RESUMO
BACKGROUND: In the city of Maastricht in the Netherlands, a highway crossing several deprived neighborhoods was tunneled in 2016. The vacant space on top of this tunnel was redesigned and prioritized for pedestrians and cyclists. The aim of this study was to evaluate the effect of this major infrastructural change, named the Green Carpet, on total and transport-based physical activity (PA) levels. METHODS: Participants (≥18 years) were part of one of three area-based exposure groups. The maximal exposure group lived in neighborhoods directly bordering the Green Carpet. The minimal exposure group consisted of individuals living at the other side of the city, and the no exposure group consisted of individuals living in a nearby city. Actual use of the new infrastructure was incorporated as a second measure of exposure. Data were collected before and 3-15 months after the opening of the Green Carpet. Device-based measurements were conducted to obtain PA levels and collect location data. Changes in PA over time and intervention effects were determined using linear mixed models. RESULTS: PA levels in the Green Carpet area increased for the maximal and minimal exposure groups, but did not lead to an increase in total or transport-based PA. For the no exposure group, transport-based MVPA decreased and transport-based SB increased. The significant interaction (time x exposure) for transport-based SB, indicated differences in trends between the no exposure and maximal exposure group (B=-3.59, 95% CI - 7.15; -0.02) and minimal exposure group (B= -4.02, 95% CI -7.85, -0.19). Trends in the results based on analyses focusing on actual use and non-use of the new infrastructure were similar to those of the area-based analyses. CONCLUSIONS: Results suggest that the Green Carpet led to more PA in this specific area, but did not increase the total volume of PA. The area-based differences might reflect the differences between users and non-users, but we should be careful when interpreting these results, due to possible interference of selective mobility bias. This paper reflects that the relationship between infrastructure and PA is not unambiguous. TRIAL REGISTRATION: This research was retrospectively registered at the Netherlands Trial Register ( NL8108 ).

Drug use disorder is a major public health problem. Once people who use drugs (PWUD) are referred to treatment, addressing their lifestyle practices and improving their quality of life improves treatment outcomes. The present study assessed the nutritional status and lifestyle practices among PWUD undergoing treatment for recovery in Lebanon. Furthermore, it explored significant differences in these parameters depending on the offered treatment modality, namely opioid substitution treatment (OST) and rehabilitation. In total, 187 PWUD undergoing treatment for recovery participated in this cross-sectional study. Nutritional status and anthropometrics, dietary intake, nutrition knowledge, food addiction, biochemical parameters, sleep and physical activity were measured using validated tools. Of the participants, 88â 8 % were well nourished based on the Subjective Global Assessment. In total, 67 % gained weight during treatment placing them in the overweight category. This increase in weight was significantly higher in the rehabilitation group. It came in parallel with higher protein and energy intakes, higher rate of food addiction, and poor nutrition knowledge. Biochemical parameters, including fasting blood sugar, total protein, lipid profile and white blood cell count, were in the normal ranges. Moreover, the majority of participants exhibited poor quality sleep that was accentuated among the participants undergoing rehabilitation, in addition to activity levels that were mainly low in the OST group. PWUD undergoing treatment for recovery in Lebanon are subject to various vulnerability factors creating challenges to treatment. Longitudinal assessments to better understand health problems arising during treatment and to identify the components of a comprehensive health promotion intervention during treatment for recovery are needed.

