Índice de massa corporal e desfechos clínicos: um estudo retrospectivo durante a pandemia de Covid-19 / Body mass index and clinical outcomes: a retrospective study in Covid-19 / Índice de masa corporal y resultado clínico: un estudio retrospectivo durante la pandemia de Covid-19

A COVID-19 é uma doença respiratória aguda provocada pela infecção do vírus SARS-CoV-2, que pode causar uma grave insuficiência respiratória hipoxêmica, complicações e mortes, principalmente na população com condições crônicas de saúde. Os mecanismos pelos quais a obesidade pode aumentar a gravidade da COVID-19 incluem mecanismos físicos, inflamação crônica e uma função imunológica prejudicada. Além disso, o índice de massa corporal elevado é um fator de risco para várias condições médicas que têm sido sugeridas para aumentar o risco de gravidade da COVID-19. Objetivo: analisar a associação entre o índice de massa corporal e desfechos clínicos dos casos confirmados de COVID-19. Metodologia: Estudo transversal, com coleta de dados de prontuários, conduzido de março de 2020 a dezembro 2021. Foram analisados os registros de prontuários, exames bioquímicos e de imagem de pacientes internados com COVID-19 em três hospitais da cidade de Francisco Beltrão (PR). As variáveis analisadas foram o diagnóstico nutricional, idade, sexo, necessidade de internação em UTI, comorbidades, dias de hospitalização, complicações, exames laboratoriais e desfecho. Os critérios para inclusão no estudo foram, pacientes hospitalizados com diagnóstico para COVID-19, com presença de diagnóstico nutricional relatado. Resultados: No ano de 2020 foram analisados 292 prontuários e no ano de 2021 foram 860 prontuários. Destes, somente 413 possuíam diagnóstico nutricional, sendo assim incluídos no presente estudo. Foram classificados como peso normal 78 (18,9%), com sobrepeso 153 (37%)e como obeso 182 (44,1%) participantes. A maior prevalência de obesidade foi encontrada no sexo feminino (52,5%), portadores de diabetes (27,6%), pacientes com estado geral comprometido (67,9%), que apresentaram complicações pulmonares (54,5%) e arritmias (23%). A média de idade encontrada em pacientes com obesidade foi mais jovem (55,54) em comparação com os classificados com sobrepeso (59,08) e normal (62,51). Observou-se que quanto maior o IMC menor foram os valores encontrados para idade (rho = -0,190), leucócitos (rho = -0,109), ureia (rho = -0,145) e D-dímero (rho = -0,155). Conclusão: Este estudo fornece evidências de que o sobrepeso e/ou obesidade então associadas a um pior quadro clínico durante a internação dos pacientes com COVID-19. Em relação a frequência de óbito, não houve diferença estatística em relação ao diagnóstico nutricional.

COVID-19 is an acute respiratory disease caused by SARS-CoV-2 virus infection, which can cause severe hypoxemic respiratory failure, complications, and deaths, especially in the population with chronic health conditions. The mechanisms by which obesity may increase the severity of COVID-19 include physical mechanisms, chronic inflammation, and impaired immune function. In addition, high body mass index is a risk factor for several medical conditions that have been suggested to increase the risk of COVID-19 severity. Objective: to analyze the association between body mass index and clinical outcomes of confirmed cases of COVID-19. Methodology: Cross-sectional study, with data collection from medical records, conducted from March 2020 to December 2021. The records of medical records, biochemical and imaging tests of patients hospitalized with COVID-19 in three hospitals in the city of Francisco Beltrão (PR) were analyzed. The variables analyzed were nutritional diagnosis, age, gender, need for ICU admission, comorbidities, days of hospitalization, complications, laboratory tests and outcome. The inclusion criteria for the study were, hospitalized patients with diagnosis for COVID-19, with presence of nutritional diagnosis reported. Results: In the year 2020, 292 medical records were analyzed and in the year 2021 there were 860 medical records. Of these, only 413 had nutritional diagnosis, thus being included in this study. Were classified as normal weight 78 (18.9%), overweight 153 (37%), and obese 182 (44.1%) participants. The highest prevalence of obesity was found in females (52.5%), patients with diabetes (27.6%), patients with impaired general condition (67.9%), who presented pulmonary complications (54.5%) and arrhythmias (23%). The mean age found in obese patients was younger (55.54) compared to those classified as overweight (59.08) and normal (62.51). It was observed that the higher the BMI the lower were the values found for age (rho = -0.190), leukocytes (rho = -0.109), urea (rho = -0.145) and D-dimer (rho = -0.155). Conclusion: This study provides evidence that overweight and/or obesity then associated with a worse clinical picture during hospitalization of patients with COVID-19. Regarding the frequency of death, there was no statistical difference in relation to nutritional diagnosis.

