Translation and Validation of the Nutrition for Sport Knowledge Questionnaire in Brazil (NSKQ-BR).

This study aimed to translate, culturally adapt, and validate "The Nutrition for Sport Knowledge Questionnaire (NSKQ)" for Brazilian athletes. The NSKQ is an Australian instrument composed of 87 questions divided into six subsections (weight control, macronutrients, micronutrients, sports nutrition, supplementation, and alcohol) designed to assess the nutritional knowledge (NK) of athletes. The translation process followed the recommendations of the World Health Organization for translating and adapting instruments. Semantic validation involved a panel of specialists (n = 21), followed by an assessment performed by a group of adult Brazilian athletes from various sports (n = 17). The reproducibility and internal consistency of the questionnaire were evaluated via a test-retest approach in a sample of adult Brazilian athletes (n = 29) from diverse sports, who completed the Brazilian version of the NSKQ (NSKQ-BR). Overall, the NSKQ-BR presented good internal consistency (α = 0.95) and reproducibility (intraclass correlation coefficient (ICC) = 0.85). The factors "sports nutrition" and "alcohol" showed moderate reproducibility (ICC = 0.74 (0.46-0.88) and ICC = 0.68 (0.33-0.85), respectively). Most athletes (n = 17; 58.6%) presented a medium NK score (50-65%). The NSKQ-BR is available to evaluate the NK levels of Brazilian athletes. The NSKQ-BR presented high internal consistency and reproducibility, validating its applicability among adult athletes across diverse sports.

Impact of a Nutrition Education Intervention on Knowledge, Healthy Eating Index, and Biochemical Profile in a Rural Community in Peru.

Background: Non-communicable diseases in adults and anemia in children represent a major global public health problem, with multiple causes including poor dietary quality. However, nutrition education interventions can empower individuals to make appropriate dietary changes. Objective: To evaluate the impact of a nutritional education intervention on nutrition knowledge (NK), healthy eating index (HEI), and biochemical profile in families in the community in Peru. Methods: A pre-experimental study was conducted in the community of Sinchicuy, located on the banks of the Amazon River, Iquitos, Peru. Nutrition education was provided over a 16-week period to a total of 61 heads of household (23 children under 5 years of age and 23 older adults). Fasting glucose and hemoglobin (Hb) concentration analyses were also carried out before and after the intervention. Results: After the intervention, a significant improvement in the NK score was observed, increasing by 90% (p < 0.001). Additionally, the average HEI scores experienced a significant increase, rising by approximately 11.4% (p < 0.001). In children under 5 years of age, the Hb level showed a significant increase of 5.1% (p = 0.017). However, no statistically significant difference in glucose concentration was observed in older adults after the intervention. Conclusion: The findings of this study indicated a positive impact on NK, HEI, and Hb in heads of households, older adults, and children under five in a rural community where there is limited access to basic services.

Nutritional Knowledge about Maternal and Newborn Health among Physiotherapists during the COVID-19 Pandemic in Minas Gerais, Brazil.

Adequate nutrition before and during pregnancy, as well as postpartum, is among the major contributors to maternal and newborn health. Physiotherapists' knowledge of this area is still scarce, although their clinical practice has been linked to newborns' neuropsychomotor development, which, in turn, is influenced by maternal health and nutritional status. Therefore, this study aimed to evaluate the nutritional knowledge of physiotherapists regarding maternal and newborn health. A total of 70 Brazilian physiotherapists (32.2 ± 6.0 years; 72.9% females) were evaluated between November 2019 and February 2020 for their sociodemographic characteristics, professional experience, and nutritional knowledge about maternal and newborn health through a validated questionnaire personally administered by the same trained researcher. Most of the physiotherapists had graduated but had no specialization in maternal and child physiotherapy (96.1% of the females and all the males). The nutritional knowledge about maternal and newborn health was significantly different between the female and male health professionals, as well as between the less and more experienced participants, i.e., female physiotherapists and the more experienced ones had more correct answers on the nutritional questionnaire than the male and less experienced physiotherapists, respectively (p < 0.05). Our results open an interesting window for the future education and training of Brazilian physiotherapists in nutrition.

