Evidence from laboratory-based in vitro studies provides compelling evidence supporting the involvement of dietary flavonoid intake in human cancer risk. Associations between intakes of individual flavonoids and disease outcomes at the population level are emerging from recent epidemiological studies. As an important step in the development of methods to assess flavonoid intakes across populations, the major sources of dietary flavonoids in the adult Australian population were identified. Data from a 24-h diet recall questionnaire used in a national nutrition survey (NNS95—comprising a sample of 10,851 subjects aged 19 yr and over) were combined with U.S. Department of Agriculture data on flavonoid content of foods to identify key sources. Black and green teas clearly were the dominant sources of the flavonols kaempferol, myricetin, and quercetin. Other significant flavonol sources included onion (isorhamnetin and quercetin), broccoli (kaempferol and quercetin), apple (quercetin), grape (quercetin), coffee (myrcetin), and beans (quercetin). Black and green teas also were dominant sources of flavon-3-ols, with wine, apples, and pears contributing somewhat. In terms of flavanone consumption, oranges (hesperetin and naringenin), lemon (eriodictyol), mandarin (hesperetin), and grapefruit (naringenin) were the major sources. Parsley (apigenin), celery (apigenin and luteolin), and English spinach (luteolin) were the major flavone sources. Wine was the major anthocyanadin source (delphinidin, malvidin, peonidin and petunidin), with smaller amounts from cherry (peonidin) and blueberry (delphinidin, malvidin, peonidin and petunidin). It is suggested that the relatively small number of aforementioned key foods form the basis of food frequency questionnaires to assess flavonoid intake.

New digital media platforms (e.g. social networking sites, web pages and text messaging) have dramatically changed interpersonal communication and present novel opportunities for health interventions. Due to the high uptake and use of digital media among young people, advances in digital media provide potential new opportunities in delivering health interventions to this audience to reduce sexually transmissible infection (STI) risk. The aim of this study was to assess the effectiveness of sexual health interventions delivered via new digital media to young people (aged 13–24 years). A systematic search was conducted of seven databases for peer-reviewed literature published between January 2010 and April 2017 that evaluated a sexual health intervention delivered to young people (aged 13–24 years). Of 2017 papers reviewed, 25 met the inclusion criteria and were assessed. Sixteen studies used web-based platforms to deliver their intervention. A large proportion of studies (11/25) specifically focused on HIV prevention. Seven studies found a statistically significant effect of the intervention on knowledge levels regarding the prevention HIV and other STI, as well as general sexual health knowledge, but only one-fifth of interventions evaluating intentions to use condoms reported significant effects due to the intervention. Nine studies focused on individuals from an African American background. Although new media has the capacity to expand efficiencies and coverage, the technology itself does not guarantee success. It is essential that interventions using new digital media have high-quality, evidence-based content that engages with individual participants.

Objective: School garden programmes have become popular action-oriented learning environments in many countries, often driven by converging priorities of environmental sustainability and healthful diets. Many of these programmes have assessed the impact on dietary intake, specifically fruit and vegetable intake, and related dietary behaviours, such as knowledge, preference, motivation, intention and self-efficacy to eat and prepare fruit and vegetables. The objective of the present study was twofold: (i) to review published garden-based programmes conducted in schools targeting dietary intake and/or determinants of dietary behaviour in children; and (ii) to identify similar strategies and components employed by these garden-based programmes.Design: The review included thirteen studies that have examined the impact of garden-based programmes conducted in school, either during school hours or in after-school settings, on dietary behaviours in children (kindergarten through 8th grade students).Results: Three of the reviewed studies did not have a comparison or control group and simply evaluated within-group changes after a garden intervention. None of the reviewed studies were randomized, but were assigned based on school’s interest and timing of new school gardens being built. Out of the eleven programmes that examined dietary intake, six found that the programme resulted in increased vegetable intake, whereas four showed no effect. Seven of the eight studies that measured preference found that the programmes resulted in increased preference for vegetables. Gardening programmes also resulted in improved attitudes towards, willingness to taste, identification of and self-efficacy to prepare/cook fruit and vegetables. Similar strategies/components employed by the majority of the programmes included: ‘hands on’ curriculum, incorporation of a cooking component, providing the instructors, parental and stakeholder support, food provision and using the garden as the focal point for media promotion.Conclusions: Some of the garden programmes resulted in increased vegetable intake, which has positive implications for both environment sustainability and health-related outcomes. Further, the majority resulted in some improvement in behaviour determinants more generally. However, more research is warranted to understand how to achieve long-term improvements in dietary behaviours and how to sustain the garden-based programmes in schools.

