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.

Parents' experiences of participating in the Healthy School Start Plus programme - a qualitative study.

BACKGROUND: The rise in overweight and obesity among children is a global problem and effective prevention interventions are urgently required. Parents play an important role in children's lifestyle behaviours and body weight development and therefore there is a great need to investigate how to involve parents effectively in health promotion and prevention programmes. The aim of the study was to describe parents' experiences of barriers and facilitators of participating in the Healthy School Start Plus (HSSP) intervention study. METHODS: HSSP is a parental support programme, conducted in Sweden, with the aim to promote a healthy diet, physical activity and preventing obesity in 5-7-year-old children starting school. In total 20 parents from 7 schools participated in semi-structured telephone-based interviews. The data was analysed using qualitative content analysis, with a deductive approach based on the Consolidated Framework for Implementation Research (CFIR). RESULTS: Parental experiences of barriers and facilitators informing the implementation of the HSSP intervention were identified within all five domains of the CFIR. Two additional constructs, not included in the CFIR were identified: Social factors and Cooperation. The findings of parental experiences of barriers and facilitators related to the importance of (1) adaptation of the intervention to fit the abilities of the parents with different social and cultural backgrounds; (2) the need for continuous delivery of information related to healthy behaviours; (3) the commitment and efforts of the deliverers of the intervention; (4) the need for repetition of information related to healthy behaviours given by the deliverers of the intervention; (5) encouragement and facilitation of the involvement of the family and key people around them through the intervention activities and by the deliverers of the intervention; (6) awareness of unexpected impacts and social and cultural conditions complicating the execution of the intervention and; (7) cooperation and a well-functioning interaction between parents and school staff. CONCLUSIONS: Barriers and facilitators indicated by the parents highlighted that interventions like the HSSP need to be adapted to fit the parents' abilities, with reminders, follow-ups and delivery of relevant information. Variations in social and cultural conditions need to be taken into consideration. The commitment of the school and the interaction between the school staff and the family as well as key people around them appears to be important. TRIAL REGISTRATION: The Healthy School Start Plus trial was retrospectively registered in the International Standard Randomised Controlled Trial Number Registry on January 4, 2018 and available online at ClinicalTrials.gov: No. NCT03390725.

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.

Leisure-time organised physical activity and dietary intake among Swedish adolescents.

This study aimed to investigate associations between participation in leisure-time organised physical activity (LTOPA) and dietary intake in a large representative sample of Swedish adolescents participating in the national dietary survey Riksmaten Adolescents 2016-2017. A sample of 2807 participants aged 11-12, 14-15 and 17-18 years were included. Information about LTOPA and dietary intake were collected through questionnaires and two 24-hour recalls on the web (RiksmatenFlex). For dietary intake, overall healthy eating index, intake of fruit, vegetables, candy, sugar-sweetened beverages, and the proportion of added sugar to total energy intake were analysed. Significance-testing for associations was performed with analysis of covariance. LTOPA was associated with lower sugar-sweetened beverages intake among adolescent boys (p < 0.001, ηp2 = 0.012) and girls (p = 0.007, ηp2 = 0.005), higher fruit intake among boys (p = 0.043, ηp2 = 0.003), and lower vegetable intake among girls (p < 0.001, ηp2 = 0.009). However, LTOPA was unrelated to the overall healthy eating index, candy intake, and the proportion of added sugar to total energy intake (p > 0.05). LTOPA was only associated with some healthy eating behaviours, and there is much room for improvement in the diets of Swedish adolescents.

Barriers and facilitators to successful implementation of sustainable school meals: a qualitative study of the OPTIMAT™-intervention.