A systematic review of the effects of nutrition programmes in high schools

Introduction/Objectives: Obesity rates are reaching alarming levels. Adolescence is a critical period for the prevention of nutritional problems, as it is a time of development of one's own eating habits. These habits will persist into adulthood, so showing adolescents healthy lifestyle patterns is important. The ideal option would be through school-based nutrition intervention programmes. The main objective of this article is to investigate the effectiveness of intervention programmes based on nutritional knowledge and the behaviour of adolescents aged 11-19 years. Method: To carry out this systematic review we employed Scopus, PubMed, and Web of Science as databases and a search period that spanned the last 10 years, following the PRISMA statement. Subsequent to the search, 110 articles were found. Finally, 19 articles were selected for in-depth analysis after a thorough screening. Results: The results show that, in general, intervention programmers have improved the nutritional knowledge of high school students, which means an improvement in their eating behaviours. In addition, these programmes increase their levels of physical activity. However, gender differences are observed, with girls being more concerned about maintaining a balanced diet. Conclusion: In conclusion, schools are an ideal environment for developing programmes that interfere in adolescent eating behaviour.

Introducción/Objetivos: Las tasas de obesidad están alcanzando niveles alarmantes. La adolescencia es un periodo crítico para la prevención de problemas nutricionales, ya que es un momento de desarrollo de los propios hábitos alimentarios. Estos hábitos permanecerán en la edad adulta, por lo que es importante mostrarles a los adolescentes patrones de estilo de vida saludable. La opción ideal sería a través de programas de intervención nutricional en las escuelas. El objetivo principal de este artículo es investigar la efectividad de los programas de intervención basados en el conocimiento y comportamiento nutricional en adolescentes de 11 a 19 años. Métodos: Para llevar a cabo esta revisión sistemática utilizamos como bases de datos Scopus, PubMed y Web of Science y un periodo de búsqueda que abarcó los últimos diez años, siguiendo la declaración Prisma. Después de la búsqueda, se encontraron 110 artículos. Finalmente, 19 artículos fueron seleccionados para un análisis en profundidad después de una revisión exhaustiva. Resultados: Los resultados muestran que, en general, los programas de intervención han mejorado los conocimientos nutricionales de los estudiantes de secundaria, lo que significa una mejora en sus conductas alimentarias. Además, estos programas aumentan sus niveles de actividad física. Sin embargo, se observan diferencias de género, estando las chicas más preocupadas por mantener una dieta equilibrada. Conclusiones: En conclusión, las escuelas son un ambiente ideal para el desarrollo de programas que interfieren en la conducta alimentaria de los adolescentes.

Hábitos de alimentación infantil y su relación con las prácticas y conocimientos nutricionales parentales

Objetivo: Evaluar la relación entre las prácticas parentales de alimentación, los conocimientos nutricionales de los padres y los hábitos de alimentación infantil reportados por padres de cuatro instituciones educativas del suroccidente de Colombia. Método: Estudio observacional con diseño transversal correlacional. Se analizaron los datos de 1.162 padres de niñas y niños matriculados en los grados de preescolar hasta tercero de primaria de cuatro instituciones educativas públicas, quienes contestaron cuestionarios de autoinforme. Se realizaron análisis descriptivos e inferenciales. Resultados: La dieta de las niñas y los niños se caracteriza por un consumo frecuente de alimentos ultraprocesados y un consumo de frutas y verduras menor de lo esperado. Se encontraron relaciones entre las prácticas parentales de alimentación responsivas y el consumo de alimentos saludables en los hijos, así como entre las prácticas autoritarias y permisivas con el consumo frecuente de alimentos ultraprocesados. El nivel de conocimiento nutricional de los padres no se relacionó con la dieta de las niñas y los niños; sin embargo, se encontró una relación entre las prácticas parentales responsivas, un bajo nivel de conocimientos nutricionales de los padres y una baja frecuencia de consumo de frutas y verduras en los hijos. Conclusión: La alimentación es un fenómeno complejo, e implica la interacción entre los factores individuales y contextuales; en esta medida, la promoción de hábitos saludables involucra un trabajo conjunto en los múltiples niveles de interacción. Se espera que los resultados de este estudio posibiliten la construcción de intervenciones interdisciplinares oportunas, en poblaciones de bajos y medios ingresos en el territorio observado.

