RESUMO

Introduction: Obesity (OB), type 2 diabetes mellitus (T2D), and hypertension (HTN) are health issues in Mexico linked to unhealthy behaviors. This study investigates the relationship between behavior change indicators and metabolic control in Mexican adults with OB, T2D, and HTN. Methods: We used data from the 2016 National Health and Nutrition Survey Midway (ENSANUT MC-2016), representing ∼59.5 million Mexican adults aged 20-59 with these conditions. We assessed behavior change indicators, including stages of change, self-efficacy, and perceptions of benefits and barriers. In addition, we conducted descriptive analyses and used statistical tests, such as Pearson's chi-squared test and logistic regression models, adjusted for multiple variables. Results: We found that adults in the action and maintenance stages of physical activity (PA) were four times more likely to have adequate HTN control than those in the precontemplation stage. Self-efficacy for PA was related to better control in T2D and HTN. Self-efficacy for reducing the consumption of sugary beverages was positively associated with control in OB and T2D. No significant association was observed with self-efficacy for consuming fruits and vegetables. Conclusion: Behavior-change indicators are significantly linked to metabolic control in adults with HTN. These results support the importance of these indicators in managing chronic diseases such as HTN and their potential use in public health strategies.

RESUMO

PURPOSE: Neoadjuvant chemotherapy in muscle-invasive bladder cancer (MIBC) patients has proven beneficial in overall survival. However, the optimal regimen is still a matter of debate. MATERIALS AND METHODS: In this retrospective analysis, we evaluate the results obtained in 42 patients treated in our center with 4 cycles of neoadjuvant dose-dense methotrexate, vinblastine, doxorubicin, and cisplatin (dd-MVAC) followed by radical cystectomy from August 2015 to October 2020. All patients had cT2 or higher non-metastatic MIBC. Clinical and pathological outcomes are reported. RESULTS: Of the 42 patients, 90.5% were men (n = 38) and the mean age was 65 years. All of them had ECOG 0-1 at diagnosis and most tumors had an initial clinical stage T2N0 (76%). Thirty-six patients (85.7%) completed 4 cycles of neoadjuvant treatment, and 21.4% required a dose reduction. The most frequent adverse event (AE) was grade 1-2 asthenia (81%), while neutropenia was the most frequent grade 3 or higher AE (38%). Complete pathological response (ypT0, ypN0) was achieved in 50% of patients (n = 21), and down-staging was observed in 57.1% (n = 24). Only one patient presented radiological progressive disease during neoadjuvant treatment (2.4%), and after a mean follow-up time of 31.5 months, 33.3% of patients experienced disease recurrence. CONCLUSIONS: Neoadjuvant chemotherapy with 4 cycles of dd-MVAC is an effective regimen with high rates of pathological complete responses and down-staging along with an acceptable toxicity profile. DD-MVAC should be considered as an alternative to cisplatin and gemcitabine in patients with good clinical performance status.

RESUMO

OBJETIVO: Analizar los cambios en la carga de la enfermedad del VIH de 1990-2017 y la influencia de las políticas y programas implementadas para su prevención y control. Material y métodos. Se elaboró una línea de tiempo de políticas e intervenciones en México; mediante modelos de regresión JoinPoint, se analizó su relación con los cambios ocurridos en las tendencias de la carga de la enfermedad del VIH. RESULTADOS: Los cambios en la carga de enfermedad se relacionan con la universalización del acceso a los medicamentos antirretrovirales (ARV), programas de atención integral y el combate al estigma y la discriminación. En el periodo analizado se observa descenso de la mortalidad relacionado con el acceso universal y gratuito a los ARV. La magnitud de los cambios tiende a ser mayor en los hombres que en las mujeres. CONCLUSIONES: Las políticas y programas implementados para tratar a las personas con VIH/Sida en México se integraron en estrategias cada vez más cohesionadas y eficaces.

