Denmark’s Policy on Artificial Trans Fat and Cardiovascular Disease

INTRODUCTION The consumption of trans fat is associated with cardiovascular disease (CVD). In January 2004, Denmark became the first country in the world to regulate the content of artificial trans fat in certain ingredients in food products, which nearly eliminated artificial trans fat from the Danish food supply. The goal of this study was to assess whether Denmarks trans fat policy reduced deaths caused by CVD. METHODS Annual mortality rates in Organisation for Economic Co-operation and Development (OECD) countries from 1990 to 2012 were used to estimate the effect of Denmarks food policy on CVD mortality rates. Synthetic control methods were employed to simulate the CVD mortality trajectory that Denmark would have witnessed in the absence of the policy and to measure the policys impact on CVD mortality rates. Analyses were conducted in 2015. RESULTS Before the trans fat policy was implemented, CVD mortality rates in Denmark closely tracked those of a weighted average of other OECD countries (i.e., the synthetic control group). In the years before the policy, the annual mean was 441.5 deaths per 100,000 people in Denmark and 442.7 in the synthetic control group. In the 3 years after the policy was implemented, mortality attributable to CVD decreased on average by about 14.2 deaths per 100,000 people per year in Denmark relative to the synthetic control group. CONCLUSIONS Denmarks food policy, which restricted the content of artificial trans fat in certain ingredients in its food supply, has been followed by a decrease in CVD mortality rates.

Trans fat and cardiovascular disease mortality: Evidence from bans in restaurants in New York

This paper analyzes the impact of trans fat bans on cardiovascular disease (CVD) mortality rates. Several New York State jurisdictions have restricted the use of ingredients containing artificial trans fat in food service establishments. The resulting within-county variation over time and the differential timing of the policys rollout is used in estimation. The results indicate that the policy caused a 4.5% reduction in CVD mortality rates, or 13 fewer CVD deaths per 100,000 persons per year. The averted deaths can be valued at about

On the Generality of Age Differences in Social and Nonsocial Decision Making

Abstract The Extractive Industries Transparency Initiative (EITI) has received much attention as a scheme that can help reduce corruption in mineral-rich developing economies. To our knowledge, this paper provides the first empirical attempt (using panel data) to explore how EITI membership links to changes in corruption levels. We also examine whether the different stages in EITI implementation (initial commitment, candidature, full compliance) influence the pace of changes in corruption. We find that EITI membership offers, on the whole, a shielding mechanism against the general tendency of mineral-rich countries to experience increases in corruption over time.

Child health, its dynamic interaction with nutrition and health memory--evidence from Senegal.

OBJECTIVES Empirical work with western populations suggests that aging is associated with changes in economic decision making, including, for example, increased prosocial tendencies. We investigated the generality of age effects in social and nonsocial domains by assessing various measures of economic decision making in a rural population from Morocco. METHOD We measured age/cohort differences using a number of economic games (risk game, time preferences game, dictator game, trust game, and public goods game) in over 700 participants ranging from 17 to 92 years of age. RESULTS The results suggest a negative relation between age and risk taking and a concave relation between age and contribution to a public good, but no significant age trends in time preferences, altruism, trust, or trustworthiness. DISCUSSION Our results indicate that the relationship between aging and decision making is not universal and is shaped by local culture and the type of task rather than biological factors alone. More research is needed to understand the unique age trends prevalent in specific populations and tasks.

Polygyny and Child Growth: Evidence From Twenty-Six African Countries

Child malnutrition is pervasive in developing countries and anthropometric measures such as weight-for-height and height-for-age have proven reliable indicators of short term malnutrition and stunting. Rather than studying these indicators separately, we look at their interaction and carve out child health dynamics. Considering height-for-age a childs health stock and weight-for-lagged height a proxy for nutritional inputs, we develop a child health production function that features self-productivity of past health stocks and contemporaneous nutritional inputs. We test the model on a Senegalese panel of 271 children between 0 and 5 years employing dynamic panel methods to control for endogeneity in the production function. In line with previous evidence, we find that children can partially catch-up from malnutrition spells. Yet, child health stocks also deplete quickly and need constant updating in the form of nutrition. This demonstrates the importance of health memory and that malnutrition cannot be fought with snapshot interventions. Consequently, sustainable nutrition interventions have to be long term and yield higher returns the earlier they reach children.

Age-Specific Correlates of Child Growth

ABSTRACT Using household data from twenty-six African countries, this study examines the correlation between four measures of polygyny and child growth. External validity is added to existing small-sample evidence by investigating this correlation across many countries and by controlling for, as well as exploring, sources of heterogeneity at the regional, country, household, and maternal level. Household fixed-effects models indicate that the children of monogamous mothers have significantly greater height-for-age z-scores than children of polygynous mothers. Also, a low ranking in the hierarchy of mothers and the ratio of married women to men are negatively correlated with child height. The correlation varies widely across countries and is strongest for multigenerational polygynous households.

Risk aversion, time preference and health production: Theory and empirical evidence from Cambodia

Growth faltering describes a widespread phenomenon that height- and weight-for-age of children in developing countries collapse rapidly in the first two years of life. We study age-specific correlates of child nutrition using Demographic and Health Surveys from 56 developing countries to shed light on the potential drivers of growth faltering. Applying nonparametric techniques and exploiting within-mother variation, we find that maternal and household factors predict best the observed shifts and bends in child nutrition age curves. The documented interaction between age and maternal characteristics further underlines the need not only to provide nutritional support during the first years of life but also to improve maternal conditions.

The Impact of Land Mines on Child Health: Evidence from Angola

This paper quantifies the relationship between risk aversion and discount rates on the one hand and height and weight on the other. It studies this link in the context of poor households in Cambodia. Evidence is based on an original dataset that contains both experimental measures of risk taking and impatience along with anthropometric measurements of children and adults. The aim of the paper is to (i) explore the importance of risk and time preferences in explaining undernutrition and (ii) compare the evidence stemming from poor households to strikingly similar findings from industrialized countries. It uses an inter-generational approach to explain observed correlations in adults and children that is inspired by the height premium on labor markets. Parents can invest in the health capital of their child to increase future earnings and their consumption when old: better nutrition during infancy translates into better human capital and better wages, and ultimately better financial means to take care of elderly parents. However this investment is subject to considerable uncertainty, since parents neither perfectly foresee economic conditions when the child starts earning nor fully observe the ability to transform nutritional investments into long-term health capital. As a result, risk taking households have taller and heavier children. Conversely, impatience does not affect child health. In the case of adults, only weight and the body mass index (BMI), but not height, are positively and moderately correlated with risk taking and impatience.

Universal health coverage at the macro level: Synthetic control evidence from Thailand

This article estimates the causal impact of land mines on child health in Angola, controlling for conflict exposure. Our identification strategy is based on the geography of the Angolan civil war. We posit that distance between communes and rebel headquarters is an exogenous driver of land mine contamination. We find that land mine intensity is positively correlated with the distance to a set of rebel headquarters. Instrumental variables estimates, based on two household surveys and the Landmines Impact Survey, indicate that land mines have large and negative effects on weight-for-age and height-for-age. We discuss our results with respect to the costs and benefits of land mine clearance, as well as the long-term costs of early malnutrition. We also compare the magnitude of our estimates with those of related studies on the impact of conflict on child health.
