[Exercise-based cardiac rehabilitation is associated with reduced risk of myocardial infarction]

In patients with coronary artery disease, exercise-based cardiac rehabilitation (EBCR) is recommended to decrease all-cause and cardiovascular mortality, hospitalisation and risk of myocardial infarction and to improve aerobic capacity and muscle strength and endurance. Before starting the EBCR program, a pre-exercise screening is conducted. Exercise is individually prescribed based on tests of aerobic and muscular strength/endurance, as part of a comprehensive and medically supervised program. A post-exercise assessment is performed to evaluate the effects of exercise and to provide an exercise prescription to encourage life-long exercise.

Physical capability, physical activity, and their association with femoral bone mineral density in adults aged 40 years and older: The Tromsø study 2015-2016

Since muscles can influence bone growth and vice versa, we examined if level of physical activity and physical capability tests can predict areal bone mineral density (aBMD). Both high activity level and good test performance were associated with higher aBMD, especially in women.

INTRODUCTION

Muscle influences bone formation and vice versa. Tests of physical capability and level of physical activity reflect various muscle qualities. We assessed the associations between total hip aBMD and physical activity as well as a range of standardized physical capability tests in an adult general population.

METHODS

A total of 3 533 women and men aged 40-84 years, participating in the population-based cross-sectional Tromsø study in Norway in 2015-2016, were included. Linear regression was used to assess associations between aBMD and physical activity and the physical capability tests grip strength, Timed Up and Go (TUG), Short Physical Performance Battery (SPPB), and standing balance. Non-linear associations were examined in cubic spline models. Standardized regression coefficients were calculated to compare effect sizes across physical capability measures.

RESULTS

In fully adjusted models, higher physical activity was positively associated with total hip aBMD in both sexes compared to a sedentary lifestyle. All tests of physical capability were associated with aBMD in women, SPPB showing the strongest association although effect sizes were too small to indicate clinically significant differences (1 point increase corresponded to an aBMD increase of 0.009 g/cm², CI = 0.005 to 0.012). In men, SPPB and its subtests were associated with aBMD with chair rises showing the strongest association (1 s increase in execution time corresponded to an aBMD decrease of 0.005 g/cm², CI = 0.008 to 0.002).

CONCLUSION

Physical activity was associated with aBMD, and tests of physical capability can account for some of the aBMD variations in adults aged 40 years and older, especially in women.

Access to, use, knowledge, and preferences for information technology and technical equipment among people with chronic obstructive pulmonary disease (COPD) in Sweden. A cross-sectional survey study

BACKGROUND

The use of information technology can make pulmonary rehabilitation interventions in people with chronic obstructive pulmonary disease (COPD) more flexible and thereby has the potential to reach a larger proportion of the population. However, the success of using information technology in pulmonary rehabilitation is dependent on the end-user's competence in information technology and access to the Internet. The aim was to describe the access to, and the use, knowledge, and preferences of information technology and technical equipment among people with COPD.

METHODS

Telephone interviews were conducted using a standardised questionnaire on information technology and technical devises addressing the household, access to and usage of the Internet, contact with authorities, e-commerce, security, the workplace, digital competence, and disabilities. Questions were also posed regarding participants' views on a future eHealth tool for COPD, appropriate content, and the potential likelihood for them to use an eHealth tool for exercise training.

RESULTS

In total 137 persons agreed to participate, 17 dropped out resulting in 120 included participants (response rate 88%). The participants (86 women) were aged 51 to 92 years (mean: 72.5), and all severity grades of COPD according to GOLD A-D were represented. Over 90% had access to the Internet. Smartphones were used by 81%, and over 90% used apps. Participants had high knowledge of how to use the Internet, 91% had used the Internet during the last 3 months, 85% almost every day. The most common requests for a future eHealth tool for COPD were evidence-based and trustworthy information on COPD, (including medication, exercise training, inhalation and breathing techniques), communication (chat) with others and with health carers. Access to individually adjusted exercise training, and support, (motivation via prompts, chat rooms, digital information board) was also desired.

CONCLUSIONS

The present study showed that people with COPD in Sweden have high access and ability to use the Internet and information technology. They are frequent users and most of them take part in the digital society, even to a higher extent than the general population. The results show that the use of an eHealth tool could be a suitable strategy for people with COPD.

Mobilization Started Within 2 Hours After Abdominal Surgery Improves Peripheral and Arterial Oxygenation: A Single-Center Randomized Controlled Trial

OBJECTIVE

The aim of this study was to investigate if mobilization out of bed, within 2 hours after abdominal surgery, improved participants' respiratory function and whether breathing exercises had an additional positive effect.

METHODS

Participants were 214 consecutively recruited patients who underwent elective open or robot-assisted laparoscopic gynecological, urological, or endocrinological abdominal surgery with an anesthetic duration of >2 hours. They were recruited to a randomized controlled trial. Immediately after surgery, patients were randomly assigned to 1 of 3 groups: mobilization (to sit in a chair) and standardized breathing exercises (n = 73), mobilization (to sit in a chair) only (n = 76), or control (n = 65). The interventions started within 2 hours after arrival at the postoperative recovery unit and continued for a maximum of 6 hours. The primary outcomes were differences in peripheral oxygen saturation (SpO2, as a percentage) and arterial oxygen pressure (PaO2, measured in kilopascals) between the groups. Secondary outcomes were arterial carbon dioxide pressure, spirometry, respiratory insufficiency, pneumonia, and length of stay.

RESULTS

Based on intention-to-treat analysis (n = 214), patients who received mobilization and breathing exercises had significantly improved SpO2 (mean difference [MD] = 2.5%; 95% CI = 0.4 to 4.6) and PaO2 (MD = 1.40 kPa; 95% CI = 0.64 to 2.17) compared with the controls. For mobilization only, there was an increase in PaO2 (MD = 0.97 kPa; 95% CI = 0.20 to 1.74) compared with the controls. In the per-protocol analysis (n = 201), there were significant improvements in SpO2 and PaO2 for both groups receiving mobilization compared with the controls. Secondary outcome measures did not differ between groups.

CONCLUSION

Mobilization out of bed, with or without breathing exercises, within 2 hours after elective abdominal surgery improved SpO2 and PaO2.

IMPACT

The respiratory effect of mobilization (out of bed) immediately after surgery has not been thoroughly evaluated in the literature. This study shows that mobilization out of bed following elective abdominal surgery can improve SpO2 and PaO2.

LAY SUMMARY

Mobilization within 2 hours after elective abdominal surgery, with or without breathing exercises, can improve patients' respiratory function.

