Are young children with asthma more likely to be less physically active?

Previous research suggests that children who experience asthma may be less physically active; however, results have been inconclusive. This study aimed to investigate whether the presence of asthma or wheeze is associated with lower physical activity levels in children, and whether sex, body mass index or earlier asthma or wheeze status modifies the association. This study was conducted in 391 HealthNuts participants in Melbourne, Australia. Asthma and wheeze data were collected via questionnaire at age 4 and 6, and physical activity was measured through accelerometry. Using adjusted linear regression models, the cross-sectional and longitudinal associations were investigated. There was no evidence of a difference in time spent in moderate-to-vigorous physical activity (MVPA) at age 6years between children with and without asthma at age 4; children with asthma spent 8.3minutes more time physically active per day (95% CI: -5.6, 22.1, P=.24) than children without asthma. Similar results were seen for children with current wheeze (5.8minutes per day more, 95% CI: -5.9, 17.5, P=.33) or ever wheeze or asthma (7.7minutes per day more, 95% CI: -4.8, 20.2, P=.23) at age 4years. Comparable null results were observed in the cross-sectional analyses. Interaction with BMI could not be assessed; however, previous asthma or wheeze status and sex were not found to modify these associations. This analysis found no evidence of asthma hindering physical activity in these young children. These results are encouraging, as they indicate that the Australian asthma and physical activity public health campaigns are being effectively communicated and adopted by the public.

Profile of blood pressure and glycemic responses after interval exercise in older women attending (in) a public health physical activity program

Backgroundand purpose: Interval exercise causes a positive impact on health status. Our aim was to evaluate the effects of a feasible and low-cost interval exercise on blood pressure and glycemic responses in people with controlled systemic arterial hypertension. MethodsThirteen women with hypertension (HG; age: 60.2 ± 2.8 years) and 11 without hypertension (CG; age: 54.4 ± 3.8 years) were recruited. Groups performed one session of interval exercise with elastic resistance (10 series of 1:1 min/effort:rest). ResultsThere were slight reductions of absolute systolic blood pressure values for HG at 10, 30, and 60 min (4, 9, and 8 mmHg, respectively) at post-compared to pre-exercise. Glycemia was reduced (respectively, 17.6%, 17.6%, 19.4%, and 23.1%; p < 0.05) at pre-exercise vs. 0 min and 10, 30, and 60 min post-exercise for the HG. ConclusionA single session of a feasible and low-cost interval exercise modifies and promotes significant clinical effects in blood pressure and glycemic levels in female older adults with and without hypertension.

Systematic review of the prospective association of daily step counts with risk of mortality, cardiovascular disease, and dysglycemia

BackgroundDaily step counts is an intuitive metric that has demonstrated success in motivating physical activity in adults and may hold potential for future public health physical activity recommendations. This review seeks to clarify the pattern of the associations between daily steps and subsequent all-cause mortality, cardiovascular disease (CVD) morbidity and mortality, and dysglycemia, as well as the number of daily steps needed for health outcomes.MethodsA systematic review was conducted to identify prospective studies assessing daily step count measured by pedometer or accelerometer and their associations with all-cause mortality, CVD morbidity or mortality, and dysglycemia (dysglycemia or diabetes incidence, insulin sensitivity, fasting glucose, HbA1c). The search was performed across the Medline, Embase, CINAHL, and the Cochrane Library databases from inception to August 1, 2019. Eligibility criteria included longitudinal design with health outcomes assessed at baseline and subsequent timepoints; defining steps per day as the exposure; reporting all-cause mortality, CVD morbidity or mortality, and/or dysglycemia outcomes; adults ≥18 years old; and non-patient populations.ResultsSeventeen prospective studies involving over 30,000 adults were identified. Five studies reported on all-cause mortality (follow-up time 4–10 years), four on cardiovascular risk or events (6 months to 6 years), and eight on dysglycemia outcomes (3 months to 5 years). For each 1000 daily step count increase at baseline, risk reductions in all-cause mortality (6–36%) and CVD (5–21%) at follow-up were estimated across a subsample of included studies. There was no evidence of significant interaction by age, sex, health conditions or behaviors (e.g., alcohol use, smoking status, diet) among studies that tested for interactions. Studies examining dysglycemia outcomes report inconsistent findings, partially due to heterogeneity across studies of glycemia-related biomarker outcomes, analytic approaches, and sample characteristics.ConclusionsEvidence from longitudinal data consistently demonstrated that walking an additional 1000 steps per day can help lower the risk of all-cause mortality, and CVD morbidity and mortality in adults, and that health benefits are present below 10,000 steps per day. However, the shape of the dose-response relation is not yet clear. Data are currently lacking to identify a specific minimum threshold of daily step counts needed to obtain overall health benefit.

