Background Depression is common and tends to be recurrent. Alternative treatments are needed that non-stigmatising, accessible can prescribed by general medical practitioners. Aims To compare the effectiveness of three interventions for depression: physical exercise, internet-based cognitive–behavioural therapy (ICBT) treatment as usual (TAU). A secondary aim was assess changes in self-rated work capacity. Method total 946 patients diagnosed with mild moderate depression were recruited...
There is increasing evidence for the effectiveness of parental support programmes to promote healthy behaviours and prevent obesity in children, but only few studies have been conducted among groups with low socio-economic status. The aim this study was develop evaluate a programme dietary physical activity habits overweight six-year-old children disadvantaged areas. A cluster-randomised controlled trial carried out areas Stockholm. Participants were (n = 378) their parents. Thirty-one...
Evidence-based treatment of depression continues to grow, but successful and maintenance response remains limited.To compare the effectiveness exercise, internet-based cognitive-behavioural therapy (ICBT) usual care for depression.A multicentre, three-group parallel, randomised controlled trial was conducted with assessment at 3 months (post-treatment) 12 (primary end-point). Outcome assessors were masked group allocation. Computer-generated allocation performed externally in blocks 36 ratio...
Objective Academic performance in youth, measured by grade point average ( GPA ), predicts suicide attempt, but the mechanisms are not known. It has been suggested that general intelligence might underlie association. Methods We followed 26 315 Swedish girls and boys population‐representative cohorts, up to maximum 46 years of age, for first attempt hospital records. Associations between at age 16, IQ school 13 were investigated Cox regressions mediation analyses. Results There was a clear...
We assessed the effect of information sources on Ebola-specific knowledge and behavior during 2014-2015 Ebola virus disease outbreak in Sierra Leone. pooled data from 4 population-based knowledge, attitude, practice surveys (August, October, December 2014 July 2015), with a total 10,604 respondents. created composite variables for exposures (information sources: electronic, print, new media, government, community) outcomes (knowledge misconceptions, protective risk behavior) tested...
In order to develop health promotion initiatives it is important identify at what age gender and socioeconomic inequalities in health-related behaviours emerge. The aim of this longitudinal study was analyse how weight status differed by age-group, gender, family socio-economic over time three cohorts school children. All children grades 2, 4 7 a Swedish semi-urban municipality were invited participate (n = 1,359) which 813 (60%) consented. At baseline after 2 years questionnaire answered...
Introduction Infectious disease misinformation is widespread and poses challenges to control. There limited evidence on how effectively counter health in a community setting, particularly low-income regions, unsettled scientific debate about whether should be directly discussed debunked, or implicitly countered by providing scientifically correct information. Methods The Contagious Misinformation Trial developed tested interventions designed highly prevalent infectious Sierra Leone, namely...
Effects of obesity prevention interventions in early childhood are only meaningful if they sustained over time, but long-term follow-up studies rare. The school-based cluster-randomised Healthy School Start (HSS) trial aimed at child health promotion and through parental support was carried out 31 pre-school classes (378 families) disadvantaged areas Sweden during 2012-2013. Post-intervention results showed intervention effects on intake unhealthy foods drinks, lower BMI-sds children with...
Perceived susceptibility to a disease threat (risk perception) can influence protective behaviour. This study aims determine how exposure information sources, knowledge and behaviours potentially influenced risk perceptions during the 2014-2015 Ebola Virus Disease outbreak in Sierra Leone.The is based on three cross-sectional, national surveys (August 2014, n = 1413; October 2086; December 3540) that measured Ebola-related knowledge, attitudes, practices Leone. Data were pooled composite...
Recent studies of youth alcohol consumption indicate a collective downward drinking trend at all levels consumption, i.e. reductions occurring 'in concert'. We re-examine the collectivity theory by applying quantile regression methods to analysis and interpretation Swedish consumption. Changes in between 2000 2014 were assessed using school-based survey conducted Stockholm (n = 86,402). Participants aged 15–18 years. The rate change was examined regression, compared Ordinary Least Squares...
To quantify the potential impact of engaging religious leaders in promoting safe burial practices during 2014-2016 Ebola virus disease outbreak Sierra Leone.
Abstract In stochastic frontier analysis, the conventional estimation of unit inefficiency is based on mean/mode inefficiency, conditioned composite error. It known that conditional mean shrinks towards rather than inefficiency. this paper, we analytically prove mode cannot accurately estimate either. We propose regularized estimators restrict to satisfy some a priori assumptions, and derive closed form for three most commonly used densities. Extensive simulations show that, under common...
Abstract Interventions to improve health among adults with intellectual disabilities (ID) living in community residences are needed as unhealthy behaviors, obesity, and chronic diseases more common this group than the general population. This study evaluated effectiveness of a structural intervention, circle for paid carers aiming promotion work routines residents, explored barriers facilitators implementation process. A quasi‐experimental design was used. Eight municipalities 84 agreed...
Summary Background Despite numerous risk factors and serious consequences, little is known about metabolic dysfunction‐associated steatotic liver disease (MASLD) at population level in Africa. Aim The aim of the study was to estimate prevalence MASLD people living with without HIV Uganda. Methods We collected data from 37 communities South Central Uganda between May 2016 2018. estimated using fatty index advanced fibrosis dynamic aspartate‐to‐alanine aminotransferase ratio. additional on...
Abstract In this article, we modify a number of new biased estimators seemingly unrelated regression (SUR) parameters which are developed by Alkhamisi and Shukur (Citation2008), AS, when the explanatory variables affected multicollinearity. Nine ridge have been modified compared in terms trace mean squared error (TMSE) (PR) criterion. The results from extended study also with those founded AS. A simulation has conducted to compare performance parameters. showed that under certain conditions...
To evaluate changes in Ebola-related knowledge, attitudes and prevention practices during the Sierra Leone outbreak between 2014 2015.Four cluster surveys were conducted: two before peak (3499 participants) after (7104 participants). We assessed effect of temporal geographical factors on 16 attitude practice outcomes.Fourteen outcomes improved across all regions from to peak. The proportion respondents willing to: (i) welcome Ebola survivors back into community increased 60.0% 89.4%...
Abstract Background Clostridioides difficile infection (CDI) causes a major burden to individuals and society, yet the impact may vary depending on age, sex, underlying comorbidities where CDI was acquired (hospital or community). Methods This Swedish nationwide population-based cohort study (2006–2019) compared all 43,150 with their 355,172 matched controls (first year entire follow-up). Negative binomial regression models cumulated length of stay, number in-hospital admissions, outpatient...
New data on COVID-19 may influence the stringency of containment policies, but these potential effect are not understood. We aimed to understand associations new cases and deaths with policy globally regionally.
Abstract In this paper we introduce an interesting feature of the generalized least absolute deviations method for seemingly unrelated regression equations (SURE) models. Contrary to collapse leasts-quares parameter estimations SURE models ordinary least-squares individual when same regressors are common between all equations, proposed methodology not identical equations. This is important since contrary methods, one can take advantage efficiency gain due cross-equation correlations even if...
In this paper, the ridge estimation method is generalized to median regression. Though least absolute deviation (LAD) robust in presence of non-Gaussian or asymmetric error terms, it can still deteriorate into a severe multicollinearity problem when non-orthogonal explanatory variables are involved. The proposed increases efficiency LAD estimators by reducing variance inflation and giving more room for bias get smaller mean squared estimators. This paper includes an application new...
