HbA1c is a measure of blood glucose control over the previous two to three months. It is measured as a percentage of total hemoglobin, with normal values ranging from 4% to 6%. In general, for a healthy, non-diabetic adult, an HbA1c of 6.5% or lower is considered to be normal.
For a 60-year-old, the HbA1c level should be at or below 7%. This is because as a person ages, the body's ability to regulate glucose levels decreases, and therefore it is important for older individuals to monitor their blood glucose levels more closely. Additionally, an HbA1c of 7% or higher is a sign of pre-diabetes, and so it is important to ensure that seniors stay within the normal range.
However, it is important to note that HbA1c levels can vary depending on individual health and lifestyle factors, so it is best to speak with a doctor or healthcare provider to discuss what is the most appropriate level for an individual. Additionally, lifestyle changes such as exercising more and eating a healthy diet can help to lower HbA1c levels.
