Moradhvaj, Samir KC. Differential impact of maternal education on under-five mortality in rural and urban India. Health Place 2023; 80:102987. [PMID: 36801652 DOI: 10.1016/j.healthplace.2023.102987] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2022] [Revised: 01/15/2023] [Accepted: 02/02/2023] [Indexed: 02/20/2023]
Abstract
Under-five mortality rate (U5MR) differs by rural-urban place of residence and mother's education; however, the rural-urban gap in U5MR by mother's educational attainment is unclear in the existing literature. Using five rounds of the national family health surveys (NFHS I-V) conducted between 1992-93 and 2019-21 in India, this study estimated the main and interaction effects of rural-urban and maternal education on U5MR. The mixed effect Cox proportional hazard (MECPH) model was used to predict the risk of under-five mortality (U5M). The finding shows that unadjusted U5MR remained 50 per cent higher in rural areas than in urban areas across the surveys. Whereas, after controlling for demographic, socioeconomic, and maternal health care predictors of U5M, the MECPH regression results indicated that urban children had a higher risk of death than their rural counterparts in NFHS I-III. However, there are no significant rural-urban differences in the last two surveys (NFHS IV -V). In addition, increasing maternal education levels were associated with lower U5M in all surveys. Though, in recent years, primary education has had no significant effect. The U5M risk was additionally lower for urban children than rural children whose mothers had secondary and higher education by NFHS-III; however, this additional urban advantage was no longer significant in recent surveys. The higher impact of secondary education on U5MR in urban areas in the past may be attributed to poor socio-economic, healthcare conditions in rural areas. Overall, maternal education, particularly secondary education, remained a protective factor for U5M in both rural and urban areas, even after controlling for predictors. Therefore, there is a need to increase the focus on secondary education for girls for a further decline in U5M.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18137091.

Abstract
Geographical inequalities in premature mortality and the role of neighbourhood social determinants of health (SDOH) have been less explored. This study aims to assess the geographical inequalities in premature mortality in Taiwan and how neighbourhood SDOH contribute to them and to examine the place-specific associations between neighbourhood SDOH and premature mortality. We used township-level nationwide data for the years 2015 to 2019, including age-standardized premature mortality rates and three upstream SDOH (ethnicity, education, and income). Space-time scan statistics were used to assess the geographical inequality in premature mortality. A geographical and temporal weighted regression was applied to assess spatial heterogeneity and how neighbourhood SDOH contribute to geographic variation in premature mortality. We found geographical inequality in premature mortality to be clearly clustered around mountainous rural and indigenous areas. The association between neighbourhood SDOH and premature mortality was shown to be area-specific. Ethnicity and education could explain nearly 84% variation in premature mortality. After adjusting for neighbourhood SDOH, only a handful of hotspots for premature mortality remained, mainly consisting of rural and indigenous areas in the central-south region of Taiwan. These findings provide empirical evidence for developing locally tailored public health programs for geographical priority areas.

Global Health 2019; 15:7. [PMID: 30670067 PMCID: PMC6341550 DOI: 10.1186/s12992-019-0450-5] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2018] [Accepted: 01/09/2019] [Indexed: 11/10/2022] Open
Abstract
Background Reducing premature deaths is an important step towards achieving the World Health Organization’s sustainable development goal. Redeployed miners are more prone to disease or premature death due to the special occupational characteristics. Our aims were to describe the deaths of redeployed miners, assess the losses due to premature death and identify their main health problems. All the records of individuals were obtained from Fuxin Mining Area Social Security Administration Center. Year of life lost (YLL) and average year of life lost were used to assess the loss due to premature death. YLL rates per 1000 individuals were considered to compare deaths from different populations. Results Circulatory system diseases contributed the most years of life lost in the causes of death, followed by neoplasms. But average year of life lost in neoplasms was 6.85, higher than circulatory system diseases, 5.63. Cerebrovascular disease and ischemic heart disease were the main causes of death in circulatory system diseases. And average years of life lost in cerebrovascular disease and ischemic heart disease were 5.85 and 5.62, higher than those in other circulatory system diseases. Lung cancer was the principal cause of death in neoplasms. Average year of life lost in liver cancer was 7.92, the highest in neoplasms. Conclusions For redeployed miners, YLL rates per 1000 individuals in cerebrovascular disease, ischemic heart disease and lung cancer were higher than those in other populations, especially in men. It is important to attach importance to the health of redeployed miners, take appropriate measures to reduce premature death and achieve the sustainable development goal. Our findings also contribute to a certain theoretical reference for other countries that face or will face the same problem.

