Background The potential contribution of local authorities to prevention and health promotion is well recognized. In France, since 2009, Local Health Contracts (LHCs) are mobilising Regional Health Agencies, local elected officials and stakeholders to intervene in 4 areas: health promotion, prevention, health care and social care. LHCs remain poorly documented policy instruments. MethodsAs part of the CLoterreS study, a multidimensional coding tool was developed and tested by two coders to explore the place of prevention and health promotion in LHCs. Its development was based on the WHO conceptual framework for action on the social determinants of health and the Self-assessment tool for the evaluation of essential public health operations in the WHO European Region. Preliminary results concern a random sample of 17 LHCs from as many French regions selected among the 165 LHCs signed between 2015 and March 2018. Results On average, the LHCs featured 26 action forms (AF) (min: 5; max: 56). In a LHC, the average proportion of AF addressing either the social determinants of health, living circumstances or other determinants targeted by health protection, promotion or primary prevention interventions (SDoH-HPP-P1) was 79% while 44% of the AF address secondary/tertiary prevention, social care or the organization of health care and services. Among the SDoH-HPP-P1 themes (double coding permitted): psychosocial life circumstances were addressed in the 17 LHCs and concerned, on average, 31% of their AF; material living circumstances were addressed to a lesser extent (16 LHCs, 13%); other key themes include environmental health (12, 14%), mental health (16, 12%), alcohol abuse (15, 11%), drug use (14, 11%), smoking (13, 9%), physical activity (13, 12%), healthy eating (12, 12%). Conclusions This work confirms that LHCs are instruments with prevention and health promotion at their core. Explanation of the differing investments in this area across our sample will be further explored. Key messages Local Health Contracts are promising instruments to address locally a broad range of health determinants. The CLoterreS analytical tool has proven effective in capturing multiple themes and shedding light on differences between Local Health Contracts’ action plans.
