RESUMEN
BACKGROUND: Poor-quality diets are a major risk factor for noncommunicable diseases. Few studies in Mexico have tested whether higher expenditures are needed to purchase high-quality food. OBJECTIVE: The objective of the study was to assess how dietary quality of food purchases was associated with household food at home expenditures. DESIGN: This study was a secondary analysis of cross-sectional data from the National Household Income and Expenditure Survey (EncuestaNacional de Ingresos y Gastos de los Hogares [ENIGH] 2018). PARTICIPANTS/SETTING: The study included 74 469 households with information on food and beverage purchases in Mexico in 2018. MAIN OUTCOME MEASURES: Quarterly household food at home expenditures by adult equivalent (AE) for all food groups that were scored with the Global Dietary Quality Score (GDQS) for food purchases expressed in dollars/quarterly/AE. STATISTICAL ANALYSES PERFORMED: Adjusted generalized linear models were used to evaluate the association between GDQS for food purchases (expressed in tertiles: low, mid, and high) and quarterly food expenditures. The analyses were performed at the national level by place of residence and income quintile. RESULTS: At the national level, the difference in food expenditures between the high- and the low-GDQS groups was +$13.85/AE. By place of residence, the difference between the high- and the low-GDQS groups was +$17.31/AE in urban and +$5.12/AE in rural areas. For income quintile 1 (lowest), there was a statistical difference of -$4.79/AE and +$43.25 for quintile 5 (highest). CONCLUSIONS: Quality of food purchases can be associated with higher or lower expenditures depending on the specific food purchased. High GDQS is associated with lower expenditures among the lowest-income households as they purchase less expensive options compared with high-income households.
RESUMEN
BACKGROUND/OBJECTIVES: Obesity prevalence in Mexican children has increased rapidly and is among the highest in the world. We aimed to estimate the longitudinal association between nonessential energy-dense food (NEDF) consumption and body mass index (BMI) in school-aged children 5 to 11 years, using a cohort study with 6 years of follow-up. SUBJECTS/METHODS: We studied the offspring of women in the Prenatal omega-3 fatty acid supplementation, child growth, and development (POSGRAD) cohort study. NEDF was classified into four main groups: chips and popcorn, sweet bakery products, non-cereal based sweets, and ready-to-eat cereals. We fitted fixed effects models to assess the association between change in NEDF consumption and changes in BMI. RESULTS: Between 5 and 11 years, children increased their consumption of NEDF by 225 kJ/day (53.9 kcal/day). In fully adjusted models, we found that change in total NEDF was not associated with change in children's BMI (0.033 kg/m2, [p = 0.246]). However, BMI increased 0.078 kg/m2 for every 418.6 kJ/day (100 kcal/day) of sweet bakery products (p = 0.035) in fully adjusted models. For chips and popcorn, BMI increased 0.208 kg/m2 (p = 0.035), yet, the association was attenuated after adjustment (p = 0.303). CONCLUSIONS: Changes in total NEDF consumption were not associated with changes in BMI in children. However, increases in the consumption of sweet bakery products were associated with BMI gain. NEDF are widely recognized as providing poor nutrition yet, their impact in Mexican children BMI seems to be heterogeneous.

