Belfast researchers looked at data on the number of anti-obesity medications prescribed in Northern Ireland over an eight year period. The centralised collection of GP prescriptions covered a population of approximately 1.75 million people.
Significant seasonal variation in the number of antiobesity medication prescriptions was found. There was a difference of 8% between the peak of prescribing and the trough, with the peak occurring in late June and early July. The seasonal variation was different depending on gender, with women demonstrating a difference of 11% between the peak and the trough, compared to 3.5% in men.

The authors concluded that the presence of prescribing cycles for antiobesity medication suggests that ‘patients consulting in the spring and early summer could offer numerous teachable moments’ with regard to weight loss
