Objetivos: O suicídio é considerado um grave problema de saúde pública, atingindo especialmente estudantes de medicina, que apresentam alta prevalência de ideação suicida, de aproximadamente 11,1%. Este estudo tem como objetivo avaliar o risco de suicídio em acadêmicos de medicina de uma Instituição de Ensino Superior do interior do estado de São Paulo. Métodos: Trata-se de estudo transversal realizado em 169 estudantes de medicina da I, II, III e V etapas. Foram aplicados dois questionários: o módulo C do Mini Internacional Neuropsychiatric Interview (MINI), a partir do qual o risco de suicídio foi classificado como "baixo" ou "moderado/alto"; e outro questionário com 23 questões referentes a fatores clínicos e demográficos potencialmente associados ao risco de suicídio. Uma análise exploratória preliminar foi feita para investigar essa associação, seguida de uma regressão logística utilizada para realizar uma análise multivariada. Resultados: Dos entrevistados que responderam ao MINI, 131 (77,5%) apresentaram baixo risco de suicídio e 37 (21,9%), risco moderado/alto. As variáveis que apresentaram associação com o risco de suicídio foram: histórico de suicídio na família (RR= 5,90; p= 0,001) e diagnóstico de transtornos mentais (RR= 3,96; p= 0,004). O consumo de álcool apresentou associação com risco de suicídio na análise preliminar bivariada (RR= 4; p= 0,046), porém esta associação não permaneceu significativa no modelo final da análise multivariada (RR= 3,54; p= 0,059). Conclusão: Os resultados evidenciaram que histórico de suicídio na família e o diagnóstico de transtornos mentais foram associados ao risco de suicídio e podem ser utilizados para a identificação dos alunos em risco e para guiar estratégias preventivas nas Instituições de Ensino Superior.

BACKGROUND: Hesitation and refusal to take a second dose of the vaccine for coronavirus disease 19 (COVID-19) are prevalent. OBJECTIVES: We aimed to identify predictive factors for hesitation or refusal and describe groups with higher rates of vaccine hesitancy. DESIGN AND SETTING: A cross-sectional study in Assis City, Brazil. METHODS: The study included adults who passed the due date for taking the COVID-19 second dose vaccine. Participants were recruited in December 2021 using a mobile-based text message. Sociodemographic and clinical data and reasons for hesitance were collected. The outcome was the attitude towards completing the recommended second dose of the vaccine. Bivariate and multivariate Poisson analyses were performed to determine the adjusted predictors. RESULTS: Participants between 30-44 years of age had a 2.41 times higher prevalence of hesitation than those aged 18-29 years. In addition, people who had adverse events or previously had COVID-19 had 4.7 and 5.4 times higher prevalences of hesitation, respectively (P value < 0.05). CONCLUSION: We found a significant group of adults aged between 30-44 years who refused the second dose of the COVID-19 vaccine. Furthermore, those who reported adverse effects after the first dose and those who had COVID-19 previously were a significant group for refusal.

Background: Limited research has examined mobile phone-based platforms for survey recruitment, especially during the COVID-19 pandemic in Brazil. Our objective was to investigate the feasibility and representativeness of mobile phone-based advertisement during a preliminary study about COVID-19 vaccine hesitation in Brazil. Moreover, we evaluate whether the older population can be reached through mobile phone-based platforms of the survey. Methods: We conducted a study in December 2021 based on a preliminary survey about the COVID-19 vaccine hesitation in Assis, Brazil, Sao Paulo state. From a list of the adult population hesitant for the second dose of the COVID-19 vaccine, we sent a mobile phone-based advertisement inviting the participants to answer the survey for one week. The respondent's data were collected in a Google form platform. The comparison between the target population and the respondents was made using the Chi-squared test and the Welch's test, using a P-value of .05 as significative. Results: The response rate was 9.99% after one week. The mean age of the respondent group was 33.97 (SD 14.99) and 35.05 (SD 14.19) of the population, with a P-value of .192 and a Cohen's d coefficient of 0.0754, corresponding to a small effect size between groups. We demonstrate that the mobile phone-based survey is a feasible and representative strategy during the pandemics in Brazil. Moreover, the older population respondent was representative. Conclusion: We achieved a representative sample of respondents using the mobile phone-based survey in Brazil. Furthermore, it was representative in all sociodemographic and health characteristics assessed. Finally, these findings suggest the method is a highly feasible and economical means of recruiting for survey research.
