The Burden of Elders: Anxiety, Depression, and Personal Networks in Two African Slums

ABSTRACT

Although anxiety and depression have been central topics for scholars and clinicians in the United States, few studies have examined their correlates in sub-Saharan Africa and none have examined large urban slums. Using face-to-face interviews in two African cities, we analyze self-reported symptoms of anxiety and depression in a community-based sample (n = 495). Ordinary least squares regression was used to analyze a variety of demographic and social predictors including sex, child-rearing, marital status, education, income, age, and neighborhood for residents of Agbogbloshie (Accra, Ghana) and Kangemi (Nairobi, Kenya). Controlling for other factors, two personal network dimensions were significant. Total network size is positively associated with symptoms of anxiety and depression in Kenya but not in Ghana. However, one factor was predictive of symptoms of anxiety and depression in both locations: the reported percentage of ties with older persons. Higher levels of anxiety and depression are associated with a larger share of older individuals in one's personal network.

Validating dental age estimation in Kenyan black children and adolescents using the Willems method

PURPOSE

This study aimed to validate the Willems Belgian Caucasian (Willems BC) age estimation model in a Kenyan sample, to develop and validate a Kenyan-specific (Willems KB) age estimation model and to compare the age prediction performances of both models.

METHODS

Panoramic radiographs of 1038 (523 female, 515 male) Kenyan children without missing permanent teeth and without all permanent teeth fully developed (except third molars) were retrospectively selected. Tooth development of the seven lower-left permanent teeth was staged according to Demirjian et al. The Willems BC model, performed on a Belgian Caucasian sample and a constructed Kenyan-specific model (Willems KB) were validated on the Kenyan sample. Their age prediction performances were quantified and compared using the mean error (ME), mean absolute error (MAE) and root-mean-square error (RMSE).

RESULTS

The ME with Willems BC method equalled zero. Hence, there was no systematic under- or overestimation of the age. For males and females separately, the ME with Willems BC was significantly different from zero, but negligible in magnitude (-0.04 and 0.04, respectively). Willems KB was found not to outperform Willems BC, since the MAE and RMSE were comparable (0.98 vs 0.97 and 1.31 vs 1.29, respectively). Although Willems BC resulted in a higher percentage of subjects with predicted age within a one-year difference of the true age (63.3% vs 60.4%, p=0.018), this cannot be considered as clinically relevant.

CONCLUSION

There is no reason to use a country-specific (Willems KB) model in children from Kenya instead of the original Willems (BC) model.

A multiple baseline study of a brief alcohol reduction and family engagement intervention for fathers in Kenya

OBJECTIVE

To evaluate a lay provider-delivered, brief intervention to reduce problem drinking and related family consequences among men in Kenya. The 5-session intervention combines behavioral activation (BA) and motivational interviewing (MI). It integrates family-related material explicitly and addresses central cultural factors through gender transformative strategies.

METHOD

A nonconcurrent multiple-baseline design was used. We initiated treatment with 9 men ages 30 to 48 who were fathers and screened positive for problem drinking; the median Alcohol Use Identification Test score was 17 (harmful range). Participants were randomized to staggered start dates. We measured the primary outcome of weekly alcohol consumption 4 weeks before treatment, during treatment, and 4 weeks posttreatment using the Timeline Followback measure. Secondary outcomes were assessed using a pre-post assessment (1-month) of men's depression symptoms, drinking- and family-related problem behavior, involvement with child, time with family, family functioning, relationship quality (child and partner), and harsh treatment of child and partner. Men, partners, and children (ages 8-17) reported on family outcomes.

RESULTS

Eight men completed treatment. Mixed-effects hurdle model analysis showed that alcohol use, both number of days drinking and amount consumed, significantly decreased during and after treatment. Odds of not drinking were 5.1 times higher posttreatment (95% CI [3.3, 7.9]). When men did drink posttreatment, they drank 50% less (95% CI [0.39, 0.65]). Wilcoxon signed-ranks test demonstrated pre-post improvements in depression symptoms and family related outcomes.

CONCLUSION

Results provide preliminary evidence that a BA-MI intervention developed for lay providers may reduce alcohol use and improve family outcomes among men in Kenya. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Intimate partner violence: A key correlate of women's physical and mental health in informal settlements in Nairobi, Kenya

Globally, one billion people live in informal settlements, and that number is expected to triple by 2050. Studies suggests that health in informal settlements is a serious and growing concern, yet there is a paucity of research focused on health outcomes and the correlates of health in these settlements. Studies cite individual, environmental and social correlates to health in informal settlements, but they often lack empirical evidence. In particular, research suggests that high rates of violence against women (VAW) in informal settlements may be associated with detrimental effects on women's health, but few studies have investigated this link. The purpose of this study was to fill this gap by empirically exploring associations between women's experiences of intimate partner violence (IPV) and their physical and mental health. Data for this study were collected in August 2018 in Mathare Valley Informal Settlement in Nairobi, Kenya. A total of 550 randomly-selected women participated in surveys; however, analyses for this study were run on a subpopulation of the women (n = 361). Multivariate logistic regressions were used to investigate the link between psychological, sexual, and emotional IPV and women's mental and physical health. Results suggest that while some socioeconomic, demographic, and environmental variables were significantly associated with women's mental and physical health outcomes, all types of IPV emerged key correlates in this context. In particular, women's experiences of IPV were associated with lower odds of normal-high physical health component scores (based on SF-36); higher odds of gynecological and reproductive health issues, psychological distress (based on K-10), depression, suicidality, and substance use. Findings from this study suggest that policies and interventions focused on prevention and response to VAW in informal settlements may make critical contributions to improving health for women in these rapidly growing settlements.

Human large-scale cooperation as a product of competition between cultural groups

A fundamental puzzle of human evolution is how we evolved to cooperate with genetically unrelated strangers in transient interactions. Group-level selection on culturally differentiated populations is one proposed explanation. We evaluate a central untested prediction of Cultural Group Selection theory, by assessing whether readiness to cooperate between individuals from different groups corresponds to the degree of cultural similarity between those groups. We documented the normative beliefs and cooperative dispositions of 759 individuals spanning nine clans nested within four pastoral ethnic groups of Kenya-the Turkana, Samburu, Rendille and Borana. We find that cooperation between groups is predicted by how culturally similar they are, suggesting that norms of cooperation in these societies have evolved under the influence of group-level selection on cultural variation. Such selection acting over human evolutionary history may explain why we cooperate readily with unrelated and unfamiliar individuals, and why humans' unprecedented cooperative flexibility is nevertheless culturally parochial.

