RESUMO
BACKGROUND: Sedentary behavior is linked to excess fat mass; however, this association may be inconclusive due to potential measurement errors in self-reported sedentary behavior. OBJECTIVE: To assess the association between changes in sedentary behavior and fat mass in a Cohort of Health Workers (HWCS) from 2004 to 2010. METHODS: A total of 1,285 adults participating in the Cohort of Health Workers were evaluated in 2004 and 2010. Fat mass (kg) was measured by dual X-ray absorptiometry. A self-administered questionnaire was used to estimate the sedentary behavior. Sedentary behavior was also estimated using accelerometry in a sample of 142 health workers. Accelerometry data were used to correct self-reported sedentary behavior using a generalized linear model, which included values for sleeping time, age, sex, sedentary behavior, glucose, and triglycerides. Concordance between both methods was assessed using a kappa and Bland-Altman analysis. Once sedentary behavior was corrected, the values were used to evaluate the association between changes in sedentary behavior and body fat mass using a fixed effect model in the cohort, adjusting for confounders. RESULTS: Self-reported sedentary behavior was 2.8 ± 1.8 and 2.3 ± 1.6 h/day, and body fat mass was 24.9 ± 8.1 and 26.8 ± 8.5 kg in 2004 and 2010, respectively. After applying the correction model, the self-reported sedentary behavior was 7.6 ± 1.2 and 7.5 ± 1.2 h/day in 2004 and 2010, respectively. For every hour increase in corrected sedentary behavior, there was an observed increase of 0.847 (p > 0.001) kg in body fat mass during the 6.8 years in the Cohort of Health Workers from 2004 to 2010. Conversely, non-corrected self-reported sedentary behavior was associated with a non-significant reduction of 0.097 kg (p = 0.228) for every hour of sedentary behavior. CONCLUSIONS: Increased sedentary behavior was associated with increased body fat mass when corrected self-reported sedentary behavior was used. Implementing public health strategies to reduce sedentary behavior is imperative.

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.

BACKGROUND: Children < 5 years of age are at risk of developing an iron deficiency due to a low intake of bioavailable iron (FeBio). Few studies have estimated dietary FeBio in children at a national level in relation to sociodemographic characteristics. This study aimed to estimate FeBio intake and its association with sociodemographic factors among Mexican children aged 12-59 months. METHODS: A cross-sectional study was carried out. Information on serum ferritin and diet was obtained from a national survey and representative sample of 1012 Mexican children aged 12-59 months. We used a 24-h recall to estimate total iron, heme and non-heme iron, vitamin C, phytates, calcium, and meat intake. We calculated FeBio intake using an algorithm. Differences in FeBio intake were analyzed by area of residence (rural/urban), country region (north, center, south), and socioeconomic status (SES), using linear regression models by age subgroups (12-23 and 24-59 months) and total population, while adjusting for study design. RESULTS: Total iron intake was 9.2 ± 6.7 mg/d. The estimated average of total FeBio fluctuated between 0.74-0.81 mg/d, with a bioavailability of 9.15-12.03% of total iron. Children aged 12-23 months residing in rural areas consumed less FeBio than those in urban areas (ß = - 0.276) (p < 0.05). Children aged 24-59 months with high SES consumed more FeBio (ß = 0.158 mg/d) than those of a low SES (p < 0.05). CONCLUSIONS: FeBio is low in Mexican preschoolers. Being from a rural area and having low SES were negatively associated with FeBio intake. These results can benefit interventions seeking to improve iron status.

