Abstract
OBJECTIVE: The primary aim of our study was to assess the variation of PEFR with various medical students of Karachi, PakistanDESIGN: Cross-sectional studySetting: Medical students of Karachi Medical and Dental CollegeParticipants: 276 non-smoker healthy medical students composed of 168 females and 108 males.VARIABLE PARAMETERS: They include mean age, body height and body weight and PEFR. They were marked separately for each genderRESULTS: The mean waist hip ratio in females was observed to be 0.843±0.111in relation with that of mean PEFR value 452.97±65.84 L/min, whereas in males the mean waist hip ratio was 0.864±0.028 in relation with that of mean PEFR value 445.93±66.49 L/min. Also there is a statistically significant variation in PEFR with an increase in waist hip ratio. The mean height of males was 173.63 ±7.5 cm and weight was 61.81 ±11.25 Kg while mean height of females was 158.56±7.3 cm and weight was 49.33±9.04 Kg. PEFR is positively correlated with increase in height and weight up to a certain limit.CONCLUSION: The study concludes that PEFR is affected positively by variation in waist hip ratio; moreover young females have more waist hip ratio and PEFR values than their young male counterparts. A large sample size with accurate peak flow meter is required along with ethnic consideration of the study population for better, accurate and clear results
