Which of the following is a recognized risk factor for acute otitis media in children?

• A. Daycare attendance
• B. Pacifier use
• C. Bottle feeding
• D. Breastfeeding

Answer: (C)

The main idea is that acute otitis media in children is more likely when the Eustachian tube is not draining properly and bacteria or viruses reach the middle ear. In young kids, the Eustachian tube is shorter and more horizontal, so it’s easier for pathogens from the nasopharynx to travel into the middle ear, especially after a viral upper respiratory infection. Bottle feeding contributes to this risk for a couple of reasons. Feeding from a bottle, particularly in a lying or semi-reclined position, can allow milk to pool toward the throat and nasopharynx, increasing the chance that secretions reach or affect the Eustachian tube. Swallowing is also less frequent when a bottle is propped, which reduces the normal clearance of secretions from the middle ear. In contrast, breastfeeding tends to be protective because breast milk provides antibodies and promotes more favorable swallowing patterns and clearance. Daycare attendance does raise risk due to higher exposure to infectious agents, and pacifier use has some association with increased risk in certain studies, but among the options given, bottle feeding is the recognized modifiable risk factor that directly influences the likelihood of developing acute otitis media.
