The realtionship between common patterns of prenatal alcohol exposure and the neurodevelopment of two-year old children

Background: Around 60% of women drink some alcohol while pregnant. There is conflicting evidence on the effect on the fetus of common patterns of prenatal alcohol exposure (PAE) e.g. low level or sporadic drinking. Guidelines recommend abstinence as the safest option, creating problems for those advising women who drink at these levels before pregnancy recognition or beyond. The Asking QUestions about Alcohol (AQUA) study aimed to accurately measure PAE and account for important cofactors, to reduce uncertainty about child outcomes. Method: Detailed data on PAE were prospectively collected in a pre-birth cohort of over 1500 mother/child dyads. There was also extensive data collection of predictors of child development at one and two-year's post-partum. A sub-group of children was followed up at two years of age with a neurodevelopmental assessment (Bayley III). Two-step multivariable regression analyses of an effect of PAE accounted for independent risk factors that related to 1) pregnancy, including sociodemographic, psychologic and lifestyle variables such as diet and supplement use, and 2) the postnatal care-giving environment, including breastfeeding and maternal psychological wellbeing. Results: Adjustment for independent risk factors ameliorated any putative associations between PAE and cognitive, language and motor development in 554 two year-old children spread evenly across six PAE groups. Conclusions: Assessing neurodevelopmental outcomes associated with PAE is strongly influenced by other modifiable and non-modifiable risk factors. Although we found no adverse neurodevelopmental outcomes at two years of age, follow-up will be necessary in these children when complex higher-level cognitive, language and motor skills are required

Prenatal alcohol exposure and facial shape of one-year old children: no amount of alcohol is without consequence

Background: Children with Fetal Alcohol Spectrum Disorder (FASD) can have a characteristic facial appearance in addition to neurodevelopmental impairment. We do not know if there is a gradient of effects on the face of children with prenatal alcohol exposure (PAE). Method: This is an analysis of 3D craniofacial images of 415 one year-old Caucasian children with detailed, prospectively collected PAE data. Analysis involved objective, holistic craniofacial phenotyping applying partial least-square regression to dense-surface models of the facial images. Results: We saw a significant association between craniofacial shape and PAE, whether exposure occurred only in trimester one, or throughout pregnancy. Regions of difference (p < 0.05) were concentrated around the mid-face, nose, lips and eyes. Directional visualisation showed these corresponded to general recession of the midface and superior displacement of the nose, especially the tip of the nose, indicating shortening of the nose and upturning of the nose tip. Significant differences existed between groups with no exposure and groups with low exposure in trimester one (forehead), moderate/high exposure in trimester one (eyes, midface, chin, parietal region) and binge level exposure in trimester one (chin). Conclusion: PAE, even at low levels, can influence craniofacial development. The observed differences were subtle, but are typical of dysmorphic features often seen in children with FASD. Although facial development is complex and each person's face is unique, it is sensitive to some influences at critical stages of development. Our study shows that alcohol contributes to how the face is formed in the womb

Hospitalisations for physical abuse in infants and children less than 5 years, 2013–2021: a multinational cohort study using administrative data from five European countries

Background: Child physical abuse (CPA) is a global public health problem associated with lifelong negative consequences, yet reliable epidemiologic data are lacking. This multinational cohort study analyses trends in CPA hospitalisations from 2013 to 2021. Methods: We used medico-administrative databases to identify children aged one month to five years hospitalised in Denmark, England, France, Ireland, and Wales. We identified CPA using a validated algorithm based on ICD-10 codes. We calculated the number, proportion, and incidence rate of children hospitalised for CPA, and the number and proportion of total hospitalisations for CPA, by year and age group (<1 and <5). We determined the proportion of CPA hospitalisations recorded using different ICD-10 codes, by country. Findings: The pooled incidence rate of infants <1 year hospitalised for CPA was stable over time (around 42/100,000 per year), ranging on average from 33 to 48/100,000 between countries. The pooled proportion of infant hospitalisations for CPA was around 0.17% (N = 750) per year (range 0.15–0.21%, N range 674–785), increasing significantly during the COVID-19 pandemic in 2020 (0.21%, N = 674). In children <5, the incidence rate (around 18/100,000 per year) and proportion of CPA hospitalisations (around 0.11% per year (N = 1600), range 0.10–0.14% (N range 1341–1657) were lower than in infants, but also increased in 2020 (0.14%, N = 1341). There were national differences in the distribution of ICD-10 codes used to record CPA and differences in year-on-year trends between countries. Interpretation: Comparing temporal trends in CPA hospitalisations between countries is feasible. Hospital data are one of several valuable sources for CPA surveillance

Women's knowledge and attitudes regarding alcohol consumption in pregnancy: a national survey

