assessing the effectiveness of nutrition education for mothers to reduce malnutrition for children under 24 months of age in soc son district, ha noi

INTRODUCTION
1. The urgency of thesis
Protein - Energy Malnutrition (PEM) in Vietnam often called
malnutrition. Malnutrition in general and stunting in particular is still
a public health significant problem in developing countries, including
Vietnam. According to the 2000 report of the Standing Committee on
Nutrition of the United Nations and Research Institute for the
International Food Policy (ACC/SCN/ IFPRI), about 30 million
newborns affected by the consequences of fetal malnutrition and
about 185 million children <5 years of age (34%) were stunting in the
developing countries; In 2005, still about 178 million children <5
years of age (32%) were stunted in developing countries.
In Vietnam, underweight rate of children under 5 years of age
decreased relatively rapidly and continuously from 1985 to 2000,
while stunting rate still high, especially in poor areas, overweight,
obesity and a number of non-communicable chronic diseases
associated with nutrition increased. In Hanoi, underweight rate was
decreased rapidly from a low level (18.7% in 2001) to a very low
level (8.6% in 2011), while stunting was not decreased but increased
(15.6% in 2001, 17.8% in 2011). Soc Son is a poor suburban district
of Ha Noi, with the high rate of malnutrition (stunting was 25% in
2007) due to many reasons such as low maternal educational level,
nutrition limited knowledge and practice. Therefore, many
intervention programs have been implemented, of which an
important solution is to build and deploy a pilot intervention by only
active education and communication. In this context, the study
1
namely “Assessing the effectiveness of nutrition education for
mothers to reduce malnutrition for children under 24 months of
age in Soc Son District, Ha Noi” has been conducted.
Study objectives:

1. To describe status of malnourished children under 24 months of
age and mothers’ knowledge and practices on child malnutrition
control at six communes in Soc Son district (2010).
2. To assess the effectiveness of interventions to improve knowledge
and practices of mothers on child malnutrition control at 3
communes in Soc Son district (2010-2011).
2. New scientific and practical contributions of the thesis
2.1. With the designed cross-sectional descriptive study on a large
enough sample size, updated technical and analysis of collected data
application in phase 1, the study has identified the malnutrition rate
of children under 24 months of age in 6 communes of Soc Son Hanoi
in 2010: underweight was at very low level classified by the WHO,
7.8 %, stunting at low level, 19.1% and wasting 3,9 %, all of these
are lower than national average. At the same time, it has specified
that right in a suburb of Hanoi, the knowledge; practices for child
malnutrition control, diet diversification, care of sick children,
personal hygiene of mothers with children under 24 months of age
were still very limited. This may be considered the new findings
about realities and the causes of child malnutrition in Soc Son.
2. In phase 2, the early long-term (12 months) intervention by only
active education and communication has had plausible conclusions
and recommendations which very useful for child malnutrition
2
control programs. These are the new scientific and practical
contributions to the specializations of Social hygiene and health
organization, and Community Nutrition.

OVERVIEW
1.1. Nutritional status and child malnutrition
Protein - Energy Malnutrition (PEM) includes 3 forms: underweight,
stunting and wasting of different levels, mild, moderate and severe.
According to WHO 2005, 32.5% of children under 5 years of age in
developing countries are stunted, the 2 highest prevalence areas were
Africa and Asia (33.8% and 29.9%). From 1980 to 2000, the
estimated number of stunted children was reduced by approximately
6.2 million. According to WHO and The Lancet January 2008, some
40% of countries have stunting rates higher than 40%. Problem is
that the stunting rate was highest in the lowest quintile population. In
Vietnam, the prevalence of underweight from 51% in 1985, dropped
to 33.8% in 2000, fell sharply to 19.9% in 2008. Wasting was 8.6%
in 2000; fell below 5% in 2008. Stunting decreased from 56.5% in
1990 to 36.5% in 2000 and remained high at 29.3% in 2010 and there
is a big difference between regions.
Figure 1.6. Vietnam malnutrition rates among under five
children 2000 – 2013

Figure 1.6 showed the rate of child malnutrition 2000 - 2013.

