Loneliness has emerged as a critical social determinant of health with far-reaching implications for physical health, mental well-being, social inclusion, and economic productivity. This review examines the conceptual foundations, measurement approaches, and policy responses to loneliness, drawing on multidisciplinary evidence from sociology, psychology, public health, and public policy. It explores loneliness as a subjective experience distinct from social isolation while highlighting its association with adverse outcomes such as depression, cardiovascular disease, reduced quality of life, increased healthcare utilization, and premature mortality. The review synthesizes contemporary approaches to measuring loneliness, including psychological scales, social and behavioral indicators, objective and subjective assessments, and emerging digital and big-data methods, emphasizing the importance of validity, reliability, and cultural sensitivity in measurement frameworks. It further analyzes the policy relevance of loneliness across health, social, and economic sectors, demonstrating how national governments and international organizations increasingly recognize loneliness as a public policy priority. Evidence from high-income and lowand middle-income countries illustrates that the prevalence, determinants, and policy responses to loneliness are shaped by socioeconomic inequalities, demographic characteristics, geographic contexts, and cultural environments. The review also evaluates intervention strategies, including community-based initiatives, social prescribing, digital technologies, universal and targeted interventions, and cross-sectoral policy frameworks aimed at strengthening social connectedness. Despite growing policy attention, significant challenges remain regarding standardized measurement, integrated data systems, ethical data collection, and the long-term evaluation of interventions. The review concludes that reducing loneliness requires coordinated, evidence-based, and culturally responsive policies that integrate health, social protection, urban planning, education, and community development to promote social inclusion, resilience, and population well-being.
