Sleepy Teens and Energy Drink Use: Results From an Ethnically Diverse Sample of Youth.

This study examines the association between use of energy drinks or products (EP), EP expectancies, and the association between EP use and sleep in a racially and ethnically diverse sample (N = 2,485) of adolescents. Prevalence of EP use was approximately 18%, with no statistically significant racial or ethnic differences in prevalence. There were significant racial and ethnic differences in EP expectancies; Hispanic and Multiracial or Other groups endorsed less positive expectancies than Whites and Asians. EP use was significantly associated with later weekend bedtimes, shorter weekend total sleep time (TST), a smaller weekend-weekday difference in TST, and more trouble sleeping, even after adjusting for covariates. There were no significant race or ethnicity interactions between EP use and sleep. EP use is an independent correlate of sleep problems in adolescents across racial or ethnic groups.

Influence of mental health and alcohol or other drug use risk on adolescent reported care received in primary care settings.

BACKGROUND: To describe patterns of alcohol and other drug (AOD) use risk and adolescent reported primary care (PC) screening and intervention, and examine associations of AOD risk and mental health with reported care received. METHODS: We analyzed data from cross-sectional surveys collected from April 3, 2013 to November 24, 2015 from 1279 diverse adolescents ages 12-18 who reported visiting a doctor at least once in the past year. Key measures were AOD risk using the Personal Experience Screening Questionnaire; mental health using the 5-item Mental Health Inventory; binary measures of adolescent-reported screening and intervention. RESULTS: Half (49.2%) of the adolescents reported past year AOD use. Of the 769 (60.1%) of adolescents that reported being asked by a medical provider in PC about AOD use, only 37.2% reported receiving screening/intervention. The odds of reported screening/intervention were significantly higher for adolescents with higher AOD risk and lower mental health scores. CONCLUSIONS: Adolescents at risk for AOD use and poor mental health are most likely to benefit from brief intervention. These findings suggest that strategies are needed to facilitate medical providers identification of need for counseling of both AOD and mental health care for at risk youth.

Predictors of Retention in an Alcohol and Risky Sex Prevention Program for Homeless Young Adults.

Homeless young adults are at risk for alcohol and other drug (AOD) use and risky sexual behavior. Interventions are needed to help these young people reduce their risky behavior, but this population is often difficult to engage and retain in services. We offered a four-session AOD and risky sex reduction program to 100 participants and examined if retention in the program was predicted by a number of factors: demographics, homelessness severity, other service use, AOD behaviors, mental health symptoms, sexual risk behaviors, and readiness to change AOD and condom use. Nearly half (48%) of participants completed all sessions. In bivariate analyses, participants were significantly less likely to be retained in the program if they had slept outdoors in the past month, engaged in more alcohol and marijuana use, experienced more alcohol-related consequences, and received the program in an urban drop-in center (as opposed to a drop-in center near the beach). When controlling for all significant bivariate relationships, only sleeping outdoors and receipt of the program in the urban setting predicted fewer sessions completed. The most endorsed reasons for program non-completion were being too busy to attend and inconvenient day/time of the program. Findings can help outreach staff and researchers better prepare methods to engage higher risk homeless youth and retain them in services. Finding unique ways to help youth overcome barriers related to location of services appears especially necessary, perhaps by bringing services to youth where they temporarily reside or offering meaningful incentives for program attendance.

The Co-evolution of Bullying Perpetration, Homophobic Teasing, and a School Friendship Network.

