This study examined the association between a growth velocity measure ‐ excessive weight gain velocity (EWGV; >2SD WHO gender‐specific velocity standards) during two stages of infancy (1‐12 & 12‐18 months) and obesity risk at four years of age (BMI‐for‐age 蠅95 th percentile) in a low‐income population. Infants participating in MA WIC (2001‐2009) with post‐birth, 12‐month, 18‐month, and 4‐year growth measures and covariate data were included. Multivariate logistic regression controlled for child's gender, race/Hispanic ethnicity, exact age, birth weight, baseline height, height velocity, breastfeeding status, HH food insecurity, HH size, maternal education, age, BMI, and smoking status. Analyses were stratified by birth order (n=6,744 first‐born and 9,460 subsequent) and excluded those underweight at 4 years. The sample was diverse (66% non‐white); 4% experienced EWGV during 1‐12 months and 9% during 12‐18 months, and 23% were obese at 4‐years. First‐born children with EWGV during the first 12 months of life were 5 times as likely to be obese at 4 years [AOR=5.2, 95%CI=4.1‐6.8]and subsequently born children were 6 times as likely [AOR=6.0, 95%CI=4.7‐7.6]compared to children without EWGV. First and subsequent infants with EWGV during the 12‐18 month period were 3 times as likely to develop obesity compared to children without EWGV [firstborn AOR=3.2, 95%CI=2.7‐3.8; subsequent AOR=3.1, 95%CI=2.6‐3.6]. EWGV during the first 18 months of life is associated with an increased risk of preschool obesity, with EWGV during the first year of life conferring the greatest increase in risk. These results support the implementation of obesity prevention programs during the first year of life. Funding: ERS/USDA
