Inadequate early detection of cervical cancer in the global southResearchers from the Universities of Heidelberg, Stanford and Göttingen as well as the Harvard TH Chan School of Public Health analyzed representative survey data from 55 different countries with low and middle income. In the majority of the countries surveyed (37 out of 55), less than 70 percent of all women reported ever having had a health check-up. The team found a positive correlation between the proportion of women examined and the gross domestic product and health expenditure of a country (relative to the gross domestic product). The lower a country's gross domestic product and health expenditure, the fewer women said they had ever taken part in a preventive medical check-up. In addition, metrics that measure the extent of gender discrimination within a country seem to be related to the number of women who have already participated in a screening test. In order to improve the health systems of the affected countries, the authors suggest taking a look at the recipes for success in countries with a high proportion of preventive medical check-ups and comparatively lower inequalities between population groups. "This is the case, for example, in countries in Latin America and the Caribbean as well as in Bhutan and Moldova," says co-author Prof. Dr. Sebastian Vollmer from the University of Göttingen.

Average detection rate of SARS-CoV-2 infections is estimated around nine percentThe number of confirmed cases for the novel coronavirus disease COVID-19 officially issued by countries and widely commented on by national and international media outlets dramatically understates the true number of infections, a recent report from the University of Göttingen suggests. Dr. Christian Bommer and Professor Dr. Sebastian Vollmer from Göttingen University have used estimates of COVID-19 mortality and time until death from a recent study published in the Lancet Infectious Diseases to test the quality of official case records. Their data shows that the 40 most affected countries have only discovered on average about 9% of coronavirus infections by March 30th (compared to 6% two weeks earlier). Read more.

Anaemia among men in India: a nationally representative cross-sectional studyAn international research team comprising of the Harvard T. H. Chan School of Public Health, the University Heidelberg, the Public Health Foundation of India, the University of Goettingen and more, analyzed the prevalence of anemia among men in India, how it varies across states and compared the findings with the prevalence among women regarding geographical and sociodemographic variation. This cross-sectional study analyzed data from a representative household survey from January 2015 to December 2016, carried out in India’s 29 states and seven Union Territories. This study included more than 106 thousand men and more than 633 thousand women. The findings showed, that men had a prevalence of any anemia with 23.2%, moderate or severe anemia with 5.1% and severe anemia with 0.5%. Men ranging from 20-34 years showed the lowest probability of anemia, which is a similar result to women across age groups. Socio-economic factors like less household wealth, lower education, rural areas, smoking and underweight increase the probability of anemia among men. The outcome showed, that the geographical and sociodemographic variation of anemia is similar regarding men and women, although many studies and interventions have focused on women and children. Future efforts in anemia reduction targeting men can be adjusted to the existing interventions reducing anemia among women.

Inadequate care for high blood pressure patients along the treatment systemA research team composed of academics from Harvard T.H. Chan School of Public Health, the University of Göttingen and the Medical Faculty of Heidelberg and various partner institutions from study countries analyzed the healthcare of hypertension in 44 low- and middle-income countries. They used a model known as the “cascade methodology”. The researchers found that less than half of those affected are diagnosed with high blood pressure. Only 30 percent of these patients are treated and only one tenth have the disease under control. "High blood pressure can be treated relatively well and cheaply," says Sebastian Vollmer, Professor of Development Economics at the University of Göttingen. "Undiagnosed or untreated hypertension, on the other hand, is a considerable risk for the people affected and can lead to significant complications, including death.”

EASAC report “The imperative of climate action to protect human health in Europe”Prof. Dr. Vollmer was part of a European Academies’ Science Advisory Council (EASAC) working group on climate change and health. He was nominated by the National Academy of Sciences Leopoldina. The new EASAC report “The imperative of climate action to protect human health in Europe” highlights an alarming range of health risks due to climate change, and the benefits of rapid phase out of fossil fuels. The scientists elaborated different pathways that will lead to increased health risks if no urgent action is taken to reduce greenhouse emission.
The pathways are increased exposure to high temperatures and extreme events such as floods and droughts, air pollution and allergens; Weakening of food and nutrition security; Increased incidence and changing distribution of some infectious diseases (including mosquito-borne, food-borne and water-borne diseases); Growing risk of forced migration;
The solutions proposed by the scientists of the EASAC were decarbonization of the economy, healthier diets, climate-smart food systems, strengthening communicable disease surveillance and response systems. Furthermore, the impacts of climate change should not only be viewed on the European level, but rather on the global level.

