Gender-based analysis of adolescent nutrition: diet, lifestyle factors, and socioeconomic influences.
Article in BMC public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundAdolescent malnutrition is a major public health problem, yet sex-specific determinants such as lifestyle behaviors remain understudied. This study examined gender differences in dietary habits, lifestyle behaviors, and nutritional status among private high school students in Addis Ababa, Ethiopia.
methodsA cross-sectional study was conducted among 283 adolescents aged 14-19 years, randomly sampled from three private schools between October 2022 and June 2023. Data on socio-demographics, diet, and lifestyle were collected using a structured questionnaire. Anthropometric measurements classified nutritional status as stunted (height-for-age Z < - 2 SD), underweight (BMI-for-age Z < - 2 SD), overweight (BMI-for-age Z + 1 to + 2 SD), obese (BMI-for-age Z > + 2 SD), or well-nourished. Z-scores were computed using WHO AnthroPlus. Chi-square tests compared sex differences, and logistic regression identified predictors of nutritional status.
resultsBased on BMI-for-age, 50.5% of adolescents were well-nourished (- 2 SD to + 1 SD), 11.5% were underweight ( < - 2 SD), 26.2% were at risk of overweight (+ 1 to + 2 SD), and 5.7% were overweight ( > + 2 SD). Nearly 60% had poor dietary diversity, one-third skipped meals, and 49.5% had unhealthy weight. Boys were more physically active (≤ 1 h/day: 45.4% vs. 54.6%, p = 0.001) but more likely to skip meals (p = 0.04) and frequently consumed cakes and biscuits (p = 0.02). Girls reported higher fast-food intake (≥ 4 times/week) and longer screen time (> 2 h/day), though not significant. Among boys, younger age (14-16 years) increased odds of being well-nourished compared with older boys (AOR = 2.26, 95% CI: 1.12-4.60, p = 0.025). Among girls, frequent fast-food intake (AOR = 0.32, 95% CI: 0.10-1.00, p = 0.05) and screen time (AOR = 0.43, 95% CI: 0.20-0.94, p = 0.035) predicted suboptimal nutrition. Negative body image (AOR = 1.83, 95% CI: 1.13-2.98, p = 0.01) and screen time > 2 h/day (AOR = 0.60, 95% CI: 0.37-0.98, p = 0.04) were predictors for both sexes.
conclusionsAdolescent nutrition is shaped by shared and gender-specific factors. Body image and screen time influence both sexes, while younger age benefits boys and fast-food intake harms girls. Gender-responsive, school- and family-based interventions are needed.
