- The central area of Sub-Saharan Africa bears the greatest burden of worldwide nutritional deficiencies (NDs) prevalence, potentially due to genetic predisposition, higher prevalence of hypertension and diabetes, inadequate access to health care, and lack of understanding of stroke risk factors.
- Between 1990 and 2021, the greatest substantial decline in the age-standardized incidence rate (ASIR) of nutritional deficiencies occurred in sub-Saharan Africa, with an estimated annual percentage change (EAPC) of -2.81 (-3.01 to 2.62).
- In low-SDI (Sociodemographic Index) regions such as Sub-Saharan Africa and South Asia, political instability and violence cause food supply disruptions, infrastructure loss, and a lack of health resources, which compound the burden of nutritional deficiencies.
- The combination of high-salt, high-fat diets and rapid urbanization in South Asia and Sub-Saharan Africa has resulted in an increase in metabolic disorders such as hypertension and diabetes.
- The Age-Standardized Prevalence Rate (ASPR) for nutritional deficiencies is highest in central sub-Saharan Africa at 44,824.1 per 100,000 people, followed by South Asia at 40,854.69 per 100,000 people, and sub-Saharan Africa at 39,924.67 per 100,000 people.
- Sub-Saharan Africa has the greatest age-standardized disability-adjusted life expectancy (DALY) for nutritional deficiencies, with 4,027.09 per 100,000 people (95% UI: 3,326.07–5,033.9).
- Nutritional deficiencies may be more prevalent in South Asia and Sub-Saharan Africa due to poor eating habits (such as excessive salt and processed foods), fast urbanization, hereditary factors, and insufficient health-care resources.
