OBJECTIVES To determine the prevalence of disabling and non-disabling back pain across age in older adults, and identify risk factors for back pain onset in this age group. METHODS Participants aged ≥ 75 years answered interviewer-administered questions on back pain as part of a prospective cohort study [Cambridge City over-75s Cohort Study (CC75C)].(More)
Key neuropathological changes associated with late-onset dementia are not fully understood. Population-based longitudinal studies offer an opportunity to step back and examine which pathological indices best link to clinical state. CC75C is a longitudinal study of the population aged 75 and over at baseline in Cambridge, UK. We report on the first 213(More)
BACKGROUND Many studies have considered the prevalence of dementia in mainland China, Hong Kong and Taiwan. However, area level estimates have not been produced. This study examines area differences across mainland China, Hong Kong and Taiwan adjusting for the effect of methodological factors with the aim of producing estimates of the numbers of people with(More)
This study explores emerging lexical processes that may be the foundation for children's acquisition of morphological knowledge and the relation of these processes to reading comprehension. First and third graders were given two tasks involving lexical analysis of morphologically complex words. Two years later, they were given a measure of processing(More)
OBJECTIVE There have been dramatic societal changes in East Asia over the last hundred years. Several of the established risk factors could have important period and cohort effects. This study explores temporal variation of dementia prevalence in mainland China, Hong Kong and Taiwan taking study methods into account. METHODS Seventy prevalence studies of(More)
BACKGROUND Deaths are rising fastest among the oldest old but data on their transitions in place of care at the end of life are scarce. AIM To examine the place of residence or care of > or =85 year-olds less than a year before death, and their place of death, and to map individual changes between the two. DESIGN OF STUDY Population-based cohort study.(More)
BACKGROUND The "oldest old" are now the fastest growing section of most western populations, yet there are scarcely any data concerning even the common problem of falls amongst the very old. Prospective data collection is encouraged as the most reliable method for researching older people's falls, though in clinical practice guidelines advise taking a(More)
BACKGROUND Despite fast-growing 'older old' populations, 'place of care' trajectories for very old people approaching death with or without dementia are poorly described and understood. AIM To explore end-of-life transitions of 'older old' people across the cognitive spectrum. DESIGN Population-based prospective cohort (United Kingdom) followed to(More)
