Children in HIC

Prevalence of childhood obesity

19 out of 45 studies found higher obesity prevalence rates among those with low SES (all indicators), 12 studies found no and 14 varied associations.

High

15 out of 20 studies found higher obesity prevalence rates among those with low education, 1 study found no, and 4 varied associations.

5 out of 13 studies found higher obesity prevalence rates among those with low occupation, 6 studies found no, and 2 varied associations.

4 out of 11 studies found higher obesity prevalence rates among those with low income, 3 studies found no, and 4 varied associations.

2 out of 5 studies found higher obesity prevalence rates among those with low SES (composite measures), 1 study found no, and 2 varied associations.

2 out of 7 studies found higher obesity prevalence rates among those with low neighbourhood SES, 3 studies found no, and 2 varied associations.

General population in HIC

Prevalence or incidence of overweight and obesity in later childhood/life

5 studies showed no direct or a small influence of education on later childhood overweight and obesity, 2 studies showed an increased risk for overweight and obesity in the lowest education strata.

High

No or small associations between occupation and overweight or obesity were found in 4 studies, of which 2 reported on adult overweight and obesity. 2 studies reported an increased risk of later childhood overweight and obesity in the lowest occupation strata.

3 studies observed effects regarding income discrepancies and later childhood overweight and obesity, 2 studies showed no associations.
