Aim: The aim of this study was to evaluate depression at 6 and 12 months postpartum, using the Edinburgh Postpartum Depression Scale (EPDS) total score and its subitem regarding self-harm ideation (SHI) at 1 month postpartum.
Methods: A sample of 12,358 postpartum women answered the EPDS and questionaries at 1, 6, and 12 months postpartum longitudinally.
Results: For participants with postpartum depression (PPD; EPDS total score ≥9) and SHI (SHI sub-score ≥1) at 1 month postpartum, the risk of depression at 6 and 12 months postpartum (odds ratio [95% confidence interval] at 6 and 12 months postpartum: 20.
Objectives: To examine the effect of social support on the risk of caregiver's functional disability due to spouse's functional disability.
Design: Longitudinal study.
Setting And Participants: In this cohort study using the Ohsaki Cohort 2006 Study data, the baseline survey was conducted from December 1, 2006, to December 15, 2006, and included 7598 older adults, including 3799 couples, ≥65 years of age.
Background: Chronic kidney disease (CKD) contributes to decreased life expectancy. We examined the association between leisure-time physical activity (LTPA), non-leisure-time physical activity (non-LTPA) and kidney function.
Methods: This was a cross-sectional study including 32 162 community-dwelling adults aged ≥ 20 years from the Tohoku Medical MegaBank community-based cohort study.
Article Synopsis
- - The study aimed to explore how genetic risk, healthy lifestyle habits, and susceptibility to hyperuricaemia (high uric acid levels) are interconnected in a group of over 7,200 participants aged 20 and above.
- - Results showed that 3% of participants developed hyperuricaemia over 3.5 years, with those having both high genetic risk and poor lifestyle choices significantly more likely to develop the condition (odds ratio: 5.34).
- - The findings suggest that maintaining a healthy lifestyle can lower the risk of hyperuricaemia despite genetic predispositions, indicating that both genetic and lifestyle factors are important for identifying individuals at risk.
Few population-based studies including younger adults have examined the potential of olfactory function tests to capture the degree of atrophy in memory-associated brain regions, which cannot be adequately explained by cognitive function tests screening for cognitive impairment. This population-based study investigated associations between high-resolution olfactory test data with few odours and grey matter volumes (GMVs) of the left and right hippocampi, amygdala, parahippocampi, and olfactory cortex, while accounting for differences in cognitive decline, in 1444 participants (aged 31-91 years). Regression analyses included intracranial volume (ICV)-normalised GMVs of eight memory-related regions as objective variables and age, sex, education duration, smoking history, olfaction test score, and the Montreal Cognitive Assessment-Japanese version (MoCA-J) score as explanatory variables.
