27 September 2018 In Drinking & Eating Patterns

BACKGROUND: Recent trends in alcoholic liver disease, alcohol-related emergency room admissions, and alcohol use disorder prevalence as measured by general-population surveys have raised concerns about rising alcohol-related morbidity and mortality in the United States. In contrast, upward trends in per capita alcohol consumption have been comparatively modest.

METHODS: To resolve these discordant observations, we sought to examine trends in the prevalence of alcohol use and binge drinking from 6 regularly or periodically administered national surveys using a meta-analytic approach. Annual or periodic prevalence estimates for past-12-month or past-30-day alcohol use and binge drinking were estimated for available time points between the years 2000 and 2016. Estimates were combined in a random-effects regression model in which prevalence was modeled as a log-linear function of time to obtain meta-analytic trend estimates for the full population and by sex, race, age, and educational attainment.

RESULTS: Meta-analysis-derived estimates of average annual percentage increase in the prevalence of alcohol use and binge drinking were 0.30% per year (95% CI: 0.22%, 0.38%) and 0.72% per year (95% CI: 0.46%, 0.98%), respectively. There was substantial between-survey heterogeneity among trend estimates, although there was notable consistency in the degree to which trends have impacted various demographic groups. For example, most surveys found that the changes in prevalence for alcohol use and binge drinking were large and positive for ages 50 to 64 and 65 and up, and smaller, negative, or nonsignificant for ages 18 to 29.

CONCLUSIONS: Significant increases in the prevalence of alcohol use and of binge drinking over the past 10 to 15 years were observed, but not for all demographic groups. However, the increase in binge drinking among middle-aged and older adults is substantial and may be driving increasing rates of alcohol-related morbidity and mortality.

BACKGROUND/OBJECTIVES: Low/moderate alcohol consumption seems to be protective against cardiovascular disease (CVD). This study aimed to investigate the association of wine/beer consumption with the 10-year CVD incidence.

SUBJECTS/METHODS: During 2001-2002, 3042 CVD-free adults consented to participate in the ATTICA study; of them 2583 completed the 10-year follow-up (85% participation rate), but precise information about fatal/nonfatal CVD incidence (myocardial infarction, angina pectoris, cardiac ischemia, heart failure, chronic arrhythmias, and stroke) was available in 2020 participants (overall retention rate 66%). Alcohol/ethanol intake and the alcoholic beverages consumed were assessed; participants were categorized into three groups (no use; 1 glass/week).

RESULTS: Alcohol drinking was reported by 56% of the participants who did not develop a CVD event and 49% of those who had (p = 0.04); whereas ethanol intake was 14 +/- 16 g among those who did not had an event vs. 21 +/- 18 g among those who had a CVD event (p < 0.001). A strong inverse and similar association between low wine/beer intake (20 g/day had CVD-risk HRs (95% CI) of 0.60 (0.40-0.98), 1.22 (0.60-1.14), and 1.81 (0.70-4.61), respectively.

CONCLUSIONS: This study revealed similar results of low wine/beer consumption against CVD incidence, mainly due to its implication on low-grade chronic inflammation.

BACKGROUND AND OBJECTIVES: Although prenatal alcohol and nicotine exposure are associated with reduced cognition in children, associations between consumption of alcohol during lactation and cognition have not been examined. We aimed to examine whether drinking or smoking while breastfeeding lowers children's cognitive scores. We hypothesized that increased drinking or smoking would be associated with dose-dependent cognitive reductions.

METHODS: Data were sourced from Growing Up in Australia: The Longitudinal Study of Australian Children. Participants were 5107 Australian infants recruited in 2004 and assessed every 2 years. Multivariable linear regression analyses assessed relationships between drinking and smoking habits of breastfeeding mothers and children's Matrix Reasoning, Peabody Picture Vocabulary Test-Third Edition and Who Am I? scores at later waves.

RESULTS: Increased or riskier wave 1 maternal alcohol consumption was associated with reductions in Matrix Reasoning scores at age 6 to 7 years in children who had been breastfed (B = -0.11; SE = 0.03; 95% confidence interval: -0.18 to -0.04; P = .01). This relationship was not evident in infants who had never breastfed (B = -0.02; SE = 0.10; 95% confidence interval = -0.20 to 0.17; P = .87). Smoking during lactation was not associated with any outcome variable.

CONCLUSIONS: Exposing infants to alcohol through breastmilk may cause dose-dependent reductions in their cognitive abilities. This reduction was observed at age 6 to 7 years but was not sustained at age 10 to 11 years. Although the relationship is small, it may be clinically significant when mothers consume alcohol regularly or binge drink. Further analyses will assess relationships between alcohol consumption or tobacco smoking during lactation and academic, developmental, physical, and behavioral outcomes in children.

OBJECTIVE: Premenstrual syndrome (PMS) is a very common disorder worldwide which carries an important economic burden. We conducted a systematic review and a meta-analysis to assess the role of alcohol in the occurrence of PMS.

METHODS: We searched MEDLINE, EMBASE, the five regional bibliographic databases of the WHO, the Proceedings database and the Open Access Thesis and Dissertations (OATD) from inception to May 2017. We also reviewed the references of every article retrieved and established personal contact with researchers to trace further publications or reports. We did not include any language limitations. Studies were included if: (1) they presented original data from cohort, case-control or cross-sectional studies, (2) PMS was clearly defined as the outcome of interest, (3) one of the exposure factors was alcohol consumption, (4) they provided estimates of odds ratios, relative risks, or any other effect measure and their confidence intervals, or enough data to calculate them.

RESULTS: We identified 39 studies of which 19 were eligible. Intake of alcohol was associated with a moderate increase in the risk of PMS (OR=1.45, 95% CI: 1.17 to 1.79). Heavy drinking yielded a larger increase in the risk than any drinking (OR=1.79, 95% CI: 1.39 to 2.32).

DISCUSSION: Our results suggest that alcohol intake presents a moderate association with PMS risk. Future studies should avoid cross-sectional designs and focus on determining whether there is a threshold of alcohol intake under which the harmful effect on PMS is non-existent.