Parenting, culture, and the development of externalizing behaviors from age 7 to 14 in nine countries

Using multilevel models, we examined mother-, father-, and child-reported (N = 1,336 families) externalizing behavior problem trajectories from age 7 to 14 in nine countries (China, Colombia, Italy, Jordan, Kenya, the Philippines, Sweden, Thailand, and the United States). The intercept and slope of children's externalizing behavior trajectories varied both across individuals within culture and across cultures, and the variance was larger at the individual level than at the culture level. Mothers' and children's endorsement of aggression as well as mothers' authoritarian attitudes predicted higher age 8 intercepts of child externalizing behaviors. Furthermore, prediction from individual-level endorsement of aggression and authoritarian attitudes to more child externalizing behaviors was augmented by prediction from cultural-level endorsement of aggression and authoritarian attitudes, respectively. Cultures in which father-reported endorsement of aggression was higher and both mother- and father-reported authoritarian attitudes were higher also reported more child externalizing behavior problems at age 8. Among fathers, greater attributions regarding uncontrollable success in caregiving situations were associated with steeper declines in externalizing over time. Understanding cultural-level as well as individual-level correlates of children's externalizing behavior offers potential insights into prevention and intervention efforts that can be more effectively targeted at individual children and parents as well as targeted at changing cultural norms that increase the risk of children's and adolescents' externalizing behavior.

Distribution of Orofacial Clefts and Frequent Occurrence of an Unusual Cleft Variant in the Rift Valley of Kenya

Objective:

To investigate the pattern and distribution of nonsyndromic orofacial clefts among patients in the Rift Valley region of northwestern Kenya.

Methods:

Subjects were categorized anatomically for occurrence of an atypical cleft lip variant (ACL), typical cleft lip (CL), cleft lip and palate (CLP), or cleft palate (CP), and family history of orofacial clefts. Tribal ethnicity data were obtained from both cleft and noncleft clinic attendees.

Results:

There were 194 patients with CL (52.7%), 153 with CLP (41.6%), and 21 with CP (5.7%). CL constitutes a greater fraction of orofacial clefts in the Rift Valley region than reported elsewhere in Africa, principally due to frequent occurrence of ACL (52.5% of all CL). Among noncleft clinic attendees there was a lower fraction of Bantu and larger fraction of Nilotic-Paranilotic tribal ethnicity than in Kenya overall. In contrast, among patients with orofacial clefts there was significant underrepresentation of Bantu and overrepresentation of Nilotic-Paranilotic tribes, particularly Kalenjin. Patients of Kalenjin origin had a much higher rate of positive family history of orofacial clefts than Bantu patients.

Conclusions:

There is an unusual anatomic distribution of orofacial clefts in the Kenya Rift Valley, with frequent occurrence of an atypical CL variant. Our findings indicate that Bantu tribes have lower risk of orofacial clefts than Nilotic-Paranilotic tribes, possibly due to inherited genetic differences, perhaps accounting for the relatively low prevalence of orofacial clefts through much of Africa.

Sanitation practices and perceptions in Kakuma refugee camp, Kenya: Comparing the status quo with a novel service-based approach

Globally, an estimated 2.5 billion people lack access to improved sanitation. Unimproved sanitation increases the risk of morbidity and mortality, especially in protracted refugee situations where sanitation is based on pit latrine use. Once the pit is full, waste remains in the pit, necessitating the construction of a new latrine, straining available land and funding resources. A viable, sustainable solution is needed. This study used qualitative and quantitative methods to design, implement, and pilot a novel sanitation system in Kakuma refugee camp, Kenya. An initial round of 12 pre-implementation focus group discussions (FGDs) were conducted with Dinka and Somali residents to understand sanitation practices, perceptions, and needs. FGDs and a supplementary pre-implementation survey informed the development of an innovative sanitation management system that incorporated the provision of urine and liquid-diverting toilets, which separate urine and fecal waste, and a service-based sanitation system that included weekly waste collection. The new system was implemented on a pilot scale for 6 weeks. During the implementation, bi-weekly surveys were administered in each study household to monitor user perceptions and challenges. At the end of the pilot, the sanitation system was assessed using a second round of four post-implementation FGDs. Those who piloted the new sanitation system reported high levels of user satisfaction. Reported benefits included odor reduction, insect/pest reduction, the sitting design, the appropriateness for special populations, and waste collection. However, urine and liquid diversion presented a challenge for users who perform anal washing and for women who had experienced female genital mutilation. Refugee populations are often culturally and ethnically diverse. Using residents' input to inform the development of sanitation solutions can increase user acceptability and provide opportunities to improve sanitation system designs based on specific needs.

Narrating sexual identities in Kenya: "Choice," value, and visibility

This article examines the discursive construction of female same-sex sexual identities in Nairobi. We identify the discursive forces of "choice," devaluation, and invisibility as influential within Kenyan media representations of lesbian, gay, bisexual, transgender, and intersex citizens. Using creative focus groups and participant observation, we demonstrate how same-sex attracted women in Nairobi resist and rearticulate these discursive forces to assert their identity and agency as individuals and as a queer community.

Explanatory model of psychosis: impact on perception of self-stigma by patients in three sub-saharan African cities

BACKGROUND

Most cultures in sub-Saharan Africa subscribe to the belief that the root cause of psychosis is supernatural. Individuals in the community who hold a religiomagical explanatory model of causation have been shown to exhibit more stigmatizing attitudes towards people with psychosis. Self-stigma among individuals with psychosis is less frequently studied.

METHOD

We used a mixed-method approach, consisting of key informant's interviews to elicit information on explanatory models of causation of psychosis and questionnaire assessment of internalized stigma with an adapted version of the Scale for Internalized Stigma of Mental Illness. Twenty-four, 31, and 30 subjects with recent experience of utilizing the service of traditional or faith healers for severe mental disorders in Ibadan (Nigeria), Kumasi (Ghana), and Nairobi (Kenya), respectively, were interviewed.

