Pre-Gestational Obesity and Gestational Weight Gain as Predictors of Childhood Obesity.

OBJECTIVE: To evaluate the associations of pre-gestational body mass index (BMI) and gestational weight gain (GWG) with the risks of overweight, obesity, and adiposity in the first seven years of life in the offspring of a cohort of pregnant women. METHODS: Analysis of 751 mothers and their children participating in the PROGRESS cohort. These women were recruited in Mexico City between 2007 and 2010. Pre-gestational BMI was classified as normal, overweight, and obesity according to the WHO. GWG was calculated as the difference between the last reported pre-pregnancy weight and the pre-gestational weight and categorized as inadequate, adequate, or excessive, according to US IOM recommendations. Children's anthropometry was evaluated at 4-5 and 6-7 years of age. Adiposity was classified into three groups: normal (BMI z-score and waist circumference), overweight (BMI z-score>1), and overweight plus abdominal obesity (OW+AO). A generalized structural equation model (GSEM) was constructed to account for the temporal relationship between variables and to assess direct and indirect effects. RESULTS: A total of 49.3% of the women had excessive (13.8 ± 4.2 kg) and 19.8% inadequate (3.15 ± 3.4 kg) GWG. Women with pre-gestational overweight or obesity were more likely to have excessive GWG (OR 1.9 [95% CI: 1.32, 2.74] and 3.50 [95% CI: 1.83, 6.69], respectively). In the GSEM, excessive GWG was directly associated with OW+AO at 4-5 years. At 6-7 years, pre-gestational obesity was associated with OW+AO. CONCLUSION: Pre-gestational obesity and excessive GWG were independent predictors of childhood obesity.

Prevalencia de obesidad y factores de riesgo asociados en adultos mexicanos: resultados de la Ensanut 2022.

OBJETIVO: Describir la prevalencia de obesidad en adultos, medida a través del índice de masa corporal (IMC) y la circunferencia de cintura (CC), estratificando por factores de riesgo y comorbilidades. Material y métodos. Se analizó la información de 8 563 participantes en la Encuesta Nacional de Salud y Nutrición 2022 (Ensanut 2022). Se clasificó la obesidad por IMC y por CC. Se calcularon razones de momios (RM) para asociar la obesidad con factores de riesgo y diagnóstico de comorbilidades. RESULTADOS: La prevalencia de sobrepeso fue 38.3%, obesidad 36.9% y obesidad abdominal (OA) 81.0%. Las mujeres tuvieron una mayor RM (1.4) de tener obesidad y OA (2.5). Los adultos con obesidad tenían una mayor posibilidad de tener diagnóstico de diabetes (RM 1.7), hipertensión (3.6) y dislipidemia (RM 2.3) que los adultos con IMC normal. CONCLUSIONES: La prevalencia de obesidad en adultos mexicanos es una de las más altas a nivel mundial y está asociada con los factores de riesgo y enfermedades crónicas más frecuentes. Se requieren políticas públicas multisectoriales para prevenir y controlar la obesidad.

Prevalencia, tratamiento y control de la hipertensión arterial en adultos mexicanos: resultados de la Ensanut 2022.

OBJETIVO: Describir la prevalencia de hipertensión arterial (HTA), las características del tratamiento y la proporción de adultos mexicanos que tiene tensión arterial (TA) controlada. Material y métodos. Se midió la TA a 8 647 adultos en la Encuesta Nacional de Salud y Nutrición 2022 (Ensanut 2022). Se consideró que un participante tenía HTA o TA controlada cuando cumplía los criterios de la American College of Cardiology y la American Heart Association (ACC/AHA) o la Eighth Joint National Committee (JNC-8). RESULTADOS: La prevalencia de HTA en adultos fue 47.8% (según criterio del ACC/AHA). De éstos, 65.5% desconocía su diagnóstico. En adultos con diagnóstico previo de HTA, 33.7% tuvo TA controlada. Según la clasificación JNC-8, 29.4% de los adultos tenía HTA y 43.9% ignoraba su diagnóstico. Conclusión. En la Ensanut 2022 la mitad de los adultos tenía HTA y de ellos, tres de cada cinco no habían sido diagnosticados. El sistema de salud debe mejorar sus mecanismos de detección de HTA porque el subdiagnóstico y el mal control de la TA ocasiona discapacidad, mala calidad de vida y mortalidad prematura.

