Introduction:

although the prevalence of childhood obesity (CO) is high globally, there are no composite indices to estimate territorial aspects associated with its risk

Objective:

to develop an obesity risk index (IROBIC) for small administrative units, called “comunas” in Chile

Methods:

we used 2019 data from public sources on children under 10 years living in “comunas” of the two largest regions. IROBIC includes 16 indicators standardized for each “comuna” and grouped together into four domains, determined by principal component analysis (health, socio-economic, built-in and educational environments). IROBIC was calculated as a weighted geometric mean. Differences in obesity risk between the 10 and 5 “comunas” with the highest and lowest IROBIC and of each domain, were calculated with the disparity ratio.

Results:

in spite of the poorest “comunas” having the highest IROBIC, when its value and that for each domain were considered, we observed that the effect of inequality could be mitigated. The 10 and 5 “comunas” with the highest IROBIC have a 2.41 and 4.05 higher risk of CO compared to those with the lowest values

Conclusions:

IROBIC is a useful tool for monitoring the risk of CO and its factors from a territorial perspective.
