Big Data has increasingly been promoted as a revolutionary development in the future of science, including epidemiology. However, definition and implications for epidemiology remain unclear. We here provide working predicated on so-called "three V's": variety, volume, velocity. From this definition, we argue that evolutionary identifying intervening determinants population health. suggest more sources diverse data become publicly available, ability to combine refine these yield valid answers...
Phthalate exposures are hypothesized to increase obesity; however, prior research has been largely cross-sectional.We evaluated associations between prenatal phthalate and body mass index (BMI) at child ages 5 7 years.Nine metabolites of six phthalates-di(2-ethylhexyl) (DEHP), di-n-octyl-, di-iso-butyl-, di-n-butyl-, butylbenzyl-, diethyl phthalates-were measured in spot urine samples collected from pregnant African-American Dominican women during their third trimester, children 3 years. To...
Research has been limited on the incidence, mechanisms, etiology, and treatment of symptoms that require palliation in patients with terminal cancer. Bowel obstruction (BO) is a common complication advanced abdominal cancer, including colon for which small, single-institution studies have suggested an incidence rate 15% to 29%. Large population-based examining or risk factors associated BO cancer are lacking.To investigate stage IV cancer.Retrospective cohort, study Surveillance,...
Neighborhood physical disorder is thought to affect mental and health, but it has been difficult measure objectively reliably across large geographical areas or multiple locales. Virtual street audits are a novel method for assessing neighborhood characteristics. We evaluated the ecometric properties of constructed from virtual audit data. Eleven trained auditors assessed 9 previously validated items developed capture (e.g., litter, graffiti, abandoned buildings) on 1,826 block faces using...
Objectives. To demonstrate an information technology–based approach to assess characteristics of streets and intersections associated with injuries that is less costly time-consuming than location-based studies pedestrian injury. Methods. We used imagery captured by Google Street View from 2007 2011 9 532 within New York City. controlled for estimated count the relation between intersections’ frequency injurious collisions. Results. The at was presence marked crosswalks (80% increase; 95%...
Poverty is an important predictor of child maltreatment. Social policies that strengthen the economic security low-income families, such as Earned Income Tax Credit (EITC), may reduce maltreatment by impeding pathways through which poverty leads to it. We used variations in presence and generosity supplementary EITCs offered at state level administrative data from National Child Abuse Neglect Data System (NCANDS) examine effect EITC on state-level rates 2004 2017. Two-way fixed effects...
In-person audits to collect data on neighborhood characteristics offer opportunities study the mechanisms that link conditions unequal outcomes for individuals and communities, but expense logistical difficulties associated with conducting have limited their use. The images collected by Google Street View provide a promising alternative researchers measure environments across cities examine how vary wider geographic scope. We describe benefits of using “virtual” discuss practicalities...
Importance The absence of reliable hospital discharge data regarding the intent firearm injuries (ie, whether caused by assault, accident, self-harm, legal intervention, or an act unknown intent) has been characterized as a glaring gap in US firearms infrastructure. Objective To use incident-level information to assess accuracy coding used for injury surveillance. Design, Setting, and Participants This cross-sectional retrospective medical review study was conducted using case-level from 3...
Importance Sweetened beverage taxes have been associated with reduced purchasing of taxed beverages. However, few studies assessed the association between sweetened and health outcomes. Objective To evaluate Seattle tax change in body mass index (BMI) among children. Design, Setting, Participants In this longitudinal cohort study, anthropometric data were obtained from electronic medical records 2 care systems (Kaiser Permanente Washington [KP] Children’s Hospital Odessa Brown Clinic...
Background/Objectives: physical activity may be beneficial in reducing depression incidence among the elderly. A key unanswered question is whether certain types of are particularly associated with decreased incidence. We examined relationship between quantity and type subsequent using longitudinal data from elderly adults New York City (NYC). Methods: we followed 3,497 aged 65–75 living NYC for three years. Total was measured Physical Activity Scale Elderly (PASE) a latent class analysis...
Neighborhood conditions may influence a broad range of health indicators, including obesity, injury, and psychopathology. In particular, neighborhood physical disorder-a measure urban deterioration-is thought to encourage crime high-risk behaviors, leading poor mental health. studies assess disorder, investigators typically rely on time-consuming expensive in-person systematic audits. We compared 2 audit-based measures disorder in the city Detroit, Michigan: One used Google Street View...
Abstract Virtual audits using Google Street View are an increasingly popular method of assessing neighborhood environments for health and urban planning research. However, the validity these studies may be threatened by issues image availability, age, variance particularly in Global South. This study identifies patterns age across cities Latin America assesses relationships between measures resident socioeconomic conditions. Image availability was assessed at 530,308 near-road points within...
OBJECTIVES Poverty and low income are associated with increased risk for child maltreatment. The Earned Income Tax Credit (EITC) Child (CTC) among the largest antipoverty programs in United States. We estimated associations between transfer payments via EITC CTC maltreatment reports period shortly after families receive from these programs. METHODS linked weekly refund data Internal Revenue Service to state-specific report 48 states District of Columbia during 2015 through 2018 tax seasons...
International Classification of Diseases-coded hospital discharge data do not accurately reflect whether firearm injuries were caused by assault, unintentional injury, self-harm, legal intervention, or undetermined intent. Applying natural language processing (NLP) and machine learning (ML) techniques to electronic health record (EHR) narrative text could be associated with improved accuracy injury intent data.To assess the which an ML model identified intent.A cross-sectional retrospective...
ABSTRACT Distributed lag models (DLMs) estimate the health effects of exposure over multiple time lags prior to outcome and are widely used in series studies. Applying DLMs retrospective cohort studies is challenging due inconsistent lengths history across participants, which common when using electronic record databases. A standard approach define subcohorts individuals with some minimum history, but this limits power may amplify selection bias. We propose alternative full-cohort methods...
Abstract Background: Observed neighborhood disinvestment is a chronic social determinant that understudied in relation to cancer outcomes. This study investigated associations between disinvestment, stage at diagnosis, and breast cancer-specific survival time. Methods: Individual-level data included 844 women, diagnosed 2013-2019, from the Women’s Circle of Health Follow-up Study, population-based cohort survivors self-identifying as Black or African American. Neighborhood was virtual audit...
