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.

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.

Al menos un tercio de los adultos mexicanos tiene HTA y de ellos al menos la mitad no habían sido diagnosticados. Debe evaluarse la pertinencia de los actuales programas de diagnóstico de HTA porque el subdiagnóstico y mal control pueden ocasionar complicaciones y la muerte.

[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.

Se presentaron las prevalencias más altas en >40-50 años y en las mujeres. No hubo diferencia por nivel socioeconómico. En el periodo 2000-2018 aumentó la prevalencia de obesidad 42.2% y de obesidad mórbida 96.5%. Las mujeres con talla baja tuvieron mayor riesgo (RM=1.84) de tener obesidad que las mujeres sin esta condición, mientras que en hombres el riesgo fue menor (RM=0.79). CONCLUSIONES: En México, la prevalencia de obesidad sigue aumentando sin importar nivel socioeconómico, región o localidad.

[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.

The obesogenic environment around elementary schools: food and beverage marketing to children in two Mexican cities.

BACKGROUND: Unhealthy environments and food advertisements are major determinants of childhood obesity. Recent regulation has banned unhealthy foods from schools in Mexico. However, currently there is no regulation limiting exposure to food marketing around schools. Thus, our objective was to analyze the characteristics of food advertising practices around 60 elementary schools in two cities and to evaluate compliance with the Pan American Health Organization (PAHO) recommendations and the local food industry self-regulatory marketing code. METHODS: Data were collected during the period of October 2012 to March 2013. A random sample of elementary schools was selected from two Mexican cities. Using geographic information systems, we drew a 100-m-diameter buffer around each school. Trained personnel obtained photographs to assess the locations and types of food advertisements. Our results were stratified by school type and by indicators of compliance with the PAHO and industry recommendations. We developed a multivariate negative binomial regression model to determine factors predicting the number of advertisements around schools. RESULTS: The number of advertisements was significantly higher around public schools than around private schools (6.5 ± 5.6 vs. 2.4 ± 3.5, p < 0.05). Printed posters were the most common type of marketing medium (97%), showing mostly sugar-sweetened beverages, sweet breads, candies, and bottled water. Promotions, such as special prices or gifts, were included on 30% of printed posters. Food advertising practices were often in compliance with industry recommendations (83%) but not with those from the PAHO (32%) (p < 0.001). CONCLUSION: Our results support the importance of monitoring the obesogenic environment and identifying policy tools to protect children from food marketing not only inside schools but also around them, particularly in lower income communities.

[Hypertension in Mexican adults: prevalence, diagnosis and type of treatment. Ensanut MC 2016.] / Hipertensión arterial en adultos mexicanos: prevalencia, diagnóstico y tipo de tratamiento. Ensanut MC 2016.

OBJECTIVE: To describe the prevalence, awareness and proportion of adults with an adequate control of hypertension. MATERIALS AND METHODS: Blood pressure was measured at 8 352 adults who participated in the Ensanut MC 2016. The adults who reported having diagnosis of hypertension or had systolic blood pressure values (TAS) ≥140mmHg or diastolic blood pressure (TAD) ≥90mmHg were classified as hypertensive. Hypertension was considered controlled when blood pressure was TAS <140mmHg and TAD <90mmHg. RESULTS: The prevalence of hypertension was 25.5%. Of these, 40.0% were unaware of having high blood pressure. Of the hypertensive adults who had previous diagnosis of hypertension and receiving drug treatment (79.3%), 45.6% had blood pressure under control. CONCLUSIONS: A high percentage of adults are unaware of having hypertension and nearly half have inadequate control. The relevance of current programmes for diagnosing hypertension should be assessed, as well as the effectiveness of their control strategies.

OBJETIVO: Describir la prevalencia de hipertensión arterial (HTA) en adultos, el porcentaje de ellos con diagnóstico previo y la proporción que tuvo un control adecuado. MATERIAL Y MÉTODOS: Se midió la tensión arterial a 8 352 adultos que participaron en la Ensanut MC 2016. Se clasificó como hipertensos a quienes reportaron haber recibido previamente el diagnóstico de HTA, o presentaban cifras de tensión arterial sistólica (TAS) ≥140mmHg o tensión arterial diastólica (TAD) ≥90mmHg. Se consideró tensión arterial controlada cuando la TAS <140mmHg y la TAD <90mmHg. RESULTADOS: La prevalencia de HTA en adultos fue de 25.5%, de los cuales, 40.0% desconocían tener HTA. De los hipertensos que tenían diagnóstico previo de HTA y que recibían tratamiento farmacológico (79.3%), 45.6% tuvo tensión arterial bajo control. CONCLUSIONES: Un alto porcentaje de adultos desconocen tener HTA y de ellos casi la mitad tiene un control inadecuado. Debería evaluarse la pertinencia de los actuales programas de diagnóstico de HTA y la efectividad de sus estrategias de control.

