Advancing sustainable consumption in the UK and China: the mediating effect of pro-environmental self-identity

In this paper, we respond to the call for more holistic and culturally diverse research to advance understanding of (non)sustainable consumption behaviour. Our conceptual model incorporates materialism, environmental concern, social consumption motivation, pro-environmental self-identity and sustainable consumption behaviours. This paper contributes to knowledge by examining the mediating role of pro-environmental self-identity to more fully explain consumers’ (non)sustainable consumption behaviour. An international online panel survey was employed in the UK (n = 1037) and China (n = 1025). Findings show that pro-environmental self-identity partially or fully mediates the relationships between materialism, environmental concern, social consumption motivation and sustainable consumption behaviours. Important cultural differences also emerged, for example, the positive effect of materialism on Chinese consumer’s sustainable consumption, which is contrary to Western evidence. We suggest bolder, culturally informed and more reflexive marketing strategies are needed to significantly advance sustainable consumption, thus effectively helping to redress the crisis facing our planet

Critiquing a Utopian idea of Sustainable Consumption: A Post-Capitalism Perspective

This paper proposes and critiques the idea of a post-capitalism sustainable consumption utopia to improve the ecological and human wellbeing of the planet. Such a notion can stimulate new imaginative thinking on a future sustainable world not dominated by neoliberalism. It can also strengthen SDG-12: responsible consumption and production. To do so, it examines the influence of pro-environmental self-identity, market-based barriers, and knowledge barriers on sustainable consumption buying, product lifetime extension, and environmental activism. Survey data was collected via online panels in Sweden (n=504) and the USA (n=1,017). Richly varied and complex findings emerge supporting the merit of this utopian idea. In particular, the importance of pro-environmental self-identity. This study illustrates how post-capitalism radical incrementalism and people power can initiate change using the civic, political, and environmental activism in sustainable consumption behaviours. Emerging implications for the viability of SDG-12 are also considered. This work offers rich opportunities for further research

Investigating Sustainable Consumption Behaviours: A US-China Perspective

In this paper we examine the sustainable consumption behaviours of two culturally distinct nations-America and China – utilising an online panel survey of 1,018 adult panel respondents in America and 1025 adult panel respondents in China. We investigate the influence of the multiple constructs of materialism, social consumption motivation, environmental concern and pro-environmental self-identity on American and Chinese consumers' sustainable consumption behaviours and whether pro-environmental self-identity acts as a mediating variable in these relationships. Our findings reveal cultural differences and similarities across our constructs, with pro-environmental self-identity emerging as a mediator, to varying degrees, in both cultures. An important cultural difference in China also materialised, namely the 'positive effect' of materialism on Chinese consumer's sustainable consumption – green materialism-which is counter to Western evidence and raises important questions about the meaning of consuming sustainably. Overall our use of these multiple constructs, combined with Eastern and Western data, enables us to enrich research evidence to increase understanding of (non)sustainable consumption behaviour and how this behaviour can begin to be advanced. It is evident that cultural tailoring of sustainability marketing strategies is necessary, and long-overdue and further cultural research is necessary to inform the effective design and delivery of them

Cultivating sustainable consumption: The role of harmonious cultural values and pro-environmental self-identity

This paper investigates the connections between harmonious cultural values, pro-environmental self-identity and consumers’ sustainable consumption behaviours spanning acquisition, usage and disposal. It evaluates the relevance of Chinese cultural values that purport harmony between humans, nature and society i.e. man-nature orientation and horizontal/vertical dimensions of individualism-collectivism. The results from the online survey with 503 urbanised Chinese reveal these values disparately influence this consumption. Despite the limited direct behavioural effect of these harmonious values, pro-environmental self-identity plays an important role in mediating their indirect effects on the five behaviours. This paper therefore extends theorisation of the values-identity-behaviour relationship from a cultural-values orientation perspective. It offers new insights to understand urbanised Chinese consumers' sustainable consumption behaviours

Appraising the influence of pro-environmental self-identity on sustainable consumption buying and curtailment in emerging markets: Evidence from China and Poland

Understanding sustainable consumption buying and curtailment behavior in emerging markets is limited, yet this knowledge is vital to the future of these economies. The newer conceptualization of pro-environmental self-identity (PESI), as environmentally-friendly dynamic-self, can significantly inform comprehension of these behaviors, and strengthen them. Utilizing intra-personal influences and situational cueing, this paper appraises the influence of PESI on the sustainable buying and curtailment behaviors of consumers in China and Poland. Surveying these consumers, PESI was confirmed as a significant influence on their buying and curtailment behaviors. Contextual and behavioral distinctions also emerged, highlighting a buying emphasis in China and curtailment orientation in Poland. Notably, PESI was found to be multi-activated by situational cueing, moral responsibility, assessment, social desirability, tinted by consumer effectiveness and knowledge. Important implications arise for eco-innovation and buying and curtailment policy-making in emerging markets. PESI consumers have a potential active stakeholder role in this innovation and policy development

