Causal analysis of H1N1pdm09 influenza infection risk in a household cohort.


ABSTRACT:

Background

Obtaining a comprehensive quantitative figure of the determinants of influenza infection will help identify priority targets for future influenza mitigation interventions. We developed an original causal model integrating highly diverse factors and their dependencies, to identify the most critical determinants of pandemic influenza infection (H1N1pdm09) during the 2010-2011 influenza season.

Methods

We used data from 601 households (1450 participants) included in a dedicated cohort. Structural equations were used to model direct and indirect relationships between infection and risk perception, compliance with preventive behaviours, social contacts, indoor and outdoor environment, sociodemographic factors and pre-epidemic host susceptibility. Standardised estimates (?std) were used to assess the strength of associations (ranging from -1 for a completely negative association to 1 for a completely positive association).

Results

Host susceptibility to H1N1pdm09 and compliance with preventive behaviours were the only two factors directly associated with the infection risk (?std=0.31 and ?std=-0.21). Compliance with preventive behaviours was influenced by risk perception and preventive measures perception (?std=0.14 and ?std=0.27). The number and duration of social contacts were not associated with H1N1pdm09 infection.

Conclusions

Our findings suggest that influenza vaccination in addition to public health communication campaigns focusing on personal preventive measures should be prioritised as potentially efficient interventions to mitigate influenza epidemics.
