Abdominal obesity and metabolic syndrome in South Asians: prevention and management

Introduction: The prevalence of metabolic syndrome (MetS) and abdominal obesity are escalating in South Asian countries. It is well established that MetS is associated with increased risk for both Type 2 diabetes mellitus and cardiovascular diseases. South Asians have an increased risk of MetS due to a variety of factors including unhealthy lifestyle and their unique body composition. Areas covered: In this review, we discuss the prevalence, associated risk factors, and evidence-based preventive and curative strategies for MetS and abdominal obesity in South Asians. A literature search through PubMed (R), Web of Science (R), and Scopus (R) was performed for studies published before 31(st) April 2021. A combination of the following keywords was used with the names of the individual South Asian countries: 'metabolic syndrome,' 'syndrome X,' 'abdominal obesity,' 'central obesity,' 'visceral obesity,' 'prevention,' and 'management.' Expert opinion: According to current evidence, MetS and abdominal obesity are highly prevalent among South Asians. Several risk factors, such as lifestyle, socio-demography, cultural, and body composition, are associated with MetS. Limited research shows culturally tailored lifestyle interventions are effective in preventing and managing MetS and abdominal obesity among South Asians.
