Utilization of Traditional Complementary and Alternative Medicine Across Ethnically Diverse Asian Americans.

We conducted an analysis to identify factors influencing the use of traditional complementary and alternative medicine (TCAM), with a particular emphasis on ethnic variations. Using the 2015 Asian American Quality of Life survey (N = 2,609), logistic regression analyses were performed, considering acculturation, health status, healthcare accessibility/utilization, and socio-demographic factors. Ethnicity, specifically being Chinese or Korean Americans, having chronic medical conditions, experiencing unmet healthcare needs, and having regular check-ups were significant predictors of TCAM use among Asian Americans as a whole. However, when we delved into sub-ethnic groups, different patterns were found. Among Vietnamese and Filipino Americans, having unmet healthcare needs emerged as the most prominent predictor of TCAM use. Furthermore, acculturation level and English proficiency were significant in predicting Vietnamese and Filipino Americans' TCAM use, with the direction varying by sub-ethnicity. Being old emerged as a predictor of TCAM use for Chinese, Indian, Korean, and 'other' Americans. Our findings underscore the importance of adopting an ethnically sensitive approach when addressing the healthcare needs of diverse Asian American populations.

African Immigrants' perceptions and attitudes toward cardiovascular health.

AIM: To explore perceptions and attitudes of African immigrants (Ghanaians, Nigerians, Liberians, and Sierra Leoneans) in the Baltimore-Washington, DC, metropolitan area toward cardiovascular health. METHODS: This was a qualitative study among African immigrants recruited from religious and community-based organizations in the Baltimore-Washington metro area. A purposive sample of 66 African immigrants originally from Ghana, Nigeria, Liberia, and Sierra Leone completed a sociodemographic survey and participated in focus group discussions. Focus group data were analysed using qualitative description to develop emergent themes. RESULTS: A total of 66 African immigrants with a mean (±standard deviation) age of 51 (±11.8) years participated in the focus group discussions. Fifty percent were women, 91% had at least a bachelor's degree, 84% were employed, 80% had health insurance, and 75% were married/cohabitating. The majority of the participants (74%) had lived in the US for 10 years or more, 44% of them had hypertension, and 12% had diabetes. Findings from the focus group discussions revealed: gender differences in descriptions of cardiovascular health and healthiness, an emotional response associated with cardiovascular disease (evoking fear and anxiety and associated with family secrecy), positive and negative lifestyle changes after migration, cardiovascular screening behaviours, and facilitators and barriers to cardiovascular disease prevention practices and heart-healthy lifestyle. CONCLUSIONS: Participants understood health to be a holistic state of well-being. Secrecy in disclosing their cardiovascular disease diagnoses informed by historical socio-cultural belief systems, perceived racial discrimination by healthcare providers, communication and health literacy barriers, economic barriers of holding multiple jobs and the exorbitant cost of heart-healthy foods were identified as some barriers to achieving optimal cardiovascular health in this immigrant population. IMPACT: Our study expanded on the body of knowledge on African immigrants' perceptions and attitudes toward cardiovascular health. Addressing this knowledge gap will provide important intervention opportunities targeted at improving cardiovascular health outcomes in this population. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

Moving the Needle in Gout Management: The Role of Culture, Diet, Genetics, and Personalized Patient Care Practices.

Gout is a metabolic disorder, and one of the most common inflammatory arthritic conditions, caused by elevated serum urate (SU). Gout is globally rising, partly due to global dietary changes and the growing older adult population. Gout was known to affect people of high socioeconomic status. Currently, gout disproportionately affects specific population subgroups that share distinct racial and ethnic backgrounds. While genetics may predict SU levels, nongenetic factors, including diet, cultural traditions, and social determinants of health (SDOH), need to be evaluated to optimize patient treatment outcomes. This approach would allow clinicians to assess whether certain cultural norms, or some SDOH, could be contributing to their patient's risk of developing gout or recurrent gout flares. A cultural assessment may inform the development of culturally tailored dietary recommendations for patients with gout. Causal and association studies investigating the interaction between diet, genetics, and gout, should be cautiously interpreted due to the lack of reproducibility in different racial groups. Optimal gout management could benefit from a multidisciplinary approach, involving pharmacists and nurses. While data on the effect of specific dietary recommendations on managing hyperuricemia and gout may be limited, counseling patients with gout on the role of a healthy diet to optimally control their gout flares and other comorbidities should be part of patient education. Future research investigating the role of a gene-diet interaction in the context of hyperuricemia and gout is needed. Optimal care for patients with gout needs to include a holistic assessment for gout and gout-related comorbidities. Additionally, addressing health beliefs and culture-specific lifestyle factors among patients with gout may reduce their risk of gout flare, improve adherence to urate-lowering therapy (ULT), and achieve health equity in gout management.

