on the phase of the menstrual cycle with more likelihood of pregnancy in the intervention group versus the control group (p<0.001). We founded six factors associated with this knowledge: marry and have children, right to receive education and information on sexual and reproductive health; gender equity; use of the condom; condom self-efficacy; emergency and contraceptive pills. CONCLUSIONS: There is a prevailing need to improve -among sexuality topics- basic knowledge of reproductive biology, while at the same time insisting on the benefits of using birth control methods provided for practicing responsible sexuality.

OBJETIVO: Medir el efecto de una intervención en el conocimiento de los adolescentes sobre la fase del ciclo menstrual de mayor posibilidad de embarazo e identificar sus factores asociados. MATERIAL Y MÉTODOS: Estudio cuasiexperimental en comunidades rurales. Se realizó un análisis de diferencias en diferencias. RESULTADOS: Hubo una reducción promedio de 22.1% de respuestas incorrectas sobre la fase del ciclo menstrual de mayor posibilidad de embarazo en el grupo intervención vs. control (p<0.001). Se encontraron seis factores asociados con este conocimiento: casarse y tener hijos; derecho a recibir educación e información sobre salud sexual y reproductiva; equidad de género; uso correcto del condón; autoeficacia del uso del condón y pastillas anticonceptivas y de emergencia. CONCLUSIONES: Entre las diferentes temáticas de sexualidad, prevalece la necesidad de mejorar los conocimientos básicos sobre biología de la reproducción, insistiendo a la vez sobre los beneficios que conlleva el uso de métodos anticonceptivos para ejercer una sexualidad responsable.

[Adolescent motherhood in under 100 000 inhabitants communities in the first decades of the millennium]. / Maternidad en la adolescencia en localidades menores de 100 000 habitantes en las primeras décadas del milenio.

OBJECTIVE: To analyze the adolescent motherhood trend and associated factors in under-100 000-inhabitants communities. MATERIALS AND METHODS: Cross-sectional analysis of 16 686 women in under-100 000-inhabitants communities in Encuesta Nacional de Salud y Nutrición (Ensanut) 2006, 2012 and 100k 2018. We adjusted robust Poisson models with adolescent motherhood as dependent variable for women aged 12-19 and 20-24. RESULTS: Attending school and using modern contraceptives decrease adolescent motherhood prevalence in both age groups. Among adolescent girls, having a health financing scheme, and early sexual debut in the case of adults, is positively associated with adolescent motherhood. CONCLUSIONS: It is necessary to strengthen public policies seeking to modify structural factors that provide life choices, and to maintain and strengthen the actions and coverage proposed by Estrategia Nacional para la Prevención del Embarazo en Adolescentes (ENAPEA) targeting this population.

OBJETIVO: Analizar en localidades menores de 100 000 habitantes la tendencia de la maternidad en la adolescencia y factores relacionados. MATERIAL Y MÉTODOS: Análisis transversal de 16 686 mujeres en localidades menores de 100 000 habitantes a partir de la Encuesta Nacional de Salud y Nutrición (Ensanut) 2006, 2012 y 100k 2018. Se ajustaron modelos Poisson robustos con variable dependiente maternidad adolescente para mujeres de 12-19 y 20-24 años. RESULTADOS: Asistir a la escuela y usar anticonceptivos modernos disminuye la prevalencia de maternidad adolescente en ambos grupos de edad. Entre las adolescentes, contar con esquema de financiamiento en salud, y el inicio de vida sexual temprano para el caso de las adultas, se asocia positivamente con maternidad adolescente. CONCLUSIONES: Es necesario fortalecer las políticas públicas para modificar factores estructurales que proporcionen opciones de vida; es preciso mantener y fortalecer las acciones y cobertura propuestas por la Estrategia Nacional para la Prevención del Embarazo en Adolescentes (ENAPEA) focalizándolas en esta población.

[Maternal and child healthcare and adolescent maternity in under 100 000 inhabitants communities]. / Atención en salud materno-infantil y maternidad adolescente en localidades menores de 100 000 habitantes.

OBJECTIVE: To compare the coverage of continuous ma- ternal healthcare and early childhood care in women with and without adolescent motherhood (AM) who live in under-100 000-inhabitants communities. MATERIALS AND METHODS: Cross-sectional analysis of Ensanut 100k 2018 of 767 women aged 12 to 49 years living in under-100 000-in- habitants communities who had their last birth two years before the survey. RESULTS: Women with AM have lower continuous coverage of maternal care than those without AM (8.1 and 19.6%, respectively). Infant care coverage with adequate content was lower than 30%, and there were no differences between the groups. CONCLUSIONS: It is necessary to strengthen actions focused on this group of women in order to reduce the gaps in coverage and improve maternal and child health.

