Ethnic Disparities in Nutritional Status among Older Adults: Evidence from the Survey of Health, Welfare and Aging (SABE) Ecuador.

This study aims to identify those populations that should be targeted by specific interventions. A cross-sectional design was utilized. Ordered logistic regression analysis was utilized to assess the association between ethnic identity and risk of malnutrition. Data were drawn from Ecuador's Survey of Health, Welfare and Aging (SABE). The final sample consisted of 4,572 people who were 60 years or older who were able to provide responses to the survey by themselves. Ethnic identity was categorized into four: indigenous, mestizo (Spanish and Indigenous mixed heritage), Afro-Ecuadorian/mulato, and other. Risk of malnutrition was measured using Mini Nutritional Assessment Short-Form (MNA-SF). A range of covariates were selected from three groups of factors: sociodemographic, health-related, and social network. Results revealed that the indigenous ethnicity was the only group who had significantly higher risk of malnutrition compared to mestizo even after controlling for a range of covariates including socio-economic status, health related factors, and social support. Findings suggest the existence of underlaying factors hindering the risk of malnutrition among indigenous older adults. Considering the information revealed by SABE, interventions and other strategies should be targeted and designed specifically accounting for the needs, preferences, and culture of the most vulnerable population.

Malnutrition inequalities in Ecuador: differences by wealth, education level and ethnicity.

OBJECTIVE: To describe and quantify the magnitude and distribution of stunting, wasting, anaemia, overweight and obesity by wealth, level of education and ethnicity in Ecuador. DESIGN: We used nationally representative data from the 2012 Ecuadorian National Health and Nutrition Survey. We used the Multidimensional Poverty Index (MPI) as a proxy of wealth. The MPI identifies deprivations across three dimensions (health, education and standard of living). We defined education by years of schooling and ethnicity as a social construct, based on shared social, cultural and historical experiences, using Ecuadorian census categories. SETTING: Urban and rural Ecuador, including the Amazon rainforest and the Galapagos Islands. PARTICIPANTS: Children aged <5 years (n 8580), adolescent women aged 11-19 years (n 4043) and adult women aged 20-49 years (n 15 203). RESULTS: Among children <5 years, stunting and anaemia disproportionately affected low-wealth, low-education and indigenous groups. Among adolescent and adult women, higher rates of stunting, overweight and obesity were observed in the low-education and low-wealth groups. Stunting and short stature rates were higher in indigenous women, whereas overweight and obesity rates were higher in Afro-Ecuadorian women. CONCLUSIONS: Malnutrition differs significantly across sociodemographic groups, disproportionately affecting those in the low wealth tertile and ethnic minorities. Rates of stunting remain high compared with other countries in the region with similar economic development. The effective implementation of double-duty actions with the potential to impact both sides of the double burden is urgently required.

Use, knowledge, and effectiveness of nutritional traffic light label in an urban population from Ecuador: a pilot study.

BACKGROUND: The nutritional traffic light label (NTLL) has become one of the most used Front of Package labels (FOP's) around the world, for its simple and easy to understand graphical system. In Ecuador, this labelling system has recently been implemented; then, this research aims to evaluate the use and knowledge of NTLL and its effectiveness as a public health promotion strategy. METHOD: In a cross-sectional study at two different urban supermarkets in Quito-Ecuador, a survey was conducted in 73 participants to inquire about knowledge, perspectives and purchasing habits regarding the NTLL. Objective data obtained from pictures of the participants'purchase was compared with subjective data obtained from the survey. For categorical variables, Chi square or Fisher's Exact test were used and variables with a statistical significance at α = 0.1 were included in multivariate logistic regression models. RESULTS: 88.7% of participants knew about the NTTL. 27.4% reported using the NTLL, while 28.4% of participants were observed to really use it. Significant associations between self-knowledge of the NTLL and education level (p = 0.007) or knowledge level (p = 0.001) were found. A significant association was also found between the refered use of the NTLL and the shopping influencing factor (p = 0.02). In the multivariate analysis an association between knowledge of the NTLL and observed use was found only when adjusted for the supermarket (p = 0.038). CONCLUSION: This study found that the level of knowledge of the NTLL in the studied population was relatively high; however, both the referred and the observed use of the NTLL were low. Use and knowledge of the NTLL were associated with the socioeconomic and educational status of the participants. Thus, the change in nutritional patterns needs additional strategies to put the NTLL before the brand once customers make their purchases.

Overweight, obesity, and food consumption in Galapagos, Ecuador: a window on the world.

