Community-Based Prevention of Substance Use in Adolescents: Outcomes Before and During the COVID-19 Pandemic in Santiago, Chile.

A primary community prevention approach in Iceland was associated with strong reductions of substance use in adolescents. Two years into the implementation of this prevention model in Chile, the aim of this study was to assess changes in the prevalence of adolescent alcohol and cannabis use and to discuss the impact of the COVID-19 pandemic on the substance use outcomes. In 2018, six municipalities in Greater Santiago, Chile, implemented the Icelandic prevention model, including structured assessments of prevalence and risk factors of substance use in tenth grade high school students every 2 years. The survey allows municipalities and schools to work on prevention with prevalence data from their own community. The survey was modified from an on-site paper format in 2018 to an on-line digital format in a shortened version in 2020. Comparisons between the cross-sectional surveys in the years 2018 and 2020 were performed with multilevel logistic regressions. Totally, 7538 participants were surveyed in 2018 and 5528 in 2020, nested in 125 schools from the six municipalities. Lifetime alcohol use decreased from 79.8% in 2018 to 70.0% in 2020 (X2 = 139.3, p < 0.01), past-month alcohol use decreased from 45.5 to 33.4% (X2 = 171.2, p < 0.01), and lifetime cannabis use decrease from 27.9 to 18.8% (X2 = 127.4, p < 0.01). Several risk factors improved between 2018 and 2020: staying out of home after 10 p.m. (X2 = 105.6, p < 0.01), alcohol use in friends (X2 = 31.8, p < 0.01), drunkenness in friends (X2 = 251.4, p < 0.01), and cannabis use in friends (X2 = 217.7, p < 0.01). However, other factors deteriorated in 2020: perceived parenting (X2 = 63.8, p < 0.01), depression and anxiety symptoms (X2 = 23.5, p < 0.01), and low parental rejection of alcohol use (X2 = 24.9, p < 0.01). The interaction between alcohol use in friends and year was significant for lifetime alcohol use (ß = 0.29, p < 0.01) and past-month alcohol use (ß = 0.24, p < 0.01), and the interaction between depression and anxiety symptoms and year was significant for lifetime alcohol use (ß = 0.34, p < 0.01), past-month alcohol use (ß = 0.33, p < 0.01), and lifetime cannabis use (ß = 0.26, p = 0.016). The decrease of substance use prevalence in adolescents was attributable at least in part to a reduction of alcohol use in friends. This could be related to social distancing policies, curfews, and homeschooling during the pandemic in Chile that implied less physical interactions between adolescents. The increase of depression and anxiety symptoms may also be related to the COVID-19 pandemic. The factors rather attributable to the prevention intervention did not show substantial changes (i.e., sports activities, parenting, and extracurricular activities).

Facilitating Factors and Barriers to the Implementation of the Icelandic Prevention Model of Adolescent Substance Use in Chile: A Focus Group Study.

The use of alcohol and other drugs is a major public health problem in adolescence. The implementation of evidence-based prevention strategies is still scarce in the global south. This study aimed to evaluate facilitators and barriers to the implementation of the Icelandic prevention model of adolescent substance use (IPM) in Chile. We conducted a qualitative study of stakeholders during the implementation process of the IPM in six municipalities of the Metropolitan Region of Santiago, Chile. We convened six focus groups with parents and professionals from schools and municipal prevention teams (38 participants). Recordings were transcribed and submitted to a six-step thematic analysis. The following facilitators emerged: Participants valued the contribution of the IPM to articulate existing programs and teams, its community focus, and the local data obtained through the survey. There were also several barriers: Those included resistance to adopting a foreign model, the tension between generating local strategies and looking for measures to ensure the fidelity of the implementation, socioeconomic differences between and within municipalities, low-risk perception and supervision of parents in Chile, and a culture that generally does not discourage adolescent substance use. Implementation of the IPM was largely accepted by the stakeholders who agreed with the community approach of the model. The main barriers to consider were related to cultural and socioeconomic factors that need to be addressed in further research and may limit the effects of the model in Chile.

