Pesticides in Tanzania are extensively used for pest control in agriculture. Their usage and unsafe handling practices may potentially result in high farmer exposures and adverse health effects.

A human rights approach to health is critical to address growing global health inequalities. Three aspects of the nature of health as a right are relevant to shaping a human rights approach to health: (1) the indivisibility of civil and political rights, and socio-economic rights; (2) active agency by those vulnerable to human rights violations; and (3) the powerful normative role of human rights in establishing accountabiliy for protections and freedoms. Health professionals' practice, tpically governed by ethical codes, may benefit from human rights guidelines, particularly in situations of dual loyalty where clients' or communities' human rights are threatened Moreover, institutional accountability for protecting human rights is essential to avoid shifting responsibility solely onto the health professional Human rights approaches can include holding states and other parties accountable, developing policies and programs consistent with human rights, and facilitating redress for victims of violations of the right to health. However, underlying all models is the need to enable active social mobilization, without which legal approaches to rights lack sustainability and power. Evidence from South and Southern Africa has shown that different conceptions of what is meant by human rights impact substantially on state willingness and abiliy to meet constitutional obligations with regard to the right to health. New approaches to health polity development, which draw on the agency of vulnerable groups, link local struggles with their global context, and explicitly incorporate rights frameworks into public health planning are needed. Models that move away from individualizing conflict over rights between health professionals as disempowered duty bearers and patients as frustrated rights holders, toward more mutual approaches to shared rights objectives may be possible and are being actively pursued through the development of a learning network to realize the right to health in South Africa.

Aims and scope This editorial is an introduction to the papers making up the special issue on ’pesticide poisonings in low- and middle income countries’.

Informed consent is an ethical and legal requirement for research involving human participants. However, few studies have evaluated the process, particularly in Africa.

Late booking and infrequent antenatal care (ANC) are common but avoidable patient-related risk factors for maternal deaths in South Africa. The aim of the study was to examine the association of psychosocial factors with early initiation of ANC and adequate frequency of attendance of ANC clinics among women in an urban and rural location in South Africa. Data from a 2006 cross-sectional household survey of 363 women from the rural Western Cape and 466 women from urban Gauteng provinces of South Africa for risk of alcohol-exposed pregnancy were analysed. We examined associations between psychosocial variables (self-esteem, cultural influences, religiosity, social capital, social support, pregnancy desire (wanted versus unwanted pregnancy), partner characteristics and mental health) and both early ANC first visit (before 16 weeks) and adequate frequency of ANC visits (4 or more visits) for respondents’ last pregnancy. Overall prevalence among urban women of early ANC initiation was 46 % and 84 % for adequate ANC frequency. Overall prevalence among rural women of early ANC initiation was 45 % and 78 % for adequate ANC frequency. After adjusting for clustering, psychosocial factors associated with early ANC initiation in the urban site were being employed (OR 1.6; 95 % CI 1.0–2.5) and wanted pregnancy (OR 1.8; 95 % CI 1.1–3.0). For the rural site, early ANC initiation was significantly associated with being married (OR 1.93; 95 % CI 1.0–3.6) but inversely associated with high religiosity (OR 0.5; 95 % CI 0.3–0.8). Adequate frequency of ANC attendance in the rural site was associated with wanted pregnancy (OR 4.2; 95 % CI 1.9–9.3) and the father of the child being present in the respondent’s life (OR 3.0; 95 % CI 1.0–9.0) but inversely associated with having a previous miscarriage (OR 0.4; 95 % CI 0.2–0.8). There were no significant associations between adequate ANC attendance and the psychosocial factors in the urban site. The majority of women from both sites attended ANC frequently but less than 50 % initiated ANC before the recommended 16 weeks gestational age. Interventions to reduce prevalence of late ANC booking and inadequate ANC attendance should engage religious leaders, address unintended pregnancy through family planning education and involve male partners in women’s reproductive health.

Public health has multicultural origins. By the close of the nineteenth century, Schools of Public Health (SPHs) began to emerge in western countries in response to major contemporary public health challenges. The Flexner Report (1910) emphasized the centrality of preventive medicine, sanitation, and public health measures in health professional education. The Alma Ata Declaration on Primary Health Care (PHC) in 1978 was a critical milestone, especially for low and middle-income countries (LMICs), conceptualizing a close working relationship between PHC and public health measures. The Commission on Social Determinants of Health (2005–2008) strengthened the case for SPHs in LMICs as key stakeholders in efforts to reduce global health inequities. This scoping review groups text into public health challenges faced by LMICs and the role of SPHs in addressing these challenges. The challenges faced by LMICs include rapid urbanization, environmental degradation, unfair terms of global trade, limited capacity for equitable growth, mass displacements associated with conflicts and natural disasters, and universal health coverage. Poor governance and externally imposed donor policies and agendas, further strain the fragile health systems of LMICs faced with epidemiological transition. Moreover barriers to education and research imposed by limited resources, political and economic instability, and unbalanced partnerships additionally aggravate the crisis. To address these contextual challenges effectively, SPHs are offering broad based health professional education, conducting multidisciplinary population based research and fostering collaborative partnerships. SPHs are also looked upon as the key drivers to achieve sustainable development goals (SDGs). SPHs in LMICs can contribute to overcoming several public health challenges being faced by LMICs, including achieving SDGs. Most importantly they can develop cadres of competent and well-motivated public health professionals: educators, practitioners and researchers who ask questions that address fundamental health determinants, seek solutions as agents of change within their mandates, provide specific services and serve as advocates for multilevel partnerships. Funding support, human resources, and agency are unfortunately often limited or curtailed in LMICs, and this requires constructive collaboration between LMICs and counterpart institutions from high income countries.
