Investigating the interplay between depression and pregnancy loss: a cross-sectional analysis using NHANES data.

Objective: This study aimed to investigate the association between depressive symptoms and pregnancy losses, as well as the moderating effects of demographic variables, including age, income level and ethnicity.

Methods: Depressive symptoms were assessed using the Patient Health Questionnaire-9 (PHQ-9) questionnaire, with key variables such as "loss of interest," "feeling down," and "sleep disturbances." Weighted linear regression models evaluated the relationship between depressive symptoms and pregnancy losses, while interaction analyses explored the moderating effects of demographic factors.

The risk of chronic kidney disease or proteinuria with long or short sleep duration: a systematic review and meta-analysis of cohort studies.

Objective: Irregular sleep duration has been linked with systemic diseases as well as chronic kidney disease (CKD). However, most of the evidence is low-quality and from cross-sectional data. We hereby present a meta-analysis of cohort studies examining the longitudinal association between short and long sleep with the risk of CKD or proteinuria.