OBJECTIVE: To identifiy the energy contribution (EC) of the food consumed in those older than five years and by sociodemographic characteristics in Mexican population. MATERIALS AND METHODS: We analyzed data from 24-hour recalls from 7 983 subjects ≥5 years included in the Encuesta Nacional de Salud y Nutrición 2012 (Ensanut 2012). The EC to total daily energy intake of 50 foods allocated to eight food groups at national level and stratified by age, area of residence, region and socioeconomic level was estimated. RESULTS: Seven foods contributed 50% of total energy intake: tortilla and corn products (20.6%), sweet bread (6.6%), vegetable oils (4.9%), white bread and wheat products (4.9%), carbonated sugary drinks (4.6%), red meat (4.0%) and whole milk (4.0%). Other foods, which its consumption is recommended to increase due to its positive effects on health, showed minor contributions (less than 1.0%), with the exception of beans (3.3%). Great heterogeneity in intakes was observed between subgroups of the population. CONCLUSIONS: The identification of individual foods and their EC for both, food groups whose consumption should be increased as well as those that should be reduced can be useful for the design of regulatory actions and educational strategies aimed at reducing the diet related burden of disease.
OBJETIVO: Identificar la contribución a la ingesta de energía (CIE) de alimentos consumidos en mayores de cinco años y por características sociodemográficas, en la población mexicana. MATERIAL Y MÉTODOS: Se analizó información del recordatorio de 24 horas de 7 983 sujetos ≥5 años incluidos en la Encuesta Nacional de Salud y Nutrición 2012 (Ensanut 2012). Se estimó la CIE de 50 alimentos clasificados en ocho grupos de alimentos en el ámbito nacional, estratificando por edad, área de residencia, región y nivel socioeconómico. RESULTADOS: Siete alimentos contribuyeron con 50% de la ingesta energética total: tortilla y productos de maíz (20.6%), pan dulce (6.6%), aceites vegetales (4.9%), pan blanco y derivados de trigo (4.9%), bebidas azucaradas carbonatadas (4.6%), carnes rojas (4.0%) y leche entera (4.0%). Otros alimentos, cuyo consumo es recomendable aumentar por sus efectos positivos en salud, mostraron contribuciones menores a 1.0%, con excepción del frijol (3.3%). Se observó gran heterogeneidad en el consumo entre subgrupos de población. CONCLUSIONES: La identificación de los alimentos individuales y su CIE, tanto en grupos de alimentos cuyo consumo se recomienda aumentar, como en aquéllos que se recomienda reducir, puede ser de utilidad para el diseño de acciones regulatorias y estrategias educativas dirigidas a disminuir la carga de enfermedad relacionada con la dieta.

OBJECTIVE: Childhood obesity has increased rapidly in Mexico, along with changes in the food environment. However, little is known about the dietary patterns (DP) of Mexican children. We aimed to characterize the DP of schoolchildren and to analyse their associations with sociodemographic factors. DESIGN: Cross-sectional analysis. Dietary and sociodemographic information was obtained, including a single 24 h recall, socio-economic status (SES), geographic region, area of residence and ethnicity. DP were defined with cluster analysis (using k-means). Multinomial logistic regression models, adjusted for the survey design, were used to assess associations between DP and sociodemographic variables. SETTING: 2012 Mexican National Health and Nutrition Survey (ENSANUT-2012). SUBJECTS: Schoolchildren (n 2751) aged 5-11 years who participated in ENSANUT-2012. RESULTS: Four DP were identified: 'Traditional', 'Industrialized', 'Varied' and 'Modern'. Reported energy intake (mean (sd)) was lowest in the 'Traditional' and highest in the 'Industrialized' DP (7037 (3707) kJ/d (1682 (886) kcal/d) v. 8427 (3753) kJ/d (2014 (897) kcal/d), respectively, P<0·05). Significant differences in fat and fibre intakes were seen across DP. Non-indigenous v. indigenous children were 22·0 times (95 % CI 5·1, 93·6) more likely to have a 'Modern' rather than 'Traditional' DP. Relative likelihood of having an 'Industrialized' rather than 'Traditional' DP was 6·2 (95 % CI 3·9, 9·9) among schoolchildren from high SES v. low SES. CONCLUSIONS: Among Mexican schoolchildren, DP were associated with sociodemographic variables. Non-indigenous children were significantly more likely to consume a 'Modern' than a 'Traditional' DP. Children with higher SES were more likely to have an 'Industrialized' pattern. It is necessary to consider dietary characteristics in the different sociodemographic strata when dietary interventions are designed.

OBJECTIVE: To analyze the association between dietary patterns and metabolic syndrome (MS) components in adult women with excess weight. MATERIAL AND METHODS: Cross-sectional study with anthropometric, dietary, biochemical and blood pressure data. Dietary patterns were identified by factor analysis and multiple logistic regression models were used to analyze associations. RESULTS: The prevalence of altered glucose was 14.6%, of hypertriglyceridemia 40.4%, of altered concentration of high density lipoprotein cholesterol(HDLc) 45.0%, hypertension 4.6% and MS 30%. The pattern with high consumption of corn tortillas, meats and legumes, was associated with less possibility of hyperglycemia (OR= 0.62; 95%CI 0.39-0.98). The pattern with high consumption of sweet and salty snacks, milk, rice, soaps and pasta, was inversely associated with the possibility of low HDLc concentration (OR= 0.76; 95%CI 0.60-0.97). CONCLUSIONS: A dietary pattern with greater consumption of legumes, meats and corn tortillas was associated with less possibility of having hyperglycemia.

