The health care workers in public centers ware (51.1%) and (48.9%) of them works in private centers. One hundred and seventeen (49.4%) respondents had poor infection control knowledge, 113 (43.5%) had fair knowledge, and 17 (7.2%) had good knowledge. The knowledge was significantly associated with type of center (P < 0.018), such that the public center had the highest proportion with poor knowledge. And nurses and midwife having the highest proportion with fair knowledge of infection control. Eight (3.4%) respondents had a poor practice of universal precautions, 93 (39.2%) had fair practice, and 136 (57.4%) good practice. The practice was significantly associated with the profession, level of education and work experience (P < 0.001), (P < 0.006), (P < 0.001) respectively, and nurses and midwives as the profession with the highest proportion with good practice. We conclude that the practices and knowledge of universal precautions were low and that's need for intensive programmes to educate health care workers on various aspects of standard precautions and infection control programmes and policies.

Introduction: Many mental health disorders have onset during adolescence. To date, the data on the correlates of anxiety is still lacking. Therefore, this study is crucial to determine the factors associated with anxiety among school-going adolescents in Malaysia. Methodology: This study was based on 26,892 school-going adolescents from 212 selected schools in Malaysia. Anxiety was measured using Depression Anxiety and Stress Scale (DASS-21). Associations between anxiety, sociodemographic characteristics and variables of interest were examined using multivariable logistic regression. Results: Overall, 10,540 (39.7%) school-going adolescents had anxiety. Anxiety was positively associated with female (odds ratio, OR [95% confidence interval, CI] = 1.30 [1.19,1.42]) compared to male counterpart, feeling loneliness (1.78 [1.54,2.05]) compared to not lonely, unable to sleep due to worry of something (1.79 [1.56,2.05]) compared to able to sleep, being bullied (1.66 [1.48,1.87]) compared to not being bullied, physical abuse (1.33 [1.18,1.49]) compared to no physical abuse, verbal abuse (1.47 [1.35,1.59]) compared to no verbal abuse, current drinker (1.23 [1.06,1.43]) compared to not current drinker, current drug use (1.84 [1.43,2.35]) compared to not current drug use, ever had sex (1.17 [1.01,1.36]) compared to never had sex, physically inactive (1.16 [1.06,1.26]) compared to physically active and internet addiction (2.59 [2.37,2.83]) compared to no internet addiction. Chinese ethnic (0.68 [0.50,0.93]) compared to other ethnic, and Form 2 (0.78 [0.69,0.89]) and Form 3 (0.73 [0.65,0.82]) students compared to Form 1 students, were protective of anxiety. Conclusion Prevention and intervention programs for these “at-risk†adolescents should be planned holistically towards reducing the risk factors.

Introduction: Internet usage has changed the way adolescents socialize. This study aims to determine the determinants of internet addiction among school-going adolescents in Malaysia. Methods: This study was a cross-sectional study involving 27,455 school-going adolescents from 212 selected schools in Malaysia, as part of the 2017 National Health and Morbidity Survey that implemented a two-stage stratified cluster sampling design. Data collection via a self-administered questionnaire was conducted from March till May 2017. Results: Overall, 8,049 (29.0%) school-going adolescents had internet addiction. Internet addiction was positively associated with male (odds ratio, OR [95% confidence interval, CI] = 1.20 [1.08,1.34]) compared to female, Chinese ethnicity (1.67 [1.12,2.48]) compared to other ethnicity, feeling loneliness (1.37 [1.20,1.57]) compared to never feel lonely, unable to sleep due to worrying of something (1.40 [1.17,1.67]) compared to able to sleep, insufficient parental supervision (1.30 [1.14,1.48]) compared to sufficient parental supervision, depression (1.67 [1.48,1.89]) compared to no depression, anxiety (2.12 [1.95,2.30]) compared to no anxiety and stress (2.26 [1.96,2.61]) compared to no stress. The odds of having internet addiction increase from Form 2 (1.51 [1.28,1.78]), Form 3 (2.37 [2.01,2.80]), Form 4 (2.60 [1.76,3.85]) to Form 5 adolescents (2.96 [1.98,4.41]) compared to Form 1 adolescents.
