Childhood and long-term dietary calcium intake and adult cardiovascular risk in a population with high calcium intake
<p>Background & aims</p><p>The influence of dietary calcium intake in childhood on adult cardiovascular health is unknown, particularly in those with long-term high intake. To examine both linear and non-linear associations ...
DNA methylation signatures of aggression and closely related constructs: A meta-analysis of epigenome-wide studies across the lifespan
<p>DNA methylation profiles of aggressive behavior may capture lifetime cumulative effects of genetic, stochastic, and environmental influences associated with aggression. Here, we report the first large meta-analysis of epigenome-wide association studies (EWAS) of aggressive behavior (N = 15,324 participants). In peripheral blood samples of 14,434 participants from 18 cohorts with mean ages ranging from 7 to 68 years, 13 methylation sites were significantly associated with aggression (alpha = 1.2 × 10<sup>-7</sup>; Bonferroni correction). In cord blood samples of 2425 children from five cohorts with aggression assessed at mean ages ranging from 4 to 7 years, 83% of these sites showed the same direction of association with childhood aggression (r = 0.74, p = 0.006) but no epigenome-wide significant sites were found. Top-sites (48 at a false discovery rate of 5% in the peripheral blood meta-analysis or in a combined meta-analysis of peripheral blood and cord blood) have been associated with chemical exposures, smoking, cognition, metabolic traits, and genetic variation (mQTLs). Three genes whose expression levels were associated with top-sites were previously linked to schizophrenia and general risk tolerance. At six CpGs, DNA methylation variation in blood mirrors variation in the brain. On average 44% (range = 3-82%) of the aggression-methylation association was explained by current and former smoking and BMI. These findings point at loci that are sensitive to chemical exposures with potential implications for neuronal functions. We hope these results to be a starting point for studies leading to applications as peripheral biomarkers and to reveal causal relationships with aggression and related traits.</p>...
Long-term tracking and population characteristics of lipoprotein (a) in the Cardiovascular Risk in Young Finns Study
<p>Background and aims</p><p>Lipoprotein (a) (Lp(a)) is a causal risk factor for cardiovascular diseases and its levels are under strict genetic control. Therefore, it is hypothesized that the concentration of Lp(a) remains ...
Uncovering the shared lipidomic markers of subclinical osteoporosis-atherosclerosis comorbidity: The Young Finns Study
<p>Background: Osteoporosis and atherosclerosis are complex multifactorial diseases sharing common risk factors and pathophysiological mechanisms suggesting that these are comorbidities. Omics studies identifying joint ...
Assessment of plasma ceramides as predictor for subclinical atherosclerosis
<p>Background and aims</p><p>Ceramides have been identified as novel biomarkers for cardiovascular disease (CVD) related events and mortality but their role in etiology of subclinical atherosclerosis is unknown. We aimed ...
Genetic and observational evidence: No independent role for cholesterol efflux over static high-density lipoprotein concentration measures in coronary heart disease risk assessment
<p>Background <br></p><p>Observational findings for high-density lipoprotein (HDL)-mediated cholesterol efflux capacity (HDL-CEC) and coronary heart disease (CHD) appear inconsistent, and knowledge of the genetic architecture ...
Does better education mitigate risky health behavior? A mendelian randomization study
<p><br></p><p>Education and risky health behaviors are strongly negatively correlated. Education may affect health behaviors by enabling healthier choices through higher disposable income, increasing information about the ...

Childhood and Adulthood Passive Smoking and Nonalcoholic Fatty Liver in Midlife: A 31-year Cohort Study
INTRODUCTION: Identifying early life risk factors remains key to the prevention of nonalcoholic fatty liver (hereinafter "fatty liver") in adulthood. However, the longitudinal association of childhood passive smoking with ...
IDO activity forecasts obesity in males and premenopausal females in a 10-year follow-up study:The Cardiovascular Risk in Young Finns Study
<p>Background and aims: Indoleamine 2,3-dioxygenase (IDO) is an intracellular enzyme associated with artery wall inflammation. Previous studies have verified correlation between IDO activity and early signs of atherosclerosis especially in females. We aimed to elucidate the relationship between an estimate of IDO activity and atherosclerotic risk factors related to non-alchohol-fatty liver (NAFLD) in a 6- and 10-year follow-up.<br></p><p>Methods: Estimates of IDO activity along with complete risk factor data were measured from females (n = 506; age 24-39) and males (n = 421; age 24-39) in 2001. Risk factor measurements were conducted again in 2007 and 2011. Statistical examinations were carried out by Pearson correlation and risk ratio analysis.<br></p><p>Results: In females, age-adjusted IDO correlated with body mass index (BMI) (p = 0.0008), waist (p = 0.0009), C reactive protein (CRP) (p = 0.0014) and logarithmically modified triglycerides (p = 0.0488) in 2007. Correlation remained significant with BMI (p = 0.0007) and waist (p = 0.0063) in 2011. In males, age-adjusted IDO correlated with waist (p = 0.0367) and high-density lipoprotein cholesterol (HDL-C) (p = 0.0489) in 2007. Correlation remained significant with HDL-C (p = 0.0348) in 2011. In risk ratio analysis, relationship between IDO and obesity was confirmed in females after 10 years (RR = 1.026, p = 0.0147, 95% CI) and in males after 6 and 10 years (RR = 1.019, p = 0.0091, 95% CI and RR = 1.015, p = 0.0404, 95% CI, respectively) when the data was adjusted for age and BMI.Conclusions: IDO activity correlated with obesity and factors related to NAFLD, namely obesity of visceral type, hypertriglyceridemia and CRP (in females), well-characterized risk factors for diabetes and atherosclerosis in 6 and 10-year follow-up in males and premenopausal females.</p>...
