Poverty and common mental disorders in low and middle income countries: a systematic review.

In spite of high levels of poverty in low and middle income countries (LMIC), and the high burden posed by common mental disorders (CMD), it is only in the last two decades that research has emerged that empirically addresses the relationship between poverty and CMD in these countries. We conducted a systematic review of the epidemiological literature in LMIC, with the aim of examining this relationship. Of 115 studies that were reviewed, most reported positive associations between a range of poverty indicators and CMD. In community-based studies, 73% and 79% of studies reported positive associations between a variety of poverty measures and CMD, 19% and 15% reported null associations and 8% and 6% reported negative associations, using bivariate and multivariate analyses respectively. However, closer examination of specific poverty dimensions revealed a complex picture, in which there was substantial variation between these dimensions. While variables such as education, food insecurity, housing, social class, socio-economic status and financial stress exhibit a relatively consistent and strong association with CMD, others such as income, employment and particularly consumption are more equivocal. There are several measurement and population factors that may explain variation in the strength of the relationship between poverty and CMD. By presenting a systematic review of the literature, this paper attempts to shift the debate from questions about whether poverty is associated with CMD in LMIC, to questions about which particular dimensions of poverty carry the strongest (or weakest) association. The relatively consistent association between CMD and a variety of poverty dimensions in LMIC serves to strengthen the case for the inclusion of mental health on the agenda of development agencies and in international targets such as the millenium development goals.

Scaling up mHealth: where is the evidence?

Mark Tomlinson and colleagues question whether there is sufficient evidence on implementation and effectiveness to match the wide enthusiasm for mHealth interventions, and propose a global strategy to determine needed evidence to support mHealth scale-up.

Improving quality of mother-infant relationship and infant attachment in socioeconomically deprived community in South Africa: randomised controlled trial.

Objective To assess the efficacy of an intervention designed to improve the mother-infant relationship and security of infant attachment in a South African peri-urban settlement with marked adverse socioeconomic circumstances. Design Randomised controlled trial. Setting Khayelitsha, a peri-urban settlement in South Africa. Participants 449 pregnant women. Interventions The intervention was delivered from late pregnancy and for six months postpartum. Women were visited in their homes by previously untrained lay community workers who provided support and guidance in parenting. The purpose of the intervention was to promote sensitive and responsive parenting and secure infant attachment to the mother. Women in the control group received no therapeutic input from the research team. Main outcome measures Primary outcomes: quality of mother-infant interactions at six and 12 months postpartum; infant attachment security at 18 months. Secondary outcome: maternal depression at six and 12 months. Results The intervention was associated with significant benefit to the mother-infant relationship. At both six and 12 months, compared with control mothers, mothers in the intervention group were significantly more sensitive (6 months: mean difference=0.77 (SD 0.37), t=2.10, P<0.05, d=0.24; 12 months: mean difference=0.42 (0.18), t=−2.04 , P<0.05, d=0.26) and less intrusive (6 months: mean difference=0.68 (0.36), t=2.28, P<0.05, d=0.26; 12 months: mean difference=−1.76 (0.86), t=2.28 , P<0.05, d=0.24) in their interactions with their infants. The intervention was also associated with a higher rate of secure infant attachments at 18 months (116/156 (74%) v 102/162 (63%); Wald=4.74, odds ratio=1.70, P<0.05). Although the prevalence of maternal depressive disorder was not significantly reduced, the intervention had a benefit in terms of maternal depressed mood at six months (z=2.05, P=0.04) on the Edinburgh postnatal depression scale). Conclusions The intervention, delivered by local lay women, had a significant positive impact on the quality of the mother-infant relationship and on security of infant attachment, factors known to predict favourable child development. If these effects persist, and if they are replicated, this intervention holds considerable promise for use in the developing world. Trial registration Current Controlled Trials ISRCTN25664149.

Culture and mental health - A Southern African view

This is a long awaited text within the field of mental health in South Africa, as there is very little written about culture and mental health within the specific context of South Africa. This book is very useful for students in any field of mental health like psychology, nursing, social work and medicine. *Please note: This is a reduced version of the abstract.

Setting priorities for global mental health research

OBJECTIVE To set investment priorities in global mental health research and to propose a more rational use of funds in this under-resourced and under-investigated area. METHODS Members of the Lancet Mental Health Group systematically listed and scored research investment options on four broad classes of disorders: schizophrenia and other major psychotic disorders, major depressive disorder and other common mental disorders, alcohol abuse and other substance abuse disorders, and the broad class of child and adolescent mental disorders. Using the priority-setting approach of the Child Health and Nutrition Research Initiative, the group listed various research questions and evaluated them using the criteria of answerability, effectiveness, deliverability, equity and potential impact on persisting burden of mental health disorders. Scores were then weighted according to the system of values expressed by a larger group of stakeholders. FINDINGS The research questions that scored highest were related to health policy and systems research, where and how to deliver existing cost-effective interventions in a low-resource context, and epidemiological research on the broad categories of child and adolescent mental disorders or those pertaining to alcohol and drug abuse questions. The questions that scored lowest related to the development of new interventions and new drugs or pharmacological agents, vaccines or other technologies. CONCLUSION In the context of global mental health and with a time frame of the next 10 years, it would be best to fill critical knowledge gaps by investing in research into health policy and systems, epidemiology and improved delivery of cost-effective interventions.

