A Comparison of Associations Between Self-Reported and Device-Based Sedentary Behavior and Obesity Markers in Adults: A Multi-National Cross-Sectional Study
(2022) Ferrari, Gerson; Herrera-Cuenca, Marianella; Zalcman Zimberg, Iona; Guajardo, Viviana; Gomez, Georgina; Quesada, Dayana; Rigotti, Attilio; Yadira Cortes, Lilia; Yepez Garcia, Martha; Pareja, Rossina G.; Peralta, Miguel; Marques, Adilson; Leme, Ana Carolina B.; Kovalskys, Irina; Rollo, Scott; Fisberg, Mauro
The purpose of this study was to examine the associations between self-reported and device-based measures of sedentary behavior (SB) with obesity markers in adults from Latin American countries. Sitting time and total time spent in different SBs were self-reported using two different questionnaires. Accelerometers were used to assess total sedentary time. Body mass index, waist, and neck circumferences were assessed. The highest self-reported sitting time was in Argentina, the highest total time spent in different SBs was in Brazil and Costa Rica, and the highest device-based sedentary time was observed in Peru. Neither self-reported sitting time, total time spent in different SBs or device-based sedentary time were associated with body mass index. Device-based sedentary time was positively associated with waist circumference and self-reported sitting time was positively associated with neck circumference. Caution is warranted when comparing the associations of self-reported and device-based assessments of SB with anthropometric variables.

(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, Georgina
Background: 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.
Accelerometer-Measured Daily Step Counts and Adiposity Indicators among Latin American Adults: A Multi-Country Study
(2021) Ferrari, Gerson; Marques, Adilson; Barreira, Tiago V.; Kovalskys, Irina; Gomez, Georgina; Rigotti, Attilio; Cortes, Lilia Yadira; Garcia, Martha Cecilia Yepez; Pareja, Rossina G.; Herrera-Cuenca, Marianella; Guajardo, Viviana; Leme, Ana Carolina B.; Guzman Habinger, Juan; Valdivia-Moral, Pedro; Suarez-Reyes, Monica; Ihle, Andreas; Gouveia, Elvio R.; Fisberg, Mauro
The aim of the present study was to examine the sex-related associations between accelerometer-measured daily step counts and adiposity indicators in adults from eight Latin American countries. We analyzed data from 2524 adults (aged 18-65 years) from the Latin American Study of Nutrition and Health. Device-measured daily step counts were measured by accelerometers (ActiGraph GT3X). The outcomes were body mass index (BMI; (kg/m2), waist and neck circumference (in cm). Overall, the mean of daily steps counts, BMI, waist and neck circumference were 10699.8, 27.3, 89.6, and 35.8. Weak and negative associations were observed between daily steps counts and BMI (r = -0.17; p < 0.05) and waist circumference (r = -0.16; p < 0.05); however, step counts was not associated with neck circumference. Daily steps counts were negatively associated with BMI (beta: -0.054; 95%CI: -0.077; -0.012) and waist circumference (-0.098; -0.165; -0.030) independently of age and socioeconomic level. In men, there were significant negative associations between daily steps counts with BMI (-0.075; -0.119; -0.031) and waist circumference (-0.140; -0.233; -0.048), and in women, there was no significant association with either of the body composition indicators. The findings from this study need to be examined in prospective settings that use device-measured from Latin America.
Age-related influence of the HDL receptor SR-BI on synaptic plasticity and cognition
(ELSEVIER SCIENCE INC, 2009) Chang, Eric H.; Rigotti, Attilio; Huerta, Patricio T.
Dysregulated cholesterol metabolism is a major risk factor for atherosclerosis and other late-onset disorders, such as Alzheimer's disease. The scavenger receptor, class B, type I (SR-BI) is critical in maintaining the homeostasis of cholesterol and alpha-tocopherol. SR-BI binds high-density lipoproteins (HDL) and mediates the selective transfer of cholesteryl esters and alpha-tocopherol from circulating HDL to cells. SR-BI is also involved in reverse cholesterol transport from peripheral tissues into the liver. Previous studies using SR-BI genetic knockout mice indicated that the deletion of SR-BI resulted in an accelerated onset of atherosclerosis. We hypothesized that SR-BI-dependent lipid dysregulation might disrupt brain function leading to cognitive impairment. Here, we report that very old SR-BI knockout mice show deficient synaptic plasticity (long-term potentiation) in the CA 1 region of the hippocampus. Very old SR-BI KO mice also display selective impairments in recognition memory and spatial memory. Thus, SR-BI influences neural and cognitive processes, a finding that highlights the contribution of cholesterol and alpha-tocopherol homeostasis in proper cognitive function. (C) 2007 Elsevier Inc.

