Factors associated with physical therapists' implementation of physical activity interventions in The Netherlands.

Background: Physical therapists play an important role in the promotion of physical activity (PA) and the effectiveness of PA interventions. However, little is known about the extent to which they implement PA interventions following the intervention protocol and about the factors influencing their implementation behaviors.

Objective: The study objective was to investigate physical therapists' implementation fidelity regarding PA interventions, including completeness and quality of delivery, and influencing factors with a Theoretical Domains Framework-based questionnaire.

Factors influencing primary health care professionals' physical activity promotion behaviors: a systematic review.

Background: Despite the promising findings related to the efficacy of interventions aimed at promoting physical activity (PA) in primary health care (PHC), the translation of these interventions to PHC practice does not always happen as desired.

Purpose: To help understand why efficacious PHC-based PA interventions are not effectively translated to practice, this study systematically reviewed the literature on factors influencing PHC professionals' PA promotion practices.

Method: Literature searches were conducted in Web of Science, PubMed, and PsycINFO for peer-reviewed articles published in English from 1990 onwards.

Factors influencing the introduction of physical activity interventions in primary health care: a qualitative study.

Background: The introduction of efficacious physical activity (PA) interventions in routine primary health care (PHC) is a complex process. Understanding factors influencing the process can enhance the development of successful introduction strategies.

Purpose: The aim of this qualitative study was to explore stakeholders' perceptions on factors influencing the introduction, i.

Measuring determinants of implementation behavior: psychometric properties of a questionnaire based on the theoretical domains framework.

Background: To be able to design effective strategies to improve healthcare professionals' implementation behaviors, a valid and reliable questionnaire is needed to assess potential implementation determinants. The present study describes the development of the Determinants of Implementation Behavior Questionnaire (DIBQ) and investigates the reliability and validity of this Theoretical Domains Framework (TDF)-based questionnaire.

Methods: The DIBQ was developed to measure the potential behavioral determinants of the 12-domain version of the TDF (Michie et al.

Dietary restraint and body mass change. A 3-year follow up study in a representative Dutch sample.

Objective: To determine in a representative Dutch sample the association of dietary restraint, Concern for Dieting, and Weight Fluctuation with subsequent change in body mass index (BMI; in kg/m(2)) in addition to possible moderator effects of sex, level of education, age category, ethnicity, overweight level and physical activity.

Design: In a longitudinal study in a representative Dutch sample consisting of 675 participants (331 females, 344 males), dietary restraint (including Concern for Dieting and Weight Fluctuation) was assessed with the Restraint Scale at baseline, and also self-reported weight and height. Three years later, weight and height were also assessed.

Combinations of techniques that effectively change health behavior: evidence from Meta-CART analysis.

Objective: Many health-promoting interventions combine multiple behavior change techniques (BCTs) to maximize effectiveness. Although, in theory, BCTs can amplify each other, the available meta-analyses have not been able to identify specific combinations of techniques that provide synergistic effects. This study overcomes some of the shortcomings in the current methodology by applying classification and regression trees (CART) to meta-analytic data in a special way, referred to as Meta-CART.

Do major life events influence physical activity among older adults: the Longitudinal Aging Study Amsterdam.

Background: Major life events are associated with a change in daily routine and could thus also affect habitual levels of physical activity. Major life events remain largely unexplored as determinants of older adults' participation in physical activity and sports. This study focused on two major life events, widowhood and retirement, and asked whether these major life events were associated with moderate to vigorous physical activity (MVPA) and sports participation.

Eating style, overeating and weight gain. A prospective 2-year follow-up study in a representative Dutch sample.

This study examined which individuals are particularly at risk for developing overweight and whether there are behavioral lifestyle factors that may attenuate this susceptibility. A prospective study with a 2-year follow-up was conducted in a sample representative of the general population of The Netherlands (n=590). Body mass change (self-reported) was assessed in relation to overeating and change in physical activity (both self-reported), dietary restraint, emotional eating, and external eating, as assessed by the Dutch Eating Behavior Questionnaire.

Long term follow-up of health-related quality of life in young adults born very preterm or with a very low birth weight.

Background: The purpose was, first, to evaluate changes in health-related quality of life (HRQL) in a cohort of very low birth weight (VLBW; <1500 g.) or very preterm (< 32 weeks of gestation) children between ages 14 and 19, and second, to identify correlates of HRQL at age 19.

Methods: HRQL was assessed using the Health Utilities Index Mark 3 (HUI3).

Changes in self-reported energy balance behaviours and body mass index during a mass media campaign.

Background: Prevention of (serious) overweight can be achieved by means of small behaviour changes in physical activity and/or diet.

Objective: To evaluate a mass media campaign promoting energy balance behaviours in a Dutch population. Effects were examined for body mass index (BMI) and five energy balance behaviours.

Determinants of physical activity and exercise in healthy older adults: a systematic review.

Background: The health benefits of regular physical activity and exercise have been widely acknowledged. Unfortunately, a decline in physical activity is observed in older adults. Knowledge of the determinants of physical activity (unstructured activity incorporated in daily life) and exercise (structured, planned and repetitive activities) is needed to effectively promote an active lifestyle.

Investigating the associations among overtime work, health behaviors, and health: a longitudinal study among full-time employees.

