874 flat scale

Eligible women were consented and enrolled at the beginning of the study visit, which occurred in the morning or early afternoon depending on the woman's availability. Data collection for enrolled women consisted of questions that were administered orally by trained study staff, and responses were recorded on a Samsung Galaxy Tab 4 (Model SM-T230NU; Samsung Electronics) using Open Data Kit 2.0 software (23 ). We adopted a questionnaire that has been used to assess household socioeconomic status and food insecurity in the study area (24 (link)). We added questions on pregnancy and health history and slightly adapted some questions related to socioeconomic status based on the interests of the current study.
Height was measured to the nearest 0.1 cm using the Seca 217 stadiometer (Seca GmbH), and weight was measured to the nearest 0.1 kg using the Seca 874 flat scale (Seca GmbH). Participants wore minimal or light clothing; they were also asked to remove shoes and any heavy clothing or objects, such as jewelry, before weighing. Each measurement was repeated twice, and the mean was calculated. Women provided a small urine sample, and a URIT 2 V reagent strip (URIT Medical Electronic Group) was read 30 s after dipping in the urine. By color, it indicated a range of 4 categories of protein: negative/trace, 30 mg/dL, 100 mg/dL, and ≥300 mg/dL.
