Stability of and change in substance use risk personality: Gender differences and smoking cigarettes among early adolescents.

OBJECTIVE: Adolescents show a steadily increasing inclination toward health risk behaviors, including smoking cigarettes. There is ample evidence that personality traits are related to smoking behavior. However, less is known about the stability of and change in these personality traits during early adolescence and whether smoking behavior affects the developmental trajectories. Moreover, less is known about the influence of gender on the course of personality. METHOD: Longitudinal data of three waves were used from 1121 early adolescents. To measure personality, the Substance Use Risk Profile Scale was used. Individual growth curve models were conducted to measure the stability, mean-level change and individual differences in change for personality. RESULTS: Stability of personality was moderate for boys and ranged from moderate to high for girls. On average early adolescents became more impulsive and more sensation seeking over a period of 18 months. Furthermore, hopelessness for girls increased and the increase in sensation seeking was higher for girls than for boys. Third, smoking behavior was related to all personality traits, indicating that smoking adolescents are more anxious, hopeless, impulsive and sensation seeking than non-smoking adolescents. CONCLUSIONS: Our results are in line with the disruption hypothesis, i.e., during early adolescence there is a dip in personality maturity. There are clear differences between girls and boys in stability of and change in personality traits. Besides, although smoking behavior is related to personality, the change in personality is probably related to other variables.

Results of outdoor smoking bans at secondary schools on adolescents smoking behaviour: a quasi-experimental study.

BACKGROUND: Research on the effectiveness of school smoking policies on adolescents' smoking behaviour remain inconclusive. This study evaluates the results of an outdoor school ground smoking ban at secondary schools on adolescents smoking behaviour, taking individual characteristics into account. METHODS: Data on 2684 adolescents from 18 Dutch secondary schools (nine with and nine without an outdoor smoking ban) were obtained at two moments. Associations between outdoor school ground smoking bans, individual characteristics, and smoking prevalence and frequency were measured. Multilevel logistic regression analyses were used. At schools with a ban implementation fidelity was checked. RESULTS: Although smoking prevalence and frequency appeared to make a slower increase at schools with an outdoor smoking ban compared with schools without an outdoor smoking ban, the differences were not significant. Differences between schools in the prevalence of smoking behaviour of students could mainly be explained by individual characteristics. Smoking prevalence and frequency were higher among adolescents with a positive attitude towards smoking and when significant others were more positive about smoking. Smoking prevalence and frequency were significantly lower when adolescents perceived it as easy not to smoke. Implementation fidelity was good at schools with a ban. CONCLUSIONS: No short-term effects were found of an outdoor smoking ban. A longer follow-up time than 6 months is needed. In addition, future research should investigate effectiveness in relation to the enforcement of the ban, comprehensiveness of the ban and when it is prohibited to leave school grounds, as smoking behavior might be transferred off school grounds.

Learning from games: stakeholders' experiences involved in local health policy.

Since public health problems are complex and the related policies need to address a wide range of sectors, cross-sectoral collaboration is beneficial. One intervention focusing on stimulating collaboration is a 'policy game'. The focus on specific problems facilitates relationships between the stakeholders and stimulates cross-sectoral policymaking. The present study explores stakeholders' learning experiences with respect to the collaboration process in public health policymaking. This was achieved via their game participation, carried out in real-life stakeholder networks in the Netherlands, Denmark and Romania. The policy game (In2Action) was developed and implemented as a 1-day role-play. The data consisted of: (i) observations and evaluation notes during the game and (ii) participant questionnaire after the game. All three countries showed similar results in learning experience during the collaboration processes in local policymaking. Specific learning experiences were related to: (i) the stakeholder network, (ii) interaction and (iii) relationships. The game also increased participant's understanding of group dynamics and need for a coordinator in policymaking. This exploratory study shows that the game provides participants with learning experiences during the collaboration process in policymaking. Experiencing what is needed to establish cross-sectoral collaboration is a first step towards enhancing knowledge exchange and more effective public health policies.

Sustainability of outdoor school ground smoking bans at secondary schools: a mixed-method study.

