Depression, anxiety and worry in young Pacific adults in New Zealand during the COVID-19 pandemic.

OBJECTIVE: To measure symptoms of anxiety, depression and hopelessness in a sample of young Pacific adults living in Auckland, New Zealand during the 2020/2021 COVID-19 pandemic and identify protective factors. METHODS: Participants were 267 Pacific adults (58% female) who completed a survey online. Analyses included descriptive statistics, correlations, linear regression and symptom network analysis. RESULTS: Around 25% of the sample scored in the range for moderate to severe anxiety and 10% for moderate to severe depression on standard measures. Almost 40% indicated that they found the first lockdown very stressful and 55% noted that some members of their family found it stressful. Only 16% worried about COVID-19 and their future quite a bit or constantly, while another 25% worried sometimes. Self-compassion and Pacific Identity had moderate, negative correlations, and Worry about COVID-19 had weak positive correlations, with anxiety, depression, hopelessness and perceived stress. CONCLUSION: These results suggest that, while the prevalence of depression and anxiety are quite high among this population, fostering ethnic identity and self-compassion in Pacific children and adolescents might protect against developing depression and anxiety.

The Association Between Hearing Impairment and Problem Behaviors in 11-Year-Old Pacific Children Living in New Zealand.

OBJECTIVES: Hearing impairment in childhood is a serious disability that can impose a heavy social and economic burden on individuals and families. It was hypothesized that hearing loss or middle ear disease in 11-year-old Pacific children living in New Zealand would be associated with higher levels of engagement in (1) delinquent behaviors, and (2) clinical level internalizing and externalizing problem behaviors than Pacific children with no hearing loss or middle ear disease. Based on earlier findings, peer pressure, self-perception, physical punishment (slapping), sex, and ethnicity were controlled for in the association between hearing difficulties and behavioral outcomes. DESIGN: In the school setting, pure-tone audiometry and immittance audiometry assessments were used to establish the hearing level in 11-year-old Pacific children (n = 920). These children also completed multidisciplinary questionnaires, which included questions about involvement in delinquent behaviors, peer pressure, and self-perception. In the home setting, maternal reports were gathered on internalizing and externalizing problem behaviors in their offspring, their parenting style, and sociodemographic details. RESULTS: A significant effect of hearing level was detected for the odds of reporting mild delinquency versus no delinquency (odds ratio: 1.02, 95% CI: 1.00 to 1.05), and odds of moderate delinquency versus no delinquency (odds ratio: 0.97, 95% CI: 0.94 to 1.00). No significant effect was detected for hearing level and severe delinquency or internalizing or externalizing behavioral problems in the clinical range. Middle ear disease (abnormal tympanogram in the worse ear) was not significantly associated with delinquency at any level or with internalizing behaviors in the clinical range. However, children with middle ear disease were significantly less likely than all other participants to exhibit disruptive externalizing behavior in the clinical range. CONCLUSIONS: Relatively young children with hearing loss reported engagement in moderate levels of delinquency that represent serious antisocial and potentially violent acts. This finding provides evidence of the significant effect that hearing loss has on child behavior. This association between hearing loss and moderate delinquency requires ethnic-specific interventions that are targeted for maximum benefit at appropriate times in childhood to mitigate potentially long-term health, educational, and behavioral risks.

Hearing and ear status of Pacific children aged 11 years living in New Zealand: the Pacific Islands families hearing study.

OBJECTIVE: This study aimed to determine the prevalence of hearing loss and ear problems in Pacific children, and investigate current and past demographic, health and social factors potentially associated with hearing and ear problems. DESIGN: A cross-sectional observational study design nested within a birth cohort was employed. STUDY SAMPLE: Nine-hundred-twenty Pacific children aged 11 years were audiologically assessed. Using average hearing thresholds at 500, 1k and 2k Hz, 162 (18%) right and 197 (21%) left ears had ≥20 dB hearing loss. Hearing loss was mild (20-39 dB) in most cases; 2% of ears had moderate to moderate-severe (40-69 dB) hearing loss. However, only 101 (11%) children had normal peripheral hearing defined by passing hearing threshold, tympanogram and distortion product otoacoustic emission assessments. Those with confirmed middle ear disease at age 2 years had significantly increased odds of a non-Type A tympanogram (adjusted odds ratio: 2.00; 95% confidence interval: 1.56, 2.50) when re-assessed at age 11 years. CONCLUSIONS: Hearing loss, abnormal tympanograms, and auditory processing difficulties were present in many Pacific children. Interventions are also urgently needed to mitigate the effect of the longstanding ear disease likely to be present for many Pacific children.

