The UP4FUN Intervention Effect on Breaking Up Sedentary Time in 10- to 12-Year-Old Belgian Children: The ENERGY-Project.
Pediatr Exerc Sci
PUBLISHED: 11-13-2014
Show Abstract
Hide Abstract
There are currently no studies available reporting intervention effects on breaking up children's sedentary time. This study examined the UP4FUN intervention effect on objectively measured number of breaks in sedentary time, number of sedentary bouts (?10 mins) and total and average amount of time spent in those sedentary bouts among 10- to 12- year-old Belgian children. The total sample included 354 children (mean age: 10.9±0.7 years; 59% girls) with valid ActiGraph accelerometer data at pre- and post-test. Only few and small intervention effects were found, namely on total time spent in sedentary bouts immediately after school hours (4-6PM; ß=-3.51mins) and on average time spent in sedentary bouts before school hours (6-8.30AM; ß=-4.83mins) and immediately after school hours in favour of children from intervention schools (ß=-2.71mins). Unexpectedly, girls from intervention schools decreased the number of breaks during school hours (8.30AM-4PM; ß=-23.45breaks) and increased the number of sedentary bouts on a weekend day (ß=+0.90bouts), whereas girls in control schools showed an increase in number of breaks and a decrease in number of bouts. In conclusion, UP4FUN did not have a consistent or substantial effect on breaking up children's sedentary time and these data suggest that more intensive and longer lasting interventions are needed.

Hide Abstract
The school is an important setting for promoting healthy eating especially at the transition from childhood to adolescence. This study contributes to the literature by describing practices within physical, political and sociocultural aspects of the school nutrition environment in seven countries across Europe based on questionnaires to the school management, and exploring their associations with soft drink consumption reported on questionnaires by 10-12 year olds. Several of the commonly self-reported practices could be supportive of a healthy diet (time to eat, access to water, restriction on marketing), but some practices were underutilized (i.e. discussion with stakeholders, healthy foods at events). Only a few associations of practices with the pupils? soft drink consumption were found.

Screen-related behaviours are highly prevalent in schoolchildren. Considering the adverse health effects and the relation of obesity and screen time in childhood, efforts to affect screen use in children are warranted. Parents have been identified as an important influence on children's screen time and therefore should be involved in prevention programmes. The aim was to examine the mediating role of family-related factors on the effects of the school-based family-focused UP4FUN intervention aimed at screen time in 10- to 12-year-old European children (n child-parent dyads = 1940).

Hide Abstract
The aim of this study was to systematically review available evidence on the association between health-related quality of life (HRQoL) and survival in patients with head and neck cancer (HNC), adjusted for important clinical, demographic and lifestyle-related factors. A systematic literature search in four electronic bibliographic databases was conducted in January 2014. We included studies that provided data on HRQoL, survival, and the association between HRQoL and survival among HNC patients. Two researchers independently rated the quality of the included studies. A best evidence synthesis was applied to draw conclusions. Nineteen studies were included, of which twelve focused on all subscales of a HRQoL questionnaire and seven focused on selected subscales. The mean (SD) quality score was 72 (17)% and 11 (58)% studies were of high quality. According to the best evidence synthesis, we found strong evidence for a positive association between pre-treatment physical functioning and survival and between change in global QoL from pre-treatment to 6months after treatment and survival. Due to inconsistent findings, we found insufficient evidence for an association with survival of other HRQoL domains, including role, emotional, cognitive and social functioning, mental health and well-being. Future high quality studies with a longitudinal design are needed to examine the complex association between HRQoL and survival.

The family, and parents in particular, are considered the most important influencers regarding children's energy-balance related behaviours (EBRBs). When children become older and gain more behavioural autonomy regarding different behaviours, the parental influences may become less important and peer influences may gain importance. Therefore the current study aims to investigate simultaneous and interactive associations of family rules, parent and friend norms and modelling with soft drink intake, TV viewing, daily breakfast consumption and sport participation among schoolchildren across Europe.