Bullying and homophobic teasing behaviors affect the lives of many school aged children, often co-occur, and tend to peak in middle school. While bullying and homophobic teasing behaviors are known to be peer group phenomena, studies typically examine the associations at the individual or school levels. An examination of these behaviors at the peer group level can aid in our understanding of the formation and maintenance of peer groups that engage in these forms of aggressive behavior (selection), and the extent to which friends and the peer group impact individual rates of these aggressive behaviors (influence). In this longitudinal study, we assess the co-evolution of friendship networks, bullying perpetration, and homophobic teasing among middle school students (n = 190) using a Stochastic Actor-Based Model (SABM) for longitudinal networks. Data were collected from 6-8th-grade students (Baseline age 12-15; 53% Female; 47% Male) across three waves of data. The sample was diverse with 58% African American, 31% White, and 11% Hispanic. Since bullying and homophobic teasing behaviors are related yet distinct forms of peer aggression, to capture the unique and combined effects of these behaviors we ran models separately and then together in a competing model. Results indicated that on average individuals with higher rates of bullying perpetration and homophobic teasing were associated with becoming increasingly popular as a friend. However, the effects were not linear, and individuals with the highest rates of bullying perpetration and homophobic teasing were less likely to receive friendship nominations. There was no evidence that bullying perpetration or homophobic teasing were associated with the number of friendship nominations made. Further, there was a preference for individuals to form or maintain friendships with peers who engaged in similar rates of homophobic name-calling; however, this effect was not found for bullying perpetration. Additionally, changes in individual rates of bullying perpetration were not found to be predicted by the bullying perpetration of their friends; however, changes in adolescent homophobic teasing were predicted by the homophobic teasing behaviors of their friends. In a competing model that combined bullying perpetration and homophobic teasing, we found no evidence that these behaviors were associated with popularity. These findings are likely due to the high association between bullying perpetration and homophobic teasing combined with the small sample size. However, friendship selection was based on homophobic name-calling, such that, there was a preference to befriend individuals with similar rates of homophobic teasing. We also examined several risk factors (dominance, traditional masculinity, impulsivity, femininity, positive attitudes of bullying, and neighborhood violence), although, impulsivity was the only covariate that was associated with higher levels of bullying perpetration and homophobic teasing. More specifically, youth with higher rates of impulsivity engaged in higher rates of bullying perpetration and homophobic teasing over time. The findings suggest bullying perpetration and homophobic teasing have important influences on friendship formation, and close friendships influence youth's engagement in homophobic teasing. Implications for prevention and intervention efforts are discussed in terms of targeting peer groups and popular peers to help reduce rates of these aggressive behaviors.

Mindfulness Meditation for Chronic Pain: Systematic Review and Meta-analysis.

BACKGROUND: Chronic pain patients increasingly seek treatment through mindfulness meditation. PURPOSE: This study aims to synthesize evidence on efficacy and safety of mindfulness meditation interventions for the treatment of chronic pain in adults. METHOD: We conducted a systematic review on randomized controlled trials (RCTs) with meta-analyses using the Hartung-Knapp-Sidik-Jonkman method for random-effects models. Quality of evidence was assessed using the GRADE approach. Outcomes included pain, depression, quality of life, and analgesic use. RESULTS: Thirty-eight RCTs met inclusion criteria; seven reported on safety. We found low-quality evidence that mindfulness meditation is associated with a small decrease in pain compared with all types of controls in 30 RCTs. Statistically significant effects were also found for depression symptoms and quality of life. CONCLUSIONS: While mindfulness meditation improves pain and depression symptoms and quality of life, additional well-designed, rigorous, and large-scale RCTs are needed to decisively provide estimates of the efficacy of mindfulness meditation for chronic pain.

Assessing and improving organizational readiness to implement substance use disorder treatment in primary care: findings from the SUMMIT study.

BACKGROUND: Millions of people with substance use disorders (SUDs) need, but do not receive, treatment. Delivering SUD treatment in primary care settings could increase access to treatment because most people visit their primary care doctors at least once a year, but evidence-based SUD treatments are underutilized in primary care settings. We used an organizational readiness intervention comprised of a cluster of implementation strategies to prepare a federally qualified health center to deliver SUD screening and evidence-based treatments (extended-release injectable naltrexone (XR-NTX) for alcohol use disorders, buprenorphine/naloxone (BUP/NX) for opioid use disorders and a brief motivational interviewing/cognitive behavioral -based psychotherapy for both disorders). This article reports the effects of the intervention on key implementation outcomes. METHODS: To assess changes in organizational readiness we conducted pre- and post-intervention surveys with prescribing medical providers, behavioral health providers and general clinic staff (N = 69). We report on changes in implementation outcomes: acceptability, perceptions of appropriateness and feasibility, and intention to adopt the evidence-based treatments. We used Wilcoxon signed rank tests to analyze pre- to post-intervention changes. RESULTS: After 18 months, prescribing medical providers agreed more that XR-NTX was easier to use for patients with alcohol use disorders than before the intervention, but their opinions about the effectiveness and ease of use of BUP/NX for patients with opioid use disorders did not improve. Prescribing medical providers also felt more strongly after the intervention that XR-NTX for alcohol use disorders was compatible with current practices. Opinions of general clinic staff about the appropriateness of SUD treatment in primary care improved significantly. CONCLUSIONS: Consistent with implementation theory, we found that an organizational readiness implementation intervention enhanced perceptions in some domains of practice acceptability and appropriateness. Further research will assess whether these factors, which focus on individual staff readiness, change over time and ultimately predict adoption of SUD treatments in primary care.

