Abstract

BACKGROUND

The sustainability of diets consumed by African populations under socio-economic transition remains to be determined. This study developed and characterized a multi-dimensional Sustainable Diet Index (SDI) reflecting healthfulness, climate-friendliness, sociocultural benefits, and financial affordability using individual-level data of adults in rural and urban Ghana and Ghanaian migrants in Europe to identify the role of living environment in dietary sustainability.

METHODS

We used cross-sectional data from the multi-centre Research on Obesity and Diabetes among African Migrants Study (N = 3169; age range: 25-70 years). For the SDI construct (0-16 score points), we used the Diet Quality Index-International, food-related greenhouse gas emission, the ratio of natural to processed foods, and the proportion of food expenditure from income. In linear regression analyses, we estimated the adjusted ß-coefficients and 95% confidence intervals (CIs) for the differences in mean SDI across study sites (using rural Ghana as a reference), accounting for sociodemographic and lifestyle factors.

RESULTS

The overall mean SDI was 8.0 (95% CI: 7.9, 8.1). Participants in the highest SDI-quintile compared to lower quintiles were older, more often women, non-smokers, and alcohol abstainers. The highest mean SDI was seen in London (9.1; 95% CI: 8.9, 9.3), followed by rural Ghana (8.2; 95% CI: 8.0, 8.3), Amsterdam (7.9; 95% CI: 7.7, 8.1), Berlin (7.8; 95% CI: 7.6, 8.0), and urban Ghana (7.7; 95% CI: 7.5, 7.8). Compared to rural Ghana, the differences between study sites were attenuated after accounting for age, gender and energy intake. No further changes were observed after adjustment for lifestyle factors.

CONCLUSION

The multi-dimensional SDI describes four dimensions of dietary sustainability in this Ghanaian population. Our findings suggest that living in Europe improved dietary sustainability, but the opposite seems true for urbanization in Ghana.

摘要

背景

社会经济转型背景下非洲人群饮食的可持续性仍有待确定。本研究利用加纳农村和城市成年人以及欧洲加纳移民的个体层面数据，开发并描述了一个反映健康程度、气候友好性、社会文化效益和经济可承受性的多维可持续饮食指数（SDI），以确定生活环境在饮食可持续性中的作用。

方法

我们使用了多中心非洲移民肥胖与糖尿病研究的横断面数据（N = 3169；年龄范围：25 - 70岁）。对于SDI构建（0 - 16分），我们使用了国际饮食质量指数、与食物相关的温室气体排放、天然食品与加工食品的比例以及食物支出占收入的比例。在线性回归分析中，我们估计了各研究地点平均SDI差异的调整后β系数和95%置信区间（CI）（以加纳农村为参照），并考虑了社会人口学和生活方式因素。

结果

总体平均SDI为8.0（95%CI：7.9，8.1）。与较低五分位数相比，SDI最高五分位数的参与者年龄更大，女性更多，不吸烟且戒酒。伦敦的平均SDI最高（9.1；95%CI：8.9，9.3），其次是加纳农村（8.2；95%CI：8.0，8.3）、阿姆斯特丹（7.9；95%CI：7.7，8.1）、柏林（7.8；95%CI：7.6，8.0）和加纳城市（7.7；95%CI：7.5，7.8）。与加纳农村相比，在考虑年龄、性别和能量摄入后，各研究地点之间的差异有所减弱。在调整生活方式因素后未观察到进一步变化。
