Objective: To evaluate the association between breastfeeding duration and educational outcomes at the end of secondary education among children from the Millennium Cohort Study., Design: Cohort study comparing school results at age 16 according to breastfeeding duration., Setting: England., Participants: Children born in 2000-2002 (nationally representative sample)., Exposure: Self-reported breastfeeding duration (categorised)., Main Outcome Measures: Standardised school assessments taken at the end of secondary education (General Certificate of Secondary Education (GCSEs), marked 9-1) in English and Mathematics, categorised as: 'fail, marks <4', 'low pass, marks 4-6' and 'high pass, marks ≥7 (equivalent to A-A*)'. Additionally, overall achievement was measured using the 'attainment 8' score (adding the marks of eight GCSEs, English and Mathematics double weighted; 0-90)., Results: Approximately 5000 children were included. Longer breastfeeding was associated with better educational outcomes. For example, after full adjustment for socioeconomic markers and maternal cognitive ability, in comparison with children who were never breastfed, those who were breastfed for longer were more likely to have a high pass in their English and Mathematics GCSEs, and less likely to fail the English GCSE (but not the Mathematics GCSE). Additionally, compared with those never breastfed, those breastfed for at least 4 months had, on average, a 2-3 point higher attainment 8 score (coefficients: 2.10, 95% CI 0.06 to 4.14 at 4-6 months; 2.56, 95% CI 0.65 to 4.47 at 6-12 months and 3.09, 95% CI 0.84 to 5.35 at ≥12 months)., Conclusions: A longer breastfeeding duration was associated with modest improvements in educational outcomes at age 16, after controlling for important confounders., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Aim: To evaluate disparities in the frequency of scientific activity between medical doctors and nurses in Peru., Methods: We carried out a secondary data analysis of the National Health Services Users' Satisfaction Survey (ENSUSALUD), 2016. This nationally representative survey evaluates doctors and nurses working in clinical settings. We defined scientific activity as i) having published an original article (journal indexed in Web of Science, Scopus or Medline); and ii) having authored an abstract in a national or international conference. We estimated crude and adjusted disparities prevalence ratios (aDPR) and 95% confidence intervals (95%CI)., Results: We included 2025 doctors and 2877 nurses in the analysis; 71% of doctors doctor were male, and 93% of nurses were female (p<0.001). Among doctors, 13.9% had published an article, and 8.4% presented an abstract at a conference in the last two years, while these proportions were 0.6% and 2.5% for nurses, respectively. The adjusted models showed that doctors, when compared to nurses, were approximately 27 times likely to have published a paper (aDPR = 27.86; 95% CI 10.46 to 74.19) and twice as likely to have authored a conference abstract (aDPR = 2.51; 95% CI 1.39 to 4.53)., Conclusions: There are important disparities in scientific activity between doctors and nurses working in clinical settings in Peru. Disparities are more significant for article publication than for authoring in conference abstracts. We suggest public policies that promote research dissemination between health professionals, with emphasis on nurses., Competing Interests: The authors have declared that no competing interests exist.

Introduction: Approximately, one in three Peruvian children aged 6 to 59 months old have anaemia. Maternal depression, which may be disabling and affect the proper care of children, is associated with chronic malnutrition in their offspring. Therefore, the aim of this study is to evaluate if there is an association between depressive symptoms of mothers with the presence of anaemia in their children., Methods: Analytical cross-sectional study of the Peruvian Demographic Health Survey 2015, which is nationally representative. Depressive symptoms were measured with the Patient Health Questionnaire-9 (PHQ-9) using a score of 10 as cut-off. The presence of anaemia was measured using HemoCue® and was considered positive when the haemoglobin was less than 11 g/dl., Results: Crude and adjusted prevalence ratios (PR and aPR) were calculated with 95% confidence interval (CI), using generalized linear models of the Poisson family. We analysed 6683 mother-child binomials. The prevalence of anaemia in the children and depressive symptoms in women were 28.7% (95% CI: 27.3-30.2) and 6.9% (95% CI: 6.1-7.9), respectively. We found no statistically significant association between these variables in the bivariable analysis or in the different multivariable models (aPR: 1.05, 95% CI: 0.85-1.30). The sample did not have moderate or severe malnutrition., Conclusions: There is no statistically significant difference between the prevalence of anaemia in children of mothers with or without depressive symptoms. We recommend continuing research in this field to determine more associate factors to childhood anaemia in order to improve primary prevention interventions. Ideally, conducting longitudinal studies such as prospectives cohorts to determine risk factors should be done., (© 2020 John Wiley & Sons, Ltd.)