Hide Abstract
For an exercise intervention to be successful, it is important that cancer survivors adhere to the prescribed program. To be able to improve adherence and to preserve achieved beneficial effects, insights into the relevant and modifiable determinants is important. Therefore, we aimed to systematically review determinants of exercise adherence and maintenance in cancer survivors using a socio-ecological approach.Studies were identified in PubMed, Embase, PsycINFO and SPORTDiscus up to July 2013. We included full-text articles that: 1) were conducted among adult cancer survivors; 2) quantitatively assessed factors associated with intervention adherence and maintenance, and 3) were published in English. The methodological quality of the selected studies was examined. A best evidence synthesis was applied. Eighteen studies were included. Median methodological quality was 53% and ranged from 21-78% of maximum score. Twelve studies focused on determinants of exercise adherence and evaluated 71 potential determinants: 29 demographic and clinical, 27 psychological, ten physical, four social factors, and one environmental factor. Six studies focused on determinants of exercise maintenance after completion of an intervention, and investigated 63 factors: 22 demographic and clinical, 28 psychosocial, nine physical, three social and one environmental factor. We found moderate evidence for a positive association between exercise history and exercise adherence. Inconsistent findings were found for age, gender and education as well as for psychological factors such as stage of change, perceived behavioral control, self-efficacy, extraversion, attitude, intention, fatigue, and quality of life, and physical factors including cardiovascular fitness, body mass index, and baseline physical activity.Exercise history is positively associated with exercise adherence. Future trials should further study the influence of social and environmental determinants on exercise adherence and maintenance in addition to demographic, psychological and physical determinants.

Hide Abstract
This study assessed to what extent genetic and environmental factors contributed to individual differences in adolescent sleep duration, and whether genetic and environmental contributions to sleep duration changed throughout adolescence. A twin-family design was used to gain insight into the genetic and environmental contributions to variation in sleep duration. The study sample consisted of 6,319 adolescent twins (44% males) and 1,359 non-twin siblings (44% males) in the age range of 12 to 20 years (mean age = 16.85, SD = 1.40). The participants self-reported usual sleep duration, which was categorized as less than 8 hours per night, 8-9 hours per night, and more than 9 hours per night. Results showed that the prevalence of shorter than optimum sleep duration, that is, less than 8 hours per night, was high, with the highest prevalence rates in later adolescence. The contribution of genetic and environmental factors to individual differences in sleep duration was dependent on age. Variation in sleep duration at the age of 12 years was accounted for by genetic (boys: 34%, girls: 36%), shared environmental (boys: 28%, girls: 45%), and non-shared environmental factors (boys: 38%, girls: 19%). At the age of 20 years, the role of genetic (boys: 47%, girls: 33%) and non-shared environmental factors (boys: 53%, girls: 67%) was more pronounced. It can be concluded from the results that individual differences in sleep duration were accounted for by genetic and non-shared environmental factors throughout adolescence, whereas shared environmental factors account for a substantial part of variation during early adolescence only.

Hide Abstract
Associations between parental perceived home and neighbourhood environments and childrens physical activity (PA), and sedentary time (ST) and screen time and moderating effects according to urban/rural location were examined. Data were collected (2007-2008) from a cohort of women (aged 18-45 years) and their children (5-12 years) participating in the Resilience for Eating and Activity Despite Inequality (READI) study. A total of 613 children (47% boys; mean age 9.4±2.2 years) and their mothers were included in the study. Urban children had higher screen time than rural children. Mothers in rural areas reported greater access to physical activity equipment in the home, higher levels of descriptive norms for physical activity, greater knowledge of the neighbourhood, a stronger social network, and higher personal safety than urban mothers. There were five significant interactions between the home and neighbourhood environment and PA/ST according to urban/rural location. Among urban children, the importance of doing PA together as a family was positively associated with ST. Interventions targeting PA and ST may need to target different factors according to urban/rural location.

