Suicidal ideation among college students in the United States.

This study analyzed data from the 1995 National College Health Risk Behavior Survey (NCHRBS) to assess the prevalence of suicidal ideation among college students in the United States and to examine the association between suicidal ideation and substance use in this population. The NCHRBS used a mail questionnaire to assess health-risk behaviors in a nationally representative sample of undergraduate students. During the 12 months preceding the survey, 10% of the students had seriously considered attempting suicide. When controlling for demographic characteristics, the analysis showed that students who had considered suicide were at increased odds of using tobacco, alcohol, and illegal drugs. These results suggest that colleges and universities should establish suicide prevention programs that also address the related problem of substance use.

Depression among Latinos in the United States: A meta-analytic review.

The authors conducted a meta-analytic review to assess the prevalence of major depressive disorder and depressive symptoms among Latinos compared with non-Latino Whites in the United States using community-based data. Random-effects estimates were calculated for 8 studies meeting inclusion criteria that reported lifetime prevalence of major depressive disorder (combined N = 76,270) and for 23 studies meeting inclusion criteria that reported current prevalence of depressive symptoms (combined N = 38,997). Findings did not indicate a group difference in lifetime prevalence of major depressive disorder (odds ratio = 0.89, 95% confidence interval = 0.72, 1.10). Latinos reported more depressive symptoms than non-Latino Whites (standardized mean difference = 0.19, 95% confidence interval = 0.12, 0.25); however, this effect was small and does not appear to suggest a clinically meaningful preponderance of depressive symptoms among Latinos. Findings are examined in the context of theories on vulnerability and resilience, and recommendations for future research are discussed.

Reasons for conversion to Islam among women in the United States.

Nine reported reasons for converting to Islam were quantitatively assessed regarding prevalence and importance among 304 women in the United States. The appeal of Muslim moral values and dissatisfaction with one’s former faith were primary reasons, followed closely by enhanced sense of identity and alignment with cultural views (regarding ethnic diversity and gender roles). Active (theological and personal) reasons for conversion were more important and prevalent than passive (social) reasons. Qualitative analyses of additional write-in responses suggested four other reasons for conversion, including the appeal of Muslim tenets and an increased sense of significance/meaning. Findings are discussed in terms of implications for future research. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Predictors of parenting stress among gay adoptive fathers in the United States.

The authors examined correlates of parenting stress among 230 gay adoptive fathers across the United States through an Internet survey. As with previous research on adoptive parents, results showed that fathers with less social support, older children, and children who were adopted at older ages reported more parenting stress. Moreover, gay fathers who had a less positive gay identity also reported more parenting stress. These 4 variables accounted for 33% of the variance in parenting stress; effect sizes were medium to large. Our results suggest the importance of social support and a positive gay identity in facilitating successful parenting outcomes among gay adoptive fathers.

Excess mortality among blacks and whites in the United States

BACKGROUND: Although the general relations between race, socioeconomic status, and mortality in the United States are well known, specific patterns of excess mortality are not well understood. METHODS: Using standard demographic techniques, we analyzed death certificates and census data and made sex-specific population-level estimates of the 1990 death rates for people 15 to 64 years of age. We studied mortality among blacks in selected areas of New York City, Detroit, Los Angeles, and Alabama (in one area of persistent poverty and one higher-income area each) and among whites in areas of New York City, metropolitan Detroit, Kentucky, and Alabama (one area of poverty and one higher-income area each). Sixteen areas were studied in all. RESULTS: When they were compared with the nationwide age-standardized annual death rate for whites, the death rates for both sexes in each of the poverty areas were excessive, especially among blacks (standardized mortality ratios for men and women in Harlem, 4.11 and 3.38; in Watts, 2.92 and 2.60; in central Detroit, 2.79 and 2.58; and in the Black Belt area of Alabama, 1.81 and 1.89). Boys in Harlem who reached the age of 15 had a 37 percent chance of surviving to the age of 65; for girls, the likelihood was 65 percent. Of the higher-income black areas studied, Queens--Bronx had the income level most similar to that of whites and the lowest standardized mortality ratio (men, 1.18; women, 1.08). Of the areas where poor whites were studied, Detroit had the highest standardized mortality ratios (men, 2.01; women, 1.90). On the Lower East Side of Manhattan, in Appalachia, and in Northeast Alabama, the ratios for whites were below the national average for blacks (men, 1.90; women, 1.95). CONCLUSIONS: Although differences in mortality rates before the age of 65 between advantaged and disadvantaged groups in the United States are sometimes vast, there are important differences among impoverished communities in patterns of excess mortality.     

Ethnicity and body dissatisfaction among women in the United States: A meta-analysis.