BACKGROUND: There is an urgent need to align human diets with goals for environmental sustainability and population health. The OPTIMAT™-intervention study was developed to implement and evaluate a nutritionally adequate and climate-friendly 4-week lunch menu in Swedish primary schools. This study aimed to explore pupils' and kitchen staff's experiences of the intervention and to identify barriers and facilitators to successful implementation of sustainable school meals. METHODS: An inductive manifest qualitative method was used. Nine focus group discussions (FGDs) were conducted, six with pupils in grades 5 (ages 10-11) and 8 (ages 14-15) (n = 29) and three with kitchen staff (n = 13). Data were analyzed using qualitative content analysis. RESULTS: Five main categories and 11 subcategories at a manifest level emerged. The five main categories were: 1) Experiences with the new menu, unfolding variations in how the new menu was received and kitchen staff's experiences of working with it; 2) The meaning of diet sustainability, comprising pupils' and kitchen staff's perceptions about diet sustainability as a concept and part of their everyday lives; 3) Factors influencing plant-based food acceptance, covering aspects such as the influence of sensory factors, habits and peer pressure; 4) Opportunities to increase plant-based eating, including factors related to pupils' and kitchen staff's ideas for how to increase plant-based food acceptance; and 5) Need for a supportive environment to achieve dietary change, comprising pupils' and kitchen staff's thoughts on the importance of more knowledge, resources and involvement of stakeholders to eat more plant-based meals in schools. CONCLUSIONS: Successful implementation of sustainable school meals would require more knowledge among pupils and kitchen staff. Staff also need more training in cooking of sustainable meals. Barriers among pupils could be tackled by introducing new plant-based meals more gradually and by more carefully considering the seasoning, naming and aesthetics of dishes. An increased leadership support for change and involvement of stakeholders from multiple levels within society will be key in the transition to sustainable school meals at scale. TRIAL REGISTRATION: The trial registration for the OPTIMAT™-intervention may be found at clinicaltrials.gov ( NCT04168632 Fostering Healthy and Sustainable Diets Through School Meals (OPTIMAT)).

Brief parental self-efficacy scales for promoting healthy eating and physical activity in children: a validation study.

BACKGROUND: Brief scales to measure parental self-efficacy (PSE) in relation to children's obesogenic behaviours have not been developed and validated using more rigorous methodology such as invariance testing, limiting their generalisability to sub-groups. This study aimed to assess the construct validity and measurement invariance of brief PSE scales for children's intake of vegetables, soft drinks, and sweets, and physical activity. METHODS: Parents (n = 242) of five-to-seven-year-old children in disadvantaged and culturally diverse settings in Sweden responded to a questionnaire in Swedish with 12 items assessing PSE in relation to healthy and unhealthy behaviours. Construct validity was assessed with confirmatory factor analysis, invariance testing compared the scales by groups of parental sex, education, and child weight status. Criterion validity was evaluated using objective measures of children's physical activity and semi-objective measures of diet. RESULTS: Two-factor models showed moderate to excellent fit to the data. Invariance was supported across all groups for healthy behaviour scales. Unhealthy behaviour scales were invariant for all groups except parental education where partial metric invariance was supported. Scales were significantly correlated with physical activity and diet. CONCLUSION: This study provides preliminary evidence for the validity of brief PSE scales and invariance across groups suggesting their utility for research and clinical management of weight-related behaviours.

Potential health impact of increasing adoption of sustainable dietary practices in Sweden.

BACKGROUND: An urgent transition to more sustainable diets is necessary for the improvement of human and planetary health. One way to achieve this is for sustainable practices to become mainstream. We estimated the potential health impact of wider adoption of dietary practices deemed by consumers, researchers and stakeholders in Sweden to be niche, sustainable and with the potential to be scaled up. METHODS: A life table method was used to estimate the impact - changes in years of life lost (YLL) - over periods of 20 and 30 years in the Swedish population had the practices been adopted in 2010-11, when the last national adult dietary survey was conducted. The practices modelled were reducing red and processed meat (by 25, 50 and 100%), and assuming, for each stage, replacement by an equal weight of poultry/fish and vegetables +/- legumes; reducing milk intake (by 25, 50 and 100%); and reducing sugar-sweetened beverage intake (by 25, 50 and 100%). Using population data together with data on cause-specific mortality and relative risks for diet-disease outcomes, impacts were estimated for each scenario separately and in combination, for the outcomes ischaemic heart disease (IHD), ischaemic stroke, diabetes type 2 and colorectal cancer. RESULTS: For a "moderate" combination of scenarios (changes at the 50% level), reductions of 513,200 YLL (lower-upper uncertainty estimate 59,400-797,900) could have been achieved over 20 years and 1,148,500 YLL (135,900-1,786,600) over 30 years. The majority (over 90%) of YLLs prevented were related to IHD, and the majority were in men. The singular practice that had the most impact was reducing the intake of red and processed meat and replacing it with a mixture of vegetables and legumes. Reducing milk intake resulted in an increase in YLL, but this was compensated for by other scenarios. CONCLUSION: If these practices were more widely adopted, they would be expected to lead to improvements in public health in Sweden. Over the long term, this would translate to many premature deaths postponed or prevented from a number of chronic diseases, to the benefit of individuals, society, the climate and the economy.

