title: Lung function indices of children exposed to wood smoke in a fishing port in South-South Nigeria.
abstract: Children in the warm rain forest are at risk of having their lung function compromised by a variety of factors, including smoke from wood fires. A total of 358 children from a fishing port and 400 children living in a farm settlement were tested to determine their peak expiratory flow rate (PEFR), forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), forced expiratory volume in 1 s per cent and forced expiratory flow between 25 and 75%. The values for the PEFR, FVC, FEV1, forced expiratory volume in 1 s per cent and forced expiratory flow between 25 and 75% of the subjects were significantly lower than those of the controls (P value for males = <0.001, 0.01, 0.002, 0.01 and <0.001, respectively, whereas for their female counterparts = <0.001, 0.003, 0.001, 0.04 and <0.001, respectively). These deficits were observed to be more with increasing duration of exposure to wood smoke for PEFR, FVC and FEV1. Chronic exposure to fish drying using firewood can impair lung function in children. There is a need for alternative methods of fish preservation for those engaged in fish drying.
