AIM: This paper systematically reviews the literature on the effects of prenatal alcohol exposure on early child development from birth to 5 years with the aim to synthesize the developmental outcomes associated with prenatal alcohol exposure, and inform further research to improve our knowledge of the manifestations of prenatal alcohol exposure.

METHODS: Electronic databases (MEDLINE, Psych INFO, and Psych ARTICLES) were searched to find papers on the developmental outcomes of prenatal alcohol exposure in neonates, infants and toddlers and pre-school aged children. Studies were selected based on participants self-reporting alcohol consumption during pregnancy (either prospectively or retrospectively) and/or children being diagnosed with FASD based on a standardized assessment that includes a dysmorphology examination. The search was limited to peer-reviewed, English language studies involving human subjects, up to 5.5 years old.

RESULTS: Out of the 1,684 titles screened, a total of 71 papers were identified as relevant and included in this review. The majority of studies were prospective longitudinal studies. A range of assessment modalities (or tools) was used to determine neurodevelopmental outcomes of prenatal exposure to alcohol in the age group under review, the most frequently described being the Bayley Scales of Infant and Toddler Development (BSID) (n = 19). Studies varied in terms of the dose, frequency, and timing of alcohol consumption during pregnancy and methodology used to assess alcohol consumption. Findings demonstrate extensive evidence for poor global developmental outcomes in children prenatally exposed to alcohol, particularly with moderate to severe levels of prenatal alcohol exposure.

CONCLUSION: The outcomes related to lower levels of prenatal alcohol exposure as well as outcomes in specific developmental domains, are poorly understood. Further research should aim to clarify the more subtle or less easily measurable manifestations of prenatal alcohol exposure on early development when the potential for greatest impact of interventions is highest.

OBJECTIVES: Fetal alcohol spectrum disorders (FASD) is a worldwide problem. Maternal alcohol consumption is an important risk factor for FASD. It remains unknown which alcohol consumption patterns most strongly predict FASD. The objective of this study was to identify these.

DESIGN: Systematic literature review.

METHODS: We searched in PubMed, PsychINFO, PsycARTICLES, ERIC, CINAHL, Embase and MEDLINE up to August 2018. The query consisted of keywords and their synonyms related to FASD, pregnancy and behaviour. Studies were excluded when not published in English, were reviews or involved non-human subjects. Substantial heterogeneity precluded aggregation or meta-analysis of the data. Instead, data were qualitatively inspected.

RESULTS: In total, 21 studies were eligible for further data analysis. All studies that measured both maternal alcohol drinking behaviours and FASD reported retrospective data on maternal drinking patterns, employing both continuous and categorical measures and exhibiting substantial heterogeneity in measures of alcohol consumption (eg, timing of exposure, quantification of alcohol measure and definition of a standard drink). Study quality improved over time and appeared higher for studies based on active case ascertainment, especially when conducted in schools and when behaviour was assessed through interviews.

CONCLUSIONS: We aimed to identify specific maternal drinking behaviour(s) related to FASD. The state of the literature precludes such conclusions. Evidence-based preventive measures necessitate identifying which prenatal alcohol drinking behaviour(s) are most in need of intervention. Therefore, we formulate three recommendations for future research. First, future studies can optimise the value of the collected dataset through specifying measurements and reporting of maternal drinking behaviours and avoiding categorised measures (nominal or ordinal) whenever possible. Second, samples should not be selected based on FASD status, but instead, FASD status as well as maternal alcohol consumption should both be measured in a general population sample. Finally, we provide 10 reporting guidelines for FASD research.

