1 . Depression（抑郁症）in young adult males, ages 18 or 19, is linked to a 20% greater risk of having a heart attack in middle age, according to a new Swedish study.
The link can be partly explained by poorer stress resilience（抗压能力）and lower physical fitness among teens with mental disorders.
The research included 238,013 men born between 1958 and 1962 who were given examinations in adolescence（青春期）and were then followed into middle age（up to the age of 58 years）. A total of 34,503 men were diagnosed（诊断）with a mental disorder.
The study found that a mental disorder in young adulthond was linked to a higher risk of having heart attack by middle age. Compared to men without a mental illness in young adulthood，the risk of heart attack was 20%higher among men with a diagnosis.
“We already knew that men who were physically fit in adolescence seem less likely to keep fitness in later years if they have low stress resilience,” said study author Dr. Bergh, “Our research has also shown that low stress resilience is also connected with a greater tendency towards bad behavior, such as higher risks of smoking, drinking and other drug use.”
“Better fitness in adolescence is likely to help protect against later heart disease, particularly if people stay fit as they age. Physical activities may also reduce some of the bad effects of stress. Those in poor health could benefit from additional support to encourage exercise and develop plans to deal with stress,” said Bergh.
