Resumo O objetivo do estudo foi investigar as características socioeconômicas e obstétricas de parturientes adolescentes e suas complicações sobre a saúde materna e neonatal. Trata-se de uma análise de dados da linha de base da coorte de nascimentos MINA-Brasil conduzida no município de Cruzeiro do Sul, estado do Acre. Utilizou-se teste qui-quadrado para comparar características das puérperas adolescentes com as adultas e modelos múltiplos de regressão de Poisson com variância robusta para avaliar fatores associados. Entre as puérperas estudadas, 26,2% (IC95%: 24,0-28,4) eram adolescentes. Os fatores associados ao parto na adolescência foram ter nove anos ou menos de estudo (RPaj:1,36; IC95%: 1,14-1,61), pertencer aos menores quartis do índice de riqueza (1° quartil: RPaj:1,40; IC95%: 1,08-1,80) (2° quartil: RPaj:1,37; IC95%: 1,08-1,74), ser primigesta (RPaj:3,69; IC95%: 2,98-4,57), baixo IMC pré-gestacional (RPaj:1,28; IC95%: 1,04-1,57), infecção urinária na gravidez (RPaj:1,25; IC95%: 1,07-1,46) e menos de seis consultas de pré-natal (RPaj:1,42; IC95%: 1,21-1,66). Pobreza, baixa escolaridade, primigestação, baixo IMC pré-gestacional, infecção urinária na gestação e menor número de consultas de pré-natal foram associados ao parto na adolescência em município da região Norte do Brasil. neonatal Tratase Trata se MINABrasil MINA Brasil Sul Acre Utilizouse Utilizou quiquadrado qui quadrado estudadas 262 26 2 26,2 IC95% IC95 IC (IC95% 24,028,4 240284 24,0 28,4 24 0 28 4 24,0-28,4 RPaj1,36 RPaj136 RPaj 1,36 1 36 (RPaj:1,36 1,141,61, 114161 1,14 1,61 , 14 61 1,14-1,61) 1° (1 quartil RPaj1,40 RPaj140 1,40 40 RPaj:1,40 1,081,80 108180 1,08 1,80 08 80 1,08-1,80 2° (2 RPaj1,37 RPaj137 1,37 37 RPaj:1,37 1,081,74, 108174 1,74 74 1,08-1,74) RPaj3,69 RPaj369 3,69 3 69 (RPaj:3,69 2,984,57, 298457 2,98 4,57 98 57 2,98-4,57) prégestacional pré gestacional RPaj1,28 RPaj128 1,28 (RPaj:1,28 1,041,57, 104157 1,04 1,57 04 1,04-1,57) RPaj1,25 RPaj125 1,25 25 (RPaj:1,25 1,071,46 107146 1,07 1,46 07 46 1,07-1,46 prénatal natal RPaj1,42 RPaj142 1,42 42 (RPaj:1,42 1,211,66. 121166 1,21 1,66 . 21 66 1,21-1,66) Pobreza escolaridade primigestação prégestacional, gestacional, 26, IC9 (IC95 028 24,028, 24028 240 24, 284 28, 24,0-28, RPaj1 RPaj1,3 RPaj13 136 1,3 (RPaj:1,3 141 1,141,61 11416 114 1,1 161 1,6 6 1,14-1,61 ( RPaj1,4 RPaj14 140 1,4 RPaj:1,4 081 1,081,8 10818 108 1,0 180 1,8 8 1,08-1,8 137 RPaj:1,3 1,081,74 10817 174 1,7 7 1,08-1,74 RPaj3 RPaj3,6 RPaj36 369 3,6 (RPaj:3,6 984 2,984,57 29845 298 2,9 457 4,5 9 5 2,98-4,57 RPaj1,2 RPaj12 128 1,2 (RPaj:1,2 041 1,041,57 10415 104 157 1,5 1,04-1,57 125 071 1,071,4 10714 107 146 1,07-1,4 142 (RPaj:1,4 211 1,211,66 12116 121 166 1,21-1,66 (IC9 02 24,028 2402 24,0-28 RPaj1, 13 1, (RPaj:1, 1,141,6 1141 11 16 1,14-1,6 RPaj:1, 1,081, 1081 10 18 1,08-1, 1,081,7 17 1,08-1,7 RPaj3, 3, (RPaj:3, 2,984,5 2984 29 2, 45 4, 2,98-4,5 12 1,041,5 1041 15 1,04-1,5 1,071, 1071 1,07-1, 1,211,6 1211 1,21-1,6 (IC 24,02 24,0-2 (RPaj:1 1,141, 1,14-1, RPaj:1 1,081 1,08-1 (RPaj:3 2,984, 2,98-4, 1,041, 1,04-1, 1,071 1,07-1 1,211, 1,21-1, 24,0- (RPaj: 1,141 1,14-1 RPaj: 1,08- 2,984 2,98-4 1,041 1,04-1 1,07- 1,211 1,21-1 (RPaj 1,14- 2,98- 1,04- 1,21-
