    <r:Abstract>
      <r:Content xml:lang="sv">Den epidemiologiska studien "1913 års män" påbörjades 1963. En tredjedel av alla manliga femtioåriga göteborgare kallades till en hälsoundersökning med fokus på hjärt-kärlhälsa. 973 män bjöds in, av dessa deltog 855 i studien (88%). Männen födda 1913 har undersökts när de var 50, 54, 60, 67, 75 och 80 år. Kliniska undersökningar har genomförts varje gång  och vid varje undersökning har också ett antal enkäter ingått. Ett flertal variabler har undersökts genom åren, som BMI, rökvanor, kolesterol, motionsvanor, blodtryck etc. Vart tionde år har sedan studien fyllts på med nya femtioåringar, och sedan 2003 ingår även kvinnor i studien.  
I 1973 var 10% av alla män födda i 1923 inbjudna, varav 77% deltog (226 deltagare). I 1983 och 1993 blev ett slumpmässigt urval på hälften av alla män i Göteborg födda 1933 och 1943 inbjudna, 776 (76%) respektive 798 (55%) deltog. I 2003 var ett slumpmässigt urval på en tredjedel av alla kvinnor (n = 994) och män (n =993) i Göteborg födda 1953 inbjudna. Deltagarfrekvensen var 60% bland männen och 67% bland kvinnorna.
Av de 855 män som ingick i studien från början överlevde 111 (13%) till 90 års ålder.
1913 års män och deras efterföljare, män födda 1923, 1933, 1943 och 1953 är ett exempel på våra traditionella göteborgsstudier. Dessa studier ger möjligheter att utforska hur levnadsbetingelserna har ändrats över fyra decennier och vilka hälsoeffekter dessa förändringar har haft. Från starten på 60-talet har dessa data gett möjligheter att undersöka trender, såväl som i tvärsnitt som longitudinellt. Studierna har resulterat i över 400 vetenskapliga artiklar och 12 avhandlingar.

Syfte:

Att undersöka koronara riskfaktorer och utveckling av kranskärlssjukdom i en grupp svenska urbana män i samma ålder: 50 år. Till undersökningen 2003 inviterades även 50-åriga kvinnor.

1943 års män: 798 deltagare, svarsfrekvens 55%. 1913 års mäns söner: 263 deltagare, svarsfrekvens 56%.</r:Content>
      <r:Content xml:lang="en">Starting in 1963 and with 10-year intervals, five population samples of men aged 50 and living in the city of Gothenborg, Sweden, were examined with respect to cardiovascular risk factors.  In 1963, 973 men were invited. 855 of these took part in the study (88%). Clinical examinations were conducted at baseline and thereafter at 54 (1967), 60 (1973), 67 (1980), 75 (1988) and 80 years of age (1993). At every examination a number of questionnaires were filled in. For the 1973 study, 10% of all men born in 1923 were invited, providing a sample of 292, of which 226 (77%) participated. For the 1983 and 1993 studies, a random sample of half of all men in the city born in 1933 and 1943 were invited; 776 (76%) and 798 (55%), respectively, participated. In 2003 random third of all men (n =993) and women (n = 994) born in 1953 were invited. Participation rate was 60% among the men and 67% among the women.  The study of men born in 1913 and their successors, men born in 1923, 1933, 1943 and 1953 provide opportunities to explore how living conditions have changed over four decades and what health effects these changes have had. From the start of the 60th century, the data have given opportunities to explore trends, as well as in cross-section as longitudinally. The studies have generated 12 thesis and more than 400 scientific papers.

Purpose:

To investigate coronary risk factors and the development of coronary disease in a group of Swedish urban men in the same age: 50 years. To the sampling in 2003 also women were invited.</r:Content>