Purpose: To evaluate the relationship between parental feeding practices, parental nutritional knowledge, and child feeding habits reported by parents in four educational institutions in southwestern Colombia. Method: Observational study with correlational cross-sectional design. Data were analysed from 1.162 parents of children enroled in grades from preschool to third grade from four public educational institutions. Parents answered self-report questionnaires. Descriptive and inferential analyses were performed. Results: The children's diet is characterised by frequent consumption of ultra-processed food and a lower consumption of fruits and vegetables. Relationships were found between responsive parenting practices and healthy food consumption in children, as well as between authoritarian and permissive practices with frequent consumption of ultra-processed foods. The level of nutritional knowledge of parents was not related to the children's diet; however, a relationship was found between responsive parenting practices, a low level of nutritional knowledge of parents, and a low frequency of fruit and vegetable consumption in children. Conclusion: Eating is a complex phenomenon and involves the interaction between individual and contextual factors. To this extent, the promotion of healthy habits involves joint work at multiple levels of interaction. The results of this study are expected to allow the construction of timely interdisciplinary interventions in low- and middle-income populations in the observed territory.

Nutritional knowledge plays a fundamental role in the formation of dietary habits and the modulation of eating behaviour. Nutrition and diet are crucial during adolescence, especially for young athletes. The purpose of this research was to analyse the theoretical validity and indices of discrimination and difficulty of the questionnaire on nutritional knowledge applied in sports using item response theory in youth athletes aged 14 to 19. This instrumental study was conducted in five phases: item generation, expert panel review, pilot testing, application, and final refinement. A total of 261 adolescents aged 14 to 19, who were members of national team and collective disciplines of professional clubs, participated. Difficulty and discrimination indices were determined for each item. Items 1 (0.354) and 2 (0.285) of the before factor, 3 (0.315) and 6 (0.408) of the during factor, 7 (0.354) and 10 (0.408) of the post factor, 3 (0.254) and 9 (0.231) of the hydration factor, and 2 (0.362) and 5 (0.323) of the supplementation factor showed the highest degree of discrimination. The questionnaire on nutritional knowledge applied in sports consists of 30 items divided into five factors, each with six items. The initial questionnaire proposal is a theoretically valid tool and with adequate difficulty and discrimination indices to evaluate nutritional knowledge in young athletes. Its application allows for identifying potential gaps in key knowledge and designing specific educational strategies to address them.

¿La Calidad De La Alimentación En Individuos Que Realizan Actividad Física Regular, Se Ve Afecta Por Conocimientos Y Prácticas Nutricionales?: Un Estudio Transversal

Antecedentes: Este estudio tuvo como objetivo determinar la relación entre la calidad de la dieta y el conocimiento sobre nutrición (CN) y las prácticas de nutrición (PN) de las personas que realizan actividad física (AF) con regularidad. Métodos: Se estudiaron 200 individuos sanos que acudían al gimnasio al menos tres veces por semana. La calidad de la dieta se calculó utilizando el Índice de Alimentación Saludable-2015 (HEI-2015). Se utilizaron modelos de regresión lineal múltiple para evaluar las asociaciones entre las puntuaciones de CN y PN y las variables de la dieta. Resultados: De los participantes, el 47,0 % tenía CN deficiente y el 48,0 % tenía PN pobre. Se determinó que las puntuaciones de PN se asociaron significativamente con los granos integrales, los mariscos y las proteínas a base de hierbas y la calidad total de la dieta (p0,05). Un aumento en una unidad en la puntuación CN resultó en un aumento del 26,7 % en el consumo de refrigerios ajustado por edad, sexo, nivel educativo, índice de masa corporal (IMC), tabaquismo, consumo de alcohol y actividad física (AF)(p<0,001). La evaluación del puntaje PN se relacionó con las comidas principales (β=0,065±0,013; IC 95% 0,04-0,09; p<0,001), consumo de refrigerios (β=0,029±0,014, IC 95% 0,01-0,06; p<0,05) y la calidad total de la dieta (β=0,894±0,329; IC95% 0,24-1,54; p<0,05). Además, alrededor del 17% de la variabilidad en la puntuación PN podría explicarse por las puntuaciones CN. Conclusiones: CN elevada se asoció con un aumento en las puntuaciones de PN e indirectamente con un aumento en la calidad de la dieta. Para ver los efectos beneficiosos de la AF en la salud, las personas deben apoyarse en una dieta saludable, aumentando su CN.

