RESUMO
PURPOSE : To assess gender differences in COVID-19 related changes in home and work responsibilities longitudinally, and determine whether these differences, together with other potential risk and protective factors, are associated with depression, anxiety, and post-traumatic stress disorder (PTSD) symptomatology. METHOD: Symptoms of depression, anxiety, and PTSD were measured using an online survey instrument, between May 2020 and April 2021, in four waves completed at 3-monthly intervals. Analyses were based on data from the COvid MEntal healTh (COMET) survey which investigated the mental health effects of the COVID-19 outbreak spanning 13 countries on five continents in N = 7,909 participants. RESULTS: From the first to the last wave, women reported a greater increase in home and work responsibilities, and had higher depression, anxiety and PTSD scores compared to men. Women who reported a reduction in income due to the pandemic had higher depression scores. Working harder and experiencing a reduction in income were also associated with higher anxiety scores in women but not in men. Women were more likely to score above the cut-off for depression (32.5% vs 23.6%, p < .001), anxiety (21.2% vs 14.4%, p < .001) and PTSD (21.2% vs 14.4%, p < .001) than men during the first wave. Stronger reliance on socially supported coping mechanisms was a risk factor for depression, anxiety and PTSD in men and women. CONCLUSION: Women were more likely to report mental health problems which may be related to the gender disproportionate increase in home and work responsibilities but not necessarily due to COVID-19 stressors.
RESUMO
Childhood maltreatment is associated with wide-ranging psychopathology at all stages of life. In the current study, we investigated whether posttraumatic stress disorder (PTSD) severity mediated the association between childhood maltreatment and internalizing and externalizing disorders among 262 South African trauma-exposed adolescents (aged 12-18 years). Childhood maltreatment and PTSD symptom severity were assessed using the Childhood Trauma Questionnaire and the Child PTSD Checklist, respectively. Psychiatric disorders were assessed utilizing the Kiddie-Schedule for Affective Disorders and Schizophrenia-Present and Lifetime version and were grouped into internalizing or externalizing disorders. Hierarchal logistic regression was used to assess the association of childhood maltreatment subtype with internalizing and externalizing disorders, controlling for age and gender, with PTSD symptom severity added to the final model. We found that sexual abuse was significantly associated with internalizing disorders, although this effect was no longer significant when PTSD was added to the model demonstrating that PTSD mediated the association between sexual abuse and internalizing disorders. Physical abuse, but not PTSD, was associated with externalizing disorders. Physical abuse, emotional neglect, and PTSD were associated with comorbid internalizing and externalizing disorders. These findings have implications for intervention and prevention strategies targeted at trauma-exposed adolescents with a history of childhood maltreatment.
RESUMO
Childhood trauma (CT) is well established as a potent risk factor for the development of mental disorders. However, the potential of adverse early experiences to exert chronic and profound effects on physical health, including aberrant metabolic phenotypes, has only been more recently explored. Among these consequences is metabolic syndrome (MetS), which is characterised by at least three of five related cardiometabolic traits: hypertension, insulin resistance/hyperglycaemia, raised triglycerides, low high-density lipoprotein and central obesity. The deleterious effects of CT on health outcomes may be partially attributable to dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis, which coordinates the response to stress, and the consequent fostering of a pro-inflammatory environment. Epigenetic tags, such as DNA methylation, which are sensitive to environmental influences provide a means whereby the effects of CT can be biologically embedded and persist into adulthood to affect health and well-being. The methylome regulates the transcription of genes involved in the stress response, metabolism and inflammation. This narrative review examines the evidence for DNA methylation in CT and MetS in order to identify shared neuroendocrine and immune correlates that may mediate the increased risk of MetS following CT exposure. Our review specifically highlights differential methylation of FKBP5, the gene that encodes FK506-binding protein 51 and has pleiotropic effects on stress responding, inflammation and energy metabolism, as a central candidate to understand the molecular aetiology underlying CT-associated MetS risk.