Structural barriers to ART adherence in Southern Africa: Challenges and potential ways forward

Abstract Structural barriers to antiretroviral therapy (ART) adherence are economic, institutional, political and cultural factors, that collectively influence the extent to which persons living with HIV follow their medication regimens. We identify three sets of structural barriers to ART adherence that are salient in Southern Africa: poverty-related, institutional, and political and cultural. Examples of poverty-related barriers are competing demands in the context of resource-constrained settings, the lack of transport infrastructure, food insecurity, the role of disability grants and poor social support. Examples of institutional factors are logistical barriers, overburdened health care facilities, limited access to mental health services and difficulties in ensuring adequate counselling. Examples of political and cultural barriers are controversies in the provision of treatment for AIDS, migration, traditional beliefs about HIV and AIDS, poor health literacy and gender inequalities. In forging a way forward, we identify ways in which individuals, communities and health care systems may overcome some of these structural barriers. Finally, we make recommendations for further research on structural barriers to ART adherence. In all likelihood, enhancing adherence to ART requires the efforts of a variety of disciplines, including public health, psychology, anthropology, sociology and medicine.

Paediatric HIV/AIDS disclosure: towards a developmental and process-oriented approach

Abstract As antiretroviral therapy becomes more widely available in low-resource settings and children with HIV/AIDS live for longer periods, disclosure of HIV diagnosis to infected children is becoming increasingly important. This article reviews the current literature on HIV-related disclosure in light of theories of cognitive development, and argues for the adoption of a process-oriented approach to discussing HIV with infected children. Disclosure presents unique challenges to healthcare workers and caregivers of children with HIV/AIDS that include controlling the flow of information about the childs HIV status to him/her and deciding on what is in his/her best interest. Health care workers’ and caregivers’ views regarding disclosure to children may often be contradictory, with healthcare workers likely to support disclosing the diagnosis of HIV/AIDS to children and caregivers more reluctant to discuss the disease with them. There is a clear need for practical interventions to support paediatric HIV disclosure which provide children with age-appropriate information about the disease.

Research priorities for health of people with disabilities: an expert opinion exercise

International evidence shows that people with disabilities have many unmet health and rehabilitation needs, face barriers in accessing mainstream health-care services, and consequently have poor health. Inadequate specific information is available about the prevalence and patterns of health conditions of people with disabilities, effective interventions, and policy-relevant research about what works to improve health and functioning of people with disabilities. In view of the urgency of the issues at stake and scarcity of resources, research contributing to improvement of health of people with disabilities needs to be prioritised. We invited 82 stakeholders to list and score research options, with the priority-setting method of the Child Health and Nutrition Research Initiative. 83 research questions were assessed for answerability, applicability, sensitivity, support within the context, and equity. The leading research priority was identification of barriers that people with disabilities have in accessing health services at different levels, and finding the best possible strategies to integrate their needs into primary health-care systems and ensure local delivery. Results showed that addressing specific impairments is secondary to ensuring that health systems provide adequately for all people with disabilities. Our findings are a call for urgent attention to the issue of access to appropriate health care for people with disabilities, especially in low-income and middle-income countries.

Anorexia nervosa as a culture-bound syndrome

Current psychological theories on anorexia nervosa share a common assumption that symptoms of the condition are related to cultural factors. The present article argues that the disorder can be fruitfully understood in the context of one definition of culture-bound syndromes. By way of introduction two contrasting models of the cross-cultural study of psycho-pathology are outlined in order to contextualize the argument in a particular paradigm. Anorexia nervosa is shown to fit the criteria of the Cassidy/Ritenbaugh definition of culture-bound syndromes, and the definition is shown to have some use in elucidating issues. Implications for a more flexible approach to theory development and therapeutic practice are discussed, and suggestions are made for further work demonstrating the negotiated nature of the disorder.

Point of care in your pocket: a research agenda for the field of m-health

A frontier mindset fosters real and rapid innovation in mobile health. This fast, iterative approach should not be lost, especially given the speed with which mobile and wireless technologies evolve, but caution is warranted. Although well on track towards attaining its goal of reaching 1 million mothers by 2012, Text4Baby, a free mobile text service sponsored by Johnson & Johnson in the United States of America, is a case in point.