StayBalanced: implementation of evidence-based fall prevention balance training for older adults-cluster randomized controlled and hybrid type 3 trial

BACKGROUND

The StayBalanced programme has shown positive effects on fall prevention, balance control and fear of falling. Despite convincing evidence on the efficacy and effectiveness of balance training, there is a gap between research findings and what is provided in community-based and clinical health care settings. Therefore, transferring evidence-based balance training into clinical practice is needed.

METHODS

This project, designed as a hybrid type 3 trial, is a cluster-randomized study with a mixed-method design, carried out in primary health care settings. The aim is to investigate the effectiveness of two different strategies to facilitate the implementation of an intervention, the StayBalanced balance training programme, in primary health care, including evaluation of relative changes and maintenance in patient outcomes between intervention arms over 24 months. The StayBalanced programme will be launched through a website with information on the balance training and how to use it in clinical practice. One implementation strategy will include close facilitation, i.e. support and close follow-ups initiated by the researchers, in addition to access to the website. The other strategy simply includes access to the StayBalanced website. Outcome measures in the project consist of implementation outcomes, such as acceptability, feasibility, fidelity and sustainability of the StayBalanced programme. Outcomes at an individual level for older adults participating in the training will include fall-related concerns, health-related quality of life, balance performance, gait, physical activity, muscle strength in lower extremities, number of falls and compliance with training.

DISCUSSION

This study will generate new understanding of effective strategies for transferring research to clinical practice and thereby reduce an important knowledge gap, as well as aid decision-making for future implementation of evidence-based methods. Furthermore, it will contribute to improved balance and gait, increased level of physical activity and function, and improved health-related quality of life for the individuals participating in the programme.

"Stay balanced" - effectiveness of evidence-based balance training for older adults transferred into a physical therapy primary care setting - a pilot study

Purpose: To evaluate the effects of the Stay Balanced program when this is transferred into a clinical setting regarding balance, gait speed, leg muscle strength, concerns about falling, and physical activity.Method: Implementation pilot study with a pre-post intervention design. Fifteen older adults, 75-91 years of age, participated in a progressive balance training program with a focus on divided attention. The balance training was performed in group sessions twice a week for 10 weeks at a primary care physical therapy clinic. Training efficacy was evaluated after completion of training as well as after 3 months using the Mini-Balance Evaluation Systems Test (Mini-BESTest), 10-meter walk test, 30-s chair stand test, Fall Efficacy Scale-International (FES-I), and steps/day.Results: Significant improvements were shown at the 10-week follow up for balance, gait speed, leg muscle strength, and concerns about falling (p < 0.008). At the 3-month follow-up balance, leg muscle strength and concerns about falling showed persistent improvement compared to baseline (p < 0.045). No significant differences were found for physical activity.Conclusions: This study confirms the results of our previous randomized controlled trials (RCTs), and suggests that the Stay Balanced program can be transferred to clinical physiotherapy practice. The program was appreciated by the participants and proved to be safe, effective, and feasible in primary care.Implication for rehabilitationThe Stay Balance program can easily be transferred to clinical practice without losing the effectiveness of the intervention in older adults with balance problems.The program was appreciated by the participants and proved to be safe, effective, and feasible when executed in primary care.Stay Balance program is an individually adjusted and progressive group balance training including exercises with divided attention that can easily be transferred to tasks in daily life.

Osteoporosis and osteopenia in the distal forearm predict all-cause mortality independent of grip strength: 22-year follow-up in the population-based Tromsø Study

Low bone mineral density (BMD) gives an increased risk of fractures, which can lead to premature death. Can BMD of the wrist predict mortality? BMD consistent with osteopenia and osteoporosis gave a significantly increased risk of death for both men and women in a general population in Tromsø, Norway.

INTRODUCTION

To investigate if bone mineral density (BMD) levels of the distal forearm, consistent with osteopenia and osteoporosis, can predict mortality and if grip strength is an effect modifier.

METHODS

The study population constituted 6565 participants aged 50-79 years at baseline in the Tromsø Study wave 4 conducted in 1994-1995. Forearm BMD measured by SXA was categorized as "normal," "osteopenia," or "osteoporosis" following WHO's definition. Cox regression with all-cause mortality as the outcome over 22 years of follow-up was performed for men and women separately, adjusting for health-related factors, as well as BMD by grip strength interaction. A secondary analysis with a 15-year follow-up also adjusted for hip fractures and osteoporotic fractures.

RESULTS

During follow-up, 3176 of participants died (47%). Those categorized as osteoporotic had higher mortality hazard ratio (HR) compared to those with normal BMD; men HR = 1.37 (95% confidence interval (CI) 1.19, 1.58) and women HR = 1.32 (1.14, 1.53) were adjusted for age, body mass index, physical activity, smoking habits, education, health status, chronic diseases, and grip strength. Corresponding HRs for osteopenia were men HR = 1.13 (1.00, 1.27) and women HR = 1.17 (1.01, 1.35). Further adjustments for fractures did only marginally attenuate the results, and HRs were still significant. There was no grip strength by BMD interaction.

CONCLUSION

Men and women with low distal forearm BMD values, consistent with osteoporosis or osteopenia, had an increased mortality compared to normal BMD participants. High grip strength did not modify this association, and the association remained after adjustment for a range of health-related factors.

Short- and Long-Term Effects of Balance Training on Physical Activity in Older Adults With Osteoporosis: A Randomized Controlled Trial

Background and Purpose:

We have developed a 12-week balance training program for older adults shown to improve fall-related concerns, gait speed, balance performance, and physical function. We hypothesized that this balance training would also contribute to higher habitual physical activity (PA) levels and improved health-related quality of life (HRQoL). The primary aim was to evaluate short- and long-term effects of the balance training program on objectively measured habitual PA in older adults with osteoporosis. Secondary aims were to assess the effects of the balance training on HRQoL, and to study whether any effects on PA were associated with changes in HRQoL, gait speed, balance performance, fall-related concerns, and physical function.

Methods:

A randomized controlled trial with follow-up at 3, 9, and 15 months, including 91 participants with osteoporosis (75.6 ± 5.4 years), compared a balance training group (n = 61) with a control group (n = 30). The primary outcome was effect on habitual PA measured as steps/day, dichotomized into less than 5000 or 5000 or more steps/day. Physical activity was assessed with pedometers (Yamax) and accelerometers (Actigraph), HRQoL with the Short Form-36 (SF-36), gait with a GAITRite walkway, balance performance with Modified-Figure-Eight test and one-leg stance, fall-related concerns with Falls Efficacy Scale International, and physical function with the advanced lower extremity subscale of the questionnaire Late Life Function and Disability Instrument. Statistical methods used were multivariate logistic regression and logistic generalized estimating equation.

