Background: The ARMADILLO Study determined whether adolescents able to access SRH information on-demand via SMS were better able to reject contraception-related myths and misconceptions as compared with adolescents receiving pushed SMS or no intervention. Trial design: This trial was an unblinded, three-arm, parallel-group, individual RCT with a 1:1:1 allocation. Trial registration: ISRCTN85156148. Methods: This study was conducted in Lima, Peru among participants ages 13–17 years. Eligible participants were randomized into one of three arms: Arm 1: access to ARMADILLO's SMS information on-demand; Arm 2 access to ARMADILLO SMS information pushed to their phone; Arm 3 control (no SMS). The intervention period lasted seven weeks. At baseline, endline, and follow-up (eight weeks following endline), participants were assessed on a variety of contraception-related myths and misconceptions. An index of myths-believed was generated. The primary outcome assessed the subject-specific change in the mean score between baseline and endline. Knowledge retention from endline to follow-up was also assessed, as was a 'content exposure' outcome, which assessed change in participants' knowledge based on relevant SMS received. Results: In total, 712 participants were randomized to the three arms: 659 completed an endline assessment and were included in the primary analysis. Arm 2 participants believed fewer myths at endline compared with control arm participants (estimated subject-specific mean difference of -3.69% [-6.17%, -1.21%], p = 0.004). There was no significant difference between participants in Arm 1 vs. the control Arm, or between participants in Arm 1 vs. Arm 2. A further decrease in myths believed between endline and follow-up (knowledge retention) was observed in all arms; however, there was no difference between arms. The content exposure analysis saw significant reductions in myths believed for Arm 1 (estimated subject-specific mean difference of -9.47% [-14.83%, -4.11%], p =.001) and Arm 2 (-5.93% [-8.57%, -3.29%], p <.001) as compared with the control arm; however Arm 1's reduced sample size (n = 28) is a severe limitation. Discussion: The ARMADILLO SMS content has a significant (but small) effect on participants' contraception-related knowledge. Standalone, adolescent SRH digital health interventions may affect only modest change. Instead, digital is probably best used a complementary channel to expand the reach of existing validated SRH information and service programs. [ABSTRACT FROM AUTHOR]

Background: Adolescents may forego needed sexual and reproductive health (SRH) services due to a variety of concerns and barriers. The purpose of this study is to compare adolescents' perceptions of these barriers by participant characteristics including race/ethnicity, gender, sexual orientation, housing situation, and sexual experience.Methods: Adolescents in a California-wide sexual health education program completed an anonymous survey at baseline (N = 10,015) about perceived barriers to using SRH services. Logistic regression analyses that accounted for the clustered data structure assessed differences by gender, age, sexual orientation, race/ethnicity, living situation, and sexual experience.Results: The majority of participants were Hispanic/Latino (76.4%) with an average age of 14.9 years, and 28.8% had sexual experience. Half of the youth reported concerns about test results (52.7%), cost of services (52.0%), and confidentiality of services (49.8%). When controlling for other characteristics, youth identifying as transgender/non-binary/multiple genders had the highest odds of perceiving cost (odds ratio (OR) 1.89) and confidentiality (OR 1.51) as barriers. Increasing age was associated with decreasing odds of all barriers. Sexual orientation was a consistent predictor, with LGBQ+ youth having higher odds of perceiving test results (OR 1.21), cost (OR 1.36), and confidentiality (OR 1.24) as barriers. Asian or Pacific Islander/Native Hawaiian youth had higher odds of perceiving test results (OR 1.68) and cost (OR 1.37) as barriers. In contrast, Black youth had lower odds of reporting cost (OR 0.65) and confidentiality (OR 0.77) as barriers. Younger respondents and youth who identified as female, transgender/non-binary/multiple genders, LGBQ+, and Asian or Pacific Islander/Native Hawaiian had higher odds of reporting five or more barriers compared to reference groups.Conclusions: The majority of adolescents face barriers to accessing appropriate SRH services, with females, gender-minority youth, younger adolescents, LGBQ+ youth, and Asian and Pacific Islander/Native Hawaiian youth more likely than others to report barriers. Access to SRH services can be improved through strengthening linkages between clinics and SRH education programs, providing youth-friendly clinical services, and ensuring youth have sufficient information, skills, and support to access care.Trial Registration: Approved by California Health and Human Services Agency's Committee for the Protection of Human Subjects [12-08-0658, 11/30/2017].