INTRODUCTION: Traumatic experiences that are varied in type and severity may lead to the development of Posttraumatic Stress Disorder (PTSD). Some trauma types present a higher conditional risk for PTSD owing to their nature and impact on growth and functioning. Few studies have investigated the conditional risk of PTSD in clinic referred adolescents in low- and middle-income countries. The aim of the study was to determine the conditional risk for PTSD based on various trauma types (car accidents, other serious accidents, fires, witnessing a natural disaster, witnessing a violent crime, being confronted with traumatic news, witnessing domestic violence, physical abuse and sexual abuse) and to stratify risk by gender. METHOD: Adolescents exposed to at least one Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV) qualifying trauma were referred to a research clinic in Cape Town, South Africa (n = 216). PTSD status was assessed using a clinician administered interview. Conditional risk was determined using backwards stepwise multiple logistic regression analysis for 1) the whole sample, 2) females only and 3) males only. Gender differences in exposure to trauma types were determined using chi-square tests and cross-tabulation. RESULTS: The prevalence of PTSD was 48.1% in the whole sample. Age (ß = .16, p = .048, OR 1.17), fire exposure (ß = 2.32, p = .036, OR 10.12) and sexual abuse (ß = .93, p = .001, OR 2.54) were significant predictors of PTSD in the whole sample with the model explaining 12.4% of the variance in PTSD status. Age (ß = .22, p = .041, OR 1.24) and sexual abuse (ß = .87, p = .018, OR 2.39) were significant predictors of PTSD in female participants and explained 9.8% of the variance in PTSD status. Being a victim of a violent crime (ß = .78 p = .100, OR 2.19) was the only remaining predictor of PTSD in male participants and showed a trend towards significance. The model explained 7% of the variance in PTSD status. CONCLUSIONS: The findings underscore the importance of timely identification of trauma, particularly, sexual abuse and violence. Longitudinal tracking of adolescents exposed to different trauma types may identify those in need of treatment and enhance our understanding of the lasting impact of trauma.

Mortuary workers are at high risk of developing depression and other psychiatric disorders owing to the nature of their work and exposure to deceased victims of violent deaths. Few studies have investigated mental health among mortuary workers in low- and middle-income countries. Participants (N = 45) were recruited from mortuaries in South Africa and completed a battery of questionnaires measuring depression, physical health, perceived stress, fear of blood/injury/mutilation, and resilience. Participants with self-reported depression and posttraumatic stress disorder (PTSD) comprised 13.3% and 4.4% of the sample, respectively. Inexperienced mortuary workers had a higher prevalence rate of depression (16.7%) compared with experienced workers (9.5%). Prevalence of PTSD did not differ significantly between inexperienced (4.2%) and experienced (4.8%) workers. Physical health, perceived stress, fear of blood/injury/mutilation, and resilience were significant predictors of depression in the combined group (experienced and inexperienced). However, perceived stress was the only significant predictor of depression, in multiple regression, in the combined group. Inexperienced workers had significantly higher levels of blood/injury/mutation fear and depression. Mortuary workers seem to be at increased risk of depression, especially inexperienced workers. Perceived poor health, lower levels of resilience, and blood/injury/mutilation fears may lead to increased perceived stress among mortuary workers, which may, in turn, lead to depression. Interventions focused on promoting mental health may be beneficial to all mortuary workers, and preparatory training related to mental health may be beneficial to inexperienced mortuary workers before occupational uptake.

