A STUDY OF INFANT MORTALITY FROM LINKED RECORDS

BY AGE OF MOTHER, TOTAL-BIRTH ORDER, AND OTHER VARIABLES

Helen M. Vavra and Linda J. Querec, Office of Health Statistics Analysis

INTRODUCTION

Linkage of infant death records with live-birth

records permits the calculation of infant mortality rates according to characteristics that are

reported only on the birth record. A total of

107,038 certificates for infant deaths occurring

in 1960 and 1961 were matched with certificates for live births occurring in 1960 to obtain

the data presented hsre on infant mortality

among a cohort of births in 1960. Certain

variables were selected from the matched records, and data were punched into a special deck

of cards for computer tabulation. The procedures utilized by the vital statistics reporting

areas that cooperated to provide the National

Center for Health Statistics with basic information for this study and also those for coding

and verifying the data are described in detail in

an earlier publication that also describes the

limitations of the data.1

The present report provides information that

relates infant mortality rates to age of mother,

total-birth order, and illegitimacy by sex, color,

and age at death of infant. Previous reports have

shown relationships of infant mortality to birth

weight and gestation period and have compared

neonatal data with similar linked data for the

1950 live-birth cohort.z ‘T

SOURCE OF DATA

Data for this nationwide study of infant

mortality were obtained from the files of individual live-birth and death records of 54 vital

statistics reporting areas, i.e., the 50 States and

the cities of Baltimore, New Orleans, New York

City, and Washington, D.C. The study was

undertaken by the National Center for Health

Statistics to probe aspects of infant mortality in

greater depth than is possible by the usual vital

statistics technique. When the usual method is

employed, rates are based on grouped data

obtained from independent sets of records of

births and of deaths that occurred during the

same period of time. These data include deaths

of infants born in the year prior to the record

year but not those of infants born in the record

year who died in the subsequent year before

reaching 1 year of age. In this linkage study, on

the other hand, certificates of live birth for

infants born in the study year were matched

with death certificates of infants who died

before reaching age 1.

A disadvantage of the usual method is that

analysis is limited to those items that appear in

both sets of records. Another is that information

obtained for identical items is not necessarily

the same on the death as on the birth certificate.

One possible source of inconsistency is place of

residence which may differ at time of death

from that at time of birth, so that death and

birth tabulations may show the same infant in

different geographic areas. The item on race is

another possible source of inconsistency. Birth

certificates require that the race of both parents

be recorded, and the race of the infant is

determined from that information. In contrast,

1
death certificates ask for the race of the decedent

which, in this study, is that of the infant.

Conditions for the inclusion of each individual in the study were that (1) the infant was

born alive in 1960 and died before reaching the

age of 1 year, and (2) both events occurred in

the United States. This method of linking birth

certificates with corresponding death certificates

has the advantage of dealing with individual

records rather than with grouped data. Additionally, more variables are available for study when

information is taken from both certificates.

Furthermore, discrepancies between information

on the two records are eliminated when data are

utilized from the birth record for those items

that appear on both certificates.

Infant mortality rates for the present study

are expressed as numbers of matched birth and

infant death records per 1,000 live births that

occurred in 1960. It should be noted that these

rates differ from those computed by conventional methods because of the differing bases.

Rates for 1960 that were calculated by the usual

method are slightly higher than those obtained

from the linked records in this study.1 ~s

Computations could have been based on number

of infants at risk—i.e., infants who survived to

each age at death—rather than on total live

births. For the characteristics included in this

report, however, there is virtually no difference

between rates computed in these two ways.

The limitations of the data, including those

resulting from record collection, are discussed in

detail in previous reports.1’3 It is worthy of

recall from these earlier reports that live-birth

records could not be located for some deaths

due in part to lack of birth registration. Unregistered births were not included in the cohort, and

it was not possible to determine the extent of

incompleteness of “registration. However, independent estimates by the Division of Vital

Statistics, National Center for Health Statistics,

indicated that in 1960 birth registration was

98.9 percent complete for the United States.1

The national data for this cohort, therefore,

were considered acceptably complete. Other

reasons for inability to locate records of live

birth include inconsistent spelling of infant’s

name on the birth and death records, change of

name due to adoption, and improper entry of

State of birth on the death record.

2

Of the 107,038 matched live-birth and death

records, 61,651 were for males, 45,387 for

females, 79,819 for white infants, and 27,219

for all other infants.

RESULTS

The chance of an infant surviving to the first

birthday historically has been less for males than

for females and less also for infants of other

races than for white infants.s -10 In this cohort,

the mortality rate for male infants exceeded that

for females by 30 percent. The rate for all other

infants was about double that for white infants.