RESULTS

About 44 % (42.1 %) of the Nigerian respondents had a high (severe) level of self-stigma with the respective proportions among Ghanaian and Kenyan respondents being 20.7 and 37.5 %. Compared with 4 out of a total of 12 respondents (33.3 %) who reported low self-stigma reported supernatural attribution, 14 out of 20 respondents (70 %) with the highest level of self-stigma reported supernatural attribution across the three sites. When low scorers ascribed supernatural causation, it was often with a religious focus.

CONCLUSION

There is a greater tendency for persons with high levels of self-stigma than those with low levels to ascribe supernatural attribution to their experience of a severe mental health condition.

Stigmatizing attitudes toward mental illness among primary school children in Kenya

BACKGROUND

Literature describing stigmatizing attitudes towards people with mental illness by children in the developing world is lacking. Children's mental health issues in the Kenyan context are especially pertinent due to the increased likelihood of exposure to risk factors and the high prevalence of mental disorders. The objective of the current study was to examine socio-demographic factors associated with the endorsement of stigmatizing attitudes towards people with mental illness among Kenyan school children.

METHODS

We analyzed cross-sectional survey data from 4585 primary school-aged children in standards one through seven in the Eastern Province of Kenya. We examined relationships between the endorsement of stigmatizing attitudes and age, gender, district, religion, being in the standard appropriate for one's age, and parental employment status.

RESULTS

Stigma scores decreased with increasing age (β = -0.83; 95 % CI = -0.99 to -0.67). Boys had higher stigma scores compared to girls (β = 1.55; 95 % CI = 0.86-2.24). Students from the rural district had higher average stigma scores as compared to those from the peri-urban district (β = 1.14; 95 % CI = 0.44-1.84). Students who were not in the standard appropriate for their age had lower stigma scores than those who were in the standard typical for their age (β = -1.60; 95 % CI = -2.43 to -0.77).

CONCLUSIONS

Stigmatizing attitudes toward the mentally ill exist among primary school children in Kenya; thus, anti-stigma interventions are needed, and our findings highlight particular subgroups that could be targeted.

Rethinking peer support for diabetes in Vancouver's South-Asian community: a feasibility study

AIM

To examine the feasibility and potential health impact of a diabetes self-management education and support intervention involving peer support on glycaemic control and diabetes distress.

METHODS

A total of 41 South-Asian adults with Type 2 diabetes were recruited for a 24-week diabetes self-management education and support pilot intervention involving peer support. The intervention consisted of six weekly education sessions co-facilitated by a certified diabetes educator and two peer leaders, followed by 18 weekly support sessions facilitated by two peer leaders. Education sessions were guided entirely by participants' self-management questions and also emphasized goal setting and action planning. Support sessions were based on empowerment principles and participants discussed self-management challenges, shared emotions, asked self-management questions, problem-solved in a group, set goals, and developed and evaluated action plans. Feasibility outcomes included recruitment and retention. Primary health-related outcomes included HbA1c levels and diabetes distress (measured at baseline, 6 and 24 weeks). Programme satisfaction was also assessed.

RESULTS

Pre-established criteria for recruitment and retention were met. Paired t-tests showed no changes in HbA1c and diabetes distress at 6 weeks. At 24 weeks, HbA1c levels deteriorated [54 mmol/mol (7.1%) vs 61 mmol/mol (7.7%)] while diabetes distress scores improved (2.0 vs 1.7).

CONCLUSIONS

Although feasible, findings suggest this peer-support model may have a positive impact on diabetes distress, but not on HbA1c levels. Culturally responsive modifications (e.g. intervention location) to the pilot model are needed and could lead to more favourable health outcomes for this community. Such a re-designed peer-support model will require further investigation.

Male circumcision and sexual risk behaviors may contribute to considerable ethnic disparities in HIV prevalence in Kenya: an ecological analysis

BACKGROUND

HIV prevalence varies between 0.8 and 20.2% in Kenya's various ethnic groups. The reasons underlying these variations have not been evaluated before.

METHODS

We used data from seven national surveys spanning the period 1989 to 2008 to compare the prevalence of a range of risk factors in Kenya's ethnic groups. Spearman's and linear regression were used to assess the relationship between HIV prevalence and each variable by ethnic group.

RESULTS

The ethnic groups exhibited significant differences in a number of HIV related risk factors. Although the highest HIV prevalence group (the Luo) had the highest rates of HIV testing (Men 2008 survey: 56.8%, 95% CI 51.0-62.5%) and condom usage at last sex (Men 2008∶28.6%, 95% CI 19.6-37.6%), they had the lowest prevalence of circumcision (20.9%, 95% CI 15.9-26.0) the highest prevalence of sex with a non-married, non-cohabiting partner (Men: 40.2%, 95% CI 33.2-47.1%) and pre-marital sex (Men 2008∶73.9%, 95% CI 67.5-80.3%) and the youngest mean age of debut for women (1989 SURVEY: 15.7 years old, 95% CI 15.2-16.2). At a provincial level there was an association between the prevalence of HIV and male concurrency (Spearman's rho = 0.79, P = 0.04). Ethnic groups with higher HIV prevalence were more likely to report condom use (Men 2008 survey: R2 = 0.62, P = 0.01) and having been for HIV testing (Men 2008 survey: R2 = 0.47, P = 0.04).

CONCLUSION

In addition to differences in male circumcision prevalence, variation in sexual behavior may contribute to the large variations in HIV prevalence in Kenya's ethnic groups. To complement the prevention benefits of the medical male circumcision roll-out in several parts of Kenya, interventions to reduce risky sexual behavior should continue to be promoted.

Conceptualizations of heterosexual anal sex and HIV risk in five East African communities

Heterosexual anal sex is underresearched and little understood, particularly in the African context. Existing prevalence data indicate that heterosexual anal sex is a widespread practice, yet little is known about the way in which it is conceptualized and understood. Describing findings from qualitative research conducted in Kenya, Tanzania, and Uganda, we shed light on conceptualizations of heterosexual anal sex and its relation to human immunodeficiency virus (HIV). These findings suggest that penile-anal sex is practiced by men and women in Africa for a range of reasons, including virginity maintenance, contraception, fulfillment of male pleasure, relationship security, menstruation, in the presence of vaginal complications, financial gain, fidelity, and prestige. Despite anal sex being the most efficient way to transmit HIV sexually, there is widespread lack of knowledge about its risks. These findings describe the ways in which anal sex is conceptualized in five East African communities, highlighting how penile-anal intercourse is often not considered "sex" and how the omission of anal sex in safe-sex messaging is interpreted as meaning that anal sex is safe. In light of its frequency and risks, greater attention must be paid to heterosexual anal sex in Africa to ensure a comprehensive approach to HIV prevention.

