Assessing the Impact of Different Depression Treatment Success Metrics on Organizational Performance.

Objective: The Patient Health Questionnaire-9 (PHQ-9) is commonly used to assess depression symptoms, but its associated treatment success criteria (i.e., metrics) are inconsistently defined. The authors aimed to analyze the impact of metric choice on outcomes and discuss implications for clinical practice and research. Methods: Analyses included three overlapping and nonexclusive time cohorts of adult patients with depression treated in 33 organizations between 2008 and 2018. Average depression improvement rates were calculated according to eight metrics. Organization-level rank orders defined by these metrics were calculated and correlated. Results: The 12-month cohort had higher rates of metrics indicating treatment success than did the 3- and 6-month cohorts; the degree of improvement varied by metric, although all organization-level rank orders were highly correlated. Conclusions: Different PHQ-9 treatment metrics are associated with disparate improvement rates. Organization-level rankings defined by different metrics are highly correlated. Consistency of metric use may be more important than specific metric choice.

Demographic-Specific Rates for Life Events in the Cardiovascular Health Study and Comparisons With Other Studies.

PURPOSE OF THE STUDY: (1a) We use the Cardiovascular Health Study (CHS), a multi-site heterogeneous sample of Medicare enrollees (N = 5,849) to provide rates for specific life events experienced within 6 months; (1b) We present rates for 29 other studies of community-residing older adults (N = 41,308); (2) For the CHS, we provide demographic-specific rates and predicted probabilities for age [young-old (65-75) vs old-old (≥75)], gender, race, marital status, and education. DESIGN/METHODS: The CHS sample is 57.6% women, 84.2% white (15.8% black), and 66.3% married. Mean age is 72.8 years (standard deviation [SD] = 5.6, range = 65-100) and education is 13.7 years (SD = 4.8). Life events were interviewer-assessed. Regressions estimated associations of life event rates with demographic groups (e.g., age), controlling for other demographic variables (e.g., gender, etc.). RESULTS: (1a) CHS rates ranged from 44.7% (death of someone close) to 1.1% (retirement/work changes). (1b) Most life event studies used total scores and only 5 that met our inclusion criteria used time intervals <1 year; longer intervals were associated with higher rates. (2) In the CHS, the life event for illnesses was related to 5 demographic variables (net the other 4 demographic variables), difficulties caregiving to 4, and worse relationships to 3 demographic variables. Race was related to 8 life events, marital status to 7, education to 6, and age to 4 events. IMPLICATIONS: By identifying demographic groups at highest risk for life events, this research focuses on older adults at greatest risk for health problems. These data are necessary for translating research into interventions, practice, and policy.

Technology Use, Preferences, and Capacity in Injured Patients at Risk for Posttraumatic Stress Disorder.

OBJECTIVE: This investigation comprehensively assessed the technology use, preferences, and capacity of diverse injured trauma survivors with posttraumatic stress disorder (PTSD) symptoms. METHOD: A total of 121 patients participating in a randomized clinical trial (RCT) of stepped collaborative care targeting PTSD symptoms were administered baseline one-, three-, and six-month interviews that assessed technology use. Longitudinal data about the instability of patient cell phone ownership and phone numbers were collected from follow-up interviews. PTSD symptoms were also assessed over the course of the six months after injury. Regression analyses explored the associations between cell phone instability and PTSD symptoms. RESULTS: At baseline, 71.9% (n = 87) of patients reported current cell phone ownership, and over half (58.2%, n = 46) of these patients possessed basic cell phones. Only 19.0% (n = 23) of patients had no change in cell phone number or physical phone over the course of the six months postinjury. In regression models that adjusted for relevant clinical and demographic characteristics, cell phone instability was associated with higher six-month postinjury PTSD symptom levels (p < 0.001). CONCLUSIONS: Diverse injured patients at risk for the development of PTSD have unique technology use patterns, including high rates of cell phone instability. These observations should be strongly considered when developing technology-supported interventions for injured patients with PTSD.

Changes in Physical Activity Barriers among American Indian Elders: A Pilot Study​.

