CHAPTER XIII

VITALITY TESTS AND VITAL STATISTICS

Two things will disclose the strength or weakness of a bank and the

soundness or unsoundness of a nation's banking policy, namely, a

financial crisis or an expert audit. A searching audit that analyzes

each debit and each credit frequently shows that a bank is solvent only

because it is not asked to pay its debts. It continues to do business

so long as no obvious weaknesses appear, analogous to measles,

adenoids, or paralysis. A frequent disorder of banking results from

doing too big a business on too little capital, in making too many

loans for the amount of cash held ready to pay depositors upon demand.

This disorder always comes to light in a crisis--too late. It can be

discovered if looked for in advance of a crisis. Many individuals and

communities are likewise physically solvent only because their physical

resources are not put to the test. Weaknesses that lie near the surface

can be discovered before a crisis by physical examination for

individuals and sanitary supervision for communities. Whether

individuals or communities are trying to do too much business for their

health capital, whether the health reserves will pay debts that arise

in a crisis, whether we are ill or well prepared to stand a run on our

vitality, can be learned only by carefully analyzing our health

reserves. Health debits are compared with health credits for

individuals by vitality tests, for communities by vital statistics.

Of the many vitality tests none is practicable for use in the ordinary

class room. Scientific training is just as necessary for such tests as

for discovering the quality of the blood, the presence or absence of

tubercle bacilli in the sputum, diphtheria germs in throat mucus, or

typhoid germs in milk. But scientific truth, the results of scientific

tests, can be made of everyday use in all class rooms. State and

national headquarters for educators, and all large cities, can afford

to engage scientists to apply vitality tests to school children for the

sake of discovering, in advance of physical breakdown and before

outward symptoms are obvious, what curriculum, what exercise, what

study, recreation, and play periods are best suited to child

development. It will cost infinitely less to proceed this way than to

neglect children or to fit school methods to the loudest, most

persistent theory.

The ergograph is an interesting strength tester. It takes a picture (1)

of the energy exerted, and (2) of the regularity or fitfulness of the

manner in which energy is exerted. Perhaps the time will come when

science and commerce will supply every tintype photographer with an

ergograph and the knowledge to use it. Then we shall hear at summer

resorts and fairs, "Your ergograph on a postal card, three for a

quarter." We can step inside, harness our middle finger to the

ergograph, lift it up and down forty-five times in ninety seconds, and

lo! a photograph of our vitality! If we have strong muscles or good

control, the picture will be like this:

[Illustration: FIG. 1. Ergogram of T.R., a strong, healthy girl,

before taking 40 minutes' work in the gymnasium. Weight used,

3.5 kg. Distance lifted, 151 cm. Work done, 528.5 kg.-cm.]

If weak and nervous, we shall look like this before taking exercise:

[Illustration: FIG. 2. Ergogram of C.E., a weak and somewhat

nervous girl, before taking 40 minutes' work in the gymnasium.

Weight used, 3.5 kg. Distance lifted, 89 cm. Work done, 311.5

kg.-cm.]

And like this after gymnasium exercise:

[Illustration: FIG. 3. Ergogram of C.E. after taking 40 minutes'

work in the gymnasium, showing that the exercise proved very

exhausting. Weight used, 3.5 kg. Distance lifted, 55 cm.]

In Chicago, two of whose girls are above photographed, the physician

was surprised to have four pupils show more strength late in the day

than in the morning. "Upon investigation it was found that the teacher

of the four pupils had been called from school, and that they had no

regular work, but had been sent to another room and employed

themselves, as they said, in having a good time." The chart on page 127

shows the effect of the noon recess and of the good time after three

o'clock.

Chicago's child-study experts concluded after examining a large number

of children:

1. In general there is a distinct relationship in children between

physical condition and intellectual capacity, the latter varying

directly as the former.

2. The endurance (ergographic work) of boys is greater than that

of girls at all ages, and the difference seems to increase after

the age of nine.

