- Body-mass index (BMI) has increased steadily in most countries in parallel with a rise in the proportion of the population who live in cities(.)(1,2) This has led to a widely reported view that urbanization is one of the most important drivers of the global rise in obesity(3-6). Here we use 2,009 population-based studies, with measurements of height and weight in more than 112 million adults, to report national, regional and global trends in mean BMI segregated by place of residence (a rural or urban area) from 1985 to 2017. We show that, contrary to the dominant paradigm, more than 55% of the global rise in mean BMI from 1985 to 2017-and more than 80% in some low- and middle-income regions-was due to increases in BMI in rural areas. This large contribution stems from the fact that, with the exception of women in sub-Saharan Africa, BMI is increasing at the same rate or faster in rural areas than in cities in low- and middle-income regions. These trends have in turn resulted in a closing-and in some countries reversal-of the gap in BMI between urban and rural areas in low- and middle-income countries, especially for women. In high-income and industrialized countries, we noted a persistently higher rural BMI, especially for women. There is an urgent need for an integrated approach to rural nutrition that enhances financial and physical access to healthy foods, to avoid replacing the rural undernutrition disadvantage in poor countries with a more general malnutrition disadvantage that entails excessive consumption of low-quality calories.

- Optimal growth and development in childhood and adolescence is crucial for lifelong health and well-being1–6. Here we used data from 2,325 population-based studies, with measurements of height and weight from 71 million participants, to report the height and body-mass index (BMI) of children and adolescents aged 5–19 years on the basis of rural and urban place of residence in 200 countries and territories from 1990 to 2020. In 1990, children and adolescents residing in cities were taller than their rural counterparts in all but a few high-income countries. By 2020, the urban height advantage became smaller in most countries, and in many high-income western countries it reversed into a small urban-based disadvantage. The exception was for boys in most countries in sub-Saharan Africa and in some countries in Oceania, south Asia and the region of central Asia, Middle East and north Africa. In these countries, successive cohorts of boys from rural places either did not gain height or possibly became shorter, and hence fell further behind their urban peers. The difference between the age-standardized mean BMI of children in urban and rural areas was <1.1 kg m–2 in the vast majority of countries. Within this small range, BMI increased slightly more in cities than in rural areas, except in south Asia, sub-Saharan Africa and some countries in central and eastern Europe. Our results show that in much of the world, the growth and developmental advantages of living in cities have diminished in the twenty-first century, whereas in much of sub-Saharan Africa they have amplified.

- Background The use of games for social skill development in the classroom is accelerating at a tremendous rate. At the same time, the research surrounding games designed for teaching social skills remains fragmented. This systematic review summarizes the current existing literature on social skill serious games for young people ages 5 to 19 and is the first review of serious games to note the demographic and geographic component of these studies. Method This review included papers that: evaluated a game designed to teach social skills; included measurable, quantitative outcomes; have a translation or be published in English; were peer-reviewed; date from January 2010 to May 2020; and have a nonclinical study population between ages of 5 to 19. Keywords were obtained from the CASEL 5 framework. Results Our findings are mixed but suggest that serious games may improve social skills when used alongside in-person discussion. We also found potential effects of the length of time of gameplay, intervention, and follow-up on social skill serious game effectiveness. Although this review found promising research conducted in East Asian countries and with minority samples in the United States, the majority of social skill serious game research takes place in the United States and Australia, with unreported demographic information and white-majority samples. Conclusions Due to the limited number of published studies in this area and studies lacking methodological rigor, the effectiveness of using games to teach social skills and the impact of background on social skill learning require further discussion.

- Ideally, both ecosystem service and human development policies should improve human well-being through the conservation of ecosystems that provide valuable services. However, program costs and benefits to multiple stakeholders, and how they change through time, are rarely carefully analyzed. We examine one of China's new ecosystem service protection and human development policies: the Relocation and Settlement Program of Southern Shaanxi Province (RSP), which pays households who opt voluntarily to resettle from mountainous areas. The RSP aims to reduce disaster risk, restore important ecosystem services, and improve human well-being. We use household surveys and biophysical data in an integrated economic cost-benefit analysis for multiple stakeholders. We project that the RSP will result in positive net benefits to the municipal government, and to cross-region and global beneficiaries over the long run along with environment improvement, including improved water quality, soil erosion control, and carbon sequestration. However, there are significant short-run relocation costs for local residents so that poor households may have difficulty participating because they lack the resources to pay the initial costs of relocation. Greater subsidies and subsequent supports after relocation are necessary to reduce the payback period of resettled households in the long run. Compensation from downstream beneficiaries for improved water and from carbon trades could be channeled into reducing relocation costs for the poor and sharing the burden of RSP implementation. The effectiveness of the RSP could also be greatly strengthened by early investment in developing human capital and environment-friendly jobs and establishing long-term mechanisms for securing program goals. These challenges and potential solutions pervade ecosystem service efforts globally.

- Objective: Previous research has shown that self-esteem is associated with academic achievement. However, few studies have used longitudinal data to examine how self-esteem and achievement co-develop over a long time span, and even fewer have focused on ethnic minority youth. Method: We used data from a longitudinal study of Mexican-origin youth (N=674) to examine the bidirectional associations between self-esteem and academic achievement from 5th to 11th grade. Global and domain-specific self-esteem (academic, honesty, peer relationships, appearance) were assessed at ages 10, 12, 14, and 16 using Marsh et al.'s (2005) Self-Description Questionnaire. Academic achievement was assessed at the same ages using self-reported grades and standardized test scores from school records. Results: Youth with high global and academic self-esteem showed relative improvements in their grades (but not test scores), and youth who received higher grades and test scores showed relative increases in global and academic self-esteem. Youth with high honesty self-esteem showed relative increases in grades and test scores, and youth with higher grades showed relative increases in peer relationship self-esteem. Conclusion: Students who feel better about themselves tend to show improvements in their grades, and getting better grades and test scores promotes more positive self-views.
