En este estudio participaron más de 1.000 mujeres afroamericanas, con bajos ingresos familiares, que habían sido atendidas en clínicas de Baltimore por depresión. Un 13% de ellas tuvieron partos prematuros, mientras que, en las que no sufrían esta patología, el índice de parto prematuro fue del 8%. En la muestra, se incluyó a mujeres de más de 18 años que mostraban sintomatología depresiva, tales como tristeza, desesperanza, cambios en el sueño y en el apetito, y episodios de llanto.
De todas maneras, no está muy claro que la depresión pueda aumentar el riesgo de partos prematuros. Con todo, varios estudios indican que la depresión afecta al sistema inmune con lo que podría incrementarse en esas mujeres el riesgo de infección, seguido de parto prematuro. Los investigadores consideran que los resultados, que publica "American Journal of Epidemiology", documentan una cierta asociación entre elevados niveles de síntomas depresivos en mujeres gestantes y parto prematuro espontáneo.
