We aimed to study the association of childhood urbanicity with depressive symptoms in late adulthood.
DESIGN, SETTING AND PARTICIPANTS: We used linear and logistic regressions to analyse data drawn from 20 400 respondents from the Survey of Health, Ageing and Retirement in Europe, a panel dataset incorporating a representative sample of the 50+ population in 13 European countries.
Childhood urbanicity was determined using self-reports of the respondents' circumstances at age 10, and late-adulthood depression using the EURO-D scale. We conditioned on circumstances early in life as well as later in life, most importantly late-adulthood urbanicity. We estimated the associations using linear regression models and limited dependent variable models.
A pooled regression of both men and women suggested that childhood urbanicity is associated non-monotonically with depression in late adulthood and is particularly apparent for those spending their childhoods in suburban settings. We found that individuals who spend the longest time in their childhood in a suburban home exhibit an average increase in probability of 3.4 (CI 1.1 to 5.7) percentage points in reporting four or more depressive symptoms. The association was robust to the inclusion of a host of household characteristics associated with childhood urbanicity and was independent of current urbanicity and current income. When broken down by gender, we found some evidence of associations between depressive outcomes and urban living for men, and stronger evidence of such associations with urban and suburban living for women who exhibit an increase of 5.6 (CI 2.2 to 9.0) percentage points in reporting four or more depressive symptoms.
Our analysis reveals a relationship between childhood urbanicity and depression in late adulthood. The evidence presented on the nature of this relationship is not straightforward but is broadly suggestive of a link, differing by gender, between greater urbanicity and higher levels of depressive symptoms. The life-long nature of this association may potentially inform policy agendas aimed at improving urban and suburban living conditions.
本研究旨在探讨儿童时期城市化与晚年抑郁症状之间的关联。
设计、地点和参与者:我们使用线性和逻辑回归分析了来自欧洲健康、老龄化和退休调查的 20400 名受访者的数据,该调查是一个面板数据集,包含了 13 个欧洲国家 50 岁以上人群的代表性样本。
童年时期的城市化程度是通过受访者 10 岁时的生活环境自报数据来确定的,晚年抑郁则使用 EURO-D 量表来评估。我们在分析中既考虑了早期生活环境,也考虑了后期生活环境,尤其是晚年的城市化程度。我们使用线性回归模型和受限因变量模型来估计关联。
对男性和女性的综合回归表明,童年时期的城市化程度与晚年的抑郁程度呈非单调关系,特别是在那些童年时期生活在郊区的人群中更为明显。我们发现,那些在童年时期大部分时间生活在郊区家庭中的人,报告出现 4 种或更多抑郁症状的概率平均增加 3.4(95%CI 1.1 至 5.7)个百分点。这种关联在纳入与童年时期城市化程度相关的一系列家庭特征后仍然稳健,且与当前的城市化程度和收入无关。按性别细分后,我们发现男性的抑郁结局与城市生活之间存在一些关联的证据,而女性的关联则更为明显,报告出现 4 种或更多抑郁症状的概率增加了 5.6(95%CI 2.2 至 9.0)个百分点,这种关联与城市和郊区生活有关。
我们的分析揭示了儿童时期城市化程度与晚年抑郁之间的关系。虽然这种关系的性质并不明确,但总体上表明,城市化程度与抑郁症状水平之间存在关联,这种关联因性别而异,在男性中表现为与更高的城市化程度相关,在女性中则表现为与更高的城市化和郊区化程度相关。这种关联的终身性质可能为旨在改善城市和郊区生活条件的政策议程提供信息。
