Universal healthy school start intervention reduced the body mass index of young children with obesity.

AIM: To evaluate the effect of a universal, school-based family support programme on body mass index (BMI) of children aged 5-7 years, using pooled data from three trials. METHODS: The programme has three to four components and is delivered during the first school year. It aims to promote healthy dietary and physical activity behaviours, and secondarily prevent unhealthy weight gain. Three cluster-randomised controlled trials were conducted between 2010 and 2018 in low and mixed socioeconomic status areas in Sweden. Weight and height were measured. Multiple mixed linear regression analysis was performed on the pooled data. RESULTS: In total, 961 children were included (50% girls, mean age 6.3 years). The post-intervention effect on BMI z-score in all children was small, but in those with obesity at baseline, we observed a significant, clinically relevant, decrease in BMI z-score (-0.21). This was most pronounced in children with a non-Nordic born parent (-0.24). Five to six months after the intervention, decreases were no longer statistically significant. CONCLUSION: The intervention resulted in changes in BMI comparable to obesity treatment programmes focusing on behaviour change. However, the effect attenuated with time suggesting the programme should be sustained and evaluated for a longer time.

The effectiveness of implementing the Guideline for the Prevention of Mental Ill-health Problems at the Workplace on health-outcomes, organizational and social risk factors: a cluster-randomized controlled trial in Swedish schools.

OBJECTIVES: This study aimed to compare the effectiveness of the multifaceted implementation strategy (multifaceted group) versus a discrete implementation strategy (discrete group) for implementing the Swedish Guideline for the Prevention of Mental Ill-health Problems at the Workplace on the primary intervention outcome - exhaustion - and secondary outcomes of stress, health, recovery, psychosocial safety climate, and social and organizational risk factors. Another aim was to examine whether the primary and secondary outcomes differed on the basis of guideline adherence levels, irrespective of the group. METHODS: A cluster-randomized waiting-list controlled trial with 6- and 12-months follow-up was conducted among 19 Swedish public schools. Primary and secondary outcomes as well as guideline adherence were assessed by self-reported questionnaire. Linear mixed modeling was used to compare differences in outcomes between the groups from baseline to 6 and 12 months, and in relation to different adherence levels. RESULTS: The trial comprised 698 employees (83.1%) participated. There were no differences between groups in the primary and secondary outcomes at 6 months, while at 12 months differences were observed for some outcomes to the advantage of the discrete group. Better guideline adherence was associated with improvements in exhaustion at 12 months and the secondary outcomes of psychosocial safety climate, work organization and job content, interpersonal relations and leadership, and recovery over 6 and 12 months. CONCLUSION: The multifaceted implementation strategy was no more effective than the discrete strategy in improving health outcomes or organizational and social work environment. However, higher adherence to the guideline was associated with larger improvements in health outcomes and organizational and social work environment, irrespective of the implementation strategy used.

Development of a tool to analyse what resources are needed to implement a midwife-led care framework- the MIDWIZE conceptual framework.

BACKGROUND: A midwife led care project targeting to decide what to do to achieve the SDG 2030 in maternal and child health, made a project team develop a tool to analyse what health care systems need, to adopt the MIDWIZE Conceptual Framework. The MIDWIZE Conceptual Framework wish to introduce the comprehensive midwifery-managed care provided women in Sweden to other countries, regions, and units where the framework is not fully applied. METHODS: In order to determine what resource needs would have to be met to improve midwife led care, a tool was developed using Delphi study technique. RESULTS: Using Delphi study technique together with on-site visits to two Sub-Saharan African countries, members of a project team went to Ethiopia and Uganda, where they visited governments, clinical or educational institutions and together with African leaders developed availability and efficiency of a tool to determine resource needs. CONCLUSION: If at some future time, a single country, region or unit, might want to use the tool for quality improvement purpose of midwife led care, then the tool might aid in taking the first step to determine what resources might be required and what changes might be recommended as concerns policy at the clinical or educational institution level that are part of already existing health care structures.

What works to improve school lunch nutritional quality - legislation or self-audit?

