Alcohol and non-traffic unintended injuries. We were also able to examine the shape of the association between alcohol consumption >14 units/week and dementia, which was similar to that reported in a recent meta-analysis.7 Dose-response assessment by meta-analysis can be problematic for heavy alcohol consumption as the estimate is constrained to the mean or median consumption in the high alcohol consumption category.7 Finally, we used multistate models to examine the role of cardiometabolic disease and we undertook further analyses to take the competing risk of mortality into account where results were similar to those obtained using Cox regression, increasing confidence in our main findings. . Age at dementia diagnosis was 76.1, 75.7, and 74.4 years (P=0.13) in the abstinence, 1-14 units/week, and >14 units/week groups, respectively. British Medical Journal, i, 6052. Complication Rates Suicide Within 12 months of the abortion or live delivery, Scandinavian women who aborted experienced a suicide rate of 34.9 per 1000, compared to a suicide rate of 5.9 per 1000 for women who delivered their babies. A recent meta-analysis of observational studies concluded that light to moderate alcohol consumption is associated with a reduced risk of dementia, whereas both abstinence and heavy drinking are associated with a higher risk of dementia.7 In seven of the 10 studies included in the analysis, the mean follow-up period was less than 10 years, with alcohol consumption being assessed later in life and thus potentially modified by health related problems.11 In two of the three other studies, the CAIDE35 and the Finnish Twin36 cohorts, although a U-shaped association was suggested, results were not robust owing to the small number of cases in the extreme alcohol consumption categories. While there is almost universal agreement that heavy drinking is associated with cognitive impairment, numerous observational studies do report that light to moderate consumption is associated with a reduced risk of all cause dementia. Alcohol as a risk factor for injury or death resulting from accidental falls: A review of the literature. UK Chief Medical Officers. British medical journal (Clinical research ed.) Compared with participants in the long term consumption 1-14 units/week group, those with long term abstinence (1.74, 1.31 to 2.30), decreased consumption (1.55, 1.08 to 2.22), and long term consumption >14 units/week (1.40, 1.02 to 1.93) had a higher risk of dementia. Mortality data were drawn from the British national mortality register (National Health Services Central Registry). British Medical Journal, 294, 534 - 536. Not that pills don't help but exercise is far better, and a combination of pills and exercise may be unbeatable. We all wish that the dipping mercury was only. Nevertheless, studies using other approaches such as mendelian randomisation39 and brain imaging data from a subsample of the Whitehall II study40 suggest linear adverse effects of alcohol consumption. UK chief medical officers alcohol guidelines review: Summary of the proposed new guidelines. Some people have heard that the use of marijuana can drive you nuts. Secondary analysis of mortality from all causes showed lower risk for drinkers compared with non-drinkers (relative risk 0.87 (0.83 to 0.92)). We simulated two scenarios: first where the correlation of the two sensitivity (specificity) distributions in the alcohol consumption groups was 0.8 and then 0.6 (a correlation of 1 would correspond to non-differential misclassification). Among these participants, a total of 397 cases of dementia were recorded over a mean follow-up of 23.2 (SD 4.4, range 0.08-25.6) years. However how a lot of you knew there's another side to marijuana consumption. If you have a subscription to The BMJ, log in: Subscribe and get access to all BMJ articles, and much more. Finally, to examine whether poor sensitivity of our method of dementia ascertainment biased our results, we simulated scenarios with differential misclassification (ie, the hypothesis that proportion of misclassified dementia cases depends on midlife alcohol consumption categories) using a SAS macro provided by Fox et al.31 We allowed the sensitivity to range between 60% and 90% and the specificity between 97% and 100% using a trapezoidal probability density function. Even moderate drinking is linked to pathological changes in the brain, Epidemiological studies often report better heath in moderate drinkers compared with abstainers. Skin disease in Lambeth.

Association of alcohol consumption trajectories between 1985/88 and 2002/04 with risk of dementia. 22nd May 2017. The maintenance of brain health is central to health and wellbeing across the lifespan.1 Evidence suggests three periods of dynamic brain changes that may be particularly sensitive to the neurotoxic effects of alcohol: gestation (from conception to birth), later adolescence (15-19 years), and older adulthood (over 65 years). Journal Scan Medical Journal Armed Forces India. 11 This study also . From fetal development to later life, the human brain goes through several periods of dynamic change. Covariates were assessed in 1991/93 (or the closest wave if missing), apart for the analysis on hospital admission for alcohol related chronic diseases, for which all covariates were time varying. UK Chief Medical Officers Low Risk Drinking Guidelines 2016. We accounted for several sociodemographic and health related characteristics in the analysis, but residual confounding cannot be excluded as an explanation for the higher risk of dementia among abstainers.

