Between duration of breastfeeding and adult

Longer duration of breastfeeding is linked with increased intelligence in adulthood, longer schooling, and higher adult earnings, a study following a group of almost 3, newborns for 30 years. Journal Reference: The distribution of duration of breastfeeding was almost identical for this sample and for the males for whom information on duration of breastfeeding was available, but who because of lack of a BPP score, overlap with the WAIS sample, or twin status were excluded. Consequently, unless otherwise specified, duration of breastfeeding refers to total duration of any breastfeeding. The distribution of duration of breastfeeding was nearly identical in these subjects and in the subjects included in the final sample. While the study showed increased adult intelligence, longer schooling, and higher adult earnings at all duration levels of breastfeeding, the longer a child was breastfed for up to 12 months , the greater the magnitude of the benefits. Content may be edited for style and length. The BPP sample had higher mean scores on gestational age, birth weight, and birth length and lower mean scores on parental social status and the indexes of pregnancy and delivery complications. In general, these differences were small: However, the only previous study that investigated the relationship between breastfeeding and intelligence in adults had several methodological shortcomings. There has only been one investigation of the relationship between breastfeeding and intelligence in adults. Between duration of breastfeeding and adult



However, when family and perinatal factors were included in a regression model, the association lost significance. Exclusive breastfeeding beyond 6 months may be associated with nutrient deficiencies and suboptimal growth. However, the only previous study that investigated the relationship between breastfeeding and intelligence in adults had several methodological shortcomings. Information on breastfeeding was collected in early childhood. FULL STORY Longer duration of breastfeeding is linked with increased intelligence in adulthood, longer schooling, and higher adult earnings, a study following a group of almost newborns for 30 years published in The Lancet Global Health journal has found. Consequently, unless otherwise specified, duration of breastfeeding refers to total duration of any breastfeeding. What is unique about this study is the fact that, in the population we studied, breastfeeding was not more common among highly educated, high-income women, but was evenly distributed by social class. Thirteen potential confounders were included as covariates: The distribution of duration of breastfeeding was almost identical for this sample and for the males for whom information on duration of breastfeeding was available, but who because of lack of a BPP score, overlap with the WAIS sample, or twin status were excluded. It is possible that the mothers distinctly remembered when they completely stopped breastfeeding, but less clearly when they started to supplement breast milk. While the study showed increased adult intelligence, longer schooling, and higher adult earnings at all duration levels of breastfeeding, the longer a child was breastfed for up to 12 months , the greater the magnitude of the benefits. In an effort to overcome difficulties of interpreting previous studies, we describe the association between duration of breastfeeding and adult intelligence, applying 2 different intelligence measures, in 2 nonoverlapping samples from a perinatal cohort with a wide range of potentially confounding variables collected prospectively. Author information: The researchers divided these subjects into five groups based on the length of time they were breastfed as infants, controlling for 10 social and biological variables that might contribute to the IQ increase including family income at birth, parental schooling, genomic ancestry, maternal smoking during pregnancy, maternal age, birthweight, and delivery type. Thirteen potential confounders were included as covariates: For both samples, the number of subjects in each breastfeeding category is shown in Table 2. However, on several of the covariates in this study, the BPP sample differed significantly from the excluded males of the Perinatal Cohort who survived the first 4 weeks of life. Unadjusted and adjusted mean differences in intelligence test scores among the 5 breastfeeding categories were analyzed statistically for both samples, using the SPSS linear regression and analysis of variance routines SPSS Inc, Chicago, Ill, version Of the remaining contacted individuals, information on duration of breastfeeding was only available for potential subjects. Longer duration of breastfeeding is linked with increased intelligence in adulthood, longer schooling, and higher adult earnings, a study following a group of almost 3, newborns for 30 years. Based on preliminary regression analyses, the following variables were considered potential confounders and included as covariates in analyses of both the 3 WAIS IQs and the BPP scores: Content may be edited for style and length. Our finding that predominant breastfeeding is positively related to IQ in adulthood also suggests that the amount of milk consumed plays a role. A number of studies suggest a positive association between breastfeeding and cognitive development in early and middle childhood. The Lancet Global Health, ; 3 4: Journal Reference: Information on IQ and breastfeeding was available for just over half participants. Wechsler Adult Intelligence Scale Sample A subsample from the Perinatal Cohort participated in an ongoing research program between that focused on the developmental effects of prenatal and perinatal factors, in particular the effects of prenatal exposure to prescribed maternal medications. On the basis of this scale, the subjects in both samples were classified into 5 categories according to duration of breastfeeding: Twin pairs only comprised a small fraction of the 2 samples, and when analyses were conducted on samples that included twins, the results are essentially the same as those presented in Table 3.