3. There are certain anthropometric (body measurements)

indications which warrant a careful and thorough investigation

into the subject of coeducation in the upper grammar grades.

4. Physical condition should be made a factor in the grading of

children for school work, and especially for entrance into the

first grade.

5. The great extremes in the physical condition of pupils in the

upper grammar grades make it desirable to introduce great

elasticity into the work of these grades.

6. The classes in physical culture should be graded on a physical

instead of an intellectual basis.

[Illustration: FIG. 4]

To these conclusions certain others should be added, not as settled

beyond any possibility of modification, but as being fairly indicated

by these tests.

1. The pubescent period is characterized by great and rapid

changes in height, weight, strength of grip, vital capacity, and

endurance. There seems to accompany this physical activity a

corresponding intellectual and emotional activity. It therefore is

a period when broad educational influences are most needed. From

the pedagogic standpoint it is preëminently a time for character

building.

2. The pubescent period is characterized by extensive range of all

physical features of the individuals in it. Hence, although a

period fit for great activity of the mass of children, it is also

one of numerous individual exceptions to this general law. During

this period a greater per cent of individuals than usual pass

beyond the range of normal limits set by the mass. It is a time,

therefore, when the weak fail and the able forge to the front, and

hence calls for a higher degree than usual of individualization of

educational work and influence.

3. Unidexterity is a normal condition. Rapid and marked

accentuation of unidexterity is a pubescent change. On the whole,

there is a direct relationship between the degree of unidexterity

and the intellectual progress of the pupil. At any given age of

school life bright or advanced pupils tend toward accentuated

unidexterity, and dull or backward pupils tend toward

ambidexterity.... Training in ambidexterity is training contrary

to a law of child life.

4. Boys of school age at the Bridewell (reform school) are

inferior in all physical measurements to boys in the ordinary

schools, and this inferiority seems to increase with age.

5. Defects of sight and hearing are more numerous among the dull

and backward pupils. These defects should be taken into

consideration in the seating of pupils. Only by removing the

defects can the best advancement be secured.

6. The number of eye and ear defects increases during the first

years of school life. The causes of this increase should be

investigated, and, as far as possible, removed.

7. There are certain parts of the school day when pupils, on the

average, have a higher storage of energy than at other periods.

These periods should be utilized for the highest forms of

educational work.

8. The stature of boys is greater than that of girls up to the age

of eleven, when the girls surpass the boys and remain greater in

stature up to the age of fourteen. After fourteen, girls increase

in stature very slowly and very slightly, while boys continue to

increase rapidly until eighteen.

9. The weight of the girl surpasses that of the boy about a year

later than her stature surpasses his, and she maintains her

superiority in weight to a later period of time than she maintains

her superiority in height.

10. In height, sitting, girls surpass boys at the same age as in

stature, namely, eleven years, but they maintain their superiority

in this measurement for one year longer than they do in stature,

which indicates that the more rapid growth of the boy at this age

is in the lower extremities rather than in the trunk.

11. Commencing at the age of thirteen, strength of grip in boys

shows a marked accentuation in its rate of increase, and this

increase continues as far as our observations extend, namely, to

the age of twenty. In girls no such great acceleration in muscular

strength at puberty occurs, and after sixteen there is little

increase in strength of grip. The well-known muscular

differentiation of the sexes practically begins at thirteen.

12. As with strength of grip, so with endurance as measured by the

ergograph; boys surpass girls at all ages, and this

differentiation becomes very marked after the age of fourteen,

after which age girls increase in strength and endurance but very

slightly, while after fourteen boys acquire almost exactly half of

the total power in these two features which they acquire in the

first twenty years of life.

13. The development of vital capacity bears a striking resemblance

to that of endurance, the curves representing the two being almost

identical.

Physiological age, according to studies made in New York City, should

be considered in grading, not only for physical culture classes but for

all high school or continuation classes. Dr. C. Ward Crampton,

assistant physical director, while examining boys in the first grade of

the High School of Commerce, noticed a greater variation in physical

advancement than in years. He kept careful watch of the educational

progress and discovered three clear divisions: (1) boys arrived at

puberty,--postpubescent; (2) boys approaching maturity,--pubescent; (3)

boys not yet approaching maturity,--prepubescent.

