Who gets screened and who tests positive? Drug screening among justice-involved youth in a midwestern urban county
Poverty, Comorbidity, and Ethnicity: Covid-19 Outcomes in a Safety Net Health System
Observed COVID-19 in-hospital mortality rate was lower than most published rates. Age, but not race-ethnicity, was independently correlated with in-hospital mortality. Safety net health systems are foundational in the care of vulnerable patients suffering from COVID-19, including patients from under-represented and low-income groups
The role of partner gender in bisexual men’s stigma-related experiences and mental health: Results from a probability-based sample in the United States
Bisexual men are disproportionately affected by negative mental health outcomes compared to heterosexual and gay men. These disparities are related to the unique stressors that they experience, and emerging evidence suggests that their experiences of these stressors can be different depending on the gender of their partner. However, previous studies have largely focused on bisexual women and little is known about the role of partner gender in bis…
The point of diminishing returns in juvenile probation: Probation requirements and risk of technical probation violations among first-time probation-involved youth
Technical probation violations are common among probation-involved youth, and across many jurisdictions, may result in detention or residential placement. The current study examined prevalence of technical violations occurring during one's first probation period, the average time to technical violation, and individual-level and justice-related factors related to technical violations among probation-involved youth in a juvenile justice system. We …
Sex and Race Differences in the Relationship between Obesity and C-Reactive Protein
C-reactive protein (CRP) is a risk factor for cardiovascular disease and mortality; it is known to be positively associated with obesity but there is some evidence that this association differs by race or sex. We used nationally representative data of adults aged >50 years to investigate sex and race modifiers of the associations between obesity and CRP in non-Hispanic White males (n=3,517) and females (n=4,658), and non-Hispanic Black males (n=4…
Optimizing strategies for population-based chlamydia infection screening among young women: An age-structured system dynamics approach
Our research demonstrates the potential economic benefit of age-dependent screening strategy design for population-based screening programs. It also showcases the applicability of age-structured system dynamical modeling to infectious disease control with increasing evidence on the age differences in infection risk. The research can be further improved with consideration of the difference between first-time infection and reinfection, as well as p…
Comprehensive Evaluation of Caregiver-Reported Antiretroviral Therapy Adherence for HIV-Infected Children
Age Differences in the Association Between Body Mass Index Class and Annualized Medicare Expenditures
Excess Medicare expenditures related to obesity may be concentrated among severely obese young-old adults. Preventing severe obesity among middle and older aged adults may have large cost implications for society
Impact of Dementia on Payments for Long-term and Acute Care in an Elderly Cohort
BACKGROUND: Older people with dementia have increased risk of nursing home (NH) use and higher Medicaid payments. Dementia's impact on acute care use and Medicare payments is less well understood. OBJECTIVES: Identify trajectories of incident dementia and NH use, and compare Medicare and Medicaid payments for persons having different trajectories. RESEARCH DESIGN: Retrospective cohort of older patients who were screened for dementia in 2000-2004 …
Predictors of Cancer-Related Pain Improvement Over Time
Objective To determine the predictors of pain improvement among patients being treated for cancer-related pain over 12 months. Methods A secondary analysis of the telephone care Indiana Cancer Pain and Depression trial was performed. Patients (n = 274) were interviewed at baseline and after 1, 3, 6, and 12 months. Pain improvement outcomes included both a continuous measure (Brief Pain Inventory score) and a categorical measure (pain improved ver…
A Comparison and Cross-validation of Models to Predict Basic Activity of Daily Living Dependency in Older Adults
BACKGROUND: A simple method of identifying elders at high risk for activity of daily living (ADL) dependence could facilitate essential research and implementation of cost-effective clinical care programs. OBJECTIVE: We used a nationally representative sample of 9446 older adults free from ADL dependence in 2006 to develop simple models for predicting ADL dependence at 2008 follow-up and to compare the models to the most predictive published mode…
Characteristics Associated with Sex After Periods Of Abstinence Among Sexually Experienced Young Women
To provide targeted and timely sexual health counseling, clinicians may want to ask adolescents not only whether they are sexually active but also when they last had sex
Comparative Responsiveness of Pain Outcome Measures Among Primary Care Patients With Musculoskeletal Pain
BACKGROUND: Comparative responsiveness data are needed to inform choices about pain outcome measures. OBJECTIVES: To compare responsiveness of pain intensity, pain-related function, and composite measures, using data from a randomized trial and observational study. RESEARCH DESIGN: Analysis of responsiveness. SUBJECTS: A total of 427 adults with persistent back, hip, or knee pain were recruited from primary care. METHODS: Participants completed B…
The Influence of Hormonal Contraception on Mood and Sexual Interest among Adolescents
Condom Use as a Function of Time in New and Established Adolescent Sexual Relationships
Objectives. This study sought to describe condom use over time in new and established adolescent relationships. Methods. The outcome variable was time (in days) until first unprotected coital event. Analyses involved comparisons of Kaplan–Meier survival curves and Cox proportional hazards models. Results. Survival functions for the 2 relationship groups were significantly different. However, by 21 days the curves had converged: 43% of new and 41%…
