Brief summary

Introduction: The prevalence of anemia among adolescent girls in Indonesia is still quite high. According to the Indonesian Health Survey (IHS) in 2023, it was 18% and is still a national problem. Long-term supplementation of blood supplement tablets (TTD) as an effort made by the government to prevent/overcome anemia has caused side effects, namely dysbiosis by pathogenic bacteria. Giving cow's milk kefir containing various probiotics can overcome the side effects of supplementation, and its metabolites accelerate iron absorption so that iron status in the blood increases and ultimately restores anemia in adolescent girls. Method: It's research is an experimental study, with a Randomized Controlled Trial (RCT) design, pre-posttest design, involving research subjects of adolescent girls (15-18 years) with mild and moderate anemia, at SMKN 1, 2, and 3 Kasihan, Bantul Regency, Yogyakarta as many as 80 students. Subjects were divided into 2 groups, namely group 1 (treatment group), which was given 120 ml of cow's milk kefir every day and TTD 1 grain/week, and group 2 (control group), which was given 120 ml of cow's milk every day and TTD 1 grain/week. The duration of administration was 2 months. The study outcomes were Short Chain Fatty Acid (SCFA) levels in feces by Gas Chromatography-Mass Spectrometry (GC-MS) method, hemoglobin by Hematology Analyser method, and serum ferritin by Ferritin ELISA measured at the beginning and end of the study. Statistical analysis included univariate, bivariate, and multivariate analysis. Clinical analysis was also conducted to estimate the effect size of the treatment

Masking description

In addition to participants, service providers, and outcomes assessors, it is also disguised from statisticians or data processors so that the data obtained does not become biased

Design outcomes

Primary

MeasureTime frameDescription
Short Chain Fatty Acid2 months after interventionSCFA (acetate, propionate, and butyrate) levels in fresh feces of adolescent girls, using the GC-MS (Gas Chromatography-Mass Spectrometry) Method, were measured before (0 months) and after the intervention (2 months), using a ratio scale. The examination procedure included collecting feces in the field according to the procedure at https://drive.google.com/drive/folders/1uXklwFuC-1rnQ1Anim86b7-9pqLSheIz. Fresh feces samples were collected immediately, by storing them in a cool box (to maintain the quality of feces so that it remains stable during storage and transportation, and avoid the maturation process that can affect the results of lab tests, so that the results of the lab analysis carried out can be accurate and valid), and then immediately taken to the laboratory to quantify each of the short chain fatty acids (SCFA) in the sample.
hemoglobin2 months after interventionAdolescent girls' hemoglobin values in the blood taken from the median cubital vein, using the hematology analyzer method (unit g/dl), were measured before (0 months) and after the intervention (2 months), using a ratio scale.
Ferritin2 months after interventionFerritin content in the blood of adolescent girls taken from the median cubital vein, using the Ferritin ELISA method (unit µg/L), was measured before (0 months) and after the intervention (2 months), using a ratio scale

Secondary

MeasureTime frameDescription
Nutrient intake2 months after interventionThe amount of nutrients iron, folic acid, protein, vitamin C, zinc, energy and fat that enter the body of adolescent girls per day obtained from food and beverages, using the Food Record method carried out for 3 days, consisting of 2 times weekday and 1 time weekend, analyzed using the Nutrisurvey 2007 application, measured before (0 months) and after the intervention (2 months), using a ratio scale.
Diarrhea2 months after interventionComplaints of watery or loose bowel movements that occur more than 3 times a day were obtained through a questionnaire, using an ordinal scale, with the categories (1). No diarrhea if the frequency of bowel movements ranged from 1-2 times/day, with a solid consistency, and (2). Diarrhea, the frequency of bowel movements ranging ≥3 times/day, watery, thin consistency
Nutritional status of adolescent girls (body mass index / age)2 months after interventionThe Z-score or standard deviation (SD) value of adolescent girls after calculating the ratio of body weight in kilograms (kg) squared with height in meters (m) correlated with age, was analyzed using the WHO AnthroPlus application, measured before (0 months) and after the intervention (2 months), using a ratio scale. Weight values were obtained by weighing adolescent girls using digital scales with an accuracy of 0.1 kg. Height values were obtained by measuring the height of adolescent girls using a microtoise with an accuracy of 0.1 cm, and age was obtained by asking about the date/month/year of birth of adolescent girls. Using a questionnaire.
Menstrual cycle and duration of adolescent girls2 months after interventionThe physiological process experienced by adolescent girls, namely periodic bleeding from the uterus accompanied by the release of the endometrial wall every month, was obtained through a questionnaire, using an ordinal scale, with the categories (1). Normal if the menstrual cycle ranges from 21-35 days, and the length of menstruation is 3-7 days, and (2). Abnormal if the menstrual cycle ranges \<21 days and \>35 days, and the duration of menstruation is \<3 days and \>7 days
