“…A negative correlation of GDP per capita and child dysentery was observed, which means that the lack of economic production is associated with the health of children at the country level. This finding is consistent with other epidemiological studies, which present how the lack of economic resources at the country level is associated with the decrease and absence of opportunities and in turn with impaired health of the population [27,28].…”

42 Objective: Dysentery represents 10% of all causes of acute diarrhea in the world 43 and recognizing the implied proximal and distal social factors at different levels would 44 impact on every related outcome. Our purpose is to identify mother, household and 45 country characteristics that favor the presence of dysentery in children under 5 years 46 old. Methods: We conducted a multilevel analysis of data from phase V of the 47 Demographic and Health Survey and the World Bank, which included 38,762 48 children from 33 countries. Results: Prevalence of dysentery was 14.74%. GDP per-49 capita was negative associated (OR= 0.75; 95% CI 0.71-0.78) and Gini index was 50 positive associated (OR= 1.23; 95% CI 1.19-1.28). Additionally, child age (OR= 51 0.99; 95% CI 0.99-1.00), mother age (OR= 1.01; 95% CI 1.00-1.01), employed 52 mother (OR= 1.11; 95% CI 1.02-1.20), and number of household members (OR= 53 1.02; 95% CI 1.01-1.03) have significant positive associations with the presence of 54 dysentery, while complete immunization schedule (OR= 0.88; 95% CI 0.81-0.96), 55 duration of breastfeeding (OR= 0.81; 95% CI 0.75-0.89), and type of residence (OR= 56 0.87; 95% CI 0.79-0.97) have significant negative associations with having the 57 illness. Finally, each of the categories of wealth index showed a significant 58 association with dysentery (p-value < 0.001). Conclusions: Lower per capita GDP 59 and higher Gini coefficient are associated with the development of dysentery, 60 regardless of characteristics of children, their mother, and household. Future and 3 61 present public health programs should address these issues in order to impact on 62 the occurrence of this illness. 63 64 Author summary 65 Dysentery represents 10% of all causes of acute diarrheal disease. Diarrhea 66 is the fifth cause of worldwide death in children under five years old. It is particularly 67 important to assess and prevent this condition because the early years of life are68 critical since it is the period when the brain develops most rapidly and has a high 69 capacity for change. Complications associated with dysentery such as malnutrition 70 and convulsive episodes could have a negative effect in this aspect. 71Our purpose is to identify the country proximal and distal socioeconomic 72 factors that favor the presence of dysentery in children under five years old from low 73 and middle-income developing countries in order to impact on the occurrence of this 74 illness and its related outcomes. Studying associated factors with developing 75 dysentery during an episode of acute diarrhea could be the base upon which we can 76 diminish mortality from this illness through national policies to impact on national, 77 community and household aspects. 78 79 80 81 82 83 4 84 85 Acute diarrheal disease (ADD) is defined as the presence of three or more 86 abnormally loose or watery stools in 24 hours. It is the second cause of death in 87 children under five years old [1,2], with a worldwide prevalence of about 8% [3]. This 88 illness is caused usually b...

“…This study found that 68,855 BD cases were reported in Chongqing from 2009 to 2016, with an average annual incidence of 29.394/100,000. Although BD incidence in Chongqing showed a downward trend overall, it was still higher than the incidence in the same period in China (20.28/100,000 in 2009, 15.29/100,000 in 2012, 11.24/ 100,000 in 2014) [21,22], the USA in 2016 (6.53/100, 000), Zhejiang Province between 2004 and 2015 (4.25/ 100,000) and Sichuan Province between 2004 and 2014 (22.12/100,000) [1,5,23], which highlights the serious situation regarding the prevention and control of BD in Chongqing. Chongqing has a subtropical monsoon humid climate and covers an area of 824,000 km 2 , of which 78% is mountainous; it has sufficient precipitation, a warm temperature and a suitable climate for the growth and reproduction of Shigella, which may be one of the reasons BD incidence in Chongqing is higher than that in other areas.…”

“…BD incidence was higher in men than in women in Chongqing, and the proportion of farmers was relatively large; this finding is consistent with other research results and may be attributed to that men are more likely to lack good health habits and to participate in group activities such as attending parties and dining out. Additionally, while the physical activity level of farmers is high, their working environments are frequently unsanitary [1,5,8,21,27]. This, coupled with a lack of knowledge of disease prevention and control, results in elevated incidences of BD among men and farmers.…”

“…However, the risk of infectious diseases has always been affected by multiple factors, such as climate, the regional economy and environmental health. The impacts of meteorological factors on diseases, especially infectious diseases, are of particular current concern to researchers, and relevant studies have been comprehensive [5][6][7][8][9][10]. Numerous studies have concluded that BD transmission might be influenced by meteorological factors [11][12][13][14].…”

Background: This study aimed to analyse the epidemiological characteristics of bacillary dysentery (BD) caused by Shigella in Chongqing, China, and to establish incidence prediction models based on the correlation between meteorological factors and BD, thus providing a scientific basis for the prevention and control of BD.Methods: In this study, descriptive methods were employed to investigate the epidemiological distribution of BD. The Boruta algorithm was used to estimate the correlation between meteorological factors and BD incidence. The genetic algorithm (GA) combined with support vector regression (SVR) was used to establish the prediction models for BD incidence. Results: In total, 68,855 cases of BD were included. The incidence declined from 36.312/100,000 to 23.613/100,000, with an obvious seasonal peak from May to October. Males were more predisposed to the infection than females (the ratio was 1.118:1). Children < 5 years old comprised the highest incidence (295.892/100,000) among all age categories, and pre-education children comprised the highest proportion (34,658 cases, 50.335%) among all occupational categories. Eight important meteorological factors, including the highest temperature, average temperature, average air pressure, precipitation and sunshine, were correlated with the monthly incidence of BD. The obtained mean absolute percent error (MAPE), mean squared error (MSE) and squared correlation coefficient (R 2 ) of GA_SVR_MONTH values were 0.087, 0.101 and 0.922, respectively.Conclusion: From 2009 to 2016, BD incidence in Chongqing was still high, especially in the main urban areas and among the male and pre-education children populations. Eight meteorological factors, including temperature, air pressure, precipitation and sunshine, were the most important correlative feature sets of BD incidence. Moreover, BD incidence prediction models based on meteorological factors had better prediction accuracies. The findings in this study could provide a panorama of BD in Chongqing and offer a useful approach for predicting the incidence of infectious disease. Furthermore, this information could be used to improve current interventions and public health planning.

For areas facing challenges associated with migration, information about the number of migrants and their demographic characteristics is needed to formulate regional development planning. This study analyzed the trends and characteristics of inter-provincial migrants in provinces in mainland China and related economic factors using panel regression models. The results showed that the number of inter-provincial migrants had increased in provincial municipalities, as had the proportions of female and elderly migrants. A higher annual net migration rate was associated with slower growth rate of real gross domestic product (RGDP) per capita and faster growth rates of the tertiary and secondary industry GDPs. The higher proportion of female migrants was related to the faster growth rate of the tertiary industry GDP and the lower proportion of the secondary industry in GDP. The proportion of youth migrants was positively related to educational investment, while the proportion of elderly migrants was positively related to financial expenditure per capita on culture and recreation. These empirical results were robust across different estimation methods, except the result about the proportion of elderly migrants. These findings further reveal the association between inter-provincial migration and economy and provide policy reference for the management of migrants.
