Histories of depression-related symptoms were obtained from 3845 randomly selected adult residents of Kansas City, Missouri, and Washington County, Maryland. Depressed persons were slightly more common in Kansas City than in Washington County but within the latter area no urban-rural differences were observed. More depressed persons were found among blacks than among whites. Slightly more white females than males were depressed; no significant differences were found between black females and males. After adjustment for the effects of other independent variables, the probability of having symptoms of depression was highest among persons who were young adults, unmarried, not employed outside the home, poorly paid, and not well educated.
研究人员从密苏里州堪萨斯城和马里兰州华盛顿县随机抽取了3845名成年居民，获取了他们与抑郁相关症状的病史。堪萨斯城的抑郁症患者比华盛顿县略多，但在华盛顿县内未观察到城乡差异。黑人中的抑郁症患者比白人更多。抑郁的白人女性略多于男性；黑人女性和男性之间未发现显著差异。在对其他自变量的影响进行调整后，出现抑郁症状可能性最高的人群是年轻成年人、未婚、不在家工作、收入低且受教育程度不高的人。