Parental practices and their association with alcohol and cannabis use among adolescents in Chile.

Background: Adolescent alcohol and cannabis use are common in Chile. The present study aimed to assess the relationship between perceived parenting practices and alcohol and cannabis use among adolescents in a Latin American context. Methods: We adapted and implemented a substance use prevention strategy in Chile, which included surveys of tenth-grade students from six municipalities in the Metropolitan Region of Greater Santiago. We assessed the reliability and factorial structure of the parenting scale with 16 items, which formed part of the survey. We dichotomized parenting scores into high (above the median) and low. The association of parenting practices with alcohol and cannabis use in adolescents was assessed using multivariate multilevel regression models. Results: A total of 7,538 tenth-grade students from 118 schools were included in the study. The 16-item scale of parenting practices showed good internal consistency (Omega total = 0.84), and three factors representing Relationship between parents and adolescents, Norms and monitoring, and Parents knowing their children's friends and the parents of their children's friends. High total scores of parenting were associated with lower odds of lifetime alcohol use (OR 0.57; 95% CI: 0.49-0.65), past-month alcohol use (OR 0.63; 95% CI: 0.57-0.70), lifetime drunkenness (OR 0.64; 95% CI: 0.58-0.72), and lifetime cannabis use (OR 0.54; 95% CI: 0.47-0.61). Above median scores on each parenting subscale were associated with significantly lower odds of substance use. The strongest associations were observed for the subscale Norms and monitoring. Interactions between parenting and gender showed a significantly stronger effect of parenting practices on alcohol and cannabis use among girls. Conclusion: Different types of parenting practices were associated with a lower prevalence of adolescent alcohol and cannabis use. Improving parenting practices has the potential to prevent adolescent substance use in Chile, especially among girls.

Brief Report: The Association of Adverse Childhood Experiences and Suicide-Related Behaviors Among 10th-Grade Secondary School Students.

The association between adverse childhood experiences and suicide-related behaviors (SRB) of adolescents has been widely studied in Western high-income countries, but not yet in Latin America. The aim of this study was to determine this association and to explore a dose-response relationship between adverse childhood experiences and SRB in Chile. We conducted a cross-sectional survey to assess adverse childhood experiences up to 1 year prior to the survey and SRB (suicide ideation and attempts) in a sample of secondary school students. Multilevel and multivariable logistic regressions were run with SRB as dependent and adverse childhood experiences as independent variables, adjusted by self-esteem, general mental health, friend and parental support, and the age at onset of cannabis and alcohol use. We included 7,458 adolescents (48.7% girls), mean age = 16.0 (SD = 0.7), and found a prevalence of 78.1% for at least one adverse childhood experience. The 6-month prevalence of suicidal ideation was 18.1% (95% confidence interval [CI]: 17.2%-19.0%), and the prevalence of suicide attempts was 5.0% (95% CI: 4.6-5.6). Among all adverse childhood experiences, only sexual abuse was a risk factor for both SRB. We also found an independent effect of the total number of adverse childhood experiences on suicidal ideation (p < .001) and on suicide attempts (p < .001). Additionally, ages at onset of alcohol and cannabis use were associated with suicidal ideation and suicidal attempts, respectively. This is the first study exploring the influence of adverse childhood experiences on suicide-related behaviors in adolescents from Latin America.HIGHLIGHTSSexual abuse is associated with suicidal ideation and suicide attempts in 10th-grade secondary school studentsThere is a dose-response effect between adverse childhood experiences and suicide-related behaviorAges at onset of alcohol and cannabis use were associated with suicidal ideation and suicidal attempts, respectively.

The alcohol prevention magnitude measure: Application of a Spanish-language version in Santiago, Chile.

