Calidad y diversidad de la dieta en la población urbana de Argentina

Una dieta variada se asocia a una mayor probabilidad de incorporar micronutrientes esenciales. El índice de diversidad de dieta (IDD) es el indicador que mide esta variedad, mientras que el índice de calidad de dieta (ICD) determina cuánto de esa diversidad refleja la inclusión de alimentos saludables. El objetivo del estudio fue evaluar la calidad y diversidad de la dieta de la población argentina identificando las diferencias por sexo, edad, nivel socioeconómico, estado nutricional y región. La muestra fue de 1266 sujetos de población urbana, de ambos sexos, entre 15 y 65 años y de todos los NSE. Se realizó una evaluación antropométrica y de la ingesta, a través de 2 recordatorios de 24 horas. El IDD se evaluó siguiendo las guías propuestas en el año 2016 por la Organización de las Naciones Unidas para la Alimentación y la Agricultura y el desarrollo del ICD se realizó siguiendo la metodología de Imamura y col. El ICD fue relativamente bajo, con un puntaje de 63.9%. El IDD fue de 4.48 de un máximo de 10, lo que refleja una dieta poca variada; adicionalmente, solo el 50% de la población informó una dieta variada. Estos indicadores fueron significativamente menores en las personas con bajo NSE. El IDD y el porcentaje de personas con dieta diversa fue mayor en los habitantes del área metropolitana de Buenos Aires. Este estudio evidenció que la calidad de la dieta en la población argentina es baja y con un consumo limitado de los grupos de alimentos que más aportan micronutrientesUCR::Vicerrectoría de Docencia::Salud::Facultad de Medicina::Escuela de MedicinaUCR::Vicerrectoría de Investigación::Unidades de Investigación::Ciencias Sociales::Instituto de Investigaciones Psicológicas (IIP)UCR::Vicerrectoría de Investigación::Unidades de Investigación::Ciencias de la Salud::Centro de Investigación en Neurociencias (CIN

Aspectos psicosociales, nutricionales, aptitud y actividad física en seis centros de jubilados de la Ciudad de Buenos Aires

INTRODUCCIÓN: El estado nutricional, la actividad física (AF) y las variables psicosociales plantean nuevos desafíos en los adultos mayores (AM). El objetivo fue explorar y describir aspectos psicosociales, nutricionales, aptitud y AF en AM que asisten a centros de jubilados de la Ciudad Autónoma de Buenos Aires (CABA). MÉTODOS: Se realizó un estudio exploratorio, observacional, transversal y cuantitativo con una muestra no probabilística de AM de ambos sexos, auto-válidos, en seis comunas de CABA durante 2017-2018. Se evaluó edad, sexo, índice de nivel socioeconómico (NSE), valoración sociofamiliar, cuestionario de reserva cognitiva e índice de bienestar de Pemberton, estado nutricional por Mini Nutritional Assessment, antropometría por índice de masa corporal, aptitud física por fuerza muscular y funcionalidad, gasto energético y nivel de AF por acelerometría. RESULTADOS: En una muestra de 150 AM de 74±7 años, el 90% (n=135) eran mujeres. El 48% pertenecía a un NSE bajo. Hubo presencia de riesgo social en el 50%, bienestar en el 97,6% y reserva cognitiva satisfactoria en el 53,6%. El 53,7% presentó sobrepeso/ obesidad con predominio en cuartil 1, y hubo 10,2% con riesgo o malnutrición. La debilidad muscular prevaleció en el tercer y cuarto cuartil. De los 57 AM que usaron acelerómetro, la mayoría tenía AF sedentaria y bajo gasto energético. DISCUSIÓN: La muestra explorada mostró riesgo/ problema social, exceso de peso y sedentarism

Co‐occurrence and clustering of sedentary behaviors, diet, sugar‐sweetened beverages, and alcohol intake among adolescents and adults: The latin american nutrition and health study (elans)

