Household energy is increasingly vital for maintaining good health. Unaffordable and inadequate household energy presents adverse consequences that are amplified by poverty and a changing climate. To date, the connections between energy, socioeconomic disadvantage, and well-being are generally underappreciated, and household energy connection with climate change is under-researched. Building on the energy insecurity framework, this review explores literature related to household energy, poverty, and health in order to highlight the disproportionate burdens borne by vulnerable populations in adequately meeting household energy needs. This paper is based on a comprehensive review of books, peer-reviewed articles, and reports published between 1990 and 2019, identified via databases including JSTOR and PubMed. A total of 406 publications were selected as having potential for full review, 203 received full review, and 162 were included in this paper on the basis of set inclusion criteria. From the literature review, we created an original heuristic model that describes energy insecurity as either acute or chronic, and we further explore the mediators and pathways that link energy insecurity to health. In the discussion, we posit that the extant literature does not sufficiently consider that vulnerable communities often experience energy insecurity bundled with other hardships. We also discuss energy, poverty, and health through the lens of climate change, making the criticism that most research on household energy does not consider climate change. This evidence is important for enhancing research in this field and developing programmatic and policy interventions as they pertain to energy access, affordability, and health, with special emphasis on vulnerable populations, climate change, and social inequality.

Background: Latin America, and Chile in particular, has a rich tradition of community mental health services and programs. However, in vivo community-based psychosocial interventions, especially those with a recovery-oriented approach, remain scarce in the region. Between 2014 and 20l5, a Critical Time Intervention-Task Shifting project (CTI-TS) was implemented in Santiago, Chile, as part of a larger pilot randomized control trial. CTI is a time-limited intervention delivered at a critical-time to users, is organized by phases, focuses on specific objectives and decreases in intensity over time. CTI-TS, which combines both the task-shifting strategy and the use of peers, introduces a novel approach to community mental health care that has not yet been tried in Chile. Aims: We aim to evaluate the feasibility, acceptability and applicability of such a community-based psychosocial intervention in urban settings in Latin America – specifically, in Santiago (Chile) from a user perspective. Method: We analyzed 15 in-depth interviews (n = 15) with service users who participated in the intervention about their perceptions and experiences with CTI-TS through thematic analysis. Results: Three themes were revealed. The first was related to the structural characteristics of CTI-TS, especially regarding the timing, duration and phasic nature of the intervention. The second pertained to the acceptability of the in vivo community-based approach. The third theme dealt with the task-shifting aspect, that is, users’ perceptions of the peer support workers and the community mental health workers. Conclusions: CTI-TS was generally acceptable in this Latin American context. Users’ perspectives pointed to the need to make adjustments to some of the structural characteristics of the CTI model and to combine this type of intervention with others that can address stigma. Thus, future adaptations of CTI-TS or similar psychosocial interventions in Latin American contexts are feasible and can enhance community mental health in the region.