Dietary acculturation of international students in Pune, India: a cross-sectional study.

BACKGROUND: Dietary acculturation refers to how a migrant group adopts the eating patterns of the host country. It results in changes in dietary behavior, dietary intake, and nutritional status of this vulnerable group. AIM: To study dietary acculturation of international students in Pune, India. METHODS: International students from three Universities in Pune were enrolled. Information on demography, dietary behavior, and dietary intake (using a food frequency questionnaire) was recorded using an interviewer-administered questionnaire. The height and weight of the students were measured using standard, calibrated equipment. The data were analyzed using descriptive and analytical statistics. RESULTS: A total of 100 international students from Iran, Africa, and South Korea were grouped by nationality. Considerable variation was detected in the daily number of meals consumed, skipping meals, portion size changes, packaged food consumption, and supplement intake following migration between the groups. The intake of non-vegetarian food had declined drastically for all groups. However, the specific non-vegetarian item showing the greatest change differed according to the group's nationality. The intake of biscuits and cake had increased among all groups. African students showed an increase of 3.33 kg in body weight following migration. The intake of protein and micronutrients declined for all groups. CONCLUSIONS: This study highlights the changes in dietary behavior, dietary intake, and nutritional status of international students of different nationalities following migration to Pune, India. Thus, it emphasizes the need for nutrition interventions in international students in India.

Acculturation and use of traditional medicine among African migrant women in Sydney: a mixed method study.

BACKGROUND: More than 80% of the African population depend on traditional medicine as a primary healthcare. Although the African migrant community is increasing in Australia, there is no research documenting if and how African migrant communities have maintained or changed their use of traditional health practices after migration. This study aims to answer the following research questions: does acculturation influence the use of traditional medicine? and how are cultural health practices or beliefs manifested among African migrant women in Australia? METHOD: A mixed methods design which involved a cross-sectional survey (n = 319) and individual interviews (n = 15) was conducted. Survey data were analysed using SPSS (version 23) and logistic regression model was used to test associations. Qualitative data were analysed thematically using NVivo 11 software to identify themes and conceptual categories in the participants' responses. The study was informed by acculturation theory. RESULT: Both the survey and the interview data indicated that cultural health practices were retained as an important form of healthcare for African migrant women in Sydney. The findings indicated that African migrants continued to use traditional medicines as part of their cultural identity and to build cohesive ethnic community to share traditional values and cultural practices. Women who relatively stayed for shorter period of time in Australia and migrated at a later age were more likely to use TM. CONCLUSION: Acculturation proxy measures increased the likelihood of TM use suggesting African migrant women retain their cultural health practices in Australia and use of TM was manifested as part of their cultural identity. The findings have implications to improve the provision of culturally sensitive and responsive health services when caring for African migrant women.

The Pragmatic Association of Southeast Asian Nations Approach of Traditional Chinese Medicine Education in Indonesia: A Case Review.

Traditional Chinese Medicine (TCM) practice has been thriving for centuries throughout the world, but its educational system has not been standardized in many countries outside of China. The aim of this article is To share experiences in planning and executing TCM education adapted to Indonesian culture and conditions. TCM practice has thrived since centuries ago in Indonesia due to TCM's empirically proven effectiveness for maintaining health and wellness. However, formal bachelor's-degree education in TCM has just begun about a decade ago. The learning outcomes of TCM bachelor's-degree education in Indonesia and the Association of Southeast Asian Nations (ASEAN) at large differs from those of China mainly because of the nearly total integration of Western medicine modalities in China. The learning strategy of TCM education in Indonesia with a pragmatic acculturation approach has been effective for improving TCM acceptance, and has been beneficial in upgrading the social and academic status of Indonesian traditional health care based on ASEAN TCM standards.

The Association of Spanish Language Preference with Advance Directive Completion.