BACKGROUND: The Alcohol Prevention Magnitude Measure (APMM) is an instrument to monitor and improve substance use prevention at the community level developed in Sweden. The aim of this study was to produce and apply a Spanish-language version of the APMM. METHOD: We translated and adapted the APMM using an expert panel. We retained 37 indicators in five dimensions, with total scores ranging from 0 to 100 points and 0 to 20 in each dimension. The instrument was administered to the prevention coordinators in six socioeconomically heterogeneous municipalities of Santiago de Chile, during the pilot implementation of a community-based prevention model in 2019 and 2020. We calculated median scores for the instrument and each dimension. We tested for differences between 2019 and 2020 using the Wilcoxon Test and between municipalities with the Friedman Test. RESULTS: The Spanish version of the APMM was acceptable to stakeholders. The median scores were 49.3 (range: 34.0 to 64.0) in 2019 and 67.3 (range 55.5 to 80.5) in 2020. The median scores for Staff and budget were 14.0 in 2019 and 2020, for Prevention policy 5.0 in 2019 and 16.0 in 2020, for Cooperation with key agents 12.0 in both years, for Supervision and alcohol licenses 4.3 in 2019 and 9.0 in 2020, and for Prevention activities 11.0 in 2019 and 15.0 in 2020. The scores in the dimensions Prevention policy and Supervision and alcohol licenses significantly increased in 2020. The differences between the municipalities were not significant. CONCLUSIONS: Improvements of the prevention index between 2019 and 2020 in the dimension Prevention policies may be related to the intervention. Improvements in Supervision and alcohol licenses could be related to curfew policies in the context of the COVID-19 pandemic. The Spanish version of the APMM deserves larger scale testing in Latin America.

Dietary Patterns in the Argentinian Population and Their Association With Sociodemographic Characteristics: Results From the ELANS Study (2014-2015).

Aim: To describe dietary patterns in the Argentinian population and their association with sociodemographic characteristics. Methods: Cross-sectional analysis of Argentina's food consumption and sociodemographic data of 1,266 men and women between 15 and 65 years from the Latin American Study of Nutrition and Health carried out between March 2014 and December 2015. Dietary patterns were identified by using factor analysis and median factor scores were calculated for gender, age, region, body mass index (BMI), socioeconomic, education, and physical activity categories. Results: Five dietary patterns were identified. Western, Local Western, and Rural were generally characterized by high consumptions of animal fats, sugar-sweetened beverages, meats or processed meats, pizza and empanadas, sweets, pastries, and low consumption of fruits and vegetables. Traditional pattern was mainly characterized by consumption of oils, starchy vegetables, and red meat and Sweet Prudent by milk and yogurt, vegetables, fruit, artificially sweetened beverages, sweets, and cookies. Higher adherence to the Sweet Prudent pattern was observed in women, in people who meet physical activity guidelines and higher socioeconomic and educational levels. Higher adherence to traditional pattern was only observed for men. Higher adherence to the rest of the patterns was observed mostly by men, young, leaner, lower socioeconomic, and educational levels, not meeting physical activity guidelines, from the metropolitan area of Buenos Aires or northern regions. Conclusion: Food consumption in Argentina is expressed in a diversity of dietary patterns. Men, younger, and sedentary individuals, with lower socioeconomic and educational level, from the metropolitan area of Buenos Aires and northern regions, seem to have higher adherence to least healthy dietary patterns.

[Diet quality and diversity in the urban population of Argentina]. / Calidad y diversidad de la dieta en la población urbana de Argentina.

