Urinary As concentrations in our infants were an order
of magnitude lower than the median 35 µg / L
of As in a Bangladeshi
population exposed to high drinking water As levels (median, 80 µg / L).28, 47 This was expected given the high rate
of breastfeeding in our populations29 and the lower
proportion of households with tap water As concentrations above the US Environmental Protection Agency standard
of 10 µg / L (12.5 % in our
study).
We found little evidence that between -
study heterogeneity in estimates was explained by age at measurement

of a minimum duration

proportion of the target
population in the main analysis (p = 0.2), whether breastfeeding was exclusive for at least 2 months (p = 0.2), method

population, has implications for both the health care system and the economy, conclude the authors
of the

~ Resistant starch and «the butyrate revolution» (review — abstract) «Early epidemiological

Here we see a very substantial two county
study (Alachua County, Florida and San Diego County, California) in which the authors, including Dr. Julie Levy, a noted TNR advocate, write, «In both counties, results

This
proportion is approximately double that
of children found to be at high risk in the general New South Wales
population (15 %) 27 but similar to the
proportion noted in other
studies of Aboriginal children (24 %, 5 22.5 % 28 and among Aboriginal participants in the New South Wales
Population Health Survey).27 There is only one other
study to date that has measured the factors associated with Aboriginal child and adolescent mental health.5 SEARCH makes an important, new contribution to this emerging area
of research by considering, for the first time, the impact
of carer psychological distress.

Parental mental illness Relatively little has been written about the effect
of serious and persistent parental mental illness on child abuse, although many
studies show that substantial
proportions of mentally ill mothers are living away from their children.14 Much
of the discussion about the effect
of maternal mental illness on child abuse focuses on the poverty and homeless - ness
of mothers who are mentally ill, as well as on the behavior problems
of their children — all issues that are correlated with involvement with child welfare services.15 Jennifer Culhane and her colleagues followed a five - year birth cohort among women who had ever been homeless and found an elevated rate
of involvement with child welfare services and a nearly seven - times - higher rate
of having children placed into foster care.16 More direct evidence on the relationship between maternal mental illness and child abuse in the general
population, however, is strikingly scarce, especially given the 23 percent rate
of self - reported major depression in the previous twelve months among mothers involved with child welfare services, as shown in NSCAW.17
Furthermore, a large
proportion of comparison participants qualified for a lifetime psychiatric diagnosis (combining subthreshold and full diagnoses)(Table 4), sometimes exceeding
population rates.40 It seems more compelling that differences at the mean age
of 41 years between probands and comparison participants reflect differential development, especially because findings are highly consistent with other, briefer follow - up
studies.
To ensure that the

Several
studies have addressed the validity
of the parent - reported SDQ in school - aged samples, predominantly confirming the intended 5 - factor structure.5, 6 A 3 - factor configuration
of externalizing (conduct problems and hyperactivity), internalizing (emotional and peer problems), and prosocial factors has also been proposed and suggested for use in epidemiologic
studies and in low - risk
populations.7, 8 The internal reliability
of SDQ subscales has been predominantly examined by using Cronbach's α, a measure
of the interrelatedness
of items; however, α estimates are a lower bound for reliability and is often underestimated.9 A meta - analytic review reported weighted mean α coefficients extracted from 26
studies that showed generally modest reliabilities for parent reports (0.53 < α < 0.76).10 McDonald's ω, which estimates the
proportion of a scale measuring a construct, typically yields higher reliability estimates but has rarely been used to assess reliability
of the SDQ.
We used complete case analysis because the
proportion of missing values in the

study sample was found to be representative
of the general
population of the United Kingdom at the start

proportion of married or cohabiting mothers, and a greater number
of owner - occupier families (Boyd et al. 2013).
