Anemia is one of the most common nutritional disorders worldwide and represents a significant health burden, particularly affecting women across different stages of life.
Anemia is a condition in which the number of red blood cells or the concentration of hemoglobin is lower than normal, reducing the blood’s ability to carry oxygen to body tissues. Global estimates indicate that hundreds of millions of women of reproductive age are affected by this condition, highlighting the urgent need for coordinated policy-level interventions.
Risk Factors and Main Causes
The causes of anemia in women are multiple and interconnected, requiring a comprehensive approach to prevention and treatment. These causes can be categorized as follows:
1. Chronic Blood Loss:
Heavy menstrual bleeding (menorrhagia) is a major cause of iron-deficiency anemia among women of reproductive age. Significant monthly blood loss depletes the body’s iron stores faster than they can be replenished through diet.
2. Increased Physiological Demands (Pregnancy and Lactation):
During pregnancy, maternal blood volume increases significantly to meet the needs of the developing fetus, doubling the demand for iron and folic acid. If these increased requirements are not met, the risk of anemia rises substantially, potentially leading to serious complications such as preterm birth and low birth weight.
3. Nutritional Deficiency:
Deficiency of micronutrients—especially iron, folic acid, and vitamin B12—is the most common cause of anemia globally. This often results from poor nutrition or unbalanced diets lacking red meat, dark leafy greens, and legumes.
4. Chronic Diseases and Infections:
Certain chronic conditions, such as kidney disease and chronic inflammatory disorders, as well as parasitic infections like malaria and intestinal worms, contribute to worsening anemia, particularly in low-resource settings.
5. Socioeconomic Factors:
Poverty, limited access to healthcare, lack of health education, and poor nutritional awareness play a critical role in the persistence of high anemia rates among women in low- and middle-income countries.
Health and Social Consequences
The impact of anemia extends beyond individual health to broader social and economic consequences.
Health consequences include:
- Chronic fatigue and general weakness: reducing a woman’s ability to work and maintain daily productivity
- Impaired cognitive function: affecting concentration, memory, and overall brain performance
- Reduced immunity: increasing susceptibility to infections and illnesses
- Pregnancy and childbirth complications: increasing risks of maternal and infant mortality and poor neonatal outcomes
- Intergenerational impact: anemic mothers often give birth to infants with low iron stores, perpetuating the cycle of poor health and poverty
Prevention and Intervention Strategies
To address this global health challenge, the International Health Organization calls for a set of effective and integrated interventions, including:
1. Preventive and Therapeutic Supplementation:
Providing regular iron and folic acid supplements to women of reproductive age, pregnant women, and adolescents as part of comprehensive primary healthcare programs.
2. Nutritional Interventions:
Promoting dietary diversification and food fortification (e.g., enriching flour with iron and folic acid), alongside raising awareness about consuming iron-rich foods such as spinach, lentils, and meat, combined with vitamin C to enhance absorption.
3. Control of Infections and Diseases:
Implementing effective programs to combat malaria and eliminate intestinal parasites in endemic areas, along with improving sanitation and hygiene services.
4. Strengthening Primary Healthcare:
Training healthcare workers to detect anemia early using portable hemoglobin measurement devices, provide nutritional counseling, and manage severe cases appropriately.
5. Empowerment of Women and Girls:
Investing in girls’ education, delaying early marriage and childbirth, and improving women’s socioeconomic status—all of which positively impact their health and access to resources.
The International Health Organization plays a pivotal role in addressing anemia in women, recognizing it not merely as a transient health condition, but as an indicator of deeper gaps in nutrition systems, healthcare access, and social equity. The organization supports countries in developing appropriate health policies, strengthening nutrition programs, providing scientific guidance, and building health system capacity. It also promotes collaboration between governments, international organizations, and civil society to ensure sustainable investment in public health programs and achieve health equity for women worldwide.