Trends in overweight and obesity in children under 24 months of age in Mexico (2012-2020): analysis of four national health surveys.

The prevalence of childhood obesity has increased rapidly in Mexico, with significant consequences for the population's health in the future. Little is known about the prevalence of obesity in children under two years of age, even though this life stage is fundamental to prevent this condition. This study aims to determine the magnitude, distribution, and trends of overweight and obesity in children under 24 months of age using the Mexican National Health and Nutrition Surveys (ENSANUT) conducted in the last 10 years. The data presented here are derived from four ENSANUTs, carried out in Mexico in 2012, 2016, 2018, and 2020. They include 6,719 infants under 24 months with complete anthropometric data (weight/height) by age, gender, Indigeneity, area of residence, and socioeconomic status. The risk of overweight levels and overweight + obesity rates were calculated according to World Health Organization guidelines. We identified that infants < 12 months currently have a higher prevalence of overweight + obesity (10.3%) and that those aged 12 to 23 months are generally at a higher risk of overweight (26.1%). The most relevant findings of this study, linking weight trends to sex, region, socioeconomic status, and indigeneity, show that overweight and obesity prevalences vary across the Mexican population, without presenting a specific behavior. There is a high prevalence of overweight and obesity among Mexican infants and a slight trend toward increased obesity in infants < 12 months. Weight monitoring and obesity prevention interventions focused on the first 1,000 days of life are essential.

Resumen: La prevalencia de la obesidad infantil ha aumentado rápidamente en México, y tiene consecuencias para la salud de la población en el futuro. Poco se sabe sobre la prevalencia de obesidad en niños que tienen menos de dos años, etapa fundamental para la prevención de esta condición. El objetivo fue determinar la magnitud, la distribución y las tendencias de sobrepeso y obesidad en niños menores de 24 meses de edad utilizando las Encuestas Nacionales de Salud y Nutrición (ENSANUT) en México en los últimos 10 años. Los datos presentados se derivan de cuatro ENSANUTs en México: 2012, 2016, 2018 y 2020. Los datos incluyen 6.719 menores de 24 meses de edad con datos antropométricos completos (peso/altura) por edad, sexo, etnicidad, lugar de residencia y nivel socioeconómico. Se calculó el riesgo de sobrepeso y sobrepeso + obesidad siguiendo las directrices de la Organización Mundial de la Salud. Se identificó que los menores de 12 meses tienen una prevalencia más alta de sobrepeso + obesidad (10,3%), y los que tienen entre 12 y 23 meses tienen riesgo de sobrepeso más alto (26,1%). Los hallazgos más relevantes por sexo, región, nivel socioeconómico y etnicidad de este estudio que las prevalencias de sobrepeso y obesidad varían en la población mexicana, sin presentar un comportamiento específico. Hay una alta prevalencia de sobrepeso y obesidad en niños mexicanos, y una ligera tendencia de aumento de obesidad en menores de 12 meses. El monitoreo del peso y las intervenciones de prevención de obesidad centradas en los primeros 1.000 días de vida son esenciales.

Abstract: Objective: To describe the prevalence of hypertension in Mexican adults, the proportion with controlled blood pressure (BP), and the trend in the 2018-2020 period. Materials and methods: BP was measured in 9 844 adults who participated in the National Health and Nutrition Survey (Ensanut, in Spanish) 2020. They were considered to have hypertension or BP controlled when adults met the Seventh Joint National Committee (JNC-7) or American Heart Association (AHA) criteria. Results: The prevalence of hypertension was 49.4% (according to AHA), of which 70.0% were unaware of their diagnosis. When using JNC-7 criteria, 30.2% of the adults had hypertension and 51.0% were unaware of your diagnosis. Among adults with a previous diagnosis of hypertension, 54.9% had controlled BP. Between the 2018-2020 period, no changes in prevalences were observed. Conclusions: At least a third of Mexican adults have hypertension and of them, at least half have not been diagnosed. The relevance of current hypertension diagnostic programs should be evaluated because underdiagnosis and poor control can lead to complications and death.

Screen-Based Sedentary Behaviors and Their Association With Metabolic Syndrome Components Among Adults in Mexico.

