RESUMO

Aim: To explore the perspectives and experiences of healthcare practitioners in providing nutrition care to people with cancer in New Zealand. Methods: Semi-structured interviews were conducted with 16 New Zealand healthcare professionals (HCPs) practicing in specialist secondary and tertiary cancer care (both public and private) who had previously completed an online survey about nutrition in cancer care. Interviews were recorded and transcribed verbatim, and thematic analysis was undertaken. Results: Participants identified nutrition as important in cancer care, from diagnosis to survivorship, in order to maximise recovery and ongoing health. While participants reported that the best person to provide high-quality individualised nutrition care is a dietitian, other HCPs also have a role in nutrition care. Limited nutrition care is currently available, especially for those in rural areas, which impacts health and equity in cancer care. Participants identified a need for increased dietitian capacity in the workforce as well as a need for nutrition resources that were accessible and appropriate. Conclusion: The perspective of participants was that more must be done to provide nutrition care as part of cancer care in New Zealand to improve health and wellbeing among people with cancer.

RESUMO

(1) Background: The best method to assess discretionary salt intake in population surveys has not been established. (2) Methods: This secondary analysis compared three different methods of measuring sodium intake from discretionary salt in a convenience sample of 109 adults in New Zealand. Participants replaced their household salt with lithium-tagged salt provided by researchers over eight days. Baseline 24 h urine was collected, and two further 24 h urine and 24 h dietary recalls were collected between days six and eight. Discretionary salt was estimated from the lithium-tagged salt, focused questions in the 24 h dietary recall, and the 'subtraction method' (a combination of 24 h urine and 24 h dietary recall measures). (3) Results: Around one-third of estimates from the 'subtraction method' were negative and therefore unrealistic. The mean difference between 24 h dietary recall and lithium-tagged salt estimates for sodium from discretionary salt mean were 457 mg sodium/day and 65 mg/day for mean and median, respectively. (4) Conclusions: It is possible to obtain a reasonable estimate of discretionary salt intake from careful questioning regarding salt used in cooking, in recipes, and at the table during a 24 h recall process to inform population salt reduction strategies.

RESUMO

BACKGROUND: The use of iodized salt is a key strategy to increase iodine intake worldwide. In many countries, including New Zealand, females of reproductive age are still at risk of being mildly iodine deficient. OBJECTIVE: This study aimed to determine the level of iodization of salt needed to ensure that females aged 18 to 40 y have an adequate intake of iodine in 2 scenarios: current discretionary salt intake and reduced discretionary salt intake. METHOD: Data from nonpregnant, nonlactating females aged 18 to 40 y (n = 795) who took part in the 2008/09 New Zealand Adult Nutrition Survey and completed a 24-h dietary recall were used. Iodine intake was determined from all foods except bread and discretionary salt, which are fortified with iodine. Iodine from bread and salt was estimated at different levels of salt iodization, starting at 25 mg iodine/kg salt and increasing incrementally by 5 mg/kg, and added to calculate total iodine intake. The simulation concluded when the appropriate iodine content in salt was found using the estimated average requirement (EAR) cut-point method. RESULTS: In the 2 scenarios, current discretionary salt intake (i.e., 400 mg/d) and reduced discretionary salt intake (i.e., 304 mg/d), the iodine concentration of salt is required to be 55 mg/kg and 70 mg/kg for no more than 2% of females to have an iodine intake below the EAR of 100 µg of iodine/d, respectively. In both scenarios and at all levels of iodine concentration, no one was above the upper level of intake of iodine of 1100 µg/d. CONCLUSIONS: This study found that females of reproductive age need to consume iodized salt at the higher end of the legislated range of 25 to 65 mg/kg. If strategies to reduce sodium intake were adopted, the range would need to increase, or iodized salt would need to be included in a wider range of staple foods.

RESUMO

OBJECTIVE: To examine the trajectories of BMI in Indonesian adults from 1993 to 2014, investigating different patterns by sex and birth cohort. DESIGN: Longitudinal study: secondary data analysis of the Indonesian Family Life Survey, a large-scale population-based longitudinal study, had their height and weight measured up to five times throughout the 21-year study period (1993-2014). The change in BMI across time was estimated using group-based trajectory models, then differences by sex and birth cohort were investigated using random effect (mixed) models. SETTING: Thirteen out of twenty-seven provinces in Indonesia. PARTICIPANTS: Indonesian adults aged 19 years and older (n 42 537) were included in the analysis. RESULTS: Mean BMI in adults increased between 1993 (21·4 kg/m2) and 2014 (23·5 kg/m2). The group-based trajectory model found three distinct groups with mean BMI increasing more rapidly in the most recent time periods. The first group (56·7 % of participants) had a mean BMI entirely within the normal weight range; the second group (34·7 %) started in the normal weight category and were obese, on average by the end of the study period; and the third group (8·6 %) were always in the obese category, on average. The shape of these three trajectories differed by gender (P < 0·001) and birth cohort (P < 0·001). CONCLUSIONS: The mean BMI among Indonesian adults has increased between 1993 and 2014, driven by those in the most recent birth cohorts. Our findings support the urgent need for targeted overweight and obesity prevention and intervention programmes in Indonesia.

