Sample size: 145 publication Evidence: moderate

Author Information

Primary Institution: Aga Khan University, Karachi, Pakistan

Hypothesis

Is the use of antipsychotics associated with an increase in weight and body mass index (BMI) in the Pakistani population?

Conclusion

Pakistani patients are likely to gain weight during antipsychotic treatment, which may have serious health consequences due to the high prevalence of diabetes in this population.

Supporting Evidence

  • 50% of patients had a BMI in the overweight or higher range at baseline.
  • Patients showed a mean weight gain of 1.88 kg from baseline in 3 months and 3.29 kg in 6 months.
  • 48% of patients showed clinically significant weight gain.

Takeaway

This study found that many patients taking antipsychotic medications in Pakistan gained weight, which can be bad for their health, especially since diabetes is common there.

Methodology

A case note review of patients prescribed antipsychotic medication at a psychiatry outpatient clinic over a 4-year period.

Potential Biases

Potential bias due to the retrospective nature of the study and lack of a control group.

Limitations

The study lacked a control group of patients not taking antipsychotics, and most patients had prior antipsychotic treatment.
