Ireland shares with other developed countries the prospect of rapid and sustained population ageing. The age distribution of the Irish population is undergoing a dramatic change at present and this trend is predicted to continue into the future. People are living longer, and older persons represent a larger proportion of the population. In Ireland, the(More)
BACKGROUND Depression is a risk factor for Cardiovascular Disease (CVD). It has been reported that somatic symptoms of depression and not cognitive symptoms are associated with increased risk although findings have been inconsistent. Few studies have examined whether co-morbid anxiety confers additive risk. METHODS We conducted a cross sectional analysis(More)

DESIGN Data were obtained from Wave 1 of The Irish Longitudinal Study on Ageing (TILDA), a population-based study assessing health, economic, and social aspects of aging.

PURPOSE The 3 carotenoids lutein, zeaxanthin, and meso-zeaxanthin, which account for the 'yellow spot' at the macula and which are referred to as macular pigment (MP), are believed to play a role in visual function and protect against age-related macular degeneration (AMD) via their optical and antioxidant properties. This study was undertaken to compare MP(More)
BACKGROUND Fried's definition of frailty is widely used but its measurement is problematic. Timed up-and-go (TUG) is a simple measure of mobility that may be a useful proxy for frailty. Here, we describe the distribution of frailty and TUG in the older population of Ireland and discuss the extent to which TUG identifies the frail and prefrail populations.(More)
Fear of falling (FOF) is associated with poor physical and psychosocial health and can have debilitating consequences especially when it leads to activity restriction. This study examined whether normal and dual task gait disruptions were independently associated with FOF and activity restriction or if they were fully explained by impaired health status.(More)
BACKGROUND some cohort studies of ageing and health supplement questionnaire-based surveys with in-home measurements of biological parameters and others have required respondents to attend assessment centres. Centre-based assessments facilitate detailed measurements and novel technologies, but may differentially influence participation. The aim of this(More)
BACKGROUND Heart rate variability (HRV) is known to be reduced in depression; however, is unclear whether this is a consequence of the disorder or due to antidepressant medication. METHODS We analysed data on 4750 participants from the first wave of The Irish Longitudinal Study on Ageing (TILDA). Time [standard deviation of normal to normal intervals(More)
PURPOSE The purpose of this paper is to measure the rate of satisfaction of the sample population with an emergency department psychiatric service and to explore in open-ended questions, factors which contributed to these satisfaction ratings. DESIGN/METHODOLOGY/APPROACH All psychiatric patients who attended the service and fulfilled the eligibility(More)
OBJECTIVE To examine the effect of age, time of day, the timing of medication and food ingestion on orthostatic blood pressure response (OBP) in community-dwelling adults. METHODS A nationally representative sample of 109 community-dwelling adults aged at least 50 years attended for health assessment in a pilot study of The Irish Longitudinal Study on(More)
