Dietary and other lifestyle factors and their influence on non-communicable diseases in the Western Pacific region.

The Western Pacific region is a diverse region experiencing fast economic growth and nutrition transition. We systematically examined 94 cohort studies on the associations of dietary and other lifestyle factors on non-communicable diseases (NCDs) in the region. These studies were mainly from China, Japan, the Republic of Korea, and Singapore. Patterns and changes in lifestyle risk factors for NCDs based on national surveys were examined. They showed some dietary intake improvements over the past three decades, featured as increased consumption of unsaturated oils, fruits, and vegetables, and decreased consumption of sodium and unhealthy fat. Despite a decrease in smoking rate and salt intake, the values remained higher than the global levels in 2019. The ultra-processed food intake in the region increased at a higher rate than the global estimate. National guidelines relevant to NCDs in five selected countries were highlighted. Strong future actions and policies are needed to tackle NCDs.

The combination of physical activity with fruit and vegetable intake associated with life satisfaction among middle-aged and older adults: a 16-year population-based cohort study.

BACKGROUND: Life satisfaction (LS) is part of a positive psychological feeling that protects individuals from a physical decline in old age. A healthy lifestyle, including physical activity (PA) and a healthy diet, such as the intake of fruits and vegetables (F&V), can lead to a better experience of LS in older adults. However, the association between PA and F&V intake habits when occurring together in older adults is still unclear for LS. The study aimed to investigate the combined association of PA and F&V intake on LS among a cohort of older Taiwanese adults. METHODS: Five waves of population-based data gathered by the Taiwan Longitudinal Survey on Aging between 1999 and 2015 were analyzed. The year 1999 was set as the baseline, and the number of respondents was 4,440. The independent variables included the frequency, duration, and intensity of PA and the frequency of F&V intake. LS was assessed by using the Life Satisfaction Index. We performed generalized estimating equations (GEE) analysis with adjustment for covariates of health behaviors and health indicators. RESULTS: After adjusting for confounders, model 1 showed that moderate and high-PA levels significantly correlated with LS (odds ratio [OR] = 1.41, 95% CI = 1.12-1.79) and OR = 1.74, 95% CI = 1.50-2.02). Moreover, high-F&V intake significantly correlated with LS (OR = 2.07, 95% CI = 1.69-2.53). Regarding the combined association shown in model 2, compared with both the low PA and F&V intake group, there were significantly higher LS in the both-high-group (OR = 4.69, 95% CI = 3.49-6.31), only-high-F&V intake (OR = 2.87, 95% CI = 2.14-3.85), only-high-PA (OR = 2.48, 95% CI = 1.74-3.52). CONCLUSIONS: Our findings show the significant combined association of PA and F&V intake on LS among older adults. In addition, older adults who engaged in higher frequency, duration, and intensity of daily PA combined more than seven times a week of F&V intake had significantly higher LS than those who only engaged in low PA or only intake less F&V. Adopting multiple healthy behaviors in daily life is a safe and effective approach to promote LS among older adults.

Perinatal dietary patterns and symptomatic depression: A prospective cohort study.

To promote maternal and infant health, there is a need to optimise the dietary pattern of pregnant women to reduce perinatal depression. This prospective cohort study was conducted from June 2020 to February 2022, 300 women from a medical center were interviewed during late pregnancy and at 4-6 weeks postpartum. Dietary patterns were derived by factor analysis using a semiquantitative food frequency questionnaire. Symptomatic depression was defined using the Edinburgh Postpartum Depression Scale (EPDS, ranged 0-30). Their dairy, vegetable and fruit intakes were below the Taiwanese recommendations for pregnant women. Symptomatic depression (EPDS ≥10) affected 31.3% in the third trimester and 35.7% postpartum. Pre- and post-EPDS scores were positively correlated (r = 0.386, p < 0.001). Approximately 55% of those depressed before delivery were also depressed postpartum. For late pregnancy, four dietary patterns were identified ('Good oil', 'Vegetables and fruits', 'Omnivorous' and 'Refined-grain and organ meats'). Dietary patterns were classified according to quartiles (Q). Higher omnivorous pattern scores reduced the risk of depression. For prenatal depression, with Q1 as a reference, the risk was reduced by 38% for Q2, 43% for Q3 and 59% for Q4 (p for trend = 0.068). These findings became evident postpartum (reduced risk by 68% for Q2, 69% for Q3 and 70% for Q4 (p = 0.031; p for trend = 0.0032). The association between dietary patterns and depression encourages the routine nutritional management of pregnant women.

