Background
Anemia is a world-wide nutritional disease in children,the
harm of anemia in early childhood is extremely serious.
Although over the years the Chinese government has
taken various measures to control anemia,however,in
poor rural areas, especially in the western region anemia
remained high in children.Epidemiological factors of
children's anemia are complicated and changeable.

Objective

To understand anemia and iron deficiency status and
their correlates among children aged 6-23 months in
rural minority areas in Yunnan

Method

Questionnaire
to Caregivers

Anthropometric
measurements

Hemoglobin
measurements

Survey Methods

Page  6

Ferritin
measurements


Evaluation Method
Diagnostic criteria for anemia: Hb < 110 g/L (the Hb
was 4% more for each 1000 meters above sea).
Physical development of evaluation criteria: based-on
the WHO (2006) Recommendation, child weight-forage Z score (WAZ) <- 2 being as the low weight,
height for age Z scores (HAZ) <-2 being growth
retardation, weight for height Z-score (WHZ ) <-2
being as wasting.
Z score = (measured indicators - reference median) /
standard deviation of the reference standard.

Conclusion
The anemia prevalence rate among children in rural
minority areas in Yunnan is high
Mother Occupation is housework and farmer 　 feeding
Complementary too early or too late are risk factors of
anemia

Suggestions
►Parents’ nutrition knowledge and feeding guidance,
as well as health examinations during childhood need
to be strengthened
►Giving more children nutrition package
