BACKGROUND It is known that people who suffer from depression are more likely to have other physical illnesses, but the extent of the association between depression and non-psychiatric hospitalisation episodes has never been researched in great depth. We therefore aimed to investigate whether depressed middle-aged and older people were more likely to be(More)
BACKGROUND Half a century after the inception of the term "successful aging (SA)," a consensus definition has not emerged. The current study aims to provide a comprehensive snapshot of operational definitions of SA. METHODS A systematic review across MedLine, PsycInfo, CINAHL, EMBASE, and ISI Web of Knowledge of quantitative operational definitions of SA(More)
BACKGROUND Many of the assessment tools used to study depression among older people are adaptations of instruments developed in other cultural setting. There is a need to validate those instruments in low and middle income countries (LMIC). METHODS A one-phase cross-sectional survey of people aged [greater than or equal to] 65 years from LMIC. EURO-D was(More)
OBJECTIVES This paper aims to systematically review observational studies that have analysed whether depressive symptoms in the community are associated with higher general hospital admissions, longer hospital stays and increased risk of re-admission. METHODS We identified prospective studies that looked at depressive symptoms in the community as a risk(More)
The pathogenesis of frailty and the role of inflammation is poorly understood. We examined the evidence considering the relationship between inflammation and frailty through a systematic review and meta-analysis. A systematic literature search of papers providing data on inflammatory biomarkers and frailty was carried out in major electronic databases from(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)

DESIGN A systematic review of layperson perspectives of SA was conducted across MEDLINE, PsycInfo, CINAHL, EMBASE and(More)
BACKGROUND There is relative little information about the prevalence and risk factors of co-morbid anxiety and depression in later life. These disorders are often associated with worse response to treatment than either condition alone, and researching their epidemiology in diverse settings is vital to policy makers. We therefore investigated the(More)
BACKGROUND Restricted social networks have been associated with higher mortality in several developed countries but there are no studies on this topic from developing countries. This gap exists despite potentially greater dependence on social networks for support and survival due to various barriers to health care and social protection schemes in this(More)
