Ethics guidelines for environmental epidemiologists: 2023 revision.

Recognition of the importance to environmental epidemiology of ethical and philosophical deliberation led, in 1996, to the establishment of Ethics Guidelines for the profession. In 1999, these guidelines were adopted by the International Society for Environmental Epidemiology. The guidelines were revised in 2012 and again in 2023 to ensure continued relevance to the major issues facing the field. Comprising normative standards of professional conduct, the guidelines are structured into four subsections: (1) obligations to individuals and communities who participate in research; (2) obligations to society; (3) obligations regarding funders/sponsors and employers; and (4) obligations to colleagues. Through the 2023 revision of the Ethics Guidelines, the International Society for Environmental Epidemiology seeks to ensure the highest possible standards of transparency and accountability for the ethical conduct of environmental epidemiologists engaged in research and public health practice.

Linking peers, patients, and providers: a qualitative study of a peer integration program for hard-to-reach patients living with HIV/AIDS.

For HIV-positive individuals living in socially vulnerable circumstances, the complexities of accessing and navigating healthcare system can be overwhelming. Peer-driven interventions (PDIs) are increasingly being recognized as effective ways of addressing barriers to HIV care in the USA. The present study is a qualitative investigation of barriers, challenges, and facilitators to implementation of a peer integration program at three health centers in the USA. Findings reveal that health center staff and HIV-positive patients support the integration of HIV-positive peers on multidisciplinary healthcare teams. However, challenges related to peer-clinician communication and the risk of emotional burnout for peers may hinder program efficacy and sustainability. Practical implications and suggestions for improving the peer integration program in light of these findings are also discussed.

Sexual risk behavior and symptoms of historical loss in American Indian men.

Native Americans in the United States are not typically regarded as a most at-risk population for HIV or other sexually transmitted infections (STIs), despite emerging evidence which suggests otherwise. As a result, Native Americans lack access to key prevention services and programs. In planning prevention programs for this unique population, however, it is important to take into account the cultural factors that may be implicated in health risk behaviors. Historical Loss is a type of historical trauma that has been reported in Native Americans, and which may be related to health behaviors. We examined whether Historical Loss was associated with sexual risk behaviors in a sample of 120 American Indian men living in Fort Peck Reservation in northeastern Montana who completed questions regarding Historical Loss and sexual risk behaviors. Symptoms of Historical Loss that reflected Anxiety/Depression and Anger/Avoidance were associated with an increased likelihood of individuals' having sex with multiple concurrent partners. Health interventions that aim to address HIV/STI prevention should take symptoms of Historical Loss into account, as Historical Loss could be a potential factor that will mitigate HIV, STI, and pregnancy prevention efforts in this population.

Condom use following a pilot test of the Popular Opinion Leader intervention in the Barbados Defence Force.

Worldwide, military personnel have been recognized as a population at elevated risk for sexually transmitted infections and HIV. However, few evidence based behavioral interventions for the prevention of HIV and STIs have been rigorously evaluated in military personnel. We adapted the Popular Opinion Leaders (POL) intervention and piloted the adapted program with the Barbados Defence Force at one military base in Barbados. Popular Opinion Leaders were selected and trained to focus conversations on condom use. Behavioral questionnaires were administered using audio computer-assisted self interview at baseline (n = 256) and 6-month follow-up (n = 303). Mid-point focus groups were conducted with a sample of 15 POLs at a 3 month mid-point assessment. Quantitative data showed moderate increases in condom use at 6-months, and significant uptake of condom use during oral-genital contact in female personnel. A subgroup analysis suggests that this change was partially mediated by post-intervention changes in injunctive norms surrounding condom use in women. Focus groups revealed that POLs were heavily focusing on condom demonstrations, condom provision within social networks, speaking with coworkers about pleasure associated with condom use, and that the most common venues for conversations included those where alcohol was consumed. During the intervention, POLs dispersed from the intervention site as a result of normal personnel movement across bases, resulting in our having to use a pre and post intervention design across the population. It is likely that larger effect sizes would be observed in efforts that account for the natural dispersion of personnel across bases.

