To quickly assess the difficulty of the text, read a short excerpt:
THE INFLUENCE OF PRENATAL CONDITIONS 31 remained practically stationary (46.9 in 1910-11 and 46.0 in 1911-12) ; while for each subsequent age period it decreased, the decline in the rate for the age period 1 to 3 months (20 per cent) being greater than that for any other age period (11 per cent for the period 3 to 6 months, 15 for the period 6 to 9, and 19 for the period from 9 to 12 months).* The marked decline in the rate for the period from 1 to 3 months is especially interesting, since it m...ay be partly due to the efficient "prenatal work" with expectant mothers that has been carried on in Boston throughout the four years. Perhaps if this work had not been done the decline in the rate for this age group would have been no larger than that which occurred in the registration area. Thus such figures as are available in this country reveal tendencies which are in exact accord with those shown by figures extending over a much longer period for England and Wales and for London. Now if this conclusion be accepted its significance is not difficult to discover, for, as has already been shown, the mortality of early infancy, and particularly the mortality of the first month, is largely determined by deaths from causes growing out of influences affecting the child's organism before birth — or, in other words, from the influence of prenatal conditions — while the mortality of the later months of infancy is largely deter- mined by the influence of conditions affecting the child's organism after birth — or, in other words, to the influence of postnatal conditions.
