Hazardous alcohol use and alcohol use disorders in women : characteristics and vulnerability factors
The overall aim of this thesis was to study vulnerability factors
associated with hazardous alcohol consumption during pregnancy and
alcohol use disorders among Swedish women. Different risk-factors and
characteristics were studied, and examined for their ability to
discriminate or identify different subtypes (type I/late onset and type
II/early onset) of alcohol dependence ( alcoholism ).
In study I, an RCT at ANC in Stockholm (control, n = 156, intervention, n
=147) we examined the ability of Swedish antenatal care to identify
alcohol-related risk pregnancies, and the utility of some tools that
could improve its performance (AUDIT, TLFB and biomarkers). In study II,
a pilot cohort (n = 139) was screened for alcohol use disorders, and
assessed for psychopathology, personality traits, and alcohol use during
the first trimester. Subjects reporting consumption exceeding a
conservative threshold for harmful use were offered a diagnostic
psychiatric interview. The main findings of the pilot study were
replicated using a large sample of women in the third trimester (n =
715). In study III and IV, a case-control study, detailed assessment was
obtained from 200 treatment-seeking alcohol dependent women and 189
healthy population controls. All women were assessed for alcohol-related
behaviors, sexual abuse history, psychiatric problems, and personality
traits. Cases and controls were genotyped for markers in the CRHR1, MAOA
and OPRM1 genes. In study V, female twins from the Swedish Twin Registry
(n =13 501) answered questions to establish lifetime alcohol use
disorders, and subjects with alcoholism were classified for subtype.
Heritability estimates were obtained, and environmental factors
associated with alcoholism and its subtypes were studied.
Sixteen percent of pregnant women drank at levels that could be defined
as riskconsumption . Significantly more of these were identified by
intensified screening compared to regular antenatal screening procedures
(p = 0.0001), while biomarkers were of little use. Only a minority of
women with hazardous alcohol consumption during pregnancy fulfilled
alcohol dependence criteria. Psychiatric distress in those with
risk-consumption did not differ from those with low or no consumption
during pregnancy, but subjects with continued alcohol use scored higher
on novelty seeking. Among women with alcohol dependence, early onset/type
II alcoholism is a valid construct. We found that alcohol dependent women
classified as type II had more severe alcohol problems and significantly
higher rates of illicit drug use. Family history of alcoholism was also
considerably more common among type II than subjects than those
classified as type I. Both alcoholism subtypes scored higher than normal
on anxiety and impulsivity traits, but type II subjects scored markedly
higher than either of the other groups on aggression (p = 0.00004).
Despite a higher density of family history among type II subjects in the
clinical cohort, our twin study did not support a difference in
heritability between early onset/type II and late onset/type I
alcoholism. Both genetic and environmental factors play an important role
for susceptibility to alcoholism in women, in particular the early onset
subtype. Childhood trauma is a category of environmental factors that
plays a major role. The effect of emotional neglect and physical trauma
was accounted for by familial background factors, which can be both
genetic and environmental. In addition, childhood sexual abuse was an
independent individual risk factor for alcohol dependence. Effects of
sexual abuse were in part mediated trough psychiatric problems. Overall,
treatment-seeking alcohol dependent women with a history of abuse have
distinct features as compared to other alcohol dependent women

The Association Between High Birth Weight and Long-Term Outcomes—Implications for Assisted Reproductive Technologies: A Systematic Review and Meta-Analysis
Background: Studies have shown that the prevalence of children born with high birth weight or large for gestational age (LGA) is increasing. This is true for spontaneous pregnancies; however, children born after frozen embryo transfer (FET) as part of assisted reproductive technology (ART) also have an elevated risk. In recent years, the practice of FET has increased rapidly and while the perinatal and obstetric risks are well-studied, less is known about the long-term health consequences.Objective: The aim of this systematic review was to describe the association between high birth weight and LGA on long-term child outcomes.Data Sources: PubMed, Scopus, and Web of Science were searched up to January 2021. Exposure included high birth weight and LGA. Long-term outcome variables included malignancies, psychiatric disorders, cardiovascular disease, and diabetes.Study Selection: Original studies published in English or Scandinavian languages were included. Studies with a control group were included while studies published as abstracts and case reports were excluded.Data Extraction: The methodological quality, in terms of risk of bias, was assessed by pairs of reviewers. Robins-I (www.methods.cochrane.org) was used for risk of bias assessment in original articles. For systematic reviews, AMSTAR (www.amstar.ca) was used. For certainty of evidence, we used the GRADE system. The systematic review followed PRISMA guidelines. When possible, meta-analyses were performed.Results: The search included 11,767 articles out of which 173 met the inclusion criteria and were included in the qualitative analysis, while 63 were included in quantitative synthesis (meta-analyses). High birth weight and/or LGA was associated with low to moderately elevated risks for certain malignancies in childhood, breast cancer, several psychiatric disorders, hypertension in childhood, and type 1 and 2 diabetes.Conclusions: Although the increased risks for adverse outcome in offspring associated with high birth weight and LGA represent serious health effects in childhood and in adulthood, the size of these effects seems moderate. The identified risk association should, however, be taken into account in decisions concerning fresh and frozen ART cycles and is of general importance in view of the increasing prevalence in high birthweight babies

