Prevalence of anemia and its association with body mass index among adolescent schoolgirls in Zarqa, Jordan.
Article in BMC nutrition, 2026. 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
backgroundAnemia is a critical public health issue that disproportionately affects adolescent girls due to their elevated physiological demands during rapid growth and the onset of menarche. This cross-sectional study investigated the prevalence of anemia and its association with body mass index (BMI) among adolescent schoolgirls in Zarqa, Jordan.
methodsA total of 420 participants aged 12–16 years were recruited through random sampling from six government schools between August 2024 and January 2025. Data collection included anthropometric measurements, complete blood count, dietary intake assessment, and sociodemographic characteristics.
resultsThe prevalence of anemia was 35%, with most cases classified as mild. Distribution of anemia across BMI categories revealed that 60.7% of anemic girls had a normal BMI, 22.3% were overweight, 14.2% obese, and only 1.4% severely thin. No significant association was found between BMI categories and anemia (p = 0.796), and correlation analysis confirmed a weak, non-significant relationship between BMI-for-age Z-score and hemoglobin levels (r ≈ 0.06, p = 0.55). Comparisons with regional and international studies highlight important contextual differences: in countries with higher undernutrition rates, low BMI has been a significant predictor of anemia, whereas in Jordan, dietary inadequacy, menstrual losses, and lifestyle factors appear to overshadow BMI as determinants.
conclusionsThe study underscores that the anemia–BMI relationship is not universal but rather shaped by the broader nutritional transition and socioeconomic context. These findings suggest that public health strategies in Jordan should prioritize improving diet quality, enhancing iron intake, and addressing adolescent health awareness over relying solely on anthropometric markers as predictors of anemia.
