La actividad física y el estado nutricional y psicosocial del anciano no dependiente / Physical activity and nutritional and psychosocial status in non-dependent elderly

OBJETIVO: Describir el grado de actividad física (AF) de una muestra de ancianos independientes no institucionalizados y la relación entre aquel y el estado nutricional y las condiciones psicosociales de los ancianos. MATERIAL Y MÉTODOS: Estudio descriptivo transversal multicéntrico implementado en los centros de salud urbanos de la ciudad de Huesca en mayores de 75 años. Tamaño muestral 60 pacientes. Se analizaron variables demográficas, psicosociales, nutricionales, antropométricas y AF. Para la medición de esta última, se utilizó la escala breve de Minnesota en español (VREM). RESULTADOS: La edad media fue de 81,58 años (±4) con una distribución por género del 51,7% mujeres. El grupo mostró globalmente una situación de salud favorable: Afectación física leve (45%), correcta salud mental referida al estado cognitivo (93%) o de ánimo (88%), estado social favorable (96%), independencia para las actividades de la vida diaria (100%) y buena calidad de vida percibida (puntuación>70 en el 70%). En relación con la AF se obtuvo una media de 4666,2MET-min/14 días y se identificaron como sedentarios el 10% de los participantes. Se obtuvo una relación inversa estadísticamente significativa de la AF con la incapacidad funcional, la sarcopenia y la composición corporal (perímetro de cintura, diámetro abdominal sagital, índice de masa y porcentaje de grasa corporales) (p < 0,05). La AF no mostró relación significativa con el estado nutricional y las condiciones psicosociales. Sí resultó significativa la observada entre el estado nutricional y las variables de la esfera psicosocial (p < 0,01). CONCLUSIONES: Las características de la población estudiada en las esferas orgánica, funcional, psíquica y social no sugieren importantes limitaciones para la AF. Un porcentaje nada despreciable de ancianos no realiza suficiente AF. Existe una relación significativa entre la realización de ejercicio físico y los índices de composición corporal favorables

OBJECTIVE: To describe the level of physical activity (PA) of a sample of independent non-institutionalised elderly and its relationship between nutritional status and psychosocial conditions of the elderly. MATERIAL AND METHODS: A multicentre cross-sectional descriptive study carried out in Health Centres of the city of Huesca in a sample size of patients over 75 years-old. Demographic, psychosocial, nutritional, anthropometric, and PA variables were analysed. The short scale of Minnesota in Spanish (VREM) was used to measure the latter. RESULTS: The mean age was 81.58 years (±4) with a gender distribution of 51.7% women. The group were in a good health condition overall: Mild physical impairment (45%), correct mental health as regards cognition (93%) or mood (88%), favourable social status (96%), independence for activities of daily living (100%), and a good perceived quality of life (score>70 in 70%). There was a mean of 4666.2 METS-Min/14 days obtained in PA, and 10% of the participants were identified as sedentary. A statistically significant inverse relationship (P<.05) was observed between PA and functional disability, sarcopenia and body composition (waist circumference, sagittal abdominal diameter, mass index, and body fat percentage). No significant relationship was observed between PA and nutritional status and psychosocial conditions. The relationship between the nutritional status and the variables of the psychosocial sphere was significant (P<.01). CONCLUSIONS: The characteristics of the population studied in the organic, functional, psychical, and social spheres do not suggest important limitations for PA. An insignificant percentage of the elderly does not perform enough PA. There is a significant relationship between physical exercise and favourable body composition rates

Influencia de la etnia y el sexo en la ingesta de alimentos como factores de riesgo de malnutrición en escolares / Influence of ethnicity and gender in school children food intake as malnutrition risk factors

