Stakeholders' Perceptions on the Implementation of the HPV Vaccine School-Entry Requirement in Puerto Rico during the COVID-19 Pandemic.

This study explored the implementation of the human papillomavirus (HPV) vaccine school-entry requirement in Puerto Rico during the COVID-19 pandemic. We conducted 26 semi-structured interviews with stakeholders and community-based organizations from August 2021 to March 2022. The interview guide was developed using the 2009 Consolidated Framework for Implementation Research (CFIR). The interviews were recorded and transcribed in Spanish. Data were analyzed using applied thematic techniques. These themes included the following: (i) Intervention characteristics: Participants noted that the school-entry requirement was effective in increasing vaccination uptake prior to the pandemic. Issues with the immunization registry were noted; (ii) Outer setting: External influences, access barriers, and an increase in HPV vaccine exemptions since the implementation of the COVID-19 vaccine were discussed; (iii) Inner setting: Communication within organizations and HPV vaccination efforts improved as the pandemic progressed; (iv) Characteristics of individuals: Most agreed with the school-entry requirement, including exemptions; and (v) Process: Results showed the need to reinforce the population's education about HPV and the vaccine. Implementation of the policy was challenging during the early stages of the pandemic due to measures enacted to stop the spread of COVID-19 and focus on the COVID-19 vaccine. Efforts to increase HPV vaccine should focus on increasing HPV vaccine education and creating collaborations.

Attitudes towards HPV and COVID school-entry policies among adults living in Puerto Rico.

Prior to the COVID pandemic, Puerto Rico (PR) had one of the highest Human Papillomavirus (HPV) vaccine rates in the United States. The COVID pandemic and administration of COVID vaccines might have impacted attitudes toward HPV vaccination. This study compared attitudes toward HPV and COVID vaccines with respect to school-entry policies among adults living in PR. A convenience sample of 222 adults (≥21 years old) completed an online survey from November 2021 to January 2022. Participants answered questions about HPV and COVID vaccines, attitudes toward vaccination policies for school-entry, and perceptions of sources of information. We assessed the magnitude of association between the agreement of school-entry policies for COVID and HPV vaccination by estimating the prevalence ratio (PRadjusted) with 95% Confidence Intervals (95% CI). The most trusted source of information for HPV and COVID vaccines were healthcare providers (42% and 17%, respectively) and the CDC (35% and 55%, respectively), while the least trusted were social media (40% and 39%, respectively), and friends and family (23% n = 47, and 17% n = 33, respectively). Most participants agreed that HPV (76% n = 156) and COVID vaccines (69% n = 136) should be a school-entry requirement. Agreement with school policy requiring COVID vaccination was significantly associated with agreement of school policy requiring HPV vaccination (PRadjusted:1.96; 95% CI:1.48-2.61) after controlling for potential confounders. Adults living in PR have an overall positive attitude about mandatory HPV and COVID vaccination school-entry policies, which are interrelated. Further research should elucidate the implications of the COVID pandemic on HPV vaccine attitudes and adherence rates.

Human papillomavirus vaccine initiation and up-to-date vaccine coverage for adolescents after the implementation of school-entry policy in Puerto Rico.

The human papillomavirus (HPV) vaccine has been proven effective in the prevention of infection with high-risk HPV types, which can lead to the development of six HPV-related cancers. Puerto Rico (PR) adopted a mandatory HPV vaccination school-entry policy that took effect in August 2018. While school-entry requirements are generally accepted as an effective approach for increasing vaccination rates, there are few studies that have documented their impact on improving HPV vaccination rates. The objective of this study was to evaluate the impact of the HPV school-entry policy in PR on HPV vaccine coverage. We used a pre-post natural experiment. The study population included adolescents registered in the PR Immunization Registry during 2008-2019. We calculated HPV vaccine initiation and up-to-date (UTD) vaccine coverage rates. We estimated age-standardized rates (ASR) and standardized rate ratio with 95%CI. Vaccine data corresponding to a total of 495,327 adolescents were included for analysis; 50.9% were male and 49.1% were females. After policy implementation, a marked increase in raw HPV vaccine initiation among 11- to 12-year-old adolescents was observed across years 2017 (a pre-policy year), 2018, and 2019 (58.3%, 76.3%, and 89.8%, respectively). UTD coverage also showed a moderate increase after policy implementation among 11- to 12-year-old adolescents. The gap between sexes in vaccine initiation and UTD coverage narrowed over time; the ASRs in 2019 showed an increase of 19% in initiation and 7% increase in UTD relative to 2017 for males and females combined (both significant at p<0.05). This study demonstrated evidence of improvement in HPV vaccination rates following implementation of the school-entry policy and a narrowed sex gap in vaccine rates over time in PR. Future analyses should assess how the policy continues to affect vaccine coverage in subsequent years and how the COVID-19 pandemic has impacted HPV vaccination uptake.

