Abstrakt:	Objective: To evaluate retrospectively the relationship between meteorological factors in Shenmu County, Yulin City, Shaanxi Province, China and the incidence of lower respiratory tract infections in children. Methods: Meteorological data (air temperature, atmospheric pressure, rainfall, hours of sunlight, wind speed and relative humidity) for Shenmu County and medical data from hospitalized patients aged ≤16 years were collected between January 2009 and December 2012. The association between meteorological factors and rate of hospitalization due to lower respiratory tract infections was investigated; the total hospitalization rate was compared with the rate of lower respiratory tract disease-related hospitalizations. Results: The leading bacterial causes of lower respiratory tract infections were Streptococcus pneumoniae and Haemophilus influenzae type B; the main viral cause was respiratory syncytial virus. Lower respiratory tract infection hospitalization rate was significantly correlated with air temperature (R = -0.651), atmospheric pressure (R = 0.560), rainfall (R = -0.614) and relative humidity (R = -0.470), but not with hours of sunlight (R = -0.210) or wind speed (R = 0.258). Using multiple linear regression, lower respiratory tract infection hospitalization rate decreased with a gradual increase in air temperature (F = 38.30) and relative humidity (F = 15.58). Conclusion: Air temperature and relative humidity were major influencing meteorological factors for hospital admissions in children due to lower respiratory tract infections. (© The Author(s) 2015.)
