Nutrition Transition and the Global Diabetes Epidemic.
Current diabetes reports, 2015Co-Authors: Barry M. PopkinAbstract:Low- and middle-income countries (LMICs) face a rapid change in the Nutrition Transition toward increases in noncommunicable diseases. Underlying this Transition are shifts in the agricultural system and the subsequent growth of the modern retail and food service sectors across all regions and countries, a change in technology affecting physical activity and inactivity, mass media access, urbanization, and penetration of modern food systems into all societies. The resulting major shifts in diet are toward increased refined carbohydrates, added sweeteners, edible oils, and animal-source foods and reduced legumes, other vegetables, and fruits. Most countries are seeing increases in body mass index (BMI), overweight, and waist circumference (WC), and an increased WC-BMI ratio appears to be emerging in many regions. The implications of these rapidly changing diets and body compositions include the prevalence and severity of diabetes in LMICs.

the Nutrition Transition new trends in the global diet
Nutrition Reviews, 2009Co-Authors: Adam Drewnowski, Barry M. PopkinAbstract:Analyses of economic and food availability data for 1962–1994 reveal a major shift in the structure of the global diet marked by an uncoupling of the classic relationship between incomes and fat intakes. Global availability of cheap vegetable oils and fats has resulted in greatly increased fat consumption among low-income nations. Consequently, the Nutrition Transition now occurs at lower levels of the gross national product than previously, and is accelerated further by high urbanization rates. Data from Asian nations, where diet structure is rapidly changing, suggest that diets higher in fats and sweeteners are also more diverse and more varied. Given that preferences for palatable diets are a universal human trait, fat consumption may be governed not by physiological mechanisms but by the amount of fat available in the food supply. Whereas economic development has led to improved food security and better health, adverse health effects of the Nutrition Transition include growing rates of childhood obesity. The implications of these trends are explored.

technology transport globalization and the Nutrition Transition food policy
Food Policy, 2006Co-Authors: Barry M. PopkinAbstract:Abstract Diet and activity have been affected by the rapid worldwide shifts in technological innovations reducing energy expenditures during leisure, transportation, and work; globalized modern food processing, marketing and distribution techniques; global mass media. The increases occur increasingly in rural areas on all continents. The resultant global increase in obesity increasingly is shifting the burden of obesity to the poor. While few direct linkages between globalization of trade in goods, services, and technology can be directly linked to diet and activity, a strong case exists for globalization’s role as a key underlying force behind this stage of the Nutrition Transition.

Global dimensions and dynamics of the Nutrition Transition
South African Journal of Clinical Nutrition, 2005Co-Authors: Barry M. PopkinAbstract:Two historic processes of change occur simultaneously with or precede the Nutrition Transition. One is the demographic Transition -- the shift from a pattern of high fertility and mortality to one of low fertility and mortality (typical of modern industrialised countries). The second is the epidemiological Transition: the shift from a pattern of high prevalence of infectious disease associated with malNutrition periodic famine and poor environmental sanitation to one of high prevalence of chronic and degenerative disease associated with urban-industrial lifestyles. The Nutrition Transition is closely related to the other two Transitions. In particular in the last one or two decades of the 20th century large shifts have occurred in diet and in physical activity patterns. Modern societies seem to be converging on a diet high in saturated fats sugar refined foods low in fibre -- often termed the Western diet -- and on lifestyles characterised by lower levels of activity. These changes are reflected in Nutritional outcomes such as changes in average stature body composition and morbidity. (excerpt)

The Nutrition Transition in the Developing World
Development Policy Review, 2003Co-Authors: Barry M. PopkinAbstract:This article explores shifts in Nutrition Transition from the period termed the receding famine pattern to one dominated by Nutrition-related non- communicable diseases (NR-NCDs). It examines the speed of these changes summarises dietary and physical activity changes and provides some sense of the health effects and economic costs. The focus is on the lower- and middle-income countries of Asia Africa the Middle East and Latin America. The article shows that changes are occurring at great speed and at earlier stages of countries economic and social development. The burden of disease from NR-NCDs is shifting towards the poor and the costs are also becoming greater than those for under- Nutrition. Policy options are identified. (authors)

Development and evaluation of a Nutrition Transition-FFQ for adolescents in South India.
Public health nutrition, 2017Co-Authors: Nida I. Shaikh, Reynaldo Martorell, Jennifer K. Frediani, Usha Ramakrishnan, Shailaja S. Patil, Kathryn M. Yount, K.m. Venkat Narayan, Solveig A. CunninghamAbstract:Objective To develop and evaluate a Nutrition Transition-FFQ (NT-FFQ) to measure Nutrition Transition among adolescents in South India. Design We developed an interviewer-administered NT-FFQ comprising a 125-item semi-quantitative FFQ and a twenty-seven-item eating behaviour survey. The reproducibility and validity of the NT-FFQ were assessed using Spearman correlations, intra-class correlation coefficients (ICC), and levels of agreement using Bland–Altman and cross-classification over 2 months (NT-FFQ1 and NT-FFQ2). Validity of foods was evaluated against three 24-h dietary recalls (24-HR). Face validity of eating behaviours was evaluated through semi-structured cognitive interviews. The reproducibility of eating behaviours was assessed using weighted kappa ( κ w ) and cross-classification analyses. Setting Vijayapura, India. Subjects A representative sample of 198 adolescents aged 14–18 years. Results Reproducibility of NT-FFQ: Spearman correlations ranged from 0·33 (pulses) to 0·80 (red meat) and ICC from 0·05 (fruits) to 1·00 (tea). On average, concordance (agreement) was 60 % and discordance was 7 % for food groups. For eating behaviours, κ w ranged from 0·24 (eating snacks while watching television) to 0·67 (eating lunch at home) with a mean of 0·40. Validity of NT-FFQ: Spearman correlations ranged from 0·11 (fried traditional foods) to 0·70 (tea) and ICC ranged from 0·02 (healthy global foods) to 1·00 (grains). The concordance and discordance were 48 % and 8 %, respectively. Bland–Altman plots showed acceptable agreement between NT-FFQ2 and 24-HR. The eating behaviours had acceptable face validity. Conclusions The NT-FFQ has good reproducibility and acceptable validity for food intake and eating behaviours. The NT-FFQ can quantify the Nutrition Transition among Indian adolescents.