BACKGROUND/OBJECTIVES: Hispanics have lower advance directive (AD) completion than non-Hispanic Whites. Few studies have assessed the role of language preference in end-of-life planning. We investigated whether language preference and needing an interpreter affected AD completion among older adults in an integrated health system. DESIGN: Retrospective cohort investigation of electronic medical records. SETTING: Northern California integrated health system. PARTICIPANTS: A total of 620,948 Hispanic and non-Hispanic White patients, aged 55 years and older, between January 1, 2013, and December 31, 2017. MEASUREMENTS: Descriptive statistics and bivariate analysis were performed to compare AD completion among non-Hispanic Whites, Hispanics, and Hispanic subgroups by language preference (English speaking, Spanish speaking, and needed interpreter). We conducted multivariable logistic regression to determine the relationship between language preference and having an AD while controlling for demographic, clinical, and utilization factors. RESULTS: We found 20.3% of non-Hispanic Whites (n = 512,577) and 10.9% of Hispanics (n = 108,371) had completed an AD. Among Hispanics, after controlling for demographic, clinical, and utilization factors, compared with Spanish speakers requiring an interpreter, English speakers had nearly two-fold increased odds of completing an AD (adjusted odds ratio (aOR) = 2.6; 95% confidence interval (CI) = 2.4-2.9), whereas Spanish speakers not requiring an interpreter had 20% increased odds (aOR = 1.2; 95% CI = 1.1-1.3). Additional predictors of successful AD completion were being female, being older, having more comorbidities, having more hospital and emergency department visits, and having higher socioeconomic status. There were no differences associated with primary care provider characteristics. CONCLUSION: These findings indicate the need for a tailored outreach to Hispanics, particularly among those subgroups who require the need of an interpreter, to reduce AD completion disparities.

Self-rated Physical, Mental, Oral, and Cognitive Health in Older Korean Immigrants: The Role of Health Indicators and Sociocultural Factors.

Guided by the models of health assessment and social determinants of health, we examined predictors of self-rated physical, mental, oral, and cognitive health of older Korean immigrants. Data came from the Study of Older Korean Americans (SOKA; N = 2,061, Mean age = 73.2). Multivariate regression models of self-ratings of health were tested with health indicators (both domain-specific and other health indicators including chronic disease, functional disability, mental distress, problems with teeth or gums, and cognitive function) and sociocultural factors (acculturation, social network, and ethnic community social cohesion). For self-rated physical, mental, and oral health, indicators specific to the targeted domain played a primary role, with those of other health domains playing a secondary role. Acculturation and social network were significant predictors of all four measures. Findings highlight the importance of holistic health assessment that considers a wide range of health domains as well as sociocultural contexts.

Psychological morbidity among forcibly displaced children-a literature review.

In 2018, nearly 75 million people were displaced from their place of origin of which 20.4 million are considered as refugees. Children constitute over half of this population. A review of the currently available literature regarding the psychological impact of forced displacement on children was performed with the concept examined under three stages of flight: pre-migration, intra-migration and post-migration. The resilience of children despite adversities is explored. Post-traumatic stress disorder (PTSD), depression and anxiety are the most commonly studied effects of forced migration on children. Rates range from 20 to 52.7%, 23 to 44.1% and 38.3 to 69% respectively. PTSD is associated with pre-migration disturbances such as witnessing death or torture of relatives, assaults and separation from family. Intra-migration difficulties relate to the hazardous journey, length of detention, type of facility and failed asylum application. Post-migration difficulties highlighted are insecure asylum status, housing worries, multiple relocations and poor acculturation technique and are more related to depression and anxiety. Despite these challenges and the tremendous horror witnessed, the majority of children report good functionality in their host countries in the long-term. The purpose of this report is to provide an overview of the factors contributing to the manifestation of mental health issues in child refugees as well as to examine mechanisms which enhance successful resettling in the host society. Health and social care providers must understand the complex interplay between the damaging effects of displacement, and the innate protective factors that persecuted children possess. Management should involve a holistic approach that considers children, families and native communities.

Biculturalism in couple support for diabetes care in U.S.-born Chinese Americans.