A healthy school start - Parental support to promote healthy dietary habits and physical activity in children: Design and evaluation of a cluster-randomised intervention
<p>Abstract</p> <p>Background</p> <p>Childhood obesity is multi-factorial and determined to a large extent by dietary habits, physical activity and sedentary behaviours. Previous research has shown that school-based programmes are effective but that their effectiveness can be improved by including a parental component. At present, there is a lack of effective parental support programmes for improvement of diet and physical activity and prevention of obesity in children.</p> <p>Methods/Design</p> <p>This paper describes the rationale and design of a parental support programme to promote healthy dietary habits and physical activity in six-year-old children starting school. The study is performed in close collaboration with the school health care and is designed as a cluster-randomised controlled trial with a mixed methods approach. In total, 14 pre-school classes are included from a municipality in Stockholm county where there is large variation in socio-economic status between the families. The school classes are randomised to intervention (n = 7) and control (n = 7) groups including a total of 242 children. The intervention is based on social cognitive theory and consists of three main components: 1) a health information brochure; 2) two motivational interviewing sessions with the parents; and 3) teacher-led classroom activities with the children. The primary outcomes are physical activity in the children measured objectively by accelerometry, children's dietary and physical activity habits measured with a parent-proxy questionnaire and parents' self-efficacy measured by a questionnaire. Secondary outcomes are height, weight and waist circumference in the children. The duration of the intervention is six months and includes baseline, post intervention and six months follow-up measurements. Linear and logistic regression models will be used to analyse differences between intervention and control groups in the outcome variables. Mediator and moderator analysis will be performed. Participants will be interviewed.</p> <p>Discussion</p> <p>The results from this study will show if it is possible to promote a healthy lifestyle and a normal weight development among children from low-income districts with relatively limited efforts involving parents. Hopefully the study will provide new insights to the further development of effective programmes to prevent overweight and obesity in children.</p> <p>Trial registration</p> <p>ISRCTN: <a href="http://www.controlled-trials.com/ISRCTN32750699">ISRCTN32750699</a></p

Genomic and drug target evaluation of 90 cardiovascular proteins in 30,931 individuals.
Circulating proteins are vital in human health and disease and are frequently used as biomarkers for clinical decision-making or as targets for pharmacological intervention. Here, we map and replicate protein quantitative trait loci (pQTL) for 90 cardiovascular proteins in over 30,000 individuals, resulting in 451 pQTLs for 85 proteins. For each protein, we further perform pathway mapping to obtain trans-pQTL gene and regulatory designations. We substantiate these regulatory findings with orthogonal evidence for trans-pQTLs using mouse knockdown experiments (ABCA1 and TRIB1) and clinical trial results (chemokine receptors CCR2 and CCR5), with consistent regulation. Finally, we evaluate known drug targets, and suggest new target candidates or repositioning opportunities using Mendelian randomization. This identifies 11 proteins with causal evidence of involvement in human disease that have not previously been targeted, including EGF, IL-16, PAPPA, SPON1, F3, ADM, CASP-8, CHI3L1, CXCL16, GDF15 and MMP-12. Taken together, these findings demonstrate the utility of large-scale mapping of the genetics of the proteome and provide a resource for future precision studies of circulating proteins in human health

Homozygosity has long been associated with rare, often devastating, Mendelian disorders1 and Darwin was one of the first to recognise that inbreeding reduces evolutionary fitness2. However, the effect of the more distant parental relatedness common in modern human populations is less well understood. Genomic data now allow us to investigate the effects of homozygosity on traits of public health importance by observing contiguous homozygous segments (runs of homozygosity, ROH), which are inferred to be homozygous along their complete length. Given the low levels of genome-wide homozygosity prevalent in most human populations, information is required on very large numbers of people to provide sufficient power3,4. Here we use ROH to study 16 health-related quantitative traits in 354,224 individuals from 102 cohorts and find statistically significant associations between summed runs of homozygosity (SROH) and four complex traits: height, forced expiratory lung volume in 1 second (FEV1), general cognitive ability (g) and educational attainment (nominal p<1 × 10−300, 2.1 × 10−6, 2.5 × 10−10, 1.8 × 10−10). In each case increased homozygosity was associated with decreased trait value, equivalent to the offspring of first cousins being 1.2 cm shorter and having 10 months less education. Similar effect sizes were found across four continental groups and populations with different degrees of genome-wide homozygosity, providing convincing evidence for the first time that homozygosity, rather than confounding, directly contributes to phenotypic variance. Contrary to earlier reports in substantially smaller samples5,6, no evidence was seen of an influence of genome-wide homozygosity on blood pressure and low density lipoprotein (LDL) cholesterol, or ten other cardio-metabolic traits. Since directional dominance is predicted for traits under directional evolutionary selection7, this study provides evidence that increased stature and cognitive function have been positively selected in human evolution, whereas many important risk factors for late-onset complex diseases may not have been
