Introduction:
- A study conducted across eight states in India involving 4,613 participants revealed that the prevalence of anemia has been overestimated by previous surveys.
- The study, led by Dr. Anura Kurpad from St. John’s Medical College, Bengaluru, utilized venous blood instead of capillary blood to measure hemoglobin and iron status.
Methodology:
- Previous surveys, including the National Family Health Surveys (NFHS), measured hemoglobin using finger-prick-based capillary blood.
- The latest study used venous blood, providing a more accurate measurement of hemoglobin levels and iron status through ferritin.
- Capillary blood hemoglobin measurements tend to underestimate the true value due to a phenomenon called plasma-skimming, leading to dilution and lower hemoglobin values.
Prevalence of Anemia:
- The study found that the prevalence of anemia was predominantly of the mild variety.
- Overall, 18.4% of the entire sample were mildly anemic, 14.7% were moderately anemic, and 1.8% were severely anemic.
- Women had a higher prevalence of anemia compared to men, with moderate anemia being significantly higher in women (22%) compared to men (7.6%).
- Anaemia prevalence varied across different demographics: Adolescent girls, adults, and elderly women had higher prevalence rates compared to their male counterparts.
Comparison with NFHS Surveys:
- The prevalence of anemia was much higher in NFHS surveys that used capillary blood compared to the latest study.
- The discrepancy highlights the importance of using accurate methods for measuring hemoglobin levels to assess the true prevalence of anemia.
Regional Disparities:
- The prevalence of anemia varied across different states, with Assam having the highest prevalence (69.8% overall) and Meghalaya having the lowest (12.1% overall).
Causes of Anemia:
Anemia :
Anemia occurs when the body has too few red blood cells or when these cells lack enough oxygen-carrying capability to meet the body’s physiological requirements. The extent of these needs can differ based on factors such as age, gender, altitude, smoking habits, and whether an individual is pregnant. Steps to Tackle Anemia :
|
- Iron deficiency was found to be a driver of anemia in some cases but not the sole cause.
- Other factors such as vitamin B12 and folate deficiency, inflammation, and dietary factors contribute to the prevalence of anemia.
- The focus on iron deficiency as the main cause of anemia in India may overlook other contributing factors.
Policy Implications:
- The study suggests that policies focused solely on iron supplementation may need to be reconsidered.
- Excess iron intake can lead to oxidative stress and pose risks to overall health.
- Addressing inflammation and promoting dietary diversity may be more effective strategies for combating anemia.
Recommendations:
- Diversifying diets to include millets, which are more resilient to climate change and contain higher amounts of iron and calcium, can help improve overall nutrient intake.
- Policies should focus on reducing inflammation naturally through dietary interventions rather than relying solely on iron supplementation.
Conclusion:
- The study highlights the need for accurate methods of measuring hemoglobin levels to assess the true prevalence of anemia.
- It underscores the importance of addressing multiple factors, including dietary diversity and inflammation, in combating anemia effectively.
- Policy interventions should consider the holistic approach to nutrition and health to address the complex issue of anemia in India.
