Current Iodine Deficiency Disorder Situation
Population
Population: 59.78 million
Population growth rate: 0.21%
Population < 15 years: 18.7%
Birth rate: 11.34 per 1000
Life expectancy at birth: 77.99 years
Infant mortality: 5.45 per 1000
Prevalence of Goiter/ UIE
Median urinary iodine: 141 mcg/L.
Urinary iodine reported as 141 mcg/L. In 1990, excretion 73 mcg/g creatinine in summer and 98 mcg/g in winter.
Goiter historically common in middle and western part of England and Wales . Surveys as late as 1958 showed goiter prevalence up to 40% in girls, but prevalence subsequently declined in a 1990 survey in a previously iodine deficient area showed a mean thyroid volume of 5.5, in schoolchildren, aged 9-11, a normal volume for iodine sufficiency.
Newborn TSH levels comparable to iodine-sufficient regions
Almost all iodine intake comes from foods, and only 2.5% from iodized salt. An average daily intake of 255 mcg/person/day has been calculated.
Iodized salt Coverage
Household iodized salt use: unknown, but low
Salt Situation Analysis Production
No data
Consumption
- Estimated daily per capita salt consumption: no data
- Estimated % of all salt consumed by people which is adequately iodized (household level): no data
Iodine Procurement and Utilization
Iodized salt is available, but not produced locally and there is little information on its consumption.
Universal Salt Iodization Program
Information, Education, Communication (IEC) Activities
Legislation
- Legislation: None.
- Legislation for Animals: No ne but iodine is added to animal feeds, which appears in milk and milk products, and may be increased by iodophors.
- Year Enacted: n/a
Program Monitoring and Evaluation
No official program or surveillance. Periodic studies by Medical Research Council decades ago. Occasional information from research studies.
Other Interventions
None
Key Lessons Learned
Challenges and Constraints