BACKGROUND: In order to understand why rates of overweight and obesity are so high in the Ecuadorian province of Galapagos, this study analyzes changes in household food expenditures and perceptions and practices related to food consumption patterns. Galapagos is understood as an unusual but not unique case because conditions there graphically illustrate trends observed in communities and countries worldwide. A mixed methods approach was employed: a quantitative component was based on expenditures for foods classified according to the NOVA system, and a qualitative component utilized focus group discussions, key informant interviews, and structured observations. RESULTS: Galapagos residents increased consumption of processed and ultra-processed foods and decreased consumption of unprocessed and minimally processed foods. Perceived barriers to healthy diets include price, availability, and quality of fresh produce, as well as easy access to industrialized processed and ultra-processed foods. CONCLUSIONS: Changes in consumption patterns represent both local conditions and global trends; in that sense, the factors that affect Galapagos residents are not unique. Hence, these findings help elucidate processes observed in communities around the world.

The double burden of chronic malnutrition and overweight and obesity in Ecuadorian mothers and children, 1986-2012.

BACKGROUND:: The simultaneous presence of undernutrition and over-nutrition represents a paradox in global public health and is of increasing concern in Ecuador, where chronic malnutrition and overweight and obesity occur in the context of demographic and epidemiologic transitions. Two overlapping trends are present in Ecuador; while levels of stunting have decreased slowly in the past three decades, increasing proportions of children <5 years and women of reproductive age suffer from overweight and obesity. AIM:: To analyze stunting and overweight and obesity in children <5 and their mothers aged from 15 to 49 years in the context of demographic and household characteristics between 1986 and 2012. METHODS:: This study compares data from nationally-representative surveys conducted in Ecuador in 1986, 2004, and 2012, each of which collected information on children <5 and mothers aged 15-49 years. RESULTS:: The prevalence of chronic malnutrition in children <5 decreased at different rates among Ecuadorians who differ in terms of residence, socioeconomic status, and mothers' level of education, while overweight and obesity increased dramatically in the same period. CONCLUSION:: Chronic malnutrition in children <5 and overweight in children <5 and mothers 15-49 years represent a double burden of malnutrition in Ecuador. The phenomena differ in their effects, and, while the prevalence of stunting is declining in Ecuador as it is in many parts of the world, the problem of overweight and obesity has emerged in dramatic fashion, and currently represents an extraordinary challenge to public health.

A qualitative study of consumer perceptions and use of traffic light food labelling in Ecuador.

OBJECTIVE: To analyse patterns of knowledge, comprehension, attitudes and practices regarding the traffic light label placed on processed food packages to inform Ecuadorian consumers about levels of added fat, sugar and salt. DESIGN: Twenty-one focus group discussions organized by age group, sex and place of residence. Interviews with representatives of companies that manufacture or market processed foods. Analysis of regulations and structured observations of processed food labels. SETTING: Cities and towns in Ecuador's coastal, highland and eastern lowland regions. SUBJECTS: One hundred and seventy-eight participants in twenty-one focus group discussions and nine key informants. RESULTS: Focus group participants knew about the traffic light label and understood the information it conveys, but not all changed their attitudes and practices related to the purchase and consumption of processed foods. Children, adolescents and adult males reported using the information infrequently; adolescents interested in health and adult women used the label the most to select products. Representatives of companies that manufacture or market processed foods generally opposed the policy, stating that the information is misleading. Nevertheless, some companies have reduced levels of added fat, sugar or salt in their products. CONCLUSIONS: The traffic light label is an effective tool for conveying complex information. Its potential contribution to reduce consumption of products with high levels of fat, sugar and salt could be enhanced by promoting healthy diets among consumers who have not changed purchasing and consumption behaviour, by placing the label on front panels and by monitoring the production and marketing of processed foods.

Breastfeeding practices and complementary feeding in Ecuador: implications for localized policy applications and promotion of breastfeeding: a pooled analysis.

