A new study highlights the importance of addressing harmful behaviors such as smoking, excessive drinking, and physical inactivity at an early age to improve long-term health outcomes. Published in Annals of Medicine (Elevate), the research shows that these negative habits are associated with declines in both mental and physical health by as early as age 36.
The study, conducted by a research team from Finland, followed participants for over 30 years. It tracked mental and physical health from childhood through their early 60s, using data collected at multiple points during their lives (ages 27, 36, 42, 50, and 61). Participants’ mental health was assessed using surveys on symptoms of depression and psychological well-being, while their physical health was measured using a metabolic risk score based on blood pressure, waist size, blood sugar, cholesterol, and other factors.
Key Findings:
Risk Behaviors: Smoking, heavy drinking (more than 7,000 grams of alcohol per year for women and 10,000 grams for men), and physical inactivity (exercising less than once a week) were identified as major risk factors for poor health outcomes.
Impact on Health: Individuals who engaged in all three unhealthy behaviors had poorer mental and physical health than those who did not. Depressive symptoms, metabolic risk scores, and poor self-rated health were all worse among those with these habits.
Long-Term Effects: The study found that engaging in these risky behaviors over the long term had an even stronger association with declines in health, including an increase in depressive symptoms and metabolic risk.
The study’s lead author, Dr. Tiia Kekäläinen, emphasized the importance of addressing these behaviors early in life to prevent the accumulation of health damage that could lead to serious health issues in later years. Dr. Kekäläinen also noted that while the study could not establish cause-and-effect relationships, it suggests that the harmful behaviors may contribute to poorer mental and physical health, and vice versa.
Conclusion:
The research stresses that while it’s never too late to adopt healthier habits, addressing these issues before they can have lasting effects is crucial. With non-communicable diseases like heart disease and cancer being leading causes of death worldwide, adopting a healthier lifestyle can significantly reduce the risk of these conditions and enhance overall well-being as people age. The study suggests that both midlife and early-life changes in lifestyle can benefit long-term health outcomes.
