Assessing youth empowerment and co-design to advance Pasifika health: a qualitative research study in New Zealand.

OBJECTIVES: The Pasifika Prediabetes Youth Empowerment Programme (PPYEP) was a community-based research project that aimed to investigate empowerment and co-design modules to build the capacity of Pasifika youth to develop community interventions for preventing prediabetes. METHODS: This paper reports findings from a formative evaluation process of the programme using thematic analysis. It emphasises the adoption, perceptions and application of empowerment and co-design based on the youth and community providers' experiences. RESULTS: We found that the programme fostered a safe space, increased youth's knowledge about health and healthy lifestyles, developed their leadership and social change capacities, and provided a tool to develop and refine culturally centred prediabetes-prevention programmes. These themes emerged non-linearly and synergistically throughout the programme. CONCLUSIONS: Our research emphasises that empowerment and co-design are complementary in building youth capacity in community-based partnerships in health promotion. Implications for public health: Empowerment and co-design are effective tools to develop and implement culturally tailored health promotion programmes for Pasifika peoples. Future research is needed to explore the programme within different Pasifika contexts, health issues and Indigenous groups.

Predictors Linking Obesity and the Gut Microbiome (the PROMISE Study): Protocol and Recruitment Strategy for a Cross-Sectional Study on Pathways That Affect the Gut Microbiome and Its Impact on Obesity.

BACKGROUND: The prevalence of obesity has increased substantially over recent decades and is associated with considerable health inequalities. Although the causes of obesity are complex, key drivers include overconsumption of highly palatable, energy-dense, and nutrient-poor foods, which have a profound impact on the composition and function of the gut microbiome. Alterations to the microbiome may play a critical role in obesity by affecting energy extraction from food and subsequent energy metabolism and fat storage. OBJECTIVE: We report the study protocol and recruitment strategy of the PRedictors linking Obesity and the gut MIcrobiomE (PROMISE) study, which characterizes the gut microbiome in 2 populations with different metabolic disease risk (Pacific and European women) and different body fat profiles (normal and obese). It investigates (1) the role of gut microbiome composition and functionality in obesity and (2) the interactions between dietary intake; eating behavior; sweet, fat, and bitter taste perception; and sleep and physical activity; and their impact on the gut microbiome, metabolic and endocrine regulation, and body fat profiles. METHODS: Healthy Pacific and New Zealand (NZ) European women aged between 18 and 45 years from the Auckland region were recruited for this cross-sectional study. Participants were recruited such that half in each group had either a normal weight (body mass index [BMI] 18.5-24.9 kg/m2) or were obese (BMI ≥30.0 kg/m2). In addition to anthropometric measurements and assessment of the body fat content using dual-energy x-ray absorptiometry, participants completed sweet, fat, and bitter taste perception tests; food records; and sleep diaries; and they wore accelerometers to assess physical activity and sleep. Fasting blood samples were analyzed for metabolic and endocrine biomarkers and DNA extracted from fecal samples was analyzed by shotgun sequencing. Participants completed questionnaires on dietary intake, eating behavior, sleep, and physical activity. Data were analyzed using descriptive and multivariate regression methods to assess the associations between dietary intake, taste perception, sleep, physical activity, gut microbiome complexity and functionality, and host metabolic and body fat profiles. RESULTS: Of the initial 351 women enrolled, 142 Pacific women and 162 NZ European women completed the study protocol. A partnership with a Pacific primary health and social services provider facilitated the recruitment of Pacific women, involving direct contact methods and networking within the Pacific communities. NZ European women were primarily recruited through Web-based methods and special interest Facebook pages. CONCLUSIONS: This cross-sectional study will provide a wealth of data enabling the identification of distinct roles for diet, taste perception, sleep, and physical activity in women with different body fat profiles in modifying the gut microbiome and its impact on obesity and metabolic health. It will advance our understanding of the etiology of obesity and guide future intervention studies involving specific dietary approaches and microbiota-based therapies.

Investigating differences in dietary patterns among a small cross-sectional study of young and old Pacific peoples in NZ using exploratory factor analysis: a feasibility study.

