Sugar consumption and global prevalence of obesity and hypertension: an ecological analysis

Abstract

Objective: The nutrition transition model provides an integrated approach to analyse global changes in food consumption and lifestyle patterns. Whether variability in food availability for consumption, lifestyle and sociodemographic factors is associated with the worldwide prevalence distribution of overweight, obesity and hypertension is unclear. Design: Ecological analysis. Setting: Country-specific prevalence estimates of overweight, obesity and hypertension were obtained. Prevalence estimates were then matched to yearand country-specific food and energy availability for consumption of cereals, sugar, sweeteners and honey, vegetable oils, fruits, starchy roots, pulses, total vegetables, alcoholic beverages, total meat, animal fat, eggs, milk, and fish and seafood. The per capita Gross Domestic Product (GDP), urbanization rates and prevalence of physical inactivity for each country were also obtained. Subjects: The overweight, obesity and hypertension databases included information from 128, 123 and seventy-nine countries, respectively. Results: Consumption of sugar and animal products were directly associated with GDP and urbanization rates. In a multivariate regression model, physical inactivity (B 5 0?01, SE 5 0?005, P 5 0?003), cereal consumption (B 5 20?02, SE 5 0?006, P , 0?001) and sugar consumption (B 5 0?03, SE 5 0?01, P 5 0?03) were significant predictors of obesity prevalence. Midpoint age (B 5 0?21, SE 5 0?10, P 5 0?02), prevalence of overweight (B 5 0?18, SE 5 0?08, P 5 0?02) and consumption of cereals (B 5 20?22, SE 5 0?10, P 5 0?02) were significant predictors of hypertension. Women appeared to have a significant obesity excess compared with men. Conclusions: High sugar consumption and sedentary lifestyle are associated with increased obesity prevalence. The non-linear association of sugar consumption with prevalence of obesity suggests that effective strategies to reduce its consumption may have differential effects in countries at different stages of the nutrition transition.

Meat consumption providing a surplus energy in modern diet contributes to obesity prevalence: an ecological analysis

“…This means that errors are reduced but some inaccuracies related to reporting quality may still be present in the data. Similar data from the same sources were recently used to analyse the relationships between nutrients and obesity [31,32] and diabetes [33][34][35] in a number of publications.…”

A comparison study on the prevalence of obesity and its associated factors among city, township and rural area adults in China

“…This was consistent with the ecological study of the UK and other previous studies. [24][25][26] Also, a Swiss study found a positive association between obesity and salt intake. 27 This was also consistent with the policy and action on nutrition and health promotion in many countries.…”

Risk factor assessment for breast cancer in North Cyprus: a comprehensive case-control study of Turkish Cypriot women

“…In addition to metabolic syndromes, excessive sugar consumption is associated with several types of cancers, including BC (29,30). High sugar consumption in addition to inactive lifestyle is also associated with the higher prevalence of obesity (31). An additional spoon of sugar consumed daily is thought to be associated with 14% increased risk of being overweight or obese (32).…”
