Are clusters of dietary patterns and cluster membership stable over time? Results of a longitudinal cluster analysis study.
Appetite
PUBLISHED: 03-24-2014
Show Abstract
Hide Abstract
Developing nutrition education interventions based on clusters of dietary patterns can only be done adequately when it is clear if distinctive clusters of dietary patterns can be derived and reproduced over time, if cluster membership is stable, and if it is predictable which type of people belong to a certain cluster. Hence, this study aimed to: (1) identify clusters of dietary patterns among Dutch adults, (2) test the reproducibility of these clusters and stability of cluster membership over time, and (3) identify sociodemographic predictors of cluster membership and cluster transition.

Despite decades of nutrition education, the prevalence of unhealthy dietary patterns is still high and inequalities in intake between high and low socioeconomic groups still exist. Therefore, it is important to innovate and improve existing nutrition education interventions. This paper describes the development, design and evaluation protocol of a web-based computer-tailored nutrition education intervention for adults targeting fruit, vegetable, high-energy snack and fat intake. This intervention innovates existing computer-tailored interventions by not only targeting motivational factors, but also volitional and self-regulation processes and environmental-level factors.

Motivational interviewing in a web-based physical activity intervention: questions and reflections.

Hide Abstract
The purpose of this study was to identify which question/reflection format leads to the most favorable results in terms of effect on autonomous motivation and appreciation for the intervention in a web-based computer-tailored physical activity (PA) intervention, based on principles from self-determination theory (SDT) and motivational interviewing (MI). For this purpose, a randomized trial was conducted among 465 Dutch adults, comparing three web-based computer-tailored MI/SDT PA interventions, including (i) exclusively open-ended questions (without skillful reflections), (ii) exclusively multiple choice questions (with skillful reflections) and (iii) including both question types (with skillful reflections). Measurements included motivation-related determinants of PA and process variables, measured at baseline, directly following the intervention and 1-month post-intervention. Results suggest that open-ended questions represent an important element in web-based MI in terms of effect on autonomous motivation. In order to optimize appreciation of the intervention, a combination of both open-ended and multiple choice question types seems to hold most promise. The findings of this study suggest that both open-ended and multiple choice questions should be included in web-based computer-tailored SDT/MI PA interventions. More research is needed to reveal the optimal configuration of this novel intervention type.

Show Abstract
Hide Abstract
This paper describes the systematic development of a text-driven and a video-driven web-based computer-tailored intervention aimed to prevent obesity among normal weight and overweight adults. We hypothesize that the video-driven intervention will be more effective and appealing for individuals with a low level of education.Methods and design: The Intervention Mapping protocol was used to develop the interventions, which have exactly the same educational content but differ in the format in which the information is delivered. One intervention is fully text-based, while in the other intervention in addition to text-based feedback, the core messages are provided by means of videos. The aim of the interventions is to prevent weight gain or achieve modest weight loss by making small changes in dietary intake or physical activity. The content of the interventions is based on the I-Change Model and self-regulation theories and includes behavior change methods such as consciousness raising, tailored feedback on behavior and cognitions, goal setting, action and coping planning, and evaluation of goal pursuit. The interventions consist of six sessions. In the first two sessions, participants will set weight and behavioral change goals and form plans for specific actions to achieve the desired goals. In the remaining four sessions, participants will evaluate their progress toward achievement of the behavioral and weight goals. They will also receive personalized feedback on how to deal with difficulties they may encounter, including the opportunity to make coping plans and the possibility to learn from experiences of others. The efficacy and appreciation of the interventions will be examined by means of a three-group randomized controlled trial using a waiting list control group. Measurements will take place at baseline and six and twelve months after baseline. Primary outcome measures are body mass index, physical activity, and dietary intake.

Associations of parental feeding styles with child snacking behaviour and weight in the context of general parenting.

