Abstract [en]

Background: Exercise improves cardiorespiratory fitness (CRF) and reduces depressive symptoms in people with depression. It is unclear if changes in CRF are a predictor of the antidepressant effect of exercise in people with depression.

Aims: To investigate whether an increase in CRF is a predictor of depression severity reduction after 12 weeks of exercise (trial registration: DRKS study ID, DRKS00008745).

Method: The present study includes participants who took part in vigorous (n = 33), moderate (n = 38) and light (n = 39) intensity exercise and had CRF information (as predicted maximal oxygen uptake, O2max) collected before and after the intervention. Depression severity was measured with the Montgomery-Åsberg Depression Rating Scale (MADRS). O2max (L/min) was assessed with the Åstrand-Rhyming submaximal cycle ergometry test. The main analysis was conducted pooling all exercise intensity groups together.

Results: All exercise intensities improved O2max in people with depression. Regardless of frequency and intensity of exercise, an increase in post-treatment O2max was significantly associated with reduced depression severity at follow-up (B = -3.52, 95% CI -6.08 to -0.96); adjusting for intensity of exercise, age and body mass index made the association stronger (B = -3.89, 95% CI -6.53 to -1.26). Similarly, increased O2max was associated with higher odds (odds ratio = 3.73, 95% CI 1.22-11.43) of exercise treatment response (≥50% reduction in MADRS score) at follow-up.

Conclusions: Our data suggest that improvements in O2max predict a greater reduction in depression severity among individuals who were clinically depressed. This finding indicates that improvements in O2max may be a marker for the underpinning biological pathways for the antidepressant effect of exercise.

Abstract [en]

Qualitative studies identified barriers and facilitators associated with work-related sedentary behaviour. The objective of this study was to determine common perceived barriers and facilitators among office workers, assess subgroup differences, and describe sedentary behaviour. From two Swedish companies, 547 office workers (41 years (IQR = 35–48), 65% women, 66% highly educated) completed questionnaires on perceived barriers and facilitators, for which subgroup differences in age, gender, education, and workplace sedentary behaviour were assessed. Sedentary behaviour was measured using inclinometers (n = 311). The most frequently reported barrier was sitting is a habit (67%), which was reported more among women than men (X2 = 5.14, p = 0.03) and more among highly sedentary office workers (X2 = 9.26, p < 0.01). The two other most reported barriers were that standing is uncomfortable (29%) and standing is tiring (24%). Facilitators with the most support were the introduction of either standing- or walking-meetings (respectively 33% and 29%) and more possibilities or reminders for breaks (31%). The proportion spent sedentary was 64% at the workplace, 61% on working days, and 57% on non-working days. This study provides a detailed understanding of office workers’ ideas about sitting and means to reduce sitting. We advise to include the supported facilitators and individualized support in interventions to work towards more effective strategies to reduce sedentary behaviour.

Abstract [en]

Conflicting findings remain regarding associations between lifestyle behaviors and coronary artery calcium (CAC). We investigated concomitant associations of healthy food intake and cardiorespiratory fitness (CRF) with CAC. Data from 706 men and women 50 to 64 years old from the Swedish SCAPIS pilot trial were analyzed. A CAC score was calculated using the Agatston method. A Healthy Food Index (HFI) was established using data from a web-based food frequency questionnaire. CRF was assessed from a bike exercise test. Regression analyses were performed with occurrence of CAC (dichotomous) and level of CAC score in patients with CAC (continuous) as outcomes. 58% had 0 CAC score. HFI was significantly associated with having no CAC (standardized coefficient β = 0.18, p <0.001) but not with level of CAC score (β = -0.09, p = 0.34). CRF showed no significant association with having no CAC (β = -0.08, p = 0.12) or with the level of CAC score (β = -0.04, p = 0.64). However, there was an interaction between HFI and CRF (β = -0.23, p = 0.02); for increasing levels of CRF there was stronger negative association between HFI and level of CAC score, reaching β = -0.48, p = 0.045 for the highest CRF level. In conclusion, these results emphasize the importance of a healthy food intake in combination with higher CRF to counteract CAC development.

Abstract [en]

BACKGROUND: Exercise has mood-enhancing effects and can improve cognitive functioning, but the effects in first-episode psychosis (FEP) remain understudied. We examined the feasibility and cognitive effects of exercise in FEP.