Mother-to-child transmission of HIV (MTCT) accounts for a significant proportion of new HIV infections in Peru. The purpose of this case-control study was to examine maternal and infant factors associated with MTCT in Peru from 2015 to 2016. For each biologically confirmed case infant, we randomly selected four birth year- and birth hospital-matched controls from five hospitals in Lima-Callao. Maternal and infant information were gathered from medical records. Simple conditional logistic regression was utilized to examine possible maternal and infant characteristics associated with MTCT. The rate of MTCT was 6.9% in 2015 and 2.7% in 2016. A total of 63 matched controls were identified for 18 cases. Protective factors included higher number of prenatal visits (odds ratio [OR]: 0.72; 95% confidence interval [CI]: 0.55-0.94, p = 0.012) and having more children (OR: 0.10, 95% CI: 0.01-0.79, p = 0.029). Risk factors included later maternal diagnosis (OR: 1.19; 95% CI: 1.06-1.34; p = 0.001) and greater viral load at the time of maternal diagnosis (OR: 1.05; 95% CI: 1.01-1.10; p = 0.022). Our study highlights the importance of targeting early and continued prenatal care as specific areas to target to prevent gaps in the HIV treatment cascade for pregnant HIV-infected women. These strategies can ensure early screening and initiation of antiretroviral therapy to reduce MTCT rates. [ABSTRACT FROM AUTHOR]

Background: Improved access to sexual and reproductive health (SRH) services and information is essential for supporting adolescents and youth in making informed decisions and optimizing each young person's outcomes related to their SRH, health and well-being and countries' current and future social and economic development. Mobile phones offer opportunities for young people to privately access SRH content and to be linked to SRH services. The objective of this study was to develop the content for an SMS (short message service or "text message") platform jointly with adolescents and youth in three regions in Peru (Lima, Ayacucho and Loreto) as part of the ARMADILLO (Adolescent/Youth Reproductive Mobile Access and Delivery Initiative for Love and Life Outcomes) Study. Methods: Content development was done in three stages. During Stage 1, we held community consultations with 13–17 year old adolescents, 18–24 year old youth and professionals who work with young people through the education and health sectors ("adult advisers") to identify and rate SRH topics of interest through group free- and guided-brainstorming activities and an individual written sharing activity. During Stage 2, the team developed the preliminary domains, sub-domains and content for the SMS platform. During Stage 3, we held focus groups with adolescents to validate the SMS content, including both individual scoring of and group feedback for each SMS. Group feedback asked about their general impressions and understanding and their thoughts about the language and usefulness of the SMS. Results: A total of 172 adolescents and youth ages 13–24 and 20 adult advisers participated. Adolescents and youth brainstormed and rated SRH topics and sub-topics that led to the initial structure for the SMS platform, with 9 domains, 25 sub-domains and 146 draft SMS. Adolescents provided high scores for the SMS, with all sub-domains receiving average scores of 3.0 or higher (out of 4.0) for the SMS included. Adolescents also provided suggestions to optimize content, including improvements to unclear messages, resulting in SMS with adolescent-friendly content in simple, straightforward language. This process also revealed that adolescents lacked knowledge and had misconceptions related to contraceptive methods. Conclusion: This study details the systematic process used to develop relevant and accessible SRH information through a participatory approach. We document critical information about what young people know and how they think, enabling us to understand their perspective and literally speak their language. Results also provide future directions for programmatic, research and policy efforts with young people, in particular around gender norms, interpersonal violence, and access to SRH information and services, in similar settings.