Results:

Sixty-eight participants completed the short-term follow-up at 3 months, and 53 participants completed the long-term follow-up at 15 months. Per-protocol analysis (n = 68) showed that the odds ratio for having a daily step count of 5000 or more at 3 months was 6.17 (95% confidence interval, 1.23-30.91), P = .027, for the intervention group compared with the control group. The longitudinal analysis (n = 91) showed that the odds ratio for having a daily step count of 5000 or more at 15 months was 2.02 (95% confidence interval, 0.88-4.64), P = .096, for the intervention group compared with the control group. The mental component sum of the SF-36 improved significantly from baseline to 3 months in the intervention group, and the physical component sum improved in both groups, but no statistically significant differences were found between groups. No associations were found between PA and changes in covariates.

Discussion and Conclusions:

The short-term evaluation showed that balance training increased habitual PA in community-dwelling older adults with osteoporosis. A significantly higher proportion of participants in the intervention group reached a level of 5000 or more steps/day, which is important for overall health. This effect was not associated with improvements in HRQoL, gait speed, balance performance, or fall-related concerns, and did not persist through the long-term follow-up. To accomplish a sustained PA change, a prolonged intervention or more support regarding habitual PA may be required, such as reinforcement with personalized behavior change counseling or PA on prescription.

Objectively Assessed Physical Activity and its Association with Balance, Physical Function and Dyskinesia in Parkinson's Disease

BACKGROUND

The desirable effects of physical activity in individuals with Parkinson's disease are well-known, although according to results from previous studies factors associated with objectively assessed physical activity are not fully investigated.

OBJECTIVE

To investigate demographic, disease-related and mobility-related factors that associate with objectively measured physical activity, in a sample of older adults with mild to moderate Parkinson's disease.

METHODS

Demographic, disease-related and mobility-related factors were gathered by interview from a total of 91 older adults with Parkinson's disease, followed by an evaluation of balance control using the Mini-BESTest. After initial testing, participants wore a tri-axial accelerometer during a week of free-living. Correlation analysis and multiple linear regression was used to investigate factors associated with total PA, represented by total activity counts, and time in brisk walking.

RESULTS

Motor impairment, physical function, body mass index and dyskinesia contributed to the variance of total physical activity, explaining 34 % of the variance, while physical function and balance control were significant factors associated with brisk walking, explaining 22 %.

CONCLUSIONS

This study identified factors that have not been shown to associate with objectively measured physical activity previously, such as dyskinesia, balance control and self-rated physical function. The findings also demonstrated that associated factors differ, depending on the activity behavior being investigated. However, other factors than those included in this study may also be of importance.

Psychometric properties of the Swedish version of the Falls Efficacy Scale-International for older adults with osteoporosis, self-reported balance deficits and fear of falling

PURPOSE

Investigate the psychometric properties of the Swedish version of the Falls Efficacy Scale-International (FES-I).

METHOD

Cross-sectional study. Community-dwelling older adults with self-reported balance deficits and fear of falling were recruited from an ongoing randomised controlled study to evaluate the psychometric properties of the FES-I using Rasch model analysis.

RESULTS

The Rasch model analysis revealed good category function, the questionnaire measured one dimension with an explained variance of 68.6% and item goodness-of-fit with mean square values (MnSq) 0.7-1.44. The item map showed that all items are spread over the scale, which indicates different difficulties in the items. Non-satisfactory person goodness-of-fit was shown with seven persons and showed person misfit according to both the MnSq-value and the z-value, 38 persons (40%) showed a person misfit when only following the threshold for MnSq.

CONCLUSIONS

The Swedish version of FES-I shows good psychometric properties with unidimensionality and item goodness-of-fit. Lower person goodness-of-fit was shown probably because of confounding factors that may influence the answers. The transformed values of the FES-I make it possible to use parametric statistics preferable for this population in future research. Implications for rehabilitation The Falls Efficacy Scale-International (FES-I) shows good psychometric properties with unidimensionality, item goodness-of-fit and good item reliability, which means that FES-I is a valuable tool when measuring concerns about falling in an older population with osteoporosis and could be useful in clinical settings. Confounding factors such as pain, high number of falls, low fall self-efficacy, experience of previous falls, and vertigo may influence the answers and result in low person goodness-of-fit.

Assessing postural balance in early Parkinson's Disease-validity of the BDL balance scale

BACKGROUND

There is a need for a valid assessment test of balance in early Parkinson's disease (PD).

OBJECTIVE

To validate the Bäckstrand Dahlberg Liljenäs Balance Scale (BDL), a test of balance performance constructed to assess mild to moderate balance disability due to neurological disease, for use in persons with early PD.

METHODS

Cross-sectional psychometric evaluation study from a convenience sample community-dwelling persons with PD (n = 28).

MAIN MEASURES

The BDL was validated using the Berg Balance Scale (BBS), the motor part of the Unified Parkinson's Disease Rating Scale (mUPDRS), the Timed Up and Go (TUG) and Timed Up and Go-cognition (CTUG). Correlations were calculated by Spearman's rank correlation coefficient (rho). Rasch analyses were used to test the internal construct of the BDL. The result from the BDL was compared to a healthy reference group.

RESULTS

The correlation between the BDL and the BBS (rho = 0.703) was high positive, while for mUPDRS (rho = -0.280), TUG (rho = -0.321) and CTUG (rho = -0.361) the correlations with the BDL were negligible to low negative. The Rasch analyses for the BDL showed a good distribution of the task difficulties with neither ceiling nor floor effect among individual measures. There was a significant difference (p = 0.03) in performance of the BDL between the PD group and the healthy reference group.

CONCLUSIONS

The BDL Balance Scale can be considered a valid clinical assessment test when evaluating balance training interventions in persons with early PD. It can be recommended as an outcome measure in clinical practice and in clinical research within this population.

Falls and fear of falling predict future falls and related injuries in ambulatory individuals with spinal cord injury: a longitudinal observational study

QUESTIONS

What is the 1-year incidence of falls and injurious falls in a representative cohort of community-dwelling ambulatory individuals with chronic spinal cord injury? What are the predictors of recurrent falls (more than two/year) and injurious falls in this population?

DESIGN

One-year longitudinal observational multi-centre study.

PARTICIPANTS

A representative sample of 68 (of 73 included) community-dwelling ambulatory individuals with traumatic SCI attending regular follow-up programs at rehabilitation centres.

OUTCOME MEASURES

Primary outcome measures were incidence and predictors of recurrent falls (more than two/year) and injurious falls reported every 2 weeks for 1year.