Abstract
Chronic obstructive pulmonary disease (COPD) is one of the main contributors to the global burden of disease. The aim of this systematic review was to quantify the disease burden of COPD in China and to determine the risk factors of the disease. The number of studies included in the review was 47 with an average quality assessment score of 7.70 out of 10. Reported COPD prevalence varied between 1.20% and 8.87% in different provinces/cities across China. The prevalence rate of COPD was higher among men (7.76%) than women (4.07%). The disease was more prevalent in rural areas (7.62%) than in urban areas (6.09%). The diagnostic rate of COPD patients in China varied from 23.61% to 30.00%. The percentage of COPD patients receiving outpatient treatment was around 50%, while the admission rate ranged between 8.78% and 35.60%. Tobacco exposure and biomass fuel/solid fuel usage were documented as two important risk factors of COPD. COPD ranked among the top three leading causes of death in China. The direct medical cost of COPD ranged from 72 to 3,565 USD per capita per year, accounting for 33.33% to 118.09% of local average annual income. The most commonly used scales for the assessment of quality of life (QoL) included Saint George Respiratory Questionnaire, Airways Questionnaire 20, SF-36, and their revised versions. The status of QoL was worse among COPD patients than in non-COPD patients, and COPD patients were at higher risks of depression. The COPD burden in China was high in terms of economic burden and QoL. In view of the high smoking rate and considerable concerns related to air pollution and smog in China, countermeasures need to be taken to improve disease prevention and management to reduce disease burdens raised by COPD.

Abstract
The purpose of this study was to document the prevalence of Human Immunodeficiency Virus (HIV) and Hepatitis C Virus (HCV) among urban and rural methadone maintenance treatment (MMT) patients and to examine differences in knowledge of HIV and HCV among this population. We compared 147 MMT patients attending urban versus rural clinics in Kunming, Yunnan, China, concerning their serostatus and knowledge of HIV and HCV. The rates of HIV and HCV seropositive status were higher among rural patients. Both urban and rural patients showed limited HIV and HCV knowledge. Recent opioid injection and geographic area were strong predictors of HIV and HCV serostatus. The lack of knowledge of HIV and HCV among both urban and rural MMT patients suggests the need to strengthen current HIV and HCV education programs in MMT clinics. In addition, prevention programs should take into consideration geographic characteristics of the target population.

Abstract
BACKGROUND Injury is a growing public health concern in China. Injury death rates are often higher in rural areas than in urban areas in general. The objective of this study is to compare the injury mortality rates in urban and rural residents in Hubei Province in central China by age, sex and mechanism of injury. METHODS Using data from the Disease Surveillance Points (DSP) system maintained by the Hubei Province Centers for Disease Control and Prevention (CDC) from 2006 to 2008, injury deaths were classified according to the International Classification of Disease-10th Revision (ICD-10). Crude and age-adjusted annual mortality rates were calculated for rural and urban residents of Hubei Province. RESULTS The crude and age-adjusted injury death rates were significantly higher for rural residents than for urban residents (crude rate ratio 1.9, 95% confidence interval 1.8-2.0; adjusted rate ratio 2.4, 95% confidence interval 2.3-2.4). The age-adjusted injury death rate for males was 81.6/100,000 in rural areas compared with 37.0/100,000 in urban areas; for females, the respective rates were 57.9/100,000 and 22.4/100,000. Death rates for suicide (32.4 per 100,000 vs 3.9 per 100,000), traffic-related injuries (15.8 per 100,000 vs 9.5 per 100,000), drowning (6.9 per 100,000 vs 2.3 per 100,000) and crushing injuries (2.0 per 100,000 vs 0.7 per 100,000) were significantly higher in rural areas. Overall injury death rates were much higher in persons over 65 years, with significantly higher rates in rural residents compared with urban residents for suicide (279.8 per 100,000 vs 10.7 per 100,000), traffic-related injuries, and drownings in this age group. Death rates for falls, poisoning, and suffocation were similar in the two geographic groups. CONCLUSIONS Rates of suicide, traffic-related injury deaths and drownings are demonstrably higher in rural compared with urban locations and should be targeted for injury prevention activity. There is a need for injury prevention policies targeted at elderly residents, especially with regard to suicide prevention in rural areas in Central China.

