Association Between the Nutritional Quality of Food Purchases and Household Food at Home Expenditures in Mexico.

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.

Comparison of Dietary Intake Before vs After Taxes on Sugar-Sweetened Beverages and Nonessential Energy-Dense Foods in Mexico, 2012 to 2018.

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.

Estimating national and subnational nutrient intake distributions of global diets.

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.

Factors Associated With Dietary Quality During Initial and Later Stages of the COVID-19 Pandemic in Mexico.

The COVID-19 pandemic disrupted the global economy and modified lifestyles. The aim of our study was to identify factors associated with dietary quality, and their frequency, in Mexican adults at the initial and later stages of the pandemic. Two online surveys were conducted between June and July 2020 ( = 3,131) and between November and December 2020 ( = 1,703 including non-participants from 1st round).

Development and Validation of a Novel Food-Based Global Diet Quality Score (GDQS).

Background: Poor diet quality is a major driver of both classical malnutrition and noncommunicable disease (NCD) and was responsible for 22% of adult deaths in 2017. Most countries face dual burdens of undernutrition and NCDs, yet no simple global standard metric exists for monitoring diet quality in populations and population subgroups.

Objectives: We aimed to develop an easy-to-use metric for nutrient adequacy and diet related NCD risk in diverse settings.

Performance of the Global Diet Quality Score with Nutrition and Health Outcomes in Mexico with 24-h Recall and FFQ Data.

Background: The Global Diet Quality Score (GDQS) is intended as a simple global diet quality metric feasible in low- and middle-income countries facing the double burden of malnutrition.

Objective: The aim of this study was to evaluate the performance of the GDQS with markers of nutrient adequacy and chronic disease in nonpregnant nonlactating (NPNL) Mexican women of reproductive age and to compare it with the Alternate Healthy Eating Index-2010 (AHEI-2010) and the Minimum Dietary Diversity for Women (MDD-W).

Methods: We included NPNL women aged 15 to 49 y from the Mexican National Health and Nutrition Surveys (2012 and 2016) with 24-h recall (n = 2542) or a FFQ (n = 4975) (separate samples).

Changes in the Global Diet Quality Score, Weight, and Waist Circumference in Mexican Women.

Background: Evidence on concurrent changes in overall diet quality and weight and waist circumference in women of reproductive age from low- and middle-income countries is limited.

Objectives: We examined the associations of changes in the Global Diet Quality Score (GDQS) and each GDQS food group with concurrent weight and waist circumference change in Mexican women.

Methods: We followed prospectively 8967 nonpregnant nonlactating women aged 25-49 y in the Mexican Teachers' Cohort between 2006 and 2008.

There's an App for That: Development of an Application to Operationalize the Global Diet Quality Score.

Background: The global diet quality score (GDQS) is a simple, standardized metric appropriate for population-based measurement of diet quality globally.

Objectives: We aimed to operationalize data collection by modifying the quantity of consumption cutoffs originally developed for the GDQS food groups and to statistically evaluate the performance of the operationalized GDQS relative to the original GDQS against nutrient adequacy and noncommunicable disease (NCD)-related outcomes.

Methods: The GDQS application uses a 24-h open-recall to collect a full list of all foods consumed during the previous day or night, and automatically classifies them into corresponding GDQS food group.

Toward a healthy and sustainable diet in Mexico: where are we and how can we move forward?

Background: Dietary recommendations worldwide have focused on promoting healthy diets to prevent diseases. In 2019, the EAT-Lancet Commission presented global scientific targets for healthy diets and sustainable food production and proposed a healthy reference diet (EAT-HRD) that can be adapted to the culture, geography, and demography of the population and individuals in any country.

Objectives: We aimed to describe the daily energy intake from food groups and subgroups in Mexican adults relative to the EAT-HRD and propose an adaptation of the EAT-HRD to the Mexican context.

Prevalence of inadequate intake of vitamins and minerals in the Mexican population correcting by nutrient retention factors, Ensanut 2016.

Objective: To estimate the usual intake and the prevalence of inadequacy of selected nutrients in the Mexican population and the potential effect that the nutrient retention factors (NRF) could have on these estimates. Likewise, document the methodology used in the analysis of the 24 hours of the mid-way National Health and Nutrition Survey 2016 (Ensanut MC 2016).

Materials And Methods: Dietary information from the Ensanut MC 2016 was analyzed with and without the use of NRFs.

Self-perception of dietary quality and adherence to food groups dietary recommendations among Mexican adults.

Background: Mexicans' adherence to food group's dietary recommendations is low and an inaccurate self-perception of dietary quality might perpetuate this low adherence. Our aim was to compare the intake and the adherence to the dietary recommendations for several food groups, subgroups, and to an overall Mexican Diet Quality Index (MxDQI), among those that perceived their diet as healthy vs. those that did not.

Higher dietary magnesium intake is associated with lower body mass index, waist circumference and serum glucose in Mexican adults.

Background: Obesity and diabetes mellitus (DM) are public health concerns in Mexico of top-level priority due to their high prevalence and their growth rate in recent decades. The accumulation of adipose tissue leads to an unbalanced release of pro-oxidant factors, which causes cellular damage and favors the development of comorbidities. Recent evidence suggests that oxidative stress also promotes the accumulation of adipose tissue and the development of insulin resistance.
