Nutritional Status of Filipino Children
and Selected Population Groups: 2005 Update
INTRODUCTION
Anthropometry
Since the First National Nutrition Survey (NNS) of FNRI-DOST in 1978
and the 1989/90 Update of the Nutritional Status of Filipino Children, the survey
results are vital components in the formulation of national and sub-national policies,
plans and programs for the nutrition and related development sectors. These plans
and programs include the Medium-Term Philippine Plan of Action for Nutrition
(MTPPAN), Medium-Term Philippine Plan of Action for Children (MTPPAC),
Poverty Alleviation Programs, among others. It is also being used as gauge to the
country’s progress on achieving the Millennium Development Goals (MDG), the
country being a signatory to the UN Millennium Declaration of 2000.
This Facts and Figures 2005 covers the anthropometric data generated from
the 2005 Survey of the Nutritional Status of Filipino Children and Selected Population
Groups which is a follow-up to the 2001 Update of the Nutritional Status of Filipino
Children and the 2003 National Nutrition Survey. It provides reliable national estimates
on the nutritional status of zero to 10 year-old children and 11 to 19 year-old
adolescents, pregnant women and lactating mothers.
The 2005 Updating Survey covered all the 17 regions and 79 provinces,
excluding Batanes. The sample totaled to 12,560 individuals, which may be broken
down into 3,560 preschool-age children (zero to five years), 3,264 school-age children
(six to 10 years), 1,273 pre-adolescents (11 to 12 years), 3,114 adolescents (13 to 19
years), 360 pregnant women and 989 lactating mothers. A total of 5,774 males and
6,786 females participated in the survey.

Using the standard techniques of anthropometric measurements, the height,
weight and recumbent length (for children less than two years old) were measured
for each subject by locally trained professionals in the region.
The weight and height measurements of the children zero to 10 years of
age were assessed to determine nutritional status, using the International Reference
Standards or the anthropometric references established by the NCHS/WHO (IRSNCHS, 1997) as shown in Table A.
The study did not have index of thinness among the nine to 10 year old
children primarily because of the limitation of the weight-for-height table of the
NCHS-WHO where heights of children beyond eight years old were not available.
The weight and height measurement of the pre-adolescents and adolescents
11 to 19 years of age were assessed using Body Mass Index-for-Age (Must, 1991)
as presented in Table B.

The weight and height of pregnant women were assessed using the criteria
established for pregnant women by Magbitang et al., (1988) (Table C). Using the
cut-off points, pregnant women whose weights fell below the 95th percentile of the
reference were considered to have a high risk of delivering low birthweight (LBW)
babies.
For the lactating mothers, 20 years old and over, the Body Mass Index
(BMI) for adults was used (NCHS/WHO, 1978). The BMI-for-Age was used for
adolescent lactating mothers (Table D).

Iodized Salt Survey
The 2003 NNS results also showed general improvements in household
utilization of iodized salt, but the rate of utilization at the national level (47.9%) is still
short of the country’s Universal Salt Iodization (USI) target. There was also a
dramatic improvement in median UIE among six to 12 years old children, from 71
µg/L in 1998 to 201 µg/L in 2003, and correspondingly, a dramatic shift in distribution
of UIE values among the children such that a significant proportion has high UIE
levels that may be indicative of very high iodine intake. There is, therefore, valid
concern to ascertain the level of iodine in iodized salt at the household level, which
will provide the scientific basis for any warranted review of the iodization level now
prescribed under the ASIN Law.
The iodized salt survey has two components. The first component is the
survey on awareness and usage of iodized salt. The other component is the testing
of iodized salt using rapid test kit and WYD iodine checker machine.
1. Awareness and Usage of Iodized Salt
A face-to-face interview with the mothers or responsible adults of the
household regarding the usage and awareness of iodized salt was conducted by
the locally trained professionals. A structured and pre-tested questionnaire
body_june20.pmd

FACTS & FIGURES
was used in gathering the information. A total of 5, 345 households were covered in
the survey.
2. Iodine Testing
Using Rapid Test Kit
In additon, on-site testing for the presence of iodine in household salt using
the Rapid Test Kit was also simultaneously done with the interview. Respondents
were requested to bring a small quantity of their household salt in the assembly
area for the testing.
Using WYD Iodine Checker Machine
Quantitative measurement of iodine in household salt was also conducted
to check whether the desired levels of 40-50 ppm, set by ASIN Law, was met.
Only a sub-sample of 3,050 households, representing 25 percent of the full sample
of the MS, was included. The mothers or responsible adults of the households were
requested to bring about 100 grams household salt to be placed in the polyethylene
containers that were provided a day before the interview. Collected samples were
placed in black plastic bags and transported to the FNRI in Manila for laboratory
analysis. Iodine in salt was analyzed using the WYD Iodine Checker machine
under laboratory conditions.

