RESUMEN
OBJECTIVES: Nuñoa, Peru has been the site of anthropological research on human adaptability, growth, and health since the 1960s. Previous studies documented a nascent secular trend in growth between 1964 and 1984. However, no secular trend was evident when the population was re-examined in 1999, following an intervening period of sociopolitical upheaval. Subsequently, the region experienced considerable economic development reflected in secular increases in height. We seek to evaluate trends in growth and BMI among Nuñoan children over 50 years. MATERIALS AND METHODS: Anthropometric data for 929 children collected in 2015 are compared with anthropometric data for 394 children from 1964, 912 children from 1984, and 292 children from 1999. The data were converted to z-scores using the WHO 2007 growth standards. anova is used to evaluate rates of stunting, underweight, overweight, and obesity across the study periods. RESULTS: We observe small increases in stature and weight between the 1960s and 1980s, almost no change between the 1980s and 1990s and statistically significant reductions in stunting and increases in height between the 1990s and 2015. DISCUSSION: There were relatively small differences in stature and weight and a high incidence of stunting between 1964 and 1999 attributed to extremely poor economic and health conditions. A large secular increase in height (7-8 cm on average) and consequent reduction in rates of stunting between 1999 and 2015 occurred due to improved social and economic conditions. In addition to political stabilization, enhanced infrastructure, social aid programs, improved healthcare, and economic expansion contribute to these trends.

The University of Massachusetts Amherst is part of Five-Colleges Inc, a consortium that includes the university and four liberal arts colleges. Consortium faculty from the School of Public Health and Health Sciences at the university and from the colleges are working to bridge liberal arts with public health graduate education. We outline four key themes guiding this effort and exemplary curricular tools for innovative community-based and multidisciplinary academic and research programs. The structure of the consortium has created a novel trajectory for student learning and engagement, with important ramifications for pedagogy and professional practice in public health. We show how graduate public health education and liberal arts can, and must, work in tandem to transform public health practice in the 21st century.

Over the past three decades, tourism-based economic development has transformed social and economic conditions in the Yucatan Peninsula, Mexico. Mayan communities have become directly involved in the changing economy as the main source of inexpensive labor for construction and service jobs at tourism centers, and as sites of ecotourism and archeotourism. In this paper, we address how these macro-processes of change intersect locally with the commoditization of food systems, diets and nutrition in four Yucatec Mayan communities with differing relationships to the tourist economy. Yucatec Mayan diets have become increasingly dependent on purchased foods, and reflect a greater consumption of commercialized processed foods. Coca-Cola, an international icon of US culture, along with other local and internationally owned calorie-dense but nutrient-poor snack foods, is now a common element of Mayan diets, leading to what we call "coca-colonization." The consequences of this diet, likely exacerbated by the increased consumption of snack foods, include an apparent increase in overweight and obese adults as well as signs of growth stunting in children. The Maya we talked with recognize both the potential disruption that tourism brings to all aspects of their lives and the necessity of jobs that tourism creates to meet their families' basic needs.

Over the past 40 years, tourism-based economic development has transformed social and economic conditions in the Yucatan Peninsula, Mexico. We address how these changes have influenced anthropometric indicators of growth and nutritional status in Yalcoba, a Mayan farming community involved in the circular migration of labor in the tourist economy. Data are presented on stature and weight for children measured in 1938 in the Yucatan Peninsula and from 1987 to 1998 in the Mayan community of Yalcoba. In addition, stature, weight and BMI are presented for adults in Yalcoba based on clinic records. Childhood stature varied little between 1938 and 1987. Between 1987 and 1998 average male child statures increased by 2.6cm and female child statures increased by 2.7cm. Yet, 65% of children were short for their ages. Between 1987 and 1998, average child weight increased by 1.8kg. Child BMIs were similar to US reference values and 13% were considered to be above average for weight. Forty percent of adult males and 64% of females were overweight or obese. The anthropometric data from Yalcoba suggest a pattern of stunted children growing into overweight adults. This pattern is found elsewhere in the Yucatan and in much of the developing world where populations have experienced a nutrition transition toward western diets and reduced physical activity levels.
