Determinants of unprotected sex among HIV-positive patients in South Africa
(Taylor and Francis Ltd, 2005) Olley, B. O.; Seedat, S.; Gxamza, F.; Reuter, H.; Stein, D. J.
This study examined the prevalence of unprotected sex, other sexual risk behaviours, and factors associated with unprotected sex among men and women recently diagnosed with HIV in South Africa. One hundred and forty-nine outpatients (44 males and 105 females) were assessed, of whom 101 were sexually active at least 6 months prior to study entry. Subjects were asked about sexual risk behaviours with reference to their most recent sexual encounter. Logistic regression analysis was employed to determine the predictors of condom use, with independent variables selected from five general categories: (1) sociodemographic characteristics; (2) situational characteristics regarding sexual intercourse (i.e. alcohol or drugs used before intercourse); (3) clinical diagnoses; (4) negative life events; and (5) coping styles. Fifty-five patients (19 males and 36 females), representing 54.4% of those sexually active in the 6 months preceding the study, had not used a condom during the most recent intercourse. Compared with those who used condoms, participants who did not significantly reported shorter duration of HIV infection (t= -2.7, p < 0.001), have a current partner (x2= 3.98, p= 0.005), and lack knowledge of their partner’s HIV status (x2= 4.78, p= 0.004). Also they were significantly more likely to engage in denial (t= 3.2, p < 0.002) and to use substances (t= 1.98, p < 0.05) as a means of coping. Logistic regression showed that shorter duration of illness (odds ratio (OR)= 1.2, 95% confidence interval (CI)= 1.01- 1.41) and coping styles characterized by denial (OR= 0.6, 95% CI= 0.45- 0.96) were significantly associated with unprotected sex. These data suggest the need for interventions to further reduce sexual risk behaviours in HIV-positive patients in South Africa.
Persistence of psychiatric disorders in a cohort of HIV/AIDS patients in South Africa: A 6-month follow-up study
(Elsevier Inc, 2006) Olley, B. O.; Seedat, S.; Stein, D. J.
Background: Psychiatric disorders in HIV/AIDS are common, emerging soon after diagnosis or during the subsequent course of illness. However, there are few prospective studies on the rates of psychiatric disorders in HIV/AIDS, particularly in the context of the developing world. Methods: Sixty-five patients with recently diagnosed HIV were interviewed on presentation to a hospital-based HIV clinic and then 6 months later. On both interviews, the patients were assessed using the MINI International Neuropsychiatric Interview, the Carver Brief COPE, and the Sheehan Disability Scale. Exposure to negative life events and risk behaviors was also evaluated. Results: The overall prevalence of psychiatric disorders in the follow-up period remained high (56% of patients had at least one psychiatric disorder at baseline, and 48% of patients had at least one psychiatric disorder at 6 months). Depression and posttraumatic stress disorder (PTSD) were the most prevalent disorders at both baseline (34.9% and 14.8%) and follow-up (26% and 20%), respectively. More than half of all patients with depression at baseline improved (16 of 29; 55.1%). However, there was a new onset of both depression (4 of 49; 8.1%) and PTSD (12 of 17; 70.5%) on follow-up. In univariate analysis, depression on follow-up was significantly associated with: (a) disability in work/social/family functioning, (b) greater number of negative life events, and (c) a decline in CD4 lymphocyte count. Univariate analysis also revealed that a diagnosis of PTSD on follow-up was significantly associated with (a) a longer duration of infection and (b) baseline disability in work/social/family functioning. However, in multivariate analysis, only disability scores predicted the diagnoses of major depression and PTSD on follow-up assessment. Persistence of risky sexual behaviour was also noted, with a significantly higher number of participants reporting nonuse of condom on follow-up. There appeared to be a shift from maladaptive coping behaviors to more adaptive coping behaviors over the 6-month period. Conclusion: The rate of psychiatric disorders in HIV/AIDS patients was consistent over time. These findings emphasize the importance of regular evaluation for psychiatric disorders in HIV/AIDS patients, not only at the commencement of treatment but also during subsequent follow-up visits.
Post-traumatic stress disorder among recently diagnosed patients with HIV/AIDS in South Africa
(2005-07) Olley, B. O; Zeier, M. D.; Seedat, S.; Stein, D. J.