Background: This study aimed to determine the relationship between diet quality and nutrition knowledge (CN) and nutrition practices (NP) of people who perform physical activity (PA) regularly. Methods: Two hundred healthy individuals who attended the gym at least three times a week were studied. The quality of the diet is calculated using the Healthy Eating Index-2015 (HEI-2015). Linear regression models were used multiplex to assess associations between NC and PN scores and dietary variables. Results: Of the participants, 47.0% had poor NK and 48.0% were found to have poor NPs.It was determined that NP scores were significantly associated with whole grains, seafood, and herbal proteins and total diet quality (p0.05). A one-unit increase in the NK score resulted in a 26.7% increase in the consumption of snack meals adjusted for age, gender, educational level, body mass index(BMI), smoking status, alcohol consumption, and physical activity(PA)(p< 0.001). Assessment of the NP score was related to the main meals (β=0.065±0.013; 95%CI 0.04-0.09; p<0.001), consumption of snack meals (β=0.029±0.014, 95%CI 0.01-0.06; p<0.05), and total diet quality(β=0.894±0.329; 95%CI 0.24-1.54; p<0.05). Moreover, about 17% of the variability in the NP score could be explained by the NK scores. Conclusions: Elevated NK was associated with an increase in the NP scores and indirectly with an increase in diet quality. In order to see the beneficial effects of PA on health, individuals should be supported by a healthy diet, by increasing their NK.

Stages of change and self-efficacy are related to consumption of food markers among Brazilian adolescents and young adults.

Objective: This study aimed at analyzing the association between stages of change, consumption of food markers, and self-efficacy in the adoption of healthy eating practices, adjusted by nutritional knowledge, among Brazilian adolescents and young adults. Methods: A cross-sectional analysis was conducted with 347 individuals from schools in the Federal District, Brazil. They completed a self-administered questionnaire covering: consumption of food markers, stage of change, self-efficacy in the adoption of healthy eating practices, and nutritional knowledge. Adjusted logistic regression was conducted. Results: Participants in pre-contemplation (OR = 0.22), contemplation (OR = 0.19), decision (OR = 0.13) and action (OR = 0.40) stages have less chance to have healthy eating than those in maintenance, including fruits and vegetables [pre-contemplation (OR = 0.23), contemplation (OR = 0.19), and decision (OR = 0.09)]. Adolescents and young adults in pre-contemplation (OR = 0.29) and contemplation (OR = 0.37) had lower chances of having low consumption of sugar-sweetened beverages compared to those in maintenance (p < 0.05). Adolescents and young adults in pre-contemplation (OR = 0.38) and contemplation (OR = 0.36) were less likely to have high self-efficacy scores than those in maintenance (p < 0.05). Higher score of self-efficacy was associated with a lower chance of having a high consumption of sugar-sweetened beverages (OR = 1.02; p = 0.032). Conclusion: Regardless of nutritional knowledge, individuals in the earlier stages of change are less likely to have an adequate consumption of healthy foods markers, including fruits and vegetables, and low sugar-sweetened beverages consumption. They are also less likely to have high self-efficacy scores than those in maintenance. Nutritional interventions to focus on enhancing self-efficacy among adolescents and young adults in earlier stages of change to improve dietary habits.

Effectiveness of a Program Based on Telehealth in Nutritional Knowledge and Body Mass Index in Peruvian University Teachers.

BACKGROUND: University teachers, as agents of socialization, are one of the most influential groups in improving public health, and their nutritional knowledge can influence both the eating behavior of students and the family. OBJECTIVE: This study was carried out to evaluate the effect of a telehealth program on the level of nutritional knowledge and body mass index (BMI) of university teachers. METHODS: A pre-experimental study was carried out from August to December 2020. A pretest and a posttest were applied. The number of teachers in the initial test was 88 and those included in the final evaluation, 83; and they were selected by nonprobability sampling for convenience. The telehealth-based program lasted 18 weeks and included basic information on nutrition and motivational messages. Sociodemographic and anthropometric data were collected through a predesigned questionnaire before and after the educational program. RESULTS: Posttest knowledge scores increased significantly from 6.40 ± 1.70 to 10.59 ± 1.18 (P < .001). In relation to time, significant variations are observed in weight measurements (P < .001), BMI (P < .001), and basic nutritional knowledge (P < .001) before and after the intervention program. CONCLUSION: The telehealth-based intervention improved basic nutritional knowledge levels and BMI. Likewise, the current findings provide evidence on the importance and need to develop future nutritional education programs that comprehensively encompass all study plans for the benefit of the university community.

"Eating healthy": Distrust of expert nutritional knowledge among elderly adults.

