The importance of family support to engage and retain girls in male dominated action sports. A qualitative study of young people's perspectives

ISSUE ADDRESSED

Social support is positively correlated with physical activity (PA), especially amongst girls, but is underexplored in male-dominated action sports (e.g., mountain biking, skateboarding and surfing). This study explored family level social support needs and experiences of girls and boys in three action sports.

METHOD

Aspiring, current or former Australian adolescent (12-18 years; girls n = 25; boys n = 17) mountain bikers, skateboarders and/or surfers were individually interviewed (telephone/Skype) in 2018/2020. A socio-ecological framework guided the semi-structured interview schedule. Audio-recordings were transcribed verbatim and data analysed thematically using a constant comparative approach.

RESULTS

Family level social support was highly influential in young people's participation in action sports, with its absence a common reason for no or discontinued engagement amongst girls. Parents and siblings were the main social support providers with extended family (e.g., grandparents, aunts/uncles, cousins) also notable. Participation (current/past/co-) was the main social support type followed by emotional (e.g., encouragement), instrumental (e.g., transport, equipment/funding) and informational (e.g., coaching) support. Girls were inspired/encouraged by brothers but boys were not inspired/encouraged by sisters; boys and girls co-participated with both parents but co-participating and being inspired by fathers was most common, especially amongst girls; fathers were more commonly the main transport provider if they co-participated with their child; fathers mostly provided initial coaching; only boys were taught equipment maintenance by parents.

CONCLUSIONS AND SO WHAT

Sport-related organisations/groups have numerous opportunities to improve girls' representation in action sports by fostering family level social support through various means. Intervention strategies should be tailored to account for gendered participation differences.

Cell-layer specific roles for gibberellins in nodulation and root development

Gibberellins (GA) have a profound influence on the formation of lateral root organs. However, the precise role this hormone plays in the cell-specific events during lateral root formation, rhizobial infection and nodule organogenesis, including interactions with auxin and cytokinin (CK), is not clear. We performed epidermal- and endodermal-specific complementation of the severely GA-deficient na pea (Pisum sativum) mutant with Agrobacterium rhizogenes. Gibberellin mutants were used to examine the spatial expression pattern of CK (TCSn)- and auxin (DR5)-responsive promoters and hormone levels. We found that GA produced in the endodermis promote lateral root and nodule organogenesis and can induce a mobile signal(s) that suppresses rhizobial infection. By contrast, epidermal-derived GA suppress infection but have little influence on root or nodule development. GA suppress the CK-responsive TCSn promoter in the cortex and are required for normal auxin activation during nodule primordia formation. Our findings indicate that GA regulate the checkpoints between infection thread (IT) penetration of the cortex and invasion of nodule primordial cells and promote the subsequent progression of nodule development. It appears that GA limit the progression and branching of IT in the cortex by restricting CK response and activate auxin response to promote nodule primordia development.

Economic evaluation of an Australian nurse home visiting programme: a randomised trial at 3 years

OBJECTIVES

To investigate the additional programme cost and cost-effectiveness of 'right@home' Nurse Home Visiting (NHV) programme in relation to improving maternal and child outcomes at child age 3 years compared with usual care.

DESIGN

A cost-utility analysis from a government-as-payer perspective alongside a randomised trial of NHV over 3-year period. Costs and quality-adjusted life-years (QALYs) were discounted at 5%. Analysis used an intention-to-treat approach with multiple imputation.

SETTING

The right@home was implemented from 2013 in Victoria and Tasmania states of Australia, as a primary care service for pregnant women, delivered until child age 2 years.

PARTICIPANTS

722 pregnant Australian women experiencing adversity received NHV (n=363) or usual care (clinic visits) (n=359).

PRIMARY AND SECONDARY OUTCOME MEASURES

First, a cost-consequences analysis to compare the additional costs of NHV over usual care, accounting for any reduced costs of service use, and impacts on all maternal and child outcomes assessed at 3 years. Second, cost-utility analysis from a government-as-payer perspective compared additional costs to maternal QALYs to express cost-effectiveness in terms of additional cost per additional QALY gained.

RESULTS

When compared with usual care at child age 3 years, the right@home intervention cost $A7685 extra per woman (95% CI $A7006 to $A8364) and generated 0.01 more QALYs (95% CI -0.01 to 0.02). The probability of right@home being cost-effective by child age 3 years is less than 20%, at a willingness-to-pay threshold of $A50 000 per QALY.

CONCLUSIONS

Benefits of NHV to parenting at 2 years and maternal health and well-being at 3 years translate into marginal maternal QALY gains. Like previous cost-effectiveness results for NHV programmes, right@home is not cost-effective at 3 years. Given the relatively high up-front costs of NHV, long-term follow-up is needed to assess the accrual of health and economic benefits over time.