These data also confirm the traditionally high

mortality of infants during the first days and

weeks of life. Forty percent of the infant deaths

occurred during the first day after birth and 65

percent during the first week.

Mortality rates for infants other than white

were higher than those for white infants at each

age at death. The relative differences were

greater during the postneonatal period (28 days11 months), 2.8 to 1, than during the neonatal

period, 1.6 to 1. Thus, the proportion of all

infant deaths that occurred in the neonatal

period was larger

other infants.

Age of Mother

Infants born to

for white infants than for all

mothers in their teens and to

mothers aged 40 years and over have less chance

of surviving to the first birthday than do infants

born to mothers at intermediate ages. The infant

mortality rate was highest for mothers aged

15-19; it declined sharply to the lowest rate at

ages 25-29 and increased gradually to nearly the

same high level at ages 40-44 (table A and figure

1).

Infant mortality rates for mothers in the

youngest and oldest age groups were 31 and 22

percent, respectively, above the rate for all

mothers, while the rate for mothers aged 25-29

was 11 percent lower. The high rate among

teenage mothers (ages 15-19) contributed

substantially to total infant. mortality. Births to

these young mothers accounted for 14 percent

of all births; the infant deaths among them

(19,240) constituted 18 percent of all infant

Although the overall mortality rate for all

other infants was about 87 percent above that

for white infants, the disadvantage associated

with the mothers of these infants being under

age 20 or 40 years and over was relatively small.

It should be noted that 20 percent of other

infants born alive were to teenage mothers as

contrasted with 13 percent of white live births.

A reasonable inference is that the proportionately smaller group of teenage mothers of white

infants were more highly selected with respect

to factors adversely affecting infant survival than

are the large group of teenage mothers of other

infants.

For both male and female infants, patterns of

mortality rates by maternal age were almost

identical (although the level of rates for males

was higher by about 30 percent). The main

exception was that, although there was an

increase in rates for both male and female

infants born to mothers aged 35 and over, the

increase for females was larger. This may,

perhaps, be explained partially as follows. First,

there is evidence that the frequency of plural

births increases with age of mother and that

fewer males from these pregnancies are liveborn,

i.e., the fetal death rate from such pregnancies is

probably greater for males than for females.11

Second, infants from these plural births are

generally of low weight at time of delivery and

have a high mortality risk. Thus, the greater

mortality rate of female infants of mothers 35

and over may reflect the higher mortality among

the “excess” of small Iiveborn females from

plural births.

Examination of the ratios of rates by maternal age for each color-sex group shows that the

smaller increase in rates for male than for female

infants of mothers 35 years and over occurred

only for the white group. However; the death

rate for male infants other than white was as low

at maternal ages 30-34 as at ages 25-29–the only

color-sex group for which this was true.

The U-shaped pattern of infant mortality

rates by maternal age (figure 1 and table A)

holds also for infants dying at various ages. This

is evident from the table below in which the rate

for each maternal age group is expressed as a

ratio of the rate for all ages in each age-at-death

category.

The chance of surviv~ for an infant born to a

teenage mother (aged 15-19), relative to the

chance for all infants, worsens substantially

during successive parts of the first year of life.

The same is true, to a minor degree, for infants

of mothers aged 20-24. On the other hand, the

relative chance of survival increases for infants

of mothers aged 30-39. The influence of

environmental factors as opposed to biological

factors on survival increases with time after

birth; these changes in relative chance of survival

perhaps reflect the more advantageous home

environment of infants of older mothers in

contrast to that of infants of very young

mothers. Neonatal mortality rates were lowest

for infants of mothers aged 25-29, while postneonatal mortality rates were lowest at ages

30-34. In addition, rates were lower for infants

of mothers aged 20-24 than for those aged 30-34

during the first week of life, while the reverse

was true for the remainder of the neonatal

period. This tendency was found to be more

marked for white than for all other infants.

Death rates for the latter were much higher than

those for the former at every age at death, but

especially after the first week of life. Thus, there

was less variation in risk by age at death among

all other infants than among white infants

regardless of maternal age.

Total-Birth Order

Total-birth order refers to the number of

children ever born to the mother; this includes

fetal deaths. In this report, the term “birth

order” is used interchangeably with “total-birth

order. ”

Infants of high birth order had the least

favorable chance of living to the first birthday;

those of first order, the best. Infant mortality

rates rose gradually through the fifth order, with

an abrupt rise at the higher orders (figure 2 and

table B). The latter rate exceeded that for first

births by 71 percent, and the rate for all births

by 45 percent. Sixth and higher order births

contributed considerably to total infant mortality; 11 percent of all births but 17 percent of all

deaths were of this category. Rates were highest

at the upper extreme for both white and all

other infants.