Abstract The present study aimed to investigate the socioeconomic and obstetric characteristics of adolescent mothers and the complications they cause to maternal and neonatal health. This baseline data analysis of the MINA-Brazil birth cohort was conducted in the municipality of Cruzeiro do Sul, state of Acre, Brazil. The chi-square test was used to compare characteristics of adolescent and adult postpartum women, and multiple Poisson regression models with robust variance were used to assess associated factors. Among the postpartum women, 26.2% (95%CI: 24.0-28.4) were adolescents. Factors associated with childbirth in adolescence included: nine years or less of schooling (adjPR:1.36; 95%CI: 1.14-1.61), belongs to the lowest quartiles of the wealth index (1st quartile: adjPR:1.40; 95%CI: 1.08-1.80) (2nd quartile: adjPR:1.37; 95%CI: 1.08-1.74), primigravidae (adjPR:3.69; 95%CI: 2.98-4.57), low pre-pregnancy BMI (adjPR:1.28; CI95%: 1.04-1.57), urinary tract infection during pregnancy (adjPR:1.25; CI95%: 1.07-1.46) and less than six prenatal consultations (adjPR:1.42; 95%CI: 1.21-1.66). Poverty, little schooling, primigravidae, low pre-pregnancy BMI, urinary tract infection during pregnancy and few prenatal consultations were associated with childbirth during adolescence in a municipality in the Northern region of Brazil. health MINABrazil MINA Brazil Sul Acre chisquare chi square women factors 262 26 2 26.2 95%CI 95CI CI 95 (95%CI 24.028.4 240284 24.0 28.4 24 0 28 4 24.0-28.4 adolescents included adjPR1.36 adjPR136 adjPR 1.36 1 36 (adjPR:1.36 1.141.61, 114161 1.14 1.61 , 14 61 1.14-1.61) 1st st quartile adjPR1.40 adjPR140 1.40 40 adjPR:1.40 1.081.80 108180 1.08 1.80 08 80 1.08-1.80 2nd nd adjPR1.37 adjPR137 1.37 37 adjPR:1.37 1.081.74, 108174 1.74 74 1.08-1.74) adjPR3.69 adjPR369 3.69 3 69 (adjPR:3.69 2.984.57, 298457 2.98 4.57 98 57 2.98-4.57) prepregnancy pre adjPR1.28 adjPR128 1.28 (adjPR:1.28 CI95% CI95 1.041.57, 104157 1.04 1.57 04 1.04-1.57) adjPR1.25 adjPR125 1.25 25 (adjPR:1.25 1.071.46 107146 1.07 1.46 07 46 1.07-1.46 adjPR1.42 adjPR142 1.42 42 (adjPR:1.42 1.211.66. 121166 1.21 1.66 . 21 66 1.21-1.66) Poverty 26. 9 028 24.028. 24028 240 24. 284 28. 24.0-28. adjPR1 adjPR1.3 adjPR13 136 1.3 (adjPR:1.3 141 1.141.61 11416 114 1.1 161 1.6 6 1.14-1.61 adjPR1.4 adjPR14 140 1.4 adjPR:1.4 081 1.081.8 10818 108 1.0 180 1.8 8 1.08-1.8 137 adjPR:1.3 1.081.74 10817 174 1.7 7 1.08-1.74 adjPR3 adjPR3.6 adjPR36 369 3.6 (adjPR:3.6 984 2.984.57 29845 298 2.9 457 4.5 5 2.98-4.57 adjPR1.2 adjPR12 128 1.2 (adjPR:1.2 CI9 041 1.041.57 10415 104 157 1.5 1.04-1.57 125 071 1.071.4 10714 107 146 1.07-1.4 142 (adjPR:1.4 211 1.211.66 12116 121 166 1.21-1.66 02 24.028 2402 24.0-28 adjPR1. 13 1.
