New research shows that one of the best ways to improve mental health in later life is through volunteering. According to researchers at Columbia University, those who volunteer are 43% less likely to develop symptoms of depression. Volunteering provides social interaction and a sense of purpose, leading to increased life satisfaction.
As the global population ages, with an estimated 1.4 billion people over the age of 60, depression has become a serious health concern. Depression in older adults increases the risk of chronic diseases such as diabetes, cardiovascular disease, and high blood pressure.
In the United States, it is estimated that the rate of depression for people aged 65 and older will be 18.4%. The study found that the 65-69 age group had higher rates of depression compared to the 70-74 age group.
Senior author Dr. Guohua Li attributes the higher rates of depression in the 65-69 age group to significant life changes around retirement age. Volunteering and marriage were found to be important factors in preventing depression, while a history of mental health issues increased the risk of developing depression.
Income also played a role, with those earning over $50,000 annually at lower risk of experiencing depression. The study surveyed approximately 3,000 participants in the United States but lacked diversity in terms of gender and income levels.
