Although heterogeneity in the timing and persistence of maternal depressive symptomatology has implications for screening and treatment as well as associated maternal and child health outcomes, little is known about this variability. A prospective observational study of 1,735 low-income, multiethnic, inner-city women recruited in pregnancy from 2000 to 2002(More)
OBJECTIVE This study examined whether pregnancy is associated with discontinuation of care for depression among low-income women. METHODS Medicaid claims data from all 50 states were used in a matched cohort study design. The study included 3,237 women who gave birth between 1999 and 2000 and received depression treatment (antidepressant medications or a(More)
Mature natural killer (NK) cells use Ca2+-dependent granule exocytosis and release of cytotoxic proteins, Fas ligand (FasL), and membrane-bound or secreted cytokines (tumor necrosis factor [TNF]-alpha) to induce target cell death. Fas belongs to the TNF receptor family of molecules, containing a conserved intracytoplasmic "death domain" that indirectly(More)
BACKGROUND Postpartum physical health problems are common and have been understudied. The purpose of this investigation was to explore the associations among reported physical symptoms, functional limitations, and emotional well-being of postpartum women. METHODS The study included data from interviews conducted at 9 to 12 months postpartum from 1,323(More)
Cytokine-mediated enhancement of spontaneous cytotoxicity depends, at least in part, on modulation of the expression of surface molecules responsible for recognition of target cell structures and triggering or inhibition of the cytotoxic machinery. We previously demonstrated that expression of transcription factors (e.g., Egr-1, JunB, and c-Fos) is(More)
To assess understanding of numerical concepts in asthma self-management instructions, a 4-item Asthma Numeracy Questionnaire (ANQ) was developed and read to 73 adults with persistent asthma. Participants completed the Short Test of Functional Health Literacy in Adults (STOFHLA), 12(16%) answered all 4 numeracy items correctly; 6(8%) answered none correctly.(More)
PURPOSE Health literacy is associated with a range of poor health-related outcomes. Evidence that health literacy contributes to disparities in health is minimal and based on brief screening instruments that have limited ability to assess health literacy. The purpose of this study was to assess whether health literacy contributes, through mediation, to(More)
OBJECTIVE Systems for efficient case finding of women with major depression during pregnancy and postpartum are needed. Here we assess the diagnostic accuracy of a modified 2-item patient health questionnaire (PHQ-2) as a pre-screen in assessing depression. METHODS Cross-sectional assessments at 15 weeks' gestation (n = 414), 30 weeks' gestation (n =(More)
Identifying modifiable barriers to antiretroviral adherence remains an important aim. We hypothesized that mistaken beliefs regarding taking HIV medications mediated the relation between low literacy and poor adherence. We studied 87 HIV-infected individuals on standard antiretroviral regimens for ≥ 3 months. Adherence was assessed using pharmacy refill(More)
OBJECTIVE The purpose of this study was to assess the contribution of depressive symptoms and poor contraceptive use early in the first postpartum year to the risk of unintended repeat pregnancy at the end of that year among adults with low educational status (< 12th grade or equivalence). STUDY DESIGN This was a prospective observational cohort study of(More)