RESUMO

OBJECTIVE: To present the development of a training model called AMBAR (Atención a la mujer embarazada y al recién nacido [Care for pregnant women and newborns]), which was designed to improve the quality of attention of health personnel responsible for obstetric care. MATERIALS AND METHODS: AMBAR was designed based on the results of a qualitative study exploring public health providers' needs and experiences. It was implemented in three health networks, and a total of 339 health personnel participated. RESULTS: The educational design of the course was appealing to the trained personnel, and the inclusion of simulations in all modules encouraged interest, participation, as well as the integration of new knowledge and skills into practice. CONCLUSION: AMBAR can promote better practices and increase the quality of birth care. With the proper support and willingness of staff and management, AMBAR can be implemented in all health services, both public and private.

RESUMO

Background: The World Health Organization (WHO) reports an increasing unjustified use of antibiotics in the treatment of Acute Respiratory Infections (ARI) and Acute Diarrheal Diseases (ADD) in children under five years of age. This has generated problems such as polypharmacy and the inappropriate use of antibiotics; characterized by incorrect dosage, use in viral infections, prescription inconsistent with clinical guidelines. Objective: To analyze the prescription of antibiotics, their diagnostic-therapeutic congruence, as well as the correct filling of the medical prescription, in a tertiary level hospital in Mexico. Material and methods: Observational, descriptive cross-sectional study. The electronic medical prescriptions made during the period January-December 2017 with a clinical diagnosis of ARI and EDA were analyzed. Results: Of a total of 21,446 boys and girls under five years of age, 10,233 prescriptions were issued for the treatment of ARI and ADD diagnoses. 80% of the prescriptions complied with the items indicated in the electronic file. Conclusions: The prescription of antibiotics showed a prudent use of antibiotics both in the management of acute diarrheal diseases and in the management of acute respiratory diseases. Diagnostic-therapeutic congruence was found in most of the cases in the prescriptions analyzed.

RESUMO

The COVID-19 pandemic has become the greatest burden of disease worldwide and in Mexico, affecting more vulnerable groups in society, such as people with mental disorders (MD). This research aims to analyze the governance processes in the formulation of healthcare policies for people with MD in the face of the COVID-19 pandemic. An analytical qualitative study, based on semi-structured interviews with key informants in the healthcare system was conducted in 2020. The study followed the theoretical-methodological principles of the Governance Analytical Framework (GAF). The software ATLAS.ti-V.9 was used for inductive thematic analysis, classifying themes and their categories. To ensure the proper interpretation of the data, a process of triangulation among the researchers was carried out. The findings revealed that in Mexico, the federal Secretary of Health issued guidelines for mental healthcare, but there is no defined national policy. Decision-making involved multiple actors, with different strategies and scopes, depending on the type of key-actor and their level of influence. Majority of informants described a problem of implementation in which infection control policies in the psychiatric population were the same as in the general populations which decreased the percentage of access to healthcare during the pandemic, without specific measures to address this vulnerable population. The results suggest that there is a lack of specific policies and measures to address the needs of people with mental disorders during the COVID-19 pandemic in Mexico. It also highlights the importance of considering the role of different actors and their level of influence in the decision-making process.

RESUMO

OBJECTIVE: To explore the use of birth care in a Sentinel Unit. MATERIALS AND METHODS: We interviewed eight health providers and 12 female users of health services to explore the main reasons to use birth care in a Sentinel Unit. RESULTS: Findings indicate that the reasons for which health providers do not attend births were fear of legal claims by users, lack of institutional support if complications arise, lack of training, not feeling confident in obstetric care, and the lack of necessary supplies. Female users mentioned the perception of a lack of trained physicians and a lack of necessary materials and medicines. CONCLUSIONS: Despite the strengthening of the infrastructure and human resources, as well as a 24/365 model attention and the increase of health personnel in the sentinel units, there are still significant barriers in certain units to achieve compliance with coverage of quality obstetric care focused on the needs of women.