Agreement Between Self-Reported and Device-Based Sedentary Time among Eight Countries: Findings from the ELANS
(2021) Ferrari, Gerson; Werneck, Andre O.; Silva, Danilo R.; Kovalskys, Irina; Gomez, Georgina; Rigotti, Attilio; Cortes, Lilia Yadira; Garcia, Martha Yepez; Liria, Maria; Herrera-Cuenca, Marianella; Zimberg, Iona Zalcman; Guajardo, Viviana; Pratt, Michael; Cristi-Montero, Carlos; Marques, Adilson; Peralta, Miguel; Bolados, Cristian Cofre; Leme, Ana Carolina B.; Rollo, Scott; Fisberg, Mauro
The purpose of this study was to analyze the agreement between self-reported and device-based sedentary time among eight countries in Latin America. As part of the Latin American Study of Nutrition and Health (ELANS), data were collected from 2524 participants (18-65 years) across eight countries. Participants reported time spent sedentary in different activities (computer use at home, videogame use, reading, sitting down to chat with friends/relatives or listening to music, speaking on the phone, watching TV, and riding in a car). Overall sitting time was assessed using a single item from the International Physical Activity Questionnaire (IPAQ). Device-based sedentary time was assessed using Actigraph GT3X accelerometers. Self-reported overall sitting time (227.1 min/day) produced the lowest values of the three assessment methods, followed by self-reported sum of different types of sedentary behavior (364.1 min/day) and device-based sedentary time (568.6 min/day). Overall, correlation coefficients and ICC varied from weak to moderate (rho: 0.25-0.39; ICC: 0.21:0.39) between self-reported sum of different types of sedentary behavior, self-reported overall sitting time, and device-based sedentary time. The Bland-Altman plots indicated low to moderate agreement between self-reported overall sitting time and device-based sedentary time by sex. Self-report measures underestimate sedentary behavior and overall sitting time when compared with device-based measures. The weak and moderate level of agreement between methods indicates that caution is required when comparing associations between different self-report and device-based measures of sedentary behavior with health outcomes.
Alcohol Contribution to Total Energy Intake and Its Association with Nutritional Status and Diet Quality in Eight Latina American Countries
(2021) Brenes, Juan Carlos; Gomez, Georgina; Quesada, Dayana; Kovalskys, Irina; Rigotti, Attilio; Cortes, Lilia Yadira; Yepez Garcia, Martha Cecilia; Liria-Dominguez, Reyna; Herrera-Cuenca, Marianella; Guajardo, Viviana; Fisberg, Regina Mara; Leme, Ana Carolina B.; Ferrari, Gerson; Fisberg, Mauro; ELANS Study Grp
Alcohol consumption is a modifiable risk factor for non-communicable diseases. This study aimed to characterize alcohol consumers at the nutritional, anthropometric, and sociodemographic levels. Data from 9218 participants from Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Peru, and Venezuela participating in "Latin American Health and Nutrition Study (ELANS)", a multi-country, population-based study, were used. Dietary intake was collected through two, 24 h recalls. Participants were classified into consumers (n = 1073) and non-alcohol consumers (n = 8145) using a cut-off criterium of >= 15 g/day of alcohol consumption calculated from the estimation of their usual daily intake. Among alcohol consumers, the mean alcohol consumption was 69.22 +/- 2.18 grams (4.6. beverages/day), contributing to 484.62 kcal, which corresponded to 16.86% of the total energy intake. We found that the risk of alcohol consumption was higher in young and middle-aged men from low and middle socioeconomic status. Argentine, Brazil, and Chile had the highest percentage of consumers, while Ecuador showed the highest alcohol consumption. Alcohol drinkers were characterized by having higher body weight and wider neck, waist, hips circumferences. Alcohol drinkers had a higher energy intake, with macronutrients providing relatively less energy at the expense of the energy derived from alcohol. Alcohol drinkers showed lower and higher consumptions of healthy and unhealthy food groups, respectively. In addition, adequacy ratios for all micronutrients assessed were lower in alcohol consumers. All these deleterious effects of alcohol on nutritional and anthropometric parameters increased with the number of alcoholic beverages consumed daily. Altogether, these findings suggest that limiting alcohol consumption can contribute to reducing the risk of obesity, metabolic syndrome, and diet-related diseases.

