A new study shows that having a low social status can be bad for our health. The study was on monkeys. Researchers from Duke University in the USA looked at the behaviour and health of 45 female monkeys and found that those with a lower social status had more health problems. The monkeys were split up into five groups of nine. The researchers gave the monkeys in each group time to get to know each other. Then they took one monkey from each group and put her into another group. This meant she was the “new girl” and was at the bottom of the group. When scientists checked the health of the monkeys, they found that the “new girl” was unhealthier than the other monkeys.