RESUMO

BACKGROUND: Estimates of the sub-national distribution of maternal disorders in Mexico beyond Maternal Mortality Ratios are scarce. Characterizing the sub-national variation of maternal disorders may make it possible to focus more on interventions and thereby reduce their occurrence in a more meaningful and sustained manner. AIM: To analyze and describe the sub-national distribution, magnitude, trends and changes in the contribution of maternal causes to women's loss of health in Mexico from 1990-2019. METHODS: Using estimates from the Global Burden of Disease (GBD) 2019 study, we describe the distribution and trends of maternal mortality ratio (MMR), mortality rate, case-fatality rate and disability-adjusted life years (DALYs) due to maternal causes, at both national and state levels. RESULTS: Between 1990 and 2019, DALYs attributable to maternal causes had decreased 59.5%, mortality 63.8%, and incidence 46.5%. However, Maternal Mortality Ratio only decreased by 33%. The case-fatality rate of maternal disorders decreased by 50% overall; although for obstructed labor and uterine rupture, it remained unchanged. Lethality showed great variation between states, with a 3 fold difference between the maximum and minimum values. CONCLUSIONS: Although mortality and incidence of maternal causes in Mexico have greatly decreased in the last 30 years, these changes mostly reflect declines in fertility. The decrease seen in case-fatality rates is driven by decreases in causes such as hypertension and hemorrhage, though for others it remained constant. Efforts should be directed at improving access to, and management of, locally frequent maternal emergencies, formulating tailor-made regional interventions for maternal health.

RESUMO

INTRODUCTION: The history of levothyroxine has been linked to advances in the treatment of thyroid disease and to date it is the standard therapy for the treatment of hypothyroidism. Bioequivalence studies are the most widely used method to demonstrate interchangeability, although controversy persists regarding the best design for this molecule declared as a narrow therapeutic index product in many countries. This study aimed to evaluate the pharmacokinetic profile of two formulations of levothyroxine to determine bioequivalence between them. METHODS: This two-period, randomized, crossover, blind study was conducted in 80 healthy volunteers, of both sexes, using a single levothyroxine dose of 600 µg with a washout period of 42 days. Blood sampling was performed at - 30 min, - 15 min, and 0 h pre-dose and 30 min, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 10, 12, 16, 24, and 48 h post-dose. RESULTS: A total of 78 subjects successfully completed both periods. There were no serious adverse events during the study and both formulations were well tolerated. Baseline correction of serum levothyroxine concentrations was performed before statistical analysis. The mean maximum plasma concentration of the test product (Levotiroxina MK®) was 57.49 ng/mL while for the reference product it reached 59.32 ng/mL. Importantly, both test and reference formulations reached maximum concentrations in plasma at about the same time. The areas under the pharmacokinetic curves with the test product showed AUC0-t of 1407.1 ng h/mL and the reference product 1394.3 ng h/mL. The bioequivalence statistical analysis showed that the 90% confidence interval (CI90%) of the ratio of test over reference formulation was within the bioequivalence margins of 90-111%. For Cmax, the test/reference ratio was 96.2% with CI90% of 91.6-100.9%, and for AUC0-t the test/reference ratio was 99.9 with CI90% of 93.3-107.0%. CONCLUSIONS: Both formulations have the same pharmacokinetic profile and are bioequivalent in the narrow therapeutic index required by some health authorities.

