The urban built environment and adult BMI, obesity, and diabetes in Latin American cities.

Latin America is the world's most urbanized region and its heterogeneous urban development may impact chronic diseases. Here, we evaluated the association of built environment characteristics at the sub-city -intersection density, greenness, and population density- and city-level -fragmentation and isolation- with body mass index (BMI), obesity, and type 2 diabetes (T2D). Data from 93,280 (BMI and obesity) and 122,211 individuals (T2D) was analysed across 10 countries. Living in areas with higher intersection density was positively associated with BMI and obesity, whereas living in more fragmented and greener areas were negatively associated. T2D was positively associated with intersection density, but negatively associated with greenness and population density. The rapid urban expansion experienced by Latin America provides unique insights and vastly expand opportunities for population-wide urban interventions aimed at reducing obesity and T2D burden.

Are Women's Empowerment and Income Inequality Associated with Excess Weight in Latin American Cities?

While income gradients and gender inequalities in excess weight have been noted elsewhere, data from Latin American cities is lacking. We analyzed gender-specific associations between city-level women's empowerment and income inequality with individual-level overweight/obesity, assessing how these associations vary by individual education or living conditions within cities in Latin America. Data came from national surveys and censuses, and was compiled by the SALURBAL project (Urban Health in Latin America). The sample included 79,422 individuals (58.0% women), living in 538 sub-cities, 187 cities, and 8 countries. We used gender-stratified Poisson multilevel models to estimate the Prevalence Rate Ratios (PRR) for overweight/obesity (body mass index ≥ 25 kg/m2) per a unit change in city-level women's empowerment (proxied by a score that measures gender inequalities in employment and education) and income inequality (proxied by income-based Gini coefficient). We also tested whether individual education or sub-city living conditions modified such associations. Higher city labor women's empowerment (in women) and higher city Gini coefficient (in men) were associated with a lower prevalence of overweight/obesity (PRR = 0.97 (95%CI 0.94, 0.99) and PRR = 0.94 (95%CI 0.90, 0.97), respectively). The associations varied by individual education and sub-city living conditions. For labor women's empowerment, we observed weakened associations towards the null effect in women with lower education and in residents of sub-cities with worse living conditions (men and women). For the Gini coefficient, the association was stronger among men with primary education, and a negative association was observed in women with primary education. Our findings highlight the need for promoting equity-based policies and interventions to tackle the high prevalence of excess weight in Latin American cities.

El cuidado prenatal y los determinantes sociales: estudio ecológico en Argentina / Prenatal care and social determinants: ecological study in Argentina

Resumen Introducción: el cuidado prenatal es un aspecto clave de salud pública, con gran impacto en la salud materna y perinatal, así como en otras etapas del ciclo vital. Sus características pueden ser variables entre y al interior de los países, y vincularse a ciertos determinantes sociales. El objetivo de este estudio fue identificar escenarios sociosanitarios del cuidado prenatal y analizar asociaciones entre determinantes sociales e indicadores sintéticos seleccionados del cuidado prenatal en Argentina (2010-2018). Metodología: se desarrolló un estudio ecológico de grupos múltiples (n = 24 jurisdicciones). Los datos se obtuvieron a partir de fuentes secundarias: última información disponible del Sistema Informático Perinatal (2018) y censo nacional (2010). Se realizó un análisis de conglomerados de tipo jerárquico y aglomerativo (método de Ward). Se ilustró la distribución espacial de los escenarios identificados y se valoraron las diferencias entre ellos mediante la prueba ANOVA. Para estimar asociaciones entre indicadores sociales e indicadores del cuidado prenatal se propusieron modelos de regresión lineal. Resultados: se identificaron cinco escenarios sociosanitarios del cuidado prenatal, que revelan heterogeneidades en la distribución de indicadores de cuidado prenatal y sociales a nivel provincial. Además, el porcentaje de hogares en situación de pobreza presentó una asociación directa, en tanto el índice de desarrollo humano y la esperanza de vida al nacer una inversa con el control prenatal insuficiente. Conclusiones: existen diferentes escenarios sociosanitarios del cuidado prenatal en Argentina y ciertas características sociales de los contextos en que residen las personas podrían subyacer a su configuración.

