Abstract

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.

Abstract

On one hundred and seven children 3 months to 5 years old who had received BCG vaccination during neonatal period were reviewed with tuberculin test. This study were conducted at the children's and maternity Hospital Sri Ratu Medan for 4 months. They comprised 61 males and 46 females with moderate to well nou­rished. Tuberculin test was seen at 72 hours after the injection. Tuberculin test was said positive if the induration was >5 mm was found. Positive tuberculin test were found on 58 children (54.2%), out of which 49 children (84.5%) were <1 year old and 9 children (15.5%) were 1 year old. Significant difference was found in positive tuber­culin test between child group of <1 year old compared to those of >1 year old (p <0.001). Diameter of induration was between 0-10 mm. Most of the children (51 = 47.7%) were having diameter of 5-9 mm. Median diameter of induration of tuberculin test was significant difference between child group of <1 year with those of >1-2 years, >2-3 years, >3-4 years and >4-5 years old respectively (p<0.01). BCG scar did not show significant relationship with tuberculin test result and age.