The prevailing view in popular culture and the psychological literature is that White women have greater body dissatisfaction than women of color. In this meta-analysis, 6 main effect sizes were obtained for differences among Asian American, Black, Hispanic, and White women with a sample of 98 studies, yielding 222 effect sizes. The average d for the White-Black comparison was 0.29, indicating that White women are more dissatisfied, but the difference is small. All other comparisons were smaller, and many were close to zero. The findings directly challenge the belief that there are large differences in dissatisfaction between White and all non-White women and suggest that body dissatisfaction may not be the golden girl problem promoted in the literature. Implications for theory and treatment are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Trends in HIV incidence among young adults in the United States

CONTEXT: Behaviors that result in potential exposure to human immunodeficiency virus (HIV) usually begin in adolescence or young adulthood, but trends in HIV incidence in young people remain unclear. OBJECTIVE: To estimate trends in HIV incidence in teenagers and young adults. DESIGN AND SETTING: Back-calculation of past HIV incidence in persons born between 1960 and 1974 using US national acquired immunodeficiency syndrome (AIDS) incidence data and estimates of the distribution of times between HIV infection and AIDS. MAIN OUTCOME MEASURES: Incidence and prevalence of HIV in 1988 and 1993 in persons aged 20 and 25 years, respectively, in each of those years. RESULTS: As of January 1993, about 22000 men and 11000 women aged 18 to 22 years were living with HIV infection in the United States. Homosexual contact was the leading route of infection among young men. Heterosexual contact was the leading route of infection among young women. The HIV incidence attributed to homosexual contact or injection drug use decreased among persons aged 20 and 25 years between 1988 and 1993, but HIV incidence attributed to heterosexual contact was stable or increasing. Notably, in men aged 20 and 25 years, HIV prevalence declined by about 50% in white men but was relatively stable in black and Hispanic men. In contrast, HIV prevalence in women aged 20 and 25 years rose by 36% and 45%, respectively, because of increasing heterosexual transmission. Overall, HIV prevalence in persons aged 20 and 25 years declined by only 14% between 1988 and 1993. CONCLUSIONS: In young persons, HIV incidence in homosexual men and injection drug users was slowing by 1993; this favorable trend was offset by increasing heterosexual transmission, especially in minorities.     

Psychological organizations in the United States.

The organizations to which psychologists belonged at the turn of the 20th century were identified. The attributes of the meetings and the membership of those organizations were compared and discussed. In addition to the American Psychological Association, psychologists belonged to the American Philosophical Association and the American Association for the Advancement of Science as well as to local and regional organizations. In addition, some psychologists belonged to the Society of Experimental Psychology, but membership in that organization was by invitation only. The topics presented at the meetings of the psychological and philosophical associations often were identical or very similar, and the clear disciplinary separation that is typical in 2000 was rare in 1900.

Engineering psychology in the United States.

Describes the origins and history of engineering psychology noting the successes: (1) Explosive expansion and growth, (2) a wide range of research efforts and engineering applications, (3) interest and acceptance by engineering associates, (4) an increasing number of graduate training programs in departments of psychology as well as schools of engineering, and (5) general benefits to psychology as a science and profession. The deficiencies in engineering psychology are attributed to too great an involvement between art and science. (20 ref.) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

An effective analytical psychotherapy in crosscultural context. An East Asian student in the United States

Nucleoside triphosphate hydrolase is an abundant protein secreted by the obligate protozoan parasite Toxoplasma gondii. The protein has apyrase activity, degrading ATP to the di- and mono-phosphate forms. Because T. gondii is incapable of de novo synthesis of purines, it is postulated that NTPase may be used by the parasite to salvage purines from the host cell for survival and replication. To elucidate the molecular mechanisms of NTP gene expression, we isolated from the virulent RH strain of T. gondii the putative promoter region of three tandemly repeated NTP genes (NTP1, 2, 3). Using deletion constructs linked to the chloramphenicol acetyl transferase (CAT) reporter gene, we defined an active promoter within the first 220 bp. Sequence analysis of this region reveals the lack of a TATA box, but the promoter region is associated with a sequence which resembles an initiator element (Inr) in the NTP1 and NTP3 genes. This sequence which is similar to other Inrs known to regulate the expression of a wide variety of RNA polymerase II genes, is required for NTP expression. The NTP3 promoter contains sufficient information for developmentally regulated expression of CAT activity when the actively replicating stage tachyzoite differentiates into the dormant bradyzoite form.     

