Postpartum women experience various changes in their physical and psychological health and in their relationships with their spouse and newborn. This study aimed to identify and evaluate the factors that affect the quality of life (QoL) of women within six weeks after childbirth. A prospective, cross-sectional correlational study was used. A convenience sample of 179 postpartum women was recruited from four postpartum care centers in South Korea. Participants completed structured questionnaires on postpartum fatigue, postpartum depression, marital intimacy, breastfeeding adaptation, and quality of life. Marital intimacy (β = 0.466, p < 0.001) was the most influencing factor on the QoL of women during the postpartum period. In descending order, postpartum fatigue (β = −0.192, p = 0.001), postpartum depression (β = −0.190, p = 0.001), breastfeeding adaptation (β = 0.163, p = 0.002), and occupation (β = 0.163, p = 0.004) all had a significant influence on QoL (F = 32.09, p < 0.001), and the overall explanatory power was 63.6%. It is necessary to assess and consider the physical, psychological, relational, and demographic factors of women during the early postpartum period. Comprehensive interventions need to be developed to improve the QoL of women during the postpartum period.

We investigated the symptom clusters and effects of symptom clusters on the quality of life of Korean breast cancer survivors. We recruited 241 breast cancer survivors and collected cross‐sectional data on their symptoms. To determine inter‐relationships among symptoms, a principal component analysis with varimax rotation was performed based on the patient’s symptoms (fatigue, nausea/vomiting, pain, dyspnoea, insomnia, appetite loss, constipation, anxiety, depression, systemic therapy side effects, breast symptoms and arm symptoms). The first symptom cluster consisted of psychological (anxiety and depression) and general (appetite loss, fatigue, insomnia and dyspnoea) symptoms, whereas the second symptom cluster consisted of physical (arm symptom, breast symptom, pain and systemic therapy side effects) and gastrointestinal (nausea/vomiting and constipation) symptoms. Subgroup cluster analysis showed that breast cancer survivors with higher‐scoring symptoms had significantly poorer quality of life in both psychological–general symptom cluster and physical–gastrointestinal symptom cluster subgroups, with subgroup‐specific patterns. The symptom clusters differed depending on stage and functional status of breast cancer survivors. Breast cancer survivors may have a specific pattern of symptom clusters. Some symptom clusters may have a negative impact on the quality of life. Identifying symptom clusters of breast cancer survivors may have clinical implications by improving symptom management.