Elderly adults in southern Ecuador often distrust nutritionists' advice when implementing changes to their dietary practices. This distrust is no overt disregard for expert nutritional knowledge but rather the result of structural and situated practices that combine suspicion, misinformation, financial limitations, and family care. In this article, we examine eating practices among elderly adults in southern Ecuador in order to understand how nutrition distrust is constructed. In doing so, our aim is to understand how elderly adults incorporate-or not-expert nutritional knowledge into their eating practices. By ethnographically documenting daily eating practices among elderly adults in their homes, alongside expert nutritional discourses, our findings reveal that there is first, a local understanding of "eating healthy" connected to lived realities (e.g. farming practices, agricultural toxicity, age, education, polypharmacy, kinship ties), and second, a disconnect between expert nutritional knowledge and eating practices linked to how knowledge is produced and disseminated (e.g. power relations, scientific vocabulary, perceptions of health). Understanding how elderly adults build trust around eating can be a fertile ground for promoting more effective and suitable dietary advice among specific communities or groups like elderly adults.

Knowledge and food practices questionnaire: construction and validation

Abstract Objectives: To develop and validate an instrument about nutritional knowledge and feeding practices to be used in children aged 7-11 years, based on the latest Brazilian Food Guide. Methods: Review on the subject; instrument creation; content validity with two groups of judges: first, nutritionists and, after adjustments, a multidisciplinary group (content validity index [CVI]); FACE validity; reproducibility analysis (intraclass correlation coefficient [ICC], level of agreement, and kappa [k]); internal consistency analysis (Cronbach's alpha[α]) and construct validity (Kaiser-Meyer-Olkin and exploratory factorial analysis). The sample was calculated, considering at least ten subjects for each question of the questionnaire. Results: There was a final sample of 453 children (53.6% girls), with a mean age of 9.45 years (SD = 1.44). The content validity showed a CVI ≥ 0.80 for relevance in 62.3% of the items for nutritionists' group and 100% of the items for the multidisciplinary group, clarity (49.4%, 91.8%), and pertinence (58.8%, 98.4%), respectively. The test-retest showed a level of agreement of 84.3% and k = 0.740 for the Knowledge dimension and ICC = 0.754 for the Food Practices dimension. The internal consistency showed α = 0.589 for the Knowledge dimension and α = 0.618 for the Food Practices dimension. For the construct validity, Kaiser-Meyer-Olkin was 0.724 and exploratory factorial analysis showed a variance of 47.01 with varimax rotation and defined five factors for the Practices Dimension. Conclusion: The Food Knowledge and Practices Questionnaire (Questionário de Conhecimento e Práticas Alimentares [QCPA]) instrument showed validity and reliability to assess nutritional knowledge and food practices in children aged 7-11 years.

Educación nutricional bajo el paradigma crítico-dialéctico en una comunidad: avances preliminares / Nutritional education under the Critic-Dialectic Paradigm in a community: Preliminary contributions

La alta frecuencia de sobrepeso, obesidad y síndrome metabólico producto de malos hábitos alimentarios en la comunidad del sector "José Ignacio Acevedo" municipio Los Guayos, Estado Carabobo es lo que nos motiva a promocionar hábitos alimentarios saludables. Estos tres elementos son el sustrato de un grupo de patologías conocidas como "enfermedades crónicas no transmisibles", que impactan en la calidad de vida y en las expectativas de vida de la población. El propósito del artículo fue generar un enfoque de educación nutricional que posibilite la socialización del conocimiento nutricional en comunidades de escasos recursos económicos desde el paradigma critico-dialectico y adaptado a sus necesidades de salud, lo cual va a permitir que las soluciones se generen entre sus propios miembros, producto de los acuerdos y del consenso de manera que avancen hacia la mejora de su alimentación y su salud. Por la alta incidencia de sobrepeso, obesidad y síndrome metabólico en la comunidad, consideramos que la mejor manera para abordar esta problemática es proponer una estrategia educativa que permita el empoderamiento de un conocimiento nutricional consensuado y en construcción, no impuesto, que valore sus creencias, que les resulte amigable y por lo tanto aceptable y de fácil difusión entre ellos y ellas. Atreverse a configurar las bases educativas que cimentarán la socialización del conocimiento nutricional permitirá favorecer el cambio en los determinantes de los problemas de salud relacionados con la alimentación que tiene esta comunidad.