Three-dimensional food printing: its readiness for a food and nutrition insecure world.

Three-dimensional (3D) food printing is a rapidly emerging technology offering unprecedented potential for customised food design and personalised nutrition. Here, we evaluate the technological advances in extrusion-based 3D food printing and its possibilities to promote healthy and sustainable eating. We consider the challenges in implementing the technology in real-world applications. We propose viable applications for 3D food printing in health care, health promotion and food waste upcycling. Finally, we outline future work on 3D food printing in food safety, acceptability and economics, ethics and regulations.

Mapping the human gut mycobiome in middle-aged and elderly adults: multiomics insights and implications for host metabolic health.

OBJECTIVE: The human gut fungal community, known as the mycobiome, plays a fundamental role in the gut ecosystem and health. Here we aimed to investigate the determinants and long-term stability of gut mycobiome among middle-aged and elderly adults. We further explored the interplay between gut fungi and bacteria on metabolic health. DESIGN: The present study included 1244 participants from the Guangzhou Nutrition and Health Study. We characterised the long-term stability and determinants of the human gut mycobiome, especially long-term habitual dietary consumption. The comprehensive multiomics analyses were performed to investigate the ecological links between gut bacteria, fungi and faecal metabolome. Finally, we examined whether the interaction between gut bacteria and fungi could modulate the metabolic risk. RESULTS: The gut fungal composition was temporally stable and mainly determined by age, long-term habitual diet and host physiological states. Specifically, compared with middle-aged individuals, Blastobotrys and Agaricomycetes spp were depleted, while Malassezia was enriched in the elderly. Dairy consumption was positively associated with Saccharomyces but inversely associated with Candida. Notably, Saccharomycetales spp interacted with gut bacterial diversity to influence insulin resistance. Bidirectional mediation analyses indicated that bacterial function or faecal histidine might causally mediate an impact of Pichia on blood cholesterol. CONCLUSION: We depict the sociodemographic and dietary determinants of human gut mycobiome in middle-aged and elderly individuals, and further reveal that the gut mycobiome may be closely associated with the host metabolic health through regulating gut bacterial functions and metabolites.

Nutrition counseling is associated with less sarcopenia in diabetes: A cross-sectional and retrospective cohort study.

OBJECTIVES: Muscle is crucial for blood glucose regulation. There is a need to prevent and treat sarcopenia in diabetes mellitus (DM). This study aimed to estimate the prevalence of sarcopenia and evaluate the association of nutritional counseling with the development of sarcopenia for people with DM. METHODS: In a cross-sectional and retrospective cohort study, people with type 2 DM were recruited from the Diabetes Shared Care Program of a teaching hospital. Muscle mass, muscle strength, and physical functional performance were evaluated using the Asian Working Group for Sarcopenia criteria. The skeletal muscle mass index was determined by dividing muscle mass by the square of the height. Clinical information, including the nutrition counseling record, was retrospectively obtained from medical records for a 2-y period. RESULTS: The prevalence of low skeletal muscle mass index (presarcopenia) and sarcopenia were, respectively, 20.4% and 9.6% (including 3.1% severe) among 1292 participants. Specifically, 15.3% of participants age ≥ 65 y were categorized as having sarcopenia. With more frequent nutritional counseling, there was a lesser risk of sarcopenia; the adjusted odds ratio (95% confidence interval) was 0.51 (0.27-0.94) for ≥ 3 times/2 y compared to no counseling. DM duration and age, glycemic status and medication, and body mass index and counseling frequency had no joint effects; however, these variables (except HbA1 c) were independent risk factors for low skeletal muscle mass index and sarcopenia. CONCLUSIONS: People with type 2 DM have a high risk of sarcopenia. Increased nutrition counseling in outpatients was associated with less sarcopenia. Education about sarcopenia-associated risk factors should be encouraged early in the onset of DM.

Household and schooling rather than diet offset the adverse associations of height with school competence and emotional disturbance among Taiwanese girls.

