Background We aimed to determine the prevalence of past-year health service use for mental health reasons in a French representative sample of adults overall and in those reporting suicidal ideation in the past year and assess the factors associated with health service use according Andersen's model of healthcare seeking behaviors. Methods Data were drawn from the 2017 Health Barometer survey a large computer-assisted telephone survey on a representative sample of the general population aged 18–75 years living in France (n = 25,319). Logistic regression analyses were used to study past-year health service use for mental health reasons as a function of predisposing, enabling and need factors. Analyses were stratified according to suicidal ideation and sex. Results Among individuals with suicidal ideation, 45.1 % of adults, 50.4 % of females and 37.6 % of males, reported past-year health service use for a mental health reason. Increased odds of health service use were observed regarding predisposing (female sex, younger age, higher education), enabling (income level), and need factors (prior suicide attempts, role impairment and major depression). Among males, the only significant factors included age 65–75 (aOR = 0.16, 95%CI = 0.03–0.84) and major depression (aOR = 2.79, 95%CI = 1.79–4.36). Limitations Self-reported service utilization. Cross-sectional survey. Conclusions In a country with a high level of medical coverage, further research is needed to identify sex-specific socio-demographic, economic and clinical differences in the use of different types of health services as well as perceived need for care, structural and attitudinal barriers to treatment.< Réduire
