The medical examinations were conducted by a specially trained nurse and a general practice specialist, with the exception of the examinations conducted elsewhere than in Kyllö Health Centre in Jyväskylä. In these examinations, a nurse was not available because of the room arrangement. A nurse was present in 150 medical examinations.
The data are part of the Jyväskylä Longitudinal Study of Personality and Social Development (JYLS), in which the same individuals have been followed over 30 years. At this research stage, data were collected using a life situation questionnaire, an interview, personality tests, self-rating questionnaires, and a medical examination. This dataset contains the medical examinations of 42-year-olds.
The medical examinations consisted of separate sections conducted by a nurse and a physician. The medical checkup conducted by the nurse included the recording of variety of measurements such as height and weight, systolic and diastolic blood pressure, heart rate, and a dementia screening test, which included a category fluency task, a word list learning trial, and a delayed recall test. In the health interview conducted by the physician, the respondents evaluated their health and told about their illnesses, disabilities, and medications. They were also asked how many times they had spent a night in the hospital or seen a physician or a nurse during the past six months. The respondents' physical and psychological symptoms during the past six months were also surveyed, as well as their mental wellbeing and the health of their children, parents, and siblings.
In the clinical examinations, the illness and disability diagnoses were recorded, as well as the year and certainty of the diagnoses. Various activity-limiting symptoms and aberrations were also charted, as well as the need for further treatment. The laboratory tests yielded information about, for example, complete blood count, lipids, blood sugar, plasma levels of total glycosylated hemoglobin, liver function, thyroid gland function, serum dehydroepiandrosterone sulfate, 12-hour urinary norepinephrine and epinephrine, sensitive C-reactive protein, free testosterone of serum, and genes.

This survey is part of the longitudinal study which began in 1968, when the respondents were second-graders (ca. 8 years old) in primary schools in Jyväskylä. The sample consisted of twelve school classes randomly selected from three primary schools. Six of the classes were from the city centre school, and the other six from two suburb schools. There were altogether 369 pupils in the classes.
This wave of data collection began with a letter to the research subjects in November 2000 inviting them to participate in a psychological interview, medical examination, and laboratory tests. The letter also included a Life Situation Questionnaire (LSQ3) and consent forms. 121 men and 120 women participated in the medical examinations included in this dataset. 13 respondents participated only in the medical examination but not in the psychological interview, whereas 15 respondents participated only in the psychological interview but not in the medical examination.
The medical examinations were conducted mainly in the Kyllö Health Centre in Jyväskylä. Some of the examinations were conducted in Tampere, Vantaa, Helsinki, and Lahti. The average duration of the examinations was 1.5 hours.
No systematic reason was found for non-participation. The sample was representative of Finns born in 1959, which is the year when most research subjects were born. Representativeness assessment was based on the data provided by the Statistics Finland. The sample was representative in terms of marital status, household composition, number of children, and employment situation. As regards the education level, the men represented their age group well, but the education level of the women was slightly higher than that of their age group generally.

Data Appraisal and Notes
At this stage, the deceased and those who had refused to participate were no longer part of the sampling frame.
The minimum limit for catecholamine measurements in the clinical laboratory of the University Hospital of Kuopio was set to 0.01 mmol/l. Therefore, the reliability of the values below that limit is not very good. The adrenaline concentration of the urine samples was below 0.01 mmol/l for half of the participants, and hence the 12-hour urinary excretion of adrenaline could not be calculated accurately. Therefore, it is not recommended to use the adrenaline concentrations in analyses.
The information in variables q16_1 and q122_1 - q125_35c has been combined from the medical examination and the psychological interview (N=258). Questions q130 - q133_3m were presented to 17 respondents who did not participate in the medical examination: 15 responded to them during the interview, and 2 were reached by telephone.
