Health impact of the Tajogaite volcano eruption in La Palma population (ISVOLCAN study): rationale, design, and preliminary results from the first 1002 participants

Table 4 Association of place of residence on the general population (western vs. eastern region) in acute symptomatology during the eruption of the volcano. Logistic regression

Acute symptoms	OR (CI 95%) (western vs. east region)	p	OR_a (CI 95%) (western vs. east region)	p
Lower respiratory tract (Cough, Dyspnea, Wheezing)	2.03 (1.42–2.92)	< 0.001	1.99 (1.33–2.99)*	0.001
Depression/anxiety	2.58 (1.82–3.66)	< 0.001	1.95 (1.30–2.93)**	0.001
Insomnia	2.88 (2.02–4.10)	< 0.001	2.03 (1.33–3.09)**	0.001
Ocular	1.40 (1.01–1.94)	0.043	1.33 (0.91–1.96)**	0.140
Headache	1.72 (1.18–2.51)	0.005	1.26 (0.80–1.97)**	0.321
Nasal/ear	1.74 (1.21–2.50)	0.003	1.51 (0.99–2.28)**	0.053

OR: odds ratio; OR_a: adjusted odds ratio; CI: confidence interval
