Parenting and family environment have significant impact on child development, including development of executive function, attention, and self-regulation, and may affect the risk of developmental disorders including attention-deficit/hyperactivity disorder (ADHD). This paper examines the relationship of parenting and family environment factors with ADHD. A systematic review of the literature was conducted in 2014 and identified 52 longitudinal studies. A follow-up search in 2021 identified 7 additional articles, for a total of 59 studies that examined the association of parenting factors with ADHD outcomes: ADHD overall (diagnosis or symptoms), ADHD diagnosis specifically, or presence of the specific ADHD symptoms of inattention and hyperactivity/impulsivity. For parenting factors that were present in three or more studies, pooled effect sizes were calculated separately for dichotomous or continuous ADHD outcomes, accounting for each study's conditional variance. Factors with sufficient information for analysis were parenting interaction quality (sensitivity/warmth, intrusiveness/reactivity, and negativity/harsh discipline), maltreatment (general maltreatment and physical abuse), parental relationship status (divorce, single parenting), parental incarceration, and child media exposure. All factors showed a significant direct association with ADHD outcomes, except sensitivity/warmth which had an inverse association. Parenting factors predicted diagnosis and overall symptoms as well as inattentive and hyperactive symptoms when measured, but multiple factors showed significant heterogeneity across studies. These findings support the possibility that parenting and family environment influences ADHD symptoms and may affect a child's likelihood of being diagnosed with ADHD. Prevention strategies that support parents, such as decreasing parenting challenges and increasing access to parent training in behavior management, may improve children's long-term developmental health.

Research suggests that breastfeeding may reduce child maltreatment risk. Alaska has high rates of both breastfeeding initiation and maltreatment reports to Child Protective Services (CPS). The present study assessed any and exclusive breastfeeding duration and child maltreatment reports to CPS among Alaskan mother-infant dyads, controlling for demographics and shared risk factors. We used a prospective, population-representative dataset linking 2009–2011 Alaska Pregnancy Risk Assessment Monitoring System (PRAMS) data with 2009–2016 Alaska CPS and administrative state data (n = 3,459). Breastfeeding duration was derived from PRAMS breastfeeding questions and categorized as never, < 1 weeks, 1—9 weeks, and ≥ 10 weeks. Age at first report of maltreatment to Alaska CPS included physical or sexual abuse, neglect, or mental injury. Hazard ratios and 95% confidence intervals (CI) were calculated using Cox proportional hazard models, adjusting for confounders. There was no increase in risk of maltreatment report among children never breastfed compared to those breastfed for ≥ 10 weeks. Risk of maltreatment report during the observation period was 1.7 times as high among children breastfed for < 1 week (CI: 1.06, 2.73), and 1.5 times as high among those breastfed for 1–9 weeks (CI: 1.17, 1.80), compared to those breastfed for ≥ 10 weeks. Estimates were attenuated for exclusive breastfeeding. Feeding method did not predict maltreatment reports in this population. Among mothers who initiated breastfeeding, shorter duration was associated with elevated risk of maltreatment reports. Addressing factors that facilitate or prohibit sustained breastfeeding may reduce risk of child maltreatment reports. [ABSTRACT FROM AUTHOR]
