[Health impact of the community intervention programme "Health education in adolescence"]. / Impacto en la salud del programa de intervención comunitaria «Educación para la salud en la adolescencia¼.

OBJECTIVE: To measure the impact of the community health programme "Education for health in adolescence" carried out in the Parquesol neighborhood, Valladolid (Spain), during the years 2015-2019. METHOD: Community-based quasi-experimental pre- and post-test analytical intervention trial with control group. A total of 407 adolescent surveys were collected. The CHIP-AE test validated for Spain was used. Pre- and post-test results were analyzed and compared with the control group. RESULTS: Improvements were found in the female intervention group compared to the control group in the variables resilience (3.68 vs. 3.41; p <0.01), health and safety at home (4.30 vs. 4.00; p <0.01), physical activities (3.16 vs. 2.60; p <0.01) and self-esteem (3.17 vs. 2.79; p <0.05). CONCLUSIONS: The community intervention carried out improves the health profile of adolescents. The baseline perception of health presents differences by gender, with higher scores in males. Post-intervention improvement is substantial in females in resilience, physical activities and health and safety at home. In addition, the worsening due to the passage of time described in previous studies is corrected in the variables self-esteem, satisfaction and well-being.

Pelvic Venous Congestion Secondary to a Circumaortic Renal Collar in an Adolescent Female: Report of a Case.

We report a 13-year-old girl who presented with a recurrent abdominal pain that started after her menarche. The abdominal palpation revealed tenderness over the left ovarian point. The laboratory study, ultrasonography, and abdominal X-ray were normal. The computed tomography and magnetic resonance imaging showed a double left renal vein with a retroaortic component, an increased left parauterine circulation, and ipsilateral ovarian vein engorgement. A diagnostic and therapeutic phlebography allowed a selective catheterization of a group of pelvic varicose veins draining to the left ovarian and to the internal iliac veins. There were no complications during the procedure and the symptoms disappeared 2 days later. Circumaortic left renal vein may cause hematuria, proteinuria, pelvic congestion syndrome, and massive hemorrhage during surgery. A conservative treatment is recommended for patients without gynecourological/renal symptoms or with mild hematuria. The endovascular treatment by gonadal venous embolization is safe and effective.

Bioelectrical impedance vector analysis in obese and overweight children.

INTRODUCTION: BMI is the most commonly used indicator to evaluate overweight and obesity, but it cannot distinguish changes in body composition. Over recent years, it has been demonstrated that bioelectrical impedance analysis (BIA) is a more accurate method for analyzing body composition. Bioelectrical impedance vector analysis (BIVA) has revealed its effectiveness as an indicator of nutritional status and hydration. OBJECTIVE: To assess the usefulness of bioimpedance analysis on the study of body composition in a group of children with overweight and obesity. MATERIALS AND METHODS: Cross-sectional observational study. The anthropometric parameters of 167 (79 were older than 12 years) overweight and obese children were recorded. Their body composition was analyzed using BIA and BIVA, and was classified based on different criteria. Concordance was analyzed (intraclass correlation coefficient, Bland-Altman analysis and weighted Kappa coefficient). The BIVA of the subgroups was compared using the Mahalanobis distance and Hotelling's T2. Statistical significance was considered for p<0.05. RESULTS: The BMI revealed that the majority of the assessed subjects were obese, although 12% had a normal percentage of fat mass (%FM). The classification by Z-BMI and Z-%FM significantly discriminate between subjects with different levels of adiposity. In children over the age of 12, the classification of fat mass index also discriminates significantly between obesity and non-obesity. As anticipated, in the tolerance ellipses, most of the individual vectors were situated in the left lower quadrant. CONCLUSIONS: BIVA reflects differences in the bioelectric patterns of children who are classified as being overweight or obese (BMI) and who have different levels of %FM and FMI. BIVA permits a fast and easy monitoring of the evolution of the nutritional state and changes associated with body composition, and it identifies those children whose body compartments may be precisely estimated using traditional BIA methods.

Zinc Nutritional Status in Patients with Cystic Fibrosis.