BACKGROUND: Emergency healthcare workers, including trainees and individuals in related occupations are at heightened risk of developing posttraumatic stress disorder (PTSD) and depression owing to work-related stressors.We aimed to investigate the type, frequency, and severity of direct trauma exposure, posttraumatic stress symptoms and other psychopathology amongst paramedic trainees. In order to create a risk profile for individuals who are at higher occupational risk of developing PTSD, we examined risk and resilience factors that possibly contributed to the presence and severity of posttraumatic symptomatology. METHODS: Paramedic trainees (n = 131) were recruited from a local university. A logistic regression analysis was conducted using the explanatory variables age, gender, population group, trauma exposure, depression, alcohol abuse, alcohol dependence, resilience and social support. RESULTS: 94% of paramedic trainees had directly experienced trauma, with 16% meeting PTSD criteria. A high rate of depression (28%), alcohol abuse (23%) and chronic perceived stress (7%) and low levels of social support was found. The number of previous trauma exposures, depression, resilience and social support significantly predicted PTSD status and depression had a mediating effect. CONCLUSION: There is a need for efficient, ongoing screening of depressive and PTSD symptomatology in trauma exposed high risk groups so that early psychological supportive interventions can be offered.

Background: Trauma exposure prevalence and consequent post-traumatic stress disorder among South African adolescents are significant. Sleep disturbances are among the most frequently reported difficulties faced by those dealing with PTSD. The current study examined the feasibility and preliminary efficacy of the South African Adolescence Group Sleep Intervention on PTSD symptom severity and sleep disturbance.Method: Sixty-one adolescents with PTSD diagnoses and sleep disturbance were randomly assigned (1:1) to one individual and four group sessions of a sleep intervention (SAASI) or a control group. Participants completed the Child PTSD symptom scale for DSM5 (CPSS-5) and the Pittsburgh Sleep Quality Index (PSQI) among other sleep and psychiatric measures. The trial was registered on the Pan African Trial Registry (PACTR202208559723690).Results: There was a significant but similar decrease in PSQI scores in both groups over time indicating no overall intervention effect (Wald test = -2.18, p = .029), mean slope = -0.2 (95% CI: -0.37 to -0.02) (p = .583). On the CPSS-5, interaction between groups was also not significant (p = .291). Despite this overall finding, the mean difference in CPSS-SR-5 scores increased over time, with the difference between groups post-treatment -9.10 (95%CI: -18.00 to -0.21), p = .045 and the 1-month follow-up contrast - 11.22 (95%CI: -22.43 to -0.03), p = .049 suggesting that PTSD symptom severity decreased more in the intervention group than the control group. The dropout rate was higher than expected for both the intervention (n = 10; 32%) and control (n = 8; 26.7%) groups. Dropout were mostly school commitments or travel related.Conclusions: Early findings suggest a trend towards dual improvement in sleep quality and PTSD symptom severity in adolescents with a sleep disturbance and PTSD receiving a group sleep intervention (SAASI). Further investigation in a properly powered RCT with detailed retention planning is indicated.
A four-week group sleep intervention seems feasible in adolescents with PTSD and sleep disturbances in a low-resource South African setting.Utilising less specialised mental health resources such as nurses and counsellors in intervention delivery was feasible and effective.Preliminary results are promising and support further research to establish the efficacy of the intervention.

