Medicinal plants of the upper Aswa River catchment of northern Uganda - a cultural crossroads

BACKGROUND

This paper presents a comparative inventory of medicinal plant taxa and their uses by smallholder farming communities of four cultures in the Aswa River catchment of northern Uganda, situated in the eastern Sudanian savanna parkland ecotype of sub-Saharan Africa. The purpose of the study was to document the ethnobotanical use of medicinal plants by the Lango, Acholi, Teso (Atesot) and Ethur (jo Abwor), in an historical moment before civil conflict and mass displacement of the respondent communities disrupted the inter-generational transmission of traditional technical knowledge within the study area.

METHODS

Following community consultations in four districts of northern Uganda during 1999-2000, interviews were conducted with holders of specialist knowledge on plants used as medicine on basis of a plant specimen allocated a voucher number and identified by the national herbarium. Use reports reflecting specific medicinal applications were compiled in aggregate to obtain a Relative Importance Index ranking. The commonality of medicinal taxa cited between each cultural interface was assessed by the Jaccard Index of Similarity, and the similarity of specific medicinal usage by taxon using Rahman's Similarity Index.

RESULTS

The data collected from 112 respondents comprise 280 medicinal use reports describing 263 applications for 62 medical conditions, citing 108 taxa from 44 botanical families of which Fabaceae comprised 20% of all use reports. No earlier mention could be found to corroborate 72 use reports (27% of the total), representing medicinal indications as yet undocumented, and potentially worthy of investigation. The RI values ranged between 15 and 94%, with 13 taxa having RI values above 50%. The JI ratios indicate the highest degree of similarity in the plant taxa used as medicine (21%) between the Lango and Teso cultures who share a common origin; however, Rahman's Similarity Index indicates the highest similarity of specific medicinal usage by taxon between the Lango and Acholi, who share a common language group through cultural assimilation over time.

CONCLUSIONS

As a comparative study, the results imply that cultural exchange and assimilation may be a greater driver of inter-cultural similarity of ethnopharmacological use of a given taxon, as compared to shared historical origins.

Anxiety about aging, resilience and health Status among Chinese older adults: Findings from Honolulu and Wuhan

A growing body of literature found that anxiety about aging is related to health and well-being of older adults. However, very few studies have been conducted on Chinese older adults residing in different countries and examined the role of resilience. Using the Pearlin's Stress Process Model, this study aims to fill in this gap by examining the relationship between anxiety about aging as the stressor and health status among Chinese older adults living in Honolulu, the United States (N = 292) and Wuhan, China (N = 532). The survey data were collected through June 2017 to September 2018, using snowball and convenience sampling strategy. The moderating role of resilience on the focal relationship is also explored. Results showed that for both samples, the negative relationship between anxiety about aging and self-rated health was significantly moderated by resilience (18 % and 13 %, respectively), implying the stress-buffering role of resilience. Although both mean levels of resilience and anxiety about aging were lower for the Honolulu sample, the moderating effect appeared to be stronger, implying that older adults in the Honolulu sample might rely more on psychological resources such as resilience in coping with stressors, compared with their counterparts in Wuhan. However, the moderating effect of resilience did not work for the association between anxiety about aging and number of chronic conditions for both samples. Our findings suggest that future research needs to take into account both social and psychological resources when examining anxiety about aging and health status among Chinese older adults residing in different cultural contexts.

Childbirth preferences and related fears - comparison between Norway and Israel

Background

Fear of childbirth (FOC) could have significant impact on women’s childbearing choices and experience. Culture affects the way women conceptualize childbirth, influencing the fears and expectations they may hold in relation to it. In the current study, we examined differences in childbirth preferences of cesarean section and use of epidural analgesia between Norwegian and Israeli pregnant women. Later, we used the Norwegian six-factor solution of the widely-used Wijma Delivery Expectancy Questionnaire (W-DEQ-A) to compare levels of the different FOC factors. Finally, we investigated differences in the associations between FOC and childbirth preferences between the two countries.

Methods

Secondary analysis of two large surveys. Women from Israel (n = 490) and Norway (n = 2918) were recruited during prenatal check-ups in community clinics and a university hospital. At around 32 weeks of gestation, all participants filled out questionnaires, including the W-DEQ-A. Statistical analysis included exploratory factor analysis, confirmatory factor analysis, M/ANOVA, Spearman’s Rho and Fisher’s Z tests for the significance of the difference between independent correlations.

Results

The Norwegian six-factor solution of the W-DEQ fit well with the Israeli data. Norwegian women were more concerned about loneliness, feeling less self-efficacy, negatively appraising birth, and lacking positive anticipation. Israeli women were more concerned about negative outcomes for the child and experienced greater general fear and fear of pain. Norwegian women preferred more cesarean sections compared to Israeli women, who preferred more epidural use than Norwegians. FOC factors were more strongly related to childbirth preferences among Norwegians.

Conclusions

Cultural differences between Israel and Norway are reflected by the differences seen in the levels of fear reported across the six factors. In Israel, birth culture is very medicalized, motherhood is highly revered, and there is an emphasis on having “perfect babies”. In contrast, Norwegian women have fewer children, and birth is considered more natural. This could explain why Israeli women were more concerned that their child might be harmed during birth, while Norwegian women were more concerned with the physical and emotional expectations of birth.

Comparing health-related quality of life of Dutch and Chinese patients with traumatic brain injury: do cultural differences play a role?

BACKGROUND

There is growing interest in health related quality of life (HRQoL) as an outcome measure in international trials. However, there might be differences in the conceptualization of HRQoL across different socio-cultural groups. The objectives of current study were: (I) to compare HRQoL, measured with the short form (SF)-36 of Dutch and Chinese traumatic brain injury (TBI) patients 1 year after injury and; (II) to assess whether differences in SF-36 profiles could be explained by cultural differences in HRQoL conceptualization. TBI patients are of particular interest because this is an important cause of diverse impairments and disabilities in functional, physical, emotional, cognitive, and social domains that may drastically reduce HRQoL.

METHODS

A prospective cohort study on adult TBI patients in the Netherlands (RUBICS) and a retrospective cohort study in China were used to compare HRQoL 1 year post-injury. Differences on subscales were assessed with the Mann-Whitney U-test. The internal consistency, interscale correlations, item-internal consistency and item-discriminate validity of Dutch and Chinese SF-36 profiles were examined. Confirmatory factor analysis was performed to assess whether Dutch and Chinese data fitted the SF-36 two factor-model (physical and mental construct).

RESULTS

Four hundred forty seven Dutch and 173 Chinese TBI patients were included. Dutch patients obtained significantly higher scores on role limitations due to emotional problems (p < .001) and general health (p < .001), while Chinese patients obtained significantly higher scores on physical functioning (p < .001) and bodily pain (p = .001). Scores on these subscales were not explained by cultural differences in conceptualization, since item- and scale statistics were all sufficient. However, differences among Dutch and Chinese patients were found in the conceptualization of the domains vitality, mental health and social functioning.

CONCLUSIONS

One year after TBI, Dutch and Chinese patients reported a different pattern of HRQoL. Further, there might be cultural differences in the conceptualization of some of the SF-36 subscales, which has implications for outcome evaluation in multi-national trials.
