EPIDEMIOLOGICAL DATA

   
Goiter  
Most Recent Goiter Survey  
Date: February - August 1994
Groups Surveyed: Children 8-10 yrs.
Sample Size: 3260
Sampling Method: A national survey covering a total of 45 districts.  A total of 163 primary schools were randomly selected from the 15272 primary schools in Kenya at the time of the study.  For each school, 20 children (10 girls and 10 boys) were randomly selected to represent each school.
Other Survey A multicenter study (1995) that covered Kericho, Kiambu, and Nairobi.

POLICY AND LEGISLATION

 

Legislation on IDD

    

IDD legislation was passed in Kenya in 1978.  The legislation covers all salt produced for human consumption.  The year of enactment was 1978, but in 1988, there was a revision on the legislation.  Specifications for edible salt are reviewed regularly (latest revision was in September 2000) by the Kenya Bureau of Standards.  Legislation of animal salt is not yet in place.

    

Iodization of salt is mandatory.  The mandated level of iodization is 168.5 mg/kg of salt, or 100ppm.
Government Agency to Address IDD
    

The government agency that deals with the monitoring of IDD is the Kenya Bureau of Standards (KEBS)

    

Contact information:  Mr. Tom Olielo, Standards Division, P.O. Box 54974, Mombasa Rd., Nairobi

   
     

PROGRAM DATA

Supplementation
     Oral supplementation with iodized oil capsules is not currently used.
Fortification
Production and Importation of Salt
    

There is iodized salt production.

    

The total annual national production of iodized salt was ~270,000 metric tons in 2001.

    

The intended level of salt iodization at the point of production is 100PPM.

    

Large-scale salt iodization started in the 1970's.

    

There are currently five iodized salt producers.

    

Potassium iodate is used to iodize salt.

    

Vacuum dried packing is the packaging method used.

     Less than 1% of iodized salt is imported from Holland, Israel, etc.
    

The intended level of iodization for imported salt is100 ppm.

    

Salt iodine content at production level is assessed by routine titration.

    

*   The salt production that achieves the target iodine level was estimated at >90% in 2000, but wide fluctuations of iodine levels in salt was the problem.  This was assessed via surveys.

    

*  There are no other measures of fortification with iodine in widespread use.

Retail
   

*  The average retail cost of salt is ~12 Kenyan shillings per kilo.  There are minor regional differences, no more than 5% variation.

Household Consumption
     The estimated percent of adequately iodized salt consumed, as a national average is 92%.

Other Programs Related to Control of IDD
Mass Media Campaigns
    

Advocacy on electronic and print media is done on an ongoing basis.  Salt manufacturers are mainly involved in print media advocacy as well as radio spot messages to inform consumers about importance of consuming iodized salt.  Since 2001, UNICEF has started supporting IDD month activities in October of each year.  IDD month brings manufacturers, schools, and the Ministry of Health together in a mass media campaign to sensitize the public on all relevant issues on IDD.

Community-Based Programs

     The Ministry of Health with support from UNICEF has trained salt monitors for district level monitoring to ensure retailers and households understand the importance of IDD control through salt iodization.  The monitors use rapid testing kits in the field and make reports to head office for follow-up if non-iodized salt is found.  Advocacy messages on the importance of consuming iodized salt and storing it properly once purchased are communicated through mobile cinemas in rural communities.  The IDD control project is a nation level activity.

MONITORING
 
Salt Iodine
Current monitoring activities for iodine levels in salt
     Monitoring is done using rapid testing kits of salt samples at household, retail, and wholesale levels.  Monitoring at the factory level is done via random sample collection by the Standards Officers through titration methodology. 
     The IUE/Goiter and KAP survey will be repeated before the end of 2002.
     UNICEF supported Rapid Testing Kits are given to schools and to community level public health technicians to sensitize officers and children on monitoring aspect of IDD and salt iodization.
    

IDD Indicators

     The lab facility for biochemical measurements is the National Laboratory.  This was renovated with support from UNICEF in 1990/1991 to facilitate IDD biochemical assessments.
     There is no routine monitoring of goiter rate.  However, occasionally there are visits to monitor number of cases (surgery, etc.) related to IDD that have been handled by some rural as well as referral clinics.
