Abstract

Background: Influenza is a major cause of mortality worldwide. Most influenza-associated deaths are associated with cardiovascular or respiratory disorders. However, a large proportion of influenza-associated deaths do not have respiratory or cardiovascular disorders declared as the underlying cause of death. Diabetic individuals are at increased risk for influenza-mortality. In this study, we assessed the contribution of diabetes to influenza-associated mortality in Mexico.
Methods: Diabetes influenza-associated mortality was estimated for the Mexican population using National Mortality Databases from the Mexican Ministry of Health from 1998 through 2015. Diabetes influenza-associated mortality was calculated applying Serfling cyclical regression models to weekly mortality rates for persons 20-59 years, 60 and more years, and all ages, and by sex.
Results: There was a high correlation between weekly pneumonia and influenza mortality and diabetes-related mortality. Yearly influenza-associated diabetes mortality rates varied between 2.0 and 5.9/100,000. Up until the 2005-2006 season, diabetes-associated mortality rates were higher in females, while after that season rates were higher in males. Yearly influenza-associated diabetes mortality rates for adults 20-59 years of age ranged between 1.7 and 3.4/100,000, while estimates for adults 60 years and older ranged between 16.3 and 46.1/100,000. Approximately one third of estimated diabetes influenza-associated deaths occurred in adults 20-59 years of age. On average, diabetes deaths accounted for 19.6% of estimated influenza-associated all-cause mortality.
Conclusion: Diabetes is a major cause of estimated influenza-associated mortality in Mexico. Health-care authorities and professionals in countries with high diabetes prevalence should be aware of the potential impact of influenza in individuals with this condition.
