Table 5 MIS 3R 2007: Multi-variable logistic regression analysis of association between individual use of net and explanatory factors

From: Factors associated with mosquito net use by individuals in households owning nets in Ethiopia

Model* Risk factors   Odds Ratio 95% CI p-value p-value test for trend (> 2 categories)
I Age (years) 5-24 0.3 0.2-0.4 < 0.001  
   25-49 1.1 0.8-1.5 0.474  
   50+ 1.2 0.7-2.0 0.415  
  Gender (Female)   1.3 1.1-1.6 0.001  
  Proportion of good nets in household Some (1-99%) 1.8 1.2-2.8 0.006  
   All (100%) 1.6 1.2-2.1 0.003  
  Proportion of nets older than 12 m Some (1-99%) 0.9 0.5-1.6 0.781  
   All (100%) 0.5 0.3-0.7 < 0.001  
  Number of sleeping spaces in HH (per additional space) 0.6 0.5-0.7 < 0.001  
  Net density ≥ 0.5 < 1.0 2.0 1.5-2.7 < 0.001 Ptrend = 0.001
   ≥ 1.0 2.0 0.9-4.2 0.077  
  Altitude ≥ 1000- ≤ 2000 m 1.4 0.9-2.4 0.142 Ptrend < 0.001
   > 2000 m 0.5 0.3-1.0 0.068  
  Urban clusters   2.5 1.5-4.1 < 0.001  
II** Malaria knowledge mean score (terciles) 2-4 1.6 1.2-2.2 < 0.001 Ptrend < 0.001
   ≥ 5 2.4 1.4-2.4 < 0.001  
  School attendance Yes 1.1 0.8-1.5 0.719  
  1. *Model I assessed independent risk factors in all 14,663 participants (in 3,353 households owning nets). Model II assessed effect of household women's knowledge and school attendance in 12,803 participants (in 2,701 of these households where women of reproductive age completed malaria knowledge questionnaire) adjusting for the effects of independent risk factors from model I.
  2. **Test for interaction between malaria knowledge and school attendance did not reveal any statistically significant effects (Wald Test p-value = 0.781)
