We’ve become accustomed to hearing from the Chief and Deputy Officers of Health for England on a regular basis over the last few weeks. But did you know that each local authority also has a Medical Officer of Health (MoH) and that the first one for Birmingham was appointed back in 1872? The Annual Reports of the MoH make fascinating reading. Printed copies of the Birmingham MoH reports (& those of the School’s MoH) can be viewed on request at the Library of Birmingham when it is open, but they can also be found online at the Wellcome Collection http://search.wellcomelibrary.org/ – Simply search for “medical officer of health birmingham” and the year of interest between 1873 and 1973 and lose yourself for a few hours.
David Low, one of our volunteer researchers and an retired paediatrician made extensive use of the MoH reports in his research on the Infant Mortality Rate during our period of study. This is a summary of some of his findings:
Why so much emphasis on Infant Mortality Rate [IMR], deaths under 1 year of age per 1000 live births?

Dr John Robertson Medical officer for Health submitted his report of “Child Welfare in 1913” to the Public Health and Housing Committee in May 1914.
“the extent of Infant mortality in Birmingham…and the amount of permanent damage to young children done by the ignorance and carelessness on the part of parents is still so great …to consider whether something further cannot be done to prevent this unnecessary waste of human life”. In 1913 4257 [33%] of all deaths were in children under 3 and 3070 [23.7%] under 1. He considered that half were preventable, noted that areas of “careful artisans” had an IMR half that of areas of poverty and the resulting inefficiency & carelessness. His ward maps demonstrated the relationship of infant mortality to the gradient of socio-economic deprivation [my words not his], between the Central, Middle and Outer Wards.
He considers that much of the inefficiency of adults has its origin in their own preventable childhood illnesses. This equates with the concerns of the Infant Welfare Movement and its emphasis on physical development and the quality rather than the quantity of the population in an era of declining birth-rate.
He states that the real object of the report is “to suggest further methods of imparting information to adults as to the rearing of young children and to suggest methods of dealing with the health of parents so that a healthy stock may be produced”.
Was he successful?
The yearly MOH reports contain a plethora of statistics. As a retired Consultant Paediatrician, I have recalculated and reinterpreted them to try and answer the question
In 1913 86% of deaths under 1 could be classified as due to either Perinatal causes [38%] or Infection [48%].
Perinatal causes were classified as “largely due to some defect on the part of the mother” and were mainly responsible for deaths in the first week or first month of life; premature birth, congenital malformations and a complex heading of debility, atrophy and marasmus. Marasmus is derived from the Greek, meaning to waste away and is generally applied to the undernourishment of the child.
Despite the expansion of the Maternity and Infant Welfare Centres and their staff, and the increasing emphasis on improving antenatal care, there was no improvement in the IMRs for premature birth and congenital malformations by 1924. However, I think we can attribute the 50% fall in IMR for debility, atrophy and marasmus to the education on feeding in those centres and the referral from them to defined beds in Barnt Green in 1916 and later to Witton Babies Hospital in 1921, where 102 marasmic babies were admitted with “good results”.

These charts show the growth rate of selected babies at Carnegie Institute when specific support measures were put in place to support feeding.
Infant Mortality Rates are composed of the following: Neonatal mortality rate (deaths in the first 4 weeks of life per 1000 live births) which only fell by 13.2% [41 to 34.6], whereas the Post Neonatal Mortality rate (deaths between 4 week and 1 year per 1000 live births) fell by 45.32% [87.9 to 48.06]. This strongly suggests that the majority of the reduction occurred in infectious diseases. The death rate in the 0-5 year child population also fell by 34.8% over this period.
Infectious diseases

Diarrhoea and enteritis
This was the great success story, with deaths under 1 year reduced from 746 [25%] in 1913 to 160[11%] in 1924, and the IMR falling from 31.3 to 8.7. Dr Robertson described this as the “most easily preventable” and that “dirt in various forms is the exciting cause of the disease”. Hot weather, precipitating summer epidemics, was dreaded. Education by Health Visitors and the Maternity and Infant Welfare Centres about hygiene and feeding, especially breast feeding, was the key to this improvement. Handbills such as “Protecting Babies during Hot Weather” in 1914
and “Prevention of Flies” in 1915 were distributed to all houses in the poorest areas.
Public health issued byelaws requiring owners to provide portable galvanised dustbins, and a booklet for stable owners to remove horse dung and weekly emptying of ashbins and ashpits. Robertson also highlighted the lack of storage facilities for food and the dust from street horse dung blowing directly into many living rooms.
Nearby manure was still a problem in 1921 when Witton Babies Hospital had to cover babies with mosquito nets and empty fly traps containing 100-500 flies every 2 hours.
Measles, Whooping Cough, Scarlet Fever and Diphtheria
The burden of these diseases for all children, especially the under 5s, was immense. Between 1914-24 there were 14,383 cases of diphtheria and 89,143 cases of measles reported [underestimate], and 12961 cases of whooping cough between 1916-18. There was no change in incidence. Being highly infectious they were no respecter of class or ward and carried important sequelae for adult life. Mortality remained high, particularly for young children, and 4 or 5 times higher in the inner poorer wards. Between 1916-24 deaths under 5 years from measles were 1441 and from whooping cough 1912. From 1914 Nursing Societies were contracted to supply a visiting nurse for severe cases of measles, and then whooping cough, as expert nursing was felt to be key. Whereas all diphtheria cases were admitted to hospital, there was debate about whether severe cases of measles and whooping cough especially from dirty and poor houses should be admitted to hospital, Capacity and expense were issues and in the case of whooping cough the “high mortality” “would alarm the community” and bring “any hospital into disrepute”.
Scarlet Fever was primarily a mild disease of older children but with important sequelae. There were 23,766 cases between 1916 and 1924, with a case mortality for under 5s reduced from 6% in 1913 to 2.7 % in 1924.
Diphtheria
Dr Robertson’s 1924 report describes advances in the management of this disease. The use of high doses of antitoxin to treat cases early was introduced in Birmingham in the 1890s and this, combined with hospital admission for all cases and skilled nursing, had resulted in case mortality dropping from 29.2% [1890-93] to 14.5% [1913-16] to 8.5% [1920-23], although case mortality for the under 5s was still 17% in 1923. Immunisation of nursing staff working on diphtheria wards introduced in 1921, using a mixture of toxin and antitoxin, meant that meant no nurse had contacted the disease compared to 13 in 1918
In 1924, it was approved that all children between 2 and 5 should be immunised by 3 weekly injections.
Pneumonia and Bronchitis
The IMR remained consistently high fluctuating between 15 and 21 for this collection of respiratory illnesses. In 1924, it was the cause of 661 under 5 deaths, of which 55% were under 1.
Summary

Between 1913 and 1924 there was a very significant reduction in “the waste of human life” to quote Dr Robertson. A 35.6% fall in the infant mortality rate from 129 to 83, a similar decline in children under 5, and these declines were not interrupted by World War 1 or the post war depression. These were reflected in the three ward area categories and compared favourably with the rates of England and Wales and other large towns. In 1924 2128 [19%] of all deaths were in children under 3, 1518 [13.56 %] under 1, and there had been significant reductions in deaths from marasmus and diarrhoeal disease. However, the burden of other childhood infectious diseases remained high.
