Background: It is essential to decide on where to allocate available resources and identify priorities in noise control. Objectives: This study was performed to prioritize noise control solutions in various units of an oil refinery using the noise control priority index (NCPI). Methods: This cross-sectional study was conducted in an oil refinery in 2019. The standard of ISO 91612 was applied in the first stage to assess workplaces and determine the values of the noise pressure level (SPL). The activity of stations and the duration of workers’ presence in these stations were determined via interviews with the supervisors and senior personnel of each unit. The NCPI value in various units was determined using three variables, including the number of exposed people, exposure duration, and the weighting factor related to the sound pressure level (SPL). Finally, units were prioritized based on the final NCPI value. Results: Totally, 10 units were assessed based on the ISO9612 standard. The results revealed that 8.09% of the assessed stations were in the safe zone, 62.24% in the warning zone, and 29.66% in the hazard zone. The highest noise emission was related to the NTA unit (98 dB), and the lowest noise emission was observed in the spherical reservoir unit (84 dB). The NTA unit with 12 workers had the highest noise control priority index (1.25) among the units. Conclusions: The NCPI index makes it possible to appropriately prioritize noise control solutions in various industrial units and also implement technical and noise control plans in the oil and gas industries.

ABSTRACT Objective: To evaluate associations between snacking and energy, nutrients and food source, and to identify the contribution of snacking across age, sex, weight status and lifestyle behaviors among adolescents and young adults. Methods: A sub-sample was calculated from the population-based cross-sectional study 2015-Health Survey of São Paulo (ISA-Capital). The survey “ISA-Nutrição” used a sample of non-institutionalized individuals aged >15 years. For this study, only adolescents (12-18 years old; n=418) and young adults (19-29 years old; n=218) were included. Snacks were identified, and their contribution to energy, nutrients, and food sources were calculated. Descriptive statistics and logistic regressions were used. Results: Participants experienced an average of 2.9±0.6 snacking occasions per day. Young adults consumed more energy from morning and night snacks, and adolescents, from afternoon snacks. The top three food sources on snacking contributed to 30.5% of energy: cookies (11.8%), sugar sweetened beverages (9.4%), sweets and other desserts (9.3%). Although results were non-significant, being a female (Odds Ratio [OR] 0.93; 95% confidence interval [95%CI] 0.36-1.49), meeting the physical activity recommendations (OR 0.75; 95%CI 0.25-1.25), and scoring higher for the healthy eating index (OR 0.88; 95%C 0.24-1.52) were all factors related to increased intake of snacks. Alternatively, overweight individuals (OR -0.54; 95%CI -1.00 to -0.08) consumed less snacks. Conclusions: Improving the quality of snacks should be considered in behavior-change strategies.

PurposeThe aims of this study were to assess the food safety knowledge amongst domestic workers in the UAE and test the association between their socio-demographic characteristics and food safety knowledge.Design/methodology/approachA non-probabilistic sample of 231 domestic workers who help families in food preparation and/or cooking participated in this cross-sectional study. The participants completed a questionnaire composed of socio-demographic characteristics and four different aspects of food safety knowledge (personal hygiene, food poisoning, cross-contamination and temperature control).FindingsIt was observed that the domestic workers had inadequate knowledge about food safety with an overall food safety knowledge score of 32.9%. Total knowledge of “personal hygiene” and “cross-contamination” was relatively higher (46.2 and 43.9%, respectively) than that of “food poisoning” (18.1%) and “temperature control” (23.3%). A significant (P-value < 0.05) association was observed between overall food safety knowledge and marital status, age and education level, but not nationality of domestic workers (Asian or African).Originality/valueThe findings of this study are expected to encourage policy makers mandate food safety trainings for this segment of the population besides helping them in creating awareness and training programs regarding food safety.

Background Delayed tuberculosis diagnosis and treatment increase morbidity, mortality, expenditure, and transmission in the community. Early diagnosis and initiation of treatment are essential for effective TB control. Therefore, the main objective of this study was to assess the magnitude and factors associated with patient delay among tuberculosis patients in Gamo Zone, Southern Ethiopia. Methods A cross-sectional study was conducted in Gamo Zone, Southern Ethiopia from February to April 2019. Fifteen health facilities of the study area were selected randomly and 255 TB patients who were ≥18 years of age were included. Data were collected using a questionnaire through face-to-face interviews and analyzed using SPSS version 20.0. Patient delay was analyzed using the median as the cut-off value. Multivariable logistic regression analysis was fitted to identify factors associated with patient delay. A p-value of ≤ 0.05 with 95% CI was considered to declare a statistically significant association. Results The median (inter-quartile range) of the patient delay was 30 (15–60) days. About 56.9% of patients had prolonged patients’ delay. Patient whose first contact were informal provider (adjusted odds ratio [AOR]: 2.24; 95% confidence interval [CI] 1.29, 3.86), presenting with weight loss (AOR: 2.53; 95%CI: 1.35, 4.74) and fatigue (AOR: 2.38; 95%CI: 1.36, 4.17) and body mass index (BMI) categories of underweight (AOR: 1.74; 95%CI: 1.01, 3.00) were independently associated with increased odds of patient delay. However, having good knowledge about TB (AOR: 0.44; 95% CI: 0.26, 0.76) significantly reduce patients’ delay. Conclusion In this study, a significant proportion of patients experienced more than the acceptable level for the patient delay. Knowledge about TB, the first action to illness, presenting symptoms, and BMI status were identified factors associated with patient delay. Hence, raising public awareness, regular training, and re-training of private and public healthcare providers, involving informal providers, and maintenance of a high index of suspicion for tuberculosis in the vulnerable population could reduce long delays in the management of TB.

