New-Onset Asthma and Combat Deployment: Findings From the Millennium Cohort Study.
This study aimed to longitudinally determine the risk factors for developing asthma, including combat deployment (categorized as deployed with combat experience, deployed without combat experience, and nondeployed), among Millennium Cohort Study participants from 2001 to 2013. A total of 75,770 participants completed a baseline and at least one triennial follow-up survey on deployment experiences, lifestyle characteristics, and health outcomes. Complementary log-log models stratified by sex were used to estimate the relative risk of developing asthma among participants who reported no history of asthma at baseline. In adju...

Associations of Tipped and Untipped Service Work with Poor Mental Health in a Nationally Representative Cohort of Adolescents Followed into Adulthood.
Abstract Precarious work is concentrated in the service industry in the United States and is a risk factor for poor mental health. Service occupations in which workers receive tips are potentially more precarious due to unstable schedule, income, and lack of benefits. We tested hypotheses that individuals working in tipped service occupations have greater odds of experiencing poor mental health (self-reported depression, sleep problems, and/or greater perceived stress) relative to individuals in untipped service and non-service occupations using cross-sectional data from the National Longitudinal study of Adolesce...

Prenatal Exposure to Antibiotics and Risk of Childhood Obesity in a Multi-Center Cohort Study.
Abstract Mounting evidence has linked postnatal antibiotic use with body mass index (BMI) in children, but the influence of prenatal antibiotic use on offspring obesity risk remains unclear. We aimed to assess the association between fetal exposure to antibiotics and obesity at ages 4 and 7 years among 43,332 children using a multi-center prospective cohort of the U.S. Collaborative Perinatal Project (1959-1976). Antibiotic use was ascertained for mothers during pregnancy. Modified Poisson regression models were used to estimate risk ratios (RRs) of obesity (BMI > 95th percentile) and linear mixed mod...

Revealing Measles Outbreak Risk With a Nested IgG Serosurvey in Madagascar.
ud JM Abstract Madagascar reports few measles cases annually and high vaccination campaign coverage. However, the underlying age profile of immunity and risk of a measles outbreak is unknown. We conducted a nested serological survey, testing 1,005 serum collected between November 2013 and December 2015 via Madagascar's febrile rash surveillance system, for measles immunoglobulin G antibody titers. We directly estimated the age profile of immunity and compared these estimates to indirect estimates based on a birth cohort model of vaccination coverage and natural infection. Combining these estimates of the age profi...

Biomarker-Calibrated Total Sugars Intake and Risk of Type 2 Diabetes and Cardiovascular Disease in the Women's Health Initiative Observational Study.
Abstract The inconsistent findings from epidemiologic studies relating total sugars (TS) consumption to cardiovascular disease (CVD) or type 2 diabetes (T2D) risk may be partly due to measurement error (ME) in self-reported intake. Using regression calibration equations developed based on the predictive biomarker for TS and recovery biomarker for energy, we examined the association of TS with T2D and CVD risk, before and after dietary calibration, in 82,254 postmenopausal women of the Women's Health Initiative-Observational Study. After up to 16 years of follow-up (1993-2010), 6,621 T2D and 5,802 CVD incident case...

Abstract The self-controlled tree-temporal scan statistic-a new signal-detection method-can evaluate whether any of a wide variety of health outcomes are temporally associated with receipt of a specific vaccine, while adjusting for multiple testing. Neither health outcomes nor postvaccination potential periods of increased risk need be prespecified.

Invited Commentary: Moving From Evidence to Impact for Human Papillomavirus Vaccination-The Critical Role of Translation and Communication in Epidemiology.
Abstract In response to the accompanying article by Yih et al. (Am J Epidemiol. 2018;187(6):1269-1276), we highlight the importance of moving beyond epidemiologic research on human papillomavirus (HPV) vaccine safety to focus on translation of this strong evidence base into successful vaccine safety communication strategies to bolster vaccine uptake. The potential of the HPV vaccine to reduce cancer incidence is substantial, yet actual HPV vaccination rates in the United States are disappointingly low in comparison with other routine childhood vaccines with similar safety profiles. This is no doubt due, in part, t...

Associations of Circulating 25-Hydroxyvitamin D3 Concentrations With Incident, Sporadic Colorectal Adenoma Risk According to Common Vitamin D Binding Protein Isoforms.
Abstract 25-hydroxyvitamin D3 (25[OH]D3), the main circulating form of vitamin D, is inversely associated with incident, sporadic colorectal adenoma. We investigated whether this association differs by two functional variants in the vitamin D binding protein gene (group-specific component, GC) that encode for common protein isoforms (Gc1s, Gc1f, Gc2) linked to differences in vitamin D metabolism. We pooled data (418 adenoma cases, 524 polyp-free controls) from three colonoscopy-based case-control studies (Minnesota, 1991-1994; North Carolina, 1994-1997; South Carolina, 2002).

