claimIn 2021, the incidence, mortality, and disability-adjusted life year (DALY) rates for non-communicable diseases (NDs) were inversely correlated with the Socio-Demographic Index (SDI) across 204 countries and regions.
referenceThe 2021 Global Burden of Disease (GBD) study analyzed nutrient deficiency disorders (NDs) across 204 countries and 21 regions from 1990 to 2021, evaluating incidence, prevalence, deaths, and disability-adjusted life years (DALYs).
measurementIn 2021, regions with low Socio-Demographic Index (SDI) reported an Age-Standardized Incidence Rate (ASIR) of 19,047.59 cases per 100,000, an Age-Standardized Prevalence Rate (ASPR) of 44,208.88 cases per 100,000, an Age-Standardized Mortality Rate (ASMR) of 8.73 per 100,000, and DALYs of 1,319.28 per 100,000.
claimHigher Socio-Demographic Index (SDI) levels are associated with lower disability-adjusted life years (DALYs), as well as reduced age-standardized incidence rates (ASIR), prevalence rates (ASPR), and mortality rates (ASMR) for non-communicable diseases.
measurementThe age-standardized disability-adjusted life years (DALYs) rate for nutrient deficiency disorders (NDs) was 657.62 per 100,000 individuals (95% UI: 489.93–869.58) in 2021.
measurementIn 2021, regions with high Socio-Demographic Index (SDI) reported an Age-Standardized Incidence Rate (ASIR) of 1,671.71 cases per 100,000, an Age-Standardized Prevalence Rate (ASPR) of 6,458.84 cases per 100,000, an Age-Standardized Mortality Rate (ASMR) of 0.95 per 100,000, and DALYs of 118.26 cases per 100,000.
measurementIn 2021, the highest actual prevalence, incidence, mortality, and disability-adjusted life years (DALYs) of nutritional deficiencies were observed in China and India.
measurementIn 2021, the global number of DALYs related to nutrient deficiency disorders was 4,891.93 million (95% UI: 3,598.61, 6,498.54 million).
measurementBetween 1990 and 2021, incidence, prevalence, deaths, and Disability-Adjusted Life Years (DALYs) showed a downward trend in both men and women, suggesting progress in public health and medical interventions.
claimThe incidence, prevalence, mortality, and Disability-Adjusted Life Years (DALYs) of dietary deficiencies differ significantly among regions.
claimOver the 30-year period from 1990 to 2021, the decline rate for non-communicable disease incidence and disability-adjusted life years (DALYs) was higher for males than for females, while the opposite trend was observed for prevalence and mortality rates.
measurementIn 2021, the highest age-standardized incidence, prevalence, mortality, and DALYs related to nutritional deficiencies were recorded in Somalia.
measurementGlobal Disability-Adjusted Life Years (DALYs) due to nutritional deficiencies decreased from 78,674,224 in 1990 to 48,919,261 in 2021.
measurementGlobally, from 1990 to 2021, the absolute incidence of non-communicable diseases was reduced by 39%, deaths by 61%, and disability-adjusted life years (DALYs) by 38%, while prevalence increased by 4.5%.
claimDisability-Adjusted Life Years (DALYs) measure the impact of nutrient deficiencies by combining years of life lost (YLL) due to premature death and years lived with disability (YLD).
claimFor non-communicable diseases, the overall rates of incidence, prevalence, and disability-adjusted life years (DALYs) decrease with increasing age.
measurementThe average annual reduction in disability-adjusted life years (DALYs) for nutritional deficiencies was 0.59% for men and 0.47% for women, according to the Global Burden of Disease 2021 study.

procedureThe 'Diet-Related Morbidity/Mortality Statistics' indicator uses two primary parameters: (1) the prevalence of individuals with physician-diagnosed obesity, cardiovascular diseases (CHD, stroke, hypertension), type II diabetes, osteoporosis, neurodegenerative diseases, and obesity-related cancers; and (2) disability-adjusted life years (DALYs) as a measure of disease burden associated with nutrition-related factors like high blood pressure, high cholesterol (total and LDL), and high blood sugar (insulin resistance/diabetes).
claimThe abbreviation DALY stands for disability-adjusted life years.
procedureThe methodology for measuring physical inactivity as a nutritional indicator includes tracking attributable disability-adjusted life years (DALYs) from physical inactivity and utilizing Physical Activity Questionnaires such as the WHO Global Physical Activity Questionnaire (GPAQ) and the International Physical Activity Questionnaire (IPAQ).
Measurement of diets that are healthy, environmentally sustainable ... frontiersin.org 3 facts
procedureThe research team developed 10 categories for health outcomes: cancer; cardiovascular diseases; mortality, number of deaths averted, or years of life saved (non-specific disease); type 2 diabetes; stroke; disability-adjusted life year (DALY) (non-specific disease); weight, overweight, or obesity; composite health indicators; quality-adjusted life year (QALY) or quality of life (QOL) related to non-specific diseases; or other.
claimThe under-representation of low-income countries in healthy diet research is attributed to a lack of datasets, the use of data derived from high-income settings, and a focus on health outcomes where data is plentiful, such as non-communicable diseases (NCDs), all-cause mortality, and disability-adjusted life years (DALYs).
claimMost indicators used in modeling diet and health focus on specific dietary exposures in relation to a small number of outcomes, such as all-cause mortality risk, Disability-Adjusted Life Years (DALYs), or diet-related non-communicable diseases like cardiovascular disease (CVD), certain cancers, and type 2 diabetes (T2D).

measurementHealth cost indicators in diet assessment include two metrics for health savings (cost-benefit due to health improvements and cost per DALYs saved) and two metrics for health costs attributed to obesity.
claimThe most frequently used health outcome indicators were Disability Adjusted Life Years (DALYs) associated with cardiovascular disease, diabetes, and cancer.
