BackgroundThe built environment is increasingly recognized as a determinant for health and health behaviors. Existing evidence regarding the relationship between environment and health (behaviors) is varying in significance and magnitude, and more high-quality longitudinal studies are needed. The aim of this study was to evaluate the effects of a major urban redesign project on physical activity (PA), sedentary behavior (SB), active transport (AT), health-related quality of life (HRQOL), social activities (SA) and meaningfulness, at 29–39 months after opening of the reconstructed area.MethodsPA and AT were measured using accelerometers and GPS loggers. HRQOL and sociodemographic characteristics were assessed using questionnaires. In total, 241 participants provided valid data at baseline and follow-up. We distinguished three groups, based on proximity to the intervention area: maximal exposure group, minimal exposure group and no exposure group.ResultsBoth the maximal and minimal exposure groups showed significantly different trends regarding transport-based PA levels compared to the no exposure group. In the exposure groups SB decreased, while it increased in the no exposure group. Also, transport-based light intensity PA remained stable in the exposure groups, while it significantly decreased in the no exposure group. No intervention effects were found for total daily PA levels. Scores on SA and meaningfulness increased in the maximal exposure group and decreased in the minimal and no exposure group, but changes were not statistically significant.ConclusionThe results of this study emphasize the potential of the built environment in changing SB and highlights the relevance of longer-term follow-up measurements to explore the full potential of urban redesign projects.Trial registrationThis research was retrospectively registered at the Netherlands Trial Register (NL8108).

OBJECTIVE: The Samen Happie! app-based program aimed to stimulate healthy child weight development especially among families with a lower SEP, by encouraging healthy energy balance-related parenting practices. METHODS: A two-armed randomized controlled trial examined the process and effectiveness of the Samen Happie! program on child zBMI outcomes at 6- and 12-months follow-up. In total, 357 Dutch parents with infants aged 5-15 months old at baseline participated. Parents in the app condition (n = 179) received access to the Samen Happie! app and were compared to a waitlist-control condition (n = 178). Changes in zBMI were examined through linear mixed-effects models based on intention-to-treat and exploratory per-protocol principles. RESULTS: Process data showed low levels of sustained app use and moderate app acceptability. A general increase in child zBMI was observed in both conditions after 6 and 12 months. Intention-to-treat analyses using multiple imputations showed several statistically significant differences between conditions and high-risk subgroups. Specifically, at 6-months follow-up, zBMI increase was least pronounced in the app condition among children of parents with lower educational level. These findings were supported by exploratory per-protocol analyses including only frequent app users. In addition, per-protocol analyses showed benefits of app use at 6-months follow-up for children of parents with higher BMI. However, these effects were reversed at 12-months follow-up in both intention-to-treat and per-protocol analyses, where children of parents in the app condition in general increased the most in zBMI. CONCLUSIONS: This st

Contains fulltext : 231330.pdf (postprint version ) (Open Access), Background: The family environment plays an important role in the development of children's energy-balance related behaviors (EBRBs). As a result, parents' energy-balance parenting practices (EBRPPs) are eminent targets of preventive childhood obesity programs. Families with a lower socioeconomic position (SEP) may benefit from participating in such programs, but are generally less well reached than families with a higher SEP. Objective: This study describes the application of the Intervention Mapping Protocol (IMP) for the development of an app-based preventive intervention program to promote healthy EBRPPs among parents of children (0-4 years old) with a lower SEP. Methods: The six steps of the IMP were used as a theory- and evidence-based framework to guide the development of the app-based preventive intervention program. Results: In Step 1, behavioral outcomes for the app-based program (ie, children have a healthy dietary intake, sufficient sleep, and restricted screen time/sufficient physical activity) and socio-cognitive (ie, knowledge, attitudes, self-efficacy) and automatic (ie, habitual behaviors) determinants of energy-balance related parenting were identified through a needs assessment. In Step 2, the behavioral outcomes were translated into performance objectives. To influence these objectives, in Step 3 theory-based intervention methods were selected for each of the determinants. In Step 4, the knowledge derived from the previous steps allowed for the development of the app-based program Samen Happie! through a process of continuous co-creation with parents and health professionals. In Step 5, community health services were identified as potential adopters for the app. Lastly, in Step 6, two (randomized controlled) trials were designed to evaluate the process and effects of the app among Dutch parents of infants (Trial 1) and preschoolers (Trial 2). These trials were completed in November 2019 (Trial 1) and February 2020 (Trial 2). Conclusions: The IMP