De ellos, sólo 413 tenían diagnóstico nutricional, por lo que fueron incluidos en el presente estudio. 78 (18,9%) participantes fueron clasificados como normopeso, 153 (37%) como sobrepeso y 182 (44,1%) como obesidad. La mayor prevalencia de obesidad se encontró en el sexo femenino (52,5%), pacientes con diabetes (27,6%), pacientes con estado general comprometido (67,9%), quienes presentaron complicaciones pulmonares (54,5%) y arritmias (23%). La edad promedio encontrada en los pacientes con obesidad fue menor (55,54) en comparación con los clasificados como con sobrepeso (59,08) y normales (62,51). Se observó que a mayor IMC, menores son los valores encontrados para edad (rho = -0,190), leucocitos (rho = -0,109), urea (rho = -0,145) y dímero D (rho = -0,155). Conclusión: Este estudio proporciona evidencia de que el sobrepeso y/u obesidad se asocia con una peor condición clínica durante la hospitalización de pacientes con COVID-19. En cuanto a la frecuencia de muerte, no hubo diferencia estadística en relación al diagnóstico nutricional.

Sociodemographic, behavioral, obstetric, and healthcare factors associated with low weight at birth: a case-control study

ABSTRACT BACKGROUND: Understanding social determinants is crucial for implementing preventive strategies, especially for low birth weight (LBW)—a public health issue that severely increases the risk of morbimortality in children. OBJECTIVE: This study aimed to identify the factors associated with LBW among newborns, assisted by the Brazilian Unified Health System. DESIGN AND SETTING: It analyzed data from newborns and their mothers. The sample was selected by convenience from users of the public health system in Francisco Beltrão (Paraná, Brazil). METHODS: Cases (n = 26) were babies weighing ≤ 2,500 g and controls (n = 52) > 2,500 g. All babies were assessed and paired by sex and date of birth in a 1:2 proportion. Statistical power was computed a posteriori, revealing a power of 87% (α = 0.05). RESULTS: Strong and significant differences were found in the bivariate analysis, in which the number of current smokers or those who quit during pregnancy was higher among mothers of babies with LBW. Moreover, the gestational weeks were lower among these cases. Logistic regression models indicated that the gestational week (odds ratio [OR] = 0.17, 95% confidence interval [CI]:0.05-0.54) and fathers' educational level (high school or above; OR = 0.22, 95% CI:0.06-0.99) were related to lower chances of low birth weight. CONCLUSIONS: Our findings confirm previous investigations on LBW's multi-causality, showing that the gestational week could reduce up to 82% chances of a baby being born with ≤ 2,500 g. Its association with paternal education underlines the importance of comprehensive policies to protect newborns.

Evaluation of oxidative stress level: reactive oxygen species, reduced glutathione, and D-dimer in patients hospitalized due to COVID-19.

