Abstract

Although physical activity and sedentary behavior are moderately heritable, little is known about the mechanisms that influence these traits. Combining data for up to 703,901 individuals from 51 studies in a multi-ancestry meta-analysis of genome-wide association studies yields 99 loci that associate with self-reported moderate-to-vigorous intensity physical activity during leisure time (MVPA), leisure screen time (LST) and/or sedentary behavior at work. Loci associated with LST are enriched for genes whose expression in skeletal muscle is altered by resistance training. A missense variant in ACTN3 makes the alpha-actinin-3 filaments more flexible, resulting in lower maximal force in isolated type IIA muscle fibers, and possibly protection from exercise-induced muscle damage. Finally, Mendelian randomization analyses show that beneficial effects of lower LST and higher MVPA on several risk factors and diseases are mediated or confounded by body mass index (BMI). Our results provide insights into physical activity mechanisms and its role in disease prevention.

16. Exploring How to Optimise Transformative Pro-Environmental Behaviour Changes via Nudging on Shared Values Crystallisation.

Abstract

Transformative learning processes that can trigger deep and long-lasting behaviour changes are highly sought after for targeted improvements ranging from human diet and health to pro-environmental behaviours. A step forward was the reporting of a method that reliably produces transformative learning outcomes (TLOs) as an (incidental) effect of group shared values crystallisation, but the theme of the TLOs could not be targeted, e.g., for pro-environmental behaviours. A recent exploratory study bolted on environmentally themed pre-Nudging and unexpectedly produced a heavy bias towards pro-environmental behaviour changes. Here, we investigated more systematically the influences of different Nudging types upon TLO themes produced using two further case study designs created for comparability with earlier studies and using the same process (WeValue InSitu) and post-event data collection of TLOs categorised as environmental/not and behavioural/not. Our findings show that most Nudging had no effect, including raising the profile of environmental photos and the materials used in the crystallisation process, having participants reflect on their environmental identities, or emphasising environmental topics before going home. However, Nudging which involved answering written questions on specific personal pro-environmental actions such as recycling, applied early on, was linked to desired results. This has pragmatic significance for sustainability practitioners and raises questions for further research on the mechanisms of both active learning and Nudging. [ABSTRACT FROM AUTHOR]

Abstract

Physical activity (PA) may modify the genetic effects that give rise to increased risk of obesity. To identify adiposity loci whose effects are modified by PA, we performed genome-wide interaction meta-analyses of BMI and BMI-adjusted waist circumference and waist-hip ratio from up to 200,452 adults of European (n = 180,423) or other ancestry (n = 20,029). We standardized PA by categorizing it into a dichotomous variable where, on average, 23% of participants were categorized as inactive and 77% as physically active. While we replicate the interaction with PA for the strongest known obesity-risk locus in the FTO gene, of which the effect is attenuated by ~30% in physically active individuals compared to inactive individuals, we do not identify additional loci that are sensitive to PA. In additional genome-wide meta-analyses adjusting for PA and interaction with PA, we identify 11 novel adiposity loci, suggesting that accounting for PA or other environmental factors that contribute to variation in adiposity may facilitate gene discovery.

Abstract

Objective: This work aims to demonstrate an original approach to identify links between locally situated shared values and contextual factors of stunting. Stunting results from multi-factorial and multi-sectoral determinants, but interventions typically neglect locally situated lived experiences, which contributes to problematic designs that are not meaningful for those concerned and/or relatively ineffective. Design: This case study investigates relevant contextual factors in two steps: by first facilitating local stakeholder groups (n 11) to crystallise their shared-values-in-action using a specialised method from sustainability studies (WeValue_InSitu (WVIS)). Secondly , participants (n 44) have focus group discussions (FGD) about everyday practices around child feeding/food systems, education and/or family life. Because the first step strongly grounds participants in local shared values, the FGD can reveal deep links between contextual factors and potential influences on stunting. Setting: Kaffrine, Senegal, an 'Action Against Stunting Hub' site. December 2020. Participants: Eleven stakeholder groups of mothers, fathers, grandmothers, pre-school teachers, community health workers, farmers, market traders and public administrators. Results: Local contextual factors of stunting were identified, including traditional beliefs concerning eating and growing practices; fathers as decision-makers; health worker trust; financial non-autonomy for women; insufficient water for preferred crops; merchants' non-access to quality produce; religious teachings and social structures affecting children's food environment. Conclusions: Local contextual factors were identified. Pre-knowledge of these could significantly improve effectiveness of intervention designs locally, with possible applicability at other sites. The WVIS approach proved efficient and useful for making tangible contextual factors and their potential links to stunting, via a lens of local shared values, showing general promise for intervention research.