Reducing emergency department presentations among chronically ill patients in Western Sydney: a key role for coordinated primary care.

Coordination of health services is thought to improve health outcomes for patients with chronic and complex illness; however, there is limited quantitative evidence for the effectiveness of coordinated care programs. HealthOne Mount Druitt (HOMD) is a coordinated care program operating in a disadvantaged area of Western Sydney, Australia. It operates as a combination 'virtual' and 'hub and spoke' model, with care coordination provided by liaison nurses. We aimed to determine whether there were changes in the number of emergency department (ED) presentations, length of stay, and community health referrals in the 12 months following enrolment in HOMD, compared to the 12 months prior. A quantitative survey was also conducted to determine the perspectives of service providers on key aspects of HOMD. Enrolment in HOMD was followed by reductions in both the number of ED presentations and the amount of time spent by patients in the ED. Community health referrals were increased, and the pattern of referral to different types of community health services was altered. This study provides quantitative evidence that a coordinated care intervention improves patient health outcomes.

Role of the GP liaison nurse in a community health program to improve integration and coordination of services for the chronically ill.

This paper explores the role of the General Practitioner Liaison Nurse (GPLN) in improving integration and coordination of services within Primary Health Care. This position can play a major role in care coordination and cultural change. The GPLN within HealthOne Mt Druitt (HOMD) identifies patients' needs and facilitates communication, case conferencing and care coordination between health and other providers. The priority areas of children and their families at risk or with significant unmet needs, and chronic aged and complex care, were identified as target areas. This paper focuses on the GPLN within the chronic aged and complex care service model. The GPLN within HOMD was able to improve coordination and integration of services for patients of the facility. Activities included organising multidisciplinary services and addressing psychosocial issues. Patients and community health staff identified the importance of the role for improving coordination and integration of services. Decision and policy makers saw the position as vital to the implementation, operation and sustainability of HOMD.

Pacific Islands Families Study: Patterns of Intimate Partner Violence Among Pacific Mothers.

Intimate partner violence (IPV) is a widespread social problem affecting all populations regardless of gender, race, and socioeconomic status. The aims of this study were to examine (a) patterns of IPV among Pacific women living in New Zealand and (b) the risk and protective factors associated with IPV perpetration and victimization. As part of the longitudinal Pacific Islands Families (PIF) Study, maternal interviews, which included reports about IPV, acculturation, and sociodemographic characteristics, were administered at phases 6 weeks, 2, 6, 11, and 14 years postpartum. Age had a significant effect on perpetration of both minor and severe perpetration of IPV, and on being a victim of minor IPV. However, no significant effect was found for severe victimization. Cultural alignment also had a significant effect on perpetration of IPV with Pacific mothers who were strongly aligned to their traditional Pacific culture being significantly less likely to report minor or severe IPV perpetration compared with Pacific mothers who were closely aligned to western culture. Single mothers reported significantly more minor victimization, and those mothers who were more highly educated and were in a higher income bracket were significantly less likely to report severe physical IPV victimization. These findings can inform the timing and targeting of culturally appropriate violence prevention efforts in adolescence and young adulthood that focus on the development of healthy intimate partner relationships and effective methods of conflict resolution.

Environmental Influences on the Behavioural and Emotional Outcomes of Children: A Network Analysis.