Gender differences in the association between conduct disorder and risky sexual behavior.

Despite suggestions that there are gender differences in the association between conduct disorder (CD) and risky sexual behavior, limited empirical research has examined this question. Youth (N = 616) were recruited from four primary care clinics and completed questions related to risky sexual behavior, alcohol and marijuana use, and CD. Results of stratified multivariate models indicated that the association between CD and having four or more lifetime partners, having two or more partners in the last 3 months, and engaging in condomless sex was stronger among female youth. However, the association between CD and alcohol and other drug use before sex was stronger in male youth. This is an important contribution to our understanding of gender-specific manifestations of conduct disorder, and has the potential to inform screening and brief intervention efforts for this population.

Electronic health record-based interventions for improving appropriate diagnostic imaging: a systematic review and meta-analysis.

BACKGROUND: One driver of increasing health care costs is the use of radiologic imaging procedures. More appropriate use could improve quality and reduce costs. PURPOSE: To review interventions that use the computerized clinical decision-support (CCDS) capabilities of electronic health records to improve appropriate use of diagnostic radiologic test ordering. DATA SOURCES: English-language articles in PubMed from 1995 to September 2014 and searches in Web of Science and PubMed of citations related to key articles. STUDY SELECTION: 23 studies, including 3 randomized trials, 7 time-series studies, and 13 pre-post studies that assessed the effect of CCDS on diagnostic radiologic test ordering in adults. DATA EXTRACTION: 2 independent reviewers extracted data on functionality, study outcomes, and context and assessed the quality of included studies. DATA SYNTHESIS: Thirteen studies provided moderate-level evidence that CCDS improves appropriateness (effect size, -0.49 [95% CI, -0.71 to -0.26]) and reduces use (effect size, -0.13 [CI, -0.23 to -0.04]). Interventions with a "hard stop" that prevents a clinician from overriding the CCDS without outside consultation, as well as interventions in integrated care delivery systems, may be more effective. Harms have rarely been assessed but include decreased ordering of appropriate tests and physician dissatisfaction. LIMITATION: Potential for publication bias, insufficient reporting of harms, and poor description of context and implementation. CONCLUSION: Computerized clinical decision support integrated with the electronic health record can improve appropriate use of diagnostic radiology by a moderate amount and decrease use by a small amount. Before widespread adoption can be recommended, more data are needed on potential harms. PRIMARY FUNDING SOURCE: U.S. Department of Veterans Affairs. (PROSPERO registration number: CRD42014007469).

To Educate or To Incarcerate: Factors in Disproportionality in School Discipline.

The school-to-prison pipeline describes the process by which school suspension/expulsion may push adolescents into the justice system disproportionately based on race/ethnicity, socioeconomic status, and gender. The current study moves the field forward by analyzing a survey of a diverse sample of 2,539 students in 10th to 12th grade in Southern California to examine how demographic, individual, and family factors contribute to disparities in office referral and suspension/expulsion. African Americans, boys, and students whose parents had less education were more likely to be suspended/expelled. Higher levels of student academic preparation for class, hours spent on homework, and academic aspiration were associated with less school discipline. Findings suggest that helping students engage in school may be protective against disproportionate school discipline.

Motivation to Quit and Interest in Cessation Treatment Among Homeless Youth Smokers.