Elevated D-dimer levels at hospital admission may also indicate a higher likelihood of progressing to a severe or critical state. This study aimed to assess reactive oxygen species (ROS), non-enzymatic antioxidant reduced glutathione (GSH), and D-dimer levels in COVID-19 patients upon admission, examining their association with mortality outcomes. Data was collected from the medical records of 170 patients hospitalized in a referral hospital unit between March 2020 and December 2021. Patients were divided into two groups: the ward bed group (n = 87), comprising 51% with moderate clinical conditions, and the intensive care unit (ICU) group (n = 83), comprising 49% with severe conditions. The mean age was 59.4 years, with a male predominance of 52.4%. The overall death rate was 43%, with 30.6% in the moderate group and 69.4% in the severe group. The average time from symptom onset to hospitalization was 6.42 days. Results showed that non-survivors had high D-dimer and ROS counts, longer ICU stays, and worse saturation levels at admission. In conclusion, elevated ROS and D-dimer levels may contribute to worse outcomes in critically ill patients, potentially serving as specific and sensitive predictors of poor outcomes upon admission.

Latent Tuberculosis Infection Diagnosis Using QuantiFERON-TB Gold Plus Kit Among Correctional Workers: A Cross-Sectional Study in Francisco Beltrão-PR, Brazil.

Correctional workers form a high-priority group for tuberculosis control measures because of their high exposure and risk. This cross-sectional study conducted in April and May 2022 included 71 criminal police officers from the State Penitentiary of Francisco Beltrão-PR, Brazil. Their sociodemographic and laboratory data were collected. Latent tuberculosis infection (LTBI) was assessed using a QuantiFERON-TB Gold Plus in-tube test kit. Binary logistic regression was applied to calculate the odds ratios (ORs) and 95% confidence intervals (CI) of the LTBI predictors. The prevalence of LTBI was 22.6% (95% CI, 12.8-32.2%). Factors associated with LTBI were age > 43 years (OR, 0.18; 95% CI, 0.04-0.70; p < 0.014) and the use of medications (OR, 5.13; 95% CI, 1.40-18.87; p < 0.014). The prevalence was close to that estimated worldwide for LTBI in correctional workers, reinforcing the need for occupational health control measures consisting of regular screening and treatment of positive cases of latent infection among correctional workers to reduce the risk of illness and spread of infection in the penitentiary system and community.

Working Conditions and Health of Prison Officers in Paraná (Brazil).

OBJECTIVES: This cross-sectional study was carried out to identify the associations between working and health conditions among prison officers at a state prison in Paraná, Brazil. MATERIAL AND METHOD: A proportional and stratified random sample of 125 individuals was used. The participants, who were not identified, completed a self-administered questionnaire. RESULTS: The results showed a prevalence of minor psychiatric disorders (MPD) of 30.4% (95%CI: 22.4-39.2). A total of 17.9% of the respondents had persistent stress (95%CI: 12.2-25.2), 66.4 had up to five health-related complaints (95%CI: 58.4-75.2) and 9.6% had scores that indicated higher risk for alcohol abuse and/or dependance (95%CI:4.8-16.0). Multivariate analyses showed that with an MPD outcome, health problems (p<0.01), physical environment (p=0.013) and organizational risks (p<0.01) were significant predictors. Persistent stress was predicted by age (p=0.031), health problems (p<0.01) and organizational risks (p=0.023), while health complaints were associated with health problems (p<0.01) and physical environment (p<0.01). There were no significant predictors for higher risk for alcohol abuse and/or dependance. DISCUSSION: In general, the results demonstrate the precarious nature of the work of prison officers, and reveal the importance of further studies to evaluate whether this is a specific reality of the unit that was investigated, or whether these results are common in other prison environments.

Prevalence of HPV and associated factors in a population of women living in southern Brazil.

OBJECTIVE: To determine the prevalence of HPV and investigate factors associated with the infection in women in the city of Francisco Beltrão, southwest Paraná, attending the public health system. METHODS: This cross-sectional study included 324 women, aged between 18 and 65 years, who were attending public health services for routine gynecological consultation. Interviews were conducted to obtain information about socioeconomic, sexual, gynecological, and life habits. After performing the Papanicolaou test, endocervical brush was employed to detect HPV by polymerase chain reaction with the primers MY09-MY11. RESULTS: The prevalence of HPV was 6.8%, out of which 58.3% presented with cytopathologic alterations. And the presence of current cervical alterations can increase the chances of having HPV by almost 33 times (ORadj: 32.688; p < 0.001), recent vaginal infection increased the chances of HPV infection by 2.7 times (ORadj: 2.773; p = 0.04). The non-white ethnicity increased HPV infection chances threefold (ORadj: 3.058; p = 0.039). CONCLUSION: The main finding was low prevalence of HPV infection. Factors that may be linked to HPV infection were cervical alterations, recent vaginal infection, and women's ethnicity.

