Bangladesh has been identified as one of the most vulnerable countries in the world concerning the adverse effects of climate change (CC). However, little is known about the perception of CC from the community, which is important for developing adaptation strategies.

Introduction Despite a realistic strategy and availability of resources, multiple challenges still overwhelm countries grappling with the challenges of communicable disease surveillance. The Integrated Disease Surveillance and Response (IDSR) strategy is by far the most pragmatic strategy in resource-poor settings. The objective of this study was to systematically review and document the lessons learned and the challenges identified with the implementation of the IDSR in low- and middle-income countries and to identify the main barriers that contribute to its sub-optimal functioning. Methods A systematic review of literature published in English using Web of Knowledge, PubMed, and databases of the World Health Organization (WHO) and the Centers for Disease Control (CDC) between 1998 and 2012 was undertaken. Additionally, manual reference and grey literature searches were conducted. Citations describing core and support functions or the quality attributes of the IDSR as described by WHO and CDC were included in the review. Results Thirty-three assessment studies met the inclusion criteria. IDSR strategy has been best adopted and implemented in the WHO–AFRO region. Although significant progress is made in overcoming the challenges identified with vertical disease surveillance strategies, gaps still exist. Mixed challenges with core and support IDSR functions were observed across countries. Main issues identified include non-sustainable financial resources, lack of co-ordination, inadequate training and turnover of peripheral staff, erratic feedback, inadequate supervision from the next level, weak laboratory capacities coupled with unavailability of job aids (case definitions/reporting formats), and poor availability of communication and transport systems particularly at the periphery. Best outcomes in core functions and system attributes were reported when support surveillance functions performed optimally. Apart from technical and technological issues, human resources and the health care system structures that receive the IDSR determine its output. Conclusions The challenges identified with IDSR implementation are largely ‘systemic’. IDSR will best benefit from skill-based training of personnel and strengthening of the support surveillance functions alongside health care infrastructures at the district level.

Chronic malnutrition is one of the major causes of morbidity and mortality among preschool children and the future productivity of nations. To understand the prevalence of chronic malnutrition and to identify the factors affecting height-for-age z-score (HAZ) among preschool children, a cross-sectional study was conducted among 380 randomly-selected children aged less than five years in Dhaka city, Bangladesh. Results of analysis of this study data revealed that the prevalence of stunting among preschool children in Dhaka city was 39.5%, with 25% severely stunted and 14% moderately stunted (p<0.001). Results of bivariate analysis revealed that socioeconomic and demographic factors were most significantly associated with the stunting of children. Children were found to be well-nourished if their parents had a tertiary-level education or higher and if the mother held a job and had good knowledge of nutrition. Well-nourishment of the children were also associated with the height of mothers (above 148 cm), good family educational background, normal birthweight, greater frequency of food intake (more than six times/day), and fewer fever episodes in the last six months. Results of multivariate linear regression models showed that height of mothers, birthweight of children, education of fathers, knowledge of mothers on nutrition, and frequency of feeding were the most significant factors that had an independent and direct influence on the stunting of children. To achieve the Millennium Development Goal target of 34% malnutrition prevalence by 2015, it is important to have specific government intervention to focus on the causes that directly influence the stunting of children.
