The Singaporean foodscape - Convenience, choice, entertainment, and sociality for young workers.

Singapore is famous for its diverse, affordable, and exciting foodscape. This paper focuses on understanding the multifaceted role that the Singaporean food environment plays in working young adults' lives, and how young adults interact with this environment to make food choices. Using a focused ethnographic approach, including 33 semi-structured interviews and participant-observation, we explore the ways in which busy working young adults interact with the foodscape. The food environment provides young adults, who eat out frequently, with highly accessible food options that cater to their budgets and palates. They often dine at hawker centres and similar food establishments with colleagues, friends and family. These establishments offer accessible, affordable, and appealing food. Overall, the foodscape provides a source of popular entertainment through the exploration of diverse cuisines and novel shared social experiences. Young adults are heavy users of social media to maintain social networks and to explore the food environment. Capitalizing on this, food marketing on social media targets this group with the promotion of food-related experiences. While it may not always promote healthy eating, the Singaporean foodscape offers convenience, choice, entertainment, and sociality. In the process, it facilitates the formation of cultural and national identity and the protection of mental well-being through the maintenance and development of relationships, and a sense of belonging.

Regulating the marketing of foods for infants and young children: Lessons from assessment of gaps in monitoring and enforcement in Thailand.

Breast milk substitute (BMS) marketing harms breastfeeding and public health. To control BMS marketing, the Member States of the World Health Organization is called upon to adopt all provisions of the International Code of Marketing of Breastmilk Substitutes (the Code) into national law. In 2017, Thailand adopted many provisions of the Code through the Control of Marketing Promotion of Infant and Young Child Food Act B.E. 2560 (the Act), including the establishment of a compliance monitoring system and enforcement mechanisms. Nevertheless, recent research showed widespread violations. This study aims to assess gaps in the monitoring system and the Act's enforcement in its first three years of operation. This qualitative research study employed in-depth interviews between April and June 2020 with 34 key informants (KIs) from the Thai government, academia and civil society organisations. KIs identified gaps in six areas that could be mitigated to increase compliance with the Act. These gaps are unclear provisions on coverage of the Act; communications with retailers and the public; lack of strong direction and processes; inadequate budget allocations; skilled and confident human resources; and external factors which facilitate BMS marketing. Recommendations may be relevant for other countries and include revising and clarifying the Act, developing targeted communication strategies; providing clear monitoring direction including through setting key performance indicators related to the Act; and providing sufficient budget and training for authorised and support officers. Strengthening the health system and workplace support for breastfeeding and social marketing would also help address wider structural factors.

Regulation of baby food marketing in Thailand: a NetCode analysis.

OBJECTIVE: To report on the prevalence of different types of breast-milk substitutes (BMS) marketing and the compliance of such marketing with the 'Control of Marketing of Infant and Young Child Food Act 2017' (The Act) and the 'International Code of Marketing of Breast-milk Substitutes (WHO Code)' in Thailand. DESIGN: Cross-sectional quantitative study, guided by the WHO/UNICEF NetCode Periodic Assessment Protocol. SETTING: Health facilities and retail outlets in Bangkok, Thai media. PARTICIPANTS: Mothers of 0-2-year-old children, health professionals, promotions at retail outlets and health facilities, product labels, marketing on television and the internet. RESULTS: Marketing to mothers was highly prevalent, mostly from electronic or digital media, while BMS companies provided items to health professionals to distribute to mothers. Promotional materials in health facilities displayed company brands or logos. At retail outlets, most promotions were price-related. Approximately two-fifths of labels contained nutrition or health claims. Television marketing was growing-up-milk (GUM) advertisements, while internet promotions were varied from price-related materials to product reviews. Most instances of non-compliant BMS marketing with the Act were advertisements to mothers, and most were infant formula. Most non-compliant BMS marketing with the WHO Code was mainly concerned GUM, which are not covered by the Act and appeared in the media. CONCLUSIONS: BMS marketing does not fully comply with the Act or the WHO Code. The Thai government should conduct regular monitoring and enforcement activities, educate health professionals, and strengthen the Act's provisions on the media and GUM to fully align with the WHO Code.

COVID-19 and mental health in Australia - a scoping review.