Low Adiponectin Levels Are an Independent Predictor of Mixed and Non-Calcified Coronary Atherosclerotic Plaques

Atherosclerosis is the primary cause of coronary artery disease (CAD). There is increasing recognition that lesion composition rather than size determines the acute complications of atherosclerotic disease. Low serum adiponectin levels were reported to be associated with coronary artery disease and future incidence of acute coronary syndrome (ACS). The impact of adiponectin on lesion composition still remains to be determined. We measured serum adiponectin levels in 303 patients with stable typical or atypical chest pain, who underwent dual-source multi-slice CT-angiography to exclude coronary artery stenosis. Atherosclerotic plaques were classified as calcified, mixed or non-calcified. In bivariate analysis adiponectin levels were inversely correlated with total coronary plaque burden (r = -0.21, p = 0.0004), mixed (r = -0.20, p = 0.0007) and non-calcified plaques (r = -0.18, p = 0.003). No correlation was seen with calcified plaques (r = -0.05, p = 0.39). In a fully adjusted multivariate model adiponectin levels remained predictive of total plaque burden (estimate: -0.036, 95%CI: -0.052 to -0.020, p<0.0001), mixed (estimate: -0.087, 95%CI: -0.132 to -0.042, p = 0.0001) and non-calcified plaques (estimate: -0.076, 95%CI: -0.115 to -0.038, p = 0.0001). Adiponectin levels were not associated with calcified plaques (estimate: -0.021, 95% CI: -0.043 to -0.001, p = 0.06). Since the majority of coronary plaques was calcified, adiponectin levels account for only 3% of the variability in total plaque number. In contrast, adiponectin accounts for approximately 20% of the variability in mixed and non-calcified plaque burden. Adiponectin levels predict mixed and non-calcified coronary atherosclerotic plaque burden. Low adiponectin levels may contribute to coronary plaque vulnerability and may thus play a role in the pathophysiology of ACS

Life and living in advanced age: a cohort study in New Zealand - Te Puāwaitanga o Nga Tapuwae Kia Ora Tonu, LiLACS NZ: Study protocol

The number of people of advanced age (85&thinsp;years and older) is increasing and health systems may be challenged by increasing health-related needs. Recent overseas evidence suggests relatively high levels of wellbeing in this group, however little is known about people of advanced age, particularly the indigenous Māori, in Aotearoa, New Zealand. This paper outlines the methods of the study Life and Living in Advanced Age: A Cohort Study in New Zealand. The study aimed to establish predictors of successful advanced ageing and understand the relative importance of health, frailty, cultural, social &amp; economic factors to successful ageing for Māori and non-Māori in New Zealand

Cystatin C and Cardiovascular Disease

Background Epidemiological studies show that high circulating cystatin C is associated with risk of cardiovascular disease (CVD), independent of creatinine-based renal function measurements. It is unclear whether this relationship is causal, arises from residual confounding, and/or is a consequence of reverse causation. Objectives The aim of this study was to use Mendelian randomization to investigate whether cystatin C is causally related to CVD in the general population. Methods We incorporated participant data from 16 prospective cohorts (n = 76,481) with 37,126 measures of cystatin C and added genetic data from 43 studies (n = 252,216) with 63,292 CVD events. We used the common variant rs911119 in CST3 as an instrumental variable to investigate the causal role of cystatin C in CVD, including coronary heart disease, ischemic stroke, and heart failure. Results Cystatin C concentrations were associated with CVD risk after adjusting for age, sex, and traditional risk factors (relative risk: 1.82 per doubling of cystatin C; 95% confidence interval [CI]: 1.56 to 2.13; p = 2.12 × 10−14). The minor allele of rs911119 was associated with decreased serum cystatin C (6.13% per allele; 95% CI: 5.75 to 6.50; p = 5.95 × 10−211), explaining 2.8% of the observed variation in cystatin C. Mendelian randomization analysis did not provide evidence for a causal role of cystatin C, with a causal relative risk for CVD of 1.00 per doubling cystatin C (95% CI: 0.82 to 1.22; p = 0.994), which was statistically different from the observational estimate (p = 1.6 × 10−5). A causal effect of cystatin C was not detected for any individual component of CVD. Conclusions Mendelian randomization analyses did not support a causal role of cystatin C in the etiology of CVD. As such, therapeutics targeted at lowering circulating cystatin C are unlikely to be effective in preventing CVD