University Students' Knowledge about the Relation between Human Papillomavirus (HPV) and Head and Neck and Oral Cancers.

INTRODUCTION: Human papillomavirus (HPV) causes the most common sexually transmitted infection (STI) in the world. It affects people regardless of gender and age, causing genital warts and cancer. OBJECTIVE: To evaluate university students' knowledge of HPV and its relationship with head and neck and oral cancers. METHODS: This is a cross-sectional study using an online questionnaire administered to undergraduate students at a public university (n=335). RESULTS: In total, 69.3% of the participants were unaware of the relationship between HPV and head and neck cancers and 34.6% claimed that HPV may not cause oral cancer.  The chances of knowing about the relationship of HPV with head and neck cancers were significant for participants who knew that HPV could be asymptomatic (OR = 9.9; p = 0.029), that might cause genital warts in men (OR = 4.0; p = 0.015), and those aged 24 years or older (OR = 1.9; p = 0.021). However, undergraduate students in the field of health and medicine (OR = 0.419; p = 0.002), who had sex at least twice a week (OR = 0.471; p = 0.017), and were unaware of the target public for the HPV vaccine (OR: 0.222, p<0.001) were less likely to know about the relationship. Students who knew of the relationship between HPV and female (OR = 3.6; p = 0.010) and male genital warts (OR = 3.0; p = 0.005) or were immunized (OR = 1.8; p = 0.020) were more likely to understand the viral interaction with oral cancer. Those who were unaware of the population eligible for HPV vaccine (OR = 0.493; p = 0.017) also showed gaps in their knowledge of this relationship. CONCLUSION: Our findings showed that there were limitations in the knowledge about HPV, its vaccine, and its relationship with head and neck and oral cancers.

Prevalence and factors associated to cervical changes in units from the Single Health System.

OBJECTIVE: To estimate the prevalence and risk factors associated with cytopathological changes in the uterine cervix of women treated by the Unified Health System. METHOD: This is a cross-sectional study carried out with 350 women, between 14 and 79 years old who underwent pap smear tests in heath units in Francisco Beltrão, Paraná. Cervical cytopathological analyses and a questionnaire were applied to obtain socioeconomic information, as well as data on sexual behavior, gynecological aspects, and life habits. Chi-square test and logistic regression with p <0.05 were applied for statistical analysis. RESULTS: The prevalence of cervical changes was 3.4% and the main categories found were low-grade cervical intraepithelial lesion, high-grade cervical intraepithelial lesion, and atypical cells of undetermined significance. From these, the first were present in 16.6% of women under 25 years old. The multivariate analysis pointed at associations between previous results of the cytopathology test (OR = 25.693), smoking (OR = 7.576), and oral contraceptives (OR = 5.265) and the outcome. CONCLUSION: Women with a history of previous cervical cytopathological abnormality, use of oral contraceptives, and smokers were more likely to have an abnormal result in the pap smear test.