Background: Although increasing numbers of countries are implementing outdoor school ground smoking bans at secondary schools, less attention is paid to the post-implementation period even though sustainability of a policy is essential for long-term effectiveness. Therefore, this study assesses the level of sustainability and examines perceived barriers/facilitators related to the sustainability of an outdoor school ground smoking ban at secondary schools. Methods: A mixed-method design was used with a sequential explanatory approach. In phase I, 438 online surveys were conducted and in phase II, 15 semi-structured interviews were obtained from directors of relevant schools. ANOVA (phase I) and a thematic approach (phase II) were used to analyze data. Results: Level of sustainability of an outdoor school ground smoking ban was high at the 48% Dutch schools with an outdoor smoking ban. Furthermore, school size was significantly associated with sustainability. The perceived barriers/facilitators fell into three categories: (i) smoking ban implementation factors (side-effects, enforcement, communication, guidelines and collaboration), (ii) school factors (physical environment, school culture, education type and school policy) and (iii) community environment factors (legislation and social environment). Conclusions: Internationally, the spread of outdoor school ground smoking bans could be further promoted. Once implemented, the ban has become 'normal' practice and investments tend to endure. Moreover, involvement of all staff is important for sustainability as they function as role models, have an interrelationship with students, and share responsibility for enforcement. These findings are promising for the sustainability of future tobacco control initiatives to further protect against the morbidity/mortality associated with smoking.

Developing a policy game intervention to enhance collaboration in public health policymaking in three European countries.

BACKGROUND: One of the key elements to enhance the uptake of evidence in public health policies is stimulating cross-sector collaboration. An intervention stimulating collaboration is a policy game. The aim of this study was to describe the design and methods of the development process of the policy game 'In2Action' within a real-life setting of public health policymaking networks in the Netherlands, Denmark and Romania. METHODS: The development of the policy game intervention consisted of three phases, pre intervention, designing the game intervention and tailoring the intervention. RESULTS: In2Action was developed as a role-play game of one day, with main focus to develop in collaboration a cross-sector implementation plan based on the approved strategic local public health policy. CONCLUSIONS: This study introduced an innovative intervention for public health policymaking. It described the design and development of the generic frame of the In2Action game focusing on enhancing collaboration in local public health policymaking networks. By keeping the game generic, it became suitable for each of the three country cases with only minor changes. The generic frame of the game is expected to be generalizable for other European countries to stimulate interaction and collaboration in the policy process.

Schools as smoke-free zones? Barriers and facilitators to the adoption of outdoor school ground smoking bans at secondary schools.

BACKGROUND: Whereas smoking bans inside secondary school buildings are relatively widespread, a smoking ban for the outdoor school grounds is less common. Therefore, this study investigates why many secondary schools fail to adopt an outdoor school ground smoking ban. The aim is to elucidate the perceived barriers and facilitators of stakeholders at schools without an outdoor school ground smoking ban. METHODS: Qualitative data were obtained from 60 respondents of 15 secondary schools. Semi-structured interviews were held with various key stakeholders and a thematic approach was used for analysis of the transcripts. RESULTS: The perceived barriers and facilitators of the stakeholders fell into four categories: 1) socio-political characteristics (legislation and social norm), 2) school characteristics (policy, decision process, enforcement, resources, workforce conditions, communication and collaboration), 3) individual characteristics (support, knowledge, and target group), and 4) smoking ban characteristics (environmental factors, guideline recommendations, outcome expectations, and evidence). CONCLUSIONS: These findings highlight the importance of legislation for outdoor smoking bans. Moreover, collaboration, communication and involving stakeholders during an early stage of the process should be stimulated, as this might increase adoption. These results can be applied in future studies on outdoor tobacco control policies; moreover, they may facilitate tobacco control initiatives leading to more smoke-free environments to further protect youth from the harmful effects of tobacco.

Do practice characteristics explain differences in morbidity estimates between electronic health record based general practice registration networks?

BACKGROUND: General practice based registration networks (GPRNs) provide information on population health derived from electronic health records (EHR). Morbidity estimates from different GPRNs reveal considerable, unexplained differences. Previous research showed that population characteristics could not explain this variation. In this study we investigate the influence of practice characteristics on the variation in incidence and prevalence figures between general practices and between GPRNs. METHODS: We analyzed the influence of eight practice characteristics, such as type of practice, percentage female general practitioners, and employment of a practice nurse, on the variation in morbidity estimates of twelve diseases between six Dutch GPRNs. We used multilevel logistic regression analysis and expressed the variation between practices and GPRNs in median odds ratios (MOR). Furthermore, we analyzed the influence of type of EHR software package and province within one large national GPRN. RESULTS: Hardly any practice characteristic showed an effect on morbidity estimates. Adjusting for the practice characteristics did also not alter the variation between practices or between GPRNs, as MORs remained stable. The EHR software package 'Medicom' and the province 'Groningen' showed significant effects on the prevalence figures of several diseases, but this hardly diminished the variation between practices. CONCLUSION: Practice characteristics do not explain the differences in morbidity estimates between GPRNs.

