RESUMEN
Desert dust and sandstorms are recurring environmental phenomena that are reported to produce serious health risks worldwide. This scoping review was conducted to identify the most likely health effects of desert dust and sandstorms and the methods used to characterize desert dust exposure from the existing epidemiological literature. We systematically searched PubMed/MEDLINE, Web of Science, and Scopus to identify studies that reported the effects of desert dust and sandstorms on human health. Search terms referred to desert dust or sandstorm exposure, names of major deserts, and health outcomes. Health effects were cross-tabulated with study design variables (e.g., epidemiological design and methods to quantify dust exposure), desert dust source, health outcomes and conditions. We identified 204 studies that met the inclusion criteria for the scoping review. More than half of the studies (52.9%) used a time-series study design. However, we found a substantial variation in the methods used to identify and quantify desert dust exposure. The binary metric of dust exposure was more frequently used than the continuous metric for all desert dust source locations. Most studies (84.8%) reported significant associations between desert dust and adverse health effects, mainly for respiratory and cardiovascular mortality and morbidity causes. Although there is a large body of evidence on the health effects of desert dust and sandstorms, the existing epidemiological studies have significant limitations related to exposure measurement and statistical analysis that potentially contribute to inconsistencies in determining the effect of desert dust on human health.
RESUMEN
Female entertainment workers (FEWs) are at higher risk of gender-based violence (GBV) than the general population. The prolonged stress and fear caused by GBV increase the likelihood of depression, a major mental health problem among FEWs. However, their mental health issue has received limited attention and remains poorly researched in the context of GBV. We examined the association between GBV and depressive symptoms among FEWs in Cambodia. We conducted this cross-sectional study in 2017. We used a two-stage cluster random sampling method to select FEWs from the municipality and six provinces for face-to-face interviews. We used the Centre for Epidemiologic Studies Depression Scale (CES-D) to measure depressive symptoms. We conducted a multivariable logistic regression analysis to identify factors associated with depressive symptoms. We included a total of 645 FEWs in data analyses. The proportions of FEWs experiencing emotional, physical, and sexual violence were 36.1%, 11.6%, and 17.2%, respectively. Of the total participants, 65.9% had high levels of depressive symptoms. The adjusted odds of having high levels of depressive symptoms were higher among FEWs who engaged in transactional sex (AOR 1.79, 95% CI 1.09-2.94), experienced emotional abuse (AOR 3.15, 95% CI 1.90-5.23), and experienced two (AOR 7.89, 95% CI 3.28-18.99) and three overlapping types of GBV (AOR 12.12, 95% CI 2.47-59.25) than those who did not. FEWs in this study experienced high levels and overlapping types of GBV associated with high levels of depressive symptoms. Policy interventions and services should be designed to prevent GBV and support the victims of GBV to mitigate depressive symptoms among FEWs in Cambodia.