Dexamethasone for treating SARS-CoV-2 infection: a systematic review and meta-analysis

ABSTRACT BACKGROUND: Considering the disruptions imposed by lockdowns and social distancing recommendations, coupled with overwhelmed healthcare systems, researchers worldwide have been exploring drug repositioning strategies for treating severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). OBJECTIVE: To compile results from randomized clinical trials on the effect of dexamethasone, compared with standard treatment for management of SARS-CoV-2. DESIGN AND SETTING: We conducted a systematic review and meta-analysis in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines in a Brazilian public university. METHODS: We sought to compile data from 6724 hospitalized patients with confirmed or suspected SARS-CoV-2 infection. RESULTS: Treatment with dexamethasone significantly reduced mortality within 28 days (risk ratio, RR: 0.89; 95% confidence interval, CI: 0.82-0.97). Dexamethasone use was linked with being discharged alive within 28 days (odds ratio, OR: 1.20; 95% CI: 1.07-1.33). CONCLUSIONS: This study suggests that dexamethasone may significantly improve the outcome among hospitalized patients with SARS-CoV-2 infection and associated severe respiratory complications. ­Further studies need to consider both dose-dependent administration and outcomes in early and later stages of the disease.

Sleep quality and common mental disorder in the hospital Nursing team.

OBJECTIVE: to determine the prevalence of sleep quality and common mental disorder in Nursing professionals and factors associated with sleep change. METHOD: a cross-sectional, analytical and quantitative study developed with 196 Nursing professionals of a public hospital and a mixed one. Data was collected by means of an instrument of sociodemographic characterization, by the Self-Report Questionnaire 20 and Pittsburgh Sleep Quality Index and were analyzed by descriptive and inferential statistics to identify possible factors associated with sleep changes. RESULTS: sleep changes were identified among the Nursing professionals with a frequency of 76.5% (70.4-82.1). Sleep quality was classified as poor in 41.8% (41.8-55.6) and sleep disorder in 27.6%. (21.4-34.2). The prevalence of common mental disorder was identified in 36.7% (30.1-43.9). The main factor for poor sleep quality was the presence of common mental disorder (Odds Ratio: 5.15; p<0.001). CONCLUSION: sleep changes were prevalent and the characteristics of the work environment and the presence of mental disorder showed relevance in the changes.

Sociodemographic, behavioral, and geriatric characteristics in older adults with and without HIV: A case-control study.

ABSTRACT: Older adults with human immunodeficiency virus (HIV) have higher risks for early manifestations of age-related disabilities. The objective of this study was to compare HIV-positive and HIV-negative adults aged ≥50 years in relation to sociodemographic, behavioral, and geriatric characteristics. A case-control study was conducted with a >90% estimated statistical power. A total of 52 individuals living with HIV were matched by age, sex, and neighborhood of residence with 104 community controls. Age-related disabilities were assessed throughout a comprehensive geriatric assessment. Review of medical records and interviews were used to obtain behavioral and clinical covariates. No statistical differences on clinically significant age-related disabilities were found. However, multivariate regression analyses, controlling for education and income, revealed that behavioral (use of condom [odds ratio {OR}: 7.03; 95% confidence intervals {CI}: 2.80-7.65] and number of medical visits [OR: 1.25; 95%CI: 1.09-1.43]), along with faster gait speed (OR: 17.68; 95%CI: 2.55-122.85) and lower body and muscle mass indexes were independently associated with HIV (OR: .88; 95%CI: .79-.98 and OR: .72; 95%CI: .54-.97, respectively). In summary, results on age-related disabilities between groups could mean that public policies on HIV might be contributing to patients' positive outcomes regardless of the effects of aging, albeit gait speed, body and muscle mass indexes were independently associated with HIV. Screenings for age-related disabilities in specialized HIV services are recommended.

Burnout Syndrome in Brazilian Medical Doctors: A Cross-Sectional Examination of Risk and Protective Factors.

