Dysphonia Interference in Schoolteachers' Speech Intelligibility in the Classroom

"Among the most common occupations, schooteachers are the ones who experience the most changes throughout their career. Considering this, the present study aims to verify whether dysphonia in three different degrees may compromise the speech intelligibility of schoolteachers in the classroom.

METHOD

Overall, 39 students, average age 10 years, randomly selected from a public school in the Federal District, Brazil (Distrito Federal, Brasil) performed a transcription task of 20 sentences spoken by four distinct female voices in a classroom, one with a control voice (normal), another with mild dysphonia, 1 with moderate dysphonia and another with severe dysphonia. None of the voices in the study presented changes, neither in fluency nor articulation nor neurological changes. The sentences were previously recorded in an acoustically treated booth, with a microphone on a pedestal 5 cm away from the speaker's mouth. For each sentence to be recorded, the speech model was provided by the speech therapist and then repeated by the speaker according to the model. Each voice recorded 5 different sentences, phonetically balanced and with equivalent number of words. The students included in the study underwent auditory, auditory processing, sequential memory for verbal sounds and sound source location tests, fulfilling the normality criteria. They also did not have neurological or motor disorders or learning, speech or language disorders. Academic success was also taken into account. For the experiment, a speaker was placed in front of the classroom, 1 m from the wall and 1 m from the floor, and students were randomly assigned to the classroom seats. After listening to each sentence, some time was assigned for its transcription by each student.

RESULTS

The occurrence of errors was higher in voices with moderate and severe dysphonia, in which a significant difference was found (P ≤0.003) showing that voices with moderate and severe dysphonia were less intelligible than the normal voice (control voice). No difference was found between the normal voice and the mild dysphonic voice. Binary logistic regression analysis also showed that students had a 2.55 times higher chance of making mistakes with moderate dysphonic voice (P ≤0.011), and that this chance was 3.06 times greater for severe dysphonic voice (P ≤0.002) when compared to the normal voice (control voice).

CONCLUSION

Moderate and severe dysphonia in the voices of schoolteachers interferes with the intelligibility of students, and the greater the degree of dysphonia of the teacher, the greater the chance that the student will make intelligibility errors."

Work-related rumination and worry at bedtime are associated with worse sleep indicators in schoolteachers: a study based on actigraphy and sleep diaries

OBJECTIVE/BACKGROUND

Work-related rumination and worry are indicators of occupational stress which can impact sleep when they occur close to bedtime. This study examined the relationship between these repetitive thoughts before sleep with objective and subjective sleep parameters.

METHODS

A microlongitudinal study was carried out with schoolteachers who answered questions on rumination and worry before sleep, wore a wrist actigraph, and completed a sleep diary for 5 to 7 consecutive days. Analysis used mixed-effects repeated measures linear models adjusted for sociodemographic, lifestyle, and health status.

RESULTS

Among the 134 schoolteachers studied, 64.9% were women and were aged 41.9 ± 9.5 years. In the fully adjusted analysis, actigraphy indicated that a wake-up time <6:30 a.m. was associated with both rumination (relative risk (RR) = 1.67; 95% confidence interval (CI) = 1.21-2.31) and worry (RR = 2.44; 95%CI = 1.63-3.64). Moreover, actigraphy-measured nighttime sleep duration <7 h (RR = 1.23; 95%CI = 1.03-1.47) and self-reported sleep latency >15 min (RR = 1.43; 95%CI = 1.02-2.02) were associated with work-related worry.

CONCLUSIONS

The occurrence of work-related repetitive thoughts before sleep, particularly worry about next-day issues, is associated with an increased risk of impaired objective and subjective sleep indicators. These findings suggest that these cognitive processes related to work should be addressed in strategies aimed at preventing and treating sleep disturbances and their individual and occupational consequences.

Ethiopian teachers: their knowledge, attitude and practice towards epilepsy

BACKGROUND

In Ethiopia where the burden of epilepsy is highest among school age children and teenagers, and where people with epilepsy (PWE) and their relatives suffers from high level of perceived stigma, there had not been any study that assessed the knowledge, attitude and practice of teachers towards PWE. This study aims to assess and understand the social and demographic determinants of knowledge, attitude and practice of teachers towards PLW in Addis Ababa, Ethiopia.

METHODS

Multistage cluster sampling procedure was used to identify twenty schools from three sub cities of Addis Ababa, Ethiopia. Standardized self administered questionnaire was used to collect data from 845 volunteer teachers in the pre identified schools. Frequencies were used to characterize the demographic variables while multiple response frequencies were used to characterize the multiple response variable sets. Non-parametric statistical methods were used to describe the association among the demographic variables of interest and the count sums of multiple response variables which were grouped into biologically and culturally plausible responses.

RESULTS

The most common biologically plausible responses were: brain diseases (26.5 %) from causes, allow my offspring to play with PWE (19.1 %) from attitude, protect the subject from injury (20.4 %) from first aid measures and seek help from medical doctors (52.2 %) from epilepsy treatment. On the contrary, the most common culturally plausible responses were: psychiatric illness (12.9 %) from causes, epilepsy be cured before attendance to school (21.6 %) from attitude, smelling the smoke of struck match (14.2 %) from first aid measures and Holy water treatment (20.3 %) from epilepsy treatment suggestions. The biologically and culturally plausible responses were negatively correlated. Level of education was positively associated with biologically plausible responses while teaching experience was negatively correlated with culturally plausible responses.

CONCLUSION

A high percentage of teachers in Addis Ababa considered epilepsy as a psychiatric illness closely linked to insanity. This explains their suggestions of Holy water treatment and Church healing sessions as epilepsy remedies. This is in agreement with Ethiopian culture, in which evil spirit and insanity are believed to be better treated by religious remedies than with modern medical treatments. Incorporating special needs educational training courses in the curriculum of teachers training may help them shift their knowledge, attitudes and practices from that of the culturally plausible to biologically plausible one.

Impact of Dental Health Education on "Specific Learning Needs" Children

Introduction: This article compares and evaluates the effect of dental health education through schoolteachers and dental health professionals to “specific learning needs” children attending special school.

Materials and methods: A total of 71 “specific learning needs” children attending special school participated in the study. The baseline oral hygiene index-simplified (OHI-S) for all the participants was recorded. The training of schoolteachers was done using audiovisual and verbal methods on dental health facts and how to provide instructions on oral hygiene measures for reinforcing to the students. The students were randomly divided into three groups: Group 1 – No further dental health education by the schoolteachers or by the dental professionals was given to these students after the initial oral health education. Group 2 – In this group, the trained teachers taught students about the importance of oral health and demonstrated them brushing technique at intervals of 15 days, 1 month and 3 months. Group 3 – The dental professionals imparted dental health education and also demonstrated brushing techniques to these students at intervals of 15 days, 1 month and 3 months. Six months following the intervention a second examination was done to find out the OHI-S scores. Data analysis were done with Statistical Packages for the Social Sciences (SPSS) version 16 using one-way analysis of variance (ANOVA) statistical test.

Results: Group 2 demonstrated significant decline in OHI-S scores after intervention and all the three groups showed a statistically significant difference between the baseline OHI-S score and the scores after 6 months.

Conclusion: Schoolteachers can be utilized for reinforcing dental health education among “specific learning needs” children effectively.