The work in lower grades they had all passed satisfactorily, but in

high school only the most advanced class did well. Practically none of

the not-yet-maturing boys survived and few of the almost mature. In

other words, the high school course was fitted to only one of the three

classes of boys turned out of the grammar schools. The others succumbed

like hothouse azaleas at Christmas time, forced beyond their season.

Physiological age, not calendar years or grammar school months, should

determine the studies and the companions of children after the tenth

year. Physiological strength and vitality, not ability to spell or to

remember dates, should be the basis of grading for play and study and

companionship among younger children. Vitality, power to endure

physically, should be the test of work and recreation for adults.

Physicians may be so trained to follow directions issued by experts

that physical examinations will disclose the chief enemies of vitality

and the approximate limits of endurance.

Teachers may train themselves to recognize signs of fatigue in school

children and to adapt each day's, each hour's work to the endurance of

each pupil. One woman principal has written:

School programmes, after they have been based upon the laws of a

child's development, should provide for frequent change of

subject, alternating studies requiring mental concentration with

studies permitting motor activity, and arranging for very short

periods of the former. Anæmic children should be relieved of all

anxiety as to the results of their efforts, and only short hours

of daylight work required of them. The disastrous consequences of

eye strain should be understood by all in charge of children who

are naturally hypermetropic. The ventilation of a class room is

far more important than its decoration or even than a high average

percentage in mathematics, and the lack of pure air is one of the

auxiliary causes of nervous exhaustion in both pupils and

teachers. Deficient motor control is a most trustworthy indication

of fatigue in children, and teachers may safely use it as a rough

index of the amount of effort to be reasonably expected of their

pupils. Facial pallor or feverish flushes are both evidences of

overtasking, and either hints that fatigue has already begun. As

to unfavorable atmospheric conditions, the teacher herself will

undoubtedly realize them as soon as the children, but she should

remember that effort carried to the point of exhaustion, injurious

as it is in an adult, is yet less harmful than it is to the

developing nerve centers of the child.

Because adults at work and at play reluctantly submit themselves to

vitality tests, because few scientists are beseeching individuals to be

tested, because almost no one yearns to be tested, the promotion of

adult vitality and of community vitality can best be hastened by

demanding complete vital statistics. Industrial insurance companies and

mutual benefit societies are doing much to educate laborers regarding

the effect upon vitality of certain dangerous and unsanitary trades,

and of certain unhygienic habits, such as alcoholism and nicotinism.

Progress is slower than it need be because state boards of health are

not gathering sufficiently complete information about causes of

sickness and death. American health and factory inspection is not even

profiting, as it should, from British, German, and French statistics.

Statistics are in ill repute because the truth is not generally known

that our boasted sanitary improvements are due chiefly to the efficient

use of vital statistics by statesmen sanitarians.[7]

The vital statistics of greatest consequence are not the number of

deaths or the number of births, not even the number of deaths from

preventable diseases, but rather the number of cases of sickness from

transmissible diseases. The cost and danger to society from preventable

diseases, such as typhoid, diphtheria, scarlet fever, measles, are

imperfectly represented by the number of deaths. Medical skill could

gradually reduce death rates in the face of increasing prevalence of

infectious disease. With few exceptions, only those patients who refuse

to follow instructions will die of measles, diphtheria, or smallpox.

The scarlet-fever patient who recovers and goes to church or school

while "peeling" can cause vastly more sickness from scarlet fever than

a patient who dies. Dr. W. Leslie Mackenzie, who has recently written

_The Health of the School Child_, said ten years ago, while health

officer of Leith:

Death is the ultimate and most severe injury that any disease can

inflict, but short of death there may be disablement, permanent or

temporary, loss of wages, loss of employment, loss of education,

increase of home labor, increase of sickness outlays, increase of

worry, anxiety and annoyance, disorganization of the household,

general impairment of social efficiency.