OBJECTIVE: Short stature may reflect health in early life and be an enduring disability. How birth weight, gender, household, elementary schooling and diet play a role in associations between stature and overall school competence (OSC) have been assessed. DESIGN: The 2001-2002 Nutrition and Health Survey in Taiwan (NAHSIT) for elementary schoolchildren (n 2274, 52·1 % boys) was linked to birth records. It provided sociodemographic, dietary quality, body compositional and school performance (as Scale for Assessing Emotional Disturbance, SAED; OSC as an SAED subscale) data. Lower birth weight was ≤15th percentile: 2850 g for boys and 2700 g for girls, and stature as z-scores for Taiwanese. Multivariable linear regression was used for relationships between OSC and stature. Trends in OSC by stature and school grade were assessed. SETTING: The 2001-2002 NAHSIT for elementary schoolchildren. PARTICIPANTS: Totally, 2274 schoolchildren aged 6-13 years. RESULTS: Compared to normal height (-2< height for age z-score (HAZ) <2), shorter girls (HAZ ≤ -2) had a lower OSC (8·87 v. 10·5, P < 0·05) and taller girls (HAZ ≥ 2) had a better OSC (12·3 v. 10·5, P < 0·001). Maternal education and household income each contributed more than 5 % of OSC variance. OSC and HAZ among girls were positively associated and emotional disturbance negatively associated. Shortness-associated lower OSC underwent remediation with advancing school grade. Stature and OSC were not evidently related in boys. CONCLUSIONS: Shorter stature can compromise OSC among school girls. The major determinants in shorter girls are less household income and limited parental education.

Higher maternal autonomy is associated with reduced child stunting in Malawi.

Child undernutrition is a major health problem in Malawi. We assessed the association between maternal autonomy and child stunting in Malawi. We utilized nationally representative pooled cross-sectional data from the 2010 and 2015/16 Malawi Demographic and Health Surveys (MDHS), which included 7348 mother (28.1 ± 6.8 years, range 15-49 years)-child (27.6 ± 16.7 months, range 0-59 months) pairs. Maternal autonomy composite scores captured decision-making power, tolerance of domestic violence, and financial independence. The nutritional outcome measure was stunting (height-for-age z score < - 2). Logistic regression assessed associations between maternal autonomy and stunting, and dominance analysis evaluated the relative importance of the associated factors. From the two surveys combined, 39.2% were stunted. Stunting decreased from 45.0% in 2010 to 34.6% in 2015/16; concurrently, maternal autonomy improved and was evidently associated with stunting (aOR = 0.81, 95% CI = 0.71, 0.93; p = 0.002). However, this association was probably mediated by other factors associated with improved child nutrition, including maternal education and family wealth, which, along with child age, were associated with stunting in the dominance analysis. Concurrent interventional programs may also have contributed to the decrease in stunting between the surveys, thus moderating the effect of maternal autonomy.

Optimal Household Water Access Fosters the Attainment of Minimum Dietary Diversity among Children Aged 6-23 Months in Malawi.

Along with sanitation and hygiene, water is a well-known driver of child undernutrition. However, a more direct role of household (HH) water access in shaping dietary diversity remains unexplored. We assessed the association between HH water access and achievement of minimum dietary diversity (MDD) among young children. We utilized nationally-representative cross-sectional data from the 2015/16 Malawi Demographic and Health Survey, which included 4727 mother-child dyads, respectively, (26.8 ± 6.8 years, range 15-49 years) and (13.9 ± 4.9 months, range 6-23 months). HH water access was categorized as (1) basic or no access, (2) intermediate, or (3) optimal. MDD was defined as feeding a child, during the previous day, at least four of the food groups defined by the World Health Organization. Only 27.7% of the children achieved MDD standards; most of the children who achieved MDD were from HHs with optimal water access (58.4%, p < 0.001). However, only 5.9% of the mother-child dyads were from HHs with optimal water access. After adjusting for covariates, children from HHs with optimal water access had higher odds of achieving MDD than those from HHs with basic or no water access (aOR = 1.74, CI = 1.24-2.46). Our results highlight the need to incorporate water-based strategies into national nutritional policies to increase dietary diversity among Malawian infants and young children.

Imagining a habitable planet through food and health.

BACKGROUND AND OBJECTIVES: Whether and how it might be possible to imagine a habitable planet through food and health. METHODS: Reflection on childhood happenstances, sociodemographic circumstances, educational opportunities, persons of influence and lifetime experiences insofar as they might have shaped a view of the past, present and future world as the sole rational home of us all. Confirmation of these notions by personal, kindred, and other contemporary records and publications. RESULTS: The need to live with uncertainty and an appreciation of connectedness with things animate and inanimate; and for this to be belief, identity, reason and professional imprimatur. That these things have unwittingly informed a near lifetime of interest and enthusiasm for how food and health systems are best served by socioecological approaches. CONCLUSIONS: That we are socioecological beings with a destiny dependent on reconciling ourselves, as earthlings, as to how well we keep our place in the cosmos habitable. To that end we must dream and work.