BACKGROUND: Iran has a low incidence but higher rate of death from cervical cancer (CC). The country is in the process of implementing an organized screening program including HPV testing and cytology. Studies show high dropout in continued testing among eligible women. This qualitative study aimed to explore women's awareness regarding CC and CC testing and the role of knowledge, perceived risk, and cues to action in this process. METHOD: Through a qualitative study based on the Framework Method, we recruited 81 women aged 25-65 who participated in 15 focus group discussions (FGDs) and two in-depth interviews in Tehran. The interviewees were selected purposefully during January to May 2015 from households belonging to different socioeconomic classes until data saturation. The data were acquired through 11 open-ended questions and 32 related probe questions. All interviews were transcribed and independently analyzed by two researchers (Kappa and agreement testing respectively: 0.77, 97.11%). RESULTS: The coded texts were categorized under three themes and 13 subthemes. The three thematic areas referred to knowledge, cues to action, and perceived risks regarding CC and screening. The results showed that women had limited and unspecified knowledge about CC and screening, compounded by misconceptions regarding infection and cancer prevention measures. Social and cultural barriers hindered proper communication between health system/providers and clients and within communities on subjects related to CC and screening. The perceived risk of getting CC was low because of overestimating the role of hereditary factors for CC, difficulty in differentiating between cancer and sexually transmitted infections (STI), and the absence of visible symptoms. CONCLUSION: The results indicate a strong need to invest more efforts to improve health education and communication in the current national health program to promote awareness of the need to screen for CC through, for example, establishing correct knowledge and risk perceptions among women. In addition, this intervention should address women's social environment in order to prevent misconceptions being communicated to women.

INTRODUCTION: An increased smoking uptake by Saudi male adolescents and a lack of data about its determinants emphasize the need for a better understanding of factors leading to the onset of smoking and identifying ways to prevent it. The aim of this qualitative study is to explore adolescents' views on smoking and their opinions about a smoking prevention program. METHODS: A total of 103 school-going adolescents, aged 12-16 years, were purposely selected from grades seven, eight and nine from nine schools in Taif in Saudi Arabia. They were interviewed in 11 focus group discussions; five groups were held for smokers and six for non-smokers. An interview scheme was developed based on the I-Change Model, a model used for understanding smoking onset and prevention. We used QDA Lite version 2:0 software for data analysis. RESULTS: Most of the participants agreed on the importance of social influences as determining factors to start smoking. The presence of smoking friend(s) and family member(s), especially the father, were mentioned. Factors such as having extra pocket money, absence of alternatives, showing off, to be seen as western, to be seen as an adult and the good taste of cigarettes were also mentioned as beliefs associated with smoking. Adolescents indicated to have low confidence not to smoke under peer pressure, suggesting self-efficacy problems. Intentions to smoke were also often mentioned. Almost all participants agreed that an interactive approach is optimal for an effective smoking prevention program. CONCLUSIONS: Determinants of smoking seem to be very similar to those outlined by previous studies. A smoking prevention program for Saudi adolescents should address how to cope with social pressure to smoke, the advantages connected with smoking, and how to increase self-efficacy. Information should be presented in an interactive rather than static way.
RESUMO
INTRODUCTION: Knowing country-specific predictors of smoking behaviour for adolescents is crucial for successful smoking prevention programs. This study aims to assess demographic and socio-cognitive variables related to smoking initiation among Saudi male adolescents. METHODS: Longitudinal data were collected at T1 (baseline) and at T2 (followup at 6 months) using a self-administered questionnaire. We assessed smoking behaviour and related demographic variables and socio-cognitive variables. Chi-squared tests and independent-samples t-tests were used to identify differences in baseline characteristics between smokers and non-smokers at T1. Furthermore, non-smokers at T1 were included in logistic regression analyses to examine the predictors of smoking initiation between T1 and T2. RESULTS: At T1, the non-smokers who were included in further analysis were 523 (84.9%) of whom 48 (9.2%) had initiated smoking at T2. They differed significantly from non-initiators, including having a more positive attitude towards smoking, reporting more social norms, modelling and pressure to smoke, having a lower self-efficacy to refrain from smoking and higher intention to smoke in the future (all p<0.001). The regression analysis revealed that: adolescents with disrupted-families, being of low academic achievement, with relatively high monthly-income families, having more smoking-peers, high-perceived pressure to smoke from parents (p=0.002) and teachers (p=0.001), have smoking supportive-norms of parents and having high intention to smoke in the future (p<0.001) were at higher risk of being smokers. CONCLUSIONS: Findings suggest that health-promoting programs should address strengthening of self-efficacy and enhancing refusal skills against modelling of peers, pressure and norms of parents.
RESUMO
PROBLEM: Samoa has been struggling to address the burden of noncommunicable diseases at the health system, community and individual levels. APPROACH: The World Health Organization (WHO) package of essential noncommunicable disease interventions for primary health care in low-resource settings was adopted in seven villages throughout Samoa in 2015. The National Steering Committee Members designed and implemented a screening process, and local facilitators and health-care workers collected health and lifestyle data. The WHO/International Society of Hypertension risk assessment was used on villagers older than 40 years to identify people at high risk of noncommunicable disease. LOCAL SETTING: Samoa is a small island developing state with increasing morbidity and mortality due to noncommunicable diseases. A national representative survey indicated that 50.1% (595/1188) of the Samoan adult population is at high risk of such diseases. High numbers of noncommunicable diseases are undiagnosed or untreated, because of shortage of health-care staff and lack of awareness of risk factors. RELEVANT CHANGES: The teams collected data from 2234 adults. For people older than 40 years, 6.7% (54/804) were identified as being at high-risk and were encouraged to seek treatment or manage risk factors. Community members developed an awareness programme to improve understanding of lifestyle risk factors. LESSONS LEARNT: Engaging community members was crucial in conducting a successful screening campaign. By identifying those villagers at high risk of developing noncommunicable diseases, early intervention was possible. Education improved awareness of the symptom-free nature of early-stage noncommunicable diseases.