Abstract Introduction: the prenatal care is a key aspect in public health, with great impact in maternal and perinatal health, as well as in other stages of the life cycle. The features of the prenatal care could be variable between and within countries, and be related to social determinants. The aim of this study was to identify socio-sanitary scenarios of prenatal care, and to analyze associations between social determinants and selected synthetic indicators of prenatal care in Argentina (2010-2018). Methodology: A multi-group ecological study (n=24 jurisdictions) was developed. The data were obtained from secondary sources: the latest available data of the Perinatal Informatics' System (2018) and national census (2010). A hierarchical and agglomerative cluster analysis was carried out (Wards method). The spatial distribution of the scenarios was illustrated by a map. ANOVA test was applied to assess the differences between the identified scenarios. To estimate associations between social indicators and indicators of prenatal care, linear regression models were applied. Results: five socio-sanitary scenarios of prenatal care were identified, which reveal heterogeneities in the distribution of prenatal and social care indicators. In addition, the percentage of households living in poverty presented a direct association, and the human development index and life expectancy at birth an inverse association with insufficient prenatal care. Conclusions: different socio-sanitary scenarios exist in Argentina, and some social characteristics of the contexts in which people live might underlie its configuration.

[Comparison of a community-based nutritional intervention and a conventional nutritional intervention in Mayan communities in Mexico]. / Comparación de una intervención nutricional basada en la comunidad y una intervención nutricional convencional en localidades mayas de México.

Poor nutritional conditions persist in many Mayan communities in Yucatán, Mexico, even though various programs have been implemented. The study aimed to compare the effects of a community-based nutritional intervention with an intercultural focus versus a conventional nutritional intervention on body mass index (BMI) and diet in women in Mayan communities in Yucatán. The sample included adult women with BMI ≥ 25kg/m2 from neighboring rural Mayan villages. Both interventions lasted three months with 11 sessions and followed the prevailing guidelines. The community-based intervention used an intercultural tool called Good Mayan Food [Plato del Bien Comer Maya], besides strategies designed according to information obtained from a prior qualitative study phase using interviews. The group that received the community-based intervention (n = 7), compared to the conventional intervention group (n = 9), showed larger decreases in BMI (-0.58 ± 0.70 kg/m2 and +0.27 ± 0.64kg/m2; p = 0.042), waist circumference (-2.15 ± 2.60 cm and -0.50 ± 0.75 cm; p = 0.042), and consumption of fats (-53.23 ± 21.92 grams and -7.34 ± 25.77 grams; p = 0.004), as well as higher increases in weekly consumption of some local foods such as nance fruit (p = 0.012), tamarind (p = 0.001), and chili peppers (p = 0.004). The community-based intervention was the only one to show a significant decrease in daily calorie intake (baseline: 2,067 ± 91 kcal/day, at three months: 1,474 ± 31 kcal/day; p = 0.018), and both groups showed decreases in the consumption of ultra-processed foods, but without significant differences between the two groups. The community-based intervention group showed better results than the conventional intervention group.

As más condições nutricionais em muitas localidades maias de Yucatán (México) persistem apesar da implementação de diversos programas. O objetivo era comparar os impactos de uma intervenção nutricional baseada na comunidade com enfoque intercultural (INBC) e uma intervenção nutricional convencional (INC), sobre o índice de massa corporal (IMC) e a dieta de mulheres de localidades maias de Yucatán. Foram incluídas mulheres adultas com IMC ≥ 25kg/m2 de duas pequenas localidades rurais maias vizinhas. Ambas as intervenções duraram três meses e contaram com 11 sessões, conforme as normas vigentes; na INBC, foi utilizada a ferramenta intercultural denominada Prato de Comer Bem Maia [Plato del Bien Comer Maya], além de estratégias adicionais idealizadas com base em dados obtidos em uma fase prévia de estudo qualitativo com entrevistas. Em comparação com o grupo com a INC (n = 9), o grupo com a INBC (n = 7) teve maior diminuição de IMC (-0,58 ± 0,70 kg/m2 e +0,27 ± 0,64 kg/m2; p = 0,042), da circunferência abdominal (-2,15 ± 2,60 cm y -0,50 ± 0,75 cm; p = 0,042) e do consumo de gorduras (-53,23 ± 21,92 gramas y -7,34 ± 25,77 gramas; p = 0,004), bem como um aumento maior das frequências semanais de consumo de alguns alimentos locais como o murici (p = 0,012), o tamarindo (p = 0,001) e pimenta (p = 0,004). A INBC foi a única a apresentar uma diminuição significativa do consumo diário de calorias (inicial: 2.067 ± 91 kcal/dia, após três meses: 1.474 ± 31 kcal/dia; p = 0.018). Houve em ambos os grupos redução equivalente do consumo de alimentos ultraprocessados; o grupo com a INBC obteve melhores resultados que o grupo com a INC.