Hide Abstract
Effective interventions to improve quality of life of cancer survivors are essential. Numerous randomized controlled trials have evaluated the effects of physical activity or psychosocial interventions on health-related quality of life of cancer survivors, with generally small sample sizes and modest effects. Better targeted interventions may result in larger effects. To realize such targeted interventions, we must determine which interventions that are presently available work for which patients, and what the underlying mechanisms are (that is, the moderators and mediators of physical activity and psychosocial interventions). Individual patient data meta-analysis has been described as the gold standard of systematic review methodology. Instead of extracting aggregate data from study reports or from authors, the original research data are sought directly from the investigators. Individual patient data meta-analyses allow for adequate statistical analysis of intervention effects and moderators of such effects.Here, we report the rationale and design of the Predicting OptimaL cAncer RehabIlitation and Supportive care (POLARIS) Consortium. The primary aim of POLARIS is 1) to conduct meta-analyses based on individual patient data to evaluate the effect of physical activity and psychosocial interventions on the health-related quality of life of cancer survivors; 2) to identify important demographic, clinical, personal, or intervention-related moderators of the effect; and 3) to build and validate clinical prediction models identifying the most relevant predictors of intervention success.

Hide Abstract
BACKGROUND: To assess the association of eating meals, and never watching TV while eating meals, with weight status among children, ages 10--12 years across Europe. METHODS: 7915 children (mean age: 11.5 years) in eight European countries (Belgium, Greece, Hungary, the Netherlands, Norway, Slovenia, Spain and Switzerland) completed a questionnaire at school. Data on meals eaten the day before questionnaire administration and the frequency of eating meals while watching TV were collected. Height and weight of the children were objectively assessed. Multinomial and binary regression analyses were conducted to test associations of eating meals (adjusted for gender and ethnicity) and never watching TV while eating meals (adjusted for gender, ethnicity and total TV time) with overweight/obesity, and to test for country- and socio-demographic differences. RESULTS: The proportions of children reporting eating breakfast, lunch and dinner were 85%, 96%, and 93% respectively, and 55%, 46% and 32% reported to never watch TV at breakfast, lunch and dinner respectively. The children who ate breakfast (OR = 0.6 (95% CI 0.5-0.7)) and dinner (OR = 0.4 (95% CI 0.3-0.5)), had lower odds of being overweight compared to those who did not. The children who never watched TV at lunch (OR = 0.7 (95% CI 0.7-0.8)) and dinner (OR = 0.8 (95% CI 0.7-0.9)) had lower odds of being overweight compared to those who watched TV at the respective meals. CONCLUSIONS: The odds of being overweight was lower for children who ate breakfast and dinner compared to those who did not eat the respective meals. The odds of being overweight was lower for children who reported to never watch TV at lunch and dinner compared to those who did. A focus towards meal frequency and watching TV during meals in longitudinal and interventions studies in prevention of overweight and obesity, may contribute to a better understanding of causality.

OBJECTIVES: This study aims to describe the time devoted to sedentary and physical activities at school in five European countries and to examine differences according to country, sex, ethnicity, parental education and weight status. DESIGN: cross-European cross-sectional survey. METHODS: Primary schoolchildren (n=1025) aged 10-12 years in Belgium, Greece, Hungary, the Netherlands, and Switzerland wore accelerometers for at least six consecutive days. Only weekdays were used for this study to calculate the percentages of school-time spent in sedentary activities and moderate to vigorous intensity activity. Trained research assistants measured height and weight. Sex and date of birth were self-reported by the child and parental education and ethnicity were parent-reported. RESULTS: European schoolchildren spent on average 65% of their time at school in sedentary activities and 5% on moderate to vigorous intensity activities, with small differences between countries. Girls spent a significant larger amount of school-time in sedentary activities (67%) than boys (63%; p<0.0001), and spent less time in moderate to vigorous intensity activities (4% versus 5%; p<0.001). Overweight children spent significantly less time in moderate to vigorous intensity activities (4%) that normal weight children (45%, p<0.01). Parental education or ethnicity were not associated with time spent in sedentary or physical activities. CONCLUSIONS: European schoolchildren spend a small amount of their school-time in moderate to vigorous intensity activities and a large amount in sedentary activities, with small but significant differences across countries. Future interventions should target more physical activities and less sedentary time at school particularly in girls.

