BACKGROUND Lolland-Falster Health Study (LOFUS) was a health examination survey that included self-administered questionnaires, clinical examinations, and the collection of biological samples, undertaken in 2016-2020 in a rural, socioeconomically deprived area with the lowest life expectancy in Denmark. The aim of this study was to examine the determinants of non-participation in LOFUS to evaluate the extent to which LOFUS data reflected the general population of the area. METHODS LOFUS invited randomly selected subjects together with their entire household. As determinants of non-participation, we analyzed age, sex, municipality of residency, citizenship, residency status, socioeconomic status, invitation type, and year of invitation. Relative risk regression was used to estimate the association between determinants and non-participation rate, mutually adjusted for other determinants. RESULTS In total, 53,313 subjects were invited of whom 18,949 (36%) participated. In the multivariable analysis, men had a 3% higher non-participation rate than women; subjects with citizenship other than Danish had a 3% higher non-participation rate than Danes. In-migrants had 6% higher non-participation than long-term residents. Compared with self-supported subjects aged 30-64, both publicly supported subjects of this age and younger and older subjects had higher non-participation rates: 16%, 16%, and 13%, respectively. Compared with self-supported, long-term residents, publicly supported in-migrants had 23% higher non-participation. CONCLUSIONS Only about one third of subjects invited to LOFUS participated. Yet, this is a relatively high participation rate compared with other recent health examination surveys in Denmark. Furthermore, there was a relatively flat social gradient in the non-participation rate across the studied determinants.

丹麦农村地区未参加健康检查调查 - 洛兰-法尔斯特健康研究 (LOFUS) 的结果。

洛兰-法尔斯特健康研究 (LOFUS) 是一项健康检查调查，包括自填问卷、临床检查和生物样本采集，于 2016 年至 2020 年在丹麦预期寿命最低的农村、社会经济贫困地区进行。本研究的目的是检查不参与 LOFUS 的决定因素，以评估 LOFUS 数据反映该地区一般人口的程度。方法 LOFUS 邀请随机选择的受试者及其整个家庭。作为不参与的决定因素，我们分析了年龄、性别、居住城市、公民身份、居住状况、社会经济地位、邀请类型和邀请年份。相对风险回归用于估计决定因素和不参与率之间的关联，并针对其他决定因素进行相互调整。结果 总共邀请了 53,313 名受试者，其中 18,949 名受试者（36%）参与。在多变量分析中，男性的不参与率比女性高 3%；拥有丹麦以外国籍的受试者的不参与率比丹麦人高 3%。外来移民的不参与率比长期居民高 6%。与30-64岁的自费受试者相比，该年龄段的公费受试者以及较年轻和较年长的受试者的不参与率较高：分别为16%、16%和13%。与自养的长期居民相比，公共资助的移民的不参与率高出 23%。结论 受邀参加 LOFUS 的受试者中只有约三分之一参与了。然而，与丹麦最近的其他健康检查调查相比，这是一个相对较高的参与率。此外，在所研究的决定因素中，不参与率存在相对平坦的社会梯度。
