    <r:Abstract>
      <r:Content xml:lang="sv">H70 är en av de longitudinella studierna från Göteborg där representativa populationer av äldre har följts över lång tid (metadata relaterade till H85, 95+ och Kvinnoundersökningen finns via fliken Relaterade studier). 
H70-undersökningen är en populationsbaserad studie av åldrande hos 70-åringar, som både fokuserar på medicinska och kognitiva mått. 
De undersökningsmetoder som använts har varit samma för samtliga studier, och för att resultaten ska kunna jämföras över tid har uppföljningarna varit så identiska som möjligt. Undersökningen omfattar psykiatrisk intervju, somatiska undersökningar, tester av sjukgymnast, psykologtest, blodprov med omfattande laboratorieanalyser samt anhörigintervju. Vidare samlas data in relaterad till socioekonomisk status, civilstånd, levnadsvillkor, bostadssituation, utbildning, religiositet, hobbys och livshändelser. Slutligen ingår neurobiologisk undersökning i form av datortomografi (CT) och magnetröntgen (MR) av hjärnan samt lumbalpunktion och analys av hjärn-ryggmärgsvätska. Journaler från alla större sjukhus, geriatriska och psykiatriska institutioner samt polikliniska mottagningar i Göteborg granskas för att finna fall av psykiska och somatiska sjukdomar. Demens, depression, psykotiska sjukdomar, sömnproblem, ångestsjukdomar, och post-traumatiskt stresssyndrom (PTSS) diagnostiseras enligt DSM-III-R och DSM-IV. Somatiska sjukdomar klassificeras enligt etablerade kriterier.

Syfte:

Det ursprungliga syftet var:
1. Att bidra med kunskap om det normala åldrandet och om normala förhållanden i åldersgruppen
2. Att göra en undersökning av sociala och medicinska förhållanden i populationen
3. Att generera data för planering av äldrevård
4. Att erbjuda deltagarna en grundlig medicinsk undersökning

Vid baslinjemätningens hälsoundersökning år 1976/77 deltog 1036 individer (474 män och 562 kvinnor) vilket motsvarade en svarsfrekvens på totalt 81 %. Deltagarna har följts upp vid 75-, 79-, och 95 års ålder. Studiens undersökningar har genomförts år 1976, 1981, 1985 och 2001.

Undersökningen omfattar psykiatrisk intervju, somatiska undersökningar, tester av sjukgymnast, psykologtest, blodprov med omfattande laboratorieanalyser samt anhörigintervju. Vidare samlas data in relaterad till socioekonomisk status, civilstånd, levnadsvillkor, bostadssituation, utbildning, religiositet, hobbys och livshändelser.

      <r:Content xml:lang="en">H70 is one of the longitudinal population studies from Gothenburg where representative study samples of older adults have been followed over a long period of time (metadata related to the H85, 95+ and Prospective Population Study of Women studies can be found under the Related studies tab).
H70 is a population-based study of aging in 70-year-old populations which focuses on both medical and cognitive measures.
The examination procedures at each study have been retained as identical as possible to provide results that can be compared over time. The study comprises a psychiatric interview, physical examination, psychological tests, blood samples with extensive laboratory analysis and a close informant interview. It also includes collecting data related to socioeconomic status, marital status, living conditions, housing situation, education, religion, hobbies and life events. Neurobiological investigations in the form of computed tomography (CT) and magnetic resonance imaging (MRI) of the brain and spinal puncture and analysis of brain-spinal fluid are also carried out. Medical records from all major hospitals, geriatric and psychiatric institutions and outpatient clinics in Gothenburg are evaluated to find cases of psychiatric and somatic diseases. Dementia, depression, psychotic disorders, sleep disorders, anxiety disorders, and post-traumatic stress disorder (PTSD) are diagnosed according to DSM-III-R and DSM-IV. Somatic diseases are classified according to established criteria.

Purpose:

The original aim was:
1. To contribute to the knowledge of normal ageing processes and of normal conditions within the age group
2. To make a survey of the social and medical conditions of the population.
3. To obtain basic data for planning the care of the older adults
4. To offer the subjects a thorough medical examination

At the 1976-77 baseline health examination 1036 individuals participated (474 men and 562 women), which represents a response rate of 81% in total. Participants were followed up at 75, 79, and 95 years of age. The study surveys have been conducted in 1976, 1981, 1985 and 2001.
