Unhealthy habits in teens from lower socioeconomic households raises risk of heart disease

The study, which will be presented Sunday at the Canadian Cardiovascular Congress in Vancouver, is the result of a collaboration with Heart Niagara Inc.’s Healthy Heart Schools’ Program, which provides cardiovascular screening to all Grade 9 students in the Niagara region. The screening involves recording each student’s height, weight, body mass index (BMI), waist circumference, blood pressure and cholesterol levels.

“People with higher socioeconomic status tend to have more resources, knowledge and time to devote to a healthy lifestyle. Those with lower socioeconomic status are often focused on more immediate concerns, like stretching their paycheque to cover food and rent,” says Dr. Brian McCrindle, principal investigator of the study, Staff Cardiologist and Senior Scientist at SickKids. “By taking socioeconomic status into consideration, health-care providers can target youth and families at risk of heart disease and design adaptive interventions to address the behavioural factors in this population.”

The research involved Heart Niagara’s collection of cross-sectional data for cardiovascular risk factors and health behaviours in more than 4,000 students aged 14 to 15 during the 2009-2010 school year.

Researchers examined the data collected from the universal screening program and matched participants’ postal codes with socioeconomic status measures from the 2006 Census Canada data. These include household income, home ownership and highest educational degree in the home. They then looked at health behaviours such as physical activity, screen time, smoking, snacking habits and fruit/vegetable consumption. They also examined factors that may contribute to cardiovascular risk, like BMI, cholesterol and blood pressure.

The researchers found higher BMI and cholesterol were linked with lower income and education. Elevated blood pressure was significantly associated with lower income. Sedentary lifestyle, poor nutrition and smoking were strongly related to lower socioeconomic status.

“The Healthy Heart Schools’ Program works across socioeconomic barriers to identify premature future risk and is reaching adolescents who may not be getting wellness checks,” says Karen Stearne of Heart Niagara Inc., a not-for-profit charitable organization that supports educators and helps both children and adults take responsibility for their heart health by providing assessment, referrals, training and tools.

“As health-care providers, we need to teach youth that you don’t need a gym membership to be active. There are low-cost strategies to maintain a healthy lifestyle,” says McCrindle, who is also Professor in the Department of Paediatrics at the University of Toronto and CIBC World Markets Children’s Miracle Foundation Chair in Child Health Research at SickKids and the University of Toronto.

McCrindle and colleagues offer tips and tools for creating healthy weight programs for children and teens at www.healthy.obesityinyouth.org.

Dr. Sarah Lord, lead author of the study and a resident at the University of Toronto, will present the study on Sunday.

The study was funded by Heart Niagara Inc., the Canadian Institutes of Health Research and SickKids Foundation.
