**Question:** Not included in Infant mortality rate: March 2012

**Core Concept:** Infant mortality rate (IMR) is a measure of child health and wellbeing in a population. It is calculated as the number of deaths per 1,000 live births. IMR is an important indicator of the effectiveness of public health interventions and healthcare systems.

**Why the Correct Answer is Right:** The correct answer represents a factor that is not included in the calculation of the infant mortality rate. In March 2012, the World Health Organization (WHO) introduced the concept of "Exclusive Breastfeeding" (EBF) as one of the key components of the "Global Strategy for Infant and Young Child Feeding." EBF refers to providing breast milk as the sole source of nutrition for infants up to 6 months of age, with continuation of breastfeeding along with appropriate complementary foods until 2 years of age or beyond. This is a crucial aspect of infant health, but it is not directly incorporated into the calculation of IMR.

**Why Each Wrong Option is Incorrect:**

A. **Cardiovascular diseases (CVD)**: While CVD is a significant cause of mortality in adults, it is not relevant to the calculation of infant mortality rate. Infant mortality is mainly influenced by factors such as infectious diseases, prematurity, and congenital anomalies.

B. **Neurodevelopmental disorders**: These conditions affect children and adolescents, not infants. Inclusion of such disorders would not impact the calculation of infant mortality rate, which focuses on early-life causes of death.

C. **HIV/AIDS**: HIV/AIDS is a disease affecting adults and adolescents, and the infant mortality rate focuses on infant mortality. Including HIV/AIDS would not influence the calculation of infant mortality rate.

D. **Early childhood nutrition**: Although nutrition is crucial for infant health, the focus of the infant mortality rate is on specific causes of death, not general nutritional status. Incorporating early childhood nutrition would broaden the scope beyond the intended measure.

**Clinical Pearl:** Including factors like Cardiovascular diseases, Neurodevelopmental disorders, HIV/AIDS, and Early childhood nutrition does not directly impact the calculation of infant mortality rate, which is centered on infant-specific causes of death and does not consider non-infant health issues.

**Correct Answer Explanation:**

The correct answer is related to the **Global Strategy for Infant and Young Child Feeding** (S IYCF), which highlights the importance of appropriate feeding practices for infants and young children. This strategy emphasizes the provision of breast milk during the first 6 months of life, followed by the introduction of appropriate foods along with continued breastfeeding until 2 years of age or beyond. While the S IYCF is crucial for child nutrition, it does not directly influence the calculation of infant mortality rate, which focuses on infant-specific causes of death. IMR is primarily determined by factors like infectious diseases, prematurity, and congenital anomalies, not nutrition-related issues.

**Core Concept:** The infant mortality rate is a crucial indicator of public health and reflects the burden of infant deaths due to specific causes. It is not