HIV disproportionately affects men who have sex with men and transwomen in Latin America. Globally, efforts to map, enumerate, and describe male and transwomen sex workers (MTSWs) are limited. We mapped and described venue- and non-venue–based MTSWs and enumerated venuebased MTSWs in Lima, Peru's capital. With venue-based MTSWs, we identified and described the venues, SWs, and clients and enumerated the SWs. With non-venue–based MTSWs, we described SW offerings and SWs. Male SWs (MSWs) are concentrated downtown, with many moving online. Transwomen SWs (TSWs) are spread across metropolitan Lima, with fewer online. At venues, there are more TSWs than MSWs, TSWs reported more HIV and sexual risk behaviors, and MSWs had more female partners. Non-venue–based MSWs used condoms less than venue-based MSWs. Results support systematic efforts to describe hard-to-reach MTSWs and their different types of partners, all of whom have unique, differing needs for HIV/ STI education, prevention, testing, and care services.

Peruvian children's sub-optimal results on international and national assessments underscore the need for enhanced investments in early childhood development (ECD) such as shared reading between caregivers and young children. We conducted a qualitative study with 13 mothers of young children ages 11–25 months old that: used focus groups to explore caregivers' perspectives and experiences related to their daily activities, including reading and other ECD activities, with their young children; and used focus groups and video recordings to describe caregivers' experiences reading with these children during an at-home opportunity for shared reading. The mothers described daily schedules that focused on taking care of their daily chores and making sure that their young children were busy as they carried out those tasks. The mothers reported that they did not designate dedicated time to spend with their children, and children were often without adult attention for lengthy periods of time. We found that after the 1-month at-home opportunity for shared reading, there was a definite positive shift in both mothers' engagement with their children and their perspectives on reading. The caregivers improved their daily interactions with their children and observed important changes in their children thanks to reading. This study is encouraging and justifies a follow up randomized controlled trial to implement and evaluate the LIBRE shared reading program in Lima, Peru. [ABSTRACT FROM AUTHOR]

To solve increasingly complex global health problems, health professionals must collaborate with professionals in non-health-related fields. The Universidad Peruana Cayetano Heredia and University of Washington created the NIH-funded Kuskaya training program in response to the need for transformative global health training for talented graduates from all disciplines. Kuskaya is a 1-year, interdisciplinary training program that teaches Peruvian and US graduates critical skills related to public health research through the design and implementation of a collaborative research project in Peru. Between 2014 and 2018, the program has trained 33 fellows, of which one third were from non-health disciplines. The program is unique because it targets junior trainees from disciplines outside of the health field, the program's curriculum is adapted to fit the fellows' backgrounds and professional aspirations, and the structure of the program allows for collaboration within the cohort and encourages fellows to apply for additional funding and pursue advanced degrees. Lessons learned in designing the Kuskaya program include: 1) involving mentors in the fellow selection process, 2) involving fellows in existing lines of research to increase mentor involvement, 3) institutionalizing mentoring through regular works-in-progress meetings and providing mentoring materials, and 4) defining a core curriculum for all fellows while providing additional supplementary materials to meet each cohort's needs, and evaluating their progress. Kuskaya provides an innovative model for bi-national, global health training to engage and provide a public health career pathway for all professionals. [ABSTRACT FROM AUTHOR]