Hide Abstract
OBJECTIVE: To examine cross-sectional and longitudinal (one-year follow-up) associations of parental feeding styles with child snacking behaviour and weight in the context of general parenting, taking into account the multidimensionality of the controlling feeding style. DESIGN: Linear regression analyses were performed. Parents completed a questionnaire to measure five feeding style dimensions (Instrumental Feeding, Emotional Feeding, Encouragement, Overt Control and Covert Control) and childrens fruit, energy-dense snack and sugar-sweetened beverage (SSB) intakes. Childrens height and weight were measured to calculate their BMI Z-scores. Moderation by parenting style was tested by adding interaction terms to the regression analyses. SETTING: Observational study in the Netherlands. SUBJECTS: Parent-child dyads (n 1275) participating in the INPACT (IVO Nutrition and Physical Activity Child cohorT) study; children were (on average) 9 years of age. RESULTS: Instrumental Feeding and Emotional Feeding were negatively related to child fruit intake one year later and positively to (changes in) child energy-dense snack intake. Encouragement was negatively related to child energy-dense snacking and SSB intake one year later. Overt Control was cross-sectionally and prospectively related to (changes in) child energy-dense snacking and SSB intake in a negative direction. Covert Control showed similar associations with child energy-dense snacking and SSB intake as Overt Control. Although Covert Control was also positively related to child fruit intake and (changes in) child BMI Z-score, bootstrapping analyses revealed only a differential effect of Overt Control and Covert Control on child BMI Z-score one year later, with Covert Control displaying a stronger, positive association. Moderation analyses showed that some significant associations between parental feeding styles and outcome measures were dependent on the degree of psychological control and behavioural control. CONCLUSIONS: Instrumental Feeding and Emotional Feeding may have a detrimental impact on childrens snacking behaviour, while Encouragement, Overt Control and Covert Control may lead to less energy-dense snacking and less SSB intake. Overt Control and Covert Control have differential effects on child BMI Z-score one year later, which supports the idea that they should be treated as separate constructs. Prospective studies with a longer follow-up may elucidate the causal pathways between the various feeding styles and childrens snacking behaviour and weight, as well as the moderating influences of psychological and behavioural control.

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.

This study examines the association between parental and child fruit consumption in the context of general parenting, parental education and ethnic background. A cross-sectional study was performed among 1762 parent-child dyads. Mean age of the children was 8 years. One parent completed a questionnaire to measure their own and their childs fruit consumption, parenting style, education level and ethnicity. In mediation and moderation analyses, child fruit consumption was regressed on parental fruit consumption, parenting style, parental education and ethnicity. Participating children consumed on average 7.5 pieces of fruit per week. Fourteen percent met the recommended Dutch norm of two pieces of fruit per day. Parental and child fruit consumption were positively associated. The association was more pronounced under higher levels of psychological control and behavioural control, and among ethnic groups. Additionally, parental education and child fruit consumption were positively associated. Parental fruit consumption partially mediated this association. Interventions are needed to increase child fruit consumption. Interventions should focus on increasing parental fruit consumption and positive parental modelling, with particular focus on low-SES families. Additionally, interventions that combine positive modelling with positive general parenting skills (e.g. increasing behavioural control) may be more effective than interventions that focus on parental modelling alone.

Hide Abstract
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.

Injuries in or around the home are the most important cause of death among children aged 0-4 years old. It is also a major source of morbidity and loss of quality of life. In order to reduce the number of injuries, the Consumer Safety Institute introduced the use of Safety Information Leaflets in the Netherlands to provide safety education to parents of children aged 0-4 years. Despite current safety education, necessary safety behaviours are still not taken by a large number of parents, causing unnecessary risk of injury among young children. In an earlier study an E-health module with internet-based, tailored safety information was developed and applied. It concerns an advice for parents on safety behaviours in their homes regarding their child. The aim of this study is to evaluate the effect of this safety information combined with personal counselling on parents child safety behaviours.

This longitudinal study aimed to identify individual and environmental predictors of adolescents sports participation and to examine whether availability of sports facilities moderated the intention-behaviour relation. Data were obtained from the ENvironmental Determinants of Obesity in Rotterdam SchoolchildrEn study (2005/2006 to 2007/2008). A total of 247 adolescents (48% boys, mean age at follow-up 15 years) completed the surveys at baseline and follow-up. At baseline, adolescents completed a survey that assessed engagement in sports participation, attitude, subjective norm, perceived behavioural control and intention towards sports participation. Availability of sports facilities (availability) was assessed using a geographic information system. At follow-up, sports participation was again examined. Multiple logistic regression analyses were conducted to test associations between availability of sports facilities, theory of planned behaviour variables and the interaction of intention by availability of sports facilities, with sports participation at follow-up. Simple slopes analysis was conducted to decompose the interaction effect. A significant availability x intention interaction effect [odds ratio: 1.10; 95% confidence interval: 1.00-1.20] was found. Simple slopes analysis showed that intention was more strongly associated with sports participation when sports facilities were more readily available. The results of this study indicate that the intention-sports participation association appears to be stronger when more facilities are available.

