Exploring the influence of core-self evaluations, situational factors, and coping on nurse burnout: A cross-sectional survey study
<p>Stress has become an inherent aspect of the nursing profession. Chronically experienced work stress can lead to burnout. Although situational stressors show a significant influence on burnout, their power to predict the complete syndrome is rather limited. After all, stressors only exist “in the eye of the beholder”. This study aimed to explore how individual vulnerability factors such as core-self evaluations and coping, contribute to burnout in relation to situational stressors within a population of hospital nurses.</p> <p>Cross-sectional data was collected in 2014, using five validated self-report instruments: Dutch Core Self Evaluations Scale, Nursing Work Index Revised, Utrecht Coping List, Ruminative Response Scale, and Utrecht Burnout Scale. 219 of the 250 questionnaires were returned. This database is available here.</p> <p>Core-self evaluations, situational factors and coping each contributed significantly to the predictive capacity of the models of the separate burnout dimensions. Core-self evaluations was significantly related to emotional exhaustion. It was suggested that Core-self evaluations might be placed at the initiation of the loss cycle. However, further research is warranted.</p>
Stocks of paracetamol products stored in urban New Zealand households: A cross-sectional study
<p><b>Background</b></p> <p>Intentional self-harm is a common cause of hospital presentations in New Zealand and across the world, and self-poisoning is the most common method of self-harm. Paracetamol (acetaminophen) is frequently used in impulsive intentional overdoses, where ease of access may determine the choice of substance.</p> <p><b>Objective</b></p> <p>This cross-sectional study aimed to determine how much paracetamol is present and therefore accessible in urban New Zealand households, and sources from where it has been obtained. This information is not currently available through any other means, but could inform New Zealand drug policy on access to paracetamol.</p> <p><b>Methods</b></p> <p>Random cluster-sampling of households was performed in major urban areas of two cities in New Zealand, and the paracetamol-containing products, quantities, and sources were recorded. Population estimates of proportions of various types of paracetamol products were calculated.</p> <p><b>Results</b></p> <p>A total of 174 of the 201 study households (86.6%) had at least one paracetamol product. Study households had mostly prescription products (78.2% of total mass), and a median of 24.0 g paracetamol present per household (inter-quartile range 6.0-54.0 g). Prescribed paracetamol was the main source of large stock. Based on the study findings, 53% of New Zealand households had 30 g or more paracetamol present, and 36% had 30 g or more of prescribed paracetamol, specifically.</p> <p><b>Conclusions</b></p> <p>This study highlights the importance of assessing whether and how much paracetamol is truly needed when prescribing and dispensing it. Convenience of appropriate access to therapeutic paracetamol needs to be balanced with preventing unnecessary accumulation of paracetamol stocks in households and inappropriate access to it. Prescribers and pharmacists need to be aware of the risks of such accumulation and assess the therapeutic needs of their patients. Public initiatives should be rolled out at regular intervals to encourage people to return unused or expired medicines to pharmacies for safe disposal.</p>

Data from: Association between night-shift work, sleep quality, and health-related quality of life : a cross-sectional study among manufacturing workers in a middle-income setting
<p>Objectives: Night-shift work may adversely affect health. This study aimed to determine the impact of night-shift work on health-related quality of life (HRQoL), and assess whether sleep quality was a mediating factor.</p> <p>Design: Cross-sectional study.</p> <p>Setting: 11 manufacturing factories in Malaysia.</p> <p>Participants: 177 night-shift workers aged 40 to 65 years old were compared with 317 non-night-shift work.</p> <p>Primary and secondary outcomes: Participants completed a self-administered questionnaire on socio-demography and lifestyle factors, short Form-12v2 Health Survey (SF-12), and the Pittsburgh Sleep Quality Index (PSQI). Baron and Kenny's method, Sobel test and multiple mediation model with bootstrapping were used to determine whether PSQI score or its components mediated the association between night-shift work and HRQoL.</p> <p>Results: Night-shift work was associated with sleep impairment and HRQoL. Night-shift workers had significantly lower mean scores in all the eight SF-12 domains (p<0.001). Compared to non-night shift workers, night-shift workers were significantly more likely to report poorer sleep quality, longer sleep latency, shorter sleep duration, sleep disturbances, and daytime dysfunction (p<0.001). Mediation analyses showed that PSQI global score mediated the association between night-shift work and HRQoL. "Subjective sleep quality" (indirect effect=-0.24, standard error [SE]=0.14, bias corrected 95%Confidence Interval [BC 95%CI]: -0.58 to -0.01) and "sleep disturbances" (indirect effect=-0.79, SE=0.22, BC 95%CI: -1.30 to -0.42) were mediators for the association between night-shift work and physical wellbeing, whereas "sleep latency" (indirect effect=-0.51, SE=0.21, BC 95%CI: -1.02 to -0.16) and "daytime dysfunction" (indirect effect=-1.11, SE=0.32, BC 95%CI: -1.86 to -0.58) were mediators with respect to mental wellbeing.</p> <p>Conclusion: Sleep quality partially explains the association between night-shift work and poorer HRQoL. Organisations should treat the sleep quality of night-shift workers as a top priority area for action in order to improve their employees' overall wellbeing.</p>
Data for: Psychological distress, anxiety, suicidality, and wellbeing in New Zealand during the COVID-19 lockdown: a cross-sectional study