Introduction: Although the worldwide incidence of tuberculosis (TB) is slowly decreasing, annual infection rates in Peru remain among the highest in the Americas. Pharmacies could play an important role in facilitating early detection of TB. However, the awareness, expertise and cooperation of pharmacy workers is fundamental. This study explored the TB-related knowledge, attitudes and practices of pharmacy workers in a district with one of the highest incidences of TB in Peru. Methods: This cross-sectional study applied a questionnaire that was administered face to face using smartphones with one pharmacy worker at each of 45 randomly selected pharmacies in the El Agustino district of Lima, Peru. Results: Participants were primarily female (78%) and had an average age of 31.3 years old (range 18–57 years old). Only 11% of participants were pharmacists with complete university training. The pharmacy workers’ knowledge was adequate; however, workers had important knowledge gaps and myths regarding prevention of TB transmission. Most pharmacy workers (77%) reported they would send a client with a history of cough for more than two weeks to a healthcare center, while 23% reported they would offer them antitussive medication or antibiotics. Almost all workers reported talking with clients about diseases and reported respiratory symptoms as one of the most common causes for consultation (60%). Most participants expressed interest in learning more about TB and expanding their involvement in the fight against TB in their community. Conclusion: Pharmacy workers have adequate knowledge about TB. However, we identified gaps in knowledge with respect to prevention of TB transmission. Pharmacy workers commonly see patients with respiratory symptoms and some offer recommendations, including for treatment. Pharmacy workers are willing to learn more and contribute to TB control and could be a valuable asset in the control and prevention of TB in Peru. To achieve this integration of pharmacy workers into TB control and prevention, more research is needed. [ABSTRACT FROM AUTHOR]

Purpose: Mental disorders are a major contributor to the global burden of disease and disability, and can be extremely costly at both individual and community level. Social capital, (SC) defined as an individual's social relationships and participation in community networks, may lower the risk of mental disorders while increasing resilience capacity, adaptation and recovery. SC interventions may be a cost-effective way of preventing and ameliorating these conditions. However, the impact of these SC interventions on mental health still needs research.Methods: We conducted a systematic review of SC-based interventions to investigate their effect on mental health outcomes from controlled, quasi-experimental studies or pilot trials. We searched twelve academic databases, three clinical trials registries, hand-searched references and contacted field experts. Studies' quality was assessed with the Cochrane Risk of Bias tools for randomized and non-randomized studies.Results: Seven studies were included in the review, published between 2006 and 2016. There was substantial heterogeneity in the definitions of both SC and mental disorders among the studies, preventing us from calculating pooled effect sizes. The interventions included community engagement and educative programs, cognitive processing therapy and sociotherapy for trauma survivors, and neighbourhood projects.Conclusions: There are paucity of SC interventions investigating the effect on mental health outcomes. This study showed that both SC scores and mental health outcomes improved over time but there was little evidence of benefit compared to control groups in the long term. Further high-quality trials are needed, especially among adverse populations to assess sustainability of effect. [ABSTRACT FROM AUTHOR]

Objectives: To determine the socio-demographics, sexual practices, and HIV prevalence of male sex workers (MSWs), transwomen sex workers (TSWs), and their male clients in Lima, Peru. Methods: Following ethnographic mapping of sex work venues, the authors revisited randomly selected venues to survey MSWs, TSWs and their clients. Results: MSWs and TSW clients are more educated than MSW clients and TSWs. Only 50% of TSW clients have received HIV testing. Self-reported HIV positivity is highest among MSW clients and TSWs. Conclusion: Notable differences exist between MSWs and TSWs and their clients that can affect the health of these groups and warrant intervention. [ABSTRACT FROM AUTHOR]

Background: The parasitic disease, cystic echinococcosis (CE), is prevalent in low-income, livestock-raising communities and 2000 new people will be diagnosed this year in South America alone. The disease usually passes from livestock to dogs to humans, making it a zoonotic disease and part of the One Health Initiative. Control of CE has been infamously difficult; no endemic areas of South America have succeeded in maintaining sustainable eradication of the parasite. For the current study, we aimed to gain a better understanding of the knowledge, attitudes, and practices of rural sheep farmers and other community leaders regarding their sheep herding practices and perspectives about a control program for CE. We also hope to identify potential barriers and opportunities that could occur in a control program. The authors conducted Knowledge, Attitude and Practices (KAP) surveys and semi-structured interviews in rural communities in the highlands of Peru. The KAP surveys were administered to 51 local shepherds, and the semi-structured interviews were administered to 40 individuals, including shepherds, community leaders, and health care providers. Results: We found that the shepherds already deworm their sheep at a median of 2 times per year ( =49, range 2-4) and have a mean willingness-to-pay of U.S. $ 0.60 for dog dewormer medication ( = 20, range = 0.00- $2.00 USD). We were not able to learn the deworming agent or agents that were being used, for neither sheep nor dogs. Additionally, 90% of shepherds slaughter their own sheep ( = 49). We also learned that the main barriers to an effective control program include: lack of education about the cause and control options for CE, accessibility to the distant communities and sparse grazing pastures, and a lack of economic incentive. Conclusions: Findings suggest it may be feasible to develop an effective CE control program which can be used to create an improved protocol to control CE in the region. [ABSTRACT FROM AUTHOR]