OBJECTIVE: Sweden updated its legislation on universal free school meals in 2011 and nutrition was explicitly mentioned. This study i) describes cross-sectional changes in school lunch nutritional quality during the following eight years, and ii) examines if repeated self-auditing, using a fully automated, online tool (School Food Sweden), based on the implementation strategy of audit and feedback, was associated with improvements. DESIGN: Both repeated cross-sectional and longitudinal design. Factors associated with meeting nutritional criteria were examined using variance weighted least squares regression and logistic regression. SETTING: Sweden. PARTICIPANTS: Primary schools who self-selected to audit meal quality between March 2012 and July 2019. RESULTS: Almost half of all (ca 4800) primary schools signed up to use the tool, and 1500 audited nutritional quality at least once. Repeated cross-sectional analyses showed the proportion meeting the nutritional criteria increased significantly between 2012/13 (11%) and 2018/19 (34%). Longitudinally, each additional audit completed increased the odds of meeting the nutritional criteria by 1.30 (CI 1.20-1.41), controlling for region and time elapsed since the legislative change. In 774 schools with repeat audits, both number of audits and frequency of accessing feedback predicted meeting the nutritional criteria (OR 2.02, CI 1.23-3.31), even after adjusting for time since the legislative change and days elapsed since previous audit. CONCLUSIONS: Both legislation and self-audit with automatic feedback appear effective in helping schools to improve school meal quality. Self-audit with feedback may be an effective complement to legislation, or a promising alternative in settings where regulation is not an option.

Promoting Evidence-Based Practice for Improved Occupational Safety and Health at Workplaces in Sweden. Report on a Practice-Based Research Network Approach.

Despite the rapid growth in research and R&D expenditures, the translation of research into practice is limited. One approach to increase the translation and utilization of research is practice based research networks. With the aim of strengthening evidence-based practice (EBP) within occupational health services in Sweden (OH-Services), a practice-based research network (PBRN-OSH) was developed. The PBRN-OSH includes researchers and representatives from end-users. This paper reports on the development, outputs and lessons learned in the PBRN-OSH. The PBRN-OSH resulted in several practice-based research projects as well as different measures to ensure EBP in OSH such as the governmentally sanctioned national guidelines for the OH-services. Moreover, results show that the competence in EBP increased among practitioners at the OH-services. Conducting research in a PBRN is more resource demanding; however, this does not imply that it is less cost effective. To succeed in increasing the utility of research findings via PBRN, resources must be invested into an infrastructure that supports collaboration in the PBRN, including costs for a variety of means of dissemination. Further, translation activities need to be included in academic career paths and reward systems if a major improvement in the impact and return of investments from research is to be expected.

Optimizing School Food Supply: Integrating Environmental, Health, Economic, and Cultural Dimensions of Diet Sustainability with Linear Programming.

There is great potential for reducing greenhouse gas emissions (GHGE) from public-sector meals. This paper aimed to develop a strategy for reducing GHGE in the Swedish school food supply while ensuring nutritional adequacy, affordability, and cultural acceptability. Amounts, prices and GHGE-values for all foods and drinks supplied to three schools over one year were gathered. The amounts were optimized by linear programming. Four nutritionally adequate models were developed: Model 1 minimized GHGE while constraining the relative deviation (RD) from the observed food supply, Model 2 minimized total RD while imposing stepwise GHGE reductions, Model 3 additionally constrained RD for individual foods to an upper and lower limit, and Model 4 further controlled how pair-wise ratios of 15 food groups could deviate. Models 1 and 2 reduced GHGE by up to 95% but omitted entire food categories or increased the supply of some individual foods by more than 800% and were deemed unfeasible. Model 3 reduced GHGE by up to 60%, excluded no foods, avoided high RDs of individual foods, but resulted in large changes in food-group ratios. Model 4 limited the changes in food-group ratios but resulted in a higher number of foods deviating from the observed supply and limited the potential of reducing GHGE in one school to 20%. Cost was reduced in almost all solutions. An omnivorous, nutritionally adequate, and affordable school food supply with considerably lower GHGE is achievable with moderate changes to the observed food supply; i.e., with Models 3 and 4. Trade-offs will always have to be made between achieving GHGE reductions and preserving similarity to the current supply.

Health and Work Environment among Female and Male Swedish Elementary School Teachers-A Cross-Sectional Study.

