Abstract
Since the early 20th century, it has been known that Vitamin C plays a role in human health and susceptibility to infections. Studies show that for specific population groups, the duration of the common cold can be reduced with increased Vitamin C intake. It has also been shown to reduce the length of stay in intensive care units and use of mechanical ventilation by 8% with administration of 1-3g of Vitamin C daily. This NED Infobite highlights some of the latest research into Vitamin C and the immune system, focusing in particular on infections, ICU stays and need for mechanical ventilation.

Abstract
The exact causes of migraine headaches are still unknown. It seems likely that the aetiology is multi-factorial. This NED Infobite includes studies looking at anti-inflammatory agents such as curcumin and omega-3's, the impacts of optimising Vitamin D and partaking exercise and how targeting overweight and obesity may also reduce the frequency and duration of migraines.

Plain language summary
Regular physical activity is beneficial to children’s physical, social and mental health. However, most children fail to meet the recommended 60+ min of moderate-intensity to vigorous-intensity physical activity every day. The Transform-Us! school-based and home-based intervention was developed to determine the impact of strategies to promote children’s moderate-to-vigorous physical activity versus reduce sedentary behaviour or a combination of these strategies, on behavioural and health outcomes. The main aim of this study was to determine the efficacy of the independent and combined intervention approaches to promoting physical activity and reducing sedentary behaviour on children’s moderate-to-vigorous physical activity and sedentary time after 18 and 30 months compared with usual practice. This study is a 30-month 2×2 factorial design cluster randomised controlled trial delivered in 20 primary schools with additional home intervention components. After recruitment, schools were then randomly allocated to one of four groups. Results show that Transform-Us! had stronger effects on children’s sedentary behaviour than physical activity in both the physical activity (PA) and sedentary behaviour (SB) interventions, and there were beneficial effects on children’s adiposity for both intervention approaches. However, no clear conclusions could be drawn regarding which intervention (PA or SB) had the strongest or more consistent effects on children’s health outcomes. Authors conclude that, based on their findings, government education departments and schools should consider adopting and implementing whole-of-school programmes to promote children’s physical activity and reduce sitting through active pedagogy and supportive social and physical environments at school and home to benefit children’s sedentary time and some markers of cardiometabolic health.
Abstract
OBJECTIVE To test the efficacy of the Transform-Us! school- and home-based intervention on children's physical activity (PA), sedentary behaviour (SB) and cardiometabolic risk factor profiles. METHODS A 30-month 2×2 factorial design cluster randomised controlled trial delivered in 20 primary schools (148 Year 3 classes) in Melbourne, Australia (2010-2012), that used pedagogical and environmental strategies to reduce and break up SB, promote PA or a combined approach, compared with usual practice. Primary outcomes (accelerometry data; n=348) were assessed at baseline, 18 and 30 months. Secondary outcomes included body mass index (BMI) and waist circumference (WC) (n=564), blood pressure (BP) (n=537) and biomarkers (minimum n=206). Generalised linear mixed models estimated the interactive effects of the PA and SB interventions on the outcomes. If there was no interaction, the main effects were assessed. RESULTS At 18 months, there were intervention effects on children's weekday SB (-27 min, 95% CI: -47.3 to -5.3) for the PA intervention, and on children's average day PA (5.5 min, 95% CI: 0.1 to 10.8) for the SB intervention. At 30 months, there was an intervention effect for children's average day SB (-33.3 min, 95% CI: -50.6 and -16.0) for the SB intervention. Children's BMI (PA and SB groups) and systolic BP (combined group) were lower, and diastolic BP (PA group) was higher. There were positive effects on WC at both time points (SB intervention) and mixed effects on blood parameters. CONCLUSIONS The Transform-Us! PA and SB interventions show promise as a pragmatic approach for reducing children's SB and adiposity indicators; but achieving substantial increases in PA remains challenging.

Plain language summary
Overweight and obese older adults are at increased risk for vitamin D deficiency, which is associated with poor metabolic and musculoskeletal health, unfavourable body composition, and attenuated responses to exercise. The aim of this study was to determine whether, compared with placebo, vitamin D3 supplementation (4000 IU/day) taken prior to and during a 12-week exercise program improves physical function, body composition or metabolic health, in overweight or obese older adults with vitamin D deficiency. This study is a 24-week parallel-group, double-blind, placebo-controlled pilot randomised controlled trial. Fifty overweight or obese participants were enrolled for the study, and randomised to either 4000 IU/day of oral vitamin D3 or identical placebo. Results demonstrated that 4000 IU/day vitamin D3 supplementation: - did not affect gait speed when taken with or without exercise, - helped achieve optimal serum 25-hydroxyvitamin D levels and decreased waist circumference (compared with placebo) following multi-modal exercise. - taken alone without exercise reduced stair climb times. However, vitamin D3 supplementation did not have any beneficial effects on other biochemical, body composition or physical function parameters when taken alone or during exercise. Authors conclude that future studies should focus on populations with moderate or severe vitamin D deficiency as they are more likely to experience therapeutic benefits from vitamin D supplementation.
Abstract
PURPOSE Vitamin D supplementation may have non-skeletal health benefits and enhance exercise responsiveness, particularly in those with low vitamin D levels. We determined whether, compared with placebo, vitamin D supplementation taken prior to and during a 12-week exercise program improves physical function, body composition or metabolic health, in overweight and obese older adults with vitamin D deficiency. METHODS Fifty overweight or obese older adults (mean ± SD age: 60 ± 6 years; BMI 30.6 ± 5.7 kg/m2) with vitamin D deficiency (25-hydroxyvitamin D [25(OH)D] < 50 nmol/L) were recruited. Participants were randomly allocated to receive either vitamin D3 (4000 IU/day) or matching placebo for 24 weeks. Between weeks 12 and 24, all participants completed multi-modal exercise three days per week while continuing with vitamin D/placebo. Mean changes in physical function (primary outcome: gait speed), body composition and biochemical parameters at weeks 12 and 24 were compared between groups. RESULTS Vitamin D supplementation, with or without exercise, had no effect on gait speed. From baseline to week 12, vitamin D supplementation increased serum 25(OH)D levels (placebo: 2.5 ± 14.7 nmol/L; treatment: 43.4 ± 18.4 nmol/L; P < 0.001) and reduced stair climb times (placebo: 0.3 ± 1.0 s; treatment: - 0.2 ± 1.0 s; P = 0.046). From 12 to 24 weeks, vitamin D supplementation combined with exercise decreased waist circumference (placebo: 1.3 ± 7.3 cm; treatment: - 3.0 ± 6.1 cm; P = 0.02) and waist-to-hip ratio (placebo: 0.01 ± 0.05; treatment: - 0.03 ± 0.05; P = 0.01) relative to placebo. Vitamin D supplementation, with or without exercise, had no effect on other physical function, body composition or metabolic health outcomes. CONCLUSION Vitamin D supplementation had no effect on most physical function, body composition or metabolic health parameters when taken alone, or during exercise, in overweight or obese older adults with vitamin D deficiency. Vitamin D-related improvements in stair climb times and waist circumference suggest that future trials should explore the effects of vitamin D on muscle power, and its effects on body composition when combined with exercise, in populations with moderate or severe vitamin D deficiency.
