Improving the efficiency of modelling complex physical activity data using longitudinal compositional data analysis
Physical activity (PA) data are often objectively collected using an accelerometer worn by the participant, with data collected over a pre-specified period. PA has historically been summarised as a single numerical measure, often the number of minutes spent in moderate-to-vigorous PA, disregarding …

Recognizing cardiovascular disease patterns with machine learning using NHANES accelerometer determined physical activity data
The relationship between physical activity (PA) and cardiovascular disease (CVD) is well established; however, questions about the appropriate dose of PA to reduce CVD risk still remain (Blair, LaMonte, & Nichaman, 2004; Pate et al., 1995). The optimal dose and the effects of intensity, duration, …

The use of publicly available physical activity data: A pilot study into the reliability of the data flow from GPS portable fitness devices to the Internet
… investigating relationships between health and physical activity commonly use self-reports and questionnaires to acquire information. The reliability and validity of much of this subjective data has been questioned. The availability and affordability of a range of portable fitness devices (PFD), …

Food Security and Physical Activity in Individuals Living With HIV/AIDS in Rural Appalachia
… study examined household food security (HFS) and physical activity (PA among individuals living with HIV/AIDS living in rural Appalachia (West Virginia, Appalachian Ohio, Kentucky, and Pennsylvania). Participants (n = 82) completed an online or paper survey that included validated measures of HFS …

Time Efficiency in Computer Assisted Direct Observation of Physical Activity using SOFIT
Having valid and reliable methods for assessing physical activity levels is critical to understanding physical activity patterns. Direct observation is a widely used technique for obtaining contextually rich data on physical activity levels in physical education classes. One major limitation of …

Relationship of dietary antioxidant intake, antioxidant serum capacity, physical activity and inflammation in breast cancer survivors and individuals without a history of cancer
Background: Dietary and serum antioxidants and physical activity can effect inflammation, which is associated with breast cancer risk and recurrence. This study investigated the relationship between diet, serum antioxidant capacity, physical activity, and inflammation in breast cancer survivors and …

Dietary assessment, ultra-processed food consumption, and adiposity in four countries of South Asia
… from the paucity of detailed food consumption data and the lack of readily available dietary assessment tools capable of collecting individual-level dietary intake data at scale. In my PhD, I aimed to – 1) operationalise and assess the validity of a 24-hour dietary recall instrument for South …

The development and evaluation of a novel online tool for assessing dietary intake and physical activity levels for use in adult populations
The Synchronised Nutrition and Activity Program for Adults (SNAPA™) was developed to address the need for accurate, reliable, feasible, inexpensive and low burden methods for measuring diet and physical activity behaviours in free-living adult populations. Usability testing (n=5) identified a …

Neuromuscular Adaptations to Training in Children with Cerebral Palsy
Cerebral palsy (CP) is the most common cause of physical disability in children. Children with CP often require lifelong therapy to improve physical mobility or to prevent development of secondary complications. While previous research has investigated the effect of various therapeutic approaches …

Improving our understanding of the influences of the environment on physical activity
Physical activity reduces the risk of many chronic diseases, and much of the population would benefit from being more active. Public health strategies increasingly identify the environment as an important influence on activity and therefore a target for intervention. However, it is difficult to …

Associations between physical activity of older adults and built environment features in and around parks: a Belfast case study
Physical inactivity is a key risk factor for healthy ageing, and older adults are likely to be amongst the most physically inactive. There is now an increased understanding of how built environment factors facilitate physical activity of the population, including that of older adults, which has …

Young people’s active travel in Asia
**Background** The benefits of physical activity have been extensively documented and recognised. In addition to that, numerous studies have demonstrated a clear link between active travel and increased physical activity levels in young people. Active travel also has the potential to reduce air …