BACKGROUND: The COVID-19 outbreak has spread to almost every country around the world and caused more than 3 million deaths. The pandemic has triggered enormous disruption in people's daily lives with profound impacts globally. This has also been the case in Australia, despite the country's comparative low mortality and physical morbidity due to the virus. This scoping review aims to provide a broad summary of the research activity focused on mental health during the first 10 months of the pandemic in Australia. RESULTS: A search of the Australian literature was conducted between August-November 2020 to capture published scientific papers, online reports and pre-prints, as well as gaps in research activities. The search identified 228 unique records in total. Twelve general population and 30 subpopulation group studies were included in the review. CONCLUSIONS: Few studies were able to confidently report changes in mental health driven by the COVID-19 context (at the population or sub-group level) due to a lack of pre-COVID comparative data and non-representative sampling. Never-the-less, in aggregate, the findings show an increase in poor mental health over the early period of 2020. Results suggest that young people, those with pre-existing mental health conditions, and the financially disadvantaged, experienced greater declines in mental health. The need for rapid research appears to have left some groups under-researched (e.g. Culturally and Linguistically Diverse populations and Indigenous peoples were not studied), and some research methods under-employed (e.g. there was a lack of qualitative and mixed-methods studies). There is a need for further reviews as the follow-up results of longitudinal studies emerge and understandings of the impact of the pandemic are refined.

Social networking sites: a new source of child feeding information for parents in Thailand.

Social networking sites (SNSs) provide opportunities for health and nutrition communication. Data are lacking on whether these SNSs influence Thai parent's food provisioning to young children. In the current study, we examined the prevalence and characteristics of Thai parents who reported participating in child food and nutrition-SNSs and investigated the association between participation in these sites and parents' perceptions and feeding practices. A sample of 379 Thai parents completed a survey about the use of child food and nutrition-SNSs, and feeding practices and child eating behavior. Around 70% of participants, especially female millennials with their first child, have participated in SNSs that provide information about children's diets. High engagement was more common among younger and less educated participants, as well as rural dwellers and those with abnormal body mass index. Among these SNSs' participants, those with higher engagement had higher levels of trust in the nutritional information shared on SNSs. Further analyses showed that parents who have joined these sites had positive associations with not only providing children with more fresh fruits and vegetable but also more processed meats. Further investigations are needed to explore the information these SNSs provided and what influences they have on parents' perceptions around feeding children.

Developing a conceptual framework for implementation science to evaluate a nutrition intervention scaled-up in a real-world setting.

OBJECTIVE: The aim of this paper is to identify and develop a comprehensive conceptual framework using implementation science that can be applied to assess a nutrition intervention in a real-world setting. DESIGN: We conducted a narrative review using electronic databases and a manual search to identify implementation science frameworks, models and theories published in peer-reviewed journals. We performed a qualitative thematic analysis of these publications to generate a framework that could be applied to nutrition implementation science. RESULTS: Based on this review, we developed a comprehensive framework which we have conceptualised as an implementation science process that describes the transition from the use of scientific evidence through to scaling-up with the aim of making an intervention sustainable. The framework consisted of three domains: Domain i - efficacy to effectiveness trials, Domain ii - scaling-up and Domain iii - sustainability. These three domains encompass five components: identifying an 'effective' intervention; scaling-up and implementation fidelity; course corrections during implementation; promoting sustainability of interventions and consideration of a comprehensive methodological paradigm to identify 'effective' interventions and to assess the process and outcome indicators of implementation. The framework was successfully applied to a nutrition implementation program in Bangladesh. CONCLUSIONS: Our conceptual framework built from an implantation science perspective offers a comprehensive approach supported by a foundational and holistic understanding of its key components. This framework provides guidance for implementation researchers, policy-makers and programme managers to identify and review an effective intervention, to scale it up and to sustain it over time.

Use of concurrent evaluation to improve implementation of a home fortification programme in Bangladesh: a methodological innovation.