Routine HIV counseling and testing (RCT) is a necessary first step in accessing health care for persons who may test HIV-positive. Despite the availability of RCT in many South African settings, uptake has often been low. We sought to determine whether the main components of the Health Belief Model (HBM), namely perceived susceptibility, perceived severity, perceived benefits and perceived barriers could predict acceptance of RCT, and whether cues to action predicted uptake of RCT. A sample of 1 113 students at a large South African university completed a battery of instruments measuring acceptability of RCT, previous uptake of HIV testing, and the various HBM variables. Regression analysis showed that perceived susceptibility to HIV, perceived severity of HIV, perceived benefits of RCT, and perceived barriers to RCT explained 25.1% of the variance in acceptance of RCT. The findings of the study are located in the context of existing literature on RCT.
RESUMO
Sexual offending is a global problem but is particularly prevalent on the African continent and in South Africa. Childhood experiences related to abuse, alcohol use, and criminal activities in the household and community has been associated with an increased risk for violence perpetration in adulthood. Less is known about sexual violence perpetration, especially in the South African context. In this study, the experiences of incarcerated male perpetrators of rape in South Africa are investigated along with the collective social context and individual childhood experiences that potentially contribute to rape perpetration. Eighteen male perpetrators of rape who were inmates at Westville Correctional Services in KwaZulu Natal, South Africa, were interviewed. The semi-structured in-depth qualitative interviews were transcribed, coded and annotated using an interpretive paradigm and thematic analysis approach. Five main themes emerged from the research and included (1) childhood trauma and adverse events, e.g., an absent father, being raised without parents, exposure to criminal or violent behavior, physical abuse, sexual abuse and poverty, (2) understanding rape, e.g., rape as sex by force and without consent, rape as a violent act, rape as sex with a minor, myths about rape (3) substance abuse, e.g., history of alcohol and drug use, and intoxication during rape perpetration, (4) gender roles and avoiding responsibility, e.g., victim blaming, rape as male prerogative, transactional sex, being framed or set-up, ignoring an ancestral call and (5) recidivism. The findings revealed that all rape perpetrators were exposed to at least one childhood trauma type. Family and community violence and criminality was common. Most participants avoided taking responsibility for their actions and blamed the victim and recidivism/prior convictions were often reported. The findings demonstrate the complex personality dynamic involved in the cycle of abuse and the evolution of criminal behavior, starting as a victim and ending as a perpetrator. The findings also highlight the need for interventions aimed at reducing childhood trauma exposure and improving the social and relational context of those at risk for childhood neglect and abuse.
RESUMO
INTRODUCTION: The prevalence of posttraumatic stress disorder (PTSD) in rape survivors is considerably higher than the prevalence in non-sexual trauma survivors. Few studies have investigated risk and protective factors in survivors early-after-rape in a prospective longitudinal design. METHODS: In a sample of 639 rape-exposed women who were assessed within 20 days of rape and over 6 months, baseline data were used to predict PTSD symptom severity scores up to 6 months post-rape. RESULTS: The incidence of PTSD at 3 months was 48.5% and the cumulative incidence at 6 months post-rape was 54.8%. Baseline experience of rape stigma (guilt, shame, self-blame, social devaluation and discredit) and depression were significant predictors of PTSD symptom scores over time, in mixed linear regression models. Higher levels of depression and rape stigma were associated with higher PTSD scores. Assault-related factors were not associated with PTSD scores. LIMITATIONS: We could not measure PTSD symptom trajectories in all rape survivors, some of who may be at greater risk for PTSD e.g. non-disclosing rape survivors, those who declined participation and those who were extremely distressed at the time of recruitment. CONCLUSION: Addressing internalised and externalised stigma and resultant mental health effects on women who present to rape clinics may reduce the long-term adverse effects of rape on mental health outcomes, such as PTSD. Rape survivors who present with high levels of depression soon after a rape should be carefully monitored and appropriately treated in order to reduce PTSD severity.

BACKGROUND: In low- and middle-income countries, there is a high prevalence of post-partum depression and it is often associated with HIV status. Maternal depression negatively affects mothering and can lead to social withdrawal in infants. Maternal depression and infant social withdrawal can have deleterious long-term effects on children's behaviour and neurodevelopmental trajectories. AIM: To investigate whether maternal depression and infant social withdrawal at 10-12 months post-partum were significant predictors of child behaviour and development at 42 months. METHOD: Seventy-four mother-infant dyads living with HIV were followed in a prospective, longitudinal design. Mothers were assessed for depression using the Center for Epidemiologic Studies Depression scale (CES-D). Infant social withdrawal was assessed by the modified Alarm Distress Baby Scale (m-ADBB), and development and behaviour were evaluated by the Griffiths Mental Development Scales (GMDS) and the Child Behavior Checklist (CBCL), respectively. RESULTS: Maternal depression explained 4.8% of the variance in child behaviour (ß = 0.98, t = 2.05, p < 0.05) and 10.3% of the variance in development (ß = -0.30, t = -2.66, p < 0.05). Infant social withdrawal was not a significant predictor of behaviour (ß = 3.27, t = 1.36, p = 0.18), but it did uniquely explain 7% of the variance in development (ß = -1.32, t = -2.48, p < 0.05). CONCLUSION: In the context of HIV, screening for maternal depression and the quality of mother-infant interactions are important (especially in the 1st year post-partum), given the significant long-term impact they have on behaviour and neurodevelopment.

