According to WHO cut off level for haemoglobin in child for anemia is?
**Core Concept**
The World Health Organization (WHO) defines anemia in children based on their haemoglobin (Hb) levels, taking into account age, sex, and other factors. This definition is crucial for identifying and managing anemia in pediatric populations.
**Why the Correct Answer is Right**
The WHO cut-off levels for Hb in children are as follows:
- For children aged 6-59 months, the cut-off is < 110 g/L for boys and < 110 g/L for girls.
- For children aged 5-11 years, the cut-off is < 115 g/L for boys and < 120 g/L for girls.
- For children aged 12-14 years, the cut-off is < 120 g/L for boys and < 120 g/L for girls.
These cut-offs are used to diagnose anemia, as Hb levels below these thresholds indicate a higher risk of anemia.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because the WHO cut-off levels for Hb in children are age- and sex-specific, and the values provided do not match the recommended cut-offs.
**Option B:** This option is incorrect because it does not specify the correct age range or sex for the Hb cut-off.
**Option C:** This option is incorrect because it provides a cut-off value that is too low for the specified age range.
**Clinical Pearl / High-Yield Fact**
When evaluating a child for anemia, it is essential to consider their age, sex, and other factors, as the WHO cut-off levels for Hb can vary depending on these factors.
**Correct Answer: D.**
