To explore the relationship between demographic factors and seasonal changes in mood and behaviour.
A health survey was conducted among 40-45 year old inhabitants in Hordaland County, Norway. The Global Seasonality Score, investigating seasonal symptoms, was given to 4299 men and 9983 women. Response rates among those receiving the questionnaire were 79.8% for men (n = 3432) and 81.2% for women (n = 8223).
High seasonality was reported by 18.4% of men and 22.2% of women. Female gender, low educational level, high level of affective symptomatology and low household income correlated with high seasonality. Among men, being single was also a determinant factor for high seasonality. Reported seasonality also depended on which month the questionnaire was filled in.
In this study, high seasonality was most prevalent among females, being single, having a low annual income and a low education level. The latter two findings are different from expectations which could be drawn from previous studies suggesting an opposite association.
探讨人口统计学因素与情绪和行为季节性变化之间的关系。
对挪威霍达兰郡40 - 45岁的居民进行了一项健康调查。向4299名男性和9983名女性发放了调查季节性症状的全球季节性评分表。男性问卷回复率为79.8%（n = 3432），女性问卷回复率为81.2%（n = 8223）。
18.4%的男性和22.2%的女性报告有高度季节性变化。女性、低教育水平、高情感症状水平和低家庭收入与高度季节性变化相关。在男性中，单身也是高度季节性变化的一个决定因素。报告的季节性变化还取决于填写问卷的月份。
在本研究中，高度季节性变化在女性、单身、年收入低和教育水平低的人群中最为普遍。后两个发现与以往研究得出的相反关联的预期不同。
