Background Children in household contact of adults with smear-positive tuberculosis (TB) are at higher risk of TB infection. Screening of these children is a main strategy for eliminating childhood TB.Objective To determine risk factors of TB among children in household contact with smear-positive adult TB patients.Methods This case-control study was conducted in 5 public health centers at Batu Bara District, North Sumatera. We studied children from birth to 18 year-old living in the same house as adults with smear-positive TB. A tuberculosis scoring system was used to diagnosis TB in the children. Associations between risk factors and the incidence of TB were analyzed using Chi-square, Mann-Whitney U, and logistic regression tests.Results We enrolled 145 children who had household contact with smear-positive adult TB patients. Subjects were allocated to either the case group [TB score >6; 61 subjects (42.0%)] or the control group [TB score <6; 84 subjects (58.0%)]. Bivariate analysis revealed that nutritional status, immunization status, number of people in the house, sleeping in the same bed, and duration of household contact had significant associations with the incidence of TB. By multivariate logistic regression analysis, nutritional status and duration of household contact were significant risk factors for TB, with OR 5.89 and 8.91, respectively.Conclusion Malnutrition and duration of household contact with smear-positive adult TB patients of more than 6 hours per day were risk factors for TB among children.
Background Obesity has been associated with respiratory complications and it is believed to reduce lung volume. Obesity imposes additional stress on ventilation during exercise and may even result in pulmonary function impairment. Exercise induced-bronchospasm has also been found in obese children. Lung function tests can be useful to confirm diagnosis, response to therapy, or prediction of lung and respiratory diseases. The peak flow meter is an inexpensive, practical way to measure lung function, and can detect the early warning signs of a decrease in lung function. Objective To compare the peak expiratory flow rate (PEFR) before and after physical exercise in obese and non-obese primary school Methods A quasi-experimental study using the one group pretestth th th percentile) using a mini-Wright peak flow meter to evaluate the PEFR before and after eight minutes of physical exercise. Height, weight, body mass index, and physical status were determined before testing. Results PEFR between obese and non-obese children was significantly ConclusionThe PEFR for obese children is significantly lower than non obese children even before physical exercise.

A retrospective study was done on patients with bronchopneumonia hospitalized at the Dr. Pirngadi Hospital Medan/School of Medicine, University of North Sumatera; during January 1985 through December 1989. The purpose of this study is to assess the morbidity and mortality of bronchopneumonia with measles and the nutritional status of the patients. Out of the 14.082 patients admitted, 1310 children suffered from bronchopneumonia (10.7%). Ninety nine of them were also with measles (7.6%). Most of the patients with bronchopneumonia without measles were in the age group 0-1 year (58.7%). The mortality waas 24.8% and the highest mortality rate was in the age group of 4-5 years (34.6%). Most of the patients with bronchopneumonia and measles were in the age group of 1-2 years (30.3%). The mortality rate of bronchopneumonia with measles was 22.2% and the highest mortality rate was in the age group of 3-4 years (35. 7%). Bronchopneumonia with or without measles occurred more in malnourished patients rather than in well-nourished cases. All of the patients who had bronchopneumonia with measles in the present study had never been immunized against measles.
Background Tuberculosis (TB) and cigarette consumption are relatively high in Indonesia. Passive smoking may increase the risk of infection and disease in adults and children exposed to TB. An association between passive smoking and Mycobacterium tuberculosis infection in children has not been well documented. Objective To assess for an association between passive smoking and M. tuberculosis infection in children who had household contact with a TB patient. Methods This cross-sectional study was conducted in February and March 2011. Children aged 5 to 18 years who had household contact with a TB patient underwent tuberculin testing for M. tuberculosis infection. Subjects were divided into two groups: those exposed to passive smoke and those not exposed to passive smoke. Chi-square test was used to assess for an association between passive smoking and M. tuberculosis infection. Results There were 140 children enrolled in this study, with 70 exposed to passive smoke and 70 not exposed to passive smoke. Prevalence of M. tuberculosis infection was significantly higher in the passive smoking group than in those not exposed to passive smoke [81.4% and 52.9%, respectively, (P= 0.0001)]. In the passive smoking group there were significant associations between nutritional state, paternal and maternal education, and M. tuberculosis infection. But no associations were found between M. tuberculosis infection and familial income or BCG vaccination. Conclusion Among children who had household contact with a TB patient, they who exposed to passive smoke are more likely to have M. tuberculosis infection compared to they who not exposed to passive smoke.
