“…The lack of moderation of personal characteristics confirms the results of a recent study by Lorentzen et al, who found that none of their measured personal characteristics (i.e., gender, age, ethnicity, education, or BMI) moderated the effect of a 3-year community-based intervention on PA behavior among the general adult population [49]. However, the lack of moderation of health-related characteristics (i.e., functional limitations and baseline PA level) do not confirm the findings of the study of Wilcox et al who found that their two interventions were more efficient among participants less active at baseline [36].…”

Background Important health benefits can be derived when low-cost (e.g., computer-tailored) physical activity interventions for older adults demonstrate sustained effects. Purpose The purpose of the study was to conduct in-depth analysis on the long-term efficacy of two tailored physical activity interventions for older adults. Methods A randomized controlled trial (n=1,971) with two computer-tailored interventions and a no-intervention control group was conducted. The two tailored interventions consisted of three tailored letters, delivered during 4 months. The basic tailored intervention targeted psychosocial determinants alone, while the environmentally tailored intervention additionally targeted environmental determinants, by providing tailored environmental information. Selfreported behaviors (i.e., total physical activity, transport walking and cycling, leisure walking and cycling, and sports) were measured at baseline and 12 months. Additionally, potential personal, health-related, and psychosocial moderators of the intervention effects were examined. Results The environmentally tailored intervention was effective in changing total physical activity, leisure cycling, and sports compared with the basic intervention and control group. No intervention effects were found for the basic intervention. Moderation analysis revealed that participants with a higher age, lower body mass index, and higher intention were unresponsive to the interventions. Conclusions Providing environmental information is an effective intervention strategy for increasing physical activity behaviors among older adults, especially among certain "at-risk" subgroups such as lower educated, overweight, or insufficiently active participants. Moderation analysis was perceived as a promising method for identifying meaningful subgroups that are unaffected by an intervention, which should receive special attention in future interventions.

Targeting physical activity in a low socioeconomic status population: observations from the Norwegian “Romsås in Motion” study

Objective: To summarize the main results of a community-based study on physical activity promotion -"Romsås in Motion". Methods:We assessed changes in physical activity, body mass and psychosocial mediators of physical activity from a pseudo-experimental cohort study involving two districts with low socio-economic status in Oslo, Norway. In 2000, baseline investigation included 2,950 30-67 year olds -48% of those invited. At follow-up in 2003 we measured 1,776 subjects (67% of those eligible). A set of theoretically informed strategies targeting individuals, groups and the environment were implemented, tailored towards groups with different psychosocial readiness for change. We report net changes (the difference between changes in the intervention and control districts) and results of mediation analyses related to the effect of the intervention. Results:The increase in physical activity measured by two questionnaires was 9.5% (p=0.008) and 8.1% (p=0.02), respectively. The proportion who increased their body mass was reduced by 50% compared with the control district. Participation in walking and aerobic exercise groups, having seen the "Walk the stairs"-poster and used the walk path were particularly effective intervention components. The most promising psychosocial mediators of forward transition in stages of change were physical activity identity, perceived control, support from friends and family, and self-efficacy when facing psychological barriers. Conclusion:Through a theoretically informed, low-cost, population-based intervention program we observed an increase in physical activity levels and a reduced weight gain.Mediation findings regarding forward transition in stages of change enhance our understanding of psychosocial mechanisms of behaviour change, and may prove helpful in guiding implementation and evaluation of future interventions. 3In western societies today low socio-economic status (SES) at the individual, group and regional level represents a risk factor for premature cardiovascular disease (CVD), 1-2 a sedentary lifestyle and is linked to the world-wide increase in obesity and type 2 diabetes. [3][4][5] Although lifestyle interventions may be highly effective in high risk individuals, [6][7] very few community-based interventions have addressed behavioural risk factors for type 2 diabetes, and most study designs are flawed. 8 Even small improvements in one or more risk factors, if achieved in a large proportion of the population, 9 can provide considerable impact on public health. Thus, such interventions are needed, especially in low-income communities. 8 The determinants of physical activity behaviour are multi-factorial. 10-17The most promising theories and models hypothesize that behaviour change is mediated by change in proximal psychological factors such as attitudes, efficacy, control beliefs and identity.Further, influencing also more distal social and physical environmental factors comprising family support and social networks, organizations, communities and societies to reinf...

“…It might be that cultural attitudes and values held by the south Asian immigrants do not encourage participation in PA, although our results indicate that the participants hold strong positive attitudes towards physical activity. Identifying oneself as a physically active individual, believing in one's ability to perform physical activity, and receiving support for being physically active have repeatedly, in a number of cultural settings, been found to correlate with or mediate physical activity participation (38)(39)(40). The modest scores on these variables in the present sample may contribute in the explanation of the low level of PA.…”

Background:The level of physical fitness in south Asian immigrants living in Norway is largely unknown, but the level of physical activity seems to be low, possibly in part explaining their high prevalence of diabetes and cardiovascular diseases. However, previous studies have used self-reported measures of physical activity, and it might be questioned whether the previous data reflect the true physical activity level. Aim: To describe objectively measured physical activity level, cardiorespiratory fitness and diabetes risk in a group of Pakistani immigrant men living in Oslo, Norway. Methods: One hundred and fifty Pakistani immigrant men in the age group 25-60 years were included. Physical activity level was assessed with an accelerometer. Cardiorespiratory fitness was measured until exhaustion on a treadmill, and diabetes risk was evaluated with an oral glucose tolerance test. Results: Mean age was 37.3 years (SD=7.7). Total physical activity level was 308 counts/min (SD=131), and peak oxygen uptake was 34.2 ml·kg -1 ·min -1 (SD=5.6). Fifty percent of the participants had the metabolic syndrome, and 76% were obese. Physical activity level and cardiorespiratory fitness level were lower, and prevalence of the metabolic syndrome higher in a subgroup of taxi drivers as compared with those in other occupations (P<0.05). Conclusions: Physical activity and cardiorespiratory fitness levels are low and diabetes risk high among Pakistani immigrant men living in Oslo, especially in taxi drivers.