BACKGROUND: Best practices in breastfeeding are often not followed despite appropriate levels of knowledge and positive attitudes regarding the benefits of human milk. For many reasons, some women do not initiate breastfeeding, suspend breastfeeding early, or initiate complementary feeding earlier than recommended. Usual measurement methods use large sample surveys at a national scale, which are not well suited for monitoring sub-national differences. METHODS: In order to understand how local infant feeding practices could influence policy and promotion practices, we apply data pooling methodology to analyse breastfeeding patterns in different Ecuadorian settings: Cumbayá parish, located near Quito, the Ecuadorian capital; the city of Macas and rural surroundings in the Amazon basin province of Morona Santiago; and the province of Galapagos. Surveys were conducted independently between August 2017 and August 2018; while they are representative of each respective setting, sampling designs and survey methods differ, but the same demographic information and data based on standard breastfeeding indicators established by the World Health Organization (WHO) were collected. In order to account for differences in the different settings, the design effect of each survey was considered in the analysis. RESULTS: Significant differences were found in breastfeeding practices between the suburban Cumbayá parish near Quito and Galapagos on one hand, and urban and rural parts of Morona Santiago, on the other. The rates of early breastfeeding initiation and age-appropriate breastfeeding are significantly higher in urban and rural Morona Santiago then in Cumbayá or Galapagos, while the rate of exclusive breastfeeding is highest in rural parts of Morona Santiago. No significant differences were found in complementary feeding practices between Cumbayá and Galapagos, but there are with urban and rural Morona Santiago. Initiation of breastfeeding in the first hour after birth occurs in only 36.2% of cases in Cumbayá but in 75.4% of cases in urban Morona. CONCLUSIONS: Differences among regions reflect specific opportunities and barriers to practices related to promoting optimal infant health and nutrition. Consequently, regional or local conditions that often are not apparent in national-level data should orient policies and promotion activities in specific populations.

Unhealthy food consumption among Ecuadorian children: A cross-sectional study in the context of the school food regulation / Consumo de alimentos poco saludables en niños ecuatorianos: estudio transversal en el contexto del reglamento de alimentación escolar

Introduction. The intake of energy-dense unhealthy food at school could influence the overall energy intake of children. Objective: To characterize the patterns of buying a snack at school and to analyze the association of these patterns with the source of the school snack (brought from home or bought at school) and screen time. Materials and methods: A cross-sectional study was conducted from October 2018 until May 2019 among school children (9 to 12-year-olds) from Cuenca-Ecuador. Intake of energy-dense unhealthy food groups, the source of the school snack, and screen time were assessed using questionnaires. Multiple correspondence analysis was used to identify intake patterns of unhealthy food groups, and logistic regression to assess the association between intake of energy-dense unhealthy food groups (FG) with the school snack source. Results: Among 1,028 children recruited 63%, 42%, 30% and 22% of the children reported consuming sweets/confiture, savory snacks, fast food, and pastry products, respectively, at least two days per week. Around 39% of the children were classified as "Frequent consumers of energy-dense unhealthy FG". Buying the snack at school was associated with a more frequent intake of sweets/confiture (OR=1.56, CI 95% =1.05-2.32) and fast food (OR=2.01, CI 95% =1.15-3.50) during the week, as well as with being classified in the "frequent consumer of energy-dense unhealthy FG" (OR=1.99, 95% CI=1.40-2.82). Conclusions: Ecuadorian children still consume prohibited unhealthy foods at school. These results reinforce the importance of evaluating, monitoring, and adapting strategies to promote a balanced diet(AU)

Introducción. La ingesta de alimentos poco saludables con alto contenido energético en la escuela podría influir en la ingesta energética total de los niños. Objetivo: Caracterizar los patrones de compra de snacks en el colegio y analizar la asociación de estos patrones con la procedencia del snack escolar (de la casa o comprada en el colegio) y el tiempo de pantalla. Materiales y métodos: Se realizó un estudio transversal (octubre 2018-mayo 2019) en escolares (9-12 años) Cuenca- Ecuador. La ingesta de grupos de alimentos (FG) no saludables altos en energía, la fuente del snack escolar y el tiempo de pantalla se evaluaron mediante cuestionarios. Se utilizó análisis de correspondencias múltiples para identificar patrones de ingesta de FG poco saludables y la regresión logística para evaluar asociación entre la ingesta FG no saludables con la fuente del snack escolar. Resultados: En 1.028 niños 63%, 42%, 30% y 22% declararon consumir dulces/golosinas, aperitivos salados, comida rápida y productos de pastelería, respectivamente, al menos dos/días/ semana. Un 39% fueron clasificados como "Consumidores frecuentes de FG poco saludables de alta densidad energética". La compra de los snacks en el colegio se asoció con una ingesta más frecuente de dulces/golosinas (OR=1,56; IC95%=1,05-2,32) y comida rápida (OR=2,01; IC95%=1,15-3,50) durante la semana y con la clasificación en el grupo" consumidores frecuentes de FG poco saludables de alta densidad energética" (OR=1,99; IC95%=1,40- 2,82). Conclusiones: Los niños ecuatorianos aún consumen alimentos no saludables prohibidos en la escuela. Estos resultados refuerzan la importancia de evaluar, monitorear y adaptar estrategias para promover una dieta balanceada(AU)

[Nutritional traffic light system for processed foods: qualitative study of awareness, understanding, attitudes, and practices in Ecuador]. / Semáforo nutricional de alimentos procesados: estudio cualitativo sobre conocimientos, comprensión, actitudes y prácticas en el Ecuador.