(2021) Herrera-Cuenca, Marianella; Kovalskys, Irina; Gerardi, Alejandro; Hernandez, Pablo; Sifontes, Yaritza; Gomez, Georgina; Yepez Garcia, Martha Cecilia; Mendez-Perez, Betty; Landaeta-Jimenez, Maritza; Pareja, Rossina; Cortes, Lilia Yadira; Rigotti, Attilio; Fisberg, Mauro; Zimberg, Iona Zalcman
Background: Latin America has experienced changes in lifestyle since 1960.Aim: The aim was to determine the prevalence of obesity and stunting among eight countries of Latin American and to identify the determinant risk factors for obesity.Subjects and Methods: Data were obtained from 9,218 participants of the Latin American Study of Nutrition and Health (ELANS), a multicenter cross-sectional study of the representative samples in eight Latin American countries. All the participants completed a standard protocol to investigate the nutrient intake and anthropometric variables (weight, height, and circumferences) analyzed by country, gender, age, and socioeconomic status.Results: The prevalence of obesity was higher in Costa Rica and Venezuela (29%) and lower in Colombia (16%), stunting was reported higher in Peru (47%) and lower in Argentina (17%), and waist and neck circumferences showed the higher values in Costa Rica (43%) and Chile (52%) and lower values in Colombia (23 and 26%).Conclusion: This study indicates an increasing trend toward overweight and obesity that are associated with lower socioeconomic status, being a woman, and concurs with inadequate intakes of calcium, which may be related to poor quality diet and in the long term could constitute risk factors for the chronic diseases and a health burden to the region.
Assessment of Diet Quality in Chilean Urban Population through the Alternate Healthy Eating Index 2010: A Cross-Sectional Study
(2019) Pinto, Victoria; Landaeta-Diaz, Leslie; Castillo, Oscar; Villarroel, Luis; Rigotti, Attilio; Echeverria, Guadalupe
Most worldwide causes of disease and death are strongly associated with dietary factors and the application of eating indexes has proved to be a useful tool to determine diet quality in populations. The aim of this study was to evaluate the diet quality in Chile through the application of the Alternate Healthy Eating Index 2010 (AHEI-2010). A representative sample (n = 879) of Chilean urban population aged 15-65 years old from the Latin American Study of Nutrition and Health (Estudio Latinoamericano de Nutricion y Salud; ELANS) was used. Dietary intake data were obtained through two 24-hour food recalls and one beverage frequency questionnaire, which were used to calculate AHEI-2010 and its association with sociodemographic and anthropometric variables. In this Chilean sample, the AHEI-2010 score was 43.7 +/- 7.8 points (mean +/- SD). Trans fats and sodium intake were the highest scoring AHEI-2010 components whereas sugar-sweetened beverages and whole grains had the lowest score. Women, older subjects, and individuals in medium-high socioeconomic levels had significantly higher mean AHEI-2010 scores. No association was found between AHEI-2010 and body mass index (BMI), or nutritional status. Conclusions: Diet quality in the Chilean urban population aged 15-65 years old is far from optimal. Thus, there is room for significant improvement of diet quality in Chile through design and implementation of public health policies, particularly in high-risk groups for chronic diseases.
