Background Obesity has been associated with respiratorycomplications and it is believed to reduce lung volume. Obesityimposes additional stress on ventilation during exercise andmay even result in pulmonary function impairment. Exerciseinduced-bronchospasm has also been found in obese children.Lung function tests can be useful to confirm diagnosis, responseto therapy, or prediction of lung and respiratory diseases. Thepeak flow meter is an inexpensive, practical way to measure lungfunction, and can detect the early warning signs of a decrease inlung function.Objective To compare the peak expiratory flow rate (PEFR) beforeand after physical exercise in obese and non-obese primary schoolboys aged 6 to 12 years old.Methods A quasi-experimental study using the one group pretest-posttest design was performed on 30 obese children (BMI abovethe 95<h percentile) and 30 non-obese children (BMI betweenthe 5<h - 85'h percentile) using a mini-Wright peak flow meterto evaluate the PEFR before and after eight minutes of physicalexercise. Height, weight, body mass index, and physical statuswere determined before testing.Results The PEFR before and after exercise were 14.80 for obesechildren and 9.76 for non-obese children. The mean value forPEFR between obese and non-obese children was significantlydifferent (P<0.05).Conclusion The PEFR for obese children is significantly lowerthan non obese children even before physical exercise.

Management Of Dysphagia

Purpose: Voluntary cough dysfunction is highly prevalent across multiple patient populations. Voluntary cough has been utilized as a screening tool for swallowing safety deficits and as a target for compensatory and exercise-based dysphagia management. However, it remains unclear whether voluntary cough dysfunction is associated with the ability to effectively clear the airway. Method: Individuals with neurodegenerative disorders performed same-day voluntary cough testing and flexible endoscopic evaluations of swallowing (FEES). Participants who were cued to cough after exhibiting penetration to the vocal folds and/or aspiration with thin liquids during FEES met inclusion criteria. One-hundred and twenty-three trials were blinded, and the amount of residue before and after a cued cough on FEES was measured with a visual analog scale. Linear and binomial mixed-effects models examined the relationship between cough airflow during voluntary cough testing and the proportion of residue expelled. Results: Peak expiratory flow rate ( p = .004) and cough expired volume from the entire epoch ( p = .029) were significantly associated with the proportion of aspiration expelled from the subglottis. Peak expiratory flow rate values of 3.00 L/s, 3.50 L/s, and 5.30 L/s provided high predicted probabilities that ≥ 25%, ≥ 50%, and ≥ 80% aspirate was expelled. Accounting for depth of aspiration significantly improved model fit ( p < .001). Conclusions: These findings suggest that voluntary cough airflow is associated with cough effectiveness to clear aspiration from the subglottis, although aspiration amount and depth may play an important role in this relationship. These findings provide further support for the clinical utility of voluntary cough in the management of dysphagia.

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.
