Sociodemographic markers and behavioral correlates of sexually transmitted infections in a nonclinical sample of adolescent and young adult women.

BACKGROUND: We examined sociodemographic markers and 3-month behavioral correlates of sexually transmitted infections (STIs) in a nonclinical cross-section of adolescent and young adult women. METHODS: All women (N=2288) enrolled in recruit training for the US Marine Corps during a 1-year period were asked to voluntarily participate in either a cognitive-behavioral, skills-building intervention to prevent STIs and unintended pregnancies or a nutrition and fitness program. Participants (94.2%) completed a self-administered questionnaire and were screened for Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis infection. The present study presents only the baseline data from the larger study. RESULTS: One or more STIs was diagnosed in 14.1% of participants. Results of a logistic-regression model indicated that the presence of an STI at screening was significantly (P or=2 years), frequency of hormonal contraceptive use (never and sometimes), perception that their sex partners had other concurrent sex partners, and the race or ethnicity of their last sex partner (African American and Native American). CONCLUSIONS: The high prevalence of STIs in this nonclinical sample of young women suggests the need for ongoing screening and prevention interventions that target young, healthy, sexually active women.

Improving rescreening in community clinics: does a system approach work?

Community clinics provide inadequate breast cancer screening services to low-income, racially- and ethnically-diverse communities. This study develops and evaluates the effectiveness of multifaceted organizational system interventions--operational assessments, tracking systems, reminder calls, tailored education, physician prompts and a tailored counseling call--on mammography rescreening rates within three community clinics. We used the Chronic Care Model and Put Prevention Into Practice framework to redesign breast screening delivery services within the California Cancer Detection Programs: Every Woman Counts (CDP:EWC), community clinic settings. We used a quasi-experimental design with a random selection of 400 patients at pre-intervention. To establish a post-intervention clinic's rescreening rate a new comparable cross-sectional random sample of 347 women was drawn. Measures A chart abstraction instrument was used to establish clinics' rescreening rates. Subjects participants at pre and post-intervention were low-income women 50 years of age and older who had received normal mammography results and had not been diagnosed with breast cancer in the last five years. General linear mixed model analysis revealed significant improvements for the organizational system redesign condition [pre-intervention rescreening rate: 32.1 percent v. post-intervention rescreening rate 50.2 percent, (p < .001)]. For the organizational system redesign plus tailored counseling call condition, there was maintenance in the rescreening rate following the intervention [pre-intervention: 44.4 percent v. post-intervention: 45.1 percent, (p > 0.05)]. Multilevel interventions directed at redesigning community clinics primary care breast cancer screening services, can improve mammography rescreening rates.

Understanding the demographic characteristics of urban men who have sex with men.

We examined migration, closetedness, and family structure explanations of demographic profiles of urban men who have sex with men (MSM) using data from the Urban Men's Health Study and the Public Use Microdata Sample of the U.S. Census. The data suggested that the demographic profiles of urban MSM reflect a large in-migrating white, often young adult, population without children. Closetedness, an oft-cited bias in MSM population studies, did not significantly impact demographic patterns with minor exceptions. MSM urban subpopulations have demographics that differ substantially from the general population of the cities in which they reside.

Distress and depression in men who have sex with men: the Urban Men's Health Study.

OBJECTIVE: This study estimates the prevalence of depression and describes the correlates and independent associations of distress and depression among U.S. men who have sex with men. METHOD: A household-based probability sample of men who have sex with men (N=2,881) was interviewed between 1996 and 1998 in four large American cities. With cutoff points of 15 and 22 for the Center for Epidemiological Studies Depression Scale, individual correlates and predictors of distress and depression were examined, and multinomial logistic regression was performed. RESULTS: The 7-day prevalence of depression in men who have sex with men was 17.2%, higher than in adult U.S. men in general. Both distress and depression were associated with lack of a domestic partner; not identifying as gay, queer, or homosexual; experiencing multiple episodes of antigay violence in the previous 5 years; and very high levels of community alienation. Distress was also associated with being of other than Asian/Pacific Islander ethnicity and experiencing early antigay harassment. Depression was also associated with histories of attempted suicide, child abuse, and recent sexual dysfunction. Being HIV positive was correlated with distress and depression but not significantly when demographic characteristics, developmental history, substance use, sexual behavior, and current social context were controlled by logistic regression. CONCLUSIONS: Rates of distress and depression are high in men who have sex with men. These high rates have important public health ramifications. The predictors of distress and depression suggest prevention efforts that might be effective when aimed at men who have sex with men.

Mammography rescreening among women of diverse ethnicities: patient, provider, and health care system factors.

This study identified patient, provider, and health care system factors that influenced mammography rescreening among non-insured, racial/ethnic minority women. Data were collected using a stratified-clustered random sample survey of 1,050 women of five racial/ethnic groups (Latina, Chinese, Filipina, African American, and Caucasian) and 102 primary care clinical sites. Women received screening services through two no-cost screening programs in California. Chi-square tests were used to assess bivariate associations and multiple logistic regressions were used to compute adjusted odds ratios and 95% confidence intervals. Mammography rescreening was associated with living in the United States longer; having higher education levels, better health care access, a history of breast problems, and favorable perceptions of mammography; obtaining regular Pap screening and hormone replacement therapy; having had better communication with clinicians; and attending clinics that conducted in-reach activities. This study suggests that simply removing financial barriers is not enough to improve mammography rescreening among underserved women.

Suicide attempts among gay and bisexual men: lifetime prevalence and antecedents.

OBJECTIVES: We examined lifetime prevalence of suicide attempts and psychosocial correlates in a large population-based sample of men who have sex with men (MSM). METHODS: A telephone probability sample of US urban MSM (n = 2881) were interviewed between November 1996 and February 1998. RESULTS: Twenty-one percent had made a suicide plan; 12% had attempted suicide (almost half of those 12% were multiple attempters). Most who attempted suicide made their first attempt before age 25. Although prevalence of parasuicide (i.e., attempted suicide) has remained constant across birth cohorts, mean age at initial attempts has declined. CONCLUSIONS: MSM are at elevated risk for suicide attempts, with such risk clustered earlier in life. Some risk factors were specific to being gay or bisexual in a hostile environment.