Toward a social theory of sexual risk behavior among men in the Armed Services: understanding the military occupational habitus.

Worldwide, military personnel have been recognized as a population at elevated risk for sexually transmitted infections (STIs) and HIV; however, it is not well understood how the military occupation itself is implicated in the production of sexual risk behavior. Using qualitative and quantitative data collected from the Belize Defense Force (BDF), we employed a grounded theoretical framework and the Bourdieusian concept of the field and habitus to clarify how the military occupation is implicated in structuring aspects of sexual risk behaviors among personnel. We focus results on in-depth qualitative interviews conducted with 15 male-identified BDF personnel. We identify and describe how two field elements, namely operational tempo and ongoing exposure to occupational hazards, are occupationally specific field elements implicated in the production of sexual risk behavior through the mediating matrix of the military class habitus. Our findings demonstrate a conceptual clarity regarding the institutional field and habitus through which military personnel make sense of and act on the risk of bodily harm with regard to their own sexual behaviors. We conclude by outlining our theoretical concept so that it can be directly applied in public health efforts in order to leverage military occupational field elements for the purpose of HIV and STI prevention.

Indigenous standpoint theory as a theoretical framework for decolonizing social science health research with American Indian communities.

Theoretical frameworks rooted in Western knowledge claims utilized for public health research in the social sciences are not inclusive of American Indian communities. Developed by Indigenous researchers, Indigenous standpoint theory builds from and moves beyond Western theoretical frameworks. We argue that using Indigenous standpoint theory in partnership with American Indian communities works to decolonize research related to American Indian health in the social sciences and combats the effects of colonization in three ways. First, Indigenous standpoint theory aids in interpreting how the intersections unique to American Indians including the effects of colonization, tribal and other identities, and cultural context are linked to structural inequalities for American Indian communities. Second, Indigenous standpoint theory integrates Indigenous ways of knowing with Western research orientations and methodologies in a collaborative process that works to decolonize social science research for American Indians. Third, Indigenous standpoint theory promotes direct application of research benefits to American Indian communities.

Sexual risk behavior among military personnel stationed at border-crossing zones in the Dominican Republic.

OBJECTIVE: To estimate the prevalence of sexual risk behaviors among military personnel stationed along major border-crossing zones between the Dominican Republic and Haiti. METHODS: From November 2008 to January 2009, behavioral surveys were administered to 498 active duty military personnel stationed along the three largest border-crossing zones on the western border of the Dominican Republic. Participants were selected using systematic random sampling and asked about their sexual behavior over the past 12 months, alcohol use, and mental health. RESULTS: Forty-one percent reported having casual sex during the past 12 months, 37% of men had a history of having sex with a commercial sex worker (19% during the past 12 months), and 7% of men reported a history of having sex with a transmigrating Haitian (6% during the past 12 months). Among sexually non-monogamous respondents (51%), inconsistent condom use exceeded 60% for those engaging in anal, vaginal, or oral sex. Fifteen percent reported using sexual coercion during the past 12 months. CONCLUSIONS: Sexual risk behaviors were prevalent among military personnel stationed along border-crossing zones between the Dominican Republic and Haiti. Prevention programs targeted at military personnel in this region should incorporate sexual coercion and mental health as key elements of their HIV prevention programs.

A needs assessment of clients with HIV in a home-based care program in Guyana.

