Identifying opportunities to strengthen school food environments in the Pacific: a case study in Samoa

Background Despite global recommendations to prioritise policies that create healthy food environments within education institutions, the implementation of effective healthy school food policies has proved challenging for many countries. This study examined the experience of Samoa subsequent to the 2012 introduction of a stronger policy to improve the healthiness of school food environments. Our aim was to identify opportunities to strengthen healthy school food policy implementation in Samoa and other comparable contexts. Methods We used a qualitative case study approach, underpinned by policy science theory. In 2018, we conducted in-depth semi-structured interviews with 30 informants, coupled with analysis of relevant documents, to generate a detailed understanding of the relevant policy implementation processes in Samoa, and the perspectives and capacities of key implementation actors. Data collection and analysis were guided by the Health Policy Analysis Triangle, supplemented by other policy theories relevant to policy process. Results Samoa’s school food policy operationalizes international ‘best practice’ recommendations. We found health policymakers and leaders in Samoa to be strongly committed to improving school food environments. Despite this, there continued to be challenges in ensuring compliance with the school nutrition standards. Key issues that negatively impacted the policy’s effectiveness were the lack of priority given to school food by stakeholders outside of health, the high prevalence of unhealthy food in the areas immediately surrounding schools, vendor knowledge and capacity, and the high degree of agency exercised by actors in and around the school. We noted several opportunities for policies to be effectively implemented and sustained. Respondents identified community-level leaders as potentially pivotal stakeholders, particularly where school governance arrangements draw heavily on community representation. Conclusions Sustained and effective implementation of healthy school food policies requires continued engagement from political and community leaders, beyond initial commitment. There is potential to capitalize on political will for diet-related NCD prevention by more clearly demonstrating the institutional and operational requirements for effective and sustained implementation. Strong incentives for compliance and effective enforcement mechanisms are also likely to be crucial to success

Scoping review protocol of multicomponent interventions to address cardiometabolic disease risk among Pacific Islander children.

IntroductionMulticomponent interventions can reduce cardiometabolic disease (CMD) risk factors in childhood; however, little synthesis of the literature has taken place in the Pacific region. Pacific Islanders experience a disproportionately high prevalence of CMD risk factors, yet interventions have been slow to reach many communities. We present this protocol for a scoping review to identify and summarize existing multicomponent interventions to address CMD risk in Pacific Islander children.Materials and methodsEligible interventions will (1) address CMD risk factors (including but not limited to obesity, hyperglycemia, dyslipidemia, elevated blood pressure, and/or health behaviors) in 2-to-12-year-old Pacific Islander children, and (2) be multi-component (including at least two lifestyle/behavior change strategies to address CMD risk factors). To investigate existing interventions for adaptation and potential use in Pacific Islander communities, we will search Scopus, MEDLINE ALL (Ovid), EMBASE (Ovid), Yale-licensed Web of Science Core Collection, Cochrane Library, CINAHL (EBSCOhost), ProQuest Dissertations & Theses Global, Global Health (EBSCO), non-indexed Pacific journals, grey literature, government reports, and clinical trial registrations. The Joanna Briggs Institute Manual for Evidence Synthesis and the Preferred Reporting Items for Scoping Reviews will guide data extraction, evidence mapping, synthesis, and reporting of information including study population, intervention components, behavioral changes, health and implementation outcomes, theoretical frameworks, and evaluation measures.Ethics and disseminationFormal ethical approval is not required. The dissemination strategy will include peer-reviewed journal publications and presentations. Synthesis of existing multicomponent interventions for Pacific Islander children will help to identify best practices that could be replicated, adapted, or combined

Nutrient intake among Samoan children aged 2–4 years in 2015

Background: Young children are particularly vulnerable to malnutrition as nutrition transition progresses. The aim of this study was to examine the adequacy of macro- and micronutrient intake among 2–4.99-year-old Samoan children. Methods: Child dietary intake was measured using a 117-item food frequency questionnaire (FFQ) with a 30-day reference period. Daily total energy and nutrient intake was calculated by multiplying the frequency of daily consumption by the nutrient content of a fixed, standard portion size. Adequacy of macro- and micronutrient intake was determined using age-specific US Dietary Guidelines. Results: Most children met or exceeded recommendations for carbohydrate, fat and protein intake. More than half of the sample were not meeting the Recommended Dietary Allowance (RDA) for calcium (59.0%), 44.6% were not meeting RDA for potassium and intake of vitamin A and E was inadequate among 25.9% and 25.6%, respectively. Eighty per cent of children exceeded the tolerable upper limit for sodium. Adequacy of intake varied by age and census region of residence. Conclusion: Since inadequate dietary micronutrient intake was more common among older children (4–4.99 years) and those in the rural region, intervention should be targeted at those groups

Longitudinal assessment of childhood dietary patterns: Associations with body mass index z-Score among children in the Samoan Ola Tuputupua\u27e (Growing Up) cohort

