Mortality surveillance in the U.S. Army, 2005-2011.

PURPOSE: Mortality rates in the U.S. Army from 2005 to 2011 were examined over time and compared to the U.S. general population. METHOD: Cases were U.S. Army Soldiers (active duty or activated National Guard/Reserve) with dates of death between 2005 and 2011 and between 18 and 64 years of age in the Department of Defense Medical Mortality Registry. Age- and sex-adjusted annual mortality rates (AR) were calculated for each category of death and examined via linear regression. Proportions of underlying causes of death were also examined. RESULTS: The trend in AR in the U.S. Army significantly decreased for combat deaths, the average annual percent change (AAPC) = 15.2% decrease in the log of the rate (LAR); p = 0.04 and accident deaths, AAPC = 5.4% decrease in the LAR; p = 0.002 and significantly increased for suicides, AAPC = 10.6% increase in the LAR; p = 0.001. The trend in AR for suicides for the Army was significantly different compared to the U.S. general population, AAPC = 11.0% increase in the LAR; p < 0.001. CONCLUSIONS: Trends in rates of combat deaths and accident deaths declined although rates of suicides increased. The Army suicide rate increased in comparison to the United States. 70% of accident deaths were transportation related. Almost 70% of suicides and homicides were firearm related.

The effect of spirituality and religious attendance on the relationship between psychological distress and negative life events.

PURPOSE: The aim of this study was to assess the effect of religious attendance and spirituality on the relationship between negative life events and psychological distress. METHODS: This was a cross-sectional study of 1,071 community dwelling adults from East Baltimore, Maryland who participated in the fourth (2004-2005) wave of the Baltimore Epidemiologic Catchment Area study. The 20-item General Health Questionnaire (GHQ-20) was used to measure psychological distress. Multiple regression models were used to assess the association between negative life events and distress as well as to measure the effect of religious attendance and spirituality on the association between psychological distress and negative events while adjusting for demographic variables, past distress and social support from friends and relatives. RESULTS: In pooled analysis, negative events were significant predictors of distress, b = 1.00, ß = 0.072, p < 0.05. Religious attendance and spirituality did not affect or modify the association between negative events and distress. However, religious attendance was inversely associated with distress with higher frequency of attendance associated with lower distress after controlling for demographic and social support factors, b = -2.10, ß = -.110, p < 0.01 for attending 1-3 times a month; b = -2.39, ß = -0.156, p < 0.01 for attending weekly; and b = -3.13, ß = -0.160, p < 0.001 for attending more than once per week. In stratified analysis, negative events were associated with distress for those who were low on spirituality, b = 1.23, ß = 0.092, p < .05, but not for those who were high on spirituality; the association between religious attendance and decreased distress was true only for those scoring high in spirituality. Social support accounted for some of the inverse association between religious and distress. CONCLUSION: Religious attendance and spirituality may play a role in how people experience and deal with difficult life situations.

Alcohol use, alcohol problems, and problem behavior engagement among students at two schools in northern Mexico.

This study examined the association between alcohol-use problem severity, defined by number of DSM-IV alcohol Abuse and Dependence symptoms and frequency of alcohol use, and problem behavior engagement among Mexican students. A confidential survey was administered to 1229 students in grades 7-12 at two schools in a northern border city in Mexico. Youths were categorized into five groups based on their alcohol use frequency and symptoms of DSM-IV alcohol Abuse and Dependence, specifically: no lifetime alcohol use, lifetime alcohol use but none in the past year, past year alcohol use, one or two alcohol Abuse or Dependence symptoms, and three or more alcohol Abuse or Dependence symptoms. The association between five levels of alcohol-use problem severity and three problem behaviors, lifetime marijuana use, lifetime sexual intercourse, and past year arrest/law trouble, was examined using chi-square or Fisher's exact tests. Several alcohol-use problem severity categories were significantly different with respect to rates of lifetime marijuana use, lifetime sexual intercourse, and past year arrest/law trouble. Higher alcohol-use problem severity was associated with greater endorsement of problem behaviors. Knowing about variations in adolescent alcohol use and alcohol problems may be instrumental in determining if youths are also engaging in a range of other risk behaviors. Considering varying levels of alcohol use and alcohol problems is important for effective targeted prevention and treatment interventions.

A model of school problems, academic failure, alcohol initiation, and the relationship to adult heroin injection.

The current study uses structural equation modeling to investigate factors associated with alcohol initiation and injection heroin use. Baseline data from the NEURO-HIV Epidemiologic Study in Baltimore, Maryland, were used. Participants were 404 injection heroin users (M(age) = 32.72) with a history of regular injection in their lifetime. Latent variables were created for self-reported school problems and academic failure. The final model indicated that greater school problems were associated with earlier alcohol initiation (ß = -0.22, p < .001) and earlier alcohol initiation was associated with greater frequency of recent heroin use (ß = -0.12, p < .05). Academic failure was directly related to greater frequency of recent heroin injection (ß = 0.15, p < .01). The results expand research investigating the relationship between adolescent behavior and illicit drug use in adulthood.

Correlates of risky injection practices among past-year injection drug users among the US general population.

BACKGROUND: With an estimated 1 million active injection drug users (IDUs), injection drug use continues to be a public health concern in the United States. Risky injection practices have been associated with the transmission of HIV, Hepatitis B and C, as well as other skin and soft tissue infections. METHODS: We used data from 463 respondents, aged 18 and older, who were past-year IDUs in the 2005-2008 National Survey of Drug Use and Health (NSDUH). We investigated correlates of risky injection behavior among these recent IDUs. RESULTS: Older age (≥ 35 versus 18-25) was associated with reusing one's own needle at last injection (aOR=1.80 [1.02-3.17], as were past year heroin (aOR=2.59 [1.18-5.66]) and cocaine injection (aOR=2.17 [1.13-4.15]). Past year crack cocaine use was positively associated with not cleaning needles with bleach (aOR=2.18 [1.10-4.33]). Past year cocaine injection was associated with obtaining needles in a risky manner (aOR=2.29 [1.23-4.25]). Methamphetamine injection was associated with obtaining needles in less risky ways (aOR=0.41 [0.20-0.84]). CONCLUSION: Our findings indicate that some IDUs are continuing to engage in high risk injection behaviors. The identification of potential at-risk populations of IDUs may have implications for harm reduction interventions and HIV prevention programs.