OBJECTIVE: To assess the needs of clients in a home-based care (HBC) program aimed at improving the quality of lives of people living with HIV in Region 4 of Guyana (Demerara-Mahaica region) following their involvement with the HBC program, volunteers, and nurse providers. DESIGN AND SAMPLE: A cross-sectional analysis of a needs assessment conducted through a verbally administered questionnaire. We collected a cross-sectional sample of 84 HBC clients living with HIV from Region 4 in Guyana. MEASURES: Respondents were administered a questionnaire that asked questions regarding the demographics; services received; quality of service delivery; and mental health and substance abuse. RESULTS: The services most commonly received by respondents included nutritional assessment and counseling, HIV prevention education, emotional support, hygiene education, support for antiretroviral adherence, and support for HIV disclosure. Respondents reported further need of referrals to income-generation opportunities, food and nutritional supplement support, and support for children. Forty-two percent of the respondents screened positive for probable depression, and 37% of respondents screened positive for being at risk for a drinking problem. CONCLUSIONS: While a substantial portion of needs were addressed by the HBC program, outstanding needs included linking people living with HIV to income-generation opportunities, food support, mental health, and services for children. We suggest that mental health and substance use services be factored into HIV programming and that referral systems be strengthened to ensure access to support services for people living with HIV.

Can teaching agenda-setting skills to physicians improve clinical interaction quality? A controlled intervention.

BACKGROUND: Physicians and medical educators have repeatedly acknowledged the inadequacy of communication skills training in the medical school curriculum and opportunities to improve these skills in practice. This study of a controlled intervention evaluates the effect of teaching practicing physicians the skill of "agenda-setting" on patients' experiences with care. The agenda-setting intervention aimed to engage clinicians in the practice of initiating patient encounters by eliciting the full set of concerns from the patient's perspective and using that information to prioritize and negotiate which clinical issues should most appropriately be dealt with and which (if any) should be deferred to a subsequent visit. METHODS: Ten physicians from a large physician organization in California with baseline patient survey scores below the statewide 25th percentile participated in the agenda-setting intervention. Eleven physicians matched on baseline scores, geography, specialty, and practice size were selected as controls. Changes in survey summary scores from pre- and post-intervention surveys were compared between the two groups. Multilevel regression models that accounted for the clustering of patients within physicians and controlled for respondent characteristics were used to examine the effect of the intervention on survey scale scores. RESULTS: There was statistically significant improvement in intervention physicians' ability to "explain things in a way that was easy to understand" (p = 0.02) and marginally significant improvement in the overall quality of physician-patient interactions (p = 0.08) compared to control group physicians. Changes in patients' experiences with organizational access, care coordination, and office staff interactions did not differ by experimental group. CONCLUSION: A simple and modest behavioral training for practicing physicians has potential to positively affect physician-patient relationship interaction quality. It will be important to evaluate the effect of more extensive trainings, including those that work with physicians on a broader set of communication techniques.

The Relationship Between Pregnancy Prevention and STI/HIV Prevention and Sexual Risk Behavior Among American Indian Men.

OBJECTIVE: We examined the relationship between American Indian men's attitudes toward pregnancy prevention, STI/HIV prevention, and sexual risk behavior. Attention was given to: (1) attitudes and intentions to use condoms and sexual risk behavior; (2) STI/HIV prevention characteristics and sexual risk behavior; (3) attitudes toward abstinence and monogamy and sexual risk behavior; and (4) decision-making in relationships and sexual risk behavior. STUDY DESIGN: Our sample included 120 heterosexual American Indian men aged 18 to 24 living on a reservation. Data were collected during in-depth interviews. A community-based participatory research framework was used to ensure the relevancy and acceptability of the study given the sensitivity of the topic. PRINCIPAL FINDINGS: Results demonstrated that attitudinal factors were associated with sexual risk behavior, particularly inconsistent condom use. Attitudes associated with consistent condom use suggested greater levels of positive dispositions toward prevention and intention to use condoms. Consistent condom use was associated with more cautious attitudes toward sex with multiple sex partners. Study results suggested that American Indian men who reported sex with multiple partners exhibited a set of attitudes and beliefs toward pregnancy prevention and STI/HIV prevention that corresponded with a disposition resulting from their behaviors, in that engaging in sexual risk behavior elevated their levels of risk perception. CONCLUSIONS: Our findings suggest that heterosexual American Indian men living in rural environments need sexual and reproductive health programs and clinical services that address differing attitudes toward condom use within the context of multiple sex partners and sexual risk behavior.

