In Pakistan, 51% of women are anaemic in pregnancy yet only 44% of women use antenatal iron-folic acid (IFA) supplements. Little information exits on the perception and barriers to the use of IFA supplements during pregnancy in Pakistan. The aim of the study was to understand women and healthcare providers’ perceptions, and to investigate the cultural and behavioural factors influencing the use of antenatal IFA supplements in rural and urban settings of Pakistan. We conducted 10 focus group discussions with mothers, 10 in-depth interviews with currently pregnant women, 6 in-depth interviews with Lady Health Workers and 4 in-depth interviews with doctors providing antenatal care services. The study was conducted in two districts of Pakistan - district Swabi and Islamabad for rural and urban samples, respectively. Data was collected between August and November 2012. The majority of women were aware of the perceived benefits of antenatal IFA supplements. However, the rural women had more limited information about the benefits of IFA supplements than the urban women. The facilitating factors for the women’s use of supplements were: they had knowledge of benefits; they had trust in the healthcare providers; the supplements were available; they had the financial capacity to buy them; they felt better after taking these supplements; and they received support from family members. The barriers to the women’s use of supplements were: they forgot to take them; the non-availability of supplements; their limited financial capacity to buy them; the lack of antenatal care services; family members not allowing use of the supplements; not knowing about the benefits or no education; fear or experience of side effects; considering them as contraceptives; and felt better thus stopped. The coverage of antenatal IFA supplementation can be improved by reducing the barriers related to the use of antenatal IFA supplementation in Pakistan. Interventions focused on providing adequate awareness, good quality counselling, reminder messages, availability of free supplements throughout pregnancy and reducing the side effects should be developed and implemented.

The aim of the study was to investigate the effect of antenatal iron-folic acid (IFA) supplementation on child stunting in Nepalese children age <2 years. A retrospective cohort study design was used, in which a pooled cohort of 5235 most recent live births 2 years prior to interview from three Nepal Demographic and Health Surveys (2001, 2006 and 2011) was analysed. The primary outcome was stunting in children age <2 years. The main exposure variable was antenatal IFA supplementation. Multivariate Poisson regression analysis was performed. In our sample, 31% and 10% of Nepalese children age <2 years were stunted and severely stunted, respectively. The adjusted relative risk of being stunted was 14% lower in children whose mothers used IFA supplements compared to those whose mothers did not use (aRR = 0.86, 95% CI = 0.77–0.97). Additionally, the adjusted relative risk of being stunted was significantly reduced by 23% when antenatal IFA supplementation was started ≤6 months with ≥90 IFA supplements used during pregnancy (aRR = 0.77, 95% CI = 0.64–0.92). Antenatal IFA supplementation significantly reduced the risk of stunting in Nepalese children age <2 years. The greatest impact on the risk reduction of child stunting was when IFA supplements were started ≤6 months with ≥90 supplements were used.

World Health Organisation recommends that pregnant women with no complications should visit a healthcare provider at least four times to receive sufficient antenatal care services. In Pakistan only 37 % of women reported to have had four or more antenatal care visits during their last pregnancy. This study aimed to explore facilitators and barriers to use of antenatal care services in rural and urban communities of two selected districts in Pakistan. Qualitative explorative study using in-depth interviews with currently pregnant women, lady health workers and doctors providing antenatal care services, and focus group discussion with women who had a child aged 5 years or younger, was conducted in a rural community in the district Swabi and in a tertiary care hospital in urban Islamabad in Pakistan. The audio-recorded interviews and discussions were transcribed verbatim in Urdu (the language spoken by the respondents). A list of topical codes for all topics related to the research questions was developed. Subsequently the text pertaining to each topical code was discussed and summarised in a document that presented the findings for each topic using quotes and tables. We conducted in-depth interviews with six lady health workers, four doctors, and ten currently pregnant women, and facilitated ten focus group discussions with women who had a child aged 5 years or younger. Currently pregnant women, and women who had a child aged 5 years or younger, were not aware of the recommended minimum number of antenatal care visits to be made during pregnancy. Facilitating factors to visit a particular health care facility were: availability of qualified healthcare providers (private facility); trust in healthcare providers; recommendation from a family member, friend or lady health worker (in rural areas); availability of good quality services including medical equipment and laboratory facilities; low cost (public facility); and easy access to the health facility (private facility). Common barriers to visiting a health facility for antenatal care services were: financial limitations; perceived absence of any major health problems during pregnancy; difficulties in reaching the health facility; restriction from husband or mother-in-law; busy performing household chores; no previous experience of antenatal care visits; and perceived unavailability of healthcare providers and/or services. The current study identified several policy-relevant facilitating factors and barriers to visiting a health facility for antenatal care services as reported by urban and rural women, and healthcare providers. There is a need to formulate and implement intervention packages based on these findings to increase the coverage of the recommended four antenatal care visits in Pakistan.