AB1320-HPR THE ASSOCIATION BETWEEN PHYSICAL ACTIVITY AND CARDIORESPIRATORY FITNESS IN PATIENTS WITH RHEUMATOID ARTHRITIS AND HIGH CARDIOVASCULAR RISK

Background:Rheumatoid arthritis (RA) is associated with increased risk of cardiovascular disease (CVD) disease and CV mortality1. High values of cardiorespiratory fitness (CRF) are protective against CVD and CV mortality2. Physical activity levels in patients with RA are low. Knowledge on whether physical activity is associated with CRF in patients with RA and high CV risk is scarce. This knowledge is important because improving the level of physical activity could improve CRF and lower CV risk in this group of patients with RA and high CV risk. However, it is unclear whether physical activity is associated with CRF in this group of patients. This study presents the preliminary results at baseline of the association of physical activity with CRF from an ongoing pilot study aimed at improving CRF through exercise therapy in patients with RA and high CV risk.Objectives:To determine (i) the level of physical activity in patients with RA and high CV risk and (ii) whether physical activity is associated with CRF in patients with RA and high CV risk.Methods:Patients with RA and high CV risk participated in this pilot study. Increased 10-year risk of CV mortality was determined by using the Dutch SCORE-table. Anthropometrics and disease characteristics were collected. Physical activity was assessed with an Actigraph accelerometer to determine the number of steps and intensity of physical activity expressed in terms of sedentary, light, and moderate-to-vigorous time per day. Participants wore the accelerometer for seven days. A minimum of four measurement days with a wear time of at least 10 hours was required. The VO2max measured with a graded maximal exercise test was used to determine the CRF. Pearson correlation coefficients were calculated for the associations between the different measures of physical activity and VO2max. For the variables that were associated, linear regression analysis was carried out, with pain and disease activity as possible confounders.Results:Thirteen females and five males were included in the study. The mean age was 66.5 (± 15.0) years. Only 22% of the patients met public health physical activity guidelines for the minimal amount of 150 minutes a week. The mean step count was 6237 (± 2297) steps per day and mean moderate-to-vigorous physical activity time was 16.50 (± 23.56) minutes per day. The median VO2max was 16.23 [4.63] ml·kg-1·min-1, which is under the standard. Pearson correlations showed a significant positive association for step count with VO2max. No associations were found for sedentary, light, and moderate-to-vigorous physical activity with VO2max. The significant association between step count and VO2max(p = 0.01) was not confounded by disease severity and pain.Discussion:Since better CRF protects against CVD, increasing daily step count may be a simple way to reduce the risk of CVD in patients with RA and high CV risk. However, these results need to be confirmed in a larger study group. Future research should investigate if improving daily step count will lead to better CRF levels and ultimately will lead to a reduction in CV risk in patients with RA and high CV risk.Conclusion:Physical activity levels of patients with RA and high CV risk do not meet public health requirements for physical activity criteria and the VO2max was under the standard. Step count is positively associated with CRF.

Enjoyment and acceptability of different exercise modalities to improve bone health in young adult women.