Variation in health system performance for managing diabetes among states in India: A cross-sectional study of individuals aged 15 to 49 yearsIn this study, Prenissl et al. determined the proportion of adults with diabetes in India who have reached each step of the care cascade. Moreover, they analyzed the variation of these cascade indicators among states and socio-demographic groups. This analysis included 729,829 participants. Among those with diabetes (19,453 participants), 52.5% (95% CI, 50.6–54.4%) were “aware”, 40.5% (95% CI, 38.6–42.3%) “treated”, and 24.8% (95% CI, 23.1–26.4%) “controlled”. Living in a rural area, male sex, less household wealth, and lower education were associated with worse care cascade indicators. The greatest loss in the care cascade takes place at the awareness stage.

Hypertension screening, awareness, treatment, and control in India: A nationally representative cross-sectional study among individuals aged 15 to 49 yearsNon communicable diseases are increasingly important in low and middle income countries worldwide. This study analyzed health care systems in 44 low and middle-income countries focusing on the performance of hypertension care. Thus, only 45 percent of people are aware of their diagnosis, as this first large-scale population-based study of hypertension care shows. The study is based on STEPS-data of the World Health Organization (WHO) and other nationally representative data. The findings highlight the vital need for improvements in several health care systems. It shows, that less than half of those who are affected are diagnosed with hypertension. Treatment is given to one-third of the patients and only one-tenth gained control of the disease. Hypertension is a major risk factor regarding stroke, heart attacks, and resulting deaths. Lacking awareness and insufficient treatment have lifted hypertension to one of the most common non-communicable diseases. Besides the improvement of health systems and treatment, awareness and information of the public have to be raised. Thus promising diagnosis, treatment and easy control of this disease, the results picture a low performance in several healthcare systems.

Geographic and sociodemographic variation of cardiovascular disease risk in India: A cross-sectional study of 797,540 adultsThis study aimed to determine how Cardiovascular disease (CVD) risk—and the factors that determine risk—varies among states in India, by rural-urban location, and by individual-level sociodemographic characteristics. For that purpose, two large household surveys carried out between 2012 and 2014, which included a sample of 797,540 adults aged 30 to 74 years across India were used. Different risk scores were used as outcome variables, that were: the Framingham risk score, Harvard–NHANES, Globorisk, and WHO–ISH scores. CVD risk tended to be highest in North, Northeast, and South India. Similarly, household wealth quintile and living in an urban area were positively associated with CVD risk among both sexes, but the associations were stronger among women than men. Also, for our other sociodemographic characteristics, we found significant differences.

Diabetes and hypertension in India: A nationally representative study of 1.3 million adultsIn this paper we addressed the question of how the prevalence of diabetes and hypertension in India vary by geographical area and sociodemographic characteristics. The conducted population-based study was cross-sectional and nationally representative. It was carried out between 2012 and 2014. A total of 1.320.555 adults 18 years or older with plasma glucose (PG) and blood pressure (BP) measurements were included in the analysis. The main outcome variables were diabetes and hypertension. The crude prevalence of diabetes and hypertension was 7.5% (95% CI, 7.3%-7.7%) and 25.3% (95% CI, 25.0%-25.6%), respectively. Being in the richest household wealth quintile compared with being in the poorest quintile was associated with only a modestly higher probability of diabetes (rural: 2.81 percentage points; 95% CI, 2.53-3.08 and urban: 3.47 percentage points; 95% CI, 3.03-3.91) and hypertension (rural: 4.15 percentage points; 95% CI, 3.68-4.61 and urban: 3.01 percentage points; 95% CI, 2.38-3.65). There were large differences in diabetes and hypertension rates between states. Education seemed to have a rather negligible effect.

The Global Economic Burden of Diabetes in Adults aged 20 to 79: A Cost-of-Illness StudyThe WHO 2016 Global Report on Diabetes estimates that over 420 million adults are living with diabetes. The growing prevalence of diabetes, specifically in low- and middle-income countries, reveals the massive shifts in health trends since the 1990s. In cooperation with an international team of scientists, economists Christian Bommer, Esther Heesemann, Vera Sagalova and Prof. Sebastian Vollmer from the University of Göttingen have calculated that in 2015 the worldwide economic burden of diabetes reached $1.3 trillion or 1.8 percent of the global GDP. The results of the study are published in the Lancet Diabetes & Endocrinology. In a follow-up study that was published in Diabetes Care the team has projected the global economic burden of diabates until 2030. The economic burden is projected to increase even under the most optimistic scenario that SDG targets are met.