Effect of Hurricane Maria on HPV, Tdap, and meningococcal conjugate vaccination rates in Puerto Rico, 2015-2019.

In September 2017, Hurricane Maria devastated the Caribbean region, among them the US territory of Puerto Rico (PR). Vaccination distribution and uptake suffered from the impact. This study evaluated the trends in monthly vaccination initiation rates for human papilloma virus (HPV), Tdap and meningococcal conjugate (MenACWY) adolescent vaccines from 2015 to 2019, during which it was possible to observe and analyze the impact of Hurricane Maria on vaccine initiation. Monthly initiation rates were estimated. Age-standardized initiation rate ratio (SRR) and 95% CI were estimated. The analysis included 85,340 adolescents; 52.3% were male, and 47.7% were females. September 2017 showed HPV vaccine initiation had the lower rates of all the studied vaccines, with a rate of 75% after the disaster (from a rate of almost 90% in July 2017). Tdap and MenACWY vaccines rates remained above 90% in the same period. The SRR of HPV vaccine for September and October 2017 showed an estimated reduction of 5% and 8% in vaccine initiation rates, respectively for each month, when 2016 was the reference year (p > .05). The SRR of Tdap and MenACWY vaccines for November 2017 showed significant reductions when 2015 and 2016 were reference years (p < .05). HPV vaccine initiation rate was the most severely affected by the Hurricane Maria. Post-natural disaster protocols should strengthen existing programs for facilitate immunization access.

Understanding parents' views toward the newly enacted HPV vaccine school entry policy in Puerto Rico: a qualitative study.

BACKGROUND: The Human papillomavirus vaccine (HPV) is an essential tool for the prevention of HPV-related cancers. In Puerto Rico, the Secretary of Health established a school entry requirement of at least one dose of HPV vaccination in girls and boys aged 11 and 12 years, taking effect in August 2018. Our study aimed to examine parents' and guardians' views of unvaccinated children about the process of implementation of the new HPV vaccination school entry policy in Puerto Rico and identify potential barriers and facilitators related to the implementation of this requirement. METHODS: During April through November 2019, we conducted three focus groups (n = 12) and eight in-depth semi-structured interviews with parents of children aged 11 and 12 who had not yet initiated the HPV vaccine series. The interview topics addressed were: perception of vaccination, HPV vaccine and it is inclusion as new school entry requirement practice, procedure of the sources of information, influencers, and willingness to change. The interviews were recorded and transcribed by our staff members. We identified emergent themes through thematic analysis. RESULTS: The participants' perspective on the HPV vaccine school requirement was mixed. Lack of information of the HPV vaccines and lack of communication about the school-entry requirement were the themes most mentioned in the interviews. Moreover, previous negative experiences from friends or family members and adverse effects deterred some participants from vaccinating their kids. We discussed barriers in the process of soliciting an exemption. CONCLUSION: Most barriers mentioned by study participants are modifiable. Information about the HPV vaccine mandate's implementation and educational materials regarding HPV vaccine safety need to be provided to address parents' concerns related to the vaccine's side effects. Schools (teachers, principal directors, and administrative staff), the government, and parent organizations need to be part of these efforts. This multilevel approach will help to improve disseminating information about HPV vaccination to clarify doubts and misinformation among parents.

Implementation of the human papillomavirus school-entry requirement in Puerto Rico: barriers and facilitators using the consolidated framework for implementation research.

In 2018, Puerto Rico (PR) enacted a Human papillomavirus (HPV) vaccine school-entry requirement for students ages 11 to 12. Using the Consolidated Framework for Implementation Research (CFIR), we aimed to identify potential barriers and facilitators of this implementation. We conducted 38 qualitative interviews with stakeholders in PR from different organizations (Department of Health, Schools, Healthcare Providers, and Community organizations). We evaluated construct rating variability between the organizations to determine barriers and facilitators. The strongest facilitator determined was stakeholder's awareness of the parent's and student's needs to meet the HPV school-entry requirement. Other facilitators included initiatives for school-entry policies and the relative advantage of this requirement over different strategies. The strongest barriers included was the cost for private providers to administer the HPV vaccine, the negative influence of social media about the vaccine, which affected parents' acceptance, and the lack of school nurses as available staff resources for the school entry requirement. Findings from this study can be used to improve implementation (adaptations/modifications) and inform other states and countries in earlier stages of consideration of the adoption of similar immunization policies. Most barriers can be modifiable with the implementation of educational programs/training across schools, considering that they are the first line of response to parents of this school entry requirement.