OBJECTIVE: The main objective was to assess the relationship of breakfast skipping, television (TV) viewing at breakfast and breakfast without TV with weight status among parents of 10-12-year-olds in eight European countries. DESIGN: A cross-sectional survey assessed breakfast eating and TV viewing at breakfast by three frequency questions and parents were categorized into: (i) breakfast skippers; (ii) breakfast with TV (TV watchers at breakfast); and (iii) breakfast without TV (breakfast eaters who do not watch TV during breakfast). Self-reported weight and height were used to categorize weight status as underweight, normal weight, overweight and obese. Multinomial logistic regression analyses were conducted with weight status as the dependent variable and breakfast habits as predictors, adjusting for sex, ethnicity and level of education. SETTING: The survey was conducted in 2010 in 199 primary schools across eight European countries participating in the ENERGY (EuropeaN Energy balance Research to prevent excessive weight Gain among Youth) cross-sectional study. SUBJECTS: Parents (n 6512) of 10-12-year-olds responded to the questionnaire. RESULTS: In the total study sample, with breakfast without TV as the reference group and adjusting for sex, ethnicity and level of education, the OR of being respectively overweight or obese (compared with normal weight) was 1·2 (95 % CI 1·0, 1·4) or 1·8 (95 % CI 1·5, 2·3) for breakfast skippers. The OR of being respectively underweight or obese was 0·5 (95 % CI 0·2, 0·9) or 1·4 (95 % CI 1·1, 1·8) for breakfast with TV. CONCLUSIONS: Breakfast skippers were significantly more likely to be overweight and obese, and those eating breakfast while watching TV were significantly more likely to be obese and less likely to be underweight.

BACKGROUND: The aim of the study was to examine the association of daily variations in rainfall and temperature with sedentary time (ST) and physical activity (PA) in European children. METHODS: Children were included from five countries (Belgium, Greece, Hungary, the Netherlands, Switzerland) as part of the ENERGY- project. We used cross-sectional data from 722 children aged 10-12 years (47% boys). ST and PA were measured by accelerometers for six consecutive days, including weekend days. Weather data was collected from online national weather reports. Multilevel regression models were used for data analyses. RESULTS: Maximum temperature was positively associated with light PA (b=3.1 min/day; 95% CI=2.4; 3.8), moderate-to-vigorous PA (b=0.6 min/day; 95% CI=0.4; 0.8) and average PA (b=4.1 counts per minute (cpm); 95% CI=1.6; 6.5, quadratic relationship). Rainfall was inversely and quadratically associated with light PA (b=-1.3 min/day; 95% CI=-1.9; -0.6), moderate-to-vigorous PA (b=-0.6 min/day; 95% CI=-0.8; -0.3) and average PA (b=-1.6 cpm; 95% CI=-2.2; -0.9). Maximum temperature was not significantly associated with ST (b=-0.2 min/day; 95% CI=-1.0; 0.6), while rainfall was positively associated with ST (b=0.9 min/day; 95% CI=0.6, 1.3). CONCLUSION: The present study shows that temperature and rainfall are significantly associated with PA and ST in 10-12 years European children.

