Introduction:
Nicotine dependence among university students remains a public health concern, and psychological factors such as self-esteem may influence dependence severity. Evidence among respiratory therapy students in Saudi Arabia is limited. Hence, this study aimed to assess the relationship between nicotine dependence and self-esteem among respiratory therapy students in Saudi Arabia.
Methods:
This cross-sectional study was conducted between 13 March and 16 September 2025, and included 1041 respiratory therapy students. Inclusion criteria were enrollment from the second academic year through the internship year; first-year students were excluded. Data were collected via an anonymous online survey assessing smoking history, nicotine dependence using the Fagerström test for nicotine dependence (FTND), and self-esteem using the Rosenberg Self-Esteem Scale (RSES). Negative binomial regression was used to identify factors associated with nicotine dependence.
Results:
The median FTND score was 5 (IQR: 3-6). Smoking duration was significantly associated with higher nicotine dependence in a dose-response pattern. Compared with students who smoked for less than one year, those with 1-5 years (adjusted incidence rate ratio, IRR=1.10; 95% CI: 1.03-1.19; p=0.008), 6-10 years (IRR=1.15; 95% CI: 1.04-1.27; p=0.006), and >10 years of smoking (IRR = 1.31; 95% CI: 1.07-1.60; p=0.009) had higher dependence scores. Higher self-esteem was independently associated with lower nicotine dependence, with each one-point increase in RSES score linked to a 3% reduction in FTND score (IRR=0.97; 95% CI: 0.95-0.99; p=0.011). No demographic or academic variables were significantly associated with nicotine dependence.
Conclusions:
Nicotine dependence among respiratory therapy students is strongly related to smoking duration and self-esteem. Further longitudinal and interventional studies are needed to clarify the temporal relationship between selfe-steem and nicotine dependence and to determine whether psychosocial support could complement tobacco control efforts in university settings.

Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating sympathetic or...
