Maternal undernutrition is a global public health problem with far-reaching effects for both mothers and infants. Poor maternal nutrition negatively affects fetal growth and development. Both micro and macro-nutrients are required for the physiological changes and increased metabolic demands during pregnancy, including fetal growth and development. Women in Bangladesh have poor diets and are struggling to meet their nutrient requirements, especially during pregnancy and lactation when requirements are higher. Maternal undernutrition during pregnancy is associated with a range of adverse birth outcomes, including stillbirths, preterm births, low birthweight, and small-for-gestational-age (SGA) neonates, all of which remain unacceptably high in Bangladesh.
Social protection provides a promising platform on which to leverage improvements in nutrition at scale, but current evidence on the impacts of social protection on birth outcomes is limited: few studies have been conducted and some of these studies suffer from methodological limitations. The planned study will contribute to filling this knowledge gap. An additional motivation for the study is provided by the recent WHO 2016 Antenatal Care Guidelines. The guidelines call for studies on the effectiveness of alternatives to providing energy and protein supplements to pregnant women (which is recommended in undernourished populations). Studying the effectiveness of providing combinations of food and cash will help build this evidence base. A third reason to conduct the study is that both food transfers and cash transfers are commonly used policy instruments in Bangladesh, and the choice of intervention components to scale up in the CBP will be guided by the findings from this pilot study. The study findings will thus be highly policy relevant.
A three-arm cluster-randomized, non-masked, community-based, longitudinal trial will be used. Groups of pregnant women will be randomly assigned to one of three study arms providing different combinations of cash and food transfers.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Arm 1 - base cash + BCC | Experimental | pregnant women in this arm will receive the standard package (800 BDT each month), and in addition intensive group-based BCC on nutrition with a focus on how to improve their dietary intake during pregnancy |
|
| Arm 2 - base cash + BCC + food | Experimental | pregnant women in this arm will receive the standard package (i.e., arm 1) and in addition a monthly food basket. The monthly food basket will provide 10 kg micronutrient fortified rice, 3.5 kg of lentils, and 1000 ml of oil, valued at 1000 BDT. |
|
| Arm 3 - base cash + BCC + top-up cash | Experimental | pregnant women in this arm will receive the standard package (i.e., arm 1) and in addition a monthly top-up cash of 1000 BDT to be added to the "base" amount that is part of the standard program. |

| Base cash transfer | Other | Program beneficiaries will receive a monthly transfer of 800 BDT. A government-to-person (G2P) payment system will be used, which will transfer cash on a monthly basis. Under this new system, beneficiaries will select one of the following payment channels based on convenience: mobile financial services or through a bank transfer (which women in remote areas could access through agent banking). Each month, women will receive a text message from the government informing her that the money has been credited to her account. |
| Measure | Description | Time Frame |
|---|---|---|
| Gestational weekly weight gain 2nd to 3rd trimester | Women's weekly weight gain will be calculated by differencing women's weight obtained in the second and third trimester and dividing by the number of weeks between both measurements. | Third pregnancy trimester (34 ± 1 wk of pregnancy) |
| Total gestational weight gain by the third trimester | Total weight gain will be calculated by calculating the difference between women's third trimester weight and the weight obtained at the time of the census. | Third pregnancy trimester (34 ± 1 wk of pregnancy) |
| Dietary energy intake and proportion of women below 85% of the estimate energy requirement (EER) | Dietary energy intake will be assessed using a 24-hour recall in the second and third trimester (18). EER will be calculated using each woman's basal metabolic rate (estimated from the woman's age, gender, and current weight), level of physical activity, and pregnancy trimester. Factors of 1.4 for low, 1.7 for moderate, and 2.0 for high physical activity will be used (19). Additional energy requirement for the second and third trimester of pregnancy (340-350 kcal/d and 452-500 kcal/d, respectively, depending on which reference will be used (20,21)) will be added to account for gestational weight gain and increases in basal metabolic rate. | Second and third pregnancy trimester (34 ± 1 wk of pregnancy) |
| Dietary protein intake | The 24-hour recall data will be used to assess women's protein intake. | Second and third pregnancy trimester (34 ± 1 wk of pregnancy) |
| Mean probability of micronutrient adequacy | the mean of the probabilities of adequacy for 11 key micronutrients (iron, calcium, zinc, vitamin A, thiamin, riboflavin, niacin, vitamin B-6, vitamin B-12, vitamin C, and folate) will be calculated using the 24h recall data. The estimated usual intake will be used to calculate the probability that the usual intake was above the EAR during pregnancy (25). |
| Measure | Description | Time Frame |
|---|---|---|
| Gestational weekly weight gain up to the 2nd trimester | Women's weekly weight gain will be calculated by differencing women's weight obtained at the census (before pregnancy) and second trimester and dividing by gestational age in weeks. | Second pregnancy trimester |
| Use of iron-folic acid, calcium, vitamin B complex, and multiple micronutrient supplements |
| Measure | Description | Time Frame |
|---|---|---|
| Program enrollment | enrollment in the MCBP program | Second and third pregnancy trimester (34 ± 1 wk of pregnancy), 2 months postpartum |
| Receipt of program benefits (base cash, food, top-up cash) and participation in BCC sessions |

| Behavior change communication (BCC) | Behavioral | The BCC strategy has two different components:
|
|
| Food basket | Other | The monthly food basket will provide 10 kg micronutrient fortified rice , 3.5 kg of lentils, and 1000 ml of oil, valued at 800 BDT . Assuming a the ration is split equally among the 5 members of an average-sized household in rural Bangladesh and using food composition data for Bangladesh, the food basket is estimated to provide 354 kcal and 11 g of protein per person per day. The food basket will be provided once every month. The individually packaged foods will be distributed at the Union parishad office, community clinic, or another government facility in the first week of each month. The UDW will inform the beneficiaries of the place and time of the food distribution. Recipients will only receive the food when they present their food card. The card will also be used to record receipt of each ration. If beneficiaries cannot attend the food distribution themselves, a designated "nominee" can pick up the ration on their behalf. |
|
| Top-up cash | Other | The monthly top-up cash of 1,000 BDT will be added to the "base" amount that is part of the standard program. For the top-up cash transfer, a person-to-person payment system is used. WFP will contract with one popular mobile banking service (either bKash or Rockets) for the monthly top-up cash transfers. About two weeks after receiving the base cash transfer, women will receive the top-up cash through a mobile account (which can also be used to receive the base cash transfer). A text message will be sent to the beneficiary to inform her that the top-up transfer has been made into her account. |