Concept mapping as a promising method to bring practice into science.

OBJECTIVE: Concept mapping is a method for developing a conceptual framework of a complex topic for use as a guide to evaluation or planning. In concept mapping, thoughts and ideas are represented in the form of a picture or map, the content of which is determined by a group of stakeholders. This study aimed to explore the suitability of this method as a tool to integrate practical knowledge with scientific knowledge in order to improve theory development as a sound basis for practical decision-making. METHOD: Following a short introduction to the method of concept mapping, five Dutch studies, serving different purposes and fields in public health, will be described. The aim of these studies was: to construct a theoretical framework for good regional public health reporting; to design an implementation strategy for a guideline for integral local health policy; to guide the evaluation of a local integral approach of overweight and obesity in youth; to guide the construction of a questionnaire to measure the quality of postdisaster psychosocial care; and to conceptualize an integral base for formulation of ambitions and targets for the new youth healthcare programme of a regional health service. RESULTS: The studies showed that concept mapping is a way to integrate practical and scientific knowledge with careful selection of participants that represent the different perspectives. Theory development can be improved through concept mapping; not by formulating new theories, but by highlighting the key issues and defining perceived relationships between topics. In four of the five studies, the resulting concept map was received as a sound basis for practical decision-making. CONCLUSIONS: Concept mapping is a valuable method for evidence-based public health policy, and a powerful instrument for facilitating dialogue, coherence and collaboration between researchers, practitioners, policy makers and the public. Development of public health theory was realized by a step-by-step approach, considering both scientific and practical knowledge. However, the external validity of the concept maps in place and time is of importance.

Migration and geographical inequalities in health in the Netherlands: an investigation of age patterns.

OBJECTIVES: This paper estimates, for six different age groups, whether and how migration influences inequalities in health between deprived and non-deprived neighbourhoods in the Netherlands. METHODS: Data were accessed from the Netherlands Housing Survey 2006. Using multi-level logistic regression analyses, we compared the health of migrants with that of nonmigrants in the area of origin and assessed the role of demographic and socioeconomic characteristics. Next, we assessed the magnitude of health differences between deprived versus non-deprived areas among migrants and non-migrants. RESULTS: For many age groups, migrants into non-deprived areas were healthier and migrants into deprived areas had similar levels of health compared with non-migrant populations in the area of origin. These differences in health were not explained by demographic and socio-economic characteristics. For all ages and for people aged 25-34 years we found smaller area inequalities in health among migrants compared with non-migrants. For most other age groups, about equally large differences were observed. CONCLUSIONS: For most age groups, the results do not provide empirical support to the expectation that migration would enlarge health differences between deprived and non-deprived neighbourhoods.

A lifestyle intervention to reduce Type 2 diabetes risk in Dutch primary care: 2.5-year results of a randomized controlled trial.

AIMS: To determine the effectiveness of a 2.5-year lifestyle intervention for Type 2 diabetes prevention in Dutch general practice compared with usual care. METHODS: A randomized controlled trial of 925 individuals at high risk for Type 2 diabetes (FINDRISC-score ≥ 13) in 14 general practices in the Netherlands. Intervention consisted of lifestyle counselling from the nurse practitioner and the general practitioner. Usual care consisted of oral and written information at the start of the study. Study groups were compared over 2.5 years regarding changes in clinical and lifestyle measures. RESULTS: Both groups showed modest changes in body weight, glucose concentrations, physical activity and dietary intake [weight: intervention group, -0.8 (5.1) kg, usual care group, -0.4 (4.7) kg, (P=0.69); fasting plasma glucose: intervention group, -0.17 (0.4) mmol/l, usual care group, -0.10 (0.5) mmol/l, (P=0.10)]. Differences between groups were significant only for total physical activity and fibre intake. In the intervention group, self-efficacy was significantly higher in individuals successful at losing weight compared with unsuccessful individuals. No significant differences in participant weight loss were found between general practitioners and nurse practitioners with different levels of motivation or self-efficacy. CONCLUSIONS: Diabetes risk factors could significantly be reduced by lifestyle counselling in Dutch primary care. However, intervention effects above the effects attributable to usual care were modest. Higher participant self-efficacy seemed to facilitate weight loss. Lack of motivation or self-efficacy of professionals did not negatively influence participant guidance.

