Geriatric oral health neglect: calculus on the attached gingiva: a case report.

Introduction and importance: Aging exerts various effects on and causes changes to the oral tissues. It is often difficult to distinguish between what is caused by the physiological process of aging itself and what is caused by the individual's lifestyle or diseases. The elderly face peculiar health challenges and require special dental care. It is therefore vital that greater attention be given to the oral health needs of this rapidly population. In this article, the authors present the case of an elderly female patient with a rare case of calculus on the attached gingiva. Case presentation: A 90-year-old retired teacher with a history of hypertension, presented with a small, painless, grayish-brown growth on her attached gingiva, noticed by her daughter-in-law. Examination revealed signs of gingivitis and significant dental issues including missing teeth, fractures, and calculus buildup. Diagnosis of chronic generalized marginal gingivitis and calculus deposition was made, and scaling and polishing were performed. Perforation of the attached gingiva was observed during scaling thus exposing the root, which facilitated the calculus accumulation. Post-procedure care included medication and oral hygiene instructions. Follow-up after 1 week showed satisfactory healing, but subsequent assessment at 3 months revealed plaque accumulation, with the patient declining further treatment. Clinical discussion: The patient shows relative neglect in oral healthcare given the subpar oral health features she exhibited and decline of further treatment options presented to her. This is common in the population as some abnormal oral presentations and features are perceived as normal in the population, which can be attributed to poor knowledge of oral health practices, which affects the illness seeking behaviour of individual. Conclusion: Calculus deposition in the oral cavity requires a hard surface for formation, and proper oral hygiene practices are essential to mitigate its adverse effects, particularly among the elderly who may require additional attention due to their unique physiological changes.

Outcomes of co-designed communities of practice that support members to address public health issues.

Communities of practice are commonly used to support members in responding to public health issues. This study evaluated the outcomes of five co-designed communities of practice to determine if members' expectations were met, if knowledge sharing between members extended to knowledge translation, and if that supported members in addressing public health issues. Data were collected through an initial needs assessment, observations were made during community of practice sessions over 1 year, and qualitative interviews were conducted at the end of that year. The findings provided evidence that members' expectations were met, knowledge sharing took place within the communities of practice, and personal benefits gained supported members in advancing knowledge sharing with other members to knowledge translation outside their community of practice. Results demonstrate three outcomes of knowledge translation for members: disseminating knowledge to others, applying knowledge to make small-scale changes in practice and leveraging the knowledge to expand its reach beyond members' organizations. While the scale and speed of expanding outcomes were below initial expectations as indicated in the initial needs assessments, members remained optimistic about achieving larger-scale impacts in the future. This study showed that communities of practice achieve gradual progress rather than quick wins. Co-design supports the facilitators in meeting members' needs, which can positively contribute to members sharing knowledge and translating that knowledge to support their practice to address public health issues.

Exploring the Lagged Correlation Between Baidu Index and Influenza-Like Illness - China, 2014-2019.

Introduction: This study investigated the lagged correlation between Baidu Index for influenza-related keywords and influenza-like illness percentage (ILI%) across regions in China. The aim is to establish a scientific foundation for utilizing Baidu Index as an early warning tool for influenza-like illness epidemics. Methods: In this study, data on ILI% and Baidu Index were collected from 30 provincial-level administrative divisions (PLADs) spanning April 2014 to March 2019. The Baidu Index was categorized into Overall Index, Ordinary Index, Prevention Index, Symptom Index, and Treatment Index based on search query themes. The lagged correlation between the Baidu Index and ILI% was examined through the cross-correlation function (CCF) method. Results: Correlating the Baidu Overall Index of 30 PLADs with ILI% revealed CCF values ranging from 0.46 to 0.86, with a median lag of 0.5 days. Subcategory analysis indicated that the Prevention Index and Symptom Index exhibited quicker responses to ILI%, with median lags of -9 and -0.5 days, respectively, compared to 0 and 3 days for the Ordinary and Treatment Indexes. The median lag days between the Baidu Index and the ILI% were earlier in the northern PLADs compared to the southern PLADs. Discussion: The Prevention and Symptom Indexes show promising predictive capabilities for influenza-like illness epidemics.

