Mental health care needs and preferences for mothers of children with a disability.

BACKGROUND: Mothers of children with a disability are at increased risk of poor mental health compared with mothers of typically developing children. The aim of the study was to describe the mental health care needs and preferences for support of mothers of children and young people aged 0-25 years with a disability. METHODS: A cross-sectional study was used, using an online survey with 294 mothers of children with a disability. Questions were asked about mental health, perceived need for support, barriers to accessing mental health care, and preferences for support. Descriptive and chi-squared analyses were performed. RESULTS: High rates of mental ill health were self-identified in the previous 12 months, with reported clinically significant depression (44%), anxiety (42%), and suicidality (22%). Nearly half (48%) of the mothers reported high to very high psychological distress. Although 75% of mothers perceived a need for professional support, only 58% attempted to access this. Key barriers to accessing support were caregiving duties making it difficult to schedule appointments (45%) and not perceiving the mental health problem as serious enough to require help (36%). Individual counselling was the preferred type of support (66%) followed by professionally guided relaxation (49%) and education about mental health (47%). Support was considered most critical at the time of diagnosis and during medical intervention for their child. CONCLUSIONS: Although mental health problems were common and mothers perceived the need for professional help, several key barriers were preventing mothers from accessing help. Our study suggests that improving mothers' knowledge of when and where to seek help (mental health literacy) may encourage their access to support. There also needs to be more accessible treatment to mothers given the high care demands that are placed upon them.

Identification of quantitative trait loci affecting reproduction in pigs.

The objective of this research was to identify chromosomal regions harboring QTL affecting reproduction in pigs. A three-generation resource population was developed by crossing low-indexing pigs from a randomly selected control line (C) with high-indexing pigs of a line selected for increased index of ovulation rate and embryonic survival (I). Differences between Lines I and C at Generation 10 were 6.7 ova and 3.3 fetuses at 50 d of gestation and 3.1 fully formed and 1.6 live pigs at birth. Phenotypic data were collected on F2 females, born in three replicates, for ovulation rate (n = 423), age at puberty (n = 295), litter size (n = 370), and number of nipples (n = 428). Litter-size data included number of fully formed, live, stillborn, and mummified pigs. Grandparent, F1, and F2 animals were genotyped for 151 microsatellite markers distributed across all 18 autosomes and the X chromosome. Genotypic data were available on 423 F2 females. Average spacing between markers was 19.3 Kosambi centimorgans. Calculations of logarithms of odds (LOD) scores were by least squares, and fixed effects for sire-dam combination and replicate were included in the models. Genome-wide significance level thresholds of 5% and 10% were calculated using a permutation approach. There was evidence (P < 0.05) for QTL affecting ovulation rate on SSC9, age at puberty on SSC7 and SSC8, number of nipples on SSC8 and SSC11, number of stillborn pigs on SSC5 and SSC13, and number of fully formed pigs on SSC11. There was evidence (P < 0.10) for additional QTL affecting age at puberty on SSC7, SSC8, and SSC12, number born live on SSC11, and number of nipples on SSC1, SSC6, and SSC7. Litter size is lowly heritable and sex-limited. Therefore, accuracy of selection for litter size may be enhanced by marker-assisted selection. Ovulation rate and age at puberty are laborious to measure, and thus marker-assisted selection may provide a practical and efficient method of selection.