Both specific forms of violence and polyvictimization have been associated with an increased risk for negative mental health outcomes in youth. Despite evidence of gender differences in trauma experience and impact, gender patterns in the comparative contribution of specific violence exposures versus polyvictimization to mental health outcomes have seldom been explored. The few existing studies have all been conducted in high-income countries, while there is a dearth of research from lower and middle-income countries. This study examined the contribution of witnessed and direct community violence, domestic violence, sexual abuse, and different levels of polyvictimization to the severity of posttraumatic stress disorder (PTSD) and depression in a clinic sample of children and adolescents (n = 310) in South Africa. Although polyvictimization rates were high across both genders, polyvictimization posed differential risks for boys and girls. For girls, higher levels of polyvictimization, but not individual violence types, predicted both PTSD and depression severity. For boys, polyvictimization did not predict PTSD or depression severity. Higher levels of victimization in the community predicted PTSD severity among boys, while no forms of violence predicted depression. The findings confirm the value of examining gender patterns in the risk for posttraumatic sequelae posed by exposure to specific and cumulative forms of violence. Implications for interventions with youth in high-violence contexts such as South Africa are considered.

Rape is associated with a high risk for posttraumatic stress disorder (PTSD). DNA methylation changes may confer risk or protection for PTSD following rape by regulating the expression of genes implicated in pathways affected by PTSD. We aimed to: (1) identify epigenome-wide differences in methylation profiles between rape-exposed women with and without PTSD at 3-months post-rape, in a demographically and ethnically similar group, drawn from a low-income setting; (2) validate and replicate the findings of the epigenome-wide analysis in selected genes (BRSK2 and ADCYAP1); and (3) investigate baseline and longitudinal changes in BRSK2 and ADCYAP1 methylation over six months in relation to change in PTSD symptom scores over 6 months, in the combined discovery/validation and replication samples (n = 96). Rape-exposed women (n = 852) were recruited from rape clinics in the Rape Impact Cohort Evaluation (RICE) umbrella study. Epigenome-wide differentially methylated CpG sites between rape-exposed women with (n = 24) and without (n = 24) PTSD at 3-months post-rape were investigated using the Illumina EPIC BeadChip in a discovery cohort (n = 48). Validation (n = 47) and replication (n = 49) of BRSK2 and ADCYAP1 methylation findings were investigated using EpiTYPER technology. Longitudinal change in BRSK2 and ADCYAP1 was also investigated using EpiTYPER technology in the combined sample (n = 96). In the discovery sample, after adjustment for multiple comparisons, one differentially methylated CpG site (chr10: 61385771/ cg01700569, p = 0.049) and thirty-four differentially methylated regions were associated with PTSD status at 3-months post-rape. Decreased BRSK2 and ADCYAP1 methylation at 3-months and 6-months post-rape were associated with increased PTSD scores at the same time points, but these findings did not remain significant in adjusted models. In conclusion, decreased methylation of BRSK2 may result in abnormal neuronal polarization, synaptic development, vesicle formation, and disrupted neurotransmission in individuals with PTSD. PTSD symptoms may also be mediated by differential methylation of the ADCYAP1 gene which is involved in stress regulation. Replication of these findings is required to determine whether ADCYAP1 and BRSK2 are biomarkers of PTSD and potential therapeutic targets.