Econutrition, brown and beige fat tissue and obesity.

BACKGROUND AND OBJECTIVES: Obesity is caused by excessive fat accumulation or abnormal fat distribution and has become one of the biggest health challenges worldwide. Considering the high thermogenic ability of brown fat tissue (BAT) and the plasticity of fat tissue, to induce the browning of white fat tissue (WAT), so increasing BAT activity provides an attractive option for the prevention and resolution of obesity. The aim of the present narrative review was to understand the relationship between diet, BAT, and obesity. METHODS AND STUDY DESIGN: PubMed and Embase databases were searched to identify eligible studies. RESULTS: Although cold exposure has long been known to be effective in the browning of WAT and activation of BAT, it is societally impractical for everyday body weight management aside from the tolerance of ambient temperature. An alternative is to identify specific dietary components with similar effects to cold exposure on BAT. Current evidence indicates that capsaicin and capsinoids, catechins, curcumin, quercetin, berberine, lipoic acid, polyunsaturated fatty acids, royal jelly, and some natural sweeteners are effective promoters of WAT browning, increase BAT activity and improve obesity related traits. However, only capsaicin, capsinoids, and catechins have demonstrated efficacy in clinical trials. Evidence for effects of curcumin, quercetin, berberine, lipoic acid, polyunsaturated fatty acids, royal jelly and natural sweeteners on BAT have only been observed in animal or in vitro studies, with clinical trials awaited for verification. CONCLUSIONS: Several dietary components can induce WAT browning and activate BAT, offering potential targets for obesity prevention and management.

Intersectoral and eco-nutritional approaches to resolve persistent anemia in Indonesia.

Anemia in Indonesia has been of concerning persistence in all age groups for some 75 years since independence. The relationships between anemia and nutrition are complex being evident with compromised general health and nutrition. Increased micronutrient intakes, especially iron and folic acid, has alleviated the problem, but encouraged nutrient-specific micronutrient interventions as attractive policy directions as if anemia were a stand-alone disease irrespective of associated disorder. Concerted action to deal with the fundamental causality has been missing. Much of the pathogenetic pathway may be nutritional, but its multifactoriality is ultimately socioecological. Given the intransigence and progression of societal and ecosystem dysfunction, it can be expected that failure to recognize their causal importance will further entrench endemic anemia. This review deliberates the practical measures taken to recognize anemia by symptomatology, food and nutrition surveys, screening (fingerpick blood), nutrition assessment, and blood loss (menstrual and faecal). It identifies vulnerable groups including premenopausal and pregnant women, children and adolescents, unwell adults, and the dependent aged. Risk settings include food insecurity, infectious disease, non-communicable disease, inheritance and epigenetics, and socioeconomic disadvantage. Underlying socio-ecological problems are livelihood, food systems, cultural habits, belief systems, and social networks and activities. With this framework, policy directions could deal more comprehensively and effectively with the socioecological complexity which underpins and limits progress towards anemia eradication at a time of intense global food and health insecurity. It will require co-operative intersectoral and eco-nutritional approaches which take into account the need for universal, sustainable livelihoods. Recommendations have been made accordingly.

Non-nutritional anemia: Malaria, thalassemia, G6PD deficiency and tuberculosis in Indonesia.

Anemia affects people worldwide and results in increased morbidity and mortality, particularly in children and reproductive-age women. Anemia is caused by an imbalance between red blood cell (RBC) loss and production (erythropoiesis), which can be caused by not only nutritional factors but also non-nutritional factors, such as inflammation and genetics. Understanding the complex and varied etiology of anemia is crucial for developing effective interventions and monitoring anemia control programs. This review focusses on two interrelated nonnutritional causes of anemia: malaria infection and RBC disorders (thalassemia and G6PD deficiency), as well as tuberculosis. According to the Haldane hypothesis, thalassemia occurs as a protective trait toward malaria infection, whereas G6PDd arises in malaria-endemic regions because of positive selection. Indonesia is a malariaendemic region; thus, the frequency of thalassemia and G6PD deficiency is high, which contributes to a greater risk for non-nutritional anemia. As Indonesia is the second global contributor to the newly diagnosed tuberculosis, and active pulmonary tuberculosis patients are more anemic, tuberculosis is also contributes to the increasing risk of anemia. Therefore, to reduce anemia rates in Indonesia, authorities must consider non-nutritional causes that might influence the local incidence of anemia, and apply co-management of endemic infectious disease such as malaria and tuberculosis, and of genetic disease i.e. thalassemia and G6PDd.