METHOD: Multi-center, open-label intervention study. Ninety-one outpatients with FEP (mean age = 30 years, 65% male) received usual care plus a 12-week supervised circuit-training program, consisting of high-volume resistance exercises, aerobic training, and stretching. Primary study outcome was cognitive functioning assessed by Cogstate Brief Battery (processing speed, attention, visual learning, working memory) and Trailmaking A and B tasks (visual attention and task shifting). Within-group changes in cognition were assessed using paired sample t tests with effect sizes (Hedges' g) reported for significant values. Relationships between exercise frequency and cognitive improvement were assessed using analysis of covariance. Moderating effects of gender were explored with stratified analyses.

RESULTS: Participants exercised on average 13.5 (s.d. = 11.7) times. Forty-eight percent completed 12 or more sessions. Significant post-intervention improvements were seen for processing speed, visual learning, and visual attention; all with moderate effect sizes (g = 0.47-0.49, p < 0.05). Exercise participation was also associated with a positive non-significant trend for working memory (p < 0.07). Stratified analyses indicated a moderating effect of gender. Positive changes were seen among females only for processing speed, visual learning, working memory, and visual attention (g = 0.43-0.69). A significant bivariate correlation was found between total training frequency and improvements in visual attention among males (r = 0.40, p < 0.05).

CONCLUSION: Supported physical exercise is a feasible and safe adjunct treatment for FEP with potential cognitive benefits, especially among females.

Abstract [en]

Background: The importance of youth physical activity (PA) for adulthood PA, performance, and health was retrospectively evaluated. Methods: A total of 258,146 participants (49% women), aged 19–70, with a first-time health-profile assessment between 1982 and 2015, provided self-reported data on current perceived health, PA, lifestyle, and physical education class participation, and PA outside school hours before age 20. Data on anthropometrics, blood pressure, and estimated maximal oxygen consumption (VO2max) were obtained. Results: Women participating in physical education class, compared with those who did not, had significantly lower OR (range: 0.81–0.87) for perceiving poor overall health, general obesity, and high diastolic blood pressure after adjustment for potential confounders, and increased OR (range: 1.17–1.23) for exercising regularly and a normal/high VO2max in adulthood. For men, the ORs were significantly lower (range: 0.66–0.86) for poor perceived overall health, general, and abdominal obesity. These associations were seen for participants up to 70 years. Increased PA outside school hours revealed even stronger beneficial associations. In joint analyses, both youth and current PA were important for lower OR of poor health and being obese in adulthood. Conclusions: Physical education class participation and additional PA after school hours were both important for perceived health, PA, VO2max, and metabolic health in adulthood up to 70 years.

Abstract [en]

BACKGROUND: Physical activity (PA) and smoking cessation are included in the secondary prevention guidelines after myocardial infarction (MI), but they are still underutilised. This study aims to explore how PA level and smoking status (6-10 weeks post-MI) were associated with 1-year readmission and mortality during full follow-up time, and with the cumulative 5-year mortality.

METHODS: A population-based cohort of all hospitals providing MI-care in Sweden (SWEDEHEART-registry) in 2004-2014. PA was expressed as the number of exercise sessions of ≥ 30 min in the last 7 days: 0-1 (low), 2-4 (medium) and 5-7 (high) sessions/week. Individuals were categorised as smokers, former smokers or never-smokers. The associations were analysed by unadjusted and adjusted logistic and Cox regressions.

RESULTS: During follow-up (M = 3.58 years), a total of 1702 deaths occurred among 30 644 individuals (14.1 cases per 1000 person-years). For medium and high PA, the hazard ratios (HRs) for mortality were 0.39 and 0.36, respectively, compared with low PA. For never-smokers, the HR was 0.45 and former smokers 0.56 compared with smokers. Compared with low PA, the odds ratios (ORs) for readmission in medium PA were 0.65 and 0.59 for CVD and non-CVD causes, respectively. For high PA, the corresponding ORs were 0.63 and 0.55. The association remained in adjusted models. There were no associations between smoking status and readmission.

CONCLUSIONS: The PA level and smoking status are strong predictors of mortality post-MI and the PA level also predicts readmission, highlighting the importance of adherence to the secondary prevention guidelines.

