RESUMO
BACKGROUND: The purpose of the study was to evaluate a 6-month intervention to promote office-employees' walking with pedometers and e-mail messages. METHODS: Participants were recruited by 10 occupational health care units (OHC) from 20 worksites with 2,230 employees. Voluntary and insufficiently physically active employees (N = 241) were randomized to a pedometer (STEP, N = 123) and a comparison group (COMP, N = 118). STEP included one group meeting, log-monitored pedometer-use and six e-mail messages from OHC. COMP participated in data collection. Reach, effectiveness, adoption, implementation, maintenance (RE-AIM) and costs were assessed with questionnaires (0, 2, 6, 12 months), process evaluation and interviews (12 months). RESULTS: The intervention reached 29% (N = 646) of employees in terms of participation willingness. Logistic regression showed that the proportion of walkers tended to increase more in STEP than in COMP at 2 months in "walking for transportation" (Odds ratio 2.12, 95%CI 0.94 to 4.81) and at 6 months in "walking for leisure" (1.86, 95%CI 0.94 to 3.69). Linear model revealed a modest increase in the mean duration of "walking stairs" at 2 and 6 months (Geometric mean ratio 1.26, 95%CI 0.98 to 1.61; 1.27, 0.98 to 1.64). Adoption and implementation succeeded as intended. At 12 months, some traces of the intervention were sustained in 15 worksites, and a slightly higher number of walkers in STEP in comparison with COMP was observed in "walking stairs" (OR 2.24, 95%CI 0.94 to 5.31) and in "walking for leisure" (2.07, 95%CI 0.99 to 4.34). The direct costs of the intervention were 43 Euros per participant. CONCLUSIONS: The findings indicate only modest impact on some indicators of walking. Future studies should invest in reaching the employees, minimizing attrition rate and using objective walking assessment. TRIAL REGISTERATION: ISRCTN79432107.

BACKGROUND: Low levels of physical activity (PA) and poor fitness tend to predict a decline in mobility. The current study investigated whether PA modifies the predictive value of health-related fitness (HRF) tests on difficulty in walking 2 km (WD). METHODS: PA was assessed by self-reported questionnaires in 1990 and 1996. Subjects age 55 to 69 years and free of self-reported WD participated in assessment of HRF in 1996. Occurrence of WD was assessed by questionnaire in 2002 (n=537). RESULTS: There were no statistically significant interactions between PA and HRF tests; thus, PA and HRF were both independent predictors of WD. Regardless of the PA level, the subjects in the poorest performing third in each HRF test had higher risk of WD than the subjects in the best performing third. CONCLUSIONS: PA and HRF seemed to be independent predictors of WD, although the association of PA with WD was weaker than the association of HRF. Thus, PA did not modify the predictive value of HRF on WD.

BACKGROUND: The purpose of the study is to examine the effects and feasibility of individual physical activity (PA) counseling in maternity and child health clinics in Finland. METHODS: Three clinics including both maternity and child health care signed up for the experimental (EXP) and three for the control group (CON). The participants were 132 pregnant and 92 postpartum primiparas. The nurses in EXP integrated a primary and four booster PA counseling sessions into routine visits. An option for supervised group exercise was offered. In CON former practices, usually including brief PA advice, were continued. Leisure-time PA (LTPA) prior to pregnancy was elicited by questionnaire and followed 16-18 and 36-37 weeks' gestation in maternity clinics and 5 and 10 months postpartum in child health clinics. Feasibility included safety, participant responsiveness, realization of counseling and applicability. RESULTS: According to analysis of covariance adjusted for baseline LTPA and possible confounders, no relative between-group differences in LTPA were found at the first follow-up in either maternity or child health clinics. At the last follow-up in maternity clinics the weekly number of at least moderate-intensity LTPA days was 43% (95% CI: 9, 87) higher and the weekly duration of at least moderate-intensity LTPA 154% (95% CI: 16, 455) higher in EXP compared with CON. Counseling proved feasible in both maternity and child health clinics. CONCLUSION: Counseling encouraged pregnant women to sustain their moderate-intensity LTPA and was feasible in routine practices. No effects were observed if counseling was initiated postpartum. TRIAL REGISTRATION: Current Controlled Trials ISRCTN21512277.

