Self-harm and suicide remain prevalent in later life. For younger adults, work has highlighted an association between higher early-life cognitive ability and lower self-harm and suicide risk. Comparatively little is known about its association with self-harm and suicide among older adults. Furthermore, most work has measured cognitive ability in ea...

Background Homelessness encompasses a wide spectrum of experience. Rough sleepers and people attending homeless shelters have been found to be at an increased risk of mortality. It is unclear whether risks are also elevated in those squatting, living temporarily in low-cost hotels or ‘sofa-surfing’ with friends or family members. This study examine...

Background: The onset of psychological distress most commonly occurs in adolescence and, in keeping with other exposures, is time-varying across the life course. Most studies of its association with mortality risk are, however, conducted in middle- and older-aged populations with a single baseline assessment of this characteristic. This may lead t...
