These differences are influenced by environmental and genetic factors. Early childhood adversity is a well-studied environmental factor affecting an individual's stress response which has been shown to be modulated by gene environment interaction (GxE). Neuropeptide Y (NPY) plays a role in stress regulation and genetic variation in NPY may influence stress responses. In this study, we analyzed the association of a common variant in the NPY gene promoter, rs16147, with cortisol and ACTH responses to acute psychosocial stress in young adults from the Mannheim Study of Children at Risk (MARS), an ongoing epidemiological cohort study following the outcome of early adversity from birth into adulthood. We found evidence of a GxE interaction between rs16147 and early adversity significantly affecting HPA axis responses to acute psychosocial stress. These findings suggest that the neurobiological mechanisms linking early adverse experience and later neuroendocrine stress regulation are modulated by a gene variant whose functional relevance is documented by increasing convergent evidence from in vitro, animal and human studies.}, language = {en} } @article{SchmidBlomeyerBuchmannetal.2011, author = {Schmid, Brigitte and Blomeyer, Dorothea and Buchmann, Arlette F. and Trautmann-Villalba, Patricia and Zimmermann, Ulrich S. and Schmidt, Martin H. and Esser, G{\"u}nter and Banaschewski, Tobias and Laucht, Manfred}, title = {Quality of early mother-child interaction associated with depressive psychopathology in the offspring - a prospective study from infancy to adulthood}, series = {Journal of psychiatric research}, volume = {45}, journal = {Journal of psychiatric research}, number = {10}, publisher = {Elsevier}, address = {Oxford}, issn = {0022-3956}, doi = {10.1016/j.jpsychires.2011.05.010}, pages = {1387 -- 1394}, year = {2011}, abstract = {Evidence from animal research has revealed that less maternal care results in disturbed emotionality in the offspring.

At age 3 months, mothers and infants were videotaped during a nursing and playing situation. Maternal responsiveness and stimulation as well as infant responsiveness were evaluated by trained raters. At age 19 years, 314 participants (145 males, 169 females) were characterized on measures of depression through interview and questionnaire. In addition, measures of depression and anxiety were available from assessments in childhood. Results indicated that less maternal stimulation during early interaction was associated with a higher risk of depression in the offspring until the age of 19 years. In addition, children of less stimulating mothers showed more depressive symptoms at age 19 years and displayed more anxiety and depressive symptoms between the ages of 4.5 and 15 years. In contrast, maternal responsiveness was unrelated to children's outcome. In accordance with findings from animal research, the present study provides first longitudinal evidence in humans of a continuous and long-term influence of early maternal interaction behavior on the offspring's psychological adjustment until adulthood. The results suggest that the amount of maternally initiated contact behavior in a very early developmental stage may be crucial for children's mental health, regardless of child and maternal responsiveness.}, language = {en} } @misc{AlbeckGidronBaraldiBethkeetal.2011, author = {Albeck-Gidron, Rachel and Baraldi, Luca and Bethke, Svenja and Dallapiazza, Michael and Denz, Rebekka and Dordanas, Stratos N. and Dubrau, Alexander and Feinberg, Anat and Gerhardt, Kristiane and Gr{\"o}zinger, Elvira and Gr{\"o}zinger, Karl E. and Hiscott, William and J{\"u}tte, Robert and Kalogrias, Vaios and Kinzel, Tanja and Knufinke, Ulrich and Lewy, Mordechay and Liska, Vivian and Riemer, Nathanael and Schmidt Holl{\"a}nder, Hanna and Solomon, Francisca and Szulc, Michał and Talabardon, Susanne and Ulmer, Martin and Wagner, Birgitt}, title = {PaRDeS : Zeitschrift der Vereinigung f{\"u}r J{\"u}dische Studien e.V. = Ghetto : R{\"a}ume und Grenzen im Judentum}, number = {17}, editor = {Denz, Rebekka and Jurewicz, Grażyna}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, isbn = {978-3-86956-132-5}, issn = {1614-6492}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-49387}, year = {2011}, abstract = {Unter Rekurs auf zwei historische Erscheinungsformen des Ghettos - auf j{\"u}dische Wohnviertel der Fr{\"u}hen Neuzeit und nationalsozialistische Ghettos - wurde der Begriff ‚Ghetto' zum Symbol von Joch und Verfolgung stilisiert.