RESUMO

Self-help groups (SHGs) for people living with HIV (PLHIV) are organizations created by the community to provide individuals with security, affection, improved self-esteem, and a sense of belonging. However, SHGs have also been used by the government to help implement HIV control policies. This study aimed to identify the characteristics associated with the use of SHGs by PLHIV and the routes and displacement patterns adopted by users. An analytical cross-sectional study was conducted based on data collected in six Central American countries during 2012. Using a list of SHGs, a random sampling was conducted in two stages. Firstly, the SHGs were selected. Then, the selected SHGs were visited and every third user who attended the SHG was surveyed. Logistic regression models were used to identify the characteristics associated with the use of SHGs and with attending the nearest SHGs. A spatial analysis was performed to identify the routes followed by users to reach the SHGs from their home communities. We found that the characteristics significantly associated with higher odds of SHG usage were country of residence and schooling level. The average and median distances traveled by users to attend SHGs were 20 and 5 kilometers, respectively. PLHIV do not use the SHGs closest to their locality, perhaps for fear of stigma and discrimination. We recommend that research on this topic use a mixed qualitative-quantitative methodology to better understand utilization decisions, user expectations, and the degree to which these are being met.

RESUMO

INTRODUCTION: The COVID-19 pandemic has caused a global health crisis. Vaccines against this disease have demonstrated variable efficacy and safety, although effectiveness has not been evaluated. In February 2021, the Ministry of Health of Peru approved the emergency use of the inactivated SARS-CoV-2 (Vero Cell) vaccine and initiated vaccination with health personnel at the national level. The objective of the study is to determine the effectiveness of this vaccine to reduce infections, hospitalizations, and deaths due to COVID-19. METHODOLOGY: We performed a retrospective cohort study in the period from 23 February to 26 June 2021; data were obtained from the Ministry of Health (including demographic, epidemiologic, clinical, hospital, laboratory results, deaths, and both date and quantity of vaccine doses delivered). The exposed cohort were those who received one or two vaccine doses and the non-exposed were unvaccinated. The events studied were infections, hospitalizations and deaths in the cohorts. We consider a case confirmed for COVID-19 if the test result was positive for SARS-CoV-2, via PCR or antigen test. Effectiveness was measured with incidence density ratio and risk. Confounding factors were controlled using a Poisson model with robust variance. RESULTS: We enlisted 520,733 health workers, of whom 415,212 had two vaccine doses and 105,521 were unvaccinated. The median age was 40 years (IQR: 32-50), and 65.6% were female. The effectiveness of two vaccine doses fourteen days after application adjusted by age, sex, hospitalization, and antecedent of having the infection was 90.9% (95% CI: 85.5-94.2%); effectiveness to avoid death from COVID-19; 67.7% (60.1-73.8%) effectiveness to avoid hospitalizations; and 26.3% (23.8-28.6%) effectiveness to reduce the risk of infection by SARS-CoV-2 relative to the unvaccinated cohort. CONCLUSIONS: The inactivated SARS-CoV-2 (Vero Cell) vaccine used in two doses has an acceptable effectiveness against death and risk of hospitalization, whereas it has less effectiveness in preventing COVID-19 infection.

RESUMO

Resumen Antecedentes Estudios señalan que la internalización de creencias, prejuicios y actitudes existentes en la sociedad sobre las personas de la diversidad sexual afectan fuertemente su salud mental y podrían constituirse en una barrera de acceso a la ayuda psicológica y terapéutica en personas LGB. Objetivo Determinar la asociación entre los niveles de internalización de estigma sexual (ESI) en personas autoidentificadas como lesbianas, gay y bisexuales (LGB) con la presencia de malestar subjetivo, sintomatología depresiva y ansiosa, suicidalidad, y asistencia a psicoterapia. Método Un cuestionario aplicado de manera online que incluía preguntas sobre haber asistido o estar asistiendo a psicoterapia, además de escalas que evaluaban estigma sexual internalizado, malestar-bienestar subjetivo, depresión y suicidalidad fue respondido por 669 personas cisgenero autoidentificadas como lesbianas, gay y bisexuales. Resultados Los resultados muestran una asociación positiva entre el nivel de ESI en personas LGB con sus niveles de malestar subjetivo, sintomatología depresiva y ansiosa, y suicidalidad, y una asociación negativa con estar asistiendo o haber asistido a psicoterapia. Conclusiones Se discuten las implicancias de los resultados presentados para el desarrollo de intervenciones psicoterapéuticas culturalmente competentes para pacientes pertenecientes a la diversidad sexual y de género.

