ABSTRACT

Introduction: The increased number of articles published in nutrition is a reflection of the relevance to scientific community. The characteristics and quality of nutritional studies determine whether readers can obtain valid conclusions from them, as well as their usefulness for evidence-based strategic policies. Objective: To determine the characteristics of papers published in nutrition journals. Method: Descriptive study design. We reviewed 330 original papers published between January-June 2007. From: American Journal of Clinical Nutrition (AJCN), Journal of Nutrition, European Journal Nutrition, European Journal of Clinical Nutrition and Public Health Nutrition. We classified them according to the subjects studied; risk factors, study design and country of origin. Results: Almost half the papers studied healthy people(53.3%). The most frequent illness was obesity (13.9%).Food consumption is the most frequent risk factor (63.3%).Social factors appear exclusively only in 3.6% of the papers. Clinical trials were the most common analytical design (31.8%), mainly in the AJCN (45.6%). Cross-sectional studies were the most frequent type of observational design (37.9%). Ten countries produced over half of the papers (51.3%). The US publishes the highest number of papers (20.6%), whilst developing countries make only scarce contributions to scientific literature on nutrition. Conclusions: Most of the papers had inferential power. They generally studied both healthy and sick subjects, coinciding with the aims of international scientific policies. However, the topics covered reflect a clear bias, prioritizing problems pertaining to developed countries. Social determinants of health should also be considered, along with behavioral and biological risk factors (AU)


Introducción: El crecimiento de la producción científica nutricional indica relevancia para la comunidad científica. Las características y calidad de los estudios determinan si sus lectores pueden obtener conclusiones válidas, y su utilidad en la orientación de estrategias políticas basadas en la evidencia. Objetivo: Determinar las características de las publicaciones en revistas de nutrición. Método: Estudio descriptivo. Se revisaron 330 artículos originales publicados entre enero-junio de 2007 en las revistas: American-Journal of Clinical-Nutrition (AJCN), Journalof Nutrition, European-Journal Nutrition, European-Journal of Clinical-Nutrition y Public-Health-Nutrition. Los artículos se clasificaron según los temas estudiados, factores de riesgo, diseño del estudio y país de origen. Resultados: Las personas saludables representan la mitad (53,3%) de la población estudiada. La obesidad fue la enfermedad más frecuente (13,9%). El consumo de alimentos fue el factor de riesgo más frecuente (63,3%). Un 3,6% de artículos consideraron factores sociales. Los ensayos-clínicos fueron los estudios analíticos más comunes(31,8%), principalmente en AJCN (45,6%). Los estudios-transversales más frecuentes fueron observacionales(37,9%). Diez países producen más de la mitad de los artículos(51,3%). Los EEUU publican el mayor número de artículos (20,6%); siendo escasa la contribución de los países en desarrollo. Conclusiones: La mayoría de los artículos presentan poder inferencial. La población estudiada se distribuye entre sana y enferma, coincidiendo con los objetivos de las políticas científicas internacionales. Sin embargo, los temas tratados reflejan un sesgo, dando prioridad a los problemas relativos a países desarrollados. Deberían considerarse determinantes sociales de la salud, junto con factores de riesgo de comportamiento y biológicos (AU)

ABSTRACT

Objetivo: El objetivo del presente estudio es valorar en que medida la cirugía mayor ambulatoria (CMA) y de corta estancia mantienen, aumentan o disminuyen las desigualdades por sexo en la asistencia sanitaria de las intervenciones quirúrgicas practicadas por hernia inguinocrural (HIC). Material y métodos: Estudio transversal sobre 3.834 reparaciones(3.076 hombres/758 mujeres) de HIC practicadas en el Hospital General Universitario de Alicante entre 1995 y 2004.Fuente: conjunto mínimo básico de datos (CMBD). Variables: edad, sexo, diagnóstico principal, procedimiento quirúrgico, fechas de intervención y de alta. Cálculo de frecuencias y tasas por sexo, edad y tipo de admisión: contraste de proporciones. Estancia media (EM) mediante Contraste Mann-Whitney. Resultados: El 78% de las HIC fueron operadas en régimen de CMA o corta estancia, el resto con estancia de tres días o mayor. El 50% de todas las reparaciones se practicaron en niños menores de 14 años, siendo la indicación de CMA mayor en las niñas. A los pacientes mayores de 55 años se les tiende a admitir menos en CMA, con mayor proporción de mujeres. RatioH/M de todas las HIC = 4,06. En CMA: 0-14 ratioH/M= 3,25; > 55 años ratio H/M = 6,87 (p < 0,001). En hospitalización convencional: > 55 ratioH/M = 3,65.EM total: > 55 = 3,66H y 4,09M (p < 0,001); EM CMA: > 55= 1,04H y 1,27M (p < 0,001). Conclusiones: La CMA representa la forma idónea de tratamiento quirúrgico para la HIC no complicada tanto en hombres como en mujeres, sobretodo en la infancia, adolescencia, jóvenes y adultos. La atención de las HIC en mayores de 55 años presenta sesgo de género: a las mujeres se las ingresa 3 días o más en mayor proporción que a los hombres, con menor EM, mientras que siendo casi 7 veces menor el número de casos de mujeres que de hombres en CMA, estas presentan mayor EM. Resulta pues una diferente atención médica por sexo para igual proceso patológico y edad. (AU)


Objective: This study is intended to evaluate in what way ambulatory and short stay surgery maintain, increase or reduce sexinequities on inguinal and femoral hernia (I&FH) repair. Method: Transversal study on 3834 I&FH operations (3076men/ 758 women) between 1995 and 2004. Source: hospital’s minimal basic data set. Variables: age, sex, main diagnosis, surgical procedure, operation and discharge dates. Frequency andrates of hernia procedures by sex, age and admission type: proportion contrast. Length of stay (LOS): Mann-Whitney contrast. Results: 78% of I&FH were operated on an ambulatory or short stay basis (AMB) vs. 22% that stayed in hospital 3 or more days (STAY). 50% of all repairs were done on children 0 to 14 years old, the indication for AMB was higher in girls. In the group of patients older than 55, rate of AMB is lower than in younger patients, being higher in women than in men. RatioM/W for allI&FH = 4.06. In AMB: ratio M/W for 0-14 = 3.25; ratioM/W for> 55 = 6.87 (p < 0.001). In STAY: ratioM/W for > 55 = 3.65.LOS in > 55 (AMB and Stay): 3.66 M 4.09W (p < 0,001).LOS for AMB in > 55: 1.04 M 1.27W (p < 0,001).Conclusions: AMB is the most suitable way for repairing uncomplicated I&FH in men as well as in women, and even more so for children, adolescents, young people and adults. Nevertheless, gender bias in patients older than 55 is revealed: a greater proportion of women are admitted for 3 or more days as compared to men. However LOS is shorter in women. On the other hand, the amount of women treated as AMB is seven times smaller than men, being LOS longer for women in this group. That shows a difference in medical attention depending on sex for the same pathological process and age (AU)
