Over 70% of the adult population of five rural communities in Northern Norway participated in a three-part epidemiological study that included identical questions on mental health. Data were collected in 1987/88, 1990 and 1993. Both repeated cross-sectional analyses and individual growth curve analyses on the 2,486 individuals who participated in either two or three surveys were carried out in order to reveal the changes in mental health over time. The proportion of the population using sleeping pills or psychotropic drugs decreased significantly as time progressed. There were also a significant decrease in the proportion of people who reported being depressed or dissatisfied with life, or who had insomnia or problems in coping. A similar improvement in mental health was noted for both sexes and it remained statistically significant even after adjusting for age and level of education. There was no decrease in the proportion of individuals who reported loneliness. The time effect remained significant, even after adjusting for multiple factors in the growth curve analyses. Improvement in mental health has occurred despite the crisis in the region's fishing industry.
挪威北部五个农村社区超过70%的成年人口参与了一项分为三个部分的流行病学研究，该研究包含关于心理健康的相同问题。数据于1987/1988年、1990年和1993年收集。对参与了两次或三次调查的2486名个体进行了重复横断面分析和个体生长曲线分析，以揭示心理健康随时间的变化。随着时间的推移，使用安眠药或精神药物的人口比例显著下降。报告感到抑郁或对生活不满意、或有失眠或应对问题的人的比例也显著下降。男女的心理健康都有类似改善，即使在调整年龄和教育水平后，这种改善在统计学上仍然显著。报告感到孤独的个体比例没有下降。即使在生长曲线分析中调整了多个因素后，时间效应仍然显著。尽管该地区渔业出现危机，但心理健康仍有改善。