The objective of the present study was to assess whether selfreported physical activity barriers could be reduced among American Indian elders who participated in a 6-week randomized physical activity trial that compared the use of a pedometer only to that of pedometers with step-count goal setting. Elders (N = 32) were compared on the Barriers to Being Physically Active Quiz after participating in a pilot physical activity trial. Elders were classified into high- and low-barrier groups at baseline and compared on self-reported physical activity, health-related quality of life, pedometer step counts, and 6-minute walk performance. At the conclusion of the 6-week trial, only the lack of willpower subscale significantly decreased. The low-barrier group reported significantly higher physical activity engagement and improved mental health quality of life than the high-barrier group. The groups did not differ on daily step counts or 6-minute walk performance. Additional research is needed with a larger sample to understand relevant activity barriers in this population and assess whether they can be modified through participation in structured physical activity and exercise programs.

Barriers to Cancer Care among American Indians and Alaska Natives.

INTRODUCTION: Cancer is among the leading causes of death in American Indians and Alaska Natives (AI/ANs), with rates increasing over the last two decades. Barriers in accessing cancer screening and treatment likely contribute to this situation. METHODS: We administered structured clinical interviews and conducted descriptive and multiple linear regression analyses of demographic, health, spiritual, and treatment factors associated with self-reported barriers to cancer care among 143 adult AI/AN oncology patients. RESULTS: High levels of satisfaction with cancer care, older age, positive mental health quality of life, and positive physical health quality of life were all significantly associated with lower scores for cancer care barriers, explaining 27% of the total model variance. CONCLUSION: Addressing barriers to cancer care might help to reduce health disparities among AI/AN oncology patients. Future research should determine whether reducing barriers improves engagement with cancer treatment and overall health outcomes.

A Randomized Trial of Collaborative Care for Perinatal Depression in Socioeconomically Disadvantaged Women: The Impact of Comorbid Posttraumatic Stress Disorder.

OBJECTIVE: The comorbidity of posttraumatic stress disorder (PTSD) with antenatal depression poses increased risks for postpartum depression and may delay or diminish response to evidence-based depression care. In a secondary analysis of an 18-month study of collaborative care for perinatal depression, the authors hypothesized that pregnant, depressed, socioeconomically disadvantaged women with comorbid PTSD would show more improvement in the MOMCare intervention providing Brief Interpersonal Psychotherapy and/or antidepressants, compared to intensive public health Maternity Support Services (MSS-Plus). METHODS: A multisite randomized controlled trial with blinded outcome assessment was conducted in the Seattle-King County Public Health System, July 2009-January 2014. Pregnant women were recruited who met criteria for a probable diagnosis of major depressive disorder (MDD) on the Patient Health Questionnaire-9 and/or dysthymia on the MINI-International Neuropsychiatric Interview (5.0.0). The primary outcome was depression severity at 3-, 6-, 12-and 18-month follow-ups; secondary outcomes included functional improvement, PTSD severity, depression response and remission, and quality of depression care. RESULTS: Sixty-five percent of the sample of 164 met criteria for probable comorbid PTSD. The treatment effect was significantly associated with PTSD status in a group-by-PTSD severity interaction, controlling for baseline depression severity (Wald χ²1 = 4.52, P = .03). Over the 18-month follow-up, those with comorbid PTSD in MOMCare (n = 48), versus MSS-Plus (n = 58), showed greater improvement in depression severity (Wald χ²1 = 8.51, P < .004), PTSD severity (Wald χ²1 = 5.55, P < .02), and functioning (Wald χ²1 = 4.40, P < .04); higher rates of depression response (Wald χ²1 = 4.13, P < .04) and remission (Wald χ²1 = 5.17, P < .02); and increased use of mental health services (Wald χ²1 = 39.87, P < .0001) and antidepressant medication (Wald χ²1 = 8.07, P < .005). Participants without comorbid PTSD in MOMCare (n = 33) and MSS-Plus (n = 25) showed equivalent improvement on these outcomes. CONCLUSIONS: Collaborative depression care had a greater impact on perinatal depressive outcomes for socioeconomically disadvantaged women with comorbid PTSD than for those without PTSD. Findings suggest that a stepped care treatment model for high-risk pregnant women with both MDD and PTSD could be integrated into public health systems in the United States. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT01045655.

COLLABORATIVE CARE FOR PERINATAL DEPRESSION IN SOCIOECONOMICALLY DISADVANTAGED WOMEN: A RANDOMIZED TRIAL.

