The association between weight control behaviors and health literacy among adolescents: a cross-sectional study.

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
backgroundThe global rise in adolescent obesity underscores the need for effective weight control behaviors (WCBs) as an integral part of adolescents' lifestyles. Health literacy (HL), widely recognized as a key determinant of health outcomes, is an important factor in supporting informed health decisions. Given the potential influence of HL on health behaviors, this study aims to examine the association between WCBs and HL among adolescents in Tehran, Iran.
methodsA cross-sectional study was conducted from September to November 2021 across ten health service centers in southern Tehran. Adolescents were recruited via multistage random sampling. Data were collected using validated self-administered questionnaires assessing demographics, WCBs (healthy, unhealthy, and very unhealthy), and HL using the Health Literacy in School-Age Children scale. Descriptive statistics summarized participant characteristics and behaviors. A generalized linear model was used to adjust for age and BMI. In all tests, p < 0.05 was considered statistically significant.
resultsAmong the 240 adolescents included (mean age 14.25 ± 1.29 years; 48.8% female), 73.8% had a normal BMI, 7.1% were underweight, and 19.1% were overweight/obese. Nearly all (97.1%) reported at least one healthy WCB; 65.5% reported at least one unhealthy, and fewer than 5% reported very unhealthy behaviors. The mean HL score was 34.23 ± 4.48. Higher HL was associated with healthy WCBs, with odds increasing 3.4-fold from low to high HL (p < 0.001). No significant associations were detected between HL and unhealthy or very unhealthy WCBs.
conclusionsThese findings underscore the relevance of HL in promoting healthy WCBs among adolescents. The study highlights the potential value of developing strategies and programs to enhance HL, particularly for adolescents with higher BMI or those at risk of unhealthy behaviors, to support healthier lifestyle choices. Future longitudinal research is needed to further clarify the relationship between HL and WCBs over time.