RESUMO

BACKGROUND: Even modest reductions in blood pressure (BP) can have an important impact on population-level morbidity and mortality from cardiovascular disease. There are 2 promising approaches: the SaltSwitch smartphone app, which enables users to scan the bar code of a packaged food using their smartphone camera and receive an immediate, interpretive traffic light nutrition label on-screen alongside a list of healthier, lower-salt options in the same food category; and reduced-sodium salts (RSSs), which are an alternative to regular table salt that are lower in sodium and higher in potassium but have a similar mouthfeel, taste, and flavor. OBJECTIVE: Our aim was to determine whether a 12-week intervention with a sodium-reduction package comprising the SaltSwitch smartphone app and an RSS could reduce urinary sodium excretion in adults with high BP. METHODS: A 2-arm parallel randomized controlled trial was conducted in New Zealand (target n=326). Following a 2-week baseline period, adults who owned a smartphone and had high BP (≥140/85 mm Hg) were randomized in a 1:1 ratio to the intervention (SaltSwitch smartphone app + RSS) or control (generic heart-healthy eating information from The Heart Foundation of New Zealand). The primary outcome was 24-hour urinary sodium excretion at 12 weeks estimated via spot urine. Secondary outcomes were urinary potassium excretion, BP, sodium content of food purchases, and intervention use and acceptability. Intervention effects were assessed blinded using intention-to-treat analyses with generalized linear regression adjusting for baseline outcome measures, age, and ethnicity. RESULTS: A total of 168 adults were randomized (n=84, 50% per group) between June 2019 and February 2020. Challenges associated with the COVID-19 pandemic and smartphone technology detrimentally affected recruitment. The adjusted mean difference between groups was 547 (95% CI -331 to 1424) mg for estimated 24-hour urinary sodium excretion, 132 (95% CI -1083 to 1347) mg for urinary potassium excretion, -0.66 (95% CI -3.48 to 2.16) mm Hg for systolic BP, and 73 (95% CI -21 to 168) mg per 100 g for the sodium content of food purchases. Most intervention participants reported using the SaltSwitch app (48/64, 75%) and RSS (60/64, 94%). SaltSwitch was used on 6 shopping occasions, and approximately 1/2 tsp per week of RSS was consumed per household during the intervention. CONCLUSIONS: In this randomized controlled trial of a salt-reduction package, we found no evidence that dietary sodium intake was reduced in adults with high BP. These negative findings may be owing to lower-than-anticipated engagement with the trial intervention package. However, implementation and COVID-19-related challenges meant that the trial was underpowered, and it is possible that a real effect may have been missed.

RESUMO

ISSUE ADDRESSED: The objective was to identify whether National Sporting Organisations (NSOs) have policy documentation on healthy behaviours (smokefree, sun-protection, healthy food/beverages and alcohol) and, for organisations with such documentation, whether this was in-line with current scientific evidence of past best practice in cancer prevention. METHODS: This cross-sectional policy analysis study was performed September to December 2018 in Aotearoa/New Zealand. A content analysis was undertaken using NSO policy documents matched against a framework of key indicators for best practice within health behaviours of interest. Data analysis of the policy process was undertaken through key informant telephone interviews with NSO staff using semi-structured qualitative interviews. RESULTS: Of 96 NSOs, nearly half (49%) mentioned smokefree at least once in one of their policy documents, and 47% had an alcohol policy, although in both instances the policies lacked comprehensiveness. Two NSOs had a reasonably comprehensive sun protection policy. Seventeen had at least one specific nutrition policy/guideline. The contents of the latter were primarily related to short-term athletic performance rather than non-communicable disease prevention, specifically promoting hydration during sports participation, and food and nutrition to support sporting performance. Two NSOs had policies relating to the promotion of healthy food/nutrition more widely. For some NSOs, the lack of health-related policies was not a conscious choice but just not considered previously. Other NSOs reported they lacked resources or had other priorities. CONCLUSIONS: Although this study clearly demonstrates that many NSOs lack adequate health-related policies, this is not necessarily a conscious choice, but the result of a lack of resources, other priorities, or just that they had not considered developing policies in these areas. A number expressed support for these types of policies although it was apparent that some, particularly smaller NSOs, would require assistance in policy template development. It seems probable that the development of health-related policies will only occur if partner agencies become involved.

