Background: The most known cause of deaths globally is primary respiratory diseases which usually include pneumonitis, pulmonary hypertension, asthma, chronic bronchitis and other disorders related to respiration in which lungs are affected in multi system diseases. SLE is the most common multi system disease in which many internal organs are affected altogether.

Objective: To determine the correlation of anthropometric Parameters with Pulmonary Function in healthy adults.

Methodology: Data was collected by using convenient sampling. The healthy adults were selected and then divided into two groups depending upon gender then each group was subdivided into sub-groups depending upon the BMI and Waist circumference. The data analysis was done by using SPSS version 25. Shapiro Wilks test were used to assess the normality of data. In order to find out within and across the group difference non-Parametric test was applied. The correlation was analyzed by using Pearson correlation and Mann Whitney U test was applied to analysis across the group difference.

Results: FEV1 and FEV1/FVC showed a significant correlation with the anthropometric measurements of our study. Body mass index has a significant negative correlation with FEV1 and FEV1/FVC with P<0.05 and p<0.01 respectively whereas waist circumference has a significant negative correlation with FEV1 and FEV1/FVC in males (p<0.001) but only with FEV1/FVC in females (p<0.001). Though waist circumference in females is positively correlated with FVC, the correlation was not significant (p=0.49).

Conclusion: FEV1 and FEV1/FVC showed significant correlation with the anthropometric measurements of our study.
