It was a retrospective cohort study done on department of paediatrics and department of gynecology & obstetrics, Dhaka Medical College Hospital, Dhaka from January 2009 to December 2010. A total of 340 mother-neonate pairs were included in the study. ⋯ Frequency of spontaneous abortion, stillbirth, preterm delivery and LBW baby in case & control groups was assessed. Smokeless tobacco used by mothers for >5 years had significant association with spontaneous abortion (p<0.01), stillbirth (p<0.01), preterm delivery (p<0.001) & LBW baby (p<0.001) and carries a risk of having spontaneous abortion, stillbirth, preterm delivery & LBW 2.2 times, 2.1 times, 2.9 times & 3.3 times respectively more than non users of smokeless tobacco.

Low back pain (LBP) is a common problem affecting 70% of the population in the developed countries and prevalence is also increasing in the developing countries. We conducted a clinic based cross-sectional study in the city of Dhaka and Chittagong during the period of January 2009 to December 2011. Participants (n=357) were interviewed and examined through a structured questionnaire after a non purposive sampling to explore the influence of body mass index (BMI) on LBP. ⋯ Statistically the association of LBP with BMI was found to be highly significant (p<0.0001). In this study, 137(46.78%) participants of normal BMI presented with LBP but majorities (n=82) presented with mild LBP and overweight and obese participants mostly presented with severe LBP. On the basis of these findings, careful evaluation of risk factors and deliberate assessment of the therapeutic as well as preventive measure for the management of patient of LBP is highly recommended.