BACKGROUND AND OBJECTIVES: Changes in teachers' work situation in Sweden since the 1990s may have contributed to an increase in common mental disorders (CMDs) and burnout. However, there is a lack of research in this field. The aim was to describe how Swedish elementary school teachers experience their health, organizational and social work environment, and the psychosocial safety climate at the workplace, and especially differences and similarities between female and male teachers. MATERIALS AND METHODS: Data were collected with the COPSOQ, OLBI, UWES and PSC-12 from 478 elementary teachers, 81.0% of them women, from twenty schools. The response rate was 96.4%. RESULTS: Teachers reported relatively good general health but experienced high stress, high work pace and emotional demands, low influence at work and a poor psychosocial safety climate. These factors were especially prominent among female teachers. Both women and men experienced good development possibilities and high work engagement. CONCLUSIONS: The results of this study can help us to develop a more sustainable work environment for female and male teachers. A more sustainable work environment might attract more people to the profession and incentivize existing teachers to remain in the profession.

Correlates of Sedentary Behaviour in Adults with Intellectual Disabilities-A Systematic Review.

Individuals with intellectual disabilities (ID) are at high risk for high levels of sedentary behaviour. To inform the development of programmes to reduce sedentary behaviour, insight into the correlates is needed. Therefore, the aim of this study is to review the evidence on correlates of sedentary behaviour in adults with ID. We performed a systematic literature search in Ovid Medline, Ovid Embase, Web of Science and Google Scholar up to 19 January 2018, resulting in nine included studies that were published from 2011 to 2018. Correlates were categorized according to the ecological model. Studies predominantly focused on individual level correlates. Of those correlates studied in more than one study, having epilepsy was associated with less sedentary behaviour and inconsistent results were found for sex, genetic syndromes, weight status, physical health, mobility, level of ID, and mental health. Of the few interpersonal and environmental factors studied, only living arrangements were studied in more than one study, with inconsistent results. To date, we have limited and inconclusive evidence about correlates of sedentary behaviour in adults with ID. Only when future studies unravel correlates and determinants, across all domains of the ecological model, will the potential opportunities to improve health by reducing sedentary behaviour come within reach.

Psychometric Properties of a Scale to Assess Parental Self-Efficacy for Influencing Children's Dietary, Physical Activity, Sedentary, and Screen Time Behaviors in Disadvantaged Areas.

BACKGROUND: According to social cognitive theory, self-efficacy is central to behavior change. Consequently, parental self-efficacy (PSE) for influencing children's dietary, physical activity (PA), sedentary, and screen time behaviors is important for child obesity prevention. The aim of this study was to evaluate the psychometric properties of an instrument to measure PSE regarding these behaviors in disadvantaged areas. METHOD: Parents ( n = 229) of whom 47% had completed secondary school or less, and who participated in the Healthy School Start trial, responded to a 15-item PSE instrument. Children's diet and screen time were measured through parent reports. PA and sedentary behaviors were measured using accelerometers. Construct validity was assessed using exploratory factor analysis (EFA), criterion validity by correlations with child behaviors, and internal consistency by Cronbach's alpha. RESULTS: The EFA yielded three factors: (a) PSE for promoting PA; (b) PSE for limiting intake of unhealthy foods, unhealthy drinks, and screen time; and (c) PSE for promoting intake of fruits and vegetables, all with acceptable to good internal consistency (α = .77-.81). Significant correlations ( p < .01) were found between children's dietary ( rs = -.19 to -.29) and screen time ( r = -.29) behaviors and Factor 2, and dietary behaviors and Factor 3 ( rs = .20-.39) but not regarding PA and sedentary behaviors and Factor 1. CONCLUSION: The instrument demonstrated good construct validity and acceptable to good internal consistency regarding all but PA behaviors. It may be useful for assessing PSE in child obesity prevention interventions in disadvantaged settings after some refinement.

Definitions, measurement and prevalence of sedentary behaviour in adults with intellectual disabilities - A systematic review.

