Little is understood about the patterns and trends in adolescent and adult beverage intake in Mexico or most other countries. Here, we used nationally representative dietary intake, income, and food expenditure surveys, which included 416 adolescents (aged 12-18 y) and 2180 adults (aged >or=19 y) from the 1999 Mexican Nutrition Survey and 7464 adolescents and 21,113 adults from the 2006 Mexican Health and Nutrition Survey. We measured the volume and energy per day contributed by all beverages consumed by the sample subjects. In 2006, Mexican adolescents and adults obtained 20.1 and 22.3%, respectively, of their energy intake from energy-containing beverages. Whole milk, carbonated and noncarbonated sugar-sweetened beverages, fruit juice with various sugar and water combinations added, and alcohol represented the 4 major categories of beverage intake. The trends from the dietary intake surveys showed very large increases in the intake of energy-containing beverages among adolescents and adults between 1999 and 2006. Income elasticities showed a high likelihood that intakes will increase as Mexican incomes continue to rise. Whereas the own-price elasticities for whole milk and sodas were both modest, intakes of these were increasing and higher than those for all other food groups. Energy intake trends and current levels of beverage intakes in Mexico are the highest recorded in a nationally representative survey and present major challenges for public health authorities.

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.

Objective. To describe energy and nutrient intake in adults. Material and Methods. The 2006 Mexican National Health and Nutrition Survey is a nationally representative cross-sectional household survey. A food frequency questionnaire was administered (n= 16 494 adults). Mean percent of adequacy (PA) and inadequacy (PA < 50%) of total energy and macroand micro-nutrient intake was calculated for all subjects and by sociodemographic characteristics. Results. Significant differences in PA and inadequate macro-and micro-nutrient intakes were found among sex, region, rural/urban area, and socioeconomic status tertile. PA < 50% was higher than 20% for vitamin A (26.2%), fat (24.8%), fiber (23.6%), folic acid (23.5%), vitamin C (21.3%) and calcium (21%). Obese subjects reported a lower energy intake than normal weight subjects. Conclusions. A significant proportion of the population was at risk of excessive carbohydrate and fat intake. Across the country there are significant sociodemographic differences in macro-and micro-nutrient intake and a myriad of micronutrient inadequacies continue to persist in Mexico.

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 &lt;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.

BackgroundPlain water (PW) should be the main beverage consumed by the population. However, consumption of caloric beverages (CB) has increased considerably worldwide. The purpose of this paper is to analyze the association between CB and PW intake in Mexican adults with a low socioeconomic status (SES).MethodsIn a cross-sectional design, beverage consumption was evaluated with a 24-h beverages recall using the five-step multiple-pass method recommended by the U.S. Department of Agriculture. Physical activity, anthropometric and sociodemographic information were obtained. CB was defined as those beverages that provide energy, with the exception of low-fat milk and beverages with noncaloric sweeteners. Participants were classified into five groups according to their PW consumption (nondrinkers and four quartiles). Differences between groups were evaluated with ANOVA and Bonferroni tests for multiple comparisons among quartiles. A two-stage Heckman regression model was designed with robust standard errors, adjusting for potential confounders.ResultsA total of 1108 adults between 21 and 59 years of age were evaluated. A negative association was noted between PW intake and CB consumption (p <0.001) with the exception of natural juice, which was positive (p <0.01) and sodas that no differences were found between quartiles. Specifically, for every milliliter of PW, the intake of CB was 3.4, 1.3, 0.68 and 0.38 mL in each quartile, respectively (p <0.001). In Heckman’s model, PW consumers were 0.5 times less likely to consume CB (p = 0.029). This probability increased to 0.9 for low-fat milk, skim milk and beverages without added sugar (LFM-BWAS) consumers (p <0.001). Also, for every 100 mL of PW consumption, CB intake diminished by 20 mL (p <0.001). In turn, for every 100 mL of LFM-BWAS consumption, a reduction of 47 mL in CB was observed (p <0.001).ConclusionsHigher PW consumption was associated with lower CB consumption. This association suggests that future studies are warranted to determine if increasing PW intake in a low SES Mexican population can reduce intake of CB.Electronic supplementary materialThe online version of this article (doi:10.1186/s12889-015-1699-0) contains supplementary material, which is available to authorized users.

Objetivo. Describir los conocimientos cotidianos acerca del consumo de agua simple en adultos “pequeños bebedores” y “grandes bebedores” de agua simple.  Material y métodos. Estudio cualitativo realizado entre abril y agosto de 2010 en México. Se conformaron ocho grupos focales con informantes clave adultos de nivel socioeconómico bajo; la mitad de los grupos se conformaron con hombres y la mitad con mujeres. El análisis de datos fue realizado mediante: a) codificación y categorización de acuerdo con literatura revisada acerca de hidratación, y b) mapeo conceptual, reconociendo proposiciones y afirmaciones hechas por los participantes. Resultados. Pequeños y grandes bebedores tienen conocimientos cotidianos similares sobre el agua simple; utilizan los mismos ejes epistemológicos para explicar la ingesta de agua simple en función de lo que “el cuerpo necesite”. Ambos grupos tienen la noción de que el agua simple y el refresco “pueden ser dañinos” si se beben en exceso. Conclusiones. El conocimiento cotidiano sobre el agua se relaciona con el refresco, bebida que sirve para comparación y como sustituto. Los conceptos sobre el agua y el refresco se construyen con base en la experiencia personal y en las nociones sobre el efecto de ambos en el cuerpo y en la mente. Estas representaciones se utilizan para valorar la ingesta de líquidos y pueden constituirse como barreras para el consumo de agua simple.