Following a varied diet is associated with a healthier diet and a greater likelihood of incorporating the necessary micronutrients. The dietary diversity index (DDI) is the indicator that measures this variety, while the diet quality index (DQI) determines how much of this diversity consists of the inclusion of healthy foods. The aim of the study was to evaluate the quality and diversity of the diet of the Argentine population by identifying differences by sex, age, socioeconomic level, nutritional status and region. The sample consisted of 1266 subjects of urban population, of both sexes, between 15 and 65 years of age and of all socioeconomic levels. Anthropometric and intake assessment was performed, through 2 24-hour recalls. The DDI was assessed following the guidelines proposed in 2016 by Food and Agriculture Organization and the development of the DQI was performed following the methodology of Imamura y col. The DQI was relatively low, with a score of 63.9%. The DDI was 4.48 out of a maximum of 10, reflecting a poorly varied diet; additionally, only 50% of the population reported a varied diet. These indicators are significantly lower in people with low SEL. The DDI and the percentage of people with a diverse diet was higher in people from the metropolitan area of Buenos Aires. This study showed that the quality of the diet in the Argentine population is low and with a limited consumption of the food groups that provide the most micronutrients.

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 micronutrientes.

A Comparison of Associations Between Self-Reported and Device-Based Sedentary Behavior and Obesity Markers in Adults: A Multi-National Cross-Sectional Study.

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.

Breakfast in Latin America: Evaluation of Nutrient and Food Group Intake Toward a Nutrient-Based Recommendation.

BACKGROUND: Little is known about breakfast habits of the Latin American (LA) population to support nutritional recommendations for a balanced breakfast in this region. OBJECTIVE: To evaluate the nutritional composition of breakfast in the LA population and to propose recommendations for a balanced breakfast. DESIGN: This multicenter cross-sectional study evaluated food and nutrient intake of nationally representative samples of urban populations of 8 LA countries (Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Peru, and Venezuela) in 2014-2015. PARTICIPANTS/SETTING: The sample comprised 8714 participants from the Latin American Study of Nutrition and Health, aged 15 to 65 years, randomly recruited according to geographical location, sex, age, and socioeconomic level. MAIN OUTCOME MEASURES: Two 24-hour recalls were used to examine dietary intake. Breakfast consumers were stratified by tertiles of Nutrient-Rich Foods Index 9.3 (NRF9.3) to assess the overall diet quality of individuals. Nutrient intake at breakfast of those in the upper tertile of NRF9.3 pooled for the 8 countries was used as a reference for the development of recommendations for LA adolescents and adults. STATISTICAL ANALYSES: Comparison of food and nutrient intake of breakfast across NRF9.3 tertiles were analyzed using the Kruskal-Wallis rank sum test. RESULTS: Overall breakfast was an important contributor to protein, carbohydrate, and B vitamin intakes but also to added sugar and total and saturated fat intakes relative to daily intakes. Individuals in the upper NRF9.3 tertile had higher intake of key micronutrients such as calcium and potassium at breakfast compared with other tertiles. White breads/rolls/tortillas were the most consumed food group (60%), followed by butter/margarine (40%) and coffee/tea without milk (34%-50%). CONCLUSIONS: Breakfast contributed to the daily intake of B vitamins, protein, and carbohydrates but also added sugar and total and saturated fat intakes for all countries. The proposed recommendations support the nutrient density of existing highest-quality breakfast in the LA population while addressing concerns about nutrients to be encouraged or reduced.

Alcohol Contribution to Total Energy Intake and Its Association with Nutritional Status and Diet Quality in Eight Latina American Countries.

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.

Inadecuación de micronutrientes en adolescentes y adultos argentinos de población urbana. Resultados de estudio latinoamericano de nutrición y salud (ELANS) / Inadequancy of micronutrients in argentine adolescents and adults from the urban population. Results of the Latin Amercan study of nutritio and health (ELANS)