OBJECTIVES: Obesity among Pasifika people living in New Zealand is a serious health problem with prevalence rates more than twice those of the general population (67% vs 33%, respectively). Due to the high risk of developing obesity for this population, we investigated diet quality of Pacific youth and their parents and grandparents. Therefore, we examined the dietary diversity of 30 youth and their parents and grandparents (n=34) to identify whether there are generational differences in dietary patterns and investigate the relationship between acculturation and dietary patterns. METHODS: The study design of the overarching study was cross-sectional. Face-to-face interviews were conducted with Pasifika youth, parents and grandparents to investigate dietary diversity, that included both nutritious and discretionary food items and food groups over a 7 day period. Study setting was located in 2 large urban cities, New Zealand. Exploratory factor analyses were used to calculate food scores (means) from individual food items based on proportions consumed over the week, and weights were applied to calculate a standardised food score. The relationship between the level of acculturation and deprivation with dietary patterns was also assessed. RESULTS: Three distinctive dietary patterns across all participants were identified from our analyses. Healthy diet, processed diet and mixed diet. Mean food scores indicated statistically significant differences between the dietary patterns for older and younger generations. Older generations showed greater diversity in food items consumed, as well as eating primarily a 'healthy diet'. The younger generation was more likely to consume a 'processed diet'. There was significant association between acculturation and deprivation with the distinctive dietary patterns. CONCLUSION: Our investigation highlighted generational differences in consuming a limited range of food items. Identified dietary components may, in part, be explained by specific acculturation modes (assimilation and marginalised) and high socioeconomic deprivation among this particular study population.

A co-designed mHealth programme to support healthy lifestyles in Maori and Pasifika peoples in New Zealand (OL@-OR@): a cluster-randomised controlled trial.

BACKGROUND: The OL@-OR@ mobile health programme was co-designed with Maori and Pasifika communities in New Zealand, to support healthy lifestyle behaviours. We aimed to determine whether use of the programme improved adherence to health-related guidelines among Maori and Pasifika communities in New Zealand compared with a control group on a waiting list for the programme. METHODS: The OL@-OR@ trial was a 12-week, two-arm, cluster-randomised controlled trial. A cluster was defined as any distinct location or setting in New Zealand where people with shared interests or contexts congregated, such as churches, sports clubs, and community groups. Members of a cluster were eligible to participate if they were aged 18 years or older, had regular access to a mobile device or computer, and had regular internet access. Clusters of Maori and of Pasifika (separately) were randomly assigned (1:1) to either the intervention or control condition. The intervention group received the OL@-OR@ mHealth programme (smartphone app and website). The control group received a control version of the app that only collected baseline and outcome data. The primary outcome was self-reported adherence to health-related guidelines, which were measured with a composite health behaviour score (of physical activity, smoking, alcohol intake, and fruit and vegetable intake) at 12 weeks. The secondary outcomes were self-reported adherence to health-related behaviour guidelines at 4 weeks; self-reported bodyweight at 12 weeks; and holistic health and wellbeing status at 12 weeks, in all enrolled individuals in eligible clusters; and user engagement with the app, in individuals allocated to the intervention. Adverse events were not collected. This study is registered with the Australian New Zealand Clinical Trials Registry, ACTRN12617001484336. FINDINGS: Between Jan 24 and Aug 14, 2018, we enrolled 337 Maori participants from 19 clusters and 389 Pasifika participants from 18 clusters (n=726 participants) in the intervention group and 320 Maori participants from 15 clusters and 405 Pasifika participants from 17 clusters (n=725 participants) in the control group. Of these participants, 227 (67%) Maori participants and 347 (89%) Pasifika participants (n=574 participants) in the intervention group and 281 (88%) Maori participants and 369 (91%) Pasifika participants (n=650 participants) in the control group completed the 12-week follow-up and were included in the final analysis. Relative to baseline, adherence to health-related behaviour guidelines increased at 12 weeks in both groups (315 [43%] of 726 participants at baseline to 329 [57%] of 574 participants in the intervention group; 331 [46%] of 725 participants to 369 [57%] of 650 participants in the control group); however, there was no significant difference between intervention and control groups in adherence at 12 weeks (odds ratio [OR] 1·13; 95% CI 0·84-1·52; p=0·42). Furthermore, the proportion of participants adhering to guidelines on physical activity (351 [61%] of 574 intervention group participants vs 407 [63%] of 650 control group participants; OR 1·03, 95% CI 0·73-1·45; p=0·88), smoking (434 [76%] participants vs 501 [77%] participants; 1·12, 0·67-1·87; p=0·66), alcohol consumption (518 [90%] participants vs 596 [92%] participants; 0·73, 0·37-1·44; p=0·36), and fruit and vegetable intake (194 [34%] participants vs 196 [30%] participants; 1·08, 0·79-1·49; p=0·64) did not differ between groups. We found no significant differences between the intervention and control groups in any secondary outcome. 147 (26%) intervention group participants engaged with the OL@-OR@ programme (ie, set at least one behaviour change goal online). INTERPRETATION: The OL@-OR@ mobile health programme did not improve adherence to health-related behaviour guidelines amongst Maori and Pasifika individuals.