Association between Active Transportation and Public Transport with an Objectively Measured Meeting of Moderate-to-Vigorous Physical Activity and Daily Steps Guidelines in Adults by Sex from Eight Latin American Countries
(2021) Herreros-Irarrazabal, Diego; Guzman-Habinger, Juan; Mahecha Matsudo, Sandra; Kovalskys, Irina; Gomez, Georgina; Rigotti, Attilio; Cortes, Lilia Yadira; Garcia, Martha Cecilia Yepez; Pareja, Rossina G.; Herrera-Cuenca, Marianella; Farias-Valenzuela, Claudio; Marques, Adilson; Leme, Ana Carolina B.; Fisberg, Mauro; Drenowatz, Clemens; Ferrari, Gerson
This study aimed to examine the associations between active transportation and public transport and the objectively measured meeting of moderate-to-vigorous physical activity (MVPA) and steps per day guidelines in adults by sex from eight Latin American countries. As part of the Latin American Study of Nutrition and Health (ELANS), data were collected from 2524 participants aged 18-65 years. MVPA and steps per day were evaluated using Actigraph GT3X accelerometers. The mode of transportation, its frequency and duration were collected using a self-reported questionnaire. The average time dedicated to active transportation was 12.8 min/day in men (IQR: 2.8-30.0) and 12.9 min/day in women (IQR: 4.3-25.7). A logistic regression analysis was conducted, showing that active transportation (>= 10 min) was associated with higher odds of meeting MVPA guidelines (men: OR: 2.01; 95%CI: 1.58-2.54; women: OR: 1.57; 95%CI: 1.25-1.96). These results show a greater association when considering active transportation plus public transport (men: OR: 2.98; 95%CI: 2.31-3.91; women: OR: 1.82; 95%CI: 1.45-2.29). Active transportation plus public transport was positively associated with meeting steps per day guidelines only in men (OR: 1.55; 95%CI: 1.15-2.10). This study supports the suggestion that active transportation plus public transport is significantly associated with meeting the MVPA and daily steps recommendations.

Association between serum sphingolipids and eudaimonic well-being in white US adults
(2021) Berkowitz, Loni; Henriquez, Marcela P.; Salazar, Cristian; Rojas, Eric; Echeverria, Guadalupe; Love, Gayle D.; Rigotti, Attilio; Coe, Christopher L.; Ryff, Carol D.
Emerging research has linked psychological well-being with many physiological markers as well as morbidity and mortality. In this analysis, the relationship between components of eudaimonic well-being and serum sphingolipids levels was investigated using data from a large national survey of middle-aged American adults (Midlife in the United States). Health behaviors (i.e., diet, exercise, and sleep) were also examined as potential mediators of these relationships. Serum levels of total ceramides-the main molecular class of sphingolipids previously associated with several disease conditions-were inversely linked with environmental mastery. In addition, significant correlations were found between specific ceramide, dihydroceramide, and hexosylceramides species with environmental mastery, purpose in life, and self-acceptance. Using hierarchical regression and mediation analyses, health behaviors appeared to mediate these associations. However, the link between ceramides and environmental mastery was partially independent of health behaviors, suggesting the role of additional mediating factors. These findings point to sphingolipid metabolism as a novel pathway of health benefits associated with psychological well-being. In particular, having a sense of environmental mastery may promote restorative behaviors and benefit health via improved blood sphingolipid profiles.

P.; Bezerra Goncalves, Priscila; Alberico, Claudia; Ferrari, Gerson Luis de Moraes; Previdelli, Agatha Nogueira; Aparecida Grande de Franca, Natasha
Introduction: the failure to eat breakfast has been associated with weight gain, a lower level of physical activity, and poor diet quality.
Cholecystectomy increases hepatic triglyceride content and very-low-density lipoproteins production in mice
(WILEY, 2011) Amigo, Ludwig; Husche, Constanze; Zanlungo, Silvana; Luetjohann, Dieter; Arrese, Marco; Miquel, Juan F.; Rigotti, Attilio; Nervi, Flavio
Background & aims: Bile acid (BA) pool size remains unchanged after cholecystectomy (XGB) but it circulates faster, exposing the enterohepatic system to an increased flux of BA. Triglyceride (TG) and BA metabolisms are functionally inter-related. We investigated whether ablation of the gallbladder (GB) modifies hepatic TG metabolism. Methods: Male mice were subjected to XGB and fed a normal diet. In some experiments, mice received a 1% nicotinic acid diet to block lipolysis. Parameters of BA and TG metabolism, and microsomal triglyceride transfer protein (MTTP) activity were measured 1-2 months after XGB. Serum parameters, hepatic lipids and mRNA expression of genes of lipid metabolism were determined. Results: BA pool size and synthesis were normal, but biliary BA secretion doubled during the diurnal light phase in XGB mice. Serum and hepatic TG concentrations increased 25% (P < 0.02), and hepatic very-low-density lipoproteins (VLDL)-TG and apoB-48 productions increased 15% (P < 0.03) and 50% (P < 0.01), respectively, after XGB. Feeding a 1% nicotinic acid did normalize VLDL production. MTTP activity increased 15% (P < 0.005) after XGB. Hepatic free fatty acid (FFA) synthesis and content, and mRNA levels of lipid metabolism-related genes remained normal in XGD mice. Conclusions: XGB increased serum and hepatic TG levels, and VLDL production, which were restored to normal by nicotinic acid. The results suggest that FFA flux from adipose tissue to the liver is increased in XGB mice. They support the hypothesis that the GB has a role in the regulation of hepatic TG metabolism and that XGB may favour the accumulation of fat in the liver.

