The social and economic impact of epilepsy in Zambia: a cross-sectional study.

BACKGROUND: Among the 40 million people with epilepsy worldwide, 80% reside in low-income regions where human and technological resources for care are extremely limited. Qualitative and experiential reports indicate that people with epilepsy in Africa are also disadvantaged socially and economically, but few quantitative systematic data are available. We sought to assess the social and economic effect of living with epilepsy in sub-Saharan Africa. METHODS: We did a cross-sectional study of people with epilepsy concurrently matched for age, sex, and site of care to individuals with a non-stigmatised chronic medical condition. Verbally administered questionnaires provided comparison data for demographic characteristics, education, employment status, housing and environment quality, food security, healthcare use, personal safety, and perceived stigma. FINDINGS: People with epilepsy had higher mean perceived stigma scores (1.8 vs 0.4; p<0.0001), poorer employment status (p=0.0001), and less education (7.1 vs 9.4 years; p<0.0001) than did the comparison group. People with epilepsy also had less education than their nearest-age same sex sibling (7.1 vs 9.1 years; p<0.0001), whereas the comparison group did not (9.4 vs 9.6 years; p=0.42). Housing and environmental quality were poorer for people with epilepsy, who had little access to water, were unlikely to have electricity in their home (19%vs 51%; p<0.0001), and who had greater food insecurity than did the control group. During pregnancy, women with epilepsy were more likely to deliver at home rather than in a hospital or clinic (40%vs 15%; p=0.0007). Personal safety for people with epilepsy was also more problematic; rape rates were 20% among women with epilepsy vs 3% in the control group (p=0.004). INTERPRETATION: People with epilepsy in Zambia have substantially poorer social and economic status than do their peers with non-stigmatised chronic medical conditions. Suboptimum housing quality differentially exposes these individuals to the risk of burns and drowning during a seizure. Vulnerability to physical violence is extreme, especially for women with epilepsy.

Zambian health care workers' knowledge, attitudes, beliefs, and practices regarding epilepsy.

OBJECTIVE: Zambia suffers from a physician shortage, leaving the provision of care for those with epilepsy to nonphysician health care workers who may not be adequately trained for this task. These individuals are also important community opinion leaders. Our goal in this study was to determine the knowledge, attitudes, beliefs, and practices of these health care workers with respect to epilepsy. METHODS: Health care workers in urban and rural districts of Zambia completed a self-administered, 48-item questionnaire containing items addressing demographics, personal experience with epilepsy, social tolerance, willingness to provide care, epilepsy care knowledge, and estimates of others' attitudes. Analyses were conducted to assess characteristics associated with more epilepsy care knowledge and social tolerance. RESULTS: The response rate was 92% (n=276). Those who had received both didactic and bedside training (P=0.02) and more recent graduates (P=0.007) had greater knowledge. Greater knowledge was associated with more social tolerance (P=0.005), but having a family member with epilepsy was not (P=0.61). Health care workers were generally willing to provide care to this patient population, but approximately 25% would not allow their child to marry someone with epilepsy and 20% thought people with epilepsy should not marry or hold employment. Respondents reported that people with epilepsy are feared and/or rejected by both their families (75%) and their community (88.8%). CONCLUSIONS: Knowledge gaps exist particularly in acute management and recognition of partial epilepsy. More recent graduates were more knowledgeable, suggesting that curriculum changes instituted in 2000 may be improving care. Health care workers expressed both personal and professional reservations about people with epilepsy marrying. In addition to improving diagnosis and treatment skills, educational programs must address underlying attitudes that may worsen existing stigmatizing trends.

Zambian teachers: what do they know about epilepsy and how can we work with them to decrease stigma?

