Three ways to improve child health

Jan 10,2017 - Last updated at Jan 10,2017

Over the last 15 years, the international community has made great strides in improving child health. But with millions of children under the age of five dying each year from preventable and treatable diseases like diarrhoea and pneumonia, the job is far from finished.

Most people would say that malaria or even HIV/AIDS are the leading child killers. 

In fact, diarrhoea and pneumonia top the charts as the biggest threats to child survival — as they have for the more than 30 years that we have been tracking them.

According to the recently published 2016 Pneumonia and Diarrhoea Progress Report, the two diseases caused 1.4 million child deaths last year, and one-quarter of all deaths of children under the age of five. 

They exact their highest toll in South Asia and sub-Saharan Africa.

Tackling the two biggest killers of children worldwide may seem daunting, but we have all the knowledge we need to mount an effective response.

Indeed, we know which viruses, bacteria and parasites we need to target; which interventions are likely to work; and which countries need them the most.

Just 15 countries account for 72 per cent of childhood deaths from pneumonia and diarrhoea.

These are the countries on which the Pneumonia and Diarrhoea Progress Report focuses. Its analysis of national efforts shows that, while most countries have made improvements over the last year, improvement in some of the largest countries has been minimal and a few countries have not made any progress at all. 

Most deaths happen in the first two years of a child’s life.

To change this, governments need to step up their efforts to prevent pneumonia and diarrhoea, including by ensuring that parents have access to the information they need to protect their children.

Here, it is critical that ordinary citizens stand up and hold their governments accountable.

The good news is that there are three relatively simple interventions that could make a big difference.

The first is breastfeeding. An age-old, no-cost intervention, breastfeeding exclusively for the first six months of a baby’s life is one of the easiest ways to prevent both diarrhoea and pneumonia.

Breast milk has all the nutrients babies need to grow as well as antibodies that boost their immune systems, thereby protecting against illness and helping to accelerate recovery.

The Progress Report estimates that about half of all diarrhoea episodes, and about a third of respiratory infections, could be averted by breastfeeding.

Yet, rates of exclusive breastfeeding during a child’s first six months remain low. In ten of the fifteen countries evaluated in the progress report, fewer than half of mothers exclusively breastfeed their children.

To increase breastfeeding rates, governments need to ensure that mothers receive the guidance and help they need.

That means training health workers; establishing community-level support networks, such as mother-to-mother groups; investing in behavioural-change campaigns; and creating a culture in which breastfeeding is welcome and encouraged.

The second critical intervention is improved water, sanitation and hygiene in homes and communities.

Globally, according to UNICEF, around 2.4 billion people still do not have access to modern sanitation, and 663 million do not have access to safe water sources. 

Many kids still lack clean drinking water, access to basic toilets and good hygiene practices.

Poor water quality and lack of reliable sanitation systems to treat human waste play a big role in spreading diseases. 

UNICEF reports that something as simple as hand washing with soap can cut rates of diarrhoea and respiratory infections by more than 40 per cent and 25 per cent, respectively.

By investing not only in systems to provide clean drinking water and sanitation, but also in educational programmes that encourage better hygiene practices and toilet use, governments can break a vicious cycle of diarrhoea and malnutrition that causes irreversible physical and cognitive damage.

The children they help are more likely to be able to attend school, and grow into healthy, educated adults.

The third key intervention is vaccination. 

Vaccines represent the most cost-effective intervention for preventing childhood illness, and they already exist for most common bacterial causes of pneumonia (pneumococcus and Hib) and for the leading causes of diarrhoea (rotavirus).

Yet, half of the world’s children live in areas where the pneumococcal vaccine is not available through a national immunisation programme, and only 15 per cent of the children in the world’s poorest countries have access to the rotavirus vaccine.

By making vaccines available through national immunisation programmes, governments can protect all children from the diseases that are most likely to harm or kill them.

Efforts to ensure that families take advantage of vaccination services, including by educating parents about their value, will also be needed.

Pneumonia and diarrhoea should not still be taking children’s lives. No single intervention will be enough. 

But the accelerated and coordinated implementation of the three interventions described here could go a long way towards preventing pneumonia and diarrhoea, especially for the most vulnerable children, enabling them to lead healthy, productive lives.