RESULTS

A total of 48% of participants reported recurrent falls. Of the 272 reported falls, 41% were injurious. Serious injuries were experienced by 4% of participants, all of whom were women. Multivariate logistic regression analysis showed that recurrent falls in the previous year (OR=111, 95% CI=8.6 to 1425), fear of falling (OR=6.1, 95% CI=1.43 to 26) and longer time taken to walk 10m (OR=1.3, 95% CI=1.0 to 1.7) were predictors of recurrent falls. Fear of falling (OR=4.3, 95% CI=1.3 to 14) and recurrent falls in the previous year (OR=4.2, 95% CI=1.2 to 14) were predictors of injurious falls.

CONCLUSION

Ambulatory individuals have a high risk of falling and of fall-related injuries. Fall history, fear of falling and walking speed could predict recurrent falls and injurious falls. Further studies with larger samples are needed to validate these findings. [Jørgensen V, Butler Forslund E, Opheim A, Franzén E, Wahman K, Hultling C, Seiger Å, Ståhle A, Stanghelle JK, Roaldsen KS (2017) Falls and fear of falling predict future falls and related injuries in ambulatory individuals with spinal cord injury: a longitudinal observational study.

Predictors of healthy behaviours in Swedish school children

AIM

To evaluate the impact of predictors of adopting a healthy lifestyle in Swedish schoolchildren.

METHODS

A sample of 1409 Swedish schoolchildren (mean age 12.5 years) representative of different socio-economic and geographical living areas participated in a questionnaire-based survey on healthy habits and knowledge of healthy behaviour. A logistic regression analysis was performed to identify intrapersonal, social and environmental predictors of healthy habits.

RESULTS

A normal body mass index (intrapersonal determinant) was connected to refraining from tobacco (P<0.05). For children to perceive family (P<0.001), themselves (P<0.001), or someone else (P<0.01) as a source of inspiration (social determinant) to be physically active was related to a high physical activity level. Paternal (P=0.01) and maternal (P<0.001) attention to the use of tobacco (social determinant) was of importance for children to refrain from such habits. To live in a socio-economically wealthy area (environmental determinant) was of importance for healthy food choices (P<0.01) and physical activity (P<0.05). Children from rural (P<0.01) areas (environmental determinant) were more physically active than children from urban areas.

CONCLUSION

Social aspects such as parental support for physical activity and refraining from tobacco were found to be important for healthy behaviours. Moreover, environmental factors such as socio-economic and geographical living area favourably influenced food choices and physical activity. Parental attitudes and economy are therefore important for physical activity, healthy food choices and refraining from tobacco in children. Consequently, future interventions need to address the psychological and environmental influences of the home environment through the active involvement of parents, even in school-based interventions.

Long-term effects of a progressive and specific balance-training programme with multi-task exercises for older adults with osteoporosis: a randomized controlled study

OBJECTIVE

To evaluate long-term effects of balance-training on concerns about falling, gait, balance performance, and physical function in older adults with osteoporosis and increased risk of falling.

DESIGN

Randomized controlled trial, including three groups (training, training+physical activity, and control group), with follow-ups at three, nine, and 15 months. Short-term, three-month follow-up, benefits for those who fulfilled the first follow-up ( n = 69) have previously been reported.

SETTING

Stockholm, Sweden.

PARTICIPANTS

A total of 96 elderly, age 66-87, with verified osteoporosis.

INTERVENTIONS

Balance-training programme including dual- and multitasks, with or without supplementary physical activity, three times/week over 12 weeks.

MEASUREMENTS

Concerns about falling Falls Efficacy Scale -International (FES-I), walking at preferred speed with and without a cognitive dual-task and at fast speed, balance tests (one-leg stance and modified figure-of-eight), and physical function Late-Life Function and Disability Instrument (LLFDI).

RESULTS

Participants in the training group maintained positive effects throughout the study period for concerns about falling (baseline vs. 15 months, median 27.5 vs. 23 points, p < 0.001) and walking performance (baseline vs. 15 months, p ⩽ 0.05 with an improvement of 0.9-1.4 m/s). The Training+physical activity group declined to baseline values at the nine-month follow-up, and were even lower at the 15-month follow-up for concerns about falling (median 26 vs. 26 points), walking performance (changes of -0.02 to 0.04 m/s), and physical function (mean 44.0 vs. 42.9 points). The control group remained unchanged throughout the study period.

CONCLUSIONS

This balance-training programme reduced concerns about falling, and also improved gait in older adults with osteoporosis and increased risk of falling in a long-term perspective - important issues for fall prevention.

Accelerometer Cut Points for Physical Activity Assessment of Older Adults with Parkinson's Disease

Objective

To define accelerometer cut points for different walking speeds in older adults with mild to moderate Parkinson’s disease.

Method

A volunteer sample of 30 older adults (mean age 73; SD 5.4 years) with mild to moderate Parkinson’s disease walked at self-defined brisk, normal, and slow speeds for three minutes in a circular indoor hallway, each wearing an accelerometer around the waist. Walking speed was calculated and used as a reference measure. Through ROC analysis, accelerometer cut points for different levels of walking speed in counts per 15 seconds were generated, and a leave-one-out cross-validation was performed followed by a quadratic weighted Cohen’s Kappa, to test the level of agreement between true and cut point–predicted walking speeds.

Results

Optimal cut points for walking speeds ≤ 1.0 m/s were ≤ 328 and ≤ 470 counts/15 sec; for speeds > 1.3 m/s, they were ≥ 730 and ≥ 851 counts/15 sec for the vertical axis and vector magnitude, respectively. Sensitivity and specificity were 61%–100% for the developed cut points. The quadratic weighted Kappa showed substantial agreement: κ = 0.79 (95% CI 0.70–0.89) and κ = 0.69 (95% CI 0.56–0.82) for the vertical axis and the vector magnitude, respectively.

Conclusions

This study provides accelerometer cut points based on walking speed for physical-activity measurement in older adults with Parkinson’s disease for evaluation of interventions and for investigating links between physical activity and health.

"Better safe than sorry": a qualitative content analysis of participant's perspectives of fall-related concerns and balance in older women with osteoporosis after balance training

PURPOSE

To explore how older women with osteoporosis perceive fall-related concerns and balance in daily life after having participated in balance training.

METHODS

Explorative study. Semi-structured interviews were conducted with 19 women (66-84 years), with osteoporosis recruited from an ongoing RCT; participants were asked about their perceived fall-related concerns and balance. Interviews were taped and transcribed verbatim. Data were analyzed using inductive qualitative content analysis.

RESULTS

One underlying theme emerged: "Internalized risk perception related to experience of bodily fragility", and three manifest categories: empowerment, safety and menace. A dynamic process between the categories was found, in which contextual and personal factors influenced perceptions of fall-related concerns and balance, i.e. winter season may lead a person who is highly empowered and/or uses active strategies into a situation of perception of menace and avoidance of activity.