An Overview of Appropriate Medical Practice and Preparedness in Radiation Emergency Response.

Radiation emergencies involving high doses of nuclear radiation pose significant risks from exposure to ionizing radiation in various scenarios. These situations include transportation accidents involving radioactive materials, occupational exposure, nuclear detonations, dirty bombs, and nuclear power plant accidents. In addition to the immediate risks of acute radiation syndrome (ARS) and related diseases, long-term exposure can increase the risk of other health issues such as cardiovascular disease and cancer. Vulnerable populations, including pregnant women and children, face particular concern due to potential impacts on their health and the health of unborn babies. The severity of ARS depends on several factors such as radiation dose, quality, dose rate, exposure uniformity, and individual biological responses. Bioindicators are biological responses or markers that help assess the severity and effects of radiation exposure on an individual. Bioindicators can include physical symptoms such as nausea, vomiting, and diarrhea, or laboratory tests such as changes in blood cell counts and gene expression that can help in assessing and treating exposed individuals. Additionally, early prodromal symptoms such as vomiting, diarrhea, and erythema can provide important clues for diagnosis and treatment. Developing a comprehensive plan for radiation emergencies is vital for safeguarding public health, infrastructure, and the environment. First responders play a critical role in establishing safety perimeters, triage, and coordination with various stakeholders. Education and training are essential for medical personnel and the public. This article provides general recommendations and identifies challenges to effective radiation emergency preparedness and response.

Evaluating a novel model of hepatitis B care, Hep B PAST, in the Northern Territory of Australia: results from a prospective, population-based study.

Background: The Northern Territory (NT) has the highest prevalence of chronic hepatitis B (CHB) in Australia. The Hep B PAST program aims to improve health outcomes for people living with CHB. Methods: This mixed methods study involves First Nations peoples living in the NT. We used participatory action research principles across three steps: 1. Foundation step: establishing hepatitis B virus (HBV) status and linkage to care; 2. Capacity building: training the health workforce; 3. Supported transition to primary healthcare: implementation of the "Hub and Spoke" model and in-language resources. Analysis occurred at three time points: 1. Pre-Hep B PAST (2018); 2. Foundation step (2020); and 3. Completion of Hep B PAST (2023). Evaluation focuses on four key indicators, the number of people: 1) with documented HBV status; 2) diagnosed with CHB; 3) receiving care; and 4) receiving treatment. Findings: Hep B PAST (2018-23) reached 40,555 people. HBV status was documented in 11% (1192/10,853), 79.2% (26,075/32,915) and 90.8% (28,675/31,588) of people at pre-Hep B PAST, foundation step, and completion respectively. An estimated 99.9% (821/822) of people were diagnosed, 86.3% (709/822) engaged in care, and 24.1% (198/822) on antiviral treatment at completion. CHB prevalence in the study population is 2.6%, decreasing from 6.1% to 0.4% in the pre- and post-vaccination cohorts. Interpretation: Hep B PAST is an effective model of care. Partner health services are exceeding elimination targets. This model could enable other countries to enhance the cascade of care and work towards eliminating HBV.

Identification of sialic acid receptors for influenza A virus in snakes.

The tissue tropism and the wide host range of influenza A viruses are determined by the presence of sialic acid (SA) α2,3-Gal and SA α2,6-Gal receptors. Recent studies have shown that animals possessing both receptors allow for the rearrangement and emergence of new viral strains of public health importance. This study aimed to evaluate the expression and distribution of human and avian influenza A receptors in nine Neotropical snake species using lectin immunohistochemistry. We selected 17 snakes that were examined post mortem at the Veterinary Pathology Sector of the Universidade Federal de Minas Gerais between 2019 and 2023. Sections of nasal turbinate, trachea, lung, oral mucosa, stomach and intestine were subjected to immunohistochemical analysis using the lectins Maackia amurensis and Sambucus nigra. This research detected, for the first time, co-expression of SA α2,3-Gal and SA α2,6-Gal receptors in the respiratory and digestive tracts of snakes, indicating the possible susceptibility of these species to influenza A virus of avian and human origin. Consequently, snakes can be considered important species for monitoring influenza A in wild, urban and peri-urban environments. More studies should be conducted to investigate the role of snakes in influenza A epidemiology.

