Viral hepatitis is a major public health problem in China.
Hepatitis A infections represent a substantial proportion of these, particularly in urban centres.
Little is known about the social and behavioural factors in the urban household environment that influence the transmission of hepatitis A. Methods.
We conducted a register-based case-control study to investigate the risk factor patterns for hepatitis A in the general population of the City of Wuhan, in the PR China.

Home-based interviews combined with household observation were performed to obtain information on social, behavioural and economic risk factors and the household's indoor and outdoor environment.
Analysis included conditional logistic regression.
Hepatitis A infection was associated with a variety of social and household-related factors, like handwashing habits (after working in the garden : adjusted odds ratio [OR]=8.24,95% confidence interval [CI] : 1.5-44.2, before food preparation : OR=4.68,95% CI : 1.8-12.0 ; before eating : OR=4.92,95% CI : 1.5-15.7), and the source of fresh vegetables (OR=3.90,95% CI : 1.6-9.8).
Hygiene in the kitchen and the household surroundings and the disposal of children's stools in vegetable gardens or refuse pits were significantly associated in the univariate analysis only. (...)