BACKGROUND: Both antenatal and postpartum depression have adverse, lasting effects on maternal and child well-being. Socioeconomically disadvantaged women are at increased risk for perinatal depression and have experienced difficulty accessing evidence-based depression care. The authors evaluated whether "MOMCare,"a culturally relevant, collaborative care intervention, providing a choice of brief interpersonal psychotherapy and/or antidepressants, is associated with improved quality of care and depressive outcomes compared to intensive public health Maternity Support Services (MSS-Plus). METHODS: A randomized multisite controlled trial with blinded outcome assessment was conducted in the Seattle-King County Public Health System. From January 2010 to July 2012, pregnant women were recruited who met criteria for probable major depression and/or dysthymia, English-speaking, had telephone access, and ≥18 years old. The primary outcome was depression severity at 3-, 6-, 12-, 18-month postbaseline assessments; secondary outcomes included functional improvement, PTSD severity, depression response and remission, and quality of depression care. RESULTS: All participants were on Medicaid and 27 years old on average; 58% were non-White; 71% were unmarried; and 65% had probable PTSD. From before birth to 18 months postbaseline, MOMCare (n = 83) compared to MSS-Plus participants (n = 85) attained significantly lower levels of depression severity (Wald's χ(2) = 6.09, df = 1, P = .01) and PTSD severity (Wald's χ(2) = 4.61, df = 1, P = .04), higher rates of depression remission (Wald's χ(2) = 3.67, df = 1, P = .05), and had a greater likelihood of receiving ≥4 mental health visits (Wald's χ(2) = 58.23, df = 1, P < .0001) and of adhering to antidepressants in the prior month (Wald's χ(2) = 10.00, df = 1, P < .01). CONCLUSION: Compared to MSS-Plus, MOMCare showed significant improvement in quality of care, depression severity, and remission rates from before birth to 18 months postbaseline for socioeconomically disadvantaged women. Findings suggest that evidence-based perinatal depression care can be integrated into the services of a county public health system in the United States.

Caregiving among American Indians and Alaska Natives with cancer.

PURPOSE: Caregivers are an important source of support for oncology patients during cancer diagnosis and treatment, often helping patients manage barriers to care. Our study had three goals: to describe the characteristics of caregivers for American Indian and Alaska Native (AI/AN) oncology patients, to assess the similarities and differences between the perceptions of caregivers and patients regarding barriers to cancer care, and to compare AI/AN caregivers to non-AI/AN caregivers on perceived barriers to cancer care. METHODS: We conducted a structured interview that assessed perceived barriers to cancer care with a paired sample of 98 adult caregivers and 98 AI/AN oncology patients and to assess the degree of agreement between these two groups. We also investigated whether AI/AN and non-AI/AN caregivers had differing perceptions of barriers to cancer care. RESULTS: Caregivers reported that their role was very meaningful and not highly stressful. Caregivers and patients agreed 70 % of the time on specific barriers to cancer care. Both groups overwhelmingly reported financial and family or work issues as major barriers to care, whereas trust in providers was the least frequently endorsed barrier. A comparison of AI/AN and non-AI/AN caregivers revealed that AI/AN caregivers identified confidentiality among clinical staff as a significant barrier, whereas non-AI/AN caregivers perceived financial barriers as more significant. CONCLUSIONS: Finances, family, and work are perceived as the largest barriers to the receipt of cancer care for AI/AN oncology patients. Both patients and caregivers trusted health-care providers. Assessing barriers to care early in the assessment process may result in better engagement with cancer treatment by patients and their caregivers.

Genetic polymorphisms affecting susceptibility to mercury neurotoxicity in children: summary findings from the Casa Pia Children's Amalgam clinical trial.