In Peru, a significant proportion of people tested for HIV and syphilis do not receive timely results. Our objective was to assess the institutional feasibility of implementing simultaneous HIV/syphilis point-of-care tests and client perceptions regarding these point-of-care tests. Point-of-care tests were implemented in a hospital consultation room in a marginalised zone of Lima. A time-series design was used to compare the proportion of tested clients who received timely results, with and without the point-of-care test intervention. Experience and satisfaction with point-of-care tests was evaluated with 149 people. In the 6 months without intervention, 69% and 61% of clients tested for HIV and syphilis, respectively, received their results within the required 45-minute window. During the 2-month point-of-care test intervention, all clients tested for HIV (n = 387) and syphilis (n = 398) received their results within 45 minutes. All clients surveyed were completely satisfied (52%) or satisfied (48%) with the simultaneous HIV/syphilis point-of-care test screening process. Additionally, 73% strongly agreed with the statement ‘I feel satisfied with the rapid testing process.’ Screening using point-of-care tests represents an important opportunity to reduce the time, resource and cost burden for users and institutions and increase the proportion of users receiving their test results in a timely manner.

In Peru, there are few studies on male sex workers (MSWs), and existing studies explore limited subgroups or offer limited information about MSWs’ perspectives. This study provides in-depth perspectives from 40 MSWs who work in downtown Lima (Cercado) and in surrounding urban neighborhoods (non-Cercado) through interviews on their identities, lives, and HIV/STI (sexually transmitted infection) risks and vulnerabilities. Findings are that entry into sex work links economy and affection, particularly among Cercado MSWs. Continued sex work cements this link, making it difficult to exit sex work and establish goals. Ties between economics and affections influence MSWs’ perceived HIV/STI risks, vulnerabilities, and prevention practices. Although Cercado MSWs report higher HIV/STI risks and vulnerabilities than non-Cercado peers, they report fewer prevention practices given inability to buy condoms and acceptance of client offers of higher payment, especially clients they feel affection for. MSWs need support to strengthen their self-perceptions and define and pursue their goals in order to improve their HIV/STI prevention practices, health, and well-being. [ABSTRACT FROM PUBLISHER]

Peru’s approach to its 5.7 million 10- to 19-year-olds has shifted toward positive youth development. Following that trend, our objective was to facilitate Peruvian adolescents’ use of photovoice to better understand the factors affecting their health, well-being, and sexuality and to work with adolescents to present policy and programmatic recommendations. Photovoice sessions were carried out with low-income 12- to 16-year-olds (n = 13) from Lima. Sessions included basic photography and ethics, photo taking, and descriptions and discussions using the SHOWeD (What do you See here? What is really Happening? How does this relate to Our lives? Why does this problem or strength exist? What can we Do about it?) method. Participants grouped their photos into a “photo story.” Each section of the story consisted of a message and 4 to 10 photos. Each photo had a caption that answered the SHOWeD questions. Messages were (a) “health and well-being in danger of extinction,” (b) “with some signs of hope,” (c) “innocence in spite of everything,” (d) “what we as adolescents have,” and (e) “but we lack opportunities to live a better life and a responsible sexuality.” Participants presented the photo story to program planners, policy makers, and community members. Results underscore the value of including adolescents in program and policy planning and affirm that photovoice can achieve such inclusion. Photovoice provides a concrete method for adolescents to speak their mind through image and word. [ABSTRACT FROM PUBLISHER]