Abstract [en]

Background Exercise is beneficial for depression, but less is known about its impact on post-intervention physical activity and sedentary behavior. The aim of this paper was to determine the extent to which participation in light-, moderate- and vigorous-intensity exercise intervention influenced habitual physical activity and sedentary behavior patterns in depressed adults. Methods Accelerometer data was collected pre- and post-intervention from depressed participants randomized to one of three 12-week intervention groups: light (n = 21), moderate (n = 25) and vigorous (n = 22) exercise. Mixed models examined changes in time spent sedentary and in light and moderate-to-vigorous physical activity (MVPA); time accumulated in sedentary and MVPA bouts; and, number of MVPA bouts and interruptions in sedentary time. Results Overall sedentary time decreased while light activity time increased across all intervention groups but not significantly so. The light exercise intervention group reduced MVPA minutes (−8.22, 95% CI: −16.44, −0.01), time in MVPA bouts (−8.44, 95% CI: −14.27, −2.62), and number of activity bouts (−0.43, 95% CI: −0.77, −0.09). The moderate exercise intervention group reduced time in MVPA bouts (−6.27, 95% CI: −11.71, −0.82) and number of sedentary interruptions (−6.07, 95% CI: −9.30, −2.84). No changes were observed for the vigorous exercise intervention group. Conclusions The exercise intervention led to an increase in overall light physical activity and decrease in sedentary time, though neither change was statistically significant. Participation in the light and moderate exercise intervention groups was associated with reductions of time in MVPA bouts, but this was not evident for the vigorous exercise intervention group.

Abstract [en]

Background: Physical exercise has well-characterized positive effects on depressive symptoms. The underlying biologic mechanisms are, however, far from established. A recently discovered mechanism has linked the enhanced conversion of kynurenine to kynurenic acid (KYNA) to an increased resilience toward stress-induced depression in mice. The aim of this study was to translate these findings to humans.

Materials and methods: Kynurenine and KYNA levels were measured by high-performance liquid chromatography in plasma samples from 117 patients affected by mild-to-moderate depression before and within a week after a 12-week training period at three different intensities. The patients were part of the Regassa study.

Results: No differences in plasma levels of kynurenine and KYNA or in their ratio could be detected between before and after training. No effect of the intensity group could be observed. No correlation with the improvement in cardiovascular fitness (Åstrand score) or the improvement in mood (Montgomery Åsberg Depression Rating Scale score) could be observed.

Limitations: As the Regassa study is based on an intention-to-treat protocol, the exact time and the exact intensity of the physical exercise are not known. Analyses of pulse data as well as personal interviews, however, were used to control the exercise protocols. Furthermore, the observations reflect chronic changes.

Conclusion: Physical exercise positively affects mood and cardiovascular fitness, but does not lead to long-lasting changes in plasma levels of kynurenine and KYNA in patients affected by mild-to-moderate depression.

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]

PURPOSE: Exercise training programs are beneficial for depression, but less is known about their impact on non-intervention physical activity patterns and sedentary behavior patterns in depressed adults. We determined the extent to which participation in light-, moderate- and vigorous-intensity exercise intervention programs influenced the habitual physical activity and sedentary behavior patterns in depressed adults.

METHODS: Accelerometer data were collected pre- and post-treatment from a subset of depressed participants randomized to one of three 12-week exercise intervention programs: light (n=21), moderate (n=25) and vigorous (n=22) exercise. Mixed models examined changes in accelerometer-measured overall time spent in sedentary, light and moderate-to-vigorous physical activity (MVPA); accumulated sedentary and MVPA bouts; and number of MVPA bouts and interruptions in sedentary time.

RESULTS: Overall sedentary time decreased while overall light activity increased across all intervention groups but neither significantly so. The light exercise intervention group reduced their MVPA minutes (-8.22, 95% CI: -16.44, -0.01), time in MVPA bouts (-8.44, 95% CI: -14.27, -2.62), and number of activity bouts (-0.43, 95% CI: -0.77, -0.09). The moderate exercise intervention group reduced the time in MVPA bouts (-6.27, 95% CI: -11.71, -0.82) and number of sedentary interruptions (-5.79, 95% CI: -9.11, -2.46). No changes were observed for the vigorous exercise intervention group.

CONCLUSIONS: On the whole, participating in a structured exercise intervention did not lead people who are affected by depression to significantly reduce their overall light physical activity nor to increase their sedentary time. Participation in the light and moderate exercise intervention programs was associated with reductions in overall MVPA, but this was not evident for the vigorous exercise intervention program.