Abstract Background Studies indicate that the internalization of beliefs, prejudices and attitudes existing in society about sexual minorities strongly affect their mental health and could constitute a barrier to access to psychological and therapeutic support in LGB people. Objective To determine the association between levels of internalized sexual stigma (ISS) in self-identified lesbian, gay and bisexual (LGB) people with the presence of subjective distress, depressive and anxious symptoms, suicidality, and psychotherapy attendance. Methods An online questionnaire including questions on having attended or attending psychotherapy, as well as scales assessing internalized sexual stigma, subjective distress-subjective well-being, depression, and suicidality was completed by 669 cisgender self-identified lesbian, gay, and bisexual individuals. Results The results show a positive association between the level of ISS in LGB people with their levels of subjective distress, depressive and anxious symptomatology, and suicidality, and a negative association with being attending or having attended psychotherapy. Conclusions The implications of the results presented for the development of culturally competent psychotherapeutic interventions for patients belonging to sexual and gender diversity are discussed.

RESUMO

Verbal autopsies are often used to establish cause of death but can be emotionally taxing on the interviewers. We conducted focus groups with interviewers (N = 15) who collected data for verbal autopsies in Mexico in order to explore the utility of an emotional containment strategy designed to boost self-confidence and resilience. The interviewers reflected on broader cultural perspectives on illness and death and described the strategy as helpful in developing strategies to manage emotionally stressful situations and develop their confidence in their work performance. This type of intervention may be useful for field personnel who perform verbal autopsy interviews.KEY MESSAGESIn low- and middle-income countries with less reliable statistics systems, a significant proportion of deaths is not certified by a professional doctor. This complicates the registration of causes of death, which is a crucial issue for health systems. In the absence of reliable vital statistics systems, verbal autopsies (VA) offer an alternative for establishing cause of death.In response to emotional crises leading to resignations among the interviewers while testing an instrument for collecting VA, we designed an emotional containment strategy (ECS). It was specifically crafted to boost the self-confidence and resilience of participants in addition to enhancing their capacity for emotional recovery and to regain a functional state. In order to explore ECS results we conducted a qualitative cross-sectional study with four focus groups of interviewers who collected VA.The results obtained were positive, the interviewers were able to perform their work better by overcoming the emotional crisis that occurred both in them and in the people they interviewed.We recommend developing this type of intervention with all field staff performing verbal autopsy interviews, not only as a resource for emotional health, but also as a means of achieving better-quality data collection.

Los grupos de autoayuda (GAA) para personas que viven con el VIH (PVVIH) son organizaciones creadas por la comunidad para proporcionarles seguridad, afecto, mejor autoestima y un sentido de pertenencia. Sin embargo, el gobierno también ha utilizado los GAA para ayudar a implementar políticas de control del VIH. Se buscó identificar las características asociadas con el uso de GAA por PVVIH y las rutas y patrones de desplazamiento adoptados por los usuarios. Este es un estudio analítico transversal basado en datos recogidos en seis países centroamericanos en 2012. A través de una lista de GAA, se construyó un muestreo aleatorio de dos etapas. Primero, se seleccionaron los GAA. Luego, los participantes recibieron una visita, y se evaluó cada tercio de ellos. Se utilizaron modelos de regresión logística para identificar las características asociadas al uso y visitas a los GAA más cercanos a los usuarios. Se realizó un análisis espacial para identificar las rutas que los voluntarios tomaron para llegar a los GAA en sus comunidades de origen. Se constató que las características significativamente asociadas con mayores probabilidades de uso de los GAA fueron el país de residencia y la escolaridad. Las distancias medias y medianas recorridas por los usuarios para visitar los GAA fueron de 20 kilómetros y 5 kilómetros, respectivamente. Las PVVIH no utilizan los GAA más cercanos a su casa, tal vez por miedo al estigma y a la discriminación. Se necesitan investigaciones sobre este tema que utilicen una metodología mixta cualitativa-cuantitativa para comprender mejor las decisiones de uso, las expectativas de los usuarios y el grado en que se están atendiendo.