OBJECTIVE: This paper focuses on the use of 'concurrent evaluation' to evaluate a nationally scaled-up programme in Bangladesh that was implemented by BRAC (an international development organisation) using Shasthya Shebika (SS) - volunteer community health workers - to promote home fortification with micronutrient powders (MNP) for children under-five. DESIGN: We developed a programme impact pathway to conceptualise the implementation and evaluation strategy and developed a strategic partnership among the key programme stakeholders for better use of evaluation evidence. We developed a multi-method concurrent evaluation strategy to provide insights into the BRAC programme and created provision for course correction to the implementation plan while it was in operation. SETTING: One hundred sixty-four sub-districts and six urban slums in Bangladesh. PARTICIPANTS: Caregivers of children 6-59 months, SS and BRAC's staff members. RESULTS: The evaluation identified low awareness about home fortification among caregivers, inadequate supply and frequent MNP stockouts, and inadequate skills of BRAC's SS to promote MNP at the community level as hindrances to the achievement of programme goals. The partners regularly discussed evaluation results during and after implementation activities to assess progress in programme coverage and any needs for modification. BRAC initiated a series of corrections to the original implementation plan to address these challenges, which improved the design of the MNP programme; this resulted in enhanced programme outcomes. CONCLUSIONS: Concurrent evaluation is an innovative approach to evaluate complex real-world programmes. Here it was utilised in implementing a large-scale nutrition programme to measure implementation process and effectiveness.

Factors associated with home visits by volunteer community health workers to implement a home-fortification intervention in Bangladesh: a multilevel analysis.

OBJECTIVE: BRAC, an international development organization based in Bangladesh, engages community health workers called Shasthya Shebikas (SS) to implement home fortification of foods with micronutrient powders (MNP). We identified factors associated with home visits by SS, at different levels of the BRAC programme-delivery hierarchy, to implement home-fortification interventions. DESIGN: We conducted a cross-sectional survey, semi-structured interviews, and collected programme-related data from sub-districts included in the caregiver survey of BRAC's home-fortification programme and performed multilevel logistic regression modelling to investigate factors associated with home visits by SS. SETTINGS: Sixty-eight sub-districts in Bangladesh. PARTICIPANTS: Caregivers of children aged 6-59 months (n 1408) and BRAC's SS (n 201). RESULTS: Households with older children (0·55; 0·42, 0·72; P < 0·001) and located >300 m from the SS's house (0·67; 0·50, 0·89; P = 0·006) were less likely to have been visited by the SS, whereas those with caregivers who had ≥5 years of schooling (1·53; 1·10, 2·12; P = 0·011) were more likely to have been visited by the SS (adjusted OR; 95 % CI). Households in the catchment area of older SS aged >50 years (0·44; 0·21, 0·90; P = 0·025) were less likely to have been visited by the SS, whereas those with SS who received incentives of >800 BDT (3·00; 1·58, 5·58; P = 0·001) were more likely to have been visited by the SS (adjusted OR; 95 % CI). CONCLUSIONS: The number of home visits is a function of the characteristics of SS, factors that characterize the households they serve and characteristics of their organizational context, particularly to implement home fortification of foods with MNP.

Role of home visits by volunteer community health workers: to improve the coverage of micronutrient powders in rural Bangladesh.

OBJECTIVE: We assessed the role of home visits by Shasthya Shebika (SS) - female volunteer community health workers (CHWs) - in improving the distribution of micronutrient powder (MNP), and explored the independent effects of caregiver-provider interaction on coverage variables. DESIGN: We used data from three cross-sectional surveys undertaken at baseline (n 1927), midline (n 1924) and endline (n 1540) as part of an evaluation of a home fortification programme. We defined an exposure group as one that had at least one SS visit to the caregiver's household in the 12 months preceding the survey considering three outcome variables - message (ever heard), contact (ever used) and effective coverage (regular used) of MNP. We performed multiple logistic regressions to explore the determinants of coverage, employed an 'interaction term' and calculated an odds ratio (OR) to assess the modifying effect of SS's home visits on coverage. SETTINGS: Sixty-eight sub-districts from ten districts of Bangladesh. PARTICIPANTS: Children aged 6-59 months and their caregivers. RESULTS: A home visit from an SS positively impacts message coverage at both midline (ratio of OR 1·70; 95 % CI 1·25, 2·32; P < 0·01) and endline (ratio of OR 3·58; 95 % CI 2·22, 5·78; P < 0·001), and contact coverage both at midline (ratio of OR 1·48; 95 % CI 1·06, 2·07; P = 0·021) and endline (ratio of OR 1·74; 95 % CI 1·23, 2·47; P = 0·002). There was no significant effect of a SS's home visit on effective coverage. CONCLUSIONS: The households visited by BRAC's volunteer CHWs have better message and contact coverage among the children aged 6-59 months.

