Background. Cement dust inhalation is associated with deleterious health effects. The impact of cement dust exposure on the peak expiratory flow rate (PEFR), liver function, and some serum elements in workers and residents near cement factory were assessed.Methods. Two hundred and ten subjects (50 workers, 60 residents, and 100 controls) aged 18–60 years were studied. PEFR, liver function{aspartate and alanine transaminases (AST and ALT) and total and conjugated bilirubin (TB and CB)}, and serum elements{lead (Pb), copper (Cu), manganese (Mn), iron (Fe), cadmium (Cd), selenium (Se), chromium (Cr), zinc (Zn), and arsenic (As)}were determined using peak flow meter, colorimetry, and atomic absorption spectrometry, respectively. Data were analysed using ANOVA and correlation atp=0.05.Results. The ALT, TB, CB, Pb, As, Cd, Cr, Se, Mn, and Cu were significantly higher and PEFR, Fe, and Zn lower in workers and residents compared to controls (p<0.05). Higher levels of ALT, AST, and Fe and lower levels of Pb, Cd, Cr, Se, Mn, and Cu were seen in cement workers compared to residents (p<0.05). Negative correlation was observed between duration of exposure and PEFR (r=-0.416,p=0.016) in cement workers.Conclusions. Cement dust inhalation may be associated with alterations in serum elements levels and lung and liver functions while long term exposure lowers peak expiratory flow rate.

Background: Numerous industries have researched the effects of occupational dust and particles on respiratory function. The continuous exposure to dispersed particles causes respiratory ailments in spice mill workers. Spice dust exposure is linked to a systemic inflammatory response, including respiratory irritation. Spice dust is finely divided solid particles and a form of respirable dust this is the leading cause of occupational disease. Allergies and asthma have been linked to spice mill workers. Objective: To study the effect of spice dust exposure on expiratory function and to compare the peak expiratory flow rate of spice mill workers and normal adults across age groups and gender Method: 186 subjects in Mumbai region, 93 spice mill workers and 93 normal adults were selected as per inclusion and exclusion criteria. PEFR was measured in all the participants using a mini Wright peak flow meter. Result: The statistical analysis showed that there is a significant difference in the peak expiratory flow rates of spice mill workers. However, intergroup analysis between age groups showed that there was not much difference in the PEFR values for the age group 40-50 when compared with normal. The reason could be less number of participants available for the study. Also, the gender-wise comparison showed statistically significant difference in male and female PEFR values. Conclusion: The present study concluded that peak expiratory flow rate was significantly reduced in spice mill workers when compared to normal adults of same age. Key words: PEFR, spice mill workers, spice dust, allergies.

Obesity has become one of the major health issues in India. WHO defines obesity as “A condition with excessive fat accumulation in the body to the extent that the health and wellbeing are adversely affected”. Obesity results from a complex interaction of genetic, behavioral, environmental and socioeconomic factors causing an imbalance in energy production and expenditure. Peak expiratory flow rate is the maximum rate of airflow that can be generated during forced expiratory manoeuvre starting from total lung capacity. The simplicity of the method is its main advantage. It is measured by using a standard Wright Peak Flow Meter or mini Wright Meter. The aim of the study is to see the effect of body mass index on Peak Expiratory Flow Rate values in young adults. The place of a study was done tertiary health care centre, in India for the period of 6 months. Study was performed on 80 subjects age group 20 -30 years, categorised as normal weight BMI =18.5 -24.99 kg/m2 and overweight BMI =25-29.99 kg/m2. There were 40 normal weight BMI (Group A) and 40 over weight BMI (Group B). BMI affects PEFR. Increase in BMI decreases PEFR. Early identification of risk individuals prior to the onset of disease is imperative in our developing country. Keywords: BMI, PEFR.
