That is the correct spelling of the adjective "perinatal" (around the time of birth).

The top ten leading causes of mortality in the Philippines in 2004 were:

* diseases of the heart

* diseases of the vascular system * malignant neoplasm * accidents * pneumonia * tuberculosis, all forms * ill-defined and unknown causes of mortality * chronic lower respiratory diseases * diabetes mellitus * certain conditions originating in the perinatal period.