BACKGROUND: Intellectual developmental disorders are a serious source of health morbidity with negative consequences for adults as well as children. However, there is limited evidence on the environmental, trace element, behavioural, and emotional outcomes in children. Here, we investigated whether there is any association between child behaviour and emotional outcomes and micronutrients using network analysis. METHODS: A cross-sectional study was conducted in 9-year-old children within a Pacific Island Families study birth cohort. Elemental concentration was determined in children's toenails after acid digestion and analysed using inductively coupled plasma mass spectrometry. We used network analysis to identify closely associated trace elements and tested the directions and strength of these trace elements. MANCOVA were used to identify the significant associations between individual elements and the behavioural/emotional function of the children using the children behaviour checklist (CBCL). At the final step, quantile regression analysis was used to assess and quantify the identified associations between CBCL function scores and manganese, adjusted by sex, ethnicity, and standardized BMI. RESULTS: Three major nutrient networks were identified. In the Mn network, Mn was strongly positively associated with Al (0.63) and Fe (r = 0.65) and moderately associated with Pb (r = 0.45) and Sb (r = 0.42). Al was also strongly associated with Fe (r = 0.9). Children in the second or third clinical group, with an elevated externalized CBCL score, had a much higher mean and median level of Mn as compared to the normal range group. The aggression score was significantly associated with Mn concentration and sex. Higher Mn concentrations were associated with a higher aggression score. A 1 ug/g unit increase in Mn was associated with a 2.44-fold increase (95% confidence interval: 1.55-4.21) in aggression score, and boys had higher median aggression score than girls (difference: 1.7, 95% CI: 0.9-2.8). Attention and rule breaking scores were both significantly associated with Mn concentration. Higher Mn concentrations were associated with higher attention behaviour problem and rule breaking scores. A 1 ug/g unit increase in Mn was found to be associated with a 1.80-fold increase (95% confidence interval: 1.37-2.82) in attention score, and a 1.46-fold increase (95% confidence interval: 1.01-1.74) in the rule breaking score. Thought score was not significantly associated with Mn concentration (p = 0.13) but was significantly lower in boys (p = 0.004). CONCLUSIONS: Exceeding Mn levels is potentially toxic and has been identified to be associated with worse externalized children's behavioural health and emotional well-being. Future studies are necessary to find the exposure paths so that advice shall be provided to family and care providers in public health and environmental protection.

Barriers to older Pacific peoples’ participation in the health-care system in Aotearoa New Zealand.

Introduction Participation in the health-care system is a key component of healthy ageing strategies. The number of Pacific people aged ≥65 years in Aotearoa New Zealand will increase significantly over the next decade. Addressing the considerable health inequities and unmet need for care Pacific Island people experience when compared to other ethnicities in Aotearoa New Zealand should be a priority. Aim To identify barriers to older Pacific people's participation in the health-care system in Aotearoa New Zealand. Methods A participatory action research design was utilised. In total, 104 Pacific co-researchers contributed to focus groups using Talanoa , a traditional method of conversational dialogue deeply rooted in Pacific Island culture. Data were collected in Pacific Island languages from storytelling and conversations shared within the focus groups. Data were translated into English and analysed using a collaborative approach. Results Three main themes captured older Pacific peoples' barriers to participation in the health-care system: accessing health care; relationships with health-care providers; and understanding the health-care system. Discussion Older Pacific people have the capacity to influence locally driven programmes to be more responsive to their needs and aspirations. Improving older Pacific peoples' participation in health care will require a commitment to partnership and inter-sectoral collaboration identified in recent ageing strategies. The findings will inform local communities, and policy and practice aimed at improving the health and wellbeing of Pacific peoples who are ageing in Aotearoa New Zealand.

Acculturation of Pacific mothers in New Zealand over time: findings from the Pacific Islands Families study.