Mercury (Hg) is neurotoxic, and children may be particularly susceptible to this effect. A current major challenge is identification of children who may be uniquely susceptible to Hg toxicity because of genetic predisposition. We examined the possibility that common genetic variants that are known to affect neurologic functions or Hg handling in adults would modify the adverse neurobehavioral effects of Hg exposure in children. Three hundred thirty subjects who participated as children in the recently completed Casa Pia Clinical Trial of Dental Amalgams in Children were genotyped for 27 variants of 13 genes that are reported to affect neurologic functions and/or Hg disposition in adults. Urinary Hg concentrations, reflecting Hg exposure from any source, served as the Hg exposure index. Regression modeling strategies were employed to evaluate potential associations between allelic status for individual genes or combinations of genes, Hg exposure, and neurobehavioral test outcomes assessed at baseline and for 7 subsequent years during the clinical trial. Among boys, significant modification of Hg effects on neurobehavioral outcomes over a broad range of neurologic domains was observed with variant genotypes for 4 of 13 genes evaluated. Modification of Hg effects on a more limited number of neurobehavioral outcomes was also observed for variants of another 8 genes. Cluster analyses suggested some genes interacting in common processes to affect Hg neurotoxicity. In contrast, significant modification of Hg effects on neurobehavioral functions among girls with the same genotypes was substantially more limited. These observations suggest increased susceptibility to the adverse neurobehavioral effects of Hg among children, particularly boys, with genetic variants that are relatively common to the general human population. These findings advance public health goals to identify factors underlying susceptibility to Hg toxicity and may contribute to strategies for preventing adverse health risks associated with Hg exposure.

Culturally relevant treatment services for perinatal depression in socio-economically disadvantaged women: the design of the MOMCare study.

BACKGROUND: Depression during pregnancy has been demonstrated to be predictive of low birthweight, prematurity, and postpartum depression. These adverse outcomes potentially have lasting effects on maternal and child well-being. Socio-economically disadvantaged women are twice as likely as middle-class women to meet diagnostic criteria for antenatal major depression (MDD), but have proven difficult to engage and retain in treatment. Collaborative care treatment models for depression have not been evaluated for racially/ethnically diverse, pregnant women on Medicaid receiving care in a public health system. This paper describes the design, methodology, culturally relevant enhancements, and implementation of a randomized controlled trial of depression care management compared to public health Maternity Support Services (MSS). METHODS: Pregnant, public health patients, >18 years with a likely diagnosis of MDD or dysthymia, measured respectively by the Patient Health Questionnaire-9 (PHQ-9) or the Mini-International Neuropsychiatric Interview (MINI), were randomized to the intervention or to public health MSS. The primary outcome was reduction in depression severity from baseline during pregnancy to 18-months post-baseline (one-year postpartum). BASELINE RESULTS: 168 women with likely MDD (96.4%) and/or dysthymia (24.4%) were randomized. Average age was 27.6 years and gestational age was 22.4 weeks; 58.3% racial/ethnic minority; 71.4% unmarried; 22% no high school degree/GED; 65.3% unemployed; 42.1% making <$10,000 annually; 80.4% having recurrent depression; 64.6% PTSD, and 72% unplanned pregnancy. CONCLUSIONS: A collaborative care team, including a psychiatrist, psychologist, project manager, and 3 social workers, met weekly, collaborated with the patients' obstetrics providers, and monitored depression severity using an electronic tracking system. Potential sustainability of the intervention within a public health system requires further study.

Genetic polymorphisms of catechol-O-methyltransferase modify the neurobehavioral effects of mercury in children.

Mercury (Hg) is neurotoxic and children may be particularly susceptible to this effect. A current major challenge is identification of children who may be uniquely susceptible to Hg toxicity because of genetic disposition. This study examined the hypothesis that genetic variants of catechol-O-methyltransferase (COMT) that are reported to alter neurobehavioral functions that are also affected by Hg in adults might modify the adverse neurobehavioral effects of Hg exposure in children. Five hundred and seven children, 8-12 yr of age at baseline, participated in a clinical trial to evaluate the neurobehavioral effects of Hg from dental amalgam tooth fillings. Subjects were evaluated at baseline and at seven subsequent annual intervals for neurobehavioral performance and urinary Hg levels. Following the clinical trial, genotyping assays were performed for single-nucleotide polymorphisms (SNPs) of COMT rs4680, rs4633, rs4818, and rs6269 on biological samples provided by 330 of the trial participants. Regression-modeling strategies were employed to evaluate associations between allelic status, Hg exposure, and neurobehavioral test outcomes. Similar analysis was performed using haplotypes of COMT SNPs. Among girls, few interactions for Hg exposure and COMT variants were found. In contrast, among boys, numerous gene-Hg interactions were observed between individual COMT SNPs, as well as with a common COMT haplotype affecting multiple domains of neurobehavioral function. These findings suggest increased susceptibility to the adverse neurobehavioral effects of Hg among children with common genetic variants of COMT, and may have important implications for strategies aimed at protecting children from the potential health risks associated with Hg exposure.

