BACKGROUND: In recent years, the prevalence of dust events has increased in the region and
the world. According to the Meteorological Organization, the most frequent days with dust events
are on stations located in Khuzestan province. Objective: Assessment of the effects of dust events
and meteorological elements on stroke morbidity in health in Iran: a health promotion approach.
MATERIALS AND METHODS: The present study was a retrospective cohort study 2020 and 2013
provided between based on ecological data‑based on population. Information about patients with
stroke was obtained from the hospital. Information on the dust events and meteorological elements
was also from the data center of the Meteorological Organization of Iran. Using STATA the correlation
between the diseases and the, 14 statistical software version occurrence of dust events and changes
in meteorological elements was obtained and the statistical model (Spearman correlation coefficient)
individually estigate the equation was used inv modified by Poisson regression simultaneous effect
of variables.
RESULTS: the results of adjusted statistical models show that increasing the severity of dust
event increases the risk of stroke in males (lag 0–21 confidence interval [CI] 95% = 1.496–1.0067
relative risk [RR] = 1.03 P = 0.01). Increasing the average wind speed also increases the
risk of stroke in males (lag 0–3 CI 95% = 1.0491–0.9996 RR = 1.02 P = 0.05). Increased
rainfall and average relative humidity increase the risk of stroke in people under 60 years
(lag 0–7 CI 95% = 1.0012–0.9058 RR = 1.95 P = 0.05). Increasing the average daily temperature
reduces the risk of stroke in males (lag 0–3 CI 95% = 0.9874–0.9254 RR = 0.51 P < 0.001).
CONCLUSION: Increasing the intensity of dust storms along with meteorological elements has
increased the risk of stroke. However, increasing the average temperature has had a protective
effect on the risk of stroke.
