Data Source
This study analyzed the data from the 2017 Bangladesh Demographic and Health Survey (BDHS), administered as a part of the global Demographic and Health Survey program, to assess the impact of quality ANC (qANC) on delivery and PNC. BDHS is a cross-sectional survey implemented by Mitra and Associates and conducted under the supervision of the National Institute of Population Research and Training (NIPROT) and the Ministry of Health and Family Welfare.
Study population and survey design
All the 15-49 years old ever married women who had a pregnancy in last 3-5 years were our study population. And our particular objective was to examine the impact of qANC on delivery and PNC services for mother and child by medically trained healthcare providers within 48 hours of delivery. The survey used a two-stage stratified cluster sampling design to select respondents from households. Samples were collected covering urban (in two stages) and rural (in three stages) areas from all the administrative divisions in Bangladesh: Dhaka, Chottogram, Rajshahi, Sylhet, Barisal, Khulna, Rangpur and Mymensingh. A list of total 650 enumeration areas (EAs) (250 in urban areas and 425 in rural areas) was used as a sampling frame provided by the Bangladesh Bureau of Statistics (BBS) referring to the 2011 Population and Housing Census of the People’s Republic of Bangladesh (BBS 2011). EAs’ were also the primary sampling unit (PSU) covering an average of 120 households. During the first stage of sampling, rural wards were chosen, then PSUs, and finally families were chosen from PSUs. In urban areas, the PSUs method was used to choose wards, and one EA was chosen from each PSU. Then, in the second sampling stage, systematic sampling was implemented to select an average of 30 households per EA to provide statistically reliable estimates of the key demographic and health variables for the whole country, for urban and rural areas separately and for each administrative division. A detailed description of the survey design, methodologies, sample size and questionnaires have been provided in the final summary report of 2017–2018 BDHS (20).
Dependent variable
The main outcomes of our study were qANC, facility delivery, a skilled birth attendant (SBA) conducting the delivery and PNC services for both mother and child within 48 hours of delivery. When a mother has received all the five core components of ANC such as measurement of blood pressure, measurement of weight, blood test for hemoglobin, urine test for albumin, and counselling on maternal danger signs during the antenatal visits; she was considered to receive a qANC. The participants were asked about whether the healthcare providers performed these five components at least once at any ANC visit irrespective of pregnancy trimester, through a recall interview to determine the proportion of qANC among all ANC visits.
Explanatory variables
The explanatory variables included in the study were selected based on previous literatures reporting the quality of maternal and newborn care services and also the structure of BDHS reports. Participants (ever married women of 15-49 years age who experienced a pregnancy within last 3-5 years) reported their age in years (categorized as >19 years, 20-29 years, 30-39 years, 40-49 years), education level (categorized as no education, primary, secondary incomplete, secondary complete/higher), residence (urban, rural), division (Dhaka, Chottogram, Rajshahi, Sylhet, Barisal, Khulna, Rangpur, Mymensingh), wealth quintile, occupational status of the participants and their husbands (not working, agriculture, skilled/unskilled manual, services/sales) and birth order (1, 2-3, 4). Principal component analysis was conducted using data obtained on household construction materials and housing characteristics (i.e., source of water, sanitation facility, housing structure) along with ownership of durable assets to determine the wealth status of households for further determination of socioeconomic status; then the wealth status was stratified into quintiles (richest, richer, middle, poorer, poorest).
Data Analysis
Women aged 15-49 years and having at least one live birth in last 3-5 years were considered as the study population. The number of ever-married women in BDHS 2017 was 47,828. For the analysis, continuous variables mother's age, education, parity and birth order, were converted into categorical variables. The main outcomes of the study were facility delivery, an SBA conducting the delivery, and PNC services for both mother and child within 48 hours of delivery.
In this study, a mother was considered to have received qANC when each of the five recommended components of ANC were provided to the mother at least once at any ANC visit irrespective of pregnancy trimester. These five components include (i) measurement of blood pressure, (ii) measurement of weight, (iii) blood test for hemoglobin, (iv) urine test for albumin, and (v) counseling on danger signs. PNC is referred to as the care provided to the mother and child after the delivery. In this study, we examined the effect of qANC on receiving PNC from a medically trained provider (MTP) within 48 hours after the delivery.
Descriptive statistics were used to assess the sociodemographic characteristics of the targeted population. To evaluate the impact of qANC on PNC and delivery care, generalized linear model with binomial family and log link was fitted. Mother’s age, education, occupation, husband’s occupation, birth order, and wealth quintile were considered as potential confounders based on previous literatures. All associations were considered statistically significant if p value was less than 0.05. Stata 14.0 (StataCrop. 2015. Stata Statistical Software: Release 14. College Station, TX: Stata Crop LP) was used to analyze the data.
