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.

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.

[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.

OBJETIVO: Analizar la evolución de la prevalencia de con-ductas alimentarias de riesgo (CAR) en adolescentes mexi-canos entre 2006 y 2018. 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.

[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.

[Use of contraception and family planning in adolescent and adult women in Mexico]. / Inicio de vida sexual, uso de anticonceptivos y planificación familiar en mujeres adolescentes y adultas en México.

OBJECTIVE: To offer current evidence about age at sexual initiation and contraceptive use among adolescent and adult women of different age groups, places of residence, and marital status in Mexico. MATERIALS AND METHODS: Data were analyzed from ENSANUT 2006 and 2012 surveys on knowledge and use of contraceptives. RESULTS: In 2012 31.2% of 15-19 year old adolescent women had undergone sexual debut. Condom use increased from 31.8% in 2006 to 47.8% in 2012. Women in rural areas reported lower levels of contraceptive use at last sexual intercourse; 47.9% of 30-34 year-old and 53.2% of 35-49 year-old women reported not using any contraception at last sexual intercourse. A high percentage of women did not adopt contraception after the most recent obstetric event: 52% (15-19 years), 44.2% (20-29 years), 42.5% (30-34 years) and 39% (≥35 years)]. CONCLUSIONS: Equitable policies to promote contraception, particularly after a post-obstetric event, are needed.

[Vaccination coverage in young, middle age and elderly adults in Mexico]. / Cobertura de vacunación en adultos y adultos mayores en México.

OBJECTIVE: To estimate vaccination coverage in adults 20 years of age and older. MATERIALS AND METHODS: Analysis of data obtained from the National Health and Nutrition Survey 2012. RESULTS: Among adults 20-59 years old coverage with complete scheme, measles and rubella (MR) and tetanus toxoid and diphtheria toxoid (Td) was 44.7,49. and 67.3%, respectively. Coverage and percentage of vaccination were significantly higher among women than men. Among women 20-49 years coverages with complete scheme, MR and Td were 48.3, 53.2 and 69.8%, respectively. Among adults 60-64 years old, coverage with complete scheme, Td and influenza vaccine were 46.5, 66.2 and 56.0%, respectively. Among adults >65 years coverages for complete scheme, Td, influenza vaccine and pneumococcal vaccine were 44.0, 69.0, 63.3 and 62.0%, respectively. CONCLUSION: Vaccination coverage among adult population as obtained from vaccination card or self-report is below optimal values although data may be underestimated. Recommendations for improvements are proposed.

Association of socioeconomic status, problem behaviors, and disordered eating in Mexican adolescents: results of the Mexican National Health and Nutrition Survey 2006.

PURPOSE: To explore the association of socioeconomic status (SES) with disordered eating behaviors (DEB) in Mexican adolescents, and the coexistence of DEB and other problem behaviors. METHODS: Information about adolescents (10-19 years) was retrieved from the Mexican National Health and Nutrition Survey 2006 database. Associations were evaluated through ordinal regression. RESULTS: Higher SES was associated with DEB (odds ratio [OR]: 2.05, 95% confidence interval [CI]: 1.52-2.75). Use of tobacco (OR: 2.10, 95% CI: 1.58-2.81), alcohol (OR: 2.03, 95% CI: 1.51-2.56), and suicide intent (OR: 5.13, 95% CI: 3.46-7.60) were associated with DEB. CONCLUSION: DEB were more frequent among adolescents from higher SES households. The lack of association between SES and DEB reported by other studies might be because of the lack of variability in samples. The association of DEB and other problem behaviors highlights the importance of an integral approach to teenagers' mental health.

Lead blood concentrations and renal function evaluation: study in an exposed Mexican population.

The relation of blood Pb concentrations and renal dysfunction has been reported in association with interstitial fibrosis, tubular atrophy, and decreased glomerular filtration. In this report information about blood Pb concentrations and renal function tests in a population from Oaxaca, Mexico is analyzed. The main changes found were that males had higher blood Pb concentrations than females (P<0.0012); the leading variables associated with this were occupation (glazed pottery workers, P=0.0001) and the use of glazed pottery for preparing meals (P=0.0000). Variables that better explain uric acid variability were blood Pb concentrations, sex, weight, and height (r2=0.23). Hyperuricemia was associated with blood Pb concentrations above 40 microg/dL (OR=1.74, 95% CI, 1.12-2.61). SCr was associated with sex, age, and blood Pb, with coefficient r2=0.12. Our findings might be related to inadequate control of oven emissions, a situation that will require further analysis and the implementation of preventive measurements for the nonoccupational exposed population.