IMplementation and evaluation of the school-based family support PRogram a Healthy School Start to promote child health and prevent OVErweight and obesity (IMPROVE) - study protocol for a cluster-randomized trial.

BACKGROUND: IMPROVE aims to conduct a hybrid type 3 evaluation design to test the effectiveness of bundled implementation strategies on intervention fidelity of the Healthy School Start (HSS) program, while simultaneously monitoring effects on health outcomes of children and parents. The HSS is a 4-component family support program for children starting school (5-7 years of age) promoting healthy dietary habits and physical activity in the home environment to prevent childhood obesity and parents' risk of developing type 2 diabetes. METHODS: IMPROVE is a cluster-randomized controlled trial with two arms to evaluate and compare the effects of two different bundles of implementation strategies on intervention fidelity expressed as adherence and responsiveness at 12 and 24 months (primary outcomes). Thirty schools in two municipalities will participate in the study reaching about 1400 families per school year. In stakeholder workshops, key implementation determinants were identified according to the domains of the Consolidated Framework for Implementation Research. Through a consensus process with stakeholders, two bundles of implementation strategies were tailored to address context-specific determinants. Schools randomly assigned to group 1 will receive bundle 1 (Basic) and group 2 will receive bundle 1 + 2 (Enhanced). Bundle 2 consists of external facilitation, fidelity monitoring and feedback strategies. Secondary outcomes will include change in acceptability, appropriateness, feasibility, and organisational readiness as perceived by school staff. In addition, child weight status and diet, and parents' feeding practices and risk of type 2 diabetes will be monitored. Linear and ordinal regression analysis will be used to test the effect on the primary and secondary outcomes, taking clustering and covariates into consideration where needed. Process evaluation will be conducted through key stakeholder interviews to investigate experiences of the program and perceptions on sustainability. DISCUSSION: This systematic approach to investigating the effectiveness of two different bundles of implementation strategies tailored to context-specific determinants on the fidelity of the HSS intervention will provide new insight into feasible implementation strategies and external support needed for the HSS to be effective and sustainable. Results will help inform how to bridge the gap between the research on school-based health programs and routine practice in schools.

Children's experiences of participating in a school-based health promotion parental support programme - a qualitative study.

BACKGROUND: Children's voices are seldom heard in process evaluations concerning health promotion programmes. A Healthy School Start Plus (HSSP) is a parental support programme, conducted in Sweden, with the aim of promoting healthy diet, physical activity and preventing obesity in preschool class children. The 6-month programme includes: (1) Health information to parents; (2) Motivational Interviewing with parents by school nurses; (3) Classroom activities and home assignments for children; (4) A self-test of type-2 diabetes risk for parents. We aimed to describe children's experiences of the third component regarding barriers and facilitators of participating in and learning from the classroom activities in the HSSP. METHODS: In total 36 children from 7 schools in Sweden, mean age 6 years, participated in 7 focus group discussions. Purposeful sampling with maximum variation was used to collect the data. The focus groups were audio-recorded, transcribed and analysed using qualitative content analysis. RESULTS: Four categories were identified; (1) Time available to work on intervention activities; (2) Others' interest; (3) Abilities and interests in intervention activities; and (4) Practicing the concept of health. CONCLUSIONS: The findings may improve the HSSP and other similar interventions that include classroom-based learning regarding health by highlighting the following points to consider: aiming for homework to be an integrated part of the school-setting to enhance parental involvement; using flexible material, tailored to the children's abilities and giving children adequate time to finish the intervention activities; and making teachers and parents aware of the importance of verbal and body language regarding intervention activities. TRIAL REGISTRATION: The Healthy School Start Plus trial was retrospectively registered in the International Standard Randomised Controlled Trial Number Registry on January 4, 2018 and available online at ClinicalTrials.gov: No. NCT03390725 .