INTRODUCTION: Approximately 25% of the adult population worldwide and 49.8% of Mexican adults have metabolic syndrome. Metabolic syndrome is the result of unhealthy dietary and sleeping patterns, sedentary behaviors, and physical inactivity. The objective of our study was to evaluate the association between sedentary behaviors as screen-based sedentary time (SBST) and each component of metabolic syndrome among adults who participated in the Mexico National Survey of Health and Nutrition Mid-way 2016. METHODS: We analyzed sociodemographic, clinical, and physical activity data from 3,166 adults aged 20 years or older. The International Physical Activity Questionnaire was used to evaluate sedentary behavior. SBST was obtained by counting minutes per week spent watching television, playing video games, and interacting with computers and smartphones. We used Poisson regression to estimate the prevalence ratio of time in front of screens as a continuous variable and its association with metabolic syndrome. RESULTS: The mean (SD) hours per day of SBST in men was 3.6 (0.4) and in women was 2.8 (0.2). The prevalence of metabolic syndrome was 59.6%. In men, the risk for metabolic syndrome increased 4% (P < .05) for each hour of SBST. Similarly, for each hour of SBST, the risk of abdominal obesity increased by 4% (P < .01). In women, we observed that the risk of hypertension or high-density lipoprotein cholesterol deficiency increased for each hour of SBST, and the risk of abdominal obesity increased for each hour of SBST in those who were inactive. CONCLUSION: Sedentary behavior based on screen time is associated with metabolic syndrome and its components among Mexicans, depending on hours of sleep. Current public health policies should consider strategies for reducing SBST.

Case-Control Analysis of the Impact of Anemia on Quality of Life in Patients with Cancer: A Qca Study Analysis.

Anemia is a common condition in cancer patients and is associated with a wide variety of symptoms that impair quality of life (QoL). However, exactly how anemia affects QoL in cancer patients is unclear because of the inconsistencies in its definition in previous reports. We aimed to examine the clinical impact of anemia on the QoL of cancer patients using specific questionnaires. We performed a post-hoc analysis of a multicenter, prospective, case-control study. We included patients with cancer with (cases) or without (controls) anemia. Participants completed the European Organization for Research and Treatment of Cancer Quality of Life questionnaire version 3.0 (EORTC QLQ-C30) and Euro QoL 5-dimension 3-level (EQ-5D-3L) questionnaire. Statistically significant and clinically relevant differences in the global health status were examined. From 2015 to 2018, 365 patients were included (90 cases and 275 controls). We found minimally important differences in global health status according to the EORTC QLQ-C30 questionnaire (case vs. controls: 45.6 vs. 58%, respectively; mean difference: -12.4, p < 0.001). Regarding symptoms, cancer patients with anemia had more pronounced symptoms in six out of nine scales in comparison with those without anemia. In conclusion, cancer patients with anemia had a worse QoL both clinically and statistically.

Validity assessment of self-reported weight and its correction process among Mexican adult women of reproductive age.

OBJECTIVE: We aimed to evaluate the agreement between self-reported weight (SRW) and measured weight (MW) in adult women of reproductive age, identify characteristics associated with the difference between SRW and MW (DW), and develop a correction procedure for SRW. METHODS: We used data from 3,452 non-pregnant or non-lactating adult women who participated in the Mexican Family Life Survey. Standardized personnel asked women about their weight before measuring weight and height. We conducted a Bland-Altman analysis for agreement and adjusted linear regression models for sociodemographic characteristics. RESULTS: Mean DW was -0.59±3.21 kg. Difference varied according to Body Mass Index (BMI) and region of residence (p< 0.05). Correction model for log-MW, included the log-SRW, age group (18-34 and 35-49 years), interaction term (age × SRW), log-height, Southern region, and living with a partner. Based on self-reported weight, we observed an overestimation of underweight/normal weight prevalence and an underestimation of overweight or obesity prevalence. CONCLUSION: SRW has limitations to be considered as an alternative to MW among women of reproductive age with specific characteristics. Our proposed correction equation may decrease SRW imprecision improving the estimation of overweight and obesity. We suggest that studies consider and adjust the possible bias associated with weight misreporting on health outcomes.

Correlation between short-term air pollution exposure and unprovoked lung embolism. Prospective observational (Contamina-TEP Group).