Harnessing the Power of Infection Prevention and Public Health Data Systems to Support Healthcare in Washington State During the COVID-19 Pandemic.

BACKGROUND: State health departments' (SHD) role in infection prevention and control (IPC) includes robust educational and consultative services for various healthcare settings. During the COVID-19 pandemic, Washington-SHD (W-SHD) IPC staff conducted remote and onsite infection control assessment and response (ICAR) consultations for long-term care and non-LTC healthcare facilities. METHODS: ICAR consultations were classified as "reactive" in response to a COVID-19 outbreak or "proactive" to help facilities improve IPC protocols. Facility addresses were geocoded to census tracks, classifying urban/rural areas. Facility types and characteristics were analyzed, assessing impacts of repeat visits. All descriptive statistics, Pearson's Chi-square tests and odds ratios were calculated. RESULTS: Between 3/2020 and 12/2022, W-SHD conducted 3,093 ICARs at 1,703 healthcare facilities in 94.9% (37/39) of WA counties. Of the total visits, most were in LTC (90.5%) and 48.9% were reactive. Facilities with initial onsite ICARs had 1.5 times the odds of having a repeat visit than facilities with initial remote visit (95%CI: 1.21, 1.87). DISCUSSION: Maintaining strong connections with healthcare facilities can help bolster infection prevention practices and minimize loss of information at the facility level. CONCLUSIONS: Evidence-based findings on the sustainability of the W-SHD's ICAR services during the COVID-19 pandemic illustrated the value of public health IPC programs.

Association between hospital procedure volume, socioeconomic status, comorbidities, and adverse events related to surgical abortion: A nationwide population-based cohort study.

BACKGROUND: Limited evidence exists on the influence of hospital procedure volume, socioeconomic status, and comorbidities on surgical abortion outcomes. OBJECTIVE: Our study aimed to assess the association between hospital procedure volume, individual and neighborhood deprivation, comorbidities, and abortion-related adverse events. STUDY DESIGN: A nationwide population-based cohort study of all women hospitalized for surgical abortion was conducted from January 1, 2018, to December 31, 2019 in France. Annual hospital procedure volume was categorized into four levels based on spline function visualization: very low (<80), low ([80-300[), high ([300-650[), and very high-volume (≥650) centers. The primary outcome was the occurrence of at least one surgical-related adverse event, including hemorrhage, retained products of conception, genital tract and pelvic infection, transfusion, fistulas and neighboring lesions, local hematoma, failure of abortion, admission to an intensive care unit or death. These events were monitored during the index stay and during a subsequent hospitalization up to 90 days. The secondary outcome encompassed general adverse events not directly linked to surgery. RESULTS: Of the 112,842 hospital stays, 4,951 (4.39%) had surgical-related adverse events and 256 (0.23%) had general adverse events. The multivariate analysis showed a volume-outcome relationship, with lower rates of surgical-related adverse events in very high-volume (2.25%, aOR=0.34, 95%CI [0.29-0.39], p<0.001), high-volume (4.24%, aOR=0.61, 95%CI [0.55-0.69], p<0.001), and low-volume (4.69%, aOR=0.81, 95%CI [0.75-0.88], p<0.001) when compared to very low-volume centers (6.65%). Individual socioeconomic status (aOR=1.69, 95%CI [1.47-1.94], p<0.001), neighborhood deprivation (aOR=1.31, 95% CI [1.22-1.39], p<0.001), and comorbidities (aOR=1.79, 95%CI [1.35-2.38], p<0.001) were associated with surgical-related adverse events. Conversely, the multivariate analysis of general adverse events did not reveal any volume-outcome relationship. CONCLUSION: The presence of a volume-outcome relationship underscores the need for enhanced safety standards in low-volume centers to ensure equity in women's safety during surgical abortions. However, our findings also highlight the complexity of this safety concern which involves multiple other factors including socioeconomic status and comorbidities that policymakers must consider.

