“…There are only a few studies investigating the relationship between BMI (including height and weight) and nasal cavity geometry, airflow rate and resistance [1,7,15]. According to our study and other published data, it seems neither resistance nor nasal cavity size changed with increasing BMI [7,15].…”

“…Findings by Crouse and Laine-Alava suggested that adults with high relative body mass have an increased demand for oxygen and thus may have to breathe with higher frequency or more larger volumes during each inspiration [1]. In addition, an increased relative body mass index (BMI) is related to increased oral and nasal pressures, as well as an increased nasal airflow rate.…”

It has been reported that nasal airflow rate and pressure increased with increasing body mass index (BMI). The purpose of this study is to determine if with an increased BMI, the nasal cavity geometry as measured by acoustic rhinometry (AR) increased in healthy adult Singaporeans. This is a population based study. Seventy-three healthy volunteers, 44 males and 29 females aged 18-64 years (mean 34.9 years) were selected. Their BMI was calculated from height and weight measurements. AR was used to measure the minimum cross-sectional area 1-5 cm from the nostril, cross-sectional area at 3.3 and 4 cm and volume 1-5 cm from the nostril of the nasal cavity. There was no statistically significant correlation between BMI, height and weight with all AR measurements. Our study demonstrates that nasal cavity geometry is not affected by increasing BMI, as well as height and weight individually, of healthy adult Singaporeans. Our study indicates that subject with obesity is potentially facing a long-term physiological risk for insufficient air-exchange, or burden of increasing the respiratory rate and/or volume of each breath.

“…American Indians showed lower forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV1) values than American whites [5]. Lower lung volumes and capacities [6] as well as flow rates [7] have been recorded from females compared with males. An inverse relationship between age and lung function values is present in adults and a direct relationship is found with height and weight [8].…”

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

“…Our earlier studies have shown that when individuals with acute nasal congestion due to infections or the acute phase of upper airway allergies are excluded, factors included in the medical history related to general health; nasorespiratory diseases and symptoms; status of the adenoids and tonsils; and smoking habits are associated with measurements of rest breathing in older adults but not in children or adolescents. 21,22 Therefore, information in the medical history was not included in the analyses of this study on 8-17-year-olds. Findings on the association between body size and respiratory variables are contradictory.…”

Objective: To study upper airway breathing in 115 children annually from 8 to 17 years of age with the hypothesis that upper airway respiratory needs increase steadily during growth and show sexual dimorphism. Material and Methods: To calculate nasal resistance, airflow rate (mL/s) and oronasal pressures (cmH 2 O) were measured during rest breathing in a seated position using the pressure-flow technique.Results: Median values of oronasal pressure ranged at different ages in girls from 0.88 to 1.13 and in boys from 0.92 to 1.44 cmH 2 O, being 0.95 and 0.93 cmH 2 O at the age of 17 years, respectively. The gender differences were statistically significant in four age groups (P , .05 by the Mann-Whitney test). Mean values of nasal resistance decreased from 8 to 17 years of age in girls from 4.0 (63.27) to 2.4 (62.30) and in boys from 3.3 (62.48) to 1.5 (60.81) cmH 2 O/L/s. However, there was an increase in resistance in 11-year-old girls and 12-year-old boys and at the age of 15 in both genders (P , .05 by paired t-test). Conclusions: Respiratory efforts stabilize oronasal pressure to maintain vital functions at optimal level. Nasal resistance decreased with age but increased temporarily at the prepubertal and pubertal phases, in accordance with other growth and possibly hormonal changes. When measuring upper airway function for clinical purposes, especially in patients with sleep apnea, asthma, allergies, cleft palate, or maxillary expansion, the measurements need to be compared with age-and genderspecific values obtained from healthy children.

Effects of Age, Body Mass Index, and Gender on Nasal Airflow Rate and Pressures

Abstract: This study suggests that, on the contrary to the findings in children and adolescents, BMI and gender should be taken into consideration when measuring the patency of upper airway in adults.