Regression Modeling Strategies: With Applications to Linear Models, Logistic Regression, and Survival Analysis. Abstinence in midlife was associated with a higher risk of dementia (hazard ratio 1.47, 95% confidence interval 1.15 to 1.89) compared with consumption of 1-14 units/week. In a study based on the Swedish Twin Registry with 43 years of follow-up, where dementia was assessed through electronic health records, a quadratic association was found whereby both no alcohol consumption and high alcohol consumption were associated with an increased risk of dementia, although the excess risk in abstainers did not reach statistical significance and the excess risk of high consumption began at 12 g/day (corresponding to around 10.5 units/week).37 The study also found, as in our investigation, a reduced risk of dementia for moderate wine consumption and a linear increased risk of dementia in those consuming spirits. 11 this was because of accumulating evidence that even light drinking increases the risk of various malignancies. Data using hospital admission for chronic disease caused by high alcohol consumption showed a four times higher risk of dementia, supporting findings on the neurotoxic effects of alcohol consumption >14 units/week. TIL of a study published in the British Medical Journal in 2018 concluding that parachutes does not reduce risk of death or major injury when jumping from an aircraft. These associations remained after adjustment for behavioural and health related factors (table 3). This brief four item scale (felt need to Cut down on drinking, Annoyed by people criticising your drinking, Guilty about drinking, Need a drink first thing (Eye-opener)).21 It is a validated screening instrument for alcohol dependence that was originally developed for general practice settings and correlates well with a clinical diagnosis of alcoholism.

Published Thursday in the British medical journal The Lancet, the massive genetic study of 160,000 adults adds to growing research that alcohol can have lasting health implications. Regarded as a further example of the J shaped curve, a protective effect of moderate alcohol consumption against all cause dementia has been reported.5 This has not been underpinned by a convincing neural correlate, however, and it is here that the linked study by Topiwala and colleagues (doi:10.1136/bmj.j2353) is particularly ambitious.6 In their prospective cohort of 550 civil servants, none of whom were alcohol dependent, the authors repeatedly assessed alcohol consumption and cognition over 30 years. METHODS Performance effects were studied in the same subjects over a period of 28 hours of sleep deprivation and after measured doses of alcohol up to about 0.1% blood alcohol concentration (BAC). DO carry out hand hygiene (use soap and water or alcohol rub), and wash carefully, . Indeed, this group is particular in that it is composed mainly of women from the lower socioeconomic group with higher prevalence of cardiometabolic risk factors and disease at baseline, a pattern that has also been observed in other studies.3537, Alcohol abstinence is also associated with a higher risk of diabetes and cardiovascular disease,115 which might increase the risk of dementia.416 A recent study of nearly 600000 people, for example, found a J-shaped association between alcohol consumption and cardiovascular disease, with a weekly alcohol consumption of 100 g (12.5 units) being associated with the lowest risk of cardiovascular disease and a higher disease risk observed in those consuming smaller amounts of alcohol.14 Moderate alcohol consumption has been hypothesised to benefit cardiovascular health through favourable impacts on lipid profile, inflammation level, endothelial function, and insulin sensitivity.1338 In agreement with this, a meta-analysis of interventional studies (alcohol use versus a period of no alcohol use) reported that moderate alcohol consumption had favourable effects on levels of high density lipoprotein cholesterol, apolipoprotein A1, adiponectin, and fibrinogen,38 potentially underlying the apparent neuroprotective effects of moderate alcohol consumption. technical support for your product directly (links go to external sites): Thank you for your interest in spreading the word about The BMJ.

Breaking news headlines about British Medical Journal linking to 1,000s of websites from around the world. We identified five trajectories of alcohol consumption (appendix figure S1): long term abstinence (9% of participants were in this group), decreased consumption (6%), long term consumption 1-14 units/week group (59%), increased consumption (11%), and long term consumption >14 units/week (14%). It is also the world's highest-impact academic journal. As intake increases, so does the risk to health, probably in a dose dependent manner. In analysis adjusted for sociodemographic factors, one hospital admission or more for alcohol related chronic disease over follow-up was associated with a 4.3 times higher risk of dementia (95% confidence interval 2.7 to 6.7).

