Introduction: Coronary heart disease is a major contributor to the global burden of disease. Appropriate nutrition is a cornerstone of the prevention and treatment of coronary heart disease; however, barriers including cost and access to recommended foods limits long-term adherence for many. We are conducting, in adults with coronary heart disease, a randomised controlled trial comparing usual care with two dietary interventions in which usual care is augmented by 12 weeks free delivered groceries.

A spatial modelling approach was used to explore how a proximity limit (150 m, 300 m, and 450 m) between tobacco retailers may impact different neighbourhoods in New Zealand. Neighbourhoods were categorised into three density groups (0, 1-2, 3+ retailers). As the proximity limit increases, there is a progressive redistribution of neighbourhoods in the three density groups with, the 3+ density group incorporating fewer neighbourhoods and the 0 and 1-2 density groups conversely each consisting of more.

Introduction: Lower limb ischaemia secondary to occlusion of a lower limb artery is a limb-threatening condition that can be effectively treated by catheter-directed thrombolysis (CDT). The purpose of this study was to examine treatment outcomes of CDT both at the time of treatment and ongoing patency up to 12 months following treatment. The secondary aim of the study was to investigate the influence of age of occlusion and treatment duration on success and complication rates.

Introduction: One policy option to reduce the density of tobacco retailers is to restrict the distance retailers can be located to each other. This study examined the impacts of proximity limits of 150 m, 300 m and 450 m between tobacco retailers in New Zealand and if critical threshold reduction in tobacco retailers of 90%-95% would be achieved.

Methods: Using a spatial modelling approach, tobacco retailers were randomly removed based on a minimum distance between retailers until there were zero retailers within each scenario's minimum distance.

This study examined whether positive development (PD) in adolescence and young adulthood predicts offspring behavior in two Australasian intergenerational cohorts. The Australian Temperament Project Generation 3 Study assessed PD at age 19-28 (years 2002-2010) and behavior in 1165 infants (12-18 months; 608 girls) of 694 Australian-born parents (age 29-35; 2012-2019; 399 mothers). The Dunedin Multidisciplinary Health and Development Parenting Study assessed PD at age 15-18 (years 1987-1991) and behavior in 695 preschoolers (3-5 years; 349 girls) and their New Zealand born parents (age 21-46; 1994-2018; 363 mothers; 89% European ethnicity).

Excessive exposure to ultraviolet radiation during adolescence can have a lasting effect on long-term skin cancer risk. Skin cancer prevention interventions for adolescents have been less commonly investigated than those for children and adults. The study objectives were to develop and evaluate the feasibility of a secondary school-based appearance focused intervention, including the development and testing of protocols and instruments, as a resource module that could be efficiently integrated into the secondary school science curriculum.

Background: In New Zealand, 34% of deaths occur in the hospital setting where junior doctors are at the frontline of patient care. The death rate in New Zealand is expected to double by 2068 due to the aging population, but many studies report that graduates feel unprepared to care for people near the end of life and find this to be one of the most stressful parts of their work. International guidelines recommend that palliative and end of life care should be a mandatory component of undergraduate medical education, yet teaching varies widely and remains optional in many countries.

Background: Nurses play a vital role in the care of people with advanced life-limiting illnesses, so palliative and end of life care is an essential skill nurses need to learn. Despite numerous reports in the international literature about educational developments in this area, there are widespread inconsistencies in undergraduate education, and graduates continue to report feeling unprepared for this part of their work. Little is known about how New Zealand nursing students learn about this important area of clinical practice.

Background: Previous studies report a majority of the general public support euthanasia/assisted dying (EAD), while a majority of doctors are opposed. In considering policy decisions about EAD, some may discount the views of doctors because they take them to be based on personal values or tradition, rather than reasons that the general public might share. One way to explore this notion is to examine whether medical students' views change during their medical education.

Background: Beliefs about cancer risk and experience of early detection and treatment can impact on willingness to engage with these initiatives. This study describes changes in perceptions of cancer mortality, early detection and treatment among adult New Zealanders (NZ) between two cross-sectional studies conducted in 2001 and 2014/5. Methods: Data was collected via telephone interviews conducted by trained interviewers in 2001 (231 females and 207 males, 64% response rate) and 2014/5 (588 females and 476 males, 64% response rate).

Objective: Cancer risk reduction messages are a part of cancer control efforts around the world. The complex reality is that risk factors differ for different types of cancer, making clear communication of desired behavioural changes more difficult. This study aims to describe awareness of risk factors for breast, bowel, cervical, prostate and lung cancer and cutaneous melanoma among New Zealanders in 2014/15 and identify changes in awareness since 2001.

Objective: Eating less frequently is associated with increased obesity risk in older children but data are potentially confounded by reverse causation, where bigger children eat less often in an effort to control their weight. Longitudinal data, particularly in younger children, are scarce. We aimed to determine whether eating frequency (meals and snacks) at 2 years of age is associated with past, current or subsequent BMI.