The high frequency of overweight, obesity and metabolic syndrome product of bad dietary habits in the community of the sector "Jose Ignacio Acevedo" Los Guayos, Carabobo State is that motivates us to promote healthy eating habits. Those three elements are the substrate of a group of pathologies known as "chronic non-communicable diseases", which have an impact on the quality of life and in the population´s expectancy of life. The purpose of the article was to generate an approach to nutritional education that will enable the socialization of the nutritional knowledge in communities with limited economic resources from the qualitative critic-dialectic paradigm and adapted to their health needs, which will allow to generate solutions among its own members, product of the arrangements and consensus towards the improvement of their diet and health. Because the high frequency of overweight, obesity and metabolic syndrome we believe that the best way to address this problem is to propose an educational strategy that will allow the empowerment of a consensual and nutritional knowledge in construction, that values their beliefs, which result them friendly and therefore acceptable and easy spread between them. Dare to configure the educational foundations that depict the socialization of the nutritional knowledge will enable us to promote the exchange of those determinants of the health problems related to the feeding in this community.

Perfil de saúde, estado nutricional e nível de conhecimento em nutrição de usuárias do Programa Academia da Cidade - Aracaju, SE / Profile of health, nutritional status and knowledge of level in nutrition Academia da Cidade Program of users - Aracaju, SE

Condições sócio-econômicas desfavoráveis, hábitos alimentares inadequados e sedentarismo representam fatores de risco para o desenvolvimento da obesidade e das doenças crônicas não transmissíveis na população. Assim, o objetivo desse estudo foi avaliar o perfil de saúde, o estado nutricional e o nível de conhecimento nutricional de mulheres praticantes de atividade física do Programa Academia da Cidade, Aracaju, SE. Foram coletados dados sócio-econômicos, condições de saúde, nutrição e conhecimento nutricional. O questionário é composto por 12 questões divididas por assunto em 3 grupos de perguntas. As medidas antropométricas aferidas foram massa corporal, estatura, perímetro da cintura e quadril. Foram avaliadas 191 usuárias do programa com média de idade de 51,9 (±9,02) anos, estando 75,4% com excesso de peso de acordo com o índice de massa corporal e 57,7 % com alto risco de desenvolvimento para doenças crônicas não transmissíveis, segundo a relação cintura-quadril. Foi observado que mulheres com maior gordura central (RCQ?0,85cm) apresentaram maior prevalência de hipertensão e diabetes (p<0,05). Cerca de 64,8 % da população apresentou conhecimento nutricional moderado com nota média de 7,0. Indivíduos com maior renda apresentaram notas significativamente maiores no conhecimento nutricional total e no grupo 2 de perguntas (alimentos fonte de fibras e gorduras) . A população estudada apresentou alta prevalência de sobrepeso e obesidade, colocando em risco seu quadro de saúde. O moderado conhecimento em nutrição e a obtenção de notas inferiores entre aqueles com menor renda mostra a necessidade do desenvolvimento de ações de educação nutricional nesta população para promoção de hábitos alimentares saudáveis.

Inadequate socioeconomic conditions, dietary habits and physical inactivity are risk factors for developing obesity and chronic diseases in population. Therefore, the aim of this study was to evaluate the health profile, nutritional status and nutritional knowledge level of women who practice physical activity from the Academia da Cidade Program, Aracaju, SE. Were collected socio-economics data, health and nutrition profiles, besides the application of a questionnaire of nutritional knowledge evaluation. The questionnaire consists of 12 questions divided by subject into three groups of questions. The anthropometric data measured were body weight, height, waist and hip circumference. Were evaluated 191 users of the program with a mean age of 51,9 years, being 45.1% overweight according to body mass index and 57.7% with high risk, according to waist-to-hip ratio risk for development of chronic diseases. Women with greater central fat (WHR ? 0.85 cm) showed a higher prevalence of hypertension and diabetes (p <0.05). About 64.8% of the population presented moderate nutritional knowledge with an average score of 7,0. Individuals with higher incomes had significantly higher scores of total nutrition knowledge and in group 2 (food source of fiber and fat) of questions. The studied population had high prevalence of overweight and abdominal obesity. The moderate knowledge in nutrition and getting lower scores among those with lower income shows the necessity of developing nutritional education activities in this population to promote healthy eating habits.