Aerobic Capacity, Activity Levels and Daily Energy Expenditure in Male and Female Adolescents of the Kenyan Nandi Sub-Group

The relative importance of genetic and socio-cultural influences contributing to the success of east Africans in endurance athletics remains unknown in part because the pre-training phenotype of this population remains incompletely assessed. Here cardiopulmonary fitness, physical activity levels, distance travelled to school and daily energy expenditure in 15 habitually active male (13.9±1.6 years) and 15 habitually active female (13.9±1.2) adolescents from a rural Nandi primary school are assessed. Aerobic capacity ([Formula: see text]) was evaluated during two maximal discontinuous incremental exercise tests; physical activity using accelerometry combined with a global positioning system; and energy expenditure using the doubly labelled water method. The [Formula: see text] of the male and female adolescents were 73.9±5.7 ml(.) kg(-1.) min(-1) and 61.5±6.3 ml(.) kg(-1.) min(-1), respectively. Total time spent in sedentary, light, moderate and vigorous physical activities per day was 406±63 min (50% of total monitored time), 244±56 min (30%), 75±18 min (9%) and 82±30 min (10%). Average total daily distance travelled to and from school was 7.5±3.0 km (0.8-13.4 km). Mean daily energy expenditure, activity-induced energy expenditure and physical activity level was 12.2±3.4 MJ(.) day(-1), 5.4±3.0 MJ(.) day(-1) and 2.2±0.6. 70.6% of the variation in [Formula: see text] was explained by sex (partial R(2) = 54.7%) and body mass index (partial R(2) = 15.9%). Energy expenditure and physical activity variables did not predict variation in [Formula: see text] once sex had been accounted for. The highly active and energy-demanding lifestyle of rural Kenyan adolescents may account for their exceptional aerobic fitness and collectively prime them for later training and athletic success.

An elective pharmaceutical care course to prepare students for an advanced pharmacy practice experience in Kenya

OBJECTIVE. To develop a prerequisite elective course to prepare students for an advanced pharmacy practice experience (APPE) in Kenya. DESIGN. The course addressed Kenyan culture, travel preparation, patient care, and disease-state management. Instructional formats used were small-group discussions and lectures, including some Web-based presentations by Kenyan pharmacists on disease states commonly treated in Kenya. Cultural activities include instruction in conversational and medical Kiswahili and reading of a novel related to global health programs. ASSESSMENT. Student performance was assessed using written care plans, quizzes, reflection papers, a formulary management exercise, and pre- and post-course assessments. Student feedback on course evaluations indicated that the course was well received and students felt prepared for the APPE. CONCLUSION. This course offered a unique opportunity for students to learn about pharmacy practice in global health and to apply previously acquired skills in a resource-constrained international setting. It prepares students to actively participate in clinical care activities during an international APPE.

Isolated in a technologically connected world?: Changes in the core professional ties of female researchers in Ghana, Kenya, and Kerala, India

Using panel data gathered across two waves (2001 and 2005) from researchers in Ghana, Kenya, and Kerala, India, we examine three questions: (1) To what extent do gender differences exist in the core professional networks of scientists in low-income areas? (2) How do gender differences shift over time? (3) Does use of information and communication technologies (ICTs) mediate the relationship between gender and core network composition? Our results indicate that over a period marked by dramatic increases in access to and use of various ICTs, the composition and size of female researchers core professional ties have either not changed significantly or have changed in an unexpected direction. Indeed, the size of women's ties are retracting over time rather than expanding.

Ethnographic empathy and the social context of rights: “rescuing” Maasai girls from early marriage

Esther is one of many young Maasai girls in Kenya "rescued" from early marriage. Her story is conventionally portrayed (trans)nationally and locally as a struggle between conservative pastoral patriarchs and the individual right of young girls to an education. I offer an ethnographic contextualization of the underlying factors giving rise to practices of early marriage, among the Maasai in Enkop, highlighting the contemporary predicaments of pastoralism in the face of population growth, climactic instability, and land-tenure reform and the insecurities and challenges around formal education. Through the intimate portrayal of Esther's case, early marriage is situated not as a relic of tradition and malicious patriarchy but, rather, as a contemporary adaptation to livelihood insecurity. I illustrate how prevailing concepts of "tradition," "culture," "victimhood," and "collective rights" in human rights theory obscure important structural factors that give rise to early marriage and deflect attention from effective policy initiatives.

The association between parental warmth and control in thirteen cultural groups

The goal of the current study was to investigate potential cross-cultural differences in the covariation between two of the major dimensions of parenting behavior: control and warmth. Participants included 1,421 (51% female) 7- to 10-year-old (M = 8.29, SD = .67 years) children and their mothers and fathers representing 13 cultural groups in nine countries in Africa, Asia, Europe, the Middle East, and North and South America. Children and parents completed questionnaires and interviews regarding mother and father control and warmth. Greater warmth was associated with more control, but this association varied widely between cultural groups.

Infant oral mutilation: a New Zealand case series

Infant oral mutilation is a practice performed by traditional healers in many Eastern African countries. The sequelae of this practice have been recognised and reported on in many developed countries due to the migration of populations, customs and beliefs. This article describes three cases of infant oral mutilation that have been diagnosed in the Dental Department at Hutt Hospital, Lower Hutt.

Spring cleaning: rural water impacts, valuation, and property rights institutions

Using a randomized evaluation in Kenya, we measure health impacts of spring protection, an investment that improves source water quality. We also estimate households' valuation of spring protection and simulate the welfare impacts of alternatives to the current system of common property rights in water, which limits incentives for private investment. Spring infrastructure investments reduce fecal contamination by 66%, but household water quality improves less, due to recontamination. Child diarrhea falls by one quarter. Travel-cost based revealed preference estimates of households' valuations are much smaller than both stated preference valuations and health planners' valuations, and are consistent with models in which the demand for health is highly income elastic. We estimate that private property norms would generate little additional investment while imposing large static costs due to above-marginal-cost pricing, private property would function better at higher income levels or under water scarcity, and alternative institutions could yield Pareto improvements.

