Nutrients. 2021;(8)
Abstract
Alcohol use has been causally linked to more than 200 disease and injury conditions, as defined by three-digit ICD-10 codes. The understanding of how alcohol use is related to these conditions is essential to public health and policy research. Accordingly, this study presents a narrative review of different dose-response relationships for alcohol use. Relative-risk (RR) functions were obtained from various comparative risk assessments. Two main dimensions of alcohol consumption are used to assess disease and injury risk: (1) volume of consumption, and (2) patterns of drinking, operationalized via frequency of heavy drinking occasions. Lifetime abstention was used as the reference group. Most dose-response relationships between alcohol and outcomes are monotonic, but for diabetes type 2 and ischemic diseases, there are indications of a curvilinear relationship, where light to moderate drinking is associated with lower risk compared with not drinking (i.e., RR < 1). In general, women experience a greater increase in RR per gram of alcohol consumed than men. The RR per gram of alcohol consumed was lower for people of older ages. RRs indicated that alcohol use may interact synergistically with other risk factors, in particular with socioeconomic status and other behavioural risk factors, such as smoking, obesity, or physical inactivity. The literature on the impact of genetic constitution on dose-response curves is underdeveloped, but certain genetic variants are linked to an increased RR per gram of alcohol consumed for some diseases. When developing alcohol policy measures, including low-risk drinking guidelines, dose-response relationships must be taken into consideration.

Journal of the American Academy of Dermatology. 2021;(3):701-711
Abstract
BACKGROUND Psoriatic arthritis (PsA) is a progressive joint disease associated with psoriasis. OBJECTIVES To investigate the association of modifiable lifestyle and environmental factors with PsA risk among people with psoriasis. METHODS We conducted a systematic search of PubMed, Embase, and Cochrane Library through May 2, 2020, for observational studies reporting lifestyle or environmental factors for PsA onset in patients with psoriasis. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were combined using a random-effects model. RESULTS We included 16 studies comprising 322,967 individuals. Obesity and being overweight were associated with an increased PsA risk in patients with psoriasis (OR, 1.75 [95% CI, 1.42-2.16] and OR, 1.50 [95% CI, 1.08-2.09], respectively), with an increase of approximately 6% for each kg/m2 rise in body mass index (OR, 1.06; 95% CI, 1.03-1.10). The presence of PsA was associated with a history of physical trauma (OR, 1.33; 95% CI, 1.16-1.54) or fracture (OR, 1.46; 95% CI, 1.22-1.74). No significant associations were observed regarding alcohol consumption (OR, 0.99; 95% CI, 0.88-1.13), smoking (OR, 0.89; 95% CI, 0.75-1.06), female hormonal exposure (OR, 1.45; 95% CI, 0.95-2.20), and psychologically traumatic events. LIMITATIONS Inherent limitations in the included observational studies. CONCLUSIONS Several lifestyle and environmental factors are associated with PsA onset among patients with psoriasis. These findings indicate that such risk may be modified with lifestyle changes or avoidance of physical trauma in people with psoriasis.

Alcohol and alcoholism (Oxford, Oxfordshire). 2020;(3):246-253
Abstract
AIMS: Alcohol intake has been shown to increase the risk of breast cancer. However, the dose-response analysis of different alcoholic beverages (spirits, wine and beer) is not clear. Our meta-analysis aims to provide a dose-response estimation between different alcohols and breast cancer risk. METHODS Search of PubMed and Web of Science and manual searches were conducted up to 1 December 2018, and summary relative risks (RRs) and attributable risk percentage (ARP) for alcohol intake on the development of breast cancer were calculated. Dose-response meta-analysis modeled relationships between drinking type and breast cancer risk. Sources of heterogeneity were explored, and sensitivity analyses were conducted to test the robustness of findings. RESULTS In total, 22 cohort studies and 45,350 breast cancer cases were included. Current drinkers for ER+ had an increased risk compared with never drinkers. In dose-response analysis, there was a statistically significant linear trend with breast cancer risk increasing gradually by total alcohol and wine dose: when adding 10 g per day, the risk increased by 10.5% (RR = 1.10, 95%CI = 1.08-1.13) in total alcohol and 8.9% (RR = 1.08, 95%CI = 1.04-1.14) in wine. For postmenopausal women, the risk increases by 11.1% (RR = 1.11, 95%CI = 1.09-1.13) with every 10 g of total alcohol increase. Furthermore, the breast cancer alcohol-attributed percentage is higher in Europe than in North America and Asia. CONCLUSIONS The effect of drinking on the incidence of breast cancer is mainly manifested in ER+ breast cancer. Quantitative analysis showed total drinking had a significant risk for breast cancer, especially for postmenopausal women. However, for different alcohols, just wine intake has the similar results.

