Subclinical depression in Spain: prevalence and health impact

Introduction: Subclinical depression is a prevalent condition with important implications for patients' functioning and wellbeing. However, there is a lack of studies operationalising its definition and studying its clinical significance and health impact in depth. This work analyses subclinical depression impact on a health satus score derived from eight heath domains, and its prevalence in Spanish population.

Methods: The sample was selected from World Health Survey database, choosing the answers for Spain of people with a dignosis of subclinical depression and no depressive disorders.

Results: Controlling the interaction of the different demographic variables, being female was the only significant predictor for the presence of subclinical depression. A worse health status is associated with subclinical depression, being female, a higher age, lower incomes, less years of formal education and being widowed. The decrease is significant in the eight health domains composing the score.

Conclusions: The necessity of a better conceptualization of the nature of clinical depression is highlighted, going in depth in different proposals defending a definition based on clinical signification rather than in the number of depressive symptoms, with the goal of avoiding the pathologization of human suffering and inherent distress to several vital situations.
