Clinical and cost-effectiveness of an online-delivered group-based pain management programme in improving pain-related disability for people with persistent pain-protocol for a non-inferiority randomised controlled trial (iSelf-help trial).

INTRODUCTION: Persistent non-cancer pain affects one in five adults and is more common in Maori-the Indigenous population of New Zealand (NZ), adults over 65 years, and people living in areas of high deprivation. Despite the evidence supporting multidisciplinary pain management programmes (PMPs), access to PMPs is poor due to long waiting lists. Although online-delivered PMPs enhance access, none have been codesigned with patients or compared with group-based, in-person PMPs. This non-inferiority trial aims to evaluate the clinical and cost-effectiveness of a cocreated, culturally appropriate, online-delivered PMP (iSelf-help) compared with in-person PMP in reducing pain-related disability. METHODS AND ANALYSIS: Mixed-methods, using a modified participatory action research (PAR) framework, involving three phases. Phase I involved cocreation and cultural appropriateness of iSelf-help by PAR team members. Phase II: The proposed iSelf-help trial is a pragmatic, multicentred, assessor-blinded, two-arm, parallel group, non-inferiority randomised controlled trial. Adults (n=180, age ≥18 years) with persistent non-cancer pain eligible for a PMP will be recruited and block randomised (with equal probabilities) to intervention (iSelf-help) and control groups (in-person PMP). The iSelf-help participants will participate in two 60-minute video-conferencing sessions weekly for 12 weeks with access to cocreated resources via smartphone application and a password-protected website. The control participants will receive group-based, in-person delivered PMP. Primary outcome is pain-related disability assessed via modified Roland Morris Disability Questionnaire at 6 months post intervention. Secondary outcomes include anxiety, depression, stress, pain severity, quality of life, acceptance, self-efficacy, catastrophising and fear avoidance. Data will be collected at baseline, after the 12-week intervention, and at 3 and 6 months post intervention. We will conduct economic analyses and mixed-method process evaluations (Phase IIA). ETHICS AND DISSEMINATION: The Health and Disability Ethics Committee approved the study protocol (HDEC18/CEN/162). Phase III involves dissemination of findings guided by the PAR team as outcomes become apparent. TRIAL REGISTRATION NUMBER: ACTRN 12619000771156.

The experiences of young people with chronic illness in New Zealand: A qualitative study.

BACKGROUND: Around 10% of young people suffer from chronic health conditions, and their health care needs are different from those of children or adults. Most research about young people's chronic illness focuses on specific conditions, on younger children's experience, and on the perspectives of parents. This study explored the experiences of young people with two very different chronic conditions (asthma and cancer) and their perception of the New Zealand health system's response to their needs. METHODS: This was a collaborative research process where eight young co-researchers who had asthma or cancer were employed to work alongside the research team to develop protocols, interview peers, and assist with analysis. The challenges of this process are described in the article. Twenty-one young people between ages 15 and 27 from two urban areas of New Zealand participated in semistructured open-ended interviews about their health care experiences. Sixteen participants were female, and five male. Eleven of the participants had finished cancer treatment (with an average of 3.6 years since diagnosis), and 10 had asthma. Purposeful sampling meant that 80% of the participants with asthma were identified as Maori and the other participants identified with a range of other ethnic groups. Data were thematically coded, and coresearchers were consulted to derive the ultimate findings. RESULTS: Chronic illness disrupted the trajectory of young people's lives and had significant effects on their relationships. The New Zealand health system generally did not respond well to the needs of these young people, but many encountered extraordinary individuals who supported them effectively. The experiences of some indigenous participants indicate that health professionals require effective cultural competence training. CONCLUSIONS: This study provides insights into how young people with very different conditions experience the health system. Young people should be consulted and actively included in decision making about making health systems responsive to their diverse needs.

Hair nicotine at 15 months old, tobacco exposure and wheeze or asthma from 15 months to 6 years old.