Physical activity, physical fitness and cardiometabolic health among Finnish military workers.

INTRODUCTION: The Western lifestyle challenges national defence. Inactivity, obesity, high BP and elevated lipid and glucose levels as well as tobacco use all increase cardiometabolic risk. The present study was thus aimed at investigating the health and physical activity of employees in a military environment, concentrating on comparisons between soldiers and civilians. METHODS AND DESIGN: A total of 260 employees from 6 brigades were included in the present study. Health status was evaluated with body composition, cardiometabolic risk markers from laboratory samples and a questionnaire concerning lifestyle habits. Body composition was assessed by means of body mass, body mass index, fat percentage and waist circumference. Furthermore, physical activity was examined by the aid of accelerometer recordings for a 2-week period, and physical fitness via aerobic and muscle fitness tests. Finally, upper-quartile active and lower-quartile passive participants were compared, by incorporating mean daily step counts. RESULTS: When standardised by gender, there were no differences between the soldiers and civilians except for the muscle fitness test, in which soldiers performed better. The mean (±SD) moderate to vigorous activity was 0.9±0.3 hours/day in male soldiers and 1.0±0.4 hours/day in male civilians, and respectively sedentary behaviour was 9.5±1.4 hours/day in male soldiers and 8.9±1.7 hours/day in male civilians. The mean (±SD) low-density lipoprotein values were 3.28±0.84 mmol/L in male soldiers and 3.36±0.86 mmol/L in male civilians. In comparing soldiers and civilians, statistically significant differences were observed in body composition, physical fitness, insulin, fasting glucose, triglycerides and high-density lipoprotein values between the upper-quartile active and lower-quartile passive participants, but no difference in low-density lipoprotein values was noticed. CONCLUSIONS: Sedentary behaviour and elevated low-density lipoprotein values seem to increase cardiometabolic disease risk among participants, even if they meet the weekly physical activity demands.

Urgent action needed: addressing the regulatory gap in e-cigarette trade and usage.

Tobacco use is associated with serious health problems. Global efforts, such as the World Health Organization's Framework for Tobacco Control, have reduced tobacco use, but challenges remain. Initially perceived as aids for smoking cessation, e-cigarettes have gained popularity among young people and non-smokers. Government approaches to regulating e-cigarettes range from treating them like tobacco, requiring a prescription for their use to outright bans. Although touted as a valuable alternative, evidence suggests that increased e-cigarette use carries potential direct and indirect health risks, necessitating urgent regulatory measures on a global scale. Lack of defined and uniform regulations poses substantial public health risks, compounded by marketing targeting vulnerable groups. Immediate interventions, public awareness, and research are essential to effectively control the current e-cigarette epidemic.

Mortality in sea lions is associated with the introduction of the H5N1 clade 2.3.4.4b virus in Brazil October 2023: whole genome sequencing and phylogenetic analysis.

Clade 2.3.4.4b highly pathogenic avian influenza (HPAI) H5N1 virus was detected in the South American sea lions found dead in Santa Catarina, Brazil, in October 2023. Whole genome sequencing and comparative phylogenetic analysis were conducted to investigate the origin, genetic diversity, and zoonotic potentials of the H5N1 viruses. The H5N1 viruses belonged to the genotype B3.2 of clade 2.3.4.4b H5N1 virus, which was identified in North America and disseminated to South America. They have acquired new amino acid substitutions related to mammalian host affinity. Our study provides insights into the genetic landscape of HPAI H5N1 viruses in Brazil, highlighting the continuous evolutionary processes contributing to their possible adaptation to mammalian hosts.

Impacts of industrial actions, protests, strikes and lockouts by health and care workers during COVID-19 and other pandemic contexts: a systematic review.

