 Adjusted odds ratios (OR) of major diseases and injuries in the past 12 months and currently by socioeconomic conditions among subjects living on boats

Major diseases/injuries (ICD-10 code)OR (95% CI) in reference to subjects who completed secondary school (n = 298), subjects 15 years and overOR (95% CI) in reference to subjects with occupations not involving boats (n = 620), subjects 15 years and overOR (95% CI) in reference to non-poor† subjects (n = 1418), subjects 5 years and over
Primary school(n = 811)Never went to school (n = 941)Occupation requiring boats (n = 1303)Poor (n = 2319)
*p<0.05; **p<0.01; ***p<0.001. ORs and 95% confidence intervals (95% CI) were adjusted for sex and age. †Non-poor was defined as subjects whose income per family member was 150,000 Vietnamese dong or more.