OBJETIVO: Comparar la cobertura de atención continua de salud materna y de atención en la primera infancia en mujeres con y sin maternidad en la adolescencia (MA), que habitan en localidades menores de 100 000 habitantes. MATERIAL Y MÉTODOS: Análisis transversal de la Encuesta Nacional de Salud y Nutrición 100k (Ensanut 100k) 2018 en 767 mujeres de 12 a 49 años residentes en localidades con menos de 100 000 habitantes que tuvieron su último hijo dos años anteriores a la encuesta. Se calcularon coberturas de atención a partir de modelos de regresión logística. RESULTADOS: Las mujeres con MA tienen menor cobertura continua en salud materna que las que no tuvieron MA (8.1 y 19.6%, respectivamente). La cobertura de atención del infante con contenido adecuado fue menor a 30% y no hubo diferencias entre los grupos. CONCLUSIONES: Es necesario fortalecer acciones focalizadas en este grupo de mujeres para reducir brechas en las coberturas y mejorar la salud materno-infantil.

Overall user satisfaction with family planning services and associated quality care factors: a cross-sectional analysis.

BACKGROUND: Studies of user satisfaction with family planning services (FPSs) have been conducted in different countries, and have been employed to identify ways of improving health, reducing costs and implementing reforms. The present work is the first-ever study undertaken in Mexico on the subject. Our objective was to identify how overall user satisfaction with FPSs in Mexico was related to: healthcare logistics, the functional value of services and the quality of interpersonal relations. METHODS: Users of 18 public clinics were surveyed in 2015. Data collected referred to their past and present use of FPSs, as well as to their perceptions of the services provided. We built a logistic regression model with potentially influential variables in order to assess their association with overall satisfaction. RESULTS: According to the self-reports of the 722 users interviewed, the following factors were decisive in their overall satisfaction with services: receiving sufficient information during visits (OR = 3.38; 95% CI:1.88-6.06), feeling that their opinions were taken into consideration by clinic staff (OR = 2.58; 95% CI:1.14-5.85), feeling that the motives for their visits were addressed (OR = 2.71; 95% CI:1.29-5.71), being assigned enough time for consultation (OR = 2.35; 95% CI:1.26-4.37), having the opportunity to ask questions and clarify doubts (OR = 2.31; 95% CI:1.21-4.43), experiencing no or few interruptions during their medical consultations (OR = 1.97;95% CI:1.10-3.51), and feeling satisfied with the contraceptive method provided (OR = 1.79; 95% CI:1.03-3.11). CONCLUSIONS: Service providers must be kept well informed on the perspective of users concerning user expectations. Taking into account the cultural context and perceived needs of users while providing service would improve the quality of care and, hence, the overall satisfaction of users.

Indications for Cesarean Delivery in Mexico: Evaluation of Appropriate Use and Justification.

BACKGROUND: Cesarean delivery is one of the most widely used surgical interventions in Latin America and in many cases it is performed with no clear medical indication. Our objective was to analyze the relationship between reported indications for a cesarean and support for that indication in the clinical record in four Mexican hospitals, during the 2006-2007 period. METHODS: The data are from 604 (37.1%) women from a total of 1,625 who were admitted to the hospital in labor, and who gave birth through cesarean. Multivariate logistical regression analysis was used to explore the association between indications for clinically justified or unjustified surgery and other clinical and sociodemographic variables. RESULTS: Supporting clinical information for indications of cesarean delivery were found in only 45 percent of the cases considered. The adjusted statistical analysis showed that the variables associated with an unjustified indication for cesarean were: not having had a prior birth (OR 1.84 [95% CI 1.16-2.89]), having a maximum cervical dilation of 4 centimeters or less at time of cesarean (OR 2.44 [95% CI 1.53-3.87]), and having received care in a private hospital (OR 6.11 [95% CI 1.90-19.57]). DISCUSSION: The indications for cesarean related to labor dynamics were those least supported. Not having had a prior birth poses the greatest risk of having a poorly supported indication for a cesarean delivery. It would be prudent to institute audits, and greater requirements for and surveillance of documentation for cesarean delivery indications.

[Knowledge about pregnancy risk and self-efficacy in adolescent males: parental support and school factors]. / Conocimientos sobre riesgo de embarazo y autoeficacia en hombres adolescentes: apoyo parental y factores escolares.

