We studied the contributions of parental fruit and vegetable (F&V) consumption, availability and accessibility of F&V in the home, exposure to F&V, and habit, in addition to psychosocial factors, in explaining F&V consumption in 4-12-year-old children. Furthermore, we looked for effect modification by ethnicity and gender. Children's parents (n = 1739)(More)
In a randomized, observer-blinded trial, the effectiveness of 3-month high-intensity training (HIT) of the isolated lumbar extensors was compared to low-intensity training (LIT). Eighty-one workers with nonspecific low back pain longer than 12 weeks were randomly assigned to either of the two training programs. Training sessions were performed on a modified(More)
OBJECTIVE To investigate the association between the child-care environment and physical activity of 2- and 3-year-olds. Based on an ecological view of environmental influences on health behavior, we hypothesized that the social and physical environment, as well as child characteristics (age and gender), would show independent and interactive effects on(More)
The European Smoking Prevention Framework Approach (ESFA) resulted in a smoking prevention project for six European countries. It included activities on four levels: adolescents, schools, parents and out-of-school activities. Common goals and objectives were developed, but countries were also able to include additional objectives. National diversities(More)
The European Smoking Prevention Framework Approach (ESFA) study in six countries tested the effects of a comprehensive smoking prevention approach after 24 (T3; N = 10,751) and 30 months (T4; N = 9,282). The programme targeted four levels, i.e. adolescents in schools, school policies, parents and the community. In Portugal, 12.4% of the T1 non-smokers in(More)
Interventions to promote physical activity are important in preventing children from becoming overweight. Many projects have been developed but only a few showed (moderate) effects. JUMP-in is a systematically developed primary-school-based intervention that focuses on the use of theory, environmental changes, parental influences and cooperation with(More)
Consumer researchers consider convenience orientation towards meal preparation to be a relevant construct for understanding consumer behavior towards foods. This study set out to conceptualize this construct and to develop a scale that measures it. As examined in two different samples of meal preparers, the resulting scale is reliable, satisfies a(More)
OBJECTIVE To examine whether smoking onset in young adolescents is predicted by peer or parental smoking. DESIGN Longitudinal design with one pretest and one follow-up at 12 months. SETTING Schools in Finland, Denmark, the Netherlands, the United Kingdom, Spain and Portugal. PARTICIPANTS 7102 randomly selected adolescents from six countries. Mean age(More)
BACKGROUND More knowledge is needed regarding the effectiveness of weight gain prevention programmes. The present study tested the 12-and 24-month effectiveness of the 'Netherlands Research programme weight Gain prevention' (NHF-NRG)-In Balance-project, a worksite-based intervention aimed at the prevention of weight gain. METHODS Twelve worksites (n = 553(More)
OBJECTIVE To measure the effects of two school-based interventions on children's intake of fruit and vegetables (F&V). DESIGN AND METHODS A total of six primary schools were randomly assigned to (1) a free F&V distribution programme, or (2) a multicomponent programme, consisting of a classroom curriculum and parental involvement. The two interventions(More)
