DISCUSSION
1. Relationship between suitability energy intake and
nutritional status
The results showed that there is a significant correlation
between suitability of energy
intake against undernutrition status (p = 0.000 and 95% !" #.9$0
to 1#.1& (.#51'' this )eans
that the students who ha*e the appropriate nu)ber of calories
likely to ha*e a nor)al nutritional
status that is e+ual to .#51 ti)es the odds co)pared to students
who ha*e the a)ount of energy
intake that does not fit. This is consistent with pre*ious
studies conducted Restiani in ,-
-uha))adiyah /akarta #1 which states that the eistence of a
significant relationship between
energy intake and nutritional status (Restiani 01'. The
i)balance between energy intake with
nutritional re+uire)ents affecting the nutritional status of a
person. hysical acti*ity and
eercise which is not balanced with energy consu)ption can lead
to abnor)al weight (-23

negati*e balance resulting in
underweight than it should be (ideal' (l)atsier 005' This is in
contrast with a pre*ious study
conducted by 6lau in ,- 7egeri 1 6okap 6ulon rogo 8ogyakarta
which states that there is no
relationship between energy intake and nutritional status (6lau
8 et al 01'. This is because

@on osco -anado which states that there is a significant
correlation between the intensity of
physical acti*ity and nutritional status (! sho*e 01'.
Aarious ade+uate facilities cause )otion
and acti*ity is li)ited (3udha 00&' resulting in an
unbalanced energy ependiture (by lack of
physical acti*ity' that can lead to weight gain or
o*ernutrition and applies also to the contrary
(3idayati et al 010'.
#. Relationship between suitability of energy intake and
physical acti*ity and nutritional status
ased on the results of analysis has indicate that the
suitability of the energy intake
affects the status of undernutrition while physical acti*ity did
not affect the nutritional status.
This )eans that if the a)ount of energy intake that enter the
body does not correspond to the
a)ount of energy re+uired intake the nutritional status is
likely to be less.
!f ecessi*e energy intake and energy ependiture is not )atched
by a balanced (with less
physical acti*ity' it will lead to weight gain and applies
also to the contrary if the physical
acti*ity is )ore and it did not balanced with enough energy
intake it can lead to weight loss
(3idayati et al 010'.
Bight physical acti*ity is done with intensity below 150 )inutes
per week while )oderate
physical acti*ity is done with the intensity of 150;#00
)inutes per week.
The weakness of this study a)ong others data collection with
+uestionnaires and inter*iews are
subCecti*e so that the correctness of data relied hea*ily on the
honesty and the ability to
re)e)ber each respondent in addition to the >> respondents
said there were gi*en an allowance
of Cust enough to transport to co))ute to school $0 respondents
on a diet $9 respondents were
not happy with the food ser*ed at houses and ## people say that
itDs because of econo)ic factors.
Bi)itations of ti)e collecting data fro) all respondents thus
affecting the accuracy of the data
collected. ?urther research is needed on the factors that
influence the incidence of )alnutrition
a)ong school children eg stress factors the factors underlying
disease and others.

?ro) the results and discussion that has been described can be
deduced as follows"
a. There is a relationship between lack of energy intake and the
incidence of )alnutrition a)ong
se*enth grade students in ,-7 6ediri and -Ts 7 6ediri with a
*alue of p = 0.000.
b. There was no relationship between physical acti*ity and
the incidence of )alnutrition in the
se*enth grade students of ,- 7egeri 6ediri and -Ts 7 6ediri with
a *alue of p = 0.&.
ADVICE
a. Reacti*ate )onitoring of nutritional status of school
children to )onitor the growth and
de*elop)ent of nutritional status. This can be done through the
,chool 3ealth Enit rogra)
(E6,' that already eist.
b. 3old regular counseling about nutrition and health to
school students and also their parents.
c. 7eeds to be done further research on other factors affecting
the nutritional status of school
children.