Dietary protein intake is vital to life. Here we sought to characterize dietary sources of protein in eight Latin American countries. Survey data were collected for Estudio Latinoamericano de Nutricion y Salud (ELANS); participants were from Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Peru, and Venezuela (n = 9218, 15-65 years old). The primary aim of this analysis was to quantify per-person daily protein consumption by country and sociodemographic factors. Secondary aims: to quantify proportional intake of proteins by source, amount and processing, and to determine the adequacy of protein/essential amino acid intake. Younger groups (adolescents 15-19 years, adults 20-33 years) had the highest intake of proteins; middle-aged adults (34-49 years) had a lower intake, and older adults (50-65 years) had a strikingly lower intake. Protein consumption was higher in men than women. Animal proteins comprised nearly 70% of total daily protein intake in Argentina and Venezuela, contrasting with <60% in Peru, Chile, and Costa Rica. Brazil and Venezuela showed the highest protein intake within the highest education level. The higher the socioeconomic level, the higher the protein intake, except for Argentina, Chile, and Peru. Proportional intake of animal- and plant-based protein generally reflected the food availability by country. This study presents a pre-pandemic regional baseline and offers a perspective for future studies of changes related to government policies, climate, and dietary practices.

(2021) Liria-Dominguez, Reyna; Perez-Albela, Marcela; Vasquez, Maria-Paz; Gomez, Georgina; Kovalskys, Irina; Fisberg, Mauro; Cortes, Lilia Yadira; Yepez Garcia, Martha Cecilia; Herrera-Cuenca, Marianella; Rigotti, Attilio; Ferrari, Gerson; Pareja, Rossina G.
Neck circumference (NC) is being used to identify the risk of chronic diseases. There is a high prevalence of overweight and obesity in Latin America, and neck circumference is a simple and practical measurement to assess this, especially in primary health centers. We analyzed the correlation between the NC anthropometric indicator and other anthropometric measurements such as BMI and waist circumference (WC) in eight Latin American cities. We applied Pearson's correlation to identify the correlate NC with the other anthropometric variables stratified by sex; the sensitivity (Se) and specificity (Sp) by sex were evaluated according to the cut-off established with the Youden Index. The strongest correlations between NC and WC were found when stratified by sex (women: r = 0.71; men: r = 0.69, respectively) followed by the correlation between NC and BMI (r = 0.65, both sex). NC cut-off points of 39.0 cm in men and 32.9 cm in women identified those individuals with an increased WC and 39.8 and 33.7 cm, respectively, for a substantial increase in WC. For BMI & GE; 25.0 kg/m(2) for men, the cut-off point was 37.5 cm, and for women, it was 33.1 cm, and for BMI & GE; 30 kg/m(2), the cut-off points were 39.2 and 34.2 cm, for men and women, respectively. Conclusion: NC proved to be a useful, practical, and inexpensive tool that can be used to identify, evaluate, and monitor overweight and obese individuals.
Developing a cooperative multicenter study in Latin America: Lessons learned from the Latin American Study of Nutrition and Health Project
(2017) Fisberg, Mauro; Kovalskys, Irina; Gomez Salas, Georgina; Pareja Torres, Rossina Gabriella; Yepez Garcia, Martha Cecilia; Cortes Sanabria, Lille Yadira; Herrera-Cuenca, Marianella; Rigotti, Attilio; Guajardo, Viviana; Zimberg, Ione Zalcman; Previdelli, Agatha Nogueira; Moreno, Luis A.; Pratt, Michael; Koletzko, Berthold; Tucker, Katherine L.
