Association between soy intake, infant feeding type, and obesity risk in adolescents Lynnley Huey, Edward Bitok, Gina Segovia‐Siapco, Joan Sabaté; Department of Nutrition, School of Public Health, Loma Linda University, Loma Linda, California Soy consumption has been shown to be protective against chronic disease. The purpose of this investigation was to determine if regular soy consumption is associated with indicators of overweight/obesity‐ BMI z‐score (BMIZ), waist‐to‐height ratio (WHtR), and waist circumference (WC)‐ in adolescents. In a cross‐sectional study, 549 adolescents (310 females, 239 males) ages 12‐18 years old recruited from 10 schools filled out a web‐based food frequency questionnaire to report usual soy intake. Anthropometric measurements were taken during school visits. Associations between soy intake and BMIZ, WHtR and WC were analyzed using ANOVA, ANCOVA, and linear regression while controlling for relevant confounders. Average soy intake was 1.7 ± 1.9 servings per day (s/d), broken down as: meat analog (0.9 ± 1.1 s/d), soy beverages (0.5 ± 1.0 s/d), and tofu products (0.3 ± 0.6 s/d). Asians had a significantly greater intake of soy relative to Caucasians (p= 0.02). A greater proportion of adolescents who were mixed‐fed (28.4%) or formula‐fed (27.3%) as infants had higher BMIZ compared to those who were breastfed (21.8%). Total soy intake and each of the soy food types were not significantly associated with BMIZ, WHtR, or WC. In this population, regular soy consumption has a neutral effect on the risk of obesity.