One study observed significantly higher scores in breastfed children at 15 years of age on tests of nonverbal ability, mathematics, and reading ability, 4 and another study demonstrated a positive association between breastfeeding and high school attainment at 18 years of age. Author information: Unadjusted and adjusted mean differences in intelligence test scores among the 5 breastfeeding categories were analyzed statistically for both samples, using the SPSS linear regression and analysis of variance routines SPSS Inc, Chicago, Ill, version Twin pairs only comprised a small fraction of the 2 samples, and when analyses were conducted on samples that included twins, the results are essentially the same as those presented in Table 3. Comment in JAMA. This total score has a correlation of 0. For example, an infant who had been breastfed for at least a year gained a full four IQ points about a third of a standard deviation above the average , had 0. A number of studies have suggested a positive association between breastfeeding and cognitive and intellectual development in early and middle childhood. The association between duration of breastfeeding and adult intelligence. Consequently, we decided to include subjects who were exclusively breastfed for 7 months or longer in the analyses presented here. It was not possible to include a separate category for children who were never breastfed since they were coded as 1 to 2 weeks or less. For both samples, the number of subjects in each breastfeeding category is shown in Table 2. However, when family and perinatal factors were included in a regression model, the association lost significance. When the cohort was established, demographic, socioeconomic, prenatal, and postnatal medical data were recorded prospectively during pregnancy, at delivery, and at a 1-year examination. FULL STORY Longer duration of breastfeeding is linked with increased intelligence in adulthood, longer schooling, and higher adult earnings, a study following a group of almost newborns for 30 years published in The Lancet Global Health journal has found. Of the remaining contacted individuals, information on duration of breastfeeding was only available for potential subjects. Information on IQ and breastfeeding was available for just over half participants. In general, these differences were small: The BPP scores were available for of these, but singletons were excluded to avoid overlap with the WAIS sample; in addition, 76 twins were excluded. However, the only previous study that investigated the relationship between breastfeeding and intelligence in adults had several methodological shortcomings. In both samples, intelligence was assessed in young adulthood, an age when cognitive functioning is optimal and intelligence test scores are highly stable. There has only been one investigation of the relationship between breastfeeding and intelligence in adults. The BPP sample had higher mean scores on gestational age, birth weight, and birth length and lower mean scores on parental social status and the indexes of pregnancy and delivery complications. What is unique about this study is the fact that, in the population we studied, breastfeeding was not more common among highly educated, high-income women, but was evenly distributed by social class. The distribution of duration of breastfeeding was nearly identical in these subjects and in the subjects included in the final sample. Participants were given an IQ test Wechsler Adult Intelligence Scale, 3rd version at the average age of 30 years old and information on educational achievement and income was also collected. Content may be edited for style and length. A number of studies suggest a positive association between breastfeeding and cognitive development in early and middle childhood. In the WAIS and BPP samples, the 40 and 83 subjects who were exclusively breastfed for 7 months or longer obtained essentially the same adjusted mean test scores as the 87 and subjects who were partially breastfed for 7 months or longer. This means that the results may have been affected by individual differences in age-related decline in cognitive function or neurological diseases, 8 thus weakening the possible association between breastfeeding and adult intelligence.