BACKGROUND: Zinc is an essential nutrient for all forms of life and its deficiency affects the normal growth and development of human beings. OBJECTIVE: The main aim was to investigate zinc nutritional status by serum zinc concentration (SZC) and dietary zinc intake and their association in cystic fibrosis (CF) patients. METHODS: A cross-sectional study was conducted in CF patients. Anthropometric measurements and respiratory and pancreatic tests were conducted. Hypozincemia was determined by SZC while using atomic absorption spectrophotometry and dietary zinc deficiency by prospective 72-h dietary surveys. RESULTS: Mean SZC (87.2 ± 16.7 µg/dL) and dietary zinc intake (97 ± 26.9% Dietary Reference Intake) were normal. Three of 17 patients with CF (17.6%) had hypozincemia and four (23.5%) had a dietary zinc deficiency. No patient with dietary zinc deficiency had hypozincemia. A positive and significant association was observed between SZC and Z-score of BMI-for-age (p = 0.048) and weight-for-height (p = 0.012) and between dietary zinc intake and energy intake (EI, p = 0.036) and Z-score of weight-for-high (p = 0.029). CONCLUSION: SZC was associated with the nutritional status, expressed as BMI (Body Mass Index) and weight-for-height Z score, and dietary zinc intake with EI and weight-for-height Z-score. No patient with hypozincemia had dietary zinc deficiency. This situation should alert us to a marginal zinc deficiency and it may explain why there were no overlapping cases between the two groups. We suggest that probably 41% of the cases in this study would be at elevated risk of zinc deficiency and a zinc supplementation may be considered.

[Excess weight in patients with cystic fibrosis: is it always beneficial?]

INTRODUCTION: The primary objective of this study was to find out the prevalence of overweight and obese status, as well as their association to pulmonary function, total cholesterol and vitamin D in patients with cystic fibrosis (CF). MATERIALS AND METHODS: This is a multicenter descriptive and cross-sectional study. Twelve Spanish hospitals participated. 451 patients with CF were included. Adults were classified according to body mass index (BMI) and children were classified according to BMI percentiles (WHO tables). Pearson's correlation, Anova, Student's t-test and multiple linear regression were conducted. RESULTS: Mean age was 12.3 (range 4-57) years old, 51% were male and 18% had pancreatic sufficiency. Participants were classified in five nutritional status categories: 12% were malnourished; 57%, at nutritional risk; 24%, normally nourished; 6%, overweight; and 1%, obese. Pulmonary function in overweight or obese patients (91 ± 19%) was better than in malnourished patients (77 ± 24%) (p = 0.017). However, no difference was observed between those at nutritional risk (86 ± 19%) or normally nourished (90 ± 22%) groups. Overweight and obese patients had higher levels of total cholesterol (p = 0.0049), a greater proportion of hypercholesterolemia (p = 0.001), as well as lower levels of 25 OH vitamin D (p = 0.058). CONCLUSIONS: Prevalence of overweight and obese was 6 and 1%. Excess weight status does not offer any benefit in pulmonary function in comparison to normally nourished patients.

Ingesta dietética y adherencia a la dieta mediterránea en un grupo de estudiantes universitarios en función de la práctica deportiva.

Introducción: la alimentación de los jóvenes universitarios se aleja cada vez más de la dieta mediterránea (DM). El binomio alimentación-actividad física es fundamental para mantener un adecuado estado de salud.Objetivo: comparar la ingesta en un grupo de estudiantes universitarios deportistas frente a otro que no realiza deporte habitualmente.Sujetos y métodos:estudio observacional transversal realizado en 49 voluntarios de la Universidad de Valladolid. Se determinaron peso, talla y actividad física (cuestionario GPAQ). La ingesta se evaluó a partir de un cuestionario de frecuencia de consumo y un registro de alimentos de 3 días. La adherencia a la DM se estimó con el Mediterranean Diet Score. Las diferencias entre las variables en función del sexo y la práctica deportiva se analizaron con la t de Student o la U-Mann-Whitney. Significación estadística: p < 0,05.Resultados: todos los sujetos presentaron normopeso, sin diferencias en función de la práctica deportiva. El nivel de actividad física fue inferior en las mujeres. En todos los estudiantes la dieta fue ligeramente hiperproteica, rica en grasas y colesterol, con un inadecuado perfil lipídico y deficiente en hidratos de carbono y fibra. Se cubren los requerimientos de micronutrientes. Destaca un escaso consumo de frutas-verdurashortalizas, cereales, aceite de oliva, pescado y frutos secos; y un exceso de carne, mantequilla, bollería-industrial, dulces, snacksy refrescos. El 50% de la muestra tiene una adherencia baja o muy baja a la DM.Conclusión: las dietas de los jóvenes universitarios no cumplen los objetivos nutricionales para la población española y presentan una adherencia media-baja a la DM, independientemente de la práctica deportiva.