Objectives: This investigation sought to identify the prevalence of Burnout Syndrome (BS) among Brazilian medical doctors (BS) and the associations with risk factors and protective factors. Methods: Out of 206 registered MD from a medium-sized municipality, 121 were enrolled in this cross-sectional study. Convenience sampling was used. Based on Cohen's f 2, a power of 98% and a 0.05 alpha was achieved. MD responded to sociodemographic questions and to the Portuguese-version of the Maslach Burnout Inventory-Human Services Survey (MBI). Risk and protective factors linked with BS were examined with regression analyses. Results: The age of the participants ranged from 25 to 69 years (M = 40.89; SD = 10.13) and 73.6% were male. The prevalence of BS was 7.5%. Differential aspects were related to BS. For instance, while not reporting satisfaction with the institution (ß = 16.16, p < 0.001) and not practicing physical exercise (ß = 7.39, p = 0.014) were associated with higher scores in the BS composite score, those who did not intend to change their careers (ß = -17.15, p < 0.001) and participants who saw mental health specialists (ß = -8.99, p = 0.007) scored lower, accounting for nearly a half of the BS composite score (R 2 = 46%). Conclusion: The prevalence of BS in this study falls within the range previously reported among healthcare professionals (i.e., 2.6-11.8%). Moreover, data suggested that commitment with the occupation and with the participant's own mental health could boost reactions against the deleterious effects of the BS. In this sense, organizations can develop strategies for preventing BS, a process that is known to be chronic and, to some extent, preventable.

COVID-19: The question of genetic diversity and therapeutic intervention approaches.

Coronavirus disease 2019 (COVID-19), caused by the Severe Acute Respiratory Syndrome Coronavirus type 2 (SARS-CoV-2), is the largest pandemic in modern history with very high infection rates and considerable mortality. The disease, which emerged in China's Wuhan province, had its first reported case on December 29, 2019, and spread rapidly worldwide. On March 11, 2020, the World Health Organization (WHO) declared the COVID-19 outbreak a pandemic and global health emergency. Since the outbreak, efforts to develop COVID-19 vaccines, engineer new drugs, and evaluate existing ones for drug repurposing have been intensively undertaken to find ways to control this pandemic. COVID-19 therapeutic strategies aim to impair molecular pathways involved in the virus entrance and replication or interfere in the patients' overreaction and immunopathology. Moreover, nanotechnology could be an approach to boost the activity of new drugs. Several COVID-19 vaccine candidates have received emergency-use or full authorization in one or more countries, and others are being developed and tested. This review assesses the different strategies currently proposed to control COVID-19 and the issues or limitations imposed on some approaches by the human and viral genetic variability.

A qualidade do sono foi classificada como ruim em 41,8% (41,8-55,6) e o distúrbio do sono em 27,6% (21,4-34,2). Identificou-se uma prevalência de transtorno mental comum em 36,7% (30,1-43,9). O principal fator para a má qualidade do sono foi a presença de transtorno mental comum (Odds ratio: 5,15 p<0,001). Conclusão: as alterações de sono foram prevalentes e as características do ambiente de trabalho e a presença de transtorno mental comum apresentaram relevância com as alterações.

Nutritional response and clinical complications in patients with post-pyloric and gastric enteral tubes / Resposta nutricional e complicações clínicas em pacientes com uso de sonda gástrica ou pós-pilórica

ABSTRACT Objective The present study assessed the differences in nutritional markers (albumin, transferrin, total body fat, and body mass index) and clinical complications (diarrhea, vomiting, and diet interruptions) associated with enteral nutrition. Methods This is an open-label, randomized, two-arm parallel-group controlled clinical trial. Out of 105 patients assessed for eligibility, 35 adult patients were randomly divided into two groups and followed for 28 days. The sample comprised a heterogeneous group of severely ill individuals initially treated in the intensive care units. Neurological conditions (i.e., strokes and brain tumours) were the most common reasons for hospitalization. Patients had one singularity: the clinical need for exclusive enteral nutrition therapy. One group received the diet via gastric tube and the other via a post-pyloric tube. Results The groups presented increases in the calories prescribed and administered, as well as reduced diet discontinuation. Although similar values were observed up to day 21, the post-pyloric group showed increased albumin levels compared to the gastric group on Day 28. Transferrin levels increased over time in both groups. Conclusion There were no differences in the complications recorded between groups, albeit serum albumin significantly increased in the post-pyloric group.