INTRODUCTION: Transnational tobacco company (TTC) submissions to the 2012 UK standardised packaging consultation are studied to examine TTC argumentation in the context of Better Regulation practices. METHODS: A content analysis was conducted of Philip Morris International and British American Tobacco submissions to the 2012 UK consultation. Industry arguments concerning expected costs and (contested) benefits of the policy were categorised into themes and frames. The inter-relationship between frames through linked arguments was mapped to analyse central arguments using an argumentation network. RESULTS: 173 arguments were identified. Arguments fell into one of five frames: ineffectiveness, negative economic consequences, harm to public health, increased crime or legal ramifications. Arguments highlighted high costs to a wide range of groups, including government, general public and other businesses. Arguments also questioned the public health benefits of standardised packaging and highlighted the potential benefits to undeserving groups. An increase in illicit trade was the most central argument and linked to the greatest variety of arguments. CONCLUSIONS: In policy-making systems characterised by mandatory impact assessments and public consultations, the wide range of cost (and contested benefits) based arguments highlights the risk of TTCs overloading policy actors and causing delays in policy adoption. Illicit trade related arguments are central to providing a rationale for these arguments, which include the claim that standardised packaging will increase health risks. The strategic importance of illicit trade arguments to industry argumentation in public consultations underlines the risks of relying on industry data relating to the scale of the illicit trade.

The aim of this cross-sectional school-based study was to assess smoking prevalence, indicators for the smoking epidemic and determinants of smoking among Saudi adolescents. The study included 695 male adolescents from 11 to 16 years of age who filled out self-report questionnaires based on the European Smoking Framework Approach questionnaire, which uses the I-Change model to assess attitude, social influence and the self-efficacy of the participants. Smokers were 275 (39.6%) adolescents. Smokers tended to receive more daily pocket money, live in more affluent families and show lower academic performance. Non-smokers were inclined to believe that smoking may help people to feel relaxed and confident, encountered less social influences to smoke than smokers, but reported low self-efficacy not to smoke when with smoker friends and when offered a cigarette. Smokers reported the lowest self-efficacy not to smoke in all situations assessed. The results suggest the smoking epidemic among male Saudi adolescents may still be in the early stages, providing ample opportunity for preventive actions aimed at halting the further progress of this epidemic. Secondly, smoking prevention programs in Saudi Arabia need to reinforce non-smoking attitudes, address how to resist pressure to smoke, and how to develop high self-efficacy towards non-smoking in various situations.