Vitamin D deficiency is common and is associated with overweight in Mexican children aged 1-11 years.

OBJECTIVE: To assess vitamin D dietary sources, intake and 25-hydroxyvitamin D status and their association with individual and sociodemographic characteristics in Mexican children. DESIGN: Data obtained from 2695 children aged 1-11 years from the Mexican National Health and Nutrition Survey (2012) were analysed. Diet was assessed by a 141-item FFQ. 25-Hydroxyvitamin D was measured by a chemiluminescent assay. RESULTS: Mean vitamin D intake was 3·38 (se 0·09) µg/d (135·2 (se 3·6) IU/d) among pre-school children and 2·85 (se 0·06) µg/d (114·0 (se 2·4) IU/d) in school-age children. Milk accounted for 64·4 % of vitamin D intake in pre-school children and 54·7 % in school-age children. Vitamin D deficiency (serum 25-hydroxyvitamin D<50 nmol/l) was 25·9 % in pre-schoolers and 36·6 % in school-age children. Overweight/obese school-age children had a higher risk of vitamin D deficiency compared with normal-weight children (OR=2·23; 95 % CI 1·36, 3·66; P<0·05). CONCLUSIONS: Vitamin D intakes are low in Mexican children, and milk is the main source of the vitamin. Vitamin D deficiency is common and associated with overweight in school-age children.

Usual Intake of Added Sugars and Saturated Fats Is High while Dietary Fiber Is Low in the Mexican Population.

BACKGROUND: The Mexican National Health and Nutrition Survey (ENSANUT) was carried out in 2012. Information from the survey is used to design and evaluate food and nutrition policies in Mexico. OBJECTIVE: The objective of this study was to estimate the usual intake of energy and macronutrients in the Mexican population by using the ENSANUT 2012. METHODS: Twenty-four-hour recall interviews were administered to a nationally representative subsample of 10,096 individuals aged ≥1 y from the ENSANUT 2012. Usual intake distributions and the prevalence of inadequate intakes were estimated by using the Iowa State University method. Student's t tests and tests on the equality of proportions were used to compare usual intakes and prevalence of inadequacy across socioeconomic status, area (rural or urban), and region of residence (North, Center, or South). RESULTS: Energy and macronutrient intakes and indicators of dietary adequacy are presented for children (ages 1-4 y and 5-11 y), adolescents (12-19 y), and adults (≥20 y). At the national level, the estimated mean fiber intake was below the Adequate Intake for all population subgroups, suggesting inadequacies. The estimated proportion with a usual added sugars intake of >10% of total energy intake was >64% in all age groups. The proportion with a usual saturated fat intake of >10% of total energy intake was estimated to be >78% in children, >66% in adolescents, and >50% in adults. Overall, fiber intake was lower and intakes of saturated fat and added sugars were higher in urban compared with rural areas, in the North compared with South regions, and among those with high compared with low socioeconomic status (P < 0.05). CONCLUSIONS: Fiber intake is lower and added sugar and saturated fat intakes are higher than recommended for >50% of the Mexican population aged ≥1 y. These results highlight the importance of improving the diets of the overall population to reduce the risk of noncommunicable chronic diseases.

Usual Vitamin Intakes by Mexican Populations.