No participants were asked advice on interpretation or writing up of results. Design A survey questionnaire assessed alcohol consumption using the Alcohol Use Disorders . Analysis based on 2143 participants free of cardiometabolic disease and dementia in 1991/93; 709 participants had incident cardiometabolic disease (among whom 34 developed dementia); among healthy participants 32 had dementia. The journal is published by. WHO. Moderate alcohol consumption is thought to be associated with a lower risk of dementia; the association of alcohol with cognitive outcomes appears to be J-shaped or U-shaped, with harmful effects of both abstinence and excessive alcohol consumption, The evidence is far from robust, however, as excessive alcohol consumption is not included in current guidelines to prevent or delay dementia onset, Inconsistency in findings stems from the fact that most studies assess alcohol consumption in late life, which may not reflect lifetime consumption, and selection bias is likely to affect these findings as studies used face-to-face assessment of cognitive status, The results show a greater risk of dementia in those who abstain from alcohol or consume >14 units/week, with risk increasing in a linear fashion at higher levels of consumption, Data on hospital admission for chronic disease caused by high alcohol consumption showed a fourfold higher risk of dementia in these people, The study also found support for a mediating role of cardiometabolic disease; some of the excess risk of dementia in abstainers was explained by greater risk of cardiometabolic disease in this group. A community study of prevalence and use medical care. UKB is a prospective cohort study for which baseline biomedical and physical assessments were carried out 2006-2013, in 502 682 adults aged 40-69 years recruited from 22 UK centres.23 Ocular assessments occurred during the latter phase (2009-2013; seven centres) and included visual acuity, autorefraction, digital fundus photography with the Topcon 3D-OCT 1000 Mark . Fourthly, we examined the associations of type of alcohol consumed using mean midlife consumption (1985/88, 1989/90, and 1991/93) using restricted cubic splines adjusted for sociodemographic variables and mutually adjusted for types of alcohol consumed.

Health behaviours were assessed over the follow-up period by questionnaire and included smoking (current, former, never), hours of moderate to vigorous physical activity (using questions on moderately energetic (eg, dancing, cycling, leisurely swimming) and vigorous (eg, running, hard swimming, playing squash) physical activity at baseline and then using a modified version of the Minnesota leisure time physical activity questionnaire),25 and dietary behaviour (frequency of fruit and vegetables consumed in a week). Yes! The aim of this study was to assess changes in insulin resistance, metabolic risk factors and cancer-related growth factors with short-term abstinence from alcohol in moderate drinkers. This study aims to assess the causal associations of alcohol consumption and smoking with psoriasis. A prospective study of the health effects of alcohol consumption in middle-aged and elderly men. A recent study32 reported that passive assessment of dementia through UK hospital records has high specificity but modest sensitivity (78%) owing to milder cases of dementia being missing, as also found in the Mayo Clinic Study of Aging and the Adult Changes study.33 In addition to hospital records, we used other sources of dementia diagnosis, such as the UK mental health database, which is likely to improve the sensitivity of dementia diagnosis. Written informed consent from participants and research ethics approvals were renewed at each contact. We repeated these analyses to assess the impact of differential misclassification on the comparison between alcohol consumption of >14 units/week compared with 1-14 units/week. Data sharing: Data, protocols, and other metadata of the Whitehall II study are available to the scientific community.