Breast cancer (BC) screening could reduce its mortality; however, its access is influenced by societal forces. Our objective is to identify the social determinants associated with mammography screening (MS) in women aged 50 to 59 in Peru. In this cross-sectional analysis of the Peruvian Demographic Health Survey, 2015, MS within the past two years was evaluated through self-report. Prevalence for MS was 21.9% [95% CI: 18.9 to 25.1]. The average age was 54 years (s.d.: 2.5). The higher the socioeconomic status, the higher the prevalence of screening (3.2% vs 41.4% in extreme quintiles, p  < .001). In the adjusted models, higher socioeconomic status (PR: 5.81, 95% CI: 2.28 to 14.79), higher education level (PR: 2.03, 95% CI: 1.30 a 3,15) and having health insurance from the Ministry of Health (PR: 2.21, 95% CI: 1.28 to 3.82) and EsSalud (PR: 4.37, 95% CI: 2.67 to 7.15), were positively associated with MS. Social inequalities in screening access exist and might translate into inequalities in cancer morbidity and mortality. The Peruvian government urgently needs to improve screening rates in these vulnerable populations.

Madariaga virus (MADV) has recently been associated with severe human disease in Panama, where the closely related Venezuelan equine encephalitis virus (VEEV) also circulates. In June 2017, a fatal MADV infection was confirmed in a community of Darien Province. We conducted a cross-sectional outbreak investigation with human and mosquito collections in July 2017, where sera were tested for alphavirus antibodies and viral RNA. In addition, by applying a catalytic, force-of-infection (FOI) statistical model to two serosurveys from Darien Province in 2012 and 2017, we investigated whether endemic or epidemic alphavirus transmission occurred historically. In 2017, MADV and VEEV IgM seroprevalences were 1.6% and 4.4%, respectively; IgG antibody prevalences were MADV: 13.2%, VEEV: 16.8%, Una virus (UNAV): 16.0%, and Mayaro virus: 1.1%. Active viral circulation was not detected. Evidence of MADV and UNAV infection was found near households, raising questions about its vectors and enzootic transmission cycles. Insomnia was associated with MADV and VEEV infections, depression symptoms were associated with MADV, and dizziness with VEEV and UNAV. Force-of-infection analyses suggest endemic alphavirus transmission historically, with recent increased human exposure to MADV and VEEV in Aruza and Mercadeo, respectively. The lack of additional neurological cases suggests that severe MADV and VEEV infections occur only rarely. Our results indicate that over the past five decades, alphavirus infections have occurred at low levels in eastern Panama, but that MADV and VEEV infections have recently increased-potentially during the past decade. Endemic infections and outbreaks of MADV and VEEV appear to differ spatially in some locations of eastern Panama.

The aim of this study was to describe the frequency of migration to study medicine in Peru. We con ducted a secondary data analysis of the Red-LIRHUS study (2011-2012). We included 3 680 Peruvian students. Approximately, 23.2% migrated for medical school. Less than 1% were international migrants. We found a higher proportion of migrant students in Universities outside of Lima than in Universities in Lima (27.1% vs. 15.8%). There was also a higher proportion of migrants in private universities (28.3% vs. 16.0%) Migrant students were more likely to live alone (27.4% vs. 6.4%) and to report having failed a module/course (51.0% vs. 38.6%) compared to non-migrant students. It is necessary to evaluate potential interventions for the preservation of the well-being of people who migrate for their medical training.

