Respiratory diseases were reported as a cause of death with almost as great frequency as diarrheal diseases. As shown by Table 19, these deaths occurred principally in the colder months of the first and fourth quarters of the calendar year.

Food is recognized as of such importance in relation to infant mortality that studies of this subject frequently resolve themselves into studies of feeding only. Invariably these demonstrate the truth of the statement of Dr. G. F. McCleary^[25] that “in human milk we have a unique and wonderful food for which the ingenuity of man may toil in vain to find a satisfactory substitute.” Many mothers, however, still fail to appreciate the risk their young babies face in being given any except the natural infant food, and consequently babies are in large numbers wholly or partly weaned from the breast in the earliest months of their lives.

Breast feeding is far more general, comparatively, among the poorer mothers than among the well to do, as shown by the following summary which gives the number and per cent. of babies of mothers with husbands earning varying incomes, who had been completely weaned from the breast when they were 3, 6, or 9 months of age, respectively. For each of the periods indicated the percentage completely weaned from the breast is much greater in the groups where earnings are highest.

Breast feeding, wholly or in part, is continued for a longer period by foreign than by native mothers, as indicated in the preceding table, showing that 20.3, 26.1, and 34.1 per cent. of the native mothers’ babies as compared with 6.4, 9.7, and 18.6 per cent. of the foreign mothers’ babies had been weaned from the breast at the age of 3, 6, and 9 months, respectively.

MOTHER’S HOUSEHOLD DUTIES, CESSATION AND RESUMPTION OF

The extent to which the native and foreign mothers in Johnstown relinquished a part of their household duties as the time for their confinement approached is shown below:

Among the 174 babies of mothers who relinquished part of their household duties a month before confinement, the infant mortality rate was 112.5, as compared with 136.7 for those of other mothers.

To what extent the relinquishment of household duties at a given time directly affected the health of the child can not be definitely shown. A relation may exist, but on the other hand the difference in the mortality rate may be due to the fact that the mothers could afford to give consideration to their condition and escape some of their heaviest tasks as their pregnancy approached its end, and were members of families who were thoughtful of them and relieved them of these tasks or employed extra household assistance at such times.

Another indication of intelligence and of comfortable surroundings is the care given a mother in the early days of her baby’s life, particularly if she is a nursing mother. The duration of her rest period before the resumption of part of her household duties is one measure of this. The foreign mothers, with less education, more numerous and arduous tasks, less opportunity for leisure, and smaller incomes, begin to resume their housework sooner than the native mothers with young babies.

The fact that a mother takes up her housework in the early days of her baby’s life does not necessarily increase the danger of its death. In some cases, however, mothers stated that the quantity of their breast milk was noticeably impaired when they got up and resumed their work too soon. Naturally this would affect the baby’s nutrition. In other cases a mother’s cares and duties may be so absorbing that she can not give the baby full attention. Whatever the exact explanation, attention should be called to the greater frequency of infant deaths when the mother resumed household duties very soon after childbirth.

A statement of the time of the mother’s resumption of household duties in full, like that giving the time of resumption in part, shows that the native mothers have the longer period of rest.

The infant mortality rates for all mothers in the group just referred to, according to the time of resuming housework in full after childbirth, show fewer infant deaths proportionately when the mother has had a longer rest; that is, a rest of two weeks or more.

ECONOMIC FACTORS

EARNINGS OF FATHER

A grouping of babies according to the income of the father shows the greatest incidence of infant deaths where wages are lowest, and the smallest incidence where they are highest, indicating clearly the relation between low wages and ill health and infant deaths.

For all live babies born in wedlock the infant mortality rate is 130.7. It rises to 255.7 when the father earns less than $521 a year or less than $10 a week, and falls to 84 when he earns $1,200 or more or if his earnings are “ample.”^[30] The variation in the infant mortality rate from one earnings group to another is not perfectly regular and consistent, but if any two or more consecutive groups are combined an invariable lowering of the infant mortality rate from one such combined group to that next higher results.

In considering the babies of native and of foreign mothers separately in the foregoing table, similar variations in mortality rates according to earnings of father are found, although the foreign infant death rate is higher in each group. The foreign are less numerous both actually and relatively in the higher wage groups.

The foreigners of a given wage group almost always live in a poorer neighborhood than the natives earning the same amount. The foreigners go where they find their own countrymen, most of whom are poor, and hence even those who earn a fair wage find themselves, until they become Americanized, surrounded by poor conditions and an ignorant class of people.

It is of interest to note what per cent. of the native and what per cent. of the foreign are in the several earnings groups. The next table shows this for all married mothers and not simply for those of live-born babies as in the foregoing table.

The 1,491 married mothers included in the foregoing table bore 1,517 babies in 1911, the excess being due to plural births. The 33 unmarried mothers and their 34 babies (one mother had twins), although included in some of the general tables, are not included in those relative to the earnings of the husband.

GAINFUL WORK OF MOTHER

In localities where large numbers of women are engaged in industrial work, comparisons are frequently made of the death rates among their babies with those of the babies of mothers not so engaged. In Johnstown, however, industrial occupations are not open to women, and but 3.1 per cent. of the mothers visited went outside their homes to earn money. All mothers who gained money by keeping lodgers or in any other way are, for convenience, designated “wage-earning” mothers, even though their earnings were not in the form of a definite wage at stated periods.

Although not industrially engaged, nearly one-fifth of the mothers did resort to some means of supplementing the earnings of their husbands. Usually they kept lodgers. This was done by the foreign mothers principally, exactly one-third of whom had lodgers, as compared with less than 1 per cent. of the native women. Usually work done outside the home consisted either of char work or of assisting husbands in their stores. Generally these stores were in the same building with the home.

When a mother of a young baby does not give her full time to her duties within the home but resorts to means of earning money, it generally indicates poverty. This is true to a greater degree in Johnstown than in places which have many inducements for women to work. In Johnstown, with its excess of males, especially in the foreign population, the woman’s services are particularly needed to make the home.

In the group where the husband earns $10 a week or less—that is, under $521 a year—many of the women are wage earners. In each group showing better earnings for the husband the number and percentage of wage-earning wives decline. Such a tabulation as the following almost automatically fixes the minimum wage on which a man, wife, and a child or two can live with any degree of comfort in Johnstown at about $780 a year. When the husband’s wage is less than $780 a year, it is shown that the wives, in considerable number, must be wage earners. As shown in the next table, in nearly half of the families where the husband earns $10 a week or less (less than $521 a year), the wife resorted to some means of earning money; when he earned as much as $900 a year, only 8.9 per cent. of the wives worked, and in the small group where the man earns as much as $1,200 a year, only 1 in 50.