Abstract
BACKGROUND Some previous studies have reported inconsistent results on the association between alcohol intake and diabetic retinopathy (DR) risk. This study aimed to evaluate the potential effects of alcohol intake on subsequent DR risk using a meta-analytic approach. METHODS Three electronic databases (PubMed, EmBase, and the Cochrane library) were systematically searched for observational studies from their inception till November 2019. The pooled odds ratio (OR) with 95% confidence interval (CI) were applied for the summary effect estimate using a random-effects model. RESULTS A total of 15 studies (5 cohort studies, 4 case-control studies, and 6 cross-sectional studies) with 37,290 participants and 12,711 DR cases were selected for the final meta-analysis. The pooled OR indicated no significant association between alcohol intake and DR risk (OR: 0.91; 95%CI: 0.78-1.06; P = 0.225), irrespective of the studies being pooled cohort (OR: 0.95; 95%CI: 0.66-1.36; P = 0.761), case-control (OR: 0.97; 95%CI: 0.77-1.23; P = 0.818), or cross-sectional (OR: 0.86; 95%CI: 0.69-1.08; P = 0.190) ones. However, this association might have been affected by the type of diabetes mellitus and the adjusted status. CONCLUSION The results of this study showed that the potential impact of alcohol intake on DR risk may differ according to the type of diabetes mellitus and adjusted status. Further large-scale, prospective cohort studies should be conducted to verify the findings of this study and to evaluate DR risk in relation to the dose and type of alcohol intake.

Nutrients. 2020;(8)
Abstract
Alcohol is widely consumed and is known as a major risk factor for several types of cancers. Yet, it is unclear whether alcohol consumption is associated with the risk of prostate cancer (PCa) or not. We conducted linear and non-linear dose-response meta-analyses of cohort studies on alcohol consumption and PCa risk by types of alcohol (total, wine, beer, and liquor) and PCa (non-aggressive and aggressive). Pubmed and Embase were searched through April 2020 to identify relevant studies. Summary relative risk (RR) and 95% confidence interval (CI) were estimated using a random-effects model. For non-aggressive PCa, by alcohol type, the risk increased linearly with liquor (RR per 14 g/day intake (alcohol content in standard drink) being 1.04 (95% CI = 1.02-1.06, I2 = 0%, three studies) and non-linearly with beer (Pnon-linearity = 0.045, four studies), with increased risk observed in the lower range (RR = 1.03, 95% CI = 1.01-1.05; 14 g/day), with 1.05 (95% CI = 1.01-1.08) at 28 g/day. Wine was not significantly associated with the risk of non-aggressive PCa. For aggressive PCa, a non-linear relationship of diverse shapes was indicated for all types of alcohol in the sensitivity analysis. Compared to non-drinking, a significant positive association was more apparent at lower dose for liquor (RR = 1.12, 95% CI = 1.04-1.20 at 14 g/day; RR = 1.16, 95% CI = 1.03-1.31 at 28 g/day; Pnon-linearity = 0.005, three studies) but at higher doses for wine (RR = 1.02, 95% CI = 0.90-1.16 at 28 g/day, RR = 1.35, 95% CI = 1.08-1.67 at 56 g/day; Pnon-linearity = 0.01, four studies). In contrast, decreased risks were indicated at lower doses of beer (RR = 0.85, 95% CI = 0.79-0.92 at 14 g/day; RR = 0.79, 95% CI = 0.70-0.90 at 28 g/day, Pnon-linearity < 0.001, four studies). Total alcohol consumption was not associated with both types of PCa. In this study, we found heterogeneous associations between alcohol intake and PCa by types of alcohol and PCa.

Alcohol and alcoholism (Oxford, Oxfordshire). 2020;(5):457-467
Abstract
AIMS: We conducted a dose-response meta-analysis to explore the association between alcohol and particular alcoholic beverages with risk of esophageal cancer (EC) by histological type [esophageal squamous cell carcinoma (ESCC) and esophageal adenocarcinoma (EAC)] and whether the association differs according to gender. METHODS PubMed and Web of Science databases were searched for relevant articles published between January 1960 and December 2019. The pooled relative ratios (RRs) and 95% confidence interval (CI) were calculated with the fixed or random effect model. The dose-response relationship was assessed by restricted cubic spline. RESULTS A total of 74 published articles involving 31,105 cases among 3,369,024 participants were included in this meta-analysis. The pooled RRs of the highest versus lowest alcohol intake were 3.67 (95% CI, 2.89,4.67) for EC, 5.11 (95% CI, 3.60,7.25) for ESCC and 0.96 (95% CI, 0.79,1.16) for EAC. The above-mentioned associations were observed in cohort design, for different alcoholic beverages (beer, wine and liquor/spirits) and gender. Evidence of a nonlinear dose-response relationship for EC risk with alcohol intake was found (Pnon-linearity < 0.001), and a linear relationship (Pnon-linearity = 0.216) suggested that the risk of ESCC increased by 33% for every 12.5 g/day increment of alcohol intake. CONCLUSIONS This meta-analysis suggests that alcohol intake might significantly increase the incidence of EC, especially for ESCC.