INTRODUCTION: Approximately 70% of unaccompanied homeless youth are current smokers. Although a few studies have described smoking behavior among homeless youth, none have focused on how to help homeless youth quit smoking. As such, there are significant gaps in understanding their interest in quitting and what strategies might best fit their specific needs. METHODS: Unaccompanied homeless youth were randomly sampled from street sites in Los Angeles County (N = 292). All were current smokers who completed a survey on their smoking-related behaviors and cognitions. RESULTS: 65.7% of youth had quit for at least 24hr during the past year, and 43.4% were motivated to quit. Previous quit attempts tended to be unassisted, but 58.6% reported that they would be interested in formal cessation treatment. Multivariate analyses indicated that motivation to quit was higher among youth who were older, Black or Hispanic (vs. White), and who asked about smoking by a service provider, but it was lower among those who were more nicotine dependent. Being interested in cessation treatment was more likely among youth who were asked about smoking by a service provider, anticipated more barriers to quitting, and were motivated to quit; it was less likely among youth who had slept outdoors during the past 30 days. DISCUSSION: Smoking cessation is often considered a low priority for homeless youth. However, many are motivated to quit and are interested in smoking cessation products and services. Implications for developing and engaging homeless youth in cessation treatment are discussed.

The effects of mental health symptoms and marijuana expectancies on marijuana use and consequences among at-risk adolescents.

Based on expectancy theory, adolescents at risk for mental health symptoms, such as those involved in the juvenile court system, may use marijuana due to the belief that use will attenuate anxiety and depressive symptoms. In a diverse sample of youth involved in the Santa Barbara Teen Court system (N = 193), we examined the association between mental health symptoms and marijuana expectancies on marijuana use and consequences. In general, stronger positive expectancies and weaker negative expectancies were both associated with increased marijuana use. Youth that reported more symptoms of both anxiety and depression and stronger positive expectancies for marijuana also reported more consequences. We found that youth experiencing the greatest level of consequences from marijuana were those that reported more depressive symptoms and stronger positive expectancies for marijuana. Findings suggest that these symptoms, combined with strong positive expectancies about marijuana's effects, have implications for consequences among at-risk youth.

Consequences of interstitial cystitis/bladder pain symptoms on women's work participation and income: results from a national household sample.

PURPOSE: We describe differences in work participation and income by bladder symptom impact and comorbidities among women with interstitial cystitis/bladder pain syndrome. MATERIALS AND METHODS: Cross-sectional data from 2,767 respondents younger than 65 years identified with interstitial cystitis/bladder pain syndrome symptoms were analyzed. The data were taken from the RAND Interstitial Cystitis Epidemiology (RICE) survey, and included retrospective self-reports of interstitial cystitis/bladder pain syndrome impact, severity, years since onset, related comorbidities (depressive symptomatology, number of conditions), work participation and income, and personal characteristics. Multiple regressions predicted 5 current work outcomes of works now, kept from working by pain, missed work days, days worked when bothered by symptoms and real income change since symptom onset. RESULTS: Controlling for work status at symptom onset and personal characteristics, greater bladder symptom impact predicted a greater likelihood of not now working, kept more days from working by pain, missed more work days and working more days with symptoms. More depressive symptomatology and greater number of comorbidities predicted reduced work participation. Women experienced no growth in real income since symptom onset. Measures of symptom severity were not associated with any of the economic outcomes. CONCLUSIONS: Greater interstitial cystitis/bladder pain syndrome symptom impact, depressive symptomatology and count of comorbidities (but not symptom severity) were each associated with less work participation and leveling of women's long-term earnings. Management of bladder symptom impact on nonwork related activities and depressive symptomatology may improve women's work outcomes.

To use or not to use: a stage-based approach to understanding condom use among homeless youth.

This study used a stage-based approach to understand condom use behavior in a representative sample of 309 sexually active homeless youth recruited from shelters, drop-in centers, and street sites in Los Angeles County. Focusing on the youth's most recent sexual event, the three stages of condom use examined were: (1) whether the partners decided prior to the event about using condoms; (2) whether a condom was available at the event; and (3) whether a condom was used at the event. Logistic regression analysis was used to identify attitudinal, relationship, and contextual correlates of each of these three stages. Deciding ahead of time about condom use was associated with being Hispanic, level of education, condom attitudes, and various relationship characteristics (e.g., partner type, monogamy, relationship abuse), with the nature of these associations varying depending on the type of decision (i.e., deciding to use, deciding to not use). Condom availability was more likely to be reported by males, if the event was described as being special in some way, or if the event lacked privacy. Condom use was more likely among youth with more positive condom attitudes and among youth who decide ahead of time to use a condom, but less likely among those in monogamous relationships or when hard drugs were used prior to sex. Whether sexual intercourse is protected or unprotected is the end result of a series of decisions and actions by sexual partners. Results from this study illustrate how condom use can be better understood by unpacking the stages and identifying influential factors at each stage. Each stage may, in and of itself, be an important target for intervention with homeless youth.