Identification of Chronic Obstructive Pulmonary Disease Axes That Predict All-Cause Mortality: The COPDGene Study.
vestigators Abstract Chronic Obstructive Pulmonary Disease (COPD) is a syndrome caused by damage to the lungs resulting in decreased pulmonary function and reduced structural integrity. Pulmonary function testing (PFT) is currently used to diagnose and stratify COPD into severity groups and chest computed tomography (CT) imaging is often used to assess structural changes in the lungs. We hypothesized that the combination of PFT and CT phenotypes would provide a more powerful tool for assessing underlying morphologic differences associated with pulmonary function in COPD than PFT alone. We used factor analysis of 2...

Abstract Recent work demonstrated that propensity score matching may lead to increased covariate imbalance, even with the corresponding decrease in propensity score distance between matched units. The extent to which this paradoxical phenomenon might harm causal inference in real epidemiologic studies has not been explored. We evaluated the effect of this phenomenon using insurance claims data from the Pharmaceutical Assistance Contract for the Elderly (1999-2002) and Medicaid Analytic eXtract (2000-2007) databases. For each dataset, we created several 1:1 propensity score-matched datasets by manipulating the size...

Cluster Randomized Test-Negative Design (CR-TND) Trials: A Novel and Efficient Method to Assess the Efficacy of Community Level Dengue Interventions.
We describe a novel cluster randomized trial methodology with a test-negative design, which offers advantages over traditional approaches. It utilizes outcome-based sampling of patients presenting with a syndrome consistent with the disease of interest, who are subsequently classified as test-positive cases or test-negative controls on the basis of diagnostic testing. We use simulations of a cluster trial to demonstrate validity of efficacy estimates under the test-negative approach. This demonstrates that, provided study arms are balanced for both test-negative and test-positive illness at baseline and that other test-neg...

Ramadan, Pregnancy, Nutrition, and Epidemiology.
Abstract Ramadan is observed by 1.6 billion Muslims. In a paper published this month that uses data from the Nouna Health and Demographic Surveillance System site in Burkina Faso, it is found that experiencing Ramadan in early pregnancy is associated with an increased risk of child mortality. Ramadan exposes observant individuals to a specific pattern of nutrition and other behaviors, including changes in sleep patterns. How these behaviors might result in child mortality is not yet understood, and the findings reported in the paper should be replicated in other settings. PMID: 29741561 [PubMed - as supplied ...

A Matter of Survival: The Detrimental Consequences of Adverse Early Life Conditions.
Abstract Studies across different species have shown that moderate dietary restriction is associated with longer lifespan. Surprisingly however, when diet is restricted in prenatal life, the effect is completely the opposite. Animal work and human epidemiologic data have shown that undernutrition in utero negatively affects health in later life and reduces lifespan considerably. In this issue of the American Journal of Epidemiology, Schoeps et al. provide new evidence that variations in nutritional conditions during pregnancy relate to the future health of the unborn child (1). In a detailed analysis of data from ...

Ramadan Exposure In utero and Child Mortality in Burkina Faso: Analysis of a Population-Based Cohort Including 41,025 Children.
te; A, Gabrysch S Abstract Ramadan exposure in utero can be regarded as a natural experiment to study how nutritional conditions in utero influence susceptibility to disease later in life. We analyzed data from rural Burkina Faso on 41,025 children born between 1993 and 2012, of which 25,093 to Muslim mothers. Ramadan exposure was assigned based on overlap between Ramadan dates and gestation, creating seven exclusive categories. We used proportional hazards regression with difference-in-differences to estimate the association between Ramadan exposure at different gestational ages and under-five mortality. Under-fi...

Medical History, Medication Use, and Risk of Nasopharyngeal Carcinoma.
Abstract Because persistent inflammation may render the nasopharyngeal mucosa susceptible to carcinogenesis, chronic ear/nose/throat (ENT) disease and its treatment might influence the risk of nasopharyngeal carcinoma (NPC). Existing evidence is, however, inconclusive and often based on methodologically suboptimal epidemiologic studies. In a population-based case-control study in southern China, we enrolled 2532 NPC cases and 2597 controls aged 20-74 years from 2010 to 2014. Odds ratios were estimated for associations between NPC risk and history of ENT and related medications. Any history of chronic ENT disease w...

Measurement of Current Substance Use in a Cohort of HIV-infected Persons in Continuity HIV Care, 2007-2015.
Abstract Accurate, routine measurement of recent illicit substance use is challenging. The Johns Hopkins Human Immunodeficiency Virus Clinical Cohort (Baltimore, MD) collects two imperfect but routine measurements of recent substance use: medical record review and self-interview. We used Bayesian latent class modeling to estimate sensitivity and specificity of each measurement, and prevalence of substance use among 2,064 patients engaged in care from 2007 to 2015. Sensitivity of medical record review was higher than sensitivity of self-interview for cocaine and heroin use; posterior estimates ranged from 44% to 76...