Previously, a Dutch randomized controlled trial evaluating an intervention aimed at changing adolescents' cannabis use, called Moti-4, has shown its efficacy. A secondary analysis of the Moti-4 data investigated the process of change specified by the Stage of Change (SOC) model in cannabis use during the trial. Seventy-one Moti-4 participants and 60 controls were recruited for the study with a pre-test, post-test (T1), and six-month follow-up (T2). All participants showed signs of problematic cannabis use. No contribution of the Moti-4 intervention to a change in SOC between T1 and T2 was found. Although motivation for treatment and motivation for change can be conceived as independent predictors of treatment outcome, the SOC a person is in does not mediate the effect of the intervention on change in cannabis use. However, a reduction in cannabis use was associated with a positive change in "action willingness," in line with the SOC model. In contrast to model expectations, a higher score on "contemplation" is associated with a higher cannabis consumption. Results highlight both the limitations and usefulness of the SOC model. Future interventions may focus more on the stage of "action willingness," as well as on perceived social norms.

OBJECTIVE: To examine the efficacy of a smoking prevention program which aimed to address smoking related cognitions and smoking behavior among Saudi adolescents age 13 to 15. METHOD: A randomized controlled trial was used. Respondents in the experimental group (N=698) received five in-school sessions, while those in the control group (N=683) received no smoking prevention information (usual curriculum). Post-intervention data was collected six months after baseline. Logistic regression analysis was applied to assess effects on smoking initiation, and linear regression analysis was applied to assess changes in beliefs and analysis of covariance (ANCOVA) was used to assess intervention effects. All analyses were adjusted for the nested structure of students within schools. RESULTS: At post-intervention respondents from the experimental group reported in comparison with those from the control group a significantly more negative attitude towards smoking, stronger social norms against smoking, higher self-efficacy towards non-smoking, more action planning to remain a non-smoker, and lower intentions to smoke in the future. Smoking initiation was 3.2% in the experimental group and 8.8% in the control group (p<0.01). CONCLUSION: The prevention program reinforced non-smoking cognitions and non-smoking behavior. Therefore it is recommended to implement the program at a national level in Saudi-Arabia. Future studies are recommended to assess long term program effects and the conditions favoring national implementation of the program.

Introduction Osteodystrophy management includes dietary phosphorus restriction, which may limit protein intake, exacerbate malnutrition-inflammation syndrome and mortality among hemodialysis patients. Methods A multicenter randomized controlled trial was conducted in Lebanon, to test the hypothesis that intensive nutrition education focused on phosphorus-to-protein balance will improve patient outcomes. Six hemodialysis units were randomly assigned to the trained hospital dietitian (THD) protocol (210 patients). Six others (184 patients) were divided equally according to the patients' dialysis shifts and assigned to Dedicated Dietitian (DD) and Control protocols. Patients in the THD group received nutrition education from hospital dietitians who were trained by the study team on renal dietetics, but had limited time for hemodialysis patients. Patients in the DD group received individualized nutritional education on dietary phosphorus and protein management for 6 months (2-hour/patient/month) from study renal dietitians. Patients in the control group continued receiving routine care from hospital dietitians who had limited time for these patients and were blinded to the study. Serum phosphorus (mmol/L), malnutrition-inflammation score (MIS), health-related quality of life (HRQOL) index and length of hospital stay (LOS) were assessed at T0 (baseline), T1 (postintervention) and T2 (post6 month follow up). Findings Only the DD protocol significantly improved serum phosphorus (T0:1.78 ± 0.5, T1:1.63 ± 0.46, T2:1.69 ± 0.53), 3 domains of the HRQOL and maintained MIS at T1, but this protective effect resolved at T2. The LOS significantly dropped for all groups. Discussion The presence of competent renal dietitians fully dedicated to hemodialysis units was superior over the other protocols in temporarily improving patient outcomes.

