What is a case-control study?

The authors conducted a meta-analysis of 150 studies in which the risk-taking tendencies of male and female participants were compared. Studies were coded with respect to type of task (e.g., self-reported behaviors vs. observed behaviors), task content (e.g., smoking vs. sex), and 5 age levels. Results showed that the average effects for 14 out of 16 types of risk taking were significantly larger than 0 (indicating greater risk taking in male participants) and that nearly half of the effects were greater than .20. However, certain topics (e.g., intellectual risk taking and physical skills) produced larger gender differences than others (e.g., smoking). In addition, the authors found that (a) there were significant shifts in the size of the gender gap between successive age levels, and (b) the gender gap seems to be growing smaller over time. The discussion focuses on the meaning of the results for theories of risk taking and the need for additional studies to clarify age trends.

Our future: a Lancet commission on adolescent health and wellbeing

Health promotion programs often lack a clearly specified theoretical foundation or are based on narrowly conceived conceptual models. For example, lifestyle modification programs typically emphasize individually focused behavior change strategies, while neglecting the environmental underpinnings of health and illness. This article compares three distinct, yet complementary, theoretical perspectives on health promotion: behavioral change, environmental enhancement, and social ecological models. Key strengths and limitations of each perspective are examined, and core principles of social ecological theory are used to derive practical guidelines for designing and evaluating community health promotion programs. Directions for future health promotion research are discussed, including studies examining the role of intermediaries (e.g., corporate decision-makers, legislators) in promoting the well-being of others, and those evaluating the duration and scope of intervention outcomes.

Translating social ecological theory into guidelines for community health promotion.

This paper is a synopsis of a major report by the WHO which collates information on crashes worldwide. It summarises the key findings and the recommendations of the report. The central theme of the Report is the burden of road traffic injuries and the urgent need for governments and other key players to increase and sustain action to prevent road traffic injuries. The specific objectives are: to describe the burden, intensity, pattern and impacts of road traffic injuries at global, regional and national levels; to examine the key determinants and risk factors; to discuss interventions and strategies that can be employed to address the problem; and to make recommendations for action at local, national and international levels. Key findings include: road traffic injuries are a huge public health and development problem predicted to worsen if appropriate action is not taken; the majority of road traffic injuries occur in low- and middle-income countries; road safety should be addressed using a "systems approach;" road safety is a shared responsibility and public health has a key role to play; and road traffic injuries can be prevented. The Report concludes by offering six recommendations: identify a lead agency in government to guide the national road traffic safety effort; assess the problem, policies and institutional settings; prepare a national road safety strategy and plan of action; allocate financial and human resources to address the problem; implement specific actions to prevent road traffic crashes, minimize injuries and their consequences, and evaluate the impact of these actions; and support the development of national capacity and international co-operation.

High school driver education: further evaluation of the DeKalb County study.

A study was conducted in which young males, under the legal alcohol purchase age of 21, attempted to purchase beer at grocery stores and other retail outlets. Underage purchases were attempted at a sample of stores in Washington, D.C.; Westchester County, New York: and Albany and Schenectady counties, New York. Beer was sold to the underage purchasers at 97 percent of the Washington, D.C. stores, 80 percent of the Westchester County stores, and 44 percent of the Albany and Schenectady stores, despite the fact that such sales are illegal. Beer was more likely to be sold to the underage purchasers at smaller neighborhood stores in urban areas. Sales were least likely in Albany, which experienced recent police enforcement of the alcohol purchase age laws. Vigorous enforcement of the minimum purchase age laws is needed to reverse the current national trend toward more alcohol-related highway fatalities among youth.

The research literature on night driving curfews is reviewed. Driving at night involves high risk, particularly for young beginners. Although only about 15 percent of the total miles of 16-17-year-old drivers occur between 9 p.m. and 6 a.m., about 40 percent of their fatal crashes take place during these hours. Curfews that limit recreational driving at night without an adult have been found to substantially reduce nighttime crashes. Parents of teenagers strongly endorse curfews and favor earlier starting times than prevail in most jurisdictions with curfews. A night driving curfew is an essential component of graduated licensing, a system that phases in young beginners to full-privilege licensure, limiting initial driving to lower-risk situations.