Determinantes sociales y de género del exceso de peso en la adultez en contextos de pobreza urbana en Córdoba, Argentina, 2019 / Social and gender determinants of excess weight in the adulthood in contexts of urban poverty in Córdoba, Argentina, 2019

INTRODUCCIÓN: La clase social y el género se vinculan con la malnutrición por exceso. Sin embargo, existe aún escasa evidencia al respecto en contextos de pobreza urbana de Córdoba. El objetivo de este trabajo fue analizar los determinantes sociales individuales de la ocurrencia de sobrepeso, obesidad y obesidad abdominal en la población adulta por género en contextos de pobreza de la ciudad de Córdoba en 2019. MÉTODOS: Se realizó un estudio epidemiológico observacional de corte transversal, con una muestra aleatoria (n=380) de personas adultas usuarias de un hospital público. Se efectuaron mediciones antropométricas y una entrevista sobre características sociodemográficas, socioeconómicas, de género y de salud. Se estimaron modelos de regresión logística múltiple estratificados por género. RESULTADOS: Las mujeres solteras, separadas o viudas tenían menor probabilidad de sobrepeso (OR 0,40; IC 95%: 0,18-0,87) y las mujeres desocupadas (OR 0,27; IC 95%: 0,08-0,87 ) de obesidad abdominal. Los varones de nivel socioeconómico medio o bajo presentaban menor probabilidad de sobrepeso (OR 0,21; IC 95%: 0,05-0,76), y los que dedicaban mayor tiempo al trabajo no remunerado tenían menor probabilidad de presentar obesidad (OR 0,43; IC 95%: 0,20-0,89). DISCUSIÓN: La malnutrición por exceso en contextos de pobreza de Córdoba está relacionada con determinantes sociales y de género, y es diferente en varones y mujeres.

Urban social determinants of non-communicable diseases risk factors in Argentina.

We examined associations of individual-, neighborhood- and city-level education -as proxies of SES at different levels-, with diabetes, hypertension, obesity, smoking and binge drinking (non-communicable disease risk factors -NCD/RF) among Argentinian adults. We estimated mixed models based on 21,415 individuals from the 2013 National Survey of Risk Factors, living in 2,698 neighborhoods and 33 cities. Gradients by individual-level education differed by gender and NCD/RF, and some were modified by city education. In addition, we identified contextual effects of neighborhood and city education on some NCD/RF. Urban efforts to tackle NCD/RF in Argentina should be context- and gender-sensitive, and mainly focused on socially disadvantaged groups.

Intraurban socioeconomic inequalities in life expectancy: a population-based cross-sectional analysis in the city of Córdoba, Argentina (2015-2018).

OBJECTIVES: To evaluate variability in life expectancy at birth in small areas, describe the spatial pattern of life expectancy, and examine associations between small-area socioeconomic characteristics and life expectancy in a mid-sized city of a middle-income country. DESIGN: Cross-sectional, using data from death registries (2015-2018) and socioeconomic characteristics data from the 2010 national population census. PARTICIPANTS/SETTING: 40 898 death records in 99 small areas of the city of Córdoba, Argentina. We summarised variability in life expectancy at birth by using the difference between the 90th and 10th percentile of the distribution of life expectancy across small areas (P90-P10 gap) and evaluated associations with small-area socioeconomic characteristics by calculating a Slope Index of Inequality in linear regression. PRIMARY OUTCOME: Life expectancy at birth. RESULTS: The median life expectancy at birth was 80.3 years in women (P90-P10 gap=3.2 years) and 75.1 years in men (P90-P10 gap=4.6 years). We found higher life expectancies in the core and northwest parts of the city, especially among women. We found positive associations between life expectancy and better small-area socioeconomic characteristics, especially among men. Mean differences in life expectancy between the highest versus the lowest decile of area characteristics in men (women) were 3.03 (2.58), 3.52 (2.56) and 2.97 (2.31) years for % adults with high school education or above, % persons aged 15-17 attending school, and % households with water inside the dwelling, respectively. Lower values of % overcrowded households and unemployment rate were associated with longer life expectancy: mean differences comparing the lowest versus the highest decile were 3.03 and 2.73 in men and 2.57 and 2.34 years in women, respectively. CONCLUSION: Life expectancy is substantially heterogeneous and patterned by socioeconomic characteristics in a mid-sized city of a middle-income country, suggesting that small-area inequities in life expectancy are not limited to large cities or high-income countries.