BACKGROUND: Public health emergencies of international concern (PHEICs) as the COVID-19 pandemic and others that have occurred since the early 2000s put enormous pressure on health and care systems. This is being a context for protests by health and care workers (HCWs) because of additional workload, working conditions and effects on mental and physical health. In this paper, we intended to analyze the demands of HCWs associated with industrial actions, protests, strikes and lockouts (IAPSLs) which occurred during COVID-19 pandemic and other PHEICs; to identify the impact of these grievances; and describe the relevant interventions to address these IAPSLs. METHODS: We included studies published between January 2000 and March 2022 in PubMed, Embase, Scopus, BVS/LILACS, WHO's COVID-19 Research Database, ILO, OECD, HSRM, and Google Scholar for grey literature. Eligibility criteria were HCWs as participants, IAPSLs as phenomenon of interest occurring in the context of COVID-19 and other PHEICs. GRADE CERQual was used to assess risk of bias and confidence of evidence. RESULTS: 1656 records were retrieved, and 91 were selected for full-text screening. We included 18 publications. A system-wide approach, rather than a limited approach to institutions on strike, makes it possible to understand the full impact of the strike on health and care services. PHEICs tend to aggravate already adverse working conditions of HCWs, acting as drivers for HCWs strikes, leading to staff shortages, and financial issues, both in the North and in the Global South, particularly evident in Asia and Africa. In addition, issues related to deficiencies in leadership and governance in heath sector and lack of medical products and technologies (e.g., lack of personal protective equipment) were the main drivers of strikes, each contributing 25% of the total drivers identified. CONCLUSIONS: It is necessary to focus on the preparedness of health and care systems to respond adequately to PHEICs, and this includes being prepared for HCWs' IAPSLs, talked much in the context of COVID-19 pandemic. Evidence to assist policymakers in defining strategies to respond adequately to the health and care needs of the population during IAPSLs is crucial. The main impact of strikes is on the disruption of health care services' provision. Gender inequality being a major issue among HCWs, a proper understanding of the full impact of the strike on health and care services will only be possible if gender lens is combined with a systemic approach, rather than gender-undifferentiated approaches limited to the institutions on strike.

Dataset on a reliability generalization meta-analysis of the Oxford COVID-19 vaccine hesitancy scale.

The Oxford COVID-19 Vaccine Hesitancy Scale is a 7-item psychometric scale developed by Freeman and colleagues a year after detecting the first case of the disease in 2019. The scale assesses people's thoughts, feelings, and behavior toward COVID-19 vaccines. A comprehensive search of major electronic databases, including Scopus, Clarivate Analytics, and PubMed, was conducted to extract eligible articles for inclusion in this meta-analysis. This paper reports information on data collected for a reliability generalization meta-analysis of the Oxford COVID-19 Vaccine Hesitancy Scale. The dataset incorporates information on the average reliability of the scale as measured with Cronbach's alpha in 20 studies included in the meta-analysis. Several benefits can be derived from the dataset. In particular, the research community would find this dataset beneficial as it can enhance their understanding of the health challenges of COVID-19, helping them come up with better solutions to eradicate the disease.

Patient perceptions of nurses' cultural competence in public sector hospitals in Gauteng.

Background: Healthcare institutions are increasingly receiving patients from diverse cultural backgrounds because of migration, rapid urbanisation, and easier access to healthcare. Because the satisfaction of these patients is linked to their perceptions of appropriate cultural care, understanding patient perspectives about cultural competence is imperative. Additionally, patient perceptions about nurses' cultural competence are largely unexplored in South Africa. Aim: This study explored how the concept of cultural competence is perceived by patients. Setting: Three public sector hospitals in Gauteng, one from each of the three different levels of public sector hospitals - district (level one), regional (level two), and academic (tertiary, level three). Methods: This study derives from the qualitative phase of a larger sequential exploratory mixed methods study. The study population was patients in public sector hospitals. A total of 21 interviews were conducted after purposive stratified sampling was done. Data analysis followed Tesch's eight steps of data analysis. Results: Patients in public sector hospitals in Gauteng believe consideration of culture is important in nursing. They identified the cultural needs they would like nurses to acknowledge, such as being asked about their food preferences and mentioned the need to evaluate nurses' level of cultural competence. Conclusion: Patient perceptions about cultural competence and their cultural needs can assist nurses in gauging how culturally competent they are and improving care to patients. Contribution: Patients' perceptions revealed that nurses must be competent to acknowledge their specific cultural needs such as food, language preferences, and religious practices.

