Inseguridad alimentaria y hábitos alimentarios durante la pandemia de COVID-19 en hogares chilenos / Effects of COVID-19 pandemic on food insecurity perception in Chilean households

Background: The coronavirus 2 pandemic (COVID-19) has caused intense changes in lifestyles, feeding, and nutrition habits. Aim: To analyze food insecurity and eating habits during the period of quarantine in a group of Chilean individuals. Material and Methods: An online survey was conducted in 2,767 households with questions about the sociodemographic composition of the household, household food purchasing habits in the quarantine period for COVID-19, and perception of food insecurity. Results: More than 60% of households (p < 0.01) were worried about not having enough food, especially when children under 18 years of age lived in them. This perception increased in urban households (p < 0.01) and those located in the Central-Southern and Southern regions (p < 0.01). During the pandemic, the consumption of healthy products such as milk increased in 50% of households, legumes in 72%, eggs in 79%, fruits in 54%, vegetables in 67% and water in 81%. There was also a lower consumption of unhealthy and ultra-processed foods such as hot-dogs in 90% of households, sausages in 73%, sugary drinks in 79% and ice cream in 83%. Conclusions: The COVID-19 pandemic in Chile increased the perception of food insecurity in households with vulnerable conditions. However, the consumption of healthier foods increased.

Hábitos alimentarios y estado nutricional de niños y niñas que asisten a las Escuelas Deportivas Integrales del Instituto Nacional de Deporte, Región de Ñuble / Eating habits and nutritional status of children attending the Integral Sports Schools of the National Sports Institute, Ñuble Region, Chile

RESUMEN La malnutrición por exceso se ha convertido en un problema de salud pública a través de todo el ciclo vital. El objetivo del estudio fue analizar los hábitos alimentarios y el estado nutricional de niños y niñas que asisten a las Escuelas Deportivas Integrales (EDI) del Instituto Nacional de Deporte en la comuna de Chillán. Se realizó evaluación antropométrica y aplicación de encuesta sobre hábitos alimentarios, que permitía medir alimentos consumidos de manera diaria, semanal y mensual de: frutas, verduras, lácteos, agua, carne, pescado, legumbres, golosinas dulces y saladas, productos fritos, comida rápida y embutidos. En los resultados, se confirma una alta prevalencia de malnutrición por exceso (58,7%). Para el cumplimiento de las Guías Alimentarias Basadas en Alimentos (GABAS) para la población chilena, se observó sólo un 59,2% en frutas, 71,4% para verduras, 13,8% en pescado, 39,3% en legumbres y 66,3% en lácteos. Diariamente, más del 65% consume golosinas dulces y/o saladas. Semanalmente, la comida rápida y productos fritos se ingieren en un 66% y 79% respectivamente. Se sugiere la necesidad de realizar intervenciones multidisciplinarias de prevención y promoción de la salud, orientadas a mejorar estilos de vida saludables en la población infantil y así contribuir a disminuir los índices de morbilidad infantil.

ABSTRACT Over nutrition has become a public health problem over the life cycle. The objective of the study was to analyze the eating habits and nutritional status of children attending the Integral Sports Schools (ISS) of the National Sports Institute in Chillán, Chile. An anthropometric evaluation was performed; an eating habits survey, which measured the consumption of fruit, vegetables, dairy products, water, meat, fish, legumes, sweet and salty treats, fried products, junk food, and cold meats on a daily, weekly, and monthly basis was completed. Results confirmed a high prevalence of overnutrition (58.7%). Complying with Food Based Dietary Guidelines for the Chilean Population, values were 59.2% for fruit, 71.4% for vegetables, 13.8% for fish, 39.3% for legumes, and 66.3% for dairy products. More than 65% of the children ate sweet and/or salty treats on a daily basis. Weekly intake of junk food and fried products was 66% and 79%, respectively. Multidisciplinary prevention and health promotion interventions are required to improve healthy lifestyles in children and thus contribute to reducing child morbidity rates.

