Objective: The present study determined trends in malnutrition among under-5 children in urban and rural areas of Bangladesh. Design: Surveillance. Setting: The study was conducted in the urban Dhaka and the rural Matlab hospitals of the International Centre for Diarrhoeal Disease Research, Bangladesh, where every fiftieth patient and all patients coming from the Health and Demographic Surveillance System were enrolled. Subjects: A total of 28 816 under-5 children were enrolled at Dhaka from 1993 to 2012 and 11 533 at Matlab between 2000 and 2012. Results: In Dhaka, 46 % of the children were underweight, 39 % were stunted and 28 % were wasted. In Matlab, the corresponding figures were 39 %, 31 % and 26 %, respectively. At Dhaka, 0·5 % of the children were overweight and obese when assessed by weight-for-age Z-score >+2·00, 1·4 % by BMI-for-age Z-score >+2·00 and 1·4 % by weight-for-height Z-score >+2·00; in Matlab the corresponding figures were 0·5 %, 1·4 % and 1·4 %, respectively. In Dhaka, the proportion of underweight, stunting and wasting decreased from 59 % to 28 % (a 53 % reduction), from 54 % to 22 % (59 % reduction) and from 33 % to 21 % (36 % reduction), respectively, between 1993 and 2012. In Matlab, these indicators decreased from 51 % to 27 % (a 47 % reduction), from 36 % to 25 % (31 % reduction) and from 34 % to 14 % (59 % reduction), respectively, from 2000 to 2012. On the other hand, the proportion of overweight (as assessed by BMIfor-age Z-score) increased significantly over the study period in both Dhaka (from 0·6 % to 2·6 %) and Matlab (from 0·8 % to 2·2 %). Conclusions: The proportion of malnourished under-5 children has decreased gradually in both urban and rural Bangladesh; however, the reduction rates are not in line with meeting Millennium Development Goal 1. Trends for increasing childhood obesity have been noted during the study period as well.

Bangladesh Malnutrition Overweight and obesityRural and urban Under-5 childrenEconomic improvement and reduction in poverty, both in developed and developing countries, have been observed within the last couple of decades; however, the pace is not sufficient to meet Millennium Development Goal 1 ('eradicate extreme poverty and hunger') (1) . Improvement has also occurred in meeting basic health needs such as the prevention and treatment of infectious and communicable diseases (2) , and efforts have been made to ensure provision of safe drinking-water and improved sanitation practices to reduce diarrhoeal episodes (2,3) . According to WHO, globally about 27 % of children are stunted (4) and 17 % are underweight (5) . The scenario is even worse in the Asian subcontinent and sub-Saharan Africa (2) . Despite efforts to reduce childhood malnutrition through various interventions, it remains a great public health challenge (2) . The other components of malnutrition, such as overweight and obesity, are emerging public health concerns (6,7) . In 2011, WHO reported that over 40 million children under the age of 5 years (under-5s) were ove...