The overall trend indicate that undernutrition remains to be the
overriding problem among the zero to five year-old and six to 10
year-old children and still need to be the priority concern.
The increasing magnitude of overweight among the age group need
not be ignored due to associated risks such as cardiovascular
diseases and other health-related diseases during childhood.

In both sexes, 16 in every 100 adolescents 11 to 19 years are
underweight.
•
While for overweight, there are the same number of male and female
adolescents who are overweight at five in every 100 adolescents.
•
Adequate nutritional status is an important concern to adolescents
because of the increased nutritional need to support growth and
development during this period. In addition, adequate nutrition
especially among the female adolescents is an essential condition in
preparation for pregnancy in later years.

1.6 Trends in the Nutritional Status of Adolescents, 1993 to 2005
•
Looking at the trends in the nutritional status of the 11 to 19 year-old
children from 1993 to 2005, the prevalence of underweight practically
did not change (15.8 vs 16.0) during these periods.
•
Overweight, on the other hand, had increased twice from 2.4 in 1993
to 4.8 in 2005.
•
Considering the gender differences, underweight among the 11 to 19
year-old males decreased between 1993 and 2005 from 21.6 to 20.5
percent (1.1 percentage points). However, among the females,
underweight increased by 1.6 percentage points from 9.5 percent in
1993 to 11.1 percent in 2005.

1.7 Pregnant and Lactating Women
1.7.1 Pregnant Women
•
•
Among the pregnant women, 72 in every 100 are considered not
nutritionally at-risk and 28 are nutritionally-at-risk.
Between 2003 and 2005, there was 1.8 percentage points increase
in the proportion of nutritionally at-risk pregnant women from 26.6
to 28.4.

•
Underweight pregnant women are more likely to deliver low birth weight
babies, who in turn become vulnerable to undernutrition, poor health and
delayed psychosocial development.
The results, therefore, present a challenge to nutrition planners and program
implementers to strengthen programs for pregnant women to sustain the
reduction of undernutrition among young children.
1.7.2 Lactating Mothers
•
•
body_june20.pmd
Among the lactating mothers, 66 in every 100 have normal weight, 14 are
underweight and 20 are overweight for their height.
Between 1998 and 2005, overweight prevalence had increased by 6.2
percentage points from 13.6 to 19.8 or a yearly increase of 0.89 percentage
point.

2. AT THE REGIONAL LEVEL
2.1 Preschool-age Children (0 to 5 Years)
•
NCR is the only region that has much lower prevalence of underweight
zero to five year-old children as compared to the national estimate (16.2 vs.
24.6).
•
ARMM, on the other hand, has the highest underweight prevalence with
38.0 percent compared to the national estimate. Prevalence rates of the
other regions ranged from 19.7 percent (Central Luzon) to 35.8 percent
(MIMAROPA).
•
Based on the cut-off used by NSO, those regions with coefficient of variation
(CV) less than 15 percent are reliable estimates for the region.
•
For underweight prevalence, almost all regions except CAR (23.0), Cagayan
Valley (17.2) and SOCCKSARGEN (15.0) have CVs less than 15 percent,
which indicate that the estimates are reliable for these regions.

are aware), more than one-half or 59.0 percent claimed to be users of
iodized salt.
Other results revealed that:
•
The most common sources of information on iodized salt are from health
personnel and the television
•
Grocery/supermarket/drugstore and market/’talipapa’ are the common
market source of iodized salt
•
According to households, iodized salt is usually used as table salt and for
cooking
•
Households’ perception on the cost of iodized salt is just right and the most
common packaging is in package with label

2. IODINE TESTING
2.1 Using Rapid Test Kit
•

•
•
Using the rapid test kit, results revealed that 75.4 percent (as compared to
56.4 in 2003) of the total household salts tested had positive reaction to
potassium iodate.
The 24.1 percent of the total households have salt negative to the test, i.e
the salt either had no detectable iodine as potassium iodate, or had iodine
but in potassium iodide form, or was confirmed to be ordinary non-iodized
salt.
Among households who claimed using iodized salt, only 88.7 percent had
positive reaction indicating that iodine in salt is in the form of potassium
iodate.
The remaining 11.0 percent, probably had iodine but in iodide form or even
with iodine but in very low undetectable level.

Majority of the household salts (65.1 percent) was iodized, that is, five and
above ppm.
Only 44.5 percent of salt samples were found to have iodine at > 15ppm.
About 20.6 percent of salt samples were found to have 5-14.9 ppm of
iodine at the household level.
In addition, 35 percent of household salts have no iodine content at all in
their salt (0-4.9 ppm).

There were 18.3 percent of the household salts that positively reacted to
RTK but has no iodine content when analyzed by the WYD Iodine Checker
machine.
On the other hand, there were 81.8 percent of household salts that were
correctly identified by RTK test to have iodine, the levels of which ranged
from 5.0 to >60 ppm.
•
In addition, those 56.2 percent, which tested positive from RTK, had sufficient
to high iodine content.