In South Asia, an estimated 38% of preschool-age children have stunted growth. We aimed to assess the effect of WHO-recommended antenatal iron, and folic acid (IFA) supplements on smaller than average birth size and stunting in South Asian children <2 years old. The sample was 96,512 mothers with their most recent birth within two years, from nationally representative surveys between 2005 and 2016 in seven South Asian countries. Primary outcomes were stunting [length-for-age Z-score (LAZ) < –2], severe stunting [length-for-age Z-score (LAZ) < –3], length-for-age Z score, and perceived smaller than average birth size. Exposure was the use of IFA supplements. We conducted analyses with Poisson, linear and logistic multivariate regression adjusted for the cluster survey design, and 14 potential confounders covering the country of the survey, socio-demographic factors, household economic status, maternal characteristics, and duration of respondent recall. The prevalence of stunting was 33%, severe stunting was 14%, and perceived smaller than average birth size was 22%. Use of antenatal IFA was associated with a reduced adjusted risk of being stunted by 8% (aRR 0.92, 95% CI 0.89, 0.95), of being severely stunted by 9% (aRR 0.91, 95% CI 0.86, 0.96) and of being smaller than average birth size by 14% (aRR 0.86, 95% CI 0.80, 0.91). The adjusted mean LAZ was significantly higher in children whose mothers used IFA supplements. Maternal use of IFA in the first four months gestation and consuming 120 or more supplements throughout pregnancy was associated with the largest reduction in risk of child stunting. Antenatal IFA supplementation was associated with a significantly reduced risk of stunting, severe stunting, and smaller than average perceived birth size and improved LAZ in young South Asian children. The early and sustained use of antenatal IFA has the potential to improve child growth outcomes in South Asia and other low-and-middle-income countries with high levels of iron deficiency in pregnancy.

Introduction Healthcare providers in resource-limited settings rely on the presence of tachypnoea and chest indrawing to establish a diagnosis of pneumonia in children. We aimed to determine the test characteristics of commonly assessed signs and symptoms for the radiographic diagnosis of pneumonia in children 0–59 months of age. Methods We conducted an analysis using patient-level pooled data from 41 shared datasets of paediatric pneumonia. We included hospital-based studies in which >80% of children had chest radiography performed. Primary endpoint pneumonia (presence of dense opacity occupying a portion or entire lobe of the lung or presence of pleural effusion on chest radiograph) was used as the reference criterion radiographic standard. We assessed the sensitivity, specificity, and likelihood ratios for clinical findings, and combinations of findings, for the diagnosis of primary endpoint pneumonia among children 0–59 months of age. Results Ten studies met inclusion criteria comprising 15 029 children; 24.9% (n=3743) had radiographic pneumonia. The presence of age-based tachypnoea demonstrated a sensitivity of 0.92 and a specificity of 0.22 while lower chest indrawing revealed a sensitivity of 0.74 and specificity of 0.15 for the diagnosis of radiographic pneumonia. The sensitivity and specificity for oxygen saturation <90% was 0.40 and 0.67, respectively, and was 0.17 and 0.88 for oxygen saturation <85%. Specificity was improved when individual clinical factors such as tachypnoea, fever and hypoxaemia were combined, however, the sensitivity was lower. Conclusions No single sign or symptom was strongly associated with radiographic primary end point pneumonia in children. Performance characteristics were improved by combining individual signs and symptoms.

As one of the leading causes of child mortality, diarrhoeal diseases pose a significant global burden, disproportionately affecting children in low- and middle-income countries (LMICs) [1]. In 2017, diarrhoeal diseases were responsible for approximately 8% of worldwide deaths among post-neonatal children aged 1 to 59 months, with 525 000 children dying yearly [1]. Managing childhood diarrhoea […]
