Abstract [Objective]To explore the relationship between a family history of obesity and hypertriglyceridemic‐waist (HTWC) phenotype in adolescents .[Methods]A cross‐sectional study was conducted for 3 ,136 Han adoles‐cents aged 13~17 years in Qinhuangdao through stratified and cluster sampling .The HTWC phenotype was defined as serum triglyceride concentrations ≥1 .47 mmol/L and waist circumference ≥90th percentile for age and gender . Based on a family history of obesity ,they were divided into two groups of positive family history ( n =1169) and negative family history ( n =1967) .The triglyceride concentrations ,height ,weight and waist circumference were measured .And body mass index was calculated .[Results]Waist circumference and serum triglyceride were significant‐ly higher in adolescents with a family history of obesity than those in adolescents without a family history of obesity ( P<0 .05) .The prevalence of HTWC phenotype was significantly higher in adolescents with family history than that in those without family history (4 .4% vs 2 .5% ,χ2 =8 .468 ,P =0 .004) .After adjusting for gender and age ,the prevalence of HTWC phenotype among adolescents with family history was 1 .735 (95% CI:1 .167~2 .578 ,P =0 .006) folds of those without family history .[Conclusion]A significant correlation exists between a family history of obesity and HTWC phenotype .And it suggests that a family history of obesity is an independent risk factor for HT‐WC phenotype .
