The focus of this study was to describe program exposure across three intervention groups from a randomised trial (RT) comparing traditional face-to-face, internet-mediated (combined internet plus face-to-face), and internet-only program delivery. Methods Baseline and immediately post-intervention survey data, and exposure rates from participants that commenced the RT were included (n = 192). Exposure was defined as either face-to-face attendance, website usage, or a combination of both for the internet-mediated group. Characteristics of participants who were exposed to at least 75% of the program material were explored. Descriptive analysis and logistical regression were used to examine differences between groups for program exposure. Results All groups showed decrease in program exposure over time. Differences were also observed (χ2 = 10.37, p < 0.05), between intervention groups. The internet-mediated (OR = 2.4, 95% CI 1.13–5.1) and internet-only (OR = 2.96, 95% CI 1.38–6.3) groups were more likely to have been exposed to at least 75% of the program compared to the face-to-face group. Participants with high physical activity self-efficacy were 1.82 (95% CI 1.15–2.88) times more likely to have been exposed to 75% of the program, and those allocated to the face-to-face group were less likely to have attended 75% of the face-to-face sessions if they were classified as obese (OR = 0.21 95% CI 0.04–0.96). Conclusion These results suggest that the internet groups were as effective as the face-to-face delivery mode in engaging participants in the program material. However, different delivery methods may be more useful to different sub-populations. It is important to explore which target groups that internet-based programs are best suited, in order to increase their impact.Published versio

An investigation of patterns of children's sedentary and vigorous physical activity throughout the week.

BACKGROUND: Participation in higher intensity activity (i.e. vigorous physical activity [VPA]) appears more consistently associated with lower adiposity, unfortunately little is known about the nature and patterns of VPA participation in children. OBJECTIVE: To examine the volume and patterns of vigorous and sedentary activity during different segments of the week (weekend, school-based and out-of-school). We also investigated differences by sex, socioeconomic status (SES) and weight status. DESIGN: A cross-sectional study including 1568 UK children aged 9-10 years. OUTCOME MEASURES: Sedentary activity (mins), total activity (counts/min) and VPA (mins) were measured by accelerometry. Using a series of 2 level mixed effects linear regression models we tested differences across the segmented week (school time [0900-1500] vs. out-of-school time [0700-0900 & 1500-2100]; and weekday vs. weekend); all models were adjusted for sex, weight status (gender- and age-specific body mass index [BMI] cut points), SES, age and accelerometer registered wear time. RESULTS: Boys and girls accumulated higher VPA out-of-school compared to during school (boys mean ± SD 16.9 ± 9.6 vs 12.6 ± 5.8; girls, 13.1 ± 7.7 vs 8.2 ± 4.0, both p 0.05). Less time was spent sedentary on weekdays compared to weekends (p < 0.001). Although boys were more physically active and girls accumulated more sedentary time, the overall pattern in which their physical activity intensity varied across the various day segments was similar when stratified by weight status and SES; and large volumes of sedentary time were observed each hour across the day. CONCLUSIONS: The promotion of VPA during the weekend may hold the greatest promise for increasing VPA. Interventions aimed at increasing physical activity in 9-10 year old children should aim to target all children independent of sex, SES or weight status.RIGHTS : This article is licensed under the BioMed Central licence at http://www.biomedcentral.com/about/license which is similar to the 'Creative Commons Attribution Licence'.

Effects of antiplatelet therapy on stroke risk by brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases: subgroup analyses of the RESTART randomised, open-label trial

Background Findings from the RESTART trial suggest that starting antiplatelet therapy might reduce the risk of recurrent symptomatic intracerebral haemorrhage compared with avoiding antiplatelet therapy. Brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases (such as cerebral microbleeds) are associated with greater risks of recurrent intracerebral haemorrhage. We did subgroup analyses of the RESTART trial to explore whether these brain imaging features modify the effects of antiplatelet therapy

A comparison of mature male and female nursing students course-related family and financial problems

Australia has witnessed a policy-led drive to widen access gates to undergraduate nurse education. In nursing education this has meant a move from recruiting primarily young female school-leavers to increased numbers of older women and to a lesser extent older men entering nurse education. Mature women generally choose to enter nursing because of the ease of entry into less restrictive nursing education programs. At Central Queensland University mature age students constitute 40 to 60% of entrants into the undergraduate nursing program. Previous studies indicate that mature students experience particular problems due to the requirements of nursing courses and in parallel with other disciplines problems related to the costs of undertaking higher education. This paper presents the findings from the Australian arm of an international study of mature student nurses. The study was a postal survey of mature students (N=118) undertaking undergraduate education at Central Queensland University. Data offers some support for the notion that course related problems impact differently on female and male students. The implications of the findings for funding policy and curriculum design will be discussed

Physical activity, cardiorespiratory fitness, and the metabolic syndrome in youth

The metabolic syndrome is defined as the coexistence of multiple cardiovascular and diabetes risk factors, the prevalence of which has increased dramatically in adult populations in the last decades. More recently, the same cluster of metabolic risk factors has also been recognized in children and adolescents. Epidemiological evidence suggests that high levels of cardiorespiratory fitness (CRF) and physical activity are associated with a favorable metabolic risk profile in adults. However, in youth the role of these factors is less clear. Therefore, the purpose of this mini-review is to examine the recent evidence between objectively measured habitual physical activity and CRF with clustered metabolic risk in youth. In general, it appears that both physical activity and CRF are separately and independently associated with metabolic risk factors in youth, possibly through different causal pathways. Further research is necessary to quantify how much physical activity is needed to prevent the metabolic syndrome and the diseases with which it is associated. Public health approaches that encourage increased physical activity and reduce sedentary behaviors may prove useful in reducing the population burden associated with metabolic risk

A comparative study of the course-related family and financial problems of mature nursing students in Scotland and Australia

This study reports a comparative survey of mature students undertaking pre-registration undergraduate nursing education in Australia and Scotland. The study aimed to explore comparisons between the course-related and course-related financial difficulties faced by mature students in two very different educational and funding systems. Financial stress is a predictor of both physical and mental health problems. A similar pattern of course-related problems were reported by both Australian and Scottish students with the exception that Scottish students experienced more problems with childcare and caring for elderly relatives. Course-related problems may be inherent in the nature of undergraduate nursing education although the relatively time-intensive nature of Scottish curricula may explain the childcare and elderly relatives difference. Scottish students reported higher overall financial related problems but Australian students reported more problems with funding placements. These findings have implications for both curriculum designers and policy makers