Barriers to enrolment of clients into community client led anti-retroviral therapy delivery (CCLAD) in selected health facilities in Kasese district, Uganda.

Background: Community Client Led Anti-retroviral therapy Delivery (CCLAD) Model has been associated with increased community participation and ownership, which leads to better treatment outcomes with reduced workload and increased client satisfaction of health services. Aim: To explore the barriers to enrolment of eligible clients into CCLAD in selected health facilities in Kasese District, Uganda. Materials & methods: Analytical cross-sectional study utilizing mixed method approach was conducted among 384 PLWHIV attending public health facilities of Kasese District. Sampling was done by simple random sampling method. Data was collected using researcher-administered questionnaire method and interview guide. Results: Most of the respondents 253(65.9%) had not yet enrolled into CCLAD. This was due to some client-related factors such as non-disclosure of HIV sero-status (p=0.040), person to whom HIV sero-status was disclosed to (p=0.009), not having ever heard about CCLAD (p=0.000), incorrect description of CCLAD (p=0.000), limited knowledge of advantages of CCLAD (p=0.000) or disadvantages of CCLAD (p=0.003). Other barriers were; failure to have access to organizations or groups that support PLWHIV to get treatment (p=0.025) and duration of ART refills [AOR=1.637, 95% CI (0.820 - 3.270)]. Conclusion: Adoption of CCLAD model among PLWHIV in Kasese District is still low.

Infectious Diarrhea Risks as a Public Health Emergency in Floods; a Systematic Review and Meta-Analysis.

Introduction: Infectious diarrhea, a significant global health challenge, is exacerbated by flooding, a consequence of climate change and environmental disruption. This comprehensive study aims to quantify the association between flooding events and the incidence of infectious diarrhea, considering diverse demographic, environmental, and pathogen-specific factors. Methods: In this systematic review and meta-analysis, adhering to PROSPERO protocol (CRD42024498899), we evaluated observational studies from January 2000 to December 2023. The analysis incorporated global data from PubMed, Scopus, Embase, Web of Science, and ProQuest, focusing on the relative risk (RR) of diarrhea post-flooding. The study encompassed diverse variables like age, sex, pathogen type, environmental context, and statistical modeling approaches. Results: The meta-analysis, involving 42 high-quality studies, revealed a substantial increase (RR = 1.40, 95% CI [1.29-1.52]) in the incidence of diarrhea following floods. Notably, bacterial and parasitic diarrheas demonstrated higher RRs (1.82 and 1.35, respectively) compared to viral etiologies (RR = 1.15). A significant sex disparity was observed, with women exhibiting a higher susceptibility (RR = 1.55) than men (RR = 1.35). Adults (over 15 years) faced a greater risk than younger individuals, highlighting age-dependent vulnerability. Conclusion: This extensive analysis confirms a significant correlation between flood events and increased infectious diarrhea risk, varying across pathogens and demographic groups. The findings highlight an urgent need for tailored public health interventions in flood-prone areas, focusing on enhanced sanitation, disease surveillance, and targeted education to mitigate this elevated risk. Our study underscores the critical importance of integrating flood-related health risks into global public health planning and climate change adaptation strategies.

REALITIES in health disparities: Researching Evidence-based Alternatives in Living, Imaginative, Traumatised, Integrated, Embodied Systems.