Objectives To describe the sociodemographic and sex work characteristics, recent sexual practices, HIV risk perception and testing history, and HIV and syphilis prevalence of Cercado (downtown) and non-Cercado (close urban) male sex workers (MSWs) in Lima, Peru. Methods Eighty-nine MSWs completed a self-administered survey and participated in HIV and syphilis testing. Results Cercado MSWs had significantly lower median weekly earnings than non-Cercado MSWs (US$43 vs US $72, p=0.04). Most non-Cercado MSWs (81%) reported only insertive anal intercourse with male/transgender partners, while Cercado MSWs primarily reported only insertive (52%) or insertive and receptive (45%) anal intercourse ( p=0.03). Consistent condom use was low with insertive and receptive anal intercourse in both subgroups. Among MSWs with recent female partners, condom use with the last partner was lower among Cercado versus non-Cercado MSWs for vaginal sex (37% vs 65%, p=0.04) and anal sex (27% vs 80%, p=0.01). More Cercado than non-Cercado MSWs (57% vs 42%) perceived high HIV risk (p=0.05) and Cercado MSWs had a much higher prevalence than non-Cercado MSWs of HIV (23% vs 4%, p=0.04) and syphilis (22% vs 0%, p=0.02) infections. Conclusions MSWs in Lima are diverse and Cercado MSWs are 'just getting by,' engaging in more risk behaviours, and more likely to have HIV/STIs. Future research should identify, describe and carry out HIV/STI testing with broader groups of MSWs and their client and non-client partners. Prevention efforts should provide HIV/STI risk reduction education for MSWs and related subgroups who are currently not targeted such as female partners. [ABSTRACT FROM AUTHOR]

During the 1997-98 El Niño, Tumbes, Peru received 16 times the annual average rainfall. This study explores how Tumbes residents perceived the impact of the El Niño event on basic necessities, transport, health care, jobs and migration. Forty-five individuals from five rural communities, some of which were isolated from the rest of Tumbes during the event, participated in five focus groups; six of these individuals constructed nutrition diaries. When asked about events in the past 20 years, participants identified the 1997-98 El Niño as a major negative event. The El Niño disaster situation induced a decrease in access to transport and health care and the rise in infectious diseases was swiftly contained. Residents needed more time to rebuild housing; recover agriculture, livestock and income stability; and return to eating sufficient animal protein. Although large-scale assistance minimized effects of the disaster, residents needed more support. Residents' perspectives on their risk of flooding should be considered in generating effective assistance policies and programmes. [ABSTRACT FROM AUTHOR]

Background Globally, no qualitative studies have explored the perspectives of women and their partners about the integration of technology - and specifically diagnostic testing technologies - into antenatal care. The study objective was to describe the demand side for pregnancy-related diagnostic tests from the perspective of Peruvian consumers, including female and male community members, by engaging participants about their awareness of and care-seeking for pregnancy-related diagnostic tests and their preferred characteristics and testing conditions for pregnancy-related point-of-care diagnostic tests (POCTs). Methods Sixty-seven mothers and fathers of children under one from the peri-urban coast and the periurban and rural highlands and jungle of Peru participated in ten focus groups. Results Participants think that pregnancy-related diagnostic tests are important and they and their fellow community members are committed to ensuring that pregnant women receive the tests they need. Participants expressed clear demands for pregnancy-related POCTs, including important characteristics for the tests themselves (certification, rapid, reliable results) and for test implementation (well-trained, personable good communicators as test administrators at well-equipped, convenient testing sites). Participants emphasized the importance of short waiting times and explained that many people have some ability to pay for POCTs, particularly if they are innovative, rapid or multiplex. Conclusions Engaging future POCT Engaging future POCT users as consumers who are able to make key decisions about the development and implementation of pregnancy-related POCTs is valuable and informative.