What Do We Know about Inequalities in NAFLD Distribution and Outcomes? A Scoping Review.

With prevalence high and rising given the close relationship with obesity and diabetes mellitus, non-alcoholic fatty liver disease (NAFLD) is progressively becoming the most common chronic liver condition worldwide. However, little is known about the health inequalities in NAFLD distribution and outcomes. This review aims to analyze health inequalities in NAFLD distribution globally and to assess the health disparities in NAFLD-related outcomes. We conducted a scoping review of global health inequalities in NAFLD distribution and outcomes according to gender/sex, ethnicity/race, and socioeconomic position from PubMed's inception to May 2021. Ultimately, 20 articles were included in the review, most (75%) of them carried out in the United States. Males were found to have a higher NAFLD prevalence (three articles), while available evidence suggests that women have an overall higher burden of advanced liver disease and complications (four articles), whereas they are less likely to be liver-transplanted once cirrhosis develops (one article). In the US, the Hispanic population had the highest NAFLD prevalence and poorer outcomes (seven articles), whereas Whites had fewer complications than other ethnicities (two articles). Patients with low socioeconomic status had higher NAFLD prevalence (four articles) and a higher likelihood of progression and complications (five articles). In conclusion, globally there is a lack of studies analyzing NAFLD prevalence and outcomes according to various axes of inequality through joint intersectional appraisals, and most studies included in our review were based on the US population. Available evidence suggests that NAFLD distribution and outcomes show large inequalities by social group. Further research on this issue is warranted.

[Profiles of epidemiological-nutritional transition and burden of morbimortality from COVID-19 in Argentina: an ecological study]. / Perfiles de transición epidemiológica-nutricional y carga de morbi-mortalidad por COVID-19 en Argentina: un estudio ecológico.

The study aimed to identify epidemiological-nutritional profiles in Argentina and to compare the burden of morbimortality from COVID-19. A multigroup ecological study was conducted with 24 geographic units in Argentina. We estimated the percent change from 2005 to 2018 in indicators of the epidemiological-nutritional transition and sociodemographic indicators according to geographic unit. We performed principal components analysis and hierarchical cluster analysis to identify geographic groupings to define profiles in the epidemiological-nutritional transition. By group, we calculated summary measures of COVID-19 cumulative incidence (CI), mortality, and case fatality (epidemiological week 50), establishing comparisons via Student's t test. Three profiles were identified: (1) reemergence of infectious diseases, (2) persistence of cardiovascular diseases despite social, health, and lifestyle improvements, and (3) consolidation of the triad obesity-sedentarism-cardiometabolic diseases. Mean COVID-19 cumulative incidence and mortality were higher in provinces with profile 1 compared to profile 2 (CI: p = 0.0159; mortality: p = 0.0187) and profile 3 (CI: p = 0.0205). Case-fatality was higher in profile 3, which includes provinces with more unfavorable socioeconomic conditions, showing significant differences from profile 2 (p=0.0307). In conclusion, there are distinct epidemiological-nutritional profiles in Argentina which tend to differ in terms of their COVID-19 epidemiological situation. Strategies to fight COVID-19 should consider the underlying epidemiological, nutritional, and sociodemographic characteristics.