CONCLUSION

To cope with the fragility caused by osteoporosis informants had an internalized risk perception that protected them against possible threats and harm. Informants perceived improved empowerment and self-efficacy after participation in balance training. They resumed activities and became more active and independent in daily life using safety precautions and fall-prevention strategies. Depending on contextual factors, some situations still invoked fear and led to avoidance. Implication for Rehabilitation Risk awareness protecting against possible threats and harms seems to be internalized in older women living with osteoporosis. When designing fall prevention programs, it is important to recognize that contextual and personal factors have a major influence on how older women with osteoporosis perceive fall-related concerns and balance. Perception of fragility and risk seems to be a significant problem for older women with osteoporosis and health-care providers should encourage their patients to participate in tailored balance training programs to overcome these concerns.

The Effects of Highly Challenging Balance Training in Elderly With Parkinson's Disease: A Randomized Controlled Trial

Background. Highly challenging exercises have been suggested to induce neuroplasticity in individuals with Parkinson’s disease (PD); however, its effect on clinical outcomes remains largely unknown. Objective. To evaluate the short-term effects of the HiBalance program, a highly challenging balance-training regimen that incorporates both dual-tasking and PD-specific balance components, compared with usual care in elderly with mild to moderate PD. Methods. Participants with PD (n = 100) were randomized, either to the 10-week HiBalance program (n = 51) or to the control group (n = 49). Participants were evaluated before and after the intervention. The main outcomes were balance performance (Mini-BESTest), gait velocity (during normal and dual-task gait), and concerns about falling (Falls Efficacy Scale–International). Performance of a cognitive task while walking, physical activity level (average steps per day), and activities of daily living were secondary outcomes. Results. A total of 91 participants completed the study. After the intervention, the between group comparison showed significantly improved balance and gait performance in the training group. Moreover, although no significant between group difference was observed regarding gait performance during dual-tasking; the participants in the training group improved their performance of the cognitive task while walking, as compared with the control group. Regarding physical activity levels and activities of daily living, in comparison to the control group, favorable results were found for the training group. No group differences were found for concerns about falling. Conclusions. The HiBalance program significantly benefited balance and gait abilities when compared with usual care and showed promising transfer effects to everyday living. Long-term follow-up assessments will further explore these effects.

The Mini-BESTest--a clinically reproducible tool for balance evaluations in mild to moderate Parkinson's disease?

Background

The Mini-BESTest is a clinical balance test that has shown a high sensitivity in detecting balance impairments in elderly with Parkinson's disease (PD). However, its reproducibility between different raters and between test occasions has yet to be investigated in a clinical context. Moreover, no one has investigated the reproducibility of the Mini-BESTest's subcomponents (i.e. anticipatory postural adjustments; postural responses; sensory orientation and dynamic gait).

We aimed to investigate the inter-rater and test-retest reproducibility (reliability as well as agreement) of the Mini-BESTest, as well as its subcomponents, in elderly with mild to moderate PD, performed under conditions assimilating clinical practice.

Method

This was an observational measurement study with a test-retest design.

Twenty-seven individuals with idiopathic PD (66 - 80 years, mean age: 73; Hoehn & Yahr: 2-3; 1-15 years since diagnosis) were included. Two test administrators, having different experiences with the Mini-BESTest, administered the test individually, in separate rooms in a hospital setting. For the test-retest assessment, all participants returned 7 days after the first test session to perform the Mini-BESTest under similar conditions. Intra-class correlation coefficients (ICC_2.1), standard error of measurement (SEM_agreement), and smallest real difference (SRD) were analyzed.

Results

The Mini-BESTest showed good reliability for both inter-rater and test-retest reproducibility (ICC = 0.72 and 0.80). Regarding agreement, the measurement error (SRD) was found to be 4.1 points (accounting for 15% of the maximal total score) for inter-rater reproducibility and 3.4 points (12% of the maximal total score) for test-retest reproducibility. The investigation of the Mini-BESTest's subcomponents showed a similar pattern for both inter-rater and test-retest reproducibility, where postural responses had the largest proportional measurement error, and sensory orientation showed the highest agreement.

Conclusions

Our findings indicate that the Mini-BESTest is able to distinguish between individuals with mild to moderate PD; however, when used in clinical balance assessments, the large measurement error needs to be accounted for.

Taking balance training for older adults one step further: the rationale for and a description of a proven balance training programme

Objective:

To give the rationale and evidence for and a detailed description of a rehabilitation programme of proven effectiveness in improving balance in older adults.

Background theory and evidence:

Based on the knowledge that balance loss usually occurs in situations when attention is divided, especially when being older, and that balance control relies on the interaction of several physiological systems, we have developed a specific and progressive balance training programme with dual- and multi-task exercises for older adults.

Practical application:

Balance demanding exercises, specific to the various components of balance control and to situations in daily life, were performed in sitting, standing and walking at three different levels of progression (basic, moderate and advanced) of increasing difficulty and complexity. The training was performed in 45-minutes group sessions, with 6–10 participants in each group, three times per week during 12 weeks, with two or three physiotherapists present.

Conclusions:

This balance training programme strengthens self-efficacy in balance control leading to improved fall-related self-efficacy, reduced fear of falling, increased walking speed, and improved physical function. Participants found the programme motivating, valuable, fun, and enjoyable, which was reflected in a high attendance rate.

Balance training with multi-task exercises improves fall-related self-efficacy, gait, balance performance and physical function in older adults with osteoporosis: a randomized controlled trial

OBJECTIVE

To evaluate the effects of a balance training program including dual- and multi-task exercises on fall-related self-efficacy, fear of falling, gait and balance performance, and physical function in older adults with osteoporosis with an increased risk of falling and to evaluate whether additional physical activity would further improve the effects.

DESIGN

Randomized controlled trial, including three groups: two intervention groups (Training, or Training+Physical activity) and one Control group, with a 12-week follow-up.

SETTING

Stockholm County, Sweden.

PARTICIPANTS

Ninety-six older adults, aged 66-87, with verified osteoporosis.

INTERVENTIONS

A specific and progressive balance training program including dual- and multi-task three times/week for 12 weeks, and physical activity for 30 minutes, three times/week.

MAIN MEASURES

Fall-related self-efficacy (Falls Efficacy Scale-International), fear of falling (single-item question - 'In general, are you afraid of falling?'), gait speed with and without a cognitive dual-task at preferred pace and fast walking (GAITRite®), balance performance tests (one-leg stance, and modified figure of eight), and physical function (Late-Life Function and Disability Instrument).

