BACKGROUND: Traumatic brain injury surveillance provides information for allocating resources to prevention efforts. Administrative data are widely available and inexpensive but may underestimate traumatic brain injury burden by misclassifying cases. Moreover, previous studies evaluating the accuracy of administrative data surveillance case definitions were at risk of bias by using imperfect diagnostic definitions as reference standards. We assessed the accuracy (sensitivity/specificity) of traumatic brain injury surveillance case definitions in administrative data, without using a reference standard, to estimate incidence accurately...

BACKGROUND: Being overweight constitutes a health risk, and the proportion of overweight and obese children is increasing. It has been argued that road traffic noise could be linked to adiposity through its influence on sleep and stress. Few studies, to our knowledge, have investigated whether noise and adiposity are associated. Most of them were on adults, and we are not aware of any longitudinal study using repeated measures. OBJECTIVES: The present longitudinal study investigated whether road traffic noise exposures in pregnancy (N=6,963; obs=22,975) or childhood (N=6,403; obs=14,585) were associated with body mass index (BMI) trajectories in children...

BACKGROUND: Exposure to air pollution during pregnancy may increase attention-deficit/ hyperactivity disorder (ADHD) symptoms in children, but findings have been inconsistent. We aimed to study this association in a collaborative study of eight European population-based birth/child cohorts, including 29,127 mother-child pairs. METHODS: Air pollution concentrations [nitrogen dioxide (NO2) and particulate matter (PM)] were estimated at the birth address by land-use regression models based on monitoring campaigns performed between 2008 and 2011...

Irene Man, Jacco Wallinga, Johannes A Bogaards
BACKGROUND: Many multi-valent vaccines target only a subset of all pathogenic types. If vaccine and non-vaccine types compete, vaccination may lead to type replacement. The plausibility of type replacement has been assessed using the odds ratio (OR) of co-infections in cross-sectional prevalence data, with OR > 1 being interpreted as low risk of type replacement. The usefulness of the OR as a predictor for type replacement is debated, as it lacks a theoretical justification, and there is no framework explaining under which assumptions the OR predicts type replacement...

BACKGROUND: Although congenital abnormalities in the male reproductive tract are common, their causes remain poorly understood. We studied associations between hypertensive disorders of pregnancy (pre-gestational hypertension, gestational hypertension, and preeclampsia) and the genital anomalies, cryptorchidism (undescended testes), and hypospadias (ventrally displaced urethral meatus). METHODS: We established a population of 1,073,026 Danish boys born alive between 1 January 1978 and 31 December 2012...

Kenneth J Rothman, Sander Greenland
Study size has typically been planned based on statistical power and therefore has been heavily influenced by the philosophy of statistical hypothesis testing. A worthwhile alternative is to plan study size based on precision, for example, by aiming to obtain a desired width of a confidence interval for the targeted effect. This paper presents formulas for planning the size of an epidemiologic study based on the desired precision of the basic epidemiologic effect measures.

BACKGROUND: Self-harm is a leading cause of morbidity and mortality. Exposure to community violence is an important and potentially modifiable feature of the social environment that may affect self-harm, but studies to date are limited in the samples and outcomes examined. METHODS: We conducted a population-based, nested case-control study. Cases were all deaths and hospital visits due to self-harm in California, 2006-2013. We frequency-matched California resident population-based controls from the American Community Survey to cases on age, gender, race/ethnicity, and year of survey/injury...

BACKGROUND: Community violence may affect a broad range of health outcomes through physiologic stress responses and changes in health behaviors among residents. However, existing research on the health impacts of community violence suffers from problems with bias. METHODS: We examined the relations of acute changes in community violence with hospital visits and deaths due to stress-responsive diseases (mental, respiratory, and cardiac conditions) in statewide data from California 2005-2013...

BACKGROUND: Exposure to ambient fine particulate matter (PM2.5) has been linked with premature mortality, but sources of PM2.5 have been less studied. METHODS: We evaluated associations between source-specific PM2.5 exposures and cause-specific short-term mortality in eight California locations from 2002-2011. Speciated PM2.5 measurements were source-apportioned using Positive Matrix Factorization into eight sources and combined with death certificate data. We utilized time-stratified case-crossover analysis with conditional logistic regression by location, and meta-analysis to calculate pooled estimates...