This study explored associations between perceived neighborhood walkability and neighborhood-based physical activity (NB-PA) and assessed possible moderation effects of the amount of time spent in the home neighborhood and individual characteristics (i.e., educational level and health-related problems). In 2016 to 2017, 509 Dutch adults, living in the South Limburg area, were included. Context-specific PA levels were measured using the Actigraph GT3X+ accelerometer and the Qstarz BTQ1000XT GPS-logger. Perceived neighborhood walkability, level of education, work status, and health-related quality of life were measured with validated self-report instruments. Results showed that individuals with a lower level of education or health-related problems spent more time in the home neighborhood. The perceived neighborhood walkability only affected NB-PA for individuals spending a relatively large amount of time in their home neighborhood. PA-facilitating features in the home neighborhood, for example, aesthetics, were only associated with more NB-PA for individuals without health-related problems or with a higher level of education.

Contains fulltext : 216295.pdf (Publisher’s version ) (Closed access), Food recommendations increasingly focus on sustainability in addition to nutritional value. By providing participants with standard versus sustainable (plant-based) dietary recommendations for 3 weeks, the present research tested the impact of recommendations on dietary compliance. Furthermore, predictors of food intake were tested across food categories. Participants in the sustainable diet condition complied less with recommendations as compared to those in the standard diet condition and were less motivated to continue complying after the intervention. Taste was the main predictor of intake across food categories. Together, this stresses the importance of considering factors stimulating consumers' compliance when formulating food recommendations.

This paper describes the design of the LIKE programme, which aims to tackle the complex problem of childhood overweight and obesity in 10–14-year-old adolescents using a systems dynamics and participatory approach. The LIKE programme focuses on the transition period from 10-years-old to teenager and was implemented in collaboration with the Amsterdam Healthy Weight Programme (AHWP) in Amsterdam-East, the Netherlands. The aim is to develop, implement and evaluate an integrated action programme at the levels of family, school, neighbourhood, health care and city. Following the principles of Participatory Action Research (PAR), we worked with our population and societal stakeholders as co-creators. Applying a system lens, we first obtained a dynamic picture of the pre-exis

Background and aims: The efficacy of nutritional intervention to enhance short- and long-term outcomes of pulmonary rehabilitation in COPD is still unclear, hence this paper aims to investigate the clinical outcome and cost-effectiveness of a 12-month nutritional intervention strategy in muscle-wasted COPD patients. Methods: Prior to a 4-month pulmonary rehabilitation programme, 81 muscle-wasted COPD patients (51% males, aged 62.5 ± 0.9 years) with moderate airflow obstruction (FEV1 55.1 ± 2.2% predicted) and impaired exercise capacity (Wmax 63.5 ± 2.4% predicted) were randomized to 3 portions of nutritional supplementation per day (enriched with leucine, vitamin D and polyunsaturated fatty acids) [NUTRITION] or PLACEBO (phase 1). In the unblinded 8-month maintenance phase (phase 2), both groups received structured feedback on their physical activity level assessed by accelerometry. NUTRITION additionally received 1 portion of supplemental nutrition per day and motivational interviewing-based nutritional counselling. A 3-month follow-up (phase 3) was included. Results: A

Contains fulltext : 197324.pdf (publisher's version ) (Open Access), Increasing attention has been given to direct associations of general parenting styles with children's obesity. General parenting styles (i.e., authoritarian, authoritative, permissive, and uninvolved) refer to the broad emotional context reflecting childrearing across situations and domains (Darling and Steinberg, 1993). Parenting styles focus less on what parents do (i.e., behavior-specific parenting practices) and more on how they do it in general (Power, 2013). In this commentary, we argue that general parenting styles should be conceptualized as a contextual factor that may moderate the influence of weight-related (e.g., food) parenting practices on behavior and weight outcomes among children, as opposed to having direct effects on those outcomes.

Item does not contain fulltext, Although parents often report positive intentions to promote and create a healthy food environment for their children (e.g., setting limits to snacks offered), they also experience difficulties in translating these intentions into actual behaviors. In this position paper, we argue that automatic processes explain an important part of the gap between parents' intentions and their actual food parenting behaviors. We provide a conceptual framework in which we hypothesize that automatic effects on food parenting occur through two key interrelated constructs: habits (key outcome construct) and volitional regulation behaviors (key mediating construct). Moreover, we discuss potentially important impulse-focused techniques that may directly change habits (e.g., nudging; inhibitory control training) or indirectly through volitional regulation behaviors (e.g., implementation intentions; mental contrasting). We make use of the literature on the role of intention-behavior discordance in general health behaviors and discuss implications for food parenting practices. Our framework provides a dual process view towards food parenting and may help to explain when and why parents are likely to engage in (un)healthy food parenting behaviors. In addition, this framework may hopefully stimulate research on (combinations of old and) new techniques to promote good food parenting behaviors.

