Abstract [en]

High aerobic fitness, more moderate to vigorous physical activity (MVPA) and less sedentary behavior (SED) have all been suggested to promote cognitive functions, but it is unclear whether they are independent predictors of specific cognitive domains. This study aimed to investigate to what extent aerobic fitness MVPA and SED are independently associated with cognitive performance among middle-aged Swedish adults. We acquired device-based measures of aerobic fitness, cognitive performance and percent daily time spent in MVPA and SED in Swedish adults (n = 216; 54-66 years old). Aerobic fitness was associated with better performance at one out of two tests of speed/attention and one out of four tests of executive attention, and with worse performance at one of seven tests of memory. Increasing %MVPA was associated with better performance at one out of seven tests of memory and two out of three tests of verbal ability, whereas increasing %SED was associated with better performance at all four tests of executive attention and four out of seven tests of memory. These findings suggest that aerobic fitness, %MVPA and %SED are partly independent correlates of cognitive performance. To fully understand the association between SED and performance at several tests of cognitive function, future investigations might attempt to investigate intellectually engaging SED (such as reading books) separately from mentally undemanding SED (such as watching TV).

Abstract [en]

The unfavorable health consequences of prolonged time spent sedentary (stationary) make accurate assessment in the general population important. However, for many existing questionnaires, validity for identifying stationary time has not been shown or has shown low validity. This study aimed to assess the concurrent and convergent validity of the GIH stationary single-item question (SED-GIH). Data were obtained in 2013 and 2014 from two Swedish cohorts. A total of 711 men and women provided valid accelerometer data (Actigraph GT3X+) and were included for concurrent validity analyses. A total of 560 individuals answered three additional commonly used sedentary questions, and were included for convergent validity analysis. The SED-GIH displayed a significant correlation with total stationary time (rs = 0.48) and time in prolonged stationary time (rs = 0.44). The ROC analysis showed an AUC of 0.72 for identifying individuals with stationary time over 600 min/day. The SED-GIH correlated significantly with other previously used questions (r = 0.72-0.89). The SED-GIH single-item question showed a relatively high agreement with device-assessed stationary behavior and was able to identify individuals with high levels of stationary time. Thus, the SED-GIH may be used to assess total and prolonged stationary time. This has important implications, as simple assessment tools of this behavior are needed in public health practice and research.

Abstract [en]

AIMS:

Physical activity (PA) used as prevention and treatment of disease has created a need for effective tools for measuring patients' PA level. Our aim was therefore to assess the validity of two PA questions and their three associated answer modes.

METHODS:

Data on PA according to the PA questions and Actigraph GT3X+ accelerometers, aerobic fitness (VO2max), cardiovascular biomarkers, and self-rated general health were collected in 365 Swedish adults (21-66 years). The PA questions ask about weekly PA via categories (Categorical), an open-ended answer (Open), or specified day by day (Table).

RESULTS:

The Categorical mode, compared with the Open mode, correlated (Spearman's rho) significantly more strongly (p<0.05) with accelerometer PA (0.31 vs. 0.18) and VO2max (0.27 vs. 0.06), and the level of BMI (-0.20 vs. -0.02), waist circumference (-0.22 vs. -0.03), diastolic blood pressure (-0.16 vs. 0.08), glucose (-0.18 vs. 0.04), triglycerides (-0.31 vs. -0.07), and general health (0.35 vs. 0.19). The validity of the Categorical and Table modes were similar regarding VO2max and accelerometry, but the Categorical mode exhibited more significant and stronger correlations with cardiovascular biomarkers. The capacity of the PA questions to identify insufficiently physically active individuals ranged from 0.57 to 0.76 for sensitivity and from 0.47 to 0.79 for specificity.

CONCLUSIONS:

The Categorical mode exhibits the strongest validity and Open mode the weakest. The PA questions may be used on a population level, or as a tool for determining patents' appropriateness for treatment.

Abstract [en]

OBJECTIVE: The aim of our study is to assess the association between preoperative level of activity and recovery after breast cancer surgery measured as hospital stay, length of sick leave and self-assessed physical and mental recovery.

DESIGN: A prospective cohort study.

SETTING: Patients included were those scheduled to undergo breast cancer surgery, between February and November 2013, at two participating hospitals in the Western Region of Sweden.

PARTICIPANTS: Patients planned for breast cancer surgery filled out a questionnaire before, as well as at 3 and 6 weeks after the operation. The preoperative level of activity was self-assessed and categorised into four categories by the participants using the 4-level Saltin-Grimby Physical Activity Level Scale (SGPALS).

MAIN OUTCOME MEASURE: Our main outcome was postoperative recovery measured as length of sick leave, in-hospital stay and self-assessed physical and mental recovery.

RESULTS: 220 patients were included. Preoperatively, 14% (31/220) of participants assessed themselves to be physically inactive, 61% (135/220) to exert some light physical activity (PA) and 20% (43/220) to be more active (level 3+4). Patients operated with mastectomy versus partial mastectomy and axillary lymph node dissection versus sentinel node biopsy were less likely to have a short hospital stay, relative risk (RR) 0.88 (0.78 to 1.00) and 0.82 (0.70 to 0.96). More active participants (level 3 or 4) had an 85% increased chance of feeling physically recovered at 3 weeks after the operation, RR 1.85 (1.20 to 2.85). No difference was seen after 6 weeks.

