Status Recruiting

Clinical Trial Summary

The objective of the research project is to establish an evidence-based sustainable nutrition service delivery platform for optimizing pregnancy weight gain, increasing dietary diversity of adolescent girls, and ensuring proper physical growth of under 2 children. Hypothesis 1. Pregnant Women: Intensive nutrition and WASH counseling, iron-folate, calcium supplementation during pregnancy, can improve gestational weight gain and improve hemoglobin status in pregnant women in a slum of Dhaka city 2. Adolescent girl: Iron and zinc supplementation and nutrition counseling on dietary diversity could improve nutritional status and dietary diversity score in adolescent girls of slums in Dhaka 3. Children <2 years: Counselling on IYCF, growth monitoring, and promotion, ensuring six-monthly vitamin A supplementation, counseling on WASH, treatment of acute malnutrition, and daily 1 egg supplementation for 3 months for severely stunted children can improve the nutritional status of children 4. Counselling to improve Water, Sanitation and Hygiene (WASH) practice: WASH intervention can improve EED biomarkers

Clinical Trial Description

Background 1. Burden: The emergence of COVID-19 poses a substantial public health risk to the world. Our research done at the peak of the lockdown in Dhaka city showed that 90% of more than 200 households surveyed in a slum in Dhaka city and villages of Matlab in rural Bangladesh suffered from food insecurity, the situation was worse in the slum areas. Our previous work demonstrated that 50% of under-five children in slums have stunted growth, half of all children suffer from deficiency of zinc. Our recently completed study revealed that third-trimester weight gain was poor in general among rural women in Matlab, Bangladesh, and 54% of the women failed to gain adequate weight (>4 kg) in the third trimester. 2. Knowledge gap: Although the burden of undernutrition, as well as adverse consequences of nutritional impairment, is prominent in Bangladesh, there is no platform to implement sustainable nutrition delivery services in slums, particularly for children, adolescent girls, and mothers with pregnancy. In addition, there lack of data on the status of pregnancy weight gain, dietary diversity both in pregnant women and adolescent girls in slums. Evidence on the role of Infant and Young Child Feeding (IYCF), growth monitoring and promotion, micronutrient supplementation, and counseling on Water, Sanitation, and Hygiene (WASH) in improving childhood growth and ameliorating Environmental Enteric Dysfunction (EED) is also limited. 3. Relevance: Such lack of knowledge limits the success of nutritional programs being done in slums. Moreover, it is causing obstacles in reducing the nutritional burden among three vulnerable groups of the population. Methods This study will be conducted in the Bauniabadh and the adjacent slum areas of Dhaka city. This study includes a community survey, formative study, community-based nutrition intervention, and an evaluation of the programmatic intervention using a quasi-experimental design. Bauniabadh slum area has a population of ~150,000. It has five blocks: A, B, C, D, and E. Blocks B, C, and E will be the intervention area for programmatic intervention and A and D will be the control area where no intervention will be provided. Blocks A, and D is separated from other blocks by a road, a school, and a water body. At first, a community survey will be conducted to identify the total number of beneficiaries in both the control and intervention areas: under 2 years old children, adolescent girls, and pregnant women at or before 16 weeks of gestation. The formative research includes 24-h dietary recalls, in-depth interviews with purposively selected household heads, women, adolescent girls, and focus group discussions with women and adolescent girls to explore the locally available foods to prepare nutritious diets for pregnant women and adolescent girls. Moreover, this formative study will help in tailoring the messages for group counseling sessions on nutrition and WASH on the perspectives of the slum dwellers in Dhaka city. All counseling materials for the programmatic intervention will be developed from data generated from the formative research and using existing materials. In the intervention area, nutrition intervention will be provided to all pregnant women, adolescent girls, and children under the age of 2 years. For pregnant women, intensive dietary counseling will be provided through household visits. The intervention also includes daily iron-folate and calcium supplementation to the pregnant women for the remaining pregnancy period till childbirth, and at least four antenatal visits to local ANC service providers will be ensured. For all adolescent girls, monthly two nutrition education sessions for six months will be organized to improve dietary diversity. Adolescent girls will also receive weekly iron and folate supplementation for 3 months and 10 mg of zinc sulfate tablet daily for 1 month. Training research staff will do monthly growth monitoring and promotion for all under 2-year-old children. All children suffering from acute malnutrition will be treated and severely stunted children will be supplemented with one egg daily for 3 consecutive months and multiple micronutrient powders for six months. Additionally, counseling on water sanitation and hygiene, and food safety will be provided to all beneficiary households. This program will ensure community participation to improve the garbage disposal system, water supply and cleaning of drains in the area. The primary outcome measures will be total pregnancy weight gain (kg) and rate of weight gain (kg/week) for pregnant women. Change in dietary diversity scores in adolescent girls and change in length-for-age z-score for children under the age of 2 years. Evaluation will be done using a quasi-experimental design. Data related to outcome indicators will be collected from target groups from both the intervention and the controls areas. At the end of the intervention, based on calculated sample sizes to see the changes in outcome variables, at a 5% level of significance with 90% power, we will need to enroll at least 199 pregnant women, 572 adolescent girls, 420 <2 children in each group. Based on previous data, we assume that the total available sample sizes for the programmatic intervention will be 400 pregnant women, 1200 adolescent girls, and 1500 for children <2 years. Therefore, our sample size will have more than enough power to test our hypotheses. ;