Clonal relationships among high-level penicillin-resistant Streptococcus pneumoniae in the United States

Emu antibody responses to avian influenza virus (AIV) infection were evaluated by the competitive enzyme-linked immunosorbent assay (C-ELISA), agar gel immunodiffusion (AGID) and hemagglutination inhibition (HI) tests. All birds infected with AIV H5N1, H5N3, or H7N7 developed antinucleoprotein (NP) antibodies as early as 7 days postinfection as detected by the C-ELISA. The responses lasted 49 days for the emus receiving H5N3 and at least 56 days for emus receiving the other two viruses. By evaluating 50 emu field serum samples, the C-ELISA was found more sensitive than the AGID test for the detection of anti-NP antibodies. This study indicates that emus experimentally infected with AIV developed antibody responses that can be detected by C-ELISA, AGID, and HI tests. The results from this and our previous studies demonstrate the use of the C-ELISA as a substitute for the AGID test in a routine serodiagnostic screening for detection of antibodies to AIV infection in multiple avian species.     

Vascular access survival among incident hemodialysis patients in the United States

OBJECTIVES: To investigate: (i) if early psychosocial intervention after cystectomy for bladder cancer can assist psychosocial rehabilitation; (ii) if the outcome of such intervention correlates with the patient's psychological defensive strategies as revealed with the meta-contrast technique (MCT); and (iii) if the patient's general philosophical outlook is important in this context. PATIENTS AND METHODS: Of 50 patients who had undergone radical cystectomy for bladder cancer, 17 received an ileal conduit, 17 a continent urinary reservoir with abdominal stoma and 16 an orthotopic neobladder. Twenty-four of the patients were randomized to psychosocial intervention, comprising weekly counselling 4-9 weeks after surgery. All patients were then evaluated with the Sickness-Impact Profile (SIP) standard questionnaire and the MCT (a projective test of percept-genetic model) was used to reflect individual defensive strategies at the subconscious or unconscious level. The patient's general philosophical outlook was recorded before and after surgery. RESULTS: There was no significant difference in the results of the SIP between the intervention and the non-intervention group, as a whole or in its psychosocial dimension. However, intervention benefited patients with continent cutaneous diversion, whose scores on the psychosocial SIP dimension were lower than in the groups with ileal conduit diversion or orthotopic bladder replacement (P < 0.05). The MCT analysis of defensive strategies identified three clusters of patients characterized mainly by isolation and repression, repression and stereotypy or sensitivity and stereotypy. Analysis for cluster identification showed no significant SIP score differences between intervention and non-intervention groups. In an analysis of single defensive strategies, stereotypy was associated with higher total SIP score, but not significantly. Three clusters of philosophical outlook were identified; in one cluster, characterized by a belief in a supernatural power and philosophical interest, the psychosocial SIP scores were lower in the patients who obtained emotional support and the reverse in a cluster with contrary attitudes, although neither differences were significant. CONCLUSION: Psychosocial intervention assisted the psychosocial rehabilitation of patients with continent cutaneous urinary diversion. Defensive strategies and philosophical outlook generally did not influence the outcome of intervention. However, such programmes may be helpful for some patients, mainly those with a basically pessimistic disposition, a general interest in philosophical questions and often using defensive strategies of stereotypy and repression.     

Psychologists in industry in the United States.

There are "at least 1,000 psychologists today, as compared with less than two dozen some 30 years ago, who devote full time to employment in industry." Their activities are diverse and are discussed under the following major headings: Personnel Selection (Employee selection and assignment, Executive selection, Criterion research); Personnel Development (Appraisal, Employee training, Management development, Counselling); Human Factors in Design (Equipment design, Product design); Productivity; Management; and Miscellaneous. "Psychologists are performing a variety of functions for industry. No one person is engaged in all of these activties." (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A meta-analysis of non-Hodgkin's lymphoma among farmers in the central United States

A meta-analysis of studies examining the association between non-Hodgkin's lymphoma (NHL) and employment as a farmer in the central United States was performed to verify the observation by Blair et al. [1993] that this group is at excess risk of NHL. Six studies were selected for the meta-analysis, and the estimator of relative risk calculated was 1.34 (95% confidence interval (CI) = 1.17, 1.55). Exposures associated with NHL and associated with agricultural commodities frequently produced in the central United States are infectious microorganisms and pesticides. Examination of the production patterns of the farms in this region did not reveal a single specific risk factor consistently found on all farms; however, past production patterns suggest that exposure to either infectious microorganisms or pesticides might be a risk factor for NHL in this group of farmers.     

