									        Jordan’s Micronutrients Issue:
The Dilemma of Search for Effective Intervention

       Ibrahim M.D Khatib    (MSc , PhD)

Over many years, countries in the East Mediterranean
consistently overlooked under-nutrition as a probable health
threat to the community.

Today, few of these countries have discovered that no single
developing community may claim to be off the hook of
malnutrition, particularly hitting at the risk groups level.

Jordan has been one of those few EM-countries

       The most common health problem in developing countries
       Even in milder forms, it weakens the immune system
       Cause of diarrhea / ARI frequent / severe attacks
       Increases mortality in childhood (60 % of Global Rate)
       Causes are :
                       1. Direct   - inadequate access to food
                                   - inadequate intake of micronutrients,
                       2. Indirect - inadequate health care of mothers and children,
                                   - inadequate health services, and
                                   - unhealthy environments / poor hygiene

Jordan - Public Nutrition
 Facts and Chalenges
                  Adulthood Problems

Type 2-diabetes
    prevalence in middle age is above 20 %

CVD : Cardio-Vascular Disease
    prevalence is on the rise
                    Childhood Problems

Jordan is free from primary Malnutrition ( p-PEM)
Only secondary Malnutrition (s-PEM) prevails;
s-PEM signals inadequate tissue metabolization of nutrients
s-PEM is commonly attributed to:
  - Disease : e.g. frequent diarrheas / malabsorption / infections
   - Micronutrients – deficiencies (MNDs)
                      In Jordan…
         MNDs Are No Longer a Hidden Hunger

MNDs are significant causes of s-PEM in Jordan

Iodine, Iron, Zinc, and Vitamin A deficiencies : endemic

Stunting: remains the devious face of s-PEM

Anemia due to IDA and / or VAD : prevalent
              Significance in Childhood

Frequent diarrheas and infections / suppressed immunity
Stunting / Subnormal child growth pattern
Low IQ / compromised cognitive development
Poor performance / school achievement
Weak muscles / decreased work potential
Increased risk of death
            MNDs : Selected Outcomes

Iodine Deficiency Disorders (IDD)
  - mental deficiency
  - Physical anomalies
Poor Learning

Non-ocular VAD
Depressed immunity: infections / diarrhea & ARI
Physical growth deficiency
Predisposition to IDA
Ends with visual impairment / Nutritional blindness
            VAD, IDA, IDD
         International Reports

  Reduced learning capacity / intelligence
Population loss estimate = 10–15 I.Q. points

     Accomplished Surveys

Community Research For Advocacy
          Zinc Deficiency and Stunting [1,2]

Supplementation at infancy prevented growth stunting
                         MOH- IDD Surveys   [3,4]

IDD Prevalence
- by goiter assessment : 37.7 %
- by urinary iodine excretion > 50 %
   (median iodine excretion = 4 mcg/l)
IDD is a public health problem in Jordan;
Severity is highest in south / lowest in middle areas;
Intervention by salt-iodization started in 1996;
Program evaluation result (in 2000): satisfactory.
           MOE- Year 2000 School Surveys    [5,6]

Baseline prevalences among poor young school children:
 - 19.9 % for stunting,
 - 18.8 % for anemia,
 - 21.8 % for VAD.
Supplement: a daily snack + one 200,000 i.u.vitamin A capsule
Intervention improved all, EXCEPT stunting

Conclusion: VAD in school children is a public health problem.
               AlSaafi Schools Study, 2002 [7]

Approach : controlled interventional study ( 3 study groups)
Poorer villages of the disadvantaged AlSaafi district.
VAD prevalence : 35.3 %
Snack meal together with VA capsule made growth improvement;
A National Vitamin A Program should phase in.
             Conclusions on School Nutrition

Poverty linked-sub-clinical - VAD is confirmed as a public health emergency and
seems to be endemic in under-developed districts.

Impact of high domestic consumption of vegetables and fruits offset by
households concentrating on the carotenoids-poor items.

Statuses of vitamin A and E correlate strongly, suggesting a common defect in
fat solubles - absorption mechanism .

For poor young school children, the snack is essential for the VA capsule to
induce a significant improvement of serum VA levels.
Surveys on U5y - children
   North Badia survey - Year 2001 [8]

Prevalences Among Bedouin U5y – Children:

    Stunting ≈ 20%,
    anemia ≈19 %, ,
    non-ocular VAD ≈ 22%
Jordan Population and Family Health Survey   [9]
               DoS- Year 2000

 Anemia is prevalent at rates of :

   34% in U5y - children.

   65% in the 10-11 months children
           MOH–National Nutrition Study [10]
                         Year 2002

           Women in the child bearing age

Anemia               > 30 % ; (Hb <12 g/dl)
Iron deficiency (ID) > 40 % ; (low ferritin)
ID anemia            > 20 % ; (low Hb & ferritin)
   MOH–National Nutrition Study    [10]
                Year 2002
              U5y - children

Anemia = 20.1 % ; (Hb <11 g/dl)
Iron deficiency (ID) = 26.1 % ;
Iron deficiency anemia (IDA) = 10.1 % ;
Vitamin A deficiency (VAD) = 15.1 %

Other factors contribute to the national nutritional problem
VA status and anemia always correlated with:

 - Maternal education
 - Consumption of animal based food
 - Socio-economic status

                    Upon a Royal Decree….

The Jordan-government implemented in February 2003, a national
program aiming at the universal distribution of a daily multi-vitamin
& mineral supplementary tablet for every school childr in Jordan


The Jordan- High Commission on Nutrition recommendation is for
the switching from tablet - supplement distribution to food (flour)
fortification to secure higher coverage for other risk groups
The Pending Questions

Shall Jordan continue expanding in wheat
flour fortification to include vitamin A ?
If not, what will be the alternative option?

Shall Jordan consider adding some other
micronutrients to the premix ?
If yes, what are these ?

         Measuring Impact of Intervention
              Standard Indicators

Valid indicators are established to assess progress toward
achieving elimination of vitamin A and iodine deficiencies

In ID surveys, Hb and SF consitute a useful combination for
use as a tool to assess progress toward achieving alleviation
of iron deficiency anemia (IDA)

No single standard indicator exist for ID diagnosis