The worldwide scarcity of psychiatrists makes the identification of the factors associated with the intention to choose this specialty an important issue. This study aims to evaluate the association between religious affiliation and the intention to choose psychiatry as a specialty among medical students from 11 Latin American countries. We conducted a cross-sectional, multi-country study that included first- and fifth-year students of 63 medical schools in 11 Latin-American countries between 2011 and 2012. The main outcome and measures were the intention to pursue psychiatry as a specialty over other specialties (yes/no) and religious affiliation (without: atheist/agnostic; with: any religion). A total of 8308 participants were included; 53.6% were women, and the average age was 20.4 (SD = 2.9) years. About 36% were fifth-year students, and 11.8% were not affiliated with any religion. Only 2.6% had the intention to choose psychiatry; the highest proportion of students with the intention to choose psychiatry was among students in Chile (8.1%) and the lowest among students in Mexico (1.1%). After adjusting for demographic, family, academic as well as personal and professional projection variable, we found that those who had no religious affiliation were more likely to report the intention to become a psychiatrist [OR: 2.92 (95%CI: 2.14-4.00)]. There is a strong positive association between not having a religious affiliation and the intention to become a psychiatrist. The possible factors that influence this phenomenon must be evaluated in greater depth, ideally through longitudinal research.

Background: The doctor-patient relationship may be affected by the indiscriminate use of social media platforms. The aim of this study was to evaluate the content of the photos posted on medical students' Facebook accounts to determine whether they have posted private patient information and compare this to their self-reported behavior of posting such photos. Methods: We performed a cross-sectional study of medical students from a Peruvian private university. With their permission, we reviewed their Facebook accounts for the publication of photos or documents that included private patient information (face, name, diagnosis, medical exams). Those who allowed access to their Facebook accounts were also asked to complete an online survey. We assessed variables related to sociodemographic aspects, self reported Facebook use, and what type of private patient information they posted. Results: A total of 160/220 students joined the study, 59% were women, mean age: 20 years. 25.7% self-reported having posted private patient information in their Facebook profiles but we found such information on 33.1% of the students' pages. Of the pages where private patient information was found, in 94% of cases, the patients' faces were identifiable, and in 7.6%, the patients' real names appeared. However, only half of the students believed that the information in their Facebook post might affect or influence the doctor-patient relationship. Association with narcissism, gender, and account privacy was not found. Having uploaded more than 250 photos (OR:2.90; CI95%:1.14-7.39) and posting photos tagged with the location of a hospital (OR:4.02; CI95%:1.36-11.9) were associated with having posted photos containing private patient information. Conclusion: One out of three of medical students posted patients' private information on their personal Facebook profiles. Development, dissemination, and implementation of guidelines related to ethics in social media platforms are needed.

Objectives.: To explore female authorship trends among the articles published in the Revista Peruana de Medicina Experimental y Salud Pública between 1997 and 2017, as well as its association with characteristics of the research teams., Materials and Methods.: We conducted a bibliometric analysis. We evaluated time trends of several forms of female participation in authorship, including "privileged authorship roles" (first author, corresponding author and senior author) and the proportion of female authors (out of the total number of authors). We compared female authorship according to the participation of medical doctors and authors from non-Peruvian institutions., Results.: We analysed 1606/1621 articles; 46.3% were original articles. 63.5% had at least one female author, whilst 92.8% had at least one male author. A woman was the first, corresponding or senior author in 29.6%, 27.8% and 26.9% of the articles, respectively. 33% of authors per article were female (median). These figures did not considerably vary between the start and end of the study period. For original articles, female authorship was less likely if medical doctors were listed in the privileged authorship roles and more likely, if authors from non-Peruvian institutions were. Editorial processing times were longer when a woman served a privileged authorship role., Conclusions.: Women served privileged authorship roles in less than a third of all articles. Apparently, these gaps have not improved over time. The composition of the research team predicts female authorship.