Objectives: Multiple, chronic and repeated trauma exposure in childhood is associated with adverse mental health outcomes in adulthood. In this paper we synthesise the literature on epigenetic modifications in childhood trauma (CT) and the mediating effects of differential epigenetic mechanisms on the association between CT and the later onset of psychiatric disorders.Methods: We reviewed the literature up to March 2018 in four databases: PubMed, Web of Science, EBSCOhost and SCOPUS. Non-human studies were excluded. All studies investigating CT exposure both in healthy adults (18 years and older) and adults with psychiatric disorders were included.Results: Thirty-six publications were included. For mood disorders, methylation of the glucocorticoid receptor NR3C1 gene, specifically at the NGFI-A binding site in exon 1F, and correlation with CT was a robust finding. Several studies documented differential methylation of SLC6A4, BDNF, OXTR and FKBP5 in association with CT. Common pathways identified include neuronal functioning and maintenance, immune and inflammatory processes, chromatin and histone modification, and transcription factor binding.Conclusions: A variety of epigenetic mediators that lie on a common pathway between CT and psychiatric disorders have been identified, although longitudinal studies and consistency in methodological approach are needed to disentangle cause and effect associations.

South African adolescents are exposed to high levels of violence and trauma, including community violence, abuse, and neglect. Violence and trauma are associated with negative mental health outcomes, including posttraumatic stress disorder (PTSD) and depression. Demographic characteristics, additional exposure to trauma, community violence, and types of childhood abuse and neglect may place adolescents at greater risk of developing PTSD. This study aimed to first assess the weighted contribution of demographic factors, trauma load, community violence, and types of abuse and neglect in predicting PTSD symptom severity. Second, we aimed to determine group differences in demographic factors, trauma load, community violence, and types of abuse and neglect among participants with no disorder, PTSD only, PTSD and depression, and depression only. Participants were 215 adolescents identified with emotional and/or behavioral problems and referred to an adolescent trauma clinic from schools in the Western Cape region of South Africa. Clinical assessments were undertaken to assess community violence exposure; physical, sexual, and emotional abuse; physical and emotional neglect; and a clinical diagnosis of PTSD and comorbidity. Trauma-exposed adolescents with PTSD and depression reported significantly higher levels of emotional abuse and community violence exposure in comparison with trauma-exposed adolescents without a disorder. Emotional abuse, community violence exposure, and female gender were significant predictors of PTSD in regression analysis. These findings underscore the contribution of different types of trauma in the development of PTSD. Interventions focused on preventing trauma, PTSD, and depression should be multifaceted and be targeted at various levels, for example, individual/interpersonal level (reduce abuse in the household and immediate environment) and community/societal level (reduce crime rates in communities and strengthen conviction policies). Traumatized youth should routinely be screened for a history of abuse and particularly exposure to community violence, given their strong association with PTSD.

OBJECTIVES: Neurocognitive impairments are commonly observed in adults suffering from posttraumatic stress disorder (PTSD). The picture is less clear in adolescents. Childhood sexual abuse (CSA) may have an independent influence on neuropsychological test performance and provide partial explanatory power of the inconsistent findings. We hypothesized that adolescents with PTSD who have also suffered sexual abuse would have most pronounced deficits on neurocognitive testing. METHODS: In a cross-sectional design, 105 traumatized South African adolescents, of whom 52 fulfilled criteria of PTSD and 34 reported CSA, were studied. A comprehensive neurocognitive battery including tests of memory, executive functioning, and language was used to analyze the associations of neurocognitive impairments with PTSD and CSA. RESULTS: Adolescents reporting CSA manifested impairments in proactive and retroactive interference tasks on the Rey Auditory Verbal Learning test and in the copy condition of the Rey Osterrieth figure test, indicating deficits in attention and working memory. Against our hypothesis, no independent effects of PTSD were found on neurocognitive performance. Results were independent of comorbid psychiatric diagnoses. CONCLUSIONS: Sexual abuse seems to have an independent influence on attention and working memory. This could be an early sign of hippocampal impairment.