Alternative tobacco product use and smoking cessation among homeless youth in los angeles county.

INTRODUCTION: Approximately 70% of homeless youth smoke cigarettes, but their use of alternative tobacco products (ATPs) is unknown. This paper reports on ATP use among past-month smokers in Los Angeles County, including whether it differs by demographic characteristics, homelessness severity, past-year quit attempts, and readiness to quit smoking. Given the growing popularity of e-cigarettes, we also report on perceptions of harm and reasons for using this product. METHODS: We surveyed 292 unaccompanied homeless youth who were randomly sampled from street sites. Participants had smoked at least 100 cigarettes during their lifetime and 1 cigarette during the past month. RESULTS: Seventy-two percent of youth reported past-month ATP use (e-cigarettes = 51%; little cigars/cigarillos = 46%; hookah = 31%; other smokeless tobacco product = 24%; chewing tobacco/moist snuff = 19%). Current ATP use was unrelated to most demographic characteristics or having a past-year quit attempt. However, youth who planned to quit smoking in the next 30 days were significantly less likely to report current use of hookahs, other smokeless tobacco products, or e-cigarettes. Among lifetime e-cigarette users, the most common reasons for use included not having to go outside to smoke (38%) and being able to deal with situations or places where they cannot smoke (36%); it was less common to report using e-cigarettes to quit smoking (17%-18%). DISCUSSION: Dual use of ATPs among homeless youth smokers is common and is more likely among those who have no immediate plans to quit smoking. Effective and easily disseminable strategies for reducing all forms of tobacco use among homeless youth are urgently needed.

Predisposing, enabling and need correlates of mental health treatment utilization among homeless men.

There is significant unmet need for mental health treatment among homeless men, but little is known about the correlates of treatment utilization in this population. Within the framework of the Behavioral Model for Vulnerable Populations, this study examines predisposing, enabling and need factors that may be associated with mental health care utilization. Participants were a representative sample of 305 heterosexually active homeless men utilizing meal programs in the Skid Row region of LA. Logistic regression examined the association between predisposing, enabling and need factors and past 30 day mental health service utilization on Skid Row. Results indicated that while need, operationalized as positive screens for posttraumatic stress disorder or depression, was associated with recent mental health care utilization, predisposing and enabling factors were also related to utilization. African-American homeless men, and those men who also reported substance abuse treatment and drop-in center use, had increased odds of reporting mental health care utilization.

Orthopaedic Surgery and Indusry: What our Potential Patients Believe.

PURPOSE: Physician and surgeon involvement in industry has received considerable attention in recent decades. In this study, we outline the perspective of the general US population regarding (1) disclosure, (2) ownership, and (3) compensation between physicians/surgeons and industry. We hypothesize that the general population would be largely supportive of the physician/surgeon-industry relationship. METHODS: An online, survey-based, descriptive study was conducted through a crowdsourcing platform, Amazon Mechanical Turk. Survey respondents were presented with a seven-item questionnaire inquiring about the physician/surgeon and industry relationship. An "attention check" question was included; those who failed this question were excluded. Descriptive statistics were used to assess the data and a McNemar chi-squared test for paired, dichotomous data. RESULTS: A total of 993 respondents were included. Survey responses are summarized in Table 1. 70.6% of respondents stated that it was "important" or "extremely important" to disclose that the patient be informed whether implants used in surgery had been developed by the operating surgeon. 71.1% of respondents reported that it was "important" or "extremely important" to disclose partial ownership within industry. Seventy-one percent of respondents stated it was "important" or "extremely important" to disclose royalty payments pertaining to surgical implants. 95.6% of respondents suggested that it was acceptable for surgeons to accept free airfare and lodging, and 95.2% of respondents stated that it was acceptable for the surgeon to be compensated for time away from practice to learn about new equipment. DISCUSSION: In our survey of 993 respondents, we found that relationships with industry are considered acceptable if appropriate disclosure is given to patients. We also found that although respondents suggested that physicians and surgeons may be influenced by a free meal, compensation for trips to try new equipment and time spent away from practice is considered appropriate. LEVEL OF EVIDENCE: 2c, Ecological studies.