Pathways to care: a case study of traffic injury in Vietnam.

BACKGROUND: Traffic injuries place a significant burden on mortality, morbidity and health services worldwide. Qualitative factors are important determinants of health but they are often ignored in the study of injury and corresponding development of prehospital Emergency Medical Services (EMS), especially in developing country settings. Here we report our research on sociocultural factors shaping pathways to hospital care for those injured on the roads and streets of Vietnam. METHODS: Qualitative fieldwork on pathways to emergency care of traffic injury was carried out from March to August 2016 in four hospitals in Vietnam, two in Ho Chi Minh City and two in Hanoi. Forty-eight traffic injured patients and their families were interviewed at length using a semi-structured topic guide regarding their journey to the hospital, help received, personal beliefs and other matters that they thought important. Transcribed interviews were analysed thematically guided by the three-delay model of emergency care. RESULTS: Seeking care was the first delay and reflected concerns over money and possessions. The family was central for transporting and caring for the patient but their late arrival prolonged time spent at the scene. Reaching care was the second delay and detours to inappropriate primary care services had postponed the eventual trip to the hospital. Ambulance services were misunderstood and believed to be suboptimal, making taxis the preferred form of transport. Receiving care at the hospital was the third delay and both patients and families distrusted service quality. Request to transfer to other hospitals often created more conflict. Overall, sociocultural beliefs of groups of people were very influential. CONCLUSIONS: Analysis using the three-delay model for road traffic injury in Vietnam has revealed important barriers to emergency care. Hospital care needs to improve to enhance patient experiences and trust. Socioculture affects each of the three delays and needs to inform thinking of future developments of the EMS system, especially for countries with limited resources.

Child feeding practices and concerns: Thematic content analysis of Thai virtual communities.

Parents' child feeding practices are influenced not only by family but also by a broader circle of networks, including online groups. Peer-to-peer platforms such as Facebook groups facilitate a learning environment and may influence the transmission of user-generated content into practice. These digital data not only benefit participants but also offer new opportunities for researchers to study related phenomena. Therefore, this study employs thematic content analysis to investigate peer-exchanging discourse conveyed in Facebook peer-support groups in children's diets in Thailand. To identify the area of interest, we classified and quantified the initial posts and investigated the relationship between initial posts' contents and community engagement. Thematic analysis was used to qualitatively describe the peer-exchanging content that responded to the initial posts. Of the five approved Facebook groups, 200 initial posts with their 1964 comments were extracted anonymously. Results revealed that Facebook groups devoted to diets for children have become a platform for Thai parents to seek informational and emotional support. The top-ranked initial posts were related to requesting knowledge and skills about age-appropriate food and meal preparation. Parents have also expressed anxiety about feeding and tension related to food fussiness which created the need for emotional support. Age-appropriate feeding, homemade baby foods, concerns about food seasonings and food allergy awareness were observable within online groups. However, a shift from traditional child feeding practices to new ideas created cultural gaps which lead to arguments in some families. Understanding these views would help guide to address parental concerns better.

Implementation of the World's largest measles-rubella mass vaccination campaign in Bangladesh: a process evaluation.

BACKGROUND: Gavi, the Vaccine Alliance, supported a mass vaccination Measles-Rubella Campaign (MRC) in Bangladesh during January-February 2014. METHODS: We conducted a mixed-method process evaluation to understand the successes and challenges in implementation of the MRC. We reviewed documents for the MRC and the immunization programme in Bangladesh; observed meetings, vaccination sessions, and health facilities; and conducted 58 key informant interviews, 574 exit interviews with caregivers and 156 brief surveys with stakeholders involved in immunization. Our theory of Change for vaccination delivery guided our assessment of ideal implementation milestones and indicators to compare with the actual implementation processes. RESULTS: We identified challenges relating to country-wide political unrest, administrative and budgetary delays, shortage of transportation, problems in registration of target populations, and fears about safety of the vaccine. Despite these issues, a number of elements contributed to the successful launch of the MRC. These included: the comprehensive design of the campaign; strong partnerships between immunization authorities in the government system, Alliance partners, and civil society actors; and motivated and skilled health workers at different levels of the health system. CONCLUSIONS: The successful implementation of the MRC in spite of numerous contextual and operational challenges demonstrated the adaptive capacity of the national immunization programme and its partners that has positive implications for future introductions of Gavi-supported vaccines.

