Abstract: Anemia is a condition of hemoglobin levels less than normal, which is prone to occur in adolescent girls due
to the menstrual cycle that occurs every month. In addition, dietary habits also affect hemoglobin levels of
adolescent girls. Dietary habits are also influenced by nutritional knowledge and social support from their
peers. This study aims to determine the association between nutritional knowledge and social support on the
incidence of anemia in adolescent girls. This study is an observational analytical study using the cross-
sectional method, with 12 respondents (total sampling) grade 7, 8, and 9 at Junior High School Alam Lampung.
Data collection of nutrition knowledge and social support was carried out by filling out questionnaires by
respondents, while blood capillaries sampling for hemoglobin measurement were done by researchers using
hemoglobin meters. The results of the study found that the average Hb respondents were 13.5mg / dl, there
were 2 respondents (16.7%) who had anemia, as many as 6 respondents had good nutritional knowledge
(50%), and as many as 7 people (58.3%) had good social support. There was no significant association
between the incidence of anemia and nutritional knowledge (p value: 0.12) or social support (p value: 0.79).
1 INTRODUCTION
Anemia is a condition where the levels of red blood
cells or hemoglobin in the body are below normal
levels according to age and physiological state of the
body. Adolescent girls have high risk of anemia
because of their rapid growth and development,
menstruation, poor dietary habits, peer pressure and
dieting. Based on the PRECEDE behavioral theory by
Lawrence Green, there are 3 factors that influence
health behavior, including predisposing, enabling
and reinforcing. Health behavior will affect the
incidence of anemia, predisposing factors that affect
the incidence of anemia one of them is iron
consumption (Junengsih dan Yuliasari, 2017),
knowledge (Yunita et al., 2020) and attitude (Listiana,
2016). Meanwhile the enabling factors that influence
the incidence of anemia is the availability of family
iron sources, and the strengthening factors are
maternal nutrition knowledge, maternal nutritional
attitudes, maternal nutritional behavior (Zuraida,
2020) as well as social support (Sri Raharjo dan
Indrayanti, 2021). In this study, researchers will look
for a relationship between adolescent girls'
knowledge and social support on the incidence of
anemia in junior high school Alam Lampung.
2 METHODS
This research is an observational analytical research
with cross sectional method. The population in this
study is 12 adolescent girls in grades VII, VIII and IX
(age 12-14 years old) at Junior High School Alam
Lampung, all population are taken as research sample
(total sampling method). Data was collected by filling
out questionnaires by respondents [18 points
nutritional knowledge questionnaire modified from
Zuraida (2020) and 7 points social support
questionnaire Duke-UNC FSSQ].

3 RESULTS AND DISCUSSION
3.1 Anemic Status of Adolescent Girls
The results of hemoglobin (Hb) levels of adolescent
girls of JHS Alam Lampung students were obtained
on average 13.5 mg / dl with the lowest level of 9.3
mg / dl and the highest 20.4 mg / dl/. Hb levels that
exceed 20mg / dl can be caused by several things such
as dehydration, chronic hypoxia, or other conditions
that produce excess erythropoietin, so a physical
examination and further support are needed to
determine the cause of the excess Hb levels. Based on
the examination from the 12 respondents, 10
adolescent girls who did not have anemia and 2
adolescent girls who had anemia (Table 1).
Table 1. Adolescent Girls' Anemia Status
Status n %
Non Anemic 10 83,3
Anemic 2 16,7
Total 12 100,0
The results of this examination showed good things,
because adolescent girls who did not have anemia
reached 83.3%. Normal haemoglobin levels indicate
a good level of health, because it is assumed that
oxygen transport and tissue oxygenation occur
optimally, so that energy production and other body
functions occur optimally (Ahmed et al., 2020).
Normal haemoglobin levels can be maintained by
ensuring a diet that contains balanced nutrition in
accordance with the portion of "isi piringku" for
adolescents (Kemenkes, 2023) shown in Figure 3.
Figure 3. Balanced Nutrition in Adolescents (Kemenkes,
2023)
The fulfilments of iron needs during adolescence not
only improves the reproductive health of adolescent
girls but will also have an impact until the adolescent
is an adult, especially during pregnancy and
childbirth (UNICEF, 2020). Adequate iron reserves
will minimize the occurrence of anemia in pregnant
women, so that the growth of the fetus conceived will
occur optimally and reduce the risk of low birth
weight and the incidence of stunting in the child itself
(Das et al., 2018). At the time of labor, the risk of
bleeding will be more minimal and postpartum
recovery will occur more optimally (Camaschella,
2019).
In addition to a diet that is in accordance with
balanced nutrition, haemoglobin levels can also be
maintained with the addition of iron supplements.
Based on information provided by JHS Alam
Lampung, students of junior and senior high school
Alam Lampung and Senior High School are routinely
given the iron supplements by the local Healthcare
Facility (Puskesmas Karang Anyar, Lampung
Selatan). However, no further attention has been paid
to the compliance of female students in consuming
the iron supplements itself.
3.2 Nutritional Knowledge of
Adolescent Girls
The results of research on nutritional knowledge of
adolescent girls obtained through filling out
questionnaires with 18 questions found that
adolescent girls who had good and less nutritional
knowledge each amounted to 6 people per category
(Table 2). The question items answered correctly in
the modified questionnaire from the Zuraida (2020)
Nutritional Knowledge, Social Support, and the Incidence of Anemia in Adolescent Girls in Junior High School Alam Lampung
235
questionnaire that contained questions regarding
nutrition slogans, balanced nutrition messages,
menus with balanced nutrition according to the
contents of my plate, animal protein sources, energy
adequacy for young women, menus with high iron
content, and foods that help or inhibit iron absorption.
Table 2. Results of Adolescent Girls’ Nutritional
Knowledge
Nutritional Knowledge n %
Great 6 50
Less 6 50
Total 12 100,0
These results show that adolescent girls who
have good nutrition knowledge have reached 50%,
this achievement level is quite good, considering the
characteristics of respondents, namely the age of
adolescent girls as respondents to this study ranged
from 12-14 years. Great nutritional knowledge will
support adolescents to have a more nutritious diet and
food selection, know the daily energy needs of
adolescents in order to balance between food intake
and physical activity needed so that ideal body weight
is maintained, manage reproductive health and
mental (emotional) which will have an impact on
good health behaviour (Hamulka et al., 2018).
However, nutrition knowledge alone will not
have a significant impact if it is not done in
conjunction with good eating practices (Chung &
Fong, 2018). Adolescent Girls with this age range still
depend on caregivers (mothers) in the process of
preparing daily meals, but it is hoped that with good
nutritional knowledge, adolescent Girls can
independently choose healthier foods, for example
when buying food in the school cafeteria.
3.3 Social Support of Adolescent Girls
Based on the results of research on adolescent girls'
social support, it was found that as many as 7
adolescent girls had great social support and 5
adolescent girls had less social support (Table 3). The
results of this examination showed good things,
because adolescent girls who had great social support
reached 58.3%.
Table 3. Results of Adolescent Girls’ Social Support

