Question

Question #: 14
BACKGROUND: Limited information is available on the health behavior profile of patients with premature acute coronary syndrome (ACS). The purpose of this study is to describe the health behavior of young patients with ACS at the baseline and 1 year post-ACS and examine sex differences.
METHODS: GENESIS-PRAXY is a prospective study of adults (18-55 years old) hospitalized with ACS from 26 centers located in Canada, United States, and Switzerland. Data on diet, physical activity, smoking, alcohol consumption, and recreational drug use were collected through self-administered questionnaires at baseline and 1 year post-ACS.
RESULTS: Our analysis included 740 patients with complete data. At baseline, the health behavior profile of young patients with ACS was worse than that of the general population. Men had a lower fruit and vegetable intake, consumed alcohol more, and used recreational drugs more than women. Conversely, fewer men than women were smokers (34% vs 42%). At 1 year post-ACS, the proportion of those consuming ≥5 daily servings of fruits and vegetables increased modestly (+5% vs +1%, for men vs women) but remained lower than the general population. Among women, the prevalence of smoking remained about twice as high as the general population. Recreational drug use also remained higher than in the general population.
CONCLUSIONS: Despite small improvements at 1 year post-ACS, the health behavior profile of young patients remained worse than that of the general population. Greater efforts to improve health behaviors post-ACS among young patients are needed, and a sex-based approach may be required to ensure successful behavioral changes.

Answer 1

ANSWER 1: A PROSPECTIVE COHORT STUDY

A prospective cohort study is a longitudinal cohort study that follows over time a group of similar individuals (cohorts) who differ with respect to certain factors under study, to determine how these factors affect rates of a certain outcome.