El objetivo de este trabajo fue identificar perfiles epidemiológico-nutricionales en Argentina, y comparar su carga de morbi-mortalidad por COVID-19. Se condujo un estudio ecológico multigrupal (24 unidades geográficas de Argentina). Se estimó el porcentaje de cambio 2005-2018 de indicadores de transición epidemiológica-nutricional, y sociodemográficos por unidad geográfica. Se condujo un análisis de componentes principales y análisis de clúster jerárquico para identificar agrupamientos geográficos que definan perfiles de transición epidemiológica-nutricional. Por grupo, se calcularon medidas resumen de incidencia acumulada (IA), mortalidad y tasa de letalidad por COVID-19 (semana epidemiológica 50), estableciendo comparaciones mediante prueba t de Student. Se identificaron tres perfiles denominados: (1) reemergencia de enfermedades infecciosas, (2) persistencia de enfermedades cardiovasculares con mejoras sociosanitarias y en estilos de vida, y (3) consolidación de la tríada obesidad-sedentarismo-enfermedades cardiometabólicas. La IA y mortalidad por COVID-19 promedio fue mayor en provincias con perfil 1, en comparación con el perfil 2 (IA: p = 0,0159; mortalidad: p = 0,0187) y el perfil 3 (IA: p = 0,0205). La letalidad resultó mayor en el perfil 3, que aglomera provincias con situación socioeconómica más desfavorable, estimándose diferencias significativas respecto al perfil 2 (p = 0,0307). En conclusión, existen distintos perfiles epidemiológico-nutricionales en Argentina, que tienden a diferenciarse en su situación epidemiológica de COVID-19. Las estrategias contra COVID-19 deberían considerar las características epidemiológico-nutricionales y sociodemográficas de base.

Urban social environment and low birth weight in 360 Latin American cities.

OBJECTIVE: Using data compiled by the SALURBAL project (Urban Health in Latin America; 'Salud Urbana en América Latina') we quantified variability in low birth weight (LBW) across cities in Latin America, and evaluated the associations of socio-economic characteristics at various levels (maternal, sub-city and city) with the prevalence of LBW. METHODS: The sample included 8 countries, 360 cities, 1321 administrative areas within cities (sub-city units) and birth registers of more than 4.5 million births for the year 2014. We linked maternal education from birth registers to data on socioeconomic characteristics of sub-cities and cities using the closest available national population census in each country. We applied linear and Poisson random-intercept multilevel models for aggregated data. RESULTS: The median prevalence of city LBW by country ranged from a high of 13% in Guatemala to a low of 5% in Peru (median across all cities was 7.8%). Most of the LBW variability across sub-cities was between countries, but there were also significant proportions between cities within a country, and within cities. Low maternal education was associated with higher prevalence of LBW (Prevalence rate ratios (PRR) for less than primary vs. completed secondary or more 1.12 95% CI 1.10, 1.13) in the fully adjusted model. In contrast, higher sub-city education and a better city social environment index were independently associated with higher LBW prevalence after adjustment for maternal education and age, city population size and city gross domestic product (PRR 1.04 95% CI 1.03, 1.04 per SD higher sub-city education and PRR 1.02 95% CI 1.00, 1.04 per SD higher SEI). Larger city size was associated with a higher prevalence of LBW (PRR 1.06; 95% CI 1.01, 1.12). CONCLUSION: Our findings highlight the presence of heterogeneity in the distribution of LBW and the importance of maternal education, local and broader social environments in shaping LBW in urban settings of Latin America. Implementing context-sensitive interventions guided to improve women's education is recommended to tackle LBW in the region.

Percepción de riesgo ante el coronavirus en la primera fase de la pandemia en Argentina / Perception of risk facing coronavirus in the first phase of the pandemic in Argentina / Percepção de risco perante o coronavírus na primeira fase da pandemia na Argentina

Resumen Objetivo. Analizar los factores asociados a la percepción de riesgo de coronavirus en la primera fase de la pandemia en Argentina. Métodos. Se desarrolló un estudio transversal en población adulta (n=992) argentina. En marzo 2020 se aplicó un cuestionario online de la Organización Mundial de la Salud adaptado a Argentina. Se estimó la asociación entre la percepción de probabilidad de contagio y de severidad en caso de contagio, y sentimientos en relación al coronavirus, autoeficacia y búsqueda de información, mediante modelos de regresión lineal múltiple. Resultados. La percepción de riesgo frente al coronavirus en la primera fase de la pandemia fue moderada. Sin embargo, la proporción de personas que indicó puntuaciones altas fue mucho mayor en la percepción de severidad, comparado con la percepción de probabilidad de contagio. La percepción de probabilidad de contagio fue menor a mayor percepción de lejanía del virus y a mayor frecuencia de búsqueda de información. La percepción de severidad en caso de contagio se asoció positivamente con la frecuencia de búsqueda de información. En cambio, se asoció inversamente con la percepción de lejanía del virus y la autoeficacia. Conclusiones. Existen diferentes factores tanto emocionales como sociales asociados a la percepción de contagio y de severidad en Argentina. Esta complejidad debería considerarse en el diseño de políticas públicas para la prevención de COVID-19.