Proximal humerus open reduction internal fixation with and without biceps tenodesis: assessment of early clinical outcomes.

Background: The role of biceps tenodesis (BT) during open reduction internal fixation (ORIF) of proximal humerus fractures (PHFs) remains unclear. A subset of patients undergoing ORIF have persistent pain with unclear etiology. The purpose of our study was to compare outcomes of ORIF of PHFs with and without concomitant BT. We hypothesize patients undergoing BT at the time of ORIF will have improved patient-reported outcome scores with fewer secondary procedures related to treatment of the biceps. Methods: In this retrospective cohort study, all patients undergoing ORIF for a PHF at a single level one trauma center from January 2019 to June 2022 were reviewed. Patients under the age of 18 were excluded. Primary outcomes were patient-reported outcomes measurement information system physical function, depression, and pain interference scores at 5 time points up to final follow-up. Secondary outcomes included total operative time, complications, subsequent procedures, steroid injections, and range of motion. Chi-square tests were performed for categorical values and paired t-tests for continuous variables. Results: 71 patients met inclusion criteria: 41 undergoing ORIF without BT and 30 undergoing ORIF with BT. Average follow-up was 11 months. There were no statistically significant differences in patient demographics between groups. There were no differences in patient-reported outcomes measurement information system scores at any time point postoperatively. At final follow-up patients in the ORIF with BT group had higher forward flexion than those who did not undergo BT (142 vs. 123 degrees, respectively, P < .02). There were no differences in surgical time, revision rates, postsurgical complications, or postoperative injections between groups. Conclusion: BT performed during ORIF of PHFs did not result in significantly different functional or patient-reported outcomes between groups, except for greater forward flexion at final follow-up. Although BT was done more commonly in severe PHFs, patients in both groups had similar rates of subsequent biceps-related procedures and revision surgery.

Radiographic Accuracy of Identifying Anterolateral Tibial Plafond Involvement in Pronation Abduction Ankle Fractures.

OBJECTIVES: To evaluate the incidence of anterolateral tibial plafond involvement in pronation-abduction (PAB) ankle fractures and analyze the accuracy of radiographs in detecting anterolateral tibial plafond involvement, impaction, and predicting the need for direct visualization and an articular reduction. METHODS: Design: A multi-institutional retrospective chart review. SETTING: Five level 1 trauma centers in the United States. PATIENT SELECTION CRITERIA: Adult patients with PAB ankle fractures (OTA/AO 44B2.3, 44C2.2, 44C2.3) from 2020-2022 were reviewed by 7 fellowship-trained orthopedic trauma surgeons. They were queried about the presence of anterolateral tibial plafond involvement and impaction, and whether they would need direct visualization and an articular reduction using both radiographs and CT. OUTCOME MEASUREMENTS AND COMPARISONS: The presence of anterolateral tibial plafond impaction was tabulated separately using radiographs and CT scans. The accuracy of radiographs and changes in surgical plan after CT review were calculated using CT as the gold standard. RESULTS: 61 fractures in 61 patients were evaluated with CT and/or plain radiographs. Using plain radiographs, anterolateral tibial plafond involvement and impaction were identified in 61% and 36% of cases, respectively. In the 38 fractures with both plain radiographs and CT scans, anterolateral tibial plafond involvement was identified in 66% of radiographs and 74% of CT scans (p = 0.4). Plafond impaction was identified in 42% of plain radiographs and 37% of CT scans (p = 0.62). There was no difference in the rate of involvement between radiographs and CT scan. The diagnosis of anterolateral tibial plafond impaction using plain radiographs was correct in 74% of fractures when compared to CT imaging, resulting in a sensitivity of 71%, a specificity of 75%, a positive predictive value (PPV) of 62%, and a negative predictive value (NPV) of 82%. Plain radiographs correctly predicted the need for direct visualization and an articular reduction in 74% of cases and had a PPV of 59% and a NPV of 86%. CONCLUSIONS: Anterolateral tibial plafond involvement and impaction was present on CT in 74% and 37% of pronation-abduction (PAB) ankle fractures, respectively. Plain radiographs had higher NPV for identifying impaction and the need for articular reduction than they did sensitivity, specificity or PPV. CT is an important tool for preoperative planning that should be considered when planning for operative fixation of PAB ankle fractures. LEVEL OF EVIDENCE: Prognostic level III.

