“…In the case of respiratory parameters, prediction equations obtained from a reference population provide a baseline for evaluating the pulmonary function of a subject, based usually on the person's standing height, age and sex [1]. There are well-documented ethnic, sex, age, geographical, postural, socioenvironmental, occupational and instrumental variations in lung function measures.…”

To determine normal values of respiratory function for Sudanese, a randomized stratified crosssectional study was performed on 2250 healthy Sudanese aged 7-86 years in 2002-05. Data were obtained through a questionnaire, pulmonary function testing and taking anthropometric measurements. Lung function and anthropometric measurements were correlated and regression equations were derived. Sudanese of Arab ethnic background had significantly higher forced vital capacity (FVC), forced expiratory volume in 1 (first) second (FEV1) and peak expiratory flow rate (PEFR) than those of African ethnicity. In adults a positive correlation was found between lung function and height and a negative correlation with age. Gender and ethnic variations in Sudanese lung function were confirmed. Comparisons were made with data from other international studies. These values can be used as reference values in respiratory clinics in Sudan. 1Faculty of Medicine, Imam Elmahdi University, Kosti, Sudan (Correspondence to A.A. Bashir: amirali69@yahoo.com

“…Moreover, there are some differences in the body proportion in children of different ethnic background, particularly the difference in trunk length between the African and the white children (6,7). It has been shown that prediction of lung function indices from sitting height rather than standing height would virtually eliminate the differences between the African and white children (8). Trunk length or sitting height, being the closest approximation of chest size of all the commonly used anthropometric parameters, may be a better predictor of static lung volumes than standing height.…”

As part of a comprehensive evaluation of lung function in Hong Kong Chinese children and adolescents, over a thousand healthy subjects aged 7-19 yr from seven schools were recruited for lung function testing that included spirometry and, in many cases, lung subdivision measurements. Lung function tests were performed using SensorMedics Automated Body Plethysmograph according to published standards. Of these, 551 subjects (219 males), aged 8-19 yr, had satisfactory lung subdivision indices recorded. Analysis for the values of lung subdivisions including total lung capacity (TLC), residual volume (RV), and functional residual capacity (FRC) demonstrated that standing height and sitting height were the best predictors of lung volumes. After allowing for standing height or sitting height in the regression models for lung volumes, age at examination was the second best parameter, although its inclusion into the equations contributed to less than 1% of explained variance for boys and 3% for girls. These are the first reported data in international literature on reference values for lung subdivisions in Chinese children and adolescents.

“…Many equations allow the option of substituting arm span for height for patients unable to stand due to missing limbs, severe scoliosis, or other abnormality. Sitting height has also been used occasionally to derive normalization equations instead of standing height in selected populations [3,4]. Use of sitting height as a predictor of normal lung function may be less prone to variation due to ethnicity and race than use of standing height [4].…”

“…This method has been investigated and found to be sufficient in several populations of different background for patients with osteoporosis or vertebral-fracture-induced changes in height [14][15][16][17]. Another alternative, when reference equations are available, is to use sitting height [3,4]. Any time the calculations are performed using variant methods, a note should be included in the formal PFT report declaring the variance.…”

Pulmonary function testing is useful for the diagnosis and management of a variety of pulmonary conditions, and the most commonly obtained component is spirometry. Spirometry is most useful in the evaluation of obstructive airway disorders but can be a helpful tool in the management of patients with chest restriction or mixed disease. The utility of spirometry depends on reproducibility, standardization, and quality of testing. Accurate interpretation of test results depends on the availability of reference equations applicable to the subject undergoing testing. This paper reviews basic concepts, testing procedures, and interpretation of a single set of spirometry results as well as results obtained over time and gives an overview of previously published reference equations.
