Adverse Outcomes to Early Middle Age Linked With Childhood Residential Mobility.

ABSTRACT:

Introduction

Links between childhood residential mobility and multiple adverse outcomes through to maturity, and effect modification of these associations by familial SES, are incompletely understood.

Methods

A national cohort of people born in Denmark in 1971-1997 were followed from their 15th birthdays until their early forties (N=1,475,030). Residential moves during each age year between birth and age 14 years were examined, with follow-up to 2013. Incidence rate ratios for attempted suicide, violent criminality, psychiatric illness, substance misuse, and natural and unnatural deaths were estimated. The analyses were conducted during 2014-2015.

Results

Elevated risks were observed for all examined outcomes, with excess risk seen among those exposed to multiple versus single relocations in a year. Risks grew incrementally with increasing age of exposure to mobility. For violent offending, attempted suicide, substance misuse, and unnatural death, sharp spikes in risk linked with multiple relocations in a year during early/mid-adolescence were found. With attempted suicide and violent offending, the primary outcomes, a distinct risk gradient was observed with increasing age at exposure across the socioeconomic spectrum.

Conclusions

The links between childhood residential mobility and negative outcomes in later life appear widespread across multiple endpoints, with elevation in risk being particularly marked if frequent residential change occurs during early/mid-adolescence. Heightened vigilance is indicated for relocated adolescents and their families, with a view to preventing longer-term adverse outcomes in this population among all socioeconomic groups. Risk management will require close cooperation among multiple public agencies, particularly child, adolescent, and adult mental health services.

Project description:Studies of environmental exposures and childhood cancers that rely on records often only use maternal address at birth or address at cancer diagnosis to assess exposures in early childhood, possibly leading to exposure misclassification and questionable validity due to residential mobility during early childhood. Our objective was to assess patterns and identify factors that may predict residential mobility in early childhood, and examine the impact of mobility on early childhood exposure assessment for agriculturally applied pesticides and childhood cancers in California. We obtained the addresses at diagnosis of all childhood cancer cases born in 1998-2011 and diagnosed at 0-5 years of age (n = 6478) from the California Cancer Registry (CCR), and their birth addresses from linked birth certificates. Controls were randomly selected from California birth records and frequency matched (20:1) to all cases by year of birth. We obtained residential histories from a public-record database LexisNexis for both case (n = 3877 with age at diagnosis 1-5 years) and control (n = 99,262) families. Logistic regression analyses were conducted to assess the socio-demographic factors in relation to residential mobility in early childhood. We employed a Geographic Information System (GIS)-based system to estimate children's first year of life exposures to agriculturally applied pesticides based on birth vs diagnosis address or residential histories based upon Lexis-Nexis Public Records and assessed agreement between exposure measures using Spearman correlations and kappa statistics. Over 20% of case and control children moved in their first year of life, and 55% of children with cancer moved between birth and diagnosis. Older age at diagnosis, younger maternal age, lower maternal education, not having a Hispanic ethnic background, use of public health insurance, and non-metropolitan residence at birth were predictors of higher residential mobility. There was moderate to strong correlation (Spearman correlation = 0.76-0.83) and good agreement (kappa = 0.75-0.81) between the first year of life exposure estimates for agricultural pesticides applied within 2 km of a residence relying on an address at birth or at diagnosis or LexisNexis addresses; this did not differ by outcome status, but agreement decreased with decreasing buffer size, and increasing distance moved or age at diagnosis. These findings suggest that residential addresses collected at one point in time may represent residential history in early childhood to a reasonable extent; nevertheless, they exposure misclassification in the first year of life remains an issue. Also, the highest proportion of women not captured by LexisNexis were Hispanic women born in Mexico and those living in the lowest SES neighborhoods, i.e. possibly those with the higher environmental exposures, as well as younger women and those with less than high school education. Though LexisNexis only captures a sub-population, its data may be useful for augmenting address information and assessing the extent of exposure misclassification when estimating environmental exposures in large record linkage studies. Future research should investigate how to correct for exposure misclassification introduced by residential mobility that is not being captured by records.

Project description:IMPORTANCE:Chorioamnionitis is strongly linked to preterm birth and neonatal infection. The association between histological and clinical chorioamnionitis and cognitive, behavioral, and neurodevelopmental outcomes among extremely preterm neonates is less clear. We evaluated the impact of chorioamnionitis on 18- to 22-month neurodevelopmental outcomes in a contemporary cohort of extremely preterm neonates. OBJECTIVE:To compare the neonatal and neurodevelopmental outcomes of 3 groups of extremely low-gestational-age infants with increasing exposure to perinatal inflammation: no chorioamnionitis, histological chorioamnionitis alone, or histological plus clinical chorioamnionitis. DESIGN, SETTING, AND PARTICIPANTS:Longitudinal observational study at 16 centers of the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network. Two thousand three hundred ninety extremely preterm infants born at less than 27 weeks' gestational age (GA) between January 1, 2006, and December 31, 2008, with placental histopathology and 18 to 22 months' corrected age follow-up data were eligible. MAIN EXPOSURE:Chorioamnionitis. MAIN OUTCOMES AND MEASURES:Outcomes included cerebral palsy, gross motor functional limitation, behavioral scores (according to the Brief Infant-Toddler Social and Emotional Assessment), cognitive and language scores (according to the Bayley Scales of Infant and Toddler Development, Third Edition), and composite measures of death/neurodevelopmental impairment. Multivariable logistic and linear regression models were developed to assess the association between chorioamnionitis and outcomes while controlling for important variables known at birth. RESULTS:Neonates exposed to chorioamnionitis had a lower GA and higher rates of early-onset sepsis and severe periventricular-intraventricular hemorrhage as compared with unexposed neonates. In multivariable models evaluating death and neurodevelopmental outcomes, inclusion of GA in the model diminished the association between chorioamnionitis and adverse outcomes. Still, histological plus clinical chorioamnionitis was associated with increased risk of cognitive impairment as compared with no chorioamnionitis (adjusted odds ratio [OR], 2.38 [95% CI, 1.32 to 4.28] without GA; adjusted OR, 2.00 [95% CI, 1.10 to 3.64] with GA as a covariate). Histological chorioamnionitis alone was associated with lower odds of death/neurodevelopmental impairment as compared with histological plus clinical chorioamnionitis (adjusted OR, 0.68 [95% CI, 0.52 to 0.89] without GA; adjusted OR, 0.66 [95% CI, 0.49 to 0.89] with GA as a covariate). Risk of behavioral problems did not differ statistically between groups. CONCLUSIONS AND RELEVANCE:Antenatal exposure to chorioamnionitis is associated with altered odds of cognitive impairment and death/neurodevelopmental impairment in extremely preterm infants.