'Telling our story... Creating our own history': caregivers' reasons for participating in an Australian longitudinal study of Indigenous children.

BACKGROUND: Improving the wellbeing of Indigenous populations is an international priority. Robust research conducted with Aboriginal and Torres Strait Islander peoples is key to developing programs and policies to improve health and wellbeing. This paper aims to quantify the extent of participation in a national longitudinal study of Aboriginal and Torres Strait Islander (Indigenous Australian) children, and to understand the reasons why caregivers participate in the study. METHODS: This mixed methods study uses data from Wave 6 of Footprints in Time, the Longitudinal Study of Indigenous Children. We conducted descriptive analysis of quantitative variables to characterise the sample and retention rates. We applied conventional content analysis to 160 caregivers' open-ended responses to the question, 'Why do you stay in the study?', identifying themes and overarching meta-themes. RESULTS: The study has maintained a high retention rate, with 70.4% (n = 1239/1671) of the baseline sample participating in the study's 6th wave. We identified seven themes related to why participants stay in the study: telling our story, community benefit, satisfaction, tracking Study Child's progress, study processes, receiving study gifts, and valuing what the study stands for. These related to two meta-themes: reciprocity, and trust and connection. Caregivers reported that participation was associated with benefits for their family and community as well as for the study. They identified specific features of the Footprints in Time study design that built and maintained trust and connection between participants and the study. CONCLUSIONS: Our findings support the assertion that Aboriginal and Torres Strait Islander people want to be involved in research when it is done 'the right way'. Footprints in Time has successfully recruited and retained the current-largest cohort of Aboriginal and Torres Strait Islander children in Australia through the use of participatory research methodologies, suggesting effective study implementation and processes. Participants indicated ongoing commitment to the study resulting from perceptions of reciprocity and development of trust in the study. Footprints in Time can serve as a successful model of Aboriginal and Torres Strait Islander health research, to promote good research practice and provides lessons for research with other Indigenous populations.

Social determinants of household food expenditure in Australia: the role of education, income, geography and time.

OBJECTIVE: To examine socio-economic status (SES) and time-related factors associated with less healthy food purchases in Australia. DESIGN: Data were from the 2009/10 Household Expenditure Survey (HES) conducted by the Australian Bureau of Statistics. Regression analysis was used to examine the associations between the proportion of the household food budget spent on various food types (processed and unprocessed foods, foods purchased from takeaways and restaurants) and SES and time constraint variables. SETTING: Australia, 2009-2010. SUBJECTS: Nationally representative sample of Australian households. RESULTS: Household income seems to be the most important correlate with food expenditure patterns once other SES indicators are controlled for. Time constraints appear to explain some, but not all, of the adjusted SES gradients in food expenditure. Comparing home food consumption categories (processed and unprocessed foods) with foods purchased away from home (takeaway and restaurant foods) shows that wealthier, more highly educated and least disadvantaged households spend relatively less of their total food budget on processed and unprocessed foods prepared at home and more on foods purchased away from home at restaurants. CONCLUSIONS: Simple SES gradients in dietary behaviour are influenced by correlations between different SES indicators and between SES and time constraints. Examining these factors separately obscures some of the possible causal effects of disadvantage on healthy eating. When formulating policy responses to unhealthy diets, policy makers should consider alternative sources of disadvantage, including time pressure.

Time and participation in workplace health promotion: Australian qualitative study.

Workplaces are considered promising settings for protecting and promoting the health and wellbeing of employees. To date, few workplaces, particularly small and medium sized enterprises (SME), or their workers, have adopted Workplace Health Promotion (WHP), raising questions as to why. We conducted interviews in 10 SME in the Australian Capital Territory (ACT) asking managers and workers to reflect on the reasons for their participation (or not) in WHP activities. We qualitatively explored factors that managers consider important when deciding whether to offer WHP and compared these to worker considerations regarding participation. Both workers and managers identified time constraints as a major barrier for participation in WHP activities. If WHP was implemented, time constraints arose mainly from: difficulties scheduling and synchronising activities to include most staff, even then casual staff were mostly excluded; and the duration of time required by employees to participate in the offered activities, and whether this was in paid (work) or unpaid (worker) time. Workers struggled to participate in WHP in their scheduled breaks and were reluctant to use time outside of work hours. We have developed a model illustrating the emerging tension between managers' and workers' needs for WHP participation. WHP participation will likely remain low until this tension, and associated financial implications, are widely acknowledged and addressed. Our research indicates that time should be considered more explicitly and thoughtfully in the workplace engagement and WHP design, to actively respond to constraints from activity duration, scheduling and synchronisation.

