“…Teachers who taught with chalk had twice the risk of developing chronic respiratory symptoms than those who used markers. Similar results were reported in other studies 19 23 59. One possible rationale for this report is that chalk dust contains various chemical impurities that have adverse health effects; when inhaled, these chemicals could aggravate chronic respiratory disease 17.…”

“…Regarding the measurement tool used, this study employed a BMRC Questionnaire to evaluate the chronic respiratory symptoms of school teachers, whereas investigations in Malaysia and Romania used American Thoracic Society Questionnaires. On top of that, the other possible explanation for the difference might be the variation in a study setting, ventilation system, age of the school building, materials used for writing on the board (chalk or marker), teacher-to-student ratio, location of the school (away from the street or schoolyard for exposure to traffic or other sources), type of floor, the indoor and outdoor air quality of the school environment, and classroom construction materials 26 59–61. Furthermore, this distinction may account for differences in culture, belief, and living and earning conditions between countries.…”

ObjectiveThis study aimed to investigate the prevalence and risk factors of chronic respiratory symptoms among school teachers in Gondar city, north-western Ethiopia.DesignA school-based cross-sectional study was conducted from April to May 2019. A self-administered British Medical Research Council Questionnaire was used to assess chronic respiratory symptoms. Data were entered into Epi Info V.7 and Stata V.14 was used for analysis. A multivariable logistic regression analysis was conducted to identify factors associated with chronic respiratory symptoms. The association was determined using adjusted OR (AOR) with a 95% CI at a value of p<0.05.SettingThe study was conducted in public and private schools in Gondar city.ParticipantsA total of 822 teachers participated in this study.Outcome measuresThe primary outcome is the prevalence of chronic respiratory symptoms.ResultsThe total response rate was 97.4%. The majority, 532 (64.7%) of the participants, were male. The mean age (±SD) of the respondents was 36.69 (±6.93) years. The total prevalence of chronic respiratory symptoms in the previous 12 months among teachers in Gondar city was found to be 31.14% (95% CI 27.99% to 34.43%). A family history of respiratory problems (AOR=1.90; 95% CI 1.07 to 3.37), an overweight body mass index (AOR=2.57; 95% CI 1.57 to 4.21), exposure to secondhand cigarette smoke at home (AOR=9.85; 95% CI 4.77 to 20.33), use of chalk (AOR=1.97; 95% CI 1.25 to 3.09), and failure to open windows during class (AOR=2.15; 95% CI 1.02 to 4.52) were risk factors for chronic respiratory symptoms.ConclusionThis study concluded that the prevalence of chronic respiratory symptoms was high among teachers. Making a smoking-free zone, avoiding smoking in public places, improving the ventilation conditions of the classrooms and controlling the chalk dust are all necessary actions to take to reduce chronic respiratory symptoms.

Introducción. La docencia es una de las principales profesiones vinculadas con el desarrollo de una sociedad; como cualquier labor, se encuentra expuesta a diferentes factores de riesgo que pueden generar una enfermedad de origen laboral. Objetivo. Identificar y caracterizar la literatura actual que presente las principales enfermedades de los docentes escolares como consecuencia de su trabajo y/o las condiciones laborales. Materiales y Métodos. Revisión sistemática con búsqueda en las bases de datos Academic Search Complete (EBSCOHOST), APA – PSYCNET, ERIC (Education Resources Information Center), MEDLINE (PubMed), SCOPUS y Open Grey. Se realiza selección pareada independiente bajo criterios de inclusión y análisis de forma narrativa, incluyendo generalidades, información de la enfermedad y desenlaces en docentes. Resultados. Se incluyeron 47 estudios, de los cuales el 25,5% fueron publicados en 2015; Brasil fue el país con mayor aporte temático. La mayoría de los estudios agrupó a los docentes escolares sin distinción de su ciclo (primaria, bachillerato y media). Las principales enfermedades identificadas fueron trastornos de la voz 51,1 %, musculoesqueléticos 23,4 % y psicosociales 21,3 %. Adicionalmente, se identificó que al menos el 50 % de los reportes por país estuvieron relacionados con trastornos de la voz; Brasil e India fueron los países de mayor representatividad. Conclusiones. Las principales enfermedades laborales docentes fueron las relacionadas con trastornos de la voz, musculoesqueléticos y psicosociales; a su vez, estas se relacionan con riesgos físicos, condiciones de seguridad, riesgos biomecánicos y psicosociales en el contexto escolar.