Support in couples living with type 2 diabetes is associated with better health outcomes but support provision in collectivistic cultures has received limited research attention. To address this gap, we focused on couple dynamics and support in type 2 diabetes in U.S.-born Chinese Americans. Acculturation processes, particularly biculturalism, that is, the capacity to enact habits and practices from both the heritage and U.S. mainstream culture, were explored. Employing interpretive phenomenological methods, we conducted multiple narrative interviews with each of 15 couples regarding illness challenges and couple responses. Interviews were conducted in varied contexts, including with the couple, and in group interviews with people with diabetes or spouses. The unit of analysis was the couple, and narrative themes within the text were explored within the context of holistic couple summaries. We identified three key aspects of couple support: (i) Assisting with the diabetes treatment regimen; (ii) Moderating social and contextual factors that impede diabetes care; and (iii) Providing relational care and empathy for living with this challenging chronic condition. Support reflecting cultural maintenance of Chinese beliefs and practices include other directedness, family centeredness, and concerns for harmony and balance. Bicultural support patterns were also apparent in spousal communication that was both indirect and direct, and relationships marked by both interdependence and respect for independence or autonomy, reflecting both Chinese and U.S. cultural orientations, respectively. Working clinically with second and third generation Chinese immigrants requires clinical assessment of and responsiveness to couples' acculturation levels and bicultural skills.

HIV and religion in HIV-infected Asians and their families: A qualitative study.

AIM: This paper examines HIV-infected Asian Americans' experiences with religion throughout the course of their illness and their family relationships. BACKGROUND: As the number of Asians in the United States continues to grow, health professionals are beginning notice obvious gaps of knowledge in caring for this population, including HIV-infected individuals. Little is known about the impact of religion and faith on Asian Americans with HIV and their families. The study focuses on the participants' reported experiences to understand the variety of roles religion can play in the progression of a highly stigmatized chronic disease. METHODS: An in-depth interview was conducted in San Francisco and New York City with 30 HIV-infected Asians. Narrative samples and summarized responses was used to highlight themes that emerged from the participants' anecdotes. Interpretive content analysis was employed. RESULTS: These groups were categorized as (a) those who did not adhere to any religion, (b) those of tenuous religious faith with conflicted feelings, and (c) those of strong religious faith with congruent beliefs. Within these three groups, various themes were synthesized from the members' perceptions and past experiences with religion. Within each group, participants displayed various stages of reconciliation with their current faith-related beliefs and escape the family stress from their religion practices. Each participant's story shown the vast range of human understanding and faith experiences including self-actualization, acculturation, and depression. CONCLUSIONS: This research provides new insight on the challenge of managing HIV-infected patients in a culturally and religiously appropriate manner.

High overlap between traditional ecological knowledge and forest conservation found in the Bolivian Amazon.

It has been suggested that traditional ecological knowledge (TEK) may play a key role in forest conservation. However, empirical studies assessing to what extent TEK is associated with forest conservation compared with other variables are rare. Furthermore, to our knowledge, the spatial overlap of TEK and forest conservation has not been evaluated at fine scales. In this paper, we address both issues through a case study with Tsimane' Amerindians in the Bolivian Amazon. We sampled 624 households across 59 villages to estimate TEK and used remote sensing data to assess forest conservation. We ran statistical and spatial analyses to evaluate whether TEK was associated and spatially overlapped with forest conservation at the village level. We find that Tsimane' TEK is significantly and positively associated with forest conservation although acculturation variables bear stronger and negative associations with forest conservation. We also find a very significant spatial overlap between levels of Tsimane' TEK and forest conservation. We discuss the potential reasons underpinning our results, which provide insights that may be useful for informing policies in the realms of development, conservation, and climate. We posit that the protection of indigenous cultural systems is vital and urgent to create more effective policies in such realms.

Archaeogenomic analysis of the first steps of Neolithization in Anatolia and the Aegean.

The Neolithic transition in west Eurasia occurred in two main steps: the gradual development of sedentism and plant cultivation in the Near East and the subsequent spread of Neolithic cultures into the Aegean and across Europe after 7000 cal BCE. Here, we use published ancient genomes to investigate gene flow events in west Eurasia during the Neolithic transition. We confirm that the Early Neolithic central Anatolians in the ninth millennium BCE were probably descendants of local hunter-gatherers, rather than immigrants from the Levant or Iran. We further study the emergence of post-7000 cal BCE north Aegean Neolithic communities. Although Aegean farmers have frequently been assumed to be colonists originating from either central Anatolia or from the Levant, our findings raise alternative possibilities: north Aegean Neolithic populations may have been the product of multiple westward migrations, including south Anatolian emigrants, or they may have been descendants of local Aegean Mesolithic groups who adopted farming. These scenarios are consistent with the diversity of material cultures among Aegean Neolithic communities and the inheritance of local forager know-how. The demographic and cultural dynamics behind the earliest spread of Neolithic culture in the Aegean could therefore be distinct from the subsequent Neolithization of mainland Europe.