Abstract Objective: to analyze the factors associated with the perception of risk of coronavirus in the first phase of the pandemic in Argentina. Methods: a cross-sectional study was carried out in the Argentine adult population (n = 992). An online survey of the World Health Organization adapted to Argentina was applied in March-2020. The association between the perception of probability of contagion and severity in case of contagion and feelings related to the coronavirus, self-efficacy and health, were estimated using multiple linear regression models. Results: The perception of risk facing the first phase of the pandemic was moderate. However, the proportion of people who indicated high scores in the perception of severity was much higher compared to the perception of probability of contagion. The perception of probability of contagion was lower at greater perception of remoteness of the virus and it was greater at a higher frequency of information search. The perception of severity in case of contagion was positively associated with frequency of information search. Instead, it was inversely associated with the perception of remoteness of the virus and self-efficacy. Conclusions: There are different social and emotional factors associated with the perception of contagion and severity of coronavirus in Argentina. This complexity should be considered in the design of public policies for the prevention of COVID-19.

Resumo Objetivo. Analisar os fatores associados à percepção de risco de coronavírus na primeira fase da pandemia na Argentina. Métodos. Desenvolveu-se um estudo transversal em população adulta (n=992) na Argentina. Em março de 2020 foi aplicado um questionario online da Organização Mundial da Saúde adaptado para a Argentina. Estimouse a associação entre a percepção de probabilidade de contágio e da severidade no caso de contágio, e sentimentos em relação ao coronavírus, auto-eficácia e busca de informação, mediante modelos de regressão linear múltipla. Resultados. A percepção de risco frente ao coronavírus na primeira fase da pandemia foi moderada. Entretanto, a proporção de pessoas que indicou pontuações altas foi muito maior na percepção de severidade, comparado com a percepção de probabilidade de contágio. A percepção de probabilidade de contágio foi menor quanto maior a percepção de distância do vírus e a maior frequência de busca de informação. A percepção de severidade no caso de contágio é associada positivamente à frequência de busca de informação; por outro lado é associada inversamente à percepção de distância do vírus e a auto-eficácia. Conclusões. Existem diferentes fatores tanto emocionais como sociais associados à percepção de contágio e de severidade na Argentina. Esta complexidade deveria ser considerada no planejamento de políticas públicas para a prevenção da COVID-19.

The Inflammatory Potential of Diet is Associated with Breast Cancer Risk in Urban Argentina: A Multilevel Analysis.

Dietary patterns have been associated with breast cancer (BC) in Argentina. However, little evidence exists relating the inflammatory potential of diet and BC in Latin American countries and how this may relate to rurality.The aim of the present study was to evaluate the association between the Dietary Inflammatory Index (DII®) and BC considering urbanization contexts in Córdoba, Argentina.A frequency-matched case-control study (317 BC cases, 526 controls) was conducted from 2008 through 2016. DII scores were computed based on dietary intake assessed by a validated food frequency questionnaire. Multi-level logistic regression models were fit to evaluate the association between DII and BC, following adjustment for age, body mass index, age at menarche, number of children, smoking habits, socio-economic status and family history of BC as first-level covariates and urbanization level as the contextual variable.Increasing DII score showed significant positive associations with BC risk (ORtertile3vs.tertile1 1.34; 95%CI 1.05, 1.70). The association was stronger in overweight and obese women (ORtertile3vs.tertile1 1.98; 95%CI 1.86, 2.10). The DII effect on BC was higher with increased urbanization.A pro-inflammatory diet, reflected by higher DII scores, was positively associated with BC, especially in overweight women and with increased urbanization.