Background: Intervention strategies to prevent childhood obesity in the Pacific Islands encourage eating a variety of local and traditional foods, but context-specific data to support this approach are limited. The objective was to assess the association between 2-year adherence to modern and neotraditional dietary patterns and body mass index z-scores (BMIz) among Samoan children. Methods: A convenience sample of 214 Samoan biological mother-child dyads who participated in the Ola Tuputupua'e “Growing Up” cohort study in 2015 and 2017 was included. At each time point, modern and neotraditional dietary patterns were identified using food frequency data and factor analysis. Children were assigned to categories based on diet pattern adherence: consistently high, high to low, low to high, and consistently low. Associations between 2-year adherence to dietary patterns, BMIz (in 2017 and 2015–2017), and weight and height z-scores were examined using linear models adjusted for potential confounders. Results: Consistently high adherence to the modern pattern was associated with a 0.36 standard deviation (SD)-adjusted change in BMIz between 2015 and 2017 (95% confidence interval [CI]: 0.04–0.69, p = 0.03). While the estimates for the individual components of BMI were imprecise, on average, children with consistently high adherence to the modern pattern had a 0.13 SD greater change in weight z-score (95% CI: −0.10 to 0.37) and 0.15 SD lower change in height z-score (95% CI: −0.43 to 0.13). The change in BMIz between 2015 and 2017 did not significantly differ by adherence to the neotraditional pattern. Conclusion: A neotraditional dietary pattern, comprising local produce, should be encouraged as a possible childhood obesity prevention strategy in Samoa

Consensus-building during the Becoming Breastfeeding Friendly (BBF) initiative in Samoa: A qualitative content analysis.

The Becoming Breastfeeding Friendly (BBF) initiative provides countries with an evidence-based toolbox to improve the national breastfeeding environment by assessing and developing a plan to effectively scale up well-coordinated national policies and programs. BBF is carried out by a multi-institutional, intersectoral committee of experts, convening across five committee meetings designed to produce policy recommendations that can be implemented in the country's context. Samoa successfully completed the BBF initiative in 2018, resulting in the institution of breastfeeding policy in hospitals and the establishment of lactation rooms within government ministries. An important step in informing the success of future breastfeeding scale-up initiatives is understanding how consensus is built. This study aimed to investigate how the BBF Samoa committee built consensus. We conducted a content analysis of audio recordings of three BBF Samoa meetings (meetings 1, 2 and 4), meeting minutes, and meeting notes using an a priori operational consensus-building framework. We used a combination of deductive and inductive approaches to: a) evaluate the data against existing, a priori criteria for consensus-building and b) identify emergent ways in which the BBF Samoa committee may have achieved consensus. We identified 6 themes, 2 meta-subthemes, and 16 subthemes. The 6 themes, largely defined by the a priori framework, represented key components of successful consensus-building. The 2 meta-subthemes described two overarching methods of consensus-building: "process-led" (i.e., inherent to the BBF process itself) and "organic" (unique/specific to the committee). Lastly, the 16 subthemes described more specific ways that the committee reached consensus. The detailed manualization of the BBF process, its reliance on data, and its transparent and engaged committee process were key for reaching consensus on BBF scores and recommendations in Samoa. Our study contributes to the understanding of how effective breastfeeding policy recommendations are made, using a methodology that can be applied beyond the topic of breastfeeding

Comparability of The Netherlands Physical Activity Questionnaire with Accelerometer-Measured Physical Activity in Samoan Children: A Retrospective Analysis of Ola Tuputupua’e Data

Accurate measurement of physical activity is critical to understand its role in cardiometabolic health and obesity development in children and to monitor trends in behavior and evaluate interventions. An ongoing mixed-longitudinal study of child growth and development in Samoa is collecting physical activity data with both accelerometers and the Netherlands Physical Activity Questionnaire (NPAQ). The aims of our analyses were to (1) describe the response frequency and correlations of individual questions in the NPAQ, (2) develop modified NPAQ scores with selected questions and (3) examine the concordance of modified NPAQ scores with accelerometer outcomes among children aged 2–4 years. We developed two modified NPAQ scores with combinations of questions and assessed concordance of the modified scores with accelerometer data using estimated marginal means adjusted for monitor wear time. Although the evenly distributed tertiles of the modified 15-point NPAQ score showed promising trends of increasing minutes of accelerometer-assessed high-intensity physical activity with increasing tertile, the estimated marginal means were imprecise with high variance, demonstrating that NPAQ score could not accurately assess physical activity levels of preschool-aged children in Samoa. Considering that questionnaires are often considered more cost-effective tools for physical activity measurement than accelerometry, further research is necessary to develop a culturally and age-appropriate physical activity questionnaire in this population

Prevalence of malnutrition among Samoan children aged 5 to 11 years in 2019–2020

Background Globally, rapid economic development, urbanisation, and nutrition transitions have led to rising levels of malnutrition in all forms. Aim The study objective was to document the prevalence of overweight/obesity, underweight, stunting, and anaemia among Samoan children in 2019–2020. Subjects and methods Children from the Ola Tuputupua’e “Growing Up” in Samoa study at ages 5–11 years with complete physical assessments were included. Overweight/obesity, underweight, and stunting were classified using World Health Organisation Z-scores for body mass index-for-age (BMIZ> +1), weight-for-age (WAZ< −2SD), and height-for-age (HAZ< −2SD), respectively. Anaemia was defined as haemoglobin concentration <11.5 g/dL. Prevalence was compared by child age, sex, and census region of residence (representing urbanicity and exposure to nutrition transition) using Wilcoxon two-sample, Chi-square, or Fisher’s exact tests. Results The prevalence of overweight/obesity, underweight, stunting, and anaemia was 36.2%, 0.5%, 1.6%, and 31.6%, respectively. Overweight/obesity in children was positively associated with age and highly prevalent in periurban and urban regions. While children living in the rural region with the lowest exposure to nutrition transition had the highest prevalence of mild-to-moderate stunting, anaemia prevalence was lower compared to those in the urban region. No sex differences in malnutrition were observed. Conclusion Moderate-to-high levels of overweight/obesity and anaemia call for comprehensive intervention strategies