Introducción: conocer la deficiencia de micronutrientes en la ingesta es imprescindible para desarrollar estrategias de intervención y para evaluar programas destinados a mejorar el estado nutricional. Objetivos: determinar el consumo y la inadecuación de la ingesta de hierro, calcio, zinc, ácido fólico y vitaminas A, B12, C,D y E en la dieta de la población argentina. Materiales y métodos: la muestra fue de 1.266 individuos (población urbana 15-65 años), estratificada por región, edad, sexo y nivel socioeconómico (NSE). Los datos de ingesta fueron recolectados con dos recordatorios de 24 horas (R24). Resultados: el riesgo relativo (RR) de inadecuación de ingesta de calcio, ácido fólico y vitamina B12 fue mayor para las mujeres. El consumo y la inadecuación de hierro mostraron diferencias significativas por sexo (0,3% hombres, 11% mujeres). La inadecuación de vitamina D fue casi del 100% para toda la muestra. Todos los grupos etarios presentaron alta inadecuación de calcio y vitaminas C, A y D. Adolescentes, adultos mayores de 50 años y población de NSE bajo presentaron mayor RR de inadecuación de calcio (1,18; 1,21 y 1,17 respectivamente). Se observó una disminución significativa de la media de consumo de calcio (mg) (856,4; 770,5; 745,3), vitaminas A (mcg) (643,6; 601,8; 536,2), C (mg) (54,2; 52,3; 44,8) y D (mcg) (3,7; 3,7; 3,2) al disminuir el NSE. La inadecuación en calcio aumentó significativamente con el índice de masa corporal. Conclusiones: mejorar la ingesta de micronutrientes a través de políticas públicas sobre educación alimentaria y desarrollo científico es una prioridad de salud pública

Introduction: knowing the deficiency of micronutrients intake is essential to develop intervention strategies and to evaluate programs aimed at improving nutritional status. Objectives: to determine the consumption and inadequacy of the intake of iron, calcium, zinc, folic acid and vitamins A, B12, C, D and E, in the diet of the Argentine population. Materials and methods: the sample consisted of 1,266 individuals (urban population 15-65 years old), stratified by region, age, sex and socioeconomic level (SEL). Intake data was collected with two 24-hour reminders (R24). Results: the relative risk (RR) of inadequate intake of calcium, folic acid, and vitamin B12 was higher for women. Iron consumption and inadequacy showed significant differences by sex (0.3% men, 11% women). Vitamin D inadequacy was almost 100% for the entire sample. All age groups presented high prevalence of inadequacy in calcium and vitamins C, A and D. Adolescents, adults over 50 years and the low SEL population presented a higher RR of calcium inadequacy (1.18, 1.21 and 1.17, respectively). A significant decrease in the average consumption of calcium (mg) (856.4, 770.5, 745.3), vitamins A (mcg) (643.6, 601.8, 536.2), C (mg) (54.2, 52.3, 44.8) and D (mcg) (3.7, 3.7, 3.2) was observed as the SEL decreased. Calcium inadequacy increased significantly with the body mass index. Conclusions: improving the intake of deficient micronutrients through public policies based on food education and scientific development is a public health priority

Technology-Assisted Collaborative Care Program for People with Diabetes and/or High Blood Pressure Attending Primary Health Care: A Feasibility Study.

The comorbidity of depression with physical chronic diseases is usually not considered in clinical guidelines. This study evaluated the feasibility of a technology-assisted collaborative care (TCC) program for depression in people with diabetes and/or high blood pressure (DM/HBP) attending a primary health care (PHC) facility in Santiago, Chile. Twenty people diagnosed with DM/HBP having a Patient Health Questionnaire-9 score ≥ 15 points were recruited. The TCC program consisted of a face-to-face, computer-assisted psychosocial intervention (CPI, five biweekly sessions), telephone monitoring (TM), and a mobile phone application for behavioral activation (CONEMO). Assessments of depressive symptoms and other health-related outcomes were made. Thirteen patients completed the CAPI, 12 received TM, and none tried CONEMO. The TCC program was potentially efficacious in treating depression, with two-thirds of participants achieving response to depression treatment 12 weeks after baseline. Decreases were observed in depressive symptoms and healthcare visits and increases in mental health-related quality of life and adherence to treatment. Patients perceived the CPI as acceptable. The TCC program was partially feasible and potentially efficacious for managing depression in people with DM/HBP. These data are valuable inputs for a future randomized clinical trial.