"Everyone can take photos." Feasibility and relative validity of phone photography-based assessment of children's diets - a mixed methods study.

BACKGROUND: Dietary assessment methods that are user-friendly, simple, yet valid are of interest to both researchers and participants, particularly for use in disadvantaged settings, where language barriers and low levels of education are often present. We tested if parents taking photos of what children ate, using mobile phones, would be a feasible, acceptable method that could still provide information with adequate relative validity. METHODS: We used a mixed-methods design, with parents of 21 5- to 7-year-olds from disadvantaged areas in Sweden. Parents reported all dietary intake, during non-school hours, on three days (two weekdays) using a photo method (PM). The PM consisted of simple instructions and a fiduciary card, but no training, equipment or software. Text messages could be sent if necessary. As a reference method, parents completed three 24-h recalls (24HRs) with an interviewer each following day. The next week, parents completed a 9-item semi-FFQ regarding the preceding week. The outcomes were intakes (in dl) of 9 food groups, categorised as fruits and vegetables, energy-dense sweet/salty foods, and sweet drinks. Agreement with the reference 24HRs was assessed using correlations, median differences and Bland-Altman plots. Parents completed an open-ended questionnaire on barriers and facilitators. Data collectors provided complementary information. Qualitative data was analysed using qualitative manifest analysis. RESULTS: Nineteen parents (90%) provided complete data. The majority (n = 13) spoke Swedish as a second language, few (n = 4) were proficient. Compared to 24HRs, intakes measured by PM correlated well for all categories (Spearman's rho = 0.609-0.845). However, intakes were underreported, significantly so for fruits and vegetables; Bland-Altman plots indicated that the underestimation was fairly constant across intake levels. When the FFQ was compared to the 24HRs, parameters of agreement were generally inferior than for the PM. Parents found the PM a positive experience, primarily facilitated by its simplicity and familiarity. Barriers, mainly related to time and logistics, can inform further methodological refinements. CONCLUSIONS: The PM was an acceptable and feasible way to measure children's diet outside of school hours in this population of parents from disadvantaged areas. While the absolute validity should be evaluated further, this relatively simple method has potential for assessing intakes of well-defined foods at group level.

Sustainable and acceptable school meals through optimization analysis: an intervention study.

BACKGROUND: School meals hold considerable potential to shape children's diets and reduce food-related greenhouse gas emissions (GHGE)-in the short and long term. This study applied linear optimization to develop a GHGE-reduced, nutritionally adequate, and affordable school lunch menu. The effects on food waste, consumption and pupils' satisfaction with the meals were evaluated. METHODS: A pre-post design was employed to assess the effects of implementing an optimized lunch menu on daily food waste, consumption, and pupils' school meal satisfaction in three schools (grades 0-9) from one Swedish municipality. A food list containing amounts, prices, nutrient content, and GHGE-values of all foods used for a previously served (baseline) four-week lunch menu was created. Using linear programming, this food list was optimized for minimum deviation and constrained to ensure nutritional adequacy and a reduced climate impact. The optimized food list was developed into a new (intervention) four-week lunch menu by a professional meal planner, following the baseline menu as closely as possible. The baseline and intervention menus were served for four weeks, respectively, with a two week break in between. Prepared, wasted and leftover food were weighed daily by the school kitchen staff during both periods. Interrupted time series analysis assessed mean and slope differences in daily food waste and consumption between the two periods. School lunch satisfaction was assessed with an online questionnaire at baseline and during the intervention. RESULTS: Optimization resulted in a food list that was 40% lower in GHGE, met all nutrient recommendations for school meals, and cost 11% less compared to baseline. The intervention menu was served as planned, with only minor changes required (for practical reasons). Plate waste, serving waste, consumption and school lunch satisfaction did not differ significantly from baseline, in any of the schools. CONCLUSIONS: The findings demonstrate that school meals can successfully be improved regarding health and environmental sustainability using linear optimization, without negative effects on food waste, consumption or cost. This approach offers the necessary flexibility to tailor menus towards different priorities and could therefore be transferred to other types of meal services. TRIAL REGISTRATION: The trial is registered at clinicaltrials.gov (NCT04168632 Fostering Healthy and Sustainable Diets Through School Meals (OPTIMAT).

