Aspirin has public health potential to reduce the risk of ischaemic vascular events and sporadic cancer. One objection to the wider use of aspirin for primary prevention, however, is the undesirable effects of the medicine, which include increasing risk of bleeding and haemorrhagic stroke. Marathons also carry risks of serious events such as…

While there is a growing interest in conducting qualitative research in military settings, there are few published studies which provide strategies for working with this unique population. [Our program] has conducted 437 focus groups (n=3,160) between 2008 and 2014. Through our extensive field experience with this population, we have observed how…

Ferguson, like many at-risk suburbs, has largely been lost in discussions of the geography of opportunity. The authors conducted a descriptive epidemiological case study of Ferguson and its surrounding region with a focus on health and education indicators. Drawing from a variety of community data sources, they used geospatial methods to…

The purpose of the present study was to re-examine diagnostic data from a state-wide autism prevalence study (n = 489) conducted in the 1980s to investigate the impact of broader diagnostic criteria on autism spectrum disorder (ASD) case status. Sixty-four (59%) of the 108 originally "Diagnosed Not Autistic" met the current ASD case definition.…

Background: Marijuana represents the most widely used illicit drug on college campuses. Repeated use can impair students' academic, emotional, and physical success and can lead to chronic diseases. Purpose: The purpose of this study was to evaluate existing literature on the associated effects of marijuana use on U.S. college students' academic…

To evaluate risk of suicide of women with invasive gynecologic malignancies, the National Cancer Institute's Surveillance, Epidemiology, and End Results Program (1973-2007) was queried. Suicide per 100,000 women with gynecologic malignancies was compared with that of women with other malignancies; suicide was 30% more likely in those with…

This essay describes briefly population neuroscience, the merging of genetics and epidemiology with neuroscience, and its goals with regard to (1) gaining new knowledge about "processes" leading to a particular "state" of brain structure and function, and (2) using this knowledge to predict the risk (and resilience) of an…

Current research shows that geo-political units (e.g., the 50 U.S. states) vary meaningfully on psychological dimensions like intelligence (IQ) and neuroticism (N). A new scientific discipline has also emerged, differential epidemiology, focused on how psychological variables affect health. We integrate these areas by reporting large correlations…

High-intensity interval training (HIIT) has garnered attention in recent years as a time-efficient exercise option for improving cardiovascular and metabolic health. New research demonstrates that HIIT may be particularly effective for improving postprandial hyperglycemia in individuals with, or at risk for, type 2 diabetes (T2D). These findings…

Two-phase designs in epidemiological studies of autism prevalence introduce methodological complications that can severely limit the precision of resulting estimates. If the assumptions used to derive the prevalence estimate are invalid or if the uncertainty surrounding these assumptions is not properly accounted for in the statistical inference…

In this article, Marianne Cutler and Liz Lawrence describe in more detail the opportunities for "working scientifically" provided by this new Association for Science Education (ASE) resource, which was introduced in the previous issue, along with some of the feedback from teachers who have trialled the resources. [This article was…

This study examines historical variation in age 18 to 26 binge drinking trajectories, focusing on differences in both levels of use and rates of change (growth) across cohorts of young adults over 3 decades. As part of the national Monitoring the Future Study, over 64,000 youths from the high school classes of 1976 to 2004 were surveyed at…

In many control systems changes in the dynamics occur unexpectedly or are applied by a controller as needed. The time at which a controller implements changes is not necessarily known a priori. For example, many manufacturing systems and flight operations have complicated control systems, and changes in the control systems may be automatically…

Each year, the Interagency Autism Coordinating Committee (IACC) releases a list of scientific advances that represent significant progress in the field. The "2020 Summary of Advances in Autism Research" provides short, plain language summaries of the top research breakthroughs selected by the IACC from a pool of research articles…

Seasonality analyses are important in medical research. If the incidence of a disease shows a seasonal pattern, then an environmental factor must be considered in its etiology. We discuss a method for the simultaneous analysis of seasonal variation in multiple groups. The nuts and bolts are explained using simple trigonometry, an elementary…