[Not Available]. / Nutritional approach of inpatients with anorexia nervosa.

Anorexia nervosa (AN) is the most prevalent of eating disorders in children and adolescents, and its treatment is long and complex, involving a multidisciplinary team. Nutritional rehabilitation and restoration of a healthy body weight is one of the central goals in the initial stages of inpatient treatment. However, current recommendations on initial energy requirements for these patients are inconsistent, with a clear lack of controlled studies, available scientific evidence and global consensus on the most effective and safe refeeding practices in hospitalized adolescents with anorexia nervosa (AN). Conservative refeeding recommendations have been classically established in order to prevent the refeeding syndrome. Nevertheless, various works have recently appeared advocating a higher initial caloric intake, without observing more complications or refeeding syndrome, and allowing a shorter average stay. We present our experience in the treatment of restricting AN with a conservative progressive treatment. We have obtained good results with this approach, which was well tolerated by patients, with no observing complications. As a consequence, the medical team could establish a pact about the therapeutic goals with the patients in an easier way.

[VITAMIN D AND CHRONIC LUNG COLONIZATION IN PEDIATRIC AND YOUNG ADULTS CYSTIC FIBROSIS PATIENTS]. / VITAMINA D Y COLONIZACIONES PULMONARES CRÓNICAS EN PACIENTES PEDIÁTRICOS Y ADULTOS JÓVENES CON FIBROSIS QUÍSTICA.

INTRODUCTION AND OBJECTIVES: evaluate vitamin D status and its association with chronic lung colonisation in Cystic Fibrosis patients. MATERIAL AND METHODS: descriptive cross-sectional multicenter study. From November 2012 to April 2014, at 12 national hospitals, 377 patients with Cystic Fibrosis were included. Vitamin D levels < 30 ng/ml were classified as insufficient. Chronic colonisation was considered if they had at least two positive cultures in the past year. RESULTS: the median age was 8.9 years (2 months to 20 years). 65% had insufficient levels of vitamin D. There was an inverse correlation between age and vitamin D levels (r = -0.20 p < 0.001). Those diagnosed by screening, were younger and had higher levels of vitamin D. There was an inverse correlation between the number of colonisations and vitamin D levels (r = -0.16 p = 0.0015). Adjusting for age, pancreatic status and diagnosis by screening, colonization by S. aureus in 6 years, increased the risk of insufficient levels of vitamin D: OR 3.17 (95% CI 1.32 to 7.61) (p = 0.010) and OR 3.77 (95% CI 1.37 to 10 , 37) (p = 0.010), respectively. CONCLUSIONS: despite adequate supplementation, more than half of our patients did not achieve optimal levels of vitamin D. Regardless of age, diagnosis by screening or pancreatic status, chronic colonization by Pseudomonas sp. in children and adolescents and S. Aureus in infants and preschoolars increases the risk of developing vitamin D deficiency in these patients.