Através de uma lista de GAAs, uma amostragem aleatória em dois estágios foi construída. Em primeiro lugar, os GAAs foram selecionados. Em seguida, eles foram visitados e cada terceiro de seus participantes foi avaliado. Foram utilizados modelos de regressão logística para identificar as características associadas ao uso e às visitas aos GAAs mais próximos aos usuários. Foi realizada uma análise espacial para identificar as rotas que voluntários tomavam para chegar aos GAAs em suas comunidades de origem. Verificamos que as características significativamente associadas com maiores chances de uso dos GAAs foram país de residência e escolaridade. As distâncias médias e medianas percorridas por usuários para visitar os GAAs foram de 20 quilômetros e 5 quilômetros, respectivamente. As PVHIV não utilizam os GAAs mais próximos de onde moram, talvez por medo de estigma e discriminação. Recomendamos que as pesquisas sobre este tema utilizem uma metodologia qualitativa-quantitativa mista para entender melhor as decisões de utilização, as expectativas dos usuários e o grau em que eles estão sendo atendidos.

RESUMO

In the last decade, Venezuela suffers a humanitarian crisis, leading to massive emigration. One of the most vulnerable migrants´ groups is pregnant women. We analyzed the perinatal outcomes of Venezuelan migrants in Colombia and identified if migration was associated with perinatal outcomes. Birth data were obtained from the 2017 Colombian national birth registry (1085 births in migrants and 654,829 in Colombians). Logistic and linear regression models were used to identify the association between the demographic, obstetric and neonatal characteristics with premature birth (PB), low birth weight (LBW), 1-min, and 5-min Apgar score. Venezuelan were more likely to have newborns with LBW, lower Apgar scores at 1-min and 5-min in comparison to Colombians. Furthermore, a difference was observed in the low health insurance coverage and antenatal care visits among Venezuelan in comparison to natives. Access to health care services for the migrants is desirable for the improvement of perinatal health conditions.

RESUMO

Chagas disease is an inflammatory, infectious disease caused by the parasite Trypanosoma cruzi found in the feces of the triatomine bug, which can cause a sudden, brief acute illness, or it may become a long-lasting chronic condition. Chagas disease is common in South America and Central America, however, the constantly expanding global community has brought Chagas disease to the forefront of non-endemic areas, particularly the United States and Europe. The authors present a case of a 47-year-old healthy farmer diagnosed with a right orbital cellulitis refractory to systemic antibiotics. Based on clinical symptoms, the patient's medical/demographical history and a proper differential diagnosis, an acute phase of Chagas disease was diagnosed. After antiparasitic treatment, the patient had a proper recovery and continued with a regular follow-up to monitor the possible development of a chronic phase.

RESUMO

BACKGROUND: According to UNAIDS, the HIV epidemic has stabilized. This as a result of increased condom use and greater access to coverage for antiretroviral therapy (ART). In Central America, civil society organizations work with self-help groups (SHGs) organized in conjunction with public health services to implement interventions seeking to increase condom use and ART adherence for people living with HIV (PLH). METHOD: To analyze the effectiveness of SHGs in Central America aimed on increasing condom use and ART adherence in PLH, We conducted a cross-sectional study using a questionnaire and a random sample of 3024 intervention group and 1166 control group. Based on propensity scoring and one-to-one matching (with replacement), we formed a comparison group to help estimate the effectiveness of the above-mentioned intervention on two outcome variables (condom use and ART adherence). The internal consistency of the results was tested through weighted least squares (WLS) and instrumental variable (IV) regression. RESULTS: Although bivariate comparisons yielded differences between intervention and control group, we found no evidence that the intervention was effective; nor did we find evidence of a heterogeneous impact among countries after adjusting for propensity scoring and the IV model. The impact observed after performing raw comparisons of the indicators may be attributable to self-selection on the part of PLH rather than to the SHGs strategy. Our results demonstrate that it is imperative to use rigorous intervention evaluation methodology to validate the consistency of results. CONCLUSIONS: The intervention had no impact on the outcome indicators measured. We recommend prioritizing the allocation of economic resources for the implementation of interventions with previously proven effectiveness. We also recommend that future studies explore why the intervention failed to produce the expected impact on condom use and ART adherence.

