Abstract ▼ AI-Helper

Objectives: This study investigated sleep quality in female full-time homemakers and evaluated the relationship of sleep disturbance with psychological and socio-environmental factors. Methods: This cross-sectional study adopted a structured survey and sequential recruitment method for randomized participation of community-dwelling full-time female homemakers. Sleep quality and mental health were measured using the Korean version of the Pittsburgh Sleep Quality Index (K-PSQI), Korean version of the Beck Depression Inventory-II (K-BDI-II), Korean version of the Beck Anxiety Inventory (K-BAI), and Korean version of the Beck Hopelessness Scale (K-BHS). The willingness-to-pay (WTP) method was selected to measure the self-evaluated monetary value of household service work. The relationship among the main relevant factors was statistically analyzed through a mediation model. Results: A total of 166 participants were analyzed and classified having poor versus good sleep quality (poor : 24.1%, n = 40 ; good : 75.9%, n = 126 ; cut-off point = 9 on the K-PSQI). Significant between-group differences were observed in mental health status (K-BDI-II, p < 0.001 ; K-BAI, p < 0.001 ; K-BHS, p = 0.003). The moderated mediation model was verified, indicating that depression may mediate the association between nurturing burden and sleep disturbance. The path from nurturing burden to depression may be moderated by average monthly household income. Conclusion: A relatively high portion of full-time female homemakers may suffer from sleep disturbance and interactions between psychological and socio-environmental factors might determine sleep quality, suggesting the need for public health policies targeting improvement of sleep quality and mental health among full-time homemakers.

그림 Figure 1. Basic hypothesis in this study. The hypothesis is simplified as follows : monthly income may moderate the association between the burdens of nurturing and depression and then depression may mediate the association between the burdens of nurturing and sleep disturbance.
그림 Figure 2. Between-group differences in the distribution of the severity on each scale of depression (K-BDIII), anxiety (K-BAI), and hopelessness (K-BHS). The histograms in the figure show that as well as the normal level, all the severity levels on each scale were appearing in each group. The proportion of all severity levels was higher in poor sleep quality group than in good sleep quality group. The significant differences were manifested on KBDI- II scale for depression level and on K-BAI scale for anxiety level. * : Indicates p ＜ 0.01. K-BAI : Korean version of Beck Anxiety Inventory, K-BHS : Korean version of Beck Hopelessness Scale, K-BDI-II : Korean versions of Beck Depression Inventory-II.

그림 Figure 3. The association between the burden of nurturing and depression by the level of household average monthly income. The positive association of the burden of nurturing and depression was stronger among lower level of household average monthly income than among higher level. Low, intermediate and high household average monthly income indicates 2 million, 3 million, 4 million in KRW, respectively.
