reducing anaemia have failed to substantially reduce the massive burden of anaemia globally over the last few decades.
People become anemic when their blood lacks enough healthy red blood cells to carry oxygen throughout the body. This decreased oxygen delivery causes many of the most common symptoms of anaemia, including fatigue, shortness of breath, lightheadedness, difficulty concentrating and challenges with work and daily life tasks.
In addition to its direct health effects, anaemia can inhibit brain development and fine motor skills in children and heighten the risk of stroke, cardiovascular disease, dementia and other chronic illnesses in older adults. Anaemia during pregnancy can lead to increased rates of anxiety and depression, early labour, postpartum hemorrhage, stillbirth and low birth weight. Infections for both mother and baby are also more likely when the mother is anemic.
We are global health researchers with expertise in epidemiological modeling of anaemia alongside other maternal, neonatal and nutritional disorders.
Our work is part of the Global Burden of Disease Study, a large research study comprehensively estimating health loss due to hundreds of diseases, injuries and risk factors around the globe. Through our analysis, we have produced annual estimates of anaemia prevalence by underlying cause for 204 countries and territories, by age and sex, from 1990 to the present. We have collected thousands of data points across hundreds of sources to produce the most comprehensive picture of anaemia burden.
Anaemia is diagnosed by a simple blood test and can be caused by a number of underlying conditions.
Decreases in healthy red blood cells can occur due to excessive loss of
