Abstract
BACKGROUND Little has been done to establish biobanks for studying the environment and lifestyle risk factors for diseases among the school-age children. The Minhang Pediatric Biobank (MPB) cohort study aims to identify factors associated with health and diseases of school-aged children living in the urban or suburban area of Shanghai. METHODS This population-based cohort study was started in all sub-districts/towns of Minhang district of Shanghai in 2014. First-grade students in elementary school were enrolled during the time of their routine physical examinations, with self-administered questionnaires completed by their primary caregivers. Additional information was extracted from multiple health information systems. Urine and saliva samples were collected during the baseline survey and follow-up visits. RESULTS At the end of 2014 academic year, a total number of 8412 children and their parents were recruited, including 4339 boys and 4073 girls. All the participants completed the baseline survey and physical examination, and 7128 urine and 2767 saliva samples were collected. The five most prevalent childhood diseases in this population were dental caries, bronchitis, pneumonia, asthma and overweight/obese. CONCLUSIONS The MPB cohort has been successfully established, serving as a useful platform for future research relating to the genetic, environmental and lifestyle risk factors for childhood diseases.

Geographical and sociodemographic disparities in fruit and vegetables consumption among adults in Burkina Faso: baseline results from the 2013 WHO STEPS survey. BMC Public Health 2023; 23:2245. [PMID: 37964247 PMCID: PMC10644490 DOI: 10.1186/s12889-023-17118-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2022] [Accepted: 10/31/2023] [Indexed: 11/16/2023] Open
Abstract
BACKGROUND Evidence on sociodemographic determinants and spatial variations in the fruit and/or vegetable (FV) consumption was reported. This study aimed to explore geographical and sociodemographic disparities in the level of FV consumption among adults in Burkina Faso, using the national baseline data. METHODS This was a cross-sectional secondary study of primary data obtained by the 2013 (September to October) World Health Organization Stepwise Approach to Surveillance survey conducted in Burkina Faso. The participants were 4402 women and men aged 25-64 years and living in all 13 Burkinabè Regions. Descriptive and analytical analyses were performed using Student's t test, ANOVA, the chi-square test, Fisher's exact test and logistic regressions. RESULTS The prevalence of a typical daily consumption of at least three servings was 4.1% (95% CI: 3.6-4.8) for fruits and 6.6% (95% CI: 5.9-7.3) for vegetables. The national prevalence of adequate FV intake was 5.1% (95% CI: 4.4-5.8), and for two Regions ("Centre-Ouest" and "Nord") the pooled prevalence was 22.4%, while in the other eleven Regions its was significantly lower, 2.4% (p = 0.0001). Using quartiles derived from the national level of consumption, each of these two Regions had a higher proportion (about 50%) of their participants in the fourth quartile (the higher level). The associated sociodemographic factors with the adequate intake were being rural residents (aOR = 1.7, p = 0.011) and women (aOR = 1.3; p = 0.03). CONCLUSION Except for the Regions of "Centre-Ouest" and "Nord" of Burkina Faso, the prevalence of adequate consumption of FV was very low in its other eleven Regions. Measures to increase consumption in urban people are urgent while women should be the key actor in the family-based approaches implementation and the nutrition education promoting FV consumption.

Abstract
Globally, the literature tends to emphasize negative associations between socioeconomic status (SES) and bodyweight in countries improving their economic development. However, little is known about the social distribution of obesity in sub-Saharan Africa (SSA) where economic growth has been highly heterogeneous the last decades. This paper reviews an exhaustive set of recent empirical studies examining its association in low-income and lower-middle-income countries in SSA. Although there is evidence of a positive association between SES and obesity in low-income countries, we found mixed associations in lower-middle-income countries, potentially providing evidence of a social reversal of the obesity burden.

Abstract
INTRODUCTION The global obesity epidemic and its adverse health effects have reached sub-Saharan Africa. In some urban settings, like Burkina Faso's capital Ouagadougou, up to 43% of the adult population are overweight or obese. At the same time, modernised food systems are responsible for 26% of global greenhouse gas emissions, 50% of land use and 70% of freshwater use. International guidelines on the treatment of overweight and obesity recommend dietary intervention programmes that promote reduced calorie intake and increased physical activity. So far, weight loss interventions rarely consider sustainable dietary concepts, including healthfulness, affordability, cultural appropriateness and environmental friendliness. Therefore, we present a study protocol of a novel randomised controlled trial that aims to establish the effects of a sustainable weight loss intervention on cardiometabolic and environmental outcomes in urban Burkina Faso. METHODS AND ANALYSIS We conduct a non-blinded randomised controlled trial, comparing a 6-month sustainable diet weight loss intervention programme (n=125) with a standard weight loss information material and 5 min oral counselling at baseline (n=125). Primary outcome is a reduction in fasting plasma glucose of ≥0.1 mmol/L. Outcome measures are assessed at baseline, after 6 months and after 12 months. ETHICS AND DISSEMINATION Ethical approval for the study has been obtained from the Medical Faculty of Heidelberg University (S-376/2019) and from the Ministry of Health and the Ministry of Higher Education, Scientific Research and Innovation in Ouagadougou, Burkina Faso (No 2021-01-001). The results of the study will be disseminated to local stakeholders at a final project meeting and to the wider research community through peer-reviewed publications and conferences.