Understanding the Relationship between Depression and Chronic Diseases Such as Diabetes and Hypertension: A Grounded Theory Study.

There is a bi-directional relationship between depression and chronic illnesses such as diabetes and hypertension. This comorbidity is associated with higher mortality risk and diminishes the efficacy of interventions. The specific mechanisms of this mutual influence are still not fully understood, and most intervention protocols address these conditions separately. This study aims to improve our understanding of this relationship. We interviewed 18 patients and 24 health care professionals, focusing on understanding the different ways in which depression and chronic illness could influence each other. Our results show a common cyclical pattern and specific situations where the reported bi-directional relationship does not occur. We discuss the importance of opening a space for the patient's grief process after the chronic illness diagnosis, managing the demands and stress of the patient's treatment, and how to adjust the treatment to the different needs and possibilities of each person.

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

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. TRIAL REGISTRATION NUMBER: NCT02226627.

Principales alimentos con azúcares añadidos y su variación geográfica y sociodemográfica: estudio latinoamericano de nutrición y salud (ELANS) / Main foods with added sugars and their geographic and sociodemographic variation: Latin American study of nutrition and health (ELANS)

Diversos estudios epidemiológicos y de intervención apuntan a una asociación fuerte y consistente entre la ingesta excesiva de azúcares y el riesgo de desarrollar caries dentales y enfermedades crónicas no transmisibles. El objetivo fue describir los 10 principales alimentos que contribuyen a la ingesta de azúcares añadidos en muestras representativas de poblaciones urbanas de ocho países latinoamericanos, y considerar diferencias por país, sexo, nivel socioeconómico (NSE) y grupo de edad. Se realizó una encuesta transversal multinacional en hogares de Argentina, Brasil, Chile, Colombia, Costa Rica, Ecuador, Perú y Venezuela (N=9218; 15­65 años). La contribución porcentual a la ingesta total del nutriente sirvió para identificar los alimentos aportadores. Los datos se estratificaron por país, sexo, NSE y grupo de edad y se compararon los gramos por día. Excepto en Perú y en el grupo de 50 a 65 años, los refrescos figuraron como el principal contribuyente a la ingesta de azúcares añadidos. Las bebidas caseras y las industrializadas también destacaron. Argentina fue el país con mayor ingesta de azúcares añadidos aportados por bebidas industrializadas, y Chile el país con menor frecuencia de bebidas como fuentes. Entre los 10 contribuyentes, la ingesta de azúcares añadidos fue mayor en el sexo masculino, excepto para sacarosa y pasteles dulces. Mayores ingestas de azúcares provenientes del jugo de fruta natural y sacarosa fueron observadas en el NSE más bajo. Las mayores y menores ingestas en los grupos de edad cambian de acuerdo con la fuente alimentaria. En conclusión, las bebidas azucaradas fueron los principales contribuyentes a la ingesta de azúcares añadidos, y la ingesta varió según la ubicación geográfica y los factores sociodemográficos(AU)

This study aimed to describe the top 10 foods that contribute to added sugars intake in representative samples of urban populations in eight Latin American countries, and consider differences by country, sex, socioeconomic level (SEL), and age group. A household-based, multinational, cross-sectional survey was conducted in Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Peru, and Venezuela (N=9218; 15­65 years). Contributors to added sugars were identified and listed based on the percentage of contribution to total intake of this nutrient. Data were stratified by country, sex, SEL, and age group, and the grams per day compared. Except in Peru and in the 50 to 65 years age group, soft drinks were the leading contributor to added sugar intake. Homemade beverages together industrialized beverages have been a prominent position on ranking. In general, the highest intake of added sugars by industrialized beverages was from Argentina, and the lowest frequency of beverages as sources of added sugars was observed in Chile. Among the top 10 contributors, male sex had highest added sugar intake, except for sucrose and sweet cakes. Higher intakes of sugars from natural fruit juice and sucrose were observed in the lower SEL. The highest and lowest intakes in the age groups change according to the food source. In conclusion, sugar-sweetened beverages were main contributors to added sugar intake, and the intake vary with geographical location and sociodemographic factors(AU)

Socioeconomic Status Impact on Diet Quality and Body Mass Index in Eight Latin American Countries: ELANS Study Results.

