Mortality level and predictors in a rural Ethiopian population: community based longitudinal study

Area of Science:

• Demography
• Epidemiology
• Public Health

Background:

• Global mortality rates have declined, but data from low-income countries with absent vital registration systems remain scarce.
• Ethiopia's economic growth and healthcare investments necessitate mortality rate investigation.

Purpose of the Study:

• To investigate mortality rates and identify associated risk factors in Ethiopia.
• To analyze trends in mortality across different age groups and demographic strata.

Main Methods:

• Analysis of longitudinal health and demographic surveillance data from 2009-2012.
• Calculation of crude and standardized mortality rates.
• Cox-regression analysis to determine predictors of mortality, considering altitude, sex, and marital status.

Main Results:

• A crude mortality rate of 4.04 per 1,000 person-years was observed.
• Mortality declined in children under 15 but increased in those aged 65 and above.
• Higher mortality was linked to being male, rural, highland resident, widowed, or divorced.

Conclusions:

• The overall mortality rate in Ethiopia was low, with shifting epidemiological patterns.
• Specific population groups, including males, rural residents, and the elderly, face higher mortality risks.
• Further research is crucial to understand and address the causes of elevated mortality in these vulnerable groups.