The best guarantee against such loss, the best protection of health,

and the most essential element of vital statistics is prompt, complete

record of cases of sickness. Statistics of sickness are confined to

sickness from transmissible diseases, because we have not yet arrived

at the point where we recognize the state's right to require

information, except when the sick person is a menace to the health of

other persons.

The annual report of a board of health should give as clear a picture

of a community's health during the past week or past quarter as the

ergograph gives of the pupils mentioned on page 126. As ragged, rapidly

shortening lines show nervousness and depleted vitality, so charts and

diagrams can be made to show the needless waste of infant life during

the summer months, the price paid for bad ventilation in winter time,

when closed windows cause the sickness-and-death line from diphtheria

and scarlet fever to shoot up from the summer level. In cities it is

now customary for health boards to report weekly the number of deaths

from transmissible diseases. Health officers will gladly furnish facts

as to cases of sickness, if citizens request them. Newspapers will

gladly publish such information if any one will take the pains to

supply it. Wherever newspapers have published this information, it

quickly takes its place with the weather reports among the news

necessities. Marked changes are commented on editorially. Children can

easily be interested, as can adults, in filling out week by week a

table that will show increases and decreases in preventable sickness

due to transmissible diseases.

In cities where physicians are not compelled to notify the health board

of danger centers,--that is, of patients sick from measles, smallpox,

or diphtheria,--and in smaller communities where notices are sent only

to state boards of health, parents will find it difficult to take a

keen interest in vital statistics. But if teachers would start at the

beginning of the year to record in such a table the days of absence

from school because of transmissible disease, both they and their

pupils would discover a new interest in efficient health

administration. After a national board of health is organized we may

reasonably expect that either state boards of education or state boards

of health will regularly supply teachers with reports that will lead

them to compare the vitality photographs of their own schools and

communities with the vitality photographs of other schools and other

communities working under similar conditions. Then children old enough

to study physiology and hygiene will be made to see the

happiness-giving possibilities of vitality tests and vital statistics.

[Illustration: VITAL STATISTICS CAN MAKE DISEASE CENTERS AS

OBVIOUS AND AS OFFENSIVE AS THE SMOKE NUISANCE]

Instead of discussing the theory of vital statistics, or the extent to

which statistics are now satisfactory, it would be better for us at

this point to make clear the significance of the movement for a

national fact center for matters pertaining to personal, industrial,

and community vitality. Five economic reasons are assigned for

establishing a national department of health:

1. To enable society to increase the percentage of exceptional men

of each degree, many of whom are now lost through preventable

accidents, and also to increase the total population.

2. To lessen the burden of unproductive years by increasing the

average age at death.

3. To decrease the burden of death on the productive years by

increasing the age at death.

4. To lessen the cost of sickness. It is estimated that if illness

in the United States could be reduced one third, nearly

$500,000,000 would be saved annually.

5. To decrease the amounts spent on criminality that can be traced

to overcrowded, unwholesome, and unhygienic environment.

In addition to the economic gain, the establishment of a national

department of health would gradually but surely diminish much of

the misery and suffering that cannot be measured by statistics.

Sickness is a radiating center of anxiety; and often death in the

prime of life closes the gates of happiness on more than one life.

Let us not forget that the "bitter cry of the children" still goes

up to heaven, and that civilization must hear, until at last it

heeds, the imprecations of forever wasted years of millions of

lives.

If progress is to be real and lasting, it must provide whatever

bulwarks it can against death, sickness, misery, and ignorance;

and in an organization such as a national department of health,

adequately equipped,--a vast preventive machine working

ceaselessly,--an attempt at least would be made to stanch those

prodigal wastes of an old yet wastrel world.

Among the branches of the work proposed for the national bureau are the

following: infant hygiene; health education in schools; sanitation;

pure food; registration of physicians and surgeons; registration of

drugs, druggists, and drug manufacturers; registration of institutions

of public and private relief, correction, detention and residence;

organic diseases; quarantine; immigration; labor conditions;

disseminating health information; research libraries and equipment;

statistical clearing house for information.

