Do enhancements to the urban built environment improve physical activity levels among socially disadvantaged populations?

There is growing recognition that the urban built environment influences physical activity at the population level, although the effects on disadvantaged groups are less well understood. Using the examples of open / green space and street connectivity, this paper explores whether enhancements to the built environment have potential for addressing physical activity-related health inequalities among Maori, Pacific and low income communities in New Zealand.

Economic incentives to promote healthier food purchases: exploring acceptability and key factors for success

Despite increasing interest, little is known about the beliefs and views of the public in relation to the use of economic incentives as a means to promote healthy eating. This study explores views of ethnically and socioeconomically diverse shoppers regarding acceptability of economic incentives to promote healthier food purchases, and factors likely to affect the success of such schemes.

Cytisine's Potential to Be Used as a Traditional Healing Method to Help Indigenous People Stop Smoking: A Qualitative Study With Maori

Māori experience a disproportionate amount of smoking-related harm (46% of adult Māori smoke). Effective cessation treatments that are both accessible and attractive to Māori are urgently needed. Cytisine (a plant extract found in Golden Rain [Cytisus laburnum L.] and the New Zealand Kowhai [Sophora tetraptera L.] has a similar molecular makeup to nicotine, has been used successfully as a cessation product in central and eastern Europe and central Asia for many years, and is low priced. Recent reviews have found that cytisine is twice as effective as a placebo for smoking cessation. This study aimed to explore cytisine's potential as a ‘rongoā Māori’ (traditional Māori remedy) and its attractiveness to Māori smokers compared with other cessation products.

Study protocol for a randomised trial of nicotine-free cigarettes as an adjunct to usual NRT-based cessation practice, in people who wish to stop smokin

Current smoking cessation treatments focus on addressing the pharmacological dependence of smokers on nicotine. However, new strategies are needed that address both nicotine dependence and the psychological dependence on cigarettes as the source of nicotine. Evidence from a number of small smoking cessation studies suggests that the use of cigarettes with reduced nicotine content, in combination with nicotine replacement therapy (NRT), may help reduce withdrawal symptoms and increase quit rates. This paper describes the protocol for a large randomised-controlled trial to test the effect of using nicotine-free cigarettes together with NRT on long-term quit rates.

A Theory-Based Video Messaging Mobile Phone Intervention for Smoking Cessation: Randomized Controlled Trial

Advances in technology allowed the development of a novel smoking cessation program delivered by video messages sent to mobile phones. This social cognitive theory-based intervention (called “STUB IT”) used observational learning via short video diary messages from role models going through the quitting process to teach behavioral change techniques.