Conocimientos nutricionales y frecuencia de consumo de alimentos: un estudio de caso / Nutritional knowledge and consumption frequency of foods: a case study

El presente estudio investiga los conocimientos nutricionales de una muestra de la población de consumidores en Uruguay y su frecuencia de consumo de alimentos. 270 individuos completaron una adaptación local del General Nutrition Knowledge Questionnaire de Parmenter & Wardle y contestaron una encuesta sobre su frecuencia de consumo de 39 grupos de alimentos. Por medio de un Análisis de Conglomerados se identificaron 2 grupos de participantes con diferente nivel de conocimientos nutricionales: el clúster 1 (n = 177) y el clúster 2 (n = 93), quienes proporcionaron un valor promedio de 73.6% y 52.9% de respuestas correctas, respectivamente. Los grupos se diferenciaron en forma significativa (p ≤ 0.05) en su distribución por edad y nivel de educación, estando el clúster 1 compuesto principalmente por adultos mayores y con mayor nivel de estudios. Algunas áreas del conocimiento fueron extremadamente pobres, como ser el conocimiento sobre el número de porciones de frutas y verduras que se deberían consumir por día y el aporte calórico de los distintos nutrientes. En términos generales, los conocimientos nutricionales influyeron positivamente en la frecuencia de consumo de alimentos, dado que la población que presentó mayores conocimientos nutricionales declaró un mayor consumo de frutas y verduras y de alimentos de bajo tenor graso y un menor consumo de alimentos con alto contenido de grasas y azúcares.

The relationship between nutritional knowledge and the consumption frequency of preferred food-types was studied among one sample of Uruguayan consumers. A locally-adapted version of Parmenter & Wardle's General Nutrition Knowledge Questionnaire and a food consumption survey based on 39 food groups were completed by a total of 270 participants. Cluster Analysis enabled the identification of two clusters showing different levels of nutritional knowledge -cluster 1 (n = 177) and cluster 2 (n = 93), providing an average of 73.6% and 52.9% of correct answers, respectively. These clusters differed significantly (p ≤ 0.05) in age and educational distribution .cluster 1 was composed mainly by older adults and persons with a higher educational level. A number of areas were identified where nutritional knowledge was extremely poor, as was the case with the recommended daily fruit and vegetable intake and the caloric content of the nutrients. Overall, nutritional knowledge was found to have a positive influence on food preferences and consumption frequency, those participants with a higher nutritional knowledge reporting a higher consumption of fruits, vegetables and low-fat products, in addition to a lower consumption of high-fat and high-sugar foods.

Avaliação do conhecimento nutricional de mulheres fisicamente ativas e sua associação com o estado nutricional / Assessment of nutrition knowledge of women physically active and its relationship with nutritional status / Evaluación de conocimientos de nutrición de las mujeres físicamente activas y su relación con el estado nutricional

O objetivo do presente estudo foi avaliar o conhecimento nutricional de mulheres fisicamente ativas e correlacionar a pontuação obtida com variáveis antropométricas e nível de escolaridade. A amostra foi composta por 60 mulheres e os dados antropométricos mensurados foram massa corporal, estatura, Índice de Massa Corporal (massa corporal/estatura²) e perímetro da cintura. A amostra apresentou conhecimento nutricional moderado e correlações significativas foram obtidas da pontuação do questionário de conhecimento nutricional com o Índice de Massa Corporal (r = - 0,38, p < 0,05), perímetro da cintura (r = - 0,30, p < 0,05) e nível de escolaridade (r = 0,36, p < 0,05). O conhecimento nutricional pode estar associado com o estado nutricional e o nível de escolaridade.

The aim of the present study was to evaluate nutritional knowledge of women physically active and correlate it with anthropometric variables and educational level. The sample was composed by 60 women. The anthropometric variables measured were body weight, height, Body Mass Index (body weight/height²), waist circumference and nutritional knowledge. The sample demonstrated moderate nutritional knowledge and the questionnaire score was correlated with Body Mass Index (r = - 0,38, p < 0,05), waist circumference (r = - 0,30, p < 0,05) and educational level (r = 0,36, p < 0,05). The nutritional knowledge may be associated with nutritional and educational status.

El objetivo de este estudio fue evaluar el conocimiento nutricional de las mujeres que practican actividad física y correlacionar los resultados obtenidos con variables de la antropometría. La muestra comprende 60 personas y las variables analizadas son: Peso, estatura, el cálculo del Índice de Masa Corporal, perímetro de la cintura y conocimiento nutricional. Se observó que, en general, ha evaluado el conocimiento nutricional moderado. Sin embargo, hubo correlación significativa entre la puntuación del cuestionario con el índice de masa corporal (r = - 0,38), perímetro de la cintura (r = - 0,30) y nivel educativo (r = 0,36). El conocimiento nutricional puede estar asociada con el estado nutricional y educativo.