Diet diversity becomes especially relevant during adolescence to satisfy the adequate micronutrient intake. Diet diversity (DD) and micronutrient probability of adequacy (PA) were studied in 818 Costa Rican (CR) and 1202 Mexican (MX) adolescents aged 13-18 years. DD was compared using the Minimum Dietary Diversity (MDD) score. Receiver-operating characteristic (ROC) curves were employed to identify the optimal MDD for each sample from the respective countries. The mean MDD for the overall CR sample was 4.17 ± 1.43 points, and for the MX sample, the mean MDD was 4.68 ± 1.48 points. The proportion of adolescents with a DD was significantly higher in Costa Rica than in Mexico (66.5% vs. 55.6%; p < 0.0001). Also, DD was higher in rural Costa Rican adolescents, while no difference was found in the MX adolescents by area of residence. CR adolescents reported significantly higher PA than MX participants for 6 of the 11 micronutrients assessed. The calcium PA in MX adolescents was significantly higher than in the CR sample (MX: 0.84 vs. CR: 0.03; p < 0.0001), while low PA was obtained for iron in both countries (CR: 0.01 vs. MX: 0.07; p < 0.0001). In Costa Rica and Mexico, nutritional interventions and assessing the compliance of food-fortifying programs are needed to improve the PA of diverse micronutrients.
RESUMEN
BACKGROUND: The Global Diet Quality Score (GDQS) was developed for monitoring nutrient adequacy and diet-related noncommunicable disease risk in diverse populations. A software application (GDQS app) was recently developed for the standardized collection of GDQS data. The application involves a simplified 24-h dietary recall (24HR) where foods are matched to GDQS-food groups using an onboard database, portion sizes are estimated at the food group level using cubic models, and the GDQS is computed. OBJECTIVES: The study aimed to estimate associations between GDQS scores collected using the GDQS app and nutrient adequacy and metabolic risks. METHODS: In this cross-sectional study of 600 Thai males and nonpregnant/nonlactating females (40-60 y), we collected 2 d of GDQS app and paper-based 24HR, food-frequency questionnaires (FFQs), anthropometry, body composition, blood pressure, and biomarkers. Associations between application scores and outcomes were estimated using multiple regression, and application performance was compared with that of metrics scored using 24HR and FFQ data: GDQS, Minimum Dietary Diversity-Women, Alternative Healthy Eating Index-2010, and Global Dietary Recommendations score. RESULTS: In covariate-adjusted models, application scores were significantly (P < 0.05) associated with higher energy-adjusted mean micronutrient adequacy computed using 24HR (range in estimated mean adequacy between score quintiles 1 and 5: 36.3%-44.5%) and FFQ (Q1-Q5: 40.6%-44.2%), and probability of protein adequacy from 24HR (Q1-Q5: 63%-72.5%). Application scores were inversely associated with BMI kg/m2 (Q1-Q5: 26.3-24.9), body fat percentage (Q1-Q5: 31.7%-29.1%), diastolic blood pressure (Q1-Q5: 84-81 mm Hg), and a locally-developed sodium intake score (Q1-Q5: 27.5-24.0 points out of 100); positively associated with high-density lipoprotein cholesterol (Q1-Q5: 49-53 mg/dL) and 24-h urinary potassium (Q1-Q5: 1385-1646 mg); and inversely associated with high midupper arm circumference (Q5/Q1 odds ratio: 0.52) and abdominal obesity (Q5/Q1 odds ratio: 0.51). Significant associations for the application outnumbered those for metrics computed using 24HR or FFQ. CONCLUSIONS: The GDQS app effectively assesses nutrient adequacy and metabolic risk in population surveys.

PURPOSE OF REVIEW: Taxes on sugary drinks and foods have emerged as a key strategy to counteract the alarming levels of diabetes worldwide. Added sugar consumption from industrialized foods and beverages has been strongly linked to type 2 diabetes. This review provides a synthesis of evidence on how taxes on sugary products can influence the onset of type 2 diabetes, describing the importance of the different mechanisms through which the consumption of these products is reduced, leading to changes in weight and potentially a decrease in the incidence of type 2 diabetes. RECENT FINDINGS: Observational studies have shown significant reductions in purchases, energy intake, and body weight after the implementation of taxes on sugary drinks or foods. Simulation studies based on the association between energy intake and type 2 diabetes estimated the potential long-term health and economic effects, particularly in low- and middle-income countries, suggesting that the implementation of sugary food and beverage taxes may have a meaningful impact on reducing type 2 diabetes and complications. Public health response to diabetes requires multi-faceted approaches from health and non-health actors to drive healthier societies. Population-wide strategies, such as added sugar taxes, highlight the potential benefits of financial incentives to address behaviors and protective factors to significantly change an individual's health trajectory and reduce the onset of type 2 diabetes worldwide, both in terms of economy and public health.

