Prevalencia de conductas alimentarias de riesgo en adolescentes mexicanos: Ensanut Continua 2022.

OBJETIVO: Reportar prevalencias poblacionales actualizadas de conductas alimentarias de riesgo (CAR) con respecto a edad, sexo, condiciones de bienestar, tipo de localidad y región del país. Material y métodos. Se utilizaron los datos de adolescentes (n = 3 547) de la Encuesta Nacional de Salud y Nutrición 2022 (Ensanut 2022) obtenidos mediante el cuestionario breve de conductas alimentarias de riesgo (CBCAR) y datos sociodemográficos. Se obtuvieron prevalencias e intervalos de confianza. RESULTADOS: El 1.6% (2.0% en mujeres y 1.2% en hombres) de los adolescentes tienen riesgo de un trastorno de la conducta alimentaria, en aquéllos entre 14 y 19 años, 2.3%, en zonas urbanas 2.1%, en la región centro 2.9% y por tercer quintil de bienestar, 3.1%. Conclusión. Los datos mostrados señalan la importancia de continuar monitoreando las CAR en encuestas representativas nacionales, a diferencia de los estudios realizados en muestras no probabilísticas; la Ensanut permite contar con datos que reflejan la diversidad de la población mexicana.

Disordered eating behaviors and psychological correlates. Data from the Ensanut 2018-19

OBJECTIVE: To analyze the relationship between disordered eating behaviors (DEB) and depressive symptoms, suicide attempts, and alcohol and tobacco use in adolescents in a national survey in Mexico. MATERIALS AND METHODS: Data from the Encuesta Nacional de Salud y Nutrición 2018-19 were used. Three levels of DEB were established: no risk (DEB-NR), moderate risk (DEB-MR), and high risk (DEB-HR). An ordinal logistic regression model was performed with level of DEB risk as a dependent variable. RESULTS: National prevalence of DEB-MR was 6.0% (95%CI: 5.6, 6.5), while that of DEB-HR was 1.3% (95%CI: 1.1, 1.6). Suicide attempt (OR= 1.82, 95%CI: 1.02,3.25) and depressive symptoms (OR= 2.6, 95%CI: 1.40,4.98) were associated with being at a higher risk of DEB. CONCLUSION: Since both depressive symptoms and suicide attempt are associated with DEB, prevention strategies should consider interventions that simultaneously address the various mental health problems present in adolescence.

The Role of Effective Knowledge on Contraceptive Methods Use in the Replication of Mother-Daughter Adolescent Pregnancy in Mexico.

An important gap in the literature is the analysis of the role of effective knowledge concerning use of contraceptive methods in the intergenerational reproduction of adolescent pregnancy in low- and middle-income countries. Using data from the 2014 Mexico National Survey of Demographic Dynamics, we conducted a retrospective cohort and complete case analysis of women aged ≤ 19 years cohabitating with their mothers and who self-reported having had sexual intercourse at the moment of the survey (n = 5143). We estimated instrumental variable probit models (IV-probit) to assess the association between effective knowledge concerning the use of contraceptive methods and adolescent pregnancy. We stratified our models according to parental history of adolescent pregnancy. Adolescent pregnancy prevalence in our sample was 58.7%. The IV-probit model showed that mothers with a history of adolescent pregnancy were 12.1 percentage points more likely to have daughters who experience adolescent pregnancy. In addition, daughters with effective knowledge concerning the use of contraceptive methods were 1.3 percentage points less likely to experience an adolescent pregnancy. Our findings carry relevant implications for policies seeking to reduce adolescent pregnancy. They highlight the need for policies and programs that tackle the intergenerational transmission of sexual and reproductive behaviors by increasing the information available to adolescents and enhancing their effective knowledge about the use of contraceptive methods. Identifying population groups at higher risk of adolescent pregnancy can contribute to the design of successful reproductive health policies in Mexico and other low- and middle-income countries.

Early neurological development and nutritional status in Mexican socially deprived contexts.

Early childhood development (ECD) is a critical stage in the intergenerational process of human development. Targeted interventions depend on accurate and up-to-date ECD measurements. This paper presents estimates for the nutritional and neurodevelopmental status of socially marginalized children in Mexico. We performed a cross-sectional study based on data collected in 2019-2020 during home visits to 1,176 children aged 0-38 months across 24 highly marginalized locations in Oaxaca. We assessed nutritional status according to the World Health Organization 2006 child-growth standards and ECD status using the Child Development Evaluation Test, 2nd Edition. We stratified results by sex. Prevalence of stunting was 5.3 percentage points (p.p.) higher (p = 0.023) in males (25.3%; 95% CI: 20.2%, 31.1%) compared to females (20.0%; 95% CI: 15.0%, 26.1%). Overall prevalence rates stood at 5.7% (95% CI: 4.0%, 8.1%) for underweight, 1.5% (95% CI: 0.9%, 2.7%) for wasting and 3.6% (95% CI: 2.3%, 5.7%) for overweight/obesity, with no significant differences by sex. Prevalence of normal development was 8.3 p.p. lower (p = 0.001) in males (39.3%; 95% CI: 34.5%, 44.4%) compared to females (47.6%; 95% CI: 41.6%, 53.6%). By development area, the highest prevalence of suboptimal outcomes among children with developmental lag or at risk of delay was observed in their gross motor and language skills: 24.1% (95% CI: 20.0%, 28.8%) and 38.6% (95% CI: 34.0%, 43.3%), respectively. The largest difference between the sexes was found in the language area. Our results show that childhood development strategies have been insufficient thus far in the studied population. Programs specifically designed to prevent ECD lags and bridge inequality gaps are urgently needed. Trial registration: ClinicalTrials.gov ID: NCT04210362.