Supporting positive change in lifestyle behaviours is a priority in tackling the health inequalities experienced by adults with intellectual disabilities. In this systematic review, we examine the evidence on the definition, measurement and epidemiology of sedentary behaviour of adults with intellectual disabilities. A systematic literature search of PUBMED, EMBASE, MEDLINE and Google Scholar was performed to identify studies published from 1990 up to October 2015. Nineteen papers met the criteria for inclusion in the systematic review. Many researchers do not distinguish between insufficient physical activity and sedentary behaviour. None of the studies reported the reliability and validity of the methods used to measure sedentary behaviour. Sedentary time, assessed objectively, ranged from 522 to 643min/day: higher than in adults without intellectual disabilities. This first-ever review of sedentary behaviour and intellectual disabilities found that at present the evidence base is weak. Studies calibrating accelerometer data with criterion measures for sedentary behaviour are needed to determine specific cut-off points to measure sedentary behaviour in adults with intellectual disabilities. Researchers should also examine the reliability and validity of using proxy-report questionnaires to measure sedentary behaviour in this group. A better understanding of sedentary behaviour will inform the design of novel interventions to change lifestyle behaviours of adults with intellectual disabilities.

Factors influencing the implementation of a school-based parental support programme to promote health-related behaviours--interviews with teachers and parents.

BACKGROUND: The 'Healthy School Start' programme was developed to promote healthy dietary habits and physical activity, targeting parents of 6-year-old children in pre-school class. Knowledge of barriers and facilitators of implementation is crucial before introducing this kind of programme on a larger scale. The aim of this study was to explore the views of teachers and parents regarding factors influencing the implementation of a school-based parental support programme to promote physical activity and healthy diet. METHODS: An inductive qualitative method was used to explore the experiences and views of teachers and parents involved in the programme. A group discussion was held with three teachers, and semi-structured interviews were conducted with 14 parents. Data were analysed using qualitative content analysis. RESULTS: Clear communication on roles and responsibilities was identified as an overarching theme, emphasising the importance of clear information and well-functioning cooperation between project management, schools and parents when implementing the programme in a school setting. Five categories at a manifest level described aspects influencing the implementation: 1) 'The programme' underlining the importance of flexibility and feed-back; 2) 'the school' referring to management and work routines; 3) 'family conditions', implying various life situations; 4) 'group dynamics' dealing with attitudes among children and parents; and 5) 'the surrounding community' including accessibility and attitudes within society. CONCLUSIONS: When implementing a parental support programme in a school setting it is important to facilitate communication and clearly define the division of responsibilities between project management, schools and parents. This emphasises the need for managerial support, and a professional prevention support system.

Lower serum levels of beta-carotene in Lithuanian men are accompanied by higher urinary excretion of the oxidative DNA adduct, 8-hydroxydeoxyguanosine. The LiVicordia study.

OBJECTIVE: In 1995, middle-aged Lithuanian men had a four-fold higher risk than Swedish men of dying from coronary heart disease. The cross-sectional LiVicordia study had reported significantly lower levels of the lipid-soluble antioxidants lycopene, beta-carotene, and gamma-tocopherol among Lithuanian men than among Swedish men. We examined whether there were differences in urinary 8-hydroxydeoxyguanosine (8OHdG), a marker of oxidative stress, between these groups of men. METHODS: Using automated coupled column high-performance liquid chromatography with electrochemical detection, we examined 50-y-old men randomly sampled from Linköping, Sweden (n = 99) and Vilnius, Lithuania (n = 109) with regard to urinary concentrations of 8-OHdG. RESULTS: Levels of 8-OHdG were higher in the Lithuanian men than in the Swedish men (20.9 +/- 0.91 versus 14.9 +/- 0.75 nM/L, P < 0.001), and this difference was evident in smokers (P < 0.01) and non-smokers (P < 0.001). Serum levels of alpha- and beta-carotene were inversely correlated to urinary 8-OHdG levels (P < 0.05 in both cases). Habitual smoking and low levels of beta-carotene contributed significantly to higher oxidative DNA damage expressed as urinary 8-OHdG. CONCLUSIONS: These findings indicate that increased urinary 8-OHdG levels accompany lower serum levels of antioxidants in Lithuanian men. They supported previous suggestions that increased oxidative stress may be one factor behind the higher mortality in Lithuanian men.