[Profile of sexual behavior in 12- to 19-year-old Mexican adolescents. Results of ENSA 2000]. / Perfil del comportamiento sexual en adolescentes mexicanos de 12 a 19 años de edad. Resultados de la ENSA 2000.

OBJECTIVE: To describe traits associated with sexual behaviors in Mexican adolescents, their knowledge about contraception, and factors associated with pregnancy and utilization of contraceptives during first sexual intercourse. MATERIAL AND METHODS: Data from the Mexican National Health Survey 2000 (ENSA 2000) were analyzed. This study, conducted between September 1999 and March 2000, was a complex survey with a probabilistic, stratified, and cluster sampling design. The sample population included 15 241 adolescents 12 to 19 years of age. Data analysis included descriptive statistics and a chi-squared test for differences of proportions; also, logistic regression was used to obtain odds ratios. RESULTS: A total of 69.2% adolescents reported knowledge of at least one contraception method; 16.4% of subjects reported having had sexual intercourse. Males initiated sexual intercourse earlier than females and only 37% of all adolescents utilized contraceptives during their first sexual intercourse. Logistic regression analysis showed that being male, having a higher education, having knowledge of at least one contraception method, and having initiated sexual intercourse at an older age, were factors associated with utilization of a contraception method in their first sexual intercourse. A total of 55.7% of sexually active female adolescents had been pregnant. Pregnancy among adolescents was associated with low educational level, sexual activity at early age, and to have sometime lived in free union. CONCLUSIONS: The majority of sexually active adolescents did not use contraception during their first sexual intercourse, rendering them at risk of unwanted pregnancies.

Perfil del comportamiento sexual en adolescentes mexicanos de 12 a 19 años de edad: resultados de la ENSA 2000 / Profile of sexual behavior in 12 to 19 year-old Mexican adolescents: results of ENSA 2000

OBJETIVO: Describir las características del comportamiento sexual de los adolescentes mexicanos, su grado de conocimiento sobre anticoncepción, las variables que se relacionan con la utilización de anticonceptivos en la primera relación sexual y las que se asocian con el embarazo. MATERIAL Y MÉTODOS: Se analizó la base de datos de adolescentes de la Encuesta Nacional de Salud 2000, realizada en septiembre de 1999 a marzo de 2000, la cual tuvo un diseño complejo al ser probabilístico, polietápico, estratificado y por conglomerados. La muestra incluyó a adolescentes de entre 12 a 19 años de edad (n=15 241). Se hizo un análisis descriptivo, se aplicó la prueba ji cuadrada (Wald) para evaluar diferencias de proporciones, y se construyeron dos modelos de regresión logística para obtener razones de momios. RESULTADOS: El 69.2 por ciento de los adolescentes refirió conocer al menos un método de control de la fecundidad. El 16.4 por ciento mencionó haber tenido relaciones sexuales, y los hombres iniciaron la actividad sexual antes que las mujeres; es importante mencionar que tan sólo 37 por ciento de los adolescentes usaron algún método anticonceptivo en la primera relación sexual. El análisis de regresión logística mostró que los adolescentes del sexo masculino, los de mayor escolaridad, quienes poseían información de algún método anticonceptivo y aquellos que inician esta actividad a una edad mayor tuvieron más probabilidad de usar anticonceptivos en su primera relación sexual. El 55.7 por ciento de las mujeres que mencionaron haber iniciado actividad sexual han estado embarazadas. El embarazo en las adolescentes se asoció significativamente con un nivel bajo de escolaridad, con iniciar su vida sexual a edades tempranas y con el hecho de haber estado alguna vez unidas. Conclusiones. En general, la población adolescente que ha tenido relaciones sexuales no utilizó métodos anticonceptivos durante su primera relación, lo cual incrementa la posibilidad de embarazos.