INTRODUCTION: The Dutch implementation of the black border provision in the 2001 European Union Tobacco Products Directive (TPD) is studied to examine the implications of tobacco industry involvement in the implementation phase of the policy process. METHODS: A qualitative analysis was conducted of Dutch government documents obtained through Freedom of Information Act requests, triangulated with in-depth interviews with key informants and secondary data sources (publicly available government documents, scientific literature, and news articles). RESULTS: Tobacco manufacturers' associations were given the opportunity to set implementation specifications via a fast-track deal with the government. The offer of early implementation of the labelling section of the TPD was used as political leverage by the industry, and underpinned by threats of litigation and arguments highlighting the risks of additional public costs and the benefits to the government of expediency and speed. Ultimately, the government agreed to the industry's interpretation, against the advice of the European Commission. CONCLUSIONS: The findings highlight the policy risks associated with corporate actors' ability to use interactions over technical product specifications to influence the implementation of health policy and illustrate the difficulties in limiting industry interference in accordance with Article 5.3 of the Framework Convention on Tobacco Control (FCTC). The implementation phase is particularly vulnerable to industry influence, where negotiation with industry actors may be unavoidable and the practical implications of relatively technical considerations are not always apparent to policymakers. During the implementation of the new TPD 2014/40/EU, government officials are advised to take a proactive role in stipulating technical specifications.

Integrated public health policy (IPHP) aims at integrating health considerations into policies of other sectors. Since the limited empirical evidence available may hamper its further development, we systematically analysed empirical manifestations of IPHP, by placing policy strategies along a continuum of less-to-more policy integration, going from intersectoral action (IA) to healthy public policy (HPP) to health in all policies (HiAP). Our case study included 34 municipal projects of the Dutch Gezonde Slagkracht Programme (2009-15), which supports the development and implementation of IPHP on overweight, alcohol and drug abuse, and smoking. Our content analysis of project application forms and interviews with all project leaders used a framework approach involving the policy strategies and the following policy variables: initiator, actors, policy goals, determinants and policy instruments. Most projects showed a combination of policy strategies. However, manifestations of IPHP in overweight projects predominantly involved IA. More policy integration was apparent in alcohol/drugs projects (HPP) and in all-theme projects (HiAP). More policy integration was related to broad goal definitions, which allowed for the involvement of actors representing several policy sectors. This enabled the implementation of a mix of policy instruments. Determinants of health were not explicitly used as a starting point of the policy process. If a policy problem justifies policy integration beyond IA, it might be helpful to start from the determinants of health (epidemiological reality), systematically transform them into policy (policy reality) and set broad policy goals, since this gives actors from other sectors the opportunity to participate.

PURPOSE: With the increasing burden of noncommunicable disease, adolescence is viewed as an opportune time to prevent the onset of certain behaviors and promote healthy states. Although adolescents comprise a considerable portion of Saudi Arabia's population, they have received insufficient attention and indicators of their health status, as a first step in a prevention cycle are unavailable. This study was carried out with the aim of identifying the health risk behaviors and health status of adolescents in Saudi Arabia. METHODS: This cross-sectional, school-based study was carried out in all 13 regions of Saudi Arabia. Through multistage, cluster, random sampling, intermediate, and secondary school students were invited to participate. Data were collected by means of a self-administered questionnaire addressing health risk behaviors and health status, clinical anthropometric measurements, and laboratory investigations. RESULTS: A total of 12,575 adolescents participated. Various health risk behaviors, including dietary and sedentary behaviors, lack of safety measures, tobacco use, bullying, and violence were highly prevalent. Twenty-eight percent of adolescents reported having a chronic health condition, 14.3% reported having symptoms suggestive of depression, 30.0% were overweight/obese, and 95.6% were vitamin D deficient. CONCLUSION: Behaviors and conditions known to persist into adulthood and result in morbidity and premature mortality are prevalent among adolescents in Saudi Arabia. Preventive measures and local health policies are urgently needed and can impact adolescents and future adults. Establishing adolescent health surveillance is necessary to monitor trends and impacts of such measures.

