Temperature and myocardial infarction among migrants in Kuwait
Authors' conclusion
The study revealed a substantial burden of both hot and cold ambient temperatures and the risk of MI at shorter lag days among the migrant population in Kuwait. This study provides valuable insights for government officials to mitigate exposure to extreme temperatures, especially in occupational settings.
Study context
- Population
- Migrants in Kuwait admitted for myocardial infarction (MI) to 17 public hospitals, 2000 to 2017MI cases examined
- Participants
- 26,839 participants
- Comparison
- Association between temperature and MI hospitalisation
- Outcome
- Optimal temperature (lowest MI cases)
Methodological detailsdistributed lag non-linear model, adjusted for seasonality, relative humidity and day of the week
- Distributed lag non-linear model
- Adjusted for seasonality, relative humidity and day of the week
Main finding
As reported in the abstract
Optimal temperature with the lowest MI cases
39.2°C
Further findings
MI risk with hot and cold temperatures
- Elevated MI risks with both hot and cold temperatures, particularly at shorter lag days
- Hot temperatures: pronounced association at lag 0
- Cold temperatures: weak effect at lag 7
- Cumulative risk of MI higher for cold than for hot temperatures
Annual MI cases attributable to temperature · annually
- MI cases attributed to all cool days (below 39.2°C)
- 300 (20.1%)
- MI cases contributed by very hot days (above 39.2°C)
- about 9 (0.6%)