RESULTS

Both intervention groups significantly improved their fall-related self-efficacy as compared to the controls (p ≤ 0.034, 4 points) and improved their balance performance. Significant differences over time and between groups in favour of the intervention groups were found for walking speed with a dual-task (p=0.003), at fast walking speed (p=0.008), and for advanced lower extremity physical function (p=0.034).

CONCLUSIONS

This balance training program, including dual- and multi-task, improves fall-related self-efficacy, gait speed, balance performance, and physical function in older adults with osteoporosis.

Task-specific balance training improves self-assessed function in community-dwelling older adults with balance deficits and fear of falling: a randomized controlled trial

Objective:

To evaluate the effects of a 12-week balance training programme on self-assessed function and disability in healthy community-dwelling older adults with self-perceived balance deficits and fear of falling.

Design:

A prospective, randomized controlled trial.

Setting:

Stockholm County, Sweden.

Participants:

A total of 59 community-dwelling older adults (42 women and 17 men) aged 67–93 were randomized to either an intervention group (n = 38) or to serve as controls (n = 21) after baseline testing.

Intervention:

The intervention was a 12-week, three times per week, progressive, specific and individually adjusted group balance-training programme.

Main measures:

Self-perceived function and disability measured with Late Life Function and Disability Instrument.

Results:

The intervention group reported improvement in overall function (p = 0.016), as well as in basic (p = 0.044) and advanced lower extremity function (p = 0.025) compared with the control group. The study showed no improvement in overall disability or upper extremity function.

Conclusion:

This group balance training programme improves self-assessed function in community-dwelling older adults with balance deficits and fear of falling.

Is highly challenging and progressive balance training feasible in older adults with Parkinson's disease?

OBJECTIVE

To develop a highly challenging and progressive group balance training regime specific to Parkinson's disease (PD) symptoms and to investigate its feasibility in older adults with mild to moderate PD.

DESIGN

Intervention study, before-after trial with a development and feasibility design.

SETTING

University hospital setting.

PARTICIPANTS

Feasibility was evaluated in older adults (N=5; mean age, 72y; age range, 69-80y) with mild to moderate idiopathic PD.

INTERVENTION

A balance training regime emphasizing specific and highly challenging exercises, performed 3 times per week for 12 weeks, was developed through discussion and workshops by a group of researchers and physiotherapists.

MAIN OUTCOME MEASURES

Indicators of feasibility included attendance rate, safety (adverse events, physical function, and pain), participants' perceptions of the intervention (level of difficulty of the exercises, motivation level, and appreciation), and efficacy of the intervention (balance performance assessed with the Mini-Balance Evaluation Systems Test [Mini-BESTest]).

RESULTS

The incidence rate was high (93%) for attendance and low (1.2%) for adverse events. Ratings by the participants indicated progression throughout the training period. All participants considered the training motivational and stated that they would recommend it to others. The efficacy of the intervention measured with the Mini-BESTest showed that 4 out of 5 participants improved their balance performance.

CONCLUSIONS

These findings support the overall feasibility of this novel balance program in older adults with mild to moderate PD. However, to further evaluate the efficacy of the program, a larger randomized controlled trial is required.

Self-reported function and disability in late life - cross-cultural adaptation and validation of the Swedish version of the late-life function and disability instrument

Purpose

To translate and perform a cross-cultural adaptation of the Late-Life Function and Disability Instrument (LLFDI) to Swedish, to investigate absolute and relative reliability, concurrent validity, and floor and ceiling effects within a Swedish-speaking sample of community-dwelling older adults with self-reported balance deficits and fear of falling.

Method

Translation, reliability and validation study of the LLFDI. Sixty-two community-dwelling, healthy older adults (54 women and 8 men) aged 68–88 years with balance deficits and fear of falling performed the LLFDI twice with an interval of 2 weeks.

Results

Test–retest agreement, intra-class correlation coefficient was very good, 0.87–0.91 in the LLFDI function component and 0.82–0.91 in the LLFDI disability component. The standard error of measure was small, 5–9%, and the smallest real difference was 14–24%. Internal consistency (Cronbach’s alpha) was high (0.90–0.96). Correlation with the SF-36 PCS and PF-10 was moderate in both LLFDI function, r = 0.39–0.68 and r = 0.35–0.52, and LLFDI disability, r = 0.40–0.63 and 0.34–0.57, respectively. There was no floor or ceiling effects.

Conclusion

The Swedish version of the LLFDI is a highly reliable and valid instrument for assessing function and disability in community-dwelling older women with self-reported balance deficits and fear of falling.

Implications for Rehabilitation

The Swedish LLFDI is a highly reliable and valid instrument for assessing function and disability in older women with self-reported balance deficits and fear of falling.

The instrument may be used both in clinical settings and in research.

The instrument is sensitive to change and a reasonably small improvement is enough to detect changes in a group or a single individual.

Assessing the relative and absolute reliability of the Falls Efficacy Scale-International questionnaire in elderly individuals with increased fall risk and the questionnaire's convergent validity in elderly women with osteoporosis

The Falls Efficacy Scale-International (FES-I) is a highly reliable questionnaire for assessing fear of falling in elderly individuals with increased fall risk and has low or no convergent validity with balance performance tests and health-related quality of life (HRQL) among elderly women with osteoporosis, which indicates that both measurements should be included as they are measuring different components.

INTRODUCTION

Fear of falling is increased in elderly individuals with osteoporosis and FES-I is a widely used questionnaire to assess fear of falling. There is limited evidence of the reliability and convergent validity in elderly with increased risk of falling and osteoporosis.

METHODS

Reliability and validity study of the FES-I. Community-dwelling elderly with increased fall risk, 59 subjects, were recruited to the reliability assessment, and 81 women with osteoporosis, in the validity assessment. For the reliability assessment, two postal surveys were used. For the validity assessment, we used baseline data from an on-going study in women with osteoporosis. The FES-I was correlated to a single-item question regarding fear of falling, self-reported history of falls, balance performance tests and health-related quality of life.

RESULTS

The FES-I had very good relative reliability (intra-class correlation 0.88) and internal consistency reliability (Cronbach's alpha 0.94). The value for absolute reliability was a standard error of measure 2.9 (10.6 %), smallest real difference 7.9 (29 %). There was "little if any" to "low" correlation between the FES-I and the single-item question regarding fear of falling and self-reported history of falls, HRQL and balance performance tests.

CONCLUSION

The FES-I seems to be a highly reliable questionnaire for assessing fear of falling in elderly with increased fall risk but has low relation to/convergent validity with balance performance and HRQL among elderly women with osteoporosis.

