“Sickenin’ in the rain” – increased risk of gastrointestinal and respiratory infections after urban pluvial flooding in a population-based cross-sectional study in the Netherlands

Table 2 Health complaints of individual participants and the association with exposure to pluvial floodwater

	Without exposure N = 550	With exposure N = 608	OR	aOR	Children without exposure N = 95	Children with exposure N = 81	OR	aOR	Adults without exposure N = 455	Adults with exposure N = 527	OR	aOR

Note: There were no children without contact with the floodwater, but with AGE, leading to a too small number of outcome events to perform the univariate analysis. Furthermore, there were not enough children to prevent the same from happening in the multivariate analyses for contact with the floodwater and ARI
^aAdjusted for age, sex, summer, having a chronic disorder or disease of the gastrointestinal tract, having reflux, having a food allergy or pregnancy with vomiting during the study period
^bAdjusted for age, sex, summer, having hay fever and having lung anomalies (e.g. asthma, chronic obstructive pulmonary disease - COPD, etc.)