We performed a systematic review and meta-analysis evaluating the effectiveness of exercise interventions compared with usual care on physical fitness, fatigue and health-related quality of life in patients with hematologic malignancies treated with stem cell transplantation. Electronic databases were searched up to June 2012. We included randomized controlled trials comparing exercise with usual care, in which at least 75% of the patients had a hematologic malignancy. Standard mean differences were calculated and pooled to generate summary effect sizes (ES) and 95% confidence intervals (CI). The Cochrane Collaboration Risk of Bias Tool was used to assess the methodological quality of the studies. Eight studies met our inclusion criteria. Exercise had a statistically significant moderately favourable effect on cardiorespiratory fitness (ES=0.53, 95% CI=0.13-0.94), lower extremity muscle strength (ES=0.56, 95% CI=0.18-0.94) and fatigue (ES=0.53, 95% CI=0.27-0.79). Significant small positive effects were found for upper extremity muscle strength, global quality of life, and physical, emotional and cognitive functioning. In conclusion, exercise seems to have beneficial effects in patients treated with stem cell transplantation. However, all studies had at least some risk of bias, and for cardiorespiratory fitness and lower extremity muscle strength substantial heterogeneity in effect sizes were observed. Further high quality research is needed to determine the optimal exercise intervention and clinical implications.

Socio-demographic and lifestyle-related characteristics associated with self-reported any, daily and occasional smoking during pregnancy.

Hide Abstract
Smoking during pregnancy is a risk factor for various adverse birth outcomes. In order to develop effective interventions, insight is needed into the characteristics associated with pregnant women who smoke. Unknown is whether these characteristics differ for women who smoke daily and women who smoke occasionally. Our study sample, drawn from the DELIVER study (Sept 2009-March 2011), consisted of 6107 pregnant women in primary care in the Netherlands who were up to 34 weeks pregnant. The associations of thirteen socio-demographic or lifestyle-related characteristics with any smoking, daily smoking and occasional smoking during pregnancy were tested using multiple binary logistic regression with general estimating equations (GEE). Characteristics most strongly associated with any smoking were low education (OR 10.3; 95% confidence interval (CI) 7.0-15.4), being of Turkish ethnicity (OR 3.9; 95%CI 2.3-6.7) and having no partner (OR 3.7; 95%CI 2.3-6.0). Women of Dutch ethnicity were three times more likely to smoke than those from Dutch-speaking Caribbean countries and non-religious women were much more likely to smoke than religious women. Low education was markedly more strongly associated with daily smoking than with occasional smoking (OR 20.3; 95%CI 13.2-31.3 versus OR 6.0; 95%CI 3.4-10.5). Daily smokers were more likely to be associated with other unfavorable lifestyle-related characteristics, such as not taking folic acid, being underweight, and having had an unplanned pregnancy. There is still much potential for health gain with respect to smoking during pregnancy in the Netherlands. Daily and occasional smokers appear to differ in characteristics, and therefore possibly require different interventions.

Mediating effects of home-related factors on fat intake from snacks in a school-based nutrition intervention among adolescents.

Hide Abstract
The purpose of the present study was to investigate if the effects of the parental component of a school-based intervention on dietary fat intake from snacking were mediated by changes in home-related factors. A random sample of 10 schools with 2232 pupils aged 11-15 years was randomly assigned to one of two intervention groups [one with (n = 1226) and one without a parental component (n = 1006)]. Fat intake, home availability of low-fat foods and parental encouragement and support to eat a low-fat diet were assessed with validated self-administered questionnaires. Mediation was assessed with the product-of-coefficient test. Changes in home-related determinants were significantly related to changes in fat intake from snacks; therefore, school-based obesity programmes on adolescents should try to address these determinants. In the present study, one of the three investigated home-related factors, namely parental support, was affected by the parental component intervention. Decreases in parental support were prevented. These changes in parental support were found to mediate the parental intervention effects on changes in fat intake from snacks. Home-related factors appear to be related to changes in adolescents snacking behaviours, therefore, school-based obesity programmes should target them. Nevertheless, more research is needed concerning effectively addressing the other determinants.