<p>Dataset for following paper.</p> <p>Introduction</p> <p>New Zealand's early response to the novel coronavirus pandemic included a strict lockdown which eliminated community transmission of COVID-19. However, this success was not without cost, both economic and social. In our study, we examined the psychological wellbeing of New Zealanders during the COVID-19 lockdown when restrictions reduced social contact, limited recreation opportunities, and resulted in job losses and financial insecurity.</p> <p>Methods</p> <p>We conducted an online panel survey of a demographically representative sample of 2010 adult New Zealanders. The survey contained three standardised measures – the Kessler Psychological Distress Scale (K10), the GAD-7, and the Well-Being Index (WHO-5) – as well as questions designed specifically to measure family violence, suicidal ideation, and alcohol consumption. It also included items assessing positive aspects of the lockdown.</p> <p>Results</p> <p>Thirty percent of respondents reported moderate to severe psychological distress (K10), 16% moderate to high levels of anxiety, and 39% low wellbeing; well above baseline measures. Poorer outcomes were seen among young people and those who had lost jobs or had less work, those with poor health status, and who had past diagnoses of mental illness. Suicidal ideation was reported by 6%, with 2% reporting making plans for suicide and 2% reporting suicide attempts. Suicidality was highest in those aged 18–34. Just under 10% of participants had directly experienced some form of family harm over the lockdown period. However, not all consequences of the lockdown were negative, with 64% reporting 'silver linings', which included enjoying working from home, spending more time with family, and a quieter, less polluted environment.</p> <p>Conclusions</p> <p>New Zealand's lockdown successfully eliminated COVID-19 from the community, but our results show this achievement brought a significant psychological toll. Although much of the debate about lockdown measures has focused on their economic effects, our findings emphasise the need to pay equal attention to their effects on psychological wellbeing.</p>
Cross-sectional study of Facebook addiction in a sample of Nepalese population
<p><strong>Background</strong>: Facebook addiction is said to occur when an individual spends an excessive amount of time on Facebook, disrupting one's daily activities and social life. The present study aimed to find out the level of Facebook addiction in the Nepalese context and briefly discuss the crimes associated with its unintended use.</p> <p><strong>Methods: </strong>A descriptive cross-sectional study was conducted in the Department of Forensic Medicine of Lumbini Medical College. The study instrument was the Bergen Facebook Addiction Scale typed into a Google Form and sent randomly to Facebook contacts of the authors. The responses were downloaded in a Microsoft Excel spreadsheet and analyzed using Statistical Package for Social Sciences version 16.</p> <p><strong>Results: </strong>The study consisted of 103 Nepalese participants, of which 54 (52.42%) were males and 49 females (47.58%). There were 11 participants (10.68%) who had more than one Facebook account. When different approaches were applied it was observed that 8.73% (n=9) to 39.80% (n=41) were addicted to Facebook.</p> <p><strong>Conclusion: </strong>When used properly Facebook has its own advantages. Excessive use is linked with health hazards including addiction and dependency. Students who engage more on Facebook will have less time studying leading to poor academic performance.People need to be made aware of the issues associated with the misuse of Facebook</p>

Data from: Does the performance of five back-associated exercises relate to the presence of low back pain? A cross-sectional observational investigation in regional Australian council workers
Objectives: investigate the relationships between the ability/inability to perform five physical test-exercises and the presence or absence of low back pain (LBP). Setting: regional Australian council training facility. Participants: consecutive participants recruited during 39 back education classes (8-26 participants per class) for workers in general office/administration, parks/gardens maintenance, roads maintenance, library, child-care and management. Total sample (n=539) was reduced through non-consent and insufficient demographic data to n=422. Age 38.6+/-15.3 years, range 18-64 years, 67.1% male. Methods: cross-sectional, exploratory, observational investigation. LBP presence was ascertained from a three-response option questionnaire: 0=none/rarely (NO) 1=sometimes (Some), 2=mostly/always (Most). Statistical correlation was performed with the number of the five test-exercises the individual successfully performed: 1) extension-in-lying, 3-seconds; 2) 'toilet-squat'; feet flat, feet touched, 3-seconds; 3) full-squat then stand-up, 5-times; 4) supine sit-up, knees flexed, 10-times; and 5) leg-extension, supine bilateral, 10-times. Interventions: nil. Results: for the group 'NO-Some', 94.3% completed 4-5 test-exercises, for 'With', 95.7% completed 0-1 test-exercises. The relationship between LBP presence and number of exercises performed was highly significant (Χ2(10)=300.61, p<0.001). Further, multinomial logistic regression predicting LBP (0=NO, 1=Some, 2=Most) from the number of exercises completed, substantially improved the model fit (initial-2LL=348.246, final-2LL=73.620, Χ2(2)=274.626, p<0.001). As the number of exercises performed increased, the odds of reporting 'Some-LBP' or 'Most-LBP' dropped substantially (odds ratios of 0.34 and 0.17, respectively). Conclusion: the ability to complete/not-complete five test-exercises correlated statistically and significantly with a higher LBP presence/absence in a general working population. Training individuals to complete such exercises could facilitate reductions in LBP incidence however, causality cannot be inferred. Randomized trials are recommended to establish the potential efficacy of exercise-based approaches, considering these five selected exercises, for predicting and managing LBP.