Given such a national center for health facts or vital statistics,

there will be a continuing pressure upon state, county, and city health

officers, upon physicians, hospitals, schools, and industries to report

promptly facts of birth, sickness, and death to national and state

centers able and eager to interpret the meaning of these facts in such

simple language, and with such convincing illustrations, that the

reading public will demand the prompt correction of preventable evils.

Our tardiness in establishing a national board of health that shall do

this great educational work is due in part to the fact that American

sanitarians have frequently chosen to _do things_ when they should have

chosen to _get things done_. Almost every state has its board of

health, with authority to require registration of births, deaths, and

sickness due to transmissible disease; with few exceptions the heads of

these state boards have spent their energies in abating nuisances. In a

short time they have degenerated into local scavengers, because they

have shown the public neither the meaning of the vital statistics

gathered nor its duty to support efficient health administration.

The state reports of vital statistics have not been accurate; therefore

in many states we have the anomalous situation of an aggressive

veterinary board arousing the farmer and the consumer of milk to the

necessity of protecting the health of cattle, and an inactive,

uninformed state board of health failing to protect the health of the

farmer and the consumer.

Vital statistics presume efficient health administration. An

inefficient health officer will not take the initiative in gathering

health statistics. If some one else compels him to collect vital

statistics, or furnishes him with statistics, they are as a lantern to

a blind man. Unless some one also compels him to make use of them,

unless we remove the causes of transmissible or infectious diseases and

check an epidemic when we first hear of it, the collection of

information is of little social value. "Statistics" is of the same

derivation as "states" and "statesmen." Statistics have always been

distinguished from mere facts, in that statistics are instruments in

the hands of the statesman. Wherever the term "statistics" is applied

to social facts it suggests action, social control of future

contingencies, mastery of the facts whose action they chronicle. The

object of gathering social facts for analysis is not to furnish

material for future historians. They are to be used in shaping future

history. They are facts collected with a view to improving social

vitality, to raising the standard of life, and to eliminating

permanently those forces known to be destructive to health. Unless they

are to be used this way, they are of interest only to the historical

grub. No city or state can afford to erect a statistical office to

serve as a curiosity shop. Unless something is to be done to prevent

the recurrence of preventable diseases annually experienced by your

community or your school, it is not reasonable to ask the public

printer to make tables which indicate the great cost of this

preventable sickness. A tax collector cannot discharge his duties

unless he knows the address of every debtor. The police bureau cannot

protect society unless it knows the character and haunts of offenders.

A health officer cannot execute the law for the protection of society's

health unless he knows the haunts and habits of diseases. For this he

must look to vital statistics.

But the greatest service of vital statistics is the educational

influence. Health administration cannot rise far above the hygienic

standards of those who provide the means for administering sanitary

law. The taxpaying public must believe in the economy, utility, and

necessity of efficient health administration. Power and funds come

from town councils and state legislatures. To convince and move these

keepers of the purse, trustworthy vital statistics are indispensable.

Information will be used for the benefit of all as soon as it is

possessed by all.

Fortunately the gathering of vital statistics is not beyond the power

of the kind of health officer that is found in small cities and in

rural communities. If years of study of mathematics and of the

statistical method were required, we should despair of obtaining light

within a century. But the facts we want are, for the most part, common,

everyday facts, easily recognizable even by laymen; for example,

births, deaths, age at death, causes of death, cases of transmissible

diseases, conditions found upon examination of children applying for

work certificates, etc. Where expert skill is required, as at state and

national headquarters, it can be found. Every layman can train himself

to use skillfully the seven ingredients of the statistical method which

it is his duty to employ, and to know when to pay for expert analysis

and advice. We can all learn to base judgment of health needs upon the

seven pillars,--desire to know, unit of inquiry, count, comparison,

percentages, classification, and summary.