The importance of school lunches to the overall dietary intake of children in Sweden: a nationally representative study.

OBJECTIVE: School lunches have potential to foster healthy diets in all children, but data on their importance are relatively scarce. The current study aimed to describe the dietary intake from school lunches by sex and school grade, and to assess how the daily intake, school lunch intake and the daily intake provided by lunch differ by sex and parental education. DESIGN: Cross-sectional. All foods and drinks consumed for 1-3 weekdays were self-reported. Energy, absolute and energy-adjusted intakes of nutrients and food groups were calculated per weekday and per school lunch. Mixed-effects linear models assessed sociodemographic differences in dietary intakes. Nutrient and energy density at lunch and during the rest of the day were compared. SETTING: Seventy-nine Swedish primary schools. PARTICIPANTS: Pupils in grades 5 and 8 (N 2002), nationally representative. RESULTS: Lunch provided around half of daily vegetable intake and two-thirds of daily fish intake. Nutrient density was higher and energy density lower at lunch compared with the rest of the day (P < 0·001). Boys had greater energy-adjusted intakes of red/processed meat and lower intakes of vegetables and dietary fibre compared with girls (P < 0·001), overall and at lunch. Daily energy-adjusted intakes of most nutrients/food groups were lower for pupils of lower-educated parents compared with pupils of parents with higher education, but at lunch, only Fe and fibre intakes were significantly lower in this group. CONCLUSIONS: School lunches are making a positive contribution to the diets of Swedish children and may mitigate well-established sex differences and social inequalities in dietary intake.

Precrastination and the cognitive-load-reduction (CLEAR) hypothesis.

Precrastination is the tendency many individuals have to complete a task as soon as possible in order to get it out of the way [Rosenbaum, D. A., Gong, L., & Potts, C. A. (2014). Pre-crastination: Hastening subgoal completion at the expense of extra physical effort. Psychological Science, 25(7), 1487-1496. doi:10.1177/0956797614532657]. The current study (N = 48) examined whether precrastination is affected by a concurrent memory load as predicted by the cognitive-load-reduction (CLEAR) hypothesis. Participants completed a bucket-carrying task under different memory-load conditions. In addition, the amount of physical effort was manipulated by changing the distance people needed to walk while carrying the weighted buckets. The tendency to precrastinate by picking up a near bucket and carrying it further than necessary was affected by the memory load. People were more likely to precrastinate when doing so resulted in the more rapid renewal of cognitive resources and were less likely to precrastinate when this required that the memory load be held for a longer period of time. These data are consistent with the position that precrastination is linked with working memory resources and occurs in an attempt to clear items from a mental to-do list.

A Healthy School Start Plus for prevention of childhood overweight and obesity in disadvantaged areas through parental support in the school setting - study protocol for a parallel group cluster randomised trial.

BACKGROUND: Systematic reviews conclude that interventions to prevent overweight and obesity in children obtain stronger effects when parents are involved. Parenting practices and parent-child interactions shape children's health-related behaviours. The Healthy School Start Plus intervention aims to promote healthy dietary habits and physical activity and prevent obesity in children through parental support in disadvantaged areas with increased health needs, delivered by teachers and school nurses. This protocol describes the design, outcome and process evaluation of the study. METHODS: Effectiveness of the intervention is compared to standard care within school health services. The 6-month programme, based on Social Cognitive Theory, consists of four components: 1) Health information to parents regarding the child; 2) Motivational Interviewing with the parents by the school nurse concerning the child; 3) classroom activities for the children by teachers; and 4) a web-based self-test of type-2 diabetes risk by parents. Effects will be studied in a cluster randomised trial including 17 schools and 352 six-year old children. The primary outcome is dietary intake of indicator foods, and secondary outcomes are physical activity, sedentary behaviour and BMI. Outcomes will be measured at baseline, at 6 months directly after the intervention, and at follow-up 18 months post baseline. Statistical analysis will be by mixed-effect regression analysis according to intention to treat and per protocol. Mediation analysis will be performed with parental self-efficacy and parenting practices. Quantitative and qualitative methods will be used to study implementation in terms of dose, fidelity, feasibility and acceptability. The hypothesis is that the programme will be more effective than standard care and feasible to perform in the school context. DISCUSSION: The programme is in line with the cumulated evidence regarding the prevention of childhood obesity: That schools should be a focal point of prevention efforts, interventions should involve multiple components, and include the home environment. If effective, it will fill a knowledge gap concerning evidence-based health promotion practice within school health services to prevent obesity, and in the long term reduce social inequalities in health. TRIAL REGISTRATION: The trial was retrospectively registered on January 4, 2018 and available online at ClinicalTrials.gov : No. NCT03390725 .

