Objective To describe new onset and persistence of self reported post-traumatic stress disorder symptoms in a large population based military cohort, many of whom were deployed in support of the wars in Iraq and Afghanistan. Design Prospective cohort analysis. Setting and participants Survey enrolment data from the millennium cohort (July 2001 to June 2003) obtained before the wars in Iraq and Afghanistan. Follow-up (June 2004 to February 2006) data on health outcomes collected from 50 184 participants. Main outcome measures Self reported post-traumatic stress disorder as measured by the posttraumatic stress disorder checklist—civilian version using Diagnostic and Statistical Manual of Mental Disorders, fourth edition criteria. Results More than 40% of the cohort were deployed between 2001 and 2006; between baseline and follow-up, 24% deployed for the first time in support of the wars in Iraq and Afghanistan. New incidence rates of 10-13 cases of post-traumatic stress disorder per 1000 person years occurred in the millennium cohort. New onset self reported post-traumatic stress disorder symptoms or diagnosis were identified in 7.6-8.7% of deployers who reported combat exposures, 1.4-2.1% of deployers who did not report combat exposures, and 2.3-3.0% of non-deployers. Among those with self reported symptoms of post-traumatic stress disorder at baseline, deployment did not affect persistence of symptoms. Conclusions After adjustment for baseline characteristics, these prospective data indicate a threefold increase in new onset self reported post-traumatic stress disorder symptoms or diagnosis among deployed military personnel who reported combat exposures. The findings define the importance of post-traumatic stress disorder in this population and emphasise that specific combat exposures, rather than deployment itself, significantly affect the onset of symptoms of post-traumatic stress disorder after deployment.

There is growing interest in the relation of built environments to physical activity, obesity, and other health outcomes. The purpose of the present study was to test associations of neighborhood built environment and median income to multiple health outcomes and examine whether associations are similar for low- and high-income groups. This was a cross-sectional study of 32 neighborhoods in Seattle, WA and Baltimore, MD regions, stratified by income and walkability, and conducted between 2001 and 2005. Participants were adults aged 20-65years (n=2199; 26% ethnic minority). The main outcomes were daily minutes of moderate-to-vigorous physical activity (MVPA) from accelerometer monitoring, body mass index (BMI) based on self-report, and mental and physical quality of life (QoL) assessed with the SF-12. We found that MVPA was higher in high- vs. low-walkability neighborhoods but did not differ by neighborhood income. Overweight/obesity (BMI > or = 25) was lower in high-walkability neighborhoods. Physical QoL was higher in high-income neighborhoods but unrelated to walkability. Adjustment for neighborhood self-selection produced minor changes. We concluded that living in walkable neighborhoods was associated with more physical activity and lower overweight/obesity but not with other benefits. Lower- and higher-income groups benefited similarly from living in high-walkability neighborhoods. Adults in higher-income neighborhoods had lower BMI and higher physical QoL.

OBJECTIVE To determine factors influencing outpatient mental health service use by children in foster care. METHOD Detailed survey and administrative data were collected on 480 children who entered long-term foster care in San Diego County from May 1990 through October 1991. These data were linked with claims data from Medicaid and San Diego County Mental Health Services information systems. A Poisson regression model was used to determine whether the following factors influenced outpatient mental health service use: age, race/ethnicity, gender, maltreatment history, placement pattern, and behavioral problems as measured by the Achenbach Child Behavior Checklist (CBCL). RESULTS Except for maltreatment history, all independent variables included in the multivariate regression model were statistically significant. The total number of outpatient mental health visits increased with age, male gender, and non-relative foster placements. Relative to Caucasians, visits were lower for Latinos, and Asian/Others, but comparable for African-Americans. Concerning maltreatment history, differences were only found in one category; children experiencing caretaker absence received fewer visits compared to children who did not experience caretaker absence. Children with CBCL Total Problem Scale T-scores of 60 or greater had significantly more visits than those with a score less than 60. CONCLUSIONS Both clinical and non-clinical factors influence outpatient mental health service use by foster children. Limitations imposed by gender, race/ethnicity, and placement setting need to be addressed by child welfare policies. These finding suggest that guidelines are needed to systematically link children in foster care with behavioral problems to appropriate services.

Retinol is involved in bone remodeling, and excessive intake has been linked to bone demineralization, yet its role in osteoporosis has received little evaluation. We studied the associations of retinol intake with bone mineral density (BMD) and bone maintenance in an ambulatory community‐dwelling cohort of 570 women and 388 men, aged 55–92 years at baseline. Regression analyses, adjusted for standard osteoporosis covariates, showed an inverse U‐shaped association of retinol, assessed by food‐frequency questionnaires in 1988–1992, with baseline BMD, BMD measured 4 years later, and BMD change. Supplemental retinol use, reported by 50% of women and 39% of men, was an effect modifier in women; the associations of log retinol with BMD and BMD change were negative for supplement users and positive for nonusers at the hip, femoral neck, and spine. At the femoral neck, for every unit increase in log retinol intake, supplement users had 0.02 g/cm2 (p = 0.02) lower BMD and 0.23% (p = 0.05) greater annual bone loss, and nonusers had 0.02 g/cm2 (p = 0.04) greater BMD and 0.22% (p = 0.19) greater bone retention. However, among supplement users, retinol from dietary and supplement sources had similar associations with BMD, suggesting total intake is more important than source. In both sexes, increasing retinol became negatively associated with skeletal health at intakes not far beyond the recommended daily allowance (RDA), intakes reached predominately by supplement users. This study suggests there is a delicate balance between ensuring that the elderly consume sufficient vitamin A and simultaneously cautioning against excessive retinol supplementation.

