Insights into parents' perceived worry before and during the COVID-19 pandemic in Australia: inequality and heterogeneity of influences.

Background: Excessive worry is an invisible disruptive force that has adverse health outcomes and may advance to other forms of disorder, such as anxiety or depression. Addressing worry and its influences is challenging yet crucial for informing public health policy.

Methods: We examined parents' worries, influences, and variability before and during COVID-19 pandemic and across geography.

Is there a correlation between children's outdoor active mobility behaviour and neighbourhood safety? A systematic review of the evidence.

Objective: To identify, summarise and evaluate evidence on the correlation between perceived and actual neighbourhood safety (personal and road danger) and diverse forms of outdoor active mobility behaviour (ie, active play, exercise, and travel) among primary-school-aged children.

Design: A systematic review of evidence from observational studies exploring children's active mobility behaviour and safety.

Data Sources: Six electronic databases were searched: Google Scholar, PubMed, Scopus, Science Direct, ProQuest and Web of Science from study inception until July 2020.

Children's outdoor active mobility behaviour and neighbourhood safety: a systematic review in measurement methods and future research directions.

Background: Numerous studies have examined the association between safety and primary school-aged children's forms of active mobility. However, variations in studies' measurement methods and the elements addressed have contributed to inconsistencies in research outcomes, which may be forming a barrier to advancing researchers' knowledge about this field. To assess where current research stands, we have synthesised the methodological measures in studies that examined the effects of neighbourhood safety exposure (perceived and measured) on children's outdoor active mobility behaviour and used this analysis to propose future research directions.
