Physical activity and odds of coronary heart disease among Lebanese women

Abstract

Abstract Background It is known that physical activity (PA) is protective against cardiovascular morbidity and mortality. However, few studies have examined the association between PA, sedentary lifestyle and coronary heart disease (CHD) in women. This case–control study investigates the relationship between PA and sedentary behavior on CHD odds in Lebanese women over forty. Methods One thousand five hundred selected Lebanese women (300 cases and 1200 controls) were included between 2018–2019. Cases were hospitalized women newly diagnosed with CHD, whereas the control groups were free of any heart diseases. Data on socio-demographic, lifestyle, cardiovascular factors, PA and sedentary lifestyle were collected. Multivariate logistic regressions, adjusted for covariates, were performed to investigate the association of PA domains and sedentary behavior with CHD. Results A sedentary lifestyle combined with low activity levels increased the odds of CHD. Among cases, 46.7% participated in moderate or vigorous PA against almost 60.3% of controls. 36.3% of coronary patients had more than 10 h/day of sedentary time, with a positive correlation with CHD (adjusted OR: 1.533, 95%CI: 1.046–2.247). Conversely, moderate and high levels (respectively 600–3000 and ≥ 3000 metabolic equivalents [MET]-minutes/week) of domestic/garden PA revealed lower CHD odds (OR: 0.566, 95%CI: 0.396–0.808 and 0.193, 0.065–0.578 respectively). The detrimental influence of sedentary lifestyle appeared to be significantly reversed by weekly moderate PA, especially as weekly sedentary time was less (OR: 0.616, 95%CI: 0.427–0.888/ 6 to10h of sedentary time and OR: 0.537, 95% CI: 0.37–0.779/ ≤ 6 h), and except sedentary time exceeding 10 h daily. Two PA patterns revealed lower CHD odds: transport-related and domestic/garden PA, as early as low amount, even after adjustment for possible confounders. Conclusion The current study highlights the importance of combating sedentary behaviors and engaging in regular, easily accessible PA to reduce the odds of coronary disease among aging women. Therefore, better information regarding the benefits of physical activities such as transportation-related activities or gardening would be helpful in enhancing the prevention of CHD in aging women.