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 â¼59.5 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.

OBJECTIVE: To describe and compare the everyday knowledge about plain water consumption among "small" and "big drinkers". MATERIALS AND METHODS: A qualitative study was conducted between April and August 2010 in Mexico. Eight focus groups with low socioeconomic status adults as key informants were conformed; half of the groups were conducted with men and half with women. Data analysis was conducted with: a) coding and categorization according to hydration literature review b) conceptual mapping, recognizing propositions and affirmations made by the participants. RESULTS: Small and big drinkers have similar everyday knowledge about plain water intake. Both groups use the same epistemological axes to explain its intake: "what the body needs". Both groups have the notion that plain water and other beverages such as soda "may be harmful" if you drink them in excess. CONCLUSIONS: Everyday knowledge about water is related to soda and drinks used to substitute water intake. The characteristics of water and soda intake are constructed based on personal experience and insights on their effect on the body and mind. These representations can be used to assess fluid intake and may constitute barriers to the consumption of plain water.

BACKGROUND: Ultraprocessed products (UPPs) have been associated with unfavorable health outcomes; however, until now, they have not been associated with the coexistence of undernutrition and overnutrition, known as the double burden of malnutrition (DBM) at the individual level. METHODS: Cross-sectional analyses were performed on data collected from children and adolescents participating in the 2006 and 2016 Mexican National Health and Nutrition Surveys. The food and beverages reported in the food frequency questionnaire (SFFQ) were classified as UPPs as defined by the NOVA classification system. Associations of UPPs with anemia, excess weight, and the DBM were estimated with logistic regression models. A pseudo-panel was generated using the cohorts of children born from 1997 to 2001 to estimate the effect of the UPPs on anemia, excess weight, and the DBM. RESULTS: The consumption of UPPs (% energy) was higher in 2016 (children 30.1% and adolescents 28.3%) than in 2006 (children 27.3% and adolescents 23.0%) in both age-groups. The higher contribution of UPPs was positively associated with excess weight and the DBM in children's lower tertile of socioeconomic status (SES) and the DBM in higher tertile of SES in adolescents. The pseudo-panel analysis shows the positive association between UPPs and DBM in lower SES. CONCLUSIONS: These results provide evidence of the association between the consumption of UPPs and the DBM and excess weight in children and adolescents.

BACKGROUND: Ultra-processed foods (UPFs) are associated with poor diet quality and chronic diseases. UPFs fall into 1 of the following 4 groups classified according to the extent and purpose of processing: group 1 is unprocessed or minimally processed foods (MPFs); group 2 is processed culinary ingredients; group 3 is processed foods; and group 4 is UPFs. OBJECTIVE: The aim of this study was to evaluate the relative validity of a semi-quantitative food frequency questionnaire (SFFQ) compared with two 24-hour dietary recalls (24DRs) `to estimate dietary intake per NOVA food group in Mexican children and adolescents. DESIGN: This study is a secondary analysis of dietary data from a subsample of children and adolescents who participated in the 2012 Mexican National Health and Nutrition Survey. PARTICIPANTS/SETTING: The study participants were 217 children (aged 5 through 11 years) and 165 adolescents (aged 12 through 19 years) with complete information for the SFFQ and two 24DRs. MAIN OUTCOME MEASURES: Daily averages of energy intake and percent of energy intake for each NOVA category were calculated using the SFFQ and two 24DRs. STATISTICAL ANALYSIS: To assess relative validity, the SFFQ was compared with two 24DRs to estimate dietary intake per NOVA food group. Mean differences, Spearman correlations, intraclass correlations coefficients (ICCs), and Bland-Altman plots for continuous variables and weighted κ for ordinal variables were calculated. RESULTS: For percentage of energy intake, ICCs in children and adolescents were moderate for MPFs (ICC = 0.47 and ICC = 0.56, respectively) and UPFs (ICC = 0.53 and ICC = 0.57, respectively). Bland-Altman plots indicated reasonably consistent agreement for UPFs and MPFs groups in children and adolescents. Classification by quintiles was acceptable in all groups. CONCLUSIONS: Data from this study indicated reasonable relative validity of the SFFQ to rank the percentage of energy intake from MPFs and UPFs in Mexican children and adolescents.

