Abstract

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 .
