Are first-trimester pregnant women consuming adequate and diverse diet? A hospital-based cross-sectional study in Karachi, Pakistan

Abstract

Abstract Background Maintaining a healthy and diverse diet during pregnancy is crucial for maternal well-being and fetal development. The first trimester marks the beginning of vital developmental processes influenced by maternal nutritional status. Therefore, we aimed to determine dietary adequacy and diversity among first-trimester pregnant women. Methods In this cross-sectional study, we recruited 306 first-trimester pregnant women from the antenatal clinics of Aga Khan University Hospital, Karachi (January 2020 to September 2021). Eligible women possessed smartphones (for the mHealth intervention trial) and reported no major comorbidities or medication use. Data about socio-demographic, obstetric, and dietary history were collected through interviews using a structured questionnaire. Booking weight, height, blood pressure, and haemoglobin levels were extracted from medical records. An aggregate dietary risk score (DRS) was calculated separately for quantity and quality by summing the DRS for each of the six major food groups. A score of 0 was assigned to adequate, 1.5 to intermediate, and 3 to inadequate quantity or quality categories. Data were analysed using STATA 14.0. Results The mean ± SD for DRS quantity and quality were 10.6 ± 2.4 and 7.5 ± 2.5, respectively. Adequate dietary quantity and quality per week for starch-based food were reported by 14.4% and 21.2%, for vegetables by 0.3% and 49%, for fruits by 41.2% and 88.6%, for animal and plant protein by 19% and 0%, for milk and milk products by 1% and 37.6% and for oils and fats by 90.5% and 8.8%, respectively. Sweet and savoury snacks were eaten by 74.8% and 53.9%, respectively. Ready-made meals, carbonated beverages, packaged juices, and additional salt were consumed by 55.2%, 46.4%, 34.3%, and 7.5%, respectively. The median (IQR) water intake was 6 (4–8) glasses/day. Conclusions During the early stages of pregnancy, women enrolled for antenatal care at an urban private tertiary care hospital report inadequate dietary intake for various food groups, except for the quantity of oils/fats and the quality of fruit consumption. Poor dietary practices underscore the need for focused and impactful dietary counselling during the initial stages of pregnancy.