Poor diet, sedentary behaviors, sugar‐sweetened beverages (SSB) and alcohol intake seem to co‐exist in complex ways that are not well understood. The aim of this study was to provide an understanding of the extent to which unhealthy behaviors cluster in eight Latin America countries. A secondary aim was to identify socio‐demographic characteristics associated with these behaviors by country. Data from adolescents and adults from the “Latin American Health and Nutrition Study” was used and the prevalence of screen‐time, occupational and transportation–sedentary time, socializing with friends, poor diet, SSB and alcohol intake, alone and in combination, were identified. The eight Latin America (LA) countries added to analyses were: Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Peru, and Venezuela. Logistic regression was used to estimate associations between ≥2 behaviors clustering, socio‐demographics and weight status. Among 9218 individuals, the most prevalent behaviors were transportation and occupation–sedentary time, SSB and alcohol intake. Younger, female, married/living with a partner, low and middle‐income and obese individuals had higher chances for these clustering behaviors. These results provide a multi-country level of understanding of the extent to which behaviors co‐occur in the LA population.University of San FranciscoRevisión por pare

Association between built environment and physical activity in Latin American countries: a multicentre cross-sectional study

Abstract Objective: To assess the association between the physical activity level and the built environment by accessibility, microinfrastructure and security in Latin America (LA). Design: We conducted a multicentre cross-sectional study to collect physical activity and built environment data. The levels of physical activity were calculated through the International Physical Activity Questionnaire survey. Using the Neighbourhood Environment Walkability Scale-Abbreviated, characteristics of the built environment were measured through three domains: accessibility, microinfrastructure and security. To estimate the association of the built environment and physical activity, we used mixed effects logistic regression analysis. In addition, likelihood ratio test to account for clustered effect within countries and/or cities was used. Setting: Eight countries in LA. Participants: Adults aged 15-65 years (n=9218) living in urban areas and consented to participate of the Latin American Study of Nutrition and Health. Results: Most of the population in LA had access to a grocery store (97.2%), public transport stop (91.5%) and children's playground (81.6%). Metropolitan parks were more accessible in Ecuador (59.8%) and Colombia (59.2%) than in Venezuela (33.5%). Individuals located within 20 min of walking from sport facilities or children's playground areas were more likely to perform moderate-to-high physical activity OR 1.20 (95% CI 1.06 to 1.36) and OR 1.25 (95% CI 1.02 to 1.53), respectively. Only 14.5% of the population from the region considered that their neighbourhood had an adequate design for walking or cycling. Likewise, among adults living in LA, only 39.75% had the perception of living in a safe neighbourhood. Conclusions: This multicentre study shows that currently, LA built environment does not promote physical activity in the region. Our findings provide the rationale to push forward, at regional and national levels, policies and interventions that will help to achieve a safe, healthy and friendly built environment to encourage participation in active recreation and sports in leisure time.Coca Cola Company/[]//Estados UnidosHospital Infantil Sabará/[]//BrazilInternational Life Science Institute/[]/ILSI/ArgentinaUniversidad de Costa Rica/[]/UCR/Costa RicaPontificia Universidad Católica de Chile/[]//ChilePontificia Universidad Javeriana/[]//ColombiaUniversidad Central de Venezuela/[]/UCV/VenezuelaUniversidad San Francisco de Quito/[]//EcuadorInstituto de Investigación Nutricional de Perú/[]//PerúUCR::Vicerrectoría de Docencia::Salud::Facultad de Medicina::Escuela de Medicin

Energy imbalance gap, anthropometric measures, lifestyle, and sociodemographic correlates in Latin American adults. Results from the ELANS study

