Background
Mobile health (mHealth) behaviour change programmes use mobile phones and the internet to deliver health information and behaviour change support to participants. Such programmes offer a potentially cost-effective way to reach many individuals who do not currently access weight loss services. We developed a mHealth weight management programme using proven face-to-face behaviour change techniques and incorporating target population input. Our aim was to evaluate the feasibility, acceptability and potential effectiveness of this programme for ethnically diverse adults with a view to informing a larger trial.
Results
Fifty three adults who had a BMI of ≥25 kg/m2 and wanted to lose weight (81% female, mean age 42 years, mean BMI 35.7 kg/m2, 26% Maori, 34% Pacific) received the eight-week mHealth weight loss programme. Anthropometric measures were taken at two face-to-face assessments at baseline and 12-weeks (i.e. four weeks after cessation of intervention).
Twelve-week follow-up measurements were available for 36/53 participants (68%). Non-completers were younger and more likely to be male and of Pacific ethnicity. Thirty five participants (66%) reported reading ‘all or most’ text messages sent and 96% responded to at least one text data collection question over the eight-week active intervention period. Eighty one per cent of participants logged in to the study website at least once during the eight-week study period. In the intention-to-treat analysis, mean weight change was -1.0 kg (SD 3.1) at 12 weeks (p = 0.024) and change in BMI was -0.34 kg/m2 (SD 1.1) (p = 0.026). In the completers only analysis (n = 36), mean weight change was -1.4 kg (SD 3.6) (p = 0.023) and change in BMI was -0.50 kg/m2 (SD 1.3) (p = 0.025).
Conclusions
A mHealth weight management programme is feasible to deliver to an ethnically diverse population. Changes in body weight and BMI at 12 weeks indicate that the programme could be effective in supporting people with weight loss. However, the high dropout rate indicates a need for further improvements to the programme.

BACKGROUND/OBJECTIVES: To examine the relationship between diet quality and mental health in an ethnically diverse adolescent population in New Zealand.
SUBJECTS/METHODS: Cross-sectional, population-based study design. Data were available at baseline for 4249 students. Responses from self-reported dietary questionnaires were used to assess diet quality; healthy eating and unhealthy eating were assessed as two separate scales. Mental health was assessed by the emotional subscale of the PedsQL instrument.
RESULTS: Eating a healthy diet was significantly associated with better emotional health (Po0.001) and eating an unhealthy diet was significantly associated with greater emotional distress (Po0.001), after controlling for age, ethnicity and gender. The healthy and unhealthy eating scales were independently related to mental health scores.
CONCLUSIONS: These findings contribute to a growing body of literature that diet quality is associated with mental health in adolescents. Further research is warranted to determine whether improvements to the diets of adolescents can have meaningful improvements to mental well-being.

Food marketing is recognized as an important factor influencing children's food preferences and consumption. The purpose of this study was to examine the nature and extent of unhealthy food marketing and non-branded food references in magazines targeted at and popular among children and adolescents 10–17 years in New Zealand. A content analysis was conducted of all food references (branded and non-branded) found in the five magazines with the highest readership among 10–17 year olds, and the three magazines (of which two were already included among the five most popular magazines) targeted to 10–17 year olds. For each of the six magazines one issue per month (n = 72 issues in total) over a one-year period (December 2012–January 2014) was included. All foods referenced were classified into healthy/unhealthy according to the food-based Ministry of Health classification system. Branded food references (30% of total) were more frequent for unhealthy (43%) compared to healthy (25%) foods. Magazines specifically targeted to children and adolescents contained a significantly higher proportion of unhealthy branded food references (72%, n = 51/71) compared to the most popular magazines among children and adolescents (42%, n = 133/317), of which most were targeted to women. ‘Snack items’ such as chocolates and ice creams were marketed most frequently (n = 104; 36%), while ‘vegetables and fruits’ were marketed the least frequently (n = 9; 3%). Direct advertisements accounted for 27% of branded food references and 25% of those featured health or nutrition claims. Both branded and non-branded food references were common within magazines targeted at and popular among children and adolescents, and skewed toward unhealthy foods. This raises concerns about the effectiveness of self-regulation in marketing and emphasizes that government regulations are needed in order to curb children's current potential high exposures to unhealthy food marketing. In addition, magazine editors could take socially responsible editorial positions in regard to healthy eating.