Content analysis of digital media coverage of the human papillomavirus vaccine school-entry requirement policy in Puerto Rico.

BACKGROUND: In August 2018, Puerto Rico (PR) became the 4th state or territory in the United States to adopt a human papillomavirus (HPV) vaccine school-entry requirement, for students 11-12 years old. Evidence suggests that the content of media coverage may impact people's perception of HPV vaccine and their willingness to vaccinate. This study aimed to analyze the content of digital news coverage related to the implementation of the policy in PR. METHODS: A content review was conducted of digital media published from January 2017 through December 2018. The content reviewed was carried out in two steps: 1) creating a matrix to summarize each article's content about the policy and 2) qualitative analysis using a grounded theory approach. RESULTS: The search resulted in 34 articles obtained from 17 online local and international news outlets that reported the policy's implementation. Analyses showed that 61% of the news articles did not mention the number of required doses, and 79% discussed the new policy concerning cancer prevention. In 2017, news coverage focused mostly on describing the policy, while 2018 coverage focused on controversies surrounding the implementation. Neutral emergent codes included: 1) Description of the policy; 2) Information about HPV related cancers; and 3) General information about HPV vaccine. Negative emergent codes included: 1) infringement to patient and parental autonomy; 2) Hesitancy from the political sector, and 3) Hesitancy from groups and coalitions. Positive content included: 1) knowledge and acceptance of HPV vaccine for cancer prevention; 2) importance of education and protective sexual behaviors; and 3) new vaccination law proposal. CONCLUSIONS: Most of the media coverage in PR was neutral and included limited information related to the vaccine, HPV, and HPV-related cancers. Neutral and negative themes could influence public concerns regarding the new policy, as well as HPV vaccination rates in PR.

Identification of a Huperzine A-producing endophytic fungus from Phlegmariurus taxifolius.

Highly prized huperzine A (Hup A), a natural alkaloid formerly isolated from the Chinese medicinal plant Huperzia serrata, has been widely used for the treatment of Alzheimer disease, inspiring us to search for endophytic fungi that produce this compound. In this study, we obtained the C17 fungus isolate from the Mexican club moss Phlegmariurus taxifolius, which produced a yield of 3.2 µg/g Hup A in mycelial dry weight, when cultured in potato dextrose broth medium. The C17 isolate was identified as belonging to the genus Fusarium with reference to the colony´s morphological characteristics and the presence of macroconidia and microconidia structures; and this was confirmed by DNA-barcoding analysis, by amplifying and sequencing the ribosomal internal transcribed spacer (rITS).

Manejo insulínico de la gestante con tolerancia a la glucosa potencialmente alterada / Handling of the pregnant woman with tolerance to high levels of glucose

FUNDAMENTO: la tolerancia a la glucosa potencialmente alterada se asocia a una morbimortalidad materna y fetal estadísticamente similar a la diabetes gestacional. OBJETIVO: valorar los resultados del uso profiláctico de la insulina en pacientes con tolerancia a la glucosa potencialmente alterada con malos antecedentes obstétricos. MÉTODO: se realizó un estudio de intervención con el uso de la insulina profiláctica en gestantes con tolerancia a la glucosa potencialmente alterada con malos antecedentes obstétricos, en el Hospital Universitario Ginecobstétrico Ana Betancourt de Mora de Camagüey, desde enero de 2009 a diciembre de 2010. El universo fue de 179 gestantes y la muestra no probabilística de 25. RESULTADOS: antes de la intervención 22 pacientes no tenían hijos, de estas 16 pasaban los 30 años sin hijos vivos. Como factores de riesgos familiares, la diabetes mellitus tipo 2 representó el 56 %, todas las pacientes tuvieron dos o más riesgos obstétricos donde predominaron el aborto habitual y la muerte fetal. Todas las pacientes presentaron la glucemia en la captación mayor de 4,4 mmol/L, normales las pruebas de tolerancia a la glucosa y el sobrepeso materno constituyó el 44 %. Luego de aplicado el tratamiento insulínico a las pacientes, 20 gestantes llegaron al término de la gestación, hubo dos partos pretérmino, dos abortos y un óbito fetal. No hubo muerte neonatal. Una paciente luego de las seis semanas del puerperio clasificó como diabetes mellitus tipo 2. CONCLUSIONES: luego de aplicada la intervención llegaron al término de la gestación más de la mitad de la muestra y disminuyó la morbimortalidad fetal.

