Risk factors for stunting and underweight in 12 and 13-month old children in Iquitos, Peru, September 2011 to June 2012 (n = 796*).

*The analysis was restricted to the 880 children whose stool specimens were analyzed by the Kato-Katz method. The adjusted models include a sample size of 796 due to 84 missing responses on birth weight.**Reference group includes mild or no stunting (i.e. LAZ≥−2 SD) and mild or no underweight (i.e. WAZ≥−2 SD).***RR = risk ratio: Crude results include variables with a p level‡1RR for stunting adjusted for any STH infection, sex, age, birth weight, any hospitalizations since birth, development score and socioeconomic status;2RR for underweight adjusted for any STH infection, birth weight, continued breastfeeding, development score and socioeconomic status.‡NS = not statistically significant.†Up-to-date vaccinations include those scheduled between birth and 11 months of age (i.e. one dose of Bacille Calmette-Guérin (BCG), one dose of hepatitis B, three doses of polio, three doses of pentavalent, two doses of rotavirus, and two doses of pneumococcal vaccines).§Mean development score is the combined sum of the raw scores of each individual subtest of the Bayley-III.∥SES = socioeconomic status (lowest quartile = lowest SES; highest quartile = highest SES).Risk factors for stunting and underweight in 12 and 13-month old children in Iquitos, Peru, September 2011 to June 2012 (n = 796*).