Introduction: Under the backdrop of pervasive health inequalities, public health professionals, researchers and non-academic partners in the United Kingdom are mobilising to understand how and in what ways community assets can address health disparities at scale in complex systems. While there is recognition that cultural, natural and community resources can improve health outcomes, these are unequally dispersed with lack of integration in communities and health and social care systems. Researching Evidence-based Alternatives in Living, Imaginative, Traumatised, Integrated, Embodied Systems (REALITIES) is a participatory action research Scottish consortium of 57 with established community asset hubs in five localities with strong relationships uniting conflicting ways of seeing the world. Our collective of lived and felt experience community members, community-embedded researchers, academics and non-academics draws upon a variety of practices, methods, datasets and philosophies to expand existing approaches to tackling health inequalities. Methods: We present conceptual and theoretical underpinnings for our co-produced systems-level model and empirical findings from testing REALITIES across three disadvantaged localities (November 2022, ongoing). After explaining the context that led to the development of the new scalable REALITIES model for integrated public systems to interface with 'assets', we detail philosophical pillars and guiding principles for our model and how we applied these mechanisms to explain how integrated partnership working can lead to improved health outcomes across multiple public systems. Results: We present a meta-analysis from co-producing and testing the model, showing how measuring change in complex public systems involves critical investigation of People, Process, Place, Price, Power and Purpose. Our critique reflects on power imbalances and inequities in Research-practice-Policy (RPP) partnerships and suggestions for how to nurture healthy ecosystems: overcoming barriers and enabling participation; reflecting on challenges of scaling up, testability and complexity of RPP partnerships; moving from siloed learning to transdisciplinary collaboration in practice; ensuring knowledge exchange has direct impact on communities and frontline practitioners; embedding relational ethics and safeguarding into daily practice. Discussion: We propose the REALITIES model to unite alternative, sometimes conflicting, ways of thinking about public systems and community assets by continuously reflecting on entanglements between different assumptions about knowledge, reality, evidence, and unnecessary binaries between creative methodologies and scientific method.

Knowledge, attitudes and practices about air pollution and its health effects in 6th to 11th-grade students in Colombia: a cross-sectional study.

Introduction: Globally, air pollution is the leading environmental cause of disease and premature death. Raising awareness through environmental education and adequate communication on air quality could reduce the adverse effects. We aimed to assess the knowledge, attitudes, and practices (KAP) regarding air pollution and health and determine the factors associated with these KAP in children and adolescents. Methods: In 2019-2020, a cross-sectional study was conducted on 6th-11th grade high school students in five municipalities in Colombia. Variables collected included: age, sex, private or public school, any medical history, emergency room visits due to respiratory symptoms in the last year, and whether students played sports. The main exposure was the School Environmental Project. The outcomes were the KAP scale [0% (the lowest score) to 100% (the highest score)]. The factors associated with KAP levels were evaluated with independent mixed regressions due to the multilevel structure of the study (level 1: student; level 2: school), and the exponential coefficients (95% confidence interval-CI) were reported. Results: Among 1,676 students included, 53.8% were females. The median knowledge score about air pollution and its health effects was 33.8% (IQR: 24.0-44.9), 38.6% knew the air quality index, 30.9% knew the air quality alerts that occurred twice a year in these municipalities and 5.3% had high self-perceived knowledge. Positive attitudes, pro-environmental practices, being female, grade level, attending a private school, having respiratory diseases, and the school environmental project importance were associated with higher knowledge scores. The median attitudes score was 78.6% (IQR: 71.4-92.9). Pro-environmental attitudes were associated with knowledge-increasing, being female, attending a private school, and the school environmental project. The median pro-environmental practices score was 28.6% (IQR: 28.6-42.9). During air quality alerts, 11.6% had worn masks, 19% had reduced the opening time of windows and 15.9% avoided leaving home. Pro-environmental practices were associated with knowledge-increasing and attitudes-increasing, and lower practices with higher grade levels, visiting a doctor in the last year, and practicing sports. Discussion: Children and adolescents have low knowledge scores and inadequate pro-environmental practices scores regarding air pollution. However, they demonstrate positive attitudes towards alternative solutions and express important concerns about the planet's future.