Overweight and obesity are often explained by an imbalance between energy intake and ex penditure. This, in addition to metabolic effects, makes it difficult to assess the real state of individual energy balance. This study aims to analyze the energy gaps between intake and expenditure in the adult population of Latin America, as well as its relationships with sociodemographic variables and nutrition status, to draw an epidemiological perspective based on the trends observed. The energy imbalance gap was used to this end. The difference between energy intake and expenditure can be applied as a reference to explain whether weight equilibrium can prevent weight gain. Moreover, the energy imbalance gap allows for a better understanding of the design of public health policies. Using data from the Latin American Study of Nutrition and Health, the energy imbalance gap in adult population from eight Latin-American countries was assessed in 5994 subjects aged from 19–65. Usual dietary intake was measured using two non-consecutive 24 h dietary recalls. The sociodemographic questionnaire was supplemented by anthropometric measurements. Physical activity was measured through the long International Physical Activity Questionnaire. Energy expenditure was obtained using the basal metabolic rate. For the overall sample, the mean energy intake was 1939.1 kcal (95% CI: 1926.9; 1951.3), the mean of energy expenditure was 1915.7 kcal (95% CI: 1906.4; 1924.9), and the mean of energy imbalance gap was 23.4 kcal (95% CI: 11.9; 35.0). Results show that energy intake and expenditure were higher in men. Moreover, subjects aged 19–34, of high socioeconomic level, who completed high school, were mestizos and were of normal weight consumed the highest number of calories. Overall, a positive energy imbalance gap was observed. Overweight and obese from Argentina, Costa Rica, Ecuador, Peru, and Venezuela showed a significantly lower energy imbalance gap than underweight subjects. These findings confirm the high variability of energy imbalance gap and the accompanying correlates of energy intake and expenditure. Further research is needed to specifically address interventions in low and middle-income countries such as many in Latin America, to help reduce the prevalence of obesity and eradicate undernutritionCoca Cola Company///Instituto Pensi/Hospital Infantil Sabara///BrasilInternational Life Science Institute of Argentina///ArgentinaUniversidad de Costa Rica//UCR/Costa RicaPontificia Universidad Catolica de Chile///ChilePontificia Universidad Javeriana///ColombiaUniversidad Central de Venezuela///VenezuelaUniversidad San Francisco de Quito///EcuadorInstituto de Investigación Nutricional from Perú///PerúUCR::Vicerrectoría de Docencia::Salud::Facultad de Medicina::Escuela de Medicin

We examined the relationship between socio-demographic correlates and HDI with physical activity and sedentary time in a cross-sectional study. Methods: We based our analyses on 2522 (53.1% women; 18-65 years [mean age 38.3 years]) adults drawn from the eight Latin America countries. Physical activity (light, moderate, vigorous, and moderate-to-vigorous intensity and steps) and sedentary time were assessed using Actigraph GT3X + accelerometers. Sex, age, and race/ethnicity were self-reported. The HDI country information was obtained from the United Nations Development Program. Results: For the age, ethnicity, vigorous physical activity and steps/day, there were significant differences between high and very high HDI countries. Women and younger age presented lower sedentary time than men and older. In moderate-to-vigorous physical activity, we found lower duration in women (-13.4 min/week), younger age (-0.1 min/week), and white/caucasian (-2.7 min/week) than men, older ages and mixed ethnicity. Women (-1266.5 steps/week) and very high HDI (-847.3 steps/week) presented lower steps than men and high HDI. Black (2853.9 steps/week), other (1785.4 steps/week), and white/caucasian ethnicity (660.6 steps/week) showed higher steps than mixed ethnicity. Conclusions: Different socio-demographic correlates are associated with physical activity intensity; however, HDI is associated with vigorous physical activity and steps in the Latin American region, which can in turn guide policies to promote physical activity in the region.info:eu-repo/semantics/publishedVersio

Intake of Vitamin E and C in Women of Reproductive Age: Results from the Latin American Study of Nutrition and Health (ELANS)

Vitamin E was identified as a lipophilic compound essential to maintain rat pregnancy. Low vitamin E intake during early pregnancy associates with congenital malformations and embryonic loss in animals and with miscarriage and intrauterine growth restriction in humans. Vitamin E protects cell membranes from lipoperoxidation and exerts non-antioxidant activities. Its function can be restored by vitamin C; thus, intake and circulating levels of both micronutrients are frequently analyzed together. Although substantial vitamin E inadequacy was reported worldwide, its consumption in Latin America (LatAm) is mostly unknown. Using data from the Latin American Study of Nutrition and Health (Estudio Latinoamericano de Nutrición y Salud, ELANS), we evaluated vitamin E and C intake in women of reproductive age (WRA) from eight LatAm countries and identified their main food sources. Two non-consecutive 24-h dietary recalls in 3704 women aged from 15 to 49 years and living in urban locations showed low average intake of vitamin E (7.9 mg/day vs. estimated average requirement (EAR) of 12 mg/day) and adequate overall vitamin C consumption (95.5 mg/day vs. EAR of 60 mg/day). The mean regional inadequacy was 89.6% for vitamin E and 36.3% for vitamin C. The primary food sources of vitamin E were fats and oils, as well as vegetables. Vitamin C intake was explained mainly by the consumption of fruit juices, fruits, and vegetables. Combined deficient intake of both vitamins was observed in 33.7% of LatAm women. Although the implications of low antioxidant vitamins' consumption in WRA are still unclear, the combined deficient intake of both vitamins observed in one-third of ELANS participants underscores the need for further research on this topic.Coca Cola Company///Estados UnidosHospital Infantil Sabará///BrazilInternational Life Science Institute//ILSI/ArgentinaUniversidad de Costa Rica//UCR/Costa RicaPontificia Universidad Católica de Chile///ChilePontificia Universidad Javeriana///ColombiaUniversidad Central de Venezuela//UCV/VenezuelaUniversidad San Francisco de Quito///EcuadorInstituto de Investigación Nutricional de Perú///PerúUCR::Vicerrectoría de Docencia::Salud::Facultad de Medicina::Escuela de Medicin

