Consumo de fructosa y síndrome metabólico en pacientes adultos de un Hospital Militar / Fructose consumption and metabolic syndrome in adult patients of a military hospital

Introducción: La fructosa de la dieta se metaboliza a nivel hepático, en donde estimula la fructólisis, la glucólisis, la lipogénesis y la producción de glucosa, esto conlleva a la dislipidemia mixta, hiperglucemia e hígado graso; aumentando el riesgo de síndrome metabólico.Objetivo: Determinar la asociación entre el consumo de fructosa y síndrome metabólico en pacientes adultos atendidos en el Hospital Militar Central “Coronel Luis Arias Schreiber”.Materiales y Métodos: Investigación de enfoque cuantitativo, diseño no experimental, transversal, correlacional-causal. La población de estudio estuvo conformada por 75 pacientes adultos. Se incluyó pacientes mayores de 18 años de edad; quienes en forma voluntaria firmaron el consentimiento informado y presentaron registros actualizados de perfil bioquímico, fueron excluidos pacientes con discapacidad mental, motora y/o física. Los valores de presión arterial y perfil bioquímico; se obtuvo de las historias clínicas y la valoración antropométrica a través de la medición del peso corporal, talla y circunferencia abdominal; la ingesta de fructosa se obtuvo a través de un cuestionario de frecuencia de consumo semicuantitativo. Se utilizó la prueba estadística de Chi cuadrado para evaluar la asociación de variables.Resultados: El 61,3% presentó Síndrome Metabólico (SM), el 88% presentan un inadecuado consumo de fructosa (>25g/día). El índice de masa corporal (IMC) promedio fue de 30,34 (DE ±4,0); el nivel de glucosa en ayunas fue 100,13 mg/dL (DE ±11,25). Al asociar el consumo inadecuado de fructosa con el Síndrome Metabólico, se obtuvo un valor p= 0,010 (p<0,05). Asimismo, el consumo inadecuado de fructosa añadida tuvo asociación con el SM (p<0,05). No obstante, al asociar ingesta de fructosa natural con el SM, se obtuvo p =0.466 (p>0,05).(AU)

Introduction: Dietary fructose is metabolized in the liver,where it stimulates fructolysis, glycolysis, lipogenesis andglucose production, which leads to mixed dyslipidemia, hy-perglycemia and fatty liver; increasing the risk of metabolicsyndrome. Objetive: Determine the association between fructose con-sumption and metabolic syndrome in adult patients treated atthe “Coronel Luis Arias Schreiber” Central Military Hospital. Materials and methods: A quantitative approach studywas carried out, with a non-experimental, cross-sectional andcorrelational-causal design. The study population consisted of 75 adult patients. Patients over 18 years of age were in-cluded; who voluntarily signed the informed consent and pre-sented updated biochemical profile records. Patients withmental, motor and/or physical disabilities were excluded.Blood pressure and biochemical profile values were obtainedfrom medical records and anthropometric assessmentthrough measurement of body weight, height, and abdominalcircumference. Fructose intake was obtained through a semi-quantitative consumption frequency questionnaire. The Chisquare statistical test was used to evaluate the association ofvariables. Results: 61.3% presented Metabolic Syndrome (MS), 88%presented inadequate fructose consumption (>25g/day). Theaverage body mass index (BMI) was 30.34 (SD ±4.0); Thefasting glucose level was 100.13 mg/dL (SD ±11.25). Whenassociating inadequate fructose consumption with MetabolicSyndrome, a p value = 0.010 (p < 0.05) was obtained.Likewise, inadequate consumption of added fructose was as-sociated with MS (p<0.05). However, when associating natu-ral fructose intake with MS, p =0.466 (p>0.05) was obtained.Conclusions. A high consumption of added fructose in in-dustrialized foods has a greater association with the develop-ment of Metabolic Syndrome; It is necessary to reduce thefructose content in industrialized foods.(AU)

Dietary fructose and its association with the metabolic syndrome in Lebanese healthy adults: a cross-sectional study.

BACKGROUND: Epidemiological studies investigating the association between dietary fructose intake and the metabolic syndrome (MetS) are scarce and have produced controversial findings. This study aimed at (1) assessing total dietary fructose intake in a sample of Lebanese healthy adults, and determining the intake levels of natural vs. added fructose; (2) investigating the association of dietary fructose with MetS; and (3) identifying the socioeconomic and lifestyle factors associated with high fructose intake. METHODS: A cross-sectional survey was conducted on a representative sample of adults living in Beirut, Lebanon (n = 283). Anthropometric and biochemical data were collected, and dietary intake was assessed using a food frequency questionnaire. Intakes of naturally-occurring fructose from fructose-containing food sources, such as fruits, vegetables, honey, were considered as "natural fructose". Acknowledging that the most common form of added sugar in commodities is sucrose or High Fructose Corn Syrup (HFCS), 50% of added sugar in food products was considered as added fructose. Total dietary fructose intake was calculated by summing up natural and added fructose intakes. Logistic regression analyses were conducted to investigate the association of total, added and natural fructose intakes with the MetS and to identify the socioeconomic predictors of high fructose intake. RESULTS: Mean intake of total fructose was estimated at 51.42 ± 35.54 g/day, representing 6.58 ± 3.71% of energy intakes (EI). Natural and added fructose intakes were estimated at 12.29 ± 8.57 and 39.12 ± 34.10 g/day (1.78 ± 1.41% EI and 4.80 ± 3.56% EI), respectively. Participants in the highest quartile of total and added fructose intakes had higher odds of MetS (OR = 2.84, 95%CI: 1.01, 7.94 and OR = 3.18, 95%CI: 1.06, 9.49, respectively). In contrast, natural fructose intake was not associated with MetS. Age, gender and crowding index were identified as factors that may modulate dietary fructose intakes. CONCLUSIONS: The observed association between high added fructose intake and the MetS highlights the need for public health strategies aimed at limiting sugar intake from industrialized foods and promoting healthier dietary patterns in Lebanon.
