ULSAM is a unique, ongoing, longitudinal, epidemiologic study based on all available men, born between 1920 and 1924, in Uppsala County, Sweden. The men were investigated at the ages of 50, 60, 70, 77, 82 88 and 93 years. The reinvestigations in ULSAM were based on the previous investigations. Full screening and official registry data is available in our databases and more data is continuously added.

Health examination at 93 years of age was carried out between December 2013 and March 2015. To this examination 245 men have been invited. Totally 147 men (60%) participated in the investigation. Of these, 23 men were examined at the hospital and 102 were visited at home by a nurse. In addition, 22 men completed only a questionnaire. To this examination even spouses were invited. In the complete examination 43 spouses have participated and 11 completed only a questionnaire.

The Concord Health and Ageing in Men Project (CHAMP) is one of the world’s largest and most comprehensive study of the health of older men ever conducted anywhere in the world. CHAMP involves 1705 men aged 70 years and older recruited from the community living near Concord Hospital in Sydney’s inner west. Subjects were recruited during 2005 and 2006 and subjects were re-assessed after two, five and nine years. A 14 year follow-up assessment (wave 5) is planned for 2019. Clinical dementia assessment was done at baseline but not in waves 2, 3, and 4. Clinical dementia assessment will be included in wave 5.

The study is particularly concerned with cognitive impairment and dementia; falls, fractures and osteoporosis; and urinary problems.

The original aim of the Metropolit cohort was to follow men from early school age to early mid-life, to explore intergenerational mobility and differential life-chances. In 2001 the cohort was revitalised in order to study the development of chronic diseases in a life course perspective.
The Metropolit cohort comprises all 11532 men born in 1953 in the Copenhagen Metropolitan area who were living in Denmark in 1968. These men have been followed repeatedly since their birth. In brief, we have data from birth certificates (1953) which include information on birth dimensions and father’s occupation. In 1965, 7,987 participated in a school-based survey and completed tests of cognition and enquiries regarding leisure-time activities and social aspirations. Data from draft board examinations at around age 19 have been collected for 11,108 of the men. These data include cognitive testing and health information. In 2004, 6,292 of the men responded to a mailed questionnaire with questions on health and lifestyle. In 2009-2010, 2486 of 7799 eligible cohort members participated in the Copenhagen Ageing Midlife Biobank (CAMB) study which comprised questionnaires, cognitive and physical testing as well as blood sampling. Further, around 300 men selected on their young adult and current cognitive performance have been through a neurophysiological examination including EEG, MRI, fMRI and sleep tests. The cohort has also been followed in nation-wide social and health registers for social life, medical and mental hospital diagnosis as well as cause of death from 1969 to 2016.

This is the largest multi-centre study of ageing in men in the world and intends to identify the nature and frequency of some of the symptoms of ageing in men, the relationships between these symptoms to hormonal changes and other risk factors.

In total, 3369 men in 8 different countries in Europe are taking part in the study. These 8 centres are Manchester – UK, Malmo – Sweden, Tartu – Estonia, Lodz – Poland, Szeged – Hungary, Florence – Italy, Santiago de Compostela – Spain, Leuven – Belgium. In each centre, ~400 men aged between 40 and 79 years at the start of the study have been recruited. They will be followed up to look for future changes in their hormonal and general health status. The men will be investigated initially on two occasions, at the start and then ~5 years later. It is highly likely that the study will continue beyond 5 years and further testing will be organised subsequently. The aims of the study are to:

  1. Document geographical variations in the ageing-related involution decline of endocrine function in European men;
  2. Explain the variability in the rate of secular decline in endocrine functions on the basis of socio-demographic, lifestyle, co-morbid, ethnic/racial, or genetic factors;
  3. Predict the physical and psychological health status of individuals based on the variation in ageing-related endocrine decline and changes in body composition.

The initial aims were to examine the importance of lipids, haemostatic factors, and hormones such as testosterone, cortisol and insulin (Lichtenstein et al 1987) in the development of ischaemic heart disease (IHD). Subsequently, other hypotheses were included with a specific interest in platelet function, and psychosocial variables. With the ageing of the cohort, additional outcomes have been included in particular stroke, hearing problems and cognitive function.

The initial design attempted to contact all men aged 45 to 59 years from the town of Caerphilly and adjoining villages. 2512 subjects (response rate 89%) identified from the electoral register and general practice lists were examined between July 1979 until September 1983 (phase I).

Men were initially seen at an evening clinic, where they completed a questionnaire, had anthropometric measures and an ECG taken. They also completed a food frequency questionnaire at home (Fehily et al 1994). They subsequently re-attended an early morning clinic to have fasting blood samples for a wide variety of tests.
Quality control was examined by the use of both “blind” split samples as well as a second repeat measure on a random sub-sample to examine intra-individual variation.

The men have been followed up 5 times; Phase II (July 1984-June 1988), Phase III (Nov 1989-Sep 1993), Phase IV (Oct 1993-Feb 1997) and two further occasions via post. An additional 447 men were included in the survey at Phase II.

The British Regional Heart Study (BRHS) is a prospective study in middle-aged men drawn from general practices in 24 British towns, 7,735 men were recruited in 1978-1980. It was set up to determine the factors responsible for the considerable variation in coronary heart disease, hypertension and stroke in Great Britain. It also seeks to determine the causes of these conditions in order to provide a rational basis for recommendations towards their prevention.

Following the collection of baseline date in 1978-80 the cohort has been followed up through the participants, two-yearly GP Record Reviews, and the Office of Population and Census Surveys. Participants have been re-contacted through questionnaires or assessment in 1983-85, 1992, 1996, 1998-2000, 2003, 2005, 2007 and 2010-2012, 2014, 2015, 2016.
