The effect of educational intervention based on the theory of planned behavior to prevent iron deficiency anemia in female high school students.
Trial report in BMC public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundIron deficiency anemia (IDA) is a prevalent health issue globally, with numerous research studies indicating that teenage girls in impoverished nations have a high incidence of this condition. Thus, the goal of this study is to figure out how education grounded in the theory of planned behavior (TPB) can prevent IDA in female high school students.
methodsIn Shiraz, Iran, 160 girls between the ages of 14 and 19 participated in this quasi-experimental study. Random sampling was used, and participants were randomly allocated to two experimental and control groups (each having 80 members). A questionnaire formed on the TPB was used as the data-collecting method, and both groups completed it pre- and four months post intervention. The educational program for the experimental group had six 50-60 min sessions that were conducted in schools using three different teaching styles (speaking, question and answer, and group discussion). After putting the data into the SPSS-24 statistical program, paired t, independent t, and chi-square tests were used to look at them.
resultsBefore the intervention, there was no significant difference between the two groups in terms of attitude (P = 0.213), subjective norms (P = 0.451), perceived behavioral control (P = 0.216), behavioral intention (P = 0.212), or behavior (P = 0.547). However, following the intervention, there was a significant difference between the two groups in terms of the mentioned constructs (P = 0.001).
conclusionIn the present study, education based on the TPB could successfully affect the nutritional behaviors for preventing IDA in girls aged 14-19 years. Probably, the results of this research can be used for students and their families and provide information for designing and planning interventions to prevent this disease among students at the disposal of subordinate organizations such as education, schools, universities of medical sciences, health centers, and nutrition clinics.