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.

[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.

OBJECTIVE: To estimate changes in the quality of process of care and its association with glycaemic control in adults with type 2 diabetes. MATERIALS AND METHODS: Changes in compliance of 14 process of care indicators for 9 038 adults with type 2 diabetes and glycaemic control in a subsample were estimated. Averages, weighted changes and associations without or controlling for other factors were estimated us-ing statistical weights for the combined data (Ensanut 2012 and Ensanut 2018-19). RESULTS: From 2012 to 2018-19, glycaemic control doubled. Early detection of complications and increased insuline use improved, but identification and treatment of cardiovascular risk factors decreased. The overall quality of care was associated with optimal glycaemic control. CONCLUSIONS: There are areas of opportunity for improvement of quality of care, that deserve comprehensive strategies and continuous monitoring.

OBJETIVO: Estimar cambios en la calidad del proceso de atención y su asociación con control glucémico en adultos con diabetes tipo 2. MATERIAL Y MÉTODOS: cambio en el cumplimiento de 14 indicadores del proceso de atención en 9 038 adultos con diabetes tipo 2 y del control glucémico en una submuestra. Se estimaron promedios, cam-bios ponderados y asociaciones crudas y ajustadas utilizando ponderaciones estadísticas para datos combinados (Ensanut 2012 y Ensanut 2018-19). RESULTADOS: De 2012 a 2018-19, el control glucémico se duplicó. Mejoró la detección tem-prana de complicaciones y aumentó el uso de insulina, pero disminuyó la identificación y tratamiento de factores de riesgo cardiovascular. La calidad global de la atención se asoció con el control glucémico óptimo. CONCLUSIONES: Existen áreas de oportunidad para la mejora de la calidad en la atención que ameritan estrategias integrales y monitorización continua.

[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.

[Disordered eating in Mexican adolescents, 2006-2018]. / Evolución de las conductas alimentarias de riesgo en adolescentes mexicanos, 2006-2018.

OBJECTIVE: To analyze the evolution in prevalence of risky eating behaviors (REB) in Mexican adolescents between 2006 and 2018. MATERIALS AND METHODS: We employed data from Ensanut 2006 and 2018-19. We evaluated REB with the Brief Questionnaire of Risky Eating Behaviors, dis-tinguishing between normative (recommended for obesity prevention) and non-normative (not recommended) REB. We analyzed the association between REB and indicators of the sociocultural environment of adolescents (socio-economic level, urban/rural place of living. RESULTS: The prevalence of normative REB changed from 11.9% (95%CI: 11.3-12.6) to 15.7% (95%CI: 15.0-16.5), and the prevalence of non-normative REB from 12.1 (95%CI: 11.4-12.9) to 21.9 (95%CI: 21.0-22.9). REB were more frequent among females, those with overweight or obesity, those in the higher so-cioeconomic levels, and in urban areas. CONCLUSIONS: REB are an important issue among adolescents, and preventive strategies are required.

MATERIAL Y MÉTODOS: Se utilizó información de las Ensanut 2006 y 2018-19. Se evaluaron las CAR con el Cuestionario Breve de Conductas Alimentarias de Riesgo, distinguiendo entre normativas (recomendadas en la prevención de la obesidad) y no normativas (no reco-mendadas). Se analizó la relación entre CAR e indicadores del medio ambiente sociocultural en que los adolescentes se desenvuelven (nivel socioeconómico, tamaño de la localidad). RESULTADOS: La prevalencia de CAR normativas pasó de 11.9% (IC95%: 11.3-12.6) a 15.7% (IC95%: 15.0-16.5) y la de las CAR no normativas de 12.1 (IC95%: 11.4-12.9) a 21.9 (IC95% 21.0-22.9). Las CAR fueron más frecuentes en mujeres, en adolescentes con sobrepeso u obesidad, de nivel socioeco-nómico más alto y en localidades urbanas. CONCLUSIONES: Las CAR son un problema importante en adolescentes y es necesario implementar estrategias de prevención.

