Evaluación del estado nutricional en la detección de factores de riesgo cardiovascular en una población adulta

Revista Latinoamericana de Hipertension (Impact Factor: 0.04). 01/2011; 6(1):8-13.

ABSTRACT

Objective: To validate a nutritional assessment methodology to detect cardiovascular disease predisposing factors. Methods: It was applied a nutritional assessment, including the anthropometric indicators, and quantitative and qualitative measurement of food consumption. 50 volunteers, among 18 and 75 years, patient of the Endocrinology department database of the Hospital Militar "Dr. Carlos Arvelo" were evaluated. Results: According to anthropometric indicators, 66% of the patients show a BMI>25; 80% of them was above the reference values for waist circumference; 78% have a abdominal obesity for waist-hip ratio, and 60% with a body fat percentage higher to those normal values. When evaluating the food consumption, it was found: low-calorie diet (76%), high protein (52%), and high fat with a predominance of animal fat consumption (44%), hipoglucidic (80%) and low in dietary fiber (68%), all of these data is in according to reference values for the INN. These results are allowing the identification of cardiovascular risk factors, anthropometrical and diet. Conclusion: It can be concluded that the nutritional status through anthropometric and dietary indicators can be a useful tool in identifying risk factors for cardiovascular disease. It is imperative that the measurement and evaluation of the indicators should be performed in a larger sample of subjects in order to verify the consistency of the results

    ABSTRACT: The Glycemic Index (GI) and Glycemic Load (GL) are valid indicators of effect of foods on blood glucose response. This study aimed to assess the GI and GL of diets consumed by diabetics and nondiabetics adults, as indicators of diet quality and its relation to nutritional status. The study was carried out in the consultation of Endocrinology of the Military Hospital "Dr. Carlos Arvelo" during the period July 2010 - January 2011. This is a descriptive research, with a study group of 43 adult subjects, 23 diabetics (D) and 20 nondiabetics (ND). Nutritional anthropometric evaluation was applied and determined the GI and GL of diet. For comparison between means groups the test "t" of Student was conducted and for distributions between groups Chi2 was used. Was found a predominance of medium and high IG (70% ND and 88% in D), medium and high CG (75% in ND and 78.3% in D) and excess malnutrition (55% in ND and 70% D) in both groups. We conclude that GI and GL are alternative and valid indicators of quality of diet and may be considered useful in the assessment and dietary management of diabetics and in prevention of chronic diseases programs, aimed at the general population, without using isolated and unaware of their limitations.

    ABSTRACT: El Índice Glicémico (IG) y la Carga Glucémica (CG) son indicadores válidos del efecto de los alimentos en la respuesta de la glucosa plasmática. El objetivo de la investigación fue evaluar el IG y CG de las dietas consumidas por adultos diabéticos y no diabéticos, como indicadores de la calidad de la dieta y su relación con el estado nutricional. El estudio se llevó a cabo en la consulta de Endocrinología del Hospital Militar “Dr. Carlos Arvelo” durante el período julio 2010 – enero 2011. Se trata de una investigación descriptiva, con un grupo de estudio de 43 sujetos adultos, 23 diabéticos (D) y 20 no diabéticos (ND). Se aplicó una evaluación nutricional antropométrica y se determinó el IG y CG de la dieta. Para la comparación entre las medias de los grupos se realizó la prueba de “t” de Student y para las distribuciones entre los grupo se utilizó Chi2. Se encontró un predominio de IG medio y alto (70% en ND y 88% en D), CG moderada y alta (75% en ND y 78% en D) y malnutrición por exceso (55% en ND y 70% en D) en ambos grupos. Se concluye que IG y CG son indicadores alternativos y válidos de la calidad de la dieta y puede considerarse su utilidad en la evaluación y manejo dietoterapéutico de los diabéticos y en programas de prevención de enfermedades crónicas, dirigidos a la población en general, sin hacer uso aislado ni desconocer sus limitaciones.

    ABSTRACT: Introduction: The instruments to estimate consumed portion are a key factor, which ensures data quality in surveys of food intake assessment. Venezuela does not have a tool like this, properly validated and published. The aim of the study was develop a photographic atlas as a complementary tool for assess usual food consumption in Venezuelan adults. Material and Methods: Foods were classified into 13 groups according to their similarity in nutrient content according to the table of composition and the food balance sheet of Venezuela. We selected the most consumed by Venezuelans according to data from national studies and another researches by the authors. For each food were set 3 portion sizes: small, medium and large; which were weighed in an electronic balance before taking a picture. Later, the atlas underwent a valuation process by experts. Results: The instrument includes 110 foods with a total of 300 photographs, distributed in 100 sheets, presenting the advantages of quality control used during the planning and design, the review of national and international reference materials. The experts successfully assessed the pertinence of the items and the relevance of the atlas information. Conclusions: The photographic atlas of foods developed, in the opinion of the expert reviewers, could be a useful tool to be used in the evaluation of food consumption in Venezuelan adults. However, to fulfill this purpose, the proposed instrument should be validated to prove their technical conditions of validity and reliability.

Questions & Answers about this publication

  • Pablo Ignacio Hernandez Rivas added an answer in Sport Nutrition:
    Do anyone know a reference about the women usually under-reported when answer dietary records?

    Some time ago I read in a sport paper (probably Volek JS, but I do not remember) which said that women habitually under-reported when answer different dietary records.

    I work with female athletes and always when I calculate their nutritional intake, with 7- days records or validated food frequency questionnaire, see low energy intake and macronutrients, specially carbohydrates.

    I think a possible justification, they do not write every food which eat.

    You are not alone! In our experience, is very commonly found diets low in carbs and low in calories. But very high in proteins. In women and men with R-24h.

    Culturally, in our population the carbs are bad, more if the person have diabetes. So, we need more investigation in this topic.
