Incorporating a gender lens into nutrition and health-related policies in Fiji: analysis of policies and stakeholder perspectives
Background: Gender equality, zero hunger and healthy lives and well-being for all, are three of the Sustainable Development Goals (SDGs) that underpin Fiji’s National Development Plan. Work towards each of these goals contributes to the reduction of non-communicable diseases (NCDs). There are gender differences in NCD burden in Fiji. It is, however, unclear whether a gender lens could be more effectively included in nutrition and health-related policies. Methods: This study consisted of three components: (i) a policy content analysis of gender inclusion in nutrition and health-related policies (n = 11); (ii) policy analysis using the WHO Gender Analysis tool to identify opportunities for strengthening future policy; and (iii) informant interviews (n = 18), to understand perceptions of the prospects for gender considerations in future policies. Results: Gender equality was a goal in seven policies (64%); however, most focused on women of reproductive age. One of the policies was ranked as gender responsive. Main themes from key informant interviews were: 1) a needs-based approach for the focus on specific population groups in policies; 2) gender-related roles and responsibilities around nutrition and health; 3) what is considered “equitable” when it comes to gender, nutrition, and health; 4) current considerations of gender in policies and ideas for further gender inclusion; and 5) barriers and enablers to the inclusion of gender considerations in policies. Informants acknowledged gender differences in the burden of nutrition-related NCDs, yet most did not identify a need for stronger inclusion of gender considerations within policies. Conclusions: There is considerable scope for greater inclusion of gender in nutrition and health-related policies in Fiji. This could be done by: 1) framing gender considerations in ways that are actionable and inclusive of a range of gender identities; 2) undertaking advocacy through actor networks to highlight the need for gender-responsive nutrition and health-related policies for key stakeholder groups; 3) ensuring that data collected to monitor policy implementation is disaggregated by sex and genders; and 4) promoting equitable participation in nutrition related issues in communities and governance processes. Action on these four areas are likely critical enablers to more gender equitable NCD reduction in Fiji
Reliability of the Elliptical Zone Method of Estimating Body Segment Parameters of Swimmers
Due to the difficulty of measuring forces and torques acting on a swimmer during mid-pool swimming, an inverse dynamics approach is required. Personalised body segment parameter (BSP) data enabling calculation of net forces and torques can be obtained using the elliptical zone method. The purpose of this study was to establish the reliability of estimating BSP data of swimmers by the elliptical zone method with segment outlines being traced manually on a personal computer screen. Five assessors digitised the segment landmarks and traced the body segments from front and side view digital photographs of 11 single arm amputee swimmers. Each swimmer was assessed five times by each of the five assessors. The order was fully randomised. Within assessor variability was less than 5% for the segment centre of mass position of all segments, for segment length except the neck (5.2%), and for segment mass except neck (11.9%), hands (Left: 8.1%; Right: 5.8%) and feet (Left: 7.3%; Right: 7.3%). Analysis of mean variability within and between assessors indicated that between assessor variability was generally as large or larger than within assessor variability. Consequently it is recommended that when seeking personalised BSP data to maximise the accuracy of derived kinetics and sensitivity for longitudinal and bilateral within-subject comparisons the individual should be assessed by the same assessor with mean values obtained from five repeat digitisations. This study established that using the elliptical zone method using E-Zone software is a reliable and convenient way of obtaining personalised BSP data for use in analysis of swimming
Monitoring the impacts of trade agreements on food environments
The liberalization of international trade and foreign direct investment through
multilateral, regional and bilateral agreements has had profound implications
for the structure and nature of food systems, and therefore, for the availability,
nutritional quality, accessibility, price and promotion of foods in different
locations. Public health attention has only relatively recently turned to the links
between trade and investment agreements, diets and health, and there is currently
no systematic monitoring of this area. This paper reviews the available evidence on the links between trade agreements, food environments and diets from an obesity and non-communicable disease (NCD) perspective. Based on the key issues identified through the review, the paper outlines an approach for monitoring the potential impact of trade agreements on food environments and
obesity/NCD risks. The proposed monitoring approach encompasses a set of guiding principles, recommended procedures for data collection and analysis, and quantifiable ‘minimal’, ‘expanded’ and ‘optimal’ measurement indicators to be tailored to national priorities, capacity and resources. Formal risk assessment processes of existing and evolving trade and investment agreements,
which focus on their impacts on food environments will help inform the development of healthy trade policy, strengthen domestic nutrition and health
policy space and ultimately protect population nutrition.The following organizations provided funding support for the travel of participants

Exchange bias between van der Waals materials: tilted magnetic states and field-free spin-orbit-torque switching
Magnetic van der Waals heterostructures provide a unique platform to study
magnetism and spintronics device concepts in the two-dimensional limit. Here,
we report studies of exchange bias from the van der Waals antiferromagnet CrSBr
acting on the van der Waals ferromagnet Fe3GeTe2 (FGT). The orientation of the
exchange bias is along the in-plane easy axis of CrSBr, perpendicular to the
out-of-plane anisotropy of the FGT, inducing a strongly tilted magnetic
configuration in the FGT. Furthermore, the in-plane exchange bias provides
sufficient symmetry breaking to allow deterministic spin-orbit torque switching
of the FGT in CrSBr/FGT/Pt samples at zero applied magnetic field. A minimum
thickness of the CrSBr greater than 10 nm is needed to provide a non-zero
exchange bias at 30 K
Exploring the dynamics of food-related policymaking processes and evidence use in Fiji using systems thinking
Validation of a Dynamic Measure of Current Cognitive Reserve in a Longitudinally Assessed Sample of Healthy Older Adults.
Cognitive reserve (CR) is a theoretical construct describing the underlying cognitive capacity of an individual that confers differential levels of resistance to, and recovery from, brain injuries of various types. To date, estimates of an individual's level of CR have been based on single proxy measures that are retrospective and static in nature. To develop a measure of dynamic change in CR across a lifetime, we previously identified a latent factor, derived from an exploratory factor analysis of a large sample of healthy older adults, as current CR (cCR). In the present study, we examined the longitudinal results of a sample of 272 older adults enrolled in the Tasmanian Healthy Brain Project. Using results from 12-month and 24-month reassessments, we examined the longitudinal validity of the cCR factor using confirmatory factor analyses. The results of these analyses indicate that the cCR factor structure is longitudinally stable. These results, in conjunction with recent results from our group demonstrating dynamic increases in cCR over time in older adults undertaking further education, lend weight to this cCR measure being a valid estimate of dynamic change in CR over time
