The Northern Swedish Cohort (NoSCo)

In 1981 a longitudinal study began that includes all pupils who attended or should have attended the last year of compulsory school in the municipality of Luleå. The population consists of 1083 pupils (506 girls and 577 boys) and this group has since been followed by repeated questionnaires, but also through personal meetings, interviews, blood pressure measurements and other Health examinations. The main purpose of the survey was to study the social and medical consequences such as unemployment leads among these young people, who find themselves in the joint between school, training and employment.

The questionnaire consisted of around 90 validated questions regarding social background, work situation, health, family situation, leisure time etc. The questionnaire was almost identical at all investigations. The cohort has been investigated with a comprehensive questionnaire — in 1981 (age 16 years), 1983 (age 18 years), 1986 (age 21 years), 1995 (age 30 years) and 2008 (age 43 years). Clinical measurements were performed in 1981, 1986 and 2008 and interviews were performed with key persons, such as the school nurses in 1981 and with the form teachers in 1981 and 1983. The subsample with early unemployed participants has been followed up with personal interviews since autumn 1981. Until now, they have been interviewed on average four times per person. The main topic has been the health consequences of unemployment.

One of survey results was that unemployment appears to have more serious health consequences for young people than for adults and that health consequences of youth unemployment persists to some extent in adulthood.

Purpose:

Initially, the overall objective of the research programme was to analyse the significance of unemployment in relation to mental health in adolescence for well-being and health status into adult age.

1981年，一项纵向研究（longitudinal study）启动，纳入了吕勒奥市所有已就读或本应就读义务教育最后一年的学生。研究人群包含1083名学生（506名女生和577名男生），此后通过重复问卷、个人会面、访谈、血压测量及其他健康检查对该群体进行随访。本调查的主要目的是研究失业给这些处于学校、培训与就业衔接阶段的年轻人带来的社会及医学后果。

问卷包含约90个经过验证的问题，涉及社会背景、工作状况、健康、家庭情况、休闲时间等。所有调查中使用的问卷几乎完全相同。该队列（cohort）通过全面问卷进行调查的时间点为：1981年（16岁）、1983年（18岁）、1986年（21岁）、1995年（30岁）及2008年（43岁）。临床测量于1981年、1986年和2008年进行，并对关键人员进行访谈，例如1981年访谈校护，1981年及1983年访谈班主任。自1981年秋季起，通过个人访谈对包含早期失业参与者的子样本进行随访。截至目前，每人平均接受四次访谈，主题主要为失业的健康后果。

调查结果之一显示，失业对年轻人的健康后果似乎比成年人更为严重，且青年失业的健康后果在成年期仍在一定程度上持续存在。

**研究目的**：
最初，该研究项目的总体目标是分析青春期失业与心理健康的关联对成年期幸福感及健康状况的意义。
