Objectives: As part of its 2020 Impact Goals, the American Heart Association (AHA) developed "Life's Simple 7" (LS7) metrics to assess and promote cardiovascular (CV) health in the American population. The LS7 metrics include seven subscales referred to as core health behaviors or health factors. Multiple studies have shown that the LS7 score is inversely associated with the risk of stroke, CV disease and mortality and all-cause mortality. To our knowledge, the LS7 score has never been evaluated in a Canadian cohort. Therefore, the purpose of this study was to assess the overall CV health of French Canadians using the LS7 score.
Methods: A total of 771 participants (366 men and 405 women, mean age 42.5 ± 13.2 (SD)) from the PREDISE study were considered for these analyses. Their dietary intake was assessed using a validated web-based 24-hour recall completed on 3 occasions. Physical activity (PA) was assessed using the International Physical Activity Questionnaire. Each metric of the LS7 score (health behaviors: smoking, PA, diet, body mass index (BMI); health factors: fasting total cholesterol and blood glucose, blood pressure (BP)) was first categorized as "ideal", "intermediate" or "poor" for each subject according to AHA's criteria. The final score ranged from 0 to 7 based on the number of metrics that met the "ideal" criteria.
Results: Only 0.1% of participants met AHA's criteria for ideal CV health. The diet score, which is based on intake of fiber-rich whole grain products, sodium, fruits and vegetables, sugar-sweetened beverages and fish, showed the lowest prevalence of "ideal" scores (4.8%) whereas "ideal" blood glucose (<100mg/dL) was the metric with the highest prevalence (79.6%). The LS7 score was higher among women than men (3.9±1.4 vs. 3.4±1.5, p=0.0004), with more women achieving the "ideal" status for total cholesterol (<200mg/dL), BP (<120/80 mmHg), blood glucose and BMI (<25kg/m2) than men (all p<0.05).
Conclusions: Consistent with other studies conducted among different populations, very few French Canadians achieve AHA's criteria for ideal CV health. These data indicate that further efforts aimed at promoting the LS7 metrics, focusing primarily on diet, could have huge impacts in terms of public health.
