results of another study in Bone (2019) found that
menstrual disorders in adolescents ranged from
75.7% (Indriasari et al., 2019).
Data according to RISKESDAS (2013) in Sari
(2019) states that Indonesian women aged 10--59
years have menstrual cycle irregularities of 13.7%.
Data from West Java, according to RISKESDAS
2018, there are 72.15% of women who have
experienced menstruation with an average age of the
first menstruation of 12.70 years. According to the
results of Cabral's research (2019) found menstrual
disorders in adolescents around 100%. Another study
by Fahira (2021) stated that menstrual disorders in
adolescents are around 82.6%. Based on the results of
Manggul's research (2016) found that menstrual
disorders in adolescents were 66.2%.
Research conducted by Sitoayu (2017) stated that
there are several factors that cause menstrual
disorders, such as nutritional status, namely body
condition which is measured from weight weighing
and measuring respondents' height in accordance with
anthropometric guidelines using BMI / U and
processed using WHO Antroplus. The nutritional
status needed by each person is different, but lack or
even overnutrition will have a bad impact on health,
especially in young women because it can affect FSH
and LH hormones which result in menstrual disorders
(Felicia et al., 2015). Stress is a sense of interfering
both physical and psychic experienced by
respondents that causes pressure, stress can affect the
imbalance of FSH and LH hormones so as to increase
crh and GnRH hormones which can cause menstrual
cycles to be longer or shorter (AlJadidi et al., 2016).
Physical activity is an activity carried out by
respondents with a mild, moderate, severe level. The
high physical activity carried out can cause menstrual
disorders, but if the activity carried out tends to be
normal, it can reduce the risk of menstrual disorders
(Anindita et al., 2016). Carbohydrate intake was
respondents consuming foods containing fructose
within 24 hours before the time the study was
conducted. Juveniles need carbohydrates as a source
of energy during the luteal phase. Low carbohydrate
intake can result in depressed work of the hormone
estrogen so that the menstrual cycle is disturbed
(Rachmawati & Murbawani, 2015). Protein intake,
namely respondents consumed foods such as
processed milk, and so on within 24 hours before the
study was conducted. Protein functions as an energy
reserve for the body that functions to respond to
infertility and affects the follicular cycle
(Rachmawati & Murbawani, 2015). Fat intake was
that respondents consumed food sources of energy
within 24 hours before the time the study was
conducted. In reproduction, fats are beneficial in the
production of the hormone estrogen (Hanapi, 2021) .
According to the results of the study, there was a
relationship between, adequacy of carbohydrate
intake, adequacy of protein intake, adequacy of fat
intake, nutritional status, and stress with menstrual
disorders (Sitoayu et al., 2017). Subsequent studies
found that there were research results related to
physical activity and menstrual disorders
(Kusumawati et al., 2021).
A preliminary study that has been conducted at
SMAN 12 Depok City obtained from 30 female
students taken randomly by 30 people showed results
that as many as 70% of female students experienced
a faster menstrual cycle, 53.3% of female students
had menstruation twice in one month, 76.7% of
female students experienced pain during menstruation,
70% of female students experienced pain in the lower
abdomen alone. Based on this background, researchers
are interested in conducting a study with the title
"Factors related to menstrual disorders in students of
SMAN 12 Depok City in 2022”.
2 METHOD
This study used a Cross-Sectional design, where
observing an object in the form of risk factors and
their effects using one or more variables by collecting
data and to observe the relationship between variables
at the same time. The advantage of this design is that
its simple implementation does not require
complicated preparation, does not require much cost,
is effective, and the time it takes is not too long so that
the results are known faster (Siyoto, 2015).
This study is a quantitative study taken using
primary data using questionnaires containing
questions related to menstrual disorders, direct
measurements for nutritional status, stress, physical
activity, carbohydrate intake, protein intake, and fat
intake.
This study uses probability sampling technique,
namely with Simple Random Sampling, which is
sampling that is carried out randomly without paying
attention to the level in the population. The advantage
of the Simple Random Sampling technique is that it
does not require additional information other than the
population list, the formula used is easier, and more
efficient (Novita, 2018).
The sample in this study was 168 people. The
selection of samples is in accordance with the
inclusion criteria, namely active students of SMAN
12 Depok City, respondents have signed an approval
sheet, have menstruation.