Healthcare needs and access in a sample of Chinese young adults in Vancouver, British Columbia: A qualitative analysis.

OBJECTIVES: Immigrants of Chinese ethnicity and young people (between 18 and 30 years of age) are known to access health services less frequently and may be at greater risk for experiencing unmet health needs. The purpose of this study was to examine the health beliefs, health behaviors, primary care access, and perceived unmet healthcare needs of Chinese young adults. METHODS: Semi-structured in-depth interviews were carried out with eight Chinese young adults in Vancouver, Canada. RESULTS: A content analysis revealed that these Chinese young adults experienced unmet healthcare needs, did not have a primary care provider, and did not access preventive services. Cultural factors such as strong family ties, filial piety, and the practice of Traditional Chinese Medicine influenced their health behaviors and healthcare access patterns. CONCLUSION: Chinese young adults share similar issues with other young adults in relation to not having a primary care provider and accessing preventive care but their health beliefs and practices make their needs for care unique from other young adults.

Acculturation and ethnomedicine: A regional comparison of medicinal plant knowledge among the Zoque of southern Mexico.

ETHNOPHARMACOLOGICAL RELEVANCE: In rural areas of Mexico the impact of modernization has changed healthcare and health seeking behaviour to varying degrees. This has rarely been accounted for when discussing and comparing medicinal floras. The ethnomedical system of the Zoque has never before been systematically studied. AIM OF THE STUDY: The objective of this study was to document medical practices and medicinal plant knowledge of the Zoque of Chiapas and Oaxaca, the latter being more strongly affected by acculturation. The medicinal floras are compared in order to detect similarities and differences and establishing links to the cultural transformation. METHODS: Research was carried out in a total of nine Zoque municipalities, attempting to adequately represent the cultural and ecological diversity of the Zoque territory. Standard anthropological and ethnobotanical methods were used for data collection. The recorded medicinal uses were classified into 17 disease categories according to emic medical concepts. In each category, the recorded taxa were rank-ordered based on number of use-reports and the informant consensus factor was calculated. The characteristics of the disease categories and the most salient taxa were compared across the two field sites. RESULTS AND DISCUSSION: A total of 6598 use-reports on 544 species have been collected. With the strongly acculturated Zoque of Oaxaca we have documented a considerably less extensive medicinal flora. The ethnopharmacopoeias of the two Zoque groups share 144 species. These species are of over-proportionate salience, accounting for two-thirds of the total use-reports. In both field sites gastrointestinal disorders are of particular importance, followed by women's diseases, respiratory diseases and musculoskeletal ailments. Children's and spiritual illnesses seem to have lost their importance in Oaxaca, as the underlying concepts are often considered backwards and superstitious. CONCLUSION: While it is difficult to establish a quantitative causal relation between acculturation and medicinal plant knowledge, in qualitative terms there are clear indicators for the changes acculturation has brought about in the medical system of the Zoque of Oaxaca. The results suggest the development of an increasingly homogenized pan-Mesoamerican medicinal flora.

Blood folate concentrations among women of childbearing age by race/ethnicity and acculturation, NHANES 2001-2010.

Hispanic women have higher rates of neural tube defects and report lower total folic acid intakes than non-Hispanic white (NHW) women. Total folic acid intake, which is associated with neural tube defect risk reduction, has been found to vary by acculturation factors (i.e. language preference, country of origin, or time spent in the United States) among Hispanic women. It is unknown whether this same association is present for blood folate status. The objective of this research was to assess the differences in serum and red blood cell (RBC) folate concentrations between NHW women and Mexican American (MA) women and among MA women by acculturation factors. Cross-sectional data from the 2001-2010 National Health and Nutrition Examination Survey (NHANES) were used to investigate how blood folate concentrations differ among NHW or MA women of childbearing age. The impact of folic acid supplement use on blood folate concentrations was also examined. MA women with lower acculturation factors had lower serum and RBC folate concentrations compared with NHW women and to their more acculturated MA counterparts. Consuming a folic acid supplement can minimize these disparities, but MA women, especially lower acculturated MA women, were less likely to report using supplements. Public health efforts to increase blood folate concentrations among MA women should consider acculturation factors when identifying appropriate interventions.