Osteoporosis presents a serious public health issue and physical activity is recognised as the most effective modifiable risk factor for the condition. The reasons behind physical activity participation, however, are complex. We therefore aimed to explore the experiences related to a bone-targeted exercise intervention, determine enjoyment and acceptability of each exercise mode, and identify barriers and facilitators to osteogenic exercise for young adult women. The present study was conducted within the Osteoporosis Prevention Through Impact and Muscle-loading Approaches to Exercise (OPTIMA-Ex) trial, a three-arm RCT comparing musculoskeletal outcomes from two supervised, high-intensity, exercise programs (impact and resistance training) with an unsupervised low-intensity exercise control. A mixed-methods approach was used, including quality of life and physical activity enjoyment questionnaires and qualitative analysis of semi-structured interviews. All groups had improvements in the 'mental health' domain of the quality of life measure; however, the two supervised exercise groups had greater levels of physical activity enjoyment. The qualitative analysis revealed that overall the trial activities were positively, yet the two supervised groups had 'richer' exercise experiences. Motivations for participation, barriers to physical activity and desired continuation of participation differed between all three groups. Findings suggest that bone-targeted exercise interventions for young adult women must address perceived time demands and environmental barriers to participation in order to maximise compliance and adherence. SO WHAT?: As physical activity is the most effective lifestyle strategy to improve bone health and young adulthood an important window for its augmentation, increasing convenience, accessibility and understanding of osteoporosis preventative behaviours in this demographic is vital.

Resistance Exercise for the Prevention and Treatment of Pediatric Dynapenia

Temporal trends of youth muscular fitness (i.e., muscular strength, muscular power and local muscular endurance) indicate that contemporary children and adolescents are weaker and slower than previous generations. Consequently, this generation of millennials appear to be just as vulnerable as older adults to the inevitable consequences of muscle disuse and neuromuscular dysfunction. The modern-day construct of pediatric dynapenia describes an identifiable and treatable condition in youth characterized by low levels of muscular strength and power and consequent physical and psychosocial limitations not caused by neurologic or muscular disease. An interaction of modifiable physical and psychosocial factors can influence the development and progression of pediatric dynapenia. Without structured interventions that target strength deficits and build strength reserves in a supporting environment, the divergence in performance between weaker and stronger children may persist into adolescence because weaker youth may be unable to break through a so-called strength barrier. Regular participation in a well-designed youth resistance training program provides an opportunity for youth to enhance their health and fitness while acquiring the physical skills and behaviors that support an active lifestyle. New insights have highlighted the importance of initiating strength-building interventions early in life to optimize performance gains in other important components of physical fitness. Developmentally appropriate resistance training should be integrated into school- and community-based youth fitness programs and strength-building activities should take a more prominent position in public health physical activity recommendations for children and adolescents.

High sedentary behaviour and low physical activity levels at 12 months after cardiac rehabilitation: A prospective cohort study.

International cardiac rehabilitation guidelines recommend that participants meet public health physical activity guidelines. Few studies have objectively measured how much time cardiac rehabilitation participants spend in physical activity and sedentary behaviour, particularly over the long term. The aim of this study was to objectively assess physical activity and sedentary behaviour of cardiac rehabilitation participants over 12 months and determine whether they met the public health physical activity and sedentary behaviour guidelines. Cardiac rehabilitation participants with coronary heart disease were recruited in a prospective cohort study (n=72). Participants wore an ActiGraph ActiSleep accelerometer for 7 consecutive days at baseline, 6 weeks, and 6 and 12 months to assess daily minutes of moderate-to-vigorous physical activity and sedentary behaviour (<100 counts/min). Other outcomes collected were self-reported physical activity and sedentary behaviour, body mass index, waist-to-hip ratio, lipid profile, blood glucose level, quality of life, exercise capacity, anxiety and depression. By intent-to-treat analysis, during the 6-week cardiac rehabilitation program, participants increased their light physical activity (P<0.01), which was maintained up to 12 months. Moderate-to-vigorous physical activity and sedentary behaviour did not change during the 6-week cardiac rehabilitation program but did improve over 6 months (sedentary behaviour decreased [P<0.001], moderate-to-vigorous physical activity increased [P<0.05]), which was maintained up to 1 year. Completion of moderate-to-vigorous physical activity in 10-min bouts did not change over 12 months, nor did the proportion of participants meeting physical activity guidelines (15-21%). Sedentary behaviour remained high throughout (11 hr/day). Most cardiac rehabilitation participants did not meet the physical activity guidelines during and after a 6-week program up to 12 months. Reducing sedentary behaviour may be a more achievable first-line strategy for cardiac patients, moving participants along the energy expenditure continuum, aiming to increase their physical activity levels over the medium to long term.