BACKGROUND: The epidemiological investigation of acculturation has often been hampered by inconsistent definitions and measurement, and methodological short-comings. Adopting a bi-directional model, with good theoretical and psychometric properties, this study aimed to describe the temporal, ethnic and socio-demographic influences of acculturation for a group of Pacific mothers residing in New Zealand. METHODS: Pacific mothers of a cohort of Pacific infants born at a large tertiary hospital in South Auckland in 2000 were interviewed at 6-weeks, 4-years and 6-years postpartum. At each measurement wave a home interview lasting approximately 90 minutes was conducted with each mother. Adapting the General Ethnicity Questionnaire, two scales of acculturation were elicited: one measuring New Zealand cultural orientation (NZAccult) and one measuring Pacific Islands cultural orientation (PIAccult). Acculturation scores were standardised and analysed using random intercept polynomial and piecewise mixed-effects regression models, accounting for the longitudinal nature of the repeated measured data. Mothers who immigrated to New Zealand and those who lived their lives in New Zealand were investigated separately. RESULTS: Overall, 1276 Pacific mothers provided 3104 NZAccult and 3107 PIAccult responses over the three measurement waves. Important and significant differences were observed in both bi-directional acculturation measures between the two maternal groups studied. New Zealand cultural orientation increased, on average, linearly with years lived in New Zealand both for immigrant mothers (0.013 per year, 95% CI: 0.012, 0.014), after adjusting for maternal age, and for mothers who lived their lives in New Zealand (0.008 per year, 95% CI: 0.06, 0.010). Immigrant mothers maintained their Pacific cultural orientation for, on average, 12 years before it began to linearly decrease with each year lived in New Zealand thereafter (-0.009 per year, 95% CI: -0.010, -0.008), after adjusting for maternal age. Mothers who lived their lives in New Zealand had a Pacific orientation that was, on average, unchanged regardless of the number of years lived in New Zealand. Significant ethnic and socio-demographic variations were noted. CONCLUSIONS: Understanding the patterns and trajectories of acculturation over time, and its key determinants, is necessary for the development of appropriate targeted health policy and care in typically vulnerable and marginalised immigrant populations.

Pacific and English Language Fluency and Mental Disorder Symptom Indications Among Pacific Mothers in New Zealand: Findings From the Pacific Islands Families Study.

Within New Zealand (NZ), Pacific people experience higher prevalence of mental disorder than non-Pacific people. Bilinguals are believed to have psychological advantages over monolinguals, although the empirical evidence base is equivocal. A prospective cohort of Pacific mothers was studied at 6 weeks (n = 1272), 1-year (n = 1135), and 2-year (n = 1059) postpartum. At 6 weeks, 343 (27.0%) mothers were fluent in both Pacific and English languages, 519 (40.8%) only fluent in Pacific language(s), and 410 (32.2%) only fluent in English. Over assessment waves, 16.0%, 12.5%, and 8.7% of mothers had mental disorder symptom indications. In adjusted generalized estimating equation analysis, mothers speaking English only had odds of mental disorder symptom indication of 2.24 as compared to bilingual mothers, while those who spoke Pacific language(s) only had odds of 1.52. Supporting Pacific and English languages within NZ may confer mental health benefits to new Pacific mothers and potentially others.

Visual impairment and its correction among Pacific youth in Aotearoa: findings from the Pacific Islands Families Study.

AIM: Childhood visual impairment has a life-long impact that, with early access to eyecare, is largely avoidable. We aimed to understand visual impairment and its correction among Pacific youth in Aotearoa New Zealand. METHOD: The Pacific Islands Families Study is a birth cohort study that tracks an original sample of 1,398 Pacific children born at Middlemore Hospital (Auckland). This analysis focuses on assessed visual acuity (at 9- and 18-years, using 0.3logMAR or 6/12 as the cut-off for visual impairment) and participants' self-reports about accessing eyecare services. RESULTS: Less than a fifth of children (111/729, 15.2%) and teens (86/457, 18.8%) reported having sought eyecare. The percentage of participants with refractive correction was 3.6% (32/887) at 9-years and 14.3% (66/463) at 18-years. At 9-years, 1.9% of children (16/853) had visual impairment in one eye only, and 0.9% (8/853) had visual impairment impacting both eyes. By 18-years these values increased to 7.9% (36/456) and 4.2% (19/456), respectively. Among those with visual impairment, most children (15/24, 62.5%) and teens (32/55, 58.2%) reported they did not have refractive correction. CONCLUSION: Although prevalence of visual impairment is relatively low compared to non-Pacific youth, much of the reported impairment appears to be avoidable with improved eyecare.

Impact of current and past intimate partner violence on maternal mental health and behaviour at 2 years after childbirth: evidence from the Pacific Islands Families Study.