Abstract
BACKGROUND Many sub-Saharan countries are confronted with persistently high levels of infant mortality because of the impact of a range of biological and social determinants. In particular, infant mortality has increased in sub-Saharan Africa in recent decades due to the HIV/AIDS epidemic. The geographic distribution of health problems and their relationship to potential risk factors can be invaluable for cost effective intervention planning. The objective of this paper is to determine and map the spatial nature of infant mortality in South Africa at a sub district level in order to inform policy intervention. In particular, the paper identifies and maps high risk clusters of infant mortality, as well as examines the impact of a range of determinants on infant mortality. A Bayesian approach is used to quantify the spatial risk of infant mortality, as well as significant associations (given spatial correlation between neighbouring areas) between infant mortality and a range of determinants. The most attributable determinants in each sub-district are calculated based on a combination of prevalence and model risk factor coefficient estimates. This integrated small area approach can be adapted and applied in other high burden settings to assist intervention planning and targeting. RESULTS Infant mortality remains high in South Africa with seemingly little reduction since previous estimates in the early 2000's. Results showed marked geographical differences in infant mortality risk between provinces as well as within provinces as well as significantly higher risk in specific sub-districts and provinces. A number of determinants were found to have a significant adverse influence on infant mortality at the sub-district level. Following multivariable adjustment increasing maternal mortality, antenatal HIV prevalence, previous sibling mortality and male infant gender remained significantly associated with increased infant mortality risk. Of these antenatal HIV sero-prevalence, previous sibling mortality and maternal mortality were found to be the most attributable respectively. CONCLUSIONS This study demonstrates the usefulness of advanced spatial analysis to both quantify excess infant mortality risk at the lowest administrative unit, as well as the use of Bayesian modelling to quantify determinant significance given spatial correlation. The "novel" integration of determinant prevalence at the sub-district and coefficient estimates to estimate attributable fractions further elucidates the "high impact" factors in particular areas and has considerable potential to be applied in other locations. The usefulness of the paper, therefore, not only suggests where to intervene geographically, but also what specific interventions policy makers should prioritize in order to reduce the infant mortality burden in specific administration areas.

Abstract
CONTEXT Urban-rural disparity is an important issue for injury control in China. Details of the urban-rural disparities in fatal injuries have not been analyzed. PURPOSE To target key injury causes that most contribute to the urban-rural disparity, we decomposed total urban-rural differences in 2006 injury mortality by gender, age, and cause. METHODS Mortality data came from the Chinese Vital Registration data, covering a sample of about 10% of the total population. The chi-square test was used to test the significance of urban-rural disparities. FINDINGS For all ages combined, the injury death rate for males was 60.1/100,000 in rural areas compared with 40.9 in urban areas; for females, the respective rates were 31.5 and 23.6/100,000. The greatest disparity was at age <1 year for both sexes, where the rate from unintentional suffocation in rural areas was more than twice the urban rate. The higher mortality from drowning among males of all ages and among females ages 1-24 and 35+ contributed substantially to the age-specific urban-rural disparities. For both sexes, transportation incidents and suicide were the most important contributors to higher rates among rural residents ages 15+. CONCLUSIONS Unintentional suffocation, drowning, transportation incidents, and suicide not only are the major causes of injury death, but also play a key role in explaining the urban-rural disparities in fatal injuries. Further research is needed to identify factors leading to higher rural death rates and to explore economical and feasible interventions for reducing injuries and narrowing the urban-rural gap in injury mortality.

Abstract
OBJECTIVES To investigate the burden of chronic diseases among rural-urban residents in Xuzhou, China. STUDY DESIGN Retrospective study. METHODS The mortality rates and standardized mortality rates of neoplasms, diabetes mellitus, ischaemic heart disease and cerebrovascular diseases were calculated for the 10 years from 1997 to 2006 in Xuzhou. The potential years of life lost, rate of life lost and standardized rate of life lost were calculated for each disease. Direct treatment costs were also analysed. RESULTS The age-standardized mortality rates of the four diseases were 150, 9, 78 and 96 per 100,000, respectively. The standardized rates of life lost among urban residents were 11.7, 0.8, 4.9 and 4.1 per thousand, respectively, and among rural residents were 15.0, 0.3, 2.9 and 2.8 per thousand, respectively. The total direct medical expenses, including outpatient and inpatient costs, was 6.07 hundred million Yuan. CONCLUSION Chronic diseases place a heavy burden on rural and urban residents in Xuzhou. A multidimensional and multidisciplinary health promotion and disease management plan is urgently needed to control these diseases.

