Peak Expiratory Flow Rate in Healthy Children from Tehran
Background: Measuring peak expiratory flow rate has been suggested as an important tool in asthma management by all international guidelines. Objective: Studies on various populations have shown considerable variations in normal values of peak expiratory flow rate. Since reference standards for Iranian children are not available, the present study was performed to establish these standards. Me...
متن کاملPeak expiratory flow rate in flour mill workers.
The current cross-sectional study with a comparison group was undertaken to investigate peak expiratory flow rate (PEFR) in flour mill workers and to study relationship between reduction in PEFR and age, smoking, exposure to grain dust and respiratory morbidity. The study included 286 flour mill workers and equal number of neighbourhood controls group-matched for age. PEFR was measured by using...
متن کاملDiurnal variation in peak expiratory flow rate among grain elevator workers.
The diurnal variation (DV) in peak expiratory flow rate (PEFR) has been studied among 132 grain elevator workers who accomplished three daily measurements of PEFR during three weeks. DV was calculated as the difference between the highest and the lowest PEFR as a percentage of the mean PEFR on each day. For the whole group the median was 5.9%. DV was higher among smokers and among workers with ...
متن کاملPeak expiratory flow rate in elderly Malaysians.
An epidemiological survey was conducted among 1,414 healthy ambulatory elderly persons aged 55 years and above in the Kuala Langat district, Selangor. The relationship between peak expiratory flow rate (PEFR), demographic variables, socioeconomic status, smoking, alcohol use and respiratory symptoms were examined. The peak expiratory flow declined with age and were lower in women of all ages. S...
متن کاملMalnutrition and peak expiratory flow rate.
In order to assess the effects of malnutrition on the growth of lung function, 376 Indian schoolchildren aged 6-12 yrs were studied. Peak expiratory flow rate (PEFR) was measured with a Wright peak flow meter, and nutritional status assessed by calculation of the percentage predicted height for age (HFA) and weight for height (WFH) using Harvard standards. After standardizing for height and sex...
