The current study aimed to characterise the food profile of Yanomami indigenous children according to the degree of food processing and its associated factors.

This is a cross-sectional study with Yanomami indigenous children aged 6 to 59 months. Socio-demographic, maternal and infant data were collected through a standardised questionnaire. The food profile was obtained by using a list of thirty-four foods to verify the child’s consumption of these foods on the day preceding the interview. Foods were classified according to the degree of processing based on the NOVA system (in natura or minimally processed, processed culinary ingredients, processed and ultra-processed). In natura and minimally processed foods were subdivided into ‘regional’ and ‘urban’ foods. Poisson regression analysis was applied to estimate the associated factors according to the 90 % CI.

Three villages (Auaris, Maturacá and Ariabú) in the Yanomami indigenous territory, in the Brazilian Amazon.

In total, 251 Yanomami children aged 6 to 59 months were evaluated.

The prevalence of consumption of ‘regional’ and ‘urban’ in natura or minimally processed foods was 93 % and 56 %, respectively, and consumption of ultra-processed foods was 32 %. Ultra-processed food consumption was 11·6 times higher in children of Maturacá and 9·2 times higher in Ariabú when compared with the children of Auaris and 31 % lower in children who had mothers with shorter stature.

Despite the high frequency of consumption of in natura and minimally processed foods, the consumption of ultra-processed foods was substantial and was associated with demographic and maternal factors in Yanomani indigenous children under 5 years of age.

The mental health status of indigenous people in Bangladesh has attracted little or no attention. The objective of the present study is to determine the extent of symptoms of anxiety and depression in the two largest indigenous communities in Bangladesh.

In total, 240 participants were recruited, 120 from each of the Marma and Chakma communities with an overall mean age of 44.09 years (s.d. 15.73). Marma people were older (mean ages 48.92 v. 39.25, p < 0.001). Participants completed the Anxiety Scale (AS) and Depression Scale (DS) that have been developed and standardised in Bangladesh in the Bangla (Bengali) language.

Results indicated that anxiety and depression scores were elevated in both communities, 59.2% of the participants scoring above the cut-off for clinical significance on AS and 58.8% of the participants scoring above the cut-off for clinical significance on DS. Marma people compared to Chakma people were more anxious (M = 59.49 v. 43.00, p < 0.001) and more depressed (M = 106.78 v. 82.30, p < 0.001). The demographic variables of age, sex and socioeconomic status were weakly or inconsistently related to scores. In the Marma people, females scored higher on both AS and DS, but in the Chakma community, males scored higher on AS and the same on DS.

The finding of significant anxiety and depression in communities with such limited mental health services is a matter of concern and emphasises the need to formulate and implement appropriate mental health policies for indigenous people in Bangladesh and other parts of the world.

To develop an online food composition database of locally consumed foods among an Indigenous population in south-western Uganda.

Using a community-based approach and collaboration with local nutritionists, we collected a list of foods for inclusion in the database through focus group discussions, an individual dietary survey and markets and shops assessment. The food database was then created using seven steps: identification of foods for inclusion in the database; initial data cleaning and removal of duplicate items; linkage of foods to existing generic food composition tables; mapping and calculation of the nutrient content of recipes and foods; allocating portion sizes and accompanying foods; quality checks with local and international nutritionists; and translation into relevant local languages.

Kanungu District, south-western Uganda.

Seventy-four participants, 36 Indigenous Batwa and 38 Bakiga, were randomly selected and interviewed to inform the development of a food list prior the construction of the food database.

We developed an online food database for south-western Uganda including 148 commonly consumed foods complete with values for 120 micronutrients and macronutrients. This was for use with the online dietary assessment tool myfood24. Of the locally reported foods included, 56 % (n 82 items) of the items were already available in the myfood24 database, while 25 % (n 37 items) were found in existing Ugandan and Tanzanian food databases, 18 % (n 27 items) came from generated recipes and 1 % (n 2 items) from food packaging labels.

Locally relevant food databases are sparse for African Indigenous communities. Here, we created a tool that can be used for assessing food intake and for tracking undernutrition among the communities living in Kanungu District. This will help to develop locally relevant food and nutrition policies.

To understand non-adherence to medically recommended diets among Mayans with diabetes.

Using partially sequential mixed methods, questionnaires, semi-structured brief and in-depth interviews were applied. Questionnaire data were analysed with Pearson’s χ2 and Student’s t tests and qualitative interviews with grounded theory microanalysis.

Rural, predominantly Mayan communities in Chiapas, Quintana Roo and Yucatan, Mexico, 2008–2012.