Hide Abstract
The aim of the present review was to examine the existing literature on the effectiveness of economic incentives for producing sound nutritional behavior in schools. Studies published in the English-language literature that included baseline and/or outcome data regarding food and beverage intake of schoolchildren were eligible for inclusion. A systematic search of the literature was conducted to identify relevant primary studies and relevant systematic reviews of primary studies. Altogether, 3,472 research publications were identified in the systematic search, of which 50 papers were retrieved. Of these, 30 publications representing 28 studies fulfilled the criteria for inclusion. The studies addressing price incentives suggest that such incentives are effective for altering consumption in the school setting. Other types of economic incentives have been included in combined intervention schemes, but the inclusion of other intervention elements makes it difficult to draw conclusions about the effectiveness of the economic incentive instruments per se in these studies.

Osteoporosis is a major health problem, and the economic burden is expected to rise due to an increase in life expectancy throughout the world. Current observational evidence suggests that an elevated homocysteine concentration and poor vitamin B12 and folate status are associated with an increased fracture risk. As vitamin B12 and folate intake and status play a large role in homocysteine metabolism, it is hypothesized that supplementation with these B-vitamins will reduce fracture incidence in elderly people with an elevated homocysteine concentration.

Home and neighbourhood correlates of BMI among children living in socioeconomically disadvantaged neighbourhoods.
Br. J. Nutr.

Show Abstract
Hide Abstract
A detailed understanding of the underlying drivers of obesity-risk behaviours is needed to inform prevention initiatives, particularly for individuals of low socioeconomic position who are at increased risk of unhealthy weight gain. However, few studies have concurrently considered factors in the home and local neighbourhood environments, and little research has examined determinants among children from low socioeconomic backgrounds. The present study examined home, social and neighbourhood correlates of BMI (kg/m2) in children living in disadvantaged neighbourhoods. Cross-sectional data were collected from 491 women with children aged 5-12 years living in forty urban and forty rural socioeconomically disadvantaged areas (suburbs) of Victoria, Australia in 2007 and 2008. Mothers completed questionnaires about the home environment (maternal efficacy, perceived importance/beliefs, rewards, rules and access to equipment), social norms and perceived neighbourhood environment in relation to physical activity, healthy eating and sedentary behaviour. Childrens height and weight were measured at school or home. Linear regression analyses controlled for child sex and age. In multivariable analyses, children whose mothers had higher efficacy for them doing physical activity tended to have lower BMI z scores (B = - 0·04, 95 % CI - 0·06, - 0·02), and children who had a television (TV) in their bedroom (B = 0·24, 95 % CI 0·04, 0·44) and whose mothers made greater use of food as a reward for good behaviour (B = 0·05, 95 % CI 0·01, 0·09) tended to have higher BMI z scores. Increasing efficacy among mothers to promote physical activity, limiting use of food as a reward and not placing TV in childrens bedrooms may be important targets for future obesity prevention initiatives in disadvantaged communities.

This study aims to explore whether objectively measured availability of parks and sports facilities within three different buffer sizes are associated with moderate-to-vigorous physical activity (MVPA) among adolescents, and to identify potential cognitive mediators of this association. Data were obtained from adolescents (N=209, mean age: 14.5 (SD: 0.6) years) at the follow-up measurement of the Children Living in Active Neighbourhoods study in 2004. MVPA was measured using accelerometers. Availability of parks and sport facilities were measured within 400, 800 and 2000 m buffers around participants residential homes. Potential mediators (self-efficacy, attitude and the perceived availability of parks and sports grounds) were measured by self-administered questionnaires. No direct association was found between the objectively measured availability of facilities and objective assessments of MVPA and no evidence for mediation by cognitions was found in any of the buffer sizes. More specific and sensitive measures may be needed to understand environmental correlates of MVPA.

Overweight and obesity in youth has increased dramatically. Therefore, overweight prevention initiatives should start early in life and target modifiable energy balance-related behaviours. Parental participation is often advocated as important for school-based interventions, however, getting parents involved in school-based interventions appears to be challenging based on earlier intervention experiences. The purpose of this study was to get insight into the determinants of and perspectives on parental participation in school-interventions on energy balance-related behaviours (physical activity, healthy eating, sedentary behaviours) in parents of ten- to twelve-year olds in order to develop an effective parental module for school-based interventions concerning energy balance-related behaviours.