This report examines the challenges of conducting a multicenter, cross-sectional study of countries with diverse cultures, and shares the lessons learned. The Latin American Study of Nutrition and Health (ELANS) was used as a feasibility study involving the most populous cities of eight countries in Latin America (Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Peru, and Venezuela) in 2014-2015, about 40% of the population of the Americas. The target sample included 9 000 individuals, 15-65 years of age, and was stratified by geographic location (only urban areas), gender, age, and socioeconomic status.
Dietary Diversity and Micronutrients Adequacy in Women of Childbearing Age: Results from ELANS Study
(2020) Gomez, Georgina; Previdelli, Agatha Nogueira; Fisberg, Regina Mara; Kovalskys, Irina; Fisberg, Mauro; Herrera-Cuenca, Marianella; Cortes Sanabria, Lilia Yadira; Yepez Garcia, Martha Cecilia; Rigotti, Attilio; Reyna Liria-Dominguez, Maria; Guajardo, Viviana; Quesada, Dayana; Murillo, Ana Gabriela; Carlos Brenes, Juan
Dietary diversity, an important component of diet quality, is associated with an increased probability of adequate micronutrient intake. Women of childbearing age (WCA) are particularly vulnerable to micronutrient inadequacy. The Minimum Dietary Diversity for Women (MDD-W) has been used widely as a proxy measurement of micronutrient adequacy. This study aimed to assess the association between MDD-W and nutrients adequacy among WCA of eight Latin American countries. Nutrient intakes from 3704 WCA were analyzed with two 24-hour dietary recalls. Dietary diversity was calculated based on ten food groups with a cut-off point of intake >= 5 groups. The mean dietary diversity score was 4.72 points, and 57.7% of WCA achieved MDD-W. Vitamin D and E showed a mean Nutrient Adequacy Ratio (NAR) of 0.03 and 0.38, respectively. WCA with a diverse diet (MDD-W > 5) reported a significantly higher intake of most micronutrients and healthy food groups with less consumption of red and processed meats and sugar-sweetened beverages. MDD-W was significantly associated with the mean adequacy ratio (MAR) of 18 micronutrients evaluated. Nevertheless, even those women with a diverse diet fell short of meeting the Estimated Average Requirements (EAR) for vitamins D and E. MDD-W is an appropriate tool to evaluate micronutrients adequacy in WCA from Latin America, showing that women who achieved the MDD-W reported higher adequacy ratios for most micronutrients and an overall healthier diet.
Dispositional Mindfulness Reduces Burnout and Promotes Flourishing in Medical Students: a Two-Wave Latent Change Score Model
(2022) Zuniga, Denisse; Torres-Sahli, Manuel; Rigotti, Attilio; Pedrals, Nuria; Echeverria, Guadalupe; Padilla, Oslando; Lagos, Alejandra; McColl, Peter; Trucco, Olivia; Cisternas, Marcela; Gonzalez, Carolina; Bogado, Justo; Moraga, Ana Maria; Altamirano, Patricio; Duran, Esperanza; Mansilla, Marcela; Berrios, Carolina; Epstein, Ronald; Bitran, Marcela
Objectives Many studies document the high prevalence of burnout among medical students. This syndrome may lead to depression, suicidal ideation, and increased academic dropout. However, there is a scarcity of evidence-based interventions to prevent it. The aim of this longitudinal study was to identify factors that may reduce students' burnout and foster their well-being, and upon which effective interventions can be developed. Methods A total of 1,117 medical students from eight Chilean universities were asked to complete a set of validated scales in 2015 and 2 years later, in 2017. The measures included distress, burnout, positive mental health, academic engagement, and dispositional mindfulness. Using logistic regressions and a two-wave latent change score model, the predictive power of these variables on burnout and flourishing (an optimal state of mental health) was studied, as well as their covariance across time. Results In total, 639 (57.2%) students answered the questionnaires in T1 and T2; 54.4% reported burnout in T1 and 56.2% in T2. Levels of dispositional mindfulness (the ability to pay attention to one's sensations, thoughts, and emotions in everyday life) predicted lower probabilities of burning out at 2 years, whereas having experienced burnout in T1 doubled these odds. Dispositional mindfulness, academic engagement, and flourishing at T1 predicted greater odds of flourishing 2 years later, while depression decreased these odds. Conclusions Dispositional mindfulness was the most powerful predictive factor of students' burnout and flourishing. As dispositional mindfulness can be nurtured through practice, incorporating mindfulness training into undergraduate medical programs may help reduce burnout and promote students' well-being as health professionals.
