Emergency Department Utilization by Women of Reproductive Age for Mental Illness in St. Louis Before and During the Covid-19 Pandemic
Mental illness and related health inequities are disproportionately concentrated in economically disadvantaged urban neighborhoods. The COVID-19 pandemic has been associated with a rise in mental illness prevalence, with women generally at greater risk than men. Urban areas facing multiple structural and socioeconomic challenges may have limited capacity to meet the mental healthcare needs of residents, leading to increased reliance on emergency …

Resilience buffers the effects of sleep problems on the trajectory of suicidal ideation from adolescence through young adulthood
Changes in Body Mass Index and the Trajectory of Depressive Symptoms Among Rural Men and Women
PURPOSE: This study examined the association between body mass index (BMI) changes over time and the risk of elevated depressive symptoms in a cohort of Midwestern rural adults. METHODS: The longitudinal study used data from a telephone survey in 2005 including 1,475 men and women enrolled in the Walk the Ozarks to Wellness Project from 12 rural communities in Missouri, Arkansas, and Tennessee. Multilevel random intercept mixed models were used t…
The Effects of Race and Ethnicity on the Risk of Large-for-Gestational-Age Newborns in Women Without Gestational Diabetes by Prepregnancy Body Mass Index Categories
Racial/Ethnic Differences in the Correlates of Mental Health Services Use among Pregnant Women with Depressive Symptoms
Association Between Physical Activity and Insomnia Symptoms in Rural Communities of Southeastern Missouri, Tennessee, and Arkansas
PURPOSE: The purpose of this study is to examine whether physical activity is associated with less insomnia symptoms in the rural communities. METHODS: This study used cross-sectional data collected from a 2005 telephone survey for evaluation of a community walking trails intervention to promote physical activity in rural communities including 6 communities in the Missouri Ozark region and 6 communities in Arkansas and Tennessee (n = 1,234). The …
The Association of Sleep Duration and Depressive Symptoms in Rural Communities of Missouri, Tennessee, and Arkansas
Purpose: To determine the association between sleep duration and depressive symptoms in a rural setting. Methods: We conducted a cross‐sectional study using data from Wave 3 of the Walk the Ozarks to Wellness Project including 12 rural communities in Missouri, Arkansas, and Tennessee (N = 1,204). Sleep duration was defined based on average weeknight and weekend hours per day: short ( 8). The primary outcome was self‐reported elevated depressive s…
Does a Medical Home Influence the Effect of Low Birthweight on Health Outcomes
Does Gestational Weight Gain Affect the Risk of Adverse Maternal and Infant Outcomes in Overweight Women
Child Maltreatment in the United States
OBJECTIVES. The purpose of this study was to estimate the prevalence of child maltreatment in the United States and examine its relationship to sociodemographic factors and major adolescent health risks. METHODS. The National Longitudinal Study of Adolescent Health is a prospective cohort study following a national sample of adolescents into adulthood. The wave III interview, completed by 15 197 young adults in 2001–2002 (77.4% response rate), in…
Profit Sharing, Risk Sharing, and Firm Size
Measuring the Environment for Friendliness Toward Physical Activity
Objectives. We tested the reliability of 3 instruments that assessed social and physical environments. Methods. We conducted a test–retest study among US adults (n = 289). We used telephone survey methods to measure suitableness of the perceived (vs objective) environment for recreational physical activity and nonmotorized transportation. Results. Most questions in our surveys that attempted to measure specific characteristics of the built enviro…
Worker Productivity, Working Time Reduction, And The Short–Run And Long–Run Employment Effects
This paper illustrates a shirking–type efficiency wage model to explain why shorter working hours cause an ambiguous effect on employment as the empirical result. We find that shorter working hours have an uncertain impact on the work effort, and the relationship between work effort and shorter working time is a decisive factor in the employment effect of working time reduction. Moreover, it is also found that, given the zero profit constraint, t…
A Dynamic Model of Union Membership and Employment
This paper re‐examines the dynamic features and the long‐run effects of raising interest rates on union membership and employment in the Jones–McKenna (1994) model. Two major findings emerge from the analysis. First, the dynamic system of Jones and McKenna’s model exhibits saddlepoint stability, rather than global stability. Second, when the economy experiences a rise in interest rate, union membership will eventually converge to a higher level
