Beach safety education for primary school children

Childhood drowning remains a serious public health problem worldwide. The Australian Water Safety Council has set as one of its highest priorities the reduction of drowning deaths in children aged 0–14 years. However, concerns have recently been raised that many students completing primary school still lack the ability to recognize potential aquatic risks, cope with emergencies or assist someone else in danger. In this study, 107 primary school children aged 11–12 completed a one day training programme led by surf lifesaving instructors. Pre, post and eight week follow-up measures showed statistically significant improvements in recognition of the red ‘beach closed’ flag, aquatic safety signs, how to identify a rip current and choosing the safest place to swim at a beach that included a rip current in the picture. Following training students were more willing to provide first aid assistance to family members and friends in an emergency situation. Findings reinforce the value of school-based training that provides a general foundation for aquatic safety, with the caveat that current programmes must be evaluated to ensure their content has a robust prevention focus.     

What Initiatives Are British Food Retailers Taking to Improve Children’s Health and Nutrition?

Along with food manufacturers, retailers contribute directly to the national diet. While efforts to reformulate private-label products have been assessed, little research considers other voluntary initiatives to impact public health. We explore efforts targeting children’s health and nutrition. Making use of the corporate social responsibility reports of the seven leading retailers from 2006 to 2011, we examine the types of actions, by which retail chains and when. Before 2008, most retailers reported on initiatives promoting children’s nutrition education and physical activity in schools. Since 2009, references to such programs have decreased, with a shift toward child wellness. We find that retailers differ in approaches and commitment. Those with larger market shares mention initiatives more frequently. Most activities are related to nutrition education, developing cooking skills, and promotion of physical activity and not product reformulation. Our research suggests these efforts are not coordinated, might be misplaced, and do not persist over time.     

Using partial identification methods to estimate the effect of violence against women on their children’s health outcomes

A growing literature in economics seeks to estimate the costs of violence against women by examining, for example, its impact on the health outcomes of their children. However, it is difficult to assign a causal interpretation to these nonexperimental studies due to the presence of unobservable characteristics affecting violence and health outcomes simultaneously. The lack of credible instrumental variables applicable in several countries further limits our knowledge. I address this gap by using new partial identification methods to estimate the relative size of the unobservables needed to eliminate the estimated effects in nonexperimental studies. I also expand the external validity of the analysis by using data from five standardized nationally representative household surveys in Latin America. Consistent with previous studies, cross-sectional estimates show large negative associations between violence against women and an array of child health outcomes. However, when accounting for omitted variable bias, at best, two-thirds of the estimates remain robust and they are concentrated on the outcomes with the largest cross-sectional estimated impacts.     

In the wake of conflict: the long-term effect on child nutrition in Uganda

The Lord’s Resistance Army (LRA) insurgency from 1986 to 2006 is one of the longest conflicts in Uganda. This paper examines the effect of the LRA insurgency on child nutrition using the 2011 Uganda Demographic and Health Survey. The distance from each village to the border of South Sudan is used as an instrument for identifying the intensity of the conflict. We find that each conflict event in a village lowers weight-for-age z-scores and weight-for-height z-scores for children born after the conflict. We further investigate a possible heterogeneous conflict effect on child nutrition in terms of gender, region, and maternal education. Low household wealth, limited access to healthcare, and poor maternal nutrition appear to be channels through which the conflict inhibits the growth and development of children 5 years after the end of the conflict.     

Effect of Parental Migration on the Academic Performance of Left‐behind Middle School Students in Rural China

China's rapid development and urbanization over the past 30 years have caused large numbers of rural residents to migrate to urban areas in search of work. This has created a generation of children who remain behind in rural areas when their parents migrate for work. Previous research has found mixed impacts of parental migration on the educational achievement of left‐behind children (LBC), perhaps because of methodological deficiencies and lack of recognition of the heterogeneity of this population of children. Our study attempts to examine the impact of six types of parental migration on the academic achievement of a rural junior high school sample. Our study uses a panel of 7148 junior high school students to implement a difference‐in‐difference analysis and finds that parental migration has a negative and significant impact on the academic achievement of junior high school students. Our study suggests that the Chinese Government should implement measures to dismantle barriers to the human capital accumulation of LBC to ensure sustainable economic growth and human capital development in China.