La dieta de los niños en nuestro país suele ser deficitaria en frutas y verduras y rica en alimentos hipercalóricos. El objetivo del presente estudio es valorar la frecuencia de la ingesta de los grupos de alimentos en escolares de nuestro medio y la influencia sobre ella del sexo y la etnicidad. Se valoraron en una población de 383 niños de 2.º, 3.º y 4.º de Educación Primaria las características socioeconómicas y demográficas, los estilos de vida y la frecuencia de ingesta de grupos de alimentos. Los niños ingirieron más raciones diarias de alimentos ricos en hidratos de carbono (4,38 ± 1,6 frente a 3,97 ± 1,4; p=0,03) y más lácteos (3,23 ± 1,1 frente a 2,83 ± 1,0; p= 0,002) que las niñas; por otro lado, la niñas consumieron más golosinas que los niños (2,81 ± 3,9 frente a 2,01 ± 2,3 raciones por semana; p= 0,03). Un alto porcentaje de niños no cumplía con las recomendaciones habituales de ingesta por defecto de frutas y verduras (78,1%), lácteos (43,4%) e hidratos de carbono (42,8%), y por exceso de proteicos (8,1%), bollería (21,2%),golosinas (18,9%) y refrescos-snacks (8,7%). Los niños pertenecientes al grupo con etnicidad ingirieron significativamente menos lácteos, alimentos proteicos y fruta-verdura y, sin embargo, más bollería, golosinas y refrescos-snacks que los niños sin etnicidad. En el análisis de la relación entre los distintos grupos de alimentos se han encontrado dos asociaciones significativas (p <0,01): 1) la ingesta de frutas y verduras se asoció a un mayor consumo de hidratos de carbono y de pescado, y aun menor consumo de refrescos-snacks y tiempo frente al televisor; 2) la ingesta de bollería se asoció a un mayor consumo de refrescos/snacks y de golosinas. El estudio concluye que el sexo y la etnicidad son factores que influyen en la dieta de los niños en edad escolar y deben considerarse como factores de riesgo de malnutrición (AU)

Children’s diet in our country seems to be deficient in fruits and vegetables and rich in hyper caloric food. The purpose of this study is to access intake frequency of food groups in school children of our environment and the influence gender and ethnicity pose over it as well. We have evaluated the socioeconomic and demographic characteristics, lifestyles and the intake frequency of food groups in a population of 383 2nd, 3rd and 4th grade children from elementary school. Boys consume more daily servings of food rich in carbohydrates (4.38 ± 1.6 vs. 3.97 ± 1.4; p=0.03) and more dairy products (3.23 ± 1.1 vs. 2.83 ± 1.0; p= 0.002) than girls, and, on the other hand, girls eat more candy than boys (2.81 ± 3.9 vs. 2.01 ± 2.3 servings per week; p= 0.03). A high percentage of children did not meet regular recommended food percentages, both by deficiency: fruits and vegetables (78.1%), dairy products (43.4%) and carbohydrates (42.8%); and by excess: protein food (8.1%), pastries (21.2%), candy (18.9%), and sodas/snacks (8.7%). Children belonging to a certain ethnic group consume significantly less dairy products, protein products and fruits/vegetables; and, at the same time, more pastries, candy and sodas/snacks than children that do not belong to a specific ethnic group. Two significant associations (p <0.01) have been found in the analysis of the relationship between different food groups: 1) fruits and vegetables intake was associated with a higher consumption of carbohydrates and fish, and with alower consumption of sodas/snacks and time watching TV; and2) pastry intake was associated with a higher consumption of sodas/snacks and sweets. The study concludes that gender and ethnicity are factors that influence the school children´s diet and they shall be considered as risk factors for malnutrition (AU)

[The degree of agreement in the radiological interpretation of the growth of left cardiac cavities between the radiologist, the family physician and residents in family and community medicine]. / Grado de acuerdo en la interpretación radiológica de crecimiento de cavidades cardíacas izquierdas entre radiólogo, médico de familia y residentes de MFYC.

OBJECTIVE: To discover the level of agreement about the radiological interpretation of the growth of left-side cardiac cavities, between the referring radiologist (Rx), a family doctor (FD) and three interns studying the third year of family and community medicine (IFCM). DESIGN: Observational crossover study. SETTING: Primary Care (PC). The Perpetuo Socorro Health Centre in Huesca. PATIENTS AND OTHER PARTICIPANTS: Hypertense patients included in the programme of one of the general medicine sections. MEASUREMENTS AND MAIN RESULTS: There were 69 thorax radiographies (TXR), 10 of which were repeated in order to assess the level of agreement between different evaluations by the same observer (intra-observer). Out of these 69, there was agreement between observers in 39 cases (66.10%) with Kappa Index (KI) 0.39 +/- 0.12 for two IFCMs (2 and 3); in 44 (74.57%), with KI 0.55 +/- 0.12 for the first IFCM; and in 40 (67.10%), with KI 0.39 +/- 0.12 for the FD. The intra-observer agreement was 80% with KI 0.50 +/- 0.29, 60% with KI 0.20 +/- 0.23 and 90% with KI 0.80 +/- 0.23 for the three IFCM's. It was 70% with KI 0.34 +/- 0.27 for the FD and 80% with KI 0.48 +/- 0.29 for the Rx. CONCLUSIONS: Both the inter- and intra-observer agreement levels were insufficient. We propose that our training during the period of specialisation should be strengthened on the most useful questions from the PC point of view. Studies of this sort need to be carried out in PC in order to obtain maximum benefit from these complementary tests.