Evidence about the association between breastfeeding and its duration with growth, appetite and satiety indicators, and adiposity in low and middle-income countries facing nutritional transition is scarce. The aim of this study was to evaluate the association between longitudinal patterns of breastfeeding (exclusive [EBF] and continued [CBF]) with adiposity and growth, and the mediating role of appetite and satiety indicators in these associations in Mexican children during the first 2 years of life. Information from 378 mother-child pairs from the MAS-Lactancia birth cohort was analysed. Information was collected at birth and at months 1, 3, 6, 9, 12, 18 and 24 of life. Duration of EBF and CBF was computed. Linear mixed models were used to assess the association of EBF and CBF with growth and adiposity. Path analysis was used for mediation analysis. Compared with the reference group (EBF duration <1 month), males with >3 to ≤6 months of EBF had less abdominal circumference (ß = -0.66, p = 0.05), Z-score weight-for-length (ß = -0.17, p = 0.19) and length-for-age (ß = -0.49, p < 0.01). Participants without CBF beyond 6 months had higher BMI Z-score (ß = 0.19, p < 0.01), abdominal circumference (ß = 0.62, p < 0.01) and skinfold sum (ß = 0.80, p = 0.09), and o difference in length-for-age. For EBF, mediation was confirmed for satiety responsiveness on the association with BMI Z-Score, for food fussiness for the association with abdominal circumference and length-for-age Z-score, and enjoyment of food on the association with length-for-age Z-score. For CBF, mediation was confirmed for food fussiness in the association with length-for-age. This study suggests that a longer exposure to EBF and CBF is associated with lower adiposity in children under 2 years of age, and that this association could be partially mediated by appetite and satiety indicators.
RESUMEN
Importance: Tax evaluations have shown effectiveness in reducing purchases of taxed items. However, few studies have looked at changes in overall dietary intake according to national surveys. Objective: To estimate the contribution of taxed and untaxed beverages and foods to dietary intake over time, and the nutritional dietary profile in total beverages and foods consumed. Design, Setting, and Participants: This cross-sectional study used data from 3 National Health and Nutrition Surveys of a nationally representative sample of participants aged older than 1 year in Mexico from 2012 (pretax), 2016, and 2018 (posttax). Data were analyzed from September 2021 to December 2022. Exposure: Taxes on sugar-sweetened beverages and nonessential energy-dense foods implemented since 2014. Main Outcomes and Measures: The outcomes were the contribution of taxed and untaxed beverages to total beverage volume, the contribution of taxed and untaxed foods to total food energy, and the energy density and content of added sugars and saturated fats. Outcomes were assessed with 24-hour recalls (24HR) (2012 and 2016) and Food Frequency Questionnaires (FFQ) (2012, 2016, and 2018), and were adjusted by sociodemographic and macroeconomic variables. Results: A total of 17â¯239 participants were analyzed from 2012, 18â¯974 from 2016, and 30â¯027 from 2018; approximately 50% were men, and approximately 75% lived in urban areas. According to 24HRs, the contribution of taxed beverages to total beverage volume changed -2.3 (95% CI, -4.4 to -0.2) percentage points from 2012 to 2016, while water increased. The contribution of taxed foods to total food energy changed -3.0 (95% CI, -4.2 to -1.8) percentage points, while untaxed whole grains, processed meats, other animal sources, and sugars and desserts increased. The content in total beverages of added sugars changed -1.1 kcal/100 mL (95% CI, -2.0 to -0.2), and in total foods, the content of added sugar changed -0.6 %kcal (95% CI, -1.0 to -0.2), saturated fat changed -0.8 %kcal (95% CI, -1.1 to -0.4), and energy density changed -9.8 kcal/100 g (95% CI, -13.8 to -5.8). Main results were consistent with the FFQ (up to 2018), with some differences in subgroups and nutritional components. Conclusions and Relevance: The findings of this study on 3 cross-sectional national dietary surveys are consistent with previous evaluations; after tax implementation, there was a decrease in the contribution of taxed items. Furthermore, some unhealthy untaxed items increased, but the content of unhealthful nutritional components, particularly added sugar, in overall beverages and foods decreased.

RESUMEN
BACKGROUND: Processed discretionary foods and drinks (industrialised sugary drinks, sweet and savoury snacks, and grain-based sweets) are often target of policies aimed at regulating the food environment. We aimed to understand if a lower intake of processed foods or drinks is associated with substitution or complementation patterns and overall intake. METHODS: We analysed a subsample with two 24-h dietary recalls of the Mexican National Health and Nutrition Survey 2012 (358 children, 253 adolescents and 278 adults). We compared within-person, energy and added sugar intakes between days with and without consumption of each food group with fixed-effects regressions. We estimated the relative change (change in intake when not consumed/average intake when consumed × 100). RESULTS: Processed discretionary foods were not fully substituted, as total energy was 200-400 kcal/day lower when these foods were not consumed. The change in total intake was larger than the intake when consumed (i.e., complemented) for industrialised sugary drinks in adolescents (-136%) and adults (-215%), and sweet, savoury snacks for children (-141%). The change was lower (i.e., partially substituted) for grain-based sweets among children (-78%) and adolescents (-73%). For added sugars, most processed discretionary groups were complemented. CONCLUSIONS: Days without intake of processed discretionary foods were associated with lower total energy and lower added sugar intake compared to days when those foods were consumed. This suggests that regulatory policies to reduce the intake of processed foods could have a meaningful impact on improving the overall diet.