Perceived Level of Relationship Commitment, Sexual Risk Taking and Condom Use Among American Indian Men.

This study investigated commitment, sexual risk taking behavior and condom use among heterosexual men. The sample was 120 American Indian men ages 18-24 on the Fort Peck Reservation. Measures included sexual risk taking behaviors, attitude towards the relationship, discordance in perception of attitudes toward the relationship, and condom use. Inconsistent condom users comprised 57 % of the sample. Men with more than one sexual partner as well as men who reported inconsistent condom use reported less favorable attitudes toward their relationship. Discordant attitudes were observed in men who reported that their partner was more committed to the relationship then they were. This influenced having multiple sex partners. Inconsistent condom use decreased as respondents perceived an increasing level of partner's attachment to the relationship in comparison to themselves. Further examination of intimate partner relationship characteristics and how these dynamics influence sexual and reproductive health among American Indians is needed.

Time series analysis of sexual assault case characteristics and the 2007-2008 period of post-election violence in Kenya.

BACKGROUND: Following the declaration that President Mwai Kibaki was the winner of the Kenyan presidential election held on December 27, 2007, a period of post-election violence (PEV) took place. In this study, we aimed to identify whether the period of PEV in Kenya was associated with systematic changes in sexual assault case characteristics. METHODS AND FINDINGS: Medical records of 1,615 patients diagnosed with sexual assault between 2007 and 2011 at healthcare facilities in Eldoret (n = 569), Naivasha (n = 534), and Nakuru (n = 512) were retrospectively reviewed to examine characteristics of sexual assault cases over time. Time series and linear regression were used to examine temporal variation in case characteristics relative to the period of post-election violence in Kenya. Key informant interviews with healthcare workers at the sites were employed to triangulate findings. The time series of sexual assault case characteristics at these facilities were examined, with a specific focus on the December 2007-February 2008 period of post-election violence. Prais-Winsten estimates indicated that the three-month period of post-election violence was associated with a 22 percentage-point increase in cases where survivors did not know the perpetrator, a 20 percentage-point increase in cases with more than one perpetrator, and a 4 percentage-point increase in cases that had evidence of abdominal injury. The post-election violence period was also associated with an 18 percentage-point increase in survivors waiting >1 month to report to a healthcare facility. Sensitivity analyses confirmed that these characteristics were specific to the post-election violence time period. CONCLUSION: These results demonstrate systematic patterns in sexual assault characteristics during the PEV period in Kenya.

Condom use during last sexual contact and last 30 days in two samples of Caribbean military personnel.

Condom use during last sexual contact is a survey measure that may be used to inform monitoring and evaluation indicators of recent condom use in populations at risk for HIV infection and other sexually transmitted infections, such as the uniformed services. The authors tested for differences in condom use measures that were fielded within separate Biological and Behavioral Surveillance Surveys conducted in the armed forces of two separate nations: the Dominican Republic and Belize. Both surveys included measures of condom use during last sexual contact with specified partners and both surveys included the Risk Behavior Assessment (RBA), which measures specific sexual acts and condom use frequency during a specified time period. In both samples, more than 40% of respondents who reported condom use during last sexual contact with a regular partner also reported engaging in unprotected sex when screened with the RBA. Furthermore, more than 60% of respondents who reported condom use during last sexual encounter with a commercial sex worker also reported engaging in unprotected sex when screened with the RBA. The results carry implications for monitoring and evaluation indicators of large-scale HIV prevention programs. The authors recommend that, when feasible, more in-depth instruments such as the RBA be considered to measure recent condom use in populations of uniformed services personnel.