The development of an empirical model for regional public health reporting. A descriptive study in two Dutch pilot regions.

AIM: To develop and describe an empirical model for regional public health reporting, based on the model and experience of the Dutch national Public Health Status and Forecasts (PHSF) as well as on relevant theories and literature. METHODS: Three basic requirements were chosen in a preparatory feasibility study: the products to be developed, the project organization of the pilot study, and a regional elaboration of the conceptual model of the national PHSF. Subsequently, from November 2005 to June 2007, a regional PHSF was developed in two Dutch pilot regions, to serve as a base for the empirical model for regional public health reporting. RESULTS: The developed empirical regional PHSF model consists of different products for different purposes and target groups. Regional and Municipal Reports aim to underpin strategic regional and local public health policy. Websites contain up-to-date information, aiming to underpin tactical regional and local public health policy by providing building blocks for translating strategic policy priorities into concrete plans of action. Numerous stakeholders are involved in the development of a regional PHSF. The developed empirical process model for a regional PHSF connects to the theoretical framework in which interaction between researchers and policymakers is an important condition for the use of research data in public health policy. CONCLUSIONS: The empirical model for a regional PHSF can be characterized by its 1) products, 2) content and design, and 3) underlying process and organization. This empirical model can be seen as a first step in the direction of a generic model for regional public health reporting.

An active strategy to identify individuals eligible for type 2 diabetes prevention by lifestyle intervention in Dutch primary care: the APHRODITE study.

BACKGROUND: Several trials have shown the potential of lifestyle intervention programmes for prevention of type 2 diabetes. The effectiveness of implementation of these programmes into daily practice is now being studied in several countries. The 'Active Prevention in High Risk individuals of Diabetes Type 2 in Eindhoven' (APHRODITE) study investigates whether type 2 diabetes prevention by lifestyle intervention is effective in Dutch primary care. In this article we describe the process of recruiting the study participants. OBJECTIVE: To assess the reach of an active strategy to recruit participants for a programme on type 2 diabetes prevention by lifestyle intervention in Dutch primary care. METHODS: A diabetes risk questionnaire was sent to general practice patients aged 40-70 years. Individuals with a risk score above threshold were invited for an admission interview with the GP and an oral glucose tolerance test (OGTT). All individuals with non-diabetic glucose levels were asked to participate in the intervention study. RESULTS: In total, 8752 (54.6%) of the individuals returned the questionnaire in time. Of all high-risk individuals (n = 1533), 73.1% contacted their practice to schedule a consultation with the GP. Response rates varied significantly among practices. CONCLUSIONS: Using invitational letters, a substantial amount of individuals could be motivated to participate in a programme on type 2 diabetes prevention by lifestyle intervention in Dutch primary care. Further research is needed on what kind of strategy would be most effective and efficient to screen for individuals at high risk for type 2 diabetes in primary care.

Health status and the challenges for prevention in The Netherlands.

In 2002, the third Public Health Status and Forecasts report was published, containing up-to-date information about Dutch public health and health care. A striking finding was that although life expectancy (LE) in The Netherlands increased between 1980 and 2000, the LE of men is rising less rapidly than the European Union (EU) average. The LE of Dutch women is stagnating and has now fallen below the EU average. These and many other unfavourable trends in the health status of the Dutch population were found to be largely due to unhealthy behaviour. One of the policy recommendations therefore was to strengthen the investments in prevention in order to reverse the stagnation in health status. In response to the findings, the Ministry of Health, Welfare and Sport published the National Prevention Paper. This Paper states that the Ministry, within the existing prevention policy, will pay more attention to healthy behaviour, stressing the responsibility of citizens as well as the societal responsibility of other parties, such as business communities, schools, health insurers and care suppliers. The prevention of specific diseases (diabetes, psychosocial problems, heart diseases, cancer, musculosceletal disorders, asthma and chronic obstructive pulmonary disease) has been given priority status. In this article, we present the major findings regarding the health status of the Dutch population and discuss the implications for prevention policy.