The role of opioid prescription in incident opioid abuse and dependence among individuals with chronic noncancer pain: the role of opioid prescription.

OBJECTIVE: Increasing rates of opioid use disorders (OUDs) (abuse and dependence) among patients prescribed opioids are a significant public health concern. We investigated the association between exposure to prescription opioids and incident OUDs among individuals with a new episode of a chronic noncancer pain (CNCP) condition. METHODS: We utilized claims data from the HealthCore Database for 2000 to 2005. The dataset included all individuals aged 18 and over with a new CNCP episode (no diagnosis in the prior 6 mo), and no opioid use or OUD in the prior 6 months (n=568,640). We constructed a single multinomial variable describing prescription on opioid days supply (none, acute, and chronic) and average daily dose (none, low dose, medium dose, and high dose), and examined the association between this variable and an incident OUD diagnosis. RESULTS: Patients with CNCP prescribed opioids had significantly higher rates of OUDs compared with those not prescribed opioids. Effects varied by average daily dose and days supply: low dose, acute (odds ratio [OR]=3.03; 95% confidence interval [CI], 2.32, 3.95); low dose, chronic (OR=14.92; 95% CI, 10.38, 21.46); medium dose, acute (OR=2.80; 95% CI, 2.12, 3.71); medium dose, chronic (OR=28.69; 95% CI, 20.02, 41.13); high dose, acute (OR=3.10; 95% CI, 1.67, 5.77); and high dose, chronic (OR=122.45; 95% CI, 72.79, 205.99). CONCLUSIONS: Among individuals with a new CNCP episode, prescription opioid exposure was a strong risk factor for incident OUDs; magnitudes of effects were large. Duration of opioid therapy was more important than daily dose in determining OUD risk.

Improving depression treatment for women: integrating a collaborative care depression intervention into OB-GYN care.

BACKGROUND: Women have higher rates of depression and often experience depression symptoms during critical reproductive periods, including adolescence, pregnancy, postpartum, and menopause. Collaborative care intervention models for mood disorders in patients receiving care in an OB-GYN clinic setting have not been evaluated. Study design and methodology for a randomized controlled trial of collaborative care depression management versus usual care in OB-GYN clinics and the details of the adapted collaborative care intervention and model implementation are described in this paper. METHODS: Women over age 18 years with clinically significant symptoms of depression, as measured by a Patient Health Questionnaire-9 (PHQ-9) score ≥10 and a clinical diagnosis of major depression or dysthymia, were randomized to the study intervention or to usual care and were followed for 18 months. The primary outcome assessed was change over time in the SCL-20 depression scale between baseline and 12 months. BASELINE RESULTS: Two hundred five women were randomized: 57% white, 20% African American, 9% Asian or Pacific Islander, 7% Hispanic, and 6% Native American. Mean age was 39 years. 4.6% were pregnant and 7.5% were within 12 months postpartum. The majority were single (52%), and 95% had at least the equivalent of a high school diploma. Almost all patients met DSM IV criteria for major depression (99%) and approximately 33% met criteria for dysthymia. CONCLUSIONS: An OB-GYN collaborative care team, including a social worker, a psychiatrist, and an OB-GYN physician, who met weekly and used an electronic tracking system for patients was the essential element of the proposed depression care treatment model described here. Further study of models that improve quality of depression care that are adapted to the unique OB-GYN setting is needed.

Modification of neurobehavioral effects of mercury by genetic polymorphisms of metallothionein in children.