Abstract: This study explores the lives of Peruvian adolescents in a low-income human settlement outside of Lima. Twenty 12–17 year olds were asked to narrate their own life stories using the life history narrative research method. Holistic content analysis was coupled with a grounded-theory approach to explore these data. Intergenerational responsibility, family tensions, economic pressures, racism and violence emerged without prompting and dominated the narrators'' life stories, underscoring the degree to which these adolescents lack access to the supportive individuals and structures that are key to positive adolescent development. The challenges faced by these and the other 5.8 million 10–19 year olds in Peru require increased attention to the role of families, peers and communities in ensuring that adolescents are able to maintain their well-being and achieve their future expectations.

There are between 8 and 11 million cases of America Human Trypanosomiasis, commonly known as Chagas disease, in Latin America. Chagas is endemic in southern Peru, especially the Arequipa region, where it has expanded from poor, rural areas to periurban communities. This paper summarizes the findings of four studies in periurban Arequipa: on determinants of disease-vector infestation; on prevalence, spatial patterns, and risk factors of Chagas; on links between migration, settlement patterns, and disease-vector infestation; and on the relationship between discordant test results and spatially clustered transmission hotspots. These studies identified two risk factors associated with the disease: population dynamics and the urbanization of poverty. Understanding the disease within this new urban context will allow for improved public health prevention efforts and policy initiatives. Discovered in 1909 by Brazilian physician Carlos Chagas, American Human Trypanosomiasis is a chronic and potentially life-threatening illness found throughout Latin America (Moncayo, 2003). Indeed, it is estimated that there are between 8 and 11 million cases in Mexico and Central and South America (Centers for Disease Control [CDC], 2009). Chagas disease, as it is most commonly known, is endemic in southern Peru, especially in the region of Arequipa. Once thought to be limited to poor, rural areas, the disease is now appearing in the periurban communities that surround Arequipa City, the capital of the region (Cornejo del Carpio, 2003). Understanding the urbanization of Chagas disease will allow public health and medical professionals to better combat the further transmission of the disease. After providing an overview of Chagas and introducing the scope of the disease in Latin America, this paper will summarize the findings of four recent studies conducted in periurban districts in Arequipa. Ultimately, this paper seeks to identify the risk factors associated with Chagas infection in Arequipa's periurban communities. [ABSTRACT FROM AUTHOR]

Background: There is evidence that female gender is associated with reduced likelihood of tuberculosis diagnosis and successful treatment. This study aimed to characterize gender-related barriers to tuberculosis control in Peruvian shantytowns.Methods: We investigated attitudes and experiences relating gender to tuberculosis using the grounded theory approach to describe beliefs amongst key tuberculosis control stakeholders. These issues were explored in 22 semi-structured interviews and in four focus group discussions with 26 tuberculosis patients and 17 healthcare workers.Results: We found that the tuberculosis program was perceived not to be gender discriminatory and provided equal tuberculosis diagnostic and treatment care to men and women. This contrasted with stereotypical gender roles in the broader community context and a commonly expressed belief amongst patients and healthcare workers that female health inherently has a lower priority than male health. This belief was principally associated with men's predominant role in the household economy and limited employment for women in this setting. Women were also generally reported to experience the adverse psychosocial and economic consequences of tuberculosis diagnosis more than men.Conclusions: There was a common perception that women's tuberculosis care was of secondary importance to that of men. This reflected societal gender values and occurred despite apparent gender equality in care provision. The greatest opportunities for improving women's access to tuberculosis care appear to be in improving social, political and economic structures, more than tuberculosis program modification.