Introducción y objetivos: conocer la situación en la que se encuentran los pacientes con fibrosis quística en relación con sus niveles de vitamina D y su asociación con las colonizaciones pulmonares crónicas. Material y métodos: estudio multicéntrico transversal. Participaron 12 hospitales nacionales. De noviembre a abril del 2012 al 2014 se incluyeron 377 pacientes con fibrosis quística. Se consideraron insuficientes niveles de vitamina D < 30 ng/ml. Presentar al menos dos cultivos positivos en el último año fue considerado un criterio de colonización crónica. Resultados: los pacientes tenían una mediana de edad de 8,9 años (2 meses­20 años). Un 65% presentaban niveles insuficientes de vitamina D. Se observó una correlación inversa entre edad y niveles de vitamina D (r = -0,20 p < 0,001). Los diagnosticados por cribado eran más jóvenes y tenían niveles de vitamina D más altos. Los niveles de vitamina D presentaron una correlación inversa con el número de colonizaciones pulmonares (r = -0,16 p = 0,0015). Ajustando por edad, función pancreática y diagnóstico mediante cribado, la colonización por S. Aureus en menores de seis años y por Pseudomonas sp. en los mayores de esa edad, incrementaban el riesgo de presentar niveles insuficientes de vitamina D: OR 3,17 (IC95% 1,32-7,61) (p=0,010) y OR 3,77 (IC95% 1,37- 10,37)(p = 0,010), respectivamente. Conclusiones: a pesar de una suplementación adecuada, más de la mitad de nuestros pacientes no alcanzan niveles óptimos de vitamina D. La colonización crónica por Pseudomonas sp. en escolares y adolescentes y por S. Aureus en lactantes y preescolares se asocia de forma independiente con la deficiencia de vitamina D.

[Design and implementation of a questionnaire to evaluate the dietary quality of school meals]. / Diseño y aplicación de un cuestionario de calidad dietética de los menús escolares.

INTRODUCTION: The school canteen provides a substantial proportion of the daily nutritional intake for many children. There are nutritional standards for school meals, however, it is still difficult to assess the dietary quality. AIMS: To design a questionnaire for assessing the dietary quality of school meals, quickly and easily. METHODS: A dietary questionnaire (COMES) was designed on the basis of the current recommendations. COMES consist of 15 items related to the food-frequency and to other characteristics of school meals. Then, a longitudinal prospective study was performed in order to analyze, with COMES, 36 school meals of 4 catering companies from Castilla y León during the academic years 2006-2007 to 2010-2011. Differences in dietary quality menus according to the management system of catering companies (in situ vs. transported) were analyzed by using the Mann-Whitney and the Kruskal-Wallis tests. The significance was reached at p <0,05. RESULTS: The frequency intake of meat, dairy and prepared products was higher to the recommended in 97,2%, 94,4% and 27,8% of the analyzed menus, respectively. By contrast, the frequency intake of fish, fruit, legume, and vegetable garnishes were lower to the recommended in 83,3%, 94,4%, 91,7% and 75% of menus, respectively. Nevertheless, recommendations established by our consensus document for school meals are complied for all food groups, except for dairy and fruits. The variety of foods and culinary techniques were appropriate. No significant differences were found in the COMES score according to the management system (p=0,87), although catering system provides higher dietary quality. CONCLUSIONS: A new tool to assess quickly and easily the nutritional quality of school meals has been proposed. The assessment of the frequency intake of the most problematic foods for schoolchildren with this scale is much more demanding than the current recommendations. Even so, menus analyzed showed an acceptable quality in terms of variety of foods and culinary techniques, although milk frequency in the menus was excessive at the expense of fresh fruit. On the other hand, the transported system (i.e. catering, both hot and cold-holding) provides menus more consistent with the dietary recommendations.

Introducción: El comedor escolar es el centro de comida habitual para muchos niños. Aunque actualmente se dispone de guías y recomendaciones para los menús escolares, resulta difícil evaluar su calidad dietética. Objetivos: Diseñar un cuestionario para evaluar la calidad desde el punto de vista dietético de los menús escolares de forma rápida y sencilla. Material y métodos: Partiendo de las recomendaciones, se ha diseñado un cuestionario (COMES) de 15 ítems que hacen referencia a la frecuencia de consumo de alimentos y otras características de los menús escolares. A continuación se realizó un estudio longitudinal prospectivo en el que se analizaron con este cuestionario 36 planillas de menús de 4 empresas de restauración colectiva que prestaban el servicio de comedor escolar en Castilla y León durante los cursos 2006-2007 a 2010-2011. Se analizaron las diferencias en función del sistema de gestión de las empresas mediante la prueba U de Mann-Whitney y el test de Kruskal- Wallis. La significación se alcanzó con una p.