Women survivors of rape are at an increased risk for posttraumatic stress disorder (PTSD). Traumatic dissociation has been identified as a precursor of PTSD. This study assessed the predictive potential of traumatic dissociation in PTSD and depression development.The study followed a longitudinal, prospective design. Ninety-seven female rape survivors were recruited from 2 clinics in Cape Town, South Africa. Clinical interviews and symptom status assessments of the participants were completed to measure dissociation, childhood traumas, resilience, depression, and PTSD.Traumatic dissociation was a significant predictor of PTSD and depression. The linear combination of prior dissociation, current dissociation, and resilience significantly explained 20.7% of the variance in PTSD. Dissociation mediated the relationship between resilience and PTSD.As traumatic dissociation significantly predicts PTSD, its early identification and management may reduce the risk of developing PTSD. Interventions focused on promoting resilience may also be successful in reducing the risk of dissociation following rape.

OBJECTIVES: HIV and psychiatric disorders are prevalent and often concurrent. Childbearing women are at an increased risk for both HIV and psychiatric disorders, specifically depression and post-traumatic stress disorder (PTSD). Poor mental health in the peripartum period has adverse effects on infant development and behaviour. Few studies have investigated the relationship between maternal PTSD and child behaviour outcomes in an HIV vertically infected sample. The aim of this study was to investigate whether maternal postpartum trauma exposure and PTSD were risk factors for child behaviour problems. In addition, maternal depression, alcohol abuse and functional disability were explored as cofactors. SETTING: The study was conducted in Cape Town, South Africa. PARTICIPANTS: 70 mother-child dyads infected with HIV were selected from a group of participants recruited from community health centres. DESIGN: The study followed a longitudinal design. Five measures were used to assess maternal trauma exposure, PTSD, depression, alcohol abuse and functional disability at 12 months postpartum: Life Events Checklist (LEC), Harvard Trauma Scale (HTS), Alcohol Use Disorders Identification Test (AUDIT), Center for Epidemiological Studies Depression (CESD) Scale and the Sheehan Disability Scale (SDS). Child behaviour was assessed at 42 months with the Child Behaviour Checklist (CBCL). RESULTS: The rate of maternal disorder was high with 50% scoring above the cut-off for depression, 22.9% for PTSD and 7% for alcohol abuse. Half of the children scored within the clinical range for problematic behaviour. Children of mothers with depression were significantly more likely to display total behaviour problems than children of mothers without depression. Maternal PTSD had the greatest explanatory power for child behaviour problems, although it did not significantly predict child outcomes. CONCLUSIONS: This study highlights the importance of identifying and managing maternal PTSD and depression in mothers of children infected with HIV. The relationship between maternal PTSD and child behaviour warrants further investigation.
RESUMO
Background: The effectiveness of antiretroviral therapy (ART) and the importance of adherence to treatment regimens are widely known. Yet; suboptimal adherence to ART and retention in care of patients still persists and; by many accounts; is fairly widespread. The aim of this study was to identify the structural barriers that influenced adherence among patients who were enrolled in the national ART programme in South Africa.Method: In this qualitative study; semi-structured interviews were conducted with a sample of 10 patients receiving ART at a public hospital in South Africa.Results: The results of the interviews were categorised according to poverty-related; institution-related and social barriers to clinic attendance and pill-taking; which collectively formed the structural barriers to adherence. The chief structural barriers to clinic attendance were time away from work; transport expenses; long waiting times and negative experiences with clinic staff. The chief barriers to pill-taking were food insecurity; stigma and discrimination.Conclusion: The barriers to adherence are discussed. Attention is called to the extraindividual factors that influenced ART adherence. We conclude that contextual factors; such as a healthcare-enabling environment; might play an important role in influencing healthcare-promoting behaviour among patients