Participants (N=357) were randomly assigned to 1 of 3 conditions: lay health advisor (promotora) plus tailored print materials, tailored print materials only (tailored), or off-the-shelf print materials (control). The primary outcomes were calories from fat and daily grams of fiber. Secondary outcomes included total energy intake, total and saturated fat intake, and total carbohydrates. Adjusted for baseline values, calories from fat were 29%, 30%, and 30% for the promotora, tailored, and control conditions, respectively, and grams of fiber consumed were 16 g, 17 g, and 16 g. Significant Condition X Time interactions were not observed between baseline and 12-weeks postintervention. The LHA condition achieved significantly lower levels of energy intake, total fat and saturated fat, and total carbohydrates. The relative superiority of the promotora condition may derive from the personal touch achieved in the face-to-face interactions or from the womens use of print materials under the promotoras guidance.

BACKGROUND The stress of military deployment may compound occupational stress experienced in the military and manifest in maladaptive coping behaviors such as cigarette smoking. The current study describes new smoking among never-smokers, smoking recidivism among past smokers, and change in daily smoking among smokers in relation to military deployment. METHODS The Millennium Cohort is a 21-year longitudinal study. The current analysis utilized participants (N=48,304) who submitted baseline data (July 2001-June 2003) before the current conflicts in Iraq and Afghanistan and follow-up data (June 2004-January 2006) on health measures. New smoking was identified among baseline never-smokers, smoking recidivism among baseline past smokers, and increased or decreased daily smoking among baseline smokers. Analyses were conducted March 2007-April 2007. RESULTS Among never-smokers, smoking initiation was identified in 1.3% of nondeployers and 2.3% of deployers. Among past smokers, smoking resumption occurred in 28.7% of nondeployers and 39.4% of those who deployed. Smoking increased 44% among nondeployers and 57% among deployers. Those who deployed and reported combat exposures were at 1.6 times greater odds of initiating smoking among baseline never-smokers (95% CI=1.2, 2.3) and at 1.3 times greater odds of resuming smoking among baseline past smokers when compared to those who did not report combat exposures. Other deployment factors independently associated with postdeployment smoking recidivism included deploying for >9 months and deploying multiple times. Among those who smoked at baseline, deployment was not associated with changes in daily amount smoked. CONCLUSIONS Military deployment is associated with smoking initiation and, more strongly, with smoking recidivism, particularly among those with prolonged deployments, multiple deployments, or combat exposures. Prevention programs should focus on the prevention of smoking relapse during or after deployment.

The present study explored whether perceived neighborhood environmental attributes associated with physical activity differ by neighborhood income. Adults aged 20-65 years (n=2199; 48% female; mean age=45 years; 26% ethnic minority) were recruited from 32 neighborhoods from the Seattle, WA and Baltimore, MD regions that varied in objectively measured walkability and neighborhood income. Perceived built and social environment variables were assessed with the Neighborhood Environment Walkability Scale. There were neighborhood income disparities on 10 of 15 variables. Residents from high-income neighborhoods reported more favorable esthetics, pedestrian/biking facilities, safety from traffic, safety from crime, and access to recreation facilities than residents of low-income areas (all ps <0.001). Low-income neighborhoods may lack amenities and safety attributes that can facilitate high levels of physical activity for both transportation and recreation purposes.

Predictors of Outpatient Mental Health Service Use—The Role of Foster Care Placement Change

Sigrid James; John Landsverk; Donald J. Slymen; Laurel K. Leslie

This study examined the relationship between placement change and outpatient mental health service use. It is based on (1) conceptual propositions about the impact of the foster care living context on mental health service use, and (2) empirical knowledge about the adverse consequences of placement change. Results of the study, which were based on a cohort of 570 children in foster care in San Diego County, suggest an association between placement changes in child welfare and use of outpatient mental health services. Specifically, an increase in the number of placement changes predicted a greater rate of outpatient mental health visits. The study further found that children who experienced behavior-related placement changes received more outpatient mental health visits than children who experienced placement changes for other reasons. Follow-up analyses of the 144 children who experienced any behavior-related placement changes further indicated that the rate of outpatient mental health service use almost doubled in the 90 days following the first behavior-related placement change. Findings from this study have implications for the practice, policy and research fields in child welfare as well as mental health.

Secondary depression in anxiety neurosis.

John Clancy; Russell Noyes; Paul R. Hoenk; Donald J. Slymen

Forty-four per cent of 112 patients with anxiety neurosis reported episodes of depression during the course of their illness compared with only 7 per cent of surgical controls. Although the majority developed in response to environmental circumstances and were of brief duration, they commonly led to psychiatric treatment or hospitalization in this group of patients. Patients who developed this complication were shown to have a more chronic and severe underlying illness.

Using longitudinal data from the National Survey on Child and Adolescent Well-Being (NSCAW), this study investigates entry into intensive or restrictive settings during a 36-month study period. Specifically, this analysis examines entry into treatment foster care, group homes, residential treatment, and inpatient psychiatric care for youth placed into out-of-home care (n = 981). It aims to determine at what point in their first out-of-home episodes and for what reasons youth entered such settings. As NSCAW used a national probability sampling design,this analysis provides national estimates about entry into intensive or restrictive settings for youth in out-of-home care. Twenty-five percent of youth (n = 280) experienced an intensive or restrictive setting during their first out-of-home care episode; 70% were in either group homes (33.2%) or residential treatment settings (37.0%).About half of the youth with such placements (48.9%) were placed into intensive or restrictive settings as a first placement during their first out-of-home episode.
