      <abstract xml:lang="en">The population study of women in Gothenburg is a population study based at the University of Gothenburg. The study started as a cross-sectional study in 1968 including 1462 women aged 38, 46, 50 and 60 years. The participants have after that been followed-up with regular examinations in 1974-75, 1980-81, 1992-1993, 2000-2001, 2004-2005, 2009-2010 and 2016-2017. In addition, new participants have been included. During the examinations 2004-2005 and 2016-2017, only women 38 and 50 years old were invited to participate with the purpose of enabling comparison of these age cohorts. The study comprises physical and mental disease as well as health, social and psychological circumstances and data regarding food and dental health. To study determinants among middle age women that have importance for the development of cardiovascular disease, diabetes, cancer, dementia and other mental illness in high age is possible because of the long running follow-ups, high participant rates, and thorough mapping of non-participants and data regarding morbidity and mortality. The study covers both longitudinal trends (change in individuals over time) and secular trends (changes in the population over time). This implies the possibility to study e.g. whether the increased consumption of oestrogenic hormones and new antidepressive agents in the population has influenced the occurrence of cardiovascular disease, dementia, depression and the proportion that are under treatment. The long-running follow-up has also made it possible to study the long term prognosis for these diseases and whether the risk for prolonged illness increases with older age. In addition, women from different birth cohorts are examined at certain ages to investigate secular trends in health related variables, such as obesity and dental health. The questionnaires have been changed as little as possible between each survey. Data from 1968 and 1974 are available from SND. The population study of women in Gothenburg collaborates with the H70 study which started in 1971, a cross-sectional study of men and women in Gothenburg aged 70 years. It is coordinated by several researcher groups, especially the groups handling general medicine, epidemiology, psychiatry and geriatrics. When the participants turned 70 years old, they were invited to participate in the H70 study (1992, 2000), and a follow-up examination of 75 years old participants 2005-2006.  Purpose:  The purpose of this study was initially to investigate anemia and health factors related to menopause, but has later also included  examination of determinants among middle age women that have importance for the development of cardiovascular disease, diabetes, cancer, dementia and other mental illness in high age.</abstract><abstract xml:lang="sv">Kvinnoundersökningen i Göteborg är en populationsstudie som bedrivs vid Göteborgs universitet. Studien startade 1968 som en tvärsnittsstudie omfattande 1462 kvinnor i åldrarna 38, 46, 50, 54 och 60 år. Sedan dess har deltagarna genomgått regelbundna uppföljningar 1974-75, 1980-81, 1992-1993, 2000-2001, 2004-2005, 2009-2010 och 2016-2017. Samtidigt har nya deltagare tillkommit. Vid undersökningarna 2004-2005 samt 2016-2017 inbjöds endast kvinnor 38 och 50 år gamla att delta för att möjliggöra en jämförelse av dessa ålderskohorter. Studien omfattar såväl kroppsliga och psykiska sjukdomar, hälsa, sociala och psykologiska faktorer som tand- och kostdata. Att studera faktorer hos kvinnor i medelåldern som har betydelse för utveckling av bland annat hjärtkärlsjukdom, diabetes, cancer, demens och andra psykiska sjukdomar i hög ålder är möjligt i kvinnostudien tack vare en lång uppföljningstid, hög deltagarfrekvens, och noggrann kartläggning av bortfall samt sjukdoms- och dödlighetsdata. Studien ger möjlighet att studera både longitudinella trender (förändring över tid hos individer) och sekulära trender (förändring i befolkningen över tid). Man har bl. a. studerat  huruvida den ökade förbrukningen av östrogena hormoner och nya antidepressiva läkemedel i befolkningen har påverkat förekomsten av hjärtkärlsjukdom, demens och depression samt andelen som har behandling. De långa uppföljningstiderna har också gjort det möjligt att studera långtidsprognosen för dessa sjukdomar och om risken för långvarig sjukdom ökar med stigande ålder. I studien jämförs även kvinnor från olika födelsekohorter vid vissa åldrar för att studera sekulära trender i hälsorelaterade variabler, som exempelvis fetma och tandhälsa. Frågorna i enkäterna har i så så liten grad som möjligt ändrats mellan varje undersökningsomgång. Data från undersökningen 1968 och 1974 finns hos SND. Kvinnoundersökningen samarbetar med H70-studien som startade 1971, en studie av manliga och kvinnliga 70-åringar i Göteborg och koordineras av flera forskargrupper, framför allt inom allmänmedicin, epidemiologi, psykiatri och geriatrik. Kvinnor i Kvinnoundersökningen erbjöds de åren de fyllde 70 år att delta i H70-studien (1992, 2000) samt till en uppföljning av 75-åringar som genomfördes 2005-2006.  Syfte:  Syftet med studien var från början att undersöka anemi och hälsofaktorer relaterad till menopaus, men har sedan omfattat även att undersöka faktorer hos kvinnor i medelåldern som har betydelse för utveckling av bland annat hjärtkärlsjukdom, diabetes, cancer, demens och andra psykiska sjukdomar i hög ålder.</abstract>

        <sampProc xml:lang="en">Systematic sample based on birth date.  In 1968-1969, a representative sample of 1622 women living in Gothenburg, Sweden, was invited to a free health examination. A total of 1462 women, aged 38, 46, 50, 54, and 60 (90.1%), accepted the invitation and participated in the Prospective Population Study of Women in Gothenburg (PSWG)  In 1980-1981 a follow-up examination was conducted (participation rate 78.9%). Two new age groups, aged 26 and 38 in 1980-1981, were recruited, with the purpose of conducting cross-sectional comparisons over time. Also, women born in 1930, who moved to Gothenburg between 1969 and 1980 and belonged to the same date of birth as the original cohort, were invited to the 1980-1981 examination, which implied that 50-, 38- and 26-year-old women examined in 1980-1981 were representative of the female population in Gothenburg in 1980-1981. Follow-up examinations were also conducted in 1992-1993 (participation rate 70.1%), when two of the cohorts were 38 or 50.  Further follow-up examinations were made in 2004-2005 and 2009-2010.<concept/></sampProc><sampProc xml:lang="sv">Systematiskt urval baserat på födelsedatum.

Även två nya åldersgrupper (26 respektive 38 år) rekryterades 1980-1981 med syfte att undersöka hur tvärsnittet förändras över tid. Även kvinnor födda 1930 och som flyttat till Göteborg mellan 1969 och 1980 och som uppfyllde samma urvalskriterier som den ursprungliga kohorten bjöds in till undersökning.
