Among primiparous women ( IFA = 131 ; MMN = 110 ; LNS = 128 ) , the LNS group had greater mean birth length ( +0.91 cm ; P = 0.001 ) , LAZ ( +0.47 ; P = 0.001 ) , weight ( +237 g ; P < 0.001 ) , WAZ ( +0.56 ; P < 0.001 ) , BMIZ ( +0.52 ; P < 0.001 ) , head circumference ( 0.50 cm ; P = 0.017 ) , and head circumference-for-age z score ( +0.40 ; P = 0.022 ) than did the IFA group ; similar differences were found when comparing the LNS and MMN groups among primiparous women , and no group differences were found among multiparous women .
