NCT06188312

Brief Summary

The study aims:

  • To identify the main occupational health hazards to which the superphosphate fertilizer industry workers are exposed.
  • To identify the respiratory and auditory health effects of these hazards and associated risk factors among those workers.
  • To clarify the knowledge, attitudes, and practices of workers towards the chemical health hazards affecting the respiratory system (dust and hazardous gases).
  • To assess the effect of health education program on workers' knowledge, attitudes, and practices towards these hazards and the use of personal protective equipment (PPE).

Outcome Measures

Primary Outcomes (1)

  • prevalence of respiratory and auditory problems among workers of the superphosphate fertilizer factory.

    percentage of workers who had respiratory and auditory affection

    1-1-2024 to 1-6-2024

Secondary Outcomes (1)

  • Mean score difference of knowledge, attitudes, and practices before and after the health education program among workers of the superphosphate fertilizer factory.

    1-6-2024 to 1-12-2024

Interventions

A pretest questionnaire will be filled out, asking the participants about their knowledge, attitudes, and practices toward chemical hazards and the use of personal protective equipment (PPE) then analysis of the obtained pre-test data will be done. we will apply a health education program. Development phase: developing the message of the health education program and preparing the materials (slide presentation, brochures, and an educational video).Implementation phase: A group health education session through face-to-face, one hour long, interactive lecture combined with slide presentation will be carried out by the researcher. Evaluation phase: A post-test will be done, after 6 months of the first session, to assess the changes of their knowledge and attitude after the intervention.

Sampling MethodProbability Sample
Study Population

Phase one(survey): The total number of workers in the factory is 660.They were classified according to the levels of exposure to high exposure (including the production and engineering sectors) and low exposure (including the administrative sector). * The high exposure group represented 76 % of workers \[58% (380 workers) of the production workers and 18% (120 workers) of the engineering sector\]. * The low exposure group represented 24% (160 workers) of the administrative sector.

You may qualify if:

  • All workers in the superphosphate fertilizer factory with a duration of work more than one year.

You may not qualify if:

  • Workers who had history of any chronic respiratory diseases before employment, and those who had history of hearing loss before employment.