The Association of Parental Education with Childhood Undernutrition in Low- and Middle-Income Countries: Comparing the Role of Paternal and Maternal EducationA team comprising Sebastian Vollmer, Christian Bommer, Aditi Krishna, Kenneth Harttgen and SV Subramanian systematically investigated the differences in maternal and paternal education and their association with childhood undernutrition. For this paper, they used 180 Demographic and Health Surveys (DHS) from 62 countries, and covering the years 1990 to 2014, they show that both higher maternal and paternal education levels are associated with lower childhood undernutrition with maternal education being the stronger determinant in specifications failing to adjust for household wealth and local area characteristics. However, when these controls are introduced, the observed differences are strongly weakened or disappear entirely. The findings suggest that paternal education is also an important factor for reducing childhood undernutrition and should therefore receive increased attention in the literature.

Monks, Gents and Industrialists : the Long Run Impact of the Dissolution of the English MonasteriesIn the late medieval period the overwhelming majority of land in England was held by the Crown, the Aristocracy and the Church. In two acts passed in 1532 and 1534 Parliament made Henry VIII, head of the Church. At first, Henry’s objective was to redirect the revenues that the monastries paid to the Pope to himself. So, he ordered a survey of church incomes the Valor Ecclesiasticus just shortly before it was decided to dissolve all monasteries. This paper investigated the long-run economic impact of the Dissolution of the monasteries in England. To measure the impact of the Dissolution at the parish level we digitized the Valor Ecclesiasticus. We then showed that the greater was monastic income according to the Valor, the more industrialization there was in 1838 in terms of the presence and number of textile mills and the number of mill employees. We also showed that greater levels of monastic income in 1535 were associated with a smaller proportion of the labor force employed in agriculture according to the 1831 Census, and a larger share of the labor force employed in manufacturing and retail. Furthermore, we explored some of the likely channels via which the Dissolution might have impacted industrialization.

HIV surveys in older adults: better data, better healthMost nationally representative HIV surveys, including those of the Demographic and Health Surveys Programme, limit eligibility for HIV testing to adults younger than 50 years or 55 years of age. These age limits reflect the belief that HIV is a disease acquired in youth and with consequences in middle age. However, as the epidemic evolves, information about HIV in older people will become essential, and age limits for surveys should be removed for six reasons which we discuss in the paper.

Association between economic growth and early childhood undernutrition: evidence from 121 Demographic and Health Surveys from 36 low-income and middle-income countriesIn this paper, evidence has been provided that merely economic growth is not enough for the improvement of early childhood undernutrition. The sample consisted of nationally representative cross-sectional surveys of children aged 0–35 months, and the outcome variables were stunting, underweight, and wasting. The main independent variable was per-head gross domestic product (GDP) in constant prices and adjusted for purchasing power parity. Logistic regression models were run to estimate the association between changes in per-head GDP and changes in child undernutrition outcomes. Models were adjusted for country fixed effects, survey-year fixed effects, clustering, and demographic and socioeconomic covariates for the child, mother, and household. A quantitatively very small to null association was observed between increases in per-head GDP and reductions in early childhood undernutrition. The findings emphasize the need for direct health investments to improve the nutritional status of children in low-income and middle-income countries.

An African Growth Miracle? Or: What do Asset Indices Tell us about Trends in Economic Performance?Using changes in the possession of household assets over the past 20 years, several recent papers have argued that economic growth and poverty reduction in Africa was substantially better than suggested by national income data and income poverty statistics, which suffer from well-known weaknesses. In this paper, we scrutinize these claims and first argue that trends in assets provide biased proxies for trends in incomes or consumption. In particular we show that the relationship between growth in assets and growth in incomes or consumption is extremely weak; instead, we find evidence of asset drift using macro and micro data, which is consistent with the claims we make about possible biases in the use of asset indices. As a result, we find no evidence supporting the claim of an African growth miracle that extends beyond what has been reported in official GDP/capita and consumption figures.

Long-Run Trends of Human Aging and LongevityIn this paper, we ask whether future improvements of life expectancy will be bounded from above by human life span. Life span, in contrast to life expectancy, is conceptualized as a biological measure of longevity driven by the intrinsic rate of bodily deterioration. From these observations, it should be clear that life span, in contrast to life expectancy, cannot be defined as a mere statistical measure without biological foundation. Hence, we have introduced to the economic science a theoretical foundation of human life span based on two strong empirical regularities, the Gompertz–Makeham law and the compensation effect of mortality. Our results showed that contemporaneous humans start out as young adults much more healthy than their forefathers a century ago but they are also aging faster. For a long time of our history, this trend was consistent with the observation of rising life expectancy under an invariant life span. If life span was indeed immutable, as it presumably is for other animals, future improvements in life expectancy would soon end. Life expectancy, as we have shown in this paper, is bounded from above by life span. For the second half of the twentieth century, however, we were able to present evidence for an expanding life span of about 8 years.