OBJECTIVE: To identify the association between knowledge about pregnancy risk and self-efficacy in condom use with parental support and school factors in adolescent men. MATERIALS AND METHODS: Cross-sectional study with 448 students in Puebla and Morelos. Two logistic models were adjusted. RESULTS: Knowledge about pregnancy risk is associated with communication about sexuality between parents and sons (OR = 2.45, 95%CI 1.35-4.47), satisfaction with school (OR=2.18, 95%CI 1.15-4.13), if teachers talk about gender equity frequently/very frequently (OR=1.69, 95%CI 1.06-2.67) and with age (OR=1.77, 95%CI 1.26-2.50). Self-efficacy in condom use is statistical related with communication about sexuality between parents and sons (OR=1.80, 95%CI 1.01-3.20), satisfaction with school (OR=2.60, 95%CI 1.42-4.77), belong to middle socioeconomic level (OR=1.82, 95%CI 1.07-3.11) and live in a community with a high degree of marginalization (OR=0.47, 95%CI 0.30-0.73). CONCLUSIONS: To study family and school support, considering the influence of the social environment, allows a greater understanding of skills acquisition for a preventive sexual behavior, in males during early adolescence.

OBJETIVO: Identificar la asociación entre conocimiento sobre riesgo de embarazo y autoeficacia en el uso del condón, con el apoyo parental y factores escolares, en hombres. MATERIAL Y MÉTODOS: Estudio transversal con 448 estudiantes en Puebla y Morelos. Se ajustaron dos modelos logísticos. RESULTADOS: Los conocimientos sobre riesgo de embarazo se asocian con el que los padres hablen sobre sexualidad (RM=2.45, IC95% 1.35-4.47), con el agrado por asistir a la escuela (RM=2.18, IC95% 1.15-4.13), con el que los profesores hablen frecuentemente/muy frecuentemente sobre equidad de género (RM=1.69, IC95% 1.06-2.67) y con la edad (RM=1.77, IC95%1.26-2.50). La autoeficacia en el uso de condón se relaciona con el que los padres hablen sobre sexualidad (RM=1.80, IC95% 1.01-3.20), con el agrado por asistir a la escuela (RM=2.60, IC95% 1.42-4.77), con el nivel socioeconómico medio (RM=1.82, IC95% 1.07-3.11) y con alto grado de marginación (RM=0.47, IC95% 0.30-0.73). CONCLUSIONES: Estudiar el apoyo familiar y escolar, considerando la influencia del entorno social, permite mayor entendimiento de la adquisición de habilidades para una conducta sexual preventiva en hombres durante la adolescencia temprana.

[Teen pregnancy and educational gaps: Analysis of a national survey in Mexico]. / Embarazo adolescente y rezago educativo: análisis de una encuesta nacional en México.

OBJECTIVE: To characterize female adolescents who have been pregnant, and to analyze the association between adolescent pregnancy and educational gaps. MATERIALS AND METHODS: A cross-sectional study was conducted. Data come from the Encuesta Nacional de Salud y Nutrición (Ensanut 2012), a Mexican representative survey. The set of data used is related to sociodemographic and reproductive characteristics from 1 790 women from 12 to 19 years who had begun their sexual life and had a pregnancy record. Three statistical models were adjusted to observe the association between variables. The dependent variable of the first model was the condition of previous pregnancy, the second to be pregnant at the time of data collection, and the third, educational gap. RESULTS: A 74.9% of the adolescents with history of pregnancy has educational gap. To have the condition of previous pregnancy is associated with living with sexual partner (OR=8.4), educational gap (OR=2.4), low socioeconomical level (OR=2.0) and school assistance (OR=0.5). To be pregnant at the time of data collection has related only to living with sexual partner (OR=9.4). The educational gap shows an association with having more than one pregnancy (OR=2.4), live with sexual partner (OR=1.6), low socioeconomical level (OR=1.8), and school assistance as protective factor (OR=0.3). CONCLUSION: It is necessary to implement effective and efficient educational public politics in order to decrease educational gap. At the same time, to guarantee and improve sexual education in the school system to prevent adolescent pregnancy.

[Between contradictions and risks: Mexican male adolescents' views about teenage pregnancy and its association with sexual behavior]. / Entre contradicciones y riesgos: opiniones de varones adolescentes mexicanos sobre el embarazo temprano y su asociación con el comportamiento sexual.

OBJECTIVE: To explore the opinions of Mexican male adolescents regarding teenage pregnancy and analyze its association with sexual behavior. MATERIALS AND METHODS: This is a cross-sectional study using a self-administered questionnaire among a conventional sample of male students (15-19 years old) in eight public schools in Morelos and Mexico City. Analyses include multivariate models to identify the association between opinions and sexual behaviors. RESULTS: Overall, 68% agree that a teenage pregnancy is a negative event. In a hypothetical case, if a girlfriend got pregnant in this moment 56% would continue in the school whereas 18% would definitely abandon it. Those who affirm that a teenage pregnancy is something very bad have greater odds of using condoms (OR=1.8; p<0.05). CONCLUSIONS: Male adolescents' views about teenage pregnancy are associated with some sexual behaviors; however their opinions reflect several contradictions. The design of surveys directed exclusively to explore male adolescents' opinions about reproductive health is urgent.