BACKGROUND: tolerance to high levels of glucose is associated with fetal and mother morbidity and mortality, statistically similar to gestational diabetes. OBJECTIVE: to assess the results of the prophylactic use of insulin in patients with tolerance to high levels of glucose and bad obstetric antecedents. METHOD: an experimental design with the use of prophylactic insulin in pregnant women with tolerance to high levels of glucose with obstetric antecedents in the Ana Betancourt de Mora Ginecobstetric Teaching Hospital, Camagüey, from January 2009 to December 2010, was conducted. The universe was composed of 179 pregnant women and the non-probabilistic sample was composed of 25 patients. RESULTS: before the intervention 22 patients had no children, 16 of them were older than 30 years old and had no living children. As a family risk factor, diabetes mellitus type 2 represented the 56 %. All the patients presented two or more obstetric risks; habitual abortion and fetal deaths predominated. All the patients presented blood glucose levels higher than 4, 4 mmol/L when going to the catchment area; also, the results of their glucose tolerance tests were normal; maternal overweight represented the 44 %. After the insulin treatment was applied to the patients 20 pregnant women got to the term of pregnancy, there were two preterm deliveries, two abortions, and a stillbirth. There was not any neonatal death. After the six weeks of puerperium, one of the patients developed diabetes mellitus type 2. CONCLUSION: after the intervention was applied, more than the half of the sample got to the term of pregnancy and the fetal morbidity and mortality decreasedintervention studies.

Recognizing and treating anal cancer: training medical students and physicians in Puerto Rico.

OBJECTIVE: This training activity aimed at increasing the knowledge of anal cancer screening, diagnostic and treatment options in medical students and physicians, to determine the interest of these individuals in receiving training in the diagnosis and treatment of anal cancer, and to explore any previous training and/or experience with both anal cancer and clinical trials that these individuals might have. METHODS: An educational activity (1.5 contact hours) was attended by a group of medical students, residents and several faculty members, all from the Medical Sciences Campus of the University of Puerto Rico (n = 50). A demographic survey and a 6-item pre- and post-test on anal cancer were given to assess knowledge change. RESULTS: Thirty-four participants (68%) answered the survey. Mean age was 29.6 +/- 6.6 years; 78.8% had not received training in anal cancer screening, 93.9% reported being interested in receiving anal cancer training, and 75.8% expressed an interest in leading or conducting a clinical trial. A significant increase in the test scores was observed after the educational activity (pre-test: 3.4 +/- 1.2; post-test: 4.7 +/- 0.71). Three of the items showed an increase in knowledge by the time the post-test was taken. The first of these items assessed the participants' knowledge regarding the existence of any guidelines for the screening/treatment of patients with human papillomavirus (HPV)-related anal disease. The second of these items attempted to determine whether the participants recognized that anal intraepithelial neoplasia (AIN) 2 is considered to be a high-grade neoplasia. The last of the 3 items was aimed at ascertaining whether or not the participants were aware that warty growths in the anus are not necessarily a manifestation of high-grade AIN. CONCLUSION: This educational activity increased the participants' knowledge of anal cancer and revealed, as well, that most of the participants were interested in future training and in collaborating in a clinical trial. Training physicians from Puerto Rico on anal cancer clinical trials is essential to encourage recruitment of Hispanic patients in these studies now that the guidelines in anal cancer screening and treatment are on their way to be defined.

Misoprostol como método de interrupción del embarazo, una alternativa clínica económica / Misoprostol as a method of pregnancy interruption, a clinical and economical alternative

