The Politics of Behavioural Change for Environmental Health Promotion in Developing Countries

Health behaviors related to endocrine-disrupting chemicals and the associated factors of adolescent Korean girls

In this cross-sectional study, we examined the relationships among knowledge about endocrine-disrupting chemicals (EDCs), recognition of EDCs-related female reproductive illnesses, concern for the environment, perceived susceptibility to EDCs-related diseases, self- appraisal of exposure to EDCs, and health behaviors related to EDCs in adolescent Korean girls. A convenience sample of 218 girls was recruited during July and August 2015 from middle and high schools located in a city in Korea. The self-administered questionnaire incorporated four characteristics of the participants, five related factors, and a dependent variable of health behaviors. Four of the factors explained 20.4 percent of variance in health behaviors, and after controlling covariates, concern for the environment and self-appraisal of exposure to EDCs were still significant factors explaining 29.0 percent of the variance in health behaviors. However, for one factor, knowledge about EDCs, no independent contribution to health behaviors was observed. The findings indicated that education for young women should focus on enhancing their interests in the environment and awareness of environmental hazards. Further, clear and reliable guidelines to protect young women from the exposure to EDCs should be provided to adolescent girls.

Child lead poisoning in South Africa: implications for psychological research

Lead is a toxic heavy metal that is associated with lowered intelligence quotient scores, behavioural problems, and physical health impairments in children. Current consensus is that there is no safe level of child lead exposure and that even low doses of lead can have negative effects. Several reviews conducted in South Africa have revealed the sources and potential risk factors associated with child lead poisoning. However, no South African reviews have focused on the quality of studies focusing on child lead poisoning and psychological outcomes (intelligence, cognitive, and behavioural outcomes). This study reviews epidemiological studies of child lead poisoning with a particular focus on the association between child lead poisoning and psychological outcomes in South Africa over a 30-year time span (1986–2016). The review pays particular attention to study design, measurement, sampling, and confounding variables. Nine studies that measured child lead poisoning were included in the review. Just two of the nine studies (one cross-sectional and one follow-up) measured psychological outcomes and neither study adequately adjusted for confounding. In all studies, sampling was purposive and lead exposure indicators were suited to short-term acute exposure. There is, therefore, insufficient evidence to determine the magnitude of the association between child lead poisoning and psychological outcomes in South Africa. More rigorous epidemiological studies are needed to strengthen the evidence base. The article also highlights opportunities for psychological research in intervention studies and studies that are framed by an environmental justice agenda.

Critiques of health behaviour change programmes

Critics have raised concerns about health behaviour change programmes in the global South. However, there has been very little reflection about what those critiques are critical of and, in particular, what psychology has come to mean within those critiques. The aim of this article was threefold: to describe existing critiques of behaviour change programmes, to reflect on how psychology has been written into those critiques, and to determine what theoretical resources critiques overlook. This article identifies four types of critiques (efficacy, sociological, ethical, and governance) and argues that critiques tend be psychologised and miss important insights from resources related to discourse, gender, knowledge production, and resistance. It is hoped that this article will stimulate further debate about the role of psychology in behaviour change interventions in the global South.

Using behavior change to reduce child lead exposure in resource-poor settings: a formative study

The objective of this formative research was to explore the acceptability and feasibility of changing housekeeping behaviors as a low-cost approach that may reduce childhood lead exposure in Johannesburg, South Africa. Using the Trials of Improved Practices (TIPs) methodology, modified housekeeping behaviors were negotiated with participants who chose the behaviors they wanted to try and then performed them in their homes over 4 weeks. Researchers interviewed them at the end of the month to understand their experience of trying out the behaviors. The modified behaviors offered to each participant were as follows: cleaning window sills with detergent and water, cleaning window sills more frequently, mopping floors with two buckets (one with soapy water for washing and one with clean water for rinsing), mopping floors more frequently, dusting surfaces with detergent and water and dusting surfaces more frequently. Participants found cleaning window sills with soap and water and cleaning them more often the most acceptable and feasible of behavior modifications. Environmental samples showed a significant reduction in lead dust on window sills. These findings can assist in the development of acceptable and feasible medium-term interventions to reduce childhood lead exposure in resource-poor settings until more robust health policies are implemented.

[Promotion of environmental health: close up of two fields. The case of Mexico]

En México, al igual que en otras regiones del mundo, se presentan desafíos complejos en salud ambiental que requieren de nuevos enfoques integradores, participativos e interdisciplinarios. El propósito de este artículo es mostrar las ventajas que puede aportar el campo de la promoción de la salud al de la salud ambiental para afrontar estos desafíos. Se abordan de manera general y particularmente para el caso de México las principales características de los dos campos. Además se discuten algunas de las diferencias epistemológicas y metodológicas que dificultan el acercamiento de las dos áreas y la utilidad de un concepto o campo de promoción de la salud ambiental. Finalmente se propone un modelo conceptual que permite visualizar los principales elementos a tomar en cuenta para investigaciones o intervenciones en promoción de la salud ambiental. Y se dan ejemplos de acciones en promoción de la salud ambiental en México, usando el modelo planteado.

Pre-existing beliefs and expectations influence judgments of novel health information

The present study examined whether health information is judged differently depending on pre-existing beliefs and expectations. People's initial beliefs and expectations were assessed by a questionnaire about acupuncture and a trustworthiness and preference rating task of doctors' faces. Then, newspaper headlines about novel acupuncture treatment were shown and rated for their feasibility in a normal and framed condition. The judged feasibility of the newspaper headlines correlated strongly with initial beliefs about acupuncture in the normal condition, and with initial expectations towards a doctor's face in the framed condition. Thus, as suggested by Bayes Theorem, pre-existing beliefs and expectations influence judgments of novel health information.

Community ‘Participation’, Resistance and the Water Wars

Water is essential to human life, health and development. Prepaid water metres are a popular yet controversial approach to extending water services to the poor. They operate on an upfront payment system which automatically disconnects water if households do not have enough money to replenish supplies. While prepaid water metres have been criticised on a number of levels, this article focuses on the equally problematic discourses used to promote them amongst the poor. By drawing on a case study of a poor South African community's struggle against prepaid water metres, this article highlights how prepaid metres were promoted using psycho-education campaigns under the guise of ‘participation’. It also documents community resistance to the campaigns ending in a court battle that ruled in favour of communities’ right to sufficient water.