The Demise of an Australian Physical Activity Alliance.

Physical activity health promotion coalitions are uncommon but important for beneficial collective impact on public health. The authors sought to obtain the viewpoints of member organizations of an Australian physical activity alliance, the National Physical Activity Alliance. The authors conducted an online survey regarding member agenda, commitment, and vision for the alliance. Questions were mostly open ended (eg,"What are the 3 areas of priority related to physical activity that you would like The Alliance to focus on?"). A total of 11 Australian organizations involved in physical activity public health (eg,the nongovernment organization Alzheimer's Australia and the professional fitness association Fitness Australia). 82% of members responded to the survey. Member programs and goals were diverse and overlapping. There was agreement among members that the main priority area for alliance focus was a national exercise referral scheme. Barriers for members achieving their own goals as well as alliance goals focused on governmental issues, including inadequate government funding for physical activity public health. This novel survey highlights the promise and difficulties of a physical activity coalition, with the difficulties, namely lack of governmental funding, resulting in a stagnation of the alliance's activities since the study was carried out.

Cuantificación de los niveles de actividad física a través de podómetros en las clases de Educación Física: Un estudio piloto

&lt;p&gt;La inactividad física durante los primeros años de vida está reconocida actualmente como un factor importante en el incremento de los niveles de obesidad y de otros trastornos médicos graves que se observan en los escolares europeos. Los escolares pasan una gran parte de su tiempo en el entorno escolar y éste debería convertirse en un entorno propicio para promocionar la actividad física. A nivel mundial, las pautas de actividad física para la salud pública incluyen un énfasis especial en poblaciones de niños (típicamente 6-11 años) y adolescentes (típicamente 12-19 años). Las directrices existentes normalmente se expresan en términos de frecuencia, el tiempo y la intensidad de la conducta. Sin embargo, con el avance tecnológico han aparecido nuevas alternativas para medir los niveles de actividad física, destacando el uso de los acelerómetros y podómetros en la investigación y en la práctica como una aproximación razonable del volumen de la actividad física diaria. El presente estudio tiene como objetivo medir la cantidad de actividad física realizada en las clases de educación física. La muestra quedó compuesta por 70 escolares (41 niños y 29 niñas) con un rango de edad de 10 y 12 años en una escuela de la Región de Murcia. Un podómetro fue utilizado para cuantificar los niveles de actividad física. Se analizaron dos sesiones de la Unidad Didáctica Juegos y Deportes Alternativos. Los resultados mostraron una media de pasos/día de 3.318 (3.467,3 pasos/día en niños y 3.107,2 pasos/día en niñas). Esta cantidad representa el 20.1% y el 28.85% de la cantidad total recomendada en función del límite del rango tenido en cuenta (11.000 y 16.500 pasos/día).&lt;/p&gt;

Workforce capacity to address obesity: a Western Australian cross-sectional study identifies the gap between health priority and human resources needed.

BackgroundThe disease burden due to poor nutrition, physical inactivity and obesity is high and increasing. An adequately sized and skilled workforce is required to respond to this issue. This study describes the public health nutrition and physical activity (NAPA) practice priorities and explores health managers and practitioner’s beliefs regarding workforce capacity to deliver on these priorities.MethodsA workforce audit was conducted including a telephone survey of all managers and a postal survey of practitioners working in the area of NAPA promotion in Western Australia in 2004. Managers gave their perspective on workforce priorities, current competencies and future needs, with a 70 % response rate. Practitioners reported on public health workforce priorities, qualifications and needs, with a 56 % response rate.ResultsThe top practice priorities for managers were diabetes (35 %), alcohol and other drugs (33 %), and cardiovascular disease (27 %). Obesity (19 %), poor nutrition (15 %) and inadequate physical activity (10 %) were of lower priority. For nutrition, managers identified lack of staff (60.4 %), organisational and management factors (39.5 %) and insufficient financial resources (30.2 %) as the major barriers to adequate service delivery. For physical activity services, insufficient financial resources (41.7 %) and staffing (35.4 %) and a lack of specific physical activity service specifications (25.0 %) were the main barriers. Practitioners identified inadequate staffing as the main barrier to service delivery for nutrition (42.3 %) and physical activity (23.3 %). Ideally, managers said they required 152 % more specialist nutritionists in the workforce and 131 % specialists for physical activity services to meet health outcomes in addition to other generalist staff.ConclusionHuman and financial resources and organisational factors were the main barriers to meeting obesity, and public health nutrition and physical activity outcomes. Services were being delivered by generalists rather than specialists, which may reduce service effectiveness. Although conclusions from this research need to take into account the fact that the audit was conducted in 2004, the findings suggest that there was a need to equip health services with an adequately skilled workforce of sufficient capacity to deliver an effective public health response to the obesity epidemic, particularly addressing poor nutrition and physical inactivity.