Bridges to nowhere: hosts, migrants, and the chimera of social capital in three African cities

Interest in migrant social networks and social capital has grown substantially over the past several decades. The relationship between “host” and “migrant” communities remains central to these scholarly debates. Recently urbanized cities in Africa, which include large numbers of “native-born” or internal migrants, challenge basic presumptions about host/migrant distinctions informing many of these discussions. Using comparable survey data from Johannesburg, Maputo, and Nairobi, we examine 1) the nature of social connectedness in terms of residence and nativity characteristics; and 2) the relationship between residence and nativity characteristics and three measures of trust within and across communities. Our findings suggest that the host/migrant distinction may not be particularly revealing in African cities where domestic mobility, social fragmentation and the absence of bridging institutions result in relatively low levels of trust both within and across communities. These findings underscore the need for new concepts to study “communities of strangers” and how people strategize their social mobility in urban contexts.

Localizing HIV/AIDS discourse in a rural Kenyan community

This paper examines the effectiveness of multimodal texts used in HIV/AIDS campaigns in rural western Kenya using multimodal discourse analysis (Kress and Van Leeuwen, 2006; Martin and Rose, 2004). Twenty HIV/AIDS documents (posters, billboards and brochures) are analysed together with interview data (20 unstructured one-on-one interviews and six focus groups) from the target group to explore the effectiveness of the multimodal texts in engaging the target rural audience in meaningful interaction towards behavioural change. It is concluded that in some cases the HIV/AIDS messages are misinterpreted or lost as the multimodal texts used are unfamiliar and contradictory to the everyday life experiences of the rural folk. The paper suggests localization of HIV/AIDS discourse through use of local modes of communication and resources.

Bad blood: poverty, psychopathy and the politics of transgression in Kenya Colony, 1939-59

This article examines the inter-relationship between psychiatry and sex, both fertile fields within the recent historiography of colonialism and empire. Using a series of case files pertaining to European patients admitted to the Mathari Mental Hospital in Nairobi during the 1940s and 1950s, this article shows how sexual transgression among colonial Europeans precipitated, and was combined with, mental distress. Considering psychiatric treatment as a form of social control, the article investigates a number of cases in which a European patient had been perceived to have transgressed the normative sexual behaviour codes of settler society in Kenya. What these files suggest is that transgressive sexuality in Kenya was itself framed by indices, as insistent as they were uncertain, of gender, race and class. While psychiatry as social control has some degree of purchase here, more valuable is an attempt to discern the particular ways in which certain forms of sexual behaviour were understood in diagnostic terms. Men who had sex with Africans, we see, tended to be diagnosed as 'depressed' on arrival at the hospital but were judged to be mentally normal consequently. Women, by contrast, were liable to be diagnosed as psychopathic, a diagnosis, I argue, that helped to explain the uniquely transgressive status of impoverished European women living alone in the margins of white society. Unlike white men, moreover, women did not have to have sex with non-Europeans to transgress sexual codes: this is because female poverty was a sexual problem in a way that male poverty decidedly was not. Poor white women were marked by uncertainty over their sexual behaviour—and dubious racial identity in its turn—and the problem of social contamination was described by reference both to the polluted racial ancestry of an individual and to the prospective contamination of healthy racial stocks. This article aims to address current historical debates around sex and empire, 'white subalternity' and the social history of psychiatry and mental health. All names have been changed to protect patient anonymity.

Economic inequality and child stunting in Bangladesh and Kenya: an investigation of six hypotheses

Consistent with the increasing focus on issues of equity in developing countries, I extend the literature analyzing the relationship between economic inequality and individual health to the developing world. Using survey data from Bangladesh and Kenya with economic status measured by a wealth index and with three different geographic definitions of community, I analyze six competing hypotheses for how economic inequality may be related to stunting among children younger than 5 years old. I find little support for the predominant hypothesis that economic inequality as measured by a Gini index is an important predictor of individual health. Instead, I find that the difference between a household's wealth and the mean household wealth in the community is the measure of economic inequality that is most closely related to stunting in these countries. In particular, a 1 standard deviation increase in household wealth relative to the community mean is associated with a 30–32 percent decrease in the odds of stunting in Bangladesh and a 16–21 percent decrease in the odds of stunting in Kenya.

Auditory and visual novelty processing in normally-developing Kenyan children

OBJECTIVE

The aim of this study was to describe the normative development of the electrophysiological response to auditory and visual novelty in children living in rural Kenya.

METHODS

We examined event-related potentials (ERPs) elicited by novel auditory and visual stimuli in 178 normally-developing children aged 4-12 years (86 boys, mean 6.7 years, SD 1.8 years and 92 girls, mean 6.6 years, SD 1.5 years) who were living in rural Kenya.

RESULTS

The latency of early components (auditory P1 and visual N170) decreased with age and their amplitudes also tended to decrease with age. The changes in longer-latency components (Auditory N2, P3a and visual Nc, P3a) were more modality-specific; the N2 amplitude to novel stimuli decreased with age and the auditory P3a increased in both latency and amplitude with age. The Nc amplitude decreased with age while visual P3a amplitude tended to increase, though not linearly.

CONCLUSIONS

The changes in the timing and magnitude of early-latency ERPs likely reflect brain maturational processes. The age-related changes to auditory stimuli generally occurred later than those to visual stimuli suggesting that visual processing matures faster than auditory processing.

SIGNIFICANCE

ERPs may be used to assess children's cognitive development in rural areas of Africa.

East Africa's pastoralist emergency: is climate change the straw that breaks the camel's back?