Peruvian research output is one of the lowest in South America and is limited to the work of a small group of institutions and related to few subjects, such as infectious diseases. We determined the proportion of subsequent publication and its associated factors of the abstracts with Peruvian affiliation presented to the American Society of Tropical Medicine and Hygiene annual meetings between 2006 and 2010. Approximately 27% (79/296) of abstracts were published within 6 years of presentation, with a median time to publication of 16 months (interquartile range: 9-28). In the adjusted analysis, abstracts with a higher proportion of authors from Peruvian institutions were less likely to be published (risk ratio: 0.5; 95% CI: 0.3-0.8). In conclusion, one of four of the analyzed abstracts was published. Even though this proportion is higher than that in other meetings in Peru and South America, publication rates -especially among Peruvian-only collaborations- still need to be improved.

Background: Studies assessing the association between vegetarianism and mental health have found divergent results. Evidence from adolescents in developing countries is scarce., Objective: To evaluate the association between a vegetarian diet and emotional symptoms in 15-year-old adolescents from Ethiopia, India, Peru and Vietnam., Methods: A cross-sectional, secondary analysis of the Young Lives cohort study was used. The exposure variable was the self-report of being a vegetarian (yes or no). The outcome was the level of emotional symptoms, numerically evaluated using the score obtained in the subscale "Emotional Symptoms" of the Strengths and Difficulties Questionnaire (SDQ). We calculated crude and adjusted coefficients (β) with 95% confidence intervals (95% CIs), using generalized linear models of the Gaussian family, considering each sentinel site as a cluster. The analysis was stratified by country. Additionally, we made a global analysis including the four countries., Results: A total of 3484 adolescents were analyzed. The overall prevalence of vegetarianism was 4.4%, but it varied between countries (from 0.4% in Vietnam to 11.5% in India). The average emotional symptoms score was 3.5 [standard deviation (SD) 2.3] points. The scores were not statistically different between vegetarians and non-vegetarians (p > 0.05). In the adjusted analysis, in Vietnam, vegetarians had lower emotional symptoms scores on average than non-vegetarians [β: -1.79; 95% CI: -3.05 to -0.55]. No differences were found neither in the other countries nor in the overall sample., Conclusion: There was no association between a vegetarian diet and emotional symptoms in the analyzed adolescents of four developing countries., (©2018 Walter de Gruyter GmbH, Berlin/Boston.)

Objectives: To describe the prevalence and factors associated with the purchase of antimicrobials without a prescription (CASRM) in drugstore/pharmacy users according to the National Health User Satisfaction Survey (ENSUSALUD)., Materials and Methods: A secondary analysis of ENSUSALUD 2016 was carried out; a study with two-stage probabilistic sampling in the Health Service Providers of the public and private subsector. The CASRM was evaluated by self-report. Crude (PR) and adjusted (PRa) prevalence ratios with 95% confidence intervals (95% CI) were estimated., Results: The study included 1.165 users who purchased antimicrobials. The mean age was 38.0 years (standard deviation: 13.4). The prevalence of CASRM was 53.4% (95% CI: 48.0-58.8). The prevalence of CASRM in the highlands was (PRa 1.66, 95% CI 1.37-2.02) and in the jungle (PRa 1.61, 95% CI 1.31-1.99); and in pharmacy users (PRa 1.25, 95% CI 1.13-1.39). People with Comprehensive Health Insurance (SIS) had a lower prevalence of CASRM (RP 0.73, 95% CI 0.60-0.88). The prevalence was lower if the antimicrobial was for the spouse (RP 0.65, 95% CI 0.55-0.77) or child (RP 0.70, 95% CI 0.52-0.93)., Conclusions: A 53.4% of drugstore/pharmacy users, who bought antimicrobials, did so without a doctor's prescription. The prevalence of CASRM was higher in the highlands and jungle and in pharmacy users, as well as lower in those who had SIS and those who bought for their spouse or child. We suggest reinforcing the interventions, mainly regulatory and educational, in the highlands and in the jungle, as well as, in the population not affiliated to a health insurance.

