- Abstract: Objective To analyze the interaction between family history and waist circumference on incidence of hypertension .Methods We conducted a cross-sectional survey of rural residents in Hanzhong .Questionnaires about hypertension were collected and physical examination was conducted .A total of 3030 rural residents' data were collected . Logistic regression model was used to analyze the influences of family history and waist circumference on hypertension . Additive model and multiplicative model were used to analyze the interaction between family history and waist circumference on hypertension .Results For hypertension , Logistic regression analysis showed that family history (OR :2 .225 ,95% CI:1 .843-2 .687) and abdominal obesity (OR :1 .976 ,95%CI :1 .649-2 .368) were positively associated after adjustment for age ,sex ,salt intake ,smoking ,and alcohol drinking .Family history and waist circumference had no interaction on incidence of hypertension on a multiplicative scale but an interaction on an additive scale .The relative excess risk due to interaction (RERI) was 1 .848 (95% CI :0 .693-3 .002) ,the attributable proportion due to interaction (AP) was 0 .404 (95% CI :0 .227 -0 .582) and the synergy index (S) was 2 .073 (95% CI :1 .340 -3 .206 ) .Conclusion Family history and abdominal obesity are risk factors for hypertension . The incidence of hypertension of people with both family history and abdominal obesity is obviously higher than the sum of the two risk factors separately .Therefore ,to prevent hypertension it is more important for people to control their weight when they have a positive family history .