OBJECTIVE: The present study examined the association between maternal intimate partner violence (IPV) at 6 weeks and 24 months postpartum and maternal health problems in a cohort of Pacific families with 2-year-old children in New Zealand. METHODS: Data were gathered from the Pacific Islands Families Study. Mothers of a cohort of Pacific infants born in Auckland, New Zealand during 2000 were interviewed when the children were 6 weeks and 24 months of age. There were 828 mothers cohabiting in married or de facto partnerships who completed measures of IPV, mental health, and health-related behaviour such as smoking and high-risk alcohol use at both data points. The main statistical method used was logistic regression analysis. RESULTS: Compared to mothers who did not experience physical violence at either data point, the odds of reporting psychological distress were 2.42 (95% confidence interval (CI) = 1.07-5.44) for those experiencing physical violence at 6 weeks only, 3.47 (95%CI = 1.75-6.86) for those experiencing physical violence at 24 months only, and 3.84 (95%CI = 1.78-8.30) for those experiencing physical violence at both data points after controlling for sociodemographic factors. Mothers experiencing verbal aggression or physical violence at both data points were more likely to report smoking or high-risk alcohol use at 24 months than those who did not, but the associations were no longer significant after controlling for sociodemographic factors. CONCLUSION: Being a victim of intimate partner physical violence at any time (past, recent and repeated) may contribute to an increase in maternal psychological distress. Health-related behaviours such as smoking and high-risk alcohol use at 24 months postpartum may to some degree be attributable to repeated victimization of physical violence and verbal aggression, but the relationships are not convincing and deserve further research in longitudinal studies.

Exposure to Toenail Heavy Metals and Child Behavior Problems in Nine-Year-Old Children: A Cross-Sectional Study.

Behavioral problems are multifactorial and includes perinatal, maternal, family, parenting, socio-economic and personal risk factors, but less is known about the association of postnatal heavy metals on children's behavioral problems in Pacific Island children. METHODS: A cohort of eligible nine-year-old children within a Pacific Island Families longitudinal study were recruited for a cross-sectional study. Child behavior problems were assessed using the child behavior checklist. Heavy metals (including Ni, Cu, Pb, Al, Cr and Cd) were determined in toenails, after acid digestion and analyzed using inductively coupled plasma mass spectrometry. Other factors such as lifestyle (smoking in pregnancy), health outcomes (obesity, health status), demographics (gender, ethnicity, parents' marital status) and socioeconomic status (household income levels) were also collected. The statistical analysis included t-tests for independent sample and Mann-Whitney U-test, and chi-square or Fisher's exact tests of independence for comparisons of the proportions. Regression models tested the hypothesized risk factors for behavior outcomes. RESULTS: This observational study enrolled 278 eligible Pacific Island children living in Auckland, New Zealand. The prevalence of behavioral problems in the clinical range was high (22%) but there was no significant association between heavy metals in toenails and adverse behavioral outcomes. CONCLUSION: Regular monitoring and assessments of children for environmental risk factors, as well as social and lifestyle factors for behavior problems, continues. Alternative indicators of exposure to heavy metal should be evaluated.

Relating intimate partner violence to heath-care utilisation and injuries among Pacific children in Auckland: the Pacific Islands Families Study.

AIM: Despite well-known emotional and behavioural sequela, few studies investigate health-care utilisation and injury impacts of children exposed to intimate partner violence (IPV). This study examines the association between mothers' IPV experience and general practitioner (GP) and hospital presentations by their children within the first 6 years of life. METHODS: In 2000, a cohort of Pacific infants born in Auckland was established. At 6 weeks, 2 years and 6 years post-partum, maternal home interviews were conducted and IPV experience elicited using the Conflict Tactic Scale, together with reports of children's GP and hospital visitations. RESULTS: At 6 weeks, 2 years and 6 years, 1098, 921 and 799 participating mothers were in intimate relationships. Severe physical IPV was reported by 22.1, 23.0 and 7.1% of mothers, respectively, and minor IPV was reported by another 18.7, 16.9 and 6.1%, respectively. Compared with children without maternal physical IPV exposure, children of mothers disclosing severe physical IPV were 1.19 (95% confidence interval (CI): 1.08-1.31) times as likely to visit GPs, and children of mothers disclosing minor physical IPV were 1.13 (95% CI: 1.02-1.25) times as likely to visit GPs, after adjusting for socio-demographic, maternal mental health and other confounding factors. No significant association was found between maternal IPV and children's hospital visits, or GP or hospital visits for injury. CONCLUSIONS: IPV is common for many mothers of Pacific children, and is associated with significantly more GP visits for exposed children. Identification of maternal IPV during mothers' and children's GP and hospital visits may help guide services to prevent future presentations to children.

