Anxiety and lifestyle behaviors among Lebanese university students during armed conflict: a cross-sectional study.
Article in BMC public health, 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
backgroundPolitical instability and armed conflict impose substantial psychological and behavioral challenges on young adults. University students may experience heightened anxiety alongside disruptions in eating behaviors (EB) and physical activity (PA) during periods of active conflict.
objectiveThis study aimed to examine the associations between anxiety, EB, PA and conflict-related strain among Lebanese university students exposed to war-induced stressors, and to identify the main factors associated with anxiety.
methodsA cross-sectional study was conducted among 401 students (mean age = 21 ± 2.2 years) during the most recent armed conflict in Lebanon (September- December 2024). Participants were recruited via snowball sampling from multiple Lebanese universities through an online survey diffused on social media platforms. Validated instruments were used, including the Generalized Anxiety Disorder-7 (GAD-7) scale, the short version of the International Physical Activity Questionnaire (IPAQ-SF), and an adapted EB questionnaire. Additional questions assessed sociodemographic, anthropometric measurements, conflict-related stressors, lifestyle changes and other relevant factors.
resultsClinically significant anxiety (GAD-7 ≥ 10) was observed in 43.6% of students and was more prevalent among females (p = 0.006). Anxiety was significantly associated with employment status (p = 0.014) and smoking status (p = 0.016), whereas EB, PA, and body mass index (BMI) showed no significant associations. In multivariable binary logistic regression, anxiety was associated with full-time employment (OR = 2.62; 95% CI: 1.20–5.73), direct exposure to bombings (OR = 2.77, 95% CI: 1.29–5.92), perceived academic functioning impairment (concentration or motivation) related to online classes (OR = 2.24, 95% CI: 1.00-4.99), stress-related changes in appetite (decreased appetite: OR = 3.63, 95% CI: 1.91–6.90; increased appetite: OR = 3.37, 95% CI: 1.88–6.04).
conclusionAnxiety was highly prevalent among Lebanese university students during active conflict and was primarily associated with war-related stressors, contextual academic and occupational pressures rather than with EB, PA, or BMI. These findings highlight the importance of context-sensitive mental health support within university communities during periods of socio-political instability and educational disruption.
