Systematic Conservation Planning in the Face of Climate Change: Bet-Hedging on the Columbia Plateau

Systematic conservation planning efforts typically focus on protecting current patterns of biodiversity. Climate change is poised to shift species distributions, reshuffle communities, and alter ecosystem functioning. In such a dynamic environment, lands selected to protect today's biodiversity may fail to do so in the future. One proposed approach to designing reserve networks that are robust to climate change involves protecting the diversity of abiotic conditions that in part determine species distributions and ecological processes. A set of abiotically diverse areas will likely support a diversity of ecological systems both today and into the future, although those two sets of systems might be dramatically different. Here, we demonstrate a conservation planning approach based on representing unique combinations of abiotic factors. We prioritize sites that represent the diversity of soils, topographies, and current climates of the Columbia Plateau. We then compare these sites to sites prioritized to protect current biodiversity. This comparison highlights places that are important for protecting both today's biodiversity and the diversity of abiotic factors that will likely determine biodiversity patterns in the future. It also highlights places where a reserve network designed solely to protect today's biodiversity would fail to capture the diversity of abiotic conditions and where such a network could be augmented to be more robust to climate-change impacts

High prevalence of vitamin D insufficiency and its association with BMI-for-age among primary school children in Kuala Lumpur, Malaysia

<p>Abstract</p> <p>Background</p> <p>Deficiencies of micronutrients can affect the growth and development of children. There is increasing evidence of vitamin D deficiency world-wide resulting in nutritional rickets in children and osteoporosis in adulthood. Data on the micronutrient status of children in Malaysia is limited. The aim of this study was to determine the anthropometric and micronutrient status of primary school children in the capital city of Kuala Lumpur.</p> <p>Methods</p> <p>A cross sectional study of primary aged school children was undertaken in 2008. A total of 402 boys and girls aged 7-12 years, attending primary schools in Kuala Lumpur participated in the study. Fasting blood samples were taken to assess vitamin D [as 25(OH)D], vitamin B₁₂, folate, zinc, iron, and ferritin and haemoglobin concentrations. Height-for-age and body mass index for age (BMI-for-age) of the children were computed.</p> <p>Results</p> <p>Most of the children had normal height-for-age (96.5%) while slightly over half (58.0%) had normal BMI-for-age. A total of 17.9% were overweight and 16.4% obese. Prevalence of obesity was significantly higher among the boys (25%) than in the girls (9.5%) (χ²= 22.949; <it>P </it>< .001). Most children had adequate concentrations of haemoglobin, serum ferritin, zinc, folate and vitamin B₁₂. In contrast, 35.3% of the children had serum 25(OH)D concentrations indicative of vitamin D deficiency(≤37.5 nmol/L) and a further 37.1% had insufficiency concentrations (> 37.5-≤50 nmol/L). Among the boys, a significant inverse association was found between serum vitamin D status and BMI-for-age (χ²= 5.958; <it>P </it>= .016).</p> <p>Conclusions</p> <p>This study highlights the presence of a high prevalence of sub-optimal vitamin D status among urban primary school children in a tropical country. In light of the growing problem of obesity in Malaysian children, these findings emphasize the important need for appropriate interventions to address both problems of obesity and poor vitamin D status in children.</p

Vitamin D insufficiency and its association with obesity among primary school children in Kuala Lumpur, Malaysia

Aims: To present findings on low blood vitamin D status and its association with obesity among primary school children in Kuala Lumpur. Methods: A cross-sectional study of primary aged school children was undertaken in 2008. Six primary schools were randomly selected from a zone in Kuala Lumpur with a multi-ethnic population from middle income levels. Fasting blood samples were taken to assess micronutrients including vitamin D [as 25(OH)D]. A total of 402 boys and girls aged 7–12 years participated in the study. Informed consent was obtained from both parents and the subjects

Proceedings of a roundtable event 'Workplace Diet and Health - priorities for researchers and practitioners'

Understanding how the work environment impacts health behaviours is essential to a life course approach in public health nutrition. A roundtable event 'Workplace Diet and Health - priorities for researchers and practitioners' was held by the Nutrition Society in October 2022. The overarching aims of the roundtable event were to consider (i) the relevance of nutritional wellbeing for employers and organisations, (ii) the research priorities for workplace diet and health and (iii) how researchers and practitioners can work with stakeholders in the development and testing of workplace diet and health interventions and nutritional education. Participants represented a range of stakeholders including dietetic and nutrition professionals working in workplace health, academics and science communication with an interest in workplace diet and health, non-governmental organisations and providers of workplace nutritional health and wellbeing programmes. All roundtable participants agreed that good nutrition and access to healthy food at work was part of corporate responsibility comparable to that of health and safety provision. It was recognised that nutritional wellbeing was not seen as a priority by many companies due to the complexity and wide range of employee health and wellbeing options available and the perceived lack of clear financial benefit. Three priority areas were identified and agreed upon by roundtable participants: (1) strengthening the evidence base to demonstrate the tangible benefit of nutritional wellbeing interventions in the workplace, (2) creating a knowledge exchange hub to share best practices and experiences of working across sectors and (3) expand stakeholder engagement in workplace nutritional wellbeing