Effects On Cardiovascular Risk Factors Of Three 48-week Community-based Exercise Interventions

A sedentary lifestyle is associated with cardiovascular disease (CVD). Blood pressure (BP) and blood lipids (cholesterols) are key mediators of CVD. A substantial body of evidence demonstrates reduced CVD risk following systematic physical activity (PA). Despite this evidence, CVD continues to rise, and public health PA initiatives often fail to demonstrate clinically relevant effects. In short, laboratory efficacy often fails to translate into real-world effectiveness. PURPOSE: We investigated the effectiveness of three physical activity interventions. We did so using a Phase-IV clinical trial model, in which all treatments were administered in uncontrolled community settings, and in which all interventions and measures were delivered by, and conducted by, community health centre staff. METHODS: Participants were sedentary individuals receiving no medication to reduce CVD risk (n=238, age 43±5 years). Participants selected a PA or exercise (EX) pathway. Those who selected PA were randomised to either fitness centre based PA counselling delivered by an exercise professional (PAC) or a wait-list control condition (CONT). Those who selected EX were randomised to either a structured exercise program (STRUC) or unstructured fitness centre use (FREE). Measures were mean arterial pressure (MAP: mmHg) estimated using the formula Diastolic Blood Pressure (BP) + (0.33 x (Systolic BP – Diastolic BP)), and total cholesterol (TC: mmol/L). Measures were taken at baseline and 48 weeks. Data were analysed using paired-sample t-tests. RESULTS: Data analysis for cholesterol indicated a small but statistically significant increase in TC in CONT (M=0.8%, SD=0.5, p = .005). TC was however approximately equivalent to baseline in PAC and FREE and reduced, although not significantly, in STRUC. Data for blood pressure indicated a statistically significant decrease in MAP in STRUC (M=2.5%, SD=8.3, P = .004). MAP was reduced, although not significantly, in all other treatments and CONT. CONCLUSIONS: Data suggest that over 48 weeks, all forms of exercise might be effective in offsetting increases in total cholesterol associated with inactivity. Furthermore, a structured exercise programme might be more effective than either unstructured exercise or physical activity counselling in reducing mean arterial blood pressure.

Effects On Aerobic Capacity Of Three 48-week Community-based Exercise Interventions

