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.

OBJECTIVES: To determine the effects of low-to-moderate levels of maternal alcohol consumption in pregnancy on pregnancy and longer-term offspring outcomes. SEARCH STRATEGY: Medline, Embase, Web of Science and Psychinfo from inception to 11 July 2016. SELECTION CRITERIA: Prospective observational studies, negative control and quasiexperimental studies of pregnant women estimating effects of light drinking in pregnancy (=32 g/week) versus abstaining. Pregnancy outcomes such as birth weight and features of fetal alcohol syndrome were examined. DATA COLLECTION AND ANALYSIS: One reviewer extracted data and another checked extracted data. Random effects meta-analyses were performed where applicable, and a narrative summary of findings was carried out otherwise. MAIN RESULTS: 24 cohort and two quasiexperimental studies were included. With the exception of birth size and gestational age, there was insufficient data to meta-analyse or make robust conclusions. Odds of small for gestational age (SGA) and preterm birth were higher for babies whose mothers consumed up to 32 g/week versus none, but estimates for preterm birth were also compatible with no association: summary OR 1.08, 95% CI (1.02 to 1.14), I2 0%, (seven studies, all estimates were adjusted) OR 1.10, 95% CI (0.95 to 1.28), I2 60%, (nine studies, includes one unadjusted estimates), respectively. The earliest time points of exposure were used in the analysis. CONCLUSION: Evidence of the effects of drinking =32 g/week in pregnancy is sparse. As there was some evidence that even light prenatal alcohol consumption is associated with being SGA and preterm delivery, guidance could advise abstention as a precautionary principle but should explain the paucity of evidence

Introduction The benefits of alcohol consumption for cardiovascular and metabolic health may have been overstated due to inappropriate comparisons with abstainers and inadequate control for confounding factors including physical activity and mental health. We examined alcohol consumption and cardio-metabolic health in a cohort of young Australian adults overcoming these limitations. Methods Cross-sectional data of a cohort of 2200 participants (age range 25-36 years) from the 2004-06 Childhood Determinants of Adult Health were used. Alcohol consumption was assessed from questionnaire and cardio-metabolic risk factors were measured in clinics. Linear and log binomial regression were used to examine total alcohol consumption (categories: none 0 g/day; light >0-10 g/day [reference]; moderate >10-20 g/day; heavy >20-30 g/day; very heavy >30 g/day) against dichotomous metabolic syndrome and its components: waist circumference, triglycerides, high-density lipoprotein cholesterol, blood pressure and glucose. Covariates included socio-demographics, smoking, diet, physical activity, fitness, depression and anxiety. Results Of the 2220 participants (48% males, mean (standard deviation) age 29.5 (2.5) years), most were classified in the 'light drinking' group (54.2%), less were in the 'non-drinking' (13.2%), 'heavy' (5.2%) or 'very heavy' (5.5%) drinking groups. Only moderate drinking was associated with a significantly lower prevalence of metabolic syndrome (prevalence ratio = 0.64, p < 0.05) compared with light drinking. Higher levels of alcohol consumption were associated with higher high-density lipoprotein cholesterol (beta = 0.05, ptrend < 0.001). Very heavy compared to light drinkers had higher systolic (beta = 3.01 mm Hg, p < 0.01) and diastolic (beta = 2.07 mm Hg, p < 0.05) blood pressure. Conclusion Moderate alcohol consumption was associated with a lower prevalence of MetS, and more favourable levels of lipids but not glucose or blood pressure even when compared to light consumption and with account for a range of confounding factors

BACKGROUND The relationship between alcohol consumption and metabolic syndrome (MetS) remains controversial. This study investigated the relationship between alcohol consumption and MetS components and prevalence.

MATERIAL AND METHODS We analyzed 10 037 subjects (3076 MetS and 6961 non-MetS) in a community-based cohort. MetS was defined according to the ATP III Guidelines. Subjects were divided according to amount of alcohol consumption; non-drinker, very light (0.1-5.0 g/day), light (5.1-15.0 g/day), moderate (15.1-30.0 g/day), and heavy drinker (>30 g/day). Multiple logistic regression models were performed to estimate odds ratios (ORs) and confidence intervals (CIs). The analyses were performed in men and women separately. SPSS statistical software was used for analyses.

RESULTS The prevalence of MetS in both males and females was associated with alcohol drinking status (p<0.0001). Amount of alcohol consumption (0.1-5.0 g/day) was significantly associated with lower prevalence of MetS in both genders compared to non-drinkers. Amount of alcohol consumption (>30.0 g/day) did not show a significant association with prevalence of MetS. However, alcohol consumption (>30.0 g/day) showed an association with glucose and HDL cholesterol among the components of MetS.

CONCLUSIONS Our results indicate that alcohol drinking (0.1-5.0 g/day) contributed to decrease prevalence of MetS and components, including triglyceride and HDL cholesterol.