The prevalence and overlap of interstitial cystitis/bladder pain syndrome and chronic prostatitis/chronic pelvic pain syndrome in men: results of the RAND Interstitial Cystitis Epidemiology male study.

PURPOSE: As part of the RICE (RAND Interstitial Cystitis Epidemiology) study, we developed validated case definitions to identify interstitial cystitis/bladder pain syndrome in women and chronic prostatitis/chronic pelvic pain syndrome in men. Using population based screening methods, we applied these case definitions to determine the prevalence of these conditions in men. MATERIALS AND METHODS: A total of 6,072 households were contacted by telephone to screen for men who had symptoms of interstitial cystitis/bladder pain syndrome or chronic prostatitis/chronic pelvic pain syndrome. An initial 296 men screened positive, of whom 149 met the inclusionary criteria and completed the telephone interview. For interstitial cystitis/bladder pain syndrome 2 case definitions were applied (1 with high sensitivity and 1 with high specificity), while for chronic prostatitis/chronic pelvic pain syndrome a single case definition (with high sensitivity and specificity) was used. These case definitions were used to classify subjects into groups based on diagnosis. RESULTS: The interstitial cystitis/bladder pain syndrome weighted prevalence estimates for the high sensitivity and high specificity definitions were 4.2% (3.1-5.3) and 1.9% (1.1-2.7), respectively. The chronic prostatitis/chronic pelvic pain syndrome weighted prevalence estimate was 1.8% (0.9-2.7). These values equate to 1,986,972 (95% CI 966,042-2,996,924) men with chronic prostatitis/chronic pelvic pain syndrome and 2,107,727 (95% CI 1,240,485-2,974,969) men with the high specificity definition of interstitial cystitis/bladder pain syndrome in the United States. The overlap between men who met the high specificity interstitial cystitis/bladder pain syndrome case definition or the chronic prostatitis/chronic pelvic pain syndrome case definition was 17%. CONCLUSIONS: Symptoms of interstitial cystitis/bladder pain syndrome and chronic prostatitis/chronic pelvic pain syndrome are widespread among men in the United States. The prevalence of interstitial cystitis/bladder pain syndrome symptoms in men approaches that in women, suggesting that this condition may be underdiagnosed in the male population.

Understanding heterosexual condom use among homeless men.

This study uses an event-based approach to examine individual, relationship, and contextual correlates of heterosexual condom use among homeless men. Structured interviews were conducted with a predominantly African American sample of 305 men recruited from meal lines in the Skid Row area of Los Angeles. Men reported on their most recent heterosexual event involving vaginal or anal intercourse. Adjusting for demographic characteristics only, condom use was more likely when men had higher condom use self-efficacy, greater HIV knowledge, or talked to their partner about condoms prior to sex. Condom use was less likely when men held more negative attitudes towards condoms, the partner was considered to be a primary/serious partner, hard drug use preceded sex, or sex occurred in a public setting. Condom attitudes, self-efficacy, partner type, and communication were the strongest predictors of condom use in a multivariate model that included all of the above-mentioned factors. Associations of unprotected sex with hard drug use prior to sex and having sex in public settings could be accounted for by lower condom self-efficacy and/or less positive condom attitudes among men having sex under these conditions. Results suggest that it may be promising to adapt existing, evidence-based IMB interventions for delivery in non-traditional settings that are frequented by men experiencing homelessness to achieve HIV risk reduction and thus reduce a significant point of disparity for the largely African American population of homeless men.