Self-monitoring networks for personal and societal health: Dietary patterns, activities, blood pressure and Covid-19.

The contributors to and consequences of disordered health are increasingly complex with sociodemographic, ecological, economic and food system change. But there are opportunities for any adversity to be mitigated by advances in the understanding of human, especially nutritional, ecobiology and in its more accessible and affordable evaluation and monitoring. Viral pandemics are on the rise with climate change and loss of ecosystems. They threaten human civilisation and planetary habitability. Human security is dependent on sustainable livelihoods of which food and water systems are a vital part. We are socioecological beings and depend for our health on biodiversity and the food diversity that ensures; and on connectedness and communication, made more difficult in pandemics. Rapid and accessible point-of-care (POC) tools are now becoming available to compliment other selfmonitoring network approaches, whether checklist or questionnaire, physical, chemical, or biological, for healthcare and nutritional health. They can provide information as several complimentary and interdependent health indices to facilitate personal, group and community action and management plans. This applies to indices of both communicable and non-communicable disease which problems separately and together are compromising health prospects. These indices include ones of physical and mental activities, dietary patterns, metabolites, blood pressure and now the presence and severity of viruses like Covid-19.Of imminent relevance and promise are optically- readable biosensor based strips for nasal, pharyngeal or salivary samples to check viral presence or finger prick blood for immunoglobulins and interleukins. These should allow less socially prohibitive measures to curb viral transmission and promote personal and societal wellbeing.

Dietary patterns and anemia morphology in young men and women in Shandong province, China.

BACKGROUND AND OBJECTIVES: The association between diet and macrocytic and hypochromic anemia in young Chinese men and women remains unclear. The present study aimed to investigate the relationship between dietary pattern and macrocytic and hypochromic microcytic anemia in young Chinese men and women. METHODS AND STUDY DESIGN: Some 4,840 first-year students (2,385 men and 2,455 women) were recruited for this study from Qingdao University, China. Biochemical and hematological parameters, and food frequency questionnaires were obtained from the subjects. Based on dietary intake, participants were divided into three dietary patterns: seafood dietary pattern (SDP), vegan dietary pattern (VDP) and omnivorous dietary pattern (ODP). The risks for macrocytic and microcytic hypochromic anemia in three dietary patterns were assessed. RESULTS: Macrocytic and hypochromic anemia were less common in participants who adhered to the omnivorous dietary pattern than to the vegan or seafood dietary patterns (p<0.05). Adhering to an omnivorous dietary pattern was negatively associated with macrocytic anemia in men [odds ratio (95% CI): 0.74 (0.62, 0.89), p<0.001] and microcytic, hypochromic anemia in both genders [men: odds ratio (95% CI): 0.64 (0.45, 0.92), p=0.01; women: odds ratio (95% CI): 0.71 (0.51, 0.99), p=0.04]. CONCLUSIONS: Adhering to an omnivorous dietary pattern was associated with less common macrocytic anemia in young men and microcytic, hypochromic anemia. Dietary diversity is important in preventing macrocytic anemia in men and also microcytic, hypochromic anemia in young men and women. Excessive alcohol intake is the most plausible explanation for macrocytosis in the young men.

Covid-19 and dietary socioecology: Risk minimisation.

Pandemics have shaped humanity over and over again, but the coronavirus outbreak of 2019-2020 is in a world at the tipping point of catastrophic climate change. Its origins and distinction derive from over-population with inequity and an industrial revolution since the 17th century which has exploited fossil fuels as a globalised energy source, a period now described as the anthropocene. Asymptotic ecosystem loss and dysfunction, for people whose being is socioecological, makes ultimate survival tenuous. Microbial forms of life jump species when habitats are destroyed, or their host misused. Our innate immunity depends on our general health and fitness- social, mental, physical, and nutritional, in step with nature and its rhythms through walking in it, enjoying sunlight and sleep. Biodiversity and the associated benefit of food variety, after being breast-fed, is the key descriptor of a healthful, sustainable, accessible, and acceptable way of eating. How this pattern might contribute to our resilience in the face of a highly transmissible and biologically evasive virus is becoming clear. It may also be possible to compliment usefully preventive vaccination and therapeutic healthcare and rehabilitation through a greater understanding of our nutritional biology.