Background: Combined lifestyle interventions (CLIs) have proved to be effective in changing and maintaining behavioural lifestyle changes and reducing overweight and obesity, in clinical and real-world settings. In this CLI, lifestyle coaches are expected to promote lifestyle changes of participants regarding physical activity and diet. In the Coaching on Lifestyle (CooL) intervention, which takes a period of 8 to 10 months, lifestyle coaches counsel adults and children aged 4 years and older (and their parents) who are obese or are overweight with an increased risk of developing cardiovascular diseases or type II diabetes. In group and individual sessions, themes such as physical activity, dietary behaviours, sleep and stress are addressed. The aim of the present study is to monitor the implementation process of the CooL intervention and to examine how the lifestyle coaches contribute to a healthier lifestyle of the participants. Methods: This action-oriented study involves monitoring the implementation process of the CooL intervention and examining the lifestyle changes achieved by participants over time, in a one-group pre-post design using mixed methods. Methods include semi-structured interviews, observations, document analysis, biomedical parameters and questionnaires. Discussion: The added value of the CooL study lies in its action-oriented approach and the use of mixed methods, including both qualitative and quantitative research methods. The long-term coaching used in the CooL intervention is expected to have beneficial effects on sustained lifestyle changes.

Item does not contain fulltext, Objective/background: The inverse relationship between sleep duration and body mass index (BMI) has been well established and appears to be stronger among boys than girls. However, less is known about the mechanisms responsible for this sex-specific link. The main aim of the current study was to examine the sex-specific interaction between food responsiveness and sleep duration in explaining BMI among children. This sex-specific moderation will give more insight into a possible underlying food intake mechanism. Patients/methods: In total, 206 caregivers filled out questionnaires on child's sleep duration and food responsiveness (49.5% boys; mean age = 9.5 years; standard deviation = 1.4 years). Child's weight and height were measured, after which age- and sex-specific standardized BMI values (referred to as zBMI here) were calculated. Descriptive statistics and regression analysis were conducted. A potential significant three-way interaction was further examined using simple slopes analysis and slope difference tests. Results: A significant inverse correlation was found between sleep duration and zBMI for boys, but not for girls. Moreover, a significant and robust three-way interaction between sex, food responsiveness and sleep duration explaining child's zBMI was found. Slope difference tests indicate that the sleep-BMI slopes only significantly differed between high-food-responsive boys and high-food-responsive girls and between high-food-responsive boys and low-food-responsive boys. Conclusions: These findings suggest that increased food intake might be a mechanism explaining the inverse sleep-BMI link among boys.

Background The role of health broker is a relatively new one in public health. Health brokers aim to create support for efforts to optimise health promotion in complex or even “wicked” public health contexts by facilitating intersectoral collaborations and by exchanging knowledge with different stakeholders. The current study aimed to explore the role of health brokers, by examining the motivational, contextual, and behaviour-related factors they have to deal with. Methods Fifteen professionals from various backgrounds and from various policy and practice organisations were recruited for a semistructured interview. To structure the interviews, we developed the “Health Broker Wheel” (HBW), a framework we then specified with more details derived from the interviews. Results We identified seven primary types of behaviour that health brokers need to engage in: recognizing opportunities, agenda setting, implementing, network formation, intersectoral collaboration, adaptive managing, and leadership. Determinants of health brokers’ behaviours were identified and categorised as capability, opportunities, motivation, and local or national contextual factors. Conclusion The health brokers’ role can be seen as an operational approach and is visualised in the HBW. This framework can assist further research to monitor and evaluate this role, and health promotion practitioners can use it as a tool to implement the health brokers’ role and to facilitate intersectoral collaboration.