The global warming trend of climate change is having severe adverse effects on the livelihoods of the Turkana pastoralists of northwestern Kenya. Care has to be taken in making assertions about the impact of climate change. The biggest effects may come not from lower average rainfall but from a widening of the standard deviation as weather extremes become more frequent. In a region already prone to drought, disease and conflict, climate change, access to modern weapons and new viral livestock diseases are now overwhelming pastoralists' coping capacity and deepening the region's roughly 30-year dependency on famine relief. This article examines the livelihood strategies of the Turkana and several poverty reduction programmes currently established, while addressing the reality that traditional pastoralism may no longer be a viable livelihood option, given the effects of climate change, disease and the ensuing conflict over diminishing resources. The findings conclude that the future for traditional Turkana pastoralists is dismal because they continue to depend on an environment that may no longer support them. Humanitarians are recommended to shift their focus to advocate and invest in alternative livelihood strategies that generate economic independence and help the Turkana adapt to their changing environment.

Entomophagy among the Luo of Kenya: a potential mineral source?

Primary objective To determine the iron, zinc, and calcium content in different insects commonly eaten among the Luo of Kenya. Research design A cross-sectional design was chosen for the study in order to determine the insects eaten and their mineral content during a specific season.Methods and procedures Five different insect species were identified and collected with the help of local informants in the Nyang'oma sublocation of the Bondo district in western Kenya, and were analysed for iron, zinc and calcium contents. Main outcomes and results The iron content ranged from 18 to 1562 mg/100 g dry matter, the zinc content from 8 to 25 mg/100 g, and the calcium content from 33 to 341 mg/100 g in five different insects, onyoso mammon (ant), oyala (termite), ogawo (termite), agaor (termite), onjiri mammon (cricket). Conclusions Insect eating could prove to be a valuable measure to combat, especially, iron and zinc deficiency in developing countries.

HIV voluntary counselling and testing for African communities in London: learning from experiences in Kenya

OBJECTIVES

To explore the feasibility and acceptability of translating a successful voluntary counselling and testing (VCT) service model from Kenya to African communities in London.

METHODS

Qualitative study with focus group discussions and a structured workshop with key informants. Five focus group discussions were conducted in London with 42 participants from 14 African countries between August 2006 and January 2007. A workshop was held with 28 key informants. Transcripts from the group discussions and workshop were analysed for recurrent themes.

RESULTS

Participants indicated that a community-based HIV VCT service would be acceptable to African communities in London, but also identified barriers to uptake: HIV-related stigma, concerns about confidentiality, and doubts about the ability of community-based services to maintain professional standards of care. Workshop participants highlighted three key requirements to ensure feasibility: (a) efficient referrals to sexual health services for the newly diagnosed; (b) a locally appropriate testing algorithm and quality assurance scheme; (c) a training programme for VCT counsellors.

CONCLUSIONS

Offering community-based VCT with rapid HIV tests appears feasible within a UK context and acceptable to African communities in London, provided that clients' confidentiality is ensured and appropriate support is given to the newly diagnosed. However, the persistence of concerns related to HIV-related stigma among African communities suggests that routine opt-out testing in healthcare settings may also constitute an effective approach to reducing the proportion of late diagnoses in this group. HIV service models and programmes from Africa constitute a valuable knowledge base for innovative interventions in other settings, including developed countries.

Developing a nursing database system in Kenya

OBJECTIVE

To describe the development, initial findings, and implications of a national nursing workforce database system in Kenya.

PRINCIPAL FINDINGS

Creating a national electronic nursing workforce database provides more reliable information on nurse demographics, migration patterns, and workforce capacity. Data analyses are most useful for human resources for health (HRH) planning when workforce capacity data can be linked to worksite staffing requirements. As a result of establishing this database, the Kenya Ministry of Health has improved capability to assess its nursing workforce and document important workforce trends, such as out-migration. Current data identify the United States as the leading recipient country of Kenyan nurses. The overwhelming majority of Kenyan nurses who elect to out-migrate are among Kenya's most qualified.

CONCLUSIONS

The Kenya nursing database is a first step toward facilitating evidence-based decision making in HRH. This database is unique to developing countries in sub-Saharan Africa. Establishing an electronic workforce database requires long-term investment and sustained support by national and global stakeholders.

New plans for housing in urban Kenya, 1939-63

Until about 1939, guided by a policy of trusteeship, the colonial government in Kenya limited the number of Africans in urban areas. As elsewhere in East and Central Africa, employers and municipalities were supposed to provide only 'bachelor' housing for unaccompanied African men. After 1939, encouraged by London, the Kenyan government began to promote a policy of development which implied urbanization. The permanent presence of Africans in towns was accepted, as was the growing responsibility of municipalities for the provision of housing for families as well as for bachelors. Municipalities began to plan for new types of housing, with more community facilities in new types of neighbourhood layouts. From the early 1940s, a wave of construction created many thousands of new dwellings in all major urban areas, but only a minority were designed for families. Many women and children were accommodated in 'bachelor' housing where they were compensated through rental subsidies. Although Kenya's housing initiatives in the late colonial period did not satisfy all of the rapidly growing urban needs, they were a substantial achievement.

The cost of health professionals' brain drain in Kenya

BACKGROUND

Past attempts to estimate the cost of migration were limited to education costs only and did not include the lost returns from investment. The objectives of this study were: (i) to estimate the financial cost of emigration of Kenyan doctors to the United Kingdom (UK) and the United States of America (USA); (ii) to estimate the financial cost of emigration of nurses to seven OECD countries (Canada, Denmark, Finland, Ireland, Portugal, UK, USA); and (iii) to describe other losses from brain drain.

METHODS

The costs of primary, secondary, medical and nursing schools were estimated in 2005. The cost information used in this study was obtained from one non-profit primary and secondary school and one public university in Kenya. The cost estimates represent unsubsidized cost. The loss incurred by Kenya through emigration was obtained by compounding the cost of educating a medical doctor and a nurse over the period between the average age of emigration (30 years) and the age of retirement (62 years) in recipient countries.

RESULTS

The total cost of educating a single medical doctor from primary school to university is 65,997 US dollars; and for every doctor who emigrates, a country loses about 517,931 US dollars worth of returns from investment. The total cost of educating one nurse from primary school to college of health sciences is 43,180 US dollars; and for every nurse that emigrates, a country loses about 338,868 US dollars worth of returns from investment.

CONCLUSION

Developed countries continue to deprive Kenya of millions of dollars worth of investments embodied in her human resources for health. If the current trend of poaching of scarce human resources for health (and other professionals) from Kenya is not curtailed, the chances of achieving the Millennium Development Goals would remain bleak. Such continued plunder of investments embodied in human resources contributes to further underdevelopment of Kenya and to keeping a majority of her people in the vicious circle of ill-health and poverty. Therefore, both developed and developing countries need to urgently develop and implement strategies for addressing the health human resource crisis.