Epidemiology of extrapulmonary tuberculosis among persons with AIDS in the United States

We compared the antihypertensive efficacy of once-daily amlodipine (AM) versus nitrendipine (NTR) by 24-h ambulatory blood pressure monitoring (24-h ABPM) in 32 patients with mild to moderate essential hypertension (EH). After a 2-week single-blind, placebo run-in period, patients were randomized in a double-blind, parallel fashion: 14 received AM 5 mg and 18 NTR 10 mg. After 2 weeks, dose was adjusted if necessary (AM 10 mg or NTR 20 mg) and continued for another 6-week period. At the end of the placebo period and during the last week of treatment, patients underwent 24-h ABPM. Initial office BP mean values were similar in both groups (169.8 +/- 14/102.5 +/- 6 vs. 167.1 +/- 14/98.7 +/- 5 mm Hg, respectively, p = NS). A comparable decrease in office mean values of systolic BP (SBP, -22.3 +/- 13 vs. -19.1 +/- 16 mm Hg) and diastolic BP (DBP, -12.0 +/- 5 vs. -8.1 +/- 8 mm Hg) was observed. Nevertheless, 24-h ABPM mean values differed significantly between patients treated with AM or NTR with regard to 24-h SBP (120.0 +/- 10 vs. 132.5 +/- 1 mm Hg, p = 0.01). Moreover, the average decrease in 24-h SBP (-19.3 +/- 6 vs. -5.2 +/- 11 mm Hg, p = 0.0036) and 24-h DBP (-10.7 +/- 4 vs. -3.7 +/- 6 mm Hg, p = 0.0047) was higher in the AM group, with no changes in 24-h heart rate (HR). At equivalent once-daily dosage, AM was more effective than NTR in decreasing BP assessed by 24-h ABPM.     

Cumulative trauma disorders among apparel manufacturing employees in the southeastern United States

Factors associated with cumulative trauma disorders (CTDs) of the upper extremities were studied retrospectively, using data from three apparel manufacturing plants in the southeastern United States. Reported CTDs among the employees at risk during fiscal years 1991 and 1992 were analyzed focusing on individual and plant variables. Results showed that CTD rates increased from 1991 to 1992 and fluctuated in a cyclical pattern each year, peaking during January, March, and August. Employee age and duration of employment were associated with CTD rates. Employees aged 45 to 49 had higher CTD rates than those in any other age groups. Employees with 1 to 3 years' experience had higher CTD rates than employees with more years of service.

Forced sexual intercourse and associated health-risk behaviors among female college students in the United States.

This study analyzed data from the 1995 National College Health Risk Behavior Survey (NCHRBS) to assess the prevalence of lifetime rape among female college students and to examine the association between rape and health-risk behaviors. The NCHRBS used a mail questionnaire to assess health-risk behaviors among a nationally representative sample of undergraduate students. Twenty percent of female students reported ever having been forced to have sexual intercourse, most often during adolescence. When analyses controlled for demographic characteristics, female students who had ever been raped were significantly more likely than those who had not to report a wide range of health-risk behaviors. These results highlight a need to improve rape prevention and treatment programs for female adolescents. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Mortality attributed to respiratory problems among finisher pigs in the United States

Over a 6-month period, the mean mortality risk (based on 393 operations participating in the United States National Animal Health Monitoring System 1995 National Swine Study, and representing operations with > or = 300 market hogs in 16 states), was 2.3 +/- 0.2% in the grower/finisher production phase (where figures after the +/- represent the standard error of the estimate). Mortality > or = 4% was experienced by 13.5 +/- 2.9% of grower/finisher operations, while 63.6 +/- 5.3% had < or = 2% mortality. To identify factors associated with > or = 4% mortality, stepwise logistic regression [Statistical Analysis Systems, 1989. SAS/STAT User's Guide, Version 6, 4th edn, Vol. 2. SAS Institute, Cary, NC, 794 pp.] was performed twice: once using operations with all mortality rates, and again excluding operations with between 2% and 4% mortality. Final models were run with SUDAAN [Shah, B.V., Barnwell, B.G., Bieler, G.S., 1996. SUDAAN User's Manual, Version 6.40, 2nd edn. Research Triangle Institute, Research Triangle Park, NC, 492 pp.] to take the sample design into account. In addition, SAS and SUDAAN logistic regression models were developed to analyze factors associated with > 2.3% mortality among grower/finisher pigs. Mean weaning age < or = 28 days entered all models as being associated with increased mortality in the grower/finisher unit. Not obtaining all grower/finisher pigs from farrowing units belonging to the operation was associated with > or = 4% mortality among grower/finisher swine. Not typically giving grower/finisher pigs antibiotics or other agents as disease-preventives or growth-promotants in the feed or water, and ranking producer organizations as very or extremely important sources of antibiotic information were associated with < or = 2.3% mortality in the grower/finisher phase.
