| Background Sleep disorder is a common health problem for women in the first trimester. Previous studies mainly reflected the overall sleep quality of this group by scale assessment results, which may not accurately capture the differences between various groups of sleep disorders. Objective To explore the potential profiles of women's sleep quality in the first trimester and analyze the physiological, psychological and social factors on different profiles, in order to provide references for the development of personalized sleep intervention measures. Methods A total of 1 066 women in the first trimester of pregnancy who visited the obstetric outpatient clinic of a tertiary hospital in Shenzhen from October 2021 to October 2022 were investigated using the General information questionnaire, Pittsburgh Sleep Quality Index (PSQI), Edinburgh Postnatal Depression Scale (EPDS), Chinese version of short International Physical Activity Questionnaire (IPAQ-S-C) and Social Capital Assessment Tool for in Pregnancy for Maternal Health (SCAT-MH). The sleep profile was identified through latent profile analysis, and the robust three-step method of regression mixture modeling was used to analyse the influencing factors of different sleep profiles. Results The sleep quality of women in the first trimester of pregnancy was divided into three profiles: 732 cases (68.67%) of good sleep quality group, 87 cases (8.16%) of low sleep efficiency group, and 247 cases (23.17%) of daytime dysfunction group. Compared with good sleep quality group, women in the first trimester of pregnancy with younger age (OR=0.951, 95% CI: 0.922~0.980), with an education level of Bachelor's degree and above (OR=1.869, 95% CI: 1.260~2.773) and lower levels of social capital (OR=0.962, 95% CI: 0.951~0.973) were more likely to belong to the low sleep efficiency group. Pregnant women who were older (OR=1.072, 95% CI: 1.027~1.120) and had higher levels of depression (OR=1.166, 95% CI: 1.115~1.218) were more likely to belong to daytime dysfunction group. Pregnant women who were workers (OR=0.507, 95% CI: 0.293~0.876) were less likely to fall into the daytime dysfunction group. Conclusion The sleep quality of women in the first trimester has three latent profiles with significant heterogeneity, and depression and social capital level are the main influencing factors of sleep quality. |