BACKGROUND: The aim was to analyze the temporal relationship between short-term air pollution exposure and acute symptomatic unprovoked pulmonary embolism (PE). PATIENTS/METHODS: We performed a prospective, multicenter study in consecutive patients diagnosed with acute symptomatic unprovoked PE from February 2012 to January 2013. We analyzed demographic and clinical data, patients' addresses, meteorological and air pollutants data (PM10, SO2, CO, NO2, ozone emission data). We considered the number of days the patient had symptoms, and the study period constituted the previous 30 days. Likewise, the mean annual data of the reference season were calculated as well as the data of the 30-day study period corresponding to the same dates in the previous 3 years in order to obtain the monthly mean of the different pollutants for each period. RESULTS: A total of 162 patients with acute symptomatic PE were recruited (43.2% unprovoked PE). The air pollutants could be determined in 50% of the patients with unprovoked PE, and a final analysis was performed in 35 patients. In the multiple comparison analysis to verify a possible correlation between the study period and the annual median, only NO2 showed a statistically significant association (p = 0.009). When comparing the study period with the previous 3 years, only NO2 maintained a statistically significant association for the 3 study periods. CONCLUSIONS: We found a relationship between short-term exposure to NO2 and the presence of unprovoked PE.

[Obesity in Mexico, prevalence andtrends in adults. Ensanut 2018-19.] / Obesidad en México, prevalencia y tendencias en adultos. Ensanut 2018-19.

OBJECTIVE: To describe the prevalence of obesity in Mexican adults stratifying by physical and sociodemographic conditions and to analyze trends. MATERIALS AND METHODS: The data of 16 256 adults who participated in Ensanut 2018-19 was analyzed. Obesity (WHO), abdominal adiposity (IFD) and short stature (NOM-008-SSA3-2017) were classified. Logistic regression models were performed to analyze the association between obesity and risk factors. ENSA-2000 and Ensanut (2006, 2012, 2018-19) were used to assess trends. RESULTS: The prevalence of overweight was 39.1%, obesity 36.1%, and abdominal adiposity 81.6%. Adults >40-50y and women had the highest prevalence. There was no difference by socio-economic level. Between 2000-2018, the prevalence of obesity increased 42.2% and morbid obesity 96.5%. Women with short stature had a higher risk (RM=1.84) of being obese than women without this condition, while in men the risk was lower (RM=0.79). CONCLUSIONS: In Mexico the prevalence of obesity continues to increase regardless of socio-economic level, region or locality.

[Prevalence, diagnosis and control of hypertension in Mexican adults with vulnerable condition. Results of the Ensanut 100k]. / Prevalencia, diagnóstico y control de hipertensión arterial en adultos mexicanos en condición de vulnerabilidad. Resultados de la Ensanut 100k.

OBJECTIVE: To describe the prevalence of hypertension (HBP) in adults with vulnerability, the percentage of them with previous diagnosis and the proportion that had adequate control. MATERIALS AND METHODS: Blood pressure was measured in 7 838 adults who participated in the Ensanut 100k. Those who self-reported the diagnosis of HBP or had systolic blood pressure (SBP) ≥130mmHg or diastolic blood pressure (DBP) ≥80mmHg were classified as hypertensive. Controlled blood pressure was considered when SBP was <130mmHg and TAD <80mmHg. RESULTS: The prevalence of hypertension in adults with a vulnerability condition was 49.2%, of which 54.7% did not know had hypertension. Of the hypertensive patients who received pharmacological treatment (69.0%), 66.8% of them had blood pressure under control. CONCLUSIONS: Almost half of Mexican adults in vulnerable condition have HBP and of these more than half do not know that they have this disease. One third of hypertensive adults have inadequate control.

OBJETIVO: Describir la prevalencia de hipertensión arterial (HTA) en adultos en condición de vulnerabilidad, el porcentaje de ellos con diagnóstico previo y la proporción con control adecuado. MATERIAL Y MÉTODOS: Se midió la tensión arterial a 7 838 adultos participantes en la Ensanut 100k. Se clasificó como hipertensos a quienes autorreportaron el diagnóstico de HTA o presentaban tensión arterial sistólica (TAS) ≥130mmHg o tensión arterial diastólica (TAD) ≥80mmHg. Se consideró tensión arterial controlada cuando la TAS fue <130mmHg y la TAD <80mmHg. RESULTADOS: La prevalencia de HTA en adultos en condición de vulnerabilidad fue de 49.2%, de los cuales 54.7% desconocía tener HTA. De los hipertensos que recibían tratamiento farmacológico (69.0%), el 66.8% tuvo tensión arterial controlada. CONCLUSIONES: Casi la mitad de los adultos mexicanos en condición de vulnerabilidad tiene HTA y de ellos, más de la mitad desconoce que tiene esta enfermedad. Asimismo, un tercio de los adultos hipertensos tiene un inadecuado control de su enfermedad.