Metabolic factors associated with increased risk for cardiovascular disease have been found to vary, depending on lifestyle as well as genetic predisposition. Moreover, there is evidence suggesting that environmental conditions, such as stress in pre- and postnatal life, may have a sustained impact on an individual's metabolic risk profile. Methods: Participants were drawn from a prospective, epidemiological, cohort study followed up from birth into young adulthood. Parent interviews and behavioral observations at the age of 3 months were conducted to assess child-rearing practices and mother-infant interaction in the home setting and in the laboratory. In 279 participants, anthropometric characteristics, low-density lipoprotein and high-density lipoprotein cholesterol, apolipoproteins, and triglycerides were recorded at age 19 years. In addition, structured interviews were administered to the young adults to assess indicators of current lifestyle and education. Results: Adverse early-life interaction experiences were significantly associated with lower levels of high- density lipoprotein cholesterol and apolipoprotein A1 in young adulthood. Current lifestyle variables and level of education did not account for this effect, although habitual smoking and alcohol consumption also contributed significantly to cardiometabolic outcomes.

Results: In contrast to various previous reports, a significant G x E emerged, indicating that, when exposed to high psychosocial adversity, individuals with the LL genotype of 5-HTTLPR exhibited more hazardous drinking than those carrying the S allele or those without exposure to adversity. This effect, which was confined to male participants, held both for different classifications of 5-HTTLPR and different types of adversity.

Two hundred and ninety-one young adults (135 males, 156 females) participating in the Mannheim Study of Children at Risk were genotyped for the 40-bp variable number of tandem repeats (VNTR) and rs27072 polymorphisms of DAT1. Age at initiation was assessed at age 15 and 19 years. Information about current alcohol and tobacco consumption was obtained at age 19 years using self-report measures and structured interviews. Results suggest that age at onset of intensive consumption moderated the association of the DAT1 gene with early adult substance use and dependence, revealing a DAT1 effect only among individuals homozygous for the 10r allele of the 40-bp VNTR who had started daily smoking or being intoxicated early in life. Equally, carriers of the T allele of the rs27072 polymorphism reporting an early age at first intoxication showed higher current alcohol consumption at age 19 years. In contrast, no interaction between rs27072 and the age at first cigarette with regard to later smoking was observed.

Data on risk factors, including early family adversity, parental alcohol use, childhood psychopathology and stressful life events, were repeatedly collected during childhood using standardized parent interviews. In addition, information on genotype was considered. Results confirmed previous work demonstrating that hazardous alcohol consumption is related to early-adolescent drinking onset. A younger age of first drink was significantly predicted by 5-HTTLPR genotype and the degree of preceding externalizing symptoms, and both factors were related to increased consumption or harmful alcohol use at age 19. However, even after controlling for these potential explanatory factors, earlier age at drinking onset remained a strong predictor of heavy alcohol consumption in young adulthood.

Assessments of adolescent drug consumption and related intrapersonal characteristics were obtained at age 15. Results: Compared to consumers of alcohol only, 15-year-olds drinking and smoking during the same time period (past 4 weeks) had significantly higher levels of consumption and more excessive use of alcohol, started drinking at an earlier age, had higher scores on the Fagerstrom Test for Nicotine Dependence, and more cannabis use. This group could be distinguished from users of alcohol only by higher novelty seeking and more positive alcohol effect expectancies.

No significant differences were observed regarding frequency and age at initiation of tobacco use, tobacco-related sensitivity, self- efficacy and instrumentality as well as novelty seeking.
