Global disease burden of stroke attributable to high fasting plasma glucose in 204 countries and territories from 1990 to 2019: An analysis of the Global Burden of Disease Study

BACKGROUND

High fasting plasma glucose (HFPG) is the leading risk factor contributing to the increase of stroke burden in the past three decades. However, the global distribution of stroke burden specifically attributable to HFPG was not studied in depth. Therefore, we analyzed the HFPG-attributable burden in stroke and its subtypes in 204 countries and territories from 1990 to 2019.

METHODS

Detailed data on stroke burden attributable to HFPG were obtained from the Global Burden of Disease Study 2019. The numbers and age-standardized rates of stroke disability-adjusted life years (DALYs), deaths, years lived with disability, and years of life lost between 1990 and 2019 were estimated by age, sex, and region.

RESULTS

In 2019, the age-standardized rate of DALYs (ASDR) of HFPG-attributable stroke was 354.95 per 100 000 population, among which 49.0% was from ischemic stroke, 44.3% from intracerebral hemorrhage, and 6.6% from subarachnoid hemorrhage. The ASDRs of HFPG-attributable stroke in lower sociodemographic index (SDI) regions surpassed those in higher SDI regions in the past three decades. Generally, the population aged over 50 years old accounted for 92% of stroke DALYs attributable to HFPG, and males are more susceptible to HFPG-attributable stroke than females across their lifetime.

CONCLUSIONS

Successful key population initiatives targeting HFPG may mitigate the stroke disease burden. Given the soaring population-attributable fractions of HFPG for stroke burden worldwide, each country should assess its disease burden and determine targeted prevention and control strategies.

Measuring the global, regional, and national burden of type 2 diabetes and the attributable risk factors in all 194 countries

BACKGROUND

No detailed quantitative global, regional, or national estimates of the disability-adjusted life years (DALYs) of type 2 diabetes mellitus (T2DM) are available.

METHODS

We used data from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2017 to estimate the global, regional, and national incidence rates and DALYs of T2DM, as well as the associated risk factors, in all 194 countries and territories by age, sex, and sociodemographic status during the period from 2007 to 2017.

RESULTS

Globally, the age-standardized incidence and DALY rates increased by 3.23% and 5.07% during 2007 to 2017, respectively. The age-standardized incidence and DALY rates in 2017 and the corresponding percentage changes during 2007 to 2017 were highest in the low-middle sociodemographic index (SDI) quintile. Regionally, the highest 2017 age-standardized incidence and DALY rates were observed in Oceania, whereas the largest percentage increases in both rates during 2007 to 2017 were observed in Southeast Asia. Nationally, Iran, the United Kingdom, and Indonesia reported the largest percentage increases in the age-standardized incidence rates, whereas Georgia, Czech Republic, and Iran showed the largest percentage increases in the age-standardized DALY rates. Globally, the largest percentage increases in risk-attributable DALYs were associated with a high body mass index, low physical activity level, high fasting plasma glucose level, and high sugar-sweetened beverage and red meat consumption.

CONCLUSIONS

The global T2DM age-standardized incidence and DALY rates increased globally between 2007 and 2017, especially in the low-middle SDI quintile, Southeast Asia.

Global burden of noncommunicable diseases attributable to high fasting plasma glucose

BACKGROUND

Hyperglycemia is a major public health concern. An understanding of the latest trends of the global burden of noncommunicable diseases (NCDs) by high fasting plasma glucose (HFPG) is critical for determining research priorities and planning health policy.

METHODS

This is a comparative burden-of-disease study. We obtained global, regional, and national data on deaths and disability-adjusted life years (DALYs) of NCDs attributable to HFPG from the Global Burden of Disease Study 2017, performed a secondary analysis of deaths and DALYs by time, age, gender, location, and specific causes, and analyzed their associations.

RESULTS

In 2017, 6.39 million deaths and 166.36 million DALYs from NCDs were attributable to HFPG, accounting for 15.6% and 10.7% of all deaths and DALYs, respectively. The burden's rate decreased with time, increased with age and was significantly higher in males. A negative association was found between the sociodemographic index (SDI) and disease burden, and a positive association was found between SDI and male superiority by gender difference and gender ratio.

CONCLUSIONS

The burden of NCDs attributable to HFPG has increased significantly since 1990 and varied widely across regions. Greater efforts are needed to prevent and control hyperglycemia, especially in less developed countries and among males.
