Recent research in urban planning and public health has drawn attention to the associations between urban form and physical activity in adults. Because little is known on the urban-rural differences in physical activity, the main aims of the present study were to examine differences in physical activity between urban and rural adults and to investigate the moderating effects of the physical environment on the relationship between psychosocial factors and physical activity. In Flanders, Belgium, five rural and five urban neighborhoods were selected. A sample of 350 adults (20-65 years of age; 35 adults per neighborhood) participated in the study. Participants wore a pedometer for 7 days, and self-reported physical activity and psychosocial data were also collected. Results showed that urban adults took more steps/day and reported more walking and cycling for transport in the neighborhood, more recreational walking in the neighborhood, and more walking for transportation outside the neighborhood than rural adults. Rural adults reported more recreational cycling in the neighborhoods. The physical environment was a significant moderator of the associations between several psychosocial factors (modeling from family, self-efficacy, and perceived barriers) and physical activity. In rural participants, adults with psychosocial scores above average were more physically active, whereas there were no differences in physical activity according to psychosocial factors in urban participants. These results are promising and plead for the development of multidimensional interventions, targeting specific population subgroups. In rural environments, where changing the environment would be a very challenging task, interventions focusing on modifiable psychosocial constructs could possibly be effective.

“…Some previous studies that aimed to find equivalences between the "30 minutes" and the "10000 steps" messages have found increment estimations around 3100 and 4000 steps (13,14) . In the present study, the definition of the target increment in the number of steps was based on a classification suggested by Tudor-Locke and colleagues for a moderate intensity activity (13) .…”

“…Concerning to the use of pedometer, one limitation is the impossibility to measure activities that do not involve vertical displacement of the hip, such as those carried out by the upper members, and the possibility of misreporting of steps data. As to the precision level of data recording, the pedometer used in this study is considered as a tool with adequate accuracy in evaluating accumulated daily steps (14) . Furthermore, none of the volunteers practiced any other previous PA on a systematic fashion.…”

“…Based on the recommendation that every healthy adult should accumulate at least 30 minutes of moderate-intensity PA per day (1) , different quantification tools, such as pedometers and questionnaires, have been employed to evaluate PA patterns (10,11) . Recent studies have investigated the pedometer-measured amount of steps necessary for good health or for the "30-minute message" equivalence (12)(13)(14) . The proposed target of 10,000 steps per day (15,16) may represent an unattainable task for some sedentary people.…”

“…In parallel, studies involving subjects with some chronic diseases, such as diabetes, hypertension and obesity, have focused on physiological issues associated with an enhancement of the physical activity level (6,(16)(17)(18) . Despite some recent advances (12)(13)(14)(15) , the accumulated daily steps strategy still deserves better characterization regarding the amount of steps, duration, intensity and associated physiological effects.…”

Short AbstrActThe 10000 steps/day message has been proposed as a minimum steps/day target for healthy adults. Nevertheless, this target does not seem feasible as an initial goal for inactive adults. New strategies to progressively increase daily steps should be evaluated. The study evaluated the effectiveness of increase a pedometer-measured 3500 steps/day on physical performance at anaerobic threshold (AT). Nineteen healthy insufficiently active men, 19-46 yrs, wore a pedometer for 2 weeks to quantify their habitual daily steps at baseline. Afterwards, subjects were instructed to increase 3500 steps/day above baseline during 3 weeks (intervention). Cardiopulmonary exercise stress tests (CPX) were performed before and after the intervention. Submaximal exercise tolerance was analyzed by the heart rate at AT (HR-AT), the oxygen uptake at AT (VO2-AT), the time spent on CPX until AT onset and the reached distance. Nonparametric statistics were applied, expressing the results as median and minimum and maximum values. The variables were pair-wised compared by the Wilcoxon test. The differences were considered statistically significant when a two-tailed P-value was less than 5%. At baseline, median (min-max) of daily steps was 7295 (4700-14752 steps), whereas it was 11772 (8998-18620 steps) after the intervention (p=0.0001). On CPX, time until AT onset was higher after (359s; 179-521s) than before daily steps improvement (340s; 208-436s) (p=0.027). Similarly, the distance attained at AT was higher after (398.6m; 165.6-637.5m) than before the intervention (372.2m; 197.8-528.8m) (p=0.014). The increment of 3500 steps/day above baseline, during three weeks, was effective for improving exercise tolerance at AT. KeywordsWalking; Pedometer; Physical activity; Inactivity; Health promotion. (398.6m; 165.6-637.5m), comparativamente a antes da intervenção (372.2m; 197.8-528.8m) (p=0.014). O incremento de 3500 passos por dia acima do padrão habitual, durante três semanas, foi eficaz para aumentar a tolerância ao exercício no LA. resumo A mensagem dos 10000 passos diários tem sido proposta como meta mínima de passos para adultos saudáveis. Entretanto, esta meta parece não ser factível como objetivo inicial para homens inativos. Novas estratégias de aumento progressivo nos passos diários devem ser avaliadas. Este estudo avaliou a eficácia do incremento de 3500 passos por dia, medidos por pedômetro, no desempenho físico no limiar anaeróbi-co (LA). Dezenove homens saudáveis insuficientemente ativos, 19-46 anos, usaram um pedômetro por 2 semanas para quantificar o padrão habitual de passos diários. Em seguida, foram orientados a aumentarem 3500 passos/dia acima do padrão usual, durante 3 semanas (intervenção

Background: Many patients in primary care settings present with multiple behavioral risk factors for cardiovascular disease. Research has provided little information on the most effective ways to approach multiple behavior change counseling in clinical settings. Methods:We implemented a randomized trial in a publicly funded primary care setting to test whether a sequential presentation of stage of change-based counseling to stop smoking, reduce dietary sodium level to less than 100 mEq/L per day, and increase physical activity by at least 10 000 pedometer steps per week would be more effective than simultaneous counseling. African Americans with hypertension, aged 45 to 64 years, initially nonadherent to the 3 behavioral goals, were randomized to the following conditions: (1) 1 in-clinic counseling session on all 3 behaviors every 6 months, supplemented by motivational interviewing by telephone for 18 months; (2) a similar protocol that addressed a new behavior every 6 months; or (3) 1-time referral to existing group classes ("usual care"). The pri-mary end point was the proportion in each arm that met at least 2 behavioral criteria after 18 months.Results: A total of 289 individuals (67.3% female) were randomized, and 230 (79.6%) completed the study. At 18 months, only 6.5% in the simultaneous arm, 5.2% in the sequential arm, and 6.5% in the usual-care arm met the primary end point. However, results for single behavioral goals consistently favored the simultaneous group. At 6 months, 29.6% in the simultaneous, 16.5% in the sequential, and 13.4% in the usual-care arms had reached the urine sodium goal (P=.01). At 18 months, 20.3% in the simultaneous, 16.9% in the sequential, and 10.1% in the usualcare arms were urine cotinine negative (P=.08).Conclusions: Long-term multiple behavior change is difficult in primary care. This study provides strong evidence that addressing multiple behaviors sequentially is not superior to, and may be inferior to, a simultaneous approach.

The utility of the Digi-Walker step counter to assess daily physical activity patterns

Abstract: Pedometers provide a useful indicator of daily step counts but variability in activity patterns make it difficult to establish step count guidelines that correspond with other public health guidelines.
