In a prospective hospital based study, during the period from Jan 95 to Dec 96, 3100 consecutively delivered live newborns were studied for the incidence of low birth weight neonates and to evaluate the associated risk factors. One thousand fourteen newborns were classified as low birth weight babies. The incidence expressed per 1000 live births was 327 (32.7%). Of these, 815 (80.4%) were small for gestational age neonates and 199 (19.6%) were preterm neonates. Five hundred seventy small for gestational age neonates (70%) were weighing between 2001 to 2500 gms. Mothers belonging to the age group of 19-25 years delivered the maximum number of low birth weight babies (618/1014) and ofthese 82.8% were small for gestational age neonates. There were 48 neonates with low birth weight born to mothers below the age of 18 years. Primiparous mothers were found to contribute higher number of low birth weight neonates (414/1014). Spacing as a factor did not show any major difference. Two hundred sixty two low birth weight neonates were born to mothers with significant obstetrical problems such as pregnancy induced hypertension, bad obstetrical history and premature rupture of membranes. The incidence of 32.7 % of low birth weight babies is high enough to ring alarm bells. ; 54: 191-195 MJAFII998

One hundred, non-consecutive, non-randomized, cases of tuberculosis divided in 2 groups i.e. Group A including 50 BCG vaccinated children and Group B including 50 unvaccinated children were studied to determine the pattern of tuberculosis and the role of protein energy malnutrition in the pathogenesis of tuberculosis. Thirty four per cent of Group A and 52 per cent of Group B had severe protein energy malnutrition. Sixty eight per cent in Group A and 76 per cent in Group B had intrathoracic forms of tuberculosis. Twelve (24%) patients in Group A and 11 (22%) in Group B suffered from serious forms of tuberculosis including tubercular meningitis, miliary tuberculosis and disseminated tuberculosis. The difference was not statistically different (p>0.05). However, in severe form of tuberculosis, the morbidity in vaccinated group was less. Sixty six per cent of vaccinated children with disseminated forms of tuberculosis had features of severe protein energy malnutrition. BCG is not effective in preventing tubercular infection in children of preschool age. It is effective to a certain extent in localizing the infection to a particular organ. Severe protein energy malnutrition is a contributing factor in the genesis of tuberculosis in preschool children vaccinated with BCG at or immediately after birth.
