Psychological and metabolic risk factors in older adults with a previous history of eating disorder: A cross-sectional study from the Predimed-Plus study.

GOALS: To explore affective and cognitive status, later in life, in individuals with and without previous history of eating disorder (ED), and also its association with higher risk for metabolic syndrome (MetS) symptomatology. METHODS: A cross-sectional analysis of 6756 adults, aged 55-75 years with overweight/obesity and MetS participating in the Predimed-Plus study was conducted. Participants completed self-reported questionnaires to examine lifetime history of ED, according to DSM-5 criteria, and other psychopathological and neurocognitive factors. Anthropometric and metabolic measurements were also collected. RESULTS: Of the whole sample, 24 individuals (0.35%) reported a previous history of ED. In this subsample, there were more women and singles compared to their counterparts, but they also presented higher levels of depressive symptoms and higher cognitive impairment, but also higher body mass index (BMI) and severe obesity, than those without lifetime ED. CONCLUSIONS: This is one of the first studies to analyse the cognitive and metabolic impact of a previous history of ED. The results showed that previous ED was associated with greater affective and cognitive impairment, but also with higher BMI, later in life. No other MetS risk factors were found, after controlling for relevant variables.

Risk factors differentially associated with non-alcoholic fatty liver disease in males and females with metabolic syndrome.

BACKGROUND AND AIMS: non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in western countries. This study aimed to investigate putative risk factors differentially related with NAFLD in obese males and females diagnosed with metabolic syndrome (MetS), stratified using the non-invasive hepatic steatosis index (HSI). METHODS AND RESULTS: a cross-sectional analysis of the PREDIMED Plus study was performed of 278 participants with MetS (141 males and 137 females) of the Navarra-Nutrition node. Subjects were categorized by HSI tertiles and gender. Baseline clinical, biochemical variants and adherence to a Mediterranean diet and physical activity were evaluated. RESULTS: multivariate analyses showed that females had 4.54 more units of HSI (95% CI: 3.41 to 5.68) than males. Both sexes showed increased levels of triglycerides, TG/HDL cholesterol ratio and triglyceride glucose index across the HSI tertiles. Physical activity exhibited a negative statistical association with HSI (males: r = -0.19, p = 0.025; females: r = -0.18, p = 0.031). The amount of visceral fat showed a positive association with HSI in both sexes (males: r = 0.64, p < 0.001; females: r = 0.46, p < 0.001). Adherence to the Mediterranean diet was lower in those subjects with higher HSI values (males: r = -0.18, p = 0.032; females r= -0.19, p = 0.027). CONCLUSION: females had a poor liver status, suggesting gender differences related to NAFLD. Adherence to a Mediterranean diet and physical activity were associated with beneficial effects on cardiovascular disease features. Thus, reducing the risk of hepatic steatosis in subjects with MetS and obesity.

Effects of short- and long-term Mediterranean-based dietary treatment on plasma LC-QTOF/MS metabolic profiling of subjects with metabolic syndrome features: The Metabolic Syndrome Reduction in Navarra (RESMENA) randomized controlled trial.

SCOPE: Adherence to the Mediterranean diet has been associated with a reduced risk of metabolic syndrome (MetS). Metabolomics approach may contribute to identify beneficial associations of metabolic changes affected by Mediterranean diet-based interventions with inflammatory and oxidative-stress markers related to the etiology and development of the MetS. METHODS AND RESULTS: Liquid chromatography coupled to quadrupole-time of flight-MS metabolic profiling was applied to plasma from a 6-month randomized intervention with two sequential periods, a 2-month nutritional-learning intervention period, and a 4-month self-control period, with two energy-restricted diets; the RESMENA diet (based on the Mediterranean dietary pattern) and the Control diet (based on the American Heart Association guidelines), in 72 subjects with a high BMI and at least two features of MetS. The major contributing biomarkers of each sequential period were lipids, mainly phospholipids and lysophospholipids. Dependency network analysis showed a different pattern of associations between metabolic changes and clinical variables after 2 and 6 month of intervention, with a highly interconnected network during the nutritional-learning intervention period of the study. CONCLUSION: The 2-month RESMENA diet produced significant changes in the plasma metabolic profile of subjects with MetS features. However, at the end of the 6-month study, most of the associations between metabolic and clinical variables disappeared; suggesting that adherence to healthy dietary habits had declined during the self-control period.

Factores de riesgo asociados diferencialmente a la enfermedad de hígado graso no alcohólico en hombres y mujeres con síndrome metabólico / No disponible

INTRODUCCIÓN: el hígado graso no alcohólico (HGNA) es una enfermedad hepática crónica más prevalente en los países occidentales. OBJETIVOS: evaluar factores de riesgo asociados a HGNA en hombres y mujeres diagnosticados con SM estratificados según terciles del índice de esteatosis hepática (HSI). MÉTODOS: análisis transversal del estudio PREDIMED Plus (incluyendo únicamente información del nodo Navarra-Nutrición). Un total de 278 participantes (141 hombres y 137 mujeres) con SM fueron estratificados según terciles de HSI. El estudio analizó variables clínicas, bioquímicas e información sobre el estilo de vida, como grado de adherencia a la dieta mediterránea y práctica de actividad física. RESULTADOS: el análisis multivariante reveló que las mujeres tienen 4,54 unidades más de HSI (95% IC: 3,41 a 5,68) respecto a los hombres. Ambos sexos mostraron un incremento en los niveles de triglicéridos, TG/colesterol HDL e índice triglicéridos-glucosa (TyG) entre los terciles de HSI. Asimismo, se observó una asociación negativa entre la actividad física y el HSI (hombres: r = -0,19, p = 0,025; mujeres: r = -0,18, p = 0,031). La grasa visceral mostró una asociación positiva con el HSI en ambos sexos (hombres: r = 0,64, p < 0,001; mujeres: r = 0,46, p < 0,001). La adherencia a la dieta mediterránea es menor en los pacientes con HSI más elevado (hombres r = -0,18, p = 0,032; mujeres r = -0,19, p = 0,027). CONCLUSIONES: las mujeres presentan mayor riesgo de daño hepático y se sugieren importantes diferencias de sexo en relación a la EHGNA. La adherencia a la dieta mediterránea y la actividad física se reafirman como factores clave frente a la regulación de enfermedades cardiovasculares entre las que se encuentra la EHGNA. El riesgo de esteatosis hepática en población adulta obesa y con SM disminuye