The pattern of rates for white infants by birth

order differed from that for all other infants.

Unlike rates for white infants, which increased

regularly throughout the birth-order span, those

for all other infants declined from second to

third, remained constant at fourth, then rose

(figure 2). These variations reflect the patterns

among infants other than white, both male and

female, who died during the first day after birth

and at ages 1-6 days (table B).

Figure 2. Infant mortality rates, by sex and color of infant and total-birth order: United States, 1960 Iiva-birth cohort.

Among white infant:, the rate for third births

was lower than that for second only for male

infants aged 1-6 days and for female infants

under 1 day of age.

The relationship of infant mortality to birth

order may be compared through examination of

the ratio of the rate for each birth order to the

rate for combined birth orders in each color-sex

group. The ratios showed that the variations

among males were similar to those among

females and also to those among white infants

regardless of sex. At the extremes of the

birth-order categories, the rates were, respectively, about 15 percent below and 45 percent

above the rates for allbirths within each of these

groups. Rates for fourth births were nearest

those for all births combined for each sex and

each color group.

For infants other than white, ratios for fifth extreme birth orders was narrower than for

and six”th births were much lower than those for white infants. The rate for first births was 12

white infants, but the ratios were based on percent lower and that for sixth and higher

relatively small numbers of deaths. Also, the births was only 11 percent greater than the

variation in rates for other infants between index rate (all birth orders).

Patterns of ratios by age at death for white

infants resembled the p~ttern for all white

infants combined. That is, most of the ratios for

the lower three birth orders were lower than the

index rate, and most of those for the higher

three orders exceeded the index rate. The

increase in rates with birth order is less for

deaths at 1-6 days than for deaths at under 1

day and at 1 week and over; the steepest

gradient is for postneonatal mortality, 28 days11 months of age.

As noted above, infant mortality varied less

by birth order for all other infants than for

white infants. There was no discernible change

in rates by birth order for deaths occurring at

ages under 1 day and 1-6 days. Postneonatal

mortality showed a definite increase with rise in

birth order, while death rates at ages 7-27 days

showed a somewhat irregular and weak pattern

of increase. Thus, birth order appeared to be an

important factor in neonatal mortality of white

infants but not of other infants. In the postneo-

.natal period birth order is a stronger factor

among white than among all other infants.

Infant mortality rates according to birth order

are shown in figure 3 by sex, color, and age at

death. In each color group, the patterns of rates

for males and females are similar. On the other

hand, age-at-death curves for white infants were,

with two exceptions, continuously upward,

while for all other infants they tended to

fluctuate.

In general, there was a narrowing of the color

differential with higher birth orders, and this

was true in each age-at-death group.

Age of Mother and Total-Birth Order

Infant mortality rates by birth order for ‘all

ages of mother ~ombined obscured differing

patterns at various age levels. Highly favorable

chances for surviving the first year of life

occurred among first infants of mothers in their

early twenties, first and second infants of

mothers in their later twenties, and third infants

of mothers in their early thirties (table C and

figure 4).

Rates by age of mother increased from first

birth order on for mothers under age 25, with

the increase being very sharp for teenage mothers (ages 15-19). For each 5-year age group from

25 on, rates declined through the lower birth

orders before rising at higher birth orders. There

is a clear pattern of high rates for high birth

order infants of young mothers, and for infants

of older mothers at extreme birth orders.

Attention was directed in a previous section

to rates for second births which, in some

segments of the cohort, were lower than those

for some later births. However, it is obvious

from table C that among mothers aged 30 and

over, rates for second births were higher than

those for third and/or fourth births. ‘These

variations were sufficiently strong among all

other infants of mothers ‘aged 30 and over to

markedly affect the overall birth order rates for

the group. A very slight but similar effect

prevailed for female infants.

have as much of an advantage over all other

groups under 30, the advantage declined with

Illegitimate Births

Some mortality data are available from the

1960 live-birth cohort regarding illegitimate

births. Because of problems in processing, data

for Legitimate births ordy are not avaiIabIe,

eliminating the possibility of comparisons between rates for legitimate and illegitimate births.

Of the 107,038 records in this cohort, 7,371

were for illegitimate births. Of the latter, 1,824

were for white infants and 5,547 were for all

other infants. The illegitimacy ratio was 0.5 per

1,000 for white infants and 8.0 per 1,000 for all

other infants. As in the instance of all live births,

mortality among illegitimate births was higher

for other infants than for white infants except at

ages under 1 week for infants of mothers aged

30 and over (table E and the following table).