This study examined the prevalence of and factors associated with post-traumatic stress disorder in recently diagnosed HIV/AIDS patients in South Africa. One hundred and forty-nine (44 male, 105 female) recently diagnosed HIV/AIDS patients (mean duration since diagnosis= 5.8 months, = 4.1) were evaluated. Subjects were assessed using the MINI International Neuropsychiatric Interview (MINI), the Carver Brief COPE coping scale and the Sheehan Disability Scale. In addition, previous exposures to trauma and past risk behaviours were assessed. Twenty-two patients (14.8%) met criteria for PTSD. Current psychiatric conditions more likely to be associated with PTSD included major depressive disorder (29% in PTSD patients versus 7% in non-PTSD patients, p= 0.004), suicidality (54% versus 11%, p= 0.001) and social anxiety disorder (40% versus 13%, p= 0.04). Further patients with PTSD reported significantly more work impairment and demonstrated a trend towards higher usage of alcohol as a means of coping. Discriminant function analysis indicated that female gender and a history of sexual violation in the past year were significantly associated with a diagnosis of PTSD. Patients whose PTSD was a direct result of an HIV/AIDS diagnosis (8/22) did not differ from other patients with PTSD on demographic or clinical features. In the South African context, PTSD is not an uncommon disorder in patients with HIV/AIDS. In some cases, PTSD is secondary to the diagnosis of HIV/AIDS but in most cases it is seen after other traumas, with sexual violation and intimate partner violence in women being particularly important.
Predictors of major depression in recently diagnosed patients with HIV/AIDS in South Africa
(Mary Ann Liebert, Inc., 2004) Olley, B. O; Seedat, S.; Nei, D. G.; Stein, D. J.
There is increasing evidence that major depression impacts the course of HIV infection, yet few studies have explored demographic and clinical predictors of depression in people who with HIV/AIDS. This study investigated predictors of depression (e.g., demographic and clinical variables, negative life events, and coping response) among outpatients with recently diagnosed HIV/AIDS patients in South Africa. One hundred forty-nine recently diagnosed HIV/AIDS patients (44 males and 105 females; mean time since diagnosis= 5.8, standard deviation [SD] 4.1) were evaluated. Subjects were assessed using the Mini International Neuropsychiatric Interview (MINI), the Carver Brief COPE coping scale, and the Sheehan Disability Scale. In addition, previous exposures to trauma and past risk behaviors were assessed. Three variables: gender (odd ratio [OR]= 1.23; 95% confidence interval [CI] 1.56, 1.93), impact of negative life events (OR= 1.13; CI, 1.03, 1.23), and disability (OR= 1.51, CI, 1.28, 1.80) predicted current major depression. It is well known from non-HIV populations that female gender and increased negative life events predict depression. These data also emphasize the importance of these links in HIV.
Psychopathology and coping in recently diagnosed HIV/AIDS patients- the role of gender
(2003-12) Olley, B. O; Gxamza, F.; Seedat, S.; Theron, H.; Taljaard, J.; Reid, E.; Reuter, H.; Stein, D. J.
Although there is growing literature on the psychological responses to and the psychopathology associated with HIV/AIDS, few investigations have focused on the role of gender. This study compared psychiatric morbidity, coping responses, and disability in male and female outpatients recently diagnosed with HIV/AIDS. Method. One hundred and forty-nine patients (44 male, 105 female) with HIV/AIDS (mean ± standard deviation (SD) months since diagnosis 5.8 ± 4.1) attending an infectious diseases clinic at Tygerberg Hospital, Cape Town, were evaluated. Subjects were assessed using the MINI International Neuropsychiatric Interview (MINI), the Carver Brief COPE, and the Sheehan Disability Scale. In addition, negative life events and risk behaviours were evaluated. Results. Fifty-six per cent of patients were diagnosed with a psychiatric disorder, most commonly major depression (34.9%), dysthymic disorder (21.5%), post-traumatic stress disorder (14.8%), and alcohol dependence (10.1 %). There were no significant gender differences in the prevalence of mood disorders in the sample. Men, however, were more likely than women to meet diagnostic criteria for alcohol abuse or dependence, and to engage in certain risky sexual behaviours. Women were more likely to suffer from post-traumatic stress disorder, and to use coping strategies of planning and religion to deal with the illness. There were no significant gender differences in disability. Conclusion. Psychiatric disorders are common in recently diagnosed HIV/AIDS patients in South Africa. Clinicians should be aware of the high prevalence of mood disorders in both men and women, and of gender-different responses such as increased alcohol and substance use and more risky sexual behaviour in men.