Correlates of sexual risk behavior in sexually active male military personnel stationed along border-crossing zones in the Dominican Republic.

CONTEXT: A survey was conducted of sexually active male military personnel stationed along major border-crossing zones between the Dominican Republic (DR) and Haiti, taking an applied scientific approach, to better inform prevention programming with military personnel in the region. DESIGN AND METHOD: A subsample of 470 sexually active male military personnel was drawn from a stratified systematic sample of military personnel stationed along the three largest border-crossing zones on the western border of the Dominican Republic. Using a verbally administered questionnaire, an examination of how foci of current HIV prevention programming with military personnel correlated with key sexual risk behavioral outcomes was conducted. RESULTS: Mental health factors such as probable alcohol abuse and posttraumatic stress disorder showed consistent associations with sexual risk behaviors. Participants showed a relatively high level of HIV/AIDS-related knowledge, a moderate level of negative attitudes toward condoms, and a moderate level of stigma toward people living with HIV/AIDS. Psychosocial factors, which are typically preventive in nature, were not associated with decreased sexual risk behaviors. CONCLUSION: Gaps were identified in HIV prevention programming that need to be addressed in this population of sexually active male military personnel. Although knowledge, attitudes, and psychosocial factors are important foci of HIV prevention programming, they were not associated with sexual risk behaviors, particularly after controlling for mental health factors. The authors suggest that prevalent psychiatric disorders in military personnel, such as posttraumatic stress disorder, should be factored in to the development of HIV prevention programs for military personnel.

Interviewer gender and self-reported sexual behavior and mental health among male military personnel.

OBJECTIVES: To determine whether self-reported sexual behavior and mental health varied by interviewer gender in a population of male military personnel. METHODS: Eight male and six female data collectors verbally administered structured interviews to 474 male Dominican military personnel stationed at border crossing zones in the Dominican Republic. Measurements included sexual behaviors and mental health. RESULTS: Respondents were less likely to report oral and vaginal sex to male interviewers, and were more likely to report sexual coercion and alcohol abuse to male interviewers. Respondents were more likely to report depression and post-traumatic stress disorder to female interviewers. CONCLUSION: Interviewer gender influenced the prevalence of sexual behaviors and mental health, which carries implications for future research in military personnel.

A randomized trial comparing mail versus in-office distribution of the CAHPS Clinician and Group Survey.

OBJECTIVE: To assess the effect of survey distribution protocol (mail versus handout) on data quality and measurement of patient care experiences. DATA SOURCES/STUDY SETTING: Multisite randomized trial of survey distribution protocols. Analytic sample included 2,477 patients of 15 clinicians at three practice sites in New York State. DATA COLLECTION/EXTRACTION METHODS: Mail and handout distribution modes were alternated weekly at each site for 6 weeks. PRINCIPAL FINDINGS: Handout protocols yielded an incomplete distribution rate (74 percent) and lower overall response rates (40 percent versus 58 percent) compared with mail. Handout distribution rates decreased over time and resulted in more favorable survey scores compared with mailed surveys. There were significant mode-physician interaction effects, indicating that data cannot simply be pooled and adjusted for mode. CONCLUSIONS: In-office survey distribution has the potential to bias measurement and comparison of physicians and sites on patient care experiences. Incomplete distribution rates observed in-office, together with between-office differences in distribution rates and declining rates over time suggest staff may be burdened by the process and selective in their choice of patients. Further testing with a larger physician and site sample is important to definitively establish the potential role for in-office distribution in obtaining reliable, valid assessment of patient care experiences.

Using mental health indicators to identify postdisaster gender-based violence among women displaced by Hurricane Katrina.