Objective: To estimate flavonoid intake in the Australian population. Design: Flavonoid consumption was estimated from 24-hour recall data and apparent consumption data using US Department of Agriculture flavonoid composition data. Subjects: The National Nutrition Survey 1995 assessed dietary intake (24-hour recall) in a representative sample (n = 13 858) of the Australian population aged 2 years and over. Results: Analysis of the 24-hour recall data indicated an average adult intake (>18 years) of 454 mg day− 1 (92% being flavan-3-ols). Apple was the highest quercetin source until age 16–18 years, after which onion became an increasingly important prominent source. Variations in hesperetin consumption reflected orange intake. Apple, apricot and grapes were the major sources of epicatechin and catechin for children, but subsided as wine consumption increased in adulthood. Wine was the main source of malvidin. Naringenin intake remained static as a percentage of total flavonoid intake until age 19–24 years, corresponding to orange intake, and then increased with age from 19–24 years, corresponding to grapefruit intake. Apparent dietary flavonoid consumption was 351 mg person− 1 day− 1, of which 75% were flavan-3-ols. Black tea was the major flavonoid source (predominantly flavan-3-ols) representing 70% of total intake. Hesperetin and naringenin were the next most highly consumed flavonoids, reflecting orange intake. Both 24-hour recall and apparent consumption data indicated that apigenin intake was markedly higher in Australia than reported in either the USA or Denmark, presumably due to differences in consumption data for leaf and stalk vegetables and parsley. Conclusions: Tea was the major dietary flavonoid source in Australia. Flavonoid consumption profiles and flavonoid sources varied according to age. More consistent methodologies, survey tools validated for specific flavonoid intakes and enhanced local flavonoid content data for foods would facilitate better international comparisons of flavonoid intake.

Refugees are a particularly vulnerable population who undergo nutrition transition as a result of forced migration. This paper explores how involvement in a community food garden supports African humanitarian migrant connectedness with their new country. A cross-sectional study of a purposive sample of African refugees participating in a campus-based community food garden was conducted. Semi-structured interviews were undertaken with twelve African humanitarian migrants who tended established garden plots within the garden. Interview data were thematically analysed revealing three factors which participants identified as important benefits in relation to community garden participation: land tenure, reconnecting with agri-culture, and community belonging. Community food gardens offer a tangible means for African refugees, and other vulnerable or marginalised populations, to build community and community connections. This is significant given the increasing recognition of the importance of social connectedness for wellbeing.

Objective Despite major advances in research on acute stroke care interventions, relatively few stroke patients benefit from evidence-based care due to multiple barriers. Yet current evidence of such barriers is predominantly from high-income countries. This study seeks to understand stroke care professionals’ views on the barriers which hinder the provision of optimal acute stroke care in Ghanaian hospital settings. Design A qualitative approach using semistructured interviews. Both thematic and grounded theory approaches were used to analyse and interpret the data through a synthesis of preidentified and emergent themes. Setting A multisite study, conducted in six major referral acute hospital settings (three teaching and three non-teaching regional hospitals) in Ghana. Participants A total of 40 participants comprising neurologists, emergency physician specialists, non-specialist medical doctors, nurses, physiotherapists, clinical psychologists and a dietitian. Results Four key barriers and 12 subthemes of barriers were identified. These include barriers at the patient (financial constraints, delays, sociocultural or religious practices, discharge against medical advice, denial of stroke), health system (inadequate medical facilities, lack of stroke care protocol, limited staff numbers, inadequate staff development opportunities), health professionals (poor collaboration, limited knowledge of stroke care interventions) and broader national health policy (lack of political will) levels. Perceived barriers varied across health professional disciplines and hospitals. Conclusion Barriers from low/middle-income countries differ substantially from those in high-income countries. For evidence-based acute stroke care in low/middle-income countries such as Ghana, health policy-makers and hospital managers need to consider the contrasts and uniqueness in these barriers in designing quality improvement interventions to optimise patient outcomes.
