Publication Open Access Interplay of the mediterranean diet and genetic hypertension risk on blood pressure in european adolescents: findings from the HELENA study(Springer, 2024) Pérez-Gimeno, Gloria; Seral-Cortes, Miguel; Sabroso-Lasa, Sergio; Esteban, Luis Mariano; Widhalm, Kurt; Gottrand, Frédéric; Stehle, Peter; Meirhaeghe, Aline; Muntaner, Manon; Kafatos, Antonios; Gutiérrez, Ángel; Manios, Yannis; Anastasiou, Costas A.; González Gross, Marcela; Breidenassel, Christina; Censi, Laura; Henauw, Stefaan de; Labayen Goñi, Idoia; Bueno-Lozano, Gloria; Rupérez, Azahara I.; Moreno, Luis A.; Ciencias de la Salud; Osasun Zientziak; Institute on Innovation and Sustainable Development in Food Chain - ISFOODEarly-life onset of high blood pressure is associated with the development of cardiovascular diseases in adulthood. In adolescents, limited evidence exists regarding the association between adherence to the Mediterranean Diet (MedDiet) and normal blood pressure (BP) levels, as well as its potential to modulate genetic predisposition to HTN. This study investigated the interaction between a MedDiet score and a recently developed HTN-genetic risk score (HTN-GRS) on blood pressure levels in a European adolescent cohort. The MedDiet score was derived from two non-consecutive 24-h dietary recalls and ranged from 0 (indicating low adherence) to 9 (indicating high adherence). Multiple linear regression models, adjusted for covariates, were employed to examine the relationship between the MedDiet score and BP z-scores and to assess the interaction effects between the MedDiet score and HTN-GRS on BP z-scores. MedDiet score showed a negative association with z-systolic BP (SBP) (ß = -0.40, p < 0.001) and z-diastolic BP (DBP) (ß = -0.29, p = 0.001). Additionally, a significant interaction effect was identified between the MedDiet score and HTN-GRS on z-SBP (ß = 0.02, p < 0.001) and z-DBP (ß = 0.02, p < 0.001). The modulatory effect of the MedDiet was more pronounced in females than in males, and HTN-GRS exhibited a stronger influence on DBP than on SBP. Conclusion: The study suggests that higher adherence to the MedDiet is associated with reduced BP levels in adolescents and provides evidence of a genetic-diet interaction influencing BP in adolescents. (Table presented.)Publication Open Access The body mass index increases the genetic risk scores' ability to predict risk of hepatic damage in European adolescents: the HELENA study(Wiley, 2023) Seral-Cortes, Miguel; Sabroso-Lasa, Sergio; González Gross, Marcela; Quesada-González, Carlos; Stehle, Peter; Gottrand, Frédéric; Marcos, Ascensión; Diaz, Ligia Esperanza; Manios, Yannis; Androutsos, Odysseas; Widhalm, Kurt; Molnár, Dénes; Huybrechts, Inge; Muntaner, Manon; Meirhaeghe, Aline; Salazar-Tortosa, Diego; Ruiz, Jonatan R.; Esteban, Luis Mariano; Labayen Goñi, Idoia; Moreno, Luis A.; Ciencias de la Salud; Osasun ZientziakBackground: Hepatic disorders are often complex and multifactorial, modulated by genetic and environmental determinants. During the last years, the hepatic disease has been progressively established from early stages in life. The use of genetic risk scores (GRS) to predict the genetic susceptibility to a particular phenotype among youth has gained interest in recent years. Moreover, the alanine aminotransferase (ALT) blood biomarker is often considered as hepatic screening tool, in combination with imaging techniques. The aim of the present study was to develop an ALT-specific GRS to help in the evaluation of hepatic damage risk in European adolescents. Methods: A total of 972 adolescents (51.3% females), aged 12.5¿17.5 years, from the Healthy Lifestyle in Europe by Nutrition in Adolescence study were included in the analyses. The sample incorporated adolescents in all body mass index (BMI) categories and was divided considering healthy/unhealthy ALT levels, using sex-specific cut-off points. From 1212 a priori ALT-related single nucleotide polymorphisms (SNPs) extracted from candidate gene selection, a first screening of 234 SNPs univariately associated was established, selecting seven significant SNPs (p <.05) in the multivariate model. An unweighted GRS (uGRS) was developed by summing the number of reference alleles, and a weighted GRS (wGRS), by multiplying each allele to its estimated coefficient. Results: The uGRS and wGRS were significantly associated with ALT (p <.001). The area under curve was obtained integrating BMI as clinical factor, improving the predictive ability for uGRS (.7039) and wGRS (.7035), using 10-fold internal cross-validation. Conclusions: Considering BMI status, both GRSs could contribute as complementary tools to help in the early diagnosis of hepatic damage risk in European adolescents.
