As a result, mental health issues due to these phenomena are increasingly serious, making mental health both concerning public health and societal issues that have a great impact on economic and social development.~1 In 2014, there were16 million persons with severe mental disorders in China. The prevalence of all mental diseases reached 13.47%, ranking number one in the overall burden of disease and accounting for 20%of the overall burden of disease. By the year 2020, the ratio of mental illness to the overall burden of disease was projected to rise to 25%.~2 Unfortunately,展开更多

All of these areas are close to become conflict zones. However, no data about the Tubu's health and sanitary status are currently available, which would be of major concern if humanitarian interventions would become required.Methods: In 1970, the "Mission Anthropologique Belge au Niger"(MABN) investigated a Tubu tribe named Broaya that lived at Seguedine and Djado on the northeastern rim of the Tenere desert. One hundred fifty-one adult volunteers answered an oral questionnaire and underwent a medical examination, followed by the collection of blood thin films and samples of urine and stool. The environmental fauna of medical importance was also studied.Results: Albeit 43 year-old, these results have not been previously published. The estimated age of death for fathers was approximately 56 years, and that for mothers was 60 years. On average, each married woman had had 4.7 children. The overall perinatal mortality rate was 232 ‰, the overall infant mortality rate was 153 ‰, and the overall child mortality rate was 99 ‰. The mean height was 164.1 cm and 157.4 cm, the mean weight was 50.1 kg and 47.9kg, and the mean blood pressure was 131/78 mm Hg and 127/75 mm Hg for males and females, respectively. The physical examination found 6 cases of blindness(4.0%). Five subjects presented with an elevated blood pressure(3.3%), and 5(3.3%) displayed an abnormal thoracic auscultation evocative of tuberculosis or of an acute lung infection. The abdominal examination and renal palpation found 5 large masses(3.3%), and 2 subjects had a palpable enlarged spleen(1.3%). The blood thin films were fixed in methanol and subsequently examined in Toulouse. The search for blood parasites was negative. The urine samples were centrifuged and then microscopically examined in the field. No blood-fluke eggs were found. The stool samples were mixed with a preservative MIF solution and then stored to be examined later in Toulouse. Three subjects(2%) passed E. histolytica/E. dispar cysts in stools, 16(10.6%) were parasitized with Giardia sp. and 4(2.65%) were parasitized with Hymelepis nana. Two specimens of scorpions captured in the camp were subsequently identified as belonging to the harmful genus Androctonus or Leiurus. An investigation into the freshwater fauna was conducted in the marshy ponds surrounding the ghost city of Djado, and no intermediate snail hosts for schistosomiasis haematobium were found. Numerous nymphs of Ceratopogonidae, which are possible vectors for arboviruses of veterinarian importance, were collected, as were larvae and nymphs from two anopheline species, Anopheles hispaniola and An. multicolor, which are not efficient vectors for malaria.Conclusions: Infection-related blindness and trachoma, along with acute pulmonary infections and probably tuberculosis were the major health burden in this tribe. The harsh dry and hot climate may explain the low prevalence of soil-transmitted protozoan diseases or helminthiases.展开更多