Extending Awareness of Catholic Healthcare Ethics Among Junior Clinicians: A Qualitative Study.

As Catholic healthcare organizations form a substantive part of healthcare delivery in the USA and Australia, ethical standards for Catholic health care were developed to guide practice. This study examined junior staff's understanding of Catholic ethics. Using a qualitative descriptive design, we recruited 22 medical and nursing staff to interviews/focus groups. Though Catholic ethics seldom informed ethical approaches, the principles were acknowledged as being useful to support development of confident and respectful care approaches. Findings provide early insights into challenges faced in considering implementation of ethical codes across both secular and religious healthcare organizations, suggesting that a more creative and pastoral approach to dialoguing and implementing Catholic ethics is required.

Global region of birth is an independent risk factor for type 2 diabetes in Stockholm, Sweden.

Background: In Stockholm, type 2 diabetes (T2D) is a public health concern and much more prevalent in areas with a high proportion of foreign-born individuals. One in five individuals in Stockholm County are born outside of Sweden, and we therefore investigated if global region of birth was associated with diabetes risk, adjusting for established risk factors. Cross-sectional data from the population-based Stockholm Public Health Survey 2010 ( N = 69 115) was combined with registry-based information on country of birth grouped into eight global geographical regions. Cases of T2D were identified through self-reported physician-diagnosed diabetes and age at diagnosis. Region of birth was the independent risk factor and multivariable logistic regression analysis was performed adjusting for the risk factors age, sex, weight status, educational level, multiple dietary factors, tobacco, alcohol and physical activity. T2D prevalence was 5.1% in the sample. Relative to Swedish-born participants, higher odds ratio (OR) were found in those born in Asia [OR 3.2, 95% confidence interval (CI) 2.2-4.7], Sub-Saharan Africa (OR 2.5, 95% CI 1.5-4.1) and North Africa/the Middle East (OR 2.1, 95% CI 1.6-2.8), after adjustment for established risk factors. Participants from Eastern Europe and Latin America had an elevated risk but this did not remain after adjustment for other risk factors. Region of birth was found to be an independent risk factor for T2D for participants born in Asia, Africa and the Middle East. This increased risk should be taken into consideration when allocating resources for prevention, detection and care.

Objectively-measured sedentary time and cardiometabolic health in adults with severe obesity.

It is unknown whether sedentary behavior is independently associated with the cardiometabolic health of adults with severe obesity. Additionally, there is debate regarding how best to derive meaningful indices of sedentary time (ST) from activity monitor data. A convenience sample of adults with severe obesity (N=927; 79% female, median age 45y, median body mass index (BMI) 46kg/m(2)) completed a research assessment at one of ten US hospitals in 2006-2009 prior to bariatric surgery. Cardiometabolic health was assessed via physical measures, fasting blood samples and medication use. Indices of ST were derived from StepWatch™ activity monitor data with minimum bout durations of 1min, 10min and 30min. Cross-sectional associations were examined. Median (25th, 75th percentile) ST was 9.3h/d (8.1, 10.5) in ≥1min bouts, 6.5h/d (5.2, 8.0) in ≥10min bouts, or 3.2h/d (2.1, 4.5) in ≥30min bouts. Associations with ST were generally strongest with the ≥10min bout duration. Independent of moderate-to-vigorous intensity physical activity, BMI and other potential confounders, 1h/day ST in ≥10min bouts was associated with higher odds of diabetes by 15% (95%CI: 1.05-1.26), metabolic syndrome by 12% (95%CI: 1.01-1.24) and elevated blood pressure by 14% (95%CI: 1.02-1.26), and was associated with 1.4cm (95%CI: 0.9-1.9) larger waist circumference. Findings indicate the importance of considering ST as a distinct health risk among adults with severe obesity, and suggest a 10min minimum duration may be preferable to 1min or 30min for establishing ST from activity monitor data.