Mercury (Hg) is neurotoxic, and children may be particularly susceptible to this effect. A current major challenge is the identification of children who may be uniquely susceptible to Hg toxicity because of genetic disposition. We examined the hypothesis that genetic variants of metallothionein (MT) that are reported to affect Hg toxicokinetics in adults would modify the neurotoxic effects of Hg in children. Five hundred seven children, 8-12 years of age at baseline, participated in a clinical trial to evaluate the neurobehavioral effects of Hg from dental amalgam tooth fillings. Subjects were evaluated at baseline and at 7 subsequent annual intervals for neurobehavioral performance and urinary Hg levels. Following the completion of the clinical trial, we performed genotyping assays for variants of MT isoforms MT1M (rs2270837) and MT2A (rs10636) on biological samples provided by 330 of the trial participants. Regression modeling strategies were employed to evaluate associations between allelic status, Hg exposure, and neurobehavioral test outcomes. Among girls, few significant interactions or independent main effects for Hg exposure and either of the MT gene variants were observed. In contrast, among boys, numerous significant interaction effects between variants of MT1M and MT2A, alone and combined, with Hg exposure were observed spanning multiple domains of neurobehavioral function. All dose-response associations between Hg exposure and test performance were restricted to boys and were in the direction of impaired performance. These findings suggest increased susceptibility to the adverse neurobehavioral effects of Hg among children with relatively common genetic variants of MT, and may have important public health implications for future strategies aimed at protecting children and adolescents from the potential health risks associated with Hg exposure. We note that because urinary Hg reflects a composite exposure index that cannot be attributed to a specific source, these findings do not support an association between Hg in dental amalgams specifically and the adverse neurobehavioral outcomes observed.

Modification of neurobehavioral effects of mercury by a genetic polymorphism of coproporphyrinogen oxidase in children.

Mercury (Hg) is neurotoxic, and children may be particularly susceptible to this effect. A current major challenge is the identification of children who may be uniquely susceptible to Hg toxicity because of genetic disposition. We examined the hypothesis that CPOX4, a genetic variant of the heme pathway enzyme coproporphyrinogen oxidase (CPOX) that affects susceptibility to mercury toxicity in adults, also modifies the neurotoxic effects of Hg in children. Five hundred seven children, 8-12 years of age at baseline, participated in a clinical trial to evaluate the neurobehavioral effects of Hg from dental amalgam tooth fillings in children. Subjects were evaluated at baseline and at 7 subsequent annual intervals for neurobehavioral performance and urinary mercury levels. Following the completion of the clinical trial, genotyping assays for CPOX4 allelic status were performed on biological samples provided by 330 of the trial participants. Regression modeling strategies were employed to evaluate associations between CPOX4 status, Hg exposure, and neurobehavioral test outcomes. Among girls, few significant CPOX4-Hg interactions or independent main effects for Hg or CPOX4 were observed. In contrast, among boys, numerous significant interaction effects between CPOX4 and Hg were observed spanning all 5 domains of neurobehavioral performance. All underlying dose-response associations between Hg exposure and test performance were restricted to boys with the CPOX4 variant, and all of these associations were in the expected direction where increased exposure to Hg decreased performance. These findings are the first to demonstrate genetic susceptibility to the adverse neurobehavioral effects of Hg exposure in children. The paucity of responses among same-age girls with comparable Hg exposure provides evidence of sexual dimorphism in genetic susceptibility to the adverse neurobehavioral effects of Hg in children and adolescents.

Mental health disorders and long-term opioid use among adolescents and young adults with chronic pain.

PURPOSE: The purpose of this study was to examine the association between mental health disorders and subsequent risk for long-term opioid use among adolescents and young adults presenting with common chronic pain complaints (back pain, neck pain, headache, and arthritis/joint pain). METHODS: Using claims data from January 1, 2001 to June 30, 2008, we conducted a longitudinal analysis of opioid use patterns among 13-24-year-old subjects presenting with a new episode of chronic pain. Long-term opioid use was defined as receiving >90 days of opioids within a 6-month period with no gap of >30 days in use of opioids in the 18 months after the first qualifying pain diagnosis. Mental health disorders were identified from claims in the 6 months before the first qualifying pain diagnosis. RESULTS: Fifty-nine thousand seventy-seven youth met criteria for a new episode of chronic pain. Among these youth, 321 (.5%) met criteria for long-term opioid use, and 16,172 (27.4%) had some opioid use. After controlling for demographic and clinical factors, youth with preexisting mental health diagnoses had a 2.4-fold increased risk of subsequently receiving long-term opioids versus no opioids (odds ratio = 2.36, 95% confidence interval = 1.73-3.23) and a 1.8-fold increased likelihood of receiving long-term opioids versus some opioids (odds ratio = 1.83, 95% confidence interval = 1.34-2.50). CONCLUSIONS: Mental health disorders are associated with increased risk for long-term opioid use among adolescents and emerging young adults. Further study is warranted to examine risks and benefits of long-term opioid use in this population.

Influence of framing and graphic format on comprehension of risk information among American Indian tribal college students.