Perfiles de transición epidemiológica-nutricional y carga de morbi-mortalidad por COVID-19 en Argentina: un estudio ecológico / Profiles of epidemiological-nutritional transition and burden of morbimortality from COVID-19 in Argentina: an ecological study / Perfis de transição epidemiológica-nutricional e carga de morbimortalidade por COVID-19 na Argentina: um estudo ecológico

Resumen: El objetivo de este trabajo fue identificar perfiles epidemiológico-nutricionales en Argentina, y comparar su carga de morbi-mortalidad por COVID-19. Se condujo un estudio ecológico multigrupal (24 unidades geográficas de Argentina). Se estimó el porcentaje de cambio 2005-2018 de indicadores de transición epidemiológica-nutricional, y sociodemográficos por unidad geográfica. Se condujo un análisis de componentes principales y análisis de clúster jerárquico para identificar agrupamientos geográficos que definan perfiles de transición epidemiológica-nutricional. Por grupo, se calcularon medidas resumen de incidencia acumulada (IA), mortalidad y tasa de letalidad por COVID-19 (semana epidemiológica 50), estableciendo comparaciones mediante prueba t de Student. Se identificaron tres perfiles denominados: (1) reemergencia de enfermedades infecciosas, (2) persistencia de enfermedades cardiovasculares con mejoras sociosanitarias y en estilos de vida, y (3) consolidación de la tríada obesidad-sedentarismo-enfermedades cardiometabólicas. La IA y mortalidad por COVID-19 promedio fue mayor en provincias con perfil 1, en comparación con el perfil 2 (IA: p = 0,0159; mortalidad: p = 0,0187) y el perfil 3 (IA: p = 0,0205). La letalidad resultó mayor en el perfil 3, que aglomera provincias con situación socioeconómica más desfavorable, estimándose diferencias significativas respecto al perfil 2 (p = 0,0307). En conclusión, existen distintos perfiles epidemiológico-nutricionales en Argentina, que tienden a diferenciarse en su situación epidemiológica de COVID-19. Las estrategias contra COVID-19 deberían considerar las características epidemiológico-nutricionales y sociodemográficas de base.

Abstract: The study aimed to identify epidemiological-nutritional profiles in Argentina and to compare the burden of morbimortality from COVID-19. A multigroup ecological study was conducted with 24 geographic units in Argentina. We estimated the percent change from 2005 to 2018 in indicators of the epidemiological-nutritional transition and sociodemographic indicators according to geographic unit. We performed principal components analysis and hierarchical cluster analysis to identify geographic groupings to define profiles in the epidemiological-nutritional transition. By group, we calculated summary measures of COVID-19 cumulative incidence (CI), mortality, and case fatality (epidemiological week 50), establishing comparisons via Student's t test. Three profiles were identified: (1) reemergence of infectious diseases, (2) persistence of cardiovascular diseases despite social, health, and lifestyle improvements, and (3) consolidation of the triad obesity-sedentarism-cardiometabolic diseases. Mean COVID-19 cumulative incidence and mortality were higher in provinces with profile 1 compared to profile 2 (CI: p = 0.0159; mortality: p = 0.0187) and profile 3 (CI: p = 0.0205). Case-fatality was higher in profile 3, which includes provinces with more unfavorable socioeconomic conditions, showing significant differences from profile 2 (p=0.0307). In conclusion, there are distinct epidemiological-nutritional profiles in Argentina which tend to differ in terms of their COVID-19 epidemiological situation. Strategies to fight COVID-19 should consider the underlying epidemiological, nutritional, and sociodemographic characteristics.

[Emotions, concerns and reflections regarding the COVID-19 pandemic in Argentina]. / Emociones, preocupaciones y reflexiones frente a la pandemia del COVID-19 en Argentina.

The scope of this work is to explore the feelings and expectations that COVID-19 has generated in Argentina during the first stage of the pandemic. A survey of the World Health Organization adapted to the local context was applied. Open-ended questions were included to study people's feelings about COVID-19, and content analysis was subsequently conducted. In terms of results, it is revealed that the population surveyed feels uncertainty, fear and anguish, albeit a feeling of responsibility and care in the face of COVID-19 also emerges. Moreover, positive feelings regarding society stand out as an achievement of social interdependence. The results obtained show that the impact on mental health differs in accordance with gender, educational level, and perceived comfort in the home. The study concludes that the emotional and bonding dimensions of people are central to confronting the COVID-19 pandemic in Argentina. It is recommended that these dimensions, as well as their subjective and differential social impact among the different population groups, should be considered in the planning of policies to address the COVID-19 pandemic.

