This study investigated the potential role of ambient air pollution in activating pulmonary TB (PTB) compared to extrapulmonary TB (EPTB). Materials and Methods: Data on TB cases were obtained from national surveillance data in Malaysia during 2013 and air pollution data were obtained from 52 air-monitoring stations around the country for the 3-year period of 2011-2013. Analyses were performed to estimate the odds of PTB vs. EPTB with changes in the 3-year (2011-2013) average Air Pollutant Index (API) and specific ambient air pollutants. Results: Results showed that the 95th-percentile of API levels during 2011-2013 was moderate and it was not associated with PTB. However, the odds of active PTB compared to EPTB was significantly elevated with the 95th-percentile levels for particulate matter with an aerodynamic diameter of 10 μm or less (aOR = 1.006, 95% CI: 1.002, 1.011), p-value Conclusions: These results provide suggestive evidence of the effects of ambient air pollution on development of active pulmonary TB compared to extrapulmonary TB. Additional research on the impacts of ambient air pollution on TB is warranted.展开更多

The study used data from the Malaysian Global School-based Health Survey which was conducted in 2012. Logistic regression analysis was used to establish associations. Of the 25,507 respondents, 34.9% (42.1% males and 27.8% females) reported having been in a serious injury. Compared to participants who were not bullied, those who reported being bullied were more likely to have sustained serious injury (aOR = 2.2;95% CI [1.95 - 2.48]). Adolescents who were involved in physical fighting were 57.5% (aOR = 2.75;95% CI [2.53 - 2.99]) and more likely to have sustained serious injury compared to those who were not involved in the fighting. Meanwhile, adolescents who used substances were 52.3% (aOR = 1.68 [1.52 - 1.85]) and more likely to have sustained serious injury compared to those who did not use substances. Serious injury is frequent among adolescents in Malaysia. Based on studies by Harel, suggestion where reduction of substance use and bullying may be assessed if they have an impact in reducing serious injury among adolescents. Furthermore, educational programmes that focus on the underlying causes and determinants of injury provide an effective and efficient method of injury prevention.展开更多