Introduction: Health professionals performing their social health service (SHS) in rural communities could be at risk of developing depression. Moreover, those who migrate from farther places to perform their SHS could have an increased risk. The objective of this study was to evaluate the association between place of origin and the presence of depressive symptoms, in health professionals performing rural social health service (SHS) in Ancash, Peru., Methods: This was a cross-sectional study. During April 2015, a survey was applied to health professionals performing SHS in the Peruvian Ministry of Health (MINSA) facilities in Ancash. The main outcome was the presence of depressive symptoms, defined as a score &ge;2 points in the Patient Health Questionnaire-2. The main exposure was the place of origin, defined as the place where the subjects completed their undergraduate professional studies (Ancash, Lima city or others). Poisson regressions with robust variance were performed to calculate crude and adjusted prevalence ratios (PR and aPR) and their 95% confidence interval (95%CI)., Results: From 573 health professionals performing their SHS in MINSA in Ancash, 347 were included in the study. The mean age was 27.2&plusmn;4.5 years, 78.7% were women, and 14.7% scored positive for depressive symptoms. Those who had completed their undergraduate professional studies in Lima city had a higher prevalence of presence of depressive symptoms compared to those who did in Ancash (aPR=2.59, 95%CI=1.23-5.45)., Conclusions: Those who completed their undergraduate professional studies in Lima had a higher prevalence of depressive symptoms than those who did in Ancash. Possible explanations include the difficulty in visiting family and friends, acculturation, and lack of Quechua language proficiency.

Background: Latin America is undergoing a human resource crisis in health care in terms of labor shortage, misdistribution and poor orientation to primary care. Workforce data are needed to inform the planning of long-term strategies to address this problem. This study aimed to evaluate the academic and motivational profile, as well as the professional expectations, of Latin American medical students., Results: We conducted an observational, cross-sectional, multi-country study evaluating medical students from 11 Spanish-speaking countries in 2011-2012. Motivations to study medicine, migration intentions, intent to enter postgraduate programs, and perceptions regarding primary care were evaluated via a self-administered questionnaire. Outcomes were measured with pilot-tested questions and previously validated scales. A total of 11,072 valid surveys from 63 medical schools were gathered and analyzed., Conclusions: This study describes the profile and expectations of the future workforce being trained in Latin America. The obtained information will be useful for governments and universities in planning strategies to improve their current state of affairs regarding human resources for health care professions.

Introduction: The selection of a medical specialty has been associated with multiple factors, such as personal preferences, academic exposure, motivational factors and sociodemographic factors, such as gender. The number of women in the medical field has increased in recent years. In Latin America, we have not found any studies that explore this relationship., Objective: To determine whether there is an association between gender and the intention to choose a medical specialty in medical students from 11 countries in Latin America., Methods: Secondary analysis of the Collaborative Working Group for the Research of Human Resources for Health (Red-LIRHUS) data; a multi-country project of students in their first year and fifth year of study, from 63 medical schools in 11 Latin American countries. All students who referred intention to choose a certain medical specialty were considered as participants., Results: Of the 11073 surveyed students, 9235 indicated the name of a specific specialty. The specialties chosen most often in the fifth year were General Surgery (13.0%), Pediatrics (11.0%), Internal Medicine (10.3%) and Obstetrics/Gynecology (9.0%). For women, the top choices were Pediatrics (15.8%), Obstetrics/Gynecology (11.0%), Cardiology (8.7%), General Surgery (8.6%), and Oncology (6.4%). In the adjusted analysis, the female gender was associated with the choice of Obstetrics/Gynecology (RP: 2.75; IC95%: 2.24-3.39); Pediatric Surgery (RP: 2.19; IC95%: 1.19-4.00), Dermatology (RP: 1.91; IC95%:1.24-2.93), Pediatrics (RP: 1.83; IC95%: 1.56-2.17), and Oncology (RP: 1.37; IC95%: 1.10-1.71)., Conclusions: There is an association between the female gender and the intention to choose Obstetrics/Gynecology, Pediatrics, Pediatric Surgery, Dermatology, and Oncology. We recommend conducting studies that consider other factors that can influence the choice of a medical specialty.