OBJECTIVE: Assess the effect of intensive nutrition education by trained dedicated dietitians on osteodystrophy management among hemodialysis patients. METHODS: Randomized controlled trial in 12 hospital-based hemodialysis units equally distributed over clusters 1 and 2. Cluster 1 patients were either assigned to usual care (n=96) or to individualized intensive staged-based nutrition education by a dedicated renal dietitian (n=88). Cluster 2 patients (n=210) received nutrition education from general hospital dietitians, educating their patients at their spare time from hospital duties. Main outcomes were: (1) dietary knowledge(%), (2) behavioral change, (3) serum phosphorus (mmol/L), each measured at T0 (baseline), T1 (post 6 month intervention) and T2 (post 6 month follow up). RESULTS: Significant improvement was found only among patients receiving intensive education from a dedicated dietitian at T1; the change regressed at T2 without statistical significance: knowledge (T0: 40.3; T1: 64; T2: 63) and serum phosphorus (T0: 1.79; T1: 1.65; T2: 1.70); behavioral stages changed significantly throughout the study (T0: Preparation, T1: Action, T2: Preparation). CONCLUSION: The intensive protocol showed to be the most effective. PRACTICE IMPLICATIONS: Integrating dedicated dietitians and stage-based education in hemodialysis units may improve the nutritional management of patients in Lebanon and countries with similar health care systems.

INTRODUCTION: Lifestyle Triple P is a general parenting intervention which focuses on preventing further excessive weight gain in overweight and obese children. The objective of the current study was to assess the effectiveness of the Lifestyle Triple P intervention in the Netherlands. METHOD: We used a parallel randomized controlled design to test the effectiveness of the intervention. In total, 86 child-parent triads (children 4-8 years old, overweight or obese) were recruited and randomly assigned (allocation ratio 1:1) to the Lifestyle Triple P intervention or the control condition. Parents in the intervention condition received a 14-week intervention consisting of ten 90-minute group sessions and four individual telephone sessions. Primary outcome measure was the children's body composition (BMI z-scores, waist circumference and skinfolds). The research assistant who performed the measurements was blinded for group assignment. Secondary outcome measures were the children's dietary behavior and physical activity level, parenting practices, parental feeding style, parenting style, and parental self-efficacy. Outcome measures were assessed at baseline and 4 months (short-term) and 12 months (long-term) after baseline. Multilevel multiple regression analyses were conducted to determine the effect of the intervention on primary and secondary outcome measures. RESULTS: No intervention effects were found on children's body composition. Analyses of secondary outcomes showed positive short-term intervention effects on children's soft-drink consumption and parental responsibility regarding physical activity, encouragement to eat, psychological control, and efficacy and satisfaction with parenting. Longer-term intervention effects were found on parent's report of children's time spent on sedentary behavior and playing outside, parental monitoring food intake, and responsibility regarding nutrition. CONCLUSION: Although the Lifestyle Triple P intervention showed positive effects on some parent reported child behaviors and parenting measures, no effects were visible on children's body composition or objectively measured physical activity. Several adjustments of the intervention content are recommended, for example including a booster session. TRIAL REGISTRATION: Nederlands Trial Register NTR 2555.