Social support can be interpreted as verbal or
actional assistance and attention. Some forms of
social support are emotional support (listening to
complaints, providing encouragement and moral
support), instrumental support (can be in the form of
services, financial assistance or transportation), or
information support (explanation of a matter or
giving advice). Social support can be provided by
family, peers, or teachers at school.
Adolescence is the age of transition from child to
adult, adolescents are easily influenced by something
or someone who is considered to play an important
role in adolescent profit. The role of support from
family, peers and teachers is very influential on the
behaviour of a teenager, including health behaviour.
Adolescents tend to worry about physical changes
along with the puberty phase they experience, with
sufficient support for adolescents will have better
health behaviours, such as peer support to take iron
supplementation tablets (Raharjo & Indrayanti, 2021).
3.4 The Relation of Nutritional
Knowledge, Social Support, and
Anemia Status of Adolescent Girls
Bivariate analysis in this study was conducted to see
the relationship between anemia status and nutritional
knowledge as well as anemia status and social support.
The statistical analysis test used is chi square and
obtained the results as listed in Table 4. The results of
bivariate analysis between anemia status and
nutritional knowledge showed that all adolescent girls
who had great knowledge did not have anemia or had
normal hemoglobin levels, while there were 4
adolescent girls who had less nutritional knowledge
and did not have anemia (66.7%), with a p value
obtained of 0.12, which means that nutritional
knowledge did not have a significant relationship
with anemia status.

These results show that although adolescent girls
have less nutritional knowledge, not necessarily these
adolescents have low haemoglobin levels, because
haemoglobin levels not only depend on good
nutritional knowledge, but are also influenced by
daily food intake containing balanced nutrition
(Kemenkes, 2014), iron supplements consumption
(Rahmiati, 2019), as well as the illness experienced
by a teenager (Camaschella, 2019).
The results of bivariate analysis between anemia
status and social support showed that of 7 adolescent
girls who had great social support, there were 6
(85.7%) adolescent girls who did not have anemia or
had normal haemoglobin levels and 1 person (14.3%)
who had anemia, while of 5 adolescent girls who had
less social support there were 4 people (80%) who did
not have anemia or had normal haemoglobin levels,
and 1 person (20%) who had anemia, with a p value
of 0.79 which means there was no significant
relationship between social support and anemia status.
4 CONCLUSION
Based on research that has been conducted on
adolescent girls of Junior High School Alam
Lampung, the following conclusions were obtained:
1. The results of anemia status found that as many
as 10 people (83.3%) are non anemic and 2
people (16.7%) are anemic.
2. The results of nutritional knowledge found that
as many as 6 people (50%) had great nutritional
knowledge and 6 people (50%) had less
nutritional knowledge.
3. The results of social support found that as many
as 7 people (58.3%) had great social support and
5 people (41.7%) had less social support.
4. There was no significant association between
anemia and nutritional knowledge with p value:
0.12.
5 There was no significant association between
the incidence of anemia and social support with
p value: 0.79.