As a minimum, people should stay away from work two to three days with a cold, and for the first week of influenza, recommends Dr Brooks. British Columbia Medical Journal. Since alcohol use varies greatly by study area, in each of the ten study areas mean male alcohol intake was calculated for each of these nine genotypes (assigning occasional drinkers an intake of 5 g per week and excluding ex-drinkers, which effectively assigns them the mean intake in other participants in their area). Analysis adjusted for age, sex, ethnicity, education, occupational position, and marital status. Alcohol consumption in mild cognitive impairment and dementia: harmful or neuroprotective? ISSN 0267-0623 Related Title: BMA news BMJ (International ed.) The chief medical officer recently changed guidance for low risk drinking in men, reducing the recommended maximum intake from 21 to 14 units a week.11 This was because of accumulating evidence that even light drinking increases the risk of various malignancies.12 The relation between alcohol and brain health is more complex than the relation between alcohol and cancer. To reduce measurement error we used the mean of consumption measured in 1985/88, 1989/90, and 1991/93. Three sets of analyses were undertaken (fig 1 and appendix table S1). If there is a single elixir of life it is not popping pills in the hope of being forever young and disease-free; it is exercising. Alcohol and Public Health: Alcohol-Related Disease Impact (ARDI). It is possible that systematic reporting biases affected findings, although comparison of alcohol consumption reported by the participants of the Whitehall II study suggests patterns similar to those in several other UK cohort studies.11 The use of multiple approaches, including the measures of hospital admission for alcohol related chronic disease with converging findings, suggest that our results on excessive alcohol consumption are robust. In several countries, guidelines define thresholds for harmful alcohol consumption much higher than 14 units/week. Existing on a spectrum of severity, alcohol related brain damage typically involves relatively young people, often in their 40s or 50s, meaning the more severely affected require decades of institutional care. Topiwala and colleagues findings strengthen the argument that drinking habits many regard as normal have adverse consequences for health. These features, along with a mean follow-up period of 23 years, allowed a comprehensive assessment of the association of alcohol consumption with dementia. The journal publishes original research articles, review articles ("seminars" and "reviews"), editorials, book reviews, correspondence, as well as news features and case reports.

The Epidemiology and Impact of Dementia: Current State and Future Trends. Methods: We conducted an observational study using population health administrative data from the BC . Conclusion The risk of dementia was increased in people who abstained from alcohol in midlife or consumed >14 units/week. They had an average of 6.3 years of bartending experience. STORY HIGHLIGHTS The study uses a new scale to rank the. The Whitehall II study is an ongoing cohort study of men and women originally employed by the British civil service in London based offices.17 A total of 10308 adults (6895 men and 3413 women, aged 35-55) were recruited during 1985-88. 3 With binge drinking on the rise, these figures are likely to increase. As studies usually assess alcohol consumption only once, excess risk might be driven by the inclusion of former drinkers in the same group as abstainers.7 Our analyses using repeat data on alcohol consumption across midlife suggest that former drinking might not explain the excess dementia risk in abstainers, although we cannot exclude the possibility that those who report alcohol abstinence in midlife were heavy drinkers in young adulthood or misreported their alcohol consumption. Abstinence was associated with a higher risk of dementia when the reference was alcohol consumption of 14 units/week; in these analyses alcohol consumption >14 units/week was associated with an increased risk of dementia in a linear fashion (among those drinking >14 units/week, P for non-linearity=0.97 using spline regressions). As these three categories had similar hazards of dementia (see appendix table S2), we combined them into a single category of abstinence. Among drinkers, we categorised average alcohol consumption (1985/88 to 1991/93) as 1-14 units/week and >14 units/week to reflect alcohol guidelines in the United Kingdom.18. By use of methodological enhancements of previous iterations,1 the systematic analysis from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2016 for 195 countries and territories, 1990-2016,2 is the most comprehensive estimate of the global burden of alcohol use to date. We first analysed the impact of potential differential misclassification on the hazard ratio estimate associated with abstinence compared with alcohol consumption of 1-14 units/week. Analysis using multistate models suggested that the excess risk of dementia associated with abstinence in midlife was partly explained by cardiometabolic disease over the follow-up as the hazard ratio of dementia in abstainers without cardiometabolic disease was 1.33 (0.88 to 2.02) compared with 1.47 (1.15 to 1.89) in the entire population. *Cox regression analysis adjusted for sociodemographic factors. Alcohol consumption trajectories from midlife to early old age supported these findingsboth long term abstainers and those reporting decreased alcohol consumption had an increased risk of dementia.

Medicine Family Practice. Participants in the 1-14 units/week alcohol consumption group were more likely to drink wine and those in the >14 units/week group to drink beer (table 1). The tendency to reduce alcohol consumption at older ages may bias results11 and prevent accurate analyses of the quantity of alcohol consumed.57 Thirdly, most studies use a single assessment of alcohol consumption, which is prone to measurement error. The aim of these analyses was to examine the association of long term alcohol consumption with risk of dementia using trajectories of alcohol consumption between 1985/88 and 2002/04 waves; the follow-up started in 2002/04 and covariates were drawn from the 2002/04 wave (or the closest wave if missing).