BACKGROUND: Postpartum weight retention may contribute to the development of obesity. We studied whether individual counselling on diet and physical activity from 2 to 10 months postpartum has positive effects on diet and leisure time physical activity and increases the proportion of primiparas returning to their pre-pregnancy weight. METHODS: A controlled trial including ninety-two postpartum primiparas was conducted in three intervention and three control child health clinics in primary health care in Finland. The intervention included individual counselling on diet and physical activity during five routine visits to a public health nurse; the controls received the usual care. RESULTS: In total, 50% of the intervention group and 30% of the control group returned to their pre-pregnancy weight (weight retention Assuntos

RESUMO
BACKGROUND AND AIMS: The functional independence of elderly populations deteriorates with age. Several tests of physical performance have been developed for screening elderly persons who are at risk of losing their functional independence. The purpose of the present study was to investigate whether several components of health-related fitness (HRF) are valid in predicting the occurrence of self-reported mobility difficulties (MD) among high-functioning older adults. METHODS: Subjects were community-dwelling men and women, born 1917-1941, who participated in the assessment of HRF [6.1-m (20-ft) walk, one-leg stand, backwards walk, trunk side-bending, dynamic back extension, one-leg squat, 1-km walk] and who were free of MD in 1996 (no difficulties in walking 2- km, n=788; no difficulties in climbing stairs, n=647). Postal questionnaires were used to assess the prevalence of MD in 1996 and the occurrence of new MD in 2002. Logistic regression analysis was used as the statistical method. RESULTS: Both inability to perform the backwards walk and a poorer result in it were associated with risk of walking difficulties in the logistic model, with all the statistically significant single test items included. Results of 1-km walk time and one-leg squat strength test were also associated with risk, although the squat was statistically significant only in two older birth cohorts. Regarding stair-climbing difficulties, poorer results in the 1-km walk, dynamic back extension and one-leg squat tests were associated with increased risk of MD. CONCLUSIONS: The backwards walk, one-leg squat, dynamic back extension and 1-km walk tests were the best predictors of MD. These tests are recommended for use in screening high-functioning older people at risk of MD, as well as to target physical activity counseling to those components of HRF that are important for functional independence.

OBJECTIVES: To examine the effectiveness of prescription-based counseling and self-monitoring in the promotion of physical activity in primary health care. METHODS: The study was conducted in Finland during 2003-2004. Physicians from 24 health care units (N = 67) were randomized to a prescription or a non-prescription group. The patients (N = 265) were assigned to the groups according to their physician. Every other patient of the non-prescription physicians received a pedometer and a physical activity log (MON) and feedback about their 5-day-recordings, the rest served as controls (CON). PA was assessed prior and 2 and 6 months after the physician's appointment with a questionnaire. RESULTS: The mean increase in weekly overall physical activity at 2 months was 1.0 (95% CI 0.0 to 2.0) session more in the prescription group than in controls. In at least moderate-intensity physical activity, the mean difference in changes was 0.8 (95% CI 0.1 to 1.5) sessions at 2 months and 0.9 (95% CI 0.2 to 1.5) sessions at 6 months for the favor of the prescription group. Compared to controls, self-monitoring increased the weekly duration of overall PA at 2 months on average by 217 min (95% CI 23 to 411). CONCLUSIONS: Prescription can be recommended as a tool for primary health care physicians to promote physical activity. Self-monitoring with an expert feedback can be useful in increasing especially the weekly duration of overall physical activity in the short term.

OBJECTIVE: To evaluate the feasibility and health-related content validity of 6 health-related fitness (HRF) and 3 functional performance (FP) tests among middle-aged and older persons. DESIGN: Cross-sectional methodologic study. SETTING: Field laboratories in 3 communities of northeast Finland. PARTICIPANTS: A regionally representative, community-based cohort of 55- to 79-year-old men (n=501) and women (n=632). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Health-related test exclusion rates (%) by age groups and odds ratios (ORs) of subjective health outcomes by fitness categories (least 20%, next 40%, most fit 40%). RESULTS: The health-related test exclusion rates increased with age, mainly because of musculoskeletal health limitations among the women and cardiovascular and musculoskeletal health limitations among the men. With the exception of dynamic back extension, 1-leg squat, 1-leg standing balance, and the 1-km walk among the women 75 years and older, 85% or more of the subjects qualified for the HRF tests and 95% or more for the FP tests. Strong and graded associations were found for cardiorespiratory and musculoskeletal fitness and the FP test levels with perceived health and functional ability status among both the men and the women (OR range, 2-31). The motor fitness test level was primarily associated with functional ability status. CONCLUSIONS: All the HRF and FP tests showed health-related content validity, and 4 of 6 of the HRF tests and all of the FP tests proved to be safe, with minor health-related test exclusions for middle-aged and older adults. The findings may help to target physical activity intervention toward persons at high risk for declining health and functional ability.