Background. Alcohol exposure in pregnancy is a common and modifiable risk factor for poor pregnancy and child outcomes. Alcohol exposure in pregnancy can cause a range of physical and neurodevelopmental problems in the child including the Fetal Alcohol Spectrum Disorders (FASD). In order to improve prevention strategies, we sought to describe the knowledge and attitudes of women of childbearing age regarding alcohol consumption during pregnancy and its effects on the fetus.Methods. We conducted a national cross-sectional survey via computer assisted telephone interview of 1103 Australian women aged 18 to 45 years. Participants were randomly selected from the Electronic White Pages. Pregnant women were not eligible to participate. Quotas were set for age groups and a minimum of 100 participants per state to ensure a national sample reflecting the population. The questionnaire was based on a Health Canada survey with additional questions constructed by the investigators. Descriptive statistics were calculated and logistic regression analyses were used to assess associations with participants' knowledge and attitudes.Results. Of women surveyed, 61.5% had heard about effects of alcohol on the fetus and 55.3% had heard of Fetal Alcohol Syndrome. Although 92.7% agreed alcohol can affect the unborn child, 16.2% did not agree that the disabilities could be lifelong. Most women agreed that pregnant women should not drink alcohol (80.2%) and 79.2% reported having negative feelings towards pregnant women drinking alcohol. Women with higher education levels were more likely to know the effects of alcohol consumption in pregnancy (adjusted OR 5.62; 95% CI 3.20 to 9.87) but education level and knowledge were not associated with attitude.Conclusions. There was a disjunction between knowledge and attitudes towards alcohol consumption in pregnancy. These findings will assist in developing effective health promotion campaigns to reduce fetal alcohol exposure and subsequent fetal damage

Attitudes and behaviour predict women's intention to drink alcohol during pregnancy: the challenge for health professionals

Background. To explore women's alcohol consumption in pregnancy, and potential predictors of alcohol consumption in pregnancy including: demographic characteristics; and women's knowledge and attitudes regarding alcohol consumption in pregnancy and its effects on the fetus. Methods. We conducted a national cross-sectional survey via computer assisted telephone interview of 1103 Australian women aged 18 to 45 years. Participants were randomly selected from the Electronic White Pages. Pregnant women were not eligible to participate. Quotas were set for age groups and a minimum of 100 participants per state to ensure a national sample reflecting the population. The questionnaire was based on a Health Canada survey with additional questions constructed by the investigators. Descriptive statistics were calculated and logistic regression analyses were used to assess associations of alcohol consumption in pregnancy with participants' characteristics, knowledge and attitudes.Results. The majority of women (89.4%) had consumed alcohol in the last 12 months. During their last pregnancy (n = 700), 34.1% drank alcohol. When asked what they would do if planning a pregnancy (n = 1103), 31.6% said they would consume alcohol and 4.8% would smoke. Intention to consume alcohol in a future pregnancy was associated with: alcohol use in the last pregnancy (adjusted OR (aOR) 43.9; 95% Confidence Interval (CI) 27.0 to 71.4); neutral or positive attitudes towards alcohol use in pregnancy (aOR 5.1; 95% CI 3.6 to 7.1); intention to smoke in a future pregnancy (aOR 4.7; 95% CI 2.5 to 9.0); and more frequent and higher current alcohol consumption. Conclusions. Women's past pregnancy and current drinking behaviour, and attitudes to alcohol use in pregnancy were the strongest predictors of alcohol consumption in pregnancy. Targeted interventions for women at higher risk of alcohol consumption in pregnancy are needed to change women's risk perception and behaviour

The genetic architecture of the human cerebral cortex

The cerebral cortex underlies our complex cognitive capabilities, yet little is known about the specific genetic loci that influence human cortical structure. To identify genetic variants that affect cortical structure, we conducted a genome-wide association meta-analysis of brain magnetic resonance imaging data from 51,665 individuals. We analyzed the surface area and average thickness of the whole cortex and 34 regions with known functional specializations. We identified 199 significant loci and found significant enrichment for loci influencing total surface area within regulatory elements that are active during prenatal cortical development, supporting the radial unit hypothesis. Loci that affect regional surface area cluster near genes in Wnt signaling pathways, which influence progenitor expansion and areal identity. Variation in cortical structure is genetically correlated with cognitive function, Parkinson's disease, insomnia, depression, neuroticism, and attention deficit hyperactivity disorder

Extending the K-12 art classroom into the after-school art club

textThe purpose of this study was to investigate how teachers are utilizing school sponsored art clubs after the school day ends. The research was comprised of two parts of data collection. The first was an electronic questionnaire that was dispersed to the entire visual art faculty in Round Rock Independent School District, Round Rock, Texas. The second part of the research consisted of semi-structured interviews with selected qualified participants. This research is intended to better prepare current art club sponsors and encourage other art educators to take on the responsibility of art club sponsorship at their school. Using mixed methodology, an investigation was made into art club purposes, curriculum, programs, activities, benefits and impacts on students, sponsors and schools. Through this research I have gained insight into how art clubs function in one specific suburban school district in Texas. I believe the information gained from this research can be helpful to other districts and art clubs for the benefit of both art club sponsors and art club members.Art Educatio
