OBJECTIVE :The objective of the study is to determine the effect of various environmental factors associated with modern lifestyle,on sleep patterns of three different age groups through a survey based study. METHODSThis was a survey based cross sectional study. A questionnaire which included questions about their lifestyle habits such as caffeine consumption, electronic media or gadget usage, bedtime and wake up time were distributed to people of different ages who were grouped into three age groups. The data collected was then analyzed statistically.  RESULTSMost of the habits of today's sedentary lifestyle such as excessive stimulant consumption and extensive late night usage of electronic media and gadgets have a negative impact on both quality and quantity of sleep. People with such habits tend to have a very short and disturbed sleep. From the current study, it is clearly evident that the group which is most affected are the adolescents. CONCLUSIONAwareness regarding the ill effects of these modern day lifestyle factors would help everyone to minimise the adverse effects of these factors on sleep and aid in adopting a healthy lifestyle.

Objectives: The main aim of this study is to compare the oronasal and nasal spirometry among adenoid hypertrophy children before and after surgery.Methods: A total of 40 healthy and 40 adenoid hypertrophy children were recruited for this study with the age range from 6 to 15 years. All the children were examined by two measurements (1) oronasal spirometry and (2) nasal spirometry. Forced vital capacity (FVC), forced expiratory volume in 1 s (FEV 1), FEV 1/FVC%, forced expiratory time (FET), peak expiratory flow rate, peak inspiratory flow rate (PIFR), and forced expiratory flow (FEF)25-75, FEF25%, FEF50%, FEF75%, FIF25%, FIF50%, and FIF75% were recorded.Results: All the parameters were significantly reduced in adenoid hypertrophy by nasal spirometry when compared to oronasal spirometry. FEV1/ FVC% was insignificant from oral to nasal values among adenoid hypertrophy in both the sexes. FET can act as an indicator for upper airway obstruction which shown significantly in adenoid hypertrophy but insignificant among control and adenoidectomy. Inspiratory parameters also had shown more variation in nasal than oronasal spirometry.Conclusion: Significant differences were found in many parameters between oronasal and nasal spirometry among adenoids and adenoidectomy. Nasal spirometry is a portable one, simple, and less cost-effective and so it can be used to determine the obstruction in the nose nasopharynx region.