BACKGROUND: In the past several years, the consumption of high-energy, nutrient-poor foods has increased globally. Dietary intake data collected by the National Health and Nutrition Survey (ENSANUT) 2012 provide information to assess the quality of the Mexican diet and to guide food and nutrition policy. OBJECTIVE: The aim was to describe the usual intake and the prevalence of inadequate intakes of vitamins for the overall Mexican population and by subgroups defined by sex, age, region, urban or rural areas, and socioeconomic status (SES). METHODS: ENSANUT 2012 is a cross-sectional probabilistic survey representative of the Mexican population. Dietary information was collected by using the 24-h recall automated multiple-pass method (n = 10,096) with a repeated measurement on a subsample (n = 889) to permit adjustment for intraindividual variability with the use of the Iowa State University method. Mean usual intakes and the prevalence of inadequate intakes of thiamin, riboflavin, niacin, folate, and vitamins A, D, E, C, B-6, and B-12 were calculated for children aged 1-4 y (CH1-4y), children aged 5-11 y (CH5-11y), adolescents aged 12-19 y, and adults aged ≥20 y. RESULTS: In all of the age groups, prevalences of inadequate intakes of vitamins D and E were the highest (77-99% of adults and adolescents and 53-95% of CH5-11y and CH1-4y) and those of folate and vitamin A were intermediate (47-70% of adults and adolescents, 15-23% of CH5-11y and 8-13% of CH1-4y), whereas those of thiamin, riboflavin, niacin, and vitamins B-6, B-12, and C were the lowest (0-37% of adults, 1-27% of adolescents, and 0-2.4% of CH5-11y and CH1-4y). With few exceptions, the highest prevalences of inadequate intakes for vitamins were observed in the poorest populations (rural South region and the lowest tertile of SES). CONCLUSIONS: The intake of vitamins among Mexicans is inadequate overall. Information collected by ENSANUT can help target food assistance programs and develop strategies to prevent vitamin deficiencies.

Usual Dietary Energy Density Distribution Is Positively Associated with Excess Body Weight in Mexican Children.

BACKGROUND: Studies suggest a positive association between dietary energy density (DED) and body weight in adults, but evidence in children is inconclusive. OBJECTIVE: The objective of this study was to compare usual DED distributions of nonoverweight vs. overweight or obese (OW/O) Mexican children. METHODS: The study used 24-h recall (24HR) data from 2367 children aged 5-11 y from the 2012 Mexican National Health and Nutrition Survey (ENSANUT 2012). Repeated 24HR measures were obtained in a random sample (∼10%) to estimate usual intake distributions by using the Iowa State University (PC-Side) method. Implausible dietary reports were identified. Multivariate linear regression models were used to evaluate the relation between DED and body mass index status and to compare results with and without PC-Side adjustment and restriction to plausible reporters. RESULTS: A total of 35.1% of the children in the sample were OW/O. The usual DED mean was ∼175 kcal/100 g in both the complete sample and the plausible reporters subsample. Regression models adjusted by PC-Side and for potential confounders showed higher DED in OW/O relative to nonoverweight children for both plausible reporters (9.7 kcal/100 g; n = 1452, P < 0.0001) and the complete sample (7.9 kcal/100 g; n = 2367, P < 0.0001). The DED difference in plausible reporters translates into 88 additional kilocalories in daily energy intake of OW/O children. In the absence of PC-side adjustment, the difference was significant for plausible reporters (P < 0.05) but not for the complete sample (P > 0.10). CONCLUSIONS: A positive association between usual DED and OW/O was found in Mexican children. The association was stronger when only plausible reporters were considered. This suggests that there is a need for strategies to reduce energy density in the diet of Mexican children.

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.

[Prevalence of obesity in Mexican adults 2000-2012]. / Prevalencia de obesidad en adultos mexicanos, 2000-2012.

OBJECTIVE: To describe the prevalence of overweight and obesity in Mexican adults ≥20 y of age, as well as to describe its trends in the last three Mexican health surveys. MATERIALS AND METHODS: A sample of 38 208 adults with anthropometric's. The classification to categorize body mass index (BMI) was the World health Organization's (WHO). To define abdominal obesity classification was used the International Diabetes Federation (IDF) data. RESULTS: The prevalence of overweight and obesity was 71.3% (overweight 38.8% and obesity 32.4%). The prevalence of abdominal adiposity was 74.0%, being higher in women (82.8%) than in men (64.5%). Over the past 12 years the mean annualized BMI percent increase was 1.3%. This increase was higher in the 2000-2006 (1%) than in the 2006-2012 (0.3%) period. CONCLUSION: In spite of the deacceleration of the increasing prevalence, there is no evidence to infer that prevalences will decrease in the next years. Thus, public policies for obestiy prevention and control should be strengthened and improved.

[Hypertension: prevalence, early diagnosis, control and trends in Mexican adults]. / Hipertensión arterial: prevalencia, diagnóstico oportuno, control y tendencias en adultos mexicanos.

OBJECTIVE: The present study aims to describe the prevalence, distribution and trends of hypertension (HT) in Mexican adults ≥20 years, and to describe the prevalence of early diagnosis and treatment of HT. MATERIALS AND METHODS: A total of 10 898 adults were considered. The measurement of blood pressure was performed following the procedures recommended by the American Heart Association. An adult was considered, hypertensive when he met the diagnostic criteria of JNC-7. RESULTS: The prevalence of HT was 31.5%, of which 47.3% were unaware of their condition. Pharmacological treatment was not associated with a higher percentage of subjects under control. CONCLUSION: Prevalences from 2000, 2006 and 2012 suggest that there is a stabilization. A health problem of this magnitude requires better diagnosis, care and training of the medical sector so that appropriate treatments are prescribed and HT control can be enhanced.

