More than 20 million infants worldwide, representing 16 per cent of all births, are born with low birth weight, 96 per cent of them in developing countries. Bangladesh having one of the highest incidence rate (21.6%) in the world.The short-term consequences of LBW is 12 times higher perinatal mortality. It is estimated that LBW causes 60 to 80 % of neonatal deaths. For the survivors, the effects are long lasting and largely irreversible. Infants born LBW are at 2-4 times greater risk to develop acute diarrhea, pneumonia or acute respiratory tract infection than their normal birth weight counterparts. Adults born with LBW suffer increased risk of high blood pressure, coronary heart disease (CHD), non insulin dependent diabetes mellitus, obstructive lung diseases, or renal damage.
Genitourinary (GU) infection, as a major risk factor for low birth weight deliveries affecting a very large number of women both in the industrialized and the developing world. In Bangladesh, there was a high incidence of UTI in 21-25 years age group (44.61%). The bottom line for GU infection is that lactobacilli, healthy bacteria lose their dominant. Recently, the protective role of the commensal microbiota has come into focus for its infection-inhibiting function. Lactobacilli that colonize the gastrointestinal tract or vagina can either significantly modulate the colonic microbiota by increasing the number of specific prebiotic bacteria such as lactobacilli and bifidobacteria or reducing undesired intestinal colonization of pathogenic bacteria. Prebiotic like Fructooligosaccharide (FOS) is known to promote growth of normal healthy flora like lactobacilli (LAB). FOS supplementation in early pregnancy improves vaginal or gut microflora with LAB , which will control GU infection and improve pregnancy outcome and promote infant's growth and development

Medical research over the last ten years has identified genitourinary (GU) infection, as a major risk factor for low birth weight deliveries affecting a very large number of women both in the industrialized and the developing world. It is estimated that up to about 1 billion of women are affected annually by urinary infections worldwide. Urinary tract infections (UTI) are also most common bacterial infections during pregnancy. In Bangladesh, there was a high incidence of UTI in 21-25 years age group (44.61%). The bottom line for GU infection is that lactobacilli, healthy bacteria lose their dominant.
The role of normal vaginal micro-biota in urogenital health Recently, the protective role of the commensal microbiota has come into focus for its infection-inhibiting function. Lactobacilli are now the favourite probiotic ("health promoting") bacteria. There are clinical evidence to show that Lactobacillus strains GR-1 and RC-14 were shown to reduce UTI, BV and infections associated with yeast pathogens.
Fructoligosacharride, a prebiotic agent At present, considerable attention is focused on determining ways to increase the number of probiotic microorganisms including lactobacilli that colonize the gastrointestinal tract or vagina. Prebiotics are substances that can either significantly modulate the colonic microbiota by increasing the number of specific probiotic bacteria such as lactobacilli and bifidobacteria or reducing undesired intestinal colonization of pathogenic bacteria by mimicking their attachment sites on the intestinal mucosa.
Design and methods In a, double- blind, placebo- controlled study, 210 early pregnant community women (6-12 weeks gestation) will be randomized to either FOS or placebo, administered orally, 6g/day for 6 months. Vaginal smear and urine samples will be followed for LAB using Nugent's score and to exclude UTI respectively. Birth events including weight will be documented. Stool or nasopharyngeal samples from their infants will be obtained at week-24, 30, and 36 to see levels of LAB. Anthropometry and diseases morbidity will be monitored during infancy.
- Primary: 1. Incidence of LBW (birth weight below 2500 gram)
- Secondary 1. Rate of vaginal and intestinal colonization of LAB and/or GU infection at week 12, 24, 36 gestation and gain in z-score (weight for height, weight for age and height for age) of infant from birth

- 1. Infant birth weight [ Time Frame: just after birth ]Normal Birth Weight is equal or more than 2500 gm and low birth weight is less than 2500gm
- Gestational age [ Time Frame: upto 40 weeks of pregnancy ]
Gestational age measured in weeks from the first day of women's Last menstrual period to the current date.
Delivery before 36 weeks of pregnancy will be considered as premature
- Vaginal colonization of Lactobacillus (LAB) [ Time Frame: at 12, 18 and 30 weeks of gestation ]Collection of vaginal swab to see colonization of LAB and also Nugent score Nugent score less than 7 indicate normal condition and equal or more than 7 indicates Bacterio-vaginal infection
- Intestinal Colonization of LAB [ Time Frame: at 12, 24 and 36 weeks of gestation from pregnant women and at birth from the infant ]Collection of stool to see colonization of LAB
- Rate of Genito-urinary (GU) infection [ Time Frame: at 12, 18, 24 and 36 weeks of pregnancy ]Collection of urine for culture to see any infection. If bacterial colony count >10to the power 5 indicates genito urinary infection
- Gain in Z-score of infant from birth [ Time Frame: from birth to 3 months of age of infant ]According to WHO weight for length and weight for age (50th percentile) reference table
- Incidence of Acute respiratory infection and diarrhoea [ Time Frame: From birth to 3 months of age ]Fever, cough, respiratory distress,chest indrawing etc and passsage of loose stool