Una mirada actualizada sobre los ambientes alimentarios y obesidad / An updated look at food environments and obesity

La obesidad es considerada por la Organización Mundial de la Salud como un gra-ve problema de salud pública. En Chile los datos de la Encuesta Nacional de Salud 2016-2017 muestran que 7 de cada 10 chilenos presentan sobrepeso u obesidad y, según datos del Ministerio de Educación, en los niños que ingresan a la enseñanza básica, la prevalencia de obesidad no ha logrado bajar del 25%. En los últimos años ha habido un reconocimiento mundial sobre la influencia que tienen los Ambien-tes Alimentarios en el comportamiento de las personas y en el estado nutricional de las poblaciones. Recientemente en el país se han identificado los Ambientes Ali-mentarios predominantes y sus factores condicionantes, lo que ha culminado con la elaboración de la Política Nacional de Alimentación y Nutrición y los lineamientos que permiten avanzar en diferentes estrategias para modificar dichos ambientes. En Chile se han implementado medidas individuales y estructurales que han tenido gran relevancia tanto a nivel nacional como internacional, aunque está pendiente la ela-boración de instrumentos que midan de manera objetiva y confiable los Ambientes Alimentarios

The World Health Organization considers obesity to be a serious public health pro-blem. In Chile, results from the 2016-2017 National Health Survey show that 7 in 10 Chileans are overweight or obese, and according to the Ministry of Education, the prevalence of obesity among children entering elementary school has not dropped below 25%. In the last few years, Food Environments have been widely recognized for their impact on the behavior and the nutritional status of different populations.The principal Food Environments and their conditioning factors have been recently identified in Chile, and this information has been used to elaborate the National Food and Nutrition Policy and the inform guidelines and strategies to modify these environments. The individual and structural measures implemented in Chile have proven relevant, both on a national scale, as well as internationally; nevertheless, the development of instruments to objectively and reliably measure Food Environments is still pending

Ingesta de alimentos proteicos en adolescentes de la ciudad de Chillán, Chile / High-protein foods intake by adolescents in Chillan, Chile

RESUMEN El objetivo del estudio fue analizar la ingesta de alimentos proteicos distintos de los lácteos y sus derivados, en adolescentes que asisten a un establecimiento educacional subvencionado en la comuna de Chillán. Se realizó un estudio analítico de corte transversal, con una muestra de 154 adolescentes de edades entre 14 y 17 años. Se evaluó estado nutricional según IMC e ingesta alimentaria mediante encuesta de frecuencia de consumo cuantificado, con énfasis en la ingesta de alimentos de origen proteico distinto de los lácteos. El 90% de los encuestados, independiente del sexo, consumió semanalmente legumbres, carnes, pescados y mariscos. Las medianas de consumo de carnes, alcanzó los 275 g en hombres y 191 g en mujeres (p<0,01). Los hombres consumieron 1,5 veces más embutidos que las mujeres (148 g v/s 89 g; p=0,02). Al comparar la ingesta de los alimentos proteicos estudiados, con la Guía Alimentaria para los adolescentes, el 60% presentó un bajo cumplimiento de ingesta semanal en carnes, huevos, pescados y mariscos, por lo que es imperativo implementar estrategias tendientes a mejorar el consumo de alimentos con proteínas de alto valor biológico que les permitan un adecuado desarrollo.

ABSTRACT The objective of the present study was to analyze the intake of high-protein foods, other than dairy products and their derivatives, by adolescents attending a subsidized school in the city of Chillán, Chile. A cross-sectional analytic study was conducted with a sample of 154 adolescents between the ages of 14 and 17. Nutritional status was evaluated using body mass index (BMI) and food intake was measured using a quantified food consumption trend survey emphasizing the consumption of high-protein foods other than dairy products. Ninety percent of surveyed subjects, independently of sex, consumed legumes, meat, fish, and seafood on a weekly basis. Median weekly consumption of meat was 275 g for boys and 191 g for girls (p<0.01). Boys consumed 1.5 times more sausages than girls (148 g vs. 89 g; p=0.02). When comparing food intake of the high-protein foods under study with the Chilean Food Guide for adolescents, 60% complied poorly with weekly intake of meat, eggs, fish, and seafood. It is therefore imperative to implement strategies to improve the consumption of foods with high levels of biological protein to ensure the adequate development of adolescents.
