Disinhibited attachment behavior among infants reared at home: Relations to maternal severe mental illness and personality disorder symptoms.

Disinhibited attachment behavior (DAB) among infants is persistent and associated with behavioral and relational problems throughout childhood and adolescence. Little is known about risk factors for DAB among infants reared at home, although studies have linked DAB with maternal psychiatric hospitalization and maternal borderline personality disorder. The aim of the current study was to further assess the association between DAB, maternal severe mental illness (SMI; schizophrenia, bipolar disorder, and depression), and maternal PD symptoms. Ninety-three mothers and their infants participated in the study: 46.2% with SMI and 53.8% with no-diagnosis. During pregnancy, mothers were assessed on the Structured Clinical Interview for DSM-5 and the Standardized Assessment of Personality Abbreviated Scale a validated measure of personality disorder (PD) symptoms. Infants were assessed for DAB at 1 year of age using the rating of infant stranger engagement, assessed during the strange situation procedure. Infants of mothers with clinical levels of PD symptoms were significantly more likely to display DAB (OR = 3.44) compared to infants of mothers without clinical levels of PD symptoms. Maternal SMI was not significantly associated with infant DAB. Because most mothers with clinical levels of PD symptoms also had comorbid diagnoses in this study, further work is needed to evaluate the role of comorbidity. These results add to the emerging literature indicating that maternal personality symptoms may be a risk factor for indiscriminate forms of attachment behavior among home-reared infants.

Prenatal and early childhood predictors of intelligence quotient (IQ) in 7-year-old Danish children from the Odense Child Cohort.

BACKGROUND: Cognitive development measured as intelligence quotient can predict socioeconomic markers in adulthood. It is therefore of interest to determine predictors of childhood intelligence quotient. AIM: To assess intelligence quotient scores based on standardised Danish age-appropriate scores and to evaluate potential predictors of intelligence quotient. MATERIALS: At 7 years of age children in the Odense Child Cohort completed an abbreviated version of the Wechsler intelligence scale for children 5th edition consisting of four subtests (vocabulary, similarities, block design and matrix reasoning) from which the full scale intelligence quotient and verbal comprehension index were estimated. Potential predictors from pregnancy through childhood were collected from questionnaires, birth records and clinical examinations. METHODS: Intelligence quotient scores were investigated through descriptive statistics and linear regression models. RESULTS: The mean full scale intelligence quotient among 1375 children was 99.1 (95% confidence interval 98.5; 99.8) points. Higher full scale intelligence quotient scores were observed in girls 100.8 (95% confidence interval 100.0; 101.8) compared to boys 97.6 (96.7; 98.4), and in children of mothers with high and intermediate education 101.7 (100.4; 103.1) and 99.6 (98.7; 100.5), respectively, compared to low education 96.1 (94.9; 97.3). In linear regression analyses, longer maternal education and child sex (girls) remained strong predictors of intelligence quotient at age 7 years. In addition, paternal education, child head circumference and longer duration of breastfeeding were associated with higher intelligence quotient, whereas maternal overweight and obesity before pregnancy was associated with lower intelligence quotient. CONCLUSIONS: Mean intelligence quotient scores were comparable to the standardised mean intelligence quotient of 100 point of Danish peers. It is important to follow up these children to determine which predictors persist into adulthood.

Parental mental illness, attendance at preventive child healthcare and dental caries in the offspring: a nation-wide population-based cohort study.

PURPOSE: Severe mental illness (SMI) may interfere with parental caregiving practices and offspring development. Adhering to preventive well-child visits and maintaining good oral hygiene during early childhood requires parental involvement. Whether these activities are affected by parental SMI is unclear. The purpose of the present study was to determine whether children exposed to parental SMI are at increased risk of non-attendance to preventive well-child visits and vaccinations at age 0-5 years and of child dental caries experience at age 5 years. Furthermore, interactions between maternal psychiatric and sociodemographic variables in relation to an adverse child outcome were assessed. METHODS: Data were obtained from national Danish health registers. All children born in Denmark between January 1997 and December 2010 were followed from birth until their 6th birthday. RESULTS: 679,339 children were included in the study (51% male). Of these, 49,059 children (7.8%) had at least one parent with a lifetime SMI diagnosis. Children of parents with SMI had elevated odds of missing well-child visits and vaccinations (OR 1.41; 95% CI 1.39-1.44, p < 0.0001), and of child dental caries (OR 1.58; 95% CI 1.55-1.62, p < 0.0001). In the presence of maternal SMI, low socioeconomic classification and single-mother status added more to the elevated risk than specific maternal diagnosis or timing of last psychiatric contact. CONCLUSION: Parents with SMI are less compliant with preventive child healthcare activities than parents without SMI. This indicates a need for practical support to these families in order to prevent inequality in health among their offspring.