Background: The shortage in Latin-American Primary Care (PC) workforce may be due to negative perceptions about it. These perceptions might be probably influenced by particular features of health systems and academic environments, thus varying between countries., Methods: Observational, analytic and cross-sectional multicountry study that evaluated 9,561 first and fifth-year medical students from 63 medical schools of 11 Latin American countries through a survey. Perceptions on PC work was evaluated through a previously validated scale. Tertiles of the scores were created in order to compare the different countries. Crude and adjusted prevalence ratios were calculated using simple and multiple Poisson regression with robust variance., Results: Approximately 53% of subjects were female; mean age was 20.4±2.9 years; 35.5% were fifth-year students. Statistically significant differences were found between the study subjects' country, using Peru as reference. Students from Chile, Colombia, Mexico and Paraguay perceived PC work more positively, while those from Ecuador showed a less favorable position. No differences were found among perceptions of Bolivian, Salvadoran, Honduran and Venezuelan students when compared to their Peruvian peers., Conclusions: Perceptions of PC among medical students from Latin America vary according to country. Considering such differences can be of major importance for potential local specific interventions.

Objetives: The aim of this study is to evaluate the association between the time of outsourced work and the development of pneumoconiosis in Peruvian miners who attended the "Centro Nacional de Salud Ocupacional y Protección al Ambiente para la Salud" between 2008 and 2011., Materials and Methods: Retrospective case-control study. Cases were defined as workers diagnosed of pneumoconiosis under standardized criteria. Outsourced work was defined as the time (in months) of work in a company that does not own the primary mining project. The project owner company was registered in the Mining Companies Directory (Ministerio de Energía y Minas). We used multiple logistic regression with crude and adjusted ORs., Results: The study comprised 391 cases and 1519 controls. In both groups, most of the study subjects had a level of education lower than complete high school and were born and currently lived in the Peruvian highlands. There was statistically significant association between more frequency of pneumoconiosis and working 10 or more years in an outsourced company (OR: 1.50; 95%CI: 1.05-1.14; p=0.026). Miners with pneumoconiosis were more likely not to have education (OR: 3.07; 95%CI: 1.55-6.08; p=0.001), be currently living at the Peruvian highlands (OR: 1.40; 95%CI: 1.10-1.78; p=0.007) and to have more than 20 years of underground work history (OR: 8.92; 95%CI: 4.53-18.25; p<0.001)., Conclusions: A statistically significant association was found between pneumoconiosis and the time of outsourced work. Not having education, residing in the Peruvian highlands and the time of underground work were associated risk factors.