OBJECTIVES.: To analyze awareness, understanding, attitudes, and practices related to the nutritional traffic light system (NTLS) on processed food packaging in Ecuador. MATERIALS AND METHODS.: 21 discussions were held in focus groups (FG) in populations of various sizes in the coastal, mountainous, and eastern regions. Nine interviews were conducted with key informants (KI) representing large, medium, and small enterprises producing or selling processed foods. RESULTS.: There were 171 FG participants, the majority of whom recognized and understood the NTLS. There was a certain amount of discussion around awareness of the NTLS and purchasing attitudes, and other factors such as taste, brand, or accessibility were considered. Attitudes were different between age groups: while the group of five- to nine-year-olds knew little about the NTLS and preferred homemade foods, the group of 15- to 19-year-olds was indifferent to the NTLS information and placed more value on other features, such as taste. Practices related to the purchase and consumption of processed foods highlighted seven different strategies that ranged from replacing the product to ignoring the NTLS information. The KIs did not agree with the policy, but they acknowledged having amended the content of some products to reduce fat, sugar, and salt. CONCLUSIONS.: The NTLS has had a positive effect on awareness and understanding of the content of processed products. Practices related to purchasing and consuming processed foods would be improved by promotion of the nutritional labeling policy, trade control, and the monitoring and surveillance of its implementation.

The double burden of undernutrition and excess body weight in Ecuador.

BACKGROUND: Ecuador's current nutrition policies have not taken adequate notice of the double burden of malnutrition and continue to focus on stunting and to a lesser extent on overweight, without addressing the simultaneous presence of undernutrition, micronutrient deficiencies, and overweight or obesity (OW/OB). OBJECTIVE: The aim of this article was to describe the prevalence and distribution of undernutrition (stunting, anemia, and zinc deficiency), overweight, and obesity in Ecuador to explore the evolving double burden of malnutrition at the national, household, and individual levels and to discuss whether current public health policies are addressing the double burden. DESIGN: Data from the 2012 Ecuadorian National Health and Nutrition Survey (ENSANUT-ECU) was used to estimate the dual burden of malnutrition at the national, household, and individual levels in children <5 y old, school-aged children, and women of reproductive age. RESULTS: In 13.1% of households, mothers with excess body weight coexist with a stunted child <5 y old. Moreover, among households with overweight or obese mothers, 12.6% have an anemic child and 14% have a zinc-deficient child. At the individual levels, the coexistence of OW/OB and stunting, anemia, or zinc deficiency was found in 2.8%, 0.7%, and 8.4% of school-aged children, respectively. In addition, 8.9% and 32.6% of women aged 12-49 y have excess body weight and anemia or zinc deficiency, respectively. CONCLUSIONS: This article shows the coexistence of high rates of undernutrition and OW/OB at the individual, household, and national levels in Ecuador. Although integrated approaches to address the emerging double burden are required, public health policies to date have not responded adequately.

Decreased serum level of miR-146a as sign of chronic inflammation in type 2 diabetic patients.

BACKGROUND: There is increasing evidence that chronic inflammation is an important determinant in insulin resistance and in the pathogenesis of type 2 diabetes (T2D). MicroRNAs constitute a newly discovered system of cell regulation and in particular two microRNAs (miR-146a and miR-155) have been described as regulators and biomarkers of inflammation. AIM: To determine a putative association between the levels of miR-146a and miR-155 in serum of T2D patients, clinical parameters and serological indicators of inflammation. METHODS: We performed quantitative Real Time PCR (qPCR) of microRNAs from serum (56 Ecuadorian T2D ambulatory patients and 40 non-diabetic controls). In addition, we evaluated T2D-related serum cytokines.chemokines and growth factors using a commercially available multi-analyte cytometric bead array system. We correlated outcomes to clinical parameters, including BMI, HbA1c and lipid state. RESULTS: The Ecuadorian non-diabetic controls appeared as overweight (BMI>25: patients 85%, controls 82.5%) and as dyslipidemic (hypercholesterolemia: patients 60.7%, controls 67.5%) as the patients. The serum levels of miR-146a were significantly reduced in T2D patients as compared to these non-diabetic, but obese/dyslipidemic control group (mean patients 0.61, mean controls set at 1; p = 0.042), those of miR-155 were normal.The serum levels of both microRNAs correlated to each other (r = 0.478; p<0.001) and to leptin levels. The microRNAs did not correlate to BMI, glycemia and dyslipidemia.From the tested cytokines, chemokines and growth factors, we found IL-8 and HGF significantly raised in T2D patients versus non-diabetic controls (p = 0.011 and 0.023 respectively). CONCLUSIONS: This study shows decreased serum anti-inflammatory miR-146a, increased pro-inflammatory IL-8 and increased HGF (a vascular/insular repair factor) as discriminating markers of failure of glucose control occurring on the background of obesity and dyslipidemia.