The aim of this review was to systematically review the results and quality of studies investigating the moderators of school-based interventions aimed at energy balance-related behaviors. We systematically searched the electronic databases of Pubmed, EMBASE, Cochrane, PsycInfo, ERIC and Sportdiscus. In total 61 articles were included. Gender, ethnicity, age, baseline values of outcomes, initial weight status and socioeconomic status were the most frequently studied potential moderators. The moderator with the most convincing evidence was gender. School-based interventions appear to work better for girls than for boys. Due to the inconsistent results, many studies reporting non-significant moderating effects, and the moderate methodological quality of most studies, no further consistent results were found. Consequently, there is lack of insight into what interventions work for whom. Future studies should apply stronger methodology to test moderating effects of important potential target group segmentations.

Analogue to occupational noise-induced hearing loss, MP3-induced hearing loss may be evolving into a significant social and public health problem. To inform prevention strategies and interventions, this study investigated correlates of adolescents risky MP3-player listening behavior primarily informed by protection motivation theory. We invited 1687 adolescents (12- to 19-year old) of Dutch secondary schools to complete questionnaires about their MP3-player listening, sociodemographic characteristics and presumed psychosocial determinants of MP3-player listening. Of all participants, 90% reported listening to music through earphones on MP3 players; 28.6% were categorized as listeners at risk for hearing loss due to estimated exposure of 89 dBA for ?1 hour per day. Compared with listeners not at risk for hearing loss, listeners at risk were more likely not to live with both parents, to experience rewards of listening to high-volume levels, to report a high habit strength related to risky MP3 listening, and were less likely to be motivated to protect their hearing. Habit strength was the strongest correlate of risky listening behavior, suggesting that voluntary behavior change among adolescents might be difficult to achieve and that a multiple strategy approach may be needed to prevent MP3-induced hearing loss.

This study investigated the effectiveness of labeling foods with the Choices nutrition logo on influencing cafeteria menu selection and the behavioral determinants of menu choices in work site cafeterias in the Netherlands. A cluster randomized controlled trial was conducted. Intervention cafeterias (n=13), where the Choices logo was used to promote healthier eating for a 3-week period, were compared with control cafeterias (n=12), which offered the same menu without the logo. Sales data were collected daily for 9 weeks, from March to May 2009. In addition, employees from one intervention and one control company completed an online questionnaire at baseline and after the intervention (n=368) in which the behavioral determinants of food choice (ie, attitude, self-efficacy, and intention) and logo use were measured. Generalized estimating equation analyses, ?² tests, t tests and linear regression analyses were performed. No nutritionally meaningful intervention effects were found in the sales of sandwiches, soups, snacks, fruit, and salads. Also, no significant differences in behavioral determinants were found. "Intention to eat healthier" and "paying attention to product information" were positively associated with self-reported consumption of foods with the Choices logo at lunch. The intervention did not have a significant effect on employees lunchtime food choices. Labeling healthy choices might be useful for health-conscious employees in the volitional phase of behavior change. Further research should focus on the possible health benefits of menu reformulation in the catering sector.

The Internet is considered to be a promising delivery channel of interventions aimed at promoting healthful behaviors, especially for adolescents and young adults. Exposure to these interventions, however, is generally low. A more extensive exploration of methods, strategies, and their effectiveness with regard to facilitating exposure is therefore timely, because this knowledge is crucial to improve the use of such interventions and, subsequently, to increase behavioral change. Therefore, a systematic review of the literature was conducted, resulting in 838 studies based on title selection, of which 26 studies met the eligibility criteria. The systematic review resulted in an overview of methods and strategies that have been used to facilitate exposure. Patterns of effective strategies could be observed, such as the combination of tailored communication and the use of reminders and incentives. Nevertheless, exposure-specific theories need to be developed and objective exposure measures should be tracked and reported in future studies.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