"Taming tradition": medicalized female genital practices in western Kenya

This article considers the question of female genital practices at the hands of health workers in western Kenya. Recent articles in Medical Anthropology Quarterly have critically engaged with the biomedical arguments condemning such practices. This article studies the case of medicalized circumcision in which biomedical concerns over health risks have become incorporated in their vernacular practice. Although some suggest that medicalization may provide a harm-reduction strategy to the abandonment of the practice, research in one region challenges this suggestion. It argues that changing and conflicting ideologies of gender and sexuality have led young women to seek their own meaning through medicalized practice. Moreover, attributing this practice to financial motivations of health workers overlooks the way in which these "moral agents" must be situated within their social and cultural universe. Together, these insights challenge the view that medicine can remain neutral in the mediation of tradition.

Successful treatment of visceral leishmaniasis with liposomal amphotericin B

We report a case of a 26-year-old female from Kenya who suffered from intermittent fever of unknown origin for one month. The major findings on admission were pancytopenia associated with considerable splenomegaly. The diagnosis was established by visualisation of amastigotes in bone marrow biopsy and by detection of antibodies to Leishmania spp. in blood. The infection was treated intravenously with liposomal amphotericin B for five days. The patient was afebrile after the first infusion. No relapse was reported.

Erectile dysfunction and its correlates among the Ariaal of northern Kenya

To expand our crosscultural understanding of erectile dysfunction, we investigated erectile dysfunction among Ariaal men, pastoral nomads of northern Kenya. To measure erectile dysfunction, we administered the International Index of Erectile Function (IIEF-5) to 198 men aged 20 y and older during interviews. Marital status and anthropometric measures of body composition were also obtained. Men were classified into 10-y age groups. ANOVA revealed that erectile dysfunction increases with age (P<0.0005), with men 60 y and older showing significantly higher erectile dysfunction compared with men in their 20s, 40s and 50s. In a MANCOVA model, erectile dysfunction increased with age group (P<0.001), was negatively related to right-hand grip strength (P<0.01) and negatively related to number of wives (P<0.05). In addition, there was a significant interaction between age group and marital status (P<0.01). Erectile dysfunction showed no independent relationship to measures of body composition, including body mass index, fat free mass and percentage body fat. These findings provide further evidence of age-related increases in erectile dysfunction, even when factors commonly associated with erectile dysfunction (eg, metabolic complications of obesity, use of medicines causing erectile dysfunction) are absent. The finding that number of wives is negatively related to erectile dysfunction may represent the specific cultural conditions (political power and wealth) associated with polygyny among the Ariaal.

Training response of adolescent Kenyan town and village boys to endurance running

To investigate the response to endurance training on physiological characteristics, 10 Nandi town boys and 14 Nandi village boys 16.5 and 16.6 years of age, respectively, from western Kenya performed 12 weeks of running training. The study was performed at altitude (approximately 2000 m.a.s.l. approximately 595 mm Hg). Training heart rate and speed were registered during every training session throughout the entire training period. While town and village boys trained at similar heart rates (172.1 vs. 172.5 beats min(-1)), the training speed of the town boys was 9% lower compared with the village boys (12.4 vs. 13.6 km h(-1), P<0.001). Significant increases in VO2max were observed in the town boys (from 50.3 to 55.6 mL kg(-1) min(-1), P<0.001) and in village boys (from 56.0 to 59.1 mL kg(-1) min(-1), P<0.002). Significant decreases in submaximal heart rate (from 172.4 to 160.3 beats min(-1) (P<0.005)), blood lactate (from 2.7 to 1.4 mmol L(-1) (P<0.005)) and ammonia concentration (from 102.0 to 71.4 micromol L(-1) (P<0.01)) at 9.9 km h(-1) were observed in the town boys, while similar decreases in heart rate (from 170.2 to 159.2 beats min(-1) (P<0.001)), blood lactate (from 2.4 to 1.4 mmol L(-1) (P<0.001)) and ammonia concentration (from 102.5 to 72.7 micromol L(-1) (P<0.001)) at 10.9 km h(-1) were observed in the village boys. The oxygen cost of running was decreased from 221.5 to 211.5 mL kg(-1) km(-1) (P<0.03) in the town boys and from 220.1 to 207.2 mL kg(-1) km(-1) (P<0.01) in the village boys. The 5000 m performance time of the town boys was significantly greater than that of the village boys (20.25 vs. 18.42 min (P = 0.01)). It is concluded that no difference was observed in trainability with respect to VO2max, running economy, submaximal heart rate, and submaximal blood lactate and ammonia concentration between Kenyan Nandi town and village boys. The higher performance level of the village boys was likely due to a higher VO2max of these boys.

Community based interventions as a strategy to combat desertification in the arid and semi-arid rangelands of Kajiado District, Kenya

Vegetation degradation, especially the disappearance of woody vegetation and a diminished grass cover, has aroused the concern of the Maasai community (semi-nomadic pastoralists) of Kajiado District, Kenya. The district is one of Kenya's arid and semi-arid districts. Over recent years, they have observed their land resources deteriorate due to the desertification process caused by the land use practices of man. They have identified indicators of desertification such as increase of bare lands, which have been invaded by previously unknown grasses and weeds that are of no economic value, and also the disappearance of some useful plant species. It is due to the above concerns that a group of 30 farmers have been very keen to participate in on-farm research to strategize on ways to halt and even reverse the desertification process. The participatory research has identified useful trees that the farmers have been planting around homesteads, as woodlots on their farms to provide woodfuel, shade, and to act as windbreaks. They have also identified species for planting as live fences instead of using thorny tree branches as fencing material, which contributes further to the desertification process. Due to the termite menace on young tree seedlings, the farmers use indigenous knowledge to prepare concoctions using locally available materials, which they apply to planting holes and on seedlings. During awareness campaigns, the farmer research group highlights the need to conserve vegetation resources and also expounds on the concept of planting two trees after one is felled.