Fetal macrosomia (FM) is a condition with adverse consequences for both mother and offspring. The occurrence of this condition has increased worldwide. The objectives of this study were: (1) to estimate the incidence of FM at the national and state levels in Mexico in 2020; (2) to estimate the incidence of FM stratified by maternal and newborn characteristics; (3) to identify the states with the highest risk of FM; (4) to georeference the incidence of FM. Open data from the Birth Information Subsystem were used. Relative risks were estimated by adjusted Poisson regression models. The national incidence of FM was 2.75%. The entity with the lowest incidence was Mexico City (1.28%) and the most affected states were Sonora (6.20%), Baja California Sur (5.44%), and Sinaloa (5.36%), located in the north of the country. The incidence of FM at the national level is below that reported in the international literature. The results of this study can be used for the design and implementation of programs, public policies, and interventions.

BACKGROUND: Ultra-processed foods are recognized as indicators of an unhealthy diet in epidemiological studies. In addition to ultra-processed foods, the NOVA food classification system identifies three other groups with less processing. Unprocessed foods that, together with minimally processed foods (MPF), make NOVA group 1, NOVA group 2 is processed culinary ingredients, and NOVA group 3 is processed foods. OBJECTIVE: To assess the relative validity of the semi-quantitative food frequency questionnaire (SFFQ) to estimate the energy intake for each group NOVA classification system by comparing it with two 24 h-dietary-recall (24DRs) Mexican adults. METHODS: We analyzed dietary information from 226 adults included <60 and ≥60 years with complete SFFQ and two 24DRs from the National Health and Nutrition Survey 2012. We reported mean differences, Spearman correlation coefficients, intra-class correlations coefficients, Bland-Altman plots, and weighted kappa between measures. RESULTS: The percentage energy intake from unprocessed and minimally processed foods group, Spearman correlation coefficients was 0.54 in adults <60 years and 0.42 in adults ≥60 years, while ultra-processed foods group was 0.67 and 0.48, respectively. The intra-class correlation coefficients in the unprocessed and minimally processed foods group was 0.51 in adults <60 years and 0.46 in adults ≥60 years, and for the ultra-processed foods group were 0.71 and 0.50, respectively. Bland-Altman plots indicated reasonably consistent agreement for unprocessed and minimally processed foods group and ultra-processed foods group in adults <60 years and adults in the ≥60 age group. Weighted kappa was 0.45 in the ultra-processed foods group to adults <60 years and was 0.36-≥60 years. CONCLUSION: The SFFQ had acceptable validity to rank the percentage of energy intake from unprocessed and minimally processed foods group and ultra-processed foods group in Mexican adults, both in adults under 60 years and who were 60 years old or older.
RESUMO
Introduction: Maternal and child malnutrition is a worldwide public health problem with short, medium, and long-term adverse consequences for both mother and child. In Mexico, maternal and child malnutrition represents a serious public health problem that must be urgently addressed. In this context, Primary Health Care (PHC) plays an important role in the prevention, detection, monitoring, and treatment of the different forms of maternal and child malnutrition. Assessing the quality of nutritional care offered at this level of care is necessary in order to improve it; however, there are no indicators for the evaluation of this quality. Therefore, this study aimed at developing a set of indicators to assess the quality of maternal and child nutritional care at PHC. Methods: We developed indicators for different stages of life: preconception, pregnancy, infancy, and preschool age. A systematic review of the literature on clinical guidelines for the prevention, diagnosis, and treatment of the different forms of malnutrition was carried out; the recommendations of the guidelines evaluated with good quality were extracted. Results: Based on these recommendations, 22 indicators were constructed. A pilot study was carried out to validate the indicators and 16 indicators were selected to assess the maternal and child nutritional care at PHC.
RESUMO
BACKGROUND: A product package can be a powerful marketing tool to persuade and attract consumers at the point-of-sale. Evidence shows that most advertised products have low nutritional quality. Currently, Mexico has incorporated advertising regulations on food and beverage packaging. OBJECTIVES: To analyze the advertising strategies used to target children on packaging and to assess the nutritional quality of sugar-sweetened beverages available in the Mexican market. METHODS: Photographs of 2380 beverages available in retail stores in Mexico City from January to March 2017 were analyzed. Beverages were classified as displaying child-directed strategies or nondirected strategies. Nutrition quality was evaluated using the Pan American Health Organization nutrient profile model. RESULTS: The use of characters was the most frequent strategy among beverages with child-directed strategies (82.0%). The evaluation of nutrition quality found that 88.0% (P < .001) of sugar-sweetened beverages with child-directed strategies were excessive in free sugars and 56.9% (P < .001) contained other sweeteners. Beverages with more than two advertising strategies have the highest proportion of excessive free sugars (93.4%, 95% CI 82.8-98.6). CONCLUSIONS: The use of characters and other visual strategies were frequently used in the packaging of sugar-sweetened beverages with child-directed strategies. In addition, these beverages are excessive in free sugars and contain a large number of products with other sweeteners.

