In this study, minor depression has been significantly associated with lower life satisfaction and worse indexes of life quality. The results supported the current concept that minor depression is prevalent in later life, especially among the oldest-old. Subjects with minor depression had worse self-reported opinions about memory and sleep patterns, but when these variables were objectively measured, no meaningful differences could be determined by the research team. Female gender and the concurring presence of generalized anxiety disorder were both significantly associated with the presence of minor depression diagnosis.