Introduction: We sought to evaluate the intentions of Honduran medical students to emigrate or to work in a rural setting, and their association with parental education., Methods: We performed a cross-sectional, analytic study at a Honduran medical school. Student participants completed a structured questionnaire, which assessed their intentions to emigrate or work in a rural setting after finishing medical school and the highest level of education achieved by their parents. We calculated crude and adjusted prevalence ratios with their respective 95% confidence intervals., Results: Of 868 surveys distributed, 564 were completed. The mean age of the participants was 21 (standard deviation 3) years, and 62.2% were female. Of the respondents, 16.6% intended to emigrate to work and 11.2% intended to work in a rural setting. Higher paternal education (i.e., technical, university and postgraduate training) was associated with a higher rate of intention to emigrate. Students whose fathers underwent postgraduate education were less likely to intend to work in a rural setting. For maternal education, only the postgraduate level was associated with the outcomes in some of the tested models., Conclusion: The frequency of students intending to emigrate was relatively low. However, the frequency of students being willing to work in rural settings was also low. Students whose parents had higher levels of education were more likely to intend to work abroad and less likely to intend to work in a rural area. These factors should be considered in medical schools' selection processes to improve retention and ensure adequate distribution of physicians.

Objectives: To evaluate the frequency of publication and its associated factors by professors of scientific research in medical schools in Peru., Materials and Methods: This was a cross-sectional study. We included all teachers of research courses from the 32 medical schools in Peru in 2011. The publication search was conducted using Google Scholar, Scopus and Medline. Both the crude and adjusted prevalence ratios (aPR) were calculated with confidence intervals at 95% using simple and multiple Poisson regression with robust variance., Results: Of the 201 university teachers, 43.8% had never published an article in a journal, 26.9% had an original article published in a journal indexed in Medline and 16.4% did so in the past two years. Only 3% had been corresponding authors in non-Peruvian, indexed journals Factors associated with having an original article published in Medline in the past two years were: being under 40 years of age (aPR 2.97, 95% CI: 1.21-7.32), being a professor at a university where a final thesis is required for graduation (aPR 8.84, 95% CI: 2.60-30.12) and working for a highly productive university (aPR 3.24, 95% CI: 1.03-10.20)., Conclusions: The frequency of publication of research faculty in medical schools in Peru is low. Young university teachers and those working at scientifically productive universities were more likely to publish in an indexed journal.

Background: Learning research skills should be a goal during undergraduate training of physicians., Aim: To identify Latin American medical students' appraisal on research skills university training., Material and Methods: A self-administered survey about experience in research, self-assessment of research skills, quality of training in the area received at the university and that importance of publishing as undergraduate students, was answered by 208 medical students aged 23 ± 3 years (54% male), attending a medical students congress., Results: Seventy percent of respondents pertained to medical students' scientific societies and 34% had published in a scientific journal. Fifty two percent considered as good or very good the training level received at their universities on information retrieval and 45% considered good the training in research methodology. Thirty two percent considered as poor or none the training received in scientific writing and 37% in the publishing process. Eighty nine percent considered student publishing as important and 61% perceived limitations in this matter., Conclusions: The university training level received by Latin American medical students on research and publication process was evaluated as deficient by these students.

Objectives: To design and validate a scale to assess Latin American medical students' perception on first level of health care (FLHC)., Materials and Methods: An observational, analytic and multicentre study was carried out in two phases: i) A self-administered questionnaire regarding perceptions on FLHClabor was designed. ii) This questionnaire was applied to to medical students from 18 universities of eight Spanish-speaking Latin American countries. An exploratory factor analysis (EFA) was performed through a principal components analysis with orthogonal varimax rotation. Sample adequacy was evaluated. Factor extraction was based on Kaiser's criteria, Cattell's Scree test and the explained variance (>5%). Internal consistency was measured with Cronbach's alpha., Results: 423 students were included in the analysis; 53.4% were from Peruvian universities. After the EFA, the questionnaire conserved 11 items, which were distributed in three domains, that explaining together 55.47% of the total variance: i) Perceptions concerning the FLHC physician; ii) Perceptions concerning the FiLC labor and iii) Perceptions about the economic consequences of working in FLHC., Conclusion: The scale is composed by three domains and can be used to assess the perceptions of the medical work on first level of health care of Spanish-speaking Latin American medical students.