Antimicrobial stewardship using pharmacy data for the nurse-led school-based clinics in Counties Manukau District Health Board for management of group A streptococcal pharyngitis and skin infection.

AIM: To evaluate antimicrobial usage in the school-based clinics against operating guidelines. METHOD: Antimicrobial prescribing data (2014) from 10/18 participating pharmacies serving 14,153/23,588 primary school children of the programme were accessible. Prescriptions from 5/10 pharmacies were available for identifying type, amount, and indication of the medicine. One pharmacy serving a defined population (n=3,513) with single healthcare provider delivering the school programme was selected for detailed evaluation and identifying individuals receiving multiple treatments. RESULTS: Data from 10 pharmacies (n=7,889 prescriptions) showed 91.2% of prescriptions were for group A streptococcal-positive throat swab, 8.8% for skin infections. More detail from 5/10 pharmacies showed only 2% of group A streptococcal pharyngitis treatments (107/4,672) were not first-line (56 cephalexin and 51 rifampin prescriptions). Fusidic acid (159/452, 35.18%) or cephalexin (169/452, 37.39%) were most commonly used for skin infection. Analysis in the defined population showed <4% (151/4,325) of assessed skin conditions received antimicrobials, and only 6 individuals received more than one course of oral antimicrobial over the year. CONCLUSION: Antimicrobial administration demonstrates high compliance with the protocol. There was very limited use of second-line antimicrobials for recurrent pharyngitis. Most skin infections did not require antimicrobial treatment. Repeated antimicrobials for individuals were rare.

Understanding Pasifika youth and the obesogenic environment, Auckland and Wellington, New Zealand.

AIM: In New Zealand, the burden of obesity is greatest among Pacific people, especially in children and adolescents. We investigated the factors of the obesogenic environment that were indigenous to Pasifika youths' social-cultural context, their food purchasing behaviours, and associated anthropometric measures. METHODS: An exploratory study of 30 Pasifika youth aged 16-24 years in Wellington and Auckland, New Zealand. RESULTS: A large proportion of the participants were obese (mean body mass index: 31.0kg/m2; waistto-hip ratio: 0.84; waist-to-height ratio: 0.6), suggesting that the future health and wellbeing trajectory of the studied Pasifika youth is poor. Purchasing behaviours of food and snacks over a 7-day period provided meaningful insights that could be a useful future research tool to examine the role of their physical environment on food access and availability. CONCLUSIONS: From this exploratory study, we highlight the following: (i) the future health trajectory of Pasifika youth is poor. Developing the youths' healthy lifestyle knowledge may lend itself to developing culturally relevant intervention programmes; (ii) identifying the enablers and barriers within the Pasifika ontext of an obesogenic environment can provide very useful information; (iii) use of spatial analysis using purchased food receipts adds to the current knowledge base of obesity-related research, although this was an exploratory investigation. We need to address these highlights if we are to reverse the trend of obesity for this population.
