Hemoglobinemia is primarily a concern in which demographic?

Hemoglobinemia is particularly concerning in infants, primarily due to their physiological characteristics and susceptibility to certain conditions. In infants, especially those under six months of age, the risk of developing hemoglobinemia can be linked to exposure to high levels of nitrates, often found in contaminated drinking water. This condition can lead to a decrease in oxygen-carrying capacity in the blood, commonly referred to as "blue baby syndrome".

Infants have a different hemoglobin makeup and are more vulnerable to the effects of low oxygen levels; their bodies are still developing the necessary systems to manage blood components effectively. Consequently, monitoring the hemoglobin levels in infants, especially in areas where nitrate contamination is a risk, is crucial for preventing serious health issues.

Other demographics, while they can experience hemoglobinemia under specific circumstances, do not face the same level of risk or health impact as infants do in this context. Therefore, the focus on infants as the primary demographic of concern is accurately reflected in the answer provided.