Objectives: To determine the publication rate of abstracts submitted at the national scientific meetings of medical students in Peru between 2002 and 2009, and associated factors., Materials and Methods: A retrospective cohort was performed; the characteristics of overall abstract submitted were assessed. In addition, whether they were published in scientific journals was determined by way of a search strategy validated using Google Scholar. Crude and adjusted relative risks (RR) were calculated using Poisson regression with robust variance to assess association with the analyzed factors., Results: 532 abstracts were analyzed, 52 (9.8%) of which were published in scientific journals after their presentation at a scientific meeting. All of them were published in Peruvian journals written in Spanish. The most important journal in which they were published was Ciencia e Investigación Médica Estudiantil Latinoamericana (CIMEL) (13/52). The median of publication time was 13 months (range: 0-75). The fact that a student from the Universidad Nacional Mayor de San Marcos (RR: 5.18; CI95%:2.3-11.6) is the author of the abstract and that the abstract was collaboratively written by students from two universities (RR: 3.64; CI95%:1.1-11.7) are associated factors in the multivariate analysis., Conclusions: The publication rate of abstract submitted at national scientific meetings of medical students in Peru is low. New strategies should be taken, and the existing ones should be reinforced in order to increase the publication rate of the abstract submitted.

Objectives: To determine the proportion of abstracts presented at the Congreso Peruano de Gastroenterología (the major Peruvian gastroenterological scientific meeting), that had been published in scientific journals, the date of publication and its associated factors., Materials & Methods: Longitudinal retrospective and analytic study; the publicationrate of all the abstracts presented in the biennial Congreso Peruano de Gastroenterología between 1998 and 2008 was assessed. Google Scholar engine was used. The searching strategy performed included: ("Study location" AND "population studied" AND "main outcome") AND (autor:First OR autor:Second OR autor:Last). Logistic regression was used, considering p<0.05 statistically significant., Results: Publication rate was 8.2% (34/217), statistically significant differences were found among meeting years (p<0.001). There were also differences between study design, objectives (more in analytic studies) and measurement (more in longitudinal studies (p<0.001). 82.4% were published in the Revista de Gastroenterología del Perú. The median time for publication was 10.8±10.4 months; this variable and the meeting year, study type, journal of publication or accordance between the abstract and publication characteristic showed no statistical differences. The mean authors' number was 5.02±2.4; analytic studies have less authors than the descriptive ones (3.6 vs 6.1; p=0.012)., Conclusion: The Congreso Peruano de Gastroenterología presents a low publication rate of the abstracts presented, which can be used as a quality indicator of the abstracts and the reviewing process.

Introduction: Depressive symptoms in health sciences students are common, these might be potentially detrimental., Objectives: To determine the prevalence of depressive symptoms and its associated factors in students from the Health Sciences Faculty of the Universidad Peruana de Ciencias Aplicadas in Lima (Peru), June 2010., Materials and Methods: Cross-sectional analytic study; a pre-consented survey was applied to the population 590/869 students. Zung's abbreviated scale was used to measure depressive symptoms. To evaluate de associated factors, logistic regression was used, p<0.05 was considered statistically significant., Results: The mean age was 18.97 ± 2.45 years and 71.1% were women, 19.6% were migrants and 62.5% were medical students. The prevalence of depressive symptoms was 31.2% in the whole population and in medical students was 33.6%. Depressive symptoms were not associated in bivariate analysis with sex, career, having failed a course, living alone or being a migrant (p>0.05). In the multivariate analysis, significant statistical association was found between depressive symptoms and dissatisfaction with the own academic performance (OR=2.13 CI95%1.47-3.08), dissatisfaction with the current economic status (OR=1.93 CI95%1.24-2.99) and living with a relative external to the nuclear family (OR=1.62 CI95%1.07-2.45)., Conclusion: A high prevalence of depressive symptoms was found, especially in medical students; being dissatisfaction with academic performance, economic status and living with a relative external to the nuclear family associated factors that could be taken into account in order to build preventive programs.