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.

Food acculturation drives dietary differences among Mexicans, Mexican Americans, and Non-Hispanic Whites.

Our aim was to examine the effects of food acculturation on Mexican Americans' (MA) diets, taking the Mexican diet as reference. We used nationally representative samples of children (2-11 y) and female adolescents and adults (12-49 y) from the Mexican National Nutrition Survey 1999 and NHANES 1999-2006 to compare the diets of Mexicans (n = 5678), MA born in Mexico (MAMX) (n = 1488), MA born in the United States (MAUS) (n = 3654), and non-Hispanic white Americans (NH-White) (n = 5473). One 24-h diet recall was used to examine the percentage consuming and percentage energy consumed from selected food groups. Most of the food groups analyzed displayed a fairly linear increase or decrease in percent energy/capita intake in this order: Mexican, MAMX, MAUS, NH-White. However, few significant differences were observed among the US subpopulations, especially among MAUS and NH-Whites. Overall, compared to Mexicans, the US subpopulations had greater intakes of saturated fat, sugar, dessert and salty snacks, pizza and French fries, low-fat meat and fish, high-fiber bread, and low-fat milk, as well as decreased intakes of corn tortillas, low-fiber bread, high-fat milk, and Mexican fast food. Furthermore, the patterns were similar in all age groups. Although we found a mix of positive and negative aspects of food acculturation, the overall proportion of energy obtained from unhealthy foods was higher among the US subpopulations. Our findings indicate that within one generation in the US, the influence of the Mexican diet is almost lost. In addition, our results reinforce the need to discourage critical unhealthful components of the American diet among MA.

Caloric beverage consumption patterns in Mexican children.

BACKGROUND: Mexico has seen a very steep increase in child obesity level. Little is known about caloric beverage intake in this country as well as all other countries outside a few high income countries. This study examines overall patterns and trends in all caloric beverages from two nationally representative surveys from Mexico. METHODS: The two nationally representative dietary intake surveys (1999 and 2006) from Mexico are used to study caloric beverage intake in 17, 215 children. The volume (ml) and caloric energy (kcal) contributed by all beverages consumed by the sample subjects were measured. Results are weighted to be nationally representative. RESULTS: The trends from the dietary intake surveys showed very large increases in caloric beverages among pre-school and school children. The contribution of whole milk and sugar-sweetened juices was an important finding. Mexican pre-school children consumed 27.8% of their energy from caloric beverages in 2006 and school children consumed 20.7% of their energy from caloric beverages during the same time. The three major categories of beverage intake are whole milk, fruit juice with various sugar and water combinations and carbonated and noncarbonated sugared-beverages. CONCLUSION: The Mexican government, greatly concerned about obesity, has identified the large increase in caloric beverages from whole milk, juices and soft drinks as a key target and is initiating major changes to address this problem. They have already used the data to shift 20 million persons in their welfare and feeding programs from whole to 1.5% fat milk and in a year will shift to nonfat milk. They are using these data to revise school beverage policies and national regulations and taxation policies related to an array of less healthful caloric beverages.

Hypertension in Mexican adults: results from the National Health and Nutrition Survey 2006.

OBJECTIVE: To describe the prevalence of hypertension among Mexican adults, and to compare to that observed among Mexican-Americans living in the US. MATERIAL AND METHOD: The primary data source came from adults (>20 years) sampled (n=33366) in the Mexican National Health and Nutrition Survey 2006 (ENSANUT 2006). Hypertension was defined when systolic blood pressure was >or=140 and/or diastolic was >or= 90 or patients previously diagnosed. RESULTS: A total of 43.2% of participants were classified as having hypertension. We found a positive statistically significant association (p<0.05) between hypertension and BMI, abdominal obesity, previous diagnosis of diabetes and hypercholesterolemia. Subjects with hypertension had a significantly higher odd of having a history of diabetes or hypercholesterolemia. Hypertension had a higher prevalence in Mexico than among Mexican-Americans living in the US. CONCLUSIONS: Hypertension is one of the most prevalent chronic diseases in Mexico. In the last six years in Mexico, a substantial increase (25%) has been observed in contrast to the reduction seen among Mexican-Americans (-15%).
