RESUMO

Recent interest in protein intake per meal is observed in studies that have reported the protein intake patterns in different countries; however, comparisons of these data are lacking. We aimed to compare protein intake patterns and the percentage of inadequate protein intake (IPI) per day and meal in older adults from different countries. We acquired data of protein intake in older adults from four countries (Mexico, United States of America, Germany, and United Kingdom). We compared protein intake (per day and meal), IPI per day and meal, and the number of meals with an adequate protein content among countries. The IPI per day significantly differed among countries for <0.8 and <1.0 (both p < 0.001), but not for <1.2 g/kg/d (p = 0.135). IPI per meal (<30 g/meal) did not differ among countries at breakfast (p = 0.287) and lunch (p = 0.076) but did differ at dinner (p < 0.001). Conversely, IPI per meal (<0.4 g/kg/meal) significantly differed among countries at breakfast, lunch, and dinner (all p < 0.001). The percentage of participants that ate ≥30 g/meal or ≥0.4 g/kg/meal at zero, one, and two or three meals per day significantly differed among countries (all p < 0.05). IPI at breakfast and lunch (<30 g/meal) was a common trait in the analyzed samples and might represent an opportunity for nutritional interventions in older adults in different countries.

RESUMO

Background: The control of the birthrate and the decrease of the mortality have unleashed a demographic aging. Nutritional status indicators are useless and in some cases it is not possible to determine the exact height or weight, making these indicators useless. Aim: To correlate the BMI with calf perimeter and muscle strength (dynamo-metry dominant and non-dominant). Methods: We studied 60 adults over 60 years old, with self-maintenance functional capacity. The subjects belonged to the "Circle of Retired Chilean Police" of Chillan city in Chile. The anthropometric measurements and dynamometry were obtained according to WHO specifications. We used correlation coefficients and ANOVA to determine the association between variables. Results: There was a weak negative relationship between dynamometry with BMI, r= -0.19 dynamometry dominant (p=0.332) and r= -0.11 dynamometry non-dominant (p=0.806), but a positive correlation was found between the calf perimeter and BMI, r= 0,64 (p<0.001). Conclusions: The data show the utility of calf perimeter as an indicator of nutritional status in the study of subjects, which was not observed with dynamometry.

Introducción: El control de la natalidad y el descenso de la mortalidad han desencadenado un envejecimiento demográfico, por lo que en algunos casos no es posible determinar con exactitud la estatura o el peso, careciendo de utilidad los indicadores nutricionales. Objetivo: Relacionar el índice de masa corporal (IMC) con el perímetro de pantorrilla y la fuerza muscular medida por la dinamometría de mano dominante y no-dominante. Métodos: Se estudiaron 60 adultos mayores de 60 años, con capacidad funcional de autovalencia, los adultos pertenecían al círculo de Carabineros de Chile en retiro de la ciudad de Chillan en la VII Región. Los datos antropométricos y la dinamometría se determinaron de acuerdo a las técnicas establecidas por la OMS. Se utilizó el coeficiente de correlación y Anova para determinar la asociación entre las variables. Resultados: Se observó una relación negativa débil entre ambas dinamometrías con el IMC; r = -0.19, dominante (p 0.332) y no dominante r = -0.11 (p 0.806), pero se encontró una correlación positiva de carácter mediana, entre el perímetro de pantorrilla y el IMC, r = 0.64 (p<0.001). Conclusiones: Los datos aportados evidencian la utilidad del perímetro de pantorrilla como indicador del estado nutricional en los sujetos de estudio, no así la dinamometría de mano.

RESUMO

With the purpose of maiking easier the determination of the physiological age of Stomosys calcitrans population, a classification based on the oocitary developtment and number of ovipositions was proposed. Female were reared under laboratory conditions, in individual cages and maintained in the presence of male for copulation. On the proper time, ovary and oviduct were removed and the stage of development was observed. Adult female were classified as: 1-New emerged female, 2 - Young nuliparous female, 3 - Old nuliparous female, 4 - Uniparousfemale, 5 - Two or three ovipositions times female, and 6 - Multiparous female.
