- ItemA Landscape of Micronutrient Dietary Intake by 15-to 65-Years-Old Urban Population in 8 Latin American Countries: Results From the Latin American Study of Health and Nutrition(2024) Monge-Rojas, Rafael; Vargas-Quesada, Rulaman; Previdelli, Agatha Nogueira; Kovalskys, Irina; Herrera-Cuenca, Marianella; Cortes, Lilia Yadira; Garcia, Martha Cecilia Yepez; Liria-Dominguez, Reyna; Rigotti, Attilio; Fisberg, Regina Mara; Ferrari, Gerson; Fisberg, Mauro; Gomez, GeorginaBackground: Latin American countries have shifted from traditional diets rich in micronutrients to a Westernized diet rich in high energy-dense foods and low in micronutrients.
- ItemAdherence to the EAT-Lancet Diet is Not Associated With Weight Status in a Latin American Urban Multicentric Study(Wiley, 2025) Vargas-Quesada, Rulaman; Monge-Rojas, Rafael; Romero-Zuniga, Juan Jose; Araya-Bastias, Carolina; Kovalskys, Irina; Herrera-Cuenca, Marianella; Cortes, Lilia Yadira; Garcia, Martha Cecilia Yepez; Liria-Dominguez, Reyna; Rigotti Rivera, Attilio; Fisberg, Mauro; Gomez, GeorginaThe overweight/obesity high prevalence and the effects of climate change in Latin America underscores the possible positive outcomes of adopting a healthy and sustainable diet to respond to the region's burden of nutrition-related noncommunicable diseases (NCDs). However, research on adherence to the EAT-Lancet diet in Latin America and its association with overweight/obesity is limited. This study explores the relationship between the EAT-Lancet diet adherence and overweight/obesity in a cross-sectional and urban multicentric study involving 6683 participants aged 15-65. Adherence to the EAT-Lancet diet was evaluated using the Planetary Health Diet Index (PHDI). The findings indicate that high adherence to the EAT-Lancet diet (fifth quintile) was not significantly associated with overweight/obesity (reference: first PHDI quintile, PR: 1.057, CI: 0.993-1.125, p-trend = 0.140) after adjusting for key covariates. Equivalent outcomes were found when assessing adherence to the EAT-Lancet diet using the EAT-Lancet Index, the World Index for Sustainability and Health (WISH), and the Healthy and Sustainable Diet Index (HSDI), after adjusting for the same variables. The persistently high prevalence of overweight/obesity among different adherence levels to the dietary pattern and the study's design, do not appear to be the key factors contributing to the lack of association between these variables. Instead, the considerably low adherence to the EAT-Lancet diet in the sample as well as the low variability in adherence across participants with and without excess weight might help explain the lack of observed association. However, further research is needed to verify this conclusion.
- ItemExploring the FAO Minimum Dietary Diversity Indicator as a Suitable Proxy of Micronutrient Adequacy in Men and Women Across Reproductive and Non-reproductive Ages in 8 Latin American Countries(2024) Gomez, Georgina; Monge-Rojas, Rafael; Vargas-Quesada, Rulaman; Previdelli, Agatha Nogueira; Quesada, Dayana; Kovalskys, Irina; Herrera-Cuenca, Marianella; Cortes, Lilia Yadira; Garcia, Martha Cecilia Yepez; Liria-Dominguez, Reyna; Rigotti, Attilio; Fisberg, Regina Mara; Ferrari, Gerson; Fisberg, Mauro; Brenes, Juan C.Background: Women's Dietary Diversity Score (WDDS) is an indicator of dietary diversity, a key component of diet quality in women of reproductive age (WRA). Limited information is available regarding its applicability in other population groups.Objective: To examine the ability of the Minimum Dietary Diversity for Women (MDD-W) of 5-food groups cutoff to predict micronutrient adequacy in men and women 15 to 65 years old from 8 Latin American countries.Methods: We used a 24-hour recall from 9216 participants in the Latin American Study on Nutrition and Health (ELANS) to determine Dietary Diversity Score (DDS) based on the consumption of 10 food groups. The Mean Probability of Adequacy (MPA) was associated with DDS for the overall sample, for men, WRA, and women of nonreproductive age (WNRA). Sensitivity and specificity analyses were performed to determine if the 5-food groups cutoff point for MDD can be used to correctly identify men, WRA, and WNRA with adequate micronutrient adequacy (MPA >= 0.70).Results: We found a mean DDS of 4.78 +/- 1.33 and an MPA of 0.64 +/- 0.16, with 59% of participants showing a diverse diet (DDS >= 5). The 5-food groups-cutoff point showed a better balance between sensitivity and specificity predicting an MPA >= 0.70 in men, WRA, and WNRA. MPA was significantly associated with DDS in WRA and for men and WNRA, as well.Conclusion: The 5-food group MDD, originally intended to be used in WRA, performed equally well in predicting MPA >= 0.70 in men, WRA, and WNRA, and can be used as a proxy of micronutrient adequacy in Latin American population.