CONCLUSIONS: The above study shows that a higher preoperative level of PA is associated with a faster physical recovery as reported by the patients 3 weeks post breast cancer surgery. After 6 weeks, most patients felt physically recovered, diminishing the association above. No difference was seen in length of sick leave or self-assessed mental recovery between inactive or more active patients.

Abstract [en]

BACKGROUND: Time spent being sedentary, regardless of time in exercise, has been associated with metabolic risk using regression modelling. By using isotemporal substitution modelling, the effect of replacing sedentary time with an equal amount of time in physical activity (PA) of different intensities can be considered. The present study aims to investigate the effect of replacing sedentary time with time in light, moderate and vigorous PA to the prevalence of the metabolic syndrome (MetS). Also, replacement of sedentary time by PA of different bout lengths was studied.

METHODS: In total, 836 participants (52% women), aged 50-64 years, from the SCAPIS pilot study were included. Daily time spent sedentary and in PA of different intensities was assessed using hip-worn accelerometers.

RESULTS: In this cross-sectional study, replacing 10 minutes of sedentary time with the same amount of light PA was associated with significant lower MetS prevalence, odds ratio (OR) 0.96 (95% confidence interval 0.93-0.98). Replacement with moderate PA resulted in even lower OR, 0.89 (0.82-0.97), with the lowest OR for vigorous PA, 0.41 (0.26-0.66). Participants with high energy intake and high daily sedentary time benefitted more from the replacement of sedentary time with light PA. Significant associations were seen for all bout lengths of light, moderate and vigorous PA in a stepwise-like fashion from one minute to up to 120 minute bouts.

CONCLUSION: Theoretical substitutions of sedentary time with PA of any intensity and of as little as one minute were associated with significantly lower ORs for MetS. This may be an easily communicable message in clinical practice and for public health purposes.

Abstract [en]

BACKGROUND: Studies have reported that early physical rehabilitation after surgical procedures is associated with improved outcome measured as shorter hospital stay and enhanced recovery. The aim of this study was to explore the relationship between the preoperative physical activity level and subsequent postoperative complications, sick-leave and hospital stay after radical prostatectomy for prostate cancer in the setting of the LAPPRO trial (LAParoscopic Prostatectomy Robot Open).

METHODS: LAPPRO is a prospective controlled trial, comparing robot-assisted laparoscopic and open surgery for localized prostate cancer between 2008 and 2011. 1569 patients aged 64 or less with an occupation were included in this sub-study. The Gleason score was <7 in 52 % of the patients. Demographics and the level of self-assessed preoperative physical activity, length of hospital stay, complications, quality of life, recovery and sick-leave were extracted from clinical record forms and questionnaires. Multivariable logistic regression, with log-link and logit-link functions, was used to adjust for potential confounding variables.

RESULTS: The patients were divided into four groups based on their level of activity. As the group with lowest engagement of physical activity was found to be significantly different in base line characteristics from the other groups they were excluded from further analysis. Among patients that were physically active preoperativelly (n = 1467) there was no significant difference between the physical activity-groups regarding hospital stay, recovery or complications. However, in the group with the highest self-assessed level of physical activity, 5-7 times per week, 13 % required no sick leave, compared to 6.3 % in the group with a physical activity level of 1-2 times per week only (p < 0.0001).

CONCLUSIONS: In our study of med operated with radical prostatectomy, a high level of physical activity preoperatively was associated with reduced need for sick leave after radical prostatectomy compared to men with lower physical activity.

TRIAL REGISTRATION: The trial is registered at the ISCRTN register. ISRCTN06393679 .

Abstract [sv]

Sammanfattning

Regelbunden fysisk aktivitet har positiva effekter på såväl riskfaktorer för hjärtkärlsjukdom som etablerad hjärt-kärlsjukdom. Aerob fysisk aktivitet på måttlig intensitet rekommenderas allmänt. Mer fysisk aktivitet på hög intensitet har potentiellt ännu större effekt, men kan också medföra ökade risker för personer med bakomliggande hjärt-kärlsjukdom.

Plötslig hjärtdöd i samband med fysisk aktivitet bland individer > 35 år orsakas nästan uteslutande av kranskärlssjukdom. För äldre idrottare (> 35 år), liksom för icke elitaktiva, saknas i dag svenska rekommendationer om hjärtscreening. Självskattningsformulär, i utvalda fall kompletterat med hjärtundersökning hos ordinarie läkare, har föreslagits kunna minska risken i denna grupp.

Plötsliga dödsfall under idrottsutövning bland unga (< 35 år) beror vanligen på tidigare odiagnostiserade medfödda eller ärftliga hjärtsjukdomar. Riksidrottsförbundet (RF) och Socialstyrelsen rekommenderar riktade hjärtkontroller av unga elitidrottare från 16 års ålder, bestående av familjehistoria, symtom, fysikalisk undersökning och vilo-EKG.