Purposive sample of Mayans with type 2 diabetes; using public health care; 168 women and twenty-seven men; age 21–50+ years.

Participants understood diabetes as caused by negative emotions, divine punishment, revenge via spells, chemicals in food and high sugar/fat consumption. Eliminating corn, pork, sugary beverages and inexpensive industrialized foods was perceived as difficult or impossible. More Mayans reporting not understanding physician instructions (30 v. 18 %) reported difficulty reducing red meat consumption (P = 0·051). Non-adherence was influenced by lack of patient–provider shared knowledge and medical recommendations misaligned with local culture. Men whose wives prepared their meals, women who liked vegetables and young adults whose mothers prepared their meals reported greater adherence to dietary recommendations. Partial adherents said it made life tolerable and those making no physician-recommended dietary changes considered them too restrictive (they meant ‘starving to death’). Over half (57 %) of participants reported non-adherence; the two principal reasons were dislike of recommended foods (52·5 %) and high cost (26·2 %).

Adherence to dietary regimens in diabetes treatment is largely related to social and cultural issues. Taking cultural diversity, food preferences, local food availability and poverty into consideration is essential when developing health-promotion activities related to diabetes.

To review research addressing the polymicrobial aetiology of otitis media in Indigenous Australian children in order to identify research gaps and inform best practice in effective prevention strategies and therapeutic interventions.

Literature review.

Studies of aspirated middle-ear fluid represented a minor component of the literature reviewed. Most studies relied upon specimens from middle-ear discharge or the nasopharynx. Culture-based middle-ear discharge studies have found that non-typeable Haemophilus influenzae and Streptococcus pneumoniae predominate, with Moraxella catarrhalis, Staphylococcus aureus and Streptococcus pyogenes isolated in a lower proportion of samples. Alloiococcus otitidis was detected in a number of studies; however, its role in otitis media pathogenesis remains controversial. Nasopharyngeal colonisation is a risk factor for otitis media in Indigenous infants, and bacterial load of otopathogens in the nasopharynx can predict the ear state of Indigenous children.

Most studies have used culture-based methods and specimens from middle-ear discharge or the nasopharynx. Findings from these studies are consistent with international literature, but reliance on culture may incorrectly characterise the microbiology of this condition. Advances in genomic technologies are now providing microbiologists with the ability to analyse the entire mixed bacterial communities (‘microbiomes’) of samples obtained from Indigenous children with otitis media.

To determine whether the use of tissue spears to remove otorrhoea from Aboriginal children's ear canals improves hearing in the affected ear.

Case series study with controls.

The study comprised 61 Aboriginal children from communities in the remote arid zone of South Australia who had otorrhoea obscuring the tympanic membrane in 1 or both ears. Eighty ears were treated with tissue spears, and hearing was assessed before and after treatment.

Forty-two children had unilateral and 19 had bilateral active disease. An additional 13 ears without otorrhoea served as controls. Improvement by 5 dB HL or greater in a four-frequency pure tone average occurred in 41.3 per cent of treated ears. Subsequently, blinded audiologists made qualitative judgements that a functional improvement in hearing had occurred after tissue spear use in 28.4 per cent of ears.

Tissue spears can improve hearing thresholds in a significant proportion of children with otorrhoea. However, the duration of the effect is unknown.

To determine associations of diet, physical activity and television (TV) viewing time with obesity among aboriginal and non-aboriginal youth in conjunction with socio-economic variables.

Cross-sectional study of differences between aboriginal and non-aboriginal groups and associations between lifestyle and socio-economic factors with obesity were examined.

Population data from the Canadian Community Health Survey Cycle 2·2 conducted in 2004 in the ten provinces of Canada.

A total of 198 aboriginal and 4448 non-aboriginal Canadian youth aged 12–17 years.

Compared to non-aboriginal youth, physical activity participation among aboriginal youth was higher, but consumption of vegetables and dairy products was lower, and more aboriginal youth were ‘high’ TV watchers. Low income adequacy was associated with decreased odds for obesity among aboriginal youth in contrast to higher odds among non-aboriginal youth. Non-aboriginal ‘high’ TV watchers consumed more soft drinks and non-whole-grain products than did ‘low’ TV watchers. Physical activity participation did not differ between ‘high’ and ‘low’ TV watchers for both groups, and was associated with lowered odds for obesity only among aboriginal youth.

Sociodemographic and lifestyle risk factors associated with obesity differ between aboriginal and non-aboriginal youth. These findings may be useful for guiding intervention efforts.