[Overweight and obesity in Mexican vulnerable population. Results of Ensanut 100k]. / Sobrepeso y obesidad en población mexicana en condición de vulnerabilidad. Resultados de la Ensanut 100k.

OBJECTIVE: Describe the prevalences and trends of overweight and obesity in population with social vulnerability and resident of localities with <100 thousand inhabitants. MATERIALS AND METHODS: In preschoolers, schoolchildren, adolescents and adults participants of the Ensanut 100k and Ensanut 2012, sociodemographic information and anthropometry was analyzed to stimate the prevalence and trends of overweight+obesity (Ow+O), obesity and abdominal obesity. RESULTS: In preschool children the prevalence of Ow+O was 6%. In school children, adolescents and adults the prevalence of obesity was 15.3, 14.2 and 33.6%, respectively. In preschools with severe food insecurity, the prevalence of Ow+O decreased 35% between 2012-2018. In schoolchildren without program food aid, the prevalence of obesity increase 97% between 2012-2018. In adolescents without program food aid, the prevalence of obesity increase 60% between 2012-2018. In adults with moderate food insecurity, abdominal obesity increased 10% between 2012-2018. CONCLUSIONS: There is a high prevalence of obesity in Mexican population with social limitations and seems to reach the rest of the population quickly but with significant structural disadvantage.

OBJETIVO: Describir las prevalencias y tendencias de sobrepeso y obesidad en población con mayor vulnerabilidad social, residente en localidades con menos de 100 000 habitantes. MATERIAL Y MÉTODOS: En preescolares, escolares, adolescentes y adultos de la Ensanut 100k y Ensanut 2012 se analizó la información sociodemográfica y de antropometría para calcular prevalencias y tendencias de sobrepeso+obesidad (SP+O), obesidad y obesidad abdomina. RESULTADOS: La prevalencia de SP+O fue 6% en preescolares. La prevalencia de obesidad fue 15.3% en escolares, 14.2% en adolescentes y 33.6% en adultos. En comparación con el año 2012, el SP+O disminuyó 35% en 2018 entre los preescolares con inseguridad alimentaria severa. En escolares, la obesidad aumentó 97% entre 2012 y 2018 en quienes no tenían ayuda alimentaria. En adolescentes sin programas de ayuda alimentaria, la obesidad aumentó 60% entre 2012 y 2018. En adultos, entre 2012-2018 incrementó 10% la obesidad abdominal en quienes tenían inseguridad alimentaria moderada. CONCLUSIONES: Existe una alta prevalencia de obesidad en la población mexicana con vulnerabilidad social y parece alcanzar al resto de la población de forma rápida pero con importantes desventajas estructurales.

En adultos, entre 2012-2018 incrementó 10% la obesidad abdominal en quienes tenían inseguridad alimentaria moderada. Conclusiones: Existe una alta prevalencia de obesidad en la población mexicana con vulnerabilidad social y parece alcanzar al resto de la población de forma rápida pero con importantes desventajas estructurales.

Abstract: Objective: Describe the prevalences and trends of overweight and obesity in population with social vulnerability and resident of localities with <100 thousand inhabitants. Materials and methods: In preschoolers, schoolchildren, adolescents and adults participants of the Ensanut 100k and Ensanut 2012, sociodemographic information and anthropometry was analyzed to stimate the prevalence and trends of overweight+obesity (Ow+O), obesity and abdominal obesity. Results: In preschool children the prevalence of Ow+O was 6%. In school children, adolescents and adults the prevalence of obesity was 15.3, 14.2 and 33.6%, respectively. In preschools with severe food insecurity, the prevalence of Ow+O decreased 35% between 2012-2018. In schoolchildren without program food aid, the prevalence of obesity increase 97% between 2012-2018. In adolescents without program food aid, the prevalence of obesity increase 60% between 2012-2018. In adults with moderate food insecurity, abdominal obesity increased 10% between 2012-2018. Conclusions: There is a high prevalence of obesity in Mexican population with social limitations and seems to reach the rest of the population quickly but with significant structural disadvantages.