Conhecimento nutricional e sua associação com o índice de massa corporal / Nutritional knowledge and its association with the body mass index

The number of individuals with excess body weight has been growingalarmingly in recent times, a fact attributed, in part, to changes in the quality of the diet consumed. The nutritional knowledge has been suggested by some researches to be able to directly infl uence food selection, and possibly may be associated with nutritional status. So, the objective of this study was to evaluate the association of nutritional knowledge level with Body Mass Index and levelof education. The sample consisted of 42 male (n=9) and female (n=33)individuals, aged 24-59 years, who were receiving nutritional monitoring ina rehabilitation center located in Sao Paulo city, Brazil. The anthropometricdata measured were body weight and height, and the Body Mass Index (bodyweight/height2) was calculated. The nutrition knowledge was measuredusing a previously validated questionnaire for the Brazilian population. It was possible to check that, generally, both groups showed moderate and low nutrition knowledge, and women had a signifi cantly higher score than men (p<0.05). However, no signifi cant correlation between the questionnaire score and the Body Mass Index were observed (r=0.16), while the latter was positively correlated with the degree of education (r=0.31, p<0.05). The results suggest that the nutritional knowledge does not seem to be determinant in food selection, and highlights the importance of nutrition strategies aimed to incorporating nutritional knowledge in promoting healthy habits.

El número de personas con exceso de peso corporal ha crecido de manera alarmante enlos últimos tiempos, un hecho atribuido, en parte, a los cambios en la calidad de la dieta consumida. El conocimiento nutricional de la población ha sido propuesto por algunos sondeos como un indicador capaz de influirdirectamente en la selección de alimentos por las personas, refl ejándose probablemente en su estadonutricional. El objetivo de este estudio fue evaluar la asociación entre el nivel de conocimiento nutricional, el Índice de Masa Corporal y la escolaridad. La muestra para este trabajo estuvocompuesta de 42 personas, nueve hombres y 33 mujeres, con edades comprendidas entre 24 y 59 años, que efectuaban acompañamientonutricional en un centro de rehabilitaciónubicado en São Paulo, Brasil. Los datosantropométricos medidos fueron peso y altura, calculándose el Índice de Masa Corporal (peso corporal/altura2). El conocimiento nutricional fue evaluado utilizando un cuestionario previamente validado para la poblaciónbrasileña. En general, es posible observar que ambos grupos mostraron conocimiento nutricional entre bajo y moderado, las mujeres con una puntuación significativamentemayor que los hombres (p<0,05). Sin embargo, no hay correlación significativa entre la puntuación en el cuestionario y el Índice de Masa Corporal (r=0,16), mientras el cuestionario se correlacionó positivamente con el grado deeducación (r=0,31, p<0,05). Los resultados sugieren que el conocimiento de nutrición no parece ser determinante para la selección de alimentos, resaltando que la incorporación deeste conocimiento es una estrategia nutricional importante en la promoción de hábitos saludables.

O número de indivíduos com excesso de peso corporal vem crescendo de maneira preocupante nos últimos tempos, fato este atribuído, emparte, pelas mudanças na qualidade da dieta consumida. O conhecimento nutricional vem sendo proposto por algumas pesquisas como umindicador capaz de influenciar diretamente a seleção alimentar e, possivelmente, se associarcom o estado nutricional. Dessa forma, o objetivo do presente estudo foi avaliar a associação do nível de conhecimento nutricional com o Índice de Massa Corporal e escolaridade. A amostra foicomposta por 42 indivíduos do gênero masculino (n=9) e feminino (n=33), com idade entre 24 e 59 anos, que realizavam acompanhamento nutricional em um centro de reabilitaçãolocalizado no município de São Paulo, Brasil. Os dados antropométricos mensurados foram peso corporal, estatura e calculado o Índice de Massa Corporal (peso corporal/estatura2).O conhecimento nutricional foi mensurado por meio de um questionário previamente validado para a população brasileira. Foi possível observar que, de modo geral, ambos os grupos apresentaram conhecimento nutricional baixo e moderado, sendo mulheres com a pontuação significativamente maior que homens (p<0,05).Porém, não houve correlação significativa entre a pontuação obtida no questionário com o Índice de Massa Corporal (r=0,16), enquantoque essa foi positivamente correlacionada com o grau de escolaridade (r=0,31; p<0,05). Osresultados obtidos sugerem que o conhecimento nutricional pareça não ser determinante na seleção alimentar, destacando-se assim aimportância de estratégias nutricionais que visem à incorporação do conhecimento em nutrição na promoção de hábitos saudáveis.