Immediate causes of malnutrition are identified including
inappropriate eating and disease. Underlying causes includes
household food insecurity, inadequacy of maternal and child care
services, knowledge of caregivers, family care, water supply and
sanitation and unsanitary housing conditions. The basic causes of
malnutrition is defined political structure, socio-economic and
cultural factors, potential resources (environment, technology,
humans), including poverty, backwardness, underdevelopment,
including economic inequality, especially economic crisis.
Malnutrition has been found leading to obvious heavy consequences
on the child intellectual development, behavior, learning ability,
height stature, and work capacity of adulthood, chronic diseases and
influencing to the next generation.
1.2. The solutions for malnutrition control
Global focus on 3 main solutions: 1) Increased nutrients intake (both
quality and quantity), including protein and energy supplements for
pregnant women, strategies to encourage breastfeeding, quality
improvement of complementary foods; 2) Supplementation of
micronutrients, including iron, folic acid, vitamin A, calcium for
pregnant women; Iodized salt supplements, vitamin A and zinc for
infants; 3) Reducing the burden of disease.
In Vietnam, malnutrition prevention measures have been
implemented during war time, but the effect was very limited. From
the last decade of the XX century to the present, Vietnam has
developed and deployed the National Target Program for Protein
5
Energy Malnutrition control since 1994, Program for micronutrient
deficiency control, the National Plan of Action for Nutrition 1995-
2000, National strategy for Nutrition 2001-2010 and National
strategy for Nutrition 2011-2020 with a vision to 2030. Nutrition

education and communications has always been regarded as a key
solution through the programs’ plans and strategies’ framework.
However, the activity found to be heavily on the put-forms or
movements, just in some kinds of campaign, but not really the
practical operation, resulting in low effectiveness and lack of
sustainability.
1.3. Education and communication research for malnutrition
control
Many studies to change knowledge, attitudes and practices (KAP) for
control of micronutrient deficiencies and malnutrition have been
deployed in the region, in the world and in Vietnam. However, most
of these studies were coordinated with food or micronutrients
supplements. The idea of our study is based on the theoretical and
practical basis: active nutrition education and communication can
change the mothers’ nutrition and child care habits, then the children
will get improved diets, indirectly reduce the rate of child
malnutrition; At the same time, the mothers ‘nutrition habit/ practice
changes affect themselves before and during the subsequent
pregnancy to actively prevent fetal malnutrition and low birth weight.

After 12 months of intervention, maternal knowledge about how to
identify stunted children, the causes of child malnutrition has been
markedly improved. Similarly, the rate of mothers who know about
proper diet for pregnant women as well as for diarrhea children
increased.
The mothers’ practices on child growth monitoring, proper feeding
for the sick/ diarrhea children, complementary feeding and personal
hygiene found significantly improved after the intervention and
compared with the control group.

The research results show that, after the intervention, knowledge
scores was 63.6±10.5 and practices 67.6±12.1, higher than that at T0
(16.6±12.1 and 41.2±10.1) and the control group (26.7±13.6 and
38.1±16.3). The knowledge on diversified meals and appropriate
supplement food preparation in the intervention group, 64.6±21.7
higher than that at T0 and in the control group at T12 (29.2±12.3) and
(19.8±9.9). The score for diversified meals and supplementary food
preparation in the intervention group were also higher that at T0 and
control one at T12.

DISCUSSIONS
4.1. Actual nutrition status of children under 24 months of age
and mothers’ nutrition knowledge and practices at six communes
of Soc Son district in 2010
4.1.1. Actual nutrition status of children under 24 months
The rate of underweight (W/A<-2SD), stunting (H/A<-2SD) and
wasting (W/H<-2SD) of children 0-24 months of age in six
communes Soc Son district in 2010 was 7.8%, 19.1% and 3,9%,
respectively. These rates are not different between the 3 projected
intervention and control communes (p>0.05). However, the rate of
malnutrition is lower than that of children under 5 years of age in Soc
Son 2001 and 2006 (underweight 31.9% and 21.2%, stunting 33.3
and 27.9% and wasting 7.9 and 7.5%) and lower than the national
figures 2011 (16.8% underweight, 27.5% stunted and 6.6% wasted).
However, compared with other studies in recent years in other areas
of North Delta, malnutrition rates of children under 24 months of age
in our study are still of relatively high and comparable to the difficult
regions. This is consistent with some elements of socio-economic
conditions of Soc Son - a suburban district but essentially remains a