A sedentary lifestyle is associated with cardiovascular disease (CVD). A substantial and compelling body of evidence demonstrates reduced CVD risk following systematic physical activity (PA). Despite this evidence, CVD continues to rise, and public health PA initiatives appear to be failing to demonstrate clinically relevant effects. PURPOSE: A core component of cardiovascular health is the ability to utilise oxygen, termed ‘oxygen uptake’ or VO2. We investigated the effectiveness of three physical activity interventions on oxygen uptake. We did so using a Phase-IV clinical trial model, in which all treatments were administered in uncontrolled community settings, and in which all interventions and measures were delivered by, and conducted by, community health centre staff. METHODS: Participants were sedentary individuals receiving no medication to reduce CVD risk (n=238, age 43±5 years). Participants selected a PA or exercise (EX) pathway. Those who selected PA were randomised to either fitness centre based physical activity counselling delivered by an exercise professional (PAC) or a wait-list control condition (CON). Those who selected EX were randomised to either a structured exercise program (STRUC) or unstructured fitness centre use (FREE). The dependent measure was predicted maximum oxygen uptake (VO2 max; ml/kg/min), measured using the COSMED Fitmate. Measures were taken at baseline and 48 weeks. RESULTS: Repeated measures ANOVA indicated no statistically significant difference between treatments (F [3,215] = 1.173, p = .321), and paired-sample t-tests indicated no significant pre-post effects for any treatment. When data were grouped using a quartile split by baseline VO2 max however, repeated measures ANOVA indicated significant differences between groups (F [3,215] = −6.1, p < .001), specifically that whilst in the highest two quartiles VO2 max was reduced (M = -2.7, SD = 7.0, p=.05 and M = -2.6, SD = 6.0, p=.008 respectively), and no significant change was observed in the third quartile (M = -0.1, SD = 5.0, p = .89), in the lowest quartile, VO2 max was significantly increased (M = 4.1, SD = 6.6, p < .001). CONCLUSIONS: Data suggest that in terms of VO2, treatments in the current study were more effective with the least fit participants at baseline, and actually counter-productive for the most fit.

Exploring the Feasibility of a Broad-Reach Physical Activity Behavior Change Intervention for Women Receiving Chemotherapy for Breast Cancer: A Randomized Trial.

Facilitating healthy levels of physical activity (PA) during chemotherapy is important for the psychosocial and physical health of breast cancer survivors. The primary objective of this feasibility study was to examine the effects of a broad-reach PA behavior change intervention among women with breast cancer receiving adjuvant chemotherapy. Breast cancer patients receiving adjuvant chemotherapy (N = 95) were randomly assigned to receive a PA resource kit consisting of tailored print materials and a step pedometer (intervention) or a standard public health PA recommendation (standard recommendation). The primary outcome was daily pedometer steps. Secondary outcomes were self-reported light, moderate, and vigorous intensity PA, total moderate-to-vigorous PA, and sedentary time. Assessments were conducted before and after adjuvant chemotherapy. Attrition was 19% (17 of 95). Intervention patients wore their step pedometer for 85 days (range, 35-144 days; SD = 26.4) for a 95% adherence rate. Analyses of covariance suggested that the intervention was not statistically superior to standard recommendation for daily average pedometer steps (-771; 95% CI = -2024 to 482; P = 0.22), total MVPA minutes (-4; 95% CI = -62 to 570; P = 0.90), or sedentary time (+160; 95% CI = -186 to 506; P = 0.42). This broach-reach and low intensive intervention was not more effective for promoting PA in breast cancer patients receiving chemotherapy than providing the standard public health guidelines for PA. Achieving physical activity behavior change during adjuvant breast cancer chemotherapy may require some level of supervised physical activity or more intensive (e.g., face-to-face, supervised) interventions.

We Are All Ballooning: Multimedia Critical Discourse Analysis of ‘Measure Up’ and ‘Swap It, Don’t Stop It’ Social Marketing Campaigns

Treatment, behavioral, and psychosocial components of cardiovascular disease risk among survivors of childhood and young adult cancer.

The incidence of childhood, adolescent, and young adult (AYA) cancers have been increasing since 1975.[1][1] In 2014, an estimated 10 450 and 5330 new cancers will be diagnosed among children aged birth–14 and adolescents aged 15 to 19 years old, respectively.[2][2] For young adults aged 20 to 34

Using the RE-AIM framework to evaluate physical activity public health programs in México.

