A "food insecurity poverty line" to replace the official threshold in Canadian rural and urban settings? A single-person household perspective.

Household food insecurity is associated with both low income and high cost of living, it is a potentially better measure for consumption compared to income. We use data on food insecurity and income from 10 years of the Canadian Community Health Survey (2007-2017) of single-person households (n = 145,044) to estimate the probability of being food insecure at the Canadian poverty thresholds (Market Basket Measure thresholds, or MBMs), and determine the income required to reach that probability in each MBM region, aggregated by province and rural/urban status. A regression model shows the probability of being food insecure at the MBM is approximately 30% which we call the Food Insecurity Poverty Line (FIPL). The income required to meet the FIPL is substantially different from the MBM, sometimes 1.25 times the MBM. This implies that food insecurity is a potential sentinel measure for poverty.

The effectiveness and decay of public health policy actions on infection-control behaviour in the general public: Evidence from a low-COVID prevalence jurisdiction.

BACKGROUND: Public health policies designed to influence individuals' infection-control behaviour are a tool for governments to help prevent the spread of disease. Findings on the impacts of policies are mixed and there is limited information on the effects of removing restrictions and how policies impact behavioural trends. METHODS: We use low-acuity emergency department visits from 12 hospitals in New Brunswick, Canada, (January 2017 -October 2021) as a proxy for infection-control behaviour and provide insight into the effects of the COVID-19 virus on a population with a low prevalence of cases. Quasi-experimental techniques (event studies) are applied to estimate the magnitude and persistence of effects of specific events (e.g., policy changes), to control for COVID-19 cases and vaccines, and to explore how the effectiveness of policy changes during the pandemic as more policies are introduced. RESULTS: Initial tightening of restrictions on March 11, 2020 reduced low-acuity emergency department visits by around 60% and reached a minimum after 30 days. Relaxing policies on social gatherings and personal services gradually increased low-acuity emergency department visits by approximately 50% after 44 days. No effects were found from policies lifting all restrictions, and reinstating a state of emergency on July 31, 2021, and September 24, 2021. CONCLUSION: These results suggest that policy interventions are less likely to be effective at influencing infection control behaviour with time and more policies introduced, and that tracking and publicly reporting case numbers can influence infection control behaviour.

Effect of Canada Child Benefit on Food Insecurity: A Propensity Score-Matched Analysis.

INTRODUCTION: Food insecurity-the inadequate access to food due to financial constraints-affects 1 in 6 households in Canada, with serious health implications. Family benefit programs supplementing income have shown potential in mitigating the risk of food insecurity, but there is little understanding of their protective effects. The authors aimed to estimate the impacts of the additional Canada Child Benefit provided to families with children aged <6 years on household food insecurity. METHODS: The authors sampled 28,435 households receiving Canada Child Benefit with children aged <8 years from the Canadian Income Survey 2018-2020 fielded in 2019-2021 and analyzed in 2022. Households without children aged <6 years were 1:1 propensity-score matched to those with children aged <6 years, who received up to $1,068 in additional Canada Child Benefit per child annually. The authors compared the 2 groups' 12-month food insecurity likelihood after matching. Subsample analyses were performed by household income, housing tenure, and household type. RESULTS: Receipt of the additional Canada Child Benefit ($724 on average) was associated with 2.89 (95% CI=1.35, 4.42) percentage points lower probability of experiencing food insecurity among recipients with children aged <6 years (from 24.30% to 21.42%). The association was similar across socioeconomic subgroups and significant among all but high-income earners and mortgage-free homeowners. CONCLUSIONS: The authors found plausibly causal evidence that the more generous Canada Child Benefit for Canadian families with young children reduces their probability of food insecurity. Increasing benefits for economically disadvantaged households, characterized by low incomes, single parenthood, and renting (versus owning), may improve the program's efficiency and equity in supporting families' food security.