Health benefits of moderate wine consumption have been studied during the past decades, first in observational studies and more recently, in experimental settings and randomized controlled studies. Suggested biological pathways include antioxidant, lipid regulating, and anti-inflammatory effects. Both the alcoholic and polyphenolic components of wine are believed to contribute to these beneficial effects. Although several of these studies demonstrated protective associations between moderate drinking and cardiovascular disease, atherosclerosis, hypertension, certain types of cancer, type 2 diabetes, neurological disorders, and the metabolic syndrome, no conclusive recommendations exist regarding moderate wine consumption. Yet, it is suggested that the physician and patient should discuss alcohol use. In the CASCADE (CArdiovaSCulAr Diabetes & Ethanol) trial, 224 abstainers with type 2 diabetes were randomized to consume red wine, white wine or mineral water for two years. Here, we summarize our previous findings, offer new evidence concerning the differential effects of wine consumption among men and women, and further suggest that initiating moderate alcohol consumption among well-controlled persons with type 2 diabetes is apparently safe, in regard to changes in heart rate variability and carotid plaque formation.

IMPORTANCE More than 1 million older adults develop heart failure annually. The association of alcohol consumption with survival among these individuals after diagnosis is unknown.OBJECTIVE To determine whether alcohol use is associated with increased survival among older adults with incident heart failure.DESIGN, SETTING, AND PARTICIPANTS This prospective cohort study included 5888 communitydwelling adults aged 65 years or older who were recruited to participate in the Cardiovascular HealthStudy between June 12, 1989, and June 1993, from 4 US sites. Of the total participants, 393 individuals had a new diagnosis of heart failure within the first 9 years of follow-up through June 2013. The study analysis was performed between January 19, 2016, and September 22, 2016.EXPOSURES Alcohol consumption was divided into 4 categories: abstainers (never drinkers), former drinkers, 7 or fewer alcoholic drinks per week, and more than 7 drinks per week.PRIMARY OUTCOMES AND MEASURES Participant survival after the diagnosis of incident heart failure.RESULTS Among the 393 adults diagnosed with incident heart failure, 213 (54.2%) were female, 339 (86.3%) were white, and the mean (SD) age was 78.7 (6.0) years. Alcohol consumption afterdiagnosis was reported in 129 (32.8%) of the participants. Across alcohol consumption categories of long-term abstainers, former drinkers, consumers of 1-7 drinks weekly and consumers of more than7 drinks weekly, the percentage of men (32.1%, 49.0%, 58.0%, and 82.4%, respectively; P < .001 for trend), white individuals (78.0%, 92.7%, 92.0%, and 94.1%, respectively, P <. 001 for trend), andhigh-income participants (22.0%, 43.8%, 47.3%, and 64.7%, respectively; P < .001 for trend) increased with increasing alcohol consumption. Across the 4 categories, participants who consumedmore alcohol had more years of education (mean, 12 years [interquartile range (IQR), 8.0-10.0 years], 12 years [IQR, 11.0-14.0 years], 13 years [IQR, 12.0-15.0 years], and 13 years [IQR, 12.0-14.0 years]; P < .001 for trend). Diabetes was less common across the alcohol consumption categories (32.1%, 26.0%, 22.3%, and 5.9%, respectively; P = .01 for trend). Across alcohol consumption categories, there were fewer never smokers (58.3%, 44.8%, 35.7%, and 29.4%, respectively; P < .001 for trend) and more former smokers (34.5%, 38.5%, 50.0%, and 52.9%, respectively; P = .006 for trend). After controlling for other factors, consumption of 7 or fewer alcoholic drinks per week was associated with additional mean survival of 383 days (95% CI, 17-748 days; P = .04) compared withabstinence from alcohol. Although the robustness was limited by the small number of individuals who consumed more than 7 drinks per week, a significant inverted U-shaped association between alcohol consumption and survival was observed. Multivariable model estimates of mean time from heart failure diagnosis to death were 2640 days (95% CI, 1967-3313 days) for never drinkers, 3046days (95% CI, 2372-3719 days) for consumers of 0 to 7 drinks per week, and 2806 (95% CI, 1879-3734 days) for consumers of more than 7 drinks per week (P = .02). Consumption of 10 drinks perweek was associated with the longest survival, a mean of 3381 days (95% CI, 2806-3956 days) after heart failure diagnosis.CONCLUSIONS AND RELEVANCE These findings suggest that limited alcohol consumption among older adults with incident heart failure is associated with survival benefit compared with long-termabstinence. These findings suggest that older adults who develop heart failure may not need to abstain from moderate levels of alcohol consumption.