Background: It has often been suggested that high levels of overtime lead to adverse health outcomes. One mechanism that may account for this association is that working overtime leads to elevated levels of stress, which could affect worker's behavioral decisions or habits (such as smoking and lack of physical activity). In turn, this could lead to adverse health.

Eating style, overeating, and overweight in a representative Dutch sample. Does external eating play a role?

This study examined which individuals in particular are susceptible or resistant to develop overweight in our current obesogenic environment. A cross-sectional study was conducted in a sample of 1342 people representative of the general population in the Netherlands. Overweight-level (normal body weight> or =17.

Rates and determinants of repeated participation in a web-based behavior change program for healthy body weight and healthy lifestyle.

Background: In recent years, many tailored lifestyle counseling programs have become available through the Internet. Previous research into such programs has shown selective enrollment of relatively healthy people. However, because of the known dose-response relationship between the intensity and frequency of counseling and the behavior change outcomes, selective retention may also be a concern.

Web-based tailored lifestyle programs: exploration of the target group's interests and implications for practice.

An important challenge in Web-based health promotion is to increase the reach of the target audience by taking the target groups' desires into consideration. Data from 505 members of a Dutch Internet panel (representative for Dutch Internet users) were used to asses the target group's interests and needs. 28% participated in Web-based tailored lifestyle programs, 57% expressed an interest in such programs, and 15% expressed no interest.

GPs' assessment of patients' readiness to change diet, activity and smoking.

Background: The Stages of Change Model is increasingly used for lifestyle counselling. In general practice, the use of algorithms to measure stage of change is limited, but for successful counselling it is important to know patients' readiness to change.

Aim: To assess the accuracy of the assessment of patients' readiness to change fat consumption, physical activity, and smoking by GPs and general practice registrars.

Stage-matched nutrition guidance: stages of change and fat consumption in Dutch patients at elevated cardiovascular risk.

Objective: To assess the effects of stage-matched nutrition counseling on stages of change and fat intake.

Design: Controlled clinical trial.

Setting: 9 family practices in a family medicine practice network.

Lifestyle, nutritional status, health, and mortality in elderly people across Europe: a review of the longitudinal results of the SENECA study.

This article provides an overview of the longitudinal Survey in Europe on Nutrition and the Elderly: a Concerted Action (SENECA) study, which was designed to assess differences in dietary and lifestyle factors among elderly Europeans, and to identify the factors that contribute to healthy aging. Elderly people from Belgium, Denmark, France, Italy, Portugal, Spain, Switzerland, and The Netherlands participated in the SENECA study. Standardized measurements were conducted at baseline in 1988-1989 and were repeated in 1993 and 1999.

Web-based targeted nutrition counselling and social support for patients at increased cardiovascular risk in general practice: randomized controlled trial.

Background: Using the Internet may prove useful in providing nutrition counselling and social support for patients with chronic diseases.

Objective: We evaluated the impact of Web-based nutrition counselling and social support on social support measures, anthropometry, blood pressure, and serum cholesterol in patients at increased cardiovascular risk.

Methods: We conducted a randomized controlled trial among patients with increased cardiovascular risk in Canadian family practices.

Nutrition guidance in Dutch family practice: behavioral determinants of reduction of fat consumption.

Background: Studies have shown that the psychosocial determinants attitude, self-efficacy, subjective norm, and health threat are important in predicting intention to change fat consumption. However, the role of habit in relation to these determinants is still largely unknown.

Objective: We aimed to assess whether and how habit influences intention in relation to attitude, self-efficacy, subjective norm, and health threat.

Effects of a general practice-based intervention on diet, body mass index and blood lipids in patients at cardiovascular risk.

Background: General practice-based health-promotion programmes implemented by nurse-counsellors may reduce cardiovascular risk factors, particularly in patients at increased risk.

Design: In a randomized controlled trial, trained nurse-counsellors delivered cognitive behavioural programmes aiming to reduce cardiovascular risk in patients with hypertension, Type 2 diabetes mellitus or coronary heart disease. Of 591 eligible patients from seven general practices in Perth, Western Australia, 212 agreed to participate and were randomized to one of three groups.

Stage-matched nutrition guidance for patients at elevated risk for cardiovascular disease: a randomized intervention study in family practice.

Objective: To examine stage-matched nutrition counseling by family physicians and its effect on dietary intake, anthropometry, and serum lipid levels in patients at elevated risk for cardiovascular disease.

Methods: In this controlled trial, patients randomized to intervention practices received nutrition information following the Stages-of-Change Model, and patients randomized to control practices received usual care.

Results: At both 6 and 12 months after baseline, total fat intake and saturated fat intake declined significantly more in the intervention group than in the control group: -5.

Respiratory morbidity and lung function in two Aboriginal communities in Western Australia.

Objective: To examine differences in the rates of respiratory symptoms, asthma and levels of lung function in two remote Aboriginal communities.

Methodology: Respiratory symptoms, smoking history, skin prick test responses to common allergens, serum IgE, lung function, airway responsiveness to methacholine and white blood cell counts were compared in two Aboriginal communities, one from the central desert (n = 84) and another from the tropical north (n = 209) of Western Australia.

Results: Compared with the tropical community, chest tightness and dyspnoea were more frequent and forced expiratory volume in 1 s and forced vital capacity were lower in the desert community, despite similar levels of wheeze, doctor-diagnosed asthma and skin prick test responses and lower levels of airway responsiveness and smoking.