Hide Abstract
Cancer is one of the major causes of death in western countries. Fruit and vegetable consumption may reduce the risk of cancers of the oropharynx, oesophagus, lung, stomach and colorectum. We investigated the potential effect of interventions aimed at increasing the intake of fruits and vegetables to the recommended level (500 g/d) on future cancer incidence in Europe. Data on cancer incidence and daily intake of fruit and vegetables were compiled for France, Germany, The Netherlands, Spain and Sweden. We also performed a meta-analysis of European observational studies to arrive at a quantitative estimate on the association between fruit and vegetable intake and cancer risk. Predictions on the future cancer incidence were modelled using PREVENT 3.01. Our study predicted 212,000 fruit- and vegetable-related cancer cases in these countries in 2050, out of which 398 (0.19%) might be prevented if the 500 g/d fruit and vegetable intake were achieved in the aforementioned countries. The largest absolute impact was observed for lung cancer with 257 (out of 136,517) preventable cases if the intervention was successfully implemented. Sweden would benefit the most from intervention to increase fruit and vegetable consumption with a 2% reduction in expected cases. Increasing fruit and vegetable consumption has a small impact on reducing the burden of cancer in Europe. Health impact assessment tools such as PREVENT can provide the basis for decision making in chronic disease prevention.

Hide Abstract
Sugar-sweetened beverage (SSB) consumption may increase risk for unnecessary weight gain. To develop interventions discouraging consumption, more insight is needed about cognitive and environmental predictors related to the decrease in SSB consumption. The present paper aims (1) to describe the relationship between potential cognitive determinants of change (attitudes, subjective norms, perceived behavioural control and intentions) and perceived environmental factors (family food rule and home availability of SSB) with changes in SSB consumption between baseline and 4-month follow-up and (2) to study whether the relationships between the environmental factors and SSB consumption are mediated by the cognitive determinants. Information on possible predictors and SSB intake at baseline and 4-month follow-up was provided by 348 Dutch adolescents (aged 12-13 years) through online questionnaires that were completed at school. Multilevel logistic regression and mediation analyses were used to determine direct and indirect associations between predictors and behaviour. The present results show that a high perceived behavioural control to decrease intake at baseline was associated with a decrease in consumption of SSB between baseline and follow-up (OR = 0.53). Low availability and a stricter family food rule were associated with a decrease in SSB consumption between baseline and follow-up (OR = 2.39, 0.54). The association between availability and decrease in SSB consumption was for 68 % mediated by perceived behavioural control to drink less. In conclusion, interventions to decrease SSB intake should focus on improving attitudes and perceived behavioural control to reduce intake, and on limiting home availability and stimulating stricter family food rules regarding SSB consumption.

The Internet has become important for the delivery of behavior change interventions. This observational study examines how many people visited, registered and revisited a web-based computer-tailored intervention promoting heart-healthy behaviors when it is implemented for use by the general public. Among registered visitors, the association between visitors characteristics and initiating, completing and revisiting the website and/or its behavior-specific modules was analyzed. Server statistics showed that 285 146 visitors from unique IP addresses landed on the home page in a 36-month period; of these, >50% left the intervention website within 30 s. In total, 81 574 (28.6%) visitors completed the registration procedure and gained access to the intervention; 99% of registered visitors initiated one module, 91% completed at least one module and 6% revisited the intervention. The majority of the registered visitors were women, medium to highly educated, with a body mass index (BMI) <25. Women, visitors aged 40-50 years, visitors with a medium educational level and visitors with a BMI <25 were more likely to initiate and finish the modules. It is concluded that a heart-healthy computer-tailored Internet program can reach substantial numbers of people, but additional research is needed to develop promotional strategies that reach the high-risk population, i.e. men, older and lower educated persons.

The use of online word of mouth (WOM) seems a promising strategy to motivate young people to visit Internet-delivered interventions. An Internet-delivered intervention aimed at changing implicit attitudes related to alcohol was used in two experiments to test effectiveness of e-mail invitations on a first visit to the intervention. The results of the first experiment (N = 196) showed that an invitation by e-mail from a friend was more effective to attract young adults (aged 18-24 years) to the intervention website than an invitation from an institution. A 2 x 2 design was used in the second experiment (N = 236) to test manipulations of argument strength and the use of peripheral cues in invitations. Results showed that weak arguments were more effective to attract young adults to the intervention website when an incentive was withheld. These results need to be taken into account when using online WOM as a strategy to improve exposure to Internet-delivered interventions.