BACKGROUND: In this article, the test implementation of a school-oriented drug prevention program "Study without Drugs" is discussed. The aims of this study were to determine the results of the process evaluation and to determine whether the proposed school-oriented drug prevention program during a pilot project was effective for the participating pupils. METHODS: Sixty second-grade pupils at a junior high school in Paramaribo, Suriname participated in the test implementation. They were divided into two classes. For the process evaluation the students completed a structured questionnaire focusing on content and teaching method after every lesson. Lessons were qualified with a score from 0-10. The process was also evaluated by the teachers through structured interviews. Attention was paid to reach, dose delivered, dose received, fidelity, connection, achieved effects/observed behaviors, areas for improvement, and lesson strengths. The effect evaluation was conducted by using the General Liniair Model (repeated measure). The research (-design) was a pre-experimental design with pre-and post-test. RESULTS: No class or sex differences were detected among the pupils with regard to the assessment of content, methodology, and qualification of the lessons. Post-testing showed that participating pupils obtained an increased knowledge of drugs, their drug-resisting skills were enhanced, and behavior determinants (attitude, subjective norm, self-efficacy, and intention) became more negative towards drugs. CONCLUSIONS: From the results of the test implementation can be cautiously concluded that the program "Study without Drugs" may yield positive results when applied in schools). Thus, this pilot program can be considered a step towards the development and implementation of an evidence-based school-oriented program for pupils in Suriname.

Strategies to enhance knowledge of and adherence to dietary guidelines for management of hyperphosphatemia in hemodialysis patients have been studied extensively over the past decade. This review is the first to compile all of them (2003-2013) and conduct a meta-analysis through calculation of effect size, with the aim of identifying the optimal nutrition education methods for effective management of hyperphosphatemia in hemodialysis patients. The following strategies were identified as being effective in changing dietary behavior: 1) use of self-evaluation and self-regulation techniques within educational tools, along with easy-to-apply skills; 2) individualized counseling by a renal dietitian provided just before the hemodialysis session; 3) high-intensity education; and 4) long duration of interventions. Future studies should focus on conducting randomized controlled trials with powered samples to help generate stronger evidence.

BACKGROUND: The ecological perspective holds that human behavior depends on the interaction of different environmental factors and personal characteristics, but it lacks validation and operationalization. In the current paper, an ecological view was adopted to examine the interactive impact of several ecological systems on children's dietary intake and physical activity at childcare or similar facilities. The ecological view was operationalized into three types of interaction: 1) interaction between types of childcare environment (physical, social, political, economic); 2) interaction between micro-systems (the childcare and home environment) in meso-systems; and 3) interaction between childcare environment and child characteristics. The predictive value of each of these interactions was tested based on a systematic review of the literature. DISCUSSION: Several studies support the hypothesis that the influence of the childcare environment on children's physical activity and diet is moderated by child characteristics (age, gender), but interaction between environmental types as well as between micro-systems is hardly examined in the field of behavioral nutrition and physical activity. Qualitative studies and general child development research provide some valuable insights, but we advocate quantitative research adopting an ecological perspective on environmental influences. SUMMARY: Empirical studies operationalizing a true ecological view on diet and physical activity are scarce. Theorizing and assessment of interaction is advocated to become common practice rather than an exception in behavioral nutrition and physical activity research, in order to move the field forward.

Research on parenting practices has focused on individual behaviors while largely failing to consider the context of their use, i.e., general parenting. We examined the extent to which food parenting practices predict children's dietary behavior (classified as unhealthy: snacking, sugar-sweetened beverage; and healthy: water and fruit intake). Furthermore, we tested the moderating role of general parenting on this relationship. Within the KOALA Birth Cohort Study, in the Netherlands, questionnaire data were collected at 6 and 8 years (N = 1654). Correlations were computed to assess the association between food parenting practices and general parenting (i.e., nurturance, behavioral control, structure, coercive control, and overprotection). Linear regression models were fitted to assess whether food parenting practices predict dietary behavior. Instrumental and emotional feeding, and pressure to eat were found to have associations with undesirable child dietary behavior (increased unhealthy intake/decreased healthy intake), whereas associations were in the desirable direction for covert control, encouragement and restriction. Moderation analyses were performed by evaluating interactions with general parenting. The associations of encouragement and covert control with desirable child dietary behaviors were found to be stronger for children who were reared in a positive parenting context. Future research should assess the influence of contextual parenting factors moderating the relationships between food parenting and child dietary behavior as the basis for the development of more effective family-based interventions.
