HPV vaccine narratives on Twitter during the COVID-19 pandemic: a social network, thematic, and sentiment analysis.

INTRODUCTION: The COVID-19 pandemic has increased online interactions and the spread of misinformation. Some researchers anticipate benefits stemming from improved public awareness of the value of vaccines while others worry concerns around vaccine development and public health mandates may have damaged public trust. There is a need to understand whether the COVID-19 pandemic, vaccine development, and vaccine mandates have influenced HPV vaccine attitudes and sentiments to inform health communication strategies. METHODS: We collected 596,987 global English-language tweets from January 2019-May 2021 using Twitter's Academic Research Product track. We determined vaccine confident and hesitant networks discussing HPV immunization using social network analysis. Then, we used a neural network approach to natural language processing to measure narratives and sentiment pertaining to HPV immunization. RESULTS: Most of the tweets in the vaccine hesitant network were negative in tone (54.9%) and focused on safety concerns surrounding the HPV vaccine while most of the tweets in the vaccine confident network were neutral (51.6%) and emphasized the health benefits of vaccination. Growth in negative sentiment among the vaccine hesitant network corresponded with legislative efforts in the State of New York to mandate HPV vaccination for public school students in 2019 and the WHO declaration of COVID-19 as a Global Health Emergency in 2020. In the vaccine confident network, the number of tweets concerning the HPV vaccine decreased during the COVID-19 pandemic but in both vaccine hesitant and confident networks, the sentiments, and themes of tweets about HPV vaccine were unchanged. CONCLUSIONS: Although we did not observe a difference in narratives or sentiments surrounding the HPV vaccine during the COVID-19 pandemic, we observed a decreased focus on the HPV vaccine among vaccine confident groups. As routine vaccine catch-up programs restart, there is a need to invest in health communication online to raise awareness about the benefits and safety of the HPV vaccine.

Investigating the early impacts of the COVID-19 pandemic on modifiable risk factors for cancer and chronic disease: a repeated cross-sectional study in Alberta, Canada.

OBJECTIVES: This study contributes to empirical evidence by examining the impact of the first and second waves of the COVID-19 pandemic on modifiable risk factors (MRF) and whether these patterns differ according to level of material deprivation among people living in Alberta. METHODS: Using data from a repeated cross-sectional provincial health survey (Alberta Community Health Survey (ACHS): 2018-2021), we conducted logistic regression analyses examining the impacts of the COVID-19 pandemic on meeting national guidelines on four MRFs (tobacco use, physical activity, fruit and vegetable consumption, alcohol use) (n=11,249). We compared population-level changes in MRFs from one year before the COVID-19 pandemic (March 2019-February 2020) to one year during the pandemic (March 2020-February 2021) in Alberta. We also assessed whether these trends differed by a measure of material deprivation. RESULTS: Compared to the pre-COVID-19 period, the fully adjusted odds of meeting recommended guidelines for fruit and vegetable consumption (OR=0.42) decreased during the pandemic. Individuals experiencing high material deprivation had lower odds of meeting recommended guidelines for physical activity (OR=0.65) and higher odds of not being current tobacco users (OR=1.36) during the pandemic versus during the pre-pandemic period. CONCLUSION: At a population level, analyses from the ACHS showed minimal impacts of the first year of the COVID-19 pandemic on MRFs, besides fruit and vegetable consumption. Yet, stratifying results showed statistically significant differences in pandemic impacts on MRFs by level of material deprivation. Therefore, understanding the influence of material deprivation on MRFs during the pandemic is key to tailoring future public health interventions promoting health and preventing cancer and chronic disease.

RéSUMé: OBJECTIFS: Notre étude contribue aux preuves empiriques en examinant l'impact de la première et de la deuxième vague de la pandémie de COVID-19 sur les facteurs de risque modifiables (FRM) et en déterminant si ces tendances diffèrent selon le niveau de défavorisation matérielle chez les personnes vivant en Alberta. MéTHODE: À l'aide des données d'une enquête de santé transversale provinciale répétée (Alberta Community Health Survey [ACHS] : 2018-2021), nous avons mené des analyses de régression logistique pour étudier les impacts de la pandémie de COVID-19 sur le respect des directives nationales pour quatre FRM (tabagisme, activité physique, consommation de fruits et légumes, consommation d'alcool) (n = 11 249). Nous avons comparé les changements populationnels dans les FRM une année avant la pandémie de COVID-19 (mars 2019 à février 2020) et une année durant la pandémie (mars 2020 à février 2021) en Alberta. Nous avons aussi cherché à déterminer si ces tendances différaient selon un indicateur de défavorisation matérielle. RéSULTATS: Comparativement à la période ayant précédé la COVID-19, le rapport de cotes entièrement ajusté pour le respect des directives de consommation de fruits et légumes recommandées (RC = 0,42) a diminué durant la pandémie. Les personnes aux prises avec une importante défavorisation matérielle ont présenté une probabilité plus faible de respecter les directives recommandées pour l'activité physique (RC = 0,65) et une probabilité accrue de ne pas être des consommateurs actuels de produits du tabac (OR = 1,36) durant la pandémie qu'avant la pandémie. CONCLUSION: Pour l'ensemble de la population, nos analyses de l'ACHS montrent que la première année de la pandémie de COVID-19 a eu très peu d'impact sur les FRM, sauf pour la consommation de fruits et légumes. Pourtant, la stratification des résultats montre des écarts significatifs dans les impacts de la pandémie sur les FRM selon le niveau de défavorisation matérielle. Il est donc essentiel de comprendre l'influence de la défavorisation matérielle sur les FRM durant la pandémie pour adapter les futures interventions de promotion de la santé et de prévention du cancer et des maladies chroniques.