BackgroundPhysical activity (PA) public health programming has been widely used in Mexico; however, few studies have documented individual and organizational factors that might be used to evaluate their public health impact. The RE-AIM framework is an evaluation tool that examines individual and organizational factors of public health programs. The purpose of this study was to use the RE-AIM framework to determine the degree to which PA programs in Mexico reported individual and organizational factors and to investigate whether reporting differed by the program’s funding source.MethodsPublic health programs promoting PA were systematically identified during 2008–2013 and had to have an active program website. Initial searches produced 23 possible programs with 12 meeting inclusion criteria. A coding sheet was developed to capture behavioral, outcome and RE-AIM indicators from program websites.ResultsIn addition to targeting PA, five (42%) programs also targeted dietary habits and the most commonly reported outcome was change in body composition (58%). Programs reported an average of 11.1 (±3.9) RE-AIM indicator items (out of 27 total). On average, 45% reported reach indicators, 34% reported efficacy/effectiveness indicators, 60% reported adoption indicators, 40% reported implementation indicators, and 35% reported maintenance indicators. The proportion of RE-AIM indicators reported did not differ significantly for programs that were government supported (M = 10, SD = 3.1) and programs that were partially or wholly privately or corporately supported (M = 12.0, SD = 4.4).ConclusionWhile reach and adoption of these programs were most commonly reported, there is a need for stronger evaluation of behavioral and health outcomes before the public health impact of these programs can be established.Electronic supplementary materialThe online version of this article (doi:10.1186/s12889-015-1474-2) contains supplementary material, which is available to authorized users.

Adolescents and young adult cancer survivors: exercise habits, quality of life and physical activity preferences.

Given the decades of survivorship for adolescent and young adult (AYA) cancer survivors, it is important to promote behaviours that enhance physical and mental well-being and quality of life (QoL). The purpose of this study was to explore the exercise programming preferences and information needs of AYA survivors and to examine the impact of a cancer diagnosis on physical activity behavior and QoL. Participants aged 15-25 years at time of diagnosis and referred to a specialist AYA cancer service between January 2008 and February 2012 were recruited. Eligible participants were mailed a self-administered questionnaire assessing demographic and disease-related information, physical activity levels over time and exercise information preferences. QoL was measured using the Assessment of Quality of Life-6D (AQoL-6D). Seventy-four (response rate 52 %) participants completed the questionnaire. The mean age was 23 years with 54 % female, with prevalent diagnoses included hematological malignancy (45 %) and sarcoma (24 %). Results indicated a significant reduction in the average minutes of physical activity post diagnosis (p =< 0.001) and during treatment (p = < 0.001). AYA who met public health physical activity guidelines (n = 36) at questionnaire completion had significantly higher QoL than those not meeting the guidelines (n = 38) (median (Mdn) = 0.87, interquartile range (IQR) = 0.73 to 0.98 and Mdn = 0.81, IQR = 0.57 to 0.93, respectively; p = 0.034). Most participants wanted exercise information at some point after diagnosis (85 %) but many did not receive any information (45 %). Findings suggest that AYA with cancer experience a significant impact on physical activity levels and QoL. Moreover, survivors experience considerable difficulty returning to premorbid levels of activity. Our study suggests that interventions promoting physical activity and healthy lifestyle behaviours would be well accepted within this population and may be essential to improve their long-term health and QoL during survivorship.

Objectively measured physical activity in European children: the IDEFICS study.

To provide sex- and age-specific percentile values for levels of physical activity (PA) and sedentary time of European children aged 2.0-10.9 years from eight European countries (Sweden, Germany, Hungary, Italy, Cyprus, Spain, Belgium and Estonia). Free-living PA and sedentary time were objectively assessed using ActiGraph GT1M or ActiTrainer activity monitors in all children who had at least 3 days' worth of valid accelerometer data, with at least 8 h of valid recording time each day. The General Additive Model for Location Scale and Shape was used for calculating percentile curves. Reference values for PA and sedentary time in the European children according to sex and age are displayed using smoothed percentile curves for 7684 children (3842 boys and 3842 girls). The figures show similar trends in boys and girls. The percentage of children complying with recommendations regarding moderate-to-vigorous physical activity (MVPA) is also presented and varied considerably between sexes and country. For example, the percentage of study participants who were physically active (as assessed by MVPA) for 60 or more minutes per day ranged from 2.0% (Cyprus) to 14.7% (Sweden) in girls and from 9.5% (Italy) to 34.1% (Belgium) in boys. This study provides the most up-to-date sex- and age-specific reference data on PA in young children in Europe. The percentage compliance to MVPA recommendations for these European children varied considerably between sexes and country and was generally low. These results may have important implications for public health policy and PA counselling.
