Indigenous and tribal peoples' health (The Lancet-Lowitja Institute Global Collaboration): a population study.

BACKGROUND International studies of the health of Indigenous and tribal peoples provide important public health insights. Reliable data are required for the development of policy and health services. Previous studies document poorer outcomes for Indigenous peoples compared with benchmark populations, but have been restricted in their coverage of countries or the range of health indicators. Our objective is to describe the health and social status of Indigenous and tribal peoples relative to benchmark populations from a sample of countries. METHODS Collaborators with expertise in Indigenous health data systems were identified for each country. Data were obtained for population, life expectancy at birth, infant mortality, low and high birthweight, maternal mortality, nutritional status, educational attainment, and economic status. Data sources consisted of governmental data, data from non-governmental organisations such as UNICEF, and other research. Absolute and relative differences were calculated. FINDINGS Our data (23 countries, 28 populations) provide evidence of poorer health and social outcomes for Indigenous peoples than for non-Indigenous populations. However, this is not uniformly the case, and the size of the rate difference varies. We document poorer outcomes for Indigenous populations for: life expectancy at birth for 16 of 18 populations with a difference greater than 1 year in 15 populations; infant mortality rate for 18 of 19 populations with a rate difference greater than one per 1000 livebirths in 16 populations; maternal mortality in ten populations; low birthweight with the rate difference greater than 2% in three populations; high birthweight with the rate difference greater than 2% in one population; child malnutrition for ten of 16 populations with a difference greater than 10% in five populations; child obesity for eight of 12 populations with a difference greater than 5% in four populations; adult obesity for seven of 13 populations with a difference greater than 10% in four populations; educational attainment for 26 of 27 populations with a difference greater than 1% in 24 populations; and economic status for 15 of 18 populations with a difference greater than 1% in 14 populations. INTERPRETATION We systematically collated data across a broader sample of countries and indicators than done in previous studies. Taking into account the UN Sustainable Development Goals, we recommend that national governments develop targeted policy responses to Indigenous health, improving access to health services, and Indigenous data within national surveillance systems.

Risk factors for postcesarean surgical site infection.

Objective To determine postcesarean complications and identify independent risk factors for surgical site infection. Methods We studied a cohort of 969 women delivered by cesarean between May and August 1997. Infections were determined by examinations during ward rounds, reviews of laboratory results, and follow-up for 30 days after discharge. Risk factors were identified by multiple logistic regression. Results Surgical complications were rare. There were febrile morbidity and infection complications in 16.2% and 12.4% of subjects, respectively. Eighty-five subjects had 95 surgical site infections (9.8%), and seven risk factors were independently associated with infection. Risk factors included preoperative remote infection (adjusted odd ratio [OR] 16.5, 95% confidence interval [CI] 2.1, 128.3); chorioamnionitis (OR 10.6, 95% CI 2.1, 54.2); maternal preoperative condition (OR 5.3 for those with severe systemic disease [American Society of Anesthesiologists score ≥3], 95% CI 1.2, 24.0); preeclampsia (OR 2.3, 95% CI 1.1, 4.9); higher body mass index (OR 2.0 for every five-unit increment, 95% CI 1.3, 3.0); nulliparity (OR 1.8, 95% CI 1.1, 3.2); and increased surgical blood loss (OR 1.3 for every 100-mL increment, 95% CI 1.1, 1.5). Conclusion Host susceptibility and existing infections were important predictors of surgical site infection after cesarean delivery. Further intervention should target this high-risk group to reduce the clinical effect of surgical site infection.

Workplace violence directed at nursing staff at a general hospital in southern Thailand

Workplace Violence Directed at Nursing Staff at a General Hospital in Southern Thailand: Chalermrat Kamchuchat, et al. Department of Community Medicine, Faculty of Medicine, Prince of Songkla University, Thailand—This study aimed to document the characteristics of workplace violence directed at nursing staff, an issue which has rarely been studied in a developing country. Two study methods, a survey and a key informant interview, were conducted at a general hospital in southern Thailand. A total of 545 out of 594 questionnaires sent were returned for statistical analysis (response rate=91.7%). The 12‐month prevalence of violence experience was 38.9% for verbal abuse, 3.1% for physical abuse, and 0.7% for sexual harassment. Psychological consequences including poor relationships with colleagues and family members were the major concerns. Patients and their relatives were the main perpetrators in verbal and physical abuse while co‐workers were the main perpetrators in cases of sexual harassment. Common factors to incidents of violence were psychological setting, illness of the perpetrators, miscommunication, and alcohol use. Logistic regression analysis showed younger age to be a personal risk factor. Working in the out‐patient unit, trauma and emergency unit, operating room, or medical or surgical unit increased the odds of violence by 80%. Training related to violence prevention and control was found to be effective and decreased the risk of being a victim of violence by 40%. We recommend providing training to high risk groups as a means of controlling workplace violence directed at nursing staff.

Health and health-care systems in southeast Asia: diversity and transitions.

