This study investigates personality-driven Work-Life Integration (WLI) as a mediating mechanism between modern lifestyle risk factors for non-communicable diseases (NCDs) and long-term employee health outcomes among servicesector employees in Indore's multinational organisations. Drawing on Conservation of Resources (COR) theory and the Big Five personality framework, a moderated mediation model is tested in which personality traits—particularly Conscientiousness and Neuroticism—shape the degree to which exposure to lifestyle risk factors (sedentary behaviour, poor dietary patterns, sleep disruption, digital overload, and substance-use risk) translates into impaired WLI, which in turn predicts deteriorated health. Organisational support for WLI (W₁), industry sector (W₂), marital status (W₃), and designation level (W₄) function as contextual moderators. Cross-sectional survey data from N = 962 employees across IT/Technology (n = 529), Banking/Finance (n = 349), and Healthcare/Hospitality (n = 84) sectors were analysed using OLS moderated regression, moderated mediation (Sobel test with 5,000-iteration bootstrap), oneway ANOVA, and interaction slope analysis. The Lifestyle Risk Composite (LRC) significantly predicted WLI deterioration (β = .312, p < .001), with Conscientiousness buffering this pathway (βᵢₙₜ = −.082, p < .001) and Neuroticism amplifying it (βᵢₙₜ = +.071, p = .001). WLI fully and partially mediated the LRC–health relationship (indirect effect = .166, 95% CI [.124, .208]; Sobel Z = 7.84, p < .001). The full moderated mediation model explained R² = .534 of variance in the composite Health Index. Sector-level ANOVAs revealed IT/Technology employees carried the highest lifestyle risk exposure (M = 3.13) while Healthcare/Hospitality employees showed the highest WLI (M = 3.04). A striking designation escalation was observed: the WLI–health correlation strengthened from r = −.193 at entry level to r = −.813 at executive level. Findings underscore the primacy of personality-driven behavioural pathways in linking occupational lifestyle exposures to NCD-relevant health outcomes, with strong implications for targeted organisational wellness interventions. .
