Metabolic syndrome (MetS) is a constellation of risk factors for, in particular, cardiovascular diseases and increased mortality, and it constitutes a major clinical challenge affecting millions of lives. Alexithymia is a condition that has been linked with several mental diseases and symptoms, as well as somatic illnesses, including essential hypertension and diabetes mellitus. However, there is limited research on the association of alexithymia and MetS. The aim of the present study was to comprehensively explore this association in a large (n=1648) non-clinical sample of adults. Logistic regression analyses were applied to the five separate MetS components as well as the MetS diagnosis, and the analyses included a number of sociodemographic variables and depressive symptoms as covariates. The results confirmed the previous finding of alexithymic features being independently and significantly associated with hypertension. As a new finding, this association appears to be related to two particular dimensions of alexithymia, namely difficulty describing feelings and externally oriented thinking. Interestingly, alexithymic features were also separately significantly associated with waist circumference and triglycerides as well as the MetS diagnosis. Depressive symptoms did not have any significant effect on the relations of alexithymia and MetS. (C) 2015 Elsevier Ireland Ltd. All rights reserved.

Sex-specific role of alexithymia in associations between parental bonding and mental health: A moderated mediation model

Ru Li, Jani Kajanoja, Linnea Karlsson, Hasse Karlsson, Max Karukivi

Summary: This study explores the role of alexithymia in the association between perceived parental bonding and mental health, with a focus on potential sex differences. The findings suggest that alexithymia acts as a mediator, while sex plays a moderating role. Specifically, dysfunctional paternal bonding has a stronger impact on psychological symptoms in males.

Stress-Related Exhaustion, Polygenic Cognitive Potential, and Cognitive Test Performance - A General Population Study

Laila Ketvel, Liisa Keltikangas-Jarvinen, Katja Pahkala, Markus Juonala, Ari Ahola-Olli, Terho Lehtimaki, Jorma Viikari, Olli Raitakari, Suvi Rovio, Aino Saarinen

Summary: This study aimed to investigate the relationship between stress-related exhaustion (chronic or short-term, and co-occurring with depression or not) and cognitive performance, and whether polygenic cognitive potential modifies these associations. The study found that high stress-related exhaustion, especially chronic, was associated with slower reaction time. Clinical levels of depression were only related to slower reaction time. Polygenic cognitive potential did not modify these associations. There were no differences in cognitive performance between individuals with co-occurring exhaustion and depression vs. those with only either condition.

Neighbourhood deprivation in childhood and adulthood and risk of arterial stiffness: the Cardiovascular Risk in Young Finns study

Erika Kahonen, Satu Korpimaki, Markus Juonala, Mika Kahonen, Terho Lehtimaki, Nina Hutri-Kahonen, Olli T. Raitakari, Mika Kivimaki, Jussi Vahtera

Summary: Limited data is available on the association between neighbourhood deprivation and arterial stiffening. This study found that neighbourhood deprivation in childhood and adulthood predicts arterial stiffness indicated by pulse wave velocity (PWV). These findings suggest that neighbourhood deprivation and low adulthood socioeconomic status are independent risk factors for increased arterial stiffness in adulthood.

Spillover effects of the COVID-19 pandemic on attitudes to influenza and childhood vaccines

Anna Soveri, Linda C. Karlsson, Jan Antfolk, Otto Maki, Linnea Karlsson, Hasse Karlsson, Saara Nolvi, Max Karukivi, Mikael Lindfelt, Stephan Lewandowsky

Summary: This study aimed to investigate the impact of the COVID-19 pandemic on public perceptions of other vaccines and diseases. The results showed that during the pandemic, more people received or intended to receive the influenza vaccine compared to before. Participants also perceived influenza as more dangerous during the pandemic and believed vaccines to be safer and more beneficial. However, for childhood vaccines, only perceived safety increased. Additionally, trust in healthcare professionals increased during the pandemic. These findings suggest a spillover effect of the COVID-19 pandemic on how people view other vaccines and illnesses.

Summary: This study found that preterm birth is associated with a higher risk of mental and behavioral disorders in children aged 0-12 years, and the risk increases with the severity of prematurity. Other risk factors for preterm children include male gender, maternal mental health disorders, and smoking during pregnancy. These findings are important for understanding the etiology of childhood mental and behavioral disorders.

Summary: This study tested for protein leverage and the protein leverage hypothesis in children and adolescents. The results showed that proportional energy intake of proteins was inversely associated with energy intake, and increased energy intake on diets with lower protein content was counterbalanced by increased energy expenditure and did not lead to increased adiposity.

Course of child social-emotional and sleep symptoms, parental distress and pandemic-related stressors during COVID-19

Saara Nolvi, E. Juulia Paavonen, Riikka Korja, Juho Pelto, Max Karukivi, Jetro J. Tuulari, Hasse Karlsson, Linnea Karlsson

Summary: Research on the longitudinal courses of child social-emotional symptoms and sleep during the COVID-19 pandemic within societies would be of key value for promoting child well-being in global crises. We characterized the course of children's social-emotional and sleep symptoms before and throughout the pandemic in a Finnish longitudinal cohort of 1825 5- to 9-year-old children (46% girls) with four follow-up points during the pandemic from up to 695 participants (spring 2020-summer 2021). Second, we examined the role of parental distress and COVID-related stressful events in child symptoms. Child total and behavioral symptoms increased in spring 2020 but decreased thereafter and remained stable throughout the rest of the follow-up. Sleep symptoms decreased in spring 2020 and remained stable thereafter. Parental distress was linked with higher child social-emotional and sleep symptoms. The cross-sectional associations between COVID-related stressors and child symptoms were partially mediated by parental distress. The findings propose that children can be protected from the long-term adverse influences of the pandemic, and parental well-being likely plays a mediating role between pandemic-related stressors and child well-being. Further research focusing on the societal and resilience factors underlying family and child responses to the pandemic is warranted.

Satu Korpimaki, Suvi P. Rovio, Markus Juonala, Nina Hutri-Kahonen, Terho Lehtimaki, Tomi P. Laitinen, Paivi Tossavainen, Eero Jokinen, Britt-Marie Loo, Satu Mannisto, Tuija Tammelin, Atte Haarala, Heikki Aatola, Gaber Komar, Jorma Viikari, Olli Raitakari, Mika Kahonen, Katja Pahkala

Summary: This prospective study investigated the incidence and remission of nonalcoholic fatty liver disease (NAFLD) among a general Finnish population. The results showed that during the study period, every fifth participant without NAFLD at baseline developed NAFLD, and one-fifth of those with NAFLD at baseline achieved NAFLD remission. NAFLD became more prevalent during the follow-up period. From a clinical perspective, key predictors of NAFLD incidence and remission were BMI and waist circumference (WC) change independent of their baseline level.

Trait reactance as psychological motivation to reject vaccination: Two longitudinal studies and one experimental study

Anna Soveri, Linda C. Karlsson, Karl O. Maki, Dawn Holford, Angelo Fasce, Philipp Schmid, Jan Antfolk, Linnea Karlsson, Hasse Karlsson, Saara Nolvi, Max Karukivi, Mikael Lindfelt, Stephan Lewandowsky

Summary: This study investigates the impact of psychological motives on vaccine refusal. The longitudinal studies suggest that individuals with higher trait reactance are less willing to get vaccinated during the COVID-19 pandemic. The experimental study shows that highly reactant individuals' willingness to vaccinate is unaffected by the amount and framing of the information provided.
