Context: Climate change is an unavoidable issue that poses a significant risk to
human health on global scale exacerbating respiratory allergic diseases and refers to
long-term changes in average weather patterns over time. Aim: To evaluate the effect
of climate changes program on knowledge and health related behaviors of patients with
respiratory allergic diseases. Method: The study used a quasi- experimental design,
specifically employing a pre/post-test methodology on a purposive sample of (80)
patients with respiratory allergic diseases visited the allergy and immunology outpatient
clinic through four months at Benha University Hospital, Qualubyia Governorate,
Egypt. Tools: Three tools were utilized for data collection: Structured interview
questionnaire, patients' knowledge assessment and patients' climate changes health
related behaviors scale. Results showed a statistically significant increase in the total
patients' knowledge level both immediately and post 3 months of climate changes
program implementation (P= ≤0.05). There was a statistically significant enhancement
in the total patients' health related behaviors level, whereas 86.2% of the studied
patients had unsatisfactory health-related behaviors preprogram implementation, but
improved to be satisfactory as observed in 72.3% & 68.8% of them immediately post
and post 3 months of program implementation, respectively (P= ≤0.05). Besides, a
positive significant correlation between patients' total knowledge score and total health
related behaviors pre and post 3 months of program implementation, as well as a highly
significant correlation immediately post program implementation (P |
