During the last decade, conflict or natural disasters have displaced unprecedented numbers of persons. This leads to conditions prone to outbreaks that imperil the health of displaced persons and threaten global health security. Past literature has minimally examined the association of communicable disease outbreaks with complex emergencies (CEs) and natural disasters (NDs). To examine this association, we identified CEs and NDs using publicly available datasets from the Center for Research on the Epidemiology of Disasters and United Nations Flash and Consolidated Appeals archive for 2005–2014. We identified outbreaks from World Health Organization archives. We compared findings to identify overlap of outbreaks, including their types (whether or not of a vaccine-preventable disease), and emergency event types (CE, ND, or Both) by country and year using descriptive statistics and measure of association. There were 167 CEs, 912 NDs, 118 events linked to ‘Both’ types of emergencies, and 384 outbreaks. Of CEs, 43% were associated with an outbreak; 24% NDs were associated with an outbreak; and 36% of ‘Both’ types of emergencies were associated with an outbreak. Africa was disproportionately affected, where 67% of total CEs, 67% of ‘Both’ events (CE and ND), and 46% of all outbreaks occurred for the study period. The odds ratio of a vaccine-preventable outbreak occurring in a CE versus an ND was 4.14 (95% confidence limits 1.9, 9.4). CEs had greater odds of being associated with outbreaks compared with NDs. Moreover, CEs had high odds of a vaccine-preventable disease causing that outbreak. Focusing on better vaccine coverage could reduce CE-associated morbidity and mortality by preventing outbreaks from spreading.

The prevalence of unplanned pregnancy in Saudi Arabia has not been thoroughly investigated. To conduct a psychometric evaluation study of the Arabic version of the London Measure of Unplanned Pregnancy (LMUP). To evaluate the psychometric properties of the LMUP, we conducted a self-administered online survey among 796 ever-married Saudi women aged 20–49 years, and a re-test survey among 24 women. The psychometric properties evaluated included content validity measured by content validity index (CVI), structural validity assessed by exploratory factor analysis (EFA), substantive validity assessed by hypothesis testing, contextual stability for the test-retest assessed by weighted Kappa, and internal consistency assessed by Cronbach’s alpha. The psychometric analysis of the Arabic version of LMUP exhibited valid and reliable properties. The CVIs for individual items and at the scale level were >0.7. EFA confirmed a unidimensional extraction of the scale item. Hypothesis testing confirmed expected associations. The tool was stable with weighted kappa = 0.78 and Cronbach’s alpha = 0.88. In this study, the validity and reliability of the Arabic version of the LMUP were confirmed according to well-known psychometric criteria. This LMUP version can be used in research studies among Arabic-speaking women to measure unplanned pregnancy and investigate correlates and outcomes related to unplanned pregnancy.

In this article, the authors focus on epidemic-assistance investigations that dealt with maternal and child health problems, including unintended and adolescent pregnancy and family planning; international reproductive health surveys among refugees; pregnancy outcomes, including abortion, maternal mortality, infant mortality, and birth defects; leukemia; and Reye syndrome. During 1946–2005, a total of 1,969 investigations had sufficient data to classify them as possibly related to maternal and child health and were characterized by distinctive periods. Those related to family planning, pregnancy intention, and reproductive health among refugees began in the early 1970s and continued through 2005. Abortion-related investigations occurred during 1971–1982. Investigations of non-abortion-related maternal morbidity and mortality began in 1979 and included 2 international epidemic-assistance investigations. Investigations of clusters of disease among infants began in the 1960s, with a special focus on Reye syndrome during 1964–1984. Investigations of childhood cancer and birth defects began in the late 1950s. The Centers for Disease Control and Prevention has used the epidemic-assistance investigations mechanism to respond to a wide range of health concerns of women and children. The investigations of abortion-related health problems might have had the best-documented impact on public policy and public health.
