The Metabolic Syndrome and All-Cause Mortality in an Insured Lives Population

Abstract

Metabolic syndrome and its association with mortality have not been studied in insured lives populations. The Swiss Re Study evaluated metabolic syndrome prevalence and associated mortality from all causes and circulatory disease in a cohort of 35,470 predominantly healthy individuals, aged 18–83 years, who were issued life insurance policies between 1986 and 1997. Metabolic syndrome was defined using the National Cholesterol Education Program (NCEP) Expert Panel Adult Treatment Panel (ATP) III guidelines. The NCEP obesity criteria were modified with a prediction equation using body mass index, gender, and age substituted for waist circumference. Adjustments also were made for nonfasting triglyceride and blood glucose values. Risk ratios for policyholders identified with metabolic syndrome were 1.16 (P = .156) for mortality from all causes and 1.45 (P = .080) for mortality from circulatory disease compared with individuals without the syndrome. Risk was proportional to the number of components, or score, of the metabolic syndrome present. Risk ratios for metabolic syndrome score were 1.14 (P < .001) for mortality from all causes and 1.38 (P < .001) for mortality from circulatory disease compared with individuals without metabolic syndrome factors. In both all-cause and circulatory death models, relative risk was highest for the blood pressure risk factor. Based on a modified NCEP definition, increased mortality risk is associated with metabolic syndrome in an insured lives cohort and has life insurance mortality pricing implications.     

A consistent characteristic function-based test for conditional independence

Y is conditionally independent of Z given X   if Pr{f(y|X,Z)=f(y|X)}=1$\{f(y|X,Z)=f(y|X)\}=1$ for all y on its support, where f(·|·)$f(·|·)$ denotes the conditional density of Y   given (X,Z)$(X,Z)$ or X.$X.$ This paper proposes a nonparametric test of conditional independence based on the notion that two conditional distributions are equal if and only if the corresponding conditional characteristic functions are equal. We extend the test of Su and White (2005. A Hellinger-metric nonparametric test for conditional independence. Discussion Paper, Department of Economics, UCSD) in two directions: (1) our test is less sensitive to the choice of bandwidth sequences; (2) our test has power against deviations on the full support of the density of (X,Y,Z$X,Y,Z$). We establish asymptotic normality for our test statistic under weak data dependence conditions. Simulation results suggest that the test is well behaved in finite samples. Applications to stock market data indicate that our test can reveal some interesting nonlinear dependence that a traditional linear Granger causality test fails to detect.     

Museum pricing: challenges to theory development and practice

• The museum sector has undergone considerable change in the last few decades, which has been a result of both internal and external forces. The topic of pricing in museums, however, has attracted little interest from researchers in the field despite the sector's need to understand it better. This study aimed to address this gap in knowledge. Results of a comprehensive literature review on pricing highlight that the topic of pricing in museums is problematic, as a range of issues, social, political and often value-laden, must be considered before pricing decisions can be made. The study highlights that there is diversity in the sector with regard to pricing, but that museums generally adopt a unilateral approach to pricing. Researchers in entrepreneurial marketing have noted that conventional pricing theory is being turned on its head and they argue that deciding what prices to charge represents one of the more entrepreneurial strategies for organisations. This study indicates that, within the context of museums, marketers are failing to recognise and capitalise on such pricing opportunities. Approaches to setting multiple museum pricing strategies, depending on the market context, are proposed in this paper. In this way, knowledge of museum pricing can optimise the organisational outcomes of museums while continuing to meet their social responsibilities.

The Crash of 1882 and the Bailout of the Paris Bourse

The crash of the French stock market in 1882 presented the Paris Bourse with its worst crisis of the nineteenth century. Its structure was similar in key respects to today’s futures markets, with a dominant forward market leading the Bourse to adopt a common fund to guarantee transactions and liquidity. While this mutualization of risk protects clients and brokers from idiosyncratic shocks, it is generally assumed that it also provides considerable protection against systemic shocks, as no twentieth century exchange has been forced to shut down. Using new archival data, this paper shows how a stock market crash overwhelmed the Bourse’s common fund. Only an emergency loan from the Bank of France, intermediated by the largest banks, prevented a closure of the Bourse.

Economic and environmental impacts of trade liberalization: The case of Indonesia

In recent years, there has been a growing interest in the environmental impacts of trade liberalization. This paper provides further discourse in this area with a study on Indonesia and its trade agreements with Japan (IJEPA) and ASEAN (AFTA). A static global CGE model, known as the Global Trade Analysis Project, was used to project the Indonesian economy to the year 2022, with and without tariff reforms agreed under the agreements. Environmental impacts are assessed using different pollution indicators—air, water and waste. The study suggests that Indonesia would grow rapidly over the period considered with a large deterioration in its environment. Following these, however, the agreements only have a marginal positive impact on Indonesia's output but with a noticeable increase in trade flows and signs of trade diversion. Overall AFTA has a greater impact on the Indonesian economy compared to IJEPA. Similarly, the impact of trade liberalization on the environment is marginal. On the whole, tariff reform is inducing air pollution and reducing water pollution. In conclusion, the study suggests that Indonesia's participation in the AFTA and IJEPA agreements is not likely to bring drastic changes to her economic and environmental performance.     

The safety attitudes of people who use multi-purpose recreation facilities as a physical activity setting

Multi-purpose recreation facilities (MPRFs) are a popular setting for physical activity and it is therefore important that they are safe for all patrons. However, the attitudes of MPRF users towards safety are a potential barrier to the success of injury prevention programmes implemented within MPRFs. This article reports a survey of the safety attitudes of over 700 users of four indoor MPRFs. Factor analysis of 12 five-point Likert scale statements showed that the attitudes clustered around three major dimensions - the importance of safety, the benefits of safety and the perceptions of injury risk. Together, these three dimensions accounted for 49% of the variability in the attitudes. More than 85% of respondents agreed/strongly agreed that: safety was an important aspect of physical activity participation; being injured affected enjoyment of physical activity; people should adopt appropriate safety measures for all physical activity; and individuals were responsible for their own safety. The MPRF users, particularly women and older people, were generally safety conscious, believed in adopting safety measures, and were willing to take responsibility for their own safety. Facility managers can be confident that if they provide evidence-based injury prevention interventions in these settings, then users will respond appropriately and adopt the promoted behaviours.