Semáforo nutricional de alimentos procesados: estudio cualitativo sobre conocimientos, comprensión, actitudes y prácticas en el Ecuador / Nutritional traffic light system for processed foods: qualitative study of awareness, understanding, attitudes, and practices in Ecuador

RESUMEN Objetivos. Analizar los conocimientos, comprensión, actitudes y prácticas relacionadas al semáforo nutricional (SN) en envases de alimentos procesados en el Ecuador. Materiales y métodos. Se realizaron 21 discusiones de grupos focales, en poblaciones de diverso tamaño de las regiones de costa, sierra y oriente. Se condujeron nueve entrevistas a informantes claves (IC) con representantes de empresas grandes, medianas y pequeñas que producían o comercializaban productos procesados. Resultados. Fueron 171 participantes de GF; en su mayoría reconocían y comprendían el SN. Hubo cierta disociación entre los conocimientos del SN y la actitud de compra, pues también se consideraba otros factores como el sabor, la marca o la accesibilidad. Las actitudes fueron diferentes entre grupos etarios: mientras que el grupo de 5 a 9 años conocía poco sobre el SN y prefería alimentos caseros, el grupo de 15 a 19 años era indiferente a la información del SN y daba más valor a otras características como el gusto. Las prácticas relacionadas a la compra y el consumo de alimentos procesados revelaron, siete estrategias diferentes que iban del reemplazo del producto a ignorar la información del SN. Los IC no concordaban con la política, pero reconocían haber modificado el contenido de algunos productos para reducir las concentraciones de grasa, azúcar y sal. Conclusiones. El SN ha tenido un efecto positivo en el conocimiento y comprensión del contenido de los productos procesados. Las prácticas relacionadas a la compra y consumo de alimentos procesados mejorarían a través de la promoción de la política del etiquetado nutricional, control de la comercialización, y el monitoreo y la vigilancia de su implementación.

Social inequality and child malnutrition in four Andean countries.

OBJECTIVE: To analyze the effects of socioeconomic, regional, and ethnic conditions on chronic malnutrition in four Andean countries of South America: Bolivia, Colombia, Ecuador, and Peru. METHODS: The study was based on Demographic and Health Surveys (DHS) for Colombia (1995), Peru (1996), and Bolivia (1997), and on a Living Standard Measurement Survey for Ecuador (1998). We developed an index of household socioeconomic status using categorical principal components analysis. We broke down the prevalence of stunting by socioeconomic status (SES), ethnicity, place of residence (large cities, small cities, towns, and countryside), and region (highland region versus other areas of the country). We applied smoothed regression curves and linear functions to analyze SES effects on stunting, with specific models for Bolivia, Ecuador, and Peru. RESULTS: Bolivia, Ecuador, and Peru have similar characteristics, with high stunting prevalences overall; higher stunting prevalences in their highland areas, particularly among indigenous populations; and strong socioeconomic disparities. Colombia, in contrast, has a lower stunting prevalence and smaller regional disparities. The socioeconomic gradient of stunting is strong in all four countries, with prevalence rates in the poorest deciles at least three times as high as those in the top decile. DISCUSSION: The sharp contrast between the conditions found in Bolivia, Ecuador, and Peru and those in Colombia may be the result of specific ethnic factors affecting indigenous groups; a particular diet profile in the highland areas, with low protein and micronutrient intake; and differences in the long-term economic and social development paths that the countries have taken. Along with the strong socioeconomic gradient in all the countries, the weight of ethnic and regional factors suggests the need to reduce inequality as well as to comprehensively improve education and housing, better target health and nutrition programs, and implement participatory programs integrated into indigenous cultures.
