Antibiotic self-medication and home storage among university students in Vietnam: a cross-sectional study.
Article in BMJ open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectivesAntibiotic self-medication and home storage are two common behaviours that can result in inappropriate drug use. This study elucidated their prevalence and associated factors among university students in Vietnam.
designCross-sectional study.
settingVietnam.
participants2230 university students. PRIMARY AND SECONDARY OUTCOME MEASURES: Antibiotic storage was evaluated at the time of the survey, while self-medication was assessed for 1 year preceding this time. Associated factors were determined via multivariable logistic regression models.
resultsAmong 2230 participants, 418 (18.7%) reported self-medicating with antibiotics. The three main reasons for this behaviour included saving time (48.6%), mild diseases (45.0%) and the ease of purchasing antibiotics from community pharmacies (43.8%). Community pharmacies (88.3%) and home storage (36.4%) were the primary sources of antibiotics for self-treatment. Students mainly selected antibiotics based on community pharmacists' consultation (59.8%) and their knowledge/experience (37.8%). They commonly read the patient information leaflet (64.6%) and asked for the community pharmacist's advice to obtain information about antibiotic usage (52.9%). Besides, 296 students (13.3%) stored antibiotics at home. Over two-thirds had antibiotic leftovers from previous treatment and stored them for future use (69.3%), while 46.3% purchased antibiotics from community pharmacies without a prescription. Amoxicillin/clavulanic acid was the most commonly used antibiotic for self-medication (59.8%) and home storage (54.4%). Antibiotic self-medication was significantly associated with older age (adjusted odds ratio (aOR)=1.25; 95% CI 1.15 to 1.35), non-healthcare students (aOR=0.47; 95% CI 0.34 to 0.63), higher knowledge score (aOR=1.05; 95% CI 1.02 to 1.07) and storing antibiotics at home (aOR=7.12; 95% CI 5.34 to 9.51). Factors associated with home storage of antibiotics included non-healthcare students (aOR=2.77; 95% CI 2.01 to 3.83), region (north: aOR=6.50; 95% CI 3.49 to 13.54; south: aOR=5.92; 95% CI 3.06 to 12.65), having a family member working in the medical field (aOR=1.70; 95% CI 1.29 to 2.25), higher knowledge score (aOR=1.05; 95% CI 1.02 to 1.08) and antibiotic self-medication (aOR=7.58; 95% CI 5.69 to 10.14) (p values<0.001).
conclusionsThe prevalence of antibiotic self-medication and home storage among students was relatively low but still raises public health concerns. Some interventions, such as integrating targeted health education programmes into university curricula, orientation sessions, extracurricular activities and campus campaigns, may help effectively promote rational antibiotic use.