Abstract
Background Cardiovascular disease (CVD) risk assessment is a critical step in the current approach to the primary prevention of CVD, particularly in low-income countries such as Burkina Faso. In this study, we aimed to assess the geographic and sociodemographic disparities of the ten-year cardiovascular risk in Burkina Faso. Methods We conducted a secondary analysis of the data from the first nationwide survey using the World Health Organization (WHO) STEPwise approach. Ten-year cardiovascular risk was determined using the WHO 2019 updated risk chart (WHO risk) as main outcome, and the Framingham risk score (FRS) and the Globorisk chart for secondary outcomes. We performed a modified Poisson regression model using a generalized estimating equation to examine the association between CVD risk and sociodemographic characteristics. Results A total of 3081 participants aged 30 to 64 years were included in this analysis. The overall age and sex-standardized mean of absolute ten-year cardiovascular risk assessed using the WHO risk chart was 2.5% (95% CI: 2.4–2.6), ranging from 2.3% (95% CI: 2.2–2.4) in Centre Est to 3.0% (95% CI: 2.8–3.2) in the Centre region. It was 4.6% (95% CI: 4.4–4.8) for FRS and 4.0% (95% CI: 3.8–4.1) for Globorisk. Regarding categorized CVD risk (absolute risk ≥10%), we found out that the age and sex-standardized prevalence of elevated risk was 1.7% (95% CI: 1.3–2.1) for WHO risk, 10.4% (95% CI: 9.6–11.2) for FRS, and 5.9% (95% CI: 5.1–6.6) for Globorisk. For all of the three risk scores, elevated CVD risk was associated with increasing age, men, higher education, urban residence, and health region (Centre). Conclusion We found sociodemographic and geographic inequalities in the ten-year CVD risk in Burkina Faso regardless of risk score used. Therefore, population-wide interventions are needed to improve detection and management of adult in the higher CVD risk groups in Burkina Faso.

Abstract
China is at a stage of rapid urbanization over the past decades, and the association of urbanization with cardiovascular disease has been confirmed by previous studies. However, few studies assessed the association of urbanization with cardiovascular risk factors, especially in Chinese population. We conducted a cross-sectional, populational-based study, using data from China Health and Nutrition Survey (CHNS) in 2009. The logistic regression was used to assess the association of urbanization measured by urban index with cardiovascular risk factors (diabetes mellitus, hypertension, dyslipidemia, obesity, smoking, physical activity and fruits and vegetables consumption), varied with sex. The current study included 18,887 participants enrolled (mean age 39.8 ± 19.8 years; 52.2% female) who live in China. In regression model, the urban index was significantly associated with the variations of cardiovascular risk factors for male, including diabetes (OR 1.34, 95% CI: 1.22-1.48), hypercholesterolemia (OR 1.15, 95% CI: 1.09-1.22), never smoking (OR 0.92, 95% CI: 0.89-0.96), higher fruits and vegetables consumptions (OR 0.93, 95% CI: 0.87-0.99), higher body mass index (BMI) (OR 1.16, 95% CI: 1.10-1.22), and higher physical activity (OR 0.69, 95% CI: 0.66-0.73). Compared with the male, the associations of urban index with cardiovascular risk factors for female were similar, but not for BMI (OR 1.00, 95% CI: 0.96-1.05). The present finding emphasizes the changes of cardiovascular risk factors associated with urbanization in China, and indicated that close attention should be paid to the risk of hypercholesterolemia, diabetes and men's obesity in the process of urbanization.