poor rural area with agriculture as the main economic, poverty rate
also high at 20% in recent years; the socio-economic development
remains equal to or lower than many other rural areas. According to
FAO/WHO, by 2012 the rate of worldwide undernourished children
under 5 years of age has decreased, but there was still 162 million
children with chronic malnutrition (stunting), 51 million suffered
from acute malnutrition (wasting); More than 2 billion people lack of
18
micronutrients such as vitamin A, iodine, iron and zinc, whereas
overweight and obesity in both children and adults increased rapidly.
In Vietnam, according data of the National Institute of Nutrition,
underweight rate decreased rapidly: from high level classified by the
World Health Organization (51, 5% in 1985) to average (18.9% in
2009). Nutrition monitoring data of the National Institute Nutrition
recently showed that in 2012 and 2013 the national average rate of
child malnutrition continued to reduce (underweight 16, 2 and 15.3%,
stunting 26.7 and 25.9%, wasting 6.7 and 6.6%). Prevalence of child
malnutrition in Hanoi 2012 and 2013 was 8.1 and 7.0% underweight,
21.9 and 15.5% stunting and 5.5 and 2.8% wasted, respectively. It
can be seen, in recent years, reducing malnutrition rate is very slow.
A surprising thing is that child stunting in Hanoi 2012 increased to
over 20%, a high level according to WHO, to be problem of
continuing concern.
4.1.2. Current status of knowledge and practices to control child
malnutrition and diet diversification of mothers with children
under 24 months
The cross-sectional study in 2011 showed that Soc Son mothers’ both
knowledge and practices on child malnutrition control measures and
diet diversification are poor. On a scale developed by the research
itself, knowledge score to control malnutrition of mothers was

classified as poor (20.6±12.8), while their score on practices as
average (40.1±12.1), most mothers did not have good scores.
Similarly, on the meal diversification and supplementary food
preparation, the mothers’ knowledge scores (25.2±10.3) and practices
(45, 3±12, 6) were very low, classified as the weak and average.
19
4.2. Effect of the intervention to mothers’ improved knowledge
and practices for child malnutrition control and diet
diversification
4.2.1. Effect of the intervention to change mothers’ knowledge and
practices on child malnutrition control
After 12 months of intervention, the percentage of mothers who
know how to recognize their undernourished children, the causes of
malnutrition, the contents of appropriate breast feeding, feeding sick
infants, nutritive values of some green leafy vegetables and yellow/
brown or red fruits, varied supplementary food preparation
significantly increased in the intervention group.
Effect to changing mothers’ practices to control child malnutrition:
After intervention, the percentage of mothers who monitored their
child weight, height and gave properly diet to sick children,
supplementary feeding, personal hygiene, especially safe child
manure handling and hand washing improved markedly.
4.2.2. Effect to change mothers’ scores on knowledge and practices
to control child malnutrition and diet diversification
After intervention, mothers’ knowledge and practices score on child
malnutrition control, diet diversification were higher (p<0.001) in the
intervention group compared with T0 and control one at T12. The
effective and real effective index of the intervention group found
significantly higher. The result is similar to the study of Hung Pham
Hoang, Thu Mai Ho, Nam Phuong Huynh conducted in some