Fundamento: el aborto es la expulsión del producto de la concepción cuando todavía no es capaz de sobrevivir fuera del seno materno. Objetivo: comparar clínica y económicamente la efectividad del misoprostol como método de interrupción del embarazo con el método tradicional. Método: se realizó un estudio transversal descriptivo en el Hospital Universitario Manuel Piti Fajardo, Florida Camagüey, desde de enero hasta diciembre de 2010. El universo estuvo formado por 600 pacientes que acudieron a consulta de planificación familiar, la muestra quedó constituida por 450 embarazadas que cumplían los criterios de inclusión. Los datos fueron recogidos y procesados de forma computarizada, como medidas estadísticas números y por cientos. Resultados: el método se consideró efectivo ya que provocó el aborto completo sin requerir procedimiento quirúrgico. El aborto completo ocurrió en 409 pacientes, en el primer ciclo se presentaron 41 fallos, a 19 pacientes se les aplicó una segunda dosis y a las 22 restantes se les aplicó método quirúrgico, se logró mayor efectividad con el primer ciclo en 390 pacientes. Con la aplicación del método no quirúrgico existió un ahorro en el presupuesto de $16793.54. Conclusiones: los efectos secundarios más frecuentes después de aplicado el método fueron escalofríos, náuseas y dolores pélvicos, el mayor número de pacientes logró el aborto completo con la utilización del misoprostol vaginal en el primer ciclo donde fue poco representativo el número de fallos. Con la aplicación del método farmacológico existió un ahorro en el presupuesto de $16793.54 comparándolo con el aborto quirúrgico.

Background: abortion is the expulsion of a human fetus when it is not yet able to survive outside the womb. Objective: to compare clinical and economic effectiveness of misoprostol as a method of termination of pregnancy with the traditional method. Method: a descriptive, cross-sectional study was conducted at the University Hospital Manuel Piti Fajardo, Florida Camagüey, from January to December 2010. The universe was constituted by 600 patients who came to family planning consultation; the sample was made up 450 pregnants which met the inclusion criteria. Data were collected and processed in computerized form, as statistical measures, numbers and percents. Results: this method was considered effective because comprehensive abortion was achieved without requiring surgical procedure. Comprehensive abortion occurred at 409 patients, 41 failures were presented in the first cycle, 19 patients were applied a second dose and the 22 remaining surgical method was applied to them, the method was more effective with the first cycle in 390 patients. With the implementation of non-surgical method, there was a saving in the budget of $16793.54. Conclusions: the most common side effects after the use of this method were chills, nausea, and pelvic pain, the largest number of patients achieved comprehensive abortion with the use of vaginal misoprostol in the first cycle where the number of failures was unrepresentative. With the implementation of the pharmacological method, there was a saving in the budget compared to surgical abortion.

Cólera en Haití / Cholera in Haiti

La República de Haití con 9 millones de habitantes vive desde antaño una gran debilidad en varios frentes, pero en especial, en aspectos concernientes a la salud y a los servicios públicos que además de ser precarios solo alcanzan para una pequeña parte de la población. Terremotos, inundaciones y huracanes sumados a una eterna inestabilidad social y a una magra cobertura de salud llevan a panoramas ominosos como la actual epidemia de cólera del que solo se saldrá cuando se dejen de buscar culpables y se mancomunen el gobierno, ONGs y Naciones Unidas para controlar la epidemia y sentar bases sólidas de salubridad y protección social.

The Republic of Haiti, with 9 million inhabitants, has been living a great precariouness in several areas, specially in health and public services. These aspects are not only precarious but they can only reach a few people. Earthquakes, floods and hurricans added to a never ending social instability and a very poor health covering lead to ominous settings like the today colera epidemy. They will only get rid of this problem when they stop looking for guilty ones and the government start working together with ONG's and United Nations in order to control the epidemy and to stablish solid foundations of health and social protection.

In Corrientes (Argentina), from January 2004 to April 2005, fecal samples from under 5 years-old children with acute diarrhea were collected; the stool samples were cultured onto selective media, and those colonies suspected to be Salmonella, Vibrio, Aeromonas, Shigella, or Escherichia coli O157 were identified. The antimicrobial susceptibility was assessed by the disk diffusion method. Among 590 samples, the 7.7% were positive (Salmonella spp 32.6% and Shigella spp 67.4%). Of 31 Shigella isolates, 81% were S. flexneri, and 19% were S. sonnei. S. flexneri serotype 2 was the more frequent. S. flexneri strains showed higher multidrug resistance than S. sonnei strains. Among the Salmonella enterica serotypes, S. typhimurium and S. newport were the most frequent. Two isolates of Salmonella presented with multidrug resistance. This paper was a contribution to the knowledge of bacterial gastroenteritis etiology in our region and it called the attention to the emergence of multidrug-resistant enteropathogenic strains.

[Environmental impact of ecological changes in a subtropical area]. / Impacto ambiental de modificações ecológicas realizadas em uma área subtropical.

