Violent delinquency in a Brazilian birth cohort: the roles of breast feeding, early poverty and demographic factors

Abstract

Caicedo B, Gonçalves H, González DA, Victora CG. Violent delinquency in a Brazilian birth cohort: the roles of breast feeding, early poverty and demographic factors. Paediatric and Perinatal Epidemiology 2010; 24: 12–23.We investigated the association between breast feeding, economic factors and conviction for violent delinquency by age 25 years among subjects of the 1982 Birth Cohort from Pelotas, Southern Brazil. Information on breast-feeding pattern and duration was collected in childhood, during the 1983, 1984 and 1986 follow-ups. Information on socio-economic and family characteristics was also obtained between 1982 and 1996. Of the 5914 livebirths enrolled in the cohort, 5228 had obtained an identification document within the state of Rio Grande do Sul, and could thus be identified in judiciary databases. The outcome studied was conviction due to a violent act between ages 12 and 25 years. A total of 106 young people had been convicted at least once (3.0% of men and 1.0% of women). Subjects born to black or mixed mothers and coming from low-income families were at higher risk of having been convicted. Neither crude nor adjusted analyses showed any association between breast feeding and conviction for violent delinquency. Violent delinquency apparently depends more on social factors than on individual factors such as breast feeding.

Association of Breastfeeding and Adolescents' Psychopathology: A Large Prospective Study

“…[8][9][10][11][12][13] Our finding that a shorter duration of breastfeeding is associated with the child's attention problems is consistent with the results of Julvez et al 12 Our data also confirm the findings of previous studies that suggested the relationship between breastfeeding and child conduct problems or delinquency is due to the effect of confounding. 8,14 In addition, the present study is in agreement with the research of Fergusson and Woodward 9 that found no significant association between breastfeeding and offspring's anxiety and depression between 16 and 18 years. However, it contradicts a recent cohort study by Oddy et al 13 that found association between breastfeeding and adolescent internalizing problems at 14 years.…”

Breastfeeding and behavior disorders among children and adolescents: a systematic review

“…The majority of the studies had a longitudinal design and started during pregnancy or right after birth: one was an intervention study 35 , one was retrospective 32 , and the others were prospective. Fourteen studies assessed only children 19 , 27 , 29 , 30 , 32 – 41 , three included only adolescents 28 , 31 , 42 , and one assessed both 26 .…”

“…Fifteen studies assessed the association between breastfeeding and children's behavior 19 , 26 , 27 , 29 , 30 , 32 – 41 , and ten of them found some association between breastfeeding and child behavior 26 , 27 , 29 , 30 , 32 , 34 , 36 , 38 – 40 . Regarding breastfeeding assessment, seven studies assessed EBF 19 , 29 , 33 , 34 , 36 , 38 , 41 and twelve 26 , 27 , 30 , 32 – 35 , 37 – 41 studies assessed NEBF.…”

“…Some studies have reported benefits of breastfeeding on emotional and behavioral development in children and adolescents 12 – 16 , whilst others with the same aim have not found any association 17 – 19 .…”