Prevalencia, diagnóstico y control de hipertensión arterial en adultos mexicanos en condición de vulnerabilidad. Resultados de la Ensanut 100k / Prevalence, diagnosis and control of hypertension in Mexican adults with vulnerable condition. Results of the Ensanut 100k

Resumen: Objetivo: Describir la prevalencia de hipertensión arterial (HTA) en adultos en condición de vulnerabilidad, el porcentaje de ellos con diagnóstico previo y la proporción con control adecuado. Material y métodos: Se midió la tensión arterial a 7 838 adultos participantes en la Ensanut 100k. Se clasificó como hipertensos a quienes autorreportaron el diagnóstico de HTA o presentaban tensión arterial sistólica (TAS) ≥130mmHg o tensión arterial diastólica (TAD) ≥80mmHg. Se consideró tensión arterial controlada cuando la TAS fue <130mmHg y la TAD <80mmHg. Resultados: La prevalencia de HTA en adultos en condición de vulnerabilidad fue de 49.2%, de los cuales 54.7% desconocía tener HTA. De los hipertensos que recibían tratamiento farmacológico (69.0%), el 66.8% tuvo tensión arterial controlada. Conclusiones: Casi la mitad de los adultos mexicanos en condición de vulnerabilidad tiene HTA y de ellos, más de la mitad desconoce que tiene esta enfermedad. Asimismo, un tercio de los adultos hipertensos tiene un inadecuado control de su enfermedad.

Abstract: Objective: To describe the prevalence of hypertension (HBP) in adults with vulnerability, the percentage of them with previous diagnosis and the proportion that had adequate control. Materials and methods: Blood pressure was measured in 7 838 adults who participated in the Ensanut 100k. Those who self-reported the diagnosis of HBP or had systolic blood pressure (SBP) ≥130mmHg or diastolic blood pressure (DBP) ≥80mmHg were classified as hypertensive. Controlled blood pressure was considered when SBP was <130mmHg and TAD <80mmHg. Results: The prevalence of hypertension in adults with a vulnerability condition was 49.2%, of which 54.7% did not know had hypertension. Of the hypertensive patients who received pharmacological treatment (69.0%), 66.8% of them had blood pressure under control. Conclusions: Almost half of Mexican adults in vulnerable condition have HBP and of these more than half do not know that they have this disease. One third of hypertensive adults have inadequate control.

La alfabetización en salud como factor clave en el autocuidado de la dieta en personas con diabetes mellitus tipo 2 / Health literacy as a key factor in diet self-care in patients with type 2 diabetes mellitus

Resumen Introducción: Alfabetización en Salud (AS) es un término que proviene del inglés health literacy, se refiere al conjunto de habilidades sociales y cognitivas que determinan la capacidad de una persona para acceder, entender y utilizar la información de forma que le permita mantener un buen estado de salud. Objetivo: Determinar la asociación entre AS y las conductas de autocuidado en personas con diabetes mellitus tipo 2. Materiales y métodos: Estudio cuantitativo, transversal y analítico llevado a cabo en dos centros de salud de atención primaria de la ciudad de Xalapa, Veracruz, México entre agosto-noviembre de 2016. La AS se midió con el European Health Literacy Survey (HLS-EU-Q47) y las conductas de autocuidado con el Summary of Diabetes Self-care Activities (SDSCA) de Toobert y Glasgow. Se eligieron 90 personas con diabetes mellitus tipo 2 que acudían a consulta. La participación fue voluntaria y previa firma de consentimiento informado. Resultados: El autocuidado de la dieta mostró asociación con la AS en su dimensión de promoción de la salud (p=0,018). Conclusiones: La AS se relaciona con las conductas de autocuidado, en específico de la dieta; a medida que aumenta la AS mejora el autocuidado.

Abstract Introduction: Health literacy refers to the set of social and cognitive skills that define the person's ability to access, understand and utilize information in such a way that a healthy condition can be maintained. Objective: To determine the association between AS and self-care behaviors in patients with type 2 diabetes mellitus. Materials and methods: A quantitative, cross-sectional and analytical study carried out in two primary health care centers in the city of Xalapa, Veracruz-Mexico, from August to November 2016. The AS was measured through the European Health Literacy Survey (HLS-EU-Q47) and the self-care behaviors were assessed using the Summary of Diabetes Self-care Activities (SDSCA) by Toobert and Glasgow. We chose 90 people with type 2 diabetes mellitus who attended consultation at the health care centers. Although their participation was voluntary, participants were required to sign the informed consent form. Results: Diet self-care was associated with AS, in a health promotion context (p=0.018). Conclusions: AS is directly related to self-care behaviors, specifically to diet.