Abstract
Excessive alcohol consumption is one of the main causes of death and disability worldwide. Alcohol consumption is a heritable complex trait. Here we conducted a meta-analysis of genome-wide association studies of alcohol consumption (g d-1) from the UK Biobank, the Alcohol Genome-Wide Consortium and the Cohorts for Heart and Aging Research in Genomic Epidemiology Plus consortia, collecting data from 480,842 people of European descent to decipher the genetic architecture of alcohol intake. We identified 46 new common loci and investigated their potential functional importance using magnetic resonance imaging data and gene expression studies. We identify genetic pathways associated with alcohol consumption and suggest genetic mechanisms that are shared with neuropsychiatric disorders such as schizophrenia.

Abstract
Tobacco and alcohol use are leading causes of mortality that influence risk for many complex diseases and disorders1. They are heritable2,3 and etiologically related4,5 behaviors that have been resistant to gene discovery efforts6-11. In sample sizes up to 1.2 million individuals, we discovered 566 genetic variants in 406 loci associated with multiple stages of tobacco use (initiation, cessation, and heaviness) as well as alcohol use, with 150 loci evidencing pleiotropic association. Smoking phenotypes were positively genetically correlated with many health conditions, whereas alcohol use was negatively correlated with these conditions, such that increased genetic risk for alcohol use is associated with lower disease risk. We report evidence for the involvement of many systems in tobacco and alcohol use, including genes involved in nicotinic, dopaminergic, and glutamatergic neurotransmission. The results provide a solid starting point to evaluate the effects of these loci in model organisms and more precise substance use measures.

Cancer epidemiology, biomarkers & prevention : a publication of the American Association for Cancer Research, cosponsored by the American Society of Preventive Oncology. 2019;(11):1891-1901
Abstract
BACKGROUND Although an association between alcohol consumption and risk of colorectal cancer is well established, little is known about the association between alcohol consumption and colorectal cancer survival. We conducted a meta-analysis of prospective cohort studies to quantitatively assess this association. METHODS Data searches were performed using PubMed and ISI Web of Science databases through December 2018. We estimated pooled RRs with 95% confidence intervals (CI) using random-effects models. RESULTS Twelve studies with 32,846 patients with colorectal cancer were included in the meta-analysis. Compared with no alcohol consumption, light (RR = 0.87; 95% CI, 0.81-0.94) and moderate (RR = 0.92; 95% CI, 0.85-1.00) prediagnostic alcohol consumption were associated with lower risk of all-cause mortality. Light prediagnostic alcohol consumption was associated with lower risk of colorectal cancer-specific mortality (RR = 0.87; 95% CI, 0.78-0.98). However, heavy prediagnostic alcohol consumption was not significantly associated with colorectal cancer survival. In a dose-response analysis, a nonlinear association between prediagnostic alcohol consumption and all-cause mortality was observed (P nonlinearity = 0.0025), showing the reduction in RR at <30 g/day of alcohol consumption. By type of alcohol, wine consumption was associated with lower risk of mortality from all-causes and colorectal cancer, but a positive association was observed between moderate liquor consumption and all-cause mortality. There was no association between postdiagnostic alcohol consumption and colorectal cancer survival. CONCLUSIONS Light and moderate prediagnostic alcohol consumption were associated with better survival in colorectal cancer. IMPACT Our findings suggest that light and moderate alcohol consumption may be associated with better survival in colorectal cancer, but further studies are warranted.

Abstract
BACKGROUND The challenge of addressing unhealthy lifestyle choice is of global concern. Motivational Interviewing has been widely implemented to help people change their behaviour, but it is unclear for whom it is most beneficial. This overview aims to appraise and synthesise the review evidence for the effectiveness of Motivational Interviewing on health behaviour of adults in health and social care settings. METHODS A systematic review of reviews. Methods were pre-specified and documented in a protocol (PROSPERO-CRD42016049278). We systematically searched 7 electronic databases: CDSR; DARE; PROSPERO; MEDLINE; CINAHL; AMED and PsycINFO from 2000 to May 2018. Two reviewers applied pre-defined selection criteria, extracted data using TIDIER guidelines and assessed methodological quality using the ROBIS tool. We used GRADE criteria to rate the strength of the evidence for reviews including meta-analyses. FINDINGS Searches identified 5222 records. One hundred and four reviews, including 39 meta-analyses met the inclusion criteria. Most meta-analysis evidence was graded as low or very low (128/155). Moderate quality evidence for mainly short term (<6 months) statistically significant small beneficial effects of Motivational Interviewing were found in 11 of 155 (7%) of meta-analysis comparisons. These outcomes include reducing binge drinking, frequency and quantity of alcohol consumption, substance abuse in people with dependency or addiction, and increasing physical activity participation. CONCLUSIONS We have created a comprehensive map of reviews relating to Motivational Interviewing to signpost stakeholders to the best available evidence. More high quality research is needed to be confident about the effectiveness of Motivational Interviewing. We identified a large volume of low quality evidence and many areas of overlapping research. To avoid research waste, it is vital for researchers to be aware of existing research, and the implications arising from that research. In the case of Motivational Interviewing issues relating to monitoring and reporting fidelity of interventions need to be addressed.
