Growing urbanisation in Africa is accompanied by rapid changes in food environments, with potential shifts towards unhealthy food/beverage consumption, including in socio-economically disadvantaged populations. This study investigated how unhealthy food and beverages are embedded in everyday life in deprived areas of two African countries, to identify levers for context relevant policy. Deprived neighbourhoods (Ghana: 2 cities, Kenya: 1 city) were investigated (total = 459 female/male, adolescents/adults aged ≥13 y). A qualitative 24hr dietary recall was used to assess the healthiness of food/beverages in relation to eating practices: time of day and frequency of eating episodes (), length of eating episodes (), and who people eat with and where (). Five measures of the healthiness of food/beverages in relation to promoting a nutrient-rich diet were developed: i. nutrients (energy-dense and nutrient-poor -EDNP/energy-dense and nutrient-rich -EDNR); and ii. unhealthy food types (fried foods, sweet foods, sugar sweetened beverages (SSBs). A structured meal pattern of three main meals a day with limited snacking was evident. There was widespread consumption of unhealthy food/beverages. SSBs were consumed at three-quarters of eating episodes in Kenya (78.5%) and over a third in Ghana (36.2%), with those in Kenya coming primarily from sweet tea/coffee. Consumption of sweet foods peaked at breakfast in both countries. When snacking occurred (more common in Kenya), it was in the afternoon and tended to be accompanied by a SSB. In both countries, fried food was an integral part of all mealtimes, particularly common with the evening meal in Kenya. This includes consumption of nutrient-rich traditional foods/dishes (associated with cultural heritage) that were also energy-dense: (>84% consumed EDNR foods in both countries). The lowest socio-economic groups were more likely to consume unhealthy foods/beverages. Most eating episodes were <30 min (87.1% Ghana; 72.4% Kenya). Families and the home environment were important: >77% of eating episodes were consumed at home and >46% with family, which tended to be energy dense. Eating alone was also common as >42% of eating episodes were taken alone. In these deprived settings, policy action to encourage nutrient-rich diets has the potential to prevent multiple forms of malnutrition, but action is required across several sectors: enhancing financial and physical access to healthier foods that are convenient (can be eaten quickly/alone) through, for example, subsidies and incentives/training for local food vendors. Actions to limit access to unhealthy foods through, for example, fiscal and advertising policies to dis-incentivise unhealthy food consumption and SSBs, especially in Ghana. Introducing or adapting food-based dietary guidelines to incorporate advice on reducing sugar and fat at mealtimes could be accompanied by cooking skills interventions focussing on reducing frying/oil used when preparing meals, including 'traditional' dishes and reducing the sugar content of breakfast.
非洲城市化进程的加快伴随着食物环境的迅速变化,包括社会经济弱势群体在内的人群有可能转向不健康的食品/饮料消费。本研究调查了不健康的食品和饮料是如何融入两个非洲国家贫困地区的日常生活中的,以确定与背景相关的政策杠杆。对贫困社区(加纳:2个城市;肯尼亚:1个城市)进行了调查(共459名男女青少年/成年人,年龄≥13岁)。采用定性的24小时饮食回顾法,根据饮食行为评估食品/饮料的健康程度:用餐时间、用餐次数()、用餐时长()以及与谁一起用餐和在哪里用餐()。制定了五项与促进营养丰富饮食相关的食品/饮料健康程度衡量标准:i. 营养素(能量密集且营养匮乏 - EDNP/能量密集且营养丰富 - EDNR);ii. 不健康食品类型(油炸食品、甜食、含糖饮料(SSB))。明显呈现出一日三餐为主且零食有限的结构化用餐模式。不健康食品/饮料的消费很普遍。肯尼亚四分之三的用餐场合(7