Abstract
The rural-urban gap in infant mortality rates is explained by using a new decomposition method that permits identification of the contribution of unobserved heterogeneity at the household and the community level. Using Demographic and Health Survey data for six Francophone countries in Central and West sub-Saharan Africa, we find that differences in the distributions of factors that determine mortality--not differences in their effects--explain almost the entire gap. Higher infant mortality rates in rural areas mainly derive from the rural disadvantage in household characteristics, both observed and unobserved, which explain two-thirds of the gap. Among the observed characteristics, environmental factors--a safe source of drinking water, electricity, and quality of housing materials--are the most important contributors. Community characteristics explain less than one-quarter of the gap, with about two-thirds of this coming from community unobserved heterogeneity and one-third from the existence of a health facility within the community. The effect of disadvantageous environmental conditions--such as limited electricity and water supply--derives both from a lack of community-level infrastructure and from the inability of some households to exploit it when available. Policy needs to operate at both the community and household levels to correct such deficiencies.

Abstract
Background Years of Life Lost (YLL) is one of the methods used to estimate the duration of time lost due to premature death. While previous studies of disease burden have been reported using YLL, there have been no studies investigating YLL of Yi people in rural China. Yunnan Province ranks first in terms of Yi people in China. This paper uses YLL to estimate the disease burden of Yi people in Shilin county of Yunnan Province. This study aims to address the differentials about YLL between Yi people and Han people for providing useful information for health planning. Methods We applied the Global Burden of Disease (GBD) method created by WHO. YLL rate per 1,000 were calculated from medical death certificates in 2003 in Shilin Yi Nationality Autonomous County (Shilin county). Results The male had greater YLL rate per 1,000 than did the female almost in each age group. It demonstrated a higher premature mortality burden due to injuries in Shilin county. Among the top non-communicable diseases, respiratory diseases are the most common mortality burden. Yi people are still suffering from maternal conditions, with two times the burden rates of Han people. For Yi people, while malignant neoplasm was one of the least burden of disease for male, it was the greatest for female, which is the opposite to Han people. Conclusion Strategies of economic development should be reviewed to enhance the prevention and treatment of injuries, maternal conditions and respiratory diseases for Yi people.

Abstract
On average, child health outcomes are better in urban than in rural areas of developing countries. Understanding the nature and the causes of this rural-urban disparity is essential in contemplating the health consequences of the rapid urbanization taking place throughout the developing world and in targeting resources appropriately to raise population health. Using micro-data on child health taken from the most recent Demographic and Health Surveys for 47 developing countries, the purpose of this paper is threefold. First, we document the magnitude of rural-urban disparities in child nutritional status and under-5 mortality across all 47 developing countries. Second, we adjust these disparities for differences in population characteristics across urban and rural settings. Third, we examine rural-urban differences in the degree of socioeconomic inequality in these health outcomes. The results demonstrate that there are considerable rural-urban differences in mean child health outcomes in the entire developing world. The rural-urban gap in stunting does not entirely mirror the gap in under-5 mortality. The most striking difference between the two is in the Latin American and Caribbean region, where the gap in growth stunting is more than 1.5 times higher than that in mortality. On average, the rural-urban risk ratios of stunting and under-5 mortality fall by, respectively, 53% and 59% after controlling for household wealth. Controlling thereafter for socio-demographic factors reduces the risk ratios by another 22% and 25%. We confirm earlier findings of higher socioeconomic inequality in stunting in urban areas and demonstrate that this also holds for under-5 mortality. In a considerable number of countries, the urban poor actually have higher rates of stunting and mortality than their rural counterparts. The findings imply that there is a need for programs that target the urban poor, and that this is becoming more necessary as the size of the urban population grows.

Abstract
BACKGROUND We examined independent influences of contextual variables on cardiovascular risk factors in Shilin county, Yunnan province, South-west China. METHODS Three villages were selected from each of the ten townships based on probability proportional to size. In each selected village, 200 individuals aged > or = 45 years were chosen based on simple random sampling method. From 6006 individuals, information on demographic characteristics, smoking and drinking status was obtained by interview. Blood pressure, height, weight, and waist and hip girth were measured. Fasting blood sugar was measured in a 10-percent subsample. Contextual data were from official reports. Multi-level regression modelling with adjustment for individual and contextual variables was used. RESULTS Contextual variables associated with CVD risk factors included: remoteness of village with higher blood pressure and fasting blood sugar, high proportion of Yi minority with drinking, high literacy rate with a lower rate of smoking and a lower mean waist-hip ratio, and high average income with lower systolic blood pressure and body mass index (BMI) but higher FBS. CONCLUSION While contextual SES is associated with a few CVD risk factors, villages with high level of income are worse off in fasting blood sugar. Strategies of economic development should be reviewed to avoid adverse effects on health.
