Socioeconomic and racial/ethnic disparities in postpartum consultation for mental health concerns among US mothers.

Limited research has examined factors that impact access to postpartum mental healthcare. We investigated the predisposing, enabling, and need factors associated with postpartum consultation for mental health concerns in US mothers with or without depressive symptoms and examined potential disparities in access. We utilized cross-sectional data from the Listening to Mothers II Survey, the second national US survey of women's childbearing experiences. The survey recruited 1573 women, aged 18-45 years, who spoke English and had given birth. Depressive symptoms were measured with the Postpartum Depression Screening Scale (PDSS-SF). The dependent variable was postpartum consultation for mental health concerns. Logistic regression analyses showed that mothers with scores of 14-21 and 22-35 on the PDSS-SF had higher odds of consulting a provider for mental health concerns (OR 3.97; OR 12.91). Latinas had lower odds of seeking mental health consultations than Whites (OR 0.39). Mothers who were employed prenatally full-time or part-time had lower odds of seeking consultations than non-employed mothers (OR 0.62; OR 0.52). Mothers with household incomes of $50,000-$74,999 had higher odds of seeking consultations than those with incomes less than $25,000 (OR 2.20). When regression analyses were restricted to mothers with PDSS-SF scores ≥ 14, findings were similar by race/ethnicity and prenatal employment. Significant depressive symptoms are common in women after giving birth and few sought any form of mental health consultation. Latinas and low-income women are less likely to seek postpartum mental health consultations. Mental health care interventions could be geared towards targeting these at-risk groups.

Developmental trajectories of brain volume abnormalities in children and adolescents with attention-deficit/hyperactivity disorder.

CONTEXT: Various anatomic brain abnormalities have been reported for attention-deficit/hyperactivity disorder (ADHD), with varying methods, small samples, cross-sectional designs, and without accounting for stimulant drug exposure. OBJECTIVE: To compare regional brain volumes at initial scan and their change over time in medicated and previously unmedicated male and female patients with ADHD and healthy controls. DESIGN, SETTING, AND PARTICIPANTS: Case-control study conducted from 1991-2001 at the National Institute of Mental Health, Bethesda, Md, of 152 children and adolescents with ADHD (age range, 5-18 years) and 139 age- and sex-matched controls (age range, 4.5-19 years) recruited from the local community, who contributed 544 anatomic magnetic resonance images. MAIN OUTCOME MEASURES: Using completely automated methods, initial volumes and prospective age-related changes of total cerebrum, cerebellum, gray and white matter for the 4 major lobes, and caudate nucleus of the brain were compared in patients and controls. RESULTS: On initial scan, patients with ADHD had significantly smaller brain volumes in all regions, even after adjustment for significant covariates. This global difference was reflected in smaller total cerebral volumes (-3.2%, adjusted F(1,280) = 8.30, P =.004) and in significantly smaller cerebellar volumes (-3.5%, adjusted F(1,280) = 12.29, P =.001). Compared with controls, previously unmedicated children with ADHD demonstrated significantly smaller total cerebral volumes (overall F(2,288) = 6.65; all pairwise comparisons Bonferroni corrected, -5.8%; P =.002) and cerebellar volumes (-6.2%, F( 2,288) = 8.97, P<.001). Unmedicated children with ADHD also exhibited strikingly smaller total white matter volumes (F(2,288) = 11.65) compared with controls (-10.7%, P<.001) and with medicated children with ADHD (-8.9%, P<.001). Volumetric abnormalities persisted with age in total and regional cerebral measures (P =.002) and in the cerebellum (P =.003). Caudate nucleus volumes were initially abnormal for patients with ADHD (P =.05), but diagnostic differences disappeared as caudate volumes decreased for patients and controls during adolescence. Results were comparable for male and female patients on all measures. Frontal and temporal gray matter, caudate, and cerebellar volumes correlated significantly with parent- and clinician-rated severity measures within the ADHD sample (Pearson coefficients between -0.16 and -0.26; all P values were <.05). CONCLUSIONS: Developmental trajectories for all structures, except caudate, remain roughly parallel for patients and controls during childhood and adolescence, suggesting that genetic and/or early environmental influences on brain development in ADHD are fixed, nonprogressive, and unrelated to stimulant treatment.

Cytogenetic abnormalities in attention-deficit/hyperactivity disorder.

OBJECTIVE: To systematically assess the prevalence of fragile X syndrome, velocardiofacial syndrome, and other cytogenetic abnormalities in a group of children with attention-defict/hyperactivity disorder (ADHD). METHOD: Blood samples were obtained from 100 children (64 boys) with combined type ADHD and normal intelligence and analyzed for the presence of fragile X mutation expansions, the 22q11.2 microdeletion associated with velocardiofacial syndrome, and cytogenetic abnormalities that would be detected with high resolution chromosomal banding. RESULTS: One girl with ADHD had a sex chromosome aneuploidy (47,XXX). One boy had a premutation-sized allele for fragile X; no subjects showed the full mutation. Testing for 22q11.2 microdeletion was negative for all subjects with ADHD screened. None of these differences exceeded those expected by chance. CONCLUSIONS: In the absence of clinical signs or positive family history, these relatively expensive laboratory assessments are not clinically indicated for children with ADHD and normal intelligence, and are not recommended as a component of other genetic investigations of this disorder.