RESUMO

BACKGROUND: Gender equality, zero hunger and healthy lives and well-being for all, are three of the Sustainable Development Goals (SDGs) that underpin Fiji's National Development Plan. Work towards each of these goals contributes to the reduction of non-communicable diseases (NCDs). There are gender differences in NCD burden in Fiji. It is, however, unclear whether a gender lens could be more effectively included in nutrition and health-related policies. METHODS: This study consisted of three components: (i) a policy content analysis of gender inclusion in nutrition and health-related policies (n = 11); (ii) policy analysis using the WHO Gender Analysis tool to identify opportunities for strengthening future policy; and (iii) informant interviews (n = 18), to understand perceptions of the prospects for gender considerations in future policies. RESULTS: Gender equality was a goal in seven policies (64%); however, most focused on women of reproductive age. One of the policies was ranked as gender responsive. Main themes from key informant interviews were: 1) a needs-based approach for the focus on specific population groups in policies; 2) gender-related roles and responsibilities around nutrition and health; 3) what is considered "equitable" when it comes to gender, nutrition, and health; 4) current considerations of gender in policies and ideas for further gender inclusion; and 5) barriers and enablers to the inclusion of gender considerations in policies. Informants acknowledged gender differences in the burden of nutrition-related NCDs, yet most did not identify a need for stronger inclusion of gender considerations within policies. CONCLUSIONS: There is considerable scope for greater inclusion of gender in nutrition and health-related policies in Fiji. This could be done by: 1) framing gender considerations in ways that are actionable and inclusive of a range of gender identities; 2) undertaking advocacy through actor networks to highlight the need for gender-responsive nutrition and health-related policies for key stakeholder groups; 3) ensuring that data collected to monitor policy implementation is disaggregated by sex and genders; and 4) promoting equitable participation in nutrition related issues in communities and governance processes. Action on these four areas are likely critical enablers to more gender equitable NCD reduction in Fiji.

RESUMO

OBJECTIVE: To investigate perceptions of iTaukei Fijian women and men around diet and the ability to consume a healthy diet. DESIGN: Six focus groups were conducted with women and men separately. Six to ten women and men participated in each group. Discussions were recorded, transcribed, translated and thematically analysed. Themes were mapped to an intersectionality framework to aid interpretation. SETTING: Four villages in Viti Levu, Fiji. PARTICIPANTS: Twenty-two women and twenty-four men. RESULTS: Seven overarching themes were identified, including generational changes in food behaviour, strong-gendered beliefs around food and food provision, cultural and religious obligations around food, the impact of environmental change on the ability to consume a healthy diet, perceptions of the importance of food, food preferences and knowledge. Participants across focus groups identified that it was the 'duty' of women to prepare food for their families. However, some women reflected on this responsibility being unbalanced with many women now in the formal workforce. Changes between generations in food preferences and practices were highlighted, with a perception that previous generations were healthier. Power dynamics and external factors, such as environmental changes, were identified by women and men as crucial influences on their ability to eat a healthy diet. CONCLUSION: Embedded traditional perceptions of gendered roles related to nutrition were misaligned with other societal and environmental changes. Given factors other than gender, such as broader power dynamics and environmental factors were identified as influencing diet, viewing nutrition-related issues through an intersectional lens is important to inform equitable food policy in Fiji.

RESUMO

The World Hypertension League Science of Salt health outcomes review series highlights high-quality publications relating to salt intake and health outcomes. This review uses a standardised method, outlined in previous reviews and based on methods developed by WHO, to identify and critically appraise published articles on dietary salt intake and health outcomes. We identified 41 articles published between September 2019 to December 2020. Amongst these, two studies met the pre-specified methodological quality criteria for critical appraisal. They were prospective cohort studies and examined physical performance and composite renal outcomes as health outcomes. Both found an association between increased/higher sodium intake and poorer health outcomes. Few studies meet criteria for high-quality methods. This review adds further evidence that dietary salt reduction has health benefits and strengthens evidence relating to health outcomes other than blood pressure and cardiovascular disease. We observe that most studies on dietary sodium do not have adequate methodology to reliably assess sodium intake and its association with health outcomes.

RESUMO

AIM: This research sought to identify and understand what nutrition-related information and support is available to people undergoing cancer treatment. We also sought the views on nutrition for cancer among providers of cancer care/support, and barriers/enablers to the provision of nutrition information/support. METHOD: Data were collected using online surveys with New Zealand-based healthcare practitioners and support workers. Descriptive analysis was undertaken. Open-ended questions were analysed for explanatory content to help us interpret and understand the results. RESULTS: Most healthcare practitioners and support workers viewed nutrition as at least moderately important (for cancer recovery, patient wellbeing and preventing cancer recurrence) and believed nutrition information/support should be provided to cancer patients. However, nutrition information and support were not widely available through oncology practices and cancer support services. The main barriers to the provision of nutrition information and support (including access to dietitian appointments) were insufficient funding and lack of time/staff capacity. Additional barriers included a lack of access to evidence-based information and dietary expertise. CONCLUSION: Nutrition information and support needs to be more widely available and standardised across New Zealand's oncology services. Ideally this would include general introductory information about nutrition (eg, World Cancer Research Fund recommendations) from all healthcare practitioners and more detailed tailored advice (and ongoing support where needed) from dietitians.