Summary Southeast Asia is a region of enormous social, economic, and political diversity, both across and within countries, shaped by its history, geography, and position as a major crossroad of trade and the movement of goods and services. These factors have not only contributed to the disparate health status of the regions diverse populations, but also to the diverse nature of its health systems, which are at varying stages of evolution. Rapid but inequitable socioeconomic development, coupled with differing rates of demographic and epidemiological transitions, have accentuated health disparities and posed great public health challenges for national health systems, particularly the control of emerging infectious diseases and the rise of non-communicable diseases within ageing populations. While novel forms of health care are evolving in the region, such as corporatised public health-care systems (government owned, but operating according to corporate principles and with private-sector participation) and financing mechanisms to achieve universal coverage, there are key lessons for health reforms and decentralisation. New challenges have emerged with rising trade in health services, migration of the health workforce, and medical tourism. Juxtaposed between the emerging giant economies of China and India, countries of the region are attempting to forge a common regional identity, despite their diversity, to seek mutually acceptable and effective solutions to key regional health challenges. In this first paper in the Lancet Series on health in southeast Asia, we present an overview of key demographic and epidemiological changes in the region, explore challenges facing health systems, and draw attention to the potential for regional collaboration in health.

Prevalence and management of diabetes and associated risk factors by regions of Thailand: Third National Health Examination survey 2004

OBJECTIVE—The aim of this study was to determine the prevalence of diabetes and impaired fasting glucose (IFG) and their association with cardiovascular risk factors and to evaluate the management of blood glucose, blood pressure, and cholesterol in individuals with diabetes by geographical regions of Thailand. RESEARCH DESIGN AND METHODS—With the use of a stratified, multistage sampling design, data from a nationally representative sample of 37,138 individuals aged ≥15 years were collected using questionnaires, physical examination, and blood samples. RESULTS—The prevalence of diabetes and IFG weighted to the national 2004 population was 6.7% (6.0% in men and 7.4% in women) and 12.5% (14.7% in men and 10.4% in women), respectively. Diabetes was more common in urban than in rural men but otherwise prevalence was relatively uniform across geographical regions. In more than one-half of those with diabetes, the disease had not been previously diagnosed, although the majority of those with diabetes were treated with oral antiglycemic agents or insulin. The prevalence of associated risk factors was high among individuals with diabetes as well as those with IFG. Two-thirds of those with diabetes and concomitant high blood pressure (≥130/80 mmHg) were not aware that they had high blood pressure, and >70% of those with diabetes and concomitant high cholesterol (total cholesterol ≥6.2 mmol/l) were not aware that they had high cholesterol. CONCLUSIONS—The prevalences of diabetes and IFG were uniformly high in all regions. Improvements in prevention, diagnosis, and treatment of diabetes and associated risk factors are required if the health burden of diabetes in Thailand is to be averted.

Prevalence and management of prehypertension and hypertension by geographic regions of Thailand: the Third National Health Examination Survey, 2004.

Objective To determine the prevalence of prehypertension and hypertension, and management of hypertension, by geographic regions of Thailand. Methods Using a stratified, multistage sampling design, data from a nationally representative sample of 39 290 individuals aged ≥ 15 years were collected by interview, physical examination and blood sample. Results The prevalence of hypertension and prehypertension weighted to the national 2004 population was 22.0% [95% confidence interval (CI) = 20.5–23.6] and 32.8% (95% CI = 31.5–34.1), respectively, with a higher prevalence in men compared to women. Hypertension was more common in urban compared to rural men, but similar between urban and rural women. Despite some variation, the prevalence of hypertension and prehypertension was relatively uniform across geographical regions. Of those identified as having hypertension in the survey, 69.8% (95% CI = 67.8–71.7) were unaware that they had hypertension. Although the majority of those who were aware (78.2%; 95% CI = 75.8–80.5) had taken blood pressure-lowering drugs in the last 2 weeks, of these only 36.6% (95% CI = 33.3–40.0) had blood pressure < 140/90 mmHg. Rural populations and those from the economically poorer Northeast region were more likely to be unaware that they had hypertension. Conclusion Compared to previous surveys, the prevalence of hypertension and prehypertension is rising rapidly, and is spread relatively evenly across regions of Thailand. Levels of awareness of hypertension were low across the country. A challenging task remains in improving screening, treatment and control of hypertension at the same time as promoting healthier lifestyles.

Environmental factors and incidence of dengue fever and dengue haemorrhagic fever in an urban area, Southern Thailand

Using the enumeration district (ED) block level this study looked at the incidence of dengue fever and dengue haemorrhagic fever (DF/DHF) within the Songkhla municipality in Thailand. Each of the 146 blocks in this area were considered as study units and surveyed for their environmental characteristics. A total of 287 cases of DH/DHF occurring in the year 1998 were selected for this study and the location of their homes mapped. Clustering analysis showed point clustering of the homes (P<0.0001) which was probably due to high density habitation, without any actual prevalence of case clustering. There was no evidence of clustering of the ED blocks with an incidence of DF/DHF (P=0.32). DF/DHF incidence for each block was strongly associated with the percentages of shop-houses, brick-made houses and houses with poor garbage disposal (all P<0.01). DF/DHF control should be emphasized for the areas which have a predominance of these housing types.