The intake of selected foods by six-year-old Swedish children differs according to parental education and migration status.

AIM: Little is known about how parental migration status may be associated with children's diets. We examined whether the intake of selected foods by six-year-old children differed according to their parents' migration status, taking education level into account. METHODS: This study used pooled baseline data from two clustered randomised controlled trials of A Healthy School Start, conducted in municipalities of low-to-medium socio-economic status in Stockholm County, Sweden. The children's intake of selected healthy and unhealthy foods was reported by parents using the Eating and Physical Activity Questionnaire, and the children's height and weight were measured. Parental education and country of birth were self-reported. RESULTS: Data were available for 520 children. Low parental education was associated with significantly higher intakes of fruit, higher intakes of several unhealthy foods and lower intakes of vegetables. Children of parents born outside the Nordic region had higher intakes of all unhealthy foods as well as fruit and vegetables, even when adjusted for education. A negative association between high education and overweight was only seen in children of Nordic-born parents. CONCLUSION: Parental migration status was a strong predictor of the intake of selected foods and was a stronger predictor than parental education.

Dietary fiber intake and its association with indicators of adiposity and serum biomarkers in European adolescents: the HELENA study.

PURPOSE: To evaluate total, energy-adjusted dietary fiber (DF), water-soluble fiber (WSF), and water-insoluble fiber (WIF) intakes in European adolescents and to investigate their association with indicators of adiposity and serum biomarkers. METHODS: This study, conducted from 2006 to 2007, included 1804 adolescents aged 12.5-17.5 years (47% males) from eight European cities completing two non-consecutive computerized 24-h dietary recalls. GLM multivariate analysis was used to investigate associations. RESULTS: Mean DF intake (20 g/day) of the sample met the European Food Safety Authority recommendation, but was below those of the World Health Organization and of the Institute of Medicine. Total DF, WSF and WIF intakes were higher in males (P < 0.001), but following energy-adjustments significantly higher intakes were observed among females (P < 0.001). Bread and cereals contributed most to total DF, WSF and WIF intakes, followed by potatoes and grains, energy-dense but low-nutritious foods, fruits and vegetables. Moreover, energy-adjusted WSF and WIF were positively associated with body fat percentage (BF%), waist to height ratio and low-density lipoprotein cholesterol, while energy-adjusted WSF was inversely associated with serum fasting glucose (ß = -0. 010, P = 0.020). CONCLUSION: Total DF intakes are rather low in European adolescents. An inverse association with serum fasting glucose might indicate a possible beneficial role of DF in preventing insulin resistance and its concomitant diseases, even though DF intakes were positively associated with adolescents' BF%. Therefore, further longitudinal studies should elaborate on these potential beneficial effects of DF intake in the prevention of obesity and related chronic diseases.

Improvements in school meal quality in Sweden after the introduction of new legislation-a 2-year follow-up.

BACKGROUND: Sweden provides a free school lunch to every child in the compulsory (9-year) school system. It consists of a hot meal, a salad buffet, bread and a beverage. The Education Act states it must be free of charge (since 1997) and 'nutritious' (since 2011). No standards/limits are specified but voluntary guidelines for serving of the school meal exist. We describe how school meal quality has changed since 2011. METHODS: A random sample of schools were contacted in spring 2011 and invited to use a novel web-based instrument to evaluate school meal quality. In spring 2013, the participating schools (N = 191) were encouraged to use it again and 97 did. The outcomes were measures of quality including food provision/choice, adherence to serving guidelines and, using validated food-based criteria, nutritional quality. RESULTS: No change was seen in the proportion offering alternative options daily, but a vegetarian option was significantly more widely available in 2013. Adherence to all but one of the studied serving guidelines improved, although this reached significance for only a small number. Adherence to two of the four nutrient criteria improved significantly. CONCLUSION: Two years after the introduction of new legislation, school meal quality in Sweden has improved modestly. The effect of the law itself is difficult to separate from other influences, including the effect of monitoring. Extended follow-up of schools will allow us to evaluate the longer-term changes and effects on health, learning and equality in health.