For both color groups, mortality was higher

among illegitimate births than among all live

births (table E). The higher mortality among

illegitimate births may be attributable in part to

reluctance of the mothers to seek prenatal care.

Postnatal care too may have been inadequate

because of . lack - of financial resources and

perhaps because of lack of knowledge about

proper health care and nutrition. Forty percent

of the mothers were under 20 years of age and

70 percent were under 25. Furthermore, threefourths were mothers of all other infants;

perhaps many were in low-income brackets.

Factors in the socioeconomic environment,

therefore, may contribute to the levels of

mortality among illegitimate births.

Infant mortality rates by maternal age for

illegitimate births were similar for the two color

groups; that is, higher at the extremes than at

intermediate ages, as was the case for all live

births. For the latter, excess mortality risk in

each age-at-death category was largest in the

youngest age group. For illegitimate births, the

greatest risk was during the first 6 days among

white infants of mothers aged 30 years and over

and at ages 7 days and over among white infants

of mothers aged 25-29. Reasons for this cannot

be determined from the available data.

Among all live births, the ratio of the rate for

infants ~ther than white to that for white

infants was 1.6:1 during the neonatal period and

2.8:1 during the postneonatal period. Among

illegitimate births, the differentials were somewhat less, 1.2:1 and 2.6:1, respectively.

MORTALITY BASED ON SELECTED

FAVORABLE RATES

To what extent would the overall infant

mortality experience have been altered had more

advantageous rates been a reality for all infants?

This cohort of linked records shows the high

mortality among higher order births, especially

among sixth or later. births, in both sex and

color groups. One-sixth of all deaths were of

sixth or later birth order. These—together with

deaths of infants of mothers aged 15-19 years,

except first order—contributed sizably to the

overall infant mortality rate; 25 percent of all

deaths were from these groups. The impact on

the overall rate for infants other than white was

more severe, since 40 percent of all deaths

among them were from these two categories.

Only 20 percent of white infant deaths were

from the cited categories.

If all white infants had been born within

birth-order/age-of-mother categories showing the

most favorable rates for them, about 14,000

more would have survived the first year of life.

The mortality rate per 1,000 live births would

have been 18.2 rather than the actual rate of

22.2.

If, in turn, all other infants had been born

within similar categories showing the most favorable rates for them, 4,900 more would have

survived the first year, with a consequent rate of

35 per 1,000 live births–17 percent below the

actual rate of 41. In addition, losses would have

been reduced by 13,947, about one-half the

actual number, had these births occurred within

the above-mentioned most favorable categories

of white infants. The total of all deaths, both

white and all other, would then have been

28,000 fewer. The mortality rate would have

been 18 rather than 25 per 1,000 live births. It

should be recognized that these estimates are

based on rates which assume an ideal situation.

SUMMARY

Infant mortality data for this report were

obtained from 107,038 matched death and birth

certificates of infants born alive during 1960

who died before age 1. The matched records

made possible analysis of infamt mortality rates

according to maternal age, birth order, and other

characteristics reported on the certificates. Rates

were computed on a per 1,000 scale by dividing

the number of matched records by the number

of live births in 1960.

The rates varied with age of mother in much

the same way for each birth order. Each of these

variables wasassociated with infant mortality differentials, but there was also interaction between them in the association with infant

mortality. The chances of surviving the first year

of life were better for infants born to mothers

aged 20-34 years than for those born to mothers

of other ages, and better for infants of low birth

order than for infants of high birth order. The

most favorable survival rates were among first

births to mothers aged 20-24 and among first

and second births to mothers aged 25-29.

Infant mortality rates for illegitimate births

were half again as high as those for all infants in

the cohort. However, ratios of mortality rates

for illegitimate births to rates for all live births

were higher for white infants than for all other

infants.

Hypothetically, if all infants had been born

within categories of maternal age and birth order

having most favorable rates for white infants, an

estimated 28,000 fewer deaths would have

occurred. The infant mortality rate would have

been 18 per 1,000 live births rafher than 25. ~

APPENDIX 1

TECHNICAL NOTES

The data in this report are derived from two

sources. Data referring to all live births in 1960

are taken from Volume I of Vital Statistics of

the United States, 1960. Data on birth characteristics of infants in the 1960 live birth cohort

who died before reaching age 1 are derived from

computer tapes prepared from a new set of

punched cards which contained both birth and

death information.