Background: During a pandemic, non-pharmaceutical interventions (NPIs) play an important role in protecting oneself from infection and preventing the spread of infection to others. There are large regional differences in COVID-19 infection rates in Japan. We hypothesized that the local infection incidence may affect adherence to individual NPIs. Methods: This cross-sectional study was conducted online among full-time workers in Japan in December 2020. Data from a total of 27,036 participants were analyzed. The questionnaire asked the respondents to identify their habits regarding seven well-known NPIs. Results: Compared to the region with the lowest infection rate, the odds ratios for the region with the highest infection rate were 1.24 (p<0.001) for wearing a mask in public, 1.08 (p=0.157) for washing hands after using the bathroom, 1.17 (p=0.031) for disinfecting hands with alcohol sanitizers when entering indoors, 1.54 (p<0.001) for gargling when returning home, 1.45 (p<0.001) for ventilating the room, 1.33 (p<0.001) for disinfecting or washing hands after touching frequently touched surfaces, and 1.32 (p<0.001) for carrying alcohol sanitizers when outdoors. Five of the seven NPIs showed statistically significant trends across regional infection levels, the two exceptions being wearing a mask in public and washing hands after using the bathroom. Multivariate adjustment did not change these trends. Conclusions: This study found that NPIs were more prevalent in regions with higher incidence rates of COVID-19 in Japanese workers. The findings suggest that the implementation of NPIs was influenced not only by personal attributes but also by contextual effects of the local infection level.

Perilaku seksual remaja semakin sering dijumpai dalam kehidupan sehari-hari. Perilaku ini dapat dipengaruhi oleh kurangnya peran orang tua dalam mengawasi remaja serta pengaruh teman sebaya. Tujuan penelitian ini adalah untuk melihat bagaimana hubungan peran orang tua dan teman sebaya terhadap perilaku seksual remaja. Penelitian ini bersifat kuantitatif dengan desain cross sectional study. Populasi dalam penelitian adalah semua siswa kelas X dan XI yang ada di salah satu SMA Kota Bandung yang berjumlah 580 orang. Sampel diambil menggunakan rumus estimasi absolute precision dan didapatkan jumlah sampel sebanyak 246 orang siswa. Data dikumpulkan menggunakan kuesioner perilaku seksual remaja, peran orang tua dan peran teman sebaya. Keseluruhan kuesioner telah dilakukan uji Reabilitas dan uji Validitas. Data dianalisis menggunakan chi Square. Hasil penelitian ini menunjukkan bahwa 49,6% siswa berperilaku seksual berisiko tinggi, 53,3% memiliki orang tua yang berperan tidak baik pada perilaku seksual remaja, 55,7 % memiliki teman sebaya yang berperan besar dalam perilaku seksual mereka. Ada hubungan yang bermakna antara peran orang tua dengan perilaku seksual remaja, akan tetapi tidak ada hubungan yang bermakna antara peran teman sebaya dengan perilaku seksual remaja. Sekolah disarankan dapat membentuk peer group dan pendekatan milenial untuk merubah perilaku remaja.

Occupational (professional) boredom results in low performance at work. It has been positively associated with high levels of anxiety and depression as well as premature death. However, occupational boredom has not been extensively studied among working nurses. This study aimed to investigate the relationship between emotional intelligence and occupational boredom in nurses working in both public (52.9%) and private (47.1%) health units in Greece. A cross-sectional study was conducted among a convenience sample of 189 nurses (84.7% females) with an average age of 40 years. Emotional intelligence was evaluated with the use of The Trait Emotional Intelligence Questionnaire-Short Form and Professional boredom was assessed with the use of the Boredom Proneness Scale. The majority of Nurses showed relatively high values of total Emotional Intelligence (EI), and marginally low values of overall Professional Boredom. A statistically significant negative correlation was found between the overall Professional Boredom of Nurses and the Well-being, Self-control, Emotionality and Sociability subscales of EI, as well as total EI (p < 0.001). Multiple linear regression analyses showed that the three dimensions of EI (Well-being, Self-Control and Emotionality) explained 39.0% of the variability of the total Professional Boredom of the working Nurses.