BACKGROUND: People with a previous diagnosis of non-communicable diseases (NCDs) are more likely to develop serious forms of COVID-19 or die. Mexico is the country with the fourth highest fatality rate from SARS-Cov-2, with high mortality in younger adults. OBJECTIVES: To describe and characterize the association of NCDs with the case-fatality rate (CFR) adjusted by age and sex in Mexican adults with a positive diagnosis for SARS-Cov-2. METHODS: We studied Mexican adults aged ≥20 years who tested positive for SARS-Cov-2 during the period from 28 February to 31 July 2020. The CFR was calculated and associations with history of NCDs (number of diseases and combinations), severity indicators and type of institution that treated the patient were explored. The relative risk (RR) of death was estimated using Poisson models and CFR was adjusted using logistic models. RESULTS: We analysed 406 966 SARS-Cov-2-positive adults. The CFR was 11.2% (13.7% in men and 8.4% in women). The CFR was positively associated with age and number of NCDs (p trend <0.001). The number of NCDs increased the risk of death in younger adults when they presented three or more NCDs compared with those who did not have any NCDs [RR, 46.6; 95% confidence interval (CI), 28.2, 76.9 for women; RR, 16.5; 95% CI, 9.9, 27.3 for men]. Lastly, there was great heterogeneity in the CFR by institution, from 4.6% in private institutions to 18.9% in public institutions. CONCLUSION: In younger adults, higher CFRs were associated with the total number of NCDs and some combinations of type 2 diabetes, chronic kidney disease, chronic obstructive pulmonary disease and cardiovascular disease.

In Colombia, like many countries in the world, due to the increase in population of elderly people, mistreatment has increased, which has physical, psychological and social consequences for the individual and major repercussions on society. The detection of abuse is a complex task, among other aspects, due to the concealment of victims and the lack of valid, reliable detection instruments that are in keeping with the sociocultural context. Professionals responsible for dealing with these situations must have an instrument that allows early detection. The objective of this study was to adapt and validate the Family Abuse Screening Questionnaire for Elderly People in Colombia. A cross-sectional study with mixed methods was carried out in two stages from 2017 to 2018. In the first stage, linguistic and semantic adaptation was carried out using translation, synthesis, back translation, expert analysis and pilot testing with 30 abused and non-abused elderly people. In the second stage, the validity and reliability of the questionnaire were obtained by means of an exploratory factor analysis and Cronbach's Alpha, using STATA 13. In the results, we provided a Socially and Culturally Adapted Family Abuse Screening Questionnaire for elderly people in Colombia with a Cronbach's Alpha of 0.82, sensitivity value of 86.9% (p < 0.05) and a specificity value of 84% (p < 0.05), detecting abuse with 4 or more positive responses to abuse. The application of the screening questionnaire by health and social services professionals will prevent further damage to social and physical health in the elderly people in Colombia, as well as reduce the costs of care in institutions.

According to the WHO, low birth weight (LBW) affects 15-20% of newborns worldwide. In Mexico, there are no national, state, nor municipal estimates that inform the country's situation over time. The purpose of this study was to estimate the incidence of LBW at the national, state, and municipal levels from 2008 to 2017, and to estimate the LBW incidence based on maternal sociodemographic characteristics, prenatal care and marginalization indexes at the national level using open national data. We used spatial data analysis to georeferenced LBW incidence at the three levels of geographical disaggregation studied. At the national level, the incidence of LBW increased progressively from 6.2% (2008) to 7.1% (2017), and the country's capital represented the area with the highest incidence. Southeastern and central states reported the highest LBW regional incidence. At the municipal level, the number of municipalities with an incidence of LBW ≥8% increased in both male and female newborns. The incidence of LBW was higher as the marginalization indexes increases. The results from this study may assist in the identification of vulnerable groups and the development of public health programs and policies with an intersectoral approach that improves maternal and child nutrition.