[Coverage for birth care in Mexico and its interpretation within the context of maternal mortality]. / Cobertura de atención del parto en México. Su interpretación en el contexto de la mortalidad materna.

OBJECTIVE: To evaluate health coverage for birth care in Mexico within the frame of maternal mortality reduction. MATERIALS AND METHODS: Two information sources were used: 1) The comparison between the results yield by the Mexican National Health and Nutrition Surveys 2006 and 2012 (ENSANUT 2006 and 2012), and 2) the databases monitoring maternal deaths during 2012 (up to December 26), and live births (LB) in Mexico as estimated by the Mexican National Population Council (Conapo). RESULTS: The national coverage for birth care by medical units is nearly 94.4% at the national level, but in some federal entities such as Chiapas (60.5%), Nayarit (87.8%), Guerrero (91.2%), Durango (92.5%), Oaxaca (92.6%), and Puebla (93.4%), coverage remains below the national average. In women belonging to any social security system (eg. IMSS, IMSS Oportunidades, ISSSTE), coverage is almost 99%, whereas in those affiliated to the Mexican Popular Health Insurance (which depends directly from the Federal Ministry of Health), coverage reached 92.9%. In terms of Maternal Mortality Ratio (MMR), there are still large disparities among federal states in Mexico, with a national average of 47.0 per 100 000 LB (preliminary data for 2012, up to December 26). The MMR estimation has been updated using the most recent population projections. CONCLUSION: There is no correlation between the level of institutional birth care and the MMR in Mexico. It is thus necessary not only to guarantee universal birth care by health professionals, but also to provide obstetric care by qualified personnel in functional health services networks, to strengthen the quality of obstetric care, family planning programs, and to promote the implementation of new and innovative health policies that include intersectoral actions and human rights-based approaches targeted to reduce the enormous social inequity still prevailing in Mexico.

[Sociodemographic and reproductive characteristics associated with the increase of cesarean section practice in Mexico]. / Características sociodemográficas y reproductivas asociadas con el aumento de cesáreas en México.

OBJECTIVE: To describe the trend of cesarean section practice in Mexico, and its association with women's sociodemographic and reproductive characteristics. MATERIALS AND METHODS: Based on the 2000, 2006 and 2012 National Health Surveys, information on c-section was analyzed. A multivariate logistic regression model was used in 2012. RESULTS: A 50.3% increase in the use of c-section was observed nationally from 2000 to 2012. Women more likely to undergo a c-section include those whose delivery care takes place in the private sector (OR=2.84, 95%CI:2.15-3.74). When associating women's age and parity, the greatest risks are observed among primiparous women between 12 and 19 years of age, and those aged 35 years and more (OR=6.02, 95%CI:1.24-29.26 and OR=5.20, 95%CI:2.41-11.21, respectively). CONCLUSIONS: Some recommendations to revert the increase of this clinical practice, especially when there is no full justification for its realization, are proposed.

Continuum of care for maternal, newborn and child health: Evidence from a national survey in Mexico.

OBJECTIVE: To compare coverage of maternal, newborn and child health (MNCH) continuum of care between women who had experienced adolescent maternity (AM) and those who had not. METHODS: Using a Mexican probabilistic survey representative at the national level (ENSANUT 2018-19), we developed a cross-sectional analysis of 1,768 women aged 12 to 49 years who had a child within five years before the interview. We used modified Poisson models to estimate prevalence ratios (PRs) and independent and conditional coverage levels based on the probability estimates yielded by these models at different stages of maternal-newborn care process. RESULTS: PRs for the MNCH continuum of care were approximately 40% lower for women who had experienced AM compared to those who had not (95%CI:0.35, 1.14). The coverage for the MNCH continuum of care was only 7.4% [95%CI: 3.5, 11.2] and 11.7% [95%CI: 9.3, 14.1] in women who had/not experienced AM, respectively. CONCLUSIONS: The provision of a continuum of care for mothers and their children can be achieved through a combination of well-defined policies and strategies that improve health care practices and services throughout the life cycle. It is necessary to expand the coverage and quality of care, which will provide the opportunity to shift the focus from vertical programs to integrated continuous care. Policy makers must implement interventions that are consistent with specific problems of population and health-care providers. Our analysis highlights the deficiencies in the care process, making this study a useful reference for countries with similar characteristics.