The punching instructions for detailed

information in the new set of cards corresponded to the instructions for preparing cards

for use in Vital Statistics of the United States,

1960, The classification and interpretation of

certain important items is discussed in the

following pages. The complete rules followed in

the classification of geographic and personal

items for births are set forth in Vital Statistics

Instruction Manual. 13

Age of Mother

The birth certificate asks for “Age (at time of

this birth).” Some sources of minor errors in the

age data have been noted. A small number of

records are filed with age unspecified, and some

births are not registered. Measures of variation

of completeness of registration with age of

mother are availabIe from tests of completeness

in 1950 and 1940.14 ~15 They show that registration completeness is approximately the same

for all ages except for the oldest group, where it

is lower.

Color

The category “white” includes, in addition to

persons reported as white, persons reported to

be Mexican or Puerto Rican and those with race

not stated. The category “all other” consists of

persons reported as Negro, American Indian,

Chinese, and Japanese; persons of numerically

small racial groups; and persons of mixed white

and other races.

Completeness of birth registration in 1960 is

estimated by the Division of Vital Statistics,

National Center for Health Statistics, to be 99.3

percent for “white” births and 96.4 percent for

“all other” births. The most recent figures for

other groups are from the 1950 test which

indicated registration completeness at that time

to be 85.1 percent for American Indians and

97.4 percent for “other races,” chiefly Chinese

and Japanese. Both figures are probably higher

for 1960, but later data are not available.

A comparison of the race designation in

matched sets of birth certificates and infant

cards from the 1950 registration completeness

test indicates very high a~eement for white and

Negro infants. There were, however, substantially fewer American Indians recorded on birth

records than on census records.1 G

Control of Errors

The coding and punching of birth data for the

live birth records for 1960 were performed

simultaneously, and the major portion of the

work was verified using a partial sequential

sample. This procedure was used in verifying the

work of employees whose performance (as

indicated by complete verification) was such as

to produce consistently less than 4-percent error

distributed among all the items. For any one

item, less than l-percent error would be

expected under these procedures.

A new set of punched cards, using the same

procedures, was prepared for infant deaths

combining the necessary birth and death information into one card. However, to preserve the

consistency of the death information, once the

infant death was identified, the coded cause-ofdeath information from NCHS computer tapes

for all deaths was used.

49
Published data for all live births taken from

Volume I of Vital Statistics of the United States,

1960, were used. For live birth characteristics of

infant deaths, the newly created tapes were

used. There are no estimates available of the

degree of concordance between these two

sources of information. Tabulating, computing,

table preparation, and all other operations subsequent to the preparation of punched cards were

verified.

Sampling of Birth Records

In this report, birth data for 1960 have been

derived from a 5O-percent systematic sample

which consists of only even-numbered birth

records. Statistics for this year were obtained by

multiplying the sample figures by 2.

The sample data represent estimates which

differ somewhat from figures that would have

been derived by processing all the records.

However, the manner in which records are

numbered greatly reduces the sampling variability of totals for geographic areas. With few

exceptions, records are numbered in the State

offices of vital statistics as they are received

from the local offices. The assignment of the last

digit in the number is not selective, and the

systematic sample of even-numbered records

may be assumed to be unbiased.

The extent to which residence figures for

States derived from the sample differ from the

totals that would have resulted from a complete

count depends on the amount of nonresident

interchange. (This assumes virtually no error in

the figures on a place-of-occurrence basis.) Since

there is relatively little nonresident interchange

of births among the States, the sampling errors

for these geographic units are negligible.

The following table shows percent errors due

to sampling in the published birth data by other

than geographic characteristics. The chances are

about 2 out of 3 that the percent difference due

to sampling variability between the published

figure based on the 5O-percent sample and the

result that would be obtained by a complete

count is less than the appropriate percent error

shown in the table. The chances are about 19

out of 20 that the percent difference is less than

twice the percent error.

error will be shghtly larger.

Registration Completeness

Although every State has adopted a law

requiring the registration of births, deaths, and

fetal deaths, these laws are not uniformly

observed. In most areas practically all births and

deaths are registered. For some areas, however,

there is enough underregistration to affect the

use of the statistics for certain purposes.

Nationwide tests of completeness of birth

registration were made in both 1940 and

1950.1 4J1s For the United States as a whole,

these tests indicated that birth registration was,

respectively, 92.5 and 97.9 percent complete. A

detailed discussion of the results of these tests

was given in chapter 6, Volume I, Vital Statistics

of the United States, 1950. On the basis of

results of the 1950 test, it is estimated by the

Division of Vital Statistics that in 1960 birth

registration completeness was 98.9 percent for

I the country as a whole–99.3 for the white and

96.4 for all other groups, respectively.