Hide Abstract
OBJECTIVE: To explore whether the effects on dietary behaviours of a computer-tailored intervention aimed to prevent excessive weight gain among adolescents, FATaintPHAT, were moderated by sociodemographic, cognitive and home environmental factors. DESIGN: A two-group cluster randomized trial. Potential moderation of the outcome measures (consumption of sugar-sweetened beverages, snacks, fruits and vegetables) was studied by gender, education level, ethnicity, awareness of risk behaviour, intention and home availability. SETTING: Twenty schools in the Netherlands. SUBJECTS: Students (n 883) aged 12-13 years. RESULTS: Of the twenty-four interactions tested, only three were significant. The intervention effect on sugar-sweetened beverages was moderated by level of education (P = 0·009); intervention effects were found only among academic preparatory students. The intervention effects on fruit and vegetable intake were moderated by awareness of fruit intake (P < 0·001) and home availability of vegetables (P = 0·007); an effect on fruit intake was found only among students who were aware of their low fruit intake at baseline and an effect on vegetable consumption was found only among students who reported that vegetables were always available at their home. CONCLUSIONS: The effects of the intervention generally did not differ between sociodemographic subgroups. The moderation by home availability illustrates that the environment may influence the effects of educational interventions.

Associations of childrens appetitive traits with weight and dietary behaviours in the context of general parenting.
PLoS ONE
Show Abstract
Hide Abstract
Individual variations in child weight can be explained by genetic and behavioural susceptibility to obesity. Behavioural susceptibility can be expressed in appetite-related traits, e.g. food responsiveness. Research into such behavioural factors is important, as it can provide starting points for (preventive) interventions.

Clustering of food and activity preferences in primary school children.
Appetite
Show Abstract
Hide Abstract
This study examined clustering of food and activity preferences in Dutch primary school children. It also explored whether the preference clusters are associated with child and parental background characteristics and with parenting practices. Data were used from 1480 parent-child dyads participating in the IVO Nutrition and Physical Activity Child cohort (INPACT). Children aged 8-11years reported their preferences for food (e.g. fruit and sweet snacks) and activities (e.g. biking and watching television) at school with a newly-developed, visual instrument designed for primary school children. Parents completed a questionnaire at home. Principal component analysis was used to identify preference clusters. Backward regression analyses were used to examine the relationship between child and parental characteristics with cluster scores. We found (1) a clustering of preferences for unhealthy foods and unhealthy drinks, (2) a clustering of preferences for various physical activity behaviours, and (3) a clustering of preferences for unhealthy drinks and sedentary behaviour. Boys had a higher cluster score than girls on all three preference clusters. In addition, physical activity-related parenting practices were negatively related to unhealthy preference clusters and positively to the physical-activity-preference cluster. The next step is to relate our preference clusters to child dietary and activity behaviours, with special attention to gender differences. This may help in the development of interventions aimed at improving childrens food and activity preferences.

Behavioral risk factors for overweight in early childhood; the Be active, eat right study.
Int J Behav Nutr Phys Act
Show Abstract
Hide Abstract
The lifestyle-related behaviors having breakfast, drinking sweet beverages, playing outside and watching TV have been indicated to have an association with childhood overweight, but research among young children (below 6 years old) is limited. The aim of the present study was to assess the associations between these four behaviors and overweight among young children.

A web-based computer-tailored smoking prevention programme for primary school children: intervention design and study protocol.
BMC Public Health
Show Abstract
Hide Abstract
Although the number of smokers has declined in the last decade, smoking is still a major health problem among youngsters and adolescents. For this reason, there is a need for effective smoking prevention programmes targeting primary school children. A web-based computer-tailored feedback programme may be an effective intervention to stimulate youngsters not to start smoking, and increase their knowledge about the adverse effects of smoking and their attitudes and self-efficacy regarding non-smoking.

Results from an online computer-tailored weight management intervention for overweight adults: randomized controlled trial.
J. Med. Internet Res.
Show Abstract
Hide Abstract
Prevention of weight gain has been suggested as an important strategy in the prevention of obesity and people who are overweight are a specifically important group to target. Currently there is a lack of weight gain prevention interventions that can reach large numbers of people. Therefore, we developed an Internet-delivered, computer-tailored weight management intervention for overweight adults. The focus of the intervention was on making small (100 kcal per day), but sustained changes in dietary intake (DI) or physical activity (PA) behaviors in order to maintain current weight or achieve modest weight loss. Self-regulation theory was used as the basis of the intervention.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

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.