Seroprevalence of Entamoeba histolytica at a voluntary counselling and testing centre in Tokyo: a cross-sectional study
<p><strong>Background</strong> Amebiasis, which is caused by <em>Entamoeba histolytica</em>, is a re-emerging public health issue owing to sexually transmitted infection (STI) in Japan. However, epidemiological data are quite limited.<br> <strong>Methods</strong> To reveal the relative prevalence of sexually transmitted <em>E. histolytica</em> infection to other STIs, we conducted a cross-sectional study at a voluntary counselling and testing (VCT) centre in Tokyo. Seroprevalence of <em>E. histolytica</em> was assessed according to positivity with an enzyme-linked immunosorbent assay for <em>E. histolytica</em>-specific IgG in serum samples collected from anonymous VCT clients.<br> <strong>Results</strong> Among 2,083 samples, seropositive rate for <em>E. histolytica</em> was 2.64%, which was higher than that for HIV-1 (0.34%, p < 0.001) and comparable to that for syphilis (rapid plasma reagin (RPR) 2.11%, p = 0.31). Positivity for <em>Chlamydia trachomatis</em> in urine by transcription-mediated amplification (TMA) was 4.59%. Seropositivity for <em>E. histolytica</em> was high among RPR- or Treponema pallidum hemagglutination (TPHA)-positive individuals and it was not different between clients with and without other STIs. Both seropositivity of <em>E. histolytica</em> and RPR were high among male clients. The seropositive rate for anti-<em>E. histolytica</em> antibody was positively correlated with age. TMA positivity for urine <em>C. trachomatis</em> was high among female clients and negatively correlated with age. Regression analysis identified that male sex, older age, and TPHA-positive results are independent risk factors of <em>E. histolytica</em> seropositivity.<br> <strong>Conclusions</strong> Seroprevalence of <em>E. histolytica</em> was 7.9 times higher than that of HIV-1 at a VCT centre in Tokyo, with a tendency to be higher among people at risk for syphilis infection. There is a need for education and specific interventions against this parasite, as a potentially re-<br> 65 emerging pathogen.</p>
Data from: Age-appropriate vaccination coverage and its associated factors for pentavalent 1-3 and measles vaccine doses, in northeast Ethiopia: A community-based cross-sectional study
Background: In Ethiopia, there are no studies on age-appropriate vaccinations that children received at the recommended specific ages. Therefore, we assessed age appropriate vaccination coverage and its associated factors among children 12 to 23 months of age in Menz Lalo district, northeast Ethiopia. Methods: A community based cross sectional study was conducted in Menz Lalo district from March to April, 2018 among 417 mothers/caregivers with children 12 to 23 months of age using simple random sampling technique. Data were collected using pretested structured Amharic questionnaire. Age appropriate vaccination coverage was measured using World Health Organization vaccination schedule recommendation. Information about children vaccination status was collected from children vaccination cards. Data was entered into Epi-Info7 software and exported to SPSS-20 for analysis. Logistic regression analysis was carried out to identify factors associated with age inappropriate vaccinations. A p-value of < 0.05 was considered to sate statistically significant association. Results: Age appropriate vaccination coverage were 39.1% (95% CI: 34.1-43.6) for Pentavalent 1, 36.3% (95% CI: 30.5-40) for Pentavalent 2, 30.3% (95% CI: 23.5-32.4) for Pentavalent 3 and 26.4% (95% CI: 18-29.4) for measles vaccine doses. Age inappropriate Pentavalent 1-3 vaccinations was associated with being male child (AOR: 0.47, 95% CI: 0.29-0.74), absence of telephone (AOR: 2.2, 95% CI: 1.4-3.6), absence of usual caretaker (AOR: 2.6, 95% CI: 1.3-5.2), unplanned pregnancy (AOR: 1.9, 95% CI: 1.1-3.5), missing antenatal conference participation (AOR: 2.7, 95% CI: 1.3-5.7), first birth order (AOR: 0.34, 95% CI: 0.17-0.68) and insufficient knowledge (AOR: 2.7, 95% CI: 1.6-4.4). Conclusion: The proportion of age appropriate vaccinations coverage was low in the study area. Modifiable factors were associated with age inappropriate vaccinations. Vaccination interventions should consider identified modifiable factors to improve age appropriate vaccinations coverage.