To improve the health of our planet and develop sustainable food policies, it is important to understand the health impact of a diet pattern that considers planetary and population health. We used data from the Mexican Teachers' Cohort (MTC) to estimate the association between the EAT-Lancet healthy reference diet (EAT-HRD) and type 2 diabetes (T2D) incidence. We included 74,671 women aged ≥25 years, free of T2D at baseline. A validated food frequency questionnaire (FFQ) was used to assess dietary intake. We created an EAT-HRD score based on 15 food groups recommended by the EAT-Lancet Commission (range from 0 to 15). T2D cases were identified through self-report and cross-linkage with clinical and administrative databases. We used Cox proportional hazards models to estimate the association between categories of the EAT-HRD score with T2D incidence. During a median follow-up of 2.16 y (IQR 1.8-4.3 y), we identified 3241 T2D incident cases. The median EAT-HRD score was 6 (IQR 5-7). In multivariable analyses, when comparing extreme categories, higher adherence to the EAT-HRD score was associated with lower T2D incidence (HR 0.90; 95% CI 0.75, 1.10), yet, the estimation was imprecise. Compared to those who did not meet the EAT-HRD recommendations, adhering to the red meat, legumes, and fish recommendations was associated with lower T2D incidence. Meeting the recommendation of dairy and added sugars was associated with an increased incidence of T2D. Higher adherence to a diet designed to promote environmental and human health may help prevent T2D incidence among women in a middle-income country.

BACKGROUND: Currently, 30% of the total energy intake in the Mexican diet comes from ultra-processed foods. Although its consumption is associated with high intakes of added sugar and saturated fats and low intakes of dietary fibre, there is no evidence regarding its association with dietary diversity and micronutrient intake. The present study evaluated the association between ultra-processed foods consumption with dietary diversity and micronutrient intake in Mexico. METHODS: Ultra-processed foods items were identified in a 24-h recall from a sample of 10,087 participants aged ≥ 1 year. The minimum dietary diversity (MDD) was established by using the Food and Agriculture Organization 10 food group indicators with unprocessed, minimally processed and processed foods. The study conducted multiple linear regression models to evaluate the association between quintiles of energy contribution of ultra-processed foods with dietary diversity and micronutrient intake. RESULTS: A high consumption of ultra-processed foods was associated with a low dietary diversity and micronutrients intake. The association between ultra-processed foods and MDD was not linear (47.1%, 57.1%, 52.5%, 45.0% and 28.0% of participants achieved the MDD). On the other hand, the association was linear and negatively associated with: niacin, pantothenic acid, pyridoxine, folate, vitamin B12 , vitamin C, vitamin E, zinc, calcium, magnesium, potassium and phosphorus (p < 0.05). CONCLUSIONS: These findings are relevant in the context of the double burden of malnutrition currently faced in Mexico. Increasing dietary diversity and micronutrient intake is essential by discouraging ultra-processed foods consumption. However, other strategies are also needed to promote the dietary diversity and increase the consumption of unprocessed and minimally processed foods.

OBJECTIVE: To estimate energy contribution (EC) of food groups in 2016, to compare consumption against Mexican Dietary Guidelines, and to examine changes in EC from 2012 to 2016. MATERIALS AND METHODS: We analyzed 24-hour dietary recalls from the 2012 and 2016 National Health and Nutrition Surveys (Ensanut). Foods and beverages were clas-sified into eight food groups: cereals, legumes, dairy, meats, fruit and vegetables, fats and oils, sugar-sweetened beverages, and high in saturated fat and added sugar (HSFAS) products. RESULTS: Cereals had the highest EC (30.1%), followed by meats (15.9%), HSFAS products (15.5%), and SSBs (10.5%). Fruits and vegetables, and legumes had the lowest contribu-tion with 6.4 and 3.8%, respectively. SSBs, meats, and HSFAS products were 250, 59 and 55% above the recommended intake, respectively. CONCLUSIONS: This analysis confirms the need to generate a food environment conducive to a healthier diet.

