Outline• Background and rationale

• Magnitude of Congenital and Genetic Disorders (CGDs) in EMR

• Interventions to reduce the burden of CGDs in EMR

• Discussion on next steps

Page 3: Prevention and care of Genetic and Congenital Disorders, including Preconception Care

Background and rationale

Under-5 mortality rate decreased by 48% over the past decade

Neonatal mortality remains high and represents 46% of the under five deaths in the Region

In the EMR, congenital and genetic disorders (CGDs) cause over 25% of neonatal mortality

Consanguinity rate reaches 20%–50% in some countries of the EMR increasing the birth rates of autosomal recessive disorders

Congenital disorders (birth defects)

“Any potential pathological conditions arising before birth –

whether evident at birth or manifesting later in life” (WHO)

Page 6: Prevention and care of Genetic and Congenital Disorders, including Preconception Care

Two main groups – environmental and “constitutional” congenital disorders

Page 7: Prevention and care of Genetic and Congenital Disorders, including Preconception Care

Total congenital disorders, births /1,000 if no intervention (baseline birth prevalence) by WHO Regions

The baseline birth prevalence of chromosomal disorders, congenital malformations and baseline single gene disorders is similar in all regions. EMR has the highest rate for consanguinity associated disorders. B Modell ,2016

Promoting Preconception Care (PCC) in EMR.2015-2016

-Reviewed PCC health needs -Updated evidence-based interventions

-Identified priority actions

-Defined PCC Regional core interventions based on evidence -Defined programmatic steps

-Agreed on PCC Regional core package & programmatic steps with partners

-Defined collaborative mechanisms

-Reviewed CGDs magnitude-Agreed on priority CDGs interventions-Proposed requirements for prevention and care

Interventions to reduce burden of CGDs at the preconception/premarital stage

Supplementation and fortification

Conclusion Newborn death is almost 50% the death of children

under the age of five in EMR Congenital disorders constitute 25% of total newborn

death Evidence-based, high impact interventions contribute to

high reduction of the burden of CGDs Disability remains a challenge and will increase with

improved survival Targeted policies and strategies are needed

Page 17: Prevention and care of Genetic and Congenital Disorders, including Preconception Care

Future steps

Update epidemiological status of CGDs at country and Regional levels

Establish a national committee for prevention and management of CGDs

Develop necessary policies and strategies to respond to CGDs

Prioritize evidence-based, high impact and cost-effective interventions

Strengthen measurement and surveillance tools in line with SDGs targets

Pillars for introducing and strengthening the interventions targeting CGDs

Increasing public awareness and