OBJECTIVE: Assessment of gender-based violence (GBV) among internally displaced persons (IDPs) is at best difficult. In complex humanitarian disasters, GBV inquiry can sometimes be dangerous and may lead to underestimation of the true prevalence. We developed a method of identifying women who have greater odds of having been exposed to postdisaster GBV (PDGBV) using mental health indicators. METHODS: We systematically random sampled IDPs living in travel trailer parks in Louisiana and Mississippi and interviewed respondents using a health needs assessment survey during an 8-week period in April and May 2006. Women (n = 194) were screened for GBV and symptoms of depression. RESULTS: Women were on average 43.3 years old (range 18-85). Of the nine symptoms assessed with the Patient Health Questionnaire-9 (PHQ-9), four were associated with PDGBV. Among women with sleep dysregulation, the odds of PDGBV were 2.5 times higher in comparison with women without sleep dysregulation (95% CI 1.2-5.1). Appetite dysregulation increased the odds by 3.8 (95% CI 1.4-10.3), low self-esteem increased the odds by 2.3 (95% CI 1.2-4.6), and suicidal ideation increased the odds by 2.7 (95% CI 1.1-6.7). The internal consistency reliability of this symptom cluster was higher among women with PDGBV. Women screening positive on all four symptoms were 2.7 times more likely to have experienced PDGBV (95% CI 1.03-7.1). CONCLUSIONS: Several but not all symptoms of depression indicated exposure to PDGBV. Sleeping dysregulation, appetite dysregulation, low self-esteem, and suicidal ideation should be considered secondary indicators useful for identifying the prevalence of PDGBV exposure among female IDPs. This model may be useful for identifying women with exposure to PDGBV in settings where direct questioning may not be safe and reliable.

Access to care among displaced Mississippi residents in FEMA travel trailer parks two years after Katrina.

The health care needs of Gulf Coast residents displaced by Hurricane Katrina in 2005 who remain in travel trailer parks nearly three years later have not been evaluated. We conducted a population-based assessment of the health care access of residents of these travel trailer parks in Mississippi. Our findings indicate a worsening of chronic disease, mental illness, and barriers to health care access since displacement. Meeting both the chronic disease and the mental health needs of people displaced by the hurricanes of 2005 is essential for ensuring their full recovery and that of the region.

Sexual risk behavior among military personnel stationed at border-crossing zones in the Dominican Republic / Comportamiento sexual riesgoso del personal militar en zonas de paso fronterizo de la República Dominicana

OBJETIVO. Calcular la prevalencia del comportamiento sexual riesgoso del personal militar que sirve en las principales zonas de paso fronterizo entre la República Dominicana y Haití. MÉTODOS. De noviembre del 2008 a enero del 2009, se aplicaron encuestas sobre comportamiento a 498 miembros del personal militar que estaba en servicio activo en las tres zonas principales de paso fronterizo de la frontera occidental de la República Dominicana. Se seleccionó una muestra aleatoria y sistemática de participantes, a los que se les formularon preguntas sobre su comportamiento sexual de los últimos 12 meses, el consumo de bebidas alcohólicas y la salud mental. RESULTADOS: De todos los entrevistados, 41 por ciento revelaron que habían mantenido relaciones sexuales casuales en los últimos 12 meses, 37 por ciento de los hombres alguna vez habían mantenido relaciones sexuales con un profesional del sexo (19 por ciento en los últimos 12 meses) y 7 por ciento de los hombres informaron que habían tenido relaciones sexuales con personas de Haití que cruzaron la frontera (6 por ciento en los últimos 12 meses). De los entrevistados no monógamos (51 por ciento), más de 60 por ciento de los que mantuvieran relaciones por vía anal, vaginal u oral no fueron constantes en el uso de preservativos. Refirieron el uso de coacción sexual en los últimos 12 meses 15 por ciento de los entrevistados. CONCLUSIONES: †El comportamiento sexual riesgoso es prevalente entre los miembros del personal militar que sirve en las zonas de paso fronterizo entre República Dominicana y Haití. Los programas de prevención contra la transmisión del VIH destinados al personal militar de esta región deben incorporar como temas esenciales la coacción sexual y la salud mental.