BACKGROUND: Access to high-quality dietary intake data is central to many nutrition, epidemiology, economic, environmental, and policy applications. When data on individual nutrient intakes are available, they have not been consistently disaggregated by sex and age groups, and their parameters and full distributions are often not publicly available. OBJECTIVES: We sought to derive usual intake distributions for as many nutrients and population subgroups as possible, use these distributions to estimate nutrient intake inadequacy, compare these distributions and evaluate the implications of their shapes on the estimation of inadequacy, and make these distributions publicly available. METHODS: We compiled dietary data sets from 31 geographically diverse countries, modeled usual intake distributions for 32 micronutrients and 21 macronutrients, and disaggregated these distributions by sex and age groups. We compared the variability and skewness of the distributions and evaluated their similarity across countries, sex, and age groups. We estimated intake inadequacy for 16 nutrients based on a harmonized set of nutrient requirements and bioavailability estimates. Last, we created an R package-nutriR-to make these distributions freely available for users to apply in their own analyses. RESULTS: Usual intake distributions were rarely symmetric and differed widely in variability and skewness across nutrients and countries. Vitamin intake distributions were more variable and skewed and exhibited less similarity among countries than other nutrients. Inadequate intakes were high and geographically concentrated, as well as generally higher for females than males. We found that the shape of usual intake distributions strongly affects estimates of the prevalence of inadequate intakes. CONCLUSIONS: The shape of nutrient intake distributions differs based on nutrient and subgroup and strongly influences estimates of nutrient intake inadequacy. This research represents an important contribution to the availability and application of dietary intake data for diverse subpopulations around the world.

Abstract: In recent decades, the growing obesity epidemic in Mexico has become one of the most important public health challenges faced by the country. With support from the World Obesity Federation, we formed a working group in 2021 to identify and summarize priority actions that Mexico can take to face this epidemic. More than 1 000 health professionals joined the development and discussion process. Recommendations from previously published, high-level documents and guidelines were taken into account. In commemoration of World Obesity Day 2022, this statement is presented as input for health care professionals to develop actions to address obesity. The statement includes 10 recommendations that include population-level and individual-level actions. It emphasizes the importance of social participation, comprehensive interventions with a person- centered perspective, planetary sustainability, on improving education and communication campaigns, as well as fostering a built environment that promotes active living, and shielding prevention and control efforts from conflicts of interest. The statement calls for obesity to be treated seriously, based on scientific evidence, in a timely and comprehensive manner, employing a life-course and ethical approach that does not perpetuate weight stigma in society.
RESUMEN
This study assessed associations between ultraprocessed food consumption and dietary nutrient profile linked to obesity in children and adolescents in Argentina, Australia, Brazil, Chile, Colombia, Mexico, the United Kingdom, and the United States using nationally representative data collected between 2004 and 2014. Linear regression models were used to evaluate associations between dietary share of ultraprocessed foods (country and age group-specific quintiles and a 10% share increase) and the energy density of diets and their content of free sugars and fiber. Ultraprocessed foods, defined by the NOVA system, ranged from 18% of total energy intake among preschool children in Colombia to 68% among adolescents in the United Kingdom. In almost all countries and age groups, increases in the dietary share of ultraprocessed foods were associated with increases in energy density and free sugars and decreases in fiber, suggesting that ultraprocessed food consumption is a potential determinant of obesity in children and adolescents. Effective global policy action to address growing ultraprocessed food consumption and childhood obesity is urgently needed.

OBJECTIVE: To establish the cutoff point for a Minimum Dietary Diversity (MDD) that most accurately predicts the Mean Probability Adequacy (MPA) of 11 micronutrients in the Mexican population, and estimate the population prevalence above it. SUBJECTS AND METHODS: We analyzed a 24 h-recall collected in a sample of 10,087 participants (≥1-year-old) from the 2012 Mexican National Health and Nutrition Survey. Foods were classified into ten food group indicators (FGIs) of the Food Agriculture Organization (FAO). The cutoff points of MDD were established as follows: (1) sum of the number of FGIs in the participant's diet; (2) micronutrient intake adequacy estimated by the probability approach method of the FAO; (3) Receiver operating characteristic curves generated by age groups to assess the performance of the number FGIs consumed in predicting the MPA. RESULTS: The cutoff points of MMD established by age groups were: ≥4 FGIs in preschool-aged children (75.94% of sensitivity and 72.55% of specificity); ≥5 FGIs in school-aged children (60.51% of sensitivity and 72.82% of specificity) and adolescents (70.01% of sensitivity and 59.38% of specificity); and six in adults (62.26% of sensitivity and 70.33% of specificity) and elders (66.67% of sensitivity and 73.33% of specificity). Based on these cutoff points, we observed that 75% of the preschool-aged children, ~60% of school-aged children and adolescents, and less than 40% of adults and elders were above the MDD. CONCLUSION: This study provides novel insight into the specific MDD cutoff point to predict micronutrient adequacy in the Mexican population.