RESUMO Objetivo Avaliar diferenças tanto nos marcadores nutricionais (albumina, transferrina, gordura corporal e índice de massa corporal) quanto nas complicações clínicas (diarreia, vômitos e interrupções na dieta) associadas à nutrição enteral administrada através de duas vias tradicionais. Métodos Este é um ensaio clínico de tratamento, paralelo de dois braços, aberto e randomizado controlado. Dos 105 participantes avaliados para elegibilidade, 35 pacientes adultos foram divididos aleatoriamente em dois grupos e seguidos por 28 dias. A amostra foi formada por um grupo heterogêneo e gravemente enfermo, tratados inicialmente em unidades de terapia intensiva. Condições neurológicas, como acidente vascular e tumores cerebrais foram as razões principais para hospitalização. Os pacientes tinham em comum um aspecto, a saber, a necessidade clínica exclusiva de receber nutrição enteral. Um grupo recebeu a dieta via sonda gástrica e o outro através de sonda pós-pilórica. Resultados Os grupos apresentaram aumento de calorias prescritas e administradas, bem como redução da descontinuação da dieta. Embora valores semelhantes tenham sido observados até o 21° dia, o grupo pós-pilórico apresentou aumento dos níveis de albumina em relação ao grupo gástrico no dia 28. Os níveis de transferrina aumentaram ao longo do tempo em ambos os grupos. Conclusão Não houve diferenças nas complicações registradas entre os grupos, embora níveis séricos de albumina aumentaram significativamente no grupo pós-pilórico.

Prevalence and factors associated to cervical changes in units from the Single Health System / Prevalencia y factores asociados a las alteraciones cervicales en unidades del Sistema Único de Salud / Prevalência e fatores associados às alterações cervicais em unidades do Sistema Único de Saúde

ABSTRACT Objective: To estimate the prevalence and risk factors associated with cytopathological changes in the uterine cervix of women treated by the Unified Health System. Method: This is a cross-sectional study carried out with 350 women, between 14 and 79 years old who underwent pap smear tests in heath units in Francisco Beltrão, Paraná. Cervical cytopathological analyses and a questionnaire were applied to obtain socioeconomic information, as well as data on sexual behavior, gynecological aspects, and life habits. Chi-square test and logistic regression with p <0.05 were applied for statistical analysis. Results: The prevalence of cervical changes was 3.4% and the main categories found were low-grade cervical intraepithelial lesion, high-grade cervical intraepithelial lesion, and atypical cells of undetermined significance. From these, the first were present in 16.6% of women under 25 years old. The multivariate analysis pointed at associations between previous results of the cytopathology test (OR = 25.693), smoking (OR = 7.576), and oral contraceptives (OR = 5.265) and the outcome. Conclusion: Women with a history of previous cervical cytopathological abnormality, use of oral contraceptives, and smokers were more likely to have an abnormal result in the pap smear test.

RESUMEN Objetivo: estimar la prevalencia y los factores de riesgo asociados con las alteraciones citopatológicas en cuello uterino de mujeres atendidas por el Sistema Único de Salud. Método: Estudio transversal realizado con 350 mujeres, entre 14 y 79 años, que se sometieron a una prueba de Papanicolaou en unidades de salud de Francisco Beltrão, Paraná. Se realizó análisis citopatológicos cervicales y se aplicó un cuestionario para obtener informaciones socioeconómicas, ginecológicas, sobre conducta sexual y hábitos de vida. La prueba de chi-cuadrado y la regresión logística con p <0.05 fueron aplicadas para el análisis estadístico. Resultados: La prevalencia de alteraciones cervicales fue del 3,4% y las principales categorías encontradas fueron lesión intraepitelial de bajo grado, lesión intraepitelial de alto grado y atipias de significado indeterminado. De estos, el primero estuvo presente en el 16,6% de las mujeres menores de 25 años. El análisis multivariante señaló asociaciones entre el resultado citopatológico previo (OR = 25.693), el tabaquismo (OR = 7.576) y el consumo de anticonceptivos (OR = 5.265) con el resultado. Conclusión: Las mujeres con antecedentes de alteraciones cervicales previas, uso de anticonceptivos orales, y fumadoras tienen más probabilidades de alterar el cuello uterino.