Benefit risk and cost ratios in sustainable food and health policy: Changing and challenging trajectories.

There is benefit, risk and cost in all that we do, but when it comes to food, we expect that it will benefit our health, be available, safe to eat and affordable. But as climate change and demographic shifts through displacement and ageing gather momentum, the emphases on each of benefit, risk and cost will alter. That we are ecological beings whose health and wellbeing are ecosystem-dependent, must now be the underpinning framework for risk management. Loss of natural environment and biodiversity represents reduced nutritional and health resilience, which will need to be factored in to risk assessment and management with climate change. This is proving a problematic risk communication challenge. Previously desirable food and food pattern recommendations will be tempered by substantial sustainability, availability, safety, affordability, equity and ethical considerations. Future workforces will need to ensure basic livelihoods (food, water, shelter, clothing, healthcare, education, communication, essential transport, resource management and effective governance) and with risk minimisation. Cost appraisal will have less to do with monetisation and more to do with resource management in accordance with equity and ethical principles. Communities could adopt Liveability Units (LU) for traceability and community-based transactions, as a currency for a more sustainable future, encouraging and enabling food and health system viability. Open source food and health systems, supported by LU matrix (bar code or QR) scanning with smartphones could be widely available for individual, household and community benefit, risk and cost management. The risk is remoteness from food's origins and megadata commercialisation.

Regulobiosis: A regulatory and food system-sensitive role for fungal symbionts in human evolution and ecobiology.

The role of microbiomes in human biology and health are being extensively investigated, yet how the fungal community or mycobiome contributes to an integral microbiome is unclear and probably underestimated. We review the roles of fungi from the perspectives of their functionality in human biology, their cross-kingdom talk with other human microbial organisms, their dependence on diet and their involvement in human health and diseases. We hypothesize that members of the fungal community may interact as necessary symbionts with members of other human microbiome communities, and play a key role in human biology, yet to be fully understood. We propose further that "regulobiosis", whereby fungi play a regulatory role in human ecobiology, is operative in humans as probably obtains in other forms of life. Fungally-dependent regulobiosis would characterise, at first, microbiomes which include, but are not limited to, bacteria, archaea, and viruses; then, their human host; and, next, provide ecological connectedness.

Dietary diversity offsets the adverse mortality risk among older indigenous Taiwanese.

BACKGROUND AND OBJECTIVES: The extent to which health and survival inequality between indigenous and nonindigenous older Taiwanese is associated with diet is uncertain. METHODS AND STUDY DESIGN: Participants from the Elderly Nutrition and Health Survey in Taiwan (1999-2000) formed this cohort. Dietary information was collected by 24-hr recall and simplified food frequency questionnaire. Dietary quality was assessed by dietary diversity score (DDS, 0-6). Annual medical service utilization and expenditure were derived from National Health Insurance claims until 2006. Survivorship was ascertained from the National Death Registry until 2008. Cox proportional- hazards models were used to determine the association between aboriginality and mortality in conjunction with dietary diversity. RESULTS: Indigenes (n=156) compared with nonindigenes (n=1182) significantly differed in socio-demography, behaviors and chronic disease prevalences. For up to 8 years, indigenes had a higher mortality rate (46.2% vs 33.6%, p=0.003). Indigenes' nutrient intakes were less for polyunsaturated fat, dietary fiber, vitamins and minerals (but more sodium); food intakes more for meat, with less cooking oil, dairy products and fruits; and a lower DDS, (3.61 vs 4.54). They had a 41% higher mortality risk (HR: 1.41, 95% CI: 1.09-1.81, p=0.008). Control for demographic variables did not change the findings. However, the increase in HR was substantially attenuated by the inclusion of DDS (HR: 1.15, 95% CI: 0.88-1.49, p=0.316). There was no significant interaction between aboriginality and DDS on mortality (p=0.673). CONCLUSIONS: Older indigenous Taiwanese have a higher mortality risk than their majority counterparts. Irrespective of aboriginality, the more diverse diet is associated with a lower risk of mortality.
