Numerous studies have documented the adverse effects of occupational hazards on respiratory functions. The present study hypothesized that: Peak Expiratory Flow Rate (PEFR) of Nigerian premenopausal sanitary workers was neither affected by standing nor sitting: and that neither standing nor sitting PEFR had relationship with Systolic Blood pressure (SBP), Diastolic Blood Pressure (DBP), Mean Arterial Pressure, Body Mass Index (BMI), weight, height and age. In order to test these hypotheses, a population of 48 premenopausal professionals consisting of 24 sanitary workers and 24 teachers were selected after satisfying the inclusion criteria. Measurements were obtained using Wright Flow Meter, Meter Rule, Weighing scale and Sphygmomanometer. The result of the study indicated that the PEFR of the sanitary workers were significantly reduced (P< 0.05) during standing and sitting. Moreover, despite the significant decrease (P<0.05) in SBP, DBP, MAP, BMI and Weight of sanitary workers, only sitting PEFR showed a correlation (r= -0.478, P<0.05) with BMI. Therefore, we concluded that there was postural difference in PEFR of Nigerian female sanitary workers and sitting PEFR related inversely with BMI.