Is it possible to modify the obesogenic environment? - Brazil case

In recent decades, the prevalence of obesity has reached increasingly high rates among children and adolescents worldwide as the result of interactions between obesogenic environments and genetics. In Brazil, a middle-income country, the rates of overweight and obesity reached 18.9% and 8.7%, respectively, in 2015, corresponding to a prevalence of excess weight of 27.6%. Concomitant with these worrying data, the prevalence of insufficient physical activity in adolescents is 66.2% based on objective accelerometer measurements. The Brazilian government has taken concrete actions to contain the advance of obesity and physical inactivity and is taking part in political efforts combined with scientific evidence to develop laws, programs, and guidelines. While access to food outside the home, with the unstoppable intake of sweet beverages, sodium, and fat, is contributing to increased obesity, a lack of physical activity in leisure time or transportation must also be considered. However, while Brazil has been taking actions to address the obesogenic environment, with a view to reduce the prevalence and incidence of obesity and physical inactivity, more efforts are needed to implement these actions and approve measures that are still in progress.UCR::Vicerrectoría de Docencia::Salud::Facultad de Medicina::Escuela de Medicin

Association of moderate-to vigorous physical activity with neck circumference in eigth Latin American countries

Background: Physical activity is a cornerstone in the prevention and treatment of obesity. There are relatively few studies that explore the effect of accelerometer-determined moderate-to-vigorous physical activity (MVPA) on neck circumference (NC), most of them confined to single high-income countries. The present study investigated the association of accelerometer-determined MVPA with NC in adolescents and adults from eight Latin American countries, which are mostly upper-middle income countries. Methods: The sample consisted of 2370 participants (47.8% male) from the Latin American Study of Nutrition and Health, a multicenter cross-sectional nutrition and health surveillance study of a nationally representative sample from eight Latin American countries (Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Peru, and Venezuela). Times (min/day) in MVPA (defined as time accumulated at ≥1952 activity counts/min) was assessed by ActiGraph GT3X+ accelerometer over 7 days. NC for adolescent was categorized as abnormal if circumference was > 34.5 cm for boys and > 31.25 for girls, whereas for adults the cut-off points for abnormal were > 39 cm for men and > 35 cm women. Multilevel logistic models, including country and region as random effects and adjusted for sex, age, socioeconomic level, and educational level, were used to study the association between MVPA and NC. Results: The average time of MVPA was 34.88 min/day, ranging from 31.16 in Venezuela to 40.27 in Chile. Concerning NC, 37.0% of the sample was classified as having elevated NC. Chile was the country with the highest percentage of people with elevated NC (56.9%), and Colombia had the lowest percentage (24.8%). Overall, the MVPA (min/day) was associated with elevated NC (OR = 0.994, CI95% = 0.990-0.998). In Costa Rica and Peru, there were significant associations between MVPA and NC when analyzed by country. Conclusions: The present study provided evidence of significant associations between MVPA and NC in adolescents and adults from Latin America, independent of sex, age, socioeconomic level, and educational level. This analysis of accelerometry data and NC represents the first examination of these associations in eight Latin America countries. Further research is required to understand the differences between countries in the observed associations.Coca Cola CompanyUniversidad de Costa Rica///Costa RicaUniversidad San Francisco de Quito///EcuadorInstituto de Investigación Nutricional de Peru///PerúUniversidad Central de Venezuela///VenezuelaPontificia Universidad Católica de Chile///ChileInternational Life Science Institute of Argentina///ArgentinaPontificia Universidad Javeriana///ColombiaHospital Infantil Sabara///BrasilUCR::Vicerrectoría de Docencia::Salud::Facultad de Medicina::Escuela de Medicin
