Developing a Cold-Related Mortality Database in Bangladesh

Area of Science:

• Environmental Health
• Public Health
• Epidemiology

Background:

• Cold exposure poses a significant public health risk, particularly in regions with vulnerable populations and limited resources.
• Understanding the patterns of cold-related mortality is crucial for developing effective public health interventions.

Purpose of the Study:

• To create a database of historical cold-related mortality in Bangladesh from 2009-2021.
• To analyze the spatiotemporal distribution, demographic factors, and causes of cold-related deaths.

Main Methods:

• Data collected from online national newspapers covering winter months (December-February) from 2009-2021.
• Analysis of mortality data across eight administrative divisions, focusing on temperature, demographics, and causes of death.

Main Results:

• 1249 cold-related deaths recorded, averaging 104.1 annually.
• Rangpur Division experienced the highest mortality (36.51%) due to lower temperatures and socioeconomic factors.
• Deaths peaked in late December and early January, predominantly in individuals under six and over 65 years old.

Conclusions:

• Cold-related mortality in Bangladesh is a significant issue, with specific geographic and demographic vulnerabilities.
• Interventions targeting Rangpur Division and protecting young children and the elderly are essential.
• Public health policies must address cold hazards to mitigate mortality and illness.
