          Abstract

          Objetivo Analizar el efecto del menú servido nutricionalmente balanceado, a empleados de Empresas Publicas de Medellín en los campamentos de generación de energía (Guadalupe, Guatapé-Playas y La Sierra), en el índice de masa corporal (IMC), porcentaje de grasa corporal, niveles de lípidos séricos, después de una intervención de cuatro meses, entre diciembre de 2009 y marzo de 2010. Métodos Estudio cuasi experimental de intervención a alimentación suministrada en cantidad y calidad a 129 empleados voluntarios, evaluando las variables antes y después, para establecer cambios. Resultados Después de la intervención los lípidos séricos se redujeron significativamente (p<0,001), específicamente colesterol total -13,3 ± 36,4 mg/dl (IC 95 % -214; 68) y triglicéridos -81,2 ± 138,1 mg/dl (IC 95 % -757; 81); el IMC bajó 0,13 ± 0,76 unidades (IC 95 % -0,3; 0,01) y el porcentaje de grasa corporal varió -0,31 ± 2,19 % (IC 95 %-0,69; 0,07), a pesar de ser reducciones no significativas (IMC: p=0,63 y % de Grasa: p=0,11) sí son biológicamente plausibles dada su relación con disminución de riesgos de salud. Conclusión Los servicios de alimentación a colectivos son lugares en los cuales se pueden realizar intervenciones nutricionales efectivas que favorezcan el estado de salud y nutrición de los usuarios atendidos, sin representar complicaciones en la producción.

          Objetive Analyzing the effect of a nutritionally-balanced menu served to Medellín public company employees (Guadalupe, Guatapé-Playas and La Sierra) on their body-mass index (BMI), percentage of body fat and serum lipid levels following a four-month intervention between December 2009 and March 2010. Methods This involved a quasi-experimental intervention regarding the food supplied to 129 volunteer employees in terms of quantity and quality; variation in variables was evaluated before and after the intervention. Results Serum lipid levels became significantly reduced following the intervention, (p<0.001), specifically total cholesterol (13.3 ± 36.4 mg/dl; -214-68 95 % CI) and triglycerides (-81.2 ± 138.1 mg/dl; -757-81 95 % CI). The BMI was down by 0.13 ± 0.76 units (-0.3- 0.01 95 % CI) and % body fat varied by -0.31 ± 2.19 % (-0.69-0.07 95 %Ci) despite these being statistically non-significant reductions (BMI: p=0.63; % fat: p=0.11); however, they were biologically plausible because of their relationship to reduced health hazards. Discussion Canteens are places where effective nutritional interventions can be made to promote their users' health and nutrition without representing service production complications.

            Statins, high-density lipoprotein cholesterol, and regression of coronary atherosclerosis.

            Statins reduce low-density lipoprotein cholesterol (LDL-C) levels and slow progression of coronary atherosclerosis. However, no data exist describing the relationship between statin-induced changes in high-density lipoprotein cholesterol (HDL-C) and disease progression. To investigate the relationship between changes in LDL-C and HDL-C levels and atheroma burden. Post-hoc analysis combining raw data from 4 prospective randomized trials (performed in the United States, North America, Europe, and Australia between 1999 and 2005), in which 1455 patients with angiographic coronary disease underwent serial intravascular ultrasonography while receiving statin treatment for 18 months or for 24 months. Ultrasound analysis was performed in the same core laboratory for all of the studies. Relationship between changes in lipoprotein levels and coronary artery atheroma volume. During statin therapy, mean (SD) LDL-C levels were reduced from 124.0 (38.3) mg/dL (3.2 [0.99] mmol/L) to 87.5 (28.8) mg/dL (2.3 [0.75] mmol/L) (a 23.5% decrease; P or =5% reduction in atheroma volume) was observed in patients with levels of LDL-C less than the mean (87.5 mg/dL) during treatment and percentage increases of HDL-C greater than the mean (7.5%; P<.001). No significant differences were found with regard to clinical events. Statin therapy is associated with regression of coronary atherosclerosis when LDL-C is substantially reduced and HDL-C is increased by more than 7.5%. These findings suggest that statin benefits are derived from both reductions in atherogenic lipoprotein levels and increases in HDL-C, although it remains to be determined whether the atherosclerotic regression associated with these changes in lipid levels will translate to meaningful reductions in clinical events and improved clinical outcomes.

              Dietary fiber and risk of coronary heart disease: a pooled analysis of cohort studies.

              Few epidemiologic studies of dietary fiber intake and risk of coronary heart disease have compared fiber types (cereal, fruit, and vegetable) or included sex-specific results. The purpose of this study was to conduct a pooled analysis of dietary fiber and its subtypes and risk of coronary heart disease. We analyzed the original data from 10 prospective cohort studies from the United States and Europe to estimate the association between dietary fiber intake and the risk of coronary heart disease. Over 6 to 10 years of follow-up, 5249 incident total coronary cases and 2011 coronary deaths occurred among 91058 men and 245186 women. After adjustment for demographics, body mass index, and lifestyle factors, each 10-g/d increment of energy-adjusted and measurement error-corrected total dietary fiber was associated with a 14% (relative risk [RR], 0.86; 95% confidence interval [CI], 0.78-0.96) decrease in risk of all coronary events and a 27% (RR, 0.73; 95% CI, 0.61-0.87) decrease in risk of coronary death. For cereal, fruit, and vegetable fiber intake (not error corrected), RRs corresponding to 10-g/d increments were 0.90 (95% CI, 0.77-1.07), 0.84 (95% CI, 0.70-0.99), and 1.00 (95% CI, 0.88-1.13), respectively, for all coronary events and 0.75 (95% CI, 0.63-0.91), 0.70 (95% CI, 0.55-0.89), and 1.00 (95% CI, 0.82-1.23), respectively, for deaths. Results were similar for men and women. Consumption of dietary fiber from cereals and fruits is inversely associated with risk of coronary heart disease.