El objetivo de este trabajo es explorar los sentimientos y expectativas que genera el COVID-19 en Argentina durante la primera etapa de la pandemia. Se aplicó una encuesta de la Organización Mundial de la Salud adaptada al contexto local. Se incluyeron preguntas abiertas para indagar sentimientos de las personas frente al COVID-19, y se realizó un análisis de contenido. Como resultados se advierte que la población encuestada siente incertidumbre, miedo y angustia, pero también emerge un sentimiento de responsabilidad y cuidado frente al COVID-19. Así mismo se destacan sentimientos positivos para la sociedad como una valoración de la interdependencia social. Los resultados arribados señalan que el impacto en la salud mental es desigual según el género, el nivel educativo alcanzado y el confort percibido en el hogar. El estudio permite concluir que las dimensiones emocionales y vinculares de las personas resultan aspectos centrales ante la pandemia del COVID-19 en Argentina. Es recomendable que estas dimensiones, así como y su impacto subjetivo y social diferencial entre los diversos grupos poblacionales, sean consideradas en la planificación de políticas para afrontar el COVID-19.

Educational disparities in diabetes: a mediation analysis through BMI among urban adults from Argentina

INTRODUCTION: Low socio-economic status is linked to a higher probability of having type 2 diabetes mellitus in adulthood, including body mass index as a mediation factor in such association. However, the evidence from low- and middle-income countries is scarce and the mechanisms beyond this relationship are not yet completely acknowledge. OBJECTIVE: The purposes of this study are to i) evaluate the potential mediating role of body mass index in the relationship between educational background and diabetes mellitus; ii) assess whether these associations vary by gender and age. METHODS: Cross-sectional study. Data came from the Argentine National Health Survey of Risk Factors 2013 (n=30,119, 18-years-old and older). Age-adjusted genderspecific simple mediation modeling was conducted to estimate the potential mediation role of body mass index, in the association between educational level and self-reported diabetes mellitus. RESULTS: In women there was a positive direct (OR 1.11; 95% CI 1.09, 1.13) and indirect -through body mass indexassociations (OR 1.12; 95% CI 1.09, 1.36) between low education and diabetes mellitus. The associations were also significant for older women (50 years +), directly (OR 1.28; 95% CI 1.12, 1.44) and indirectly (OR 1.09; 95% CI 1.07, 1.13). In men, low education was associated with lower odds of diabetes mellitus (OR 0.86, 95% CI 0.76, 0.98). CONCLUSION: Decreasing body mass index might be an intermediate target to reduce the occurrence of diabetes mellitus among Argentinean adults, particularly among socially disadvantaged women

Nutrition transition profiles and obesity burden in Argentina.

OBJECTIVE: The present study aimed to identify nutrition transition (NT) profiles in Argentina (2005-2013) and assess their association with obesity in the adult population. DESIGN: A large cross-sectional study was performed considering data sets of nationally representative surveys. A multiple correspondence analysis coupled with hierarchical clustering was conducted to detect geographical clusters of association among sociodemographic and NT indicators. Multilevel logistic regression models were used to assess the effect of NT profile (proxy variable of contextual order) on obesity occurrence. SETTING: First, we used geographically aggregated data about the adult and child populations in Argentina. Second, we defined the population of adults who participated in the National Survey of Chronic Disease Risk Factors (2013) as the study population.ParticipantsTwenty-four geographical units that make up the territory of Argentina and 32 365 individuals over 18 years old living in towns of at least 5000 people. RESULTS: Three NT profiles were identified: 'Socionutritional lag' (characterized by undernutrition and socio-economically disadvantaged conditions; profile 1); 'Double burden of malnutrition' (undernutrition and overweight in highly urbanized scenarios; profile 2); and 'Incipient socionutritional improvement' (low prevalence of malnutrition and more favourable poverty indicator values; profile 3). Profiles 1 and 2 were significantly associated (OR; 95 % CI) with a higher risk of obesity occurrence in adults (1·17; 1·02, 1·32 and 1·44; 1·26, 1·64, respectively) compared with profile 3. CONCLUSIONS: Argentina is facing different NT processes, where sociodemographic factors play a major role in shaping diverse NT profiles. Most of the identified profiles were linked to obesity burden in adults.