[Inequalities in access to services, basis for policies to reduce the health gap]. / Desigualdades en el acceso a servicios, base de las políticas para la reducción de la brecha en salud.

OBJECTIVE: To estimate inequalities in access to health services among Mexican population living in localities of 100 000 or less inhabitants. MATERIALS AND METHODS: Cross-sectional analysis using the National Health and Nu- trition Survey 100k 2018 survey data. Access was estimated using health insurance and care for the last health condition. As inequality measure, we estimated the concentration index using an imputation of household per capita income. RESULTS: Among studied population, health insurance was 82.42% and access to care 60.03%. We identified inequalities in both indicators; marginal and pro-poor for insurance and pro-rich for access to care. CONCLUSIONS: In Mexico, even within the popuation living in poverty there are inequalities in access to health care. More granular public interventions are needed to address inequalities in an effective way.

OBJETIVO: Estimar la desigualdad en acceso a servicios de salud en poblaciones de localidades menores de 100 000 habitantes en México. MATERIAL Y MÉTODOS: Análisis de la Encuesta Nacional de Salud y Nutrición 100k 2018. Se estimó el acceso con base en la afiliación a un esquema de aseguramiento (acceso potencial) y la atención para el más reciente problema de salud (acceso a atención) mediante el índice de concentración, utilizando una imputación del ingreso per cápita. RESULTADOS: La afiliación a algún esquema de ase- guramiento en salud fue de 82.42% y el acceso a atención de 60.03%. Se identificaron desigualdades en ambos indicadores, marginales para acceso potencial y con mayor concentración entre la población de menor ingreso; para acceso a atención se encontró desigualdad con mayor concentración entre la población de mayor ingreso. CONCLUSIONES: En México prevalecen desigualdades en acceso a servicios de salud para la población en condiciones de pobreza. Es necesario desarrollar intervenciones públicas con mayor granularidad para incidir de forma efectiva en la desigualdad.

[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.

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.

Abstract: 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 inEncuesta 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 byEstrategia Nacional para la Prevención del Embarazo en Adolescentes(ENAPEA) targeting this population.

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

Resumen: 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. Conclusión: Es necesario fortalecer acciones focalizadas en este grupo de mujeres para reducir brechas en las coberturas y mejorar la salud materno-infantil.

Abstract: Objective: To compare the coverage of continuous maternal 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-inhabitants 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.

Multidimensional social support is associated with healthcare utilization among older Mexican adults.

In this study, we aimed to estimate the association between social support and healthcare utilization among older Mexican adults. We conducted a prospective study with 4027 older adults aged 65-74 in rural areas in seven Mexican states. Data were collected at baseline (2007) and 14 months later (2009). Healthcare utilization was defined as number of visits to a physician for preventive or curative purposes in the last 6 months. Multidimensional social support was operationalized into two components: structural (living arrangements, marital status and network size) and functional (perceived availability of support; and perceived support across emotional, instrumental, economic and information domains). Mixed-effects regression models were used to estimate the probability of healthcare use and to examine the association between social support and the number of visits to a physician. Results showed that perceived availability of social support was associated with the probability of visits to a physician (OR 1.44; p < .01). Meanwhile, the following domains of functional component of social support were associated with the probability of visits to a physician: instrumental (OR 1.55; p < .01), economic (OR 1.19; p = .03) and informational (OR 1.39; p < .01); and also with the number of visits to a physician: instrumental (e ß  = 1.27; p < .01), economic (e ß  = 1.14; p = .01) and informational (e ß  = 1.12; p < .10). Our findings suggest that a significant association exists between social support, measured from a multidimensional viewpoint, and healthcare utilization, in which greater social support was related to a greater extent of use of health services.

[Vaccination coverage in children and adolescents in Mexico: vaccinated, under vaccinated and non vaccinated]. / Cobertura de vacunación en niños y adolescentes en México: esquema completo, incompleto y no vacunación.

OBJECTIVE: To assess vaccination coverage of children and adolescents. MATERIALS AND METHODS: Study based on National Health and Nutrition Survey 2012. RESULTS: Coverage in <1 year infants olds infants was <70% for 3 vaccines and <50% for 5. In 15-23 months-olds infants coverage was 59.8% for four vaccines and 51% for six. In 6-year-olds coverage was 93.2% for 1 dose of MMR, and was below 50% for three vaccines in adolescents. Proportion of non-vaccinated individuals was 4.7% in <1-year-olds, 0.2% in 15-23-month-olds, 6.8% in 6-year-olds and 37% in adolescents. Coverage for BCG, HB, and Pneumococcal vaccines in <1-year-olds, and MMR in 15-23-month-olds was >80%. No health insurance and maternal or adolescent illiteracy were explanatory variables for incomplete schema. CONCLUSIONS: Results suggest it is necessary to strengthen information systems, health promotion, training, and daily vaccination without restrictive schedules, ensuring timely and adequate supply of vaccines.