Background: Chagas disease is one of the most important neglected tropical diseases in the Americas. Vectorborne transmission of Chagas disease has been historically rare in urban settings. However, in marginal communities near the city of Arequipa, Peru, urban transmission cycles have become established. We examined the history of migration and settlement patterns in these communities, and their connections to Chagas disease transmission. Methodology/Principal Findings: This was a qualitative study that employed focus group discussions and in-depth interviews. Five focus groups and 50 in-depth interviews were carried out with 94 community members from three shantytowns and two traditional towns near Arequipa, Peru. Focus groups utilized participatory methodologies to explore the community's mobility patterns and the historical and current presence of triatomine vectors. In-depth interviews based on event history calendars explored participants' migration patterns and experience with Chagas disease and vectors. Focus group data were analyzed using participatory analysis methodologies, and interview data were coded and analyzed using a grounded theory approach. Entomologic data were provided by an ongoing vector control campaign. We found that migrants to shantytowns in Arequipa were unlikely to have brought triatomines to the city upon arrival. Frequent seasonal moves, however, took shantytown residents to valleys surrounding Arequipa where vectors are prevalent. In addition, the pattern of settlement of shantytowns and the practice of raising domestic animals by residents creates a favorable environment for vector proliferation and dispersal. Finally, we uncovered a phenomenon of population loss and replacement by low-income migrants in one traditional town, which created the human settlement pattern of a new shantytown within this traditional community. Conclusions/Significance: The pattern of human migration is therefore an important underlying determinant of Chagas disease risk in and around Arequipa. Frequent seasonal migration by residents of peri-urban shantytowns provides a path of entry of vectors into these communities. Changing demographic dynamics of traditional towns are also leading to favorable conditions for Chagas disease transmission. Control programs must include surveillance for infestation in communities assumed to be free of vectors. Author Summary: Chagas disease affects 8–10 million people in the Americas. Although transmission was previously limited to the rural poor, Chagas increasingly affects urban populations, especially near the city of Arequipa, Peru. We interviewed residents of five communities to learn about why and when they migrated to the city and how their movements may link to Chagas vectors and to explore the settlement patterns of shantytowns and traditional towns. We found that migrants to shantytowns were unlikely to introduce Chagas vectors to the city upon first arrival. Frequent seasonal moves, however, took shantytown residents to valleys surrounding Arequipa where vectors are prevalent. In addition, the settlement pattern of shantytowns and the practice of raising domestic animals create a favorable environment for vectors. Finally, population loss and replacement by low-income migrants in one traditional town has created the human settlement pattern of a shantytown. This study exposes potential links between population dynamics and Chagas vector infestation. Suggested methods for improving vector control include focusing future vector surveillance in areas with mobile populations, creating educational campaigns for migrant workers to Chagas-endemic areas, and fomenting collaboration between the Arequipa Ministries of Health and Housing to ensure the inclusion of new shantytowns in vector surveillance.

We examined the history of migration and settlement patterns in these communities, and their connections to Chagas disease transmission. Methodology/Principal Findings: This was a qualitative study that employed focus group discussions and in-depth interviews. Five focus groups and 50 in-depth interviews were carried out with 94 community members from three shantytowns and two traditional towns near Arequipa, Peru. Focus groups utilized participatory methodologies to explore the community's mobility patterns and the historical and current presence of triatomine vectors. In-depth interviews based on event history calendars explored participants' migration patterns and experience with Chagas disease and vectors. Focus group data were analyzed using participatory analysis methodologies, and interview data were coded and analyzed using a grounded theory approach. Entomologic data were provided by an ongoing vector control campaign. We found that migrants to shantytowns in Arequipa were unlikely to have brought triatomines to the city upon arrival. Frequent seasonal moves, however, took shantytown residents to valleys surrounding Arequipa where vectors are prevalent. In addition, the pattern of settlement of shantytowns and the practice of raising domestic animals by residents creates a favorable environment for vector proliferation and dispersal. Finally, we uncovered a phenomenon of population loss and replacement by low-income migrants in one traditional town, which created the human settlement pattern of a new shantytown within this traditional community. Conclusions/Significance: The pattern of human migration is therefore an important underlying determinant of Chagas disease risk in and around Arequipa. Frequent seasonal migration by residents of peri-urban shantytowns provides a path of entry of vectors into these communities. Changing demographic dynamics of traditional towns are also leading to favorable conditions for Chagas disease transmission. Control programs must include surveillance for infestation in communities assumed to be free of vectors. [ABSTRACT FROM AUTHOR]