Abstract
PURPOSE The Shanghai Suburban Adult Cohort and Biobank (SSACB) was established to identify environmental, lifestyle and genetic risk factors for non-communicable chronic diseases (NCDs) in adults (20-74 years old) living in a suburban area of Shanghai with rapid urbanisation. PARTICIPANTS Two of eight suburban district were purposely selected according to participant willingness, health service facilities, population, geographic region and electronic medical record system. From these suburban districts, four communities were selected based on economic level and population size. At stage three, one-third of the committees/villages were randomly selected from each community. All residents aged 20-74 years old were invited as study participants. FINDINGS TO DATE The baseline data on demographics, lifestyle and physical health-related factors were collected using a face-to-face questionnaire interview. All participants completed physical examinations and had blood and urine tests. Blood and urine samples from these tests were stored in a biobank. From 6 April 2016 through 31 October 2017, we conducted face-to-face interviews and clinical examinations in 44 887 participants: 35 727 from Songjiang District and 9160 from Jiading District. The average age of participants was 56.4±11.2 years in Songjiang and 56.6±10.5 years in Jiading. The prevalence of hypertension, diabetes and dyslipidaemia was 34.0%, 8.2% and 11.1%, respectively. FUTURE PLANS In-person surveys will be conducted every 5 years. For annual tracking, baseline data was linked to the local health information system, which was composed of an electronic medical record system, a chronic disease management system, a cancer registry system, an infectious disease report system and a death registry system. The data of the SSACB cohort is located in the School of Public Health, Fudan University. International and domestic collaborative research projects are encouraged and inherent in the project.

Abstract
Understanding the spatiotemporal dynamics of urbanization and predicting future growth is now essential for sustainable urban planning and policy making. This study explores future urban expansion in the rapidly growing region of eastern lowland Nepal. We used the hybrid cellular automata-Markov (CA-Markov) model, which utilizes historical land use and land cover (LULC) maps and several biophysical change driver variables to predict urban expansion for the years 2026 and 2036. Transitional area matrices were generated based on historical LULC data from 1996 to 2006, from 2006 to 2016, and from 1996 to 2016. The approach was validated by cross comparing the actual and simulated maps for 2016. Evaluation gave satisfactory values of Kno (0.89), Kstandard (0.84), and Klocation (0.89) which verifies the accuracy of the model. Hence, the CA-Markov model was utilized to simulate the LULC map for the years 2026 and 2036. The study area experienced rapid peri/urban expansion and sharp decline in area of cultivated land during 1989-2016. Built-up area increased by 110.90 km2 over a period of 27 years at the loss of 87.59 km2 cultivated land. Simulation analysis indicates that urban expansion will continue with urban cover increasing to 230 km2 (8.95%) and 318.51 km2 (12.45%) by 2026 and 2036, respectively, with corresponding declines in cultivated land to 1453.83 km2 (56.86%) and 1374.93 km2 (53.77%) for the same years. The alarming increase in urban areas coupled with loss of cultivated land will have negative implications for food security and environmental equilibrium in the region.

Abstract
Urbanization is associated with higher prevalence of cardiovascular disease worldwide. Aortic stiffness, as measured by carotid-femoral pulse wave velocity is a validated predictor of cardiovascular disease. Our objective was to determine the association between urbanization and carotid-femoral pulse wave velocity. The analysis included 6166 participants enrolled in an ongoing population-based study (mean age 42 years; 58% female) who live in an 80 × 80 km region of southern India. Multiple measures of urbanization were used and compared: 1) census designations, 2) satellite derived land cover (crops, grass, shrubs or trees as rural; built-up areas as urban), and 3) distance categories based on proximity to an urban center. The association between urbanization and carotid-femoral pulse wave velocity was tested in sex-stratified linear regression models. People residing in urban areas had significantly (p < 0.05) elevated mean carotid-femoral pulse wave velocity compared to non-urban populations after adjustment for other risk factors. There was also an inverse association between distance from the urban center and mean carotid-femoral pulse wave velocity: each 10 km increase in distance was associated with a decrease in mean carotid-femoral pulse wave velocity of 0.07 m/s (95% CI: -0.09, -0.06 m/s). The association was stronger among older participants, among smokers, and among those with other cardiovascular risk factors. Further research is needed to determine which components in the urban environment are associated with higher carotid-femoral pulse wave velocity.

Abstract
PURPOSE OF REVIEW Outline recent epidemiologic data regarding hypertension in developing countries, distinguish differences from developed countries, and identify challenges in management and future perspectives. RECENT FINDINGS Increased sugar intake, air and noise pollution, and low birth weight are emerging hypertension risk factors. The major challenges in management are difficulties in accurate diagnosis of hypertension and adequate blood pressure control. In contrast to developed countries, hypertension prevalence rates are on the rise in developing countries with no improvement in awareness or control rates. The increasing burden of hypertension is largely attributable to behavioral factors, urbanization, unhealthy diet, obesity, social stress, and inactivity. Health authorities, medical societies, and drug industry can collaborate to improve hypertension control through education programs, public awareness campaigns, legislation to limit salt intake, encourage generic drugs, development and dissemination of national guidelines, and involving nurses and pharmacists in hypertension management. More epidemiologic data are needed in the future to identify reasons behind increased prevalence and poor blood pressure control and examine trends in prevalence, awareness, treatment, and control. National programs for better hypertension control based on local culture, economic characteristics, and available resources in the population are needed. The role of new tools for hypertension management should be tested in developing world.