Do perceptions of neighbourhood problems contribute to maternal health?: findings from the Pacific Islands Families study.

Research suggests that physical and social aspects of the neighbourhood have a bearing on our well-being. As part of the Pacific Islands Families Study, this study examined maternal perceptions and socio-demographic determinants of neighbourhood problems and their association with mental health. The main problems reported centred on noise, pollution and safety matters. Ethnicity, deprivation and alcohol consumption were the best predictors of greater perceived neighbourhood problems. Adjusted analyses showed that those reporting greater neighbourhood problems were almost twice as likely as those reporting fewer problems to have psychological morbidity. Mothers with high deprivation scores were 7.3 times more likely to have psychological morbidity. Findings suggest that neighbourhood quality and socio-economic position are important contributors to mental health. Negative effects on health are likely to derive from exposure to pollutants and from problem features in the neighbourhood acting as sources of psychosocial stress and barriers to health promoting activities. Improvements to services and regulations may contribute to health gains.

Mercury Exposure in Mother-Children Pairs in A Seafood Eating Population: Body Burden and Related Factors.

Background: Mercury is a neurotoxin that affects neurodevelopment in children; however, its association at the lowest concentration is not clear. The main objective of this study is to measure and evaluate mercury concentrations in mother-child pairs and its association demographics, lifestyle, and dietary factors within the Pacific Island Families living in Auckland, New Zealand. Methods: Mercury exposure was assessed in a sub-sample of mother-child pairs who were a part of the Pacific Island Families birth cohort, in Auckland, New Zealand at the 6-year phase. Hair samples were collected from both mothers and their children to determine mercury concentrations. Total mercury was measured using inductively coupled plasma mass spectrometry for hair samples. An interviewer-based reliable food frequency questionnaire (FFQ) examined the frequency of seafood by all the participants. Other variables such as sociodemographic (ethnicity and gender), lifestyle factors (income, education, and smoking status) and health outcomes (child behaviour and obesity) were also collected. Results: In this study, 41% of both mothers and their children had mercury concentrations above the US Environmental Protection Agency (EPA) recommended value of 1 µg/g. Most of the participants ate fish 3 or more times a week. A significant correlation was observed between mother and child hair mercury concentrations (Spearman Rho 0.79 (95% confidence interval (CI): 0.65, 0.88)). Conclusions: Mercury levels in children can be affected by their mothers' levels due to similar eating patterns.

Household Smoking Status and Heavy Metal Concentrations in Toenails of Children.

There is limited evidence on the distribution of heavy metals and its association with secondhand smoking (SHS) within Pacific Island children living in New Zealand. Certain heavy metals such as cadmium (Cd), lead (Pb), and aluminum (Al) bioaccumulates in the body and can deteriorate health in both children and adults. Others, such as chromium (Cr) and nickel (Ni) in trace amounts are necessary but become toxic at high levels. Exposure routes of these elements include food, water, and air. The purpose of this study was to identify the distribution of toxic metal concentrations and its possible correlation with SHS within the Pacific Island children. A sub-sample of children within Pacific Island families longitudinal study, at the nine-year phase, who were living in the New Zealand city of Auckland were invited to participate, (n = 278). Toenails were used as a biomarker to determine Cr, Pb, Cd, Cu, Ni, and Al concentration using inductively coupled plasma mass spectrometry. Reliable and validated questionnaires were used for demographics, lifestyle, and health outcome variables. Significant differences between household smoking status and ethnicity, as well as parents' marital status, were observed (p < 0.05). There was no statistical difference in heavy metal concentrations in smoking versus non-smoking households. However, Cr, Pb, Cd, Cu, and Ni concentrations were all higher than the required optimal health value in both groups. A high concentration of heavy metals was observed in these children that exceeded the value required for optimal health, although no significant difference in heavy metals with regards to secondhand smoking was observed. SHS was associated with children's ethnicity and parental marital status, but not with household income levels or maternal education.