Change in waist circumference with longer time in the United States among Hispanic and Chinese immigrants: the modifying role of the neighborhood built environment.

PURPOSE: We examined whether living in neighborhoods supportive of healthier diets and more active lifestyles may buffer immigrants against the unhealthy weight gain that is purported to occur with longer length of US residence. METHODS: Neighborhood data referring to a 1-mile buffer around participants' baseline home addresses were linked to longitudinal data from 877 Hispanic and 684 Chinese immigrants aged 45 to 84 years in the Multi-Ethnic Study of Atherosclerosis. We used ethnicity-stratified linear mixed models to examine whether food and activity-based neighborhood measures (healthy food stores, walkability, and recreational facilities) were associated with change in waist circumference (WC) over a 9-year follow-up. RESULTS: Among Hispanics, living in neighborhoods with more resources for healthy food and recreational activity was related to lower baseline WC. However, there was no association with change in WC over time. Among Chinese, living in more walkable neighborhoods was associated with lower baseline WC and with slower increases in WC over time, especially among the most recent immigrant arrivals. CONCLUSIONS: Where immigrants reside may have implications for health patterns that emerge with longer time in the United States.

Family Efficacy as a Protective Factor Against Immigrant Adolescent Risky Behavior: A Literature Review.

Research suggests that family efficacy-defined as a family's beliefs in its capability to manage different situations in order to achieve a desired outcome-is linked to a decreased likelihood of adolescents to engage in risky health behaviors. It is not clear, however, if this is true for immigrant families when they are encountering with increased challenges in their host countries. To provide holistic nursing care to immigrant families, it is important to know the sources of family efficacy particularly for immigrant adolescents when they are developing health behavior. This integrative review examined existing literature to learn about the sources of family efficacy among immigrant adolescents and how different domain of family efficacy is related to risky behaviors. We examined 22 studies on the topics of immigration, adaptation, risky adolescent behavior, and family function. Findings showed that multidimensional sources of family efficacies (specifically those in the relational, pragmatic, and value-laden domains) exert significant positive effects on immigrant adolescents' health behaviors.

Evidence of traditional knowledge loss among a contemporary indigenous society.

As biological and linguistic diversity, the world's cultural diversity is on decline. However, to date there are no estimates of the rate at which the specific cultural traits of a group disappear, mainly because we lack empirical data to assess how the cultural traits of a given population change over time. Here we estimate changes in cultural traits associated to the traditional knowledge of wild plant uses among an Amazonian indigenous society. We collected data among 1151 Tsimane' Amerindians at two periods of time. Results show that between 2000 and 2009, Tsimane' adults experienced a net decrease in the report of plant uses ranging from 9% (for the female subsample) to 26% (for the subsample of people living close to towns), equivalent to a 1 to 3 % per year. Results from a Monte Carlo simulation show that the observed changes were not the result of randomness. Changes were more acute for men than for women and for informants living in villages close to market towns than for informants settled in remote villages. The Tsimane' could be abandoning their traditional knowledge as they perceive that this form of knowledge do not equip them well to deal with the new socio-economic and cultural conditions they face nowadays.

Secular trends on traditional ecological knowledge: An analysis of different domains of knowledge among Tsimane' men.

Empirical research provides contradictory evidence of the loss of traditional ecological knowledge across societies. Researchers have argued that culture, methodological differences, and site-specific conditions are responsible for such contradictory evidences. We advance and test a third explanation: the adaptive nature of traditional ecological knowledge systems. Specifically, we test whether different domains of traditional ecological knowledge experience different secular changes and analyze trends in the context of other changes in livelihoods. We use data collected among 651 Tsimane' men (Bolivian Amazon). Our findings indicate that different domains of knowledge follow different secular trends. Among the domains of knowledge analyzed, medicinal and wild edible knowledge appear as the most vulnerable; canoe building and firewood knowledge seem to remain constant across generations; whereas house building knowledge seems to experience a slight secular increase. Our analysis reflects on the adaptive nature of traditional ecological knowledge, highlighting how changes in this knowledge system respond to the particular needs of a society in a given point of time.