Poor health and diet quality are associated with living within a low socioeconomic status (SES). This study aimed to investigate the impact of SES on diet quality and body mass index in Latin America. Data from the "Latin American Health and Nutrition Study (ELANS)", a multi-country, population-based study of 9218 participants, were used. Dietary intake was collected through two 24 h recalls from participants of Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Peru and Venezuela. Diet quality was assessed using the dietary quality score (DQS), the dietary diversity score (DDS) and the nutrients adequacy ratio (NAR). Chi-squared and multivariate-variance analyses were used to estimate possible associations. We found that participants from the low SES consumed less fruits, vegetables, whole grains, fiber and fish and seafood and more legumes than those in the high SES. Also, the diet quality level, assessed by DQS, DDS and NAR mean, increased with SES. Women in the low SES also showed a larger prevalence of abdominal obesity and excess weight than those in the middle and high SES. Health policies and behavioral-change strategies should be addressed to reduce the impact of socioeconomic factors on diet quality and body weight, with gender as an additional level of vulnerability.

A collaborative, computer-assisted, psycho-educational intervention for depressed patients with chronic disease at primary care: protocol for a cluster randomized controlled trial.

BACKGROUND: Depression and chronic diseases are frequently comorbid public health problems. However, clinical guidelines often fail to consider comorbidities. This study protocol describes a cluster randomized trial (CRT) aimed to compare the effectiveness of a collaborative, computer-assisted, psycho-educational intervention versus enhanced usual care (EUC) in the treatment of depressed patients with hypertension and/or diabetes in primary care clinics (PCC) in Santiago, Chile. METHODS: Two-arm, single-blind, CRT carried out at two municipalities in Santiago, Chile. Eight PCC will be randomly assigned (1:1 ratio within each municipality, 4 PCC in each municipality) to the INTERVENTION or EUC. A total of 360 depressed patients, aged at least 18 years, with Patient Health Questionnaire-9 Item [PHQ-9] scores ≥15, and enrolled in the Cardiovascular Health Program at the participating PCC. Patients with alcohol/substance abuse; current treatment for depression, bipolar disorder, or psychosis; illiteracy; severe impairment; and resident in long-term care facilities, will be excluded. Patients in both arms will be invited to use the Web page of the project, which includes basic health education information. Patients in the INTERVENTION will receive eight sessions of a computer-assisted, psycho-educational intervention delivered by trained therapists, a structured telephone calls to monitor progress, and usual medical care for chronic diseases. Therapists will receive biweekly and monthly supervision by psychologist and psychiatrist, respectively. A monthly meeting will be held between the PCC team and a member of the research team to ensure continuity of care. Patients in EUC will receive depression treatment according to clinical guidelines and usual medical care for chronic diseases. Outcome assessments will be conducted at 3, 6, and 12 months after enrollment. The primary outcome will be depression improvement at 6 months, defined as ≥50% reduction in baseline PHQ-9 scores. Intention-to-treat analyses will be performed. DISCUSSION: This study will be one of the first to provide evidence for the effectiveness of a collaborative, computer-assisted, psycho-educational intervention for depressed patients with chronic disease at primary care in a Latin American country.

Accelerometer-Measured Daily Step Counts and Adiposity Indicators among Latin American Adults: A Multi-Country Study.

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 (ß: -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.

Aspectos psicosociales, nutricionales, aptitud y actividad física en seis centros de jubilados de la Ciudad de Buenos Aires / Psychosocial and nutritional aspects, physical fitness and activity in six retirement centers of Buenos Aires City

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 sedentarismo

Agreement Between Self-Reported and Device-Based Sedentary Time among Eight Countries: Findings from the ELANS.

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.