The Importance of Pedestrian Network Connectivity for Adolescent Health: A Cross-sectional Examination of Associations between Neighbourhood Built Environments and Metabolic Health in the Pacific Islands Families Birth Cohort Study.

The research aim was to investigate associations between objectively-assessed built environment attributes and metabolic risk in adolescents of Pacific Islands ethnicity, and to consider the possible mediating effect of physical activity and sedentary time. Youth (n = 204) undertook a suite of physical assessments including body composition, blood sampling, and blood pressure measurements, and seven day accelerometry. Objective measures of the neighbourhood built environment were generated around individual addresses. Logistic regression and linear modelling were used to assess associations between environment measures and metabolic health, accounting for physical activity behaviours. Higher pedestrian connectivity was associated with an increase in the chance of having any International Diabetes Federation metabolic risk factors for males only. Pedestrian connectivity was related to fat free mass in males in unadjusted analyses only. This study provides evidence for the importance of pedestrian network connectivity for health in adolescent males. Future research is required to expand the limited evidence in neighbourhood environments and adolescent metabolic health.

Maternal intimate partner violence and behavioural problems among Pacific children living in New Zealand.

AIMS: To examine (1) the association between maternal intimate partner violence (IPV) perpetration and victimisation and behavioural problems among two- and four-year-old Pacific children, and (2) the socio-demographic and parenting factors that may impact on this association. DESIGN: Mothers of the Pacific Islands Families (PIF) cohort of Pacific infants born in New Zealand during 2000 were interviewed when the children were two and four years of age. This data set was based on mothers who were cohabiting in married or de-facto partnerships (N = 920) and who completed measures of IPV at the two-year assessment point and the Child Behaviour Checklist (CBCL) at the two-or four-year assessment points. Of these, 709 mothers completed the CBCL at both assessment points. RESULTS: There were no significant associations between IPV and the prevalence rates of clinically relevant cases of behavioural problems in the two-year-old child cohort. However, the prevalence rates of clinically relevant internalising, externalising and total problem cases were significantly higher among four-year-old children of mothers who reported severe perpetration of IPV. The odds of being in clinical range of internalising were 2.16 times higher for children of mothers who were perpetrators of severe physical violence than for those children of mothers who were not, and for externalising and total problems they were 2.38 and 2.36 times higher respectively. Socio-demographic and parenting factors did not significantly influence the association between IPV and child behaviour problems. CONCLUSION: These findings contribute to the complex picture of the consequences that exposure to parental violence may have on the behaviour of young children. The effectiveness of preventative strategies may be maximised if implemented in these early years before such problems become entrenched and lead on to future behavioural problems and impaired family relationships.

Maternal smoking during pregnancy and behaviour problems in a birth cohort of 2-year-old Pacific children in New Zealand.

AIM: The present study investigated associations between maternal smoking during pregnancy and child behaviour problems in a cohort of Pacific Islands two-year-old children in New Zealand. STUDY DESIGN: Data were gathered as part of the Pacific Islands Families (PIF) Study. Mothers of a cohort of 1398 Pacific infants born in South Auckland, New Zealand were interviewed when their children were six-weeks, 12 and 24 months of age. Within the context of a wider interview, data regarding cigarette smoking during pregnancy was obtained from 1038 biological mothers at the six-week interview and reports of child behaviour using the Child Behaviour Checklist were gathered when the children were 24 months old. RESULTS: The prevalence rates of clinically relevant cases were higher in children of smokers compared to non-smokers for internalising (22.6% versus 15.2%), externalising (9.6% versus 5.7%) and total problem scores (20% versus 12.4%). Following adjustment for potential confounding factors, smoking was associated with a moderately increased prevalence of total behaviour problems (OR=1.75, 95% CI=(1.12, 2.74); p=0.015). For internalising scores, the effects of smoking appeared to be raised for children of non-partnered mothers (OR=3.35, 95% CI=(1.29, 8.67); p=0.013). For externalising scores, smoking appeared to have a greater detrimental effect on girls (OR=2.37, 95% CI=(1.12, 5.04); p=0.024). CONCLUSIONS: Findings indicate there are significant effects of prenatal tobacco exposure on problem behaviour among young children. Smoking is a modifiable factor worthy of increased early preventive efforts.
