Abstract

Background: Periodontal disease is a major global public health problem affecting billions of people worldwide and remains highly prevalent in low-resource settings, including Yemen. Disease progression is influenced by biological and behavioral factors, including age, gender, and region-specific habits, such as khat chewing, which is widely practiced in the Yemeni population. Objective: This study aimed to examine the relationship between khat chewing, age, gender, and periodontal status. Materials and Methods: This cross-sectional study included 570 Yemeni adult patients who attended outpatient dental clinics at the University of Science and Technology–Aden (UST), using data obtained from clinical records. Data were analyzed using descriptive statistics, chi-square tests, and multiple logistic regression. Adjusted odds ratios (AORs) with 95% confidence intervals (CIs) were calculated, and statistical significance was set at p< 0.05.Results: In the adjusted model, khat chewing was independently associated with periodontitis (AOR = 2.06; 95% CI: 1.36–3.15; p <  0.001). Participants aged >35 years had significantly higher odds of periodontitis (AOR = 3.93; 95% CI: 2.64–5.84; p< 0.001). No significant association was found between gender and periodontal status after adjustment. Conclusion: Khat chewing and older age were independent predictors of periodontitis, whereas gender showed no significant association.

Abstract

Background: Occupational safety in the land transport sector remains a critical concern as bus drivers are exposed to complex operational demands and potential safety risks. Purpose: This study aims to analyze the relationship between individual characteristics, individual factors, and safety culture with safety incidents among bus drivers at PT. X as well as to identify factors associated with safety incidents. Methods: A quantitative study with a cross-sectional design was conducted among 116 bus drivers at PT. X. Data were collected using a structured questionnaire consisting of measures for safety incidents, driving fatigue, sleep quality, risk perception, psychological well-being, and safety culture. The instruments included the Pittsburgh Sleep Quality Index (PSQI), Ryff’s Psychological Well-Being Scale, and previously validated questionnaires for other variables. Data were analyzed using Chi-Square tests and multiple logistic regression. Result : Among 116 respondents, 46 (39.7%) reported experiencing safety incidents, while 70 (60.3%) did not. Poor sleep quality was reported by 104 respondents (89.7%). Bivariate analysis showed a significant relationship between sleep quality (p=0.043; OR=3.474; 95% CI: 0.981–12.306), psychological well-being (p=0.004; OR=0.326; 95% CI: 0.150–0.705), and safety culture (p<0.001; OR=0.113; 95% CI: 0.048–0.266) with safety incidents. No significant relationship was found between age (p-value=0.220), years of service (p-value=0.768), driving duration (p-value=0.653), trip type (p-value=0.362), and driving fatigue (p-value=0.141) with safety incidents. Multivariate analysis showed that safety culture (p-value=0.000) was the variable most strongly associated with safety incidents (OR=0.113; CI 95% CI : 0.048–0.266). Conclusion: Safety culture showed the strongest association with safety incidents among the variables analyzed
