x-rayed were aged and infirm. The initial examination consisted
of a 35-mm photofluorographic roentgenogram that, if the x-ray
‘shadows were suspiciously abnormal, was followed by a 14- by 17inch chest roentgenogram. The findings reported in this survey
were made from the 14- by 17-inch films without further clinical
study.
On the basis of these examinations 4.5 percent of those x-rayed
were found to have chest defects. and 1.3 percent were suspected of
having active pulmonary tuberculosis. The number of chest tumors,
cardiovascular abnormalities, and bone deformities was negligible,
none being over0.3 percent of the total x-rayed.
The prevalence rates for active pulmonary tuberculosis increase
with age, showing but little variation by sex. The proportion of
active-pulinonary-tuberculosis suspects among those x-rayed is greatest for those 45 years of age andover, 3.2 percent as compared with
, the next highest rate of 1.2 percent for the 25- to t4-year age group.
Only slight ditterences were noted between rates for both sexes, the
overall rate for females exceeding that for males by 0.1 percent.
Of the three districts Saipan has the highest percentage of chest
defects, with Palau ranking second and the Marshall Isiands lowest
of all, 5.4, 4.4, and3.9 percent. respectively. Of the persons x-raved
-
only 0.7 percent in the Marshall Islands, 1.5 percent in Palau, and
1.6 percent in Saipan were recorded as being suspected of having
active pulmonary tuberculosis.
On the basis of the chest roentgenowrams performed (table 14}, 10
islands had no active pulmonary tuberculosis. On the other islands
the percentige of positive Alms for the x-rayed population ranged
from Kwajalein’s 0.1 to Faraulep’s 6.8. On six of these islands or