We evaluated methods for presenting risk information by administering six versions of an anonymous survey to 489 American Indian tribal college students. All surveys presented identical numeric information, but framing varied. Half expressed prevention benefits as relative risk reduction, half as absolute risk reduction. One third of surveys used text to describe prevention benefits; one third used text plus bar graph; one third used text plus modified bar graph incorporating a culturally tailored image. The odds ratio (OR) for correct risk interpretation for absolute risk framing vs. relative risk framing was 1.40 (95 % CI = 1.01, 1.93). The OR for correct interpretation of text plus bar graph vs. text only was 2.16 (95 % CI = 1.46, 3.19); OR for text plus culturally tailored bar graph vs. text only was 1.72 (95 % CI = 1.14, 2.60). Risk information including a bar graph was better understood than text-only information; a culturally tailored graph was no more effective than a standard graph.

Depression in pregnancy is associated with preexisting but not pregnancy-induced hypertension.

BACKGROUND: The aim was to examine whether depression is associated with preexisting hypertension or pregnancy-induced hypertension in a large sample of women attending a university-based obstetrics clinic. METHODS: In this prospective study, participants were 2398 women receiving ongoing prenatal care at a university-based obstetrics clinic from January 2004 through January 2009. Prevalence of depression was measured using the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria based on the Patient Health Questionnaire-9 as well as the self-reported use of antidepressant medication. Evidence of preexisting hypertension, pregnancy-induced hypertension and preeclampsia/eclampsia was determined by obstetrician International Classification of Diseases, Ninth Revision codes. Logistic regression was used to quantify the association between hypertension in pregnancy and antenatal depression. RESULTS: After adjusting for sociodemographic variables, chronic medical conditions, smoking and prior pregnancy complications, women with preexisting hypertension had an increased risk of any depression (minor, major, use of antidepressants) [odds ratio (OR)=1.55, 95% confidence interval (CI) 1.08-2.23) and major depression and/or use of antidepressants (OR=1.65, 95% CI 1.10-2.48) compared to women without hypertension. No differences were seen in risk of depression in women with pregnancy-induced hypertension or preeclampsia/eclampsia compared to those without hypertension. CONCLUSION: Women with preexisting hypertension, but not pregnancy-induced hypertension, are more likely to meet criteria for an antenatal depressive disorder and/or to be treated with antidepressants and could be targeted by obstetricians for screening for depression and enhanced treatment.

The association between intensive care unit admission and subsequent depression in patients with diabetes.

OBJECTIVE: To examine whether intensive care unit (ICU) admission is independently associated with increased risk of major depression in patients with diabetes. METHODS: This prospective cohort study included 3596 patients with diabetes enrolled in the Pathways Epidemiologic Follow-Up Study, of whom 193 had at least one ICU admission over a 3-year period. We controlled for baseline depressive symptoms, demographics, and clinical characteristics. We examined associations between ICU admission and subsequent major depression using logistic regression. RESULTS: There were 2624 eligible patients who survived to complete follow-up; 98 had at least one ICU admission. Follow-up assessments occurred at a mean of 16.4 months post-ICU for those who had an ICU admission. At baseline, patients who had an ICU admission tended to be depressed, older, had greater medical comorbidity, and had more diabetic complications. At follow-up, the point prevalence of probable major depression among patients who had an ICU admission was 14% versus 6% among patients without an ICU admission. After multivariate adjustment, ICU admission was independently associated with subsequent probable major depression (Odds Ratio 2.07, 95% confidence interval (1.06-4.06)). Additionally, baseline probable major depression was significantly associated with post-ICU probable major depression. CONCLUSIONS: ICU admission in patients with diabetes is independently associated with subsequent probable major depression. Additional research is needed to identify at-risk patients and potentially modifiable ICU exposures in order to inform future interventional studies with the goal of decreasing the burden of comorbid depression in older patients with diabetes who survive critical illnesses.

Does pedometer goal setting improve physical activity among Native elders? Results from a randomized pilot study.

We examined if step-count goal setting resulted in increases in physical activity and walking compared to only monitoring step counts with pedometers among American Indian/Alaska Native elders. Outcomes included step counts, self-reported physical activity and well-being, and performance on the 6-minute walk test. Although no significant between-group differences were found, within-group analyses indicated that elders significantly improved on the majority of step count, physical activity, health-related quality of life, and 6-minute walk outcomes.