researches on different subjects with different goals/ objectives.
20
Thus, the active education and communication intervention in for
mothers with children aged from birth to <24 months have markedly
improved mothers’ knowledge and practices on child malnutrition
and diet diversification.
4.2.3. Effect of intervention on the nutritional status of the children
The increase in weight was significant at 6 months after the
intervention, but the absolute height increased significantly only after
12 months. The change in Z-scores at T6 and T12 in the intervention
group tended to better than the control one, however, significant
differences are observed only at T12 with p<0.05 for WAZ and
WHZ, p<0.001 for HAZ. After 12 months the intervention had an
indirect impact to lower malnutrition rate. Due to weight improved
sooner than height, intervention effective index in lower wasting rate
is earlier and highest, 74.2% followed by underweight, 41.6%, and
the lowest and longer is reduce stunting, 32.8%. This fact proves that,
stunting control is a hard work, requiring early, comprehensive and
long-term intervention.
Over the last two decades, many national and city programs has been
deployed in Soc Son, contribute to improve mothers’ knowledge and
practice and promote the produce and use of diverse food sources.
Our study has clearly been shared the of the said programs’
effectiveness, especially the use of diverse food sources in place to
improve the children’s daily meals promoting weight, height growth
and indirectly lower the rate of child malnutrition.

CONCLUSIONS
1. Actual nutrition status of children under 24 months of age and
nutrition knowledge, practices of mothers at in communes of Soc Son

District 2010:
The percentage of malnourished the children under age of 24 months
in 6 communes of Soc Son: stunting was at low level (19.1%)
classified by the World Health Organization, while underweight was
at very low level (7.8%) and acute malnutrition, wasting was also low
(3,9%). All of these rates are lower than the national average.
The knowledge on child malnutrition control and practices on the diet
diversification of mothers with children under 24 months of age are
still insufficient. The mothers’ practices on personal hygiene and
child sick care still unsatisfactory.
2. Community intervention trail by active education and
communication has markedly impacted to the mothers’ nutrition
knowledge and practices, the children’s weight, height growth, Z-
score index and nutritional status:
Mothers’ nutrition knowledge and practices on diversified meals and
supplementary food preparation were significantly improved:
average knowledge score of the intervention group at T12 were
significantly higher (p<0.001) than that of the control one
(64.6±12.3) and of the same group at T0 (19.8 ± 21.7 versus 29.2
±64.6). Similarly, the practice score of mothers in the intervention
group were also higher at T12 (p<0.001) (67.6±8.4 vs. 43.3±16.1)
and T0 group (43.9±11.4). The effective index for knowledge,
22
practices significantly higher (p<0.01) and the real effective
intervention index are high (49.8% and 57.6%, respectively).
Mothers’ knowledge and practices on child malnutrition control was
significantly improved: the average knowledge score (63.6±10.5) and
practices (67.6±12.1) in the intervention group higher at T12
(p<0.001) compared with T0 and the control group. The effective
index for knowledge, practices on child malnutrition control

significantly higher (74.8%) and high real effective intervention
index (61.0%).
Intervention impacts to improved weight and height growth: at T6
and T12, the children’s weight gain of intervention group (2.1 kg and
3.3 kg) was higher (p<0.05) compared with control one (1.8 and 2.8
kg); The height gain of the intervention group (7 cm and 12.6 cm)
was higher than the control one (6.4 cm and 11.7 cm) but only
significant at T12 (p<0.01). The changes in the intervention group
were also significantly only at T12 with WAZ and WHZ (p<0.05)
and HAZ (p<0.001).
The real intervention effective index to decrease child malnutrition
after 12 months for all 3 forms had positive values: highest for
wasting (74.2%), followed by underweight (41.6%) and the lowest
for stunting (32.8%). This proved to reduce stunting is hard work,
requiring early, comprehensive and long-term interventions.

RECOMMENDATIONS
1. Education and communication to change nutrition behavior in
frame work of other existed intervention programs’ activities found
to be a "long-term" and feasibility solution needs to be considered to
comprehensively coordinate with other interventions to apply and
expand to other similar socio-economic condition areas, especially
health and nutrition collaborators network.
2. Local Authorities, health sectors should actively steer unified and
coherent implementation of interventions to prevent malnutrition for
children early, since they were in the womb, after birth to <24
months of age, as recommended by the World Health Organization.
3. To sustain effectiveness, after the intervention program/ project,
the localities should continue to strengthen efforts of collaborators as
well as subjects to promote their responsible contributions in many

forms, such as rewards, gifts, invitation to attend the big vents or
participation in community activities/ social work, etc.
