Evaluation of community based surveillance in the Rohingya refugee camps in Cox's Bazar, Bangladesh, 2019.

BACKGROUND: Following an influx of an estimated 742,000 Rohingya refugees in Bangladesh, Médecins sans Frontières (MSF) established an active indicator-based Community Based Surveillance (CBS) in 13 sub-camps in Cox's Bazar in August 2017. Its objective was to detect epidemic prone diseases early for rapid response. We describe the surveillance, alert and response in place from epidemiological week 20 (12 May 2019) until 44 (2 November 2019). METHODS: Suspected cases were identified through passive health facility surveillance and active indicator-based CBS. CBS-teams conducted active case finding for suspected cases of acute watery diarrhea (AWD), acute jaundice syndrome (AJS), acute flaccid paralysis (AFP), dengue, diphtheria, measles and meningitis. We evaluate the following surveillance system attributes: usefulness, Positive Predictive Value (PPV), timeliness, simplicity, flexibility, acceptability, representativeness and stability. RESULTS: Between epidemiological weeks 20 and 44, an average of 97,340 households were included in the CBS per surveillance cycle. Household coverage reached over 85%. Twenty-one RDT positive cholera cases and two clusters of AWD were identified by the CBS and health facility surveillance that triggered the response mechanism within 12 hours. The PPV of the CBS varied per disease between 41.7%-100%. The CBS required 354 full-time staff in 10 different roles. The CBS was sufficiently flexible to integrate dengue surveillance. The CBS was representative of the population in the catchment area due to its exhaustive character and high household coverage. All households consented to CBS participation, showing acceptability. DISCUSSION: The CBS allowed for timely response but was resource intensive. Disease trends identified by the health facility surveillance and suspected diseases trends identified by CBS were similar, which might indicate limited additional value of the CBS in a dense and stable setting such as Cox's Bazar. Instead, a passive community-event-based surveillance mechanism combined with health facility-based surveillance could be more appropriate.

Individual and community level factors associated with anemia among children 6-59 months of age in Ethiopia: A further analysis of 2016 Ethiopia demographic and health survey.

BACKGROUND: Anemia is a global public health problem; but its burden is disproportionately borne among children in the African Regions. The 2016 Ethiopia Demographic and Health Survey report showed that the prevalence of anemia among children 6-59 months of age was 57%; far exceeding the national target of 25% set for 2015. Although studies have been conducted in Ethiopia, multilevel analysis has rarely been used to identify factors associated with anemia among children. Therefore, this study aimed to identify individual and community-level factors associated with anemia among children 6-59 months of age by fitting a multilevel logistic regression model. METHODS: The data was obtained from the 2016 Ethiopia Demographic and Health Survey, conducted from January to June 2016, and downloaded from the website http://www.DHSprogram.com. The sample was taken using two-stage stratified sampling. In stage one, 645 Enumeration Areas and in stage two 28 households per Enumeration Area were selected. A sample of 7790 children 6-59 months of age was included. Data were analyzed using STATA version 14. A multilevel logistic regression model was fitted and an adjusted odds ratio with a 95% confidence interval was obtained. RESULT: From the individual-level factors, anemia was associated most strongly with child age, wealth index, maternal anemia and child stunting followed by child underweight, child fever and birth order whereas from the community-level, the strongest odds of anemia occurred among children from Somali, Harari, Dire Dawa and Afar region followed by Oromia and Addis Ababa. Low community-poverty is a protective factor for anemia. The odds of anemia were 0.81 (95% CI: 0.66, 0.99) times lower for children who were living in communities of lower poverty status than children who were living in communities of higher poverty status. Children from Somali and Dire Dawa had 3.38 (95% CI: 3.25, 5.07) and 2.22 (95% CI: 1.42, 3.48) times higher odds of anemia, respectively than children from the Tigray region. CONCLUSIONS: This study shows that anemia among children 6-59 months of age is affected both by the individual and community level factors. It is better to strengthen the strategies of early detection and management of stunted and underweight children. At the same time, interventions should be strengthened to address maternal anemia, child fever and poverty, specifically targeting regions identified to have a high risk of anemia.

Modern Contraceptive Utilization and Its Associated Factors among Indigenous and Nonindigenous Married Women of Reproductive Age Group in Jigjiga Town, Eastern Ethiopia, 2018.

BACKGROUND: The use of birth control and its promotion has potential benefits of reducing poverty, maternal, and child mortality. However, there is limited evidence regarding modern contraceptive utilization among indigenous and nonindigenous married women of the reproductive age group in Ethiopia. Therefore, this study aimed to assess the magnitude of modern contraceptive utilization and its associated factors among indigenous and nonindigenous married women in Eastern Ethiopia. Methodology. A community based comparative cross-sectional study design was conducted among married women of the reproductive age group from February 01 to March 01/2018 in Jigjiga town, Eastern Ethiopia. A total of 1004 married women were selected using a simple random sampling method. The collected data were entered into EpiData software version 3.1 and exported to SPSS version 22.0 for analysis. Bivariable and multivariable logistic regression analyses were used to identify the associated factors. Statistical significance was declared using 95% confidence interval and p value of less than 0.05. RESULT: A total of 987 study participants were included in the study with a response rate of 98.3%. The overall prevalence of modern contraceptive utilization among married reproductive age group women was found to be 19.9% (95% CI (17.4%-22.3%) with 26.5% and 11.4% for nonindigenous and indigenous women, respectively. Primary level of education (AOR 0.84; 95% CI (0.15-0.85) p 0.0001) and Somali in ethnicity (AOR 0.75; 95% CI (0.15-0.94) p 0.03) were associated factors among indigenous group, while age group 30-34 years (AOR 1.56; 95% CI (1.31-9.52) p 0.02) and being a housewife in occupation (AOR 0.49; 95% CI (0.42-0.96) p 0.04) were the associated factors among the nonindigenous group. CONCLUSION: Overall utilization of modern contraceptives was approximately one-fifth, with markedly lower use among indigenous participants. One-third of nonindigenous and less than one-seventh of indigenous were utilizing modern contraceptive methods. There is a need to further explore and understand the factors across indigenous and nonindigenous women for the use of modern contraceptives; hence, a longitudinal study is desirable.