Motivational stages of adolescent smoking initiation: predictive validity and predictors of transitions. Kremers SP, de Vries H, Mudde AN, Candel M. Department of Health Education and Health Promotion, Faculty of Health Sciences, Universiteit Maastricht, P.O. Box 616, 6200 MD Maastricht, The Netherlands. s.kremers@gvo.unimaas.nl The present study tested the use and validity of a stage model of adolescent smoking initiation. The model aims to identify adolescents who are currently not smoking, but who are cognitively predisposed to start smoking in the future. Research on subtypes within the precontemplation stage of adolescent smoking initiation and the concept of susceptibility to smoking led to the construction of a motivational stage model of four distinct stages: committer, immotive, progressive, and contemplator. Using longitudinal data on a large international sample of European adolescents (n=7117), the model proved to have value in predicting smoking initiation at 12 months follow up. The odds ratio to take up regular smoking behavior appeared to double with each forward stage transition. Although effect sizes were small to moderate, unique predictors of transitions from the various stages were identified. Implications of the findings are discussed

Item does not contain fulltext, The aim of the study is to assess the impact of perceived and objective changes in greenery on physical activity and mental health of adolescents and adults living in severely deprived neighborhoods in the Netherlands. Longitudinal data regarding changes in greenery, walking, cycling, and depressive symptoms (CES-D), were gathered for 401 adolescents and 454 adults, using questionnaires and interviews with local district managers. Multivariate linear regression models examined the association between greenery and outcome variables, correcting for demographic and socioeconomic covariates and season. Overall, the results showed small and non-significant associations, with two exceptions. Objective improvements in greenery were associated with smaller decline in adolescents' leisure time cycling, and improvements in perceived greenery were related to a decrease in adults' depressive symptoms. In addition, there were several subgroup effects. In conclusion, changes in greenery did not yield consistent positive results among residents of severely deprived neighborhoods. However, there are some indications regarding positive effects of greenery in certain subgroups.

Background. Limited physical activity (PA) is a risk factor for childhood obesity. In Netherlands, as in many other countries worldwide, local policy officials bear responsibility for integrated PA policies, involving both health and nonhealth domains. In practice, its development seems hampered. We explore which obstacles local policy officials perceive in their effort. Methods. Fifteen semistructured interviews were held with policy officials from health and nonhealth policy domains, working at strategic, tactic, and operational level, in three relatively large municipalities. Questions focused on exploring perceived barriers for integrated PA policies. The interviews were deductively coded by applying the Behavior Change Ball framework. Findings. Childhood obesity prevention appeared on the governmental agenda and all officials understood the multicausal nature. However, operational officials had not yet developed a tradition to develop integrated PA policies due to insufficient boundary-spanning skills and structural and cultural differences between the domains. Tactical level officials did not sufficiently support intersectoral collaboration and strategic level officials mainly focused on public-private partnerships. Conclusion. Developing integrated PA policies is a bottom-up innovation process that needs to be supported by governmental leaders through better guiding organizational processes leading to such policies. Operational level officials can assist in this by making progress in intersectoral collaboration visible.

Background Strong longitudinal evidence exists that psychological distress is associated with a high morbidity and mortality risk in type 2 diabetes. Little is known about the biological and behavioral mechanisms that may explain this association. Moreover, the role of personality traits in these associations is still unclear. In this paper, we first describe the design of the psychological part of The Maastricht Study that aims to elucidate these mechanisms. Next, we present exploratory results on the prevalence of depression, anxiety and personality traits in type 2 diabetes. Finally, we briefly discuss the importance of these findings for clinical research and practice. Methods We measured psychological distress and depression using the MINI diagnostic interview, the PHQ-9 and GAD-7 questionnaires in the first 864 participants of The Maastricht Study, a large, population-based cohort study. Personality traits were measured by the DS14 and Big Five personality questionnaires. Type 2 diabetes was assessed by an oral glucose tolerance test. Logistic regression analyses were used to estimate the associations of depression, anxiety and personality with type 2 diabetes, adjusted for age, sex and education level. Results Individuals with type 2 diabetes had higher levels of depressive and anxiety symptoms, odds ratios (95 % CI) were 3.15 (1.49; 6.67), 1.73 (0.83–3.60), 1.50 (0.72–3.12), for PHQ-9 ≥ 10, current depressive disorder and GAD-7 ≥ 10, respectively. Type D personality, social inhibition and negative affectivity were more prevalent in type 2 diabetes, odds ratios were 1.95 (1.23–3.10), 1.35 (0.93–1.94) and 1.70 (1.14–2.51), respectively. Individuals with type 2 diabetes were less extraverted, less conscientious, less agreeable and less emotionally stable, and similar in openness to individuals without type 2 diabetes, although effect sizes were small. Conclusions Individuals with type 2 diabetes experience more psychological distress