RESUMO

PROBLEM AND BACKGROUND: During the past two decades, Mexico has launched innovative maternal health initiatives to improve maternal and neonatal outcomes, placing emphasis on the incorporation of professional midwifery practices into the healthcare system. This study explored the perceptions of healthcare providers and women using public birth care services regarding professional midwifery practices and how can the inclusion of evidence-based midwifery techniques improve the quality of service. METHODOLOGY: We conducted a qualitative, cross-sectional study of three healthcare networks in Mexico. A content analysis was performed of data collected through 109 semi-structured interviews: 72 with healthcare providers and 37 with women. RESULTS: Healthcare providers and women had minimal knowledge of the competencies and skills of professional midwives. Medical personnel accepted the incorporation of some evidence-based midwifery practices. Women had experienced fear and anguish during childbirth so they considered that incorporating professional midwifery practices into maternal health services would be favourable in that it would render birth care more respectful. DISCUSSION AND CONCLUSIONS: Healthcare providers are willing to consider the inclusion of some evidence-based midwifery practices in health services and regard assistance from professional midwives. They believe that structural conditions will complicate their incorporation. Although the women interviewed had experienced fear, anxiety and loneliness during childbirth, most of them admitted to feeling "safer" in a hospital (secondary-care health centre) setting where possible complications could be resolved. This perception of safety served to justify the delivery of healthcare in a manner that is inattentive to women's needs, which go beyond biomedical issues and include emotions and the positive experience of childbirth.

RESUMO

OBJECTIVE: To identify differences in socioeconomic indi-cators, health conditions and use of services between the indigenous (IP) and non-indigenous population (NIP) of the country. MATERIALS AND METHODS: Descriptive cross-sectional study carried out with information obtained by the 2018-19 National Health and Nutrition Survey. RESULTS: Most IP are in the lowest socioeconomic quintile and they use less health services. Indigenous women reported a higher number of children, as well as childbirth care with midwives. IP go for medical care to institutions for the population without social security as the first option but expressed less desire to return to the same place. CONCLUSIONS: IPs use less health services. An epidemiological panorama of double burden and inequity in access indicators that affect IP is configured. Reproductive health is the area where the greatest inequali-ties are observed.

OBJETIVO: Identificar diferencias en indicadores socioeco-nómicos, de condiciones de salud y uso de servicios entre la población indígena (PI) y no indígena (PNI) del país. MATERIAL Y MÉTODOS: Estudio trasversal descriptivo con información de la Encuesta Nacional de Salud y Nutrición 2018-19. RESULTADOS: La mayoría de la PI se encuentra en el quintil socioeconómico más bajo y usa menos los servi-cios de salud. Las mujeres indígenas reportaron un mayor número de hijos, así como atención del parto con parteras. La PI acude por atención médica a las instituciones para población sin seguridad social como primera opción, pero manifiesta menor deseo de regresar a atenderse al mismo lugar. CONCLUSIONES: La PI utiliza menos los servicios de salud. Se configura un panorama epidemiológico de doble carga e inequidad en indicadores de acceso que afecta a la PI. La salud reproductiva es el ámbito donde se observan las mayores desigualdades.