Relationship between 8-year weight change, body size, and health in a large cohort of adults in Thailand.

BACKGROUND: Overweight and obesity have been shown to be risk factors for a range of non-communicable diseases, especially cardio-metabolic conditions, worldwide. But less is known about the effects of weight change on adults' overall health and wellbeing, particularly in transitional low- and middle-income countries. This study aimed to assess the relationship between 8-year weight change and measures of self-assessed health among Thai adults. METHODS: Data were collected from Thai adults aged 25-40 years (n = 27,003) enrolled in the Thai cohort Study and surveyed in 2005, 2009, and 2013. We used self-reported weight and height measurements at baseline and 2013, as well as three standard health questions regarding overall health, energy, and emotion asked at the two time points, to investigate the effects of weight change on health. RESULTS: Between 2005 and 2013, 6.0% of participants lost more than 5% of their baseline weight; 38.5% were stable (<5% loss to 5% gain); 23.0% slightly gained weight (>5%-10%); 22.8% gained moderate weight (>10%-20%); and 9.4% had heavy weight gain (>20%). Moderate (>10%-20%) and heavy weight gain (>20%) were both associated with an increased risk of reporting 'poor or very poor' overall health in 2013 among participants who had a normal body mass index (BMI) (adjusted odds ratio [AOR] 1.39; 95% confidence interval [CI], 1.13-1.71 and AOR 1.44; 95% CI, 1.09-1.90, respectively), were overweight (AOR 1.53; 955 CI, 1.01-2.29 and AOR 1.82; 95% CI, 1.04-3.19, respectively) or had obesity (AOR 2.47; 95% CI, 1.74-3.51 and AOR 3.20; 95% CI, 2.00-5.16, respectively) in 2005. Weight gain of over 20% also had a negative impact on energy level among cohort members with a normal BMI in 2005 (AOR 1.36; 95% CI, 1.11-1.65) and among participants with obesity in 2005 (AOR 1.93; 95% CI, 1.38-2.71). For those who were underweight, had a normal BMI, or had obesity at baseline, weight loss of more than 5% was associated with reporting emotional problems. Excessive weight gain adversely impacted participants who were underweight or had obesity at baseline. CONCLUSION: Our study found that weight change, in particular weight gain, was associated with negative health outcomes, and this effect appeared to increase at higher levels of body size. The present findings may be useful to promote weight maintenance and healthy lifestyles.

Australia's evolving food practices: a risky mix of continuity and change.

OBJECTIVE: To investigate trends in five key aspects of Australian food practice which have been implicated in diet-related health risks, specifically energy intake. They are: the replacement of home-prepared foods by commercially prepared foods; consumer reliance on ultra-processed foods; de-structured dining; increased pace of eating; and a decline in commensal eating. DESIGN: Data were from repeated cross-sections from the national Household Expenditure and Time Use Surveys. Trends in food practice aspects were examined using indicators of food expenditure across different food groups and time spent eating and cooking, including where, when and with whom eating activities took place. SETTING: Australia, 1989-2010. SUBJECTS: Nationally representative samples of Australian households. RESULTS: The share of the total food budget spent on food away from home rose steadily from 22·8 % in 1989 to 26·5 % in 2010, while spending on ultra-processed foods increased. The basic patterning of meals and the pace of eating changed little, although people spent more time eating alone and at restaurants. Cooking time declined considerably, particularly for women. CONCLUSIONS: These changes have occurred over the same time that obesity and diet-related, non-communicable diseases have increased rapidly in Australia. Some aspects are implicated more than others: particularly the shift from domestic cooking to use of pre-prepared and ultra-processed foods, a reduction in time spent in food preparation and cooking, as well as an upsurge in time and money devoted to eating away from home. These are all likely to operate through the higher energy content of commercially prepared, compared with unprocessed or lightly processed, foods.

