Certain community factors impacted HbA1c change and reduced treatment intensification effectiveness in people with diabetes in a study involving >15,300 individuals. Participants had type 2 diabetes with an HbA1c ≥7.5% at baseline. Investigators looked at how specific community factors impacted HbA1c change over 6 and 24 months. Among the results:
- HbA1c was lowered by an average of 0.07% over 6 months in areas with high community socioeconomic deprivation (CSD).
- Reductions were 0.10% greater in areas with the best vs worst food availability.
- Reductions were ~0.18% greater in areas in the second and third quartiles of utilitarian physical activity favorability, vs those in the first quartile.
- Treatment intensification had less of an impact on 6-month HbA1c change in areas with the worst vs best CSD.
- Treatment intensification had less of an impact on 24-month HbA1c change in areas with the worst CSD, vs those in the third quartile.
- It was strongest in areas most favorable for utilitarian physical activity (vs the worst).
