Omega-3 Index of Canadian adults
by Kellie Langlois and Walisundera M. N. Ratnayake

The purpose of this study is to estimate levels of two fatty acids—eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)—in terms of the Omega-3 Index and the cut-points for coronary heart disease (CHD) risk among a nationally representative sample of Canadian adults. Factors related to Omega-3 Index levels and potential associ­ations with CHD-related factors are examined, using direct measures of RBC fatty acids from the 2012/2013 Canadian Health Measures Survey.

A surveillance tool to assess diets according to Eating Well with Canada’s Food Guide
by Lisa-Anne Elvidge Munene, Lydia Dumais, Krista Esslinger, Elaine Jones-Mclean, Elizabeth Mansfield, Marie-France Verreault, Maya Villeneuve, Doris Miller and Sylvie St-Pierre

A surveillance tool was developed to assess dietary intake collected by surveys in relation to Eating Well with Canada’s Food Guide (CFG). The tool classifies foods in the Canadian Nutrient File (CNF) according to how closely they reflect CFG. This paper describes the validation exercise conducted to ensure that CNF foods determined to be “in line with CFG” were appropriately classified.

Housing and health among Inuit children
by Dafna E. Kohen, Evelyne Bougie and Anne Guèvremont

Housing conditions have been associated with child health. Inuit children are generally in poorer health than other Canadian children. They are also more likely to live in crowded households, in dwellings that need major repair, and to be exposed to second-hand smoke in the home. This study uses the 2006 Aboriginal Children’s Survey to examine associations between physical and psychosocial housing characteristics and physical and mental health outcomes of Inuit children aged 2 to 5.

Modelling mammography screening for breast cancer in the Canadian context: Modification and testing of a microsimulation model
by Martin J. Yaffe, Nicole Mittmann, Pablo Lee, Anna N.A. Tosteson, Amy Trentham-Dietz, Oguzhan Alagoz and Natasha K. Stout

This article describes the modification and testing of a validated microsimulation model of breast cancer, which was developed based on the U.S. population. The modifications reflect the current Canadian context—Canadian-specific data on detection and treatment were incorporated into the model or used as inputs.

Clinical outcomes of modelling mammography screening strategies
by Martin J. Yaffe, Nicole Mittmann, Pablo Lee, Anna N.A. Tosteson, Amy Trentham-Dietz, Oguzhan Alagoz and Natasha K. Stout

This analysis employs a validated microsimulation model of breast cancer, adapted to the Canadian context, to predict health outcomes associated with different digital mammography screening strategies (including No Screening) across different age ranges. The model estimates the benefits, harms, limitations, and use of resources for each strategy.

Total cost-effectiveness of mammography screening strategies
by Nicole Mittmann, Natasha K. Stout, Pablo Lee, Anna N.A. Tosteson, Amy Trentham-Dietz, Oguzhan Alagoz and Martin J. Yaffe

The objective of this analysis was to evaluate the costs, outcomes and cost effectiveness of various mammography strategies, using a validated breast cancer simulation model.
