Hypertension (HTN) and type 2 diabetes are common diseases; however, the effects of health behavior and body mass index (BMI) on their incidence and relationship are unclear. The purpose of this study was to investigate the associations among health behaviors, BMI, HTN, and type 2 diabetes.This study was a secondary data analysis using Korean Longitudinal Study of Aging data between 2010 and 2014 (third and fifth). The sample consisted of 3481 people aged 45 years or older. Path analysis was conducted using the generalized structural equation modeling of STATA 13.1 that enabled analyzing the types of binary variables and logit links.There were 129 underweight, 1714 normal, and 1638 overweight and obese individuals. In underweight and normal groups who had regular meals (B = 0.670, P < .001), BMI was higher. However, for those who were older (B = -0.041, P < .001) and female (B = -0.229, P = .021), BMI was lower. The incidence of HTN increased with age (B = 0.038, P = .001). In addition, the incidence of type 2 diabetes increased with age (B = 0.051, P = .005) and smoking (B = 1.539, P = .001). However, the incidence of type 2 diabetes was lower (B = -1.077, P = .036) for those who had regular meals. In the normal and overweight groups, BMI decreased with age (B = -0.033, P < .001). The incidence of HTN increased with age (B = 0.042, P < .001) and BMI (B = 0.145, P < .001). Moreover, the incidence of type 2 diabetes increased with age (B = 0.046, P < .001), smoking (B = 0.682, P = .020), and higher BMI (B = 0.151, P = .001).In the underweight and normal group, health behaviors were related to BMI. In the normal and overweight group, health behaviors were not related to BMI, but high BMI was related to the incidence of HTN and type 2 diabetes. Smoking has a direct effect on the incidence of type 2 diabetes. Thus, the importance of maintaining an ideal BMI and smoking cessation are highlighted.