The mean parental social status score of the final WAIS sample was slightly, but significantly, higher than the score of the remaining contacted subjects, but otherwise there were no significant differences with respect to the covariates included in the study Table 1. Consequently, we decided to include subjects who were exclusively breastfed for 7 months or longer in the analyses presented here. It was individually administered by 3 psychologists who were all completely blind to the subjects' breastfeeding status and other prenatal and perinatal information. However, the only previous study that investigated the relationship between breastfeeding and intelligence in adults had several methodological shortcomings.

Longer duration of breastfeeding is linked with increased intelligence in adulthood, longer schooling, and higher adult earnings, a study following a group of almost 3, newborns for 30 years. The association between duration of breastfeeding and adult intelligence. For example, an infant who had been breastfed for at least a year gained a full four IQ points about a third of a standard deviation above the average , had 0. The corresponding mean scores on the BPP were Of the remaining contacted individuals, information on duration of breastfeeding was only available for potential subjects. Author information: In both samples, intelligence was assessed in young adulthood, an age when cognitive functioning is optimal and intelligence test scores are highly stable. Previous studies from developed countries have been criticized for failing to disentangle the effect of breastfeeding from that of socioeconomic advantage, but our work addresses this issue for the first time. It was not possible therefore to make a detailed analysis of exclusive breastfeeding vs total duration of breastfeeding, but a preliminary analysis showed no significant intelligence differences between subsamples of infants who were exclusively breastfed vs partially breastfed. Few studies have examined the relationship between breastfeeding and intellectual development in older children and adolescents.

In general, these differences were small: When the cohort was established, demographic, socioeconomic, prenatal, and postnatal medical data were recorded prospectively during pregnancy, at delivery, and at a 1-year examination. In an effort to overcome difficulties of interpreting previous studies, we describe the association between duration of breastfeeding and adult intelligence, applying 2 different intelligence measures, in 2 nonoverlapping samples from a perinatal cohort with a wide range of potentially confounding variables collected prospectively. Based on preliminary regression analyses, the following variables were considered potential confounders and included as covariates in analyses of both the 3 WAIS IQs and the BPP scores: The samples were divided into 5 categories based on duration of breastfeeding, as assessed by physician interview with mothers at a 1-year examination. Journal Reference: Independent of a wide range of possible confounding factors, a significant positive association between duration of breastfeeding and intelligence was observed in 2 independent samples of young adults, assessed with 2 different intelligence tests. The final sample included singletons males and females , with a mean assessment age of However, on several of the covariates in this study, the BPP sample differed significantly from the excluded males of the Perinatal Cohort who survived the first 4 weeks of life.

Despite the fact that controlling for these factors generally resulted in diminution of the effect, the positive association of breastfeeding with various measures of cognitive function remained significant and thus appeared robust. A number of studies suggest a positive association between breastfeeding and cognitive development in early and middle childhood. With the exception of individuals with disqualifying diseases eg, epilepsy and diabetes and individuals who volunteer for military service at an earlier age, all Danish males are required to appear before the draft board at 18 years of age. Prospective longitudinal birth cohort study conducted in a sample of men and women and a sample of men, all of whom were born in Copenhagen, Denmark, between October and December It was not possible to include a separate category for children who were never breastfed since they were coded as 1 to 2 weeks or less. Twin pairs only comprised a small fraction of the 2 samples, and when analyses were conducted on samples that included twins, the results are essentially the same as those presented in Table 3.

However, these findings need to be corroborated by future studies designed to focus on long-term effects and important life outcomes associated with breastfeeding. Comment in JAMA. The level of significance was set at. According to Dr Horta, "The likely mechanism underlying the beneficial effects of breast milk on intelligence is the presence of long-chain saturated fatty acids DHAs found in breast milk, which are essential for brain development.
