Background: Children living in food insecure households have poorer mental health outcomes compared with their food-secure peers; however, the relationship between the severity of food insecurity and diagnosed mental health conditions in young children remains unknown. This study examined the association between household food insecurity and reported diagnosed mental health conditions among children aged 5-11 years in Canada.
Methods: This study included 16 216 children aged 5-11 years living in Canada, from the 2019 Canadian Health Survey on Children and Youth.
Background: The public health measures associated with the COVID-19 pandemic may have indirectly impacted other health outcomes, such as falls among older adults. The purpose of this study was to examine trends in fall-related hospitalizations and emergency department visits among older adults before and during the COVID-19 pandemic in Ontario, Canada.
Methods: We obtained fall-related hospitalizations (N = 301,945) and emergency department visit (N = 1,150,829) data from the Canadian Institute for Health Information databases from 2015 to 2022 for adults ages 65 and older in Ontario.
Article Synopsis
- A study tested the effectiveness of health warning labels (HWL) about the alcohol-cancer link on consumer perceptions and intentions regarding ready-to-drink alcoholic beverages, comparing these effects with nutrient content claims (NCC) and nutritional declarations (ND).
- Over 5,000 Canadian alcohol consumers participated, and findings showed that all label conditions with HWL led to lower perceived healthiness, decreased product appeal, and reduced intentions to buy or consume the product.
- The HWL alone influenced participants to intend to buy fewer cans in the following week, with the study also noting minimal differences in label effects based on gender and age.
Introduction: Alcohol-attributable harms are increasing in Canada. We described trends in alcohol-attributable hospitalisations and emergency department (ED) visits by age, sex, drinking group, attribution and health condition.
Methods: Hospitalisation and ED visits for partially or wholly alcohol-attributable health conditions by age and sex were obtained from population-based health administrative data for individuals aged 15+ in Ontario, Canada.
Purpose: Explore Canadians' dietary intake in relation to the 2019 (CFG) Plate using novel volume-based food analyses, by age and meal occasion.
Methods: Foods reported in 24-hour recalls by 20,456 Canadians in the 2015 Canadian Community Health Survey - Nutrition were classified as: Vegetables and Fruits, Whole Grain Foods, Protein Foods, Non-Whole Grain Foods or Other Foods (high in fat, sugar, sodium). Food volumes were used to calculate percent contributions of each grouping to total intake, stratified by age (1-6; 7-12; 13-17; 18-64; 65+years) and meal (breakfast, lunch, supper, snack), applying sample survey weights and bootstrapping.
Background: Studies of neighbourhood walkability and body mass index (BMI) have shown mixed results, possibly due to biases from self-reported outcomes or differential effects across age groups. Our objective was to examine relationships between walkability and objectively measured BMI in various age groups, in a nationally representative population.
Methods: The study population came from the 2007-2011 Canadian Health Measures Survey, a cross-sectional survey of a nationally representative Canadian population.
Objective: To evaluate whether combining three cycles of the Canadian Health Measures Survey (CHMS) produces provincially representative and valid estimates of overweight and obesity in Ontario and Quebec.
Setting: An ongoing, nationally representative health survey in Canada, with data released every 2 years. Objective measures of height and weight were taken at mobile examination centres located within 100 km of participants' residences.
Background: Research has shown that neighbourhood walkability is associated with small differences in physical activity; however, the health impacts of these small differences have been questioned. We examined the size of the association of walkability with accelerometer-measured physical activity in a large, national-level Canadian population, and compared results to physical activity levels recommended in international guidelines. Our primary objective was to investigate the direction and size of the differences in physical activity that were related to walkability, and whether these differences depended on age.

Methods: Walkability was measured by Walk Score® (2012-2014) and physical activity by the Canadian Community Health Survey (2007-2012) for urban participants who worked or attended school. Multiple linear regression was done on the total study population, four age subgroups (12-17, 18-29, 30-64, 65+) and three population center subgroups (1000-29,999, 30,000-99,999, 100,000+).
Objective: To assess whether the completeness of reporting of health research is related to journals' endorsement of reporting guidelines.
Design: Systematic review.
Data Sources: Reporting guidelines from a published systematic review and the EQUATOR Network (October 2011).
Background: Hypertension has been cited as the most common attributable risk factor for death worldwide, and in Canada more than one of every five adults had this diagnosis in 2007. In addition to different lifestyle modifications, such as diet and exercise, there exist many pharmaco-therapies from different drug classes which can be used to lower blood pressure, thereby reducing the risk of serious clinical outcomes. In moderate and severe cases, more than one agent may be used.