Elevation of Immune Activation in Kenyan Women is Associated with Alterations in Immune Function: Implications for Vaccine Development

The infectious burden leading to immune activation can vary between different populations and lead to various immune dysfunctions. We compared the effect of immune activation on apoptosis and T cell function in HIV uninfected individuals from Nairobi, Kenya (n=34), and Winnipeg, Canada (n=10). Women from Nairobi had a significantly greater number of CD8+ T cells expressing the activation markers CD38 and HLA DR. Kenyan women also had significantly higher levels of CTLA-4+ CD4 and CD8+ T cells, and reduced levels of CD28+ CD8+ cells. Levels of CD95+ CD4+ T cells were higher in Kenyan women and, correspondingly, showed higher levels of spontaneous apoptosis. Kenyan women also demonstrated hyper-responsiveness to T cell activation as assessed by interferon gamma production. This study demonstrates that in a population of Kenyan women with high levels of T cell activation, there were also elevated levels of T cell apoptotic death and hyper-responsiveness. These differences may influence the efficacy of immune responses to pathogens and must be considered when testing candidate vaccines.

Trends in antenatal human immunodeficiency virus prevalence in Western Kenya and Eastern Uganda: evidence of differences in health policies?

OBJECTIVE

To observe recent trends in human immunodeficiency virus (HIV) prevalence in antenatal clinic attendees to determine if previously noted falls in HIV prevalence are occurring on both sides of the Kenyan-Ugandan border. Design An ecologic study was conducted at the district level comparing HIV prevalence rates over time using data available through reports published by the Kenyan and Ugandan Ministries of Health and UNAIDS.

METHODS

Sentinel sites were compared with respect to population, ethnicity, language group, and the prevalence of circumcision practice. The prevalence of HIV found at each sentinel site was recorded for the years 1990-2000 and analysed visually and by conducting bivariate correlations.

RESULTS

Ethnographic analysis revealed a wide mix of ethnic and language groups and circumcision rates on both sides of the border. All sentinel surveillance sites in Uganda showed trends towards decreasing HIV prevalence, with three of five sites showing statistically significant declines (r = -0.87, -0.85, -0.86, P < 0.05). In contrast, all of the surveillance sites in Kenya showed trends toward increasing HIV prevalence, with two of the five sites showing statistically significant increases (r = 0.62, 0.84, P < 0.05).

CONCLUSIONS

The declines in HIV prevalence occurring in Uganda are not being seen in geographically proximal districts of Kenya. No obvious differences in ethnic groupings or their associated prevalence of circumcision appeared to explain these differences. This suggests that decreasing HIV prevalence in Uganda is not due to the natural course of the epidemic but reflects real success in terms of HIV control policies.

Knowledge and practice about cervical cancer and Pap smear testing among patients at Kenyatta National Hospital, Nairobi, Kenya

Invasive cervical cancer (ICC) is the leading cause of cancer-related death among women in developing countries. Population-based cytologic screening and early treatment does reduce morbidity and mortality associated with cervical cancer. Some of the factors related to the success of such a program include awareness about cervical cancer and its screening. The objective of this study was to assess knowledge and practice about cervical cancer and Pap smear testing among cervical cancer and noncancer patients using a structured questionnaire to obtain information. Fifty-one percent of the respondents were aware of cervical cancer while 32% knew about Pap smear testing. There were no significant differences in knowledge between cervical cancer and noncancer patients. Health care providers were the principal source of information about Pap testing (82%). Only 22% of all patients had had a Pap smear test in the past. Patients aware of cervical cancer were more likely to have had a Pap smear test in the past. The level of knowledge is low among ICC and noncancer patients. There is need to increase the level of knowledge and awareness about ICC and screening among Kenyan women to increase uptake of the currently available hospital screening facilities.

Trauma exposure and post-traumatic stress symptoms in urban African schools. Survey in CapeTown and Nairobi

BACKGROUND

There is a lack of comparative data on the prevalence and effects of exposure to violence in African youth.

AIMS

We assessed trauma exposure, post-traumatic stress symptoms and gender differences in adolescents from two African countries.

METHOD

A sample of 2041 boys and girls from 18 schools in CapeTown and Nairobi completed anonymous self-report questionnaires.

RESULTS

More than 80% reported exposure to severe trauma, either as victims or witnesses. Kenyan adolescents, compared with South African, had significantly higher rates of exposure to witnessing violence (69% v. 58%), physical assault by a family member (27% v. 14%) and sexual assault (18% v. 14%). But rates of current full-symptom post-traumatic stress disorder (PTSD) (22.2% v. 5%) and current partial-symptom PTSD (12% v. 8%) were significantly higher in the South African sample. Boys were as likely as girls to meet PTSD symptom criteria.

CONCLUSIONS

Although the lifetime exposure to trauma was comparable across both settings, Kenyan adolescents had much lower rates of PTSD. This difference may be attributable to cultural and other trauma-related variables. High rates of sexual assault and PTSD, traditionally documented in girls, may also occur in boys and warrant further study.

Sedentism, seasonality, and economic status: A multivariate analysis of maternal dietary and health statuses between pastoral and agricultural Ariaal and Rendille communities in northern Kenya

This paper examines longitudinal data to assess the effects of the recent transition from pastoralism to sedentary agriculture for Ariaal and Rendille mothers in northern Kenya. Dietary, morbidity, and anthropometric data resulting from bimonthly repeated surveys of the pastoral community of Lewogoso and the sedentary agricultural community of Songa, covering the period from September 1994-July 1995, were used to test two hypotheses: 1) that sedentism is associated with changes in diet, seasonality, morbidity, and socioeconomic differentiation, and 2) that these changes affect maternal body composition. The first hypothesis is partly supported, with starch replacing milk in the sedentary diet. Repeated-measures multivariate analysis of variance revealed no seasonal effects for diet in the agricultural sample, while starch consumption was significantly affected by seasonality for the pastoral sample. The agricultural community also featured economic dietary disparities favoring wealthier mothers, while no such effect was found in the pastoral community. However, no seasonal or economic effects were found for morbidity patterns in either sample. The second hypothesis is also partially supported, as a generalized estimating equations analysis revealed differences in the way diet and economic strata influence maternal anthropometric values. Economic status was significantly associated with maternal arm-fat area in Lewogoso. Milk was a significant factor associated with maternal weight and arm-muscle area in Songa. These findings are discussed in light of development policy implications.
