Injections are one of the most frequently used medical procedures. The World Health Organization (WHO) estimates that 12 billion injections are given annually, 5% of which are administered for immunization and 95% for curative purposes. Unsafe injection practices (especially needle and syringe re-use) are commonplace in low-income country health settings, and place both staff and patients at risk of infection with blood-borne viruses (BBVs). ⋯ An appropriate response on the part of international organizations, governments, health administrators, community organizations and health workers, including those who work in the area of HIV/AIDS prevention, has been slow to emerge. This paper reviews the literature relating to unsafe injection practices and the transmission of BBVs in low-income countries in order to raise awareness of the issue and the consequent need to promote injection safety messages amongst both consumers and providers of health care services in these countries. The nature and extent of unsafe injection practices, the burden of blood-borne viral illness attributable to unsafe injection practices, and the factors contributing to these practices are summarized, and possible strategies for promoting injection safety discussed.

Childhood obesity is an increasing health problem in New Zealand and many other countries. Information is needed to guide interventions that reduce the 'obesogenic' (obesity-promoting) elements of school environments. The aim of this study was to identify and measure the obesogenic elements of the school environment and the canteen sales of energy-dense foods and drinks. ⋯ Only 50% felt there was management support for healthy food choices and only 39% agreed that mainly nutritious food was offered by the food service. 'Less healthy' choices dominated food sales by more than 2:1, with pies being the top selling item (>55000 per week). We found that the food environment was not conducive to healthy food choices for the children at New Zealand schools and that this was reflected in the high sales of relatively unhealthy foods from the school food services. Programmes that improve school food through policies, availability, prices and school ethos are urgently needed.