OBJECTIVE: To investigate the relationship between hair nicotine levels at 15 months of age and prior parent-reported smoking exposure, and the risk of wheezing and current asthma from 15 months to 6 years of age. STUDY DESIGN: We measured hair nicotine levels at 15 months of age in 376 of 535 infants enrolled in a prospective birth cohort in Christchurch, New Zealand. We obtained detailed information from parents about smoking exposure during pregnancy and in the home at 3 and 15 months of age. Data for demographics, wheezing, and asthma were obtained from yearly questionnaires up to age 6 years. We assessed hair nicotine levels in relation to reported smoke exposure in pregnancy and up to age 15 months, and the association between high levels of hair nicotine and annual reports of current wheeze and current asthma using multiple logistic regression. RESULTS: Hair nicotine increased with numbers of smokers and daily cigarettes smoked at home, and was also strongly associated with smoking in pregnancy. High level of hair nicotine was associated with increased risk of wheeze (Odds ratio 2.30, P = 0.001) and, though not significant, of current asthma (Odds ratio 2.02, P = 0.056) at 15 months of age, after controlling for socio-economic status, ethnicity, body mass index, respiratory infections in the first 3 months of life, and duration of exclusive breastfeeding. At older ages the associations were non-significant. CONCLUSION: In children aged 15 months hair nicotine level was related to smoking exposure, and was associated with increased risk of wheeze and asthma.

Vitamin D status of newborns in New Zealand.

Recognition of the important non-skeletal health effects of vitamin D has focused attention on the vitamin D status of individuals across the lifespan. To examine the vitamin D status of newborns, we measured serum levels of 25-hydroxyvitamin D (25(OH)D) in the cord blood of 929 apparently healthy newborns in a population-based study in New Zealand, a country at 41 °S latitude, with strong anti-skin cancer (sun avoidance) campaigns and without vitamin D food fortification. Randomly selected midwives in two regions recruited children. The median cord blood level of 25(OH)D was 44 nmol/l (interquartile range, 29-78 nmol/l). Overall, 19 % of newborns had 25(OH)D levels < 25 nmol/l and 57 % had levels < 50 nmol/l; only 27 % had levels of 75 nmol/l or higher, which are levels associated with optimal health in older children and adults. A multivariable ordinal logistic regression model showed that the strongest determinants of low vitamin D status were winter month of birth and non-European ethnicity. Other determinants of low cord blood 25(OH)D included longer gestational age, younger maternal age and a parental history of asthma. In summary, low levels of vitamin D are common among apparently healthy New Zealand newborns, and are independently associated with several easily identified factors. Although the optimal timing and dosage of vitamin D supplementation require further study, our findings may assist future efforts to correct low levels of 25(OH)D among New Zealand mothers and their newborn children.

Breastfeeding protects against adverse respiratory outcomes at 15 months of age.

The relationship between breastfeeding, respiratory and other allergic disorders has been controversial. Our aim was to investigate the relationships between breastfeeding, respiratory outcomes, eczema and atopy at 15 months of age in a prospective birth cohort in New Zealand. A total of 1105 children were enrolled at birth, and 1011 (91.2%) were followed up at 15 months. Logistic regression was used to model associations between breastfeeding duration and respiratory outcomes, eczema and atopy after adjusting for relevant confounding variables: ethnicity, socio-economic status, parity, body mass index, smoking in pregnancy, gender and respiratory infections in the first 3 months of life. Breastfeeding was associated with a significant reduction in the risk of adverse respiratory outcomes at 15 months. After adjustment for confounders, each month of exclusive breastfeeding reduced the risk of doctor-diagnosed asthma by 20% (odds ratio 0.80, 95% confidence interval 0.71 to 0.90), wheezing by 12% (0.88, 0.82 to 0.94) and inhaler use by 14% (0.86, 0.78 to 0.93). Associations for both exclusive and additional breastfeeding durations, and respiratory outcomes remained independently significant when modelled simultaneously. Although independently associated with all respiratory outcomes, adjusting for parental history of allergic disease or maternal history of asthma did not alter our findings. Breastfeeding was not associated with eczema or atopy at 15 months. In conclusion, there was a significant protective effect of breastfeeding on infant wheezing and other adverse respiratory outcomes that may be early indicators of asthma in New Zealand children.