BACKGROUND: The prevalence of overweight and obesity in Mexican schoolchildren has increased in the past three decades. Dietary pattern approaches to assess diet have been used to study the relation between nutrition and chronic conditions. OBJECTIVE: The objective of this study is to analyze the association between dietary patterns (DP) and overweight and obesity in Mexican schoolchildren. METHODS: We analyzed information from schoolchildren who participated in the National Health and Nutrition Survey 2012 (ENSANUT-2012). Dietary information was obtained through a 24-h recall of 2751 children (5-11 year). Foods were classified into 33 groups, and the DPs were identified by cluster analysis (k-means method). Weight and height were measured to estimate the body mass index (BMI), by classifying overweight if the Z score was >1 and ≤2 standard deviations (SD), and obesity when the Z score was >2SD. To analyze the association, a Poisson regression model was used, adjusting by age, region, area of residence, socioeconomic status (SES), and the survey design. RESULTS: Four DPs were identified: "Traditional", "Industrialized", "Varied", and "Modern". The "Modern" DP was associated with obesity (PR = 1.7) (p < 0.05) compared with the "Traditional" DP. CONCLUSIONS: The "Modern" DP could be influencing the development of obesity in Mexican schoolchildren. The promotion of healthy food and public health strategies to those food groups that should be discouraged are necessary to reverse the obesity epidemic in Mexican children.

OBJECTIVES: To describe the prevalence of previously diagnosed diabetes among Mexican adults, to characterize the associated risk factors, and to describe which glycemic control strategies are the most used. METHODS: We analyzed data from 8,631 adults aged ≥20 years who participated in the ENSANUT-2016 and from whom we gathered data about previously diagnosed diabetes, risk factors, glycemic control strategies, and measures to prevent complications. RESULTS: The prevalence of previously diagnosed diabetes in Mexican adults was 9.4% (10.3% in women and 8.4% in men). The adjusted OR for having diabetes was higher in adults aged ≥60 years (OR = 11.0 in women and OR = 30.7 in men) than in adults aged 20-39 years (OR = 1.0). The adjusted OR for having diabetes was higher in overweight men (OR = 1.7) than in men with normal BMI (OR = 1.0). A total of 30.5% of adults with diabetes did not report any control strategies, 44.9% measured their venous blood glucose, and 15.2% used the HbA1C as an indicator of glycemic control. Only 46.4% of them reported preventive measures. DISCUSSION: Diabetes is a common disease among Mexican adults. Being older or overweight are risk factors for an adult to be diagnosed with diabetes. Most adults with diabetes evaluate their glycemic control but only half practice preventive measures.

BACKGROUND: Non-communicable diseases, such as obesity, diabetes, and hypertension, can be prevented and treated through a balanced nutrient-rich diet. Nutrition labels have been recognized as crucial to preventing obesity and non-communicable diseases through a healthier diet. OBJECTIVE: Our aim was to examine the association between nutrition label use and chronic conditions (overweight, obesity, previously diagnosed diabetes, and hypertension) among an adult Mexican population. DESIGN: This was a cross-sectional study that used data from the Mexican National Health and Nutrition Survey of 2016 (ENSANUT MC 2016). PARTICIPANTS/SETTING: The participants were 5,013 adults aged 20 to 70 years old. Older adults (>70 years), illiterate participants, pregnant women, and participants with implausible blood pressure data were excluded from the sample. The survey was conducted from May to August 2016 in the participants' households. MAIN OUTCOME MEASURES: We measured chronic conditions (overweight, obesity, previously diagnosed diabetes, and hypertension). STATISTICAL ANALYSES PERFORMED: Pearson χ2 test was used to examine the associations among the use of nutrition labels and sociodemographic characteristics and chronic conditions. Multiple logistic regression was used to determine the association between nutrition label use and chronic conditions adjusting for the effect of confounding variables like sex, age, body mass index, education level, marital status, ethnicity, residence area, region, and socioeconomic status. RESULTS: From the total sample, 40.9% (95% CI 38.4% to 43.8%) reported using nutrition labeling. Respondents with overweight or obesity were less likely to use nutrition labels (odds ratio 0.74; P<0.05). Participants who self-reported diabetes had significantly lower odds of nutrition label use than participants who did not report to have diabetes (odds ratio 0.66; P<0.05). Participants having 3 chronic conditions had lower odds of nutrition label use (odds ratio 0.34; P<0.01) relative to having zero chronic conditions. CONCLUSIONS: This study suggests an association between nutrition label use and chronic conditions (obesity and diabetes). These findings demonstrate that people with obesity, diabetes, and a combination of chronic conditions were less likely to use nutrition labels than people without these conditions.
