Final answer:
Mastitis and breast engorgement are more common in primipara women, who are first-time mothers, due to less experience with breastfeeding and their breasts not being as accustomed to lactation.
Step-by-step explanation:
Mastitis and breast engorgement are conditions that can affect breastfeeding women. Mastitis is an inflammation of the breast tissue that can lead to infection, while breast engorgement is the painful overfilling of the breasts with milk. Both conditions are more likely to occur in primipara women, those who are giving birth for the first time. Primiparas may be more susceptible to these conditions because they typically have less experience with breastfeeding techniques and their breasts are not as accustomed to the process of milk production and release as those of multipara women, who have given birth and potentially breastfed before.