Infectious, clinical-surgical and environmental variables were studied in Ituzaingó and Posadas (Argentina) and differences were analyzed from 1994 to 2000, which corresponds to the building of the binational dam Yacyretá (Argentina-Paraguay) and to the resulting reservoir. The chosen infectious variables were diarrhea and respiratory infections and the clinical-surgical variables were cardiovascular diseases and polytraumas. Environmental variables were also investigated. Taking as a baseline the values corresponding to the year 1994, diarrhea in Ituzaingó, increased 6.5% during 1995 and 78.3% in 1996 returned to 1994 values. Posadas showed a rising tendency throughout the period investigated. In Ituzaingó, respiratory infectious rose 143% in 1995, and later returned to 1994 values. In Posadas they increased each year. Cardiovascular diseases reached 97.6% in Ituzaingó during 1995; lowered slightly in 1996 and reached 127% in the year 2000. The impact of the environmental variables was higher in Ituzaingó than Posadas. The negative impact of temperature related with the increased frequency of disease in Ituzaingó is more related to maximum temperature than with changes in humidity.

Impacto ambiental de modificações ecológicas realizadas em uma área subtropical / Environmental impact of ecological changes in a subtropical area

No período de 1994 a 2000, durante a construção e enchimento da represa Yacyretá, foram estudadas em Ituzaingó e Posadas variáveis infecciosas (diarréias e infecções respiratórias), clínico-cirúrgicas (doenças cardiovasculares e politraumatismos) e ambientais (pluviais, temperatura e umidade). As diarréias, em Ituzaingó, tiveram um aumento 6,5 por cento, 78,3 por cento e 13 por cento, respectivamente em 1995, 1996 e 1997 e nos anos seguintes os valores foram similares aos de 1994 e em Posadas mostraram uma tendência ascendente. As infecções respiratórias, em Ituzaingó em 1995, aumentaram 143 por cento e nos períodos subseqüentes voltaram aos limites de 1994 e, em Posadas tiveram valores ascendentes. No Hospital de Ituzaingó, em 1995, as doenças incrementaram 97,6 por cento, mostraram decréscimo em 1996 e atingiram 127 por cento em 2000; os politraumatismos aumentaram 107 por cento em 1995, declinaram 38 por cento em 1996 nos anos seguintes apresentaram tendência ascendente atingindo 33 por cento em 2000. O impacto das variáveis ambientais foi maior em Ituzaingó do que em Posadas. O aumento das doenças relacionou-se com a temperatura máxima, mas não com a umidade.

Infección por helicobacter pylori en niños del noreste argentino / Helicobacter pylori infection in children from northeast argentina: seroprevalence and its relation with the nutritional status and socio-sanitary conditions

No disponiéndose de datos sobre la infección por H. pylori en niños del nordeste argentino, se realizó un estudio seroepidemiológico a fin de conocer la prevalencia de este agente entre los menores de 14 años, evaluar si la infección impacta sobre el desarrollo de los niños y analizar la influencia de las variables socio-sanitarias sobre el riesgo de adquirir la infección. Se estudiaron 278 niños de ambos sexos de 4 a 14 años de edad (media=9 años), 158 de area rural y 120 de area urbana, residentes en 4 localidades del nordeste argentino con distintas condiciones sociales y ambientales. Se investigó anticuerpos IgG anti H. pylori y se evaluó el estado nutricional mediante la determinación de peso y talla, clasificandose a los niños en Eutróficos o Distróficos. De los 278 niños, 126 (45,3 por ciento) resultaron seropositivos para H. pylori, siendo 86 (68,3 por ciento) del area rural y 40 (31,7 por ciento) del area urbana, lo que señala un riesgo de infección mayor para los primeros. Las prevalencias encontradas en las cuatro localidades estudiadas fueron: Villa Olivari 50 por ciento, Albardones 59 por ciento, Villa Elisa 42 por ciento y el area céntrica de la ciudad de Resistencia 27 por ciento. La prevalencia de infección aumentó estadísticamente con la edad, no encontrandose diferencias significativas en relación con el género. Se observó una asociación significativa entre porcentaje de infección y el grado de instrucción de la madre, la carencia de cloacas en los domicilios y la falta de agua potable, no así con el grado de hacinamiento al dormir ni con el nivel de educación de los padres. No se encontró asociación significativa entre infección por H. pylori y distrofia entre los niños. Los altos índices de infección encontrados aún entre los niños con buenas condiciones sanitarias en sus hogares, inducen a la evaluación de otros factores favorecedores de la infección y a sugerir la necesidad de diseñar programas de educación comunitaria con la activa participación de las madres a fin de alertar sobre la infección por este agente y sus consecuencias
