Accuracy of Mid-Upper Arm Circumference for Detecting Acute Malnutrition in Children Aged 6-59 Months in an Urban Slum in Bangladesh: A Cross-Sectional Analysis.

Background The weight-for-height z-score (WHZ) is considered the gold standard for detecting acute malnutrition in children. However, an accurate assessment of WHZ can often be challenging, especially in community settings. Mid-upper arm circumference (MUAC) is a simple and easy-to-perform method to identify children with acute malnutrition. The objective of the study was to evaluate the accuracy of MUAC in detecting acute malnutrition compared to WHZ among children aged 6-59 months in Bangladesh. Methods We used anthropometric data for 239 children aged 6-59 months from a cross-sectional study conducted in 2013 in an urban slum in Dhaka, Bangladesh. The sensitivity and specificity of MUAC to detect acute malnutrition were calculated, considering WHZ as the gold standard. Results The mean age of the children was 29.4 ± 12.7 months, with a male-to-female ratio of 1:1.2. The prevalence of acute malnutrition was 17.1% and 22.5% based on WHZ and MUAC, respectively. The total area under the receiver operating characteristic curve was 0.816. For detecting acute malnutrition, the sensitivity of MUAC was 61.0% and the specificity was 85.4% for the World Health Organization (WHO) recommended cutoff of <125 mm. Using the Youden index, the best MUAC cutoff point to detect acute malnutrition was <128 mm with a sensitivity of 75.6% and a specificity of 74.7%. Conclusions Our study demonstrated a low sensitivity of MUAC to identify acute malnutrition at the WHO cutoff of <125 mm. The cutoff could be increased to <128 mm to capture more children with acute malnutrition.

Parenchymal asbestosis due to primary asbestos exposure among ship-breaking workers: report of the first cases from Bangladesh.

We report for the first time asbestosis among ship-breaking workers of Sitakunda in Bangladesh who were exposed to asbestos during ship-based and beach-based operations for at least 10 years. Asbestosis was present among 35% of workers. Years of work (>20) and forced vital capacity (<80% of predicted) were significantly associated with the disease. Currently, global ship-breaking operations are mainly concentrated in the Indian subcontinent, and Bangladesh has the majority share. Ninety per cent of domestic steel is produced in the ship-breaking operations in Bangladesh and is an important contributor to the economy. It also gives employment to more than 100 000 people. It is imperative to medically check up all the workers for benign and malignant diseases causally related to asbestos among these vulnerable population of workers.

Basic occupational health services (BOHS) in community primary care: the MSF (Dhaka) model.

The Médecins Sans Frontiérs (MSF) established basic occupational health services to diagnose and treat work-related diseases among tannery, metal, plastics and garment workers and families in one of the more polluted areas of the world populated by 600 000 people. In spite of project limitations, an analysis of the 6-month data showed that of the original cohort of 5000, 3200 (64%) came for at least 1 consultation. Among them, 468 (14.6%) were diagnosed with suspected work-related diseases as per defined protocols. Follow-up consultation was performed for 1447 cases of occupational diseases and work-related injuries. The MSF experience begs the need for replication of such services in densely populated urban areas in developing nations like Bangladesh and India, where no specialty occupational health clinics exist in primary care but are desperately needed and where occupational health clinics on factory premises are exclusive to industry workers and are not accessible to communities.