PURPOSE: Teachers play a central role in determining access to education and may mediate epilepsy-associated stigma. We developed and administered a teacher-specific survey to assess teachers' knowledge, attitudes, behaviors, and practices (KABPs) regarding epilepsy in Zambia and social and demographic determinants of KABPs. METHODS: In 2004, we surveyed 171 teachers in urban and rural regions using a 46-item questionnaire. Knowledge and tolerance composite scores were developed and analyses completed to identify demographic and social determinants of KABPs and evaluate whether generic tolerance questions were associated with stigmatizing practices. RESULTS: The response rate was 93% (n=159). Knowledge regarding epilepsy ranged broadly. Misattribution was evident for etiology (spirit possession 17.3%; contagion 28.2%; witchcraft 16.8%), and individuals with poorer knowledge were more likely to recommend traditional healers (p=0.0004) rather than physicians for epilepsy care. Higher knowledge was associated with higher tolerance (p=0.01). Tolerance was highest among urban residents (p=0.002) and individuals with personal familiarity/experience with epilepsy. More tolerant teachers were less likely to report stigmatizing practices, such as ejecting children with seizures from school. CONCLUSIONS: Teacher-targeted interventions aimed at reducing epilepsy-associated stigma and its sequelae in Zambia should include both an educational component and a social component in which teachers are exposed to a person or persons with the condition. Education programs led by person(s) with epilepsy may be ideal.

Clinical and demographic features of treated first-episode psychotic disorders: a Zambian study.

BACKGROUND: There is a relative lack of information about the epidemiology of psychotic disorders in the developing world. The aim of this pragmatic study was to describe the correlates of first-episode psychosis in the central African nation of Zambia. METHOD: Selected clinical and demographic variables were collected on patients with psychotic disorders presenting for the first time at the only psychiatric hospital in Zambia (Chainama Hills College Hospital, Lusaka). RESULTS: During the study period, 160 subjects were admitted to the hospital with the first episode of a psychotic disorder. The male to female sex ratio was 2.5:1, with the median age of first admission for both sexes being 26 years. Half of the subjects had a duration of untreated psychosis one month or less. Recent alcohol and other drug abuse was common in males (56%). Clinical evidence of HIV/AIDs was found in 9% of those admitted. Approximately one-third of the subjects had attended a traditional healer for their psychotic symptoms prior to admission. CONCLUSIONS: Understanding the profile of treated first-episode psychosis in the developing world can help optimize the development of local services. Furthermore, characterizing differences in the epidemiology of psychosis between populations may help generate factors that could influence its cause and course.

Violence and abuse among HIV-infected women and their children in Zambia: a qualitative study.

HIV and violence are two major public health problems increasingly shown to be connected and relevant to international mental health issues and HIV-related services. Qualitative research is important due to the dearth of literature on this association in developing countries, cultural influences on mental health syndromes and presentations, and the sensitive nature of the topic. The study presented in this paper sought to investigate the mental health issues of an HIV-affected population of women and children in Lusaka, Zambia, through a systematic qualitative study. Two qualitative methods resulted in the identification of three major problems for women: domestic violence (DV), depression-like syndrome, and alcohol abuse; and children: defilement, DV, and behavior problems. DV and sexual abuse were found to be closely linked to HIV and alcohol abuse. This study shows the local perspective of the overlap between violence and HIV. Results are discussed in relation to the need for violence and abuse to be addressed as HIV services are implemented in sub-Saharan Africa.

Sexual behavior of HIV discordant couples after HIV counseling and testing.

BACKGROUND AND OBJECTIVES: Sexual behavior following voluntary HIV counseling and testing (VCT) is described in 963 cohabiting heterosexual couples with one HIV positive and one HIV negative partner ('discordant couples'). Biological markers were used to assess the validity of self-report. METHODS: Couples were recruited from a same-day VCT center in Lusaka, Zambia. Sexual exposures with and without condoms were recorded at 3-monthly intervals. Sperm detected on vaginal smears, pregnancy, and sexually transmitted diseases (STD) including HIV, gonorrhea, syphilis, and Trichomonas vaginalis were assessed. RESULTS: Less than 3% of couples reported current condom use prior to VCT. In the year after VCT, > 80% of reported acts of intercourse in discordant couples included condom use. Reporting 100% condom use was associated with 39-70% reductions in biological markers; however most intervals with reported unprotected sex were negative for all biological markers. Under-reporting was common: 50% of sperm and 32% of pregnancies and HIV transmissions were detected when couples had reported always using condoms. Positive laboratory tests for STD and reported extramarital sex were relatively infrequent. DNA sequencing confirmed that 87% of new HIV infections were acquired from the spouse. CONCLUSIONS: Joint VCT prompted sustained but imperfect condom use in HIV discordant couples. Biological markers were insensitive but provided evidence for a significant under-reporting of unprotected sex. Strategies that encourage truthful reporting of sexual behavior and sensitive biological markers of exposure are urgently needed. The impact of prevention programs should be assessed with both behavioral and biological measures.
