The aim of this study was to determine the prevalence of seasonal affective disorder (SAD) in Greenlanders and Danes living at four different latitudes in Greenland. A Seasonal Pattern Assessment Questionnaire (SPAQ) was mailed to 6021 men and women between the ages of 18 and 59 years living in four different municipalities in Greenland. The recipients were randomly selected from the National Population Register. Approximately 9% of the respondents met the criteria for SAD, and the incidence of SAD varied between a southern municipality and three northern municipalities. The prevalence of SAD was particularly high in northern municipalities. No significant difference was found in the prevalence of SAD between Greenlanders and Danes. The results are comparable with other population studies that have reported a high prevalence of SAD in arctic areas. The clinical implications of our findings and the possibilities for introducing light therapy should be assessed in future studies.
本研究的目的是确定居住在格陵兰四个不同纬度地区的格陵兰人和丹麦人的季节性情感障碍（SAD）患病率。一份季节性模式评估问卷（SPAQ）被邮寄给居住在格陵兰四个不同自治市的6021名年龄在18至59岁之间的男性和女性。收件人是从国家人口登记册中随机挑选出来的。约9%的受访者符合SAD标准，且SAD发病率在一个南部自治市和三个北部自治市之间存在差异。SAD患病率在北部自治市尤其高。在格陵兰人和丹麦人之间，SAD患病率未发现显著差异。这些结果与其他报道北极地区SAD患病率较高的人群研究结果具有可比性。我们研究结果的临床意义以及引入光疗法的可能性应在未来研究中进行评估。