Long-term effects of new progressive group balance training for elderly people with increased risk of falling - a randomized controlled trial

OBJECTIVE

To evaluate the long-term effects of a progressive and specific balance group-based program in healthy elderly individuals with increased risk of falling.

DESIGN

Follow-up of a randomized controlled trial at nine and 15 months on a population that has previously been described at three months.

SETTING

The study was conducted in Stockholm, Sweden.

SUBJECTS

59 community-dwelling elderly (age 67-93 years), recruited by advertisement, were randomly allocated to training or to serve as controls.

INTERVENTION

Group balance training three times per week during 12 weeks with a 15 month follow-up time.

MAIN MEASURES

Participants were assessed at baseline, three, nine, and 15 months thereafter for gait function (preferred and fast walking), rapid step execution (single and dual task), fear of falling, and likelihood of depression.

RESULTS

Fast gait speed (p = 0.004), dual task step execution (p = 0.006) and fear of falling (p = 0.001) were still improved in the training group at nine months follow-up. Only self-perceived fear of falling remained significantly improved (p = 0.012) at 15 months follow-up. Although fast gait speed had decreased to baseline level in the training group (1.49 m/s) it remained significantly higher than in the control group (1.37 m/s) at the end of the study, a difference between the groups that was not seen at baseline.

CONCLUSION

This training program provided important positive short and long-term benefits to gait, balance function, and fear of falling.

A novel conceptual framework for balance training in Parkinson's disease-study protocol for a randomised controlled trial

Background

There is increasing scientific knowledge about the interaction between physiological (musculoskeletal, neuromuscular, cognitive and sensory) systems and their influence on balance and walking impairments in Parkinson’s disease. We have developed a new conceptual framework for balance training, emphasising specific components of balance control related to Parkinson’s disease symptoms by using highly challenging, progressive and varying training conditions. The primary aim of this proposed randomised controlled trial will be to investigate the short-term and long-term effects of a 10-week balance training regime in elderly with Parkinson’s disease.

Methods/Design

Eighty participants with mild to moderate idiopathic Parkinson’s disease will be recruited and randomly allocated to an intervention group receiving balance training or a control group whose participants will continue to receive their usual care. The intervention will consist of a 10-week group training regime (1-hour training, three times per week), which will be led by two physiotherapists to ensure training progression and safety. The conceptual framework will be applied by addressing specific balance components (sensory integration, anticipatory postural adjustments, motor agility, stability limits) through varying training conditions and structured progression. Assessment will be conducted through a multi-dimensional battery of outcomes, prior to and immediately after the 10-week intervention, and at 9 and 15 months’ follow-up after entering the study. Primary outcome measures will be balance performance (assessed using the Mini Balance Evaluation Systems Test), change in gait velocity (m/s) between single and dual task walking, and fear of falling (evaluated using the Fall Efficacy Scale International).

Discussion

This study has the potential to provide new insight and knowledge of the effects of specific, varied and challenging balance training on a wide health spectrum in elderly with PD. If found to be effective, this pragmatic approach with translation of theory into practice, can be implemented in existing outpatient care.

Effects of new, individually adjusted, progressive balance group training for elderly people with fear of falling and tend to fall: a randomized controlled trial

Objective: To evaluate the effects of a new, individually adjusted, progressive and specific balance group training programme on fear of falling, step execution, and gait in healthy elderly people with fear of falling and tend to fall.

Design: Randomized controlled trial.

Setting: The study was conducted in Stockholm County, Sweden.

Subjects: Fifty-nine community dwelling elderly people were recruited by advertisement, and allocated at random to an intervention group ( n = 38) or a control group ( n = 21).

Intervention: Individually adjusted, progressive and specific balance group training was given three times a week for three months. The training incorporated elements included in, and required for, independent activities of daily living, and for reactions to loss of balance during dual or multiple tasks.

Main measures: Fear of falling was assessed with Falls Efficacy Scale International (FES-I). The reaction time of step execution was measured with the step-execution test, and gait was measured with GAITRite®.

Results: After three months the intervention group showed significant positive changes in the FES-I ( P = 0.008), in the step-execution phase of dual-task performance ( P = 0.012), and in gait at preferred speed during single-task performance; in cadence ( P = 0.030) and, at fast speed, in velocity ( P = 0.004) and cadence ( P = 0.001). Significant decreases were also found for the likelihood of depression after participating in the training programme.

Conclusion: This new balance training programme is feasible and leads to decreased fear of falling, decreased time for step execution during dual-task performance and increased velocity during fast walking.

Factors associated with patients self-reported adherence to prescribed physical activity in routine primary health care

Background

Written prescriptions of physical activity have increased in popularity. Such schemes have mostly been evaluated in terms of efficacy in clinical trials. This study reports on a physical activity prescription referral scheme implemented in routine primary health care (PHC) in Sweden. The aim of this study was to evaluate patients' self-reported adherence to physical activity prescriptions at 3 and 12 months and to analyse different characteristics associated with adherence to these prescriptions.

Methods

Prospective prescription data were obtained for the general population in 37 of 42 PHC centres in Östergötland County, during 2004. The study population consisted of 3300.

Results

The average adherence rate to the prescribed activity was 56% at 3 months and 50% at 12 months. In the multiple logistic regression models, higher adherence was associated with higher activity level at baseline and with prescriptions including home-based activities.

Conclusions

Prescription from ordinary PHC staff yielded adherence in half of the patients in this PAR scheme follow-up.

Is there a demand for physical activity interventions provided by the health care sector? Findings from a population survey

Background

Health care providers in many countries have delivered interventions to improve physical activity levels among their patients. Thus far, less is known about the population's interest to increase their physical activity levels and their opinion about the health care provider's role in physical activity promotion. The aims of this paper were to investigate the self-reported physical activity levels of the population and intention to increase physical activity levels, self-perceived need for support, and opinions about the responsibilities of both individuals and health care providers to promote physical activity.

Methods

A regional public health survey was mailed to 13 440 adults (aged 18-84 years) living in Östergötland County (Sweden) in 2006. The survey was part of the regular effort by the regional Health Authorities.

Results

About 25% of the population was categorised as physically active, 38% as moderately active, 27% as somewhat active, and 11% as low active. More than one-third (37%) had no intentions to increase their physical activity levels, 36% had thought about change, while 27% were determined to change. Lower intention to change was mainly associated with increased age and lower education levels. 28% answered that physical activity was the most important health-related behaviour to change "right now" and 15% of those answered that they wanted or needed support to make this change. Of respondents who might be assumed to be in greatest need of increased activity (i.e. respondents reporting poor general health, BMI>30, and inactivity) more than one-quarter wanted support to make improvements to their health. About half of the respondents who wanted support to increase their physical activity levels listed health care providers as a primary source for support.