Publication types Meta-Analysis . The sponsors had no role in the design and conduct of the study; collection, management, analysis, and interpretation of the data; and preparation, review, or approval of this manuscript. Highly prevalent patterns of alcohol use may cause harm during these sensitive periods, including low level prenatal alcohol exposure, adolescent binge drinking, and low-to-moderate alcohol use in older adulthood.2 Although these patterns of alcohol exposure may be associated with less harm to individuals than sustained heavy drinking, the overall burden of harm in populations is likely to be large. Compared to those with a CAGE score of 0, a higher risk of dementia was observed in those with a CAGE score >2 (hazard ratio 2.19, 1.29 to 3.71). Repeat assessment of alcohol consumption allowed us to assess mean midlife alcohol consumption in order to minimise biases due to measurement error, examine associations with dementia of trajectories of alcohol consumption between midlife and early old age, and examine whether age modifies associations between alcohol consumption and dementia. Medicine. SS, AD, and ASM had full access to the data and take responsibility for the integrity of the data and the accuracy of the data analysis. Drinking guidelines: General population [updated January 2018]. This hazard ratio reduced to 3.0 (1.9 to 4.7) in fully adjusted analysis (table 2). Provenance and peer review: Commissioned; not externally reviewed. prenatal alcohol exposure was categorised according to the australian guide to the diagnosis of fasd 27 as: (i) no exposure, if there was confirmed absence of prenatal alcohol; (ii) confirmed exposure, if the audit-c score was 1-4, or there was confirmed use but the level of exposure was not known; (iii) confirmed high-risk exposure, if the Respected medical journal the British Medical Journal (BMJ) has reported on alleged data integrity issues with clinical trials that were carried out for Pfizer's Covid-19 vaccine. Is drinking a beer every day doing you more harm than good? Objectives. Our multistate models lent partial support for a mediating role of cardiometabolic disease in the association between alcohol abstention and increased risk of dementia; the hazard ratio of dementia associated with alcohol abstinence, compared with moderate consumption, was reduced to 1.33 (95% confidence interval 0.88 to 2.02) in those without cardiometabolic disease, compared with 1.47 (1.15 to 1.89) in the entire population. To assess the validity of the method of dementia ascertainment, we used a mixed model with a backward time scale and determined trajectories of global cognitive score based on performance in three cognitive domains (memory, reasoning, fluency), assessed five times between the 1997/99 and 2015/16 waves.25 These results show an accelerated decline in global cognition in the 10 years before the dementia diagnosis (appendix figure S2), as has been shown in studies that use a gold standard method for dementia ascertainment.26.

We converted measures on frequency and number of alcoholic drinks (measures of spirits, glasses of wine, and pints of beer) consumed to units of alcohol consumed per week.

Among those without cardiometabolic disease, compared with alcohol consumption of 1-14 units/week, the hazard ratio for dementia associated with abstinence was 1.33 (0.88 to 2.02) and with consumption >14 units/week was 1.28 (0.85 to 1.92) (fig 3); corresponding hazard ratios in the entire population, when cardiometabolic disease was not taken into consideration, were 1.47 (1.15 to 1.89) and 1.08 (0.82 to 1.43; table 2). Our journal collection includes some of the most influential titles in their field. This question is for testing whether or not you are a human visitor and to prevent automated spam submissions. Given the number of people living with dementia is expected to triple by 20503 and the absence of a cure, prevention is key.4 We show that both long term alcohol abstinence and excessive alcohol consumption may increase the risk of dementia. Multistate models (appendix figure S3) showed that these hazard ratios among participants without a dementia diagnosis during follow-up were reduced to 0.97 (0.67 to 1.41) and 1.10 (0.74 to 1.66), respectively, and the risk of mortality increased by 13% (7% to 19%) for each 7 unit increment among participants consuming >14 units/week. The report was based on information sent from a whistleblower that was backed up by others who worked on the trial. Observed first in studies of incidence of myocardial infarction,1 the J shaped curve (describing the graphical appearance of health measures plotted against consumption) reappears in studies of diabetes, stroke, and even chronic widespread pain.2 As methods of investigating the association between alcohol and health are refined, however, the size of the apparent benefits reduces substantially.3 Studies using Mendelian randomisation, purportedly impervious to confounding or reverse causality, do not support the original claim that moderate drinking improves cardiovascular health.4. Participants were censored at date of record of dementia, death, or 31 March 2017, whichever came first. Participants who reported consuming alcoholic beverages in the previous year but not in the last week at all three waves were classified as occasional drinkers (n=862, 9.5%). Flow chart of study.