Understanding barriers to fruit and vegetable intake in the Australian Longitudinal Study of Indigenous Children: a mixed-methods approach.

OBJECTIVE: To identify barriers to fruit and vegetable intake for Indigenous Australian children and quantify factors related to these barriers, to help understand why children do not meet recommendations for fruit and vegetable intake. DESIGN: We examined factors related to carer-reported barriers using multilevel Poisson models (robust variance); a key informant focus group guided our interpretation of findings. SETTING: Eleven diverse sites across Australia. SUBJECTS: Australian Indigenous children and their carers (N 1230) participating in the Longitudinal Study of Indigenous Children. RESULTS: Almost half (45 %; n 555/1230) of carers reported barriers to their children's fruit and vegetable intake. Dislike of fruit and vegetables was the most common barrier, reported by 32·9 % of carers; however, we identified few factors associated with dislike. Carers were more than ten times less likely to report barriers to accessing fruit and vegetables if they lived large cities v. very remote areas. Within urban and inner regional areas, child and carer well-being, financial security, suitable housing and community cohesion promoted access to fruit and vegetables. CONCLUSIONS: In this national Indigenous Australian sample, almost half of carers faced barriers to providing their children with a healthy diet. Both remote/outer regional carers and disadvantaged urban/inner regional carers faced problems accessing fruit and vegetables for their children. Where vegetables were accessible, children's dislike was a substantial barrier. Nutrition promotion must address the broader family, community, environmental and cultural contexts that impact nutrition, and should draw on the strengths of Indigenous families and communities.

'My child did not like using sun protection': practices and perceptions of child sun protection among rural black African mothers.

BACKGROUND: Photodamage is partially mitigated by darker skin pigmentation, but immune suppression, photoaging and cataracts occur among individuals with all skin types. METHODS: To assess practices and acceptability to Black African mothers of sun protection equipment for their children living in a rural area, participants were recruited at the time of their child's 18-month vaccinations. Mothers completed a baseline questionnaire on usual sun behaviours and sun protection practices. They were then provided with sun protection equipment and advice. A follow-up questionnaire was administered two weeks later. RESULTS: Mothers reported that during the week prior to the baseline questionnaire, children spent on average less than 1 hour of time outdoors (most often spent in the shade). Most mothers (97%) liked the sun protection equipment. However, many (78 of 86) reported that their child did not like any of the sun protection equipment and two-thirds stated that the sun protection equipment was not easy to use. CONCLUSIONS: Among Black Africans in rural northern South Africa, we found a mismatch between parental preferences and child acceptance for using sun protection when outdoors. A better understanding of the health risks of incidental excess sun exposure and potential benefits of sun protection is required among Black Africans.

Body mass index and type 2 diabetes in Thai adults: defining risk thresholds and population impacts.

BACKGROUND: Body mass index (BMI) cut-off values (>25 and >30) that predict diabetes risk have been well validated in Caucasian populations but less so in Asian populations. We aimed to determine the BMI threshold associated with increased type 2 diabetes (T2DM) risk and to calculate the proportion of T2DM cases attributable to overweight and obesity in the Thai population. METHODS: Participants were those from the Thai Cohort Study who were diabetes-free in 2005 and were followed-up in 2009 and 2013 (n = 39,021). We used multivariable logistic regression to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for the BMI-T2DM association. We modelled non-linear associations using restricted cubic splines. We estimated population attributable fractions (PAF) and the number of T2DM incident cases attributed to overweight and obesity. We also calculated the impact of reducing the prevalence of overweight and obesity on T2DM incidence in the Thai population. RESULTS: Non-linear modelling indicated that the points of inflection where the BMI-T2DM association became statistically significant compared to a reference of 20.00 kg/m2 were 21.60 (OR = 1.27, 95% CI 1.00-1.61) and 20.03 (OR = 1.02, 95% CI 1.02-1.03) for men and women, respectively. Approximately two-thirds of T2DM cases in Thai adults could be attributed to overweight and obesity. Annually, if prevalent obesity was 5% lower, ~13,000 cases of T2DM might be prevented in the Thai population. CONCLUSIONS: A BMI cut-point of 22 kg/m2, one point lower than the current 23 kg/m2, would be justified for defining T2DM risk in Thai adults. Lowering obesity prevalence would greatly reduce T2DM incidence.