Conclusions

These findings suggest that there is considerable need for physical activity interventions in this population. Adults feel great responsibility for their own physical activity levels, but also attribute responsibility for promoting increased physical activity to health care practitioners.

Physical activity referrals in Swedish primary health care - prescriber and patient characteristics, reasons for prescriptions, and prescribed activities

BACKGROUND

Over the past decade, practitioners in primary health care (PHC) settings in many countries have issued written prescriptions to patients to promote increased physical activity or exercise. The aim of this study is to describe and analyse a comprehensive physical activity referral (PAR) scheme implemented in a routine PHC setting in Ostergötland County. The study examines characteristics of the PARs recipients and referral practitioners, identifies reasons why practitioners opted to use PARs with their clients, and discusses prescribed activities and prescriptions in relation to PHC registries.

METHODS

Prospective prescription data were obtained for 90% of the primary health care centres in Ostergötland County, Sweden, in 2004 and 2005. The study population consisted of patients who were issued PARs after they were deemed likely to benefit from increased physical activity, as assessed by PHC staff.

RESULTS

During the two-year period, a total of 6,300 patients received PARs. Two-thirds of the patients were female and half of the patients were 45-64 years. Half of the patients (50.8%) who received PARs were recommended a home-based activity, such as walking. One third (33%) of the patients issued PARs were totally inactive, reporting no days of physical activity that lasted for 30 minutes, and 29% stated that they reached this level 1-2 days per week. The number of PARs prescribed per year in relation to the number of unique individuals that visited primary health care during one year was 1.4% in 2004 and 1.2% in 2005. Two-thirds of the combined prescriptions were issued by physicians (38%) and nurses (31%). Physiotherapists and behavioural scientists issued the highest relative number of prescriptions. The most common reasons for issuing PARs were musculoskeletal disorders (39.1%) and overweight (35.4%), followed by high blood pressure (23.3%) and diabetes (23.2%).

CONCLUSION

Ostergötland County's PAR scheme reached a relatively high proportion of physically inactive people visiting local PHC centres for other health reasons. PAR-related statistics, including PAR-rates by individual PHC centres and PAR- rates per health professional category, show differences in prescribing activities, both by patient categories, and by prescribing professionals.

Does a physical activity referral scheme improve the physical activity among routine primary health care patients?

Physical activity referral (PAR) schemes or concepts occur in varying forms. Because few physical activity intervention studies have been carried out in routine health care settings, it is difficult to translate research findings into daily practice. The aim of this study was to analyze the effectiveness of a PAR scheme implemented in routine primary health care. The study did not include a control group and was based on the ordinary staff's work efforts and follow-up measures. During a 2-year period, 6300 PARs were issued. Effectiveness was measured by an increase in self-reported physical activity. Half of the patients reached reported increased physical activity both at 3 months (49%) and at 12 months (52%). The proportion of inactive patients decreased from 33% at baseline to 17% at 3 months and 20% at 12 months. The proportion of patients who were physically active on a regular basis increased from 22% at baseline to 33% at 3 months and 32% at 12 months. Neither the patient's age nor the profession of the prescriber was associated with differences in effectiveness. The patient's activity level at baseline, the type of physical activity as well as the reason for the prescription were associated with increased physical activity.

Impact of time trends and increasing age on health behaviour of Swedish school children

BACKGROUND

Information on trends in healthy and unhealthy habits among children are important for the development of programmes intended to foster and consolidate a healthy lifestyle. This report studied the importance of time and age on the health behaviour of Swedish school children.

METHODS

A comparison between health behaviours derived from repeated evaluations of Swedish school children aged 11-13 years was performed.

RESULTS

Significant positive time trends were found in the form of increased physical activity and decreased sedentary behaviours, whereas negative time trends were observed in dietary habits and smoking. An analysis of the impact of increasing age demonstrated a negative influence including less physical activity and deteriorating dietary habits and increased smoking at the young age groups in this study.

CONCLUSION

Time trends and age are both important determinants of health behaviour in pre-teen children. Even the small age increase from 11 to 13 years had an important negative influence. The results of the present study underline that the window of opportunities to promote a healthy lifestyle in children is narrow. It is evident that a successful health intervention programme must be initiated at an early age, continued and repeated over time, and structured to counteract trends in age as well as time.

Physical activity on prescription in primary health care: a follow-up of physical activity level and quality of life

To examine whether physical activity on prescription in routine primary care patients would influence physical activity level and quality of life 6 months later. In 2001-2003, 13 Swedish primary health care units took part in an uncontrolled clinical study. If a patient in primary health care needed physical activity preventively or for treatment of a disease and patient-centered motivational counseling found physical activity to be suitable, individualized physical activity could be prescribed. Patients (n=481) of both sexes and all ages [75% women, mean age 50 (12-81)] participated in the study. Self-reported physical activity, readiness to change to a more physically active lifestyle and quality-of-life data were collected through questionnaires. The follow-up rate was 62% at 6 months. Intention-to-treat analysis showed a significant increase (P<0.01) in self-reported physical activity level, the stages of action and maintenance of physical activity as well as quality of life. Physical activity level, stages of change and quality of life increased analogically, indicating that physical activity on prescription may be suitable as a conventional treatment in an ordinary primary health care setting to promote a more physically active lifestyle.

Physical activity, body composition and physical self-esteem: a 3-year follow-up study among adolescents in Sweden

AIMS

To measure physical activity by means of daily pedometer steps, body composition, expressed as body mass index (BMI) and bioelectrical impedance as percent body fat, and perceived physical self-esteem and additionally, to evaluate eventual predictors for a healthy lifestyle i.e., highly physically active, normal weighted and a high physical self-esteem in a follow-up group.

METHODS

During autumn 2000 physical activity level was assessed and BMI was calculated in 871 children aged 7-14 in south eastern Sweden and in 501 of these, physical self-esteem were also assessed. During autumn 2003 a total of 375 adolescents aged 15-18 were assessed using the same methodology and additionally percent body fat was measured. Ninety-three of these adolescents (46 girls), were also measured in 2000 and they formed the follow-up group.

RESULTS

In the follow-up group a significant increase in BMI and stability in physical self-esteem in boys and girls, and in boys a significant decrease in daily steps was found 3 years later. Strongest predictor to be highly physically active, maintain normal BMI and high self-esteem 3 years later, i.e., to have a healthy lifestyle, was for girls increased self-esteem and for boys a decreased BMI.

CONCLUSION

Consequently, for a healthy lifestyle, promoting physical self-esteem in girls and weight control in boys is of great importance in early adolescence.