This, in turn, can impact the ability of a breathalyzer test to accurately estimate blood alcohol levels of a driver . The global prevalence of alcohol use during pregnancy is estimated to be 9.8%, with an estimated prevalence of fetal alcohol syndrome in the general population of 14.6 per 10 000 people (Popova et al, 2017).There is an increasing focus on early intervention strategies to prevent potential long-term health problems, the root cause of which are often linked to lifestyle behaviours, and pregnancy . An American Journal of Clinical Nutrition article asserts that Vitamin D is far superior to vaccines at preventing the flu because it activates . We all use rationalisations to justify persistence with behaviours not in our long term interest. The present study has several strengths. In participants consuming >14 units/week (fig 4), cardiometabolic disease did not seem to play a role, as the hazard ratio associated with each increase of 7 units/week was 1.16 (0.96 to 1.41), similar to that observed when cardiometabolic diseases were not taken into account (1.17, 1.04 to 1.32; table 2). In addition, we examined whether cardiometabolic disease modifies the association between alcohol consumption and dementia. The models allow simultaneous estimation of the risk associated with alcohol consumption in three transitions: from healthy state to incident cardiometabolic disease, from cardiometabolic disease to incident dementia, and from healthy state to incident dementia in those free of cardiometabolic disease.

We used comprehensive tracing of electronic health records for dementia ascertainment based on three databases: the national hospital episode statistics, the Mental Health Services Data Set, and the mortality register. HR7 units/week associated with a 7 unit increase in alcohol consumption. british medical journal. 2 although these patterns of alcohol exposure may be associated with less harm to individuals than sustained heavy drinking, the All authors conceived and designed the study, analysed and interpreted the data, and drafted or critically revised the manuscript for important intellectual content, or, in addition, acquired data. Main outcome measures Incident dementia, identified through linkage to hospital, mental health services, and mortality registers until 2017. Alcohol dependence was measured by the CAGE questionnaire in 1991/93. MK is supported by NordForsk. Even this level of consumption carries risk relative to abstinence for conditions such as breast cancer, and the evidence of benefit is certainly not strong enough to justify advising abstainers to drink. Furthermore, a recent study based on a nationwide dataset of patients admitted to hospital in France between 2008 and 2013 reported that those with a hospital admission record for alcohol use disorders had a 3.3-times higher risk of dementia in multivariate analysis,12 providing further support for our findings. Appendix figure S4 shows the shape of the association between alcohol consumption in midlife and risk of dementia to be unaffected by the exclusion of the large group of abstainers from the analysis. In those reporting consumption of >14 units/week, we used spline regressions to examine whether there was a linear trend in the association of alcohol consumption with dementia and then estimated the risk of dementia for every increment of 7 units/week. Thirdly, multistate models showed that part of the excess risk of dementia in abstainers was attributable to the greater risk of cardiometabolic disease in this group. 2001 . We do not capture any email address. Among the 10231 participants alive in 1991/93, 9087 had at least two measurements of alcohol consumption between 1985/88 and 1991/93 and complete data on covariates (fig 1). The association between alcohol and mortality in healthy subjects has been described as a U-shaped or J-shaped curve in earlier studies. However, a conclusion with high-quality evidence of causality could not be easily drawn from regular observational studies. Besides measurement error, studies that recruit participants at older ages are not able to assess the excess risk in those who change their alcohol consumption with age. Trajectories were determined using group based trajectory modelling, fitted using the traj command in Stata.19 We chose the trajectories based on model fit statistics (bayesian information criterion values and average posterior probabilities) and judgment about whether they adequately addressed the research question (appendix table S3).20 The identified trajectories (appendix figure S1) were long term abstinence, decreased alcohol consumption, long term consumption of 1-14 units/week, increased consumption, and long term consumption of >14 units/week. We sought to estimate the incidence of myocarditis after mRNA vaccination against SARS-CoV-2, and to compare the incidence with expected rates based on historical background rates in British Columbia.
